Purpose: Retroperitoneal sarcomas (RPS) are rare tumors that present unique challenges, often due to late presentation, and the proximity of critical organs makes complete surgical resection challenging. This study aimed to assess the feasibility of neoadjuvant short-course radi...
Purpose: No guidelines exist to delineate radiation therapy (RT) targets for the treatment of multiple glioblastoma (mGBM). This study analyzes margins around the gross tumor volume (GTV) to create a clinical target volume (CTV), comparing response parameters and modalities of r...
Purpose: Implementing intensity-modulated brachytherapy (IMBT) techniques with high-energy sources like 60Co has always been challenging due to the clinical limitations of the applicator dimensions. This study aims to investigate using tungsten trioxide nanoparticles/epoxy compo...
Purpose: This study aimed to investigate the risk factors and predictive value of vertebral Hounsfield units (HUs) for vertebral compression fracture (VCF) development in gastric cancer (GC) patients who received adjuvant radiotherapy (RT).
Materials and Methods: We retrospecti...
Purpose: This study aimed to investigate changes in target coverage using magnetic resonance–guided online adaptive radiotherapy (MRgoART) for kidney tumors and to evaluate the suitable timing of treatment.
Materials and Methods: Among patients treated with 3-fraction MRgoART ...
This study aimed to evaluate the long-term efficacy and complication of radiotherapy for benign soft tissue tumors. Five cases of benign soft tissue tumors (two plexiform neurofibromas, two juvenile nasopharyngeal angiofibromas, and one cavernous sinus hemangioma) who underwent ...

Purpose: High-dose-rate (HDR) brachytherapy is a promising treatment modality for organ and function preservation in lip and oral cavity cancers. This study aims to describe the technique and assess clinical outcomes of HDR interstitial brachytherapy in patients diagnosed with lip and buccal mucosa cancer treated in a comprehensive cancer center.
Materials and Methods: We conducted a retrospective analysis of six lip...

Purpose
This study evaluated interfractional bladder volume variations and the resulting dosimetric changes during short-course radiotherapy (SCRT) 5X5Gy (RBE) in patients with locally advanced rectal cancer.
Materials and methods
Twenty patients received either protons or photons with daily cone-beam CT (CBCT). All patients received the same drinking instructions prior to the planning CT and each fraction. For each patient, VMAT and PBT plans...

This study evaluates the use of magnetic resonance–guided radiation therapy (MRgRT) as an alternative to brachytherapy in treating para-urethral gynecological cancers, particularly for patients who are not candidates for brachytherapy. Five female patients with advanced para-urethral gynecological cancers underwent MRgRT using a custom 3-dimensional-printed intravaginal cylinder for image registration and treatment alignment. MRgRT was administered as a five-fraction adaptive boost...

Radiation-induced cutaneous side effects are well known; however, the isoradiotopic phenomenon presenting as lichen planus is underreported in the literature. It is imperative to be aware of this entity to manage the patients accordingly. Herein, we report a 31-year-old male, a known case of carcinoma glottis who developed lichen planus confined to the radiation site and presented with a review...

Purpose: This study aimed to evaluate the effect of radiotherapy (RT) on symptomatic relief and tumor control in patients with breast cancer with skin involvement.
Materials and Methods: This retrospective study included patients who received palliative RT of the breast or chest wall for breast cancer with skin involvement. Progression-free survival, freedom from local progression (FFLP), and symptomatic response were evaluated....

Purpose: Stereotactic radiotherapy (SRT) is an important adjunctive treatment after excision of brain metastases. We investigated efficacy and safety outcomes of such treatment and the impact of radiotherapy dose fractionations in a real-world multi-center cohort.
Materials and Methods: All patients who received resection cavity SRT between 2018–2022 were identified from institutional databases of two tertiary oncology centers. Patient and treatment characteristics...
