Clinical profile and outcomes in cervical cancer: An audit from a tertiary cancer center

Background: Carcinoma cervix contributes to a major proportion of cancer treatment in tertiary oncology centers. The outcomes are dependent on multiple factors. We conducted an audit to establish the pattern of treatment practiced for carcinoma cervix at the institute and suggest changes thereof to improve the quality of care. Methodology: A retrospective observational study of 306 diagnosed cases of carcinoma cervix was carried out for the year 2010. Data was collected with regards to diagnosis, treatment, and follow-up. Statistical analysis was performed using Statistical Package for Social Sciences (SPSS) version 20. Results: Out of 306 cases, 102 (33.33%) patients received only radiation therapy and 204 (66.66%) patients received concurrent chemotherapy. The most common chemotherapy used was weekly cisplatin 99 (48.52%), followed by weekly carboplatin 60 (29.41%) and three weekly cisplatin 45 (22.05%). Disease-free survival (DFS) at 5 years was 36.6% with patients of overall treatment time (OTT) of <8 weeks and >8 weeks showing DFS of 41.8% and 34% (P = 0.149), respectively. Overall survival (OS) was 34%. Concurrent chemoradiation improved overall survival by a median of 8 months (P = 0.035). There was a trend towards improved survival with three weekly cisplatin regimen, however, insignificant. Stage correlated with improved overall survival significantly with stage I and II showing 40% and stage III and IV showing 32% (P < 0.05) OS. Acute toxicity (grade I-III) was higher in the concurrent chemoradiation group (P < 0.05). Conclusion: This audit was a first of its kind in the institute and threw light on the treatment and survival trends. It also revealed the number of patients lost to follow-up and prompted us to review the reasons for it. It has laid the foundation for future audits and recognized the importance of electronic medical records in the maintenance of data

Comparison of short-term efficacy of neoadjuvant immunotherapy combined with chemotherapy and neoadjuvant chemoradiation for locally advanced resectable esophageal squamous cell carcinoma / 中国胸心血管外科临床杂志

@#Objective    To investigate the short-term therapeutic effect of neoadjuvant immunotherapy combined with chemotherapy in the locally advanced esophageal squamous cell carcinoma. Methods    The clinical data of patients with esophageal squamous cell carcinoma treated with neoadjuvant treatment in Gaozhou People's Hospital from August 2019 to October 2020 were retrospectively analyzed. According to the different treatments, the patients were divided into two groups: a neoadjuvant immunotherapy combined with chemotherapy group (NIC group) and a neoadjuvant chemoradiotherapy group (NC group). The baseline data, incidence of adverse events during treatment, perioperative indicators, postoperative pathological remission rate and incidence of postoperative complications were compared between the two groups. Results    Totally 33 patients were enrolled, including 15 males and 18 females, with an average age of 62.37±7.99 years. There were 17 patients in the NIC group and 16 patients in the NC group. In the NIC group, the carcinoma was mainly located in the middle and lower esophagus, with 5 paitents in stage Ⅱ, 9 patients in stage Ⅲ, and 3 patients in stage Ⅳa. In the NC group, the carcinoma was mainly located in the upper-middle esophagus, with 1 patient in stage Ⅱ and 15 patients in stage Ⅲ. During the neoadjuvant treatment, there was no significant difference in the occurrence of bone marrow suppression or gastrointestinal reactions between the two groups (P>0.05). There were 4 immune-related rashes in the NIC group and 1 esophageal perforation in the NC group. Fourteen (82.35%) patients in the NIC group and 12 (75.00%) patients in the NC group completed the operation on schedule. The postoperative ICU stay time and chest tube indwelling time in the NIC group were shorter than those in the NC group (P<0.05). There were 5 patients of complete remission in the NIC group, and 6 patients in the NC group. There was no significant difference in the pathological regression grade or residual tumor cells between the two groups (P>0.05). There was no significant difference in the incidence of anastomotic fistula, thoracic gastric fistula, bronchial mediastinal fistula, abdominal distension, pulmonary infection, stroke, or hoarseness during the perioperative period between the two groups of patients who completed the operation (P>0.05). In the NC group, 2 patients died during the perioperative period because of thoracic gastric fistula complicated by severe infection. Conclusion    Neoadjuvant immunotherapy combined with chemotherapy dose not significantly increase the occurrence of adverse events and shows a good rate of pathological remission, which indicates that the neoadjuvant immunotherapy combined with chemotherapy is a safe, feasible and potential new treatment model.

Study of radiotherapy dose effect of neoadjuvant chemotherapy versus concurrent chemoradiotherapy in cervical cancer / 中华放射肿瘤学杂志

