Surveillance versus Adjuvant Treatment with Chemotherapy or Radiotherapy for Stage I Seminoma: A Systematic Review and Meta-Analysis According to EAU COVID-19 Recommendations. MEDICINA (KAUNAS, LITHUANIA) 2022; 58:medicina58111514. [PMID: 36363471 PMCID: PMC9692719 DOI: 10.3390/medicina58111514] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 08/28/2022] [Revised: 10/18/2022] [Accepted: 10/19/2022] [Indexed: 03/10/2023]
Abstract
Background and Objectives: During the coronavirus disease 2019 (COVID-19) outbreak, the European Association of Urology (EAU) Guidelines Office Rapid Reaction Group (GORRG) recommended that patients with clinical stage I (CSI) seminoma be offered active surveillance (AS). This meta-analysis aimed to evaluate the efficacy of AS versus adjuvant treatment with chemotherapy or radiotherapy for improving the overall survival (OS) of CSI seminoma patients. Materials and Methods: A systematic review was performed according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. The PubMed/Medline, EMBASE, and Cochrane Library databases were searched. The primary outcome was 5-year OS, and the secondary outcome was the 5-year relapse-free survival (RFS). The outcomes were analyzed as odds ratios (ORs) and 95% confidence intervals (CIs). Results: A total of 14 studies were included. Overall, the quality scores were relatively high, and little publication bias was noted. In terms of the 5-year OS, 7 studies were analyzed; there was no significant difference between AS and adjuvant treatment (OR, 0.99; 95% CI, 0.41−2.39; p = 0.97). In terms of 5-year RFS, 12 studies were analyzed. Adjuvant treatment reduced the risk of 5-year recurrence by 85% compared with AS (OR, 0.15; 95% CI, 0.08−0.26; p < 0.001). Conclusions: In terms of the OS in CSI seminoma patients, no intergroup difference was noted, so it is reasonable to offer AS, as recommended by the EAU GORRG until the end of the COVID-19 pandemic. However, since there is a large intergroup difference in the recurrence rate, further research on the long-term (>5 years) outcomes is warranted.

Testicular germ cell tumours' clinical stage I: comparison of surveillance with adjuvant treatment strategies regarding recurrence rates and overall survival-a systematic review. World J Urol 2022; 40:2889-2900. [PMID: 36107211 PMCID: PMC9712330 DOI: 10.1007/s00345-022-04145-6] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/11/2021] [Accepted: 07/23/2022] [Indexed: 12/30/2022] Open
Abstract
PURPOSE Testicular germ cell tumours (GCTs) represent the most common malignancy in young adult males with two thirds of all cases presenting with clinical stage I (CSI). Active surveillance is the management modality mostly favoured by current guidelines. This systematic review assesses the treatment results in CSI patients concerning recurrence rate and overall survival in non-seminoma (NS) and pure seminoma (SE) resulting from surveillance in comparison to adjuvant strategies. METHODS/SYSTEMATIC REVIEW We performed a systematic literature review confining the search to most recent studies published 2010-2021 that reported direct comparisons of surveillance to adjuvant management. We searched Medline and the Cochrane Library with additional hand-searching of reference lists to identify relevant studies. Data extraction and quality assessment of included studies were performed with stratification for histology (NS vs. SE) and treatment modalities. The results were tabulated and evaluated with descriptive statistical methods. RESULTS Thirty-four studies met the inclusion criteria. In NS patients relapse rates were 12 to 37%, 0 to 10%, and 0 to 11.8% for surveillance, chemotherapy and for retroperitoneal lymph node dissection (RPLND) while overall survival rates were 90.7-100%, 91.7-100%, and 97-99.1%, respectively. In SE CSI, relapse rates were 0-22.3%, 0-5%, and 0-12.5% for surveillance, radiotherapy, chemotherapy, while overall survival rates were 84.1-98.7%, 83.5-100%, and 92.3-100%, respectively. CONCLUSION In both histologic subgroups, active surveillance offers almost identical overall survival as adjuvant management strategies, however, at the expense of higher relapse rates. Each of the management strategies in CSI GCT patients have specific merits and shared-decision-making is advised to tailor treatment.

Abstract
PURPOSE OF REVIEW Germ cell testicular tumors (GCTTs) are the most common malignancy in young men, and the incidence is increasing worldwide. Most patients present with clinical stage I (CS1) disease, and active surveillance is being increasingly adopted as the preferred initial treatment modality. In this review, we describe the concept of conditional risk of relapse (CRR), an evolving risk estimate for CS1 GCTT patients on active surveillance who have not relapsed. RECENT FINDINGS At diagnosis, patients are often counseled about their initial risk of relapse based on known risk factors present at diagnosis. However, the risk estimate becomes less informative in patients who have survived a period of time without experiencing relapse. CRR, on the other contrary, provides specific information on a patient's evolving risk of relapse over time. This dynamic estimate can be used to tailor surveillance protocols based on future risk of relapse within risk subgroups. SUMMARY Implementation of CRR in patients on active surveillance can reduce the burden of follow-up, the number of physician visits and tests, and lower costs for the healthcare system. Finally, CRR estimates provide patients with a meaningful, evolving risk estimate, and may help reassure patients and reduce potential anxiety while continuing active surveillance.

