Outcomes of renal salvage for penetrating renal trauma: a single institution experience.

INTRODUCTION: Conservative management of penetrating renal trauma is emerging, with data originating from centers with variable level of trauma care. This study reviews the outcomes of renal salvage after penetrating trauma at a level I trauma center. MATERIALS AND METHODS: An institutional review board approved trauma registry at Saint Louis University Hospital was retrospectively analyzed, for patients with penetrating renal trauma from 2009 to 2014. Patients were divided into nephrectomy group (NG) or non-nephrectomy group (non-NG), and compared. A multi-variable analysis was performed to determine predictors of nephrectomy, with cross validation to evaluate the performance of the multi-variable model. Data was analyzed using R version 3.3.2. A p value of < 0.05 was considered as significant. RESULTS: A total of 121 patients were identified with penetrating renal trauma. Gunshot injury was the leading cause of injury (87%). Eighteen (15%) patients required nephrectomy. The overall mean injury severity score (ISS). was 20. High grade (grade 4-5) renal injuries were noted in 41 patients (34%). Among these, 14 patients (34%) underwent a nephrectomy, while 27 patients (66%) were managed conservatively to salvage renal units. CT grade of renal injury was the only predictor of nephrectomy, on multi-variable analysis (OR 17.09 CI 2.75-105.99, p = 0.002). CT grade of injury and injury severity score were predictors of endoscopic intervention on a sub group analysis of non-NG. CONCLUSIONS: CT grade of injury predicts nephrectomy after penetrating renal trauma. Conservative management is a feasible option in penetrating renal trauma even with a higher grade of injury.

Prognostic value of tissue-based biomarker signature in clear cell renal cell carcinoma.

OBJECTIVE: To improve risk stratification for recurrence prognostication in patients with localised clear cell renal cell carcinoma (ccRCC). PATIENTS AND METHODS: In all, 367 patients with non-metastatic ccRCC were included. The cohort was divided into a training and validation set. Using tissue microarrays, immunostaining was performed for 24 biomarkers representative of key pathways in ccRCC. Using Least Absolute Shrinkage and Selection Operator (LASSO) Cox regression, we identified several markers that were used to construct a risk classifier for risk of disease recurrence. RESULTS: The median (interquartile range) follow-up was 63.5 (24.0-85.3) months. Five out of 24 markers were selected by LASSO Cox regression for the risk classifier: N-cadherin, E-cadherin, Ki67, cyclin D1 and phosphorylated eukaryotic initiation factor 4E binding protein-1 (p-4EBP1). Patients were classified as either low, intermediate or high risk of disease recurrence by tertiles of risk score. The 5-year recurrence-free survival (RFS) was 93.8%, 87.7% and 70% for patients with low-, intermediate- and high-risk scores, respectively (P < 0.001). Patients with a high marker score had worse RFS on multivariate analysis adjusted for age, gender, race and the Mayo Clinic Stage, Size, Grade, and Necrosis (SSIGN) score (hazard ratio 3.66, 95% confidence interval 1.58-8.49, P = 0.003 for high vs low marker score in the overall cohort). The five-marker classifier increased the concordance index of the clinical model in both the training and validation sets. CONCLUSION: We developed a five-marker-based prognostic tool that can effectively classify patients with ccRCC according to risk of disease recurrence after surgery. This tool, if prospectively validated, could provide individualised risk estimation for patients with ccRCC.

Multi-disciplinary surgical approach to the management of patients with renal cell carcinoma with venous tumor thrombus: 15 year experience and lessons learned.

