RESUMO

Objective: To explore the application and efficacy of paclitaxel liposome in the treatment of advanced breast cancer among Chinese population in the real world. Methods: The clinical characteristics of patients with advanced breast cancer who received paclitaxel liposome as salvage treatment from January 1, 2016 to August 31, 2019 in 11 hospitals were collected and retrospectively analyzed. The primary outcome was progression free survival (PFS), and the secondary outcome included objective response rate (ORR) and safety. The survival curve was drawn by Kaplan-Meier analysis and the Cox regression model were used for the multivariate analysis. Results: Among 647 patients with advanced breast cancer who received paclitaxel liposome, the first-line treatment accounted for 43.3% (280/647), the second-line treatment accounted for 27.7% (179/647), and the third-line and above treatment accounted for 29.1% (188/647). The median dose of first-line and second-line treatment was 260 mg per cycle, and 240 mg in third line and above treatment. The median period of paclitaxel liposome alone and combined chemotherapy or targeted therapy is 4 cycles and 6 cycles, respectively. In the whole group, 167 patients (25.8%) were treated with paclitaxel liposome combined with capecitabine±trastuzumab (TX±H), 123 patients (19.0%) were treated with paclitaxel liposome alone (T), and 119 patients (18.4%) were treated with paclitaxel liposome combined with platinum ± trastuzumab (TP±H), 108 patients (16.7%) were treated with paclitaxel liposome combined with trastuzumab ± pertuzumab (TH±P). The median PFS of first-line and second-line patients (5.5 and 5.5 months, respectively) were longer than that of patients treated with third line and above (4.9 months, P<0.05); The ORR of the first line, second line, third line and above patients were 46.7%, 36.8% and 28.2%, respectively. Multivariate analysis showed that event-free survival (EFS) and the number of treatment lines were independent prognostic factors for PFS. The common adverse events were myelosuppression, gastrointestinal reactions, hand foot syndrome and abnormal liver function. Conclusion: Paclitaxel liposomes is widely used and has promising efficacy in multi-subtype advanced breast cancer.

RESUMO

OBJECTIVE@#To investigate the effect of Chaihu Guizhi Decoction (CHGZD) combined with capecitabine on growth and apoptosis of subcutaneous triple-negative breast cancer xenografts in nude mice and explore the possible mechanism.@*METHODS@#Nude mouse models bearing subcutaneous triple-negative breast cancer xenografts were randomized into 6 groups (n=10) for treatment with distilled water (model group), low (10.62 g/kg), medium (21.23 g/kg) and high (42.46 g/kg) doses of CHGZD, capecitabine (0.2 mg/kg), or the combination of CHGZD (42.46 g/kg) and capecitabine (0.2 mg/k) once daily for 21 consecutive days. The general condition of mice was observed, and after 21-day treatments, the tumors were dissected for measurement of tumor volume and weight and histopathological examination with HE staining. Serum IL-6 levels of the mice were determined with enzyme-linked immunosorbent assay (ELISA), and the expression levels of IL-6, STAT3, p-STAT3, Bax, Bcl-2 and cyclin D1 in the tumor tissues were detected using real-time PCR and Western blotting.@*RESULTS@#Compared with those in the model group, the tumor-bearing mice receiving treatments with CHGZD showed significantly increased food intake with good general condition, sensitive responses, increased body weight, and lower tumor mass (P < 0.01). Compared with capecitabine treatment alone, treatment with CHGZD alone at the medium and high doses and the combined treatment all resulted in significantly higher tumor inhibition rates (P < 0.01), induced obvious tumor tissue degeneration and reduced the tumor cell density. Treatments with CHGZD, both alone and in combination with capecitabine, significantly decreased serum IL-6 level, lowered the mRNA expression levels of IL-6 and STAT3, the protein expressions of IL-6, STAT3 and P-STAT3 (P < 0.05), and the mRNA and protein expressions of Bcl-2 and cyclin D1 (P < 0.05), and increased the mRNA and protein expressions of Bax in the tumor tissues (P < 0.05).@*CONCLUSION@#CHGZD combined with capecitabine can significantly inhibit tumor growth in nude mice bearing triple-negative breast cancer xenografts, the mechanism of which may involve the inhibition of IL-6/STAT3 signaling pathway and regulation of Bax, Bcl-2 and cyclin D1 expressions to suppress tumor cell proliferation and differentiation and induce cell apoptosis.

RESUMO

La mitad de los pacientes con cáncer de origen colorrectal desarrollan metástasis hepáticas durante el curso de su enfermedad y de esas el 80% son irresecables. La resecabilidad se define no por la extensión de la hepatectomía, sino por la función del hígado remanente, por lo que para pacientes con ciertos factores favorables se pueden realizar técnicas de remodelación hepática para aumentar el volumen del hígado remanente para que este sea suficiente. La hepatectomía en dos tiempos se basa en procedimientos secuenciales que buscan tratar metástasis hepáticas colorrectales consideradas inicialmente irresecables, logrando la resección completa de las mismas dejando un remanente hepático funcionante suficiente, lo cual no sería posible en un solo acto quirúrgico. El objetivo de este trabajo es presentar el caso clínico de un paciente portador de metástasis hepáticas sincrónicas de origen colorrectal irresecables, que luego de una quimioterapia de conversión, con el fin de aumentar el futuro remanente hepático y evitar falla hepática postoperatoria y realizar una resección oncológica, fue sometido a una hepatectomía en dos tiempos, técnica utilizada con baja frecuencia en nuestro medio, destacando una evolución favorable, con marcadores tumorales en valores normales y sin evidencia imagenológica de recaída local ni sistémica.


