BACKGROUND: For inpatients with metastatic intracranial disease burden exceeding established guidelines for stereotactic radiosurgery (SRS), the standard of care involves whole brain radiation therapy (WBRT), typically administered as a 2-week course of treatment with biologically effective dose (BED) of 60 Gy. However, shorter course WBRT provides theoretical advantages in quality of life and decreasing systemic therapy delay. This retrospective study evaluates our early experience with BED-comparable short-course WBRT (23 Gy in 5 fractions; BED=58...

Early gastric cancer (EGC) refers to malignant tumor lesions that are limited to the mucosa and submucosa layers, regardless of the presence of lymph node metastasis. Typically, EGC has a low rate of perigastric lymph node metastasis, and long-term survival outcomes are good after radical surgical treatment. The primary objective of surgical treatment for EGC is to achieve functional preservation while ensuring a radical cure. Sentinel node navigation surgery (SNNS) is a surgical technique used in the treatment of EGC...

Retroperitoneal tumors (RPTs) encompass both benign and malignant entities, constituting ~0.1% to 0.2% of all malignant tumors, of which 70% to 80% manifest malignancy. Predominantly, retroperitoneal sarcomas (RPS) represent the most prevalent subtype among RPT. With over 70 histologic forms identified, liposarcomas and leiomyosarcomas emerge as the primary constituents of RPS. Accurate diagnosis of RPTs necessitates preoperative core-needle biopsy and comprehensive imaging assessment. The current staging protocol for RPS relies on the eighth edition of the American Joint Committee on Cancer/TNM classification...

INTRODUCTION: Spinal metastases are common in metastatic cancer, affecting around 40% of patients. The primary treatment involves radiation therapy, transitioning from conventional external beam radiation therapy (EBRT) to stereotactic body radiation therapy (SBRT) for its superior, durable response. While spine SBRT has gained popularity in the United States, Level I evidence supporting it over EBRT is limited to a Canadian trial using a 2-fraction SBRT regimen. We present our findings from one of the earliest US experiences of 2-fraction spine SBRT for spinal metastases...

BACKGROUND: Androgen receptor-targeted therapies (ARTs) improve survival outcomes in patients with metastatic castration-resistant prostate cancer (mCRPC); however, a significant portion of patients discontinue treatment for various reasons including treatment-related toxicity. We aim to describe reasons for ART treatment discontinuation and identify predictors associated with increased risk of treatment discontinuation due to toxicity. METHODS: We performed a single-institution retrospective review of patients with mCRPC receiving ART between 2010 and 2021...

OBJECTIVE: Glioblastoma (GBM) is a fatal adult central nervous system tumor. Due to its high heterogeneity, the survival rate and prognosis of patients are poor. Thousands of people die of this disease every year all over the world. At present, the treatment of GBM is mainly through surgical resection and the combination of later drugs, radiotherapy, and chemotherapy. An abnormal redox system is involved in the malignant progression and treatment tolerance of glioma, which is the main reason for poor survival and prognosis...

OBJECTIVE: The safety of single-treatment stereotactic radiosurgery (SRS) for vestibular schwannoma (VS) with radiographic evidence of brainstem compression but without motor deficit is controversial. Data on linear accelerator (linac)-based SRS in this setting are scarce. We address this with an outcomes report from an unselected series of patients with VS with radiographic brainstem compression treated with linac SRS. METHODS: We included 139 patients with unilateral VS (any size) with radiographic brainstem compression (all without serious brainstem neurological deficits)...

INTRODUCTION: The role of internal mammary nodal irradiation (IMNI) as a component of regional nodal radiotherapy is a controversial issue in breast radiation oncology with conflicting results presented in recent landmark trials. We thus created a meta-analysis of available data to better ascertain the potential benefit of IMNI. We hypothesize that with the increased power available within a meta-analysis, IMNI will prove to improve overall survival (OS) in breast cancer. METHODS: Literature search was conducted for prospective studies comparing IMNI to no IMNI...

BACKGROUND: Triple-negative breast cancer (TNBC) is a subtype of breast cancer characterized by the absence of expression of estrogen receptor, progesterone receptor, or human epidermal growth factor receptor 2. This subtype of breast cancer is known for its high aggressiveness, high metastatic potential, tendency for recurrence, and poor prognosis. Patients with metastatic TNBC (mTNBC) have a poorer prognosis and a higher likelihood of early death (survival time ≤3 months). Therefore, the development of effective individualized survival prediction tools, such as prediction nomograms and web-based survival calculators, is of great importance for predicting the probability of early death in patients with metastatic TNBC...