BACKGROUND: The management of patients with renal cell carcinoma (RCC) with venous tumor thrombus (VTT) is challenging. We report our 15 year experience in the management of patients with RCC with VTT utilizing a multidisciplinary team approach, highlighting improved total and specifically Clavien III-V complication rates. METHODS: We reviewed the records of 146 consecutive patients who underwent radical nephrectomy with venous thrombectomy between 1998 and 2012. Data on patient history, staging, surgical techniques, morbidity, and survival were analyzed. Additionally, complication rates between two surgical eras, 1998-2006 and 2006-2012, were assessed. RESULTS: The study included 146 patients, 97 males (66 %), and a median age of 61 years (range, 24-83). Overall complications rate was 53 %, high grade complications (Clavien III -V) occurred in 10 % of patients. Most importantly, there was a lower incidence of overall and high grade complications (45 % and 8 %, respectively) in the last 6 years compared to the earlier surgeries included in the study (67 % and 13 % respectively) [p = .008 and .03, respectively). 30 day postoperative mortality was 2.7 %. 5 year overall survival (5Y- OS) and 5 year cancer specific survival (5Y- CSS) were 51 % and 40 %, respectively. Metastasis was the only independent predictor factor for CSS (HR 3.8, CI 1.9-7.6 and p < .001) and OS (HR 2.6, CI 1.5-4.7 and p = .001) in all patients. CONCLUSIONS: Our data suggest that patients with RCC and VTT can be treated safely utilizing a multidisciplinary team approach leading to a decrease in complication rates.

Systematic Review of Decision Aids for Newly Diagnosed Patients with Prostate Cancer Making Treatment Decisions.

PURPOSE: Despite established evidence for using patient decision aids, use with newly diagnosed patients with prostate cancer remains limited partly due to variability in aid characteristics. We systematically reviewed decision aids for newly diagnosed patients with prostate cancer. MATERIALS AND METHODS: Published peer reviewed journal articles, unpublished literature on the Internet and the Ottawa decision aids web repository were searched to identify decision aids designed for patients with prostate cancer facing treatment decisions. A total of 14 aids were included in study. Supplementary materials on aid development and published studies evaluating the aids were also included. We studied aids designed to help patients make specific choices among options and outcomes relevant to health status that were specific to prostate cancer treatment and in English only. Aids were reviewed for IPDAS (International Patient Decision Aid Standards) and additional standards deemed relevant to prostate cancer treatment decisions. They were also reviewed for novel criteria on the potential for implementation. Acceptable interrater reliability was achieved at Krippendorff α = 0.82. RESULTS: Eight of the 14 decision aids (57.1%) were developed in the United States, 6 (42.8%) were print based, 5 (35.7%) were web or print based and only 4 (28.5%) had been updated since 2013. Ten aids (71.4%) were targeted to prostate cancer stage. All discussed radiation and surgery, 10 (71.4%) discussed active surveillance and/or watchful waiting and 8 (57.1%) discussed hormonal therapy. Of the aids 64.2% presented balanced perspectives on treatment benefits and risks, and/or outcome probabilities associated with each option. Ten aids (71.4%) presented value clarification prompts for patients and steps to make treatment decisions. No aid was tested with physicians and only 4 (28.6%) were tested with patients. Nine aids (64.2%) provided details on data appraisal and 4 (28.6%) commented on the quality of evidence used. Seven of the 8 web or computer based aids (87.5%) provided patients with the opportunity to interact with the aid. All except 1 aid scored above the 9th grade reading level. No evidence on aid implementation in routine practice was available. CONCLUSIONS: As physicians look to adopt decision aids in practice, they may base the choice of aid on characteristics that correlate with patient socioeconomic and educational status, personal practice style and practice setting.

Histologic upgrading in patients eligible for active surveillance on saturation biopsy.

INTRODUCTION: We evaluated the risk of histologic upgrading and upstaging in patients who met strict active surveillance (AS) criteria on saturation biopsy and elected to undergo radical prostatectomy. MATERIALS AND METHODS: A retrospective review was conducted of 362 consecutive, individual patients who underwent transrectal ultrasound guided saturation biopsy (32 cores) between 2006 and 2013. Thirty-one patients (9%) were eligible for AS based on Hopkins criteria for very low risk (VLR): stage T1c, prostate-specific antigen (PSA) density ≤ 0.15 ng/mL2, Gleason ≤ 6, ≤ 2 cores and ≤ 50% core. Twenty patients (64%) elected radical prostatectomy, 2 (7%) elected radiation treatment and 9 (29%) elected AS (n = 9, 29%). Radical prostatectomy results were used to evaluate for upgrading and upstaging. RESULTS: Patient and saturation biopsy characteristics were similar amongst radical prostatectomy, radiation and AS patients. Mean age was 63 years (range 50-75) and 27 patients (87%) had a prior negative biopsy. Median time to prostatectomy was 3 months (range 1-46). Upgrading (Gleason ≥ 7) was identified in 40% (n = 8) of patients: Gleason 3+4 (n = 7) and Gleason 4+3 (n = 1). Upstaging (≥ T3) was not identified. Mean follow up was 47 months (range 11-99) for all patients. No patient developed biochemical recurrence or required salvage treatment. CONCLUSIONS: Despite increased prostate sampling, patients who met strict AS criteria on saturation biopsy were at high risk for Gleason upgrading, but fortunately at low risk for upstaging and biochemical recurrence. Patients contemplating AS based on saturation biopsy results should be counseled appropriately. MRI-TRUS fusion biopsy may be an alternative to saturation biopsy until proven otherwise.