Half of colorectal cancer patients develop liver metastases during the course of their disease, 80% of which are unresectable. Resectability is defined not by the extent of the hepatectomy, but by the function of the liver remnant. Therefore, for patients with certain factors, liver remodeling techniques can be performed to increase volume of the remaining liver so that it is sufficient. Two-stage hepatectomy is performed on colorectal liver metastases which are initially considered unresectable in one stage resection procedures, in which sequential procedures are performed in order to achieve complete resection and preserve a sufficient functioning liver remnant. The objective of this paper is to present the case of a patient with unresectable synchronous colorectal liver metastases, in which after conversion chemotherapy, in order to increase the future liver remnant, avoid postoperative liver failure and perform an oncological resection underwent a two-stage hepatectomy, a technique used with low frequency in our setting, highlighting a favorable evolution, with tumor markers in normal values and without imaging evidence of local or systemic relapse.


Metade dos pacientes com câncer colorretal desenvolve metástases hepáticas durante o curso da doença e, desses, 80% são irressecáveis. A ressecabilidade é definida não pela extensão da hepatectomia, mas pela função do fígado remanescente; portanto, para pacientes com certos fatores favoráveis, técnicas de remodelação hepática podem ser realizadas para aumentar o volume do fígado remanescente de forma que seja suficiente. A hepatectomia em dois estágios é baseada em procedimentos sequenciais que buscam tratar metástases hepáticas colorretais inicialmente consideradas irressecáveis, obtendo ressecção completa, deixando um remanescente hepático funcional suficiente, o que não seria possível em um único ato cirúrgico. O objetivo deste trabalho é apresentar o caso clínico de um paciente com metástases hepáticas sincrônicas irressecáveis ​​de origem colorretal, que após quimioterapia de conversão, com o objetivo de aumentar o futuro remanescente hepático e evitar insuficiência hepática pós-operatória e realizar uma ressecção oncológica, foi submetido a dois Hepatectomia em estágio, técnica utilizada com baixa frequência em nosso meio, evidenciando evolução favorável, com marcadores tumorais em valores normais e sem evidências de imagem de recidiva local ou sistêmica.

RESUMO

Objective: To explore the safety and efficacy of oxaliplatin plus capecitabine (CapeOX) or oxaliplatin plus S-1 (SOX) regimen neoadjuvant chemotherapy in the treatment of advanced gastric cancer. Methods: A retrospective cohort study was performed. Clinical data of patients diagnosed as advanced gastric cancer undergoing CapeOX/SOX neoadjuvant chemotherapy and standard laparoscopic radical operation for gastric cancer in Ruijin Hospital of Shanghai Jiaotong University School of Medicine from April 2016 to April 2019 were retrospectively collected. Inclusion criteria were as follows: (1) age≥18 years; (2) gastric adenocarcinoma was confirmed by histopathology and the clinical stage was T3-4aN+M0; (3) tumor could be resectable; (4) preoperative neoadjuvant chemotherapy was CapeOX or SOX regimen without radiotherapy or other regimen chemotherapy; (5) no other concurrent malignant tumor; (6) the Eastern Cooperative Oncology Group (ECOG) score ≤ 1; (7) no bone marrow suppression; (8) normal liver and kidney function. Exclusion criteria were as follows: (1) patients with recurrent gastric cancer; (2) patients receiving emergency surgery due to tumor perforation, bleeding, obstruction, etc.; (3) allergy to oxaliplatin, S-1, capecitabine or any drug excipients; (4) diagnosed with coronary heart disease, cardiomyopathy, or the New York Heart Association class III or IV; (5) pregnant or lactating women. A total of 118 patients were enrolled as the neoadjuvant chemotherapy group, and 379 patients with locally advanced gastric cancer who received surgery combined with postoperative adjuvant chemotherapy over the same period simultaneously were included as the adjuvant chemotherapy group. After propensity score matching was performed including gender, age, ECOG score, tumor site, clinical stage, chemotherapy regimen and other factors by 1:1 ratio, there were 40 cases in each group. The differences between the two groups in general conditions, efficacy of neoadjuvant chemotherapy, intraoperative conditions, postoperative conditions, histopathological results, chemotherapy-related adverse events, and survival status were compared and analyzed. Results: Comparison of baseline demographics between the two groups showed no statistically significant difference (all P>0.05). In the neoadjuvant chemotherapy group, 5.0% (2/40) of patients achieved clinical complete response, 57.5% (23/40) achieved partial response, 32.5% (13/40) remained stable disease, and 5.0% (2/40) had disease progression before surgery. Objective response rate was 62.5% (25/40), and disease control rate was 95.0% (38/40). There were no statistically significant differences between neoadjuvant chemotherapy group and adjuvant chemotherapy group in terms of operation time, intraoperative blood loss, number of lymph node harvested, length of postoperative hospital stay, and postoperative mortality and morbidity (all P>0.05). Postoperative complications were well managed with conservative treatment. No Clavien-Dindo IV or V complications were observed in both groups. Pathological results showed that the proportion of patients with pathological stage T1 in the neoadjuvant chemotherapy group was significantly higher than that in the adjuvant chemotherapy group [27.5% (11/40) vs. 5.0% (2/40)], while the proportion of patients with pathological stage T3 was significantly lower than that in the adjuvant chemotherapy group [20.0% (8/40) vs. 45.0% (18/40)], with statistically significant difference (χ(2)=15.432, P=0.001). In the neoadjuvant chemotherapy group, there were 4 cases of tumor regression grade 0, 8 cases of grade 1, 16 cases of grade 2, and 12 cases of grade 3. The pathological complete response rate was 10% (4/40), the overall pathological response rate was 70.0% (28/40). There was no statistically significant difference in the incidence of chemotherapy-related adverse events between neoadjuvant chemotherapy group and adjuvant chemotherapy group [40% (16/40) vs. 37.5% (15/40), P>0.05). There were no statistically significant differences in OS (43 months vs. 40 months) and 3-year OS rate (66.1% vs. 59.8%) between neoadjuvant chemotherapy group and adjuvant chemotherapy group (P=0.428). The disease-free survival (DFS) and 3-year DFS rates of the neoadjuvant chemotherapy group were significantly superior to those of the adjuvant chemotherapy group (36 months vs. 28 months, 51.4% vs. 35.8%, P=0.048). Conclusion: CapeOX or SOX regimen neoadjuvant chemotherapy is a safe, effective and feasible treatment mode for advanced gastric cancer without increasing surgical risk and can improve the DFS of patients.

