The Impact of Delays to Definitive Surgical Care on Survival in Colorectal Cancer Patients.

INTRODUCTION: Treatment delay may have detrimental effects on cancer outcomes. The impact of longer delays on colorectal cancer outcomes remains poorly described. The objective of this study was to determine the effect of delays to curative-intent surgical resection on survival in colorectal cancer patients. METHODS: All adult patients undergoing elective resection of primary non-metastatic colorectal adenocarcinoma from January 2009 to December 2014 were reviewed. Treatment delays were defined as the time from tissue diagnosis to definitive surgery, categorized as < 4, 4 to < 8, and ≥ 8 weeks. Primary outcomes were 5-year disease-free (DFS) and overall survival (OS). Statistical analysis included Kaplan-Meier curves and Cox regression models. RESULTS: A total of 408 patients were included (83.2% colon;15.8% rectal) with a mean follow-up of 58.4 months (SD29.9). Fourteen percent (14.0%) of patients underwent resection < 4 weeks, 40.0% 4 to < 8 weeks, and 46.1% ≥ 8 weeks. More rectal cancer patients had treatment delay ≥ 8 weeks compared with colonic tumors (69.8% vs. 41.4%, p < 0.001). Cumulative 5-year DFS and OS were similar between groups (p = 0.558; p = 0.572). After adjusting for confounders, surgical delays were not independently associated with DFS and OS. CONCLUSIONS: Treatment delays > 4 weeks were not associated with worse oncologic outcomes. Delaying surgery to optimize patients can safely be considered without compromising survival.

Intracorporeal versus extracorporeal anastomosis for right colectomy does not affect gastrointestinal recovery within an enhanced recovery after surgery program.

INTRODUCTION: Delayed gastrointestinal (GI) recovery remains a significant morbidity after colorectal surgery. Intracorporeal anastomosis for right colectomy may hasten GI recovery. Therefore, the objective of this study was to determine the effect of intracorporeal versus extracorporeal anastomosis on GI recovery after elective laparoscopic right colectomy within an established ERAS program. METHODS: Adult patients undergoing elective laparoscopic right colectomy at a single high-volume institution from 07/2014 to 12/2018 were reviewed. Patients were divided into two groups: intracorporeal (IC) and extracorporeal (EC). The primary outcome was time to GI-3 defined as days to tolerance of solid diet and first flatus/bowel movement. Prolonged postoperative ileus (PPOI) was defined as GI-3 not met by postoperative day 4. Secondary outcomes were length of stay (LOS) and overall 30-day complications. Sensitivity analysis was performed using coarsened exact matching to account for unmeasured confounding. Multiple regression was performed using a Cox proportional hazard model to identify predictors of GI recovery. RESULTS: A total of 346 patients were reviewed, of which 226 were included (71IC, 155EC). Patient characteristics were well balanced between groups: mean age was 64.9 years (SD 15.9), BMI was 26.3 (SD 5.7), 38.1% of patients had ASA ≥ 3, and 78.3% underwent surgery for neoplasms. IC anastomosis was associated with longer operative duration (165 min (SD 40); 144 min (SD 48), p = 0.002). There was no difference in the median time to GI-3 (IC 2 days [IQR1-2]; EC 2 days [IQR2-3], p = 0.135). The incidence of PPOI (IC 8.5%; EC 10.3%, p = 0.659), superficial SSI (4.2% vs. 5.8%, p = 0.757), deep SSI (2.8% vs. 5.2%, p = 0.729), and median LOS (3 days [IQR 2-4] vs. 3 [IQR 3-5], p = 0.059) were also similar. On multivariate analysis, IC anastomosis did not independently predict faster GI recovery (HR 0.98, 95% CI 0.71-1.34). Similar results were observed in the matched cohort (185 patients (61IC, 124EC)). CONCLUSION: In this study, IC anastomosis was not associated with faster GI recovery or reduced complication rate compared to EC anastomosis. Longer term studies may be required to determine the potential benefits of IC anastomosis.

