ABSTRACT

Abstract Complete hydatidiform mole (CHM) is a rare type of pregnancy, in which 15 to 20% of the cases may develop into gestational trophoblastic neoplasia (GTN). The diagnostic of GTN must be done as early as possible through weekly surveillance of serum hCG after uterine evacuation.We report the case of 23-year-old primigravida, with CHM but without surveillance of hCG after uterine evacuation. Two months later, the patient presented to the emergency with vaginal bleeding and was referred to the Centro de Doenças Trofoblásticas do Hospital São Paulo. She was diagnosed with high risk GTN stage/score III:7 as per The International Federation of Gynecology and Obstetrics/World Health Organization (FIGO/WHO). The sonographic examination revealed enlarged uterus with a heterogeneous mass constituted of multiple large vessels invading and causing disarrangement of the myometrium. The patient evolved with progressive worsening of vaginal bleeding after chemotherapy with etoposide, methotrexate, actinomycin D, cyclophosphamide and vincristine (EMA-CO) regimen. She underwent blood transfusion and embolization of uterine arteries due to severe vaginal hemorrhage episodes, with complete control of bleeding. The hCG reached a negative value after the third cycle, and there was a complete regression of the anomalous vascularization of the uterus as well as full recovery of the uterine anatomy. The treatment in a reference center was essential for the appropriate management, especially regarding the uterine arteries embolization trough percutaneous femoral


Resumo Mola hidatiforme completa (MHC) é um tipo raro de gravidez, na qual 15 a 20% dos casos podem desenvolver neoplasia trofoblástica gestacional (NTG). O diagnóstico de NTG deve ser feito o mais cedo possível, pelo monitoramento semanal do hCG sérico após esvaziamento uterino. Relatamos o caso de uma paciente primigesta, de 23 anos de idade, com MHC, sem vigilância de hCG após esvaziamento uterino. Dois meses depois, a paciente compareceu na emergência com sangramento vaginal, sendo encaminhada ao Centro de Doenças Trofoblásticas do Hospital São Paulo, onde foi diagnosticada com NTG de alto risco, estádio e score de risco III:7 de acordo com a The International Federation of Gynecology and Obstetrics/Organização Mundial de Saúde (FIGO/OMS). O exame ultrassonográfico revelou útero aumentado com uma massa heterogênea constituída pormúltiplos vasos volumosos invadindo e desestruturando o miométrio. A paciente evoluiu com piora progressiva do sangramento vaginal após quimioterapia com o regime etoposide, methotrexate, actinomycin D, cyclophosphamide and vincristine (EMA-CO). Ela foi submetida a transfusão de sangue e embolização das artérias uterinas devido aos episódios graves de hemorragia vaginal, com completo controle do sangramento. O hCG atingiu valor negativo após o terceiro ciclo, havendo regressão completa da vascularização uterina anômala, assim como recuperação da anatomia uterina. O tratamento em um centro de referência permitiu o manejo adequado, principalmente no que se refere à embolização das artérias uterinas através da punção percutânea da artéria femoral, que foi crucial para evitar a histerectomia, permitindo a cura da NTG e a manutenção da vida reprodutiva.