RESUMO

Objective: To investigate the effectiveness, safety, and prognosis of neoadjuvant chemoradiotherapy (nCRT) for Siewert type II and III adenocarcinomas of the esophagogastric junction (AEG). Methods: This study is a prospective randomized controlled clinical study (NCT01962246). AEG patients who were treated at the Third Department of Surgery of the Fourth Hospital of Hebei Medical University from February 2012 to June 2016 were included. All of the enrolled patients were diagnosed with type II or III locally advanced AEG gastric cancer (T2-4N0-3M0 or T1N1-3M0) by gastroscopy and CT before operation; the longitudinal axis of the lesion was ≤ 8 cm; no anti-tumor treatment was previously given and no contraindications of chemotherapy and surgery were found. Case exclusion criteria: serious diseases accompanied by liver and kidney, cardiovascular system and other vital organs; allergy to capecitabine or oxaliplatin drugs or excipients; receiving any form of chemotherapy or other research drugs; pregnant or lactating women; patients with diseases resulting in difficulty to take capecitabine or with concurrent tumors. Based on sample size estimation, a total of 150 AEG patients were enrolled. Using the random number table method, the enrolled patients were divided into the nCRT group and the direct operation group with 75 cases in each group. The nCRT group received XELOX chemotherapy (capecitabine+ oxaliplatin) before surgery and concurrent radiotherapy (45 Gy, 25 times, 1.8 Gy/d, 5 times/week). Clinical efficacy of the nCRT group was evaluated by the solid tumor efficacy evaluation standard (RECIST1.1) and the tumor volume reduction rate was measured on CT. After completing the preoperative examination in the direct operation group, and 8-10 weeks after the end of nCRT in the nCRT group, surgery was performed. Laparoscopic exploration was initially performed. According to the Japanese "Regulations for the Treatment of Gastric Cancer", a transabdominal radical total gastrectomy combined with perigastric lymph node dissection was performed. The primary outcome was the 3-year overall survival (OS) and disease-free survival rate (DFS); the secondary outcomes were R0 resection rate, the toxicity of chemotherapy, and surgical complications. The follow-up ended on December 31, 2019. The postoperative recurrence, metastasis and survival time of the two groups were collected. Results: After excluding patients with incomplete clinical data, patients or family members requesting to withdraw informed consent, and those failing to follow the treatment plan, 63 cases in the nCRT group and 69 cases in the direct operation group were finally enrolled in the study. There were no statistically significant differences in baseline characteristics of the two groups (all P>0.05). Sixty-three patients in the nCRT group were evaluated by RECIST1.1 after treatment, the image based effective rate was 42.9% (27/63), and the stable disease rate was 98.4% (62/63); the tumor volume before and after nCRT measured on CT was (58.8±24.4) cm(3) and (46.6±25.7) cm(3), respectively, the effective rate of tumor volume reduction measured by CT was 47.6% (30/63). Incidences of neutrophilopenia [65.1% (41/63) vs. 40.6% (28/69), χ(2)=7.923, P=0.005], nausea [81.0% (51/63) vs. 56.5% (39/69), χ(2)=9.060, P=0.003] and fatigue [74.6% (47/63) vs. 42.0% (29/69), χ(2)=14.306, P=0.001] in the nCRT group were significantly higher than those in the direct surgery group. Radiation gastritis/esophagitis and radiation pneumonia were unique adverse reactions in the nCRT group, with incidences of 52.4% (33/63) and 15.9%(10/63), respectively. The classification of tumor regression of 63 patients in nCRT group presented as 11 cases of grade 0 (17.5%), 20 cases of grade 1 (31.7%), 28 cases of grade 2 (44.4%), and 5 cases of grade 3 (7.9%). Eleven (17.5%) patients achieved pathologic complete response. Sixty-one (96.8%) patients in the nCRT group underwent R0 resection, which was higher than 87.0% (60/69) in the direct surgery group (χ(2)=4.199, P=0.040). The mean number of harvested lymph nodes in the specimens in the nCRT group and the direct operation group was 27.6±12.4 and 26.8±14.6, respectively, and the difference was not statistically significant (t=-0.015, P=0.976). The pathological lymph node metastasis rate and lymph node ratio in the two groups were 44.4% (28/63) vs. 76.8% (53/69), and 4.0% (70/1 739) vs. 21.9% (404/1 847), respectively with statistically significant differences (χ(2)=14.552, P<0.001, and χ(2)=248.736, P<0.001, respectively). During a median follow-up of 52 (27-77) months, the 3-year DFS rate in the nCRT group and the direct surgery group was 52.4% and 39.1% (P=0.049), and the 3-year OS rate was 63.4% and 52.2% (P=0.019), respectively. According to whether the tumor volume reduction rate measured by CT was ≥ 12.5%, 63 patients in the nCRT group were divided into the effective group (n=30) and the ineffective group (n=33). The 3-year DFS rate of these two subgracps was 56.6% and 45.5%, respectively without significant difference (P=0.098). The 3-year OS rate was 73.3% and 51.5%,respectively with significant difference (P=0.038). The 3-year DFS rate of patients with the tumor regression grades 0, 1, 2 and 3 was 81.8%, 70.0%, 44.4%, and 20.0%, repectively (P=0.024); the 3-year OS rate was 81.8%, 75.0%, 48.1% and 40.0%, repectively (P=0.048). Conclusion: nCRT improves treatment efficacy of Siewert type II and III AEG patients, and the long-term prognosis is good.

