Radiotherapy for benign diseases in Turkey: a patterns of care survey of the Turkish Society for Radiation Oncology (TROD 05-002).

Purpose: We aimed to investigate the patterns of radiotherapy (RT) care in cases of benign diseases in Turkey.

Methods: A questionnaire survey was sent to all radiation oncology (RO) departments in Turkey. The number of patients treated for benign disease between 2015 and 2020 was requested.

Ninety-degree angled collimator: a dosimetric study related to dynamic intensity-modulated radiotherapy in patients with endometrial carcinoma.

Background: Our purpose was to ensure that the dose constraints of the organs at risk (OARs) were not exceeded while increasing the prescription dose to the planning target volume (PTV) from 45 to 50.4 Gray (Gy) with the dynamic intensity-modulated radiotherapy (IMRT) technique. While trying for this purpose, a new dynamic IMRT technique named 90° angled collimated dynamic IMRT (A-IMRT) planning was developed by us.

Outcomes of carotid sparing intensity-modulated radiotherapy for early stage glottic cancer in 201 patients: Multicenter study of Turkish Radiation Oncology Society/TROD-01-007.

Background: To assess and report clinical outcomes after carotid sparing intensity-modulated radiotherapy for early stage laryngeal cancer.

Methods: We retrospectively analyzed 201 patients with early stage glottic laryngeal cancer treated with carotid sparing intensity-modulated radiotherapy (IMRT)/volumetric modulated arc therapy (VMAT) techniques in six TROD centers.

Results: After a median follow-up of 31 months the actuarial 1- and 3-year local and locoregional control rates were 99.

Radical radiotherapy in patients with cervix uteri carcinoma: experience of Ondokuz Mayis University.

Background: Radical radiotherapy is the standard treatment for patients with locally advanced cervix uteri carcinoma (FIGO stage IB2-IVA). Worldwide, incidence and mortality rates vary among regions because of differences in lifestyles and treatment standards. Herein, we evaluated the outcomes of radical radiotherapy in patients with locally advanced cervix uteri carcinoma from the middle Black Sea region of Turkey.

Dosimetric Comparison of Three Different Radiotherapy Techniques in Antrum-Located Stomach Cancer.

Background: The current optimal radiotherapy (RT) planning technique for stomach cancer is controversial. The design of RT for stomach cancer is difficult and differs according to tumor localization. Dosimetric and clinical studies have been performed in patients with different tumor localizations.

Male Breast Cancer: 20 Years Experience of a Tertiary Hospital from the Middle Black Sea Region of Turkey.

Background: Male breast cancer is a rare neoplasm, and its treatments are based on those of female breast cancer. This study aimed to analyze 20 years of male breast cancer clinical characteristics and treatment results from the Middle Black Sea Region of Turkey.

Materials And Methods: A retrospective analysis of 16 male breast cancer patients treated in our tertiary hospital between 1994 and 2014 was performed.

Radiation-associated secondary brain tumors after conventional radiotherapy and radiosurgery.

Although there is not enough strong molecular evidence for radiation to be a causal factor for the development of secondary brain tumors, a relationship has still been found. There is a slight but significant 2-2.7% increased risk of secondary brain tumors after conventional radiotherapy.

Prognostic significance of concomitant radiotherapy in newly diagnosed glioblastoma multiforme: a multivariate analysis of 116 patients.

Background And Objectives: Currently, radiotherapy with concomitant and adjuvant temozolomide has become the standard treatment for glioblastoma. The purpose of this study was to report our experience with radiation plus concomitant temozolomide in 116 patients with glioblastoma multiforme (GBM) and examine the value of different prognostic factors.

Design And Setting: Retrospective analysis of 116 patients with newly diagnosed GBM, who were treated at our department between January 1994 and March 2009.

Fine-needle aspiration cytology of metastatic oligodendroglioma: case report and literature review.

Background: Systemic metastasis of a glial tumor is a rare event. However, metastatic cases are anticipated to increase due to prolongation of survival as a result of the development of new treatment modalities. The possibility of metastasis should be considered in patients with a history of a glial tumor rather than a second primary tumor.

Dosimetric comparison of three different external beam whole breast irradiation techniques.

Introduction: The purpose of this study was to compare the dosimetries of three different external beam whole breast radiotherapy techniques: two-dimensional RT (2D-RT), three-dimensional conformal RT (3D-CRT), and field-in-field intensity-modulated RT (FiF-IMRT). In addition, we aimed to evaluate the patients who needed more or less complex treatment modalities.

Methods: Thirty patients were included in the study.

The sequencing of radiation therapy and chemotherapy after mastectomy in premenopausal women with breast cancer.

Objective: The purpose of this study was to evaluate the prognostic importance of the sequencing of radiation therapy and chemotherapy after mastectomy in high-risk premenopausal women with breast cancer in addition to other known prognostic factors in the literature.

Methods: In this retrospective study, 176 premenopausal women with breast cancer were evaluated. The median age at referral was 39 years (range, 28-59 years); 106 patients had stage II and 70 had stage III disease.
