Introduction Ninety-five percent of testicular cancers are germ cell tumors with a 5-year survival rate of nearly 95%. Sophisticated surgical techniques, use of tumor markers to guide treatment options, and platinum-based chemotherapy have led to these significantly improved outcomes. Radical inguinal orchiectomy is recommended for suspected testicular cancers to establish the histologic diagnosis in addition to providing definitive treatment. However, tumor spillage at the time of radical orchiectomy (spontaneous vs. iatrogenic) or scrotal violation in the form of transcrotal incision or biopsy can lead to suboptimal local tumor control resulting possibly in higher rates of recurrence, local and distant. In such cases, optimal strategy for salvage therapy is not well defined because of lack of prospective randomized data. Here, in addition to literature review, we report the case of a 51-year-old man who presented with an increasing alpha fetoprotein (AFP) level after radical inguinal orchiectomy despite treatment with the appropriate 1

chemotherapy regimen, who was salvaged successfully with hemiscrotectomy and proximal spermatic cord repeated resection.

Case Presentation A 51-year-old African American man presented with left testicular swelling. He had a computed tomography (CT) scan of the abdomen and pelvis, which showed the left testicular mass and enlarged left periaortic lymph nodes (Fig. 1). The largest was 4.1 cm in diameter. He had a chest x-ray which was normal. Lactate dehydrogenase (LDH) was elevated at 323 IU/L (normal range, 100-248 IU/L). Beta human chorionic gonadotrophin (hCG) was 5.4 mIU/mL (normal range, 0.0-9.9 mIU/mL). AFP was 8.7 ng/mL (normal range, 0.0-9.0 ng/mL). He also had a testicular ultrasound which showed marked enlargement and heterogeneity of the left testicle with microlithiasis. The right testicle was normal. The patient then underwent a left radical orchiectomy. Pathology revealed a 4.6-cm pure seminoma with hemorrhage and necrosis. The tumor extended into the spermatic cord and was present at the spermatic cord margin. There was rupture of the tunica albuginea in an area involved with seminoma and an adherent tumor was present on the inked capsular surface of the testicle. Angiolymphatic invasion was present. There was also peritesticular tissue excised on the left side which was involved with seminoma. The patient’s findings correlated with a pT3 local stage and a clinical stage of IIB. Three weeks after surgery his beta hCG was 12.6 mIU/mL, AFP 6.4 ng/mL, and LDH was 148 IU/L. A repeat surgery was not

recommended at this time. Three cycles of BEP (bleomycin, etoposide, cisplatin) chemotherapy every 3 weeks was recommended. We proceeded with BEP: bleomycin 30 U on day (d)2, d9, and d16, etoposide 100 mg/m2 on d1 to 5, and cisplatin 20 mg/m2 on d1 to 5 for every cycle. After completion of the first cycle, his AFP started increasing and continued to increase to 149.8 ng/mL after the completion of 3 cycles of chemotherapy. His beta hCG and LDH were within the normal range. His CT scan of chest/ abdomen/pelvis was essentially normal (Fig. 2). Positron emission tomography/CT and brain magnetic resonance imaging scans were

also essentially normal. He underwent left groin exploration with left hemiscrotectomy. Final pathology showed necrotic seminoma present with no viable tumor cells identified and a negative proximal margin (Fig. 3). His AFP was 9.4 ng/mL and 6.9 ng/mL after 1 month and 3 months after the hemiscrotectomy, respectively. He was lost to follow-up at that point for a year. After re-establishing care, he was asymptomatic and his tumor markers were normal on subsequent yearly follow-up visits.