RESUMO

Resumen Los tumores neuroendocrinos pancreáticos (TNEsP) son un grupo poco frecuente de neoplasias, pueden ser funcionales y causan síndromes clínicos diversos, o no funcionales, con síntomas secundarios a invasión a estructuras cercanas o enfermedad metastásica (1). Se presenta el caso de una paciente de 55 años con insulinoma maligno con compromiso metastásico extenso, no candidata a intervención quirúrgica, hipoglucemia de difícil manejo sin respuesta a tratamiento con diazóxido y prednisolona, y que requirió manejo con quimioterapia y embolización de metástasis hepáticas, con posterior mejoría clínica, estabilidad de la enfermedad por imágenes diagnósticas y retiro de medicamentos para manejo de hipoglucemia. En seguimiento presenta síntomas de hiperglucemia con HbA1c en 12%, con lo cual se diagnosticó diabetes mellitus de novo y se inició manejo con insulina.


Abstract Pancreatic neuroendocrine tumors (TNEP) are a rare group of neoplasms, which can secrete peptide hormones causing various clinical syndromes, or be non-secretory, with symptoms secondary to invasion of neighboring or distant structures (1). The case of a 55-year-old patient with malignant insulinoma with extensive metastatic involvement, not operable, with persistent hypoglycemia refractory to treatment with diazoxide and prednisolone, who received management with chemotherapy and embolization of liver metastases, achieving the withdrawal of medications for the management of hypoglycemia and a tumor response of stable disease in the comparison of images during the 12-month follow-up. During the 15th cycle of chemotherapy, he presented symptoms of hyperglycemia with HbA1c in 12%, with which diabetes de novo mellitus was diagnosed and insulin management was initiated.

RESUMO

PURPOSE: We conducted a randomized, multicenter, phase III trial to compare S-1 plus docetaxel (DS) with S-1 plus cisplatin (SP) as adjuvant chemotherapy for stage III gastric cancer patients. MATERIALS AND METHODS: Stage III gastric cancer patients who had received curative gastrectomy with D2 lymphadenectomy were randomized into equal groups to receive adjuvant chemotherapy of eight cycles of DS (S-1 70 mg/m2/day on days 1-14 plus docetaxel 35 mg/m2on days 1 and 8) every 3 weeks or SP (S-1 70 mg/m2/day on days 1-14 plus cisplatin 60 mg/m2on day 1) every 3 weeks. The primary endpoint was 3-year disease-free survival (DFS) rate. RESULTS: Between November 2010 and July 2013, 153 patients (75 patients to DS and 78 patients to SP) were enrolled from 8 institutions in Korea. After the capecitabine plus oxaliplatin was approved based on the CLASSIC study, itwas decided to close the study early. With a median follow-up duration of 56.9 months, the 3-year DFS rate between two groups was not significantly different (49.14% in DS group vs. 52.5% in SP group). The most common grade 3-4 adverse event was neutropenia (42.7% in DS and 38.5% in SP, p=0.351). SP group had more grade 3-4 anemia (1.3% vs. 11.5%, p=0.037), whereas grade 3-4 hand-foot syndrome (4.1% vs. 0%, p=0.025) and mucositis (10.7% vs. 2.6%, p=0.001) were more common in DS group. Fifty-one patients (68%) in DS group and 52 (66.7%) in SP group finished planned treatment. CONCLUSION: Our findings suggest that SP or DS is an effective and tolerable option for patients with curatively resected stage III gastric cancer.

