RESUMO

OBJECTIVES: Patients with cancer who are at a transition to Phase I investigational treatments have been identified as an underserved population with regard to palliative care. This disease transition is often accompanied by spiritual and existential concerns. The study objective was to conduct a secondary analysis of data from a larger study testing a palliative care intervention. This paper reports the findings of this secondary focus on the spiritual needs of this population. METHODS: Patients (n = 479) were accrued to this study prior to initiating a Phase I clinical trial with data collected at baseline, and 4, 12, and 24 week follow-up. RESULTS: Qualitative data revealed that the transition to Phase 1 trial participation is a time of balancing hope for extended life with the reality of advancing disease. Quantitative results demonstrated increased spirituality over time in both religious- and non-religious-affiliated patients. CONCLUSIONS: Patients entering Phase I trials have important spiritual needs as they face treatment decisions, advancing disease, and often mortality. Spiritual care should be provided to seriously ill patients as a component of quality care.

RESUMO

OBJECTIVE: To report our experience with ureteroenteric anastomotic revision as initial treatment of stricture after urinary diversion. METHODS: An institutional review board-approved retrospective study was carried out. A total of 41 patients who underwent primary ureteroenteric anastamotic revision were identified between 2007 and 2015. Data analyzed included patient characteristics, type of diversion, estimated blood loss, operative time, change in renal function, length of stay, postoperative complications and time with nephrostomy/stent. Success of revision was defined as an improvement in hydronephrosis on radiographic imaging and/or reflux during pouchogram. Predictors of length of stay and complications were analyzed using analysis of covariance. RESULTS: A total of 50 renal units were revised with a success rate of 100%. The median length of stay was 6 days (2-16 days). There were a total of 15 complications (one major, 14 minor) in 14 patients (33% 30-day complication rate). The most common were wound infection (n = 4) and arrhythmia (n = 4). Robotic revision (n = 5) had a median length of stay of 3 days (2-4) with no complications. CONCLUSIONS: Primary ureteroenteric anastomotic revisions have an excellent success rate at an experienced center and might obviate the need for multiple interventions. Open revision is associated with mostly minor complications. Robotic revision might reduce the morbidity of open revision in select cases.

RESUMO

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.

RESUMO

BACKGROUND: 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. OBJECTIVE: 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. DESIGN, SETTING, AND PARTICIPANTS: 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. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Complications at 30- and 90-day were recorded according to the Clavien-Dindo classification. Continence rates were recorded by chart review. RESULTS AND LIMITATIONS: 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. CONCLUSION: 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.

RESUMO

UNLABELLED: WHAT'S KNOWN ON THE SUBJECT? AND WHAT DOES THE STUDY ADD?: Extended pelvic lymphadenectomy is the present standard of care according to European Association of Urology guidelines. Extended dissection improves staging, removes more metastatic lymph nodes, and potentially has therapeutic benefits. Previous reports have examined the morbidity of extended dissection compared with a more limited dissection in the open and laparoscopic setting. While some have suggested an increased complication rate with extended node dissection, others have not. This represents the first study focused on comparing the complications associated with the extent of node dissection using the modified Clavien system and Martin criteria in the literature on robot-assisted surgery. In a single surgeon series, we found no statistically significant differences in complications. With careful anatomic dissection, robot-assisted extended lymph node dissection can be performed safely and effectively, although operating time and length of hospital of stay are slightly increased. OBJECTIVES: To compare the perioperative course of patients undergoing robot-assisted limited lymph node dissection (LLND) or extended lymph node dissection (ELND) for prostate cancer. To examine the differential lymph node counts and rates of detection of lymph node metastases. PATIENTS AND METHODS: Between 2008 and 2012, 406 consecutive patients with D'Amico intermediate- or high-risk prostate cancer underwent either bilateral LLND (n = 204) or ELND (n = 202) and robot-assisted laparoscopic radical prostatectomy by a single surgeon. The region of dissection was the obturator fossa for LLND, while ELND included, in addition, the common iliac, external iliac and internal iliac lymph nodes. All complications within 90 days of surgery were recorded according to a modified Clavien system. Clinical variables were summarized and compared. Logistic regression was used to identify predictors of complications. RESULTS: There were no differences in demographics when comparing patients who underwent ELND with those who underwent LLND. The median operating time was 3.0 h for the ELND cohort and 2.8 h in the LLND cohort (P < 0.001). Intraoperative blood loss was 200 mL in both cohorts. Hospital stay was longer for a small percentage of patients in the ELND cohort, with 75% of ELND patients and 85% of LLND patients staying 1 day (P = 0.004). No significant difference was found in the overall or major complication rates between LLND (21.6% overall; 6.9% major) and ELND (22.8% overall; 4.5% major). No difference was seen in the symptomatic lymphocele rate between LLND and ELND, 2.9 vs 2.5%, respectively. Overall, the lymph-node-positive rate was 12% compared with 4% for the ELND and LLND groups, respectively (P = 0.002). A higher Charlson comorbidity index score was associated with the development of major complications. CONCLUSIONS: ELND at the time of robot-assisted radical prostatectomy can be performed safely with minimal additional morbidity. Long-term oncological and functional outcomes require further study.

