This work presents results of the analysis of safety and efficacy of laparoscopic superextended lymphadenectomy, which was performed in patients with clinical progression (the presence of lesions in the lymph nodes of the pelvis and beyond) after undergoing prostatectomy. A feature of the work is that these patients initially extended lymphadenectomy was performed. Clinical detection of foci was carried out by 11C-PET/ CT. Laparoscopic salvage lymphadenectomy appears to be the safe method of performing surgery. When monitoring patients there was evaluated the effectiveness of the operation - the percentage of patients with marked regression and stabilization of markers (PSA), duration of remission. The analysis of the data attempted to determine the predictors of non-response patients after salvage lymphadenectomy.