Dysregulation of ß-catenin is an independent predictor of oncologic outcomes in patients with clear cell renal cell carcinoma.

PURPOSE: Epithelial-to-mesenchymal transition is thought to have a crucial role in cancer progression and metastatic egress. We evaluated the association of ß-catenin, an important mediator of epithelial-to-mesenchymal transition, with pathological parameters and oncologic outcomes in patients with clear cell renal cell carcinoma. MATERIALS AND METHODS: Immunohistochemical staining was performed for ß-catenin on tissue microarrays of patients with nonmetastatic clear cell renal cell carcinoma. Membranous and cytoplasmic expression patterns were assessed separately. ß-Catenin was considered dysregulated if membranous as well as cytoplasmic expression was abnormal. Groups were compared based on normal vs dysregulated ß-catenin. Survival probabilities were assessed by the Kaplan-Meier method. Cox proportional hazard models were used to identify predictors of oncologic outcomes. RESULTS: Included in the study were 406 patients with a median followup of 58 months. Of the patients 52 (12.8%) and 25 (6.2%) experienced recurrence and died of clear cell renal cell carcinoma, respectively. ß-Catenin was dysregulated in 70 patients (17.2%). Dysregulation was uniformly associated with adverse pathological features, including advanced T stage, larger tumor diameter, nodal positivity, higher Fuhrman grade, tumor thrombus, sarcomatoid features, necrosis and lymphovascular invasion (each p<0.001). Patients with dysregulated ß-catenin had inferior recurrence-free and cancer specific survival (each p<0.001). On multivariate analysis adjusting for tumor stage, nodal status and grade dysregulation was an independent predictor of recurrence-free and cancer specific survival (HR 2.2, 95% CI 1.2-3.9, p=0.008 and HR 2.4, 95% CI 1.1-5.6, p=0.044, respectively). CONCLUSIONS: Dysregulation of ß-catenin may be an important phenomenon in clear cell renal cell carcinoma carcinogenesis. These findings support further study of ß-catenin, and systematic assessment of ß-catenin and epithelial-to-mesenchymal transition in clear cell renal cell carcinoma.

Prospective analysis of Ki-67 as an independent predictor of oncologic outcomes in patients with high grade upper tract urothelial carcinoma.

PURPOSE: We determined the association of the proliferation marker Ki-67 with pathological parameters and oncologic outcomes in patients with high grade upper tract urothelial carcinoma. MATERIALS AND METHODS: Immunohistochemical staining for Ki-67 was done prospectively in 101 consecutive patients undergoing radical nephroureterectomy/ureterectomy for high grade upper tract urothelial carcinoma. Data were compared based on Ki-67 status (normal vs over expressed). Survival was assessed by the Kaplan-Meier method. Cox regression analysis was done to identify independent predictors of time dependent outcomes. RESULTS: Median patient age was 70.0 years and median followup was 22.0 months (range 1 to 77). Overall, 30.2% of the population experienced recurrence and 24.8% died of upper tract urothelial carcinoma. Organ confined disease (T2 or less and lymph node negative), lymphovascular invasion and sessile architecture were present in 56.3%, 33.3% and 20.8% of patients, respectively. Ki-67 was over expressed in 73.3% of patients and associated with adverse pathological features. Patients with over expressed Ki-67 had significantly worse recurrence-free survival (43.2 vs 69.0 months, p = 0.006) and cancer specific survival (48.9 vs 68.9 months, p = 0.031) than patients with normal Ki-67. Patients with nonmetastatic disease similarly had worse recurrence-free survival (40.7 vs 71.8 months, p = 0.003) and cancer specific survival (41 months vs not attained, p = 0.008) for over expressed vs normal Ki-67. After adjusting for the effects of organ vs nonorgan confined disease Ki-67 over expression was an independent predictor of recurrence-free survival in the total cohort (HR 4.3, p = 0.05) and in patients with nonmetastatic disease (HR 8.5, p = 0.038). CONCLUSIONS: Ki-67 over expression was associated with adverse pathological features in cases of upper tract urothelial carcinoma. It was also an independent predictor of recurrence-free survival in patients with high grade upper tract urothelial carcinoma.

