Penile Cancer

Taken together, this study demonstrates the prognostic value of the TIME using the three widely available markers CD3, CD8, and PD-L1 in PSCC. Furthermore, it provides additional evidence for a survival benefit of p16INK4A positive cases, compared to p16INK4A negative cases.

A prospective, non-randomized, two-cohort study was designed to evaluate the efficacy of sintilimab combined with chemotherapy in this setting...This preliminary analysis demonstrates that ICI combined with chemotherapy provides durable antitumor activity and a manageable safety profile as neoadjuvant and/or adjuvant therapy for locally advanced PSCC. These results warrant further validation in larger cohorts.

A paclitaxel, ifosfamide, and cisplatin-based regimen achieves response rates around 65%...Compared to standard chemotherapy (e.g. cisplatin, 5-FU, ifosfamide, irinotecan), treatment with romidepsin, quisinostat (HDAC inhibitors (i)), palbociclib (CDK4/6i), or 17-AAG and PU-H71 (HSP90i) reduced cell viability, induced apoptosis, and led to G2 / M cell cycle arrest in most PeCa cells. This research underscores the therapeutic potential of using HDAC, CDK4/6, and HSP90 inhibitors for PeCa management and reveals additional promising targets and biomarkers for future strategies.

Clinically, higher CCL21 expression, elevated CCL21+ CAF signature scores, and stronger CCL21-CCR7 signatures in B cells were associated with favourable outcomes. Together, these data suggest that CCL21+ CAFs or CCL21 are potential prognostic biomarkers for risk stratification and immune microenvironment profiling and highlight the CCL21-CCR7 axis as a candidate pathway for therapeutic modulation of TLS maturity in PSCC.

Extragonadal penile localization of endodermal sinus tumor is rare but has a favorable prognosis when treated with conservative management and chemotherapy. aFP is a useful marker for both diagnosis and follow-up.

In patients with advanced upper urinary tract malignancy who develop penile lesions, secondary involvement should be considered. The absence of regional lymphadenopathy and the disseminated pattern suggest a hematogenous retrograde venous dissemination pathway.

This observation suggests that GPS1 exon 9 sequence is a target of genetic alteration during PSCC pathogenesis. However, the non-recurrent nature of these alterations indicates that they are unlikely to represent oncogenic drivers in this disease.

Early recognition and prompt multidisciplinary intervention remain essential for symptomatic relief and preserving quality of life. Reporting future cases and collaborating with international registries will be necessary to improve understanding of this rare paraneoplastic entity.

Notably, mature TLSs are key for effective anti-tumor immunity, whereas immature TLSs may fail to generate an adequate response. Collectively, these findings highlight TLSs as prognostic biomarkers with prognostic value and therapeutic potential in GU malignancies.
