Abstract
Penile squamous cell carcinoma (PSCC) is a rare malignancy, and first-line therapy typically involves cisplatin-based chemotherapy. However, these regimens are often unsuitable for patients with poor performance status or advanced age due to their toxicity. This retrospective, multicenter study evaluated patients with metastatic PSCC who received immune checkpoint inhibitor (ICI) therapy between 2017 and 2024. A total of 10 patients met the inclusion criteria. The median age was 75 years, and 50% had an ECOG performance status of 2 or higher. The objective response rate (ORR) was 30%, and the disease control rate (DCR) was 40%. The duration of response and disease control was over 12 months and 8 months respectively in all patients with response or disease control. The median progression-free survival (PFS) was 2.82 months, and the median overall survival (OS) was 4.32 months. PD-L1 and HPV-positive patients had a 67% response rate (n = 2/3). No patients experienced severe immune-related adverse events (irAEs). This multicenter retrospective analysis suggests that ICI monotherapy may be a promising treatment option for patients with advanced PSCC who are either ineligible for first-line platinum-based chemotherapy or who have progressed after platinum-based chemotherapy, including those with poor performance status. Further studies are needed to confirm these findings and identify baseline patient characteristics that may optimize selection criteria.
期刊介绍:
Experimental Hematology & Oncology is an open access journal that encompasses all aspects of hematology and oncology with an emphasis on preclinical, basic, patient-oriented and translational research. The journal acts as an international platform for sharing laboratory findings in these areas and makes a deliberate effort to publish clinical trials with 'negative' results and basic science studies with provocative findings.
Experimental Hematology & Oncology publishes original work, hypothesis, commentaries and timely reviews. With open access and rapid turnaround time from submission to publication, the journal strives to be a hub for disseminating new knowledge and discussing controversial topics for both basic scientists and busy clinicians in the closely related fields of hematology and oncology.
