- Survival and consolidative radiotherapy in patients living with HIV and treated for diffuse large B-cell lymphoma(2020) CASIMIRO, Lucas Coelho; MAURO, Geovanne Pedro; MEDICI, Carolina Trindade Mello; WELTMAN, EduardoObjectives: Current guidelines tend to treat HIV positive (HIV+) patients as their seronegative counterparts with diffuse large B-cell lymphoma (DLBCL) but little is known about their radiotherapy responses differences. Patients and Methods: A retrospective cohort of all consecutive HIV+ DBCL patients treated with chemotherapy between 2004 and 2018 was assessed. All patients had biopsy-proven lymphomas. They were included if the proposed radical treatment was done without progression or death during chemotherapy and had at least 6 months of follow-up or were followed until death. Results: Fifty-three (53) patients were selected, with a median age at diagnosis of 41.39 years (20-65 years). Median follow-up of 35.16 months (1.4-178.7 months). Male patients accounted for 54.7% and most had a good performance in the ECOG scale at diagnoses (81.1% are ECOG 0-1). Median overall survival was not reached. Mean OS was 41.5 months with 16 deaths. Age had an impact on OS, with patients older than 60 years at more risk (p = 0.044), as did longtime use of HAART, with those that started antiretroviral therapy within the diagnose of the lymphoma at greatest risk (p = 0.044). RT did not have an impact on OS (p = 0.384) or PFS (p = 0.420), although survival curves show better OS in the radiotherapy group. Toxicities were rare, since none of the patients had grade 3 or superior toxicity. Conclusion: RT did not impact survival or progression in our limited sample, but a longer OS may occur after the first-year post RT. RT should be tested in prospective data in the HIV+ population with DLBCL.
- Results of consolidative radiotherapy for relapsed diffuse B-cell lymphoma(2023) MAURO, Geovanne Pedro; RIBEIRO NETO, Mario; CARVALHO, Heloisa de AndradeBackground: Recurrent diffuse large B-cell lymphoma (DLBCL) is a disease with high mortality. The standard of care involves autologous stem-cell transplantation (ASCT), which is not always feasible. We investigated the impact of radiotherapy as part of the salvage treatment for patients with relapsed disease. Materials and methods: Retrospective study of patients with recurrent DLBCL after chemotherapy and consolidative radiotherapy at a single institution. All patients were included if radiation was part of the first treatment. Results: Of 359 patients assessed between 2010 and 2017, 65 (18.1%) presented a recurrence, but only 62 received further treatment and were included in the study. Mean overall survival was 18.6 months since diagnosis and progression-free survival after first progression (PFS2) was 7.7 months. Patients were divided into two groups according to whether they did (24.8%) or did not (75.8%) receive radiation as part of their salvage treatment. Patients that did not receive R-CHOP (rituximab plus cyclophosphamide, doxorubicin hydrochloride, vincristine, and prednisone) in the first line were treated more with radiation in the second line (p = 0.02). Six patients with in-field relapse were re-irradiated. Only 4 patients received ASCT as part of their treatment for relapsed disease. There was no difference in outcomes. Conclusion: There is a place for radiotherapy in the treatment of relapsed DLBCL, particularly when patients do not receive ASCT. Radiotherapy is well-tolerated. More trials to assess the role of radiotherapy for these patients are needed.
- Radiotherapy for early and advanced stages Follicular Lymphoma(2021) MAURO, Geovanne Pedro; MEDICI, Carolina Trindade Mello; CASIMIRO, Lucas Coelho; WELTMAN, EduardoOBJECTIVES: 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.
- Curative treatment for stage IIIC2 cervical cancer: what to expect?(2023) MAURO, Geovanne Pedro; CALHEIROS, Vinicius de Aquino; VONSOWSKI, Matheus Sorgi; AVELAR, Talita; CARVALHO, Heloisa de AndradeBackground: Since the GOG125 study, treating radically patients with positive para-aortic lymph nodes has been a valid approach. Nevertheless, literature lacks data on how to better treat these patients since they are usually excluded from trials. In this study, we aimed to report the outcomes of patients with advanced cervical cancer and positive para-aortic lymph nodes (PAN) treated in a single tertiary/academic institution and try to identify variables that may impact survival. Materials and methods: We retrospectively reviewed patients with positive para-aortic lymph nodes treated in our institution. Demographic variables and treatment options were assessed and their impact on overall survival (OS), locorregional control, distant metastasis free survival, and para-aortic lymph node progression was analyzed. Results: We assessed 65 patients treated from April 2010 to May 2017. Median OS was 38.7 months. Median locorregional and para-aortic progression free survivals were not reached. Median distant metastasis progression-free survival was 64.3 months. Better ECOG performance status (p > 0.001), concurrent chemotherapy (p = 0.031), and brachytherapy (p = 0.02) were independently related to better overall survival. Conclusion: Patients with current stage IIIC2 cervix cancer may present long term survival. Treating positive PAN cervical cancer patients with concurrent chemoradiation including brachytherapy with curative intent should be standard. Poor PS and more advanced pelvic disease may represent a higher risk for worse outcomes. Distant metastases are still a challenge for disease control.
