ABSTRACT

OBJECTIVES: We postulated that an opiate-free (OF) general anesthesia (GA) technique could adequately control a patient's pain without adversely affecting recovery. We compared patients undergoing major urologic procedures with and without opiate-based GA. METHODS: A propensity-matched analysis was performed comparing hospital length of stay, postoperative nausea and vomiting, ileus occurrence, postanesthesia care unit, and total opiate consumption, as well as sedation and hemodynamic variables. The data are expressed as medians and were analyzed with the Wilcoxon rank-sum test. P < 0.05 indicate statistical significance. RESULTS: In total, 166 patients were evaluated in both the OF group and the opiate-based treatment group. American Society of Anesthesiologists classification and age were comparable, with most surgeries being laparoscopic and confined to the bladder, kidney, and prostate gland. The median opiate consumption in morphine equivalents in the postanesthesia care unit was 7.7 mg (range 5-11.7 mg) for the OF cohort versus 11.7 mg (range 5-17.3 mg) for the control group (P < 0.001). Similarly, the median total postoperative opiate consumption in morphine equivalents was 23.9 mg (range 13.8-42.4 mg) for the OF group compared with 32.1 mg (range 17.38-57.51 mg) for the control group (P = 0.0081). The median hospital length of stay for the OF group was 1.4 days (range 1.2-2.3 days) versus 1.3 days (range 1.2-2.4 days) for the control group (P = 0.8466). CONCLUSIONS: There was a statistically significant difference in opiate consumption postoperatively for patients who underwent an OF technique compared with a conventional opiate-based technique. This technique appears to be a possible alternative approach, without any apparent untoward consequences during admission.

ABSTRACT

BACKGROUND: Calls for multivisceral resection (MVR) of retroperitoneal sarcoma (RPS) are increasing, although the risks and benefits remain controversial. We sought to analyze current 30-day morbidity and mortality rates, and trends in utilization of MVR in a national database. METHODS: Overall morbidity, severe morbidity, mortality rates, and temporal trends were analyzed utilizing the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP). RESULTS: From 2012 to 2015, a total of 564 patients underwent RPS resection with 233 patients (41%) undergoing MVR. The MVR group had a higher rate of preoperative weight loss and larger tumors overall. When comparing MVR to non-MVR, there was no significant difference in overall morbidity (22% vs 17%, P = .13), severe morbidity (11% vs 8%, P = .18), or mortality (<1% vs 2%, P = .25). On multivariate analysis, MVR was not associated with increased overall morbidity or severe morbidity. Mortality rates were too low for meaningful statistical analysis. Annual rates of MVR ranged from 37% to 46% with no significant change over time (P = .47). RESULTS: Short-term morbidity and mortality rates after MVR for RPS remain acceptable, but rates of MVR show little change over time in NSQIP hospitals. Concerns about increased morbidity and mortality should not be viewed as a contraindication to wider implementation of MVR for RPS.

ABSTRACT

The outcome of nephron-sparing surgical management of small renal masses is generally favorable, specifically in terms of long term renal function, overall survival, and oncologic outcomes. Given the overall prognosis and renal function preservation, transplantation of kidneys with small renal masses has increasingly been accepted as a donor option for renal transplantation. We present a case of an incidental renal mass on preoperative donor transplant evaluation and subsequent ex-vivo donor partial nephrectomy at the time of renal transplantation.

ABSTRACT

INTRODUCTION: There has been growing use of adrenalectomy as a potentially curative treatment option for patients with oligometastatic disease to the adrenal gland. We sought to compare the perioperative outcomes of patients undergoing isolated adrenalectomy in the setting of disseminated cancer using the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database. Furthermore, we examined the impact of performing surgical sub-specialty on outcomes. MATERIALS AND METHODS: Data from the ACS-NSQIP database was obtained for patients between 2011 and 2016 who underwent adrenalectomy. Patients were stratified by the presence or absence of disseminated cancer. Univariate and multivariate regression analyses were performed to test for an association between the presence or absence of disseminated cancer and perioperative outcomes. The relationship between performing specialist and outcomes was also compared. RESULTS: A total of 4,207 patients were identified, with 270 (6.4%) in the disseminated cancer group. There was no significant difference in perioperative outcomes between patients with disseminated cancer and without disseminated cancer. On multivariate analysis, neither the presence of disseminated cancer (p = 0.47) nor the surgical sub-specialty performing adrenalectomy (p = 0.52) were associated with an increased risk postoperative morbidity or mortality. Of note, there was a statistically significant increase in the number of adrenalectomies performed by urologists in the setting of disseminated cancer (19.3% versus 10.4%, p < 0.01). CONCLUSIONS: Patients undergoing adrenalectomy in the setting of disseminated cancer did not have significantly worse perioperative outcomes compared to patients undergoing adrenalectomy for other indications. The adverse perioperative event rate was similar whether the operation was performed by a urologist or a general surgeon.

