Real-world experience with elective discontinuation of PD-1 inhibitors at 1 year in patients with metastatic melanoma.

Background: Randomized trials evaluating programmed cell death protein 1 (PD-1) inhibitors in metastatic melanoma either permitted treatment for 2 years (pembrolizumab) or more (nivolumab). The optimal duration of therapy is currently unknown due to limited data, and shorter therapies may be effective.

Methods: Data of patients with metastatic cutaneous melanoma treated with single-agent PD-1 inhibitors at Huntsman Cancer Institute from January 1, 2015, to December 31, 2018, was reviewed to identify a continuous series of patients who made the joint decision with their provider to electively discontinue therapy at 1 year (>6 months and <18 months) in the setting of ongoing treatment response or disease stability.

Case report: pembrolizumab-induced Type 1 diabetes in a patient with metastatic cholangiocarcinoma.

Background: Immune checkpoint inhibitors are novel cancer therapies associated with numerous autoimmune toxicities, some of which are only now being appreciated.

Case Presentation: A 67-year old female with metastatic cholangiocarcinoma and no prior history of diabetes was treated with leucovorin, fluorouracil, oxaliplatin and pembrolizumab. After eight cycles, she developed new onset type 1 diabetes mellitus with positive glutamic acid decarboxylase antibody titers.

What Is Optimal Front-Line Therapy for Chronic Lymphocytic Leukemia in 2017?

The front-line management of patients with chronic lymphocytic leukemia (CLL) has evolved significantly in recent years due to introduction of novel, targeted agents. Upon CLL diagnosis, physicians should determine whether treatment or careful observation is indicated. Once treatment is required, choice of therapy should be based on the age and fitness of the patient and the distinct molecular profile of their disease.
