Feasibility of active surveillance in small testicular mass: a mini review

Abstract

Introduction: Widespread use of scrotal ultrasonography has led to the detection of incidental, non-palpable small testicular masses (STMs). Historically, all intratesticular masses were treated radically, however more conservative strategies are now being applied with growing evidence that up to 80% of STMs are benign lesions. Testis-sparing surgery is deemed a gold standard in STMs. However, the high probability of the benign nature of STMs and the excellent cure rate of localized testicular cancer has led to emerging attempts to use an active surveillance (AS) strategy for selected groups of patients.

Material and methods: We conducted a non-systematic review of the literature in the PubMed and Embase databases for articles associated with AS strategy in STMs.

Results: The main inclusion criteria for AS in patients with STMs were lack of risk factors of testicular cancer, no features of disseminated disease, negative tumor markers, non-palpable lesion that did not exceed 10 mm. Mean follow-up time of AS across the studies ranged from 9.6 to 29.6 months. Surveillance protocols were based on regular physical examination, scrotal ultrasonography and measurement of tumor markers. The change rate to active treatment ranged from 0% to 8% without reported deterioration of oncological outcomes. Patients have proceeded to surgical treatment based on their preference, lesion growth, change in echogenicity, tumor marker growth and the need for testicular exploration for other reasons.

Conclusions: Active surveillance is a reasonable conservative strategy in the management of STMs in selected groups of patients with minimal risk of deteriorating impact on oncological outcomes.
