Article Synopsis
  • The review examines how radiotherapy is used for treating extremity soft tissue sarcomas, looking at its effects on local control, survival rates, and complications.
  • It will compare preoperative and postoperative radiotherapy approaches to highlight their distinct roles in treatment.
  • The paper aims to provide consensus recommendations on how to define radiation target volumes effectively.

Background And Purpose: In this study, we explore the quality aspects of radiation care from the patient's perspective in order to develop a draft Consumer Quality Index (CQI) Radiation Care instrument.

Materials And Methods: Four focus group discussions with (former) cancer patients were held to explore the aspects determining the quality of radiation care. The list of aspects generated was categorised based on similarity and importance in a concept mapping procedure.

Background: The purpose of this study was to study the effect of intensive targeted chemoradiation in a group of patients with head and neck cancer with stage IV inoperable disease.

Methods: We examined 79 patients with inoperable stage IV head and neck cancer receiving intra-arterial infusion of high-dose cisplatin (150 mg/m(2)) on days 2, 9, 16, and 23 concomitant with delivery of external beam radiotherapy (total dose, 70 Gy; 2 Gy, 35 fractions; 1 fraction/day for 7 weeks). Sodium thiosulfate was administered intravenously to provide effective cisplatin neutralization.

Background: To investigate the impact of T stage according to Wang on the prognosis of irradiated nasal vestibule carcinoma.

Patients And Methods: Treatment results of 47 patients were retrospectively analyzed. Treatment consisted of external beam radiotherapy (n = 26) or interstitial radiotherapy (n = 19) or a combination of both (n = 2) for a primary, localized, squamous cell carcinoma of the nasal vestibule.

Purpose: To estimate the risk of ischemic stroke in patients irradiated for head and neck tumors.

Patients And Methods: The incidence of ischemic stroke was determined in 367 patients with head and neck tumors (162 larynx carcinomas, 114 pleomorphic adenomas, and 91 parotid carcinomas) who had been treated with local radiotherapy (RT) at an age younger than 60 years. Relative risk (RR) of ischemic stroke was determined by comparison with population rates from a stroke-incidence register, adjusted for sex and age.