Objective:To compare the effect of neoadjuvant chemotherapy vs. concurrent chemoradiotherapy on the target volume and organs at risk for locally advanced bulky (>4 cm) cervical cancer. Methods:From March 1, 2019 to June 30, 2021, 146 patients pathologically diagnosed with cervical cancer were selected and randomly divided into two groups using random number table method: the neoadjuvant chemotherapy (NACT) + concurrent chemoradiotherapy (CCRT) group ( n=73) and CCRT group ( n=73). Patients in the NACT+CCRT group received 2 cycles of paclitaxel combined with cisplatin NACT, followed by CCRT, the chemotherapy regimen was the same as NACT. In the CCRT group, CCRT was given. Statistical description of categorical data was expressed by rate. The measurement data between two groups were compared by Wilcoxon rank-sum test for comparison of two independent samples, and the rate or composition ratio of two groups was compared by χ2 test. Results:Before radiotherapy, GTV in the NACT+CCRT group was (31.95±25.96) cm 3, significantly lower than (71.54±33.59) cm 3 in the CCRT group ( P<0.01). Besides, CTV and PTV in the NACT+CCRT group were also significantly lower compared with those in the CCRT group (both P<0.05). In terms of target volume dosimetry, D 100GTV, D 95CTV, V 100GTV, V 100CTV and V 95PTV in the NACT+CCRT group were significantly higher than those in the CCRT group (all P<0.05). The complete remision (CR) rates in the NACT+CCRT and CCRT groups were 86.3% and 67.6%, with statistical significance between two groups ( P<0.01) . Regarding organs at risk, NACT+CCRT group significantly reduced the dose to the bladder, rectum, small intestine and urethra compared with CCRT group (all P<0.05). Conclusions:NACT can reduce the volume of tumors in patients with large cervical masses, increase the radiation dose to tumors, reduce the dose to organs at risk, and make the three-dimensional brachytherapy easier. Therefore, NACT combined with CCRT may be a new choice for patients with locally advanced cervical cancer with large masses.

A study on treatment of locally advanced squamous cell carcinoma of head and neck with radiation along with cisplatin or gefitinib

Background: Cisplatin based Concurrent chemo-radiation (CTRT) is the corner stone for treatment of locally advanced head and neck carcinoma. Epidermal growth factor receptor(EGFR) expression by squamous cell carcinoma which is associated with cancer development and progression,leads to emergence of anti-EGFR agents as a therapeutic option. In this study we compare cisplatin based CTRT against gefitinib based CTRT in terms of disease control and acute toxicity profile. Material and Methods: Stage III and IV squamous cell carcinoma of Head and neck region (excluding nasopharynx) were randomised into two groups. Control group received conventionally fractionated radiotherapy of 66Gy in 33fractions, over six and half weeks with concurrent weekly cisplatin. Study group received same dose of radiation with concurrent daily oral Gefitinib. All patients were followed up weekly during the treatment and then 6-8 weeks after completion of treatment and thereafter 3 monthly. Results: Overall response rate (complete response + partial response) was comparable for both arms (75% vs 76.2%, p value-0.881). Radiation with cisplatin was associated with significantly higher skin (28.6% vs 15%,p value-0.037) and mucosal (23.8% vs 5%,p-value-0.047) toxicities. Gefitinib containing arm showed significantly higher grade 3 diarrhoea (10% vs 0%, p-value-0.01) and skin rash (6% vs 0%, p -value-<0.001).With a median follow-up of 12.5 months Disease free survival (DFS) was not significantly different between the arms(12 vs 13 months). Conclusion: Gefitinib based CTRT is non-inferior to cisplatin based CTRT for the treatment of locally advanced head and neck carcinoma with acceptable toxicity profile.

Immunoexpressão das proteínas DEK e Fosfo-P38 no câncer retal antes da quimiorradioterapia / Immunoexpression of dek and phospho-p38 proteins in rectal cancer before chemoradiation therapy

ABSTRACT Background: Colorectal cancer is the third cause of cancer worldwide and a quarter of them are in the rectum. DEK oncogene is involved in several nuclear processes and can accelerate tumorigenesis. Objective: This study aims to evaluate the immunoexpression of DEK and Phospho-P38 proteins before neoadjuvant therapy in patients with rectum adenocarcinoma and correlate it with a clinical response and survival. Methods: Patients with adenocarcinoma of the middle and low rectum who underwent chemotherapy and radiotherapy followed by surgical tumor resection were included. The expression and quantification were studied by immunohistochemistry in the tumor biopsy tissues using a HScore system. Score ≥4 were considered positive and those with <4 negative. Results: 22 patients were included with a mean age of 63.55 years (SD: ±13.49). The clinical-stage before treatment was T3 on 72.7%, T4 on 18.2%, 31.8% were N1, 50% N0 and all M0. After chemo and radiotherapy, 54.6% were T3; 22.7% were classified as T2; 9.1% as T1, and 13.6% were T0. Among the tumors, 22.7% were positive for DEK and 63.6% positive for Phospho-P38. There was a positive correlation between DEK protein before treatment and pTNM stage (P=0.011). Phospho-P38 protein showed no correlation with these parameters. Patients with a negative HScore had a mean survival of 141.33 months (95%CI: 112.41-170.25) and those with a positive HSscore had a mean survival of 25.10 months (95%CI: 17.36-32.84; P<0.001). Conclusion: A higher expression of DEK was observed in advanced stages. Patients who presented DEK expression <4 had a higher survival, being a factor of worst prognosis.

