Optimizing Time to Treatment to Achieve Durable Biochemical Disease Control after Surgery in Prostate Cancer: A Multi-Institutional Cohort Study. Cancer Epidemiol Biomarkers Prev 2018; 28:570-577. [PMID: 30413401 DOI: 10.1158/1055-9965.epi-18-0812] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/20/2018] [Revised: 10/09/2018] [Accepted: 11/05/2018] [Indexed: 11/16/2022] Open
Abstract
BACKGROUND The impact of treatment delays on prostate cancer-specific outcomes remains ill-defined. This study investigates the effect of time to treatment on biochemical disease control after prostatectomy. METHODS This retrospective study includes 1,807 patients who received a prostatectomy as a primary treatment at two large tertiary referral centers from 1987 to 2015. Multivariate cox model with restricted cubic spline was used to identify optimal time to receive treatment and estimate the risk of biochemical recurrence. RESULTS Median follow-up time of the study was 46 (interquartile range, 18-86) months. Time to treatment was subcategorized based on multivariate cubic spline cox model. In multivariate spline model, adjusted for all the pertinent pretreatment variables, inflection point in the risk of biochemical recurrence was observed around 3 months, which further increased after 6 months. Based on spline model, time to treatment was then divided into 0 to 3 months (61.5%), >3 to 6 months (31.1%), and 6 months (7.4%). In the adjusted cox model, initial delays up to 6 months did not adversely affect the outcome; however, time to treatment >6 months had significantly higher risk of biochemical recurrence (HR, 1.84; 95% confidence interval, 1.30-2.60; P < 0.01). CONCLUSIONS The initial delays up to 6 months in prostate cancer primary treatment may be sustainable without adversely affecting the outcome. However, significant delays beyond 6 months can unfavorably affect biochemical disease control. IMPACT Time to treatment can aid clinicians in the decision-making of prostate cancer treatment recommendation and educate patients against unintentional treatment delays.

Abstract
BACKGROUND The perioperative period can be a critical period with long-term implications on cancer-related outcomes. In this study, we evaluate the influence of regional anesthesia on cancer-specific outcomes in a radical cystectomy (RC) cohort of patients. METHODS We performed a retrospective analysis of patients with clinically-nonmetastatic urothelial carcinoma of the bladder who underwent RC at our institution from 2008 to 2012. Patients were retrospectively registered and stratified based on two anesthetic techniques: perioperative epidural analgesia with general anesthesia (epidural) versus general anesthesia alone (GA). Epidural patients received a sufentanil-based regimen (median intraoperative sufentanil dose 50 mcg (45,85). Propensity-score was used to make 1:1 case-control matching. Cumulative risk of recurrence with competing risks was calculated based on anesthetic technique. Kaplan-Meier curves were used to compare recurrence-free (RFS) and cancer-specific survival (CSS). Univariable and multivariable analyses were performed with Cox proportional hazard regression models for RFS and CSS. RESULTS Only patients with complete data on anesthetic technique were included. Out of 439 patients, 215-pair samples with complete follow-up were included in the analysis. Median follow-up was 41.4 months (range: 0.20-101). Patients with epidurals received higher median total intravenous morphine equivalents (ivMEQ) versus those in the GA group (75 (11-235) vs. 50 ivMEQ (7-277), p < 0.0001). Cumulative risk of recurrence at two years was 25.2% (19.6, 31.2) for epidural patients vs. 20.0% (15.0, 25.7) for GA patients (Gray test p = 0.0508). Epidural analgesic technique was a significant predictor of worse RFS (adjusted HR = 1.67, 1.14-2.45; p = 0.009) and CSS (HR = 1.53, 1.04-2.25; p = 0.030) on multivariable analyses. CONCLUSIONS Epidural anesthesia using sufentanil was associated with worse recurrence and disease-free survival in bladder cancer patients treated with surgery. This may be due use of epidural sufentanil or due to the increased total morphine equivalents patient received as a consequence of this drug.