ABSTRACT

OBJECTIVE@#To investigate the clinical efficacy and prognosis of patients with multiple myeloma (MM) treated by long-term maintenance lenalidomide treatment.@*METHODS@#A total of 97 patients diagnosed as MM in the Department of Hematology of First Affiliated Hospital of Guangzhou University of Chinese Medicine from 2012 to 2019 were selected, and the basic clinical characteristics and laboratory indicators of the patients were tested and evaluated. After long-term maintenance lenalidomide treatment for patients with MM, the short-term and long-term clinical efficacy and the incidence of adverse reactions were evaluated, and factors affecting the prognosis of the patients were analyzed.@*RESULTS@#Before maintenance treatment, 47.42% of the patients (46/97) did not achieve complete remission (CR), among 52.58% (51/97) of CR patients, there were 20.62% of the patients showed minimal residual leukemia (MRD) negative. After lenalidomide maintenance treatment, the patients who did not achieve CR were reduced to 24.74% (24/97), among 75.26% (73/97) of the patients with CR, there were 47.42% of the patients showed MRD negative, the difference showed statistically significant (P<0.001). After maintenance treatment, the median pro-gression-free survival of the patients was 58 months, and the 5-year survival rate was 89.69%. The incidence of adverse reactions was 40.21% (39/97), including neutropenia (31/39, 79.49%), fatigue (21/39, 53.85%), thrombocytopenia (17/39, 43.59%) and gastrointestinal reaction (15/39, 38.46%) were the most common. The discontinuation rate was 24.74% (24/97), and the median time for discontinuation was 21 months. The main reasons for discontinuation were neutropenia (12/24, 50.00%) , thrombocytopenia (8/24, 33.33%) and gastrointestinal reactions accounted for 8.33% (2/24). Old age and positive MRD were the risk factors affecting the prognosis of the patients. The adjusted OR was 1.43 (95% CI 1.03-1.76, P=0.034) and 3.78 (95% CI 2.56-9.56, P=0.037), respectively.@*CONCLUSION@#The long-term maintenance lenalidomide treatment shows a good clinical effect on patients with MM, and MRD detection can assist the cilinical judge the prognosis of the patients. During maintenance treatment, the clinical symptoms, especially blood system damage of the patients should be take care, so as to avoid serious adverse reactions.

ABSTRACT

OBJECTIVE@#To explore the impact of induction treatment response on the prognosis of pediatric core binding factor-acute myeloid leukemia (CBF-AML).@*METHODS@#The result of induce reaction and survival data of 157 pediatric CBF-AML patients in our hospital from September 2008 to December 2018 were retrospectively analyzed.The survival rate of the patients with different degrees of morphological remission after induction chemotherapy was comparative analyzed.@*RESULTS@#Among the 157 children with CBF-AML, 113 (72.4%) patients achieved morphologic leukemia-free state (MLFS) after the first course of induction chemotherapy, 153 (98.1%) patients achieved MLFS after the second course of induction chemotherapy. The 5-year event-free survival (EFS) rate and 5-year overall survival (OS) rate of patients with non-remission (NR) status after the first course of induction of chemotherapy was significantly lower than the patients achieved MLFS and the patients achieved partial remission (PR). The 5-year EFS rate and 5-year OS rate of the patients with PR status after the second course of induction chemotherapy were lower than the patients achieved MLFS, but the difference was not statistically significant. Multivariable analyze showed that NR after the first course of induction chemotherapy and myeloid sarcoma were the independent risk factors affecting EFS of the patients. There were six patients with NR status after the first course of induction chemotherapy, in which all of them harbored t(8;21), three of them with sex chromosome deletion, two of them with myeloid sarcoma.@*CONCLUSION@#NR status after the first course of induction chemotherapy was the independent risk factor affecting EFS and OS of CBF-AML patients, it can be taken as an indicator for higher risk stratification. PR status after the first course of induction chemotherapy may not be used as a diagnostic criterion for primary drug resistance.

ABSTRACT

BACKGROUND@#With current chemotherapy treatment, >90% of survival has been obtained for Burkitt lymphoma (BL). In this study, the demographic characteristics and treatment outcomes are presented for 78 children in China with central nervous system-positive (CNS+) BL.@*METHODS@#This retrospective study consecutively enrolled 78 CNS+ BL patients in Beijing Children's Hospital (BCH) from 2007 to 2019 who received the BCH B-cell non-Hodgkin's lymphoma regimen (modified by French-American-British mature lymphoma B-cell 96 [FAB/LMB96] C1 arm ± rituximab). Clinical characteristics, methods of disease detection in the CNS, and outcomes were evaluated. Univariate and multivariate analyses were used to assess prognostic factors.@*RESULTS@#The median age of 65 boys and 13 girls at the time of diagnosis was 5.7 years (ranging from 1 to 14 years). Patients were followed up for a median time of 34 months (ranging from 1 to 72 months). Bone marrow invasion was found in 38 (48.7%) patients. There were 48 (61.5%), 44 (56.4%), and 25 (32%) patients with cranial nerve palsy, intracerebral mass (ICM), and para-meningeal extension, respectively. Abnormal cerebrospinal fluid (CSF) morphology and CSF immunophenotype appeared in 15 (19.2%) and 15 (19.2%) patients, respectively. There were 69 (88.5%) patients treated with chemotherapy combined with rituximab, and nine patients were treated solely with chemotherapy. Finally, five patients died of treatment-related infection, recurrence occurred for 13, and one developed a second tumor. The 3-year overall survival and event-free survival rates were 78.9% ± 4.7% and 71.4% ± 6.0%, respectively. Treatment with chemotherapy only, ICM positivity, and >4 organs involved at diagnosis were independent risk factors.@*CONCLUSIONS@#Rituximab combined with a modified LMB96 regimen has greatly increased the efficacy of treatment for Chinese children with CNS+ BL, and with the continuous collection of outcome data, treatment-related complications are decreasing. For further verification, a large sample multicentre randomized controlled study should be performed to explore a treatment scheme for Chinese children with even greater efficacy.