RESUMO Contexto: O câncer colorretal é mundialmente, a terceira causa de câncer e um quarto destes estão localizados no reto. O oncogene DEK está envolvido em vários processos nucleares e pode acelerar a tumorigênese. Objetivo: Este estudo tem como objetivo avaliar a imunoexpressão das proteínas DEK e Fosfo-P38 antes da terapia neoadjuvante em pacientes com adenocarcinoma de reto e correlacioná-la com resposta clínica e sobrevida. Métodos: Foram incluídos pacientes com adenocarcinoma de reto médio e baixo submetidos à quimio e radioterapia seguida de ressecção cirúrgica do tumor. A expressão e quantificação foram estudadas por imuno-histoquímica nos tecidos de biópsia tumoral utilizando um sistema HScore. Escores ≥4 foram considerados positivos e aqueles com <4 negativos. Resultados: Foram incluídos 22 pacientes com média de idade de 63,55 anos (DP: ±13,49). O estágio clínico antes do tratamento era T3 em 72,7%, T4 em 18,2%, 31,8% eram N1, 50% N0 e todos M0. Após a quimio e radioterapia, 54,6% eram T3; 22,7% eram T2; 9,1% eram T1 e 13,6% T0. Entre os tumores, 22,7% foram positivos para DEK e 63,6% positivos para Phospho-P38. Houve uma correlação positiva para a imunoexpressão da proteína DEK e o estágio pTNM (P=0,011). A proteína fosfo-P38 não apresentou correlação com esses parâmetros. Pacientes com HScore negativo para DEK tiveram sobrevida média de 141,33 meses (IC95%: 112,41-170,25) e aqueles com HScore positivo tiveram sobrevida média de 25,10 meses (IC95%: 17,36-32,84) (P<0,001). Conclusão: Observou-se maior expressão de DEK em estágios avançados. Os pacientes que apresentaram expressão de DEK <4 tiveram maior sobrevida, sendo um fator de pior prognóstico.

A prospective comparative study of concurrent chemoradiation in advanced carcinoma cervix patients with weekly cisplatin vs. weekly cisplatin and paclitaxel

Background: Cisplatin-based concurrent chemoradiation is the standard treatment for carcinoma cervix. However, there is a need to explore alternative chemotherapeutic agents to further improve the treatment outcome. In this study, weekly paclitaxel and cisplatin-based chemoradiation was compared with weekly cisplatin-based chemoradiation in terms of disease control and toxicity profile. Materials and Methods: Sixty-four patients with FIGO stage IB2-IIIB squamous cell carcinoma of the uterine cervix were divided (by simple random sampling) into two groups: control arm patients who received radiotherapy (50 Gy in 25 fractions over 5 weeks) with concurrent weekly cisplatin (40 mg/m 2 ) and study arm patients received same radiation dose with weekly cisplatin (30 mg/m2 ) and paclitaxel (40 mg/m2 ). After that, all patients received brachytherapy 21 Gy/three fractions, one fraction/week. All patients were followed up weekly during treatment, then 4–6 weeks after treatment completion, and thereafter monthly for at least 6 months. Results: The overall treatment response (complete+ partial response) was numerically higher in the cisplatin- containing control arm, but not significant (93% vs. 80%, P-value = 0.406). High-grade early rectal (60% vs. 25%, P-value = 0.014) and acute gastrointestinal toxicity (66% vs. 6%, P-value <0.001) were significantly higher in the cisplatin and paclitaxel-containing arm. Hematological, renal, late rectal, and bladder toxicities were also numerically higher in the study arm, but not statistically significant. Conclusion: There was no significant benefit of weekly paclitaxel and cisplatin as an alternative to weekly cisplatin-based chemoradiation in the treatment of carcinoma cervix.

Consolidation chemoradiation (cCTRT) improves survival in responders to first?line chemotherapy (CT) in locally advanced gallbladder cancer (LA?GBC): A new standard of Care?

Introduction: Chemotherapy (CT) is the standard of care in advanced gallbladder cancer (GBC). Should locally advanced GBC (LA-GBC) with response to CT and good performance status (PS) be offered as consolidation chemoradiation (cCTRT) to delay progression and improve survival? There is a scarcity of literature on this approach in the English literature. We present our experience with this approach in LA-GBC. Materials and Methods: After obtaining ethics approval, we reviewed the records of consecutive GBC patients from 2014 to 2016. Out of 550 patients, 145 were LA-GBC who were initiated on chemotherapy. A contrast-enhanced computed tomography (CECT) abdomen was done to evaluate the response to treatment, according to the RECIST (Response Evaluation Criteria in Solid Tumors) criteria. All responders to CT (PR and SD) with good PS but unresectable were treated with cCTRT. Radiotherapy was given to GB bed, periportal, common hepatic, coeliac, superior mesenteric, and para-aortic lymph nodes up to a dose of 45 to 54 Gy in 25 to 28 fractions along with concurrent capecitabine at the rate of 1,250 mg/m2. Treatment toxicity, overall survival (OS), and factors affecting OS were computed based on Kaplan–Meier and Cox regression analysis. Results: The median age of patients was 50 years (interquartile range [IQR] = 43–56 years), and men to women ratio was 1:3. A total of 65% and 35% patients received CT and CT followed by cCTRT, respectively. The incidence of Grade 3 gastritis and diarrhea was 10% and 5%, respectively. Responses were partial response (PR; 65%), stable disease (SD; 12%), progressive disease (PD; 10%), and nonevaluable (NE; 13%) because they did not complete six cycles of CT or were lost to follow-up. Among PR, 10 patients underwent radical surgery (six after CT and four after cCTRT). At a median follow-up of 8 months, the median OS was 7 months with CT and 14 months with cCTRT (P = 0.04). The median OS was 57 months, 12 months, 7 months, and 5 months for complete response (CR) (resected), PR/SD, PD, and NE (P = 0.008), respectively. OS was 10 months and 5 months for Karnofsky performance status (KPS) >80 and <80 (P = 0.008), respectively. PS (hazard ratio [HR] = 0.5), stage (HR = 0.41), and response to treatment (HR = 0.05) were retained as independent prognostic factors.

