Renal cell carcinoma (RCC) metastasis portends a poor prognosis and cannot be reliably predicted. Early determination of the metastatic potential of RCC may help guide proper treatment. We analyzed ...microRNA (miRNA) expression in clear cell RCC (ccRCC) for the purpose of developing a miRNA expression signature to determine the risk of metastasis and prognosis. We used the microarray technology to profile miRNA expression of 78 benign kidney and ccRCC samples. Using 28 localized and metastatic ccRCC specimens as the training cohort and the univariate logistic regression and risk score methods, we developed a miRNA signature model in which the expression levels of miR-10b, miR-139-5p, miR-130b and miR-199b-5p were used to determine the status of ccRCC metastasis. We validated the signature in an independent 40-sample testing cohort of different stages of primary ccRCCs using the microarray data. Within the testing cohort patients who had at least 5 years follow-up if no metastasis developed, the signature showed a high sensitivity and specificity. The risk status was proven to be associated with the cancer-specific survival. Using the most stably expressed miRNA among benign and tumorous kidney tissue as the internal reference for normalization, we successfully converted his signature to be a quantitative PCR (qPCR)-based assay, which showed the same high sensitivity and specificity. The 4-miRNA is associated with ccRCC metastasis and prognosis. The signature is ready for and will benefit from further large clinical cohort validation and has the potential for clinical application.

Abstract Background Comprehensive and standardized reporting of adverse events after robot-assisted radical cystectomy (RARC) and urinary diversion for bladder cancer is necessary to evaluate the ...magnitude of morbidity for this complex operation. Objective To accurately identify and assess postoperative morbidity after RARC using a standardized reporting system. Design, setting, and participants A total of 241 consecutive patients underwent RARC, extended pelvic lymph node dissection, and urinary diversion between 2003 and 2011. In all, 196 patients consented to a prospective database, and they are the subject of this report. Continent diversions were performed in 68% of cases. Outcome measurements and statistical analysis All complications within 90 d of surgery were defined and categorized by a five-grade and 10-domain modification of the Clavien system. Univariable and multivariable logistic regression analyses were used to identify predictors of complications. Grade 1–2 complications were categorized as minor, and grade 3–5 complications were categorized as major. All blood transfusions were recorded as grade ≥2. Results and limitations Eighty percent of patients (156 of 196 patients) experienced a complication of any grade ≤90 d after surgery. A total of 475 adverse events (113 major) were recorded, with 365 adverse events (77%) occurring ≤30 d after surgery. Sixty-eight patients (35%) experienced a major complication within the first 90 d. Other than blood transfusions given (86 patients 43.9%), infectious, gastrointestinal, and procedural complications were the most common, at 16.2%, 14.1%, and 10.3%, respectively. Age, comorbidity, preoperative hematocrit, estimated blood loss, and length of surgery were predictive of a complication of any grade, while comorbidity, preoperative hematocrit, and orthotopic diversion were predictive of major complications. The 90-d mortality rate was 4.1%. The main limitation is lack of a control group. Conclusions Analysis of postoperative morbidity following RARC demonstrates a considerable complication rate, though the rate is comparable to contemporary open series that followed similar reporting guidelines. This finding reinforces the need for complete and standardized reporting when evaluating surgical techniques and comparing published series.
Population-based practice patterns in the United States reveal continent diversions are only performed in 8%-10.4% of patients.1-4 Ideally, for patients undergoing radical cystectomy the choice of ...urinary diversion should be influenced by clinical factors and patient preference, with discussions surrounding quality of life. Unfortunately, receipt of continent diversion has been shown to be influenced by a plethora of other factors such as surgeon preference/training, geography, socioeconomic status, gender, and hospital volume.1-3 Thus, by providing detailed instruction and long-term follow-up, we hope to mitigate some of these disparities by changing the perceptions regarding feasibility and complications of continent diversions.
To provide step-by-step instruction and to report long-term clinical outcomes in bladder cancer patients receiving an Indiana pouch continent cutaneous urinary diversion (CCUD) after robot-assisted radical cystectomy.
After Institutional Review Board approval, a prospectively maintained bladder cancer database was queried for patients with T1-T4, N0-N1, M0 bladder cancer undergoing radical cystectomy with CCUD at a tertiary referral center from 2004 to 2020.
Complications at 30- and 90-day were recorded according to the Clavien-Dindo classification. Continence rates were recorded by chart review.
