RESUMO

Purpose: Radical surgery is the preferred method for local high-risk and limited progressive prostate cancer in the routine clinical setting. However, current guidelines do not recommend neoadjuvant hormone therapy (NHT). Opinions regarding NHT vary among individual clinicians. According to the experience gained at our center, we explored the benefits of NHT for patients with prostate cancer during the perioperative period in this study. Methods: In this retrospective study, we explored the perioperative benefits of NHT among 189 patients with local high-risk or limited progressive prostate cancer who underwent radical prostatectomy and divided them into two groups: the NHT group and the non-NHT group. The NHT regimens were a gonadotropin-releasing hormone (GnRH) agonist alone (3.75/11.25 mg of leuprolide or 3.6/10.8 mg of goserelin acetate), an androgen receptor antagonist (ARA) alone, or a combination of the two. The duration of treatment was <3 months, 3 to 6 months, or >6 months. Results: We found that NHT could reduce the surgery time and intraoperative hemorrhage, thus reducing the difficulty of surgery; NHT could also improve the postoperative recovery of patients. However, it did not reduce the stage of prostate cancer or positive surgical margin rate. Conclusions: Neoadjuvant therapy is optional for some patients. We believe that NHT will improve the overall prognosis of patients as progress continues in the medical field in the future.

RESUMO

We aim to develop a nomogram to predict re-operation due to secondary hemorrhage after Monopolar transurethral resection of the prostate (M-TURP). We identified patients undergoing M-TURP at Peking University First Hospital from 2000 to 2013. Univariate and multivariate logistic regression models were developed to predict the occurrence re-operation due to secondary hemorrhage. The discriminatory ability of the nomogram was tested using the area under the receiver operating characteristic curve (ROC), and internal validation was performed via bootstrap resampling. Of the 1901 patients who underwent M-TURP during the study period, 9.1% (173 patients) experienced hemorrhage after M-TURP, and they had a 22.0% re-operation rate (38 patients). Benign prostatic hyperplasia (BPH)-related complications (odds ratio, 0.386; 95% CI, 0.177-0.841), percent of resected prostate (OR, 0.156; 95% CI, 0.023-1.060) and suprapubic cystostomy (OR, 0.298; 95% CI, 0.101-0.881) were independently associated with re-operation. The nomogram accurately predicted re-operation (area under the ROC curve 0.718). The negative predictive value was 88.0%, while the positive predictive value was 47.9%. Re-operation due to secondary hemorrhage after M-TURP was associated with no BPH-related complications, lower percent of resected prostate and no suprapubic cystostomy and was accurately predicted with using the nomogram.

RESUMO

We aim to reassess the safety of the monopolar transurethral resection of the prostate (M-TURP) without suprapubic cystostomy at our institution over the past decade. This retrospective study was conducted in patients who underwent M-TURP at Peking University First Hospital between 2003 and 2013. A total of 1680 patients who had undergone M-TURP were identified, including 539 patients in the noncystostomy group and 1141 patients in the cystostomy group. After propensity score matching, the number of patients in each group was 456. Smaller reductions in hemoglobin and hematocrit (10.9 g vs 17.6 g and 3.6% vs 4.7%, respectively) were found in the noncystostomy group. In addition, patients undergoing surgery without cystostomy had their catheters removed earlier (4.6 days vs 5.2 days), required shorter postoperative stays in the hospital (5.1 days vs 6.0 days), and were at lower risk of operative complications (5.7% vs 9.2%), especially bleeding requiring blood transfusion (2.9% vs 6.1%). Similar findings were observed in cohorts of prostates of 30-80 ml and prostates >80 ml. Furthermore, among patients with a resection weight >42.5 g or surgical time >90 min, or even propensity-matched patients based on surgical time, those with cystostomy seemed to be at a higher risk of operative complications. These results suggest that M-TURP without suprapubic cystostomy is a safe and effective method, even among patients with larger prostates, heavier estimated resection weights, and longer surgical times.

RESUMO

OBJECTIVE: To investigate the perioperative parameters and postoperative sexual function and complications in native Tibetans undergoing transurethral resection of the prostate (TURP) for BPH with different prostate volumes. METHODS: From June 2015 to February 2017, 325 native Tibetans with BPH underwent TURP in the People's Hospital of Tibet Autonomous Region. The patients were aged 59-88 years, with a median oxygen saturation level of 84% in the normal status, 24% with hydronephrosis, 40.3% with the history of acute urinary retention, 61.8% with pulmonary hypertension, and 19.1% taking regular medication preoperatively. According to the preoperative prostate volume (PV), the patients were divided into a large PV (LPV) group (PV ≥80 ml, n = 124) and a small PV (SPV) group (<80 ml, n = 201). Perioperative parameters and postoperative sexual function and complications were analyzed and compared between the two groups of patients. RESULTS: The operation time was significantly longer in the LPV than in the SPV group (ï¼»92.36 ± 26.35ï¼½ vs ï¼»56.28 ± 24.61ï¼½ min, P < 0.05) and the intraoperative blood loss was higher in the former than in the latter (ï¼»401.12 ± 50.12ï¼½ vs ï¼»385.15 ± 51.62ï¼½ ml, P < 0.05). Compared with the baseline, at 6 months after operation, the IPSS was significantly decreased in all the patients (22.13 ± 6.23 vs 5.29 ± 1.14 in the LPV group, P < 0.05; 23.04 ± 6.82 vs 5.12 ± 1.28 in the SPV group, P < 0.05), and the maximum urinary flow rate (Qmax) remarkably improved (ï¼»17.46 ± 5.82ï¼½ vs ï¼»5.91 ± 1.86ï¼½ ml/s in the LPV group, P < 0.05; ï¼»17.99 ± 5.86ï¼½ vs ï¼»6.01 ± 1.92ï¼½ ml/s in the SPV group, P < 0.05). The incidence rate of retrograde ejaculation was markedly higher in the LPV than in the SPV group postoperatively (48.4% vs 20.9%, P < 0.05). No statistically significant differences were observed between the two groups of patients in the incidence of postoperative complications (13.71% vs 9.45%, P > 0.05). CONCLUSIONS: TURP is effective and safe for the treatment of BPH native Tibetans with different prostate volumes.