Radical inguinal orchiectomy has been recommended as standard of care in the initial management of testicular cancer for nearly 100 years.1 To prevent tumor spillage, exploration is through an inguinal incision which makes en bloc removal of the spermatic cord with a testis enclosed within the intact tunics, technically feasible after early ligation of the spermatic cord.2 Scrotal violation can occur as a consequence of any scrotal or inguinal intervention that leads to tumor spillage which then can result in local seeding, and potentially harbors the route of lymphatic drainage.3 Some of the surgical procedures that could lead to scrotal violation include transcrotal biopsy and transcrotal orchiectomy. In the era of radical inguinal orchiectomy, scrotal violation is still common and in one study the incidence rate was 17% (n ¼ 13).3 Scrotal contamination can occur secondary to scrotal violation leading to tumor spillage resulting from rupture of tumor during its delivery through a suboptimal incision or from spontaneous tumor rupture and spillage as evident in our case. Scrotal contamination and tumor spillage might result in higher rates of local recurrence, an observation based on the historical study conducted in 1925 which reported a local recurrence rate of 24% in patients with testicular cancer after transcrotal orchiectomy.4 A retrospective metaanalysis revealed statistically significant differences in the local

Reshma Khetpal et al recurrence rate among the scrotal violation and inguinal group studies, although no statistical differences in distant recurrence or survival rates in all groups was found.5 However, another report indicates possibly also an increased risk of distant disease.3 Besides guiding treatment strategies, serum AFP and beta hCG are the most sensitive and specific markers for initial diagnosis, staging, predicting recurrence, and prognosis of testicular germ cell tumors.6 Nearly 85% of patients with disseminated testicular germ cell tumors will have increased hCG and/or AFP levels.6 AFP is not secreted by seminoma, so serum elevation of AFP denotes the presence of nonseminomatous elements even if histology is positive for pure seminoma, similar to the patient in our case report. Laboratory error, hepatocellular cancer, and cirrhosis should be considered in differential diagnosis because a false increase level of AFP is very rare.6 Different local treatment options for scrotal violation have been proposed like inguinal node dissection, pelvic lymphadenectomy, scrotal irradiation, and hemiscrotectomy.7-9 These procedures could be potentially disfiguring and disturbing for the patient and have an associated morbidity. Authors from one retrospective study concluded that adjuvant hemiscrotectomy alone does not completely eliminate the risk of local recurrences and it is argued that it might be unnecessary if chemotherapy is given. A critical aspect of local recurrence appears to be the presence of the residual tumor in the scrotectomy specimen.2 In our case study, chemotherapy, which was indicated for his stage of disease, was given to the patient but it appeared to be inadequate to provide the local control presumptively due to the bloodetestis barrier.10 There is a possibility that certain organ sites such as the hemiscrotum and the cord remnant are less sensitive to systemic therapy. These are the sites that should also be considered as sites of relapse in cases of increasing levels of tumor markers with a negative radiographic work-up, especially when other sanctuary sites such as the brain or the contralateral testis are excluded as sites of relapse. Our patients’ serum AFP started increasing during chemotherapy with no radiographic evidence of recurrence, thereby warranting a salvage local therapy in the form of hemiscrotectomy leading to normalization of his serum AFP level with no evidence of disease after 1 year of follow-up. Before the hemiscrotectomy, a discussion among the medical team regarding further second line chemotherapy and the decision was made to treat possible distant resistant disease. However, it was believed that local control was more important because of unique features of his disease (positive margins and tumor spillage).

Based on our literature review, the role of hemiscrotectomy alone is debatable because hemiscrotectomy does not eliminate the risk of relapse. In addition, chemotherapy alone after scrotal contamination decreases the risk of recurrence substantially and the patient might not need hemiscrotectomy. However, these conclusions are based on retrospective studies, which always includes some inherent bias.2,5 Contrary to these observations, our patient needed chemotherapy followed by salvage hemiscrotectomy to render him disease-free. We did not expose him to more salvage chemotherapy considering the toxicities with systemic therapy in addition to resistance due to possible bloodetestis barrier and instead adopted a local approach.

Conclusion Local treatment in cases of gross tumor spillage, especially when positive margins are present, is probably necessary and chemotherapy alone is not a sufficient treatment. Because there are no randomized prospective trials conducted for patients with scrotal contamination and such prospective studies are obviously unlikely to be undertaken, a patient-directed approach is the most prudent strategy.
