Objective: Germ-cell neoplasia in situ (GCNIS) is accepted as the precursor of the testicular tumors. The aim in our study is to compare the lymphadenopathy and metastasis parameters in patients diagnosed with testicular tumor with or without GCNIS based on pathological evaluation.


Material and methods: Data from 108 patients who underwent orchiectomy for testicular tumor between January 2007 and December 2014 in our clinic were retrospectively analyzed and included in the study. Patients were divided into two groups based on the pathology reports as GCNIS or not. Groups were compared regarding lymphadenopathy, metastasis, tumor marker levels, tumor size, lymphovascular invasion, rete testis invasion. Mann-Whitney U test was used for statistical evaluation.


Results: Mean age of the patients included in the study were calculated as 34.6±9.3 years. Eighty-five (78.7%) patients had GCNIS, while 23 (21.3%) of them had not. In terms of metastasis, lymphadenopathy, marker levels, tumor size, lymphovascular invasion and rete testis invasion, no statistical significant difference were observed between two groups (p>0.05).


Conclusion: In our study, no statistical significant difference was observed on the prognostic factors concerning the GCNIS entity, which is reported frequently in testicular tumor pathologies. For presently these findings show us that GCNIS cannot be used as a prognostic factor.