RESUMO

PURPOSE: We investigated whether irinotecan plus capecitabine improved progression-free survival (PFS) compared with capecitabine alone in patients with human epidermal growth factor 2 (HER2) negative and anthracycline and taxane pretreated metastatic breast cancer (MBC). MATERIALS AND METHODS: A total of 221 patients were randomly assigned to irinotecan (80 mg/m2, days 1 and 8) and capecitabine (1,000 mg/m2 twice a day, days 1-14) or capecitabine alone (1,250 mg/m2 twice a day, days 1-14) every 3 weeks. The primary endpoint was PFS. RESULTS: There was no significant difference in PFS between the combination and monotherapy arm (median, 6.4 months vs. 4.7 months; hazard ratio [HR], 0.84; 95% confidence interval [CI], 0.63 to 1.11; p=0.84). In patients with triple-negative breast cancer (TNBC, n=90), the combination significantly improved PFS (median, 4.7 months vs. 2.5 months; HR, 0.58; 95% CI, 0.37 to 0.91; p=0.02). Objective response rate was numerically higher in the combination arm, though it failed to reach statistical significance (44.4% vs. 33.3%, p=0.30). Overall survival did not differ between arms (median, 20.4 months vs. 24.0 months; p=0.63). While grade 3 or 4 neutropenia was more common in the combination arm (39.6% vs. 9.0%), hand-foot syndrome was more often observed in capecitabine arm. Quality of life measurements in global health status was similar. However, patients in the combination arm showed significantly worse symptom scales especially in nausea/vomiting and diarrhea. CONCLUSION: Irinotecan plus capecitabine did not prove clinically superior to single-agent capecitabine in anthracycline- and taxane-pretreated HER2 negative MBC patients. Toxicity profiles of the two groups differed but were manageable. The role of added irinotecan in patients with TNBC remains to be elucidated.

RESUMO

PURPOSE: Simvastatin has demonstrated anti-tumor activity in preclinical studies via tumor cell senescence, apoptosis, and anti-angiogenesis. This phase II trial evaluated the efficacy and toxicity profile of conventional XELOX and bevacizumab chemotherapy plus simvastatin in metastatic colorectal cancer patients (MCRC). MATERIALS AND METHODS: Patients with MCRC received first-line XELOX in 3-week treatment cycles of intravenous oxaliplatin 130 mg/m² plus bevacizumab 7.5 mg/kg (day 1), followed by oral capecitabine 1,000 mg/m² twice daily (day 1-14). Simvastatin 80 mg tablets were taken orally once daily every day during the period of chemotherapy. The primary endpoint was progression-free survival (PFS). Secondary endpoints were response rate, duration of response, overall survival (OS), time to progression, and toxicity. RESULTS: From January 2014 to April 2015, 60 patients were enrolled and 55 patients were evaluable for tumor response. The median follow-up duration was 30.1 months (range, 28.5 to 31.7 months). The median PFS was 10.4 months (95% confidence interval [CI], 9.6 to 11.1). The median OS of all patients was 19.0 months (95% CI, 11.9 to 26.0). The disease-control rate and overall response rate were 88.3% (95% CI, 74 to 96) and 58.3% (95% CI, 44 to 77), respectively, by intent-to-treat protocol analysis. There was one complete response and 34 partial responses. One patient experienced grade 3 creatine kinase elevation and liver enzyme elevation. CONCLUSION: Based on the current study, the addition of 80 mg simvastatin to XELOX and bevacizumab showed comparable clinical efficacy in patients with MCRC as first-line chemotherapy and did not increase toxicity.

RESUMO

PURPOSE: Distant metastasis can occur early after neoadjuvant chemoradiotherapy (CRT) in patients with rectal cancer. This study was conducted to evaluate the clinical characteristics of patients who developed early systemic failure. METHODS: The patients who underwent neoadjuvant CRT for a rectal adenocarcinoma between June 2007 and July 2015 were included in this study. Patients who developed distant metastasis within 6 months after CRT were identified. We compared short- and long-term clinicopathologic outcomes of patients in the early failure (EF) group with those of patients in the control group. RESULTS: Of 107 patients who underwent neoadjuvant CRT for rectal cancer, 7 developed early systemic failure. The lung was the most common metastatic site. In the EF group, preoperative carcinoembryonic antigen was higher (5 mg/mL vs. 2 mg/mL, P = 0.010), and capecitabine as a sensitizer of CRT was used more frequently (28.6% vs. 3%, P = 0.002). Of the 7 patients in the EF group, only 4 underwent a primary tumor resection (57.1%), in contrast to the 100% resection rate in the control group (P < 0.001). In terms of pathologic outcomes, ypN and TNM stages were more advanced in the EF group (P < 0.001 and P = 0.047, respectively), and numbers of positive and retrieved lymph nodes were much higher (P < 0.001 and P = 0.027, respectively). CONCLUSION: Although early distant metastasis after CRT for rectal cancer is very rare, patients who developed early metastasis showed a poor nodal response with a low primary tumor resection rate and poor oncologic outcomes.

