Improved Outcomes of Enhanced Recovery After Surgery (ERAS) Protocol for Radical Cystectomy with Addition of a Multidisciplinary Care Process in a US Comprehensive Cancer Care Center.

INTRODUCTION: Although enhanced recovery after surgery (ERAS) components include both anesthesia and surgical care processes, it is unclear whether a multidisciplinary approach to implementing ERAS care processes improves clinical outcomes. The addition of multidisciplinary care with anesthesiology-related components to an existing ERAS protocol for radical cystectomy at a US comprehensive cancer center provided an opportunity to compare short- and long-term outcomes. METHODS: We retrospectively compared the outcomes of 116 consecutive patients who underwent cystectomy after implementation of a multidisciplinary ERAS protocol with those of a historical control group of 143 consecutive patients who had been treated with a surgical ERAS protocol. Length of stay, return of bowel function, rate of blood transfusion, nausea, pain, and readmission rates were examined. RESULTS: Implementation of a multidisciplinary ERAS protocol was associated with better postsurgical symptom control, as indicated by lower rates of patient-reported nausea (P < .05). Multivariate Poisson regression analysis showed a decrease in estimated intraoperative transfusions (P ≤ .001) after adjusting for the effects of potential confounding variables. There were no statistically significant differences noted in length of stay, return of bowel function, 30- and 90-day complications, or readmissions. CONCLUSION: This is the first study to investigate the effects of adding anesthesia ERAS components to an existing surgical ERAS protocol for radical cystectomy. We found that with the addition of anesthesia-related interventions, there was a decrease in transfusions and nausea.

Neoadjuvant Chemotherapy in Elderly Patients With Bladder Cancer: Oncologic Outcomes From a Single Institution Experience.

INTRODUCTION: We conducted this study to determine if, in appropriately selected elderly patients receiving neoadjuvant chemotherapy (NAC), clinical outcomes including pathologic complete response/downstaging and overall survival were similar to a younger cohort. METHODS: Chart review was performed on patients receiving NAC for urothelial carcinoma of the bladder (UCB) from 2004 to 2013. A total of 116 patients were identified that underwent NAC from 2004 to 2013 for ≥ cT2N0M0 UCB. Patients were excluded who received 2 cycles or less of chemotherapy (N = 18; 11 patients in the younger cohort, 7 in the elderly group; P = .74). Data was analyzed, and Kaplan-Meir analysis curves were used for survival and recurrence. RESULTS: Forty-six elderly patients (age ≥ 70 years) (67% cisplatin-based regimen) were identified and compared with 70 (93% cisplatin-based regimen) younger patients. The estimated glomerular filtration rate, performance status, preoperative hemoglobin, and body mass index were significantly worse in elderly patients. Dose reduction and pathologic downstaging to non-muscle-invasive disease was not statistically different between older and younger patients Complete pathologic response in older patients (16%) and in the younger cohort (17%) were similar (P = .146). There was no significant difference in follow-up, recurrence, or in median overall survival between patient groups (28 months elderly vs. 35 months younger; P = .78). Age was not an independent predictor of pathologic downstaging, complete response, overall survival, or recurrence-free survival. CONCLUSIONS: NAC in elderly patients (≥ 70 years old) demonstrated equivalent toxicity and oncologic outcomes in our single-institution cohort. Although older patients had significantly poorer performance status and renal function, there were no differences in survival or response to NAC.

Clinical Significance of p53 and p16(ink4a) Status in a Contemporary North American Penile Carcinoma Cohort.

BACKGROUND: Because of the low incidence of penile carcinoma (PC), the value of p16(ink4a), p53, and human papilloma virus (HPV) infection status in clinical practice remains unclear. Herein, we report our experience with potential clinical utility of these markers in men with PC treated at our institution. PATIENTS AND METHODS: Tissue microarrays of 57 cases of invasive penile squamous cell carcinomas were immunohistochemically stained for p16 and p53. HPV in situ hybridization (ISH) for high-risk subtypes was also performed. Association between marker status, nodal disease, overall (OS) and cancer-specific survival (CSS) were assessed. RESULTS: p16 and HPV ISH were positive in 23 (40%) and 24 (42%) of the cohort, respectively. The proportion of warty, basaloid, or mixed warty basaloid tumor subtypes were significantly greater in the p16-positive patients (48% vs. 3%; P < .01). p53 expression was negative in 31 (54%) cases. Only in p16-negative patients, positive p53 status was associated with pN+ disease (odds ratio, 4.4 [95% confidence interval (CI), 1.04-18.6]). In Kaplan-Meier analysis, the unadjusted estimated OS was insignificantly longer in p16-positive patients (median OS, 75 vs. 27 months; P = .27) and median CSS was not reached (P = .16). In a multivariable Cox proportional hazard model, when controlling for pathological nodal status and adjuvant chemotherapy, p16 status was a significant predictor for improved CSS (hazard ratio, 0.36 [95% CI, 0.13-0.99]). The worst CSS was seen in pN+ patients with double negative p16 and p53 expression (8 vs. 34 months; P = .01). CONCLUSION: In this current cohort, p53 and p16 status showed clinical utility in predicting nodal disease as well as survival.

Surgical outcomes in the management of isolated nodal recurrences: a multicenter, international retrospective cohort.

PURPOSE: We report a multicenter international cohort representing what is to our knowledge the largest surgical experience with managing isolated retroperitoneal nodal recurrence of renal cell carcinoma, a unique subset of locoregional disease, yet to be described in detail. MATERIALS AND METHODS: Patients with isolated nodal recurrence of pTanyN+M0 disease after nephrectomy were identified by retrospective chart review at 3 independent institutions. Progression-free survival was estimated by the Kaplan-Meier method and used to compare survival outcomes between primary T(1-2)N(any)M0 and T3N(any)M0 tumors as well as clear cell and nonclear cell histology renal cell carcinoma. RESULTS: A total of 22 patients met study inclusion criteria. Median time to local postoperative recurrence was 31.5 months (IQR 12.9-43.3). After resection of isolated nodal recurrence 10 patients (46%) had a secondary recurrence at a median of 11.2 months (IQR 8.1-18.4), of whom 2 (9%) died of the disease. Overall median progression-free survival was 12.7 months, including 24.8 months for T(1-2)N(any)M0 tumors, 9.9 months for T3N(any)M0 tumors, and 13.4 and 17.6 months for clear and nonclear cell renal cell carcinoma, respectively. CONCLUSIONS: Surgical resection represents the best curative option for patients who present with isolated retroperitoneal lymph node recurrence of renal cell carcinoma. Durable postoperative progression-free survival is attainable in many patients regardless of histology or clinical TNM stage. In addition, our cohort showed a lower renal cell carcinoma related mortality rate than in previous series of local metastasis. As such, all patients free of precluding comorbidities should be considered candidates for complete surgical resection performed by an experienced genitourinary surgeon.
