In this paper, we review the use of hypofractionated radiotherapy for gastrointestinal malignancies, focusing on primary and metastatic liver cancer, and recurrent rectal cancer. Technological advancements in radiotherapy have facilitated the direct delivery of high-dose radiation to tumors, while limiting normal tissue exposure, supporting the use of hypofractionation. Hypofractionated radiotherapy is particularly effective for primary and metastatic liver cancer where...

Purpose: Cervical cancer is a significant global health issue affecting approximately 600,000 women each year. This study aimed to address the knowledge gaps surrounding the influence of treatment time parameters, including the duration of external beam radiotherapy (EBRT) to brachytherapy and overall treatment duration, on early recurrences. Materials and Methods: Details on demographics, tumor characteristics, treatment details, and outcomes in patients...

Purpose: Neoadjuvant radiotherapy (RT) or chemoradiotherapy (CRT) is the standard treatment for locally advanced rectal adenocarcinoma. The recent emerging data on preoperative immunotherapy as an effective therapeutic modality for mismatch repair deficient rectal carcinomas suggests that the immune system plays a significant role in tumor eradication. Although RT has been shown to stimulate anti-tumor immunity, it also leads to substantial...

Purpose: Treatment outcomes of locally advanced rectal cancer have improved significantly in recent decades. This retrospective study aimed to assess the efficacy of neoadjuvant chemoradiotherapy (nCRT) followed by surgery in patients with T4 rectal cancer and the different outcomes between T4a and T4b patients. Materials and Methods: A total of 60 clinically T4 rectal cancer patients who underwent nCRT were...

Purpose: Identifying comprehensively the evidence of neuroprotective effects of memantine for preserving cognitive function in brain metastasis patients receiving whole brain radiotherapy (WBRT). Methods: We searched randomized clinical trials (RCTs) analyzing the effects of memantine to preserve cognitive function in patients with brain metastasis treated with WBRT, performed in some databases, including PubMed, Embase, and Cochrane Library. The protocol was registered...

Purpose: This report offers a detailed examination of the inception and current state of the Heavy-ion Therapy Center (HITC) at the Yonsei Cancer Center (YCC), setting it apart as the world’s first center equipped with a fixed beam and two superconducting gantries for carbon-ion radiation therapy (CIRT). Materials and Methods: Preparations for CIRT at YCC began in 2013; accordingly, this...

Purpose: After primary systemic therapy (PST), agreement on the extent of locoregional therapy is lacking in breast cancer patients who convert from a node-positive to a node-negative status. The aim of this survey was to investigate radiation therapy approaches after PST according to different axillary surgical strategies and disease responses. Material and Methods: The European Breast Cancer Research Association of Surgical...

Purpose: Cardiac radioablation is a novel, non-invasive treatment for ventricular tachycardia (VT), involving a single fractional stereotactic ablative body radiotherapy (SABR) session with a prescribed dose of 25 Gy. This complex procedure requires a detailed workflow and stringent dose constraints compared to conventional radiation therapy. This study aims to establish a consistent institutional workflow for single-fraction cardiac VT-SABR, emphasizing robust...

Cardiac myxomas, the most common primary cardiac tumors, are believed to originate from multipotent mesenchymal cells. Approximately 75% of myxomas occur within the left atrium, increasing the risk of systemic thromboembolic events. While typically benign, atrial myxomas can rarely metastasize to the brain, with fewer than 60 cases reported. We present a case of a 56-year-old woman with a history...
