RESULTSThe prostate-specific antigen (PSA) level decreased to < 0.5 ng/mL in 79% of patients undergoing primary treatment and in 67% of patients undergoing salvage treatment. A higher Gleason grade and PSA levels were associated with a poorer outcome. No patient developed a fistula, 4% developed urinary retention requiring transurethral prostatectomy and 4% had persistent incontinence. The rates of erectile dysfunction were high (86%). The median inpatient stay was 2 days. CONCLUSIONEarly results suggest that cryotherapy offers a safe alternative for primary and recurrent prostate cancer, particularly for older and less fit patients. Long-term data are required to assess the durability of response and the effect on survival.

There is no consensus as to the management of untreated poor prognosis or relapsed/refractory germ cell tumours. We have studied an intensive cisplatin-based regimen that incorporates high-dose methotrexate (HD MTX) and actinomycin-D and etoposide every 14 days (GAMEC). Sixty-two patients were enrolled in a phase 2 study including 27 who were untreated (IGCCCG, poor prognosis) and 35 with progression despite conventional platinum based chemotherapy. The pharmacokinetics of the drugs were correlated with standard outcome measures. Twenty of the untreated patients were progression free following GAMEC and appropriate surgery, as were 18 individuals in the pretreated group. None of the established prognostic factors for therapy for pretreated patients could identify a poor-prognosis group. Five out of nine late relapses to prior chemotherapy were progression free following GAMEC and appropriate surgery. All patients had at least one episode of febrile neutropenia and there were five (8%) treatment-related deaths. PK values were not predictive of efficacy or toxicity, although the dose intensity in the pretreated group of patients, especially of HD MTX, was significantly correlated with progression-free survival (PFS). GAMEC is a novel intensive regimen for this group of patients producing encouraging responses, although with significant toxicity. For those in whom it fails, further therapy is still possible with durable responses being seen.

IntroductionTissue cryoablation is a potential curative option for solid malignancies, including radiation recurrent prostate cancer (RRPC). Case series of salvage cryotherapy (SCT) in RRPC have reported promising disease free survival (DFS) outcomes and acceptable toxicity profile. While many men receive SCT, no predictive factors for treatment induced side effects are known. The aim of this study is to validate the oncologic outcome of SCT in a large multi-centre patient cohort and to identify potential parameters associated with an increased risk of micturition symptoms.Patients and MethodsIn this retrospective analysis, we studied 283 consecutive patients with RRPC treated by SCT in three independent U.K. centres (between 2001 and 2011). Two freeze-thaw cycles of transperineal cryotherapy were performed under transrectal ultrasound guidance by a single surgeon in each of the 3 sites. We analysed clinico-pathological factors against tumour response. Functional outcomes were assessed by continence status and IPSS questionnaire. Predictive factors for SCT-induced micturition symptoms were analysed in a sub-group (n = 42) of consecutive cases.ResultsWe found that nadir post-SCT PSA levels strongly associated with DFS. The DFS rates at 12- and 36-month were 84% and 67% for the ≤1 ng/ml group and 56% and 14% for the >1 ng/ml group, respectively (p<0.001). Correlative analysis revealed highly significant association between patients' post-SCT micturition status with prostate gland and iceball lengths following SCT. Finally, in a reduction model, both gland length and maximal length of iceball were highly associated with patients' IPSS outcome (p<0.001).ConclusionWe report the largest European patient cohort treated with SCT for RRPC. Oncologic outcome guided by nadir PSA of <1 ng/ml is consistent with earlier single-centre series. For the first time, we identified physical parameters to predict micturition symptoms following SCT. Our data will directly assist on-going and future trial design in cryotherapy in prostate cancer.

OBJECTIVE To evaluate prospectively the sexual function of patients undergoing cryosurgery as a primary radical treatment for localized prostate cancer, as the development of 17 G cryotherapy probes has improved the delivery of this treatment, but one of the side‐effects of cryosurgery is the development of erectile dysfunction (ED). PATIENTS AND METHODS Between July 2003 and May 2008, 53 patients were treated using an argon‐based third‐generation cryotherapy system (Oncura, Arlington Heights, IL, USA). Prospective data were collected at 6 weeks, 3 months, then 3‐monthly up to 1 year and subsequently 6‐monthly. Patients were followed up for up to 54 months, with a median (mean) follow‐up 36 (30.5) months. RESULTS All 53 patients were followed after receiving cryosurgery as primary treatment for prostate cancer; 51 (96.3%) had ED at 6 weeks while two (3.7%) were experiencing partial erections. By 9 months one (2.4%) of 42 patients was fully potent using phosphodiesterase type‐5 inhibitors, and six (14.3%) were experiencing partial erections. By 18 months eight (21%) of 39 patients followed up had regained full potency and by 24 months eight (24%) of 33 patients were fully potent and three (9%) experienced partial erections. CONCLUSION While ED is a significant side‐effect of cryotherapy, a considerable proportion of patients who have no ED before treatment (39%) recover full sexual function afterward. Focal nerve‐sparing cryosurgery might be the way forward in an attempt to preserve erectile function in men who had no ED before treatment. Erectile aids should be made available for those patients for whom sexual dysfunction compromises the quality of their life and relationships.