RESUMO

PURPOSE: To study the efficacy of capecitabine or S-1 plus oxaliplatin (CAPOX or SOX) for treating thymidine phosphorylase (TP)- or dihydropyrimidine dehydrogenase (DPD)-positive advanced gastric cancer.MATERIALS AND METHODS: Eighty-six patients with stage IIIC to IV gastric cancer were assessed for TP and DPD expression by immunohistochemistry. The association between CAPOX or SOX efficacy and TP/DPD expression was retrospectively analyzed.RESULTS: There were no significant differences in the objective remission rate (ORR, 52.27% vs. 47.62%; P>0.05), disease control rate (72.73% vs. 73.81%, P>0.05), progression-free survival (hazard ratio [HR], 1.119; 95% confidence interval [CI], 0.739–1.741; P=0.586), and overall survival (OS; HR, 0.855; 95% CI, 0.481–1.511; P=0.588) between CAPOX and SOX. A higher number of stage IV patients showed TP positivity, while DPD-positive patients predominantly showed intestinal type of gastric cancer. In TP-positive patients, the ORRs associated with CAPOX and SOX treatments were 57.14% and 38.10%, respectively; OS was better with CAPOX than with SOX (HR, 0.447; 95% CI, 0.179–0.978; P=0.046). Among DPD-positive patients, the SOX treatment-associated ORR (60.87%) was significantly higher than the CAPOX treatment-associated ORR (43.48%). Furthermore, SOX treatment resulted in better OS than did CAPOX treatment (HR, 2.020; 95% CI, 1.019–4.837; P=0.049).CONCLUSIONS: No significant difference in clinical efficacy was found between CAPOX and SOX. TP-positive patients might respond better to CAPOX while DPD-positive patients may respond better to SOX. Our findings might serve as a guide for personalized chemotherapy for gastric cancer.

RESUMO

PURPOSE: Identification of biomarkers to predict recurrence risk is essential to improve adjuvant treatment strategies in stage II/III gastric cancer patients. This study evaluated biomarkers for predicting survival after surgical resection. MATERIALS AND METHODS: This post-hoc analysis evaluated patients from the CLASSIC trial who underwent D2 gastrectomywith orwithout adjuvant chemotherapy (capecitabine plus oxaliplatin) at the Yonsei Cancer Center. Tumor expressions of thymidylate synthase (TS), excision repair cross-complementation group 1 (ERCC1), and programmed death-ligand 1 (PD-L1) were evaluated by immunohistochemical (IHC) staining to determine their predictive values. RESULTS: Among 139 patients, IHC analysis revealed high tumor expression of TS (n=22, 15.8%), ERCC1 (n=23, 16.5%), and PD-L1 (n=42, 30.2%) in the subset of patients. Among all patients, high TS expression tended to predict poor disease-free survival (DFS; hazard ratio [HR], 1.80; p=0.053), whereas PD-L1 positivity was associated with favorable DFS (HR, 0.33; p=0.001) and overall survival (OS; HR, 0.38; p=0.009) in multivariate Cox analysis. In the subgroup analysis, poor DFS was independently predicted by high TS expression (HR, 2.51; p=0.022) in the adjuvant chemotherapy subgroup (n=66). High PD-L1 expression was associated with favorable DFS (HR, 0.25; p=0.011) and OS (HR, 0.22; p=0.015) only in the surgery-alone subgroup (n=73). The prognostic impact of high ERCC1 expression was not significant in the multivariate Cox analysis. CONCLUSION: This study shows that high TS expression is a predictive factor for worse outcomes on capecitabine plus oxaliplatin adjuvant chemotherapy, whereas PD-L1 expression is a favorable prognostic factor in locally advanced gastric cancer patients.

RESUMO

PURPOSE: Clinical implications of single patient classifier (SPC) and microsatellite instability (MSI) in stage II/III gastric cancer have been reported. We investigated SPC and the status of MSI and Epstein-Barr virus (EBV) as combinatory biomarkers to predict the prognosis and responsiveness of adjuvant chemotherapy for stage II/III gastric cancer. MATERIALS AND METHODS: Tumor specimens and clinical information were collected from patients enrolled in CLASSIC trial, a randomized controlled study of capecitabine plus oxaliplatin-based adjuvant chemotherapy. The results of nine-gene based SPC assay were classified as prognostication (SPC-prognosis) and prediction of chemotherapy benefit (SPC-prediction). Five quasimonomorphic mononucleotide markers were used to assess tumor MSI status. EBV-encoded small RNA in situ hybridization was performed to define EBV status. RESULTS: There were positive associations among SPC, MSI, and EBV statuses among 586 patients. In multivariate analysis of disease-free survival, SPC-prognosis [hazard ratio (HR): 1.879 (1.101–3.205), 2.399 (1.415–4.067), p=0.003] and MSI status (HR: 0.363, 95% confidence interval: 0.161–0.820, p=0.015) were independent prognostic factors along with age, Lauren classification, TNM stage, and chemotherapy. Patient survival of SPC-prognosis was well stratified regardless of EBV status and in microsatellite stable (MSS) group, but not in MSI-high group. Significant survival benefit from adjuvant chemotherapy was observed by SPC-Prediction in MSS and EBV-negative gastric cancer. CONCLUSION: SPC, MSI, and EBV statuses could be used in combination to predict the prognosis and responsiveness of adjuvant chemotherapy for stage II/III gastric cancer.

