Low-cord orchidectomy for testicular cancer: what would be different?

Abstract

IntroductionHigh cord radical orchidectomy (HRCO) is accepted as the standard surgical approach in testicular cancer, however low cord orchidectomy (LCRO) can reduce the morbidity of operation without worsening the oncological outcomes.MethodsWe retrospectively re-examined the specimens of men to determine the level of spermatic cord invasion (SCI). Men who had proximal SCI with negative surgical margins after HRCO were assumed to have de-novo residual tumour if LCRO was performed. Others were assumed as oncologically similar. We examined the relation between pre-operative variables and SCI and proximal SCI to determine whether prediction of proximal SCI is possible.Results196 patients were included. 22 (11%) had SCI and ten (5%) had proximal SCI. Four patients with proximal SCI had positive surgical margins even after HRCO and didn’t require additional local treatment. Six patients were assumed to have de-novo residual tumour if LCRO was performed. All six patients were metastatic and had systemic chemotherapy. High platelet count, tumour size, N stage, S stage and M stage were all significantly related with both SCI and proximal SCI (p < 0.05).ConclusionDue to low probability of SCI, we think LCRO can safely be performed to reduce morbidity in Stage 1 patients. Although there is a risk for residual tumour in Stage 2–3 patients, currently there is no data that residual tumour would impair the success of systemic chemotherapy. Therefore we can not assume that these patients would be negatively affected. Pre-operative data can be useful to predict the presence of proximal SCI and select appropriate patients for LCRO.
