Abstract
PURPOSE OF REVIEW Testicular cancer is the most common solid malignancy amongst young men, and a large proportion present with stage I disease. The options for management following radical orchiectomy are multifold. We review here approaches to treatment in this setting, providing an update on recent publications. RECENT FINDINGS At Princess Margaret Cancer Centre, we maintain a nonrisk adapted active surveillance approach. With a dedicated surveillance program using low-dose computed tomography imaging, patients are appropriately identified early for treatment on relapse. There are ongoing investigations into minimizing toxicities of treatments for relapse, and in particular, retroperitoneal lymph node dissection (RPLND) presents an attractive alternative. This, though, remains investigational in the setting of seminoma. SUMMARY Testicular cancer is a highly curable malignancy. In stage I disease, an active surveillance approach following radical orchiectomy is preferred, irrespective of risk-profile. This approach serves to limit the toxicity of adjuvant treatment in a significant proportion of patients, while maintaining excellent survival outcomes.

Abstract
Testicular cancer is relatively uncommon and accounts for <1% of all male tumors. However, it is the most common solid tumor in men between the ages of 20 and 34 years, and the global incidence has been steadily rising over the past several decades. Several risk factors for testicular cancer have been identified, including personal or family history of testicular cancer and cryptorchidism. Testicular germ cell tumors (GCTs) comprise 95% of malignant tumors arising in the testes and are categorized into 2 main histologic subtypes: seminoma and nonseminoma. Although nonseminoma is the more clinically aggressive tumor subtype, 5-year survival rates exceed 70% with current treatment options, even in patients with advanced or metastatic disease. Radical inguinal orchiectomy is the primary treatment for most patients with testicular GCTs. Postorchiectomy management is dictated by stage, histology, and risk classification; treatment options for nonseminoma include surveillance, systemic therapy, and nerve-sparing retroperitoneal lymph node dissection. Although rarely occurring, prognosis for patients with brain metastases remains poor, with >50% of patients dying within 1 year of diagnosis. This selection from the NCCN Guidelines for Testicular Cancer focuses on recommendations for the management of adult patients with nonseminomatous GCTs.

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.

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
While about 50% of non- seminomatous germ cell tumors of the testes present as clinical stage I (CSI), further management of these patients continues to be mired in controversy. Active surveillance is a frontline option for low- risk CS I patients and according to some, even the high- risk ones with high embryonal carcinoma (ECA) component and vascular invasion (VI). However, it carries the disadvantage of long- term surveillance, the need for prolonged chemotherapy in case of recurrence and the possibility of secondary malignancies due to radiation exposure from frequent CT scans. One or two cycles of BEP chemotherapy is a popular alternative to active surveillance which carries a very low relapse rate, but valid concerns about overtreatment of a majority of patients, with the attendant chemotherapy- related toxicity exist. Retroperitoneal lymph node dissection has been used as a means of avoiding chemotherapy, especially in high- risk patients, but carries the disadvantage of a high surgical morbidity and complications. As with any major surgical procedure, the best results are dependent on the experience and skill of the individual surgeon.

Abstract
BACKGROUND The outcome of surveillance for Japanese patients with clinical stage I testicular germ cell cancer (GCC) was investigated in the multi-detector computed tomography (MDCT) era. METHODS The medical records of 92 Japanese patients with stage I GCC, who received treatment in our institution between March 1999 and February 2013, were reviewed. As six patients requested and received prophylactic chemotherapy and two patients seriously deviated from surveillance schedule, these patients were excluded from the study. Data from a total 84 patients were analyzed, RESULTS The median follow-up period following diagnosis was 5.1 years (inter-quartile range: IQR, 2.3-7.7 years). Of the 84 patients, eight (9.5 %) had a recurrence of their cancer in this observation period. Regarding histologic subtypes, the recurrence rates were five (9.3 %) of the 54 patients with seminoma and three (10 %) of the 30 patients with nonseminomatous germ cell tumor (NSGCT). All eight patients who experienced a recurrence did so within 2 years; they all underwent induction chemotherapy and remain alive at the time of writing, with no evidence of disease. Among 31 seminoma patients with a tumor more than 4 cm in size and rete testis invasion, cancer recurred in three (9.7 %) during the surveillance period. On the other hand, among the 13 patients with NSGCT and vascular invasion, three (23 %) experienced a recurrence, whereas the figure was zero for the 11 (0 %) patients without vascular invasion. CONCLUSION Fewer than 10 % of Japanese patients with stage I testicular GCC suffered a recurrence in the 5-year observation period of this study. The risk of occult disease, which will result in relapse, might be decreased in the MDCT era. All patients must be fully informed of the anticipated recurrence rate and the potential risks of exposure to chemotherapy agents.

