- Induction Chemotherapy for Locally Advanced Esophageal Cancer(2020) HARADA, Guilherme; BONADIO, Renata Rodrigues da Cunha Colombo; ARAUJO, Frederico Cantarino Cordeiro de; VICTOR, Carolina Ribeiro; SALLUM, Rubens Antonio Aissar; RIBEIRO JUNIOR, Ulysses; CECCONELLO, Ivan; TAKEDA, Flavio Roberto; CASTRIA, Tiago Biachi deBackground Concurrent chemoradiotherapy followed by surgery is the standard treatment for locally advanced esophageal cancer (EC), and the role of induction chemotherapy (IC) remains unclear. We aimed to study if the addition of IC to standard treatment increases the rate of pathologic complete response (pCR). Methods We assembled a retrospective analysis of patients (pts) diagnosed with locally advanced EC and treated with preoperative chemoradiotherapy followed by esophagectomy (CRT+S), preceded or not by IC, between 2009 and 2017. Patients' characteristics, tumor variables, and treatment outcomes were evaluated. The Kaplan-Meier method was used to estimate overall survival and the Cox proportional hazard model to evaluate prognostic factors. Results One hundred and three patients were studied, with a median age of 62 years (range 37-84). Seventy-five patients (73%) were male, 67 (65%) had squamous cell carcinoma, and 31 (30%) had adenocarcinoma. Forty-three patients (41.7%) received IC followed by CRT+S (IC+CRT+S). The most frequent IC consisted of paclitaxel and platinum chemotherapy (90%), and the median number of cycles was 2. All patients received CRT+S. Concurrent chemotherapy was a combination of paclitaxel and platinum in 94 patients (91%). There was no statistically significant difference in pCR between the IC group and the standard CRT+S group. The pCR was 41.9% and 46.7% in the IC+CRT+S and CRT+S groups (p = 0.628), respectively. In the multivariate analysis, pCR was an independent prognostic factor for time to treatment failure (TTF) (HR 0.35, p = 0.021), but not for overall survival (OS) (p = 0.863). The factor that significantly affected OS in the multivariate analysis was positive lymph node (HR 5.9, 95%, p = 0.026). Conclusions Our data suggest that the addition of IC to standard CRT + S does not increase the pCR rate in locally advanced EC. No difference in OS was observed between pts. that received or not IC. Regardless of the treatment received, pts. achieving a pCR presented improved TTF.
- Effectiveness and toxicity of adjuvant chemotherapy in patients with non-small cell lung cancer(2021) HARADA, Guilherme; NEFFA, Maria Fernanda Batistuzzo Vicentini; BONADIO, Renata Colombo; MENDOZA, Elizabeth Zambrano; CAPARICA, Rafael; LAURICELLA, Leticia Leone; TAKAGAKI, Teresa Yae; ROITBERG, Felipe Santa Rosa; TERRA, Ricardo Mingarini; JR, Gilberto De CastroObjective: Adjuvant chemotherapy (AC) improves survival of patients with resected non-small cell lung cancer (NSCLC). However, the cisplatin-vinorelbine regimen has been associated with a significant risk of clinically relevant toxicity. We sought to evaluate the effectiveness, safety, and feasibility of AC for NSCLC patients in a real-world setting. Methods: This was a single-center, retrospective cohort study of patients with stage I-III NSCLC undergoing surgery with curative intent between 2009 and 2018. AC was administered at the discretion of physicians. The patients were divided into two groups: AC group and no AC (control) group. Study outcomes included overall survival (OS) and recurrence-free survival (RFS), as well as the safety profile and feasibility of the cisplatin-vinorelbine regimen in a real-world setting. Results: The study involved 231 patients, 80 of whom received AC. Of those, 55 patients received the cisplatin- vinorelbine regimen. Survival analyses stratified by tumor stage showed that patients with stage II NSCLC in the AC group had better RFS (p = 0.036) and OS (p = 0.017) than did those in the no AC group. Among patients with stage III NSCLC in the AC group, RFS was better (p < 0.001) and there was a trend toward improved OS (p = 0.060) in comparison with controls. Of those who received the cisplatin- vinorelbine regimen, 29% had grade 3-4 febrile neutropenia, and 9% died of toxicity. Conclusions: These results support the benefit of AC for NSCLC patients in a real-world setting. However, because the cisplatin-vinorelbine regimen was associated with alarming rates of toxicity, more effective and less toxic alternatives should be investigated.
- US Food and Drug Administration anticancer drug approval trends from 2016 to 2018 for lung, colorectal, breast, and prostate cancer(2020) RIBEIRO, Tatiane Bomfim; RIBEIRO, Adalton; RODRIGUES, Luiza de Oliveira; HARADA, Guilherme; NOBRE, Moacyr Roberto CuceObjective This paper aims to describe the clinical and regulatory aspects of new drugs and indications that were approved for lung, breast, prostate, and colorectal cancer, from 2016 to 2018, in order to provide health technology assessment trends in oncology. Methods Data were collected from the US Food and Drug Administration (FDA) online database for new medications and indications approved for the above-mentioned types of cancer. Data regarding clinical study characteristics and regulatory information were collected. Results From 2016 to 2018, 53 percent of the FDA approvals of new drugs and indications for the most incident cancers were for oral protein kinase inhibitor monotherapy for advanced lung cancer. Since 2018, four drugs were approved as tumor-agnostic therapies. A biomarker was included in 72 percent of indications, and 58 percent of approvals were for targeted therapies, potentially heralding an end to research into conventional cytotoxic agents. A special designation for faster approval was granted in 78 percent of new approvals. The majority of the studies were open label randomized controlled trials (RCTs) (44 percent), followed by blind RCTs, single-arm clinical trials, and cohort studies. Only 14 percent of studies used overall survival as the primary end point; the vast majority used surrogate end points, and did not use patient-important outcomes. Three biosimilars were approved in the period. Conclusion Advanced lung cancer therapy, mainly targeted drugs, accounted for 53 percent of approvals. Special designations for faster approval were used in 78 percent of FDA approvals, and four drugs were approved for tumor-agnostic treatment-a new form of approval.

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