Prospective comparison of molecular signatures in urothelial cancer of the bladder and the upper urinary tract--is there evidence for discordant biology?

PURPOSE: Upper tract urothelial carcinoma is rare and less well studied than bladder cancer. It remains questionable if findings in bladder cancer can safely be extrapolated to upper tract urothelial carcinoma. We prospectively evaluate molecular profiles of upper tract urothelial carcinoma and bladder cancer using a cell cycle biomarker panel. MATERIALS AND METHODS: Immunohistochemical staining for p21, p27, p53, cyclin E and Ki-67 was prospectively performed for 96 patients with upper tract urothelial carcinoma and 159 patients with bladder cancer with nonmetastatic high grade urothelial carcinoma treated with extirpative surgery. Data were compared between the groups according to pathological stage. Primary outcome was assessment of differences in marker expression. Secondary outcome was difference in survival according to marker status. RESULTS: During a median followup of 22.0 months 31.2% of patients with upper tract urothelial carcinoma and 28.3% of patients with bladder cancer had disease recurrence, and 20.8% and 27.7% died of upper tract urothelial carcinoma and bladder cancer, respectively. The number of altered markers was not significantly different between the study groups. Overall 34 patients (35.4%) with upper tract urothelial carcinoma and 62 (39.0%) with bladder cancer had an unfavorable marker score (more than 2 markers altered). There were no significant differences between upper tract urothelial carcinoma and bladder cancer in the alteration status of markers, the number of altered markers and biomarker score when substratified by pathological stage. There were no significant differences in survival outcomes between patients with upper tract urothelial carcinoma and those with bladder cancer according to the number of altered markers and biomarker score. CONCLUSIONS: Our results demonstrate the molecular similarity of upper tract urothelial carcinoma and bladder cancer in terms of cell cycle and proliferative tissue markers. These findings have important implications and support the further extrapolation of treatment paradigms established in bladder cancer to upper tract urothelial carcinoma.

Oncologic outcomes following surgical resection of renal cell carcinoma with inferior vena caval thrombus extending above the hepatic veins: a contemporary multicenter cohort.

PURPOSE: Suprahepatic inferior vena caval tumor thrombus in renal cell carcinoma cases has historically portended a poor prognosis. With advances in perioperative treatment of patients with high level thrombus contemporary outcomes are hypothesized to be improved. We evaluated long-term oncologic outcomes of contemporary surgical treatment of patients with renal cell carcinoma in whom level III-IV inferior vena caval thrombus was managed at high volume centers. MATERIALS AND METHODS: We examined clinical and pathological data on patients with renal cell carcinoma and level III-IV thrombus treated with surgery from January 2000 to June 2013 at 4 tertiary referral centers. Survival outcomes and associated prognostic variables were assessed by Kaplan-Meier and multivariate Cox regression analyses. RESULTS: We identified 166 patients, including 69 with level III and 97 with level IV thrombus. Median postoperative followup was 27.8 months. Patients with no evidence of nodal or distant metastasis (pN0/X, M0) had 5-year 49.0% cancer specific survival and 42.2% overall survival. There was no difference in survival based on tumor thrombus level or pathological tumor stage. Variables associated with an increased risk of death from kidney cancer on multivariate analysis were regional nodal metastases (HR 3.94, p <0.0001), systemic metastases (HR 2.39, p = 0.01), tumor grade 4 (HR 2.25, p = 0.02), histological tissue necrosis (HR 3.11, p = 0.004) and increased preoperative serum alkaline phosphatase (HR 2.30, p = 0.006). CONCLUSIONS: Contemporary surgical management achieves almost 50% 5-year survival in patients without metastasis who have renal cell carcinoma thrombus above the hepatic veins. Factors associated with increased mortality included nodal/distant metastases, advanced grade, histological necrosis and increased preoperative serum alkaline phosphatase. These findings support an aggressive surgical approach to the treatment of patients with renal cell carcinoma who have advanced tumor thrombus.

