Precision Medicine in Pancreatic Ductal Adenocarcinoma: The Impact of Targeted Therapies on Survival of Patients Harboring Actionable Mutations.

Background: Pancreatic ductal adenocarcinoma (PDAC) is the third leading cause of death by cancer worldwide. Mostly diagnosed with locally advanced or metastatic disease, patients lack treatment options. Gene alterations (GAs) are frequently observed in PDAC, some of which are considered for molecular targeted therapies (MTTs), with potential clinical benefits and improved outcomes.

Targetable Molecular Alterations in the Treatment of Biliary Tract Cancers: An Overview of the Available Treatments.

Biliary tract cancers (BTCs) are rare tumours, most often diagnosed at an unresectable stage, associated with poor prognosis, with a 5-year survival rate not exceeding 10%. Only first- and second-line treatments are well codified with the combination of cisplatin-gemcitabine chemotherapy and immunotherapy followed by 5-FU and oxaliplatin chemotherapy, respectively. Many studies have shown that BTC, and more particularly intrahepatic cholangiocarcinoma (iCCA), have a high rate of targetable somatic alteration.

Immunosuppressant mycophenolate mofetil for patients with steroid-refractory immune-related hepatitis induced by checkpoint inhibitors in oncology.

Background: Immune-checkpoint inhibitor (ICI) hepatitis, which does not improve with steroids and requires additional immunosuppressant, is defined as steroid-refractory ICI hepatitis. The outcome of patients with steroid-refractory ICI hepatitis remains poorly determined. Herein, we investigated the incidence, clinical features, and outcome of patients treated with second-line immunosuppressant for steroid-refractory ICI hepatitis.

Chemotherapy-induced ileitis associated or not with colitis in digestive oncology patients: An AGEO multicentre study.

Background: The characteristics and management of ileitis induced by chemotherapy in cancer patients are poorly described in the literature.

Methods: This retrospective multicentre study enroled patients hospitalized in a digestive oncology unit for a symptomatic chemotherapy-induced ileitis.

Results: Forty-three patients were included, with a regimen based on fluoropyrimidine and/or irinotecan in 95% of cases.

FOLFIRI plus BEvacizumab or aFLIbercept after FOLFOX-bevacizumab failure for COlorectal cancer (BEFLICO): An AGEO multicenter study.

After failure of first line FOLFOX-bevacizumab for metastatic colorectal cancer (mCRC), adding either bevacizumab or aflibercept to second-line FOLFIRI increases survival compared to FOLFIRI alone. In this French retrospective multicentre cohort, we included patients with a mCRC treated with either FOLFIRI-aflibercept or FOLFIRI-bevacizumab. The primary endpoint was overall survival (OS), and secondary endpoints were progression-free survival (PFS), disease control rate (DCR: CR + PR + SD) and safety.

Encorafenib plus cetuximab treatment in BRAF V600E-mutated metastatic colorectal cancer patients pre-treated with an anti-EGFR: An AGEO-GONO case series.

Background: Encorafenib plus cetuximab is efficient in anti-EGFR-naïve patients with BRAF mutated (BRAFm) metastatic colorectal cancer (mCRC). No data are available concerning the efficacy of BRAF inhibitors associated with anti-EGFRs (B + E) in patients previously treated with an anti-EGFR agent.

Methods: We retrospectively collected a series of patients with BRAFm mCRC treated with B + E after previous anti-EGFR treatment, in 14 centers.

Deprivation of direct adult contact during development affects social representation in a songbird.

Social cognition involves a wide array of skills that are built largely through interactions with conspecifics and therefore depend upon early social experience. Motivation for social stimuli is a key feature of social behavior and an operant conditioning task showed that isolated wild-caught adult starlings (Sturnus vulgaris) are highly motivated to access pictures of other starlings. Here, we show that hand-raised adult starlings maintained in groups of peers throughout development but without any contact with adult models were not or only poorly motivated to access pictures of conspecifics.

First-line chemotherapy with raltitrexed in metastatic colorectal cancer: an Association des Gastro-entérologues Oncologues (AGEO) multicentre study.

Background: In case of contraindication or intolerance to fluoropyrimidines, raltitrexed is a validated alternative in metastatic colorectal cancer (mCRC), associated or not with oxaliplatin. Little is known about the outcomes of raltitrexed combined with irinotecan or targeted therapies.

Methods: This retrospective multicentre study enroled mCRC patients treated with first-line raltitrexed-based chemotherapy.

Efficacy and safety of oral metronomic etoposide in adult patients with metastatic osteosarcoma.

Therapeutic options in patients with metastatic osteosarcoma are limited and effective systemic treatments are needed in this setting. The aim of this case series was to assess the efficacy and toxicity of oral metronomic etoposide in adult patients with progressive metastatic osteosarcoma. We retrospectively reviewed the electronic records of patients treated with oral metronomic etoposide (25 mg thrice daily, 3 weeks out of 4) from December 2002 to December 2018 at Gustave Roussy (Villejuif, France).

An appraisal of emerging second line therapies for metastatic colorectal cancer.

Introduction: Despite a significant improvement in overall survival over the last 15 years, colorectal cancer remains a major public health problem worldwide. Much effort has been made to develop an optimal choice of first-line treatments, but after progression the therapeutic possibilities and the criteria for choice are different.

Areas Covered: The purpose of this literature review is to discuss the different possibilities of second-line treatment and to specify the criteria for choice.

Social visual contact, a primary "drive" for social animals?

Social animals are always searching for conspecifics, thereby expressing a genuine "social need". This need is illustrated by the fact that social isolation can induce isolation syndromes that can be attenuated by devices such as mirrors. Social contacts appear to be so vital for social animals that they may be ready to work to obtain social stimulations.

Assessing video presentations as environmental enrichment for laboratory birds.

The aim of the present study was to investigate the effects of video presentations of natural landscapes on European starlings' (Sturnus vulgaris) stereotypic behaviours (SBs) and other abnormal repetitive behaviours (ARBs) and to evaluate the impact of past experience by comparing wild-caught and hand-reared starlings' reactions. Ten wild-caught and five hand-reared starlings were presented 1-hour videos of landscapes twice a day for five successive days, while a control group of eight wild-caught and four hand-reared starlings was presented a grey screen for the same amount of time. The analysis of the starlings' behaviour revealed that the video presentations of landscapes appeared to have a positive but limited and experience-dependent effect on starlings' SBs and other ARBs compared to the controls.