Abstract
For children with stage II testicular malignant germ cell tumors (MGCT), the survival is good with surgery and adjuvant chemotherapy. However, there is limited data on surgical results for cases in which there was no imaging or pathologic evidence of residual tumor, but in which serum tumor markers either increased or failed to normalize after an appropriate period of half-life time post-surgery. To determine the use of chemotherapy for children with stage II germ cell tumors, we analyzed the outcomes (relapse rate and overall survival) of patients who were treated at the Sun Yat-sen University Cancer Center between January 1990 and May 2013. Twenty-four pediatric patients with a median age of 20 months (range, 4 months to 17 years) were enrolled in this study. In 20 cases (83.3%), the tumors had yolk sac histology. For definitive treatment, 21 patients underwent surgery alone, and 3 patients received surgery and adjuvant chemotherapy. No relapse was observed in the 3 patients who received adjuvant chemotherapy, whereas relapse occurred in 16 of the 21 patients (76.2%) treated with surgery alone. There were a total of 2 deaths. Treatment was stopped for 1 patient, who died 3 months later due to the tumor. The other patient achieved complete response after salvage treatment, but developed lung and pelvic metastases 7 months later and died of the tumor after stopping treatment. For children treated with surgery alone and surgery combined with adjuvant chemotherapy, the 3-year event-free survival rates were 23.8% and 100%, respectively (P = 0.042), and the 3-year overall survival rates were 90.5% and 100%, respectively (P = 0.588). These results suggest that adjuvant chemotherapy can help to reduce the recurrence rate and increase the survival rate for patients with stage II germ cell tumors.

Abstract
The management of patients with testicular germ cell tumors (GCT) has evolved significantly over the past 30 years with cure rates approaching nearly 100% for low-stage disease and more than 80% for advanced disease. Controversy surrounds about ideal management of clinical stage I non seminomatous germ cell tumors (CS I NSGCT) of the testis due to multiple treatment options available with more or less equal efficacy. Nerve-sparing retroperitoneal lymph node dissection (RPLND), adjuvant chemotherapy with two cycles of bleomycin, etoposide, and cisplatin , or surveillance have all achieved long-term survival in nearly 100% of patients with clinical stage I NSGCT. Retroperitoneal lymph node dissection is still favoured as the therapy of choice for clinical stage I non-seminomatous germ cell tumors in many centres, but as risk factors for the primary tumor have become better understood, surveillance and risk-adapted therapy, including surveillance for low-risk patients and adjuvant chemotherapy for the high-risk group, is now being considered a therapeutic option. The objective of this study is to review current developments in the management of CS I NSGCT testis with emphasis on risk stratification and treatment recommendations.

Abstract
CONTEXT On behalf of the European Association of Urology (EAU), guidelines for the diagnosis, therapy, and follow-up of testicular cancer were established. OBJECTIVE This article is a short version of the EAU testicular cancer guidelines and summarises the main conclusions from the guidelines on the management of testicular cancer. EVIDENCE ACQUISITION Guidelines were compiled by a multidisciplinary guidelines working group. A systematic review was carried out using Medline and Embase, also taking Cochrane evidence and data from the European Germ Cell Cancer Consensus Group into consideration. A panel of experts weighted the references, and a level of evidence and grade of recommendation were assigned. RESULTS There is a paucity of literature especially regarding longer term follow-up, and results from a number of ongoing trials are awaited. The choice of treatment centre is of the utmost importance, and treatment in reference centres within clinical trials, especially for poor-prognosis nonseminomatous germ cell tumours, provides better outcomes. For patients with clinical stage I seminoma, based on recently published data on long-term toxicity, adjuvant radiotherapy is no longer recommended as first-line adjuvant treatment. The TNM classification 2009 is recommended. CONCLUSIONS These guidelines contain information for the standardised management of patients with testicular cancer based on the latest scientific insights. Cure rates are generally excellent, but because testicular cancer mainly affects men in their third or fourth decade of life, treatment effects on fertility require careful counselling of patients, and treatment must be tailored taking individual circumstances and patient preferences into account. TAKE HOME MESSAGE Although testicular cancer has excellent cure rates, the choice of treatment centre is of the utmost importance. Expert centres achieve better results for both early stage testicular cancer (lower relapse rates) and overall survival (higher stages within clinical trials). For patients with clinical stage I seminoma, adjuvant radiotherapy is no longer recommended as first-line adjuvant treatment.

Abstract
Testicular germ cell tumors represent the most common solid malignancy of young men aged 15-40 years. Histopathologically, testicular germ cell tumors are divided into two major groups: pure seminoma and nonseminoma. The pathogenesis of testicular germ cell tumors remains unknown; however, cryptorchidism is the main risk factor, and molecular studies have shown strong evidence of an association between genetic alterations and testicular germ cell tumors. In cases of suspicion for testicular germ cell tumor, a surgical exploration with orchiectomy is obligatory. After completion of diagnostic procedures, levels of serum tumor markers and the clinical stage based on the International Union Against Cancer tumor-node-metastasis classification should be defined. Patients with early-stage testicular germ cell tumors are treated by individualized risk stratification within a multidisciplinary approach. The individual management (surveillance, chemotherapy or radiotherapy) has to be balanced according to clinical features and the risk of short-term and long-term toxic effects. Treatment for metastatic tumors is based on risk stratification according to International Germ Cell Cancer Collaborative Group classification and is performed with cisplatin-based chemotherapy and residual tumor resection in cases of residual tumor lesion. High-dose chemotherapy represents a curative option for patients with second or subsequent relapses.
