Radiotherapy Results in Locally Advanced Sinonasal Cancer: Turkish Society for Radiation Oncology, Head and Neck Study Group 01-005.

Objectives: This study aims to examine the treatment outcomes and related factors in locally advanced sinonasal cancer across Turkiye.

Methods: Twelve centers participants of the Turkish Society for Radiation Oncology Head and Neck Study Group attended the study. One hundred and ninety-four patients treated with intensity-modulated radiation therapy between 2001 and 2021 were analyzed retrospectively.

Surgical Management of Brain Tumors in Infants Under One Year of Age.

Aim: To comprehensively analyze clinical presentation, diagnosis, and management approaches of brain tumors in infants under one year of age.

Material And Methods: We conducted a retrospective analysis of clinical data retrieved from medical records of infants who underwent surgical treatment for intracranial mass lesions at our institution from January 2006 to December 2016. The data encompassed parameters such as age at diagnosis, symptoms, tumor location, histology, surgical procedures, adjuvant treatment, and survival outcomes.

A multicenter retrospective analysis of patients with nasopharyngeal carcinoma treated in IMRT era from a nonendemic population: Turkish Society for Radiation Oncology Head and Neck Cancer Group Study (TROD 01-001).

Background: We aimed to evaluate patients with nasopharyngeal carcinoma (NPC) in a nonendemic population.

Methods: In a national, retrospective, multicenteric study, 563 patients treated with intensity modulated radiotherapy at 22 centers between 2015 and 2020 were analyzed.

Results: Median age was 48 (9-83), age distribution was bimodal, 74.

Improving locoregional outcome in high-intermediate-risk and high-risk stage I endometrial cancer with surgical staging followed by brachytherapy.

Purpose: This study aims to assess the locoregional efficacy of postoperative vaginal brachytherapy (VBT) alone in patients undergoing surgical staging for early-stage high-intermediate-risk (HIR) and high-risk (HR) endometrial cancer.

Materials And Methods: One hundred and four patients with early-stage HIR and HR endometrial cancer who underwent surgical staging were treated with adjuvant VBT alone. The patients with stage Ib, grade I-III, stage Ia, grade III, lower uterine segment involvement, and lymphovascular invasion (LVI) were included to study.

ESTRO ACROP and SIOPE recommendations for myeloablative Total Body Irradiation in children.

Background And Purpose: Myeloablative Total Body Irradiation (TBI) is an important modality in conditioning for allogeneic hematopoietic stem cell transplantation (HSCT), especially in children with high-risk acute lymphoblastic leukemia (ALL). TBI practices are heterogeneous and institution-specific. Since TBI is associated with multiple late adverse effects, recommendations may help to standardize practices and improve the outcome versus toxicity ratio for children.

Increased radiosensitivity and impaired DNA repair in patients with STAT3-LOF and ZNF341 deficiency, potentially contributing to malignant transformations.

STAT3 plays an important role in various complex and sometimes contradictory pathways such as proliferation, differentiation, migration, inflammation, and apoptosis. The transcriptional activity of the STAT3 gene is controlled by a transcription factor called ZNF341. There is insufficient data on radiation sensitivity and post-radiation DNA repair in STAT3- loss-of-function (LOF) patients.

Why do some patients with stage 1A and 1B endometrial endometrioid carcinoma experience recurrence? A retrospective study in search of prognostic factors.

Objectives: Endometrial endometrioid carcinoma (EEC) is the most encountered subtype of endometrial cancer (EC). Our study aimed to investigate the factors affecting recurrence in patients with stage 1A and 1B EEC.

Material And Methods: Our study included 284 patients diagnosed with the International Federation of Gynecology and Obstetrics stage 1A/1B EEC in our center from 2010 to 2018.

Towards homogenization of total body irradiation practices in pediatric patients across SIOPE affiliated centers. A survey by the SIOPE radiation oncology working group.

Background And Purpose: To reduce relapse risk, Total Body Irradiation (TBI) is part of conditioning regimens for hematopoietic stem cell transplantation (HSCT) in pediatric acute leukemia. The study purpose was to evaluate clinical practices regarding TBI, such as fractionation, organ shielding and delivery techniques, among SIOPE affiliated radiotherapy centers.

Methods: An electronic survey was sent out to 233 SIOPE affiliated centers, containing 57 questions about clinical practice of TBI.

Transforming growth factor-β1 gene polymorphism as a potential risk factor in Turkish patients with laryngeal squamous cell carcinoma.

Introduction: Laryngeal cancer is the most common head-and-neck malignancies with more than 20% of all cases. The vast majority of tumors are squamous cell carcinoma (SCC). Several genes encoding different cytokines may play crucial roles in host susceptibility to cancer because cytokine production capacity varies among individuals and depends on cytokine gene polymorphisms.

Evaluation of late effects of postoperative radiotherapy in patients with medulloblastoma.

We aimed to evaluate long-term toxicity in children with medulloblastoma treated with postoperative radiotherapy (RT). This study included 21 patients aged 4-16 who had been diagnosed with medulloblastoma. All of the patients in the study received postoperative craniospinal RT.

Role of PET/CT in treatment planning for head and neck cancer patients undergoing definitive radiotherapy.

Background: In this study, we aimed to investigate the benefits of 18F-deoxyglucose positron emission tomography/computed tomography (FGD-PET/CT) imaging for staging and radiotherapy planning in patients with head and neck cancer undergoing definitive radiotherapy.

Materials And Methods: Thirty-seven head and neck cancer patients who had undergone definitive radiotherapy and PET/CT at the Uludag University Medical Faculty Department of Radiation Oncology were investigated in order to determine the role of PET/CT in staging and radiotherapy planning.

Results: The median age of this patient group of 32 males and 5 females was 57 years (13-84years).

[Our results of postoperative radiation therapy in patients with salivary gland cancer].

Objectives: This study aims to evaluate our single center experience in patients with a salivary gland tumor receiving postoperative radiation therapy (RT).

Patients And Methods: Between January 1996 and December 2011, the records of 34 salivary gland tumor patients who were operated and referred to our clinic for adjuvant RT were retrospectively analyzed. Radiation therapy was applied to the primary tumor and lymphatics at a median dose of 60 Gy (54 to 60 Gy) with 1.

The evaluation of bcl-2 expression as a prognostic marker in early stage laryngeal cancer.

Aims And Background: To evaluate the effect of bcl-2 expression on the local control and overall survival of patients with early stage laryngeal cancer treated with radiotherapy alone.

Methods And Study Design: We included 53 patients with stage Tis, T1, and T2 laryngeal cancer who were irradiated in our department. Paraffin blocks of all biopsy specimens were subjected to immunohistochemical analysis with a bcl-2 oncoprotein mouse clone 124 Scytek kit.