Phenazopyridine: A Preoperative Way to Identify Ureteral Orifices.

OBJECTIVE: To identify difficult to see ureteral orifices (UOs), urologists need a method to stain the urine. Phenazopyridine, a urinary analgesic which discolors the urine orange, can be administered orally preoperatively. We evaluated the usefulness of phenazopyridine in identifying the UOs and optimal timing of administration. METHODS: Adult patients undergoing endoscopic procedures at the Stratton VA were prospectively enrolled. Preoperative metabolic panels were reviewed. Exclusion criteria were renal insufficiency (creatinine clearance <50 mL/min), severe hepatitis or severe liver disease, glucose-6-phosphate dehydrogenase deficiency, previous hypersensitivity to phenazopyridine, or pregnancy. In phase 1, patients undergoing office flexible cystoscopy were administered 200 mg phenazopyridine the morning of the procedure. Because of the robust orange color of the urine, phase 2 was implemented. In phase 2, patients undergoing rigid cystoscopy in the operating room took 200 mg phenazopyridine at 7 PM the night before surgery. Upon entry into the bladder, UOs were identified and urine color was graded (0 = no dye, 1 = weak, 2 = moderate, and 3 = strong). Patients were assessed postoperatively for side effects. RESULTS: Five patients were included in phase 1. The mean time from medication to cystoscopy was 153 minutes (range 17-304 minutes). One-third of patients had excretion of grade 3 orange urine that obscured inspection of the bladder mucosa. The study design was adjusted and we transitioned to phase 2. Twenty-three patients were enrolled in phase 2. The mean time from phenazopyridine dose to cystoscopy was 14 hours (range 13-17 hours). Seventy-three percent of patients had grade 2 efflux from the UOs. CONCLUSION: Phenazopyridine can successfully identify UOs and can be administered as early as the evening before the procedure.

Hematospermia: etiological and management considerations.

BACKGROUND: Hematospermia, or blood in the ejaculate, usually follows a benign self-limiting course. However, it can be a source of considerable anxiety in patients. The purpose of this article is to provide the primary care physician an algorithm for the evaluation and management of hematospermia based on frequency of occurrence and patient age. METHODS: We performed an English language MEDLINE (1966 to present) search for the terms hematospermia, hemospermia, management, prostate biopsy and combinations thereof. We then constructed a management algorithm based on available evidence. RESULTS: Typically, patients present to their primary care physician after a single episode of hematospermia out of concern for malignancy or venereal disease. In men 40 years old or younger, it is most often due to inflammatory or infectious processes. In men over 40 years of age, however, an association exists between hematospermia and more serious underlying pathology. A significant number of cases remain idiopathic even after extensive investigation. CONCLUSIONS: Hematospermia is an anxiety-provoking sign that is usually due to inflammatory or infectious causes. Recurrent or symptomatic hematospermia may herald more serious underlying pathology, especially in those patients over 40 years old. A thorough evaluation is warranted to both rule out more serious pathology and to adequately address patient anxiety. With modern imaging techniques, the number of "idiopathic" cases should be much lower than historically reported.

A case of synchronous bilateral spermatocytic seminoma.

Bilateral testis tumors are rare and the majority of cases are classic seminoma presenting metachronously. We present the only reported case of synchronous bilateral spermatocytic seminoma.

Office based transurethral needle ablation of the prostate with analgesia and local anesthesia.

