OBJECTIVE The JLGK0901 study found that stereotactic radiosurgery (SRS) is a safe and effective treatment option for treating up to 10 brain metastases. The purpose of this study is to determine the cost-effectiveness of treating up to 10 brain metastases with SRS, whole-brain radiation therapy (WBRT), or SRS and immediate WBRT (SRS+WBRT). METHODS A Markov model was developed to evaluate the cost effectiveness of SRS, WBRT, and SRS+WBRT in patients with 1 or 2-10 brain metastases. Transition probabilities were derived from the JLGK0901 study and modified according to the recurrence rates observed in the Radiation Therapy Oncology Group (RTOG) 9508 and European Organization for Research and Treatment of Cancer (EORTC) 22952-26001 studies to simulate the outcomes for patients who receive WBRT...

BACKGROUND: Whole brain radiotherapy (WBRT) and stereotactic radiosurgery were frequently used to palliate patients with brain metastases. It remains controversial which modality or combination of therapy is superior especially in the setting of limited number of brain metastases. The availability of newer medical therapy that improves survival highlighted the importance of reducing long term radiation toxicity associated with WBRT. In this study, we aim to demonstrate the hippocampal sparing technique with whole brain and integrated simultaneous boost Materials and Methods: Planning data from 10 patients with 1-5 brain metastases treated with SRS were identified...

BACKGROUND: A commonly employed treatment for advanced staged oropharyngeal squamous cell carcinoma (OPSCC) is concurrent radiation and chemotherapy with cisplatin as the gold standard. Carboplatin is reported to have the same radiopotentiation properties and a superior side effect profile; however, its use in head and neck cancer has been limited due to the paucity of data and reported hematologic side effects. In this study, we describe our institution's experience with carboplatin, paclitaxel and radiation in the treatment of oropharyngeal squamous cell carcinoma over a 10 year period...

A number of promising new approaches for both local and systemic control of locally advanced non-small cell lung cancer have been examined in clinical trials, aimed at improving the patient survival. Development of better systemic therapies by adopting newer agents (such as epidermal growth factor receptor-tyrosine kinase inhibitors and immune checkpoint inhibitors) from advanced non-small cell lung cancer is mandatory. As for radiotherapy, adaptive radiotherapy and proton therapy are under investigation after the RTOG 0617 trial unexpectedly failed to show the efficacy of high-dose radiotherapy for Stage III disease...