Ki67 is an independent predictor of oncological outcomes in patients with localized clear-cell renal cell carcinoma.

OBJECTIVE: To validate the impact of Ki67 expression on oncological outcomes of patients treated for clinically localized clear-cell renal cell carcinoma (ccRCC). PATIENTS AND METHODS: Immunohistochemistry for Ki67 was performed on tissue microarray constructs of patients treated with radical or partial nephrectomy for clinically localized (M0) ccRCC and Ki67 expression >10% was considered abnormal. Clinical and pathological data elements were entered into an institutional review board-approved database. The Kaplan-Meier method and Cox regression models were used to analyse disease-free survival (DFS) and cancer-specific survival (CSS) probabilities. RESULTS: Of 401 patients, 59.6% were males. The median (range) age was 58 (17-85) years, follow-up was 22 (0-150) months and time to death was 27 (0-150) months. A total of 20.2% of patients had advanced stage (pT3-T4) and 31% had advanced grade (3-4) disease. Abnormal expression of Ki67 was seen in 6.5% of our cohort and was associated with adverse pathological features (P < 0.05). Patients with high expression of Ki67 were found to have 5-year DFS and CSS rates of 67 and 84%, respectively, vs 87 and 95%, respectively, in those with normal expression (P < 0.001 and P < 0.05, respectively). In multivariable analyses, adjusting for stage and grade, abnormal Ki67 expression was an independent predictor of DFS (hazard ratio [HR] 3.77, P = 0.011, 95% confidence interval [CI] 1.35-10.52), but not of CSS (HR 3.51 P = 0.137, 95% CI 0.671-18.35). CONCLUSIONS: Our findings support the role of Ki67 as a powerful independent predictor of inferior oncological outcomes in patients with ccRCC. Further prospective studies are needed to determine the clinical applicability of these findings.

Prognostic role of cell cycle and proliferative biomarkers in patients with clear cell renal cell carcinoma.

PURPOSE: Cell cycle regulatory molecules are implicated in various stages of carcinogenesis. In this proof of principle study we systematically evaluate the association of aberrant expression of cell cycle regulators and proliferative markers and their effect on oncologic outcomes of patients with clear cell renal carcinoma. MATERIALS AND METHODS: Immunohistochemistry for Cyclin D, Cyclin E, p16, p21, p27, p53, p57 and Ki67 was performed on tissue microarray constructs of 452 patients treated with extirpative therapy for clear cell renal cell carcinoma between 1997 and 2010. Clinical and pathological data elements were collected. A prognostic marker score was defined as unfavorable if more than 4 biomarkers were altered. The relationship between marker score and pathological features and oncologic outcomes was evaluated. RESULTS: Median age was 57 years (range 17 to 85) and median followup was 24 months (range 6 to 150). An unfavorable marker score was found in 55 (12.2%) patients and was associated with adverse pathological features. A significant correlation between unfavorable marker score and disease-free survival (HR 26.62, 95% CI 43.38-100.04, p=0.000) and with cancer specific survival (HR 8.15, 95% CI 74.42-101.56, p=0.004) was demonstrated on Kaplan-Meier survival analysis. On multivariate analysis an unfavorable marker score was an independent predictor of disease-free survival (HR 2.63, 95% CI 1.08-6.38, p=0.033). CONCLUSIONS: The cumulative number of aberrantly expressed cell cycle and proliferative biomarkers correlates with aggressive pathological features and inferior oncologic outcomes in patients with clear cell renal cell carcinoma. Our findings indicate that interrogation of cell cycle and proliferative markers is feasible, and further prospective pathway based exploration of biomarkers is needed.