Treatment outcomes of concurrent weekly cisplatin with intracavitary brachytherapy in patients with cervical carcinoma, pre-treated with concurrent chemo-radiotherapy

Objective: Cervical carcinoma is one of the leading causes of cancer-related deaths. This study evaluates improvement of quality of life, response to treatment, and compliance of concurrent weekly cisplatin with intracavitary brachytherapy (ICRT) in patients with cervical carcinoma, pre-treated with concurrent chemo- radiotherapy. Materials and Methods: This study was conducted in the Department of Radiotherapy, Government Medical College, from October 2018 to March 2020, meeting specified inclusion and exclusion criteria; patients willing to participate in the study were included. Results: On analyzing the pattern of response, 91.0% of patients have a complete response. The incidence of nausea and vomiting was observed at grade 1 or 2 in 80.0% of patients, grade 3 in 17.0% of patients, and more than grade 3 in 3.0% of patients. Neutropenia is occurred at less than grade 3 in 30.0% of patients and grade 3 or more in 3.3% of patients. Vaginal mucositis was also observed in 85.0% of the patients in less than grade 3 and 11.6% in grade 3 or more. The incidence of renal dysfunction less than grade 3 was seen in 35.0% of the patients and grade 3 or more in 5.0% of the patients. After 6months, there was cystitis found in less than grade 3 in 10.0% of the patients and more than grade 3 in 3.3% of the patients. Conclusion: In locally advanced squamous cell carcinoma of the uterine cervix, the addition of concurrent injection of cisplatin to ICRT significantly improves locoregional response but increases the incidence of hematological and mucosal toxicity, which is manageable.

Proteinemia as a Prognostic Factor in Colorectal Cancers beyond Surgery and Chemotherapy

Background: Globally, 1,096,601, 704,376, and 48,541 new colon, rectum, and anus cancer cases were recorded in 2018, respectively. Besides, 551,269, 310,394 and 19,129 cases of colon, rectum, and anus cancer deaths occurred in the same year. As a result, these cancers ranked in the third level of cancer incidence, and in the second level of cancer mortality. As it is known, all cancer patients are subjected to cancerinduced and therapy-induced nutritional deficiencies (mainly of proteins and calories). The present study aimed to assess proteins level in colorectal cancer (CRC) patients who underwent surgery and chemotherapy. Methods: A combined retrospective and prospective study was performed. The present study enrolled 100 CRC patients with their data on surgical procedures and chemotherapy management. Assessments of the studied samples were conducted as a baseline before receiving chemotherapy and preoperatively as P0, while the period after that was termed as P1. The serum samples were collected to measure protein concentration. Total Protein Kit, Micro was used. Results: The mean age of the patients was 50.7±12.88 years old. Only 8% had a positive CRC family history. Rectosigmoid cancer represented the most frequent site, figured in 41% of the cases, followed by rectum cancer. Multiple sites of CRC metastasis were recorded in 15% of the patients. All patients received chemoradiation. Folinic acid (leucovorin), 5-FU, and oxaliplatin (FOLFOX) was the most used regimen, administered in 40% of the patients. Oxaliplatin and capecitabine (also called Xeloda) (XELOX) were administered in 14% of the patients. Folinic acid (leucovorin), 5-FU, oxaliplatin, and irinotecan (FOLFOXIRI) were administered in 16% of the patients. Single-agent oxaliplatin or carboplatin were administered in 6% of the patients, each. 5-FU plus leucovorin was administered to 12% of the patients. Three patients received irinotecan, and oxaliplatin (IROX). One patient received folinic acid (leucovorin), 5-FU and irinotecan (FOLFIRI). Also, Gemzar was administered to two patients only. A total of 80% of the patients underwent several surgical procedures. Anterior perineal resection (APR) and total mesorectal excision (TME) were the most common two surgeries, performed in 20 and in 30% of the patients, respectively. In P0 status, 44% of the patients suffered from low protein levels, and 13% of the patients were within the normal level. These findings were statistically different (p=0.03). After CRC management (i.e., P1 status), 70% of the patients had protein deficiency. These results have strong significant differences (p=0.000). The mean of protein concentration declined gradually after management, from 8.82±0.9 μg/L to 6.210.78 μg/L, with a strong association between a reduction in proteins levels towards deficiency and surgical procedures and chemotherapy protocols (p=0.000). Conclusion: The incidence of CRC is increasing annually, and the chance of being diagnosed with this type of cancer has risen in recent years. In the present study, the male to female ratio was 1:1.5, and the 5th decade of life was themost common age for the diagnosis of CRC. A negative family history and bowel inflammatory diseases (IBD) history did not exclude people from exposure to the incidence of CRC. Colorectal cancer with localized and moderately differentiated adenocarcinoma were the most common types in the present work. Tumor distance from the anal verge seems to be very important and plays a significant role in the choosing of surgical intervention types and chemoradiation protocols. Colorectal cancer acts as a complex condition and, in addition to its management, nutritional state influences it in different mechanisms. Most patients suffered from hypoproteinemia after surgery and chemoradiation. As a result, alteration in the treatment outcomes, delaying in wound healing, and an increase in postoperative complications may occur. (AU)

Evaluation of survival of patients with locally advanced head and neck cancer treated in a single center / Avaliação da sobrevida de pacientes com câncer de cabeça e pescoço localmente avançado tratados em um único centro

