Abstract
Patients with marker-negative clinical stage IIA/B seminoma or nonseminoma represent a therapeutic challenge, as 20-30% might harbor nonmalignant histologies. MicroRNA 371a-3p (miR371) may represent a biomarker with diagnostic and predictive properties in testicular germ cell tumors (TGCTs). We evaluated the predictive accuracy of this biomarker in identifying the presence or absence of lymph node metastases (LNMs) in clinical stage IIA/B TGCT. In a cohort of 24 consecutive patients with marker-negative clinical stage IIA/B TGCT (n = 15 seminoma, n = 9 nonseminoma) serum miR371 was assessed 1 d before nerve-sparing retroperitoneal lymphadenectomy. Histology revealed metastatic TGCT in 22/24 patients (91.7%), with positive miR371a findings for 20 of these 22 patients with metastases (90.9%). Histology revealed no malignancy in one patient and lymphoma in another, both of whom had negative miR371a findings. One additional patient with pure teratoma and one with a microscopic seminomatous LNM had false-negative miR371a findings. The miR371 assay had sensitivity of 90.9% and specificity of 50%. The positive predictive value was 100.0% and the negative predictive value was 75.0%. According to the data available, miR371a represents a highly reliable, personalized tumor marker for predicting the presence of low-volume retroperitoneal LNMs in marker-negative TGCT. miR371 has potential for inclusion in the diagnostic armamentarium for men with equivocal lymph nodes to facilitate avoidance of unnecessary treatment and the associated toxicity. PATIENT SUMMARY: Our study demonstrates that blood tests for the biomarker miR371 are highly reliable in predicting the presence of lymph node metastases in patients with stage IIA/B testicular cancer. For patients with equivocal findings, use of this test may help in avoiding unnecessary treatment.

Initial surveillance in men with marker negative clinical stage IIA non-seminomatous germ cell tumours. BJU Int 2024; 133:717-724.

Abstract
OBJECTIVES To assess whether extended surveillance with repeated computed tomography (CT) scans for patients with clinical stage IIA (CS IIA; <2 cm abdominal node involvement) and negative markers (Mk-) non-seminomatous germ cell tumours (NSGCTs) can identify those with true CS I. To assess the rate of benign lymph nodes, teratoma, and viable cancer in retroperitoneal lymph node dissection (RPLND) histopathology for patients with CS IIA Mk- NSGCT. PATIENTS AND METHODS Observational prospective population-based study of patients diagnosed 2008-2019 with CS IIA Mk- NSGCT in the Swedish and Norwegian Testicular Cancer Group (SWENOTECA) registry. Patients were managed with surveillance, with CT scans, and tumour markers every sixth week for a maximum of 18 weeks. Patients with radiological regression were treated as CS I, if progression with chemotherapy, and remaining CS IIA Mk- disease with RPLND. The end-point was the number and percentage of patients down-staged to CS I on surveillance and rate of RPLND histopathology presented as benign, teratoma, or viable cancer. RESULTS Overall, 126 patients with CS IIA Mk- NSGCT were included but 41 received therapy upfront. After surveillance for a median (range) of 6 (6-18) weeks, 23/85 (27%) patients were in true CS I and four (5%) progressed. Of the remaining 58 patients with lasting CS IIA Mk- NSGCT, 16 received chemotherapy and 42 underwent RPLND. The RPLND histopathology revealed benign lymph nodes in 11 (26%), teratoma in two (6%), and viable cancer in 29 (70%) patients. CONCLUSIONS Surveillance with repeated CT scans can identify patients in true CS I, thus avoiding overtreatment. The RPLND histopathology in patients with CS IIA Mk- NSGCT had a high rate of cancer and a low rate of teratoma.

Treatment Outcomes for Men with Clinical Stage II Nonseminomatous Germ Cell Tumours Treated with Primary Retroperitoneal Lymph Node Dissection: A Systematic Review. Eur Urol Focus 2023; 9:541-546. [PMID: 36379869 DOI: 10.1016/j.euf.2022.11.003] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/16/2022] [Revised: 10/19/2022] [Accepted: 11/02/2022] [Indexed: 11/13/2022]
Abstract
CONTEXT Guidelines recommend primary retroperitoneal lymph node dissection (RPLND) as a treatment option for tumour marker-negative stage II nonseminomatous germ cell tumour (NSGCT). OBJECTIVE To review the literature on oncological outcomes for men with stage II NSGCT treated with RPLND. EVIDENCE ACQUISITION A systematic review of studies describing clinicopathological outcomes following primary RPLND in stage II NSGCT was conducted in the MEDLINE, EMBASE, and Cochrane Database of Systematic Reviews databases according to the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols (PRISMA-P) statement. Baseline data, perioperative and postoperative parameters, and oncological outcomes were collected. EVIDENCE SYNTHESIS In total, 12 of 4387 studies were included, from which we collected data for 835 men. Among men with clinical stage II NSGCT, pathological stage II was confirmed in 615 of 790 patients (78%). Most studies administered adjuvant chemotherapy in cases with large lymph nodes, multiple affected lymph nodes, or persistently elevated tumour markers. Recurrence was observed in 12-40% of patients without adjuvant chemotherapy and 0-4% of patients who received adjuvant chemotherapy. CONCLUSIONS The literature describing RPLND in clinical stage II NSGCT is heterogeneous and no meta-analysis was possible, but RPLND can provide accurate staging and may be curative in selected patients. PATIENT SUMMARY We reviewed the literature to summarise results after surgical removal of enlarged lymph nodes in the back of the abdomen in men with testis cancer. This procedure provides accurate information on how far the cancer has spread and may provide a cure in selected patients.
