Evaluation of incidental testicular dose with thermoluminescence dosimetry during prostate radiotherapy.

The aim of this study was to investigate incidental testicular doses during intensity modulated radiation therapy (IMRT) in patients treated with prostate radiotherapy only (PORT) and whole pelvis radiotherapy (WPRT). A total of 34 prostate cancer patients with intermediate and high risk were included in this prospective study. Each patient in the intermediate risk group received a total of 78 Gy in 39 fractions for prostate and seminal vesicles.

Dosimetric evaluation of irregular surface compensator and intensity-modulated radiotherapy in breast radiotherapy.

Background: This dosimetric study aims to evaluate the dosimetric advantage of the irregular surface compensator (ISC) compared with the intensity-modulated radiotherapy (IMRT).

Materials And Methods: Ten patients with whole breast irradiation were planned with the ISC and IMRT techniques. Six different beam directions were selected for IMRT and ISC plans.

Preoperative versus postoperative chemoradiotherapy for locally advanced rectal cancer: Outcomes of survival, toxicity, sphincter preserving and prognostic factors.

Background: This study aimed to compare preoperative chemoradiotherapy (CRT) with postoperative CRT regarding survival, local control, disease control, sphincter preservation, toxicity and also prognostic factors for the treatment of locally advanced rectal cancer.

Methods: Records of 140 patients with locally advanced rectal cancer who received preoperative or postoperative CRT were analyzed retrospectively. We compared the treatment groups (preoperative vs postoperative) according to baseline characteristics (demographic and rectal cancer disease characteristics), and also carried out the survival analyses.

Impact of different treatment plans on EQD for intracavitary brachytherapy of cervical cancer.

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

Locally advanced squamous cell cervical cancer in a patient with septate uterus.

A 33-year-old premenopausal multiparous woman with the history of septate uterus was referred to the hospital with menorrhagia and inter-menstrual bleeding occurring for the last 6 months. Work-up revealed a stage IIB cervical cancer. The patient underwent curative chemo/radiotherapy.