Risk prediction in the management of small renal masses.

PURPOSE OF REVIEW: Small renal masses (SRMs) are frequently encountered due to the ubiquitous use of abdominal cross-sectional imaging. Enhanced risk prediction in the management of SRMs would allow for a more informed decision of which, if any, patients would benefit from the available intervention modalities. RECENT FINDINGS: Data suggest that a substantial proportion of SRMs are benign and that a significant proportion demonstrate indolent clinical behavior, leading to increased implementation of active surveillance strategies. Extirpative treatment of SRMs may be associated with worse outcomes, particularly in the elderly and infirm. Patient characteristics, including advanced age and comorbidity, and tumor anatomy are being increasingly recognized as having significant prognostic importance in terms of which type of treatment to offer. Further, a recent renewed interest in renal mass biopsy for risk stratification in SRMs has occurred as tumor size, radiographic characteristics, and growth kinetics are limited in their predictive capacity. SUMMARY: Within the last decade, the reference standard treatment of SRMs evolved from radical nephrectomy to nephron-sparing approaches. This evolution continues, as we learn more about the complex interplay between patient and tumor characteristics and, as outcomes data mature, to ablative therapies and active surveillance.

Neuraxial vs General Anesthesia: 30-Day Mortality Outcomes Following Transurethral Resection of Prostate.

OBJECTIVE: To examine the occurrence of 30-day mortality, and other procedure related morbidities in cohorts of patient receiving neuraxial anesthesia (NAX) or general anesthesia (GA) in the setting of transurethral resection of the prostate (TURP). Historically, NAX has been recommended for patients undergoing TURP permitting monitoring of consciousness and early diagnosis of absorption-related hyponatremia. We aim to analyze a broader comparison of mortality and other associated morbidities regarding the form of anesthesia utilized. METHODS: The National Surgical Quality Improvement Program (NSQIP) database was accessed and queried from January 2010 to December 2016 for TURP. 28,486 TURP cases were identified and further stratified by the type anesthesia administration, NAX 7,261 and GA 21,225. Chi-square analyses and Kaplan-Meier tests were performed for univariate comparisons. Using propensity score, data were optimally (1:1) matched to account for potential confounding variables. Outcomes were then compared for NAX vs. GA with a primary endpoint of 30-day mortality, followed by secondary endpoint of adverse outcomes reported per NSQIP. RESULTS: Prior to matching, 30-day mortality was found to be 0.4% in the NAX cohort and 0.7% GA. 12,180 patients equally matched between the 2 groups. NAX was found to be superior to GA in terms of 30-day survival benefit (OR 0.55, 95% CI 0.33 -0.92, P <0.05), sepsis (OR 0.60, 95% CI 0.50 -0.73, P <0.001), and return to operating room (OR 0.76, 95% CI 0.60 -0.98, P <0.05) when comparing matched cohorts. NAX was associated with lower incidence of overall adverse clinical outcomes 12.4% vs 13.7% (P = 0.036). CONCLUSION: NAX was found to have statistically relevant advantage for 30-day postoperative outcomes when compared to GA for TURP based on NSQIP database reporting.

Perioperative Hypothermia after Transurethral Surgeries: Is it Necessary to Heat the Irrigation Fluids?

OBJECTIVE: To investigate the role of heated irrigation fluids in the risk of hypothermia and related complications in patients undergoing transurethral procedures. METHODS: The medical records of all patients who underwent transurethral procedures between 2000 and 2016 at the VA Hospital were reviewed. Irrigation fluids have been heated to 42°C since 2013, as per the institutional policy (Group II). Prior to this date, room temperature solutions were used (Group I). The perioperative body temperature, use of warming devices, procedure length, and anaesthesia type were extracted from records and compared for both groups. In addition, demographic and anthropometric data, preoperative comorbidities, laboratory data, admission information and postoperative complications were obtained from the quality improvement database. RESULTS: There were 1,363 patients in Group I and 269 patients in Group II. Perioperative temperature was decreased by 0.10°C in Group I compared to a temperature gain of 0.32°C in Group II (p<0.001). Three hundred and forty-eight (21%) patients undergoing transurethral procedures developed hypothermia <36°C. There was no difference in the incidence of postoperative mortality or complications between the normothermic and hypothermic patients. CONCLUSION: The replacement of room temperature solutions with warmed solutions for irrigation during transurethral procedures reduced the risk of temperature loss and hypothermia following these procedures. Available heating strategies effectively prevented the perioperative heat loss; however, such strategies did not affect the incidence of postoperative complications.