ABSTRACT

The introduction of cyclin-dependent kinase (CDK) 4/6 inhibitors has revolutionized the clinical management paradigm of hormone receptor (HR) positive/human epidermal growth factor receptor (HER) 2 negative breast cancer. As of today, CDK 4/6 inhibitors including Palbociclib, Ribociclib, and Abemaciclib have been widely approved by regulatory agencies. Randomized clinical trials demonstrated that CDK 4/6 inhibitors in combination with an aromatase inhibitor (AI) or fulvestrant in the first-, second- or later-line setting for HR positive/HER2 negative locally advanced or metastatic breast cancer led to substantial reduction in the risk of disease progression or death. Adverse effects of treatment were manageable and as or better than expected in terms of patient satisfaction. Considering CDK4/6 inhibitors in combination with endocrine therapy being a novel approach in China clinical practice, the panel developed the consensus comprehensively describing the pharmacology properties, monitoring strategy during treatment and adverse events management, to facilitate greater understanding in Chinese oncologists of a whole new therapeutic class of drug, promote accuracy of clinical decision and help reach the ultimate goal of improving survival and quality of life of the target patient population.

ABSTRACT

Colorectal cancer is the second most common malignant tumor in China. The FOLFOXIRI regimen, which combines 5-fluorouracil/leucovorin, oxaliplatin, and irinotecan, is a high-intensity and highly effective chemotherapy regimen. However, the original regimen is poorly tolerated in Chinese patients. In order to promote the standardized and rational application of FOLFOXIRI regimen by clinicians in China, "

ABSTRACT

ABSTRACT Background Multimodal therapy with neoadjuvant chemoradiotherapy, followed by esophagectomy has offered better survival results, compared to isolated esophagectomy, in advanced esophageal cancer. In addition, patients who have a complete pathological response to neoadjuvant treatment presented greater overall survival and longer disease-free survival compared to those with incomplete response. Aim: To compare the results of overall survival and disease-free survival among patients with complete and incomplete response, submitted to neoadjuvant chemoradiotherapy, with two therapeutic regimens, followed by transhiatal esophagectomy. Methods: Retrospective study, approved by the Research Ethics Committee, analyzing the medical records of 56 patients with squamous cell carcinoma of the esophagus, divided into two groups, submitted to radiotherapy (5040 cGY) and chemotherapy (5-Fluorouracil + Cisplatin versus Paclitaxel + Carboplatin) neoadjuvants and subsequently to surgical treatment, in the period from 2005 to 2012, patients. Results The groups did not differ significantly in terms of gender, race, age, postoperative complications, disease-free survival and overall survival. The 5-year survival rate of patients with incomplete and complete response was 18.92% and 42.10%, respectively (p> 0.05). However, patients who received Paclitaxel + Carboplatin, had better complete pathological responses to neoadjuvant, compared to 5-Fluorouracil + Cisplatin (47.37% versus 21.62% - p = 0.0473, p <0.05). Conclusions There was no statistical difference in overall survival and disease-free survival for patients who had a complete pathological response to neoadjuvant. Patients submitted to the therapeutic regimen with Paclitaxel and Carboplastin, showed a significant difference with better complete pathological response and disease progression. New parameters are indicated to clarify the real value in survival, from the complete pathological response to neoadjuvant, in esophageal cancer.


