REVIEW
Cyrus Chargari, Pierre Maroun, Ioana Lazarescu, Christine Haie-Meder
The adjuvant management of uterine endometrial cancer has been studied in many randomized trials, leading to define postoperative therapeutic indications, depending on the risk factors for relapse, and on the expected benefit in terms of locoregional control and survival. The potential toxicity of treatments should be also considered. We review the available literature that yielded to guidelines that were recently published, on behalf of European societies, and we highlight the perspectives on ongoing studies, aimed at better defining the place and type of adjuvant treatment...

PURPOSE: Brachytherapy (BT) is an effective organ-preserving treatment for selected localized penile carcinoma, providing high local control rates. Long-term functional results however, are still insufficiently evaluated. METHODS AND MATERIALS: All consecutive patients treated with low-dose-rate or pulse-dose-rate BT in our institute for a localized penile cancer and who were in first complete remission and followed for at least 3 years were included. A self-reporting questionnaire was sent, to assess: 1/urinary function, 2/sexual function, 3/cosmetic aspect of the penis, and 4/quality of life...

PURPOSE: We investigated whether a score combining baseline neutrophilia and a PET biomarker could predict outcome in patients with locally advanced cervical cancer (LACC). METHODS: Patients homogeneously treated with definitive chemoradiation plus image-guided adaptive brachytherapy (IGABT) between 2006 and 2013 were analyzed retrospectively. We divided patients into two groups depending on the PET device used: a training set (TS) and a validation set (VS). Primary tumors were semi-automatically delineated on PET images, and 11 radiomics features were calculated (LIFEx software)...

Radiation induced gastroparesis as well as the other autonomic nervous system radiation induced neuropathies are poorly described in the literature. A case of gastroparesis associated with phrenic and recurrent laryngeal nerves paralysis was observed in a 69-year old patient. She was already treated two times by rachis radiotherapy in a context of breast cancer with bone metastases. Anatomical and chronological correlation of lesions, concomitant nerve damage in the radiation fields and elimination of the main differential diagnoses allowed us to link this case of gastroparesis with the background of radiotherapy...

BACKGROUND: Neutrophils are the most abundant blood-circulating white blood cells, continuously generated in the bone marrow. Growing evidence suggests they regulate the innate and adaptive immune system during tumor evolution. This review will first summarize the recent findings on neutrophils as a key player in cancer evolution, then as a potential biomarker, and finally as therapeutic targets, with respective focuses on the interplay with radiation therapy. A complex interplay: Neutrophils have been associated with tumor progression through multiple pathways...

PURPOSE: Radiotherapy of nasal carcinomas results in cure rates comparable to surgery, with anatomic preservation and good cosmesis. Brachytherapy (BT) overcomes difficulties with dosimetric coverage and affords a localized and highly conformal irradiation. We report our experience of BT for early-stage nasal squamous cell carcinomas (SCCs). METHODS AND MATERIALS: Clinical data, BT parameters, and outcome of consecutive patients treated by interstitial BT in our institute between December 1982 and April 2015 for a localized nasal SCC were examined...

The management of Non Small Cell Lung Cancer (NSCLC) brain metastases is challenging, as this frequent complication negatively impacts patients' quality of life, and can be a life-threatening event. Through a review of the literature, we discuss the main therapeutic options and the recent developments that improved (and complicated) the management of NSCLC brain metastases patients. Most current validated approaches are local with exclusive or combined surgery, whole brain radiotherapy (WBRT) and stereotactic radiotherapy (SRT)...

Several therapeutic agents targeting HGF/MET signaling are under clinical development as single agents or in combination, notably with anti-EGFR therapies in non-small cell lung cancer (NSCLC). However, despite increasing data supporting a link between MET, irradiation, and cancer progression, no data regarding the combination of MET-targeting agents and radiotherapy are available from the clinic. S49076 is an oral ATP-competitive inhibitor of MET, AXL, and FGFR1-3 receptors that is currently in phase I/II clinical trials in combination with gefitinib in NSCLC patients whose tumors show resistance to EGFR inhibitors...

OBJECTIVES: To identify an imaging signature predicting local recurrence for locally advanced cervical cancer (LACC) treated by chemoradiation and brachytherapy from baseline 18F-FDG PET images, and to evaluate the possibility of gathering images from two different PET scanners in a radiomic study. METHODS: 118 patients were included retrospectively. Two groups (G1, G2) were defined according to the PET scanner used for image acquisition. Eleven radiomic features were extracted from delineated cervical tumors to evaluate: (i) the predictive value of features for local recurrence of LACC, (ii) their reproducibility as a function of the scanner within a hepatic reference volume, (iii) the impact of voxel size on feature values...
