A COMPARISON OF CHARACTERISTICS OF SEMINOMAS AND NONSEMINOMAS IN PATIENTS, WHO UNDERWENT RADICAL ORCHIECTOMY FOR TESTICULAR TUMOR

Overview

Characteristics of testicular tumors in a group of 84 patients and a comparison with data form Czech National Cancer Registry and literature.

Aim:
To compare characteristics and treatment results of testicular tumours in our group of patients.

Methods:
Time of follow up, age, duration of symptoms, laterality, clinical stage, treatment modality and its results were evaluated in all patients that underwent radical orchiectomy at our department between 2006 and 2010. Our findings were then compared with information provided in literature

Results:
A total of 87 radical orchiectomies for tumor were performed on 84 patients. Out of these tumors 45 (51.7 %) were seminomas, 37 (42.5 %) were non seminomas and 5 (5.7 %) were lymphomas. The average time of follow-up was 44,9 months (range 18–76 months). The average age of patients with seminoma was 35 years (range 20–77 years) and the average duration of symptoms was 14,8 weeks (1 day – 104 weeks). Out of 45 seminomas, 40 (88.9 %) were in stage I, 4 (8.9 %) in stage II, and 1 (2.2 %) in stage III. Out of 37 treated or observed patients with seminoma, all reached remission. The average age of patients with non-seminoma was 32 years (range 20–59 years) and the average duration of symptoms was 9,5 weeks (1–52 weeks). Out of 37 non seminomas, 20 (54.1 %) were in stage I, 6 (16.2 %) in stage II, 8 (21.6 %) in stage III. Out of 33 treated patients 32 are in remission (96.9 %), 1 patient died of tumor progression.

Conclusion:
Seminomas were present in a slightly higher number of patients whilst nonseminomas were detected in more advanced stages compared to seminomas. The curability of both groups of tumors is similar and altogether good. Our results were comparable with data from other developed countries.

Key words:
Testicular tumor, seminoma, non-seminoma, orchiectomy.
