Rheumatologic immune checkpoint inhibitor-related adverse events.

PURPOSE OF REVIEW: Immune check point inhibitors (ICIs) are a unique class of cancer treatments that harness the body's innate antitumor response. Although these medications have transformed oncology care, they also lead to generalized immune activation that can result in toxicities across a spectrum of organ systems called immune-related adverse events. This article reviews the most common rheumatologic immune-related adverse events and their management. RECENT FINDINGS: Inflammatory arthritis, polymyalgia rheumatic, sicca symptoms, systemic sclerosis, myositis, and vasculitis have all been reported as ICI adverse events. Treatment includes nonsteroidal anti-inflammatory drugs, glucocorticoids, traditional DMARDs, and biologics. SUMMARY: Rheumatologists have an important role in the management of patients with rheumatologic immune-related adverse events. Working with our oncology colleagues, we can help manage rheumatologic immune-related adverse events while optimally preserving ICI's antitumor effects.

Perioperative Therapy for Surgically Resectable Pancreatic Adenocarcinoma.

It is estimated that 10% to 20% of patients with pancreatic cancer present with resectable disease. Although surgery offers curative intent, the median survival after curative resection is less than 2 years. To improve clinical outcomes in this patient population, clinical studies have investigated the role of perioperative therapy, including neoadjuvant and adjuvant treatment in resectable pancreatic cancer. The role of adjuvant therapy has been well established by large randomized phase III studies, whereas benefit of the neoadjuvant approach remains inconclusive. Here, we review various treatment modalities and their clinical benefits in resectable pancreatic cancer.

A phase II trial of intrapatient dose-escalated sorafenib in patients with metastatic renal cell carcinoma.

PURPOSE: Sorafenib has been demonstrated as second-line therapy, with limited significant adverse events at a dose of 400 mg twice a day (b.i.d.) in patients with metastatic renal cell carcinoma. This study evaluated the ability of patients to dose-escalate, response rate, progression-free survival (PFS), and overall survival. METHODS: The initial dose of sorafenib was 400 mg b.i.d.. Dose escalation of sorafenib to 600 mg b.i.d. occurred from days 29-56 and increased to 800 mg b.i.d. on day 57 and beyond as tolerated. Dose modifications were performed for toxicity per the National Cancer Institute Common Toxicity Criteria version 3.0. The patients were evaluated every 2 cycles (8 weeks) by using Response Evaluation Criteria in Solid Tumors version 1.0. RESULTS: Forty-four patients were evaluable for response. Median age was 62.5 years, 39 patients had a Karnofsky Perfomance Status of 100%. Twenty-two patients received no prior therapy. Of the evaluable patients, 42 were dose escalated to 600 mg b.i.d., and 74% (31) of these were further dose escalated to 800 mg b.i.d.. Eight patients had a complete response (CR), 13 patients demonstrated a partial response (PR), and 21 patients had stable disease. Common treatment-related adverse events included hypertension, hand-foot syndrome, skin rash, diarrhea, dry skin, alopecia, and facial redness. DISCUSSION: The majority of patients were escalated to 600 mg b.i.d. or 800 mg b.i.d.. Intrapatient dose-escalated sorafenib has promising antitumor activity as demonstrated by a 48% CR-PR rate (21 patients). Antitumor activity is further suggested by a prolonged PFS ≥6 months in 64% (28) of patients. Significant antitumor activity and reversible adverse events has been demonstrated in escalated doses of sorafenib.
