Erdafitinib in patients with advanced solid tumours with FGFR alterations (RAGNAR): an international, single-arm, phase 2 study.

Background: FGFR alterations are reported across various malignancies and might act as oncogenic drivers in multiple histologies. Erdafitinib is an oral, selective pan-FGFR tyrosine kinase inhibitor with activity in FGFR-altered advanced urothelial carcinoma. We aimed to evaluate the safety and activity of erdafitinib in previously treated patients with FGFR-altered advanced solid tumours.

Efficacy and Safety of Nivolumab in Previously Treated Patients With Non-Small-cell Lung Cancer: Real World Experience in Argentina.

Background: Nivolumab was the first anti-programmed cell death 1 drug approved in Argentina for non-small-cell lung cancer treatment in the second-line setting.

Materials And Methods: The present study was a multicenter, observational, retrospective study of patients with progression to stage IV NSCLC during platinum-based chemotherapy who had received nivolumab monotherapy in a drug-expanded access program in Argentina.

Results: The data from 109 patients were assessed retrospectively for safety and clinical outcomes.

Immunotherapy at any line of treatment improves survival in patients with advanced metastatic non-small cell lung cancer (NSCLC) compared with chemotherapy (Quijote-CLICaP).

Background: To compare survival outcomes of patients with advanced or metastatic non-small cell lung cancer (NSCLC) who received immunotherapy as first-, second- or beyond line, versus matched patients receiving standard chemotherapy with special characterization of hyperprogressors.

Methods: A retrospective cohort study of 296 patients with unresectable/metastatic NSCLC treated with either, first-, second-, third- or fourth-line of immunotherapy was conducted. A matched comparison with a historical cohort of first-line chemotherapy and a random forest tree analysis to characterize hyperprogressors was conducted.

Use of Machine-Learning Algorithms in Intensified Preoperative Therapy of Pancreatic Cancer to Predict Individual Risk of Relapse.

Background: Although surgical resection is the only potentially curative treatment for pancreatic cancer (PC), long-term outcomes of this treatment remain poor. The aim of this study is to describe the feasibility of a neoadjuvant treatment with induction polychemotherapy (IPCT) followed by chemoradiation (CRT) in resectable PC, and to develop a machine-learning algorithm to predict risk of relapse.

Methods: Forty patients with resectable PC treated in our institution with IPCT (based on mFOLFOXIRI, GEMOX or GEMOXEL) followed by CRT (50 Gy and concurrent Capecitabine) were retrospectively analyzed.

Study of circulating microRNA-125b levels in serum exosomes in advanced melanoma.

Context: Malignant melanoma is an aggressive tumor that produces exosomes, which contain microRNAs (miRNAs) that could be of utility in following tumoral cell dysregulation. MicroR-125b is a miRNA whose down-regulation seems to be implicated in melanoma progression.

Objective: To analyze miR-125b levels in serum, and in exosomes obtained from serum, from patients with advanced melanoma.

Relevance of MIA and S100 serum tumor markers to monitor BRAF inhibitor therapy in metastatic melanoma patients.

BRAF V600 mutation has been reported in more than 50% of melanoma cases and its presence predicts clinical activity of BRAF inhibitors (iBRAF). We evaluated the role of MIA, S100 and LDH to monitor iBRAF efficiency in advanced melanoma patients presenting BRAF V600 mutations. This was a prospective study of melanoma patients harboring the BRAF V600 mutation and treated with iBRAF within a clinical trial (dabrafenib) or as part of an expanded access program (vemurafenib).

Neurological and cytological response as potential early predictors of time-to-progression and overall survival in patients with leptomeningeal carcinomatosis treated with intrathecal liposomal cytarabine: a retrospective cohort study.

Interesting neurological and cytological response rates after intrathecal (i.t) liposomal cytarabine have been observed in patients with leptomeningeal carcinomatosis (LMC) from solid tumors. However, the potential use of those responses as early predictors of time-to-progression (TTP) and overall survival (OS) is unexplored.

Safety and efficacy of maintenance therapy with a nonspecific cytochrome P17 inhibitor (CYP17i) after response/stabilization to docetaxel in metastatic castration-resistant prostate cancer.

Background: Frontline treatment of metastatic castration-resistant prostate cancer (mCRPC) consists of docetaxel-based chemotherapy. The median time to progression (TTP) from chemotherapy initiation is 6 to 8 months. Ketoconazole, a nonspecific cytochrome P17 inhibitor (CYP17i), blocks adrenal androgen synthesis.

Clinical management of small-cell carcinoma of the urinary tract: a 10-year single-center's experience.

Background: Small-cell carcinoma (SCC) comprises 1% of primary bladder tumors and approximately 2% of prostate neoplasms. Metastatic disease at diagnosis is common, and survival outcomes are extremely poor. There is controversy about the ideal clinical management of these patients.
