Metastatic Melanoma to the Bladder: Case Report and Review of the Literature.

A 49-year-old Caucasian woman presented to the dermatology clinic for follow-up of malignant melanoma with a complaint of painless gross hematuria. Two years prior she was diagnosed with malignant melanoma from a skin lesion on her left flank treated with wide excision, negative axillary sentinel lymph node biopsy, and adjuvant radiotherapy. Subsequently, she had no evidence of disease until urologic evaluation of her hematuria revealed two lesions in her bladder and cytopathology demonstrated findings consistent with malignant melanoma. We review literature on melanoma metastatic to the bladder and discuss the potential role of metastasectomy and other treatment strategies in such rare cases

Імітація монаршної поведінки в “дивних” вчинках Богдана Хмельницького на початку 1649 р.

Увага до постаті Богдана Хмельницького як на фаховому, так і на дилетантському рівні не вщухає вже, навіть попри періодичні офіційні чи неофіційні заборони, протягом трьох з половиною століть. Політичні та ідеологічні чинники, як можна спостерігати останні півтора десятиліття в Україні та, частково, у Польщі, регулярно посилюють інтерес до біографії гетьмана, його вчинків, наслідків діяльності, супроводжуючись, як нерідко трапляється в аналогічних ситуаціях, створенням зі складної, протирічливой, трагічної постаті Б.Хмельницького національного ідола, усі дії якого набувають містичного, пророчого, апріорно історично-виправданого характреру. Концептуальні трагічні помилки, прорахунки, прояви некомпетентності, невиправданої навіть за поняттями тієї епохи жорстокості переважно «делікатно» замовчуються, у кращому разі – обмежуються легкими докорами, а здебільше - пояснюються «злочинною змовою» сучасників-поляків, які свідомо з метою дискредитації сфальсифікували вчинки гетьмана, перебільшивши закономірні для усіх війн трагічні складові україно-польської війни. Як не парадоксально, до сьогодні залишаються, на жаль, поодинокими спроби дати добре аргументоване, позбавлене соціологічних та психологічних штампів, пояснення тих чи інших вчинків Б.Хмельницького та його соратників (як, власне, і представників польського, татарського, російського та турецького таборів), яке б базувалося не на упередженому заздалегідь виправдальному чи звинувачувальному ставленні до подій середини XVII ст., а на підгрунті максимально повного врахування ментальних, поведінкових стереотипів доби. Ми маємо на увазі вишукано-резонансну рецензію Н.Яковенко на серію публікацій перш за все В.Смолія та В.Степанкова [17; див. також: 19], а також деяких інших авторів, зокрема О.Толочка [11] та автора цих рядків [2], присвячених політичній та духовній ситуації в Україні напередодні Хмельничини, українській національній революції та постаті Хмельницького. Для наших подальших роздумів немає особливої потреби здійснювати розлогий джерелознавчий та історіографічний аналіз, оскільки він, з одного боку, вимагає спеціальної концептуальної зосередженості, а з іншого - надалі ми будемо оперувати у необхідних випадках виключно загальновідомими, хрестоматійними аргументами, коли можна дозволити собі уникнути розлогих екскурсів щодо розгляду джерел та літератури. Зазначимо лише, що безпосередньо біографії Б.Хмельницького присвячена досить велика кількість робіт з різних наукових та ідеологічних таборів, серед яких в першу чергу слід назвати імена М.Грушевського, М.Кордуби, В.Липинського, І. Крип’якевича, В.Замлинського, Я.Дашкевича, В.Смолія, В.Степанкова, П.Гоя, Я.Федорука, В.Горобця, Т.Чухліба, В.Сергійчука, В.Серчика та багатьох інших.

Radical nephroureterectomy for pathologic T4 upper tract urothelial cancer: can oncologic outcomes be improved with multimodality therapy?