A total of 97 patients were included with a median follow-up of 93months. Clinically, 91.8% had ≤T2 disease and 29.9% received neoadjuvant chemotherapy. The median length of surgery was 8.0 hours, length of hospital stay was 8.3days, and urinary continence rate was 99.0%. The overall complication rate was 73.2% and 76.5% at 30- and 90-day, respectively. The major complication rate (Clavien III-V) was 17.5% at 30-day and 22.7% at 90-day. The most common major complications were abdominal infection and uretero-colonic stricture. The readmission rate was 21.4% and median overall survival was 108months.
CCUD provides exceptional functional outcomes with acceptable complication rates compared to other diversion types. CCUD is a reliable reconstructive option and with this step-by-step video as a reference, we hope it will be offered to more patients.
More than 90 million Americans are struggling to live with serious illness and are in need of palliative and end-of-life care. Yet, many novice RNs have not been adequately prepared during their ...undergraduate programs to care for them.
A large southwestern Magnet comprehensive cancer center piloted integrating the End-of-Life Nursing Education Consortium (ELNEC)-Undergraduate Curriculum into their nurse residency program during 2018 with 55 new RNs.
A pre-and posteducation evaluation questionnaire measured comfort with caring for patients with serious illness, competence, and knowledge in six areas of palliative care. All eight evaluation questions demonstrated statistically significant improvement posteducational intervention. Many nurse residents reported a change in clinical practice 1 month posteducation.
The nurse residency is an opportune training time to prepare novice nurses to provide primary palliative care for all patients with serious illness and their families. J Contin Educ Nurs. 2020;51(6):280-286..
To assess efficacy and safety of a novel cystoscopic technique for definitive repair of bladder neck contracture (BNC) and vesicourethral anastomotic stenosis (VUAS).
A retrospective review of ...patients who underwent a transurethral incision with transverse mucosal realignment between July 2019 and December 2020 by a single surgeon was completed. This is novel procedure of incising a scar cystoscopically and using a laparoscopic suturing device transurethrally to bring healthy bladder mucosa across the defect, like a YV plasty. Patients were only included if they had ≥4 months follow-up. Surgical success was defined as ability to pass a 17 French flexible cystoscope through the previously stenotic segment at 4 month follow up.
Nineteen patients with a median follow-up of 6 months were included in this analysis. Etiology of posterior urethral stenosis was 53% from VUAS and 47% from BNC, with 32% of patients having prior pelvic radiation. Success was achieved in 89% of patients after 1 procedure and 100% of patients achieved success after a second procedure. There was no de novo incontinence or major complications.
Transurethral incision with transverse mucosal realignment for VUAS and BNC has a high success rate after only 1 procedure. This is the first reported series of an endoscopic Y-V plasty type repair for BNC and VUAS. Longer term follow up to ensure durability and reporting from other institutions will be needed to establish reproducibility.
Purpose Minimally invasive surgical treatment for bladder cancer has gained popularity but standardized data on complications are lacking. Urinary diversion type contributes to complications and to ...our knowledge diversion types after minimally invasive cystectomy have not yet been compared. We evaluated perioperative complications stratified by urinary diversion type in patients treated with robot-assisted radical cystectomy. Materials and Methods We analyzed the records of 209 consecutive patients who underwent robot-assisted radical cystectomy at our institution from 2003 to 2012 with respect to perioperative complications, including severity, time period (early and late) and diversion type. All complications were reviewed by academic urologists. Urinary diversion was also done. As outcome measurements and statistical analysis, univariate and multivariate logistic regression models were used to determine predictors of various complications. Results The American Society of Anesthesiologists® (ASA) score was 3 or greater in 80% of patients and continent diversion was performed in 68%. Median followup was 35 months. Within 90 days 77.5% of patients experienced any complication and 32% experienced a major complication. The 90-day mortality rate was 5.3%. Most complications were gastrointestinal, infectious and hematological. On multivariate analysis patients with ileal conduit diversion had a decreased likelihood of complications compared to patients with Indiana pouch and orthotopic bladder substitute diversion despite the selection of a more comorbid population for conduit diversion. Continent diversion was associated with a higher likelihood of urinary tract infection. Our results are comparable to those of previously reported open and minimally invasive cystectomy series. Conclusions Open or minimally invasive cystectomy is a complex, morbid procedure. Urinary diversion is a significant contributor to complications, as is patient comorbidity. Although patients with an ileal conduit had more comorbidities, they experienced fewer complications than those with an orthotopic bladder substitute or Indiana pouch diversion.