ABSTRACT

INTRODUCTION: The use of an electrocautery device (monopolar loop) for patients undergoing transurethral resection of bladder tumors (TURBT) is standard of care. The aim of this study is to establish non-inferiority of complication rates for a bipolar energy device, the PK PlasmaButton (PK Button), when compared to the monopolar loop. MATERIALS AND METHODS: Seventy-eight subjects (41 monopolar loop and 37 PK Button), were enrolled in a single-center, prospective, randomized study with cystoscopically detected bladder tumors that were judged endoscopically resectable with only one trip into the operating room. Intra and postoperative data on complication rates, operative time, catheterization time and disease recurrence rates at 3 month follow up were collected. RESULTS: Overall complication rates after TURBT with the monopolar loop or PK Button were similar, (56% versus 38% respectively, p = 0.107), however there were more bladder perforations in the monopolar loop arm compared to the PK Button arm (12.2% versus 0%, respectively, p = 0.028). There was no difference in overall operative time (p = 0.170), catheterization time (p = 0.709) and disease recurrence (p = 0.199). CONCLUSION: The results of this study demonstrated no difference between the monopolar loop and PK Button in regard to overall complications; however, there was a higher rate of bladder perforation with monopolar TURBT. PK Button vaporization for bladder tumors represents a promising alternative to traditional monopolar TURBT without compromising short term (3 month) cancer recurrence rates.

ABSTRACT

BACKGROUND AND OBJECTIVES: Among patients with disseminated malignancy (DMa), bowel obstruction is common with high operative morbidity. Since preoperative risk stratification is critical, we sought to compare three standard risk indices, the American Society of Anesthesiology (ASA) classification, Charlson comorbidity index (CCI), and modified frailty index (mFI). METHODS: We identified 1928 DMa patients with bowel obstruction who underwent an abdominal operation from 2007 to 2012 American College of Surgeons National Surgical Quality Improvement Program. Multivariate analyses assessed predictors of prolonged length of stay (LOS), 30-day serious morbidity and mortality. Receiver operating characteristics' areas under the curves (AUCs) for risk indices scores and 30-day mortality were assessed. RESULTS: Serious morbidity and mortality rates were 20.4% and 14.8%. ASA and CCI did not predict serious morbidity or prolonged LOS, but were predictors of mortality. The mFI did not predict prolonged LOS, but did predict serious morbidity and mortality. Subgroup analyses showed similar results. There were no significant differences between ASA, CCI, and mFI AUCs for mortality. CONCLUSIONS: ASA, CCI, and mFI are limited in their ability to predict postoperative adverse events among DMa patients undergoing surgery for bowel obstruction. These data suggest that a more tailored preoperative risk stratification tool would improve treatment planning.

ABSTRACT

BACKGROUND: The modified frailty index (mFI) is an important method to risk-stratify surgical patients and has been validated for general surgery and selected surgical subspecialties. However, there are currently no data assessing the efficacy of the mFI to predict acute morbidity and mortality in patients undergoing surgery for retroperitoneal sarcoma. METHODS: Using the American College of Surgeons' National Surgical Quality Improvement Program from 2007 to 2012, we performed a retrospective analysis of patients with a diagnosis of primary malignant retroperitoneal neoplasm who underwent surgical resection. The mFI was calculated according to standard published methods. Univariate and multivariate statistical analyses including χ2 and logistic regression were used to identify predictors of 30-d overall morbidity, 30-d severe morbidity (Clavien III/IV), and 30-d mortality. RESULTS: We identified 846 patients with the diagnosis of primary malignant retroperitoneal neoplasm who underwent surgical resection. The distribution mFI scores was 0 (48.5%) or 1 (36.3%), with only 4.5% of patients presenting with a score ≥3. Rates of 30-d overall morbidity, serious morbidity, and mortality were 22.6%, 12.9%, and 1.2%, respectively. Only selected mFI scores were associated with serious morbidity and overall morbidity on multivariate analysis (P < 0.05), and mFI did not predict 30-d mortality (P > 0.05). CONCLUSIONS: Our data demonstrate that the majority of patients undergoing retroperitoneal sarcoma resections have few, if any, comorbidities. The mFI was a limited predictor of overall and serious complications and was not a significant predictor of mortality. Better discriminators of preoperative risk stratification may be needed for this patient population.

