J Coll Physicians Surg Pak Jan ;28(4):292-6.

Objective: To determine the disease characteristics of testicular germ cell tumor, biochemical/radiological response to chemotherapy and common toxicity profile. Study Design: Case series. Place and Duration of Study: Institute of Nuclear Medicine and Oncology (INMOL), Lahore, from January 2010 to December 2013. Methodology: Fifty-one patients with histologically proven testicular germ cell tumor, who fulfilled the pre-defined eligibility criteria, were selected. Presenting symptoms and disease stage were studied. Patients were staged according to the AJCC 2010 staging criteria and prognosis was classified according to the IGCCCG Classification of Metastatic Germ Cell Cancer. Initial chemotherapy treatment was based upon the International Germ Cell Consensus Classification, 1997. Patients were also evaluated for chemotherapy-induced toxicity based on Common Toxicology Criteria version 4. SPSS version 16.0 was used for statistical analysis. Results: Main presenting symptoms included testicular pain (37.3%), testicular swelling (25.5%), and abdominopelvic pain (11.8%). Most of the patients had mixed germ cell histology (p <0.001) and presented with advanced disease stage. Out of 51 patients, 41 (80.3%) achieved complete clinical remission after first line chemotherapy. All patients having complete response achieved 2-year survival and 37 (90.2%) had no evidence of recurrent disease. Four patients with recurrent disease achieved complete remission with second line chemotherapy. Five (9.8%) had partial response after first line chemotherapy while 2 (3.9%) progressed on treatment. All patients developed alopecia, 21 (41.1%) experienced other toxicities which were managed symptomatically and with minor dose modifications. Conclusion: Many patients with germ cell tumors presented with pain, and in an advanced stage, with mixed histology. Overall response rate was 90.2% with platinum-based chemotherapy.
