Case report: Squamous cell carcinoma of the prostate-a clinicopathological and genomic sequencing-based investigation

Pathol Oncol Res. 2023 Nov 28;29:1611343. doi: 10.3389/pore.2023.1611343. eCollection 2023.ABSTRACTSquamous differentiation of prostate cancer, which accounts for less than 1% of all cases, is typically associated with androgen deprivation treatment (ADT) or radiotherapy. This entity is aggressive and exhibits poor prognosis due to limited response to traditional treatment. However, the underlying molecular mechanisms and etiology are not fully understood. Previous findings suggest that squamous cell differentiation may potentially arise from prostate adenocarcinoma (AC), but further validation is required to confirm this hypothesis. This paper presents a case of advanced prostate cancer with a combined histologic pattern, including keratinizing SCC and AC. The study utilized whole-exome sequencing (WES) data to analyze both subtypes and identified a significant overlap in driver gene mutations between them. This suggests that the two components shared a common origin of clones. These findings emphasize the importance of personalized clinical management for prostate SCC, and specific molecular findings can help optimize treatment strategies.PMID:38089646 | PMC:PMC10713708 | DOI:10.3389/pore.2023.1611343