RESUMO Racional: A terapia multimodal com quimioradioterapia neoadjuvantes, seguido de esofagectomia tem oferecido melhores resultados de sobrevida, em comparação à esofagectomia isolada, no câncer do esôfago avançado. Além disso, os doentes que apresentam resposta patológica completa ao tratamento neoadjuvante, têm evoluido com maior sobrevida global e maior sobrevida livre de doença em comparação aos que apresentam resposta incompleta. Objetivo: Comparar os resultados de sobrevida global e sobrevida livre de doença entre os doentes com resposta completa e incompleta, submetidos à quimioradioterapia neoadjuvante, com dois esquemas terapêuticos, seguidos de esofagectomia transhiatal. Métodos: Estudo retrospectivo, aprovado pelo Comitê de Ética em pesquisa, analisando os prontuários de 56 doentes, divididos em dois grupos de pacientes, submetidos a radioterapia (4400 a 5400 cGY) e quimioterapia (5-Fluorouracil+Cisplatina versus Paclitaxel+Carboplatina) neoadjuvantes e posteriormente a tratamento cirúrgico, no período de 2005 a 2012, portadores de carcinoma espinocelular do esôfago. Resultados: Os grupos não diferiram significativamente quanto ao gênero, raça, idade, complicações pós-operatórias, sobrevida livre de doença e sobrevida global. A sobrevida em 5 anos de doentes com resposta incompleta e completa foram, respectivamente, 18,92% e 42,10% (p>0,05). Entretanto, os doentes que receberam Paclitaxel+Carboplatina, tiveram melhores respostas patológicas completas à neoadjuvância, em comparação ao 5-Fluorouracil+Cisplatina (47,37% versus 21,62% - p=0,0473, p<0,05). Conclusões: Não houve diferença estatística na sobrevida global e na sobrevida livre de doença dos doentes que apresentaram resposta patológica completa à neoadjuvância. Os doentes submetidos ao esquema terapêutico com Paclitaxel e Carboplastina, mostraram diferença significativa com melhor resposta patológica completa e evolução da doença. Novos parâmetros são indicados para esclarecer o real valor na sobrevida, da resposta patológica completa à neoadjuvância, no câncer de esôfago.

ABSTRACT

OBJECTIVES To evaluate the results of radiotherapy (RT) for follicular lymphoma (FL) under different management scenarios. METHODS We retrospectively assessed consecutive patients with FL who had undergone irradiation between 2010 and 2018. All patients had biopsy-proven FL and were positron emission tomography-staged, although some (35.3%) were reassessed with computed tomography after treatment alone. Rituximab was only available to FL patients after 2016. RESULTS Thirty-four patients were selected, with a mean age at diagnosis of 61.6 years (34-89 years). The median follow-up duration was 49.4 months. Most patients were female (58.8%) and showed good performance on the Eastern Cooperative Oncology Group (ECOG) scale (ECOG 0-55.9%). The mean overall survival (OS) and progression-free survival were 48.7 and 33.6 months, respectively, with four deaths reported. OS rates at 2 and 3 years were 94.1% and 91.2%, respectively. Four patients showed transformation into aggressive lymphomas and underwent rituximab-based systemic treatment. Transformation-free survival was 47.8 months, and all patients with transformed disease were alive at assessment. Five patients had in-field relapse, all of them also relapsed elsewhere, and the mean relapse-free survival time was 40.3 months. No median end points were reached on assessment. CONCLUSION FL is an indolent disease. Our findings show good outcomes for patients treated with radiation, with a low transformation rate and excellent management of relapsed disease. RT is an important part of these results.

ABSTRACT

Although the first-line rituximab plus cyclophosphamide, doxorubicin, vincristine, and prednisone regimen (R-CHOP) substantially improved outcomes for patients with diffuse large B-cell lymphoma (DLBCL), 40% of the patients suffered from relapsed/refractory disease and had poor survival outcomes. The detailed mechanism underlying R-CHOP resistance has not been well defined. For this review, we conducted a thorough search for literature and clinical trials involving DLBCL resistance. We discussed DLBCL biology, epigenetics, and aberrant signaling of the B-cell receptor (BCR), phosphatidylinositol 3-kinase (PI3K)/Akt, nuclear factor kappa light chain enhancer of activated B-cells (NF-κB), and the Janus kinase (JAK)/signal transducer and activator of transcription 3 (STAT3) pathways as defining mechanisms of DLBCL heterogeneity and R-CHOP resistance. The cell of origin, double- or triple-hit lymphoma and double-protein-expression, clonal evolution, tumor microenvironment, and multi-drug resistance help to contextualize DLBCL resistance in an (epi)genetically and biologically comparative manner. With better understanding of the biological and molecular landscape of DLBCL, a more detailed classification system and tailored treatments will ideally become available to further improve the prognosis of DLBCL patients.

