| Abstract |
We have assessed 24 patients consecutively treated with cryosurgery and chosen according to the guidelines of the European Study Group of Urologic Cryosurgeons. Of the 24 patients (average age about 70, range 61-79), all were not considered candidates for radical prostatectomy, 9 (37%) were clinical stage cT2 N0M0, 15 (63%) cT3 N0M0 who had not received any prior treatment, except 1 patient (61 years old) who was treated with TCT and successive recurrence of the disease (cT2). Of the 24 chosen patients, 13 (55%) were over the age of 71, 11 (45%) had important factors of co-morbidity and an elevated risk of surgery (ASA 3). The average PSA was of 19.3 ng/ml (range 2.2-61). Gleason score was 2-5 in 9 cases, 6-7 in 14 and 8-10 in 1 case. In the follow-up, we evaluated serum PSA every 3 months and transrectal ultrasound and the echoguided prostatic biopsies at 6, 12 and 24 months. Post-operative complications included: ecchymosis and edema of external genitals (16/24), fever > 38 degrees C (1/24), sloughing syndrome (6/24), urinary tract infections (10/24) acute urine retention (1/24). In 2 cases, 6 months after treatment, a transrectal resection was carried out. After a follow-up at 6 months, the PSA was 0.4 ng/ml (range 0.1-0.9), in 1 case. In positive core biopsy out of 6 showed neoplastic cells with fibrous tissue; the patient had a PSA of 0.58 ng/ml. At 12 months there were 11 assessable patients. The average PSA was 0.3 ng/ml (range 0.1-0.9). At 24 months there were 4 assessable patients, 1 of 4 showed serum PSA level of 4 ng/ml and cancer in apical biopsy. Erectile dysfunction was assessed on 8 patients affective before surgery: 1 referred to sufficient erections at penetration (1/8, 12.5%). After removal of the catheter, 4 of the 20 patients suffered stress and urge incontinence with the use of 1 pad a day. In 1 case, 18 months from surgery, slight stress incontinence was found (1 pad/day). Cryoablation is an efficient method and is given to slight post-operative morbidity and no intra-operative mortality, also in patients with high risk for open surgery. Indications may be found in patients with the following conditions: older than 72 years, severe co-morbidity and high risk for surgery, neoplasia at high risk of progression, and disease recurrence after radiotherapy. Our case history is at the moment encouraging and a larger number of cases as well as longer follow-up are needed.
