Predicting Immunotherapy Efficacy from Analysis of Pre-treatment Tumor Biopsies

This study will establish a prospective cohort of pre-treatment tumor specimens with correlated de-identified clinical and demographic data and tissue histology from cancer patients who are undergoing treatment with PD-1/PD-L1 inhibitors. Patients who have undergone pre-anti-PD-1/PD-L1-treatment tumor biopsy or who are scheduled for tumor biopsy prior to anti-PD-1/PD-L1 treatment will be enrolled. The study will not require a study-specific tumor biopsy; any biopsies taken prior to treatment as part of standard of care are eligible for this study. Biopsies must not have been taken after immun…