Abstract Introduction: Even with improved treatment outcomes with multimodality approaches, the question of what is the best initial treatment for locally advanced head and neck cancer still remains unanswered. Objective: To review the overall survival of a large cohort of head and neck cancer, patients with locally advanced head and neck cancer treated in a single institution. Material and methods: We studied a cohort of patients with locally advanced head and neck cancer treated in our institution in the last fifteen years. To gather a large sample of patients with adequate follow-up time, a cross-check between ours and Fundação Oncocentro de São Paulo databases were done. We included patients with head and neck cancer, clinical or pathological staging III or IV, treated with surgery followed by radiotherapy or surgery plus chemoradiation or radiotherapy alone or chemoradiation alone. Results: 796 patients with locally advanced head and neck cancer were included, 88% male, 44% age >60 years and 76% stage IV. The tumor location was the oral cavity (34%), oropharynx (27%), hypopharynx (17%) and larynx (17%). The treatment groups were chemoradiation alone (39.7%), surgery plus chemoradiation (26.3%), surgery followed by radiotherapy (18.5%) and radiotherapy alone (15.5%). Comparing the clinical variables between the treatment groups significant differences in age and clinical stage were observed. With a median follow up of 7.5 years (1-16 years), for the entire cohort, the overall survival at 5 and 10 years was 34.8% and 28%. The overall survival at 5 and 10 years was 16.7% and 12.2% for radiotherapy alone, 38.8% and 26.3% for surgery followed by radiotherapy, 28% and 16.6% for chemoradiation alone, and 37.3% and 23.2% for surgery plus chemoradiation. The staging IV (p = 0.03) and radiotherapy alone (p = 0.05), had a worst survival in multivariate analysis. Surgical groups vs. chemoradiation alone had no significant difference for overall survival. Conclusion: The present study is the largest cohort of locally advanced head and neck cancer of Brazilian patients to evaluate treatment outcomes. Although there were significant clinical differences between surgical and radiotherapy groups, surgery or chemoradiation alone as the initial treatment resulted in no significant difference in survival.

Os grupos de tratamento foram quimiorradioterapia (39,7%), cirurgia seguida de radioterapia ou quimiorradioterapia (26,3%), cirurgia seguida de radioterapia (18,5%) e radioterapia isolada (15,5%). Comparando as variáveis clínicas entre os grupos de tratamento, foram observadas diferenças significativas de idade e estágio clínico. Com uma mediana de tempo de seguimento de 7,5 anos (1-16 anos) para toda a coorte, a sobrevida global em 5 e 10 anos foi de 34,8% e 28%. A sobrevida global em 5 e 10 anos foi de 16,7% e 12,2% para radioterapia isolada, 38,8% e 26,3% para cirurgia seguida de radioterapia, 28% e 16,6% para quimiorradioterapia e 37,3% e 23,2% para cirurgia seguida de radioterapia ou quimiorradioterapia. O estágio IV (p = 0,03) e a radioterapia isolada (p = 0,05) apresentaram pior sobrevida na análise multivariada. Grupos cirúrgicos versus quimiorradioterapia não apresentaram diferença significante para a sobrevida global. Conclusão: O presente estudo é a maior coorte de câncer de cabeça e pescoço localmente avançado de pacientes brasileiros para avaliação dos desfechos do tratamento. Embora houvesse diferenças clínicas significativas entre os grupos cirúrgico e radioterápico, a cirurgia ou a quimiorradioterapia, como tratamento inicial, não apresentaram diferenças significantes em relação à sobrevida.

Predictors of pathological response and clinical outcome following chemoradiation for locally advanced rectal cancer - a systematic review / Preditores de resposta patológica e de outcome clinico após quimioradioterapia neoadjuvante para cancro do reto localmente avançado - uma revisão sistemática

Abstract Background: Colorectal cancer is one of the most common types of cancer and is associated with a high lethality rate. Treatment is multidisciplinary, and neoadjuvant chemoradiation is recommended in locally advanced rectal cancer. About 15% of patients answer favorably to neoadjuvant chemoradiation, so it is important to determine the predictors of response. Objective: To review the results of studies that analyzes the predictors of complete pathological response to neoadjuvant chemoradiation in patients with locally advanced rectal cancer. Search methods: We searched for eligible articles in data bases Pubmed and Scopus, between the 12th and the 20th of March 2020. The following key words were used: "predictors of response", "chemoradiation" and "locally advanced rectal cancer". Selection criteria: Inclusion criteria: Studies including patients with locally advanced rectal cancer, patients receiving neoadjuvant chemoradiation as treatment, studies including predictors of response to neodjuvant chemoradiation, overall survival as an outcome and regarding language restrictions, only articles in English were accepted, only studies published until the 31st of December 2019 were accepted. Main results: Fourteen studies fulfilled the inclusion criteria. Thirteen are cohort studies and one is a clinical trial. Four groups of predictors were defined: blood markers, tumors, histopathological and patients' characteristics. Author's conclusions: During the analysis of the articles, there were several predictors identified as potential candidates for clinical practice, such as high pre neoadjuvant chemoradiation Carcinoembryonic Antigen levels and small post neoadjuvant chemoradiation tumor size. Nevertheless, it is difficult to make definitive conclusions about the most reliable predictors. That is why it is crucial to initiate further studies with standardized cut-off values and a methodology homogenization.

