Pedro Barata, MD, MSc, discusses important considerations regarding the relationship between immunotherapy treatment and the gut microbiome when treating patients with kidney cancer.

The combination of pembrolizumab and lenvatinib demonstrated a statistically significant improvement in progression-free survival and objective response rate but failed to improve overall survival compared with pembrolizumab plus placebo as frontline therapy for patients with recurrent or metastatic head and neck squamous cell carcinoma.

The combination of cabozantinib and atezolizumab led to a statistically significant improvement in progression-free survival compared with a second novel hormonal therapy in patients with metastatic castration-resistant prostate cancer and measurable soft tissue disease following 1 prior novel hormonal therapy, meeting one of the primary end points in the primary analysis of the phase 3 CONTACT-02 trial.

Patients with mismatch repair–deficient and/or microsatellite instability metastatic colorectal cancer experienced a progression-free survival benefit with longer disease control following treatment with avelumab compared with standard second-line chemotherapy.
