ABSTRACT
Background: Testicular cancer represents between 1% and 1.5% of neoplasms in men and 5% of the urological tumors. It is the most frequent cancer in men between the ages of 15 and 45 years. Ninety-five percent of testicular tumors are composed of malignant germ cells and only 5% are bilateral. Currently, there is a 95% cure rate for low stage testicular cancer. The percentage is lower for more advanced tumors. Early and interdisciplinary treatment including chemotherapy, radiotherapy and surgery are factors attributing to the high cure rate.
Objective: To determine the testicular cancer survival rate.
Materials and methods: A survival analysis crosssectional study was carried out. Case records of all patients diagnosed with testicular cancer from January 1989 to October 2007 were reviewed. Multiple variables were analyzed. Descriptive statistics, survival analysis and proportional Kaplan-Meier and Cox curves were employed. Statistical significance was considered when
P ≤ 0.05.
Results: From a total of 307 patients, 184 met the study inclusion criteria. Mean age was 29 years. There were 25 deaths over an 18-year period and the general survival rate was 86%. Ninety-six percent of patients presented with germ cell tumors, 44% with seminomatous tumors and 56% with non-seminomatous tumors. In relation to disease stage, percentage results were as follows: 1a (33.5%), 1b (11%), 1c (15.5%), 2a (6%), 2b (7%), 2c (9%), 3a (3%), 3b (6.5%) and 3c (8.5%). A total of 81.5% of patients were in the good prognosis category, 12.5% in the intermediate category and 6% in the poor prognosis category. The survival rate was lower in the intermediate and poor prognosis groups with
p ‹ 0.01. A total of 40.5% of patients were left in observation, 47.5% were given chemotherapy, 7.5% were given radiotherapy and 4.5% underwent chemotherapy and radiotherapy.
Conclusions: In contrast to the national and international literature, testicular cancer is the second most common cancer seen in medical consultation in our hospital. The majority of patients have a favorable progression that is principally dependent on the histology, stage and risk factors of their disease.
