Circulating tumour DNA at baseline for individualised prognostication in patients with chemotherapy-naïve metastatic colorectal cancer. An AGEO prospective study.

Purpose: Baseline circulating tumour DNA (ctDNA) is a potential prognostic marker in metastatic colorectal cancer (mCRC) patients. However, few studies have compared ctDNA with the usual prognostic factors, and no ctDNA cut-off has been proposed for daily use in clinical practice.

Patients And Methods: Chemotherapy-naive patients with mCRC were prospectively included.

Modified FOLFIRINOX Versus CISGEM Chemotherapy for Patients With Advanced Biliary Tract Cancer (PRODIGE 38 AMEBICA): A Randomized Phase II Study.

Purpose: Whether triplet chemotherapy is superior to doublet chemotherapy in advanced biliary tract cancer (BTC) is unknown.

Methods: In this open-label, randomized phase II-III study, patients with locally advanced or metastatic BTC and an Eastern Cooperative Oncology Group performance status of 0 or 1 were randomly assigned (1:1) to receive oxaliplatin, irinotecan, and infusional fluorouracil (mFOLFIRINOX), or cisplatin and gemcitabine (CISGEM) for a maximum of 6 months. We report the results of the phase II part, where the primary end point was the 6-month progression-free survival (PFS) rate among the patients who received at least one dose of treatment (modified intention-to-treat population) according to Response Evaluation Criteria in Solid Tumors version 1.

Metastatic colorectal carcinoma with signet-ring cells: Clinical, histological and molecular description from an Association des Gastro-Entérologues Oncologues (AGEO) French multicenter retrospective cohort.

Background: Metastatic signet-ring cell colorectal carcinoma is rare. We analyzed its clinicopathological and molecular features, prognostic factors and chemosensitivity.

Methods: Retrospective study from 2003 to 2017 in 31 French centers, divided into three groups: curative care (G1), chemotherapy alone (G2), and best supportive care (G3).

Prognostic factors of colorectal cancer patients with brain metastases.

Introduction: Brain metastases (BMs) from colorectal cancer (CRC) are rare (≈2%) but are increasing with the improvement of CRC prognosis. The main objective of this study was to evaluate the prognostic factors of BM from CRC.

Materials And Methods: This multicenter retrospective study included all consecutive patients with BM from CRC diagnosed between 2000 and 2017.

Gemcitabine plus nab-paclitaxel until progression or alternating with FOLFIRI.3, as first-line treatment for patients with metastatic pancreatic adenocarcinoma: The Federation Francophone de Cancérologie Digestive-PRODIGE 37 randomised phase II study (FIRGEMAX).

Background: Chemotherapy is effective in metastatic pancreatic adenocarcinoma (mPA), but new approaches are still needed to improve patients' survival and quality of life. We have previously published good efficacy and tolerability results on a sequential treatment strategy of gemcitabine followed by an intensified FOLFIRI (5FU+irinotecan) regimen. In the present study, we evaluated the same sequence but replaced gemcitabine by the new gemcitabine + nab-paclitaxel standard first-line combination.

Nal-IRI/LV5-FU versus paclitaxel as second-line therapy in patients with metastatic esophageal squamous cell carcinoma (OESIRI)-PRODIGE 62: A multicentre, randomised, non-comparative phase II study.

Half of patients newly diagnosed with esophageal squamous cell cancer (ESCC) have metastatic disease (mESCC) and therefore a poor prognosis. Furthermore, half of patients with initial loco-regional disease present disease recurrence after surgery and/or chemoradiation. In mESCC, the recommended first-line treatment combines 5-fluorouracil and cisplatin, although this has not been validated by a phase III trial.

Mutation Status in Circulating Tumor DNA from Patients with Metastatic Colorectal Cancer: Extended Mutation Analysis from the AGEO RASANC Study.

In patients with metastatic colorectal cancer (mCRC), and mutations are currently determined by tumor sample analysis. Here, we report mutation status analysis in paired tumor tissue and plasma samples of mCRC patients included in the AGEO RASANC prospective cohort study. Four hundred and twenty-five patients were enrolled.

Characteristic and outcomes of patients with pathologic complete response after preoperative treatment in borderline and locally advanced pancreatic adenocarcinoma: An AGEO multicentric retrospective cohort.

