Purpose: Available tools to measure fatigue and health-related quality of life (HRQoL) in cancer patients are often difficult to use in clinical practice. The fatigue visual analogue scale (VAS) provides a simple method to assess fatigue. This study evaluated the correlation between HRQoL and fatigue perceived by cancer patients undergoing chemotherapy.

Introduction: Non-inferiority of NEPA (fixed combination of NK receptor antagonist (RA), netupitant, and 5-HT RA, palonosetron) versus an aprepitant regimen was previously shown in a pragmatic study in patients receiving anthracycline cyclophosphamide (AC) and non-AC moderately emetogenic chemotherapy (MEC). In the MEC group a numerically higher complete response (CR: no emesis, no rescue) rate was seen for NEPA during the overall 0-120 h phase (NEPA 76.1% vs.

Patients with resectable stage IIIA - N2 lung cancer represent a very heterogeneous population with variable risks of postoperative recurrence depending on the type of N2 involvement (unisite N2, multisite N2, bulky N2, extra-capsular rupture, incomplete resection…). This heterogeneity associated with the difficulty of carrying out prospective randomized studies with sufficient power in stages IIIA - 2, results in the absence of clear and consensual recommendations (except for stages IIIA - N2 resectable R0, since LungART and PORT-C studies). The objective of this article is to make an update on the place of postoperative radiotherapy in the management of stages IIIA - N2 following the publication of two recent randomized trials (PORT-C and LungART) but also compare them fort a better understanding of the current issues raised by these first published results.

Background: Acrylamide is classified as a probable human carcinogen by the International Agency for Research on Cancer but epidemiologic evidence on the carcinogenicity of acrylamide from dietary sources is limited.

Objectives: This study aimed to investigate the associations between dietary acrylamide and breast cancer risk in the NutriNet-Santé cohort, accounting for menopausal and hormone receptor status.

Methods: This prospective cohort study included 80,597 French females (mean ± SD age at baseline: 40.

Introduction: The SARS-CoV-2 pandemic has impacted the care of cancer patients. This study sought to assess the pandemic's impact on the clinical presentations and outcomes of newly referred patients with lung cancer from the Greater Paris area.

Methods: We retrospectively retrieved the electronic health records and administrative data of 11.

Purpose: We set out to demonstrate the benefit of using dose-intense cisplatin-based neoadjuvant chemotherapy in terms of overall survival and progression-free survival.

Methods: We searched through MEDLINE and Cochrane Library databases up to May 2021 to identify randomized clinical trials comparing the benefit of using cisplatin-based neoadjuvant chemotherapy followed by local treatment with local treatment alone for the treatment of locally advanced cervical cancer. The PRISMA statement was applied.

Immunotherapy has gained great interest in thoracic malignancies in the last decade, first in non-small cell lung cancer (NSCLC), but also more recently in small-cell lung cancer (SCLC) and malignant pleural mesothelioma (MPM). However, while 15-20% of patients will greatly benefit from immune checkpoint blockers (ICBs), a vast majority will rapidly exhibit resistance. Reasons for this are multiple: non-immunogenic tumors, immunosuppressive tumor microenvironment or defects in immune cells trafficking to the tumor sites being some of the most frequent.

Background: Evidence is accumulating that high dietary glycaemic index (GI) and glycaemic load (GL) are potential risk factors for several metabolic disorders (e.g. type-2 diabetes, cardiovascular diseases), but remains limited concerning cancer risk.

Background: Neurokinin (NK) 1 receptor antagonists (RAs), administered in combination with a 5-hydroxytryptamine-3 (5-HT ) RA and dexamethasone (DEX), have demonstrated clear improvements in chemotherapy-induced nausea and vomiting (CINV) prevention over a 5-HT RA plus DEX. However, studies comparing the NK RAs in the class are lacking. A fixed combination of a highly selective NK RA, netupitant, and the 5-HT RA, palonosetron (NEPA), simultaneously targets two critical antiemetic pathways, thereby offering a simple convenient antiemetic with long-lasting protection from CINV.

In locally advanced non-small-cell lung cancer (NSCLC), mediastinal staging is the cornerstone of the therapeutic decision and echoendoscopy is the most practiced exam to assess the lymph node involvement. We describe a rare case of endobronchial involvement by cells originating from a metastatic lymph node after endobronchial ultrasound (EBUS). A 64-year-old man was diagnosed with a squamous cell lung cancer with mediastinal nodal involvement proven by EBUS.

In 2018, dosing regimens of the two most prescribed immune check point inhibitors (ICI), nivolumab (Opdivo) and pembrolizumab (Keytruda), in the treatment of lung cancer were changed from weight-based dosing to fixed dosing. The aim of this study was to compare the economic impact of this change in our university hospital group and then across Ile-de-France, the most inhabited French region. A budget impact analysis (BIA) has been performed on the French public health insurance data.

Purpose: Human, material, and financial resources being limited, the organization of the care system must allow an efficient allocation of resources. The management of cancers leads to specific and repetitive care for which the reimbursement of transport costs represents a high cost. We carried out an analysis of the additional transport costs, linked to the care of patients in Île-de-France, in a center other than the radiotherapy center closest to their home.

Background: Excessive sugar intake is now recognized as a key risk factor for obesity, type 2 diabetes, and cardiovascular diseases. In contrast, evidence on the sugar-cancer link is less consistent. Experimental data suggest that sugars could play a role in cancer etiology through obesity but also through inflammatory and oxidative mechanisms and insulin resistance, even in the absence of weight gain.

Background: Brain metastases challenge daily clinical practice, and the mechanisms by which cancer cells cross the blood-brain barrier remain largely undeciphered. Angiopoietin-like 4 (ANGPTL4) proteolytic fragments have controversial biological effects on endothelium permeability. Here, we studied the link between ANGPTL4 and the risk of brain metastasis in cancer patients.

Background: To assess and compare the ability of five mobility indices to predict 6-month mortality in older patients with cancer.

Methods: All consecutive ambulatory older patients with cancer referred for a geriatric assessment before a cancer treatment decision were included in a prospective two-center cohort study (Physical Frailty in Elderly Cancer) between 2013 and 2017. The mobility indices compared were the short physical performance battery, gait speed, hand grip strength, the one-leg stance balance test, and repeated falls.

Background: Immunotherapy represents a new therapeutic approach in non-small cell lung carcinoma (NSCLC) with the potential for prolonged benefits. Because of the systemic nature and heterogeneity of tumoral diseases, as well as the immune restoration process induced by immunotherapy, the assessment of therapeutic efficacy is challenging, and the role of FDG PET is not well established. We evaluated the potential of FDG PET to monitor NSCLC patients treated with a checkpoint inhibitor.

Anti-PD1 immunotherapies have become an essential treatment for bronchial cancer. According to published studies, PD1 and PD-L1 inhibitors have a better toxicity profile than chemotherapy. Nevertheless, some immune related toxicities can be potentially severe, such as induced interstitial lung disease (ILD).

Background: Brain metastases are challenging daily practice in oncology and remain a compartmental problem since most anti-cancer drugs do not cross the blood-brain barrier at relevant pharmacological concentrations.

Methods: In a young woman with HER2-overexpressing breast cancer resistant to standard treatments, at the time of brain metastases progression, a ventricular reservoir was implanted for intrathecal drug injections and detailed pharmacokinetic studies.

Results: A first association of intrathecal trastuzumab with intravenous cisplatin was offered to the patient.
