    Background 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.

    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 Cuce
    Objective 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.
