Abstract
Testicular cancer is the most prevalent tumor among males aged 15 to 35, resulting in a significant number of newly diagnosed cases and fatalities annually. Non-coding RNAs (ncRNAs) have emerged as key regulators in various cellular processes and pathologies, including testicular cancer. Their involvement in gene regulation, coding, decoding, and overall gene expression control suggests their potential as targets for alternative treatment approaches for this type of cancer. Furthermore, epigenetic modifications, such as histone modifications, DNA methylation, and the regulation by microRNA (miRNA), have been implicated in testicular tumor progression and treatment response. Epigenetics may also offer critical insights for prognostic evaluation and targeted therapies in patients with testicular germ cell tumors (TGCT). This comprehensive review aims to present the latest discoveries regarding the involvement of some proteins and ncRNAs, mainly miRNAs and lncRNA, in the epigenetic aspect of testicular cancer, emphasizing their relevance in pathogenesis and their potential, given the fact that their specific expression holds promise for prognostic evaluation and targeted therapies.

Abstract
The definitive cure rate for clinical stage I testicular seminoma is very close to 100%, and prophylactic irradiation of the regional lymph nodes is associated with a low morbidity. Nevertheless, in recent years a “wait-and-see” policy has been proposed by some researchers. We analysed the cost/benefit ratio of radiotherapy (RT) by review of the case histories of 299 patients treated at the Department of Radiotherapy of the Istituto Nazionale per lo Studio e la Cura dei Tumori in Milan from January 1968 to December 1989. The 5-year overall survival was 99% (97.5% at 10 years), while the 10-year disease-free survival was 96%. The recurrence rate was 2.3%, but no patient relapsed in the irradiated areas. Acute toxicity was very moderate with only 4 (1.3%) serious radiation sequelae occurring 6 to 27 years after treatment. However, 9 second malignancies (3%) were observed. Lastly, we have calculated the costs for our National Health Service comparing surveillance policy and prophylactic irradiation.

Abstract
Aims and background Pure testicular seminoma has historically been treated with post-orchidectomy radiation therapy with excellent results. Recently, several aspects of the treatment of stage I seminoma have been questioned. We assessed long-term results and toxicity of patients with pure testicular seminoma treated at the Department of Radiation Oncology of S. Chiara Hospital, Trento. Methods From 1953 to 1987, 102 patients with stage I pure testicular seminoma were given megavoltage irradiation with curative intent. All patients had a minimum follow-up of 3 years (maximum 37 years, median 13 years). They received a mean para-aortic/pelvic dose of 33.07 Gy (range 23.70-45.20 Gy) with different doses and fields reflecting the change in techniques over a long period of time. Results The cause-specific actuarial survival at 30 years was 99% and crude survival 67%. One patient had an out-field relapse (inguinal) after a few months and was cured with radiotherapy and chemotherapy. Another patient relapsed with widespared metastases and died after 1 year of progressive disease. Early toxycity was mild and the treatment was well tolerated. Late side effects were reported in 8/102 patients. Conclusion In our series adjuvant radiation therapy resulted in cure rates corresponding to those reported in the literature. The 30-year actuarial survival of 99% was extremely good and the toxicity of the treatment was mild. Post-orchidectomy radiation to the para-aortic and ipsilateral pelvic nodes is a safe and effective method of preventing recurrences and is currently to be considered the treatment of choice in stage I testicular seminoma.

Posttreatment surveillance after paraaortic radiotherapy for stage I seminoma: a systematic analysis. J Cancer Res Clin Oncol 2009; 136:227-32. [PMID: 19680688 DOI: 10.1007/s00432-009-0653-x] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/27/2009] [Accepted: 07/21/2009] [Indexed: 10/20/2022]
Abstract
CONTEXT The extent and duration of routine follow-up after paraaortic (PA) radiotherapy for stage I seminoma remain controversial in terms of efficacy, costs of technical investigations and long-term morbidity. OBJECTIVE To analyze the current literature assessing routine follow-up after PA radiotherapy for stage I seminoma. EVIDENCE ACQUISITION We identified all published reports on PA radiotherapy for stage I seminoma (1986-2005). We analyzed time patterns of recurrence, sites and methods of detection of relapse, and follow-up programs used. EVIDENCE SYNTHESIS We identified 11 publications reporting outcome in 2,280 patients. Median time to recurrence in 80 relapsing patients was 15.5 months. Less than 10% of recurrences were diagnosed beyond the third year of follow-up. Isolated locoregional or distant recurrence was observed in 52 and 20 patients, respectively, without significant difference in median time to relapse. 19 out of 43 recurrences with reported method of detection of relapse were diagnosed by routine technical investigations. There was no significant difference in time to relapse between those patients followed with low volume as compared to high-volume imaging protocols. CONCLUSIONS Our data suggest that technical investigations in posttreatment surveillance should be restricted to the first 3 years of follow-up. Furthermore, surveillance programs with a high volume of imaging apparently do not lead to earlier detection or less advanced stage at the time of relapse as compared to protocols with low volume imaging.

Abstract
Ninety-four patients with Stage I seminoma of the testis, treated between November 1989 and December 1991, received short duration radiotherapy (2000 cGy in 8 fractions) to the para-aortic area only. The treatment was well tolerated and, after a median follow-up time of 34 months (minimum 15 months), no patient has relapsed in the abdomen. One patient developed an apparently solitary distant metastasis from a latent teratoma and is disease free after chemotherapy. This form of radiotherapy would appear to be well-tolerated with a low relapse rate. It offers the advantage of a simpler and shorter technique compared with conventional therapy and avoids the necessity of intensive surveillance to detect relapse.
