| Popis: | Aim: Testicular germ cell tumors (TGCT) are solid neoplasms common in young adult men and an important cause of cancer-related deaths during this period. Revisions in histopathological classification and staging affect prognosis and treatment. The aim of this study was to analyze our TGCT cases, to review prognostic parameters, and their relationship between germ cell neoplasia in situ (GCNIS), intratubular and intertubular tumors.Material and Methods: In this study, Hematoxylin&Eosin-stained sections of 77 TGCTs were re-evaluated. The presence of GCNIS, intratubular and intertubular germ cell tumors were recorded. Histopathological classification and staging were revised based on the changes in the 8th edition of American Joint Committee on Cancer (AJCC).Results: The majority of the patients were diagnosed as seminoma (n=42), followed by mixed germ cell tumors (n=33) and spermatocytic tumors (n=2). Rete testis invasion in 30 cases, epididymal invasion in 6 cases, hilar soft tissue invasion in 10 cases, tunica vaginalis invasion in 1 case, spermatic cord invasion in 4 cases, and lymphovascular invasion in 22 cases were detected. Intertubular seminoma in 25 cases, intratubular carcinoma in 16 cases, and GCNIS in 73 cases were detected.Conclusion: The major criteria to determine treatment choices are histopathological diagnosis, pathological tumor stage, serum tumor markers and presence of metastasis. According to AJCC 8th edition, addition of hilar soft tissue invasion to staging has increased the number of our pT2 cases. Moreover, assuming discontinuous tumor invasion of spermatic cord by vascular invasion as pM1 has also increased the number of metastatic testis tumors. |