ABSTRACT

Diffuse large B-cell lymphomas (DLBCL) are the most common lymphomas worldwide. They also appear to be the most common primary retroperitoneal lymphomas, but this presentation is relatively uncommon in the literature. Retroperitoneal masses, including lymphomas, often present with nonspecific symptoms and laboratory values, necessitating radiographic assessment and consideration of mass biopsy prior to the initiation of treatment. Here we present a case of a primary retroperitoneal DLBCL as well as a review of the clinical presentation, imaging findings, and differential diagnosis of such tumors.

ABSTRACT

Screening recommendations for prostate cancer remain controversial, and no specific guidelines exist for screening in renal transplant candidates. To examine whether the use of prostate-specific antigen (PSA)-based screening in patients with ESRD affects time to transplantation and transplant outcomes, we retrospectively analyzed 3782 male patients ≥18 years of age undergoing primary renal transplant evaluation during a 10-year period. Patients were grouped by age per American Urological Association screening guidelines: group 1, patients <55 years; group 2, patients 55-69 years; and group 3, patients >69 years. A positive screening test result was defined as a PSA level >4 ng/ml. We used univariate analysis and Cox proportional hazards models to identify the independent effect of screening on transplant waiting times, patient survival, and graft survival. Screening was performed in 63.6% of candidates, and 1198 candidates (31.7%) received kidney transplants. PSA screening was not associated with improved patient survival after transplantation (P=0.24). However, it did increase the time to listing and transplantation for candidates in groups 1 and 2 who had a positive screening result (P<0.05). Furthermore, compared with candidates who were not screened, PSA-screened candidates had a reduced likelihood of receiving a transplant regardless of the screening outcome (P<0.001). These data strongly suggest that PSA screening for prostate cancer may be more harmful than protective in renal transplant candidates because it does not appear to confer a survival benefit to these candidates and may delay listing and decrease transplantation rates.

ABSTRACT

PURPOSE: Tailoring perioperative management to minimize the postoperative complication rates depends on reliable prognostication of patients most at risk. The Surgical Apgar Score is an objective measure of the operative course validated to predict major complications and death after general/vascular surgery. We assessed the ability of the Surgical Apgar Score to identify patients most at risk for postoperative morbidity and mortality after renal mass excision. MATERIALS AND METHODS: Data for 886 patients undergoing renal mass excision via radical or partial nephrectomy from 2010 to 2013 were extracted from a prospectively collected database. The Surgical Apgar Score was calculated using electronic anesthesia records. Major postoperative complications, readmission and reoperation within 30 days of surgery as well as 90-day mortality were examined. RESULTS: Overall 13.2% of patients experienced major postoperative complications at 30 days. Clavien grade I, II, III, IV and V complications were experienced by 1.7%, 2.9%, 5.8%, 1.9% and 0.9%, respectively. The 90-day all cause mortality rate was 1.4%. The Surgical Apgar Score was significantly lower in patients experiencing major complications (mean 7.3 vs 7.8, p=0.004) and death (6.3 vs 7.7, p=0.03). Patients with a Surgical Apgar Score of 4 or less were 3.7 times more likely to experience a major complication (p=0.01) and 24 times more likely to die within 90 days of surgery (p=0.0007) compared to patients with a Surgical Apgar Score greater than 8. CONCLUSIONS: The Surgical Apgar Score is an easily collected metric that can identify patients at higher risk for major complications and death after renal mass excision. A prospective trial to help further delineate the optimal use of this tool in an adjusted perioperative management approach with patients undergoing renal mass excision is warranted.

