The dilemma of radiation necrosis from diagnosis to treatment in the management of brain metastases.

Radiation therapy with stereotactic radiosurgery (SRS) or whole brain radiation therapy is a mainstay of treatment for patients with brain metastases. The use of SRS in the management of brain metastases is becoming increasingly common and provides excellent local control. Cerebral radiation necrosis (RN) is a late complication of radiation treatment that can be seen months to years following treatment and is often indistinguishable from tumor progression on conventional imaging.

The role of targeted therapy and immune therapy in the management of non-small cell lung cancer brain metastases.

Brain metastases are a significant source of morbidity and mortality in patients with non-small cell lung cancer. Historically, surgery and radiation therapy have been essential to maintaining disease control within the central nervous system due to poorly penetrant conventional chemotherapy. With the advent of targeted therapy against actionable driver mutations, there is potential to control limited and asymptomatic intracranial disease and delay local therapy until progression.

10-Year Breast Cancer Outcomes in Women ≤35 Years of Age.

Purpose: Breast cancer diagnosis at a very young age has been independently correlated with worse outcomes. Appropriately intensifying treatment in these patients is warranted, even as we acknowledge the risks of potentially mutagenic adjuvant therapies. We examined local control, distant control, overall survival, and secondary malignancy rates by age cohort and by initial surgical strategy.

Radiation recall dermatitis after treatment of stage IV breast cancer with nivolumab: a case report.

Radiation recall dermatitis (RRD) is an uncommon dermatologic reaction provoked notably by chemotherapy in an area of skin irradiated weeks to years prior. We report a case of RRD with nivolumab in a woman with breast cancer. The patient was diagnosed with invasive ductal carcinoma of the left breast with an isolated spinal metastasis approached in an oligometastatic fashion with neoadjuvant chemotherapy, modified radical mastectomy and adjuvant radiotherapy.

A Current Review of Spatial Fractionation: Back to the Future?

Spatially fractionated radiation therapy represents a significant departure from canonical thinking in radiation oncology despite having origins in the early 1900s. The original and most common implementation of spatially fractionated radiation therapy uses commercially available blocks or multileaf collimators to deliver a nonconfluent, sieve-like pattern of radiation to the target volume in a nonuniform dose distribution. Dosimetrically, this is parameterized by the ratio of the valley dose in cold spots to the peak dose in hot spots, or the valley-to-peak dose ratio.