RESUMO

Objective: To assess whether extended time intervals (8-12, 13-20 and >20 weeks) between the end of neoadjuvant chemoradiotherapy and surgery affect overall survival, disease-free survival. Materials and methods: Retrospective study in 120 patients with rectal adenocarcinoma without evidence of metastasis (T1-4/N0-2/M0) at the time of diagnosis that underwent surgery with curative intent after neoadjuvant chemoradiotherapy with capecitabine and obtained R0 or R1 resection between January 2010 to December 2014 at the National Cancer Institute of Peru. Dates were evaluated by Kaplan-Meier method, log- rank test and Cox regression analysis. Results: Of the 120 patients, 70 were women (58%). The median age was 63(26-85) years. All received neoadjuvant chemoradiotherapy. No significant difference was found between the association of the median radial (0.6, 0.7 and 0.8 cm; p=0.826) and distal edge (3.0, 3.5 and 4.0 cm; p=0.606) with time interval groups and similarly the mean resected (18.8, 19.1 and 16.0; p=0.239) and infiltrated nodules (1.05, 1.29 and 0.41); p=0.585). The median follow-up time of overall survival and desease free survival was 40 and 37 months, respectively. No significant differences were observed in overall survival (79.0%, 74.6% and 71.1%; p=0.66) and disease-free survival (73.7%, 68.1% and 73.6%; p=0.922) according to the three groups studied at the 3-year of follow-up. Conclusions: We found that widening the time intervals between the end of neoadjuvant chemoradiotherapy and surgery at 24 weeks does not affect the overall survival, disease-free survival and pathological outcomes. It allows to extend the intervals of time for future studies that finally will define the best time interval for the surgery


Objetivo: Evaluar si los intervalos de tiempo extendidos (8-12, 13-20 y >20 semanas) entre el fin de la quimioradioterapia neoadyuvante y la cirugía afectan la sobrevida global, y la sobrevida libre de enfermedad. Material y métodos: Estudio retrospectivo de 120 pacientes con adenocarcinoma rectal sin evidencia de metástasis (T1-4/N0-2/M0) al momento del diagnóstico que se sometieron a cirugía con intención curativa luego de quimioradioterapia neoadyuvante con capecitabina y tuvieron resección R0 o R1 entre enero 2010 y diciembre 2014 en el Instituto Nacioanal de Enfermedades Neoplásicas de Perú. El análisis se hizo con el método de Kaplan-Meier, la prueba log-rank y la regresión de Cox. Resultados: De 120 pacientes, 70 fueron mujeres (58%). La mediana de la edad fue 63 años (26-85 años). Todos recibieron quimioradioterapia neoadyuvante. No hubo diferencia significativa entre la asociación de las medianas de los bordes radial (0,6, 0.7 y 0,8 cm; p=0,826) y distal (3,0, 3,5 y 4,0 cm; p=0,606) con los intervalos de tiempo de los grupos y similarmente con la media de los ganglios resecados (18,8, 19,1 y 16,0; p=0,239) e infiltrados (1,05, 1,29 y 0,41; p=0,585). No se observaron diferencias significativas en sobrevida global (79,0%, 74,6% y 71,1%; p=0,66) y sobrevida libre de enfermedad (73,7%, 68,1% y 73,6%; p=0,922), en los tres grupos estudiados a 3 años de seguimiento. Conclusiones: Encontramos que aumentar los intervalos de tiempo entre el fin de la quimioradioterapia neoadyuvante y la cirugía hasta 24 semanas no afecta la sobrevida global, sobrevida libre de enfermedad ni los desenlaces patológicos. Esto permitiría extender los intervalos de tiempo en estudios futuros para definir el mejor intervalo de tiempo para la cirugía

RESUMO

PURPOSE: We aimed to discuss the roles of radiation and chemotherapy as adjuvant treatment in patients with staged IB GC who were enrolled in the adjuvant chemoradiotherapy in stomach tumors (ARTIST) trial. MATERIALS AND METHODS: Among the 458 patients who were enrolled in the ARTIST trial, 99 had stage IB disease. The patients were randomly assigned to receive either adjuvant chemoradiotherapy with capecitabine plus cisplatin (XP, n=50) or chemoradiotherapy (XPRT, n=49). Survival analyses were performed in accordance with the AJCC 2010 staging system. RESULTS: According to the AJCC 2010 system, stage migration from IB to II occurred in 71% of the patients; 98% of the T2 N0 cases were reclassified as T3 N0, and 42% of the T1 N1 cases were reclassified as T1 N2. When comparing survival outcomes between the XPRT and XP arms for stage IB cancer (AJCC 2002), no significant difference in 5-year disease-free survival (DFS) between the 2 arms was found. (median 5-year DFS, not reached, P=0.256). The patients classified as having stage IB cancer (AJCC 2002) and reclassified as having stage II cancer (AJCC 2010) exhibited worse prognoses than those who remained in stage IB, although the difference was not statistically significant (5-year DFS rate, 83% vs. 93%). When we compared 5-year DFS in 70 patients with stage II (AJCC 2010), the addition of radiotherapy to XP chemotherapy did not show better outcome than XP alone (P=0.137). CONCLUSIONS: The role of adjuvant chemoradiotherapy in the treatment of stage IB GC (AJCC 2002) warrants further investigation.