BACKGROUND:Family caregivers are a key communication source for nurses, and there is a need to provide communication skill building for caregivers.
OBJECTIVE:A pilot study was conducted to determine ...feasibility and use of a communication coaching telephone intervention aimed at improving caregiver confidence in communication and reducing psychological distress.
METHODS:A printed communication guide for caregivers and a 1-time communication coaching call delivered by a research nurse were provided to caregivers. Recruitment and attrition, implementation and content of coaching calls, caregiver outcomes, and satisfaction with intervention were analyzed.
RESULTS:Twenty caregivers were recruited across 4 cohorts—diagnosis, treatment, survivorship, and end of life—with recruitment greater than 70%. Caregiver calls averaged 37 minutes, and most caregivers reported communication challenges with family members. Caregiver action plans revealed a need to develop communication skills to ask for help and share information. Caregivers reported satisfaction with the print guide, and 90% of caregivers followed through with their action plan, with 80% reporting that the action plan worked. Caregiver confidence in communication with healthcare providers was improved, except for caregivers of cancer survivors.
CONCLUSIONS:Recruitment and attrition rates demonstrate feasibility of the intervention. Caregivers reported that the communication coaching telephone intervention was considered valuable and they were able to implement a communication action plan with others.
IMPLICATIONS FOR PRACTICE:Lessons were learned about intervention content, namely, that nurses can help caregivers learn communication strategies for asking for help, sharing cancer information, and initiating self-care.
To determine whether use of an antibiotic-irrigating wound protector (AWP) reduces infectious complications after robotic radical cystectomy with extracorporeal urinary diversion (RCUD).
A ...prospectively maintained bladder cancer database was queried for patients undergoing robotic RCUD at a tertiary referral center one year prior to implementing an AWP and one year after (2018–2020). All diversions were performed extra-corporally. 92 patients total. 46 consecutive patients using a traditional wound protector (TWP) and 46 consecutive with an AWP. Infections were classified as symptomatic urinary tract infection, blood stream infection, and surgical site infection. The incidence of infectious complications at 30- and 90-days were compared.
Baseline patient characteristics between the 2 groups showed no statistically significant differences. The overall complication rate was 65.2% in the TWP group and 26.1% in the AWP group at 30-days, and 67.4% vs 30.4% at 90-days. Focusing on infections, the 30-day complication rate was 30.4% in the TWP group compared to 6.5% in the AWP group (P =.003). This pattern persisted at 90-days with 37.0% in the TWP group compared to 6.5% in the AWP group (P =.004). Most complications were symptomatic UTI and blood stream infections, 14/24 (58%), requiring parenteral antibiotic treatment.
We provide preliminary data showing use of an AWP can reduce infectious complications after RCUD. While larger prospective studies are warranted, our findings are a significant step towards decreasing morbidity of an already highly morbid procedure.
To investigate which preoperative findings portend poor improvement in storage symptoms in patients undergoing plasma kinetic enucleation of prostate (PKEP).
A single surgeon series of patients who ...had undergone PKEP with minimum 1 year follow up were evaluated. Patients were grouped into those with less than 33% improvement in storage symptoms (LIS) according to the international prostate symptom score (IPSS) and those with greater than 33% improvement in storage symptoms (GIS). Pre and postoperative factors were evaluated, along with IPSS, storage symptoms percentage (the total from frequency, urgency and nocturia divided by the total IPSS), bother index, and post void residual (PVR) at 6 weeks, 4 months, and yearly.
Two hundred sixty-eight patients had a minimum 1 year of follow up and had completed the IPSS. IPSS and bother index improved significantly from preoperatively to all time points post operatively in both groups, but the difference was greater in the GIS group. Patients in the GIS group had significantly larger prostates, more prostatic ingrowth, higher preoperative PVR, and a higher overall IPSS compared to the LIS group. Those in the LIS group had a higher incidence of prior prostate surgery, and a higher BMI. However, storage symptom percentages were equal between the GIS and LIS groups at all time points.
Greater prostatic ingrowth, larger prostate volume, higher preoperative PVR volume, and a higher overall IPSS was associated with greater improvement in storage symptoms. Prior prostate surgery and higher BMI portend less improvement in storage symptoms.