Resumo Introdução: O cancro colorretal é um dos cancros mais prevalentes em Portugal e tem associada uma alta taxa de letalidade. Atualmente, o tratamento é multidisciplinar, e a quimioradioterapia neoadjuvante está indicada no Cancro do Reto Localmente Avançado. Sabe-se que cerca de 15% dos doentes responde favoravelmente à quimioradioterapia neoadjuvante, sendo por isso importante determinar quais os preditores de resposta a este tipo de tratamento. Objetivo: Rever os resultados dos estudos que analisam os preditores de resposta completa à quimioradioterapia em pacientes com Cancro do Reto Localmente Avançado. Métodos de pesquisa: Pesquisamos artigos elegíveis nos bancos de dados Pubmed e Scopus, desde o dia 12 a 20 de Março de 2020. Foram utilizadas as seguintes palavras chave: "preditores de resposta", "quimioradioterapia neoadjuvante" e "Cancro do Reto Localmente Avançado". Critérios de seleção: Critérios de inclusão: Estudos que incluam pacientes com Cancro do Reto Localmente Avançad, pacientes sujeitos a quimioradioterapia neoadjuvante, preditores de resposta à quimioradioterapia, que avaliem a sobrevivência como outcome, escritos em inglês e publicados até dia 31 de Dezembro de 2019. Resultados principais: Catorze estudos preencheram os critérios de inclusão. De todos os artigos, treze são Cohort e um é Clinical Trial. Foram definidos quatro grupos de preditores: marcadores de sangue e caraterísticas do tumor, histopatológicas e dos pacientes. Conclusões dos autores: Durante a análise dos artigos, foram identificados vários preditores como potenciais candidates para a prática clínica, tais como o valor elevado de antigénio carcinoembrionário pré- quimioradioneoaajuvância e tamanho reduzido. Contudo, é arriscado elaborar conclusões concretas relativamente aos preditores mais confiáveis. Por isso, é crucial iniciar novos estudos com valores de cut-off estandardizados e métodos com maior homogeneidade.

Comparison of altered fractionation schedule with concurrent chemo-radiation for squamous cell carcinoma of head and neck

Background: Aim of the study was to compare the response of altered fractionation schedule with concurrent chemo-radiation in patients with primary and the nodal disease.Methods: Total of 40 patients (20 in each arm) with stage 1- 4 squamous cell carcinoma of the head and neck with a performance status of 0-2 (ECOG) were included in the study. Arm A was altered fractionation schedule where in patients received 6 fractions per week to a total dose of 6600 cGy in 33 fractions. In Arm B, patients received conventional radiotherapy with concurrent chemotherapy three weekly Inj. of cisplatin (100 mg/m2). Patients were evaluated for acute toxicity every week using the Acute Radiation Morbidity Scoring Criteria. The response was assessed after 6 weeks and 12 weeks post treatment using the RECIST criteria. Data was statistically analyzed.Results: Seventeen patients in Arm A and 18 patients in Arm B completed the treatment. At the end of three months, In Arm A, 7 patients had complete response and in Arm B, 9 patients had complete response of the primary (p>0.05).  When the complete nodal response was compared in both the arms, there was no difference (2 vs 4 in Arm A vs Arm B resp.). But there were more partial nodal responders in Arm B (p = 0.016). The acute toxicities were comparable in both the arms.Conclusions: Altered fraction radiotherapy can be used in early lesions with minimal nodal burden but with locally advanced disease or large nodal burden addition of chemotherapy should not be avoided.

Correlation of planning target volume with mucositis for head-and-neck cancer patients undergoing chemoradiation

Context: Head-and-neck cancer patients undergoing chemoradiation. Aims: The aim of the study was to see if there is any correlation between the planning target volume (PTV) and mucositis. Settings and Design: This was a single-arm prospective study. Subjects and Methods: A total of forty head-and-neck cancer patients undergoing chemoradiation were assessed for mucositis at the 5th week. The grades of mucositis were correlated with PTVs of low risk (54 Gy) and high risk (60–66 Gy). Statistical Analysis Used: The data were analyzed using the statistical software, SPSS Inc. Release 2009, predictive analytics software statistics for windows version 20.0, Chicago. Log transformation was done as the data were skewed. Independent t-test was used to compare between the two grades of toxicity. P <0.01 was considered for statistical significance. Results: The mean PTVlow risk was 522cc (228–771) and PTVhigh risk was 254cc (20–780). Grade II mucositis was seen in 27 (67%) patients and Grade III in 11 (28%) patients. The mean PTVlow risk was higher for patients, who had Grade III compared to Grade II mucositis (571 vs. 517 cc, P = 0.052). Conclusions: The same was seen for PTVhigh risk(367 vs. 222 cc, P = 0.017). PTV is a better predictor of mucositis, and those patients with larger PTV require close monitoring and early intervention of mucositis

The efficacy of an ayurvedic preparation of yashtimadhu (Glycyrrhiza glabra) on radiation-induced mucositis in head-and-neck cancer patients: A pilot study

Background: Oral mucositis is a common and debilitating painful side effect of many forms of chemotherapy and radiation therapy. Mucositis may lead to dose reductions and unplanned interruptions of chemotherapy and/or radiotherapy (RT) and often affects patients' quality of life. Aim: The objective of the study was to assess the efficacy of the ayurvedic preparation in decreasing the severity of mucositis in head-and-neck cancer patients receiving concomitant chemoradiotherapy. Materials and Methods: In this prospective randomized study, the patients were divided into three groups. Group 1 patients received conventional mucositis treatment, whereas Group 2 patients received ayurvedic preparation Yashtimadhu in addition to conventional treatment. Group 3 patients received honey for local application in oral cavity as well as one tea spoon of honey twice daily orally in addition to routine conventional treatment. All the patients were assessed for mucositis at the end of every week during the RT for a period of 6 weeks. Results: A significant difference was observed between the groups at each time point. Nearly 42.85% of patients in conventional treatment arm developed Grade 3 mucositis, 20% of patients developed Grade 3 mucositis in group where honey was given, and only 15.5% of patients developed Grade 3 mucositis in Yastimadhu group. Unplanned treatment breaks and hospitalization of patients were reduced with the use of yashtimadhu as compared to other two groups. Conclusion: Yashtimadhu was observed to be effective and delayed the development of severe form of mucositis. The drug appeared to be more efficient in the management of radiation-induced mucositis

