Phase 1 Study of Ipilimumab Combined With Whole Brain Radiation Therapy or Radiosurgery for Melanoma Patients With Brain Metastases.

PURPOSE: 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. METHODS AND MATERIALS: Based on the intracranial disease burden, patients underwent WBRT (arm A) or SRS (arm B). The ipilimumab starting dose was 3 mg/kg every 3 weeks, starting on day 3 of WBRT or 2 days after SRS. The ipilimumab dose was escalated to 10 mg/kg using a 2-stage, 3+3 design. The primary endpoint was to determine the maximum tolerable dose of ipilimumab combined with radiation therapy. The secondary endpoints were overall survival, intracranial and extracranial control, progression-free survival, and toxicity. The ClinicalTrials.gov registration number is NCT01703507. RESULTS: The characteristics of the 16 patients enrolled between 2011 and 2014 were mean age, 60 years; median number of brain metastases, 2 (range 1->10); and number with EC disease, 13 (81%). Treatment included WBRT (n=5), SRS (n=11), and ipilimumab 3 mg/kg (n=7) or 10 mg/kg (n=9). The median follow-up was 8 months (arm A) and 10.5 months (arm B). A total of 21 grade 1 to 2 neurotoxic effects occurred, with no dose-limiting toxicities. One patient experienced grade 3 neurotoxicity before ipilimumab administration. Ten additional grade 3 toxicities were reported, with gastrointestinal toxicities (n=5; 31%) the most common. No patient developed grade 4 or 5 toxicity. The median progression-free survival and overall survival in arm A was 2.5 months and 8 months and in arm B was 2.1 months and not reached, respectively. CONCLUSIONS: 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.

Management of postmenopausal symptoms in breast cancer survivors.

With the increasing numbers of breast cancers survivors, menopause, its symptoms, and its physical complications are becoming more prevalent problems in this patient population. Hormonal replacement, which has been the cornerstone therapy of menopausal related symptoms for decades, recently has been shown to increase breast cancer incidence as well as risk of recurrence and no longer should be recommended. Menopausal symptoms and complications such as hot flashes, vaginal dryness, dyspareunia, and osteoporosis leading to fractures have a negative impact on the quality of life of both breast cancer survivors and the general postmenopausal population. The purpose of this review is to discuss the evidence for the use of alternative therapies for menopausal symptoms, thus providing guidance and recommendations that should facilitate therapeutic decisions in the daily practice of medical oncologists and primary care physicians.

Intralesional therapy for in-transit and satellite metastases in melanoma.

Intratumoral therapy with bacteria/bacterial products dates to at least the 1890s. Over the decades this has expanded beyond the use of microbes and microbial products to include chemicals, cancer chemotherapeutic agents, cytokines, recombinant organisms, and hybrid molecules. The appeal of this method of delivery is the ability to deliver high concentrations of the therapeutic agent directly to the tumor, often with minimal side effects. This article summarizes the use and efficacy of the various agents used in the past and present in the treatment of in-transit and satellite metastases in melanoma.
