Quality of Life After Open or Robotic Prostatectomy, Cryoablation or Brachytherapy for Localized Prostate Cancer

PURPOSEnHealth related quality of life concerns factor prominently in prostate cancer management. We describe health related quality of life impact and recovery profiles of 4 commonly used operative treatments for localized prostate cancer.nnnMATERIALS AND METHODSnBeginning in February 2000 all patients treated with open radical prostatectomy, robot assisted laparoscopic prostatectomy, brachytherapy or cryotherapy were asked to complete the UCLA-PCI questionnaire before treatment, and at 3, 6, 12, 18, 24, 30 and 36 months after treatment. Outcomes were compared across treatment types with statistical analysis using univariate and multivariate models.nnnRESULTSnA total of 785 patients treated between February 2000 and December 2008 were included in the analysis with a mean followup of 24 months. All health related quality of life domains were adversely affected by all treatments and recovery profiles varied significantly by treatment type. Overall urinary function and bother outcomes scored significantly higher after brachytherapy and cryotherapy compared to open radical prostatectomy and robotic assisted laparoscopic radical prostatectomy. Brachytherapy and cryotherapy had a 3-fold higher rate of return to baseline urinary function compared to open radical prostatectomy and robotic assisted laparoscopic radical prostatectomy. Sexual function and bother scores were highest after brachytherapy, with a 5-fold higher rate of return to baseline function compared to cryotherapy, open radical prostatectomy and robotic assisted laparoscopic radical prostatectomy. All 4 treatments were associated with relatively transient and less pronounced impact on bowel function and bother.nnnCONCLUSIONSnIn a study of sequential health related quality of life assessments brachytherapy and cryotherapy were associated with higher urinary function and bother scores compared to open radical prostatectomy and da Vinci prostatectomy. Brachytherapy was associated with higher sexual function and bother scores compared to open radical prostatectomy, robotic assisted laparoscopic radical prostatectomy and cryotherapy.

Single Center Experience with Third-Generation Cryosurgery for Management of Organ-Confined Prostate Cancer: Critical Evaluation of Short-Term Outcomes, Complications, and Patient Quality of Life

BACKGROUND AND PURPOSEnTechnical refinements such as improved ultrasonographic localization and the routine use of urethral warmers and small-gauge needle delivery systems have renewed interest in cryosurgical treatment as a minimally invasive option for selected patients with localized prostate cancer. Only three reports of quality of life (QoL) in prostate cryoablation exist, and none report on patients treated with third-generation cryoablative technology. We critically examine our initial series of consecutive patients at a single institution undergoing primary third-generation cryosurgical treatment of localized prostate cancer with respect to treatment outcome, morbidity profile, and QoL parameters. To our knowledge, this is the first QoL report on third-generation cryoablation of the prostate.nnnPATIENTS AND METHODSnWe retrospectively review the records of 89 consecutive patients with median followup of 11 months (1-32) who have undergone third-generation cryosurgical ablation of the prostate as primary treatment for localized prostate cancer with intention to cure. Patients were risk stratified according to preprocedural parameters of prostate-specific antigen (PSA), clinical stage, and Gleason score. PSA trends were recorded and treatment effectiveness was observed using different definitions of biochemical failure. Charts were reviewed for postprocedure complications. Quality of life was measured prospectively using the University of California, Los Angeles, Prostate Cancer Index as well as American Urological Association symptom scores. We compare a percent of baseline score (%BS) for various domains between our series of patients treated with primary cryoablation with a series of patients undergoing brachytherapy for localized prostate cancer.nnnRESULTSnTreatment success was defined by achievement of a PSA nadir of < or =0.1 ng/mL and by biochemical disease-free survival (BDFS) assessed with both a PSA threshold of < or =0.4 ng/dL over time and the American Society for Therapeutic Radiology and Oncology (ASTRO) definition of three consecutive rises in PSA. According to risk stratification, 86%, 81.5%, and 78% of low-, intermediate-, and high-risk patients, respectively, achieved a PSA nadir of < or =0.1 ng/mL. Overall, at 12 months follow-up, 94% of patients achieved BDFS using ASTRO criteria while 70% achieved BDFS using a PSA threshold of < or =0.4 ng/mL. With risk stratification, 74%, 70%, and 60% of low-, intermediate-, and high-risk patients, respectively, achieved BDFS defined by PSA threshold of < or =0.4 ng/mL. Complications were rare. The response rate for Health Related Quality of Life (HRQoL) questionnaires was 71% for cryoablation patients and 51% for brachytherapy patients. At 12 months follow-up, patients undergoing cryoablation on average achieved urinary and bowel domain scores comparable to baseline, but sexual domains remained well below baseline. When compared with a brachytherapy series with better baseline sexual function (P = 0.04) and urinary function (P = 0.03), cryotherapy patients experienced more negative impact on sexual function steadily for up to 12 months (P = 0.02). Urinary function was similar between the groups until 18 months, at which time cryoablation patients fared better (P = 0.01); this was sustained up to 24 months (P = 0.04).nnnCONCLUSIONSnTreatment success with cryosurgery varies with definition; however, our results are comparable to other series with regard to short-term cancer control. Complication rates in this series of third-generation cryosurgical patients are low. QoL characteristics of third-generation cryoablation are similar to those described in second-generation cryoablation series. Compared with brachytherapy, cryotherapy results in less irritative and obstructive voiding symptoms in the early post-treatment period and may improve urinary function up to 24 months after treatment. In a small group of older patients with baseline erectile dysfunction undergoing cryoablation, sexual function returns to 20% of its baseline value with up to 12 months follow-up.

