International assessment of interobserver reproducibility of flap delineation in head and neck carcinoma.

Several reports have suggested that radiotherapy after reconstructive surgery for head and neck cancer (HNC), could have deleterious effects on the flaps with respect to functional outcomes. To predict and prevent toxicities, flap delineation should be accurate and reproducible. The objective of the present study was to evaluate the interobserver variability of frequent types of flaps used in HNC, based on the recent GORTEC atlas.

Adjuvant radiotherapy versus early salvage radiotherapy plus short-term androgen deprivation therapy in men with localised prostate cancer after radical prostatectomy (GETUG-AFU 17): a randomised, phase 3 trial.

Background: Adjuvant radiotherapy reduces the risk of biochemical progression in prostate cancer patients after radical prostatectomy. We aimed to compare adjuvant versus early salvage radiotherapy after radical prostatectomy, combined with short-term hormonal therapy, in terms of oncological outcomes and tolerance.

Methods: GETUG-AFU 17 was a randomised, open-label, multicentre, phase 3 trial done at 46 French hospitals.

[Chemoradiation for oesophageal cancer: A critical review of the literature].

Locally advanced oesophageal cancer treatment requires a multidisciplinary approach with the combination of chemotherapy and radiotherapy for preoperative and definitive strategy. Preoperative chemoradiation improves the locoregional control and overall survival after surgery for locally advanced oesophageal cancer. Definitive chemoradiation can also be proposed for non-resectable tumours or medically inoperable patients.

Does regional lymph node irradiation improve the outcome of N0 and pN0 breast cancer?

This study compares the outcome of 76 patients with N0 breast carcinoma, node-negative at axillary lymph node dissection (pN0) after neoadjuvant chemotherapy (NeoCT), treated with (RLNI+, 39 patients) or without (RLNI-, 37 patients) elective regional lymph node areas irradiation. For RLNI- and RLNI+ groups respectively at 10 years, survival without local-regional recurrence was 95% and 91% (p = .59), survival without distant metastasis was 97% and 78% (p = .

Temozolomide treatment of an adult with a relapsing medulloblastoma.

Temozolomide is an oral cytotoxic agent that has demonstrated its interest in high grade glioma tumors. This drug can be used either concomitantly with radiotherapy or as chemotherapy. The prognosis of relapsing medulloblastoma is poor and treatment is often difficult, especially after radiotherapy.

[Docetaxel and gemcitabine combination in soft-tissue sarcomas treatment].

Soft-tissue sarcomas (STS) are usually sensitive to doxorubicine and/or ifosfamide. When tumors become refractory to these two drugs, chemotherapeutic options are limited. All the drugs tested generally yield occasional or negligible response, with response rates lower than 20% and a poor duration of response.

Successful mitigation of delayed intestinal radiation injury using pravastatin is not associated with acute injury improvement or tumor protection.

Purpose: To investigate whether pravastatin mitigates delayed radiation-induced enteropathy in rats, by focusing on the effects of pravastatin on acute cell death and fibrosis according to connective tissue growth factor (CTGF) expression and collagen inhibition.

Methods And Materials: Mitigation of delayed radiation-induced enteropathy was investigated in rats using pravastatin administered in drinking water (30 mg/kg/day) 3 days before and 14 days after irradiation. The ileum was irradiated locally after surgical exteriorization (X-rays, 19 Gy).

Radiotherapy of pituitary adenomas: state of the art.

Pituitary adenomas represent approximately 12% of intracranial tumors. They are defined as tumors that are functional or nonfunctional and invasive or noninvasive. Therapeutic strategies rely on surgery, medical treatment, and radiotherapy depending on histology.

[Quantification of prostate movements during radiotherapy].

Decrease treatment uncertainties is one of the most important challenge in radiation oncology. Numerous techniques are available to quantify prostate motion and visualise prostate location day after day before each irradiation: CT-scan, cone-beam-CT-Scan, ultrason, prostatic markers..