RESUMO

We aim to investigate the correlation of benign prostatic obstruction (BPO)-related complications with clinical outcomes in patients after transurethral resection of the prostate in China. We reviewed the medical history of all patients who underwent surgery from 1992 to 2013. We assessed the preoperative clinical profile, clinical management, and operative complications. Overall, 2271 patients were enrolled in the study. Of these patients, 1193 (52.5%) had no BPO-related complications and 1078 (46.3%) had BPO-related complications. Compared with patients without BPO-related complications, those with BPO-related complications were older (p = 0.001) and usually had other urologic comorbidities (p = 0.003). Additionally, they tended to have more tissue resected (p < 0.001), a higher American Society of Anesthesiologists grade (p = 0.002), and larger prostates (p < 0.001). Nonetheless, there was no obvious difference in surgical complications between both groups (p > 0.05). Among patients with BPO-related complications, compared with the bladder stone group, only the bladder stone+ group tended to have a greater urinary infection risk after transurethral resection of the prostate. Compared with patients with one or two BPO-related complications, those with three BPO-related complications tended to have a higher risk of pulmonary embolism and acute coronary syndrome (p < 0.05). Despite the widespread use of medication, patients with BPO-related complications were older and had larger prostates; however, transurethral resection of the prostate is still considered a safe and recommended surgical treatment. Nevertheless, those with three or more complications were at a higher risk of severe complication after surgery, and active surgical intervention is needed once BPO-related complications develop.

RESUMO

OBJECTIVE: To compare the diagnostic accuracy of five internationally used indolent prostate cancer screen protocols in Chinese prostate cancer patients. METHODS: Retrospective analysis was made of the consecutive cohort of 314 patients, from Jan. 2006 to Apr. 2014, who had both prostate biopsy and radical prostatectomy in Peking University First Hospital. The Gleason score≤6, pT2, tumor volume≤0.5 mL, margin negative and lymph nodes negative were defined as indolent prostate cancer. The predictive value of five indolent screen criteria including Epstein, Memorial Sloan-Kettering Cancer Center (MSKCC), Prostate Cancer Research International: Active Surveillance (PRIAS), University of California, San Francisco (UCSF), and University of Miami (UM) were evaluated in Chinese prostate cancer patients. Measures of diagnostic accuracy and areas under the receiver-operating curve (AUC) were calculated for each protocol and compared. RESULTS: A total of 16% (49 cases) of the patients met the inclusion criteria of at least one protocol, including 24 cases in Epstein, 33 cases in MSKCC, 28 cases in PRIAS, 34 cases in UCSF, and 22 cases in UM. Three percent were eligible for all the studied criteria. UCSF and MSKCC protocols had the highest sensitivity and specificity than the others. The Epstein and PRIAS protocols demonstrated acceptable positive predictive value, but the specificity and sensitivity were inefficient. The UM protocol was performed unsatisfiedly on sensitivity, positive predictive value and AUC. A strict limited protocol which contained all the five protocols could not improve the predictive accuracy. CONCLUSION: The UCSF protocol had better diagnostic accuracy than the others, but the results were not satisfied. A further investigation on indolent prostate cancer screening in Chinese patients is needed.

RESUMO

OBJECTIVE: To identify the risk factors that would aid in the identification of patients at the greatest risk of developing postoperative paralytic ileus. METHODS: In the retrospective study, 749 patients who received radical cystectomy from January 2005 to August 2014 were reviewed, of whom, 9 who received orthotopic ileal neobladder were excluded. Of the 740 patients, 82 (11.1%) developed postoperative paralytic ileus. The correlation between the clinical characters and the occurrence of post-operative paralytic ileus was identified. RESULTS: The postoperative paralytic ileus was significantly correlated with the patient's age (68 vs. 67, P=0.025), body mass index (23.0 kg/m2 vs.24.1 kg/m2, P=0.008), different urinary diversion reconstruction methods [13.2% (66/500) for ileal conduit and 7.3%(16/240) for cutaneous ureterostomy, P=0.008] and pelvic lymph node dissection [12.2% (77/632) vs.4.6% (5/108), P=0.021].The postoperative paralytic ileus caused a prolonged hospital stay and delayed recovery (24 d vs. 17 d, P=0.000). There was no significant correlation between the postoperative paralytic ileus and the patients' gender, previous abdominal operations, preoperative hemoglobin and creatinine, American Society of Anesthesiologists score, operative time, estimated blood loss, transfusion requirement, laparoscopic and open surgery, ICU admission or tumor staging. On multivariate analysis, age (hazard ratio 1.185, 95% confidence interval 1.036-1.355, P=0.013), body mass index (hazard ratio 0.605, 95% confidence interval 0.427-0.857, P=0.005), different urinary diversion reconstruction methods (hazard ratio 2.422, 95% confidence interval 1.323-4.435, P=0.004) and pelvic lymph node dissection (hazard ratio 2.798, 95% confidence interval 1.069-7.322, P=0.036) were significantly correlated with the presence of the postoperative paralytic ileus. CONCLUSION: Increasing age, decreasing BMI, ileal conduiturinary diversion and pelvic lymph node dissection were significantly correlated with the presence of postoperative paralytic ileus in patients undergoing radical cystectomy.