Abstract
Importance Neoadjuvant chemotherapy (NAC) followed by radical cystectomy improves survival compared with cystectomy alone for patients with bladder cancer. Although gemcitabine with cisplatin has become a standard NAC regimen, a dose-dense combination of methotrexate, vinblastine, doxorubicin, and cisplatin (ddMVAC) is being adopted at some institutions. Objective To assess the association of neoadjuvant ddMVAC vs standard regimens with downstaging and overall survival among patients treated with radical cystectomy for bladder cancer. Design, Setting, and Participants Cross-sectional analysis of data extracted from the medical records of a consecutive sample, after exclusions, of 1113 patients with bladder cancer of whom 824 had disease stage T2 or greater, who were treated with cystectomy at the Moffitt Cancer Center in Tampa, Florida, a tertiary care cancer center, between January 1, 2007, and May 31, 2017. Data were collected between November 14, 2016, and July 21, 2017, and analyzed between August 21, 2017, and December 8, 2017. Patients were compared based on type of NAC. Those who did not receive NAC were included as controls. Main Outcomes and Measures Comparative rates and the association of any downstaging, complete response, and overall survival with ddMVAC and other NAC regimens and surgery alone. Outcomes were examined using Kaplan-Meier, adjusted logistic, Cox regression, and propensity-weighted models. Results Of the 1113 patients who underwent cystectomy for bladder cancer, 861 (77.4%) were male, the median (interquartile range) age was 67 (60-74) years, 1051 (94.4%) were white, 27 (2.4%) black, 37 (3.3%) Hispanic/Latino, and 35 (3.1%) other race/ethnicity. Of 824 patients with muscle-invasive bladder cancer, 332 (40%) received NAC. Downstaging rates were 52.2% for ddMVAC, 41.3% for gemcitabine-cisplatin, and 27.0% for gemcitabine with carboplatin, and complete response (pT0N0) rates were 41.3% for ddMVAC, 24.5% for gemcitabine-cisplatin, and 9.4% for gemcitabine-carboplatin (2-sided P < .001). Adjusted analysis comparing ddMVAC with gemcitabine-cisplatin demonstrated a higher likelihood of downstaging (odds ratio [OR], 1.84; 95% CI, 1.10-3.09) and complete response (OR, 2.67; 95% CI, 1.50-4.77) with ddMVAC. Similar results were achieved with propensity score matching (OR, 1.52; 95% CI, 0.99-2.35). Patients who received ddMVAC had better overall survival than those treated with other chemotherapy regimens, although the observed survival benefit did not reach statistical significance in adjusted or propensity-matched models (hazard ratio, 0.44; 95% CI, 0.14-1.38; P = .16). Conclusions and Relevance This study suggest that neoadjuvant ddMVAC followed by cystectomy is associated with a higher complete response (ypT0N0) rate than standard NAC. These data highlight and suggest the need to further investigate ddMVAC vs standard NAC in a prospective, randomized fashion.

Abstract
OBJECTIVE To evaluate the mortality rates for prostate cancer according to geographical areas in Peru between 2005 and 2014. MATERIALS AND METHODS Information was extracted from the Deceased Registry of the Peruvian Ministry of Health. We analysed age-standardised mortality rates (world population) per 100 000 men. Spatial autocorrelation was determined according to the Moran Index. In addition, we used Cluster Map to explore relations between regions. RESULTS Mortality rates increased from 20.9 (2005-2009) to 24.1 (2010-2014) per 100 000 men, an increase of 15.2%. According to regions, during the period 2010-2014, the coast had the highest mortality rate (28.9 per 100 000), whilst the rainforest had the lowest (7.43 per 100 000). In addition, there was an increase in mortality in the coast and a decline in the rainforest over the period 2005-2014. The provinces with the highest mortality were Piura, Lambayeque, La Libertad, Callao, Lima, Ica, and Arequipa. Moreover, these provinces (except Arequipa) showed increasing trends during the years under study. The provinces with the lowest observed prostate cancer mortality rates were Loreto, Ucayali, and Madre de Dios. This study showed positive spatial autocorrelation (Moran's I: 0.30, P = 0.01). CONCLUSION Mortality rates from prostate cancer in Peru continue to increase. These rates are higher in the coastal region compared to those in the highlands or rainforest.

Abstract
Advanced bladder cancer patients have limited therapeutic options resulting in a median overall survival (OS) between 12 and 15 months. Adoptive cell therapy (ACT) using tumor infiltrating lymphocytes (TIL) has been used successfully in treating patients with metastatic melanoma, resulting in a median OS of 52 months. In this study, we investigated the feasibility of expanding TIL from the tumors of bladder cancer patients. Primary bladder tumors and lymph node (LN) metastases were collected. Tumor specimens were minced into fragments, placed in individual wells of a 24-well plate, and propagated in high dose IL-2 for four weeks. Expanded TIL were phenotyped by flow cytometry and anti-tumor reactivity was assessed after co-culture with autologous tumor digest and IFN-gamma ELISA. Of the 28 transitional cell bladder or LN tumors collected, 14/20 (70%) primary tumors and all of the LN metastases demonstrated TIL expansion. Expanded TIL were predominantly CD3+ (median 63%, range 10-87%) with a median of 30% CD8 + T cells (range 5-70%). TIL secreted IFN-gamma in response to autologous tumor. Addition of agonisitic 4-1BB antibody improved TIL expansion from primary bladder tumors regardless of pre-treatment with chemotherapy. This study establishes the practical first step towards an autologous TIL therapy process for therapeutic testing in patients with bladder cancer.

