(UroToday.com) The 2025 GU ASCO annual meeting featured a session on emerging trends in germ cell tumors and a presentation by Dr. Axel Heidenreich discussing primary retroperitoneal lymph node dissection (RPLND) in stage II seminoma. The clinical presentation of seminomas is such that <10% of patients present in de novo clinical stage IIA/B. Importantly, 15% of stage I seminoma patients relapse with 90-95% of relapses located in the retroperitoneum. Relapse free survival rates vary between 82-94% and 5-year overall survival is ~95%. Standard treatment for seminoma is (i) 3 cycles of BEP chemotherapy or 4 cycles of EP chemotherapy, (ii) radiation therapy with 30 Gy in CS IIA seminoma and 36 Gy in CS IIB seminoma, (iii) an optional treatment option is radiation therapy + 1 cycle AUC 7. With all of these treatment options, the 5-year overall survival is 95%. The problem with all of these treatments is long-term toxicity, which includes additional solid cancers, leukemia, cardiovascular, and diabetes mellitus:

(UroToday.com) The 2025 GU ASCO annual meeting featured a session on emerging trends in germ cell tumors and a presentation by Dr. Nabil Adra discussing the current evidence and indications for high-dose chemotherapy in testicular cancer. Dr. Adra highlighted that 20% of patients with metastatic germ cell tumor will progress after first line therapy: 11% for good risk disease, 25% for intermediate risk disease, and 46% for poor risk disease. Progression is defined by serology and radiography, and we should use caution with initiating salvage therapy with borderline AFP and hCG. Options to treat relapsed germ cell tumors include salvage surgery, standard-dose chemotherapy, and high-dose chemotherapy. The International Prognostic Factors Study Group previously established prognostic variables as:

Dr. Meric-Bernstam started her presentation by highlighting that bladder cancer has a HER2 alteration incidence of 12.4%. Across all cancers, 2.7% are HER2 IHC 3+:

(UroToday.com) The 2025 GU ASCO annual meeting featured a session on the ABCs of antibody drug conjugates and a presentation by Dr. Terence Friedlander discussing novel drug combinations with antibody drug conjugates. One of the main reasons why we should pursue combination therapy in metastatic urothelial carcinoma is that there is attrition of patients across lines of therapy:

(UroToday.com) The 2025 GU ASCO annual meeting featured a prostate cancer session and a presentation by Dr. Jesus Casillas discussing a pooled analysis of SOLAR and SATURN clinical trials comparing progression following systemic and tumor-directed therapy for de novo versus recurrent PSMA PET–defined oligo-M1 prostate cancer. Oligometastatic castration sensitive prostate cancer (CSPC) presents a unique opportunity for curative or long term disease control through targeted and systemic therapies. Emerging studies favor a multimodal approach, combining treatment of the primary and metastases with short term intensified systemic therapy, aiming to improve survival and local control while minimizing toxicity from indefinite systemic therapy. This post-hoc analysis of the SOLAR (NCT03298087) and SATURN (NCT03902951) trials, which evaluated systemic and tumor-directed therapy in PSMA-PET defined oligo-M1 (≤5 metastases) de novo and recurrent oligometastatic CSPC, respectively, aims to draw inferences on biology and oncologic outcome.

(UroToday.com) The 2025 GU ASCO annual meeting featured a prostate cancer session and a presentation by Dr. Glenn Bauman discussing a prospective provincial registry of PSMA PET/CT for recurrent prostate cancer. While most prostate cancer is initially localized, about 25% of patients treated with surgery or radiation experience biochemical failure, and traditional imaging struggles to detect sites of these recurrences early. PSMA PET/CT scanning has emerged as a more effective tool for detecting recurring prostate cancer, potentially enabling earlier treatment interventions. PREP was initiated in Ontario to provide access and characterize the performance of PSMA PET CT (18F-DCFPyL PSMA PET-CT) among men with recurrent prostate cancer after primary definitive treatment (radical prostatectomy or radiation therapy).

(UroToday.com) The 2025 GU ASCO annual meeting featured a prostate cancer session and a presentation by Dr. Benjamin Maughan discussing a prospective trial of a structured exercise program to lessen fatigue in patients with advanced prostate cancer undergoing androgen deprivation therapy (ADT). Cancer-related fatigue, one of the most significant issues affecting quality of life, is reported by up to 75% of men with advanced prostate cancer on ADT. Importantly, exercise may serve as a tool to improve fatigue in cancer patients. As such, Dr. Maughan and colleagues examined the effect of a structured exercise program on fatigue in men with advanced prostate cancer.

(UroToday.com) The 2025 GU ASCO annual meeting featured a prostate cancer session and a presentation by Dr. Melissa Abel discussing radium-223 without androgen deprivation therapy (ADT) in patients with biochemically recurrent prostate cancer and PET findings in the bones. Biochemically recurrent prostate cancer patients have a rising PSA after definitive surgery or radiation, but negative CT/99Tc scans. While ADT-based strategies are commonly used, they can be associated with life-altering toxicities and have not been shown to improve survival.

(UroToday.com) The 2025 GU ASCO annual meeting featured a prostate cancer session and a presentation by Dr. Ivan de Kouchkovsky discussing the impact of baseline PSMA PET in patients with metastatic castration-resistant prostate cancer (mCRPC) starting first-line androgen receptor signaling inhibitor therapy.
