Abstract:
BACKGROUND:A rapid progression pattern called hyperprogressive disease (HPD) has been observed during early cycles of programmed cell death protein 1 (PD-1)/programmed death-ligand 1 (PD-L1) inhibitor therapy. Data regarding HPD in patients with genitourinary cancer are limited. PATIENTS AND METHODS:We included 203 patients with genitourinary cancer treated with PD-1/PD-L1 inhibitors between February 2015 and June 2018. HPD was defined as a greater than 50% increase in tumor burden, greater than 2-fold increase in tumor growth rate, or development of extensive (10 or more) new lesions. RESULTS:Patients (n = 102) with renal cell carcinoma (RCC) and patients (n = 101) with urothelial carcinoma (UC) were included. HPD was observed in 13 (6.4%) patients. The median overall survival for patients with progressive disease and HPD was 7.3 months and 3.5 months, respectively. HPD occurred more frequently in patients with UC than in those with RCC (11.9% vs. 0.9%; P = .01). Multivariate analysis showed that UC and creatinine above 1.2 mg/dL were independent predictive factors for HPD. A 30% increase in lymphocyte number following PD-1/PD-L1 inhibitor treatment was a negative predictor of HPD. The incidence of HPD in patients with UC treated with paclitaxel-based chemotherapy was one-third of those treated with PD-1/PD-L1 inhibitors. CONCLUSION:HPD developed predominantly in patients with UC, and the incidence of HPD in patients with RCC was negligible. Treatment with PD-1/PD-L1 inhibitors should be prescribed with caution in patients with UC and creatinine above 1.2 mg/dL.
