Multicenter Study Comparative StudyRadiation Therapy Versus No Radiation Therapy to the Neo-breast Following Skin-Sparing Mastectomy and Immediate Autologous Free Flap Reconstruction for Breast Cancer: Patient-Reported and Surgical Outcomes at 1 Year-A Mastectomy Reconstruction Outcomes Consortium (MROC) Substudy.
To determine whether adjuvant radiation therapy (RT) is associated with adverse patient-reported outcomes and surgical complications 1 year after skin-sparing mastectomy and immediate autologous free flap reconstruction for breast cancer. ⋯ RT to the neo-breast compared with no RT following immediate autologous free flap reconstruction for breast cancer is well tolerated at 1 year following surgery despite patients undergoing RT also having a higher cancer stage and more intensive surgical and systemic treatment. Neo-breast symptoms are more common in patients receiving RT by the EORTC Breast Cancer-Specific Quality of Life Questionnaire but not by the BREAST-Q. Patient-reported results at 1 year after surgery suggest RT following immediate autologous free flap breast reconstruction is well tolerated.

Multicenter Study Observational StudyA Multi-institutional Prospective Observational Study of Stereotactic Radiosurgery for Patients With Multiple Brain Metastases (JLGK0901 Study Update): Irradiation-related Complications and Long-term Maintenance of Mini-Mental State Examination Scores.
The JLGK0901 study showed the noninferiority of stereotactic radiosurgery (SRS) alone as initial treatment of 5 to 10 brain metastases (BMs) compared with 2 to 4 BMs in terms of overall survival and most secondary endpoints (Lancet Oncol 2014;15:387-95). However, observation periods were not long enough to allow confirmation of the long-term safety of SRS alone in patients with 5 to 10 BMs. ⋯ Neither MMSE score maintenance nor post-SRS complication incidence differed among groups A, B, and C. This longer-term follow-up study further supports the already-reported noninferiority hypothesis of SRS alone for patients with 5 to 10 BMs versus 2 to 4 BMs.

Multicenter StudyPhase 1 Study of Ipilimumab Combined With Whole Brain Radiation Therapy or Radiosurgery for Melanoma Patients With Brain Metastases.
We performed a phase 1 study to determine the maximum tolerable dose and safety of ipilimumab with stereotactic radiosurgery (SRS) or whole brain radiation therapy (WBRT) in patients with brain metastases from melanoma. ⋯ Concurrent ipilimumab 10 mg/kg with SRS is safe. The WBRT arm was closed early because of slow accrual but demonstrated safety with ipilimumab 3 mg/kg. No patient experienced dose-limiting toxicity. Larger studies, including those with combination checkpoint inhibitor therapy and SRS, are warranted.