ABSTRACT

BACKGROUND@#Numerous studies have focused on lymphoma among patients infected with human immunodeficiency virus (HIV). However, little is known about the treatment options and survival rate of lymphoma in the Chinese people living with HIV (PLHIV). Our study aimed to investigate the prognosis and compare outcome of dose-adjusted etoposide, prednisone, vincristine, cyclophosphamide, doxorubicin, and rituximab (DA-EPOCH-R) with standard cyclophosphamide, doxorubicin, vincristine, prednisone and rituximab(R-CHOP) as front line therapy for PLHIV with diffuse large B-cell lymphoma (DLBCL) receiving modern combined antiretroviral therapy (cART).@*METHODS@#A retrospective analysis evaluating PLHIV with DLBCL was performed in Shanghai Public Health Clinical Center from July 2012 to September 2019. The demographic and clinical data were collected, and overall survival (OS) and progression-free survival (PFS) analyses of patients receiving R-CHOP or DA-EPOCH-R therapy were performed by Kaplan-Meier analysis. Additionally, a Cox multiple regression model was constructed to identify related factors for OS.@*RESULTS@#A total of 54 eligible patients were included in the final analysis with a median follow-up of 14 months (interquartile range [IQR]: 8-29 months). The proportion of high international prognostic index (IPI) patients was much larger in the DA-EPOCH-R group (n = 29) than that in the R-CHOP group (n = 25). The CD4 cell counts and HIV RNA levels were not significantly different between the two groups. The 2-year OS for all patients was 73%. However, OS was not significantly different between the two groups, with a 2-year OS rate of 78% for the DA-EPOCH-R group and 66% for the R-CHOP group. Only an IPI greater than 3 was associated with a decrease in OS, with a hazard ratio of 5.0. The occurrence of grade 3 and 4 adverse events of chemotherapy was not significantly different between the two groups.@*CONCLUSIONS@#Outcomes of R-CHOP therapy do not differ from those of DA-EPOCH-R therapy. No HIV-related factors were found to be associated with the OS of PLHIV in the modern cART era.

ABSTRACT

OBJECTIVES: The outcomes of refractory and relapsed acute myeloid leukemia (AML) patients in developing countries are underreported, even though the similar classic regimens are widely used. METHODS: We conducted a retrospective comparison of "MEC" (mitoxantrone, etoposide, and cytarabine) and "FLAG-IDA" (fludarabine, cytarabine, idarubicin, and filgrastim) in adults with first relapse or refractory AML. RESULTS: In total, 60 patients were included, of which 28 patients received MEC and 32 received FLAG-IDA. A complete response (CR) rate of 48.3% was observed. Of the included patients, 16 (27%) died before undergoing bone marrow assessment. No statiscally significant difference in CR rate was found between the two protocols (p=0.447). The median survival in the total cohort was 4 months, with a 3-year overall survival (OS) rate of 9.7%. In a multivariable model including age, fms-like tyrosine kinase 3 (FLT3) status, and stem-cell transplantation (SCT), only the last two indicators remained significant: FLT3-ITD mutation (hazard ratio [HR]=4.6, p<0.001) and SCT (HR=0.43, p=0.01). CONCLUSION: In our analysis, there were no significant differences between the chosen regimens. High rates of early toxicity were found, emphasizing the role of supportive care and judicious selection of patients who are eligible for intensive salvage therapy in this setting. The FLT3-ITD mutation and SCT remained significant factors for survival in our study, in line with the results of previous studies.