ABSTRACT

BACKGROUND: Frailty has gained recognition as an objective measure of a patient's physiologic reserve that ideally can replace the subjective biases of surgeons. In this study, we sought to examine the concordance between patient and attending surgeon perceptions of the patient's "fitness" before surgery. We then correlated these ratings with the patient's objective frailty scores. METHODS: Patients were prospectively enrolled from urology, general surgery, and surgical oncology clinics. Patients were asked to rate their ability to withstand the physical stress of the scheduled surgery on a visual analog scale. The operating surgeon then independently rated his assessment of the patient's ability to withstand surgery blinded to the patient's self assessment. RESULTS: A total of 203 patients were included. Median patient age and body mass index were 62 (range = 21-87) years and 28.1 kg/m(2) (18.0-53.1), respectively. The majority of patients were white (67%) and male (60.6%). A patients' self-assessment showed no correlation with their age; however, surgeons' ratings showed a positive correlation with patients' age. Patients' self-rated scores showed a positive correlation with their frailty score, although surgeons' ratings showed a stronger correlation. However, when stratified by age group, the positive correlation and predictive ability were lost (P value = 0.198). CONCLUSIONS: Although age is an established risk factor, our data demonstrate surgeons may place an overreliance on a patient's age in place of an objective measure of physiologic reserve. Conversely, patients tended to overestimate their ability to withstand the stress of surgery, possibly leading to unrealistic expectations of their recovery and outcomes.

ABSTRACT

For patients with non-muscle invasive bladder cancer, cystoscopy and transurethral resection/vaporization of the bladder tumor plays an integral role in the treatment of a given patient's bladder cancer. Although considered the current gold standard for tumor detection, traditional or white light cystoscopy has been shown to have its limitations visualizing both small papillary tumors and/or carcinoma in-situ. Current efforts have been directed to closing this gap with data demonstrating that by identifying these previously missed lesions, tumor recurrence and progression rates are reduced, thereby improving patient outcomes. Narrow Band Imaging, which can be used during cystoscopy and transurethral resection/vaporization of bladder tumors, can aid in visualizing mucosal and sub-mucosal hypervascularity--a probable surrogate for malignant lesions--potentially visualizing the boundaries of lesions that may have been missed during white light cystoscopy alone. This technique may produce equivalent visual markers with fewer logistical hurdles than currently available methods. In this article, we detail our technique for the adjunctive use of Narrow Band Imaging during cystoscopy and transurethral resection/vaporization of bladder tumors to aid in visualizing mucosal and sub-mucosal hypervascularity. Although not yet readily adopted, Narrow Band Imaging may be a practical and easy to use adjunct to existing methods in visualizing occult bladder lesions.

ABSTRACT

INTRODUCTION: To compare radiation related toxicities among men with low risk prostate cancer treated with single or multimodal radiation therapy. MATERIALS AND METHODS: The SEER-Medicare linked database was used to assess the relationship between treatment type and toxicity among men with low risk prostate cancer treated with brachytherapy (BT), external beam radiation therapy (EBRT), or combined therapy between 2004 and 2007. Inverse probability of treatment weighting was utilized to minimize selection bias and control for confounding. Multivariate logistic regression models were used to explore the relationship between treatment and outcomes. RESULTS: Overall 1915 (43.9%), 1893 (43.4%), and 555 (12.7%) patients were treated with EBRT, BT, and combined therapy, respectively. In univariate analyses, combined modality radiation was more toxic than BT alone for GU incontinence (56.76% versus 49.08%), GU obstruction (21.26% versus 19.70%), and erectile dysfunction (22.52% versus 22.24%) (p < 0.01, all comparisons). Compared to EBRT alone, combined modality radiation was more toxic for GI bleeding (7.21% versus 6.21%), GU incontinence (56.76% versus 29.24%), GU obstruction (21.26% versus 14.15%), and erectile dysfunction (22.52% versus 15.35%) (p < 0.01, all comparisons). Among the most frequent radiation toxicity events, the probability of treatment associated toxicity was highest for patients receiving combined modality treatment and lowest for the group treated with EBRT. After multivariate adjustment, EBRT alone demonstrated protective effects against GU obstruction (OR 0.56 [CI 0.50-0.63]), GI bleeding (OR 0.57 [CI 0.48-0.67]), GU incontinence (OR 0.39 [CI 0.36-0.43]), and erectile dysfunction (OR 0.68 [CI 0.61-0.76]) when compared to combined therapy. CONCLUSIONS: The use of combined modality radiation therapy in low risk prostate cancer patients is discordant with clinical guidelines and associated with a significantly increased burden of associated toxicity when compared to EBRT monotherapy. Prudent patient selection and judicious use of combined therapy among men with low risk prostate cancer represents a targetable area to reduce the burden of overtreatment.