A comparative study on concurrent chemoradiation using cisplatin versus carboplatin in the management of locoregionally advanced non-small cell lung cancer

Background: Concurrent chemoradiation is considered the standard care for locoregionally advanced non-small cell lung cancer. This study aimed to compare the treatment response, progression free survival and treatment toxicities between cisplatin and carboplatin based concurrent chemoradiation.Methods: Between October 2015 and September 2017, 60 eligible patients were enrolled and divided into two arms of 30 patients each. Arm A received EBRT to chest (60Gy/30 fractions) with concurrent weekly Injection Cisplatin 35mg/m2. Arm B received EBRT to chest (60Gy/30 fractions) with concurrent weekly Injection Carboplatin at a dose of AUC-2. Early treatment response was assessed at 1 month and late treatment response at 6 months after completion of radiation using RECIST criteria. Treatment toxicities was assessed using RTOG toxicity criteria. All statistical analysis was carried out using SPSS version 21.Results: Most patients were in the age range of 61-70 years. Mean age of presentation was 67.53±11.038 years in Arm A and 66.03±12.794 years in Arm B. Median follow up was 16 months for both arms. Response rate of was slightly better in Arm A (73.3% versus 60%). 1 year PFS rate was 53.33% in Arm A and 36.67% in Arm B. Median time to progression was better in Arm A (11 months vs 10 months). Toxicities were almost comparable in both the arms.Conclusions: Use of carboplatin in combination with radiation therapy is comparable to cisplatin in terms of treatment outcomes with better compliance and lower toxicity.

Estudio comparativo de los resultados del tratamiento del carcinoma anal escamoso en los pacientes HIV positivos y negativos / Comparative study of the results of the treatment of squamous anal carcinoma in HIV positive and negative patients

Introducción: El tratamiento del carcinoma anal escamoso (CAE) en los pacientes HIV positivos resulta controvertido. Si bien las guías actuales recomiendan realizar en los pacientes con buen estado inmunológico la quimiorradioterapia (QRT) concurrente estándar, algunos autores consideran que estos pacientes presentan mayor toxicidad y peores resultados a largo plazo, por lo que requerirían un abordaje diferente. El objetivo de este trabajo es comparar los resultados del tratamiento del CAE en los pacientes VIH positivos y negativos. Diseño: Estudio retrospectivo comparativo. Pacientes y métodos: Se revisaron retrospectivamente las historias clínicas de los pacientes tratados en el Sector Coloproctología, Hospital Fernández, entre 01/2007 y 10/2018. Los del conducto anal se dividieron en: Grupo I: VIH negativos y Grupo II: VIH positivos. Se compararon variables demográficas, factores de riesgo específicos, estadificación, QRT (drogas, toxicidad y respuesta), tratamiento quirúrgico curativo/paliativo, persistencia/recurrencia y supervivencia específica y global. Resultados: Se incluyeron 28 pacientes (18 mujeres); margen: 2, conducto: 26 (Grupo I: 15. Grupo II: 11). Los VIH positivos eran en su mayoría hombres que tienen sexo con hombres vs. 100% de mujeres VIH negativas (p<0,01), más jóvenes (45,2±0,9 vs. 63,6±8; p<0,01) y tabaquistas (82% vs. 27%; p=0,005). No hubo diferencia significativa en la estadificación, aunque el Grupo II tuvo tumores con complicaciones más severas. Pudieron completar el tratamiento: Grupo I: 93%, Grupo II: 64% (p<0,05). Tuvieron respuesta completa a la QRT 13/14 (93%) pacientes del Grupo I y 3/7 (43%) del Grupo II (p<0,01). Hubo 3 recurrencias, 2 locorregionales y 1 a distancia (p=NS). Los VIH positivos requirieron más cirugías (82% vs. 27%; p<0,01). A 5 pacientes (4 del Grupo II) se les realizó una resección abdominoperineal (RAP). Tuvieron colostomía definitiva, con o sin RAP, el 46% de los pacientes, la mayoría VIH positivos (82% vs. 27%; p=0,002). En los VIH positivos el RR de mortalidad por cáncer fue 4 (IC95%: 1,01-16,5; p=0,02) y el RR de mortalidad global fue 5,45 (IC95%: 1,42-20,8; p=0,002). Tuvieron menor supervivencia, tanto global (p=0,001) como libre de enfermedad (p=0,01). Mediana de seguimiento: 27 meses (4-216).Conclusiones: Los pacientes VIH positivos con CAE se diferenciaron de los VIH negativos en una menor tasa de respuesta completa a la QRT y una mayor necesidad de tratamiento quirúrgico. Además, tuvieron una supervivencia global y libre de enfermedad significativamente menor que los VIH negativos. (AU)