ABSTRACT

SUMMARY AIM To examine the relationship between treatment response and hypoxia-inducible factor-1 alpha (HIF-1α) levels in patients with locally advanced non-small cell lung cancer (NSCLC) who received chemoradiotherapy (CRT). METHODS Eighty patients with NSCLC were included in the study and treated at Acibadem Mehmet Ali Aydınlar University Medical Faculty. HIF-1 α levels were measured before and after CRT by the enzyme-linked immunosorbent assay (ELISA) method. RESULTS Patients' stages were as follows; stage IIIA (65%) and stage IIIB (35%). Squamous histology was 45%, adenocarcinoma was 44%, and others were 11%. Chemotherapy and radiotherapy were given concurrently to 80 patients. Forty-five (56%) patients received cisplatin-based chemotherapy, and 35 (44%) received carboplatin-based chemotherapy. Serum HIF-1α levels (42.90 ± 10.55 pg/mL) after CRT were significantly lower than the pretreatment levels (63.10 ± 10.22 pg/mL, p<0.001) in patients with locally advanced NSCLC. CONCLUSION The results of this study revealed that serum HIF-1α levels decreased after CRT. Decrease of HIF-1α levels after the initiation of CRT may be useful for predicting the efficacy of CRT.


RESUMO OBJETIVO Examinar a relação entre a resposta ao tratamento e os níveis de fator 1 induzida por hipóxia (HIF-1α) em pacientes com câncer de pulmão de células não pequenas localmente avançado (NSCLC) que receberam quimiorradioterapia (CRT). MÉTODO Oitenta pacientes com NSCLC foram incluídos no estudo e foram tratados na Faculdade de Medicina da Acibadem Mehmet Ali Aydınlar University. O nível de HIF-1α foi medido antes e depois da TRC pelo método de ensaio imunoenzimático (ELISA). RESULTADOS Os estágios dos pacientes foram os seguintes; estágio IIIA (65%) e estágio IIIB (35%). A histologia escamosa foi de 45%, o adenocarcinoma de 44% e o outro de 11%. Quimioterapia e radioterapia foram dadas simultaneamente a 80 pacientes. Quarenta e cinco (56%) pacientes receberam quimioterapia à base de cisplatina e 35 (44%) receberam quimioterapia à base de carboplatina. Os níveis séricos de HIF-1α (42,90 ± 10,55 pg / mL) após a TRC foram significativamente menores do que os níveis pré-tratamento (63,10 ± 10,22 pg / mL, p <0,001) em pacientes com NSCLC localmente avançado. CONCLUSÃO Os resultados deste estudo revelaram que os níveis séricos de HIF-1α diminuíram após a TRC. A diminuição dos níveis de HIF-1α após o início da TRC pode ser útil para prever a eficácia da TRC.

Material and Methods: Analysis of a database held by the Chilean Ministry of Health, including all patients treated at accredited cancer treatment centers. Results: Data for 915 patients, median age 35 years (range 15-86 years) and followed for a median of 97 months (range 1-347 months) were analyzed. Forty-one percent had localized disease. Overall survival at five years for localized and advanced stages was 92% and 74%, respectively. The figures for progression free survival were 87% and 64%, respectively. Patients with relapse who received autologous stem cell transplantation (ASCT) had a five year overall survival of 92%, compared to 64% among those who did not undergo this procedure (p < 0.01). The Guarantees in Health Program set up by the Ministry of Health, was associated with earlier stage disease at diagnosis. Conclusions: The ABVD regimen achieves high rates of cure in localized stages of the disease but the results in advanced stages are not optimal. ASCT significantly improves survival in patients with relapse. The Guarantees in Health Program is associated with earlier diagnosis of the disease.

ABSTRACT

Background: Waldenström macroglobulinemia (WM) is an uncommon indolent B-cell lymphoma, due to the proliferation of lymphoplasmacytic cells, and secretion of a monoclonal IgM protein. Aim: To evaluate the clinical characteristics, management and results of treatment of patients with WM at a public hospital in Chile. Patients and Methods: Review of medical records of 31 patients aged 43 to 85 years (16 males) with WM diagnosed between 2002 and 2017. Clinical features and survival were recorded. Results: All patients had bone marrow compromise, and 31%, extranodal involvement. According to the International Prognostic Score System for WM (IPSSWM) 16, 58 and 26% were at low, intermediate and high risk, respectively. Twenty-five patients (81%) were treated, 32% with plasmapheresis and 36% with rituximab. Four cases (16%) achieved complete remission. Median follow up was 35 months (range 6-159). Estimated overall survival (OS) at 5 and 10 years was 74% and 53%, respectively. According to IPSSWM, the estimated five-year OS was 80, 92 and 39%, for low, intermediate and high-risk patients, respectively. Conclusions: OS was similar to that reported abroad, except for low risk patients, probably due to the low number of cases and short follow up. An improved survival should be expected with the routine use of immunochemotherapy.

