Abstract
The contemporary paradigm of testicular cancer management is achieving high and durable cure rates while minimizing the burden of treatment given the potential long-term toxicities associated with radiation therapy and systemic therapies. The management of low-stage seminoma has seen significant changes in recent years. Nuances of surveillance strategies for stage I seminoma exist and continue to evolve. Emerging data show retroperitoneal lymph node dissection is a viable treatment option for selected patients with clinical stage IIA and IIB seminoma.

Primary retroperitoneal lymph node dissection for clinical stage II seminoma: A systematic review and meta-analysis of safety and oncological effectiveness. Urol Oncol 2024; 42:102-109. [PMID: 38360519 DOI: 10.1016/j.urolonc.2024.01.014] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/31/2023] [Revised: 11/21/2023] [Accepted: 01/08/2024] [Indexed: 02/17/2024]
Abstract
To evaluate the oncological outcomes and safety of primary retroperitoneal lymph node dissection (RPLND) in patients with clinical stage (CS) II seminomatous testicular germ cell tumor (TGCT). A literature search using PubMed, Scopus, and Cochrane Library was conducted on July 2023 to identify relevant studies according to the Preferred Reporting Items for Systematic Review and Meta Analysis (PRISMA) guidelines. The pooled recurrence rate and treatment-related complications were calculated using a random effects model. Overall 8 studies published between 1997 and 2023 including a total of 355 patients were selected for systematic review and meta-analysis with the overall median follow-up of 38 months. The overall and infield recurrence rate were 0.14 (95% CI: 0.08-0.22) and 0.04 (95% CI: 0.00-0.11), respectively. The overall pooled rate of ≥ Clavien Dindo grade III complications was 0.04 (95% CI: 0.01-0.10); there was no significant heterogeneity (I^2 = 35.10%, P = 0.19). Antegrade ejaculation was preserved with the overall pooled rate of 0.98 (95% CI: 0.95-1.00); there was no significant heterogeneity on Chi-square and I2 tests (I^2 = 0.00%, P = 0.58). Primary RPLND is a safe and effective treatment option for patients with CS II seminomatous TGCT resulting highly promising cure rates combined with low treatment-associated adverse events, at medium-term follow-up. However, owing to the lack of comparative studies to the current standard of care and the limited follow-up, individual decision must be made with the informed patient in a shared decision process together with a multidisciplinary team.

The prognostic impact of treatment centralization in patients with testicular germ cell tumors: analysis of hospital-based cancer registry data in Japan. Int J Clin Oncol 2024; 29:318-324. [PMID: 38265529 DOI: 10.1007/s10147-023-02457-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/23/2023] [Accepted: 12/11/2023] [Indexed: 01/25/2024]
Abstract
BACKGROUND To identify the prognostic impact of treatment centralization in patients with testicular germ cell tumors (TGCT). METHODS We used a hospital-based cancer registry data in Japan to extract seminoma and non-seminoma cases that were diagnosed in 2013, histologically confirmed, and received the first course of treatment. To compare the 5-years overall survival (OS) rates of patients stratified by institutional care volume, we performed a Cox proportional hazards regression analysis using inverse probability of treatment weighting (IPTW) method to adjust patient backgrounds. RESULTS A total of 1767 TGCT patients were identified. The 5-years OS rates for stage II and III TGCT patients treated at low-volume institutions (< 7 cases) were significantly worse than high-volume institutions (≥ 7 cases) (91.2% vs. 83.4%, p = 0.012). Histological stratification revealed that 5-year OS rates for stage II and III seminoma patients in the low-volume group were significantly worse than the high-volume group (93.5% vs. 84.5%, p = 0.041). Multivariate OS analysis using an IPTW-matched cohort showed that institutional care volume was an independent prognostic factor (hazard ratio 2.13 [95% confidence interval: 1.23-3.71], p = 0.0072). CONCLUSION Our results indicate that stage II and III TGCT patients experience lower survival rates at low-volume institutions and would benefit from treatment centralization.