PURPOSE: We evaluated the efficacy and feasibility of performing office based transurethral needle ablation of the prostate with analgesia and local anesthesia. MATERIALS AND METHODS: A total of 56 consecutive patients underwent transurethral needle ablation of the prostate for symptomatic benign prostatic hyperplasia. Oral rofecoxib (50 mg) and ciprofloxacin (250 mg) were administered before the procedure with 25 mg hydroxyzine and 50 to 100 mg meperidine intramuscularly. A combination of 2% lidocaine solution and jelly was used for anesthesia. Patients rated discomfort during anesthesia administration and the procedure using a 10-point scale of 0--no discomfort to 10--the worst pain/discomfort ever experienced in the patient life. Overall satisfaction with the procedure was assessed with a 4-point scale of 1--very satisfactory to 4--very unsatisfactory. Followup was 12 months for uroflow and 36 months for International Prostate Symptom Score. RESULTS: The mean age of 47 patients was 65.4 years. Mean discomfort ratings were 3.6 and 4.9 for anesthesia administration and the procedure, respectively. Average operative time was 34.4 minutes, excluding anesthesia administration. The mean overall satisfaction score was 1.5. The mean preoperative International Prostate Symptom Score was 23.1, which improved to 10.9, 11.2, 12.3, 13.8 and 11.3 at 3, 6, 12, 24 and 36 months, respectively. Mean maximum uroflow improved from 8.2 ml/sec at baseline to 12.8, 13.9 and 13.3 ml/sec at 3, 6 and 12 months, respectively. CONCLUSIONS: Administration of an intramuscular narcotic combined with oral analgesic and topical lidocaine provided adequate pain control for transurethral needle ablation of the prostate, making it a feasible office procedure.

Impact of prostate-specific antigen level and prostate volume as predictors of efficacy in photoselective vaporization prostatectomy: analysis and results of an ongoing prospective multicentre study at 3 years.

UNLABELLED: In a multicentre study from the USA, 3-year results of the high-power KTP laser prostatectomy are presented. The authors used preoperative PSA level as a marker of prostate volume and assessed its potential predictive value on the level of clinical efficacy for treating symptomatic BPH. They found that the overall results from the technique were positive and durable, and suggested that there was a significant difference in efficacy between patients presenting with a total PSA of <6 or >6 ng/mL. Many patients who have had a radical prostatectomy are followed for a prolonged period and several observations are presented from an Italian study of urinary incontinence. The authors present their detailed results, finding a considerable trend in incontinence and anastomotic stricture, which decreased over time. OBJECTIVE: To report the 3-year results and analyse whether total prostate-specific antigen (tPSA) levels and prostate volume before treatment can predict the level of clinical efficacy of photoselective vaporization prostatectomy (PVP) for treating obstructive benign prostatic disease, as high-power potassium-titanyl-phosphate (KTP) laser prostatectomy was previously shown to be safe and to efficiently vaporize prostatic adenoma secondary to benign prostatic hyperplasia (BPH), with minimal bleeding and morbidity. PATIENTS AND METHODS: From October 2001 to January 2003, 139 men (mean age 67.7 years, sd 8.7) diagnosed with obstructive lower urinary tract symptoms secondary to BPH, had PVP with an average 80 W of KTP laser energy, at six investigational centres. A subanalysis evaluating each patient for tPSA and prostate volume before PVP was conducted, with a long-term assessment of the primary efficacy outcomes at 3 years after PVP. Each patient was assigned to one of two subgroups according to the tPSA level (group 1, < or = 6.0 ng/mL; group 2 > or = 6.1 ng/mL) and evaluated separately. Each subgroup was assessed for changes from baseline in American Urological Symptom Index (AUA SI) score, quality of life (QoL) score, peak urinary flow rate (Q(max)), prostate volume, and postvoid residual urine volume (PVR) at 1, 2 and 3 years after PVP. RESULTS: All tPSA subgroups had a sustained improvement in all efficacy outcomes maintained through the 3 years. There was a statistically significant difference in the level of improvement between groups 1 and 2 (P < 0.05) in AUA SI and Q(max) at 1, 2 and 3 years. The mean (sd) prostate volume for group 1 was 48.3 (16.7) mL (87 men), and was 83.1 (30.6) mL (52 men) in group 2. The mean percentage improvement in the AUA SI at 1, 2 and 3 years in group 1 and 2, respectively, was 86%, 92% and 85%, and 69%, 74% and 76%; the corresponding percentage improvement in Q(max) was 194%, 185% and 179%, and 124%, 145% and 139%, respectively. Overall treatment efficacy in all patients evaluated showed a mean 83%, 79%, 71% and 165% improvement in AUA SI, QoL, PVR and Q(max), respectively. Adverse events were minimal and the re-treatment rate was 4.3%. CONCLUSIONS: These results suggest that there is a significant difference in efficacy in patients with a tPSA of < or = 6.0 ng/mL or > or = 6.1 ng/mL before PVP. However, the overall results achieved with PVP were very positive and durable to 3 years, irrespective of tPSA level and prostate volume.

