Health-related quality of life after radical prostatectomy in Japanese men with localized prostate cancer

PURPOSE: We evaluated retrospectively health-related quality of life (HRQOL) after radical prostatectomy (RP) in Japanese men with localized prostate cancer. METHODS: The study was based on self-reported HRQOL of 280 patients. Patients were divided into seven groups: time 0 (T0), baseline before operation; T1, 1-3 months after RP; T2, 4-6 months after RP; T3, 7-12 months after RP; T4, 13-24 months after RP; T5, 25-36 months after RP; and T6, more than 36 months after RP. We measured the general and disease-specific HRQOL using the RAND 36-item Health Survey 1.0 (SF-36) and the University of California, Los Angeles Prostate Cancer Index (UCLA PCI). RESULTS: The general HRQOL of the postoperative groups was assessed by SF-36. The postoperative groups showed almost the same or higher scores than those of the baseline group. Urinary function scores decreased substantially after surgery. In contrast, there was no difference in urinary bother between the baseline and postoperative groups. Sexual function deteriorated substantially in all postoperative groups. Similarly, the sexual bother score significantly deteriorated after RP. The sexual bother score of men aged 65-years or younger was significantly worse than that of their counterparts in the T1-2 groups. CONCLUSION: Despite reports of problems with sexual activity and urinary continence, general HRQOL was mostly unaffected by RP. Although there was a substantial decrease in urinary function, recovery from urinary bother was rapid. Since the deterioration of sexual function was marked through the postoperative period, careful attention should be paid to this issue during preoperative counseling, especially for younger patients.     

Midline extraperitoneal approach to upper urinary tract surgery: Anatomical basis of surgical technique

Aim: To overcome the disadvantages inherent in the standard surgical approach to the kidney, we introduced a novel surgical technique via a midline extraperitoneal approach. The surgical technique is not substantially different from that of the standard midline transperitoneal approach, except no entry is made into the peritoneal cavity. Although the peritoneum itself is extremely thin and fragile, the peritoneum together with underlying subperitoneal fascia can be dissected readily as a substantial layer, if the proper plane is dissected. Further medial mobilization of the peritoneal sac en bloc by pursuing the fusion fascia plane allows full exposure of the kidney, ureter and great vessels. This approach was adopted for consecutive 51 patients during a 10-month period in 2003. All operations, including 33 radical nephrectomies and 11 nephroureterectomies were completed successfully without significant technical difficulties and differences in operation time and estimated blood loss compared to the transperitoneal approach. No intra- or perioperative complication occurred. All patients did seem to have a much more comfortable postoperative period with minor pain and few abdominal complaint, and the clinical impression was that they resumed the physical activity and oral intake earlier than those after the transperitoneal approach (P = 0.056). There are no operation-related problems such as intra-abdominal adhesion or abdominal muscle weakness resulting in some deformity at 2-year or more follow up. This approach combines the advantages of the transperitoneal midline and extraperitoneal flank approach. Its use will undoubtedly reduce the complications inherent in the transperitoneal approach or the flank approach.     

Recovery of health related quality of life after radical prostatectomy in Japanese men: A longitudinal study

BACKGROUND: We performed a longitudinal survey of health related quality of life (HRQOL) after radical retropubic prostatectomy (RP) in Japanese men with localized prostate cancer. METHODS: The present study started with self-reported HRQOL assessments provided by 72 patients who received only RP. The RAND 36-Item Health Survey and the University of California, Los Angeles Prostate Cancer Index were administered before and 3, 6 and 12 months after RP. RESULTS: Patients who underwent RP showed problems in some domains of general HRQOL, but these problems diminished over time. Urinary function declined substantially at 3 months and continued to recover at 6 and 12 months, but scored lower than the baseline. Urinary bother at 3 months had a significant decrease, but at six months it turned out to be the same as the baseline. The data of sexual function and bother showed a substantially lower score after RP. The sexual bother score of the younger men was significantly worse than that of the older men. Those who underwent nerve sparing procedures experienced significantly better recovery of urinary and sexual functions than the non-nerve sparing group. CONCLUSION: Despite reports of problems with sexuality and urinary continence, general HRQOL was mostly unaffected by RP after 6 months. Although there was a substantial decrease in urinary function, recovery from urinary bother was rapid. Deterioration of the sexual domain was remarkable throughout the postoperative period. Therefore, careful attention should be given to preoperative counseling, especially for younger patients.     

Health related quality of life in Japanese men after radical prostatectomy or radiation therapy for localized prostate cancer

BACKGROUND: We performed a retrospective survey of general and disease specific health-related quality of life (HRQOL) after radical prostatectomy (RP) and external beam radiotherapy (XRT) in Japanese men. METHODS: A total of 186 patients underwent RP and 78 underwent XRT for clinically localized prostate cancer between 2000 and 2002. We measured the general and disease specific HRQOL with the MOS 36-Item Health Survey and the University of California, Los Angeles Prostate Cancer Index, respectively. Each treatment group was further divided into four subgroups according to the time scale. RESULTS: Patients from the RP group were significantly younger than those from the XRT group. The tumor characteristics differed significantly in their distributions among the treatment groups. Patients undergoing XRT had low scores in most of the general measures of HRQOL just after treatment, but after 6 months there were no differences between the treatment groups, except for the physical domains. The RP group was associated with worse urinary function, whereas the XRT group had worse bowel function and bother during the first 6 months after treatment. Thereafter, however, urinary and bowel domain did not differ between the groups. Both groups reported poor sexual function, although the RP group scored lower sexual bother. CONCLUSION: The patients who underwent RP had significantly worse urinary and better bowel function than those treated with XRT. Both treatment groups had decrements in sexual function throughout the post-treatment period; careful attention should be paid to this side-effect in preoperative counselling, especially in younger patients, regardless of the primary treatments.     

Impact of hormonal therapy prior to radical prostatectomy on the recovery of quality of life

BACKGROUND: We investigated the changes in health-related quality of life (HRQOL) in patients who underwent prostatectomy (RP) with or without neoadjuvant hormonal therapy (NHT). METHODS: A total of 72 patients undergoing direct RP (DRP group) and 26 patients receiving neoadjuvant hormonal therapy (NHT group) were enrolled in the present study. The baseline interview was conducted before RP (not initiation of therapy). Follow-up interviews were conducted in person at scheduled study visits of 3, 6, and 12 months after surgery. We measured general and disease specific HRQOL with the Medical Outcomes Study 36-Item Short Form and University of California, Los Angeles Prostate Cancer Index, respectively. RESULTS: At baseline, the NHT group scored statistically lower for not only sexual function (P < 0.001), but also the general HRQOL, such as role limitations due to physical problems (P = 0.007), social function (P = 0.045) and mental health (P = 0.034), than the DRP group. The NHT group reported lower scores in social function and mental health at 3 months (P = 0.040 and 0.006, respectively). Patients who received NHT for more than 3 months continued to show significantly lower scores for some HRQOL domains 12 months later. CONCLUSION: Neoadjuvant hormonal therapy may decrease not only sexual function, but also general HRQOL before surgery. The recovery of HRQOL appeared to be further prolonged in patients who received long-term NHT.