ABSTRACT

INTRODUCTION: Sarcomatoid urothelial carcinoma is a dedifferentiated biphasic tumor that exhibits morphological and/or immunohistochemical evidence of epithelial and mesenchymal differentiation. In this series, we analyzed the clinicopathologic features of this rare variant of urothelial carcinoma. MATERIALS AND METHODS: A search was made through our surgical pathology files and consultation files of the senior author for cases of sarcomatoid urothelial carcinoma of the bladder from 2005-2014. All the slides were retrieved and re-reviewed, and clinical data was also obtained including follow up. RESULTS: Thirty-seven cases of sarcomatoid urothelial carcinoma of the bladder were identified. Mean patient age was 71 years (range: 51 to 88 years). Twenty-six of 37 (70%) patients were male and 11/37 (30%) patients were female. Twenty-five cases were from cystectomy/cystoprostatectomy specimens, 8 cases from transurethral resection of bladder tumor specimens and 4 cases were from biopsy specimens. The mean tumor size was 5 cm (range: 1.4 cm to 13.0 cm). Four of 37 (10%) cases had focal heterologous components; 1 case with both chondroid and osteoid, 2 cases with chondroid and 1 case rhabdoid elements. Twenty-one of 37 (56%) patients died within a year of presentation. CONCLUSIONS: Sarcomatoid urothelial carcinoma of the bladder is more prevalent in males, with the mean age of 71 years in our series. Smoking is an important risk factor. Sarcomatoid urothelial carcinoma is an aggressive variant of urothelial carcinoma which commonly presents at an advanced stage, and over 50% of patients in our series died of disease within 1 year of presentation.

ABSTRACT

OBJECTIVES: To incorporate C-reactive protein into nomograms estimating survival in patients with renal cell carcinoma. METHODS: Patients undergoing surgery for renal cell carcinoma from 2005-2012 were studied retrospectively. Multivariable Cox proportional hazards regression and competing risks regression models including stage, grade, C-reactive protein levels and presence of metastatic disease were constructed. Outcomes analyzed include overall mortality overall mortality and renal cell carcinoma-specific mortality. RESULTS: The cohort included 516 patients with a mean follow up of 1.7 years (SD 1.4 years). One- and 3-year renal cell carcinoma-specific mortality was 8.8% and 13.5%, respectively. Four nomograms were generated using overall mortality and renal cell carcinoma-specific mortality as end-points, two each for pre- and postoperative counseling. The factor with the largest effect on all nomograms was preoperative C-reactive protein. Based on the internal validation with bootstrapping, the concordance indices for renal cell carcinoma-specific mortality in the preoperative nomogram, postoperative nomogram, and the Mayo Clinic stage, size, grade and necrosis score were 0.889, 0.893, and 0.832, respectively (P = 0.005 and 0.002 comparing with stage, size, grade and necrosis scores for preoperative or postoperative nomograms). For overall mortality, the preoperative nomogram, postoperative nomogram, and stage, size, grade and necrosis score showed concordance indices of 0.866, 0.897, and 0.828, respectively (P = 0.123 and 0.008 compared with stage, size, grade and necrosis score for preoperative or postoperative nomograms). CONCLUSIONS: We have generated nomograms incorporating serum C-reactive protein levels that effectively predict overall mortality and renal cell carcinoma specific mortality. Our findings warrant external validation.

