BACKGROUNDThe cytologic diagnosis of urothelial carcinoma (UC) of the upper urothelial tract (UT) is challenging. Using the UroVysion probe set adds diagnostic value for the detection of bladder cancer in voided urine. In instrumented UT specimens, the authors encountered positive UT cytology and fluorescence in situ hybridization (FISH) cases that did not demonstrate subsequent UT carcinoma.METHODSThe performance of cytology and FISH in the presence or absence of concomitant bladder cancer within 2 years was compared in 61 patients (112 samples) from 2003 through 2009. The mean follow‐up was 3.2 years. The authors also compared the performance of near‐tetrasomy versus hypertetrasomy. Biopsy confirmation of UTUC in 21 patients was considered the gold standard.RESULTSCytology alone was found to be poorly sensitive (38%) but highly specific (89%) for the detection of UTUC. FISH was found to increase the sensitivity of cytology and decrease specificity. Tetrasomy FISH resulted in many false‐positive cases. Other false‐positive FISH results were likely due to the presence of bladder cancer cells contaminating the UT specimen.CONCLUSIONSCaution should be used when evaluating instrumented urine specimens of the UT from patients with a previous history of bladder carcinoma, and tetrasomy FISH results should not be interpreted as abnormal because it significantly lowers the specificity of the test. The combination of cytology and FISH appears to have good specificity while maintaining good sensitivity in evaluating UTUC when using modified scoring criteria for the appropriate patient population.

Objectives To evaluate short‐term outcomes of holmium laser enucleation of the prostate ( HoLEP ) and photoselective vaporisation of the prostate ( PVP ) in patients with benign prostatic hyperplasia (BPH) and chronic urinary retention ( CUR ). Patients and Methods A retrospective chart review was performed of all patients with CUR who underwent HoLEP or PVP at our institution over a 3‐year period. CUR was defined as a persistent post‐void residual urine volume ( PVR ) of >300 mL or refractory urinary retention requiring catheterisation. Results We identified 72 patients with CUR who underwent HoLEP and 31 who underwent PVP . Preoperative parameters including median catheterisation duration (3 vs 5 months, P = 0.71), American Urological Association Symptom Index score ( AUASI ; 18 vs 21, P = 0.24), and PVR (555 vs 473 mL, P = 0.096) were similar between the HoLEP and PVP groups. The HoLEP group had a larger prostate volume (88.5 vs 49 mL, P < 0.001) and higher PSA concentration (4.5 vs 2.4 ng/mL, P = 0.001). At median 6‐month follow‐up, 71 (99%) HoLEP patients and 23 (74%) PVP patients were catheter‐free ( P < 0.001). Of the voiding patients, postoperative AUASI (3 vs 4, P = 0.06), maximum urinary flow rate (23 vs 18 mL/s, P = 0.28) and PVR (56.5 vs 54 mL, P = 1.0) were improved in both groups. Conclusions Both HoLEP and PVP are effective at improving urinary parameters in men with CUR . Despite larger prostate volumes, HoLEP had a 99% successful deobstruction rate, thus rendering patients catheter‐free.

BackgroundThe use of hematopoietic progenitor cell (HPC) transplant has risen over the past two decades. A variety of adverse events (AEs) of varying severity have been noted during HPC infusions. These AEs have been associated with several factors such as the amount of dimethyl sulfoxide and white blood cells in the HPC product. We performed a single‐institution retrospective analysis to determine the effect of two different HPC infusion techniques, manual push with syringes versus infusion from bags with the aid of gravity, on the occurrence of infusion‐related AEs.Study Design and MethodsInfusions between December 2008 and November 2010 involving peripheral blood HPCs were reviewed. Pertinent clinical and HPC product–related information was recorded. Data were analyzed to determine the incidence of infusion‐related AEs and its association with patient and product‐related variables.ResultsWe found 461 AEs in 645 patients during the study period. A total of 325 (50%) experienced at least one AE. Flushing was the most common type of AE followed by nausea and hypertension. The use of syringe infusion was more commonly associated with AEs (odds ratio, 1.82 [95% confidence interval, 1.32‐2.50]; p = 0.002). Other independent risk factors were cryopreserved products and the amount of polymorphonuclear leukocytes in the product.ConclusionTo our knowledge, this is the first study examining the effect of two different infusion techniques on infusion‐related AEs. Our findings suggest that the use of bags for infusion protected the patients from AEs.

Abstract Atypical hyperplasia is a high-risk premalignant lesion of the breast, but its biology is poorly understood. Many believe that atypical ductal hyperplasia (ADH) is a direct precursor for low-grade ductal breast cancer, whereas atypical lobular hyperplasia (ALH) serves as a risk indicator. These assumptions underlie current clinical recommendations. We tested these assumptions by studying the characteristics of the breast cancers that develop in women with ADH or ALH. Using the Mayo Benign Breast Disease Cohort, we identified all women with ADH or ALH from 1967 to 2001 and followed them for later breast cancers, characterizing side of breast cancer versus side of atypia; time to breast cancer; type, histology, and grade of breast cancer, looking for patterns consistent with precursors versus risk indicators. A total of 698 women with atypical hyperplasia were followed a mean of 12.5 years; 143 developed breast cancer. For both ADH and ALH, there is a 2:1 ratio of ipsilateral to contralateral breast cancer. The ipsilateral predominance is marked in the first 5 years, consistent with a precursor phenotype for both ADH and ALH. For both, there is a predominance of invasive ductal cancers with 69% of moderate or high grade. Twenty-five percent are node positive. Both ADH and ALH portend risk for ductal carcinoma in situ and invasive breast cancers, predominantly ductal, with two thirds moderate or high grade. The ipsilateral breast is at especially high risk for breast cancer in the first 5 years after atypia, with risk remaining elevated in both breasts long term. ADH and ALH behave similarly in terms of later breast cancer endpoints. Cancer Prev Res; 7(2); 211–7. ©2014 AACR.

Purpose To evaluate the personal and professional characteristics associated with career satisfaction and burnout among US oncologists. Methods Between October 2012 and March 2013, the American Society of Clinical Oncology conducted a survey of US oncologists evaluating burnout and career satisfaction. The survey sample included equal numbers of men and women and represented all career stages. Results Of 2,998 oncologists contacted, 1,490 (49.7%) returned surveys (median age of respondents, 52 years; 49.6% women). Among the 1,117 oncologists (37.3% of overall sample) who completed full-length surveys, 377 (33.8%) were in academic practice (AP) and 482 (43.2%) in private practice (PP), with the remainder in other settings. Oncologists worked an average of 57.6 hours per week (AP, 58.6 hours per week; PP, 62.9 hours per week) and saw a mean of 52 outpatients per week. Overall, 484 oncologists (44.7%) were burned out on the emotional exhaustion and/or depersonalization domain of Maslach Burnout Inventory (AP, 45.9%; PP, 50.5%; P = .18). Hours per week devoted to direct patient care was the dominant professional predictor of burnout for both PP and AP oncologists on univariable and multivariable analyses. Although a majority of oncologists were satisfied with their career (82.5%) and specialty (80.4%) choices, both measures of career satisfaction were lower for those in PP relative to AP (all P < .006). Conclusion Overall career satisfaction is high among US oncologists, albeit lower for those in PP relative to AP. Burnout rates among oncologists seem similar to those described in recent studies of US physicians in general. Those oncologists who devote the greatest amount of their professional time to patient care seem to be at greatest risk for burnout.