Renal Oncocytoma and Retroperitoneal Ancient Schwannoma: A Benign Mimic of Metastatic Renal Cell Carcinoma.

Renal oncocytomas and retroperitoneal schwannomas are rare and typically benign tumors with characteristic histopathologic features. Ideal management of both renal oncocytoma and retroperitoneal schwannoma is surgical resection. We present a rare case of a 63-year-old man with multifocal renal oncocytoma and retroperitoneal ancient schwannoma which, preoperatively, masqueraded as metastatic renal cell carcinoma. Both tumors were successfully resected surgically. Immunochemistry and histopathology confirmed each diagnosis.

Prostate Cancer Survivors: Physical, Emotional and Practical Concerns from the LIVESTRONG Survey.

OBJECTIVE: To determine whether a relationship exists between types of treatment received and/or survivorship status of prostate cancer survivors with physical, emotional, and practical concerns that they experience with the hypothesis that no such relationship exists. METHODS: We analyzed data from the 2010 LIVESTRONG survey for cancer survivors which queried their physical, emotional, and practical concerns. This previously tested survey was administered between June 20, 2010 and March 31, 2011 on the LIVESTRONG.org website. Survivorship status was categorized as reported by the respondents: currently on treatment; living with cancer as a chronic condition; finished treatment less than 1 year ago; 1-5 years ago and; more than 5 years ago. Four categories were established for the types of treatment received: surgery, radiation, hormonal, and combination therapies. One-way ANOVA's were conducted to detect differences between groups and descriptive statistics were reported. RESULTS: Of 2,307 respondents overall, only 281 males were included in this study based on self-reported primary diagnosis of prostate cancer and US residency status. The mean age of respondents was 60 years (SD = 8.54 years) and majority were white (90%). One-way ANOVA detected significant differences between the number of physical (p = 0.02), emotional (p = 0.04), and practical (p = 0.00) concerns for patients receiving different treatments. When compared across the survivorship trajectory, only number of practical concerns (p = 0.00) experienced by prostate cancer survivors were significantly different. CONCLUSIONS: Study findings highlight significant differences in number of concerns experienced by the patients based on their survivorship stage and the type of treatment received. Incorporating strategies to address the differences in physical, emotional, and practical concerns are essential to help physicians and clinical team members provide high quality post treatment survivorship care.

Successful Nonoperative Management of High-Grade Blunt Renal Injuries.

Current management of high-grade blunt renal trauma favors a nonoperative approach when possible. We performed a retrospective study of high grade blunt renal injuries at our level I trauma center to determine the indications and success of nonoperative management (NOM). 47 patients with blunt grade IV or V injuries were identified between October 2004 and December 2013. Immediate operative patients (IO) were compared to nonoperatively managed (NOM). Of the 47 patients, 3 (6.4%) were IO and 44 (95.6%) NOM. IO patients had a higher heart rate on admission, 133 versus 100 in NOM (P = 0.01). IO patients had a higher rate of injury to the renal vein or artery (100%) compared to NOM group (18%) (P = 0.01). NOM failed in 3 of 44 patients (6.8%). Two required nonemergent nephrectomy and one required emergent exploration resulting in nephrectomy. Six NOM patients had kidney-related complications (13.6%). The renal salvage rate for the entire cohort was 87.2% and 93.2% for NOM. Nonoperative management for hemodynamically stable patients with high-grade blunt renal trauma is safe with a low risk of complications. Management decisions should consider hemodynamic status and visualization of active renal bleeding as well as injury grade in determining operative management.

Sarcomatoid Renal Cell Carcinoma Metastasis to the Penis.