ABSTRACT

PURPOSE: Compared to T1a lesions the natural history of untreated renal masses larger than 4 cm is poorly understood. We assessed the growth kinetics and outcomes of cT1b/T2 cortical renal tumors managed by an initial period of active surveillance. We compared these cases to those treated with definitive delayed intervention. MATERIALS AND METHODS: We reviewed our institutional, prospectively maintained renal tumor database to identify enhancing solid and cystic masses managed expectantly. Included in analysis were clinically localized tumors greater than 4.0 cm (T1b or greater) that were radiographically followed for more than 6 months. Tumor size at presentation, annual linear tumor growth rate, Charlson comorbidity index, followup and clinical outcomes were compared in patients who remained on active surveillance and those who underwent delayed surgical intervention. RESULTS: We identified 72 tumors 4 cm or greater in diameter in a total of 68 patients. Active surveillance was the only treatment in 45 patients (66%) while 23 (34%) progressed to intervention. Median tumor size at presentation was 4.9 cm and the mean linear growth rate was 0.44 cm per year. Of the masses 14.7% demonstrated no growth with time. Comparing patients treated exclusively with active surveillance and those who progressed to definitive intervention revealed no difference in median tumor size at presentation (4.9 vs 4.6 cm, p = 0.79) or the median Charlson comorbidity index (3 vs 2, p = 0.6) but significant differences were seen in median age at presentation (77 vs 60 years, p = 0.0002) and the mean linear growth rate (0.37 vs 0.73 cm per year, p = 0.02). After adjustment younger patients (OR 0.91, 95% CI 0.86-0.97) and tumors with a faster linear growth rate (OR 9.1, 95% CI 1.7-47.8) were more likely to be treated with delayed surgical intervention. At a mean ± SD 38.9 ± 24.0 months of followup (median 32, range 6 to 105) 9 patients (13%) had died of another cause and none had progressed to metastatic disease. CONCLUSIONS: Localized cT1b or larger renal masses show growth rates comparable to those of small tumors managed expectantly with a low rate of progression to metastatic disease at short-term followup. An initial period of active surveillance to determine tumor growth kinetics is a reasonable option in select patients with significant competing risks and limited life expectancy.

ABSTRACT

PURPOSE: The incidence of lower urinary tract symptoms (LUTS) as the sole presenting symptom for bladder cancer has traditionally been reported to be low. The objective of this study was to evaluate the prevalence and clinical characteristics of newly diagnosed bladder cancer patients who presented with LUTS in the absence of gross or microscopic hematuria. MATERIALS AND METHODS: We queried our database of bladder cancer patients at the Atlanta Veteran's Affairs Medical Center (AVAMC) to identify patients who presented solely with LUTS and were subsequently diagnosed with bladder cancer. Demographic, clinical, and pathologic variables were examined. RESULTS: 4.1% (14/340) of bladder cancer patients in our series presented solely with LUTS. Mean age and Charlson Co-morbidity Index of these patients was 66.4 years (range = 52-83) and 3 (range = 0-7), respectively. Of the 14 patients in our cohort presenting with LUTS, 9 (64.3%), 4 (28.6%), and 1 (7.1%) patients presented with clinical stage Ta, carcinoma in Situ (CIS), and T2 disease. At a median follow-up of 3.79 years, recurrence occurred in 7 (50.0%) patients with progression occurring in 1 (7.1%) patient. 11 (78.6%) patients were alive and currently disease free, and 3 (21.4%) patients had died, with only one (7.1%) death attributable to bladder cancer. CONCLUSIONS: Our database shows a 4.1% incidence of LUTS as the sole presenting symptom in patients with newly diagnosed bladder cancer. This study suggests that urologists should have a low threshold for evaluating patients with unexplained LUTS for underlying bladder cancer.

ABSTRACT

INTRODUCTION: High-grade T1 (HGT1) bladder cancer represents a clinical challenge in that the urologist must balance the risk of disease progression against the morbidity and potential mortality of early radical cystectomy and urinary diversion. Using two non-muscle invasive bladder cancer (NMIBC) databases, we re-examined the rate of progression of HG T1 bladder cancer in our bladder cancer populations. MATERIALS AND METHODS: We queried the NMIBC databases that have been established independently at the Atlanta Veterans Affairs Medical Center (AVAMC) and the University of Pennsylvania to identify patients initially diagnosed with HGT1 bladder cancer. Demographic, clinical, and pathologic variables were examined as well as rates of recurrence and progression. RESULTS: A total of 222 patients were identified; 198 (89.1%) and 199 (89.6%) of whom were male and non-African American, respectively. Mean patient age was 66.5 years. 191 (86.0%) of the patients presented with isolated HG T1 disease while 31 (14.0%) patients presented with HGT1 disease and CIS. Induction BCG was utilized in 175 (78.8%) patients. Recurrence occurred in 112 (50.5%) patients with progression occurring in only 19 (8.6%) patients. At a mean follow-up of 51 months, overall survival was 76.6%. Fifty two patients died, of whom only 13 (25%) patient deaths were bladder cancer related. CONCLUSIONS: In our large cohort of patients, we found that the risk of progression at approximately four years was only 8.6%. While limited by its retrospective nature, this study could potentially serve as a starting point in re-examining the treatment algorithm for patients with HG T1 bladder cancer.