Introduction: Following publication of improved patients' outcome using first line FOLFIRINOX for metastatic pancreatic adenocarcinoma, many physicians now prescribe it as neo-adjuvant or induction treatment for borderline and locally advanced pancreatic cancer. A pathologic complete response, rarely seen with previous preoperative regimens, is sometimes observed in these patients. The aim of this study was to assess long-term outcomes of patients presenting pathologic complete response after preoperative FOLFIRINOX usually followed by chemo-radiation therapy for non-metastatic pancreatic adenocarcinoma.

Trastuzumab beyond progression in patients with HER2-positive advanced gastric adenocarcinoma: a multicenter AGEO study.

Introduction: Trastuzumab in combination with platinum-based chemotherapy is the standard first-line regimen in HER2-positive advanced gastric cancer. However, there are very few data concerning efficacy of continuing trastuzumab beyond first-line progression.

Methods: This retrospective multicenter study included all consecutive patients with HER2-positive advanced gastric or gastro-esophageal junction (GEJ) adenocarcinoma who received a second-line of chemotherapy with or without trastuzumab after progression on platinum-based chemotherapy plus trastuzumab.

Trastuzumab in Combination with FOLFIRI in Patients with Advanced HER2-Positive Gastro-Esophageal Adenocarcinoma: A Retrospective Multicenter AGEO Study.

Background: Trastuzumab with fluoropyrimidine and cisplatin is the standard first-line treatment in patients with HER2-positive advanced gastro-esophageal adenocarcinoma. However, there are no safety and efficacy data of trastuzumab with FOLFIRI.

Objective: To evaluate safety and efficacy of FOLFIRI plus trastuzumab in patients with HER2-positive advanced gastro-esophageal adenocarcinoma.

Nutritional status affects treatment tolerability and survival in metastatic colorectal cancer patients: results of an AGEO prospective multicenter study.

Background: The possible impact of malnutrition on the tolerability and efficacy of modern chemotherapy regimens for metastatic colorectal cancer (mCRC) is unclear.

Methods: In this prospective, cross-sectional, multicenter study, we collected demographic, oncological and nutritional data for all consecutive mCRC patients during a 14-day period in eight hospitals. Nutritional status was assessed with the nutritional risk index (NRI), and patients were classified as severely malnourished when NRI was <83.

Human CD90 identifies Th17/Tc17 T cell subsets that are depleted in HIV-infected patients.

By revisiting CD90, a GPI-anchored glycoprotein, we show that CD90 is expressed by a subset of CD4(+) and CD8(+) human T cells. CD4(+)CD90(+) cells share similarities with Th17 cells because they express the Th17-specific transcription factor RORC2 and produce IL-17A. CD4(+)CD90(+) cells are activated memory T cells that express the gut mucosal markers CCR6, CD161, and the α(4) and β(7) integrins.

Gemcitabine plus oxaliplatin (GEMOX) in patients with advanced hepatocellular carcinoma (HCC): results of a phase II study.

Background: New systemic therapies are needed to improve the prognosis of patients with advanced-stage hepatocellular carcinoma (HCC). In a Phase II trial involving previously untreated patients with advanced HCC, the more favorable schedule from a previous pilot study was evaluated.

Methods: Thirty-four patients with previously untreated advanced-stage HCC were prospectively enrolled.

Geographical variations of inflammatory bowel disease in France: a study based on national health insurance data.

Background And Aim: A north-south gradient in inflammatory bowel disease (IBD) incidence has been found in Europe and the United States. Its existence is inferred from comparisons of registries that cover only small portions of territories. Several studies suggest that IBD incidence in the north has reached a plateau, whereas in the south it has risen sharply.

[Oxaliplatin in gastro-intestinal tract cancer except colorectal cancer].

In a few years, oxaliplatin became a standard treatment of colorectal cancer not only in metastatic situation but also in the adjuvant setting. In the others gastro-intestinal malignancies such as oesophageal, stomach, pancreatic, liver and biliary tract cancers, the effectiveness of the current chemotherapies is unfortunately most often disappointing. Several teams thus decided to evaluate oxaliplatin, essentially in polychemotherapy regimens and sometimes in combination with radiotherapy.
