The Role of Genomic Techniques in Predicting Response to Radiation Therapy

The understanding of the relationship between genetic variation and an individual patient ’s response to radiation therapy has gained significant ground over the past several years. Genetic markers have been identified that could ultimately serve as the foundation for predictive models in clinical practice, and that hold the potential to revolutionize the delivery of precision medicine in oncology.

AbstractBackgroundBleeding and obstruction are common localized symptoms in patients with unresectable gastric cancer. Although there are several reports about surgical and endoscopic therapies for gastric cancer, there are few regarding palliative radiation therapy.MethodsWe retrospectively analyzed data for 23 gastric cancer patients who underwent palliative radiation between April 2006 and March 2014, with either localized bleeding (n = 18) or upper gastric obstruction (n = 10).ResultsThe median (range) total dose and fraction (Fr) of radiotherapy (RT) were 42 (18 –60) Gy and 20 (9...

ConclusionsLittle is known about risk factors and pathogenesis of RIM. Here we describe the first case of RIM following immunotherapy. The diagnosis is based on clinical appearance and histopathological examination. Treatment should be initiated in the inflammatory stage in order to prevent or delay irreversible fibrosis and atrophy of the breast.

We report the case of a 61-year-old man presented with neurological and psychiatric manifestations following the radiation therapy for non-small cell lung carcinoma with brain metastasis. We have briefly reviewed and discussed the risk factors, clinical features, diagnostic, therapeutic, and preventive aspect of radiation-induced neuropsychiatric manifestations.

Abstract Breast-conserving surgery (BCS) followed by radiation therapy is the current standard of care for early stage breast cancer. Successful BCS necessitates complete tumor resection with clear margins at the pathologic assessment of the specimen ("no ink on tumor"). The presence of positive margins warrants additional surgery to obtain negative final margins, which has significant physical, psychological, and financial implications for the patient. The challenge lies in developing accurate real-time intraoperative margin assessment techniques to minimize the presence of "ink on tumor" and ...