Secondary cancers of the penis are extremely uncommon with less than 300 cases reported in the past 100 years. These cancers are most frequently a result of an aggressive or poorly managed primary prostate or bladder cancer and rarely a metastasis from a primary kidney tumor. Currently, there is no published literature which describes the spread of sarcomatoid renal cell carcinoma (SRCC) to the penis. In this report, we present a 55-year-old-man who presented with a large right-sided SRCC which metastasized to the base of his penis within 1 month of symptom onset. We also discuss the possible route of metastasis based on primary tumor size and location within the retroperitoneum.

Multi-institutional analysis of renal function outcomes following radical nephroureterectomy and partial ureterectomy for upper tract urothelial carcinoma.

PURPOSE: To compare renal function outcomes in patients undergoing radical nephroureterectomy (RNU) or partial (distal) ureterectomy (PU) for upper tract urothelial carcinoma (UTUC). METHODS: Clinicopathologic data of patients undergoing RNU or PU for UTUC from 1998 to 2012 were compiled. Glomerular filtration rate was calculated preoperatively and postoperatively using the Modification of Diet in Renal Disease equation. We defined "event" as new-onset stage III chronic kidney disease (CKD) or worsening of CKD stage with preexisting CKD. Event-free survival was assessed with Kaplan-Meier methods. Cox regression analyses were performed to identify predictors of events. RESULTS: In total, 193 patients underwent RNU (n = 143) or PU (n = 50) over a median follow-up of 25.9 months. Overall, 15% of patients died of UTUC. High tumor grade (85.9% vs. 66.0%, P = 0.003) and locally advanced stage (>pT2, 37.8% vs. 18.0%, P = 0.014) were significantly more frequent in the RNU cohort. Stage III or higher CKD was present in 61% of RNU patients vs. 48% of PU patients (P = 0.135) at baseline. Although total event rate was higher in the PU cohort (66% vs. 43.4%, P = 0.008), event rates within the first 3 months of surgery were similar between the groups (P = 0.572). Adjuvant chemotherapy was the only predictor of events on Cox regression. CONCLUSIONS: Rates of new-onset CKD or worsening of CKD stage were similar in patients treated with RNU and PU. Adjuvant chemotherapy may have a more significant effect on renal outcomes than surgical approach, warranting further investigation. Consideration should be given to preoperative chemotherapy, as adjuvant chemotherapy is limited by decreased renal function following surgery.

Lymphovascular invasion in clear cell renal cell carcinoma--association with disease-free and cancer-specific survival.

OBJECTIVES: The objective is to evaluate the effect of lymphovascular invasion (LVI) on disease-free survival (DFS) and cancer-specific survival (CSS) in patients with clinically localized clear cell renal cell carcinoma (ccRCC). METHODS: Patients with ccRCC who were treated surgically in 1997 to 2010 were identified. Retrospective chart review was performed to identify clinical outcomes. Independent pathologic re-review was performed by a single pathologist to confirm LVI status. Pathologic features were correlated with clinical outcomes using Kaplan-Meier and Cox regression analyses. RESULTS: Four hundred and nineteen patients with nonmetastatic ccRCC comprised the study cohort. Three hundred and thirty-three of these patients had an organ-confined (pT1-2, N any, and M0) disease. LVI was present in 14.3% of all nonmetastatic patients. In all patients with nonmetastatic ccRCC, presence of LVI was correlated with significantly shorter DFS (P <0.001) and CSS (P = 0.001) on Kaplan-Meier analysis. In cases of organ-confined, nonmetastatic ccRCC, presence of LVI was a significant predictor of DFS (hazard ratio = 4.0, P = 0.026) and CSS (hazard ratio = 12.7, P = 0.01) on multivariate analysis. Patients with organ-confined RCC who were LVI positive had similar DFS (P = 0.957) and CSS (P = 0.799) to patients with locally advanced tumors (pT3-pT4, N any, and M0) on Kaplan-Meier analysis. CONCLUSIONS: The presence of LVI is an independent predictor of both DFS and CSS in organ-confined, nonmetastatic ccRCC. LVI positivity in patients with otherwise pathologically organ-confined ccRCC confers oncologic outcomes similar to those of patients with locally advanced disease. If confirmed by others, future revisions to the tumor-node-metastasis staging system may incorporate LVI status into the prognostic algorithm of patients with RCC.
