Clinical outcomes of adapted hypofractionated radiotherapy for bladder cancer in elderly patients.

Objective: To investigate the feasibility, efficacy, and safety of trimodal therapy (TMT) using a bifractionated split-course hypofractionated radiotherapy (RT) for non-metastatic muscle-invasive bladder cancer (MIBC) in elderly patients.

Patients And Methods: We retrospectively reviewed the characteristics and outcomes of patients aged >75 years with non-metastatic MIBC suitable or not for radical cystectomy (RC) and treated with transurethral resection of bladder tumour followed by concomitant radio-chemotherapy (platinum salt and 5-fluorouracil) at two institutions (Saint Louis Hospital, Paris, France and European Georges Pompidou Hospital, Paris, France) between 1990 and 2021. RT consisted of an adapted bifractionated split-course hypofractionated RT.

Ten-Year Outcomes of Hypofractionated Postmastectomy Radiation Therapy of 26 Gy in 6 Fractions.

Purpose: To investigate the efficacy and long-term side effects of hypofractionated postmastectomy radiation therapy (HFRT-PM) of 26 Gy in 6 fractions over 5 weeks.

Methods And Materials: We retrospectively reviewed characteristics and outcomes of patients with stage I to III breast cancer treated with HFRT-PM between 2000 and 2009. Treatment provided 4 fractions of 4 Gy (days 1, 3, 15, 17) and then 2 fractions of 5 Gy (days 29 and 31) over 5 weeks.

[Place of radiotherapy in the treatment of cutaneous carcinomas].

Basal cell carcinomas and cutaneous squamous cell carcinomas are among the most common cancerous tumors in the world. Their treatment is most often based on surgery. Adjuvant radiotherapy may be indicated in case of risk factors for recurrence or as an alternative to surgery if surgery is not feasible due to the patient's advanced age and/or co-morbidities or as an alternative to potentially mutilating surgery.

In vitro effects of Trastuzumab Emtansine (T-DM1) and concurrent irradiation on HER2-positive breast cancer cells.

Background: To determine the effects of concurrent irradiation and T-DM1 on HER2-positive breast cancer cell lines.

Methods: Five human breast cancer cell lines (in vitro study) presenting various levels of HER2 expression were used to determine the potential therapeutic effect of T-DM1 combined with radiation. The toxicity of T-DM1 was assessed using viability assay and cell cycle analysis was performed by flow cytometry after BrdU incorporation.

Incorporating Magnetic Resonance Imaging (MRI) Based Radiation Therapy Response Prediction into Clinical Practice for Locally Advanced Cervical Cancer Patients.

In recent years, magnetic resonance imaging (MRI) has become one of the standard imaging tools to define the macroscopic gross tumor volume in locally advanced cervical cancer patients based on T2-weighted sequence. Recent data suggest that functional MRI could be used to potentially improve the delineation of target volumes based on physiologic features, defining radioresistant subvolumes that may require higher doses to achieve local cure. Functional imaging can be used to predict tumor biology and outcome, as well as for assessment of tumor response during radiotherapy.

Esophageal brachytherapy: Institut Gustave Roussy's experience.

Purpose: Esophageal cancer is characterized by its propension to local evolution, which conditions prognosis and quality of life. Brachytherapy may be a therapeutic option for all stages of esophageal cancer.

Methods And Materials: This retrospective unicentric study included all consecutive patients treated for an esophageal high-dose-rate brachytherapy in our institution from 1992 to 2018.

Comprehensive analysis of patient outcome after local recurrence of locally advanced cervical cancer treated with concomitant chemoradiation and image-guided adaptive brachytherapy.

Introduction: Since dose escalation allowed by image-guided adaptive brachytherapy (IGABT) in locally advanced cervical cancer (LACC), local relapses have become a rare event. Only scarce data are available on the outcome of patients experiencing a local relapse after IGABT.

Methods: Between 2004 and 2016, all consecutive patients treated at Gustave Roussy Institute for LACC and receiving concomitant chemoradiation and IGABT were analysed.

Solitary Plasmacytoma Treated by Lenalidomide-Dexamethasone in Combination with Radiation Therapy: Clinical Outcomes.