RESUMO

PURPOSE: To investigate the current status of adjuvant chemotherapy (AC) regimens in Korea and the difference in efficacy of AC administered by surgical and medical oncologists in patients with stage II or III gastric cancers. MATERIALS AND METHODS: We performed a retrospective observational study among 1,049 patients who underwent curative resection and received AC for stage II and III gastric cancers between February 2012 and December 2013 at 29 tertiary referral university hospitals in Korea. To minimize the influence of potential confounders on selection bias, propensity score matching (PSM) was used based on binary logistic regression analysis. The 3-year disease-free survival (DFS) rates were compared between patients who received AC administered by medical oncologists or surgical oncologists. RESULTS: Between February 2012 and December 2013 in Korea, the most commonly prescribed AC by medical oncologists was tegafur/gimeracil/oteracil (S-1, 47.72%), followed by capecitabine with oxaliplatin (XELOX, 16.33%). After performing PSM, surgical oncologists (82.74%) completed AC as planned more often than medical oncologists (75.9%), with statistical significance (P=0.036). No difference in the 3-year DFS rates of stage II (P=0.567) or stage III (P=0.545) gastric cancer was found between the medical and surgical oncologist groups. CONCLUSIONS: S-1 monotherapy and XELOX are a main stay of AC, regardless of whether the prescribing physician is a medical or surgical oncologist. The better compliance with AC by surgical oncologists is a valid reason to advocate that surgical oncologists perform the treatment of AC for stage II or III gastric cancers.

RESUMO

The present study evaluated the survival impact of standard adjuvant chemotherapy and prognostic differences between Epstein-Barr virus (EBV)-associated gastric cancer (EBVaGC) and EBV-negative gastric cancer (EBVnGC). A total of 276 patients were enrolled according to the following criteria: 1) pathologically diagnosed with primary gastric adenocarcinoma, 2) test results from EBV-encoded RNA in situ hybridization, 3) stage II/III according to the 7th edition of UICC/AJCC staging system for gastric cancer, and 4) postoperative adjuvant chemotherapy. Fifty-nine (21.4%) and 217 (78.6%) patients exhibited EBVaGC and EBVnGC, respectively, while 129 (46.7%) patients were classified as stage II and 147 (53.3%) as stage III. As for adjuvant chemotherapy, 87 (31.5%) patients received capecitabine and oxaliplatin, while 189 (68.5%) received S-1 monotherapy. With a median follow-up duration of 21.3 (6.4-89.0) months, the estimated 3-year disease-free survival (DFS) and overall survival (OS) rates were 74.8% and 83.0%, respectively. In univariate analysis and multivariate analysis using a Cox proportional hazard model including age, gender, stage, Lauren classification, and the type of chemotherapy, EBV-positivity was not significantly associated with DFS (p-value= 0.630) regardless of the type of chemotherapy. Therefore, no association was found between EBV positivity and the survival outcomes in patients with curatively resected gastric cancer who received standard adjuvant chemotherapy.

RESUMO

In 2017, 10 topics were selected as major clinical research advances in gynecologic oncology. For cervical cancer, efficacy and safety analysis results of a 9-valent human papillomavirus (HPV) vaccine and long-term impact of reduced dose of quadrivalent vaccine were updated. Brief introduction of KEYNOTE trials of pembrolizumab, a monoclonal antibody that blocks the interaction between programmed death (PD)-1 and its ligands, PD-L1 and PD-L2, followed. Tailored surveillance programs for gynecologic cancer related with Lynch syndrome and update on sentinel lymph node mapping were reviewed for uterine corpus cancer. For ovarian cancer, 5 topics were selected including poly(ADP-ribose) polymerases inhibitors and immunotherapy. The other potential practice changers covered in this review were lymphadenectomy in advanced disease, secondary cytoreductive surgery in recurrent disease, weekly dose-dense regimen for first-line chemotherapy, incorporation of bevacizumab maintenance in platinum-sensitive recurrent disease, and effect of platinum-free interval prolongation. Conflicting opinions of academic societies on periodic pelvic examination were introduced in conjunction with relevant literature review. For the field of radiation oncology, results of 2 big trials, The Postoperative Radiation Therapy in Endometrial Carcinoma-3 and Gynecologic Oncology Group-258, for endometrial cancer and recent advance in high-dose-rate brachytherapy for cervical cancer were reported. Topics for breast cancer covered adjuvant capecitabine after preoperative chemotherapy, adjuvant pertuzumab and trastuzumab in early human epidermal growth factor receptor 2-positive disease, olaparib for metastatic cancer in patients with a germline BRCA mutation, 20-year risks of recurrence after stopping endocrine therapy at 5 years, and contemporary hormonal contraception and the risk of breast cancer.