Abstract
BACKGROUND Further biomarkers are warranted to improve prognostic stratification of penile squamous cell carcinoma (PSCC) patients undergoing inguinal lymph node dissection (ILND). OBJECTIVE To assess the prognostic value of pretreatment neutrophil-to-lymphocyte ratio (NLR) in PSCC patients undergoing ILND and to investigate its role in predicting pathologic node-positive (pN+) disease. DESIGN, SETTING, AND PARTICIPANTS In total, 84 consecutive patients undergoing ILND for PSCC at our institution between 1994 and 2014 were identified. Sixty-eight patients with a complete blood count and differential prior to surgery were included. Median follow-up was 35.5 mo. OUTCOMES MEASUREMENTS AND STATISTICAL ANALYSIS Cut-off point analysis of NLR was performed using the Contal and O'Quigley method. Estimates of overall survival (OS), cancer-specific survival, and recurrence-free survival stratified by NLR were provided by the Kaplan-Meier method. Cox regression models were performed to determine predictors of survival and recurrence. Logistic regression models were used to identify factors associated with pathologic node-positivity. RESULTS AND LIMITATIONS The cut-off point value was determined to be 3. Median OS was significantly shorter for patients with NLR ≥3 than those with NLR <3 (30 vs 158 mo, p<0.001). NLR ≥3 was an independent predictor of worse OS (hazard ratio=2.48; 95% confidence interval [CI]: 1.02-6.06, p=0.046). On univariable analysis, NLR ≥3 was associated with an increased risk of pN+ disease (odds ratio [OR]=3.75; 95% CI: 1.30-10.81, p=0.014). However, on multivariable analysis adjusted for primary tumor grade, lymphovascular invasion, clinical N stage, and neoadjuvant treatment receipt, the association between NLR and pN+ disease was no longer significant (OR=3.66; 95% CI: 0.82-16.42, p=0.091). The retrospective design and limited size of the study are acknowledged limitations. CONCLUSIONS Pretreatment NLR is an independent predictor of OS in PSCC patients undergoing ILND and highlights the association between systemic inflammation and survival. Our data suggests that a simple biomarker of inflammation can serve as a prognosticator in PSCC. PATIENT SUMMARY Penile cancer is a rare malignancy in North America and Europe. Therefore, there is a lack of prognostic parameters to help predict oncologic and survival outcomes. In this report, patients with an elevated neutrophil-to-lymphocyte ratio had an increased risk of mortality.

Abstract
INTRODUCTION Inguinal lymph node dissection is an integral part in the management of invasive penile tumors with intraoperative assessment often aiding decision-making during dissection. In this study, we evaluate the diagnostic value of intraoperative frozen section (FS) and analyze clinicopathologic factors that affect its accuracy. MATERIAL AND METHODS We, retrospectively, reviewed 84 patients with squamous cell carcinoma of the penis who underwent inguinal lymph node dissection at our institution. Intraoperative FS from the superficial inguinal nodes was available in 65 patients and compared with correspondent permanent sections (pathologic node staging [pN]). Sensitivity and specificity were calculated and factors associated with a false negative event were analyzed using logistic regression. RESULTS The total positive node rate was 60% (39/65). Of 39 pN+ cases, 10 (25.6%) had false-negative FS, whereas the remaining 29 were concordant intraoperatively. Sensitivity and specificity were 0.74 and 1, respectively. On univariable analysis, higher body mass index was associated with a false negative event although there was no association with age, receipt of neoadjuvant therapy, or clinical node stage. CONCLUSION Intraoperative FS is highly specific and moderately sensitive for the detection of positive superficial inguinal lymph nodes in penile cancer. Its use can help guide intraoperative surgical planning while limiting its reliance for patients with higher body mass index.

