Treatment of patients with multiple brain metastases by isolated radiosurgery: Toxicity and survival.

Background: Radiosurgery for multiple brain metastases has been more reported recently without using whole-brain radiotherapy. Nevertheless, the sparsity of the data still claims more information about toxicity and survival and their association with both dosimetric and geometric aspects of this treatment.

Aim: To assess the toxicity and survival outcome of radiosurgery in patients with multiple (four or more lesions) brain metastases.

Moderately hypofractionated post-operative radiation therapy for breast cancer: preferences amongst radiation oncologists from countries in Latin America and the Caribbean.

Background: The safety and effectiveness of moderately hypofractionated post-operative radiation therapy for breast cancer were demonstrated by several trials. This study aimed to evaluate the current patterns of practice and prescription preference about moderately hypofractionated post-operative radiation therapy to assess possible aspects that affect the decision-making process regarding the use of fractionation in breast cancer patients in Latin America and the Caribbean (LAC). We also aimed to identify factors that can restrain the utilization of moderately hypofractionated post-operative radiation therapy for breast cancer.

Efficacy and safety of a cisplatin and paclitaxel induction regimen followed by chemoradiotherapy for patients with locally advanced head and neck squamous cell carcinoma.

Background: The purpose of this phase II trial was to evaluate the tolerability, safety, and efficacy of a non-5-fluorouracil (5-FU)-based induction chemotherapy followed by chemoradiotherapy (CRT) for patients with locally advanced head and neck squamous cell carcinoma (HNSCC).

Methods: Sixty patients with stage III to IV HNSCC were treated with induction paclitaxel and cisplatin (TP; paclitaxel 175 mg/m(2) and cisplatin 80 mg/m(2) , 3 cycles) followed by CRT (cisplatin 100 mg/m(2) ; D1, 22, and 43 of radiotherapy).

Results: Fifty-six patients (93.
