RESUMEN
Immunotherapy has revolutionized the treatment paradigm of non-small cell lung cancer and improved patients' prognosis. Immune checkpoint inhibitors have quickly become standard frontline treatment for metastatic non-oncogene addicted disease, either as a single agent or in combination strategies. However, only a few patients have long-term benefits, and most of them do not respond or develop progressive disease during treatment. Thus, the identification of reliable predictive and prognostic biomarkers remains crucial for patient selection and guiding therapeutic choices. In this review, we provide an overview of the current strategies, highlighting the main clinical challenges and novel potential biomarkers.

BACKGROUND: Obesity is associated with an increased risk of development and recurrence of colorectal cancer. The role of obesity in metastatic colorectal cancer patients (pts) is still unclear, especially in those treated with triplet plus bevacizumab (bev). The aim of our study was to evaluate the prognostic and predictive role of BMI in metastatic colorectal cancer pts treated with FOLFOXIRI plus bev or FOLFIRI/FOLFOX plus bev in the TRIBE and TRIBE-2 trial. MATERIALS AND METHODS: A total of 1160 pts enrolled in TRIBE and TRIBE-2 trials were included. Baseline height and weight were used to assign pts to one of the following BMI categories: underweight (group A = BMI <18.5 kg/m2; 52 pts), normal (group B = BMI 18.5-29.9 kg/m2; 952 pts) and obese (group C > 30 kg/m2; 156 pts). RESULTS: In our population, no differences in terms of PFS (P = .43) or OS (P = .99) resulted between 3 groups. No interaction effect between treatment arm and BMI was evident in terms of PFS (Group A HR: 0.65 [95%CI: 0.36-1.16]; Group B HR: 0.77 [95%CI: 0.67-0.88]; Group C HR: 0.67 [95%CI: 0.48-0.93]; P for interaction = .75) or OS (Group A HR: 0.57 [95%CI: 0.29-1.12]; Group B HR: 0.85 [95%CI: 0.73-0.99];Group C HR: 0.69 [95%CI: 0.48-1.01] P for interaction = .36). No statistically significant difference in terms of dose reductions due to toxicities were found according to BMI in the overall population (P = .48) and in pts treated with FOLFOXIRI plus bev (P = .57). CONCLUSION: BMI was neither prognostic or predictive for PFS and OS in our population. Our analyses showed that the advantage of FOLFOXIRI plus bev versus FOLFIRI/FOLFOX plus bev was independent from BMI.

Cancer immunotherapy has become a stronghold in modern oncology. Immune checkpoint inhibitors, in particular anti-PD-1 and anti-PD-L1 antibodies, are approved for the treatment of several solid cancers. In the near future, an increasing number of patients will be eligible for immunotherapy. Therefore, the management of immune-related adverse events is a daily challenge in clinical practice, among which hepatic immune-related toxicity has been described as a rare adverse event. We report the case of a patient treated with nivolumab (an anti-PD-L1 antibody) for a stage IV resected melanoma who developed recurrence of steroid-refractory liver toxicity that was later discovered to be associated with acute exacerbation of chronic undiagnosed hepatitis B. The patient significantly benefited from antiviral treatment. We conclude that serological viral screening is strongly recommended before starting immune checkpoint inhibitor treatment.
