Among the different options recommended for locally advanced prostate cancer (LAPC), radical prostatectomy (RP) is a relatively infrequent option because its role is still controversial. The results of clinical trials combining an external radiotherapy to a long-term androgen deprivation sustain the principle of a multidisciplinary management of LAPC. Impact of surgery on the risk of progression and local recurrence is important in selected patients with low grade and small tumoral volume. Clinical and histological data associated to the MRI assessment remain essential and enhance the preoperative multidisciplinary decision. Oncological results from recent series show 10-year and 15-year specific survival rates around 85 and 75%, respectively. Moreover, approximately 20 to 30% of patients initially presented with cT3 tumours have finally an organ-confined disease on pathological examination. Morbidity of the procedure is similar to RP for organ-confined tumours despite more erectile dysfunction due to non-sparing RP in most of cases. An enlarged RP with an extended pelvic lymphadenectomy can be considered as a viable alternative to radiotherapy and hormonal therapy in patients with long life expectancy presenting cT3 tumour with a high risk of local progression and a low risk of metastatic disease. Comparative and combined treatments including RP have to be prospectively investigated in clinical trials in terms of oncological outcome and quality of life.