Purpose To report the outcomes of patients with pathologic T4 UTUC and investigate the potential impact of peri-operative chemotherapy combined with radical nephroureterectomy (RNU) and regional lymph node dissection (LND) on oncologic outcomes. Materials and Methods Patients with pathologic T4 UTUC were identified from the cohort of 1464 patients treated with RNU at 13 academic centers between 1987 and 2007. Oncologic outcomes were stratified according to utilization of perioperative systemic chemotherapy and regional LND as an adjunct to RNU. Results The study included 69 patients, 42 males (61%) with median age 73 (range 43-98). Median follow-up was 17 months (range: 6-88). Lymphovascular invasion was found in 47 (68%) and regional lymph node metastases were found in 31 (45%). Peri-operative chemotherapy was utilized in 29 (42%) patients. Patients treated with peri-operative chemotherapy and RNU with LND demonstrated superior oncologic outcomes compared to those not treated by chemotherapy and/or LND during RNU (3Y-DFS: 35% vs. 10%; P = 0.02 and 3Y-CSS: 28% vs. 14%; P = 0.08). In multivariate Cox regression analysis, administration of peri-operative chemotherapy and utilization of LND during RNU was associated with lower probability of recurrence (HR: 0.4, P = 0.01), and cancer specific mortality (HR: 0.5, P = 0.06). Conclusions Pathological T4 UTUC is associated with poor prognosis. Peri-operative chemotherapy combined with aggressive surgery, including lymph node dissection, may improve oncological outcomes. Our findings support the use of aggressive multimodal treatment in patients with advanced UTUC

Predictive Nomogram for Recurrence following Surgery for Nonmetastatic Renal Cell Cancer with Tumor Thrombus

Purpose Following surgery for nonmetastatic renal cell carcinoma with tumor thrombus the risk of recurrence is significant but variable among patients. The purpose of this study was to develop and validate a predictive nomogram for individual estimation of recurrence risk following surgery for renal cell carcinoma with venous tumor thrombus. Materials and Methods Comprehensive data were collected on patients with nonmetastatic renal cell carcinoma and thrombus treated at a total of 5 institutions from 2000 to 2013. Independent predictors of recurrent renal cell carcinoma from a competing risks analysis were developed into a nomogram. Predictive accuracy was compared between the development and validation cohorts, and between the nomogram and the UISS (UCLA Integrated Staging System, SSIGN (Stage, Size, Grade and Necrosis) and Sorbellini models. Results A total of 636 patients were analyzed, including the development cohort of 465 and the validation cohort of 171. Independent predictors, including tumor diameter, body mass index, preoperative hemoglobin less than the lower limit of normal, thrombus level, perinephric fat invasion and nonclear cell histology, were developed into a nomogram. Estimated 5-year recurrence-free survival was 49% overall. Five-year recurrence-free survival in patients with 0, 1, 2 and more than 2 risk factors was 77%, 53%, 47% and 20%, respectively. Predictive accuracy was similar in the development and validation cohorts (AUC 0.726 and 0.724, respectively). Predictive accuracy of the thrombus nomogram was higher than that of the UISS (AUC 0.726 vs 0.595, p = 0.001), SSIGN (AUC 0.713 vs 0.612, p = 0.04) and Sorbellini models (AUC 0.709 vs 0.638, p = 0.02). Conclusions We present a predictive nomogram for postoperative recurrence in patients with nonmetastatic renal cell carcinoma with venous thrombus. Improving individual postoperative risk assessment may allow for better design and analysis of future adjuvant clinical trials

The Impact of Previous Ureteroscopic Tumor Ablation on Oncologic Outcomes After Radical Nephrouretectomy for Upper Urinary Tract Urothelial Carcinoma

