Active surveillance for patients with localized prostate cancer. Adherence and protocol drop analysis

OBJECTIVE: VA is currently considered the treatment of choice for patients with low and very low risk prostate cancer. We analyzed the evolution of this treatment strategy in our series and adherence to the protocol. MATERIAL AND METHODS: Ambispective study of patients in VA in our center between 2014- 2019. 237 meet inclusion criteria, of which 142 (60%) have a minimum of 12 months of follow- up. Mean age: 68.5 (4678), median PSA 6.37 ng / ml (1-33). 229 (96.6%) are ISUP 1 and 8 (3.4%) ISUP 2. Objectives are proposed to assess our adherence to the protocol. Descriptive statistics are used to communicate the results. RESULTS: According to the classification by risk groups of the NCCN, 145 (61.2%), 49 (20.7%) and 42 (17.7%) were very low risk, low risk and favorable intermediate risk patients, respectively. The median of follow-up is 14 months (0-66). Of the patients with a minimum follow-up of 12 months, 107 (75.4%) were re-biopsied. 80 (33.8%) leave the protocol in these 5 years, 31.3% (25) by their own decision, 55% (44) due to medical criteria, and 11.3% (9) go to WW. After 5 years of follow-up, 99.2% of patients are still alive, 0.8% died of specific non-cancer causes. Of the objectives to assess adherence, 8 are achieved, 1 partially and 1 is not evaluable. CONCLUSIONS: VA in our center is already the treatment of choice for very low-risk patients, with a constant increase from year to year. Adherence to the protocol has been favorable during the period of time studied.