ABSTRACT

Patients transplanted from solid organs have an increased risk of cancer, especially lymphomas. Lymphomas correspond to 4 to 5% of malignant neoplasms in the general population and in solid organ transplant patients it reaches an incidence of 21%. The incidence of non-Hodgkin lymphomas is 10 times higher than in the non-transplanted population. We report the case of a 68-year-old man with a kidney transplant who 6 years after transplantation, developed a non-Hodgkin diffuse large cells B lymphoma with lymph node and pulmonary involvement, with markers of very poor prognosis (triple MYC expressor, BCL2 and BCL6). and its evolution with chemotherapy with DA R EPOCH.

ABSTRACT

ABSTRACT Objective To evaluate the cost-effectiveness of the addition of chemotherapy or abiraterone to androgen deprivation. Methods We developed an analytical model to determine the cost-effectiveness of the addition of docetaxel or abiraterone versus androgen deprivation therapy alone. Direct and indirect costs were included in the model. The effects were expressed in Quality-Adjusted Life Years adjusted for side effects. Results Compared to androgen deprivation therapy alone, the addition of chemotherapy and of abiraterone generated 0.492 and 0.999, respectively, in Quality-Adjusted Life Years. Abiraterone led to a Quality-Adjusted Life Years gain of 0.506 compared to docetaxel. The incremental costs per Quality-Adjusted Life Years were R$ 133.649,22 for docetaxel, R$ 330.828,70 for abiraterone and R$ 571.379,42 for abiraterone compared to docetaxel, respectively. Conclusion The addition of chemotherapy to androgen deprivation therapy is more cost-effective than the addition of abiraterone to androgen deprivation therapy. However, discounts on abiraterone cost might improve cost-effectiveness.


RESUMO Objetivo Avaliar a relação custo-efetividade da adição de quimioterapia ou abiraterona à terapia de privação hormonal. Métodos Um modelo analítico foi desenvolvido para determinar a relação custo-efetividade da adição de docetaxel ou abiraterona comparada à terapia de privação hormonal isolada. Custos diretos e indiretos foram incluídos no modelo. Os efeitos foram expressos em Anos de Vida Ajustados para Qualidade corrigidos pelos efeitos colaterais de cada terapia. Resultados A adição de quimioterapia e de abiraterona à terapia de privação hormonal aumentou os Anos de Vida Ajustados para Qualidade em 0,492 e 0,999, respectivamente, em comparação à terapia de privação hormonal isolada. A abiraterona promoveu ganho de Anos de Vida Ajustados para Qualidade de 0,506 em relação ao docetaxel. O custo incremental por Anos de Vida Ajustados para Qualidade foi R$ 133.649,22 para o docetaxel, R$ 330.828,70 para a abiraterona e R$ 571.379,42 para a abiraterona comparada ao docetaxel. Conclusão A adição de quimioterapia à terapia de privação hormonal é mais custo-efetiva que a adição de abiraterona à terapia de privação hormonal. Contudo, descontos no custo da abiraterona poderiam tornar esse tratamento mais custo-efetivo.

ABSTRACT

ABSTRACT Objective: To comprehensively analyze the perception of women with breast cancer on the experience of undergoing chemotherapy. Method: This was a qualitative, descriptive, phenomenological study, supported by the Merleau-Ponty philosophy. It was conducted in a chemotherapy outpatient clinic with 20 participants who completed a phenomenological interview. Results: The phenomenological data analysis demonstrated that the perception of women about the experience of chemotherapy is about change, not only of the physical body, but of their identity, and that it considers existential aspects. Three categories emerged from the experience of alopecia, fatigue, and spirituality, respectively: the body itself, the current and habitual body, and transcendence. Final considerations: Bodily changes, and the existential implications perceived by the women in this study, analyzed from the Merleau-Ponty perspective, makes it possible to consider body concept, and provides support for humanized care based on singularity and the socio-cultural context.