Single Center Experience with Percutaneous and Laparoscopic Cryoablation of Small Renal Masses

BACKGROUND AND PURPOSEnWhile partial nephrectomy remains the gold standard for the management of most small renal masses, increasing experience with renal cryoablation has suggested a viable alternative with a favorable morbidity profile and good efficacy. We report intermediate-term oncologic outcomes from a single-center experience with laparoscopic and percutaneous renal cryoablation.nnnPATIENTS AND METHODSnWe performed a retrospective review of our laparoscopic renal cryoablation (LRC) and percutaneous renal cryoablation (PRC) experience between January 2003 and April 2007. Patients with at least 12 months of follow-up were included in the analysis. Follow-up consisted of imaging and laboratory studies at regular intervals. Persistent mass enhancement or interval tumor growth was considered a treatment failure.nnnRESULTSnSixty-six patients (44% women/56% men; 42% African-American/58% Caucasian/other; mean body mass index, 29.7) with 72 tumors underwent either LRC (n = 52) or PRC (n = 20) with a mean follow-up of 30 months (median 25.1 mos; range 13-63 mos). Average patient age was 66.5 years (range 34-82 yrs). Mean tumor size was 2.33 cm (range 1-4.6 cm). Comorbid conditions were prevalent: 76% hypertension, 36% hyperlipidemia, 24% chronic kidney disease, 29% diabetes mellitus, 36% tobacco use, and 32% heart disease. RESULTS of pretreatment biopsy were 62% renal-cell carcinoma and 38% benign or nondiagnostic. Overall cancer-specific and cancer-free survival were 100% and 97%, respectively. There were two treatment failures (3.8%) in the LRC group and five primary failures in the PRC group (25%) (P = 0.015), four of which were salvaged with repeated PRC with no evidence of recurrence at 6 to 36 months of follow-up. There has been no significant local or metastatic progression.nnnCONCLUSIONSnLRC and PRC achieved good oncologic control with minimal morbidity at a mean follow-up of 30 months in a patient cohort characterized by numerous comorbid conditions. PRC had a significantly higher primary treatment failure rate than LRC, but re-treatment offered salvage oncologic control with no significant complications.

Posterior Reconstruction Before Vesicourethral Anastomosis in Patients Undergoing Robot-Assisted Laparoscopic Prostatectomy Leads to Earlier Return to Baseline Continence

INTRODUCTIONnReapproximation of Denonvilliers fascia adjacent to bladder neck to the rectourethralis, or posterior reconstruction (PR), has been suggested to improve continence in postprostatectomy patients. We examined the impact of the PR on postoperative urinary and other quality-of-life (QoL) outcomes in patients undergoing robot-assisted laparoscopic prostatectomy (RALP).nnnMETHODSnWe identified 89 patients who underwent RALP for prostate cancer between 2006 and 2009 by a single surgeon (R.G.), consented to participate in our prospective QoL study, which collects RAND-UCLA QoL and AUA symptom scores for all patients undergoing treatment for prostate cancer, and completed a baseline and a 3- or 6-month questionnaire. Of these, 31 patients had PR before vesicourethral anastomosis. We compared return to baseline function percentage at 3 and 6 months by PR group. Differences found in univariate analysis were further investigated using multiple linear regression models adjusting for demographics, clinical variables, and nerve-sparing status.nnnRESULTSnWhile most patients had both 3- and 6-month follow-up (n = 74, 83%), sample size at 3 months was n = 86 and at 6 months was n = 77. Groups were comparable by preoperative characteristics, pathologic stage, nerve-sparing status, and baseline QoL/AUA symptom scores. At 3-months, there was a statistically significant improvement comparing PR to non-PR groups in return to baseline score for urinary bother (72% vs. 53%; p = 0.008) and urinary function (64% vs. 50%; p = 0.05), as well as change in absolute AUA symptom score (+0.2 vs. +3.8; p = 0.005). Differences in urinary bother (+20%; 95% confidence interval 5%, 34%) and AUA symptom score (-2.8; 95% confidence interval, -5.4, -0.2) persisted after multivariate adjustment. Groups had similar scores for all parameters by 6 months postprostatectomy.nnnCONCLUSIONSnPR in patients undergoing RALP has a significant impact on early return to baseline parameters relating to urinary bother, urinary function, and AUA symptom score.

