Non-seminomatous germ cell tumors of the testis. Analysis of AFP and HCG production by primary tumors and retroperitoneal lymph node metastases after PVB combination chemotherapy.
Serum AFP and HCG values were correlated with AFP and HCG tissue staining in 27 non-seminomatous germ cell tumors (NSGCT) of the testis and their retroperitoneal lymph node metastases after PVB chemotherapy. We found a poor correlation between tissue and serum AFP positivity and a moderately good correlation between tissue and serum HCG positivity in the testicular tumor. The therapy-related differentiated teratomatous elements did occasionally produce AFP or HCG, but AFP or HCG were not detectable in the patients' sera. These serum markers have no value for the detection of mature residual tumor following chemotherapy.