ABSTRACT

PURPOSE: The modified Glasgow prognostic Score (mGPS) incorporates C-reactive protein and albumin as a clinically useful marker of tumor behavior. The ability of the mGPS to predict metastasis in localized renal cell carcinoma (RCC) remains unknown in an external validation cohort. PATIENTS AND METHODS: Patients with clinically localized clear cell RCC were followed for 1 year post-operatively. Metastases were identified radiologically. Patients were categorized by mGPS score as low-risk (mGPS = 0 points), intermediate-risk (mGPS = 1 point) and high-risk (mGPS = 2 points). Univariate, Kaplan-Meier and multivariate Cox regression analyses examined Recurrence -free survival (RFS) across patient and disease characteristics. RESULTS: Of the 129 patients in this study, 23.3% developed metastases. Of low, intermediate and high risk patients, 10.1%, 38.9% and 89.9% recurred during the study. After accounting for various patient and tumor characteristics in multivariate analysis including stage and grade, only mGPS was significantly associated with RFS. Compared with low-risk patients, intermediate- and high-risk patients experienced a 4-fold (hazard ratios [HR]: 4.035, 95% confidence interval [CI]: 1.312-12.415, P = 0.015) and 7-fold (HR: 7.012, 95% CI: 2.126-23.123 P < 0.001) risk of metastasis, respectively. CONCLUSIONS: mGPS is a robust predictor of metastasis following potentially curative nephrectomy for localized RCC. Clinicians may consider mGPS as an adjunct to identify high-risk patients for possible enrollment into clinical trials or for patient counseling.

ABSTRACT

PURPOSE: Patients with unilateral synchronous multifocal renal masses represent a unique population with renal cell carcinoma. While pathological concordance rates have been studied for bilateral cases, limited data exist on unilateral multifocal disease. We characterized pathological concordance rates in this population and evaluated the outcomes of nephron preservation. MATERIALS AND METHODS: Patients who underwent surgery from 2000 to 2012 for unilateral synchronous multifocal renal masses were identified from a prospectively maintained database. Demographic, surgical and pathological outcomes of this cohort were analyzed. Malignant concordance rates were defined as agreement of all malignant tumor types in a single renal unit. Histological concordance was defined as agreement of all resected mass histologies, eg all clear cell carcinomas. Nuclear grade was considered concordant if all tumors excised were low (Fuhrman 1 or 2, type 1) or high (Fuhrman 3 or 4, type 2) grade. RESULTS: Using our institutional database of 2,569 patients with renal tumors we identified 97 with unilateral synchronous multifocal renal masses. Malignant and benign concordance rates were 77.2% and 48.6%, and histological and grade concordance rates were 58.8% and 51.5%, respectively. In this cohort we identified 76 patients (76.3% male) with a median age of 62.5 years who had a total of 241 unilateral synchronous multifocal renal masses and underwent nephron sparing surgery. Median mass size was 2.0 cm (IQR 1.1-3.1), there was a median of 3 tumors per patient and median followup was 24 months (IQR 13-40). Identified renal cell carcinoma histologies included clear cell in 49.4% of cases, papillary in 33.5%, mixed in 4.5% and chromophobe in 2.8%. CONCLUSIONS: In what is to our knowledge the largest published report of unilateral synchronous multifocal renal masses we document low pathological concordance rates. As such, percutaneous biopsy of a single renal mass in these patients may not help inform treatment decisions. Nephron sparing surgery may be performed with acceptable oncological and functional results in patients with unilateral synchronous multifocal renal masses.
