Survival Without Quality of Life Deterioration in the GORTEC 2014-04 "OMET" Randomized Phase 2 Trial in Patients with Head and Neck Cancer with Oligometastases using Stereotactic Ablative Radiation Therapy (SABR) alone or Chemotherapy and SABR.

Purpose: Patients with oligometastasis may have prolonged survival with multisite stereotactic ablative radiation therapy (SABR). Evidence to support this paradigm is scarce in squamous cell carcinoma of the head and neck (HNSCC). The multicenter open-label randomized GORTEC 2014-04 (NCT03070366) phase 2 study assesses survival without definitive quality of life (QoL) deterioration of omitting upfront chemotherapy in oligometastatic patients with HNSCC using SABR alone, in the French Head and Neck Intergroup.

Clinical and Oncological Impact of a Protective Ileostomy in Rectal Cancer Patients Undergoing Adjuvant Chemotherapy.

Background/aim: During low anterior rectal resection for rectal cancer, a protective ileostomy (PI) is routinely created to reduce the severity of anastomotic complications. The aim of this study was to investigate the side-effects of PI during adjuvant chemotherapy.

Patients And Methods: A retrospective cohort of patients was operated on for non-metastatic rectal cancer with a PI during 2005-2022.

Cost-effectiveness of weekly adaptive radiotherapy versus standard IMRT in head and neck cancer alongside the ARTIX trial.

Background And Purpose: We performed a cost-effectiveness analysis (CEA) comparing an adaptive radiotherapy (ART) strategy, based on weekly replanning, aiming to correct the parotid gland overdose during treatment and expecting therefore to decrease xerostomia, when compared to a standard IMRT.

Materials And Methods: We conducted the ARTIX trial, a randomized, parallel-group, multicentric study comparing a systematic weekly replanning ART to a standard IMRT. The primary endpoint was the frequency of xerostomia at 12 months, measured by stimulating salivary flow with paraffin.

Outcomes and Side Effects of Preoperative Chemoradiotherapy for Locally Advanced Upper Rectal Cancer.

Background/aim: The benefit of neoadjuvant (chemo) radiotherapy for locally advanced upper rectal tumors remains controversial. Thus, we aimed to evaluate the outcome of patients with stage II or-III upper rectal cancer undergoing neoadjuvant (chemo) radiotherapy followed by total mesorectal excision in our institution.

Patients And Methods: From April 2004 to October 2019, all patients with stage II or III upper rectal cancer treated with neoadjuvant (chemo) radiotherapy followed by total mesorectal excision were identified from our database.

Simultaneous or staged resection for synchronous liver metastasis and primary rectal cancer: a propensity score matching analysis.

Background: Colorectal cancer is the third most common cancer in France and by the time of the diagnosis, 15-25% of patients will suffer from synchronous liver metastases. Surgery associated to neoadjuvant treatment can cure these patients, but few studies focus only on rectal cancer. This study was meant to compare the outcomes of patients who underwent a simultaneous resection to those who underwent a staged resection (rectum first or liver first) in the University Hospital of Tours, France.

Impact of Modern Management Strategies on the Clinical Outcome of Patients With Low Rectal Cancer - A Retrospective, Monocentric Cohort Study.

Background: The aim of this study was to retrospectively investigate the impact of intersphincteric resection (ISR) and Enhanced Recovery After Surgery (ERAS) protocols for rectal cancer.

Patients And Methods: Since we implemented rectal ERAS protocol and ISR in 2016, we retrospectively assessed and compared clinical, pathological and survival outcomes of two groups of patients: group 1, treated 2000-2015 (n=242); and group 2, treated 2016-2020 (n=108). Propensity score matching using nearest-neighbor method was used to match each patient of group 1 to a patient of group 2.

Prognostic Impact of Upfront Surgery for Locally Advanced Upper Rectal Adenocarcinoma.

Background/aim: Impact of neoadjuvant chemoradiotherapy (CRT) in locally advanced upper rectal adenocarcinoma (LAURC) is debated. The aim of this study was to compare outcomes between LAURC and locally advanced sigmoid and recto-sigmoid junction cancer (LASC).

Patients And Methods: This retrospective study included 149 consecutive patients [42 CRT/LAURC, 16 upfront surgery (US/LAURC) and 91 LASC].

Hypofractionated stereotactic body radiation therapy (SBRT) in pediatric patients: preliminary toxicity results of a national prospective multicenter study.

Objectives: While hypofractionated stereotactic body radiotherapy (SBRT) has been largely adopted in the adult setting, its use remains limited in pediatric patients. This is due, among other factors, to fear of potential toxicities of hypofractionated regimens at a young age. In this context, we report the preliminary acute (<3 months from SBRT) and middle-term (3-24 months) toxicity results of a national prospective study investigating SBRT in pediatric patients.

Exclusive Hyperfractionated Radiation Therapy and Reduced Boost Volume for Standard-Risk Medulloblastoma: Pooled Analysis of the 2 French Multicentric Studies MSFOP98 and MSFOP 2007 and Correlation With Molecular Subgroups.

Purpose: Medulloblastoma has recently been characterized as a heterogeneous disease with 4 distinct molecular subgroups: wingless (WNT), sonic hedgehog (SHH), group 3, and group 4, with a new definition of risk stratification. We report progression-free survival, overall survival, and long-term cognitive effects in children with standard-risk medulloblastoma exclusively treated with hyperfractionated radiation therapy (HFRT), reduced boost volume, and online quality control, and we explore the prognostic value of biological characteristics in this chemotherapy-naïve population.

Methods And Materials: Patients with standard-risk medulloblastoma were enrolled in 2 successive prospective multicentric studies, MSFOP 98 and MSFOP 2007, and received exclusive HFRT (36 Gy, 1 Gy/fraction twice daily) to the craniospinal axis followed by a boost at 68 Gy restricted to the tumor bed (1.