Purpose: The study evaluates the results of the concurrent use of lenalidomide-dexamethasone with intensity modulated radiation therapy (IMRT) for solitary plasmacytoma in terms of toxicity and outcome.

Methods And Materials: Forty-six patients were treated for histologically proven solitary plasmacytoma (SP) between June 2007 and June 2018 in our Department (Curie Institute, Paris, France). All patients received IMRT.

Increased bone marrow SUVmax on 18F-FDG PET is associated with higher pelvic treatment failure in patients with cervical cancer treated by chemoradiotherapy and brachytherapy.

The aim of this study was to evaluate if bone marrow (BM) SUVmax measured on pre-treatment 18F-FDG PET/CT predicts the clinical outcome of locally advanced cervical cancer (LACC). We recruited retrospectively patients with LACC who underwent staging 18F-FDG PET/CT and had baseline blood tests, then treated by chemoradiation therapy (CRT), followed by image-guided adaptive brachytherapy (IGABT). BM SUVmax was calculated and correlated to inflammatory blood markers.

Radiobiological optimization comparison between pulse-dose-rate and high-dose-rate brachytherapy in patients with locally advanced cervical cancer.

Purpose: Only scarce data are available on the possibility to include radiobiological optimization as part of the dosimetric process in cervical cancer treated with brachytherapy (BT). We compared dosimetric outcomes of pulse-dose-rate (PDR) and high-dose-rate (HDR)-BT, according to linear-quadratic model.

Methods And Materials: Three-dimensional dosimetric data of 10 consecutive patients with cervical cancer undergoing intracavitary image-guided adaptive PDR-BT after external beam radiation therapy were examined.

Disseminated Tumor Cells Predict Efficacy of Regional Nodal Irradiation in Early Stage Breast Cancer.

Purpose: Disseminated tumor cells (DTCs) collect in the bone marrow and indicate micrometastatic spread. We previously reported that DTCs could be a predictive factor for the efficacy of regional node irradiation (internal mammary nodes [IMNs]/supra- and infraclavicular nodes [SCNs]). In this article, we report the long-term results (>10 years) on the impact of DTC status in early stage breast cancer.

Tumor Shrinkage During Chemoradiation in Locally Advanced Cervical Cancer Patients: Prognostic Significance, and Impact for Image-Guided Adaptive Brachytherapy.

Purpose: To study the prognostic value of gross tumor volume (GTV) shrinkage and its dosimetric implication in a large cohort of patients with cervical cancer receiving definitive chemoradiotherapy plus image guided adaptive brachytherapy.

Methods And Materials: Clinical records of consecutive patients treated in our institution between February 2004 and November 2015 by concurrent chemoradiotherapy (45 Gy in 25 fractions ± lymph node boosts) followed by a magnetic resonance imaging-guided adaptive pulse-dose rate brachytherapy were included. The prognostic value of GTV and its evolution after chemoradiotherapy were examined first on initial staging magnetic resonance imaging and then at time of brachytherapy.

Concurrent administration of anti-HER2 therapy and radiotherapy: Systematic review.

Background: Over the past few years, anti-HER2 targeted therapies have proven to be a key treatment in the management of human epidermal growth receptor 2 (HER2)-positive breast cancers, as well as gastrointestinal tract tumors and head and neck tumors. Anti-HER2 therapies administered alone or in combination with chemotherapy have been extensively studied, but only limited robust data are available concerning the safety and efficacy of anti-HER2 molecules in combination with radiotherapy.

Methods: We searched on Medline, Embase and Cochrane databases the articles providing data on the concomitant association between the antiHER2 therapies used in clinical practice (trastuzumab, pertuzumab, lapatinib and T-DM1) with radiotherapy.

[Traumatic uterine rupture: a rare complication of motor vehicle accidents during pregnancy. A case report].

The rupture of gravid uterus is a rare complication concerning less than one percent of the pregnant women involved in a motor vehicle accident. The authors report the case of a 39-year woman, gravida 4, referred for an uterine rupture with intrauterine fetal death at 24 weeks gestation, following a car crash. The surgical laparotomic exploration in emergency showed a wide fundal uterine tear with placental abruption.