We investigated whether a history of endoscopic tumor ablation impacts oncologic outcomes after radical nephroureterectomy (RNU) for upper urinary tract urothelial carcinoma (UTUC). Using a multi-institutional database that contained patients who were treated with RNU, oncologic outcomes were assessed according to history of ureteroscopic tumor ablation. Disease-free survival (DFS) and cancer-specific survival (CSS) were estimated using the Kaplan-Meier survival analysis. Multivariate Cox regression analyses were performed to determine independent predictors of disease recurrence and cancer-specific mortality after RNU. The study included 1268 patients, 853 men and 415 women, with a mean age of 67.5 years (range 32-94 y) and 52.8 months median follow-up after RNU. A total of 175 (13%) patients underwent RNU after endoscopic tumor ablation and 1093 (87%) patients underwent RNU without a history of endoscopic ablation. The 5-year DFS and CSS rates were 72% and 77% in those with a history of tumor ablation vs 69% and 73% in those without a history of ablation (P = 0.171 and P = 0.365, respectively). In multivariate Cox regression analysis, history of ablation therapy was not associated with disease recurrence or cancer-specific mortality (hazard ratio [HR]: 0.79, P = 0.185 and HR: 0.7, P = 0.078, respectively). Our collaborative international efforts suggest that in selected patients, endoscopic tumor ablation does not adversely affect the recurrence and survival after subsequent RNU for UTUC. Our data support the continued role of ureteroscopic ablation of UTUC in appropriately selected patients.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/90497/1/end-2E2010-2E0396.pd

Advanced patient age is associated with inferior cancer-specific survival after radical nephroureterectomy

Study Type – Prognosis (case series) Level of Evidence 4To assess the impact of patient age on outcomes after radical nephroureterectomy (RNU) for upper tract urothelial carcinoma (UTUC).Data were collected on 1453 patients treated with RNU at 13 centres. Pathological slides were reviewed by dedicated genitourinary pathologists according to standardized criteria. Age at RNU was analysed both as a continuous and categorical variable (70 years were less likely to undergo lymphadenectomy and to receive adjuvant chemotherapy ( P  ≤ 0.026). In multivariable analyses, being older was associated with decreased all-cause (AC) survival (>60 years) and cancer-specific survival (CSS; >80 years) after controlling for the effects of standard pathological features ( P  ≤ 0.006). However, addition of age did not improve the predictive accuracy of a base model that included standard pathological features for prediction of either disease recurrence, AC survival or CSS.Being older at the time of RNU was associated with decreased survival. This finding could be due to a change in the biological potential of the tumour cell, a decrease in the host’s defence mechanisms, or differences in care patterns. Further work is needed to improve our understanding of UTUC outcomes in this growing segment of the population and to develop strategies to improve cancer control in the elderly.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/78588/1/j.1464-410X.2009.09072.x.pd

Tumour architecture is an independent predictor of outcomes after nephroureterectomy: a multi-institutional analysis of 1363 patients

To assess whether tumour architecture can help to refine the prognosis of patients treated with nephroureterectomy (NU) for urothelial carcinoma (UC) of the upper urinary tract (UT), as the prognostic value of tumour architecture (papillary vs sessile) in UTUC remains elusive. PATIENTS AND METHODS The study included 1363 patients with UTUC and treated with radical NU at 12 centres worldwide. All slides were re-reviewed according to strict criteria by genitourinary pathologists who were unaware of the findings of the original pathology slides and clinical outcomes. Gross tumour architecture was categorized as sessile vs papillary. RESULTS Papillary growth was identified in 983 patients (72.2%) and sessile growth in 380 (27.8%). The sessile growth pattern was associated with higher tumour grade, more advanced stage, lymphovascular invasion, and metastasis to lymph nodes (all P  < 0.001). In multivariable Cox regression analyses that adjusted for the effects of pathological stage, grade and lymph node status, tumour architecture (sessile or papillary) was an independent predictor of cancer recurrence (hazard ratio 1.5, P  = 0.002) and cancer-specific mortality (1.6, P  = 0.001). Adding tumour architecture increased the predictive accuracy of a model that comprised pathological stage, grade and lymph node status for predicting cancer recurrence and cancer-specific death by a minimal but statistically significant margin (gain in predictive accuracy 1% and 0.5%, both P  < 0.001). CONCLUSION The tumour architecture of UTUC is associated with established features of biologically aggressive disease, and more importantly, with prognosis after radical NU. Including tumour architecture in predictive models for disease progression should be considered, aiming to identify patients who might benefit from early systemic therapeutic intervention.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/72257/1/j.1464-410X.2008.08003.x.pd