INTRODUCTION: The treatment of anal squamous cell carcinoma (SCC) in HIV-positive patients is controversial. Although current guidelines recommend performing standard concurrent chemoradiotherapy (CRT) in patients with good immune status, some authors believe that these patients have greater toxicity and worse long-term results, so they would require a different approach. The purpose of this study was to compare the results of SCC treatment in HIV-positive and HIV-negative patients.DESIGN: Comparative retrospective study.PATIENTS AND METHODS: The records of patients treated in the Coloproctology Section, Hospital Fernández, between 01/2007 and 10/2018 were retrospectively reviewed. Those of the anal canal were divided into: Group I: HIV-negative and Group II: HIV-positive. Demographic variables, specific risk factors, staging, CRT (drugs, toxicity, and response), curative/palliative surgical treatment, persistence/recurrence, and cancer-specific and global survival were compared.RESULTS: 28 patients (18 women), margin: 2, conduit: 26 (Group I: 15. Group II: 11). The HIV-positive were mostly men who have sex with men (vs. 100% HIV-negative women; p<0.01), younger (45.2 ± 0.9 vs. 63.6 ± 8; p<0.01) and smokers (82% vs. 27%; p=0.005). There was no significant difference in staging, although Group II had tumors with more severe complications. Completed the treatment: Group I: 93%, Group II: 64% of patients (p<0,05). Thirteen out of 14 (93%) patients in Group I, and 3/7 (43%) patients in Group II had a complete response to CRT (p<0.01). There were 3 recurrences, 2 loco-regional and 1 distance (p=NS). HIV-positive required more surgery (82% vs. 27%; p<0.01). 5 patients (4 of Group II) underwent an abdominal-perineal resection (APR). Forty six percent of patients had permanent colostomy, with or without APR, most of them were HIV-positive (82% vs. 27%; p=0.002). In HIV-positive patients, the RR of cancer mortality was 4 (95% CI: 1.01-16.5; p=0.02) and the RR of overall mortality was 5.45 (95% CI: 1.42-20, 8; p=0.002). They also had lower overall (p=0.001) and disease-free survival (p=0.01). Median follow-up: 27 months (4 - 216).CONCLUSION: HIV-positive patients with anal SCC were different from HIV-negative patients in that they had a lower complete response rate to CRT, and a greater need for surgical treatment. They had a significantly lower overall and disease-free survival than HIV-negative patients. (AU)

A Prospective Study on Concurrent Chemoradiation in Inoperable Carcinomas Esophagus

introduction: Despite many advances in both surgery and radiotherapy, the treatment of esophageal cancer remains a challenge for both surgeons and oncologists. The treatment of choice for patients with carcinoma esophagus is controversial. Recent studies have suggested that combined chemotherapy and radiation therapy may result in improved survival. Aim: The aim of our study was to analyze the role of concurrent chemoradiation in inoperable carcinomas esophagus. Materials and Methods: This single-arm prospective study was conducted in the Department of Radiotherapy, Thanjavur Medical College Hospital from August 2018 to August 2019 to analyze the role of concurrent chemoradiation in inoperable carcinomas esophagus. A total of 26 cases of inoperable cases of carcinoma esophagus were treated with once-weekly cisplatin 30 mg/ m2 along with radiotherapy 60 Gy in 30 fractions in 6 weeks on telecobalt machine. Results: Of 26 patients 16 patients were males, 10 patients were females, 17 patients had age <60 years, 9 patients had age above 61 years, 22 patients had squamous cell carcinoma, 4 patients had adenocarcinoma, 4 patients had lesion in upper part of esophagus, 14 patients had lesion in middle part, 8 patients had lesion in lower part, 4 patients had tumor dimension <5 cm, 22 patients had dimension >5.1 cm, 2 patients had tumor stage T1, 22 patients had T2, 2 patients had T3, 1 patient had Nx, 21 patients had No, 4 patients had N1, 15 patients had mild dysphagia, 8 patients had moderate dysphagia, 3 patients had severe dysphagia1 patients had diarrhea, 1 patient had fatigue, 4 patients had leukopenia, and 1 patient had neutropenia. Conclusion: Combined modality therapy plays a significant role in the treatment of patients with carcinoma esophagus. Concurrent chemoradiation is a superior treatment in inoperable carcinoma esophagus in terms of local control and survival. Hence, concurrent chemoradiation can also be tried in early cases and surgical morbidity survival and quality of life can be improved.

A prospective study comparing induction chemotherapy followed by chemoradiation versus chemoradiation alone in stage III non-small cell lung cancer

Background: Although concurrent chemoradiation (CCRT) is the standard of care for stage III non-small cell lung cancer(NSCLC), the five years overall (OS) survival is very poor. Most of the patients developed distant metastasis later which can be improved by induction chemotherapy. Aims: This study was designed to observe the difference in epidemiology, acute toxicities, overall responses [complete response (CR)+partial response (PR)] after treatment completion, disease-free survival (DFS) and progression-free survival (PFS) at the end of the study. Settings and Design: This was a prospective, interventional, randomized hospital-based study. Methods and Material: Eligible patients were randomized into arm A (CCRT with weekly paclitaxel(P) + Carboplatin(C) with 66 Gray radiation) and arm B (two cycles of induction chemotherapy consisted of P+C followed by CCRT as of arm A. During treatment weekly, after completion of treatment at 6th week and thereafter 3 monthly evaluation was done till the end of study. S tatistical analysis used: Chi-Square and Fisher Exact test did statistical analysis, t-test with 95%CI, Kaplan Meier survival analysis, Log Rank test using SPSS version 18. Results: Among 44 patients, male (88.6%), Smokers (85.1%) were predominant with the most common histology was squamous cell carcinoma (52.4%). Overall response (Complete Response +Partial Response) was higher in Arm B 66.66% but statistically non-significant. Acute toxicities in both the arms were comparable and similar. DFS and PFS in the induction chemotherapy arm (Arm B) were numerically superior to concurrent chemoradiation arm (Arm A) but statistically nonsignificant Conclusion: To conclude there were no significant differences in results between two arms in the present study population. Further studies with the larger sample size and longer duration of follow up are necessary.