RESUMO

INTRODUCTION: The objective of our study was to determine whether dorsal venous complex (DVC) control technique influences positive apical margins following robotic assisted laparoscopic radical prostatectomy (RALRP). MATERIALS AND METHODS: One thousand fifty-eight patients who underwent RALRP at City of Hope from June 2007 to October 2009 were assessed. Endoscopic stapling and suture ligature of the DVC were compared. Positive apical margins were identified and compared based on DVC-control technique. Recurrence probability was estimated using the Kaplan-Meier method, and logistic regression analysis was used to predict the odds of positive apical margins. RESULTS: Of 1058 patients, 633 (60%) underwent endoscopic stapling, and 425 (40%) had suture ligature. The groups had similar baseline characteristics including age and body mass index. We observed a statistically different PSA (5.4 ng/mL versus 5.2 ng/mL, p = 0.03) and operative time (2.8 hours versus 2.7 hours, p = 0.02) between stapling and suture groups, but the actual difference was small. Operative time, Gleason score, pathologic stage, and overall positive margin rates were not significantly different between groups. Positive apical margins were observed in 39 (6%) and 27 (6%) patients in the staple and suture groups, respectively. Multivariate analysis showed that the positive apical margin rate was greater in patients with higher pathologic stage and final pathological Gleason score. CONCLUSIONS: During RALRP, there is no difference in positive apical margin rate when the DVC is controlled using either endoscopic stapling or suture ligature. However, patients with a higher pathologic stage and final pathologic Gleason score are at higher risk for positive apical surgical margins.

RESUMO

Purpose: Lower urinary tract symptoms among adult men can significantly impact quality of life. We evaluated complications based on prostate size following plasmakinetic enucleation of the prostate. Materials and Methods: Patients were grouped into the small prostate group (SPG, <75 g) and large prostate group (LPG, >75 g) based on preoperative imaging. Patient data on demographics, comorbidities, preoperative international prostate symptom score (IPSS), bother index (BI), prostate-specific antigen (PSA) if indicated, postvoid residual volume (PVR), indwelling catheter or self-catheterization status, and any prior surgical intervention were evaluated. Postoperative IPSS, BI, and PVR values were assessed at 6 weeks, 4 months, and yearly. Postoperative urge urinary incontinence (UUI), stress urinary incontinence (SUI), and pad use were assessed. Results: Between September 2015 and December 2020, 296 patients who underwent bipolar enucleation with minimum follow-up of 4 months were evaluated. Postoperative IPSS, BI, PVR, and PSA values at all time points were significantly decreased compared with preoperative values (p < 0.05). There was no significant difference in the complications between groups. Univariable and multivariable analysis found that size <75 g was predictive of stricture formation and bladder neck contracture (BNC). UUI was more common at 6 weeks in the SPG, and SUI was more common at 6 weeks in the LPG, but no difference was noted at the 4-month and 1-year time points. Pad use was equal between the two groups at all time points. Conclusions: Plasmakinetic enucleation of the prostate provides an effective treatment option for prostates of all sizes; however, prostates <75 g have a higher rate of BNC and urethral strictures compared with those >75 g.

RESUMO

OBJECTIVE: To determine whether use of an antibiotic-irrigating wound protector (AWP) reduces infectious complications after robotic radical cystectomy with extracorporeal urinary diversion (RCUD). METHODS: 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. RESULTS: 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. CONCLUSION: 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.

RESUMO

OBJECTIVE: To investigate which preoperative findings portend poor improvement in storage symptoms in patients undergoing plasma kinetic enucleation of prostate (PKEP). METHODS: 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. RESULTS: 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. CONCLUSION: 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.

RESUMO

OBJECTIVE: To assess efficacy and safety of a novel cystoscopic technique for definitive repair of bladder neck contracture (BNC) and vesicourethral anastomotic stenosis (VUAS). METHODS: 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. RESULTS: 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. CONCLUSION: 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.

RESUMO

Background: Phase 1 clinical trials remain vital for oncology care. Patients on these trials require supportive care for quality-of-life (QOL) concerns. Objective: To test a Palliative Care Intervention (PCI) for patients with solid tumors enrolled in Phase I therapeutic trials with a priori hypothesis that psychological distress, QOL, satisfaction, symptoms, and resource utilization would be improved in the PCI group. Design: This unblinded randomized trial compared the PCI with usual care in patients accrued to Phase I Clinical Trials. Subjects (n = 479) were followed for 24 weeks, with 12 weeks as the primary outcome. Setting: Two Comprehensive Cancer Centers in the United States. Subjects: A consecutive sample, 21 years or older, English fluency, with solid tumors initiating a Phase 1 trial. Measurements: Psychological Distress (Distress Thermometer), QOL total and subscales (FACT-G), satisfaction (FAM-CARE), survival, and resource utilization (chart audit). Results: PCI subjects showed improved Psychological Distress (-0.47, p = 0.015) and Emotional Well-Being (0.81, p = 0.045), with differences on variables of QOL and distress between sites. High rates of symptom-management admissions (41.3%) and low rates of Advance Directive completion (39.0%), and hospice enrollment (30.7%), despite a median survival in both groups of 10.1 months from initiating a Phase 1 study. Conclusions: A nurse-delivered PCI can improve some QOL outcomes and distress for patients participating in Phase 1 trials. Greater integration of PC is needed to provide quality care to these patients and to support transitions from treatment to supportive care, especially at the end of life.