RESUMEN Objetivo: Analizar exhaustivamente la percepción de las mujeres con cáncer de mama sobre la experiencia de la quimioterapia. Método: Este fue un estudio cualitativo, descriptivo, fenomenológico, respaldado por la filosofía Merleau-Ponty realizada en una clínica ambulatoria de quimioterapia con 20 participantes que se sometieron a una entrevista fenomenológica. Resultados: El análisis fenomenológico de los datos demostró que la percepción de las mujeres sobre la experiencia de la quimioterapia tiene que ver con el cambio, no solo del cuerpo físico, sino de la identidad y el alcance de los aspectos existenciales. De la alopecia, fatiga y espiritualidad emergieron tres categorías respectivamente: el cuerpo mismo, el cuerpo actual y habitual y la trascendencia. Consideraciones finales: El cambio del cuerpo y sus implicaciones existenciales percibidas por las mujeres en este estudio, y analizadas bajo la perspectiva de Merleau-Pontyana, permiten cubrir la concepción del cuerpo y proporcionar subsidios para el cuidado humanizado basado en la singularidad y el contexto sociocultural.


RESUMO Objetivo: Analisar compreensivamente a percepção de mulheres com câncer de mama sobre a vivência da quimioterapia. Método: Trata-se de um estudo de natureza qualitativa, descritivo, do tipo fenomenológico, respaldado na filosofia de Merleau-Ponty. Foi realizado em um ambulatório de quimioterapia e contou com 20 participantes que foram submetidas a entrevista fenomenológica. Resultados: A partir da análise fenomenológica dos dados, compreendeu-se que a percepção das mulheres sobre a vivência da quimioterapia é de mudança, não só de corpo físico, mas de identidade e alcança aspectos existenciais. A partir da vivência da alopecia, fadiga e espiritualidade emergiram três categorias respectivamente: o corpo próprio, o corpo atual e habitual e a transcendência. Considerações finais: A mudança de corpo e suas implicações existenciais percebidas pelas mulheres no estudo, analisadas sob a ótica Merleau-Pontyana, possibilitam abranger a concepção de corpo, fornecendo subsídios para o cuidado humanizado a partir da singularidade e do contexto sociocultural.

ABSTRACT

RESUMO Objetivo: analisar a expressão do Fator de Crescimento do Endotélio Vascular (VEGF), seu receptor (VEGFR-2), idade e tipo histológico de carcinomas avançados de colo uterino com relação à resposta clínica à quimioterapia neoadjuvante. Métodos: foram incluídas 40 pacientes com diagnóstico de carcinoma de colo uterino (IB2 e IVA), com biópsias prévias ao tratamento. Todas as pacientes foram submetidas à quimioterapia neoadjuvante e avaliadas quanto à resposta clínica e à expressão do VEGF. Considerou-se boa resposta clínica uma regressão tumoral total ou maior do que 50%. Resultados: em relação à resposta à quimioterapia, 18 pacientes (45%) apresentaram boa resposta e 22 (55%), má resposta. Quanto à expressão do VEGF, em 16 pacientes foi considerada positiva e em 24, negativa. Quando os casos foram analisados separadamente em relação à resposta à quimioterapia, somente a expressão positiva de VEGF foi associada à boa resposta clínica (p=0,0157). Conclusão: a expressão de VEGF mostrou ser isoladamente, um importante marcador de boa resposta ao tratamento quimioterápico neoadjuvante das pacientes com carcinoma avançado de colo uterino.


ABSTRACT Objective: to analyze the expression of Vascular Endothelial Growth Factor (VEGF), its receptor (VEGFR-2), age and histological type of advanced cervical carcinomas with respect to the clinical response to neoadjuvant chemotherapy. Methods: we studied 40 patients with cervical carcinoma (IB2 and IVA) diagnosed by biopsies prior to treatment. All patients underwent neoadjuvant chemotherapy and evaluation for clinical response and expression of VEGF. We considered a tumor regression greater than 50% as a good clinical response. Results: eighteen patients (45%) had good response to chemotherapy, and 22 (55%), poor response. VEGF expression was positive in 16 patients and negative in 24. When analyzed separately for response to chemotherapy, only the positive expression of VEGF was associated with good clinical response (p=0.0157). Conclusion: VEGF expression alone was an important marker of good response to neoadjuvant chemotherapy in patients with advanced carcinoma of the cervix.
