Brain metastases (BM) are the most common form of intracranial cancer. The incidence BM seems to have increased over past decade. Recursive partitioning analysis (RPA) data from three Radiation Therapy Oncology Group (RTOG) trials (1200 patients) has allowed prognostic groups be identified. More recently a simplified stratification system that uses evaluation main prognostics factors for radiosurgery in was developed. To analyze overall survival rate (OS), affecting outcomes and estimate...
SUMMARY This recommendation consensus for hypofractionated whole-breast radiotherapy (RT) was organized by the Brazilian Society of Radiotherapy (SBRT) considering optimal scenario indication and safety in technology applied. All controversies contraindication matters (hypofractionated RT patients who underwent chemotherapy [CT], lymphatic drainage, after mastectomy with or without immediate reconstruction, boost during surgery, under 50 years old, large breasts, histology carcinoma situ...
Retinoblastoma is a malignant tumor of the embryonic neural retina. About 80% cases are diagnosed before age 4, with median at diagnosis 2 years.To determine characteristics and prognosis retinoblastoma in children older than 5 years.From 1986 to 2002, medical records 16 patients out 453 referred Hospital do Câncer AC Camargo, São Paulo, Brazil.Median was 73.7 months (range 65-144) there an equal gender distribution. Fifteen presented unilateral disease. The mean time between first symptoms...
To report the treatment results and prognostic factors of childhood patients with Hodgkin's disease treated chemotherapy (CT) followed by low dose radiotherapy (RT). This retrospective series analyzed 166 under 18 years old, from January 1985 to December 2003. Median age was 10 (range 2–18). The male female ratio 2,3 : 1. Lymphonode enlargement most frequent clinical manifestation (68%), time symptom duration less than 6 months in 55% patients. In histological analysis Nodular Sclerosis...
Pelvic Radiotherapy (RT) as a postoperative treatment for endometrial cancer improves local regional control. Brachytherapy also vaginal Both treatments imply significant side effects that fine RT technique can help avoiding. Intensity Modulated (IMRT) enables the of target volume while protecting normal tissue. It therefore reduces incidence and severity effects. We report on 50 year-old patient with serous-papiliferous adenocarcinoma uterus who was submitted to surgical without lymph node...
To evaluate the results of salvage conformal radiation therapy (3DC-EBRT) for patients submitted to radical prostatectomy (RP) who have achieved complete PSA response and never been treated with hormonal (HT).To present biochemical control, a period free from factors related its prognosis.from August 2002 December 2004, 43 prostate cancer RP presented failure after achieving < 0.2 ng/ml. They received HT were 3DC-EBRT. Median age was 62 years, median preoperative 8.8 ng/ml, Gleason Score 7....
The COVID-19 pandemic brought several challenges to cancer practice, especially in ensuring continuity of treatment during this period while minimizing the risks transmission a vulnerable population. For radiation oncology departments Brazil, contingency has become even more complex owing significant effect observed different sectors society and large number cases deaths. This study estimated on Brazilian coping measures used country.The Radiotherapy Society developed questionnaire, with 14...
To evaluate the pathologic response of cervical carcinoma to external beam radiotherapy (EBRT) and high dose rate brachytherapy (HDRB) outcome.Between 1992 2001, 67 patients with were submitted preoperative radiotherapy. Sixty-five stage IIb. Preoperative treatment included 45 Gy EBRT 12 HDRB. Patients surgery after a mean time 82 days. Lymphadenectomy was performed in 81% patients. Eleven residual cervix disease on pathological specimen 2 additional insertions HDRB.median follow up 72...
In Brazil, life expectancy among women is 75 years. The current population aged over 70 years exceeds 4.5 million, and expected to grow even more in the coming Contrary expectations, clinical outcome of breast cancer appears be similar both younger older women. Level I evidence randomized prospective studies involving patients than with are scarce. Early diagnosis using mammography enables less aggressive treatments. Therefore, need for mammographies should not overlooked elderly Surgical...
SUMMARY OBJECTIVE: Several prospective randomized trials have shown that hypofractionation has the same efficacy and safety as conventional fractionation in treatment of localized prostate cancer. There are many benefits hypofractionation, including a more convenient schedule for patients better use resources, which is especially important low- middle-income countries like Brasil. Based on these data, Brazilian Society Radiotherapy (Sociedade Brasileira de Radioterapia) organized this...
Background: Estimates show that breast cancer, the leading cause of cancer death in females worldwide, will continue to increase incidence, highlighting need for increased treatment capacity. While postoperative radiation therapy (RT) is commonly used reduce recurrence and mortality, research has shown moderately hypofractionated (HFRT) 5-fraction HFRT, are equally safe effective can costs. This study aimed compare cost conventional RT (50Gy/25), HFRT (40.05Gy/15), (26Gy/5) patients...
