ENDOCRINE SIDE EFFECTS OF ANTI-CANCER DRUGS: Effects of anti-cancer targeted therapies on lipid and glucose metabolism

2014

During the past years, targeted therapies for cancer have been developed using drugs that have significant metabolic consequences. Among them, the mammalian target of rapamycin (mTOR) inhibitors and, to a much lesser extent, the tyrosine kinase inhibitors (TKIs) are involved. mTOR plays a key role in the regulation of cell growth as well as lipid and glucose metabolism. Treatment with mTOR inhibitors is associated with a significant increase in plasma triglycerides and LDL cholesterol. mTOR inhibitors seem to increase plasma triglycerides by reducing the activity of the lipoprotein lipase which is in charge of the catabolism of triglyceride-rich lipoproteins. The increase in LDL cholesterol…

2013

4031 Background: The novel somatostatin analog (SSA) pasireotide has a broader binding profile than currently available SSA (octreotide and lanreotide). Results from a phase III study (NCT00690430) of pasireotide LAR (P) vs octreotide LAR (O) in patients (pts) with NET and disease-related symptoms uncontrolled by the maximum approved dose of available SSA are shown. Methods: Pts (N=110) were randomized and stratified by predominant symptom at baseline (diarrhea [D], flushing [F], or D+F) 1:1 to P (60 mg IM) or O (40 mg IM) q28d. Primary objective was symptom response at month (M) 6. Secondary objectives included tumor response and safety. Progression-free survival (PFS) was an exploratory …

Everolimus after hepatic arterial embolisation therapy of metastases from gastrointestinal neuroendocrine tumours: The FFCD 1104-EVACEL-GTE phase II …

2019

Abstract Background Hepatic arterial embolisation therapy (HAET) is a treatment of liver metastases of gastrointestinal neuroendocrine tumours (GI-NETs). HAET increases circulating vascular endothelial growth factor levels. Everolimus is a treatment in NETs that may have antiangiogenic activity. Methods This phase II study was conducted in patients with predominant and progressive liver metastases from GI-NETs. Everolimus was initiated 7–30 days after HAET. The hypothesis was that everolimus after HAET would increase hepatic progression-free survival (hPFS) rate at 24 months from 35% to 50%. Results Among the 74 patients included, 88% had small-bowel primary tumour, 43% had grade I and 57% …

FOLFIRINEC: a randomized phase II trial of mFOLFIRINOX vs platinum-etoposide for metastatic neuroendocrine carcinoma of gastroenteropancreatic or unk…

2021

Abstract Background Poorly differentiated neuroendocrine carcinomas (NEC) are rare diseases with a poor prognosis. Platinum-etoposide (PE) has been the recommended first-line treatment for decades. FOLFIRINEC (NCT04325425) is a national multicenter randomized phase II study which aims to challenge this standard regimen. Methods The primary objective is to compare the median progression-free survival (PFS) under mFOLFIRINOX versus PE. The secondary objectives are to evaluate the objective response rates (ORR), median overall survival (OS), safety and quality of life. The associated real-time translational study will establish a molecular profile for each patient enrolled. Main inclusion crit…

Risk factors for Coronavirus Disease 2019 (COVID-19) severity and mortality among solid cancer patients and impact of the disease on anticancer treat…

2020

Background Cancer patients are thought to have an increased risk of developing severe Coronavirus Disease 2019 (COVID-19) infection and of dying from the disease. In this work, predictive factors for COVID-19 severity and mortality in cancer patients were investigated. Patients and Methods In this large nationwide retro-prospective cohort study, we collected data on patients with solid tumours and COVID-19 diagnosed between March 1 and June 11, 2020. The primary endpoint was all-cause mortality and COVID-19 severity, defined as admission to an intensive care unit (ICU) and/or mechanical ventilation and/or death, was one of the secondary endpoints. Results From April 4 to June 11, 2020, 1289…

2020

Abstract Introduction This document is a summary of the French Intergroup guidelines regarding the management of digestive neuroendocrine neoplasms (NEN) published in February 2020 ( www.tncd.org ). Methods All French medical societies involved in the management of NEN took part in this work. Recommendations were graded into four categories (A, B, C or D), according to the level of evidence found in the literature until May 2019. Results The management of NEN is challenging because of their heterogeneity and the increasing complexity of diagnostic and therapeutic procedures. Pathological analysis is required for their diagnostic and prognostic characterization, which mainly relies on differ…
