The accuracy of external beam radiotherapy has improved rapidly in recent years with the advancement of technology. New modalities like three‐dimensional (3D) conformal radiotherapy, IMRT (intensity modulated radiotherapy) based on multi‐leaf collimator (MLC) and Tomotherapy technology for cancer treatments have been adopted in radiotherapy centers. In many developing countries like India these...

AIMS AND BACKGROUND Esophageal cancer patients with pathologic lymph node involvement generally have a poor prognosis. Many randomized controlled trials have not achieved consistent results similar to those of the RTOG8501 trial, and the long-term survival rate has not increased. The present study aimed to compare the efficacy and toxic side effects of concurrent chemoradiotherapy and radiother...

Background: Three-dimensional conformal radiotherapy is a new tool in the Senegalese therapeutic arsenal. Symptomatic bone metastases affect quality of life patients. Analgesic proposed to patients relieve them. Patients and methods: A prospective descriptive study was carried out on all with symptomatic metastasis. Hypo-fractionated performed painful site. The visual analogue scale used assess...

PURPOSE Although the technical developments of radiotherapy have been remarkable, there are currently few reports on the treatment results of radiotherapy for local recurrence of rectal cancer treated with surgery alone as initial treatment in this three-dimensional conformal radiotherapy era. Thus, we retrospectively evaluated the treatment results of radiotherapy for local recurrence of recta...

We propose a comparative dosimetric study of whole-breast hypofractionated radiation therapy using helical tomotherapy (HT) in supine position and 3-D conformal radiotherapy (3D-CRT) in prone position. Twelve patients undergoing breast-conserving therapy were retrospectively selected from October to December 2012. Specific dose-volume parameters were selected for the study. The target coverage ...

PURPOSE To retrospectively evaluate the efficacy and toxicity of adjuvant radio-chemotherapy in patients with gastric cancer and to relate them to the outcome of the landmark INT0116 study that is criticized because of the high toxicity and poor treatment compliance. METHODS A total of 102 patients who underwent postoperative fluorouracil (5-FU)-based radio-chemotherapy in our institution bet...

Abstract Background Cancer is one of the leading causes death worldwide. According to GLOBOCAN estimates, there were 341,831 deaths from cervical cancer in 185 countries 2020. The aim this study was compare equieffective dose (EQD 2 ) at Gy per fraction by using volume histograms (DVHs) derived external beam radiotherapy (EBRT) and high-dose rate brachytherapy (HDR-BRT) treatment plans used rad...

Though adjuvant radiotherapy has an established role in the treatment of carcinoma breast, there is concern regarding irradiation to heart and lung, more on left sided disease. Intensity Modulated Radiation Therapy (IMRT) modulates intensity radiation beams with better accuracy, sparing surrounding normal organs. But it increases integral dose healthy tissues compared 3-Dimensional Conformal (3...