The diagnosis and treatment of osteoporosis in men on androgen deprivation therapy for advanced carcinoma of the prostate.

PURPOSE: Androgen deprivation therapy (ADT) for advanced prostate cancer increases the risk of osteoporosis. Thus, the practicing urologist should be aware of the appropriate assessment and management. In this article we review the tests designed to diagnose osteoporosis as well as treatment options. We also review methods to monitor the response to therapy and make recommendations for management. MATERIALS AND METHODS: We performed a MEDLINE (1966 to 2004) search for the terms male, osteoporosis, bone mineral density, prostate cancer, androgen deprivation therapy, bisphosphonates, estrogen and the combinations thereof. We then constructed a management algorithm based on the best evidence available. RESULTS: Dual energy x-ray absorptiometry of the hip is the gold standard test for osteoporosis. Biochemical markers of bone turnover are not suitable for diagnosis but they have been shown to be useful for monitoring the response to treatment. Smoking cessation, weight bearing exercise, and vitamin D and calcium have been shown to help improve bone mineral density (BMD). Bisphosphonates have been demonstrated to increase BMD and decrease fracture risk in men with osteoporosis. Estrogens have also recently been shown to decrease bone turnover and increase BMD in men on ADT. CONCLUSIONS: Hip dual energy x-ray absorptiometry should be performed in all men who are anticipated to be on long-term ADT. In addition, all men on ADT should receive vitamin D and calcium supplementation, and perform regular weight bearing exercise. The value of smoking cessation cannot be overstated. In men who have osteopenia or osteoporosis bisphosphonate therapy should be initiated. Estrogen therapy has shown promise but specific recommendations cannot be made at this time.

Photoselective vaporization of the prostate for the treatment of benign prostatic hyperplasia: 12-month results from the first United States multicenter prospective trial.

PURPOSE: We report the 1-year efficacy and safety of photoselective vaporization of the prostate (PVP) for symptomatic and obstructive benign prostatic hyperplasia (BPH). MATERIALS AND METHODS: A prospective clinical trial was performed in 139 men clinically diagnosed with symptomatic bladder outlet obstruction secondary to BPH who were enrolled and treated with a high power, 80 W, quasicontinuous wave potassium-titanyl-phosphate laser at 6 American medical centers across the country. Efficacy parameters were mean and percent changes from baseline in the American Urological Association Symptom Index (AUA-SI) score, quality of life score (QOL), peak urinary flow rate (Qmax), post-void residual urine volume (PVR) and transrectal ultrasound prostate volume measurement. Patients were evaluated 1, 3, 6 and 12 months following treatment. At each followup evaluation side effects were elicited. RESULTS: Significant improvements in AUA-SI score, QOL score, Qmax and PVR were noted as early as 1 month after PVP treatment. At 12 months the mean AUA-SI score decreased from 23.9 to 4.3 (p <0.0001) and the QOL score decreased from 4.3 to 1.1 (p <0.0001), while mean Qmax increased from 7.8 to 22.6 ml per second (p <0.0001). PVR decreased from 114.3 to 24.8 ml (p <0.0001), while the transrectal ultrasound volume reduction went from 54.6 ml at baseline to 34.4 ml. There was no significant blood loss or fluid absorption during or immediately after PVP. Complications consisted of transient hematuria, dysuria and urinary retention in 12 (8.6%), 13 (9.3%) and 7 (5%) patients, respectively. CONCLUSIONS: PVP is a unique, safe and effective outpatient modality that provides immediate symptomatic and urodynamic relief of bladder outlet obstruction secondary to BPH. Long-term followup is needed to validate further the maintenance of clinical efficacy beyond 1 year.