Retroperitoneal Lymph Node Dissection in Clinical Stage IIA/B Metastatic Seminoma: Results of the COlogne Trial of Retroperitoneal Lymphadenectomy In Metastatic Seminoma (COTRIMS). Eur Urol Oncol 2024; 7:122-127. [PMID: 37438222 DOI: 10.1016/j.euo.2023.06.004] [Citation(s) in RCA: 8] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/17/2023] [Revised: 05/06/2023] [Accepted: 06/23/2023] [Indexed: 07/14/2023]
Abstract
BACKGROUND Radiation therapy and systemic chemotherapy are recommended treatment options in marker-negative clinical stage (CS) IIA/B seminoma. Despite high cure rates of 82-94%, both therapeutic options are associated with significant long-term toxicities. OBJECTIVE To evaluate the feasibility, oncological efficacy, and treatment-associated morbidity of primary nerve-sparing retroperitoneal lymph node dissection (nsRPLND) in CS IIA/B seminoma. DESIGN, SETTING, AND PARTICIPANTS A prospective, single-arm, clinical phase 2 trial including CS IIA/B seminoma patients was conducted. INTERVENTION Primary nerve-sparing retroperitoneal lymphadenectomy. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS Relapse-free and overall survival, surgery-associated complications according to the Clavien-Dindo classification, and Kaplan-Meier methods for survival calculation were assessed. RESULTS AND LIMITATIONS Thirty patients at a mean age of 39.1 (34-52) yr with marker-negative CS IIA and IIB seminomas were recruited. The median follow-up was 22 (8-30) mo. Nineteen (63%) and 11 (36%) patients were diagnosed with stages IIA and B, respectively, at the time of primary diagnosis. Fourteen (47%) and 16 (53%) patients were diagnosed with CS IIA and IIB, respectively, at the time of nsRPLND. Twenty-seven and three patients underwent open and robot-assisted nsRPLND, respectively. The median operating room time was 125 (115-145) min, median blood loss was <150 ml, and median time of hospitalization was 4.5 (3-9) d. Four (13%) patients experienced Clavien-Dindo grade 3a complications. Lymph node histology revealed seminoma in 25 (80%) patients; two and three patients demonstrated embryonal carcinoma and benign disease, respectively. Sixteen patients underwent a serum analysis of miR371 preoperatively, which predicted metastatic disease in 12/13 and benign histology in 3/3 patients. Three of 30 (10%) patients developed an outfield relapse 4, 6, and 9 mo postoperatively and were salvaged by systemic chemotherapy. Limitations are the low patient number and length of follow-up. CONCLUSIONS The nsRPLND approach results in a high cure rate at midterm follow-up and is associated with a low frequency of treatment-associated morbidities, making this approach a feasible alternative to radiation therapy or systemic chemotherapy. PATIENT SUMMARY The standard treatment of clinical stage IIA/B seminomas is radiation therapy or chemotherapy, which results in a significantly increased frequency of long-term toxicity and secondary neoplasms. In this trial, we demonstrate that nerve-sparing retroperitoneal lymph node dissection is a feasible therapeutic approach with low morbidity and high oncological efficacy.

Serum Levels of MicroRNA-371a-3p (M371) Can Predict Absence or Presence of Vital Disease in Residual Masses After Chemotherapy of Metastatic Seminoma. Front Oncol 2022; 12:889624. [PMID: 35600346 PMCID: PMC9121896 DOI: 10.3389/fonc.2022.889624] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/04/2022] [Accepted: 04/11/2022] [Indexed: 11/13/2022] Open
Abstract
BackgroundRadiological evaluation of postchemotherapy residual masses of metastatic seminoma is characterized by poor diagnostic accuracy. Serum levels of microRNA-371a-3p (M371) involve high specificity and sensitivity for the primary diagnosis of seminoma. We evaluated if M371 levels can indicate the presence of vital disease in postchemotherapy residual masses in patients with metastatic seminoma.MethodsTwenty-three seminoma patients (median age 52 years) with residual masses had posttreatment measurements of serum M371 levels (group A), fourteen of whom had measurements also beforehand. The posttreatment results were compared with the clinical outcome during follow-up. Eleven patients with complete remission after treatment of metastatic seminoma (group B) and 33 men with non-malignant testicular diseases (group C) served as controls. M371 serum levels were measured by quantitative real-time PCR using miR-30b-5p as endogenous control. An evaluation was performed with descriptive statistical methods.ResultsTwenty-two patients of Group A had uneventful follow-up so far, twenty-one of whom had M371 level <5, and one other had a mildly elevated level below relative quantity (RQ) = 10. One patient with a level of RQ = 26.2 rapidly progressed. The median posttreatment M371 level of the non-progressing patients of group A is not significantly different from the median level of the control group with complete remission (B). Before treatment, the median M371 levels in groups A and B were 507.6 and 143.9, respectively. In both groups, significant drops in M371 levels resulted from treatment.ConclusionNormal M371 serum levels at the time of completion of treatment of metastatic seminoma indicate the absence of vital seminoma in residual masses, while elevated levels >RQ = 10 predict the presence of disease. The optimal timing of M371 measurement after chemotherapy and the appropriate cutoff level still need to be determined. Based on the present results, measuring serum M371 levels involves the potential of a novel tool for assessing postchemotherapy residual masses of metastatic seminoma.
