1. Access to care, epidemiological variation and cost-effectiveness in the treatment of testis cancer.Because testis cancer is a rare disease, understanding of early symptoms, screening and access to health care can have huge implications regarding the treatment and eventual outcomes of disease. The following presentations addressed some of these issues.
In a study of nearly 6,000 men in the SEER (Surveillance, Epidemiology, End Results) database, uninsured men were more likely to present with advanced or metastatic disease, get radiation therapy if they had Seminoma (indicating advanced disease) and die of testis cancer.

In another study involving the National Cancer Database Registry, investigators from Vanderbilt University looked at compliance rates with the National Comprehensive Cancer Network (NCCN) Guidelines - which recommend serum tumor markers be drawn prior orchiectomy. The authors found that young patients, low income patients, those treated at an academic center outside of the South or Midwest were more likely to be treated in compliance with the NCCN Guidelines.

In a second study using the National Cancer Database Registry, researchers looked at over 75k men with testis cancer and found that non-Caucasian men had higher rates of advanced (Stage III) disease and worse overall survival. African-American men had the highest rates of testis cancer-specific death.
In a cost-effectiveness analysis, researchers from Kansas City, Kansas examined the role of testicular self-examination in asymptomatic men. Using Medicare reimbursements to estimate costs, they calculated that the cost of treating an advanced stage testis cancer was roughly $50k, while the costs of office evaluation ranged from $150-600, and the cost of an orchiectomy for early-stage disease is approximately $20k. Therefore, they concluded - contrary to the recommendation of the US Preventative Services Task Forces (USPSTF) - that testicular self-examination is cost-effective and should not be discouraged.

2. Treatment of early stage disease.The treatment of Clinical Stage 1 testis cancer is evolving (click here to see our blog on the treatment of clinical stage 1 NSGCT). Most patients are cured with orchiectomy alone, and the remainder can be salvaged with chemotherapy and/or surgery. Therefore active surveillance is emerging as the most common management strategy for these patients with primary retroperitoneal lymph node dissection (RPLND) and chemotherapy as second options. However, given the young age and relatively good health of men with testis cancer, the long-term implications of each management strategy are not fully realized. These presentations address this topic.
To investigate the use of active surveillance for Stage 1 testis cancer, researchers in this study used data from the 75k men in the National Cancer Database Registry with testicular cancer. For Clinical Stage 1 Seminoma, they found the rates of active surveillance increased from 25% to 55% over the time period from 1998-2011 with a concomitant decrease in radiation from 72% to 28%. Interestingly, for non-seminomatous germ cell tumors the rates of active surveillance remained stable (58-66%) while rates of primary chemotherapy increased (28%) and retroperitoneal lymph node dissection (RPLND) decreased (12.9%) in 2011. However, in 2011, 50% of patients with cT1a disease received chemotherapy and not active surveillance.

In a retrospective study of 48 men with clinical stage 1 seminoma on active surveillance, only 2 patients recurred giving a 95% recurrence free survival at 3 years.

In an update of prospective, single arm, phase II clinical trial, 40 patients with high-risk clinical stage 1 non-seminomatous germ cell tumors received one cycle of BEP (Bleomycin, Etoposide and Cisplatinum chemotherapy). With 15-years of follow-up, one patient recurred and died of metastases, three developed a contralateral testis tumor and three developed a secondary malignancy.

3. Retroperitoneal lymph node dissection (RPLND) for advanced (retrocrural) diseaseWhile the overall survival rate for patients with testis cancer is excellent, after chemotherapy, some patients will develop chemotherapy-resistant teratoma that must be resected surgically. One of the more challenging locations for a teratoma is behind the diaphragm in the retrocrural space. At Johns Hopkins, we do these surgeries with either thoracic or vascular surgeons depending on the location and appearance of the tumor.
Two of the leading centers in the treatment of advanced testicular cancer, Indiana University and Memorial Sloan Kettering Cancer Center in New York, presented their experiences with retrocrural metastases. In both series, the majority of tumors were teratoma. A variety of incisions were described, with the most common being an abdominal approach with trans-diaphragmatic access when necessary. Both centers prescribed to joint surgery involving both urology and thoracic surgery. At Johns Hopkins, we do these surgeries with either thoracic or vascular surgeons depending on the location and appearance of the tumor.
