BACKGROUND: Abdominopelvic computed tomography (CT) is widely used in the follow-up of seminoma patients after radical orchidectomy. The aim of this study was to evaluate the clinical utility of abdominopelvic computed tomography in the follow-up of patients with Stage I seminoma.
METHODS: The pathological reports of all patients that have undergone radical orchidectomy in our tertiary referral center between January 2002 and January 2018 have been retrospectively reviewed. All patients with Stage I seminoma and negative serum tumor markers after radical orchidectomy were included. Patients with follow-up shorter than 12 months were excluded. Surveillance records of every patient were reviewed with regard to abdominopelvic imaging.
RESULTS: Of the 133 patients who have undergone radical orchidectomy in our center, 55 had Stage I pure seminoma with normal levels of serum tumor markers after surgery. Two patients were excluded as the follow-up was inadequate. Mean follow-up was 63.2 months (IQR: 30-73). The results of 211 abdominopelvic CTs performed as part of the follow-up were reviewed. Two (3,7%) patients developed recurrence; one consisted of a scrotal lump and was diagnosed with ultrasonography (US) while the second appeared as paraaortic nodal metastasis and was diagnosed with abdominopelvic CT. The recurrence was successfully treated in both patients. A single abdominopelvic CT was useful for the detection of recurrent disease in our entire study population. No cancer specific death has been reported in the study population.
CONCLUSIONS: Follow-up schedules for Stage I seminoma expose patients to potential risks of radiation-induced tumors, emotional distress and represent a significant burden for the healthcare system. The current series suggests that a better risk adapted patient-tailored follow-up program is needed in order to avoid unnecessary investigations.