Is there correlation of nerve-sparing status and return to baseline urinary function after robot-assisted laparoscopic radical prostatectomy?

BACKGROUND AND PURPOSEnIncontinence is a vital quality-of-life (QoL) concern for men undergoing radical prostatectomy. Using validated QoL instruments, we sought to determine if urinary function was affected by nerve-sparing status at prostatectomy and how this correlated with the three modalities of prostate cancer surgery practiced at our institution: Retropubic radical prostatectomy (RRP), laparoscopic radical prostatectomy (LRP), or robot-assisted laparoscopic radical prostatectomy (RALRP).nnnPATIENTS AND METHODSnPercent of baseline urinary function (PBUF) score was calculated by dividing follow-up urinary function score by baseline urinary function score. Patients with a function score of <30 at baseline (n = 10, 2%) were excluded from analyses. PBUF was compared across categories of nerve-sparing surgery at 3, 6, 12, 18, 24, 30, and 36 months. Survival analysis was conducted classifying a follow-up achievement of 75% percent of baseline score as a successful outcome.nnnRESULTSnOverall, 628 patients were available for analysis. Age, clinical stage, Gleason score, modality of surgery, mean baseline sexual function, and ability to have intercourse significantly affected PBUF. The significance of nerve-sparing status across groups was demonstrated only at 3 months postoperatively. Univariate analysis demonstrated a significant trend of returning to 75% of baseline urinary function in the bilateral nerve-sparing group. Multivariate analysis showed no correlation between type of nerve sparing, type of surgery, and PBUF.nnnCONCLUSIONnPercent return of baseline urinary function is not significantly affected by nerve-sparing status after radical prostatectomy. RALRP demonstrates nonstatistically significant trends of patients returning to baseline urinary function when compared with other modalities.

The Effect of Dutasteride on the Efficacy of Photoselective Vaporization of the Prostate: Results of a Randomized, Placebo-controlled, Double-blind Study (DOP Trial)

OBJECTIVESnTo study the effect of Dutasteride on the efficacy of GreenLight photoselective vaporization of the prostate (PV). Some investigators have suggested that 5 alpha-reductase inhibitors may interfere with PV by reducing intraprostatic blood flow. Dutasteride offers the most complete blockade of the 5 alpha-reductase inhibitors, with minimal increase in side effects.nnnMETHODSnThis is a prospective, placebo-controlled, randomized, double-blind study. A total of 59 patients were randomized to either dutasteride 0.5 mg or placebo for 3 months before and 12 months after PV. Surgical time, joules used, estimated blood loss, and ease of the procedure were compared. Other clinical end points investigated include postsurgical catheter time, hematuria, dysuria, urinary flow parameters, American Urological Association symptom score, benign prostatic hyperplasia quality of life score, prostate volume, and prostate-specific antigen level.nnnRESULTSnAverage surgical time and joules used were 12% (P = .24) and 16% (P = .15) less, respectively, for dutasteride patients compared with placebo. Estimated blood loss was also lower in the treatment group (P = .14). However, these results were not statistically significant. Surgeon-rated ease of the procedure was comparable between the 2 groups. There were no significant differences in catheter time, dysuria, quality of life scores, or urinary flow parameters. Quality of life and urinary parameters markedly improved after PV.nnnCONCLUSIONSnCompared with patients randomized to placebo, patients randomized to dutasteride experienced a trend toward decreased time, joules used, and blood loss during surgery. Although we could not convincingly prove an operative benefit of treatment with dutasteride before surgery, we have demonstrated the efficacy of PV in men receiving dutasteride.
