    (2016) SEBASTIAO, Ana Morais; ROCHA, Lucila Soares da Silva; GIMENEZ, Rodrigo Darouche; BARROS, Laryssa Almeida Borges de; FUKUSHIMA, Julia Tizuko; SILVA, Samantha Cabral Severino da; MIRANDA, Vanessa da Costa; CAIRES, Inacelli Queiros de Souza; FREITAS, Daniela de; ABDO FILHO, Elias; DIZ, Maria Del Pilar Estevez
    Objective: To evaluate the results of treatment with cisplatin or carboplatin concomitant with radiotherapy (RT) in cases of locally advanced cervical cancer (CC). Methods: This study is a retrospective analysis of medical records of 184 patients with cervical cancer stage IIB-IVA who were treated at Instituto do Cancer do Estado de Sao Paulo from May 2008 to December 2012. All patients received complete pelvic region external-beam RT with weekly cisplatin (cis-RT, 40 mg/m(2); n = 159) or carboplatin (carbo-RT, AUC 2; n = 25), followed by high-dose-rate intracavitary brachytherapy (HDR-ICBT). Primary endpoint was progression free survival; secondary endpoints were overall survival and overall response rate, which includes complete and partial responses. Results: Five or more chemotherapy cycles were administered to 87.3% and 84% of the cis-RT- and carbo-RT- treated patients, respectively (p = 0.749). Estimated 3-years progression free survival was 59% in the cis-RT group vs 40% in the carbo-RT group (p = 0.249). Estimated 3-years overall survival was 70% in the cis-RT group vs 68% in the carbo-RT group (p = 0.298). Overall response rate (95.3% cis-RT vs 95.4% carbo-RT; p = 0.911) and grade >= 3 toxic effects (8.5% cis-RT vs 11.8% carbo-RT; p = 0.757) were similar. In multivariate analysis, only the overall response rate was a significant predictor of survival. Conclusions: Patients with advanced cervical cancer who are treated with carbo-RT have similar 3-years overall survival, progression free survival, overall response rate, and toxic effects when compared to cis-RT-treated patients. Carbo-RT may be an alternative treatment in patients that cannot receive cisplatin.

    Olaparib tablets as maintenance therapy in patients with platinum-sensitive relapsed ovarian cancer and a BRCA1/2 mutation (SOLO2/ENGOT-Ov21): a final analysis of a double-blind, randomised, placebo-controlled, phase 3 trial
    (2021) POVEDA, Andres; FLOQUET, Anne; LEDERMANN, Jonathan A.; ASHER, Rebecca; PENSON, Richard T.; OZA, Amit M.; KORACH, Jacob; HUZARSKI, Tomasz; PIGNATA, Sandro; FRIEDLANDER, Michael; BALDONI, Alessandra; PARK-SIMON, Tjoung-Won; TAMURA, Kenji; SONKE, Gabe S.; LISYANSKAYA, Alla; KIM, Jae-Hoon; FILHO, Elias Abdo; MILENKOVA, Tsveta; LOWE, Elizabeth S.; ROWE, Phil; VERGOTE, Ignace; PUJADE-LAURAINE, Eric
    Background Olaparib, a poly (ADP-ribose) polymerase (PARP) inhibitor, has previously been shown to extend progression-free survival versus placebo when given to patients with relapsed high-grade serous or endometrioid ovarian cancer who were platinum sensitive and who had a BRCA1 or BRCA2 (BRCA1/2) mutation, as part of the SOLO2/ENGOT-Ov21 trial. The aim of this final analysis is to investigate the effect of olaparib on overall survival. Methods This double-blind, randomised, placebo-controlled, phase 3 trial was done across 123 medical centres in 16 countries. Eligible patients were aged 18 years or older, had an Eastern Cooperative Oncology Group performance status at baseline of 0-1, had histologically confirmed, relapsed, high-grade serous or high-grade endometrioid ovarian cancer, including primary peritoneal or fallopian tube cancer, and had received two or more previous platinum regimens. Patients were randomly assigned (2:1) to receive olaparib tablets (300 mg in two 150 mg tablets twice daily) or matching placebo tablets using an interactive web or voice-response system. Stratification was by response to previous chemotherapy and length of platinum-free interval. Treatment assignment was masked to patients, treatment providers, and data assessors. The primary endpoint of progression-free survival has been reported previously. Overall survival was a key secondary endpoint and was analysed in all patients as randomly allocated. Safety was assessed in all patients who received at least one treatment dose. This trial is registered with ClinicalTrials.gov, NCT01874353, and is no longer recruiting patients. Findings Between Sept 3, 2013 and Nov 21, 2014, 295 patients were enrolled. Patients were randomly assigned to receive either olaparib (n=196 [66%]) or placebo (n=99 [34%]). One patient, randomised in error, did not receive olaparib. Median follow-up was 65middot7 months (IQR 63middot6-69middot3) with olaparib and 64middot5 months (63middot4-68middot7) with placebo. Median overall survival was 51middot7 months (95% CI 41middot5-59middot1) with olaparib and 38middot8 months (31middot4-48middot6) with placebo (hazard ratio 0middot74 [95% CI 0middot54-1middot00]; p=0middot054), unadjusted for the 38% of patients in the placebo group who received subsequent PARP inhibitor therapy. The most common grade 3 or worse treatment-emergent adverse event was anaemia (which occurred in 41 [21%] of 195 patients in the olaparib group and two [2%] of 99 patients in the placebo group). Serious treatment-emergent adverse events were reported in 50 (26%) of 195 patients receiving olaparib and eight (8%) of 99 patients receiving placebo. Treatment-emergent adverse events with a fatal outcome occurred in eight (4%) of the 195 patients receiving olaparib, six of which were judged to be treatment-related (attributed to myelodysplastic syndrome [n=3] and acute myeloid leukaemia [n=3]). Interpretation Olaparib provided a median overall survival benefit of 12middot9 months compared with placebo in patients with platinum-sensitive, relapsed ovarian cancer and a BRCA1/2 mutation. Although statistical significance was not reached, these findings are arguably clinically meaningful and support the use of maintenance olaparib in these patients.