Recommendations for surveillance and follow-up of men with testicular germ cell tumors: a multidisciplinary consensus conference by the Italian Germ cell cancer Group and the Associazione Italiana di Oncologia Medica. Crit Rev Oncol Hematol 2019; 137:154-164. [PMID: 31014511 DOI: 10.1016/j.critrevonc.2019.03.006] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/09/2019] [Revised: 03/09/2019] [Accepted: 03/12/2019] [Indexed: 11/23/2022] Open
Abstract
BACKGROUND No compelling evidence is available about surveillance and follow-up of patients with testicular germ cell tumour (TGCT). METHODS In the light of the best clinical evidence, the Italian Germ cell cancer Group (IGG) and the Associazione Italiana di Oncologia Medica (AIOM) set up a multidisciplinary national consensus conference, involving 42 leading experts and 3 TGCT survivors. A minimum of 50% of votes was required in order to achieve a consensus recommendation on 29 questions. RESULTS Recommendations have been summarized in three tables, divided by stage I seminoma, stage I nonseminoma and the advanced disease, which may be useful for clinicians to appropriately choose the clinical investigation and its timing during the surveillance and follow-up of TGCT patients based on an accurate estimation of their risk of disease relapse. CONCLUSIONS The IGG-AIOM consensus recommendations may help clinicians to choose appropriate clinical investigations for the surveillance and follow-up of TGCT patients.

Abstract
Germ cell testicular tumors are the most commonly diagnosed cancer in young men, with cure rates exceeding 95%. Clinical stage 1 disease is the most common manifestation, with radical orchiectomy curing the majority of Clinical stage 1 patients, making active surveillance the treatment of choice, with a cancer specific survival nearing 100% and low relapse rates. However, in metastatic disease, chemotherapy, radiotherapy, and surgery are curative options. Chemotherapy remains the mainstay of therapy for advanced disease with surgical management of residual disease. Patients with advanced disease should be treated in high volume experienced academic centers with multidisciplinary teams. Research exploring refinement of diagnosis and treatment, and lowering treatment burden is underway.

Abstract
Clinical stage I testicular germ cell tumours (TGCT) are highly curable neoplasms. The treatment of stage I testicular cancer is complex and requires a multidisciplinary approach. Standard options after radical orchiectomy for seminoma include active surveillance, radiation therapy or 1-2 cycles of carboplatin, and options for nonseminoma include active surveillance, retroperitoneal lymph node dissection (RPLND) or 1-2 cycles of bleomycin plus etoposide plus cisplatin (BEP). All the options should be discussed with each patient and treatment choices should be made by shared decision making as virtually all patients with clinical stage I TGCT can be cured of their disease. Long-term survival of men with stage I disease is ∼99% and care must be taken to limit the long-term risks of treatment. Orchiectomy is curative in the majority of patients. The management of clinical stage I TGCT remains controversial among experts at high-volume centres throughout the world. The main controversy is whether to overtreat a substantial number of patients with stage I disease to prevent relapse, or to observe and treat only patients who experience disease relapse as adjuvant treatment and surveillance strategy both bring curative outcome. Thus, a summary of the available evidence in stage I disease and recommendations for disease management from a high-volume centre such as Indiana University might be of interest to treating clinicians.

Abstract
The BRCA1-associated protein-1 (BAP1) tumor predisposition syndrome (BAP1-TPDS) is a recently identified hereditary cancer syndrome. Germline mutations in this tumor suppressor gene predispose families to the development of various malignancies. The molecular functions of the gene as well as the clinical phenotype of the syndrome are still being clarified. We sought to conduct a comprehensive review of published research into BAP1-TPDS to more thoroughly delineate the clinical implications of germline BAP1 mutations. We also report two additional families with germline BAP1 mutations. Current evidence demonstrates that germline BAP1 mutations predispose families to uveal melanoma, renal cell carcinoma, malignant mesothelioma, cutaneous melanoma, and possibly to a range of other cancers as well. Some of these cancers tend to be more aggressive, have a propensity to metastasize, and onset earlier in life in patients with BAP1 mutations as compared to non-predisposed patients with equivalent cancers. Although further research is necessary, this information can aid in the management, diagnosis, and therapy of these patients and their families, and highlights the importance of genetic counseling.

Abstract
Management of testicular seminoma has benefited from numerous advances in imaging, radiotherapy, and chemotherapy over the last 50 years leading to nearly 100% disease-specific survival for low-stage seminoma. This article examines the evaluation and management of low-stage testicular seminoma, which includes clinical stage I and IIA disease. Excellent outcomes for stage I seminoma are achieved with active surveillance, adjuvant radiotherapy, and adjuvant single-agent carboplatin. Current areas of research focus on optimizing surveillance regimens and minimizing the morbidity and long-term complications of adjuvant treatment. Radiotherapy continues to be the primary treatment option for patients with clinical stage IIa disease.