Abstract
Background Techniques in genitourinary oncologic surgery have evolved over the past several years, shifting from traditional open approaches toward minimally invasive routes by laparoscopy. Methods We reviewed the literature on laparoscopic surgery for genitourinary cancer, with emphasis on contemporary indications, complications, and oncologic outcome of laparoscopic surgery for urologic malignancies. Results All urologic oncology procedures have been performed laparoscopically. Laparoscopic radical nephrectomy is becoming the preferred approach for managing kidney cancer. The initial experience with nephroureterectomy is encouraging. Laparoscopic radical prostatectomy is rapidly becoming the standard in Europe and is the procedure of choice in many centers in the United States. Conclusions When following the open oncologic principles for the surgical treatment of malignancies, laparoscopy offers similar oncologic clinical outcomes, less morbidity, improved operative precision, and reduced convalescence time.

Abstract
BACKGROUND The surgical approach to management of testis cancer has been traditionally through an open incision, but in the last decade, several centers have reported their experience with laparoscopic retroperitoneal lymph node dissection (LRPLND). METHODS We reviewed the English literature, summarized the outcomes, and included our initial experience with the LRPLND procedure. RESULTS Improvements in operative time, complications, and morbidity have occurred as surgical experience has increased. The procedure is more challenging in postchemotherapy patients. Outcomes at our institute are comparable to reported series from other institutions, and LRPLND is our current procedure of choice for RPLND. CONCLUSIONS LRPLND has been shown to be a safe, effective, minimally invasive procedure in the management of testicular cancer patients who require surgery to address the retroperitoneal lymph nodes.

Abstract
PURPOSE To our knowledge it is unknown whether concomitant inguinal lymph node dissection at the time of penectomy improves outcomes in patients with penile cancer. We analyzed predictors of regional recurrence as well as disease specific survival based on time of inguinal lymph node dissection. We also determined an optimal time to perform inguinal lymph node dissection. MATERIALS AND METHODS We reviewed the records of 84 consecutive patients with available nodal pathology findings. Recurrence-free and disease specific survival was estimated using the Kaplan-Meier method. Optimal time to inguinal lymph node dissection was assessed by ROC curves and used for dichotomization. Cox proportional HRs were used to identify predictors of regional recurrence after inguinal lymph node dissection. RESULTS A total of 47 (56%) and 37 patients (44%) presented with cN0 and cN+ disease, respectively, during a median followup of 21 months. A cutoff point of 3 months to perform inguinal lymph node dissection was used to dichotomize the cohort into early vs delayed groups. Early dissection in 51 men demonstrated 5-year recurrence-free survival of 77% vs 37.8% in 33 who underwent delayed dissection. Positive node disease (HR 23.2, 95% CI 2.98-181.2) and early inguinal lymph node dissection (HR 0.48, 95% CI 0.21-0.98) were predictors of regional recurrence. Five-year disease specific survival was 64.1% and 39.5% in the early and late dissection groups, respectively. CONCLUSIONS Three months appears to be an optimal window for performing inguinal lymph node dissection. While prospective trials are needed to define the role of upfront groin dissection, our results may help delineate patterns of referral and timing of inguinal lymph node dissection in patients with penile cancer.

Does Implementing an Enhanced Recovery After Surgery Protocol Increase Hospital Charges? Comparisons From a Radical Cystectomy Program at a Specialty Cancer Center. Urology 2017; 105:108-112. [PMID: 28342928 DOI: 10.1016/j.urology.2017.03.023] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/22/2017] [Revised: 02/21/2017] [Accepted: 03/15/2017] [Indexed: 10/19/2022]
Abstract
OBJECTIVE To compare perioperative charges induced at the initial phase of a standardized enhanced recovery after surgery (ERAS) program from a tertiary referral center. METHODS A multidisciplinary ERAS protocol was implemented in our department on July 2015. During the subsequent year, all patients were treated according to this protocol (ERAS group). The patients were compared in terms of real in-hospital charges per surgical episode with a control group consisting of consecutive patients before the start of ERAS. Individual charges were analyzed per sample population and compared with the Wilcoxon rank-sum test or t test. Additionally, cost variances for each group were evaluated. RESULTS A total of 257 consecutive patients were evaluated of which the last 112 were ERAS patients. The median length of stay for each group was 6 days (P = .748). ERAS patients incurred higher medication charges ($1939 vs $1729, P = .036). Control patients incurred higher supplies ($861 vs $692), treatment ($90 vs $72), and miscellaneous charges ($537 vs $388) (all, P < .001). The median total charges per patient were $59,539 for the control group and $60,655 for the ERAS group (P = .175). ERAS adoption significantly reduced variance in billed charges (P < .001). CONCLUSION ERAS implementation did not significantly increase expenditure for cystectomy patients. ERAS showed decreased variance in charges likely due to standardization of care while eliciting savings in supplies, treatment, and miscellaneous costs.