    Neoadjuvant Chemotherapy With Cisplatin and Gemcitabine Followed by Chemoradiation Versus Chemoradiation for Locally Advanced Cervical Cancer: A Randomized Phase II Trial
    (2019) COSTA, Samantha Cabral S. da; BONADIO, Renata Colombo; GABRIELLI, Flavia Carolina G.; ARANHA, Andrea S.; GENTA, Maria Luiza N. Dias; MIRANDA, Vanessa C.; FREITAS, Daniela de; ABDO FILHO, Elias; FERREIRA, Patricia A. O.; MACHADO, Karime K.; SCARANTI, Mariana; CARVALHO, Heloisa de A.; ESTEVEZ-DIZ, Maria Del Pilar
    PURPOSE Although chemoradiation therapy (CRT) with cisplatin remains the standard treatment of patients with locally advanced cervical cancer (LACC), 40% of patients present with disease recurrence. Additional treatment strategies are required to improve outcomes. We conducted a trial to evaluate the efficacy and safety of neoadjuvant chemotherapy (NAC) with cisplatin and gemcitabine followed by CRT. METHODS In this phase II trial, patients with LACC (International Federation of Gynecology and Obstetrics stage IIB to IVA or with positive lymph nodes) were randomly assigned to three cycles of NAC with cisplatin and gemcitabine followed by standard CRT with weekly cisplatin plus pelvic radiotherapy or to standard CRT alone. The primary end point was 3-year progression-free survival (PFS). Secondary end points were response rate, 3-year locoregional control, 3-year overall survival (OS), safety, and quality of life. RESULTS From 107 patients enrolled in the trial, 55 were randomly assigned to the NAC arm and 52 to the CRT-alone arm. The majority of patients had squamous cell carcinoma (87.8%). After a median follow-up of 31.7 months, NAC was associated with an inferior PFS, with 3-year PFS rates of 40.9% v 60.4% in the CRT arm (hazard ratio, 1.84; 95% CI, 1.04 to 3.26; P = .033). NAC also was associated with a lower OS (3-year OS rate, 60.7% v 86.8%; hazard ratio, 2.79; 95% CI, 1.29 to 6.01; P = .006). After treatment completion, complete response rates were 56.3% in the NAC arm and 80.3% in the CRT arm (P = .008). Toxicities were similar in both arms, with the exception of hypomagnesemia and neuropathy being more common with NAC. CONCLUSION This study shows that the addition of NAC consisting of cisplatin and gemcitabine to standard CRT is not superior and is possibly inferior to CRT alone for the treatment of LACC.

    Adjuvant Carboplatin and Paclitaxel Chemotherapy Followed by Radiotherapy in High-Risk Endometrial Cancer: A Retrospective Analysis
    (2018) BONADIO, Renata Rodrigues da Cunha Colombo; AZEVEDO, Renata Gondim Meira Velame; HARADA, Guilherme; COSTA, Samantha Cabral Severino da; MIRANDA, Vanessa Costa; FREITAS, Daniela de; ABDO FILHO, Elias; FERREIRA, Patricia Alves de Oliveira; GABRIELLI, Flavia; DIZ, Maria del Pilar Estevez
    Purpose The best adjuvant treatment in high-risk endometrial cancer remains unclear. Although adjuvant chemotherapy seems to improve overall survival (OS) in locally advanced disease, the role of adding radiotherapy is not certain. We evaluated the outcomes of patients with high-risk endometrial cancer treated with adjuvant chemotherapy followed by radiotherapy. Patients and Methods We performed a retrospective analysis of patients with high-risk endometrial cancer (endometrioid histology stages III to IVA or carcinosarcoma, clear cell, or serous histology stages I to IVA) treated with adjuvant carboplatin and paclitaxel, followed by radiotherapy, from 2010 to 2017 at a Brazilian cancer center. The Kaplan-Meier method was used for survival analysis, and prognostic factors were analyzed using the Cox proportional hazards model. Results One hundred forty-six consecutive patients were evaluated. The OS rates were 86.2% at 3 years and 75.4% at 5 years. OS was significantly affected by pelvic lymphadenectomy (P = .001) and positive peritoneal cytology (P < .001). Three- and 5-year disease-free survival (DFS) rates were 78.3% and 69.5%, respectively. The initial site of recurrence was limited to the pelvis in 4.1% of patients, within the abdomen in 1.3%, and extra-abdominal in 11.6%. Patients with grade 1 or 2 endometrioid carcinoma had better prognosis than patients with endometrioid carcinoma grade 3 or nonendometrioid histology (3-year DFS, 93.67% v 68.5%, respectively; P = .0017). Conclusion Adjuvant carboplatin and paclitaxel, followed by radiotherapy, is effective in high-risk endometrial cancer and associated with low rates of pelvic recurrence, which might be explained by the addition of radiotherapy. The high-risk group is heterogeneous, and the benefit of adjuvant treatment in patients with grade 1 or 2 endometrioid carcinoma is less clear. (C) 2018 by American Society of Clinical Oncology