RESUMO

The presence of BRCA pathogenic variants (PVs) in triple-negative breast cancer (TNBC) is associated with a distinctive genomic profile that makes the tumor particularly susceptible to DNA-damaging treatments. However, patients with BRCA PVs can develop treatment resistance through the appearance of reversion mutations and restored BRCA expression. As copy-number variants (CNV) could be less susceptible to reversion mutations than point mutations, we hypothesize that carriers of BRCA CNVs may have improved survival after treatment compared to carriers of other BRCA PVs or BRCA wild-type. Women diagnosed with stage I-III TNBC at ≤50 years at a cancer center in Mexico City were screened for BRCA PVs using a recurrent PV assay (HISPANEL; 77% sensitivity). The recurrence-free (RFS) and overall survival (OS) were compared according to mutational status. Among 180 women, 17 (9%) were carriers of BRCA1 ex9-12del CNV and 26 (14%) of other BRCA PVs. RFS at ten years for the whole cohort was 79.2% (95% CI 72.3-84.6%), with no significant differences according to mutational status. 10-year OS for the entire cohort was 85.3% (95%CI: 78.7-90.0%), with BRCA CNV carriers demonstrating numerically superior OS rates other PV carriers and non-carriers (100% vs. 78.6% and 84.7%; log-rank p=0.037 and p=0.051, respectively). This study suggests that BRCA1 ex9-12del CNV carriers with TNBC may have a better OS, and supports the hypothesis that the genotype of BRCA PVs may influence survival by limiting treatment resistance mediated by reversion mutations among CNV carriers.

RESUMO

BACKGROUND: 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. METHOD: 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. RESULTS: 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. CONCLUSION: 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.

RESUMO

Antibody fragments with optimized pharmacokinetic profiles hold potential for detection and therapy of tumor malignancies. We studied the behavior of three anti-carcinoembryonic antigen (CEA) single-chain Fv-Fc (scFv-Fc) variants (I253A, H310A, and H310A/H435Q; Kabat numbering system) that exhibited differential serum persistence. Biodistribution studies done on CEA-positive tumor xenografted mice revealed that the 111In-labeled I253A fragment with the slowest clearance kinetics (T1/2beta, 27.7 h) achieved the highest tumor uptake (44.6% ID/g at 24 h), whereas the radiometal-labeled H310A/H435Q fragment with the most rapid elimination (T1/2beta, 7.05 h) reached a maximum of 28.0% ID/g at 12 h postinjection. The H310A protein was characterized by both intermediate serum half-life and tumor uptake. The 111In-based biodistribution studies showed that all three fragments were eliminated primarily through the liver, and hepatic radiometal activity correlated with the rate of fragment clearance. The 111In-labeled H310A/H435Q protein exhibited the highest liver uptake (23.5% ID/g at 24 h). Metabolism of the 125I-labeled scFv-Fc proteins resulted in low normal organ activity. Finally, the 125I/111In biodistribution data allowed for dose estimations, which suggest the 131I-labeled scFv-Fc H310A/H435Q as a promising candidate for radioimmunotherapy.

RESUMO

OBJECTIVES: To investigate delays to neoadjuvant chemotherapy (NAC) and radical cystectomy (RC) and their effect on outcomes in a large national registry of patients with localized muscle invasive bladder cancer. PATIENTS AND METHODS: Within the National Cancer Database (2004-2014), we identified 2,227 patients who underwent NAC and RC for cT2-T4aN0M0 urothelial carcinoma of the bladder. Times from diagnosis to treatments were tested for association with overall survival and pathologic outcomes, using Cox models, and restricted cubic splines regression. RESULTS: Median times from diagnosis to NAC and RC were 39 days (interquartile range: 26-56) and 155 days (interquartile range: 131-185), respectively. Time to NAC and time to RC were not associated with overall survival in the complete cohort, as well as in subgroups of responders and nonresponders to NAC. Overall, 916 patients (41%) were upstaged after RC, including 485 patients (22%) with positive lymph nodes. We identified delay to NAC ≥8 weeks as a significant cut-off point to predict the risk of upstaging in multivariable analysis (odds ratio: 1.27; 95% confidence interval: 1.02-1.59; P = 0.031). Black race, Medicaid insurance, and academic facilities were associated with a higher risk of delayed treatment. CONCLUSION: After diagnosis of muscle invasive bladder cancer, NAC should be initiated as soon as possible and no more than 8 weeks to prevent upstaging. There is no evidence to support avoiding NAC due to concerns of delayed RC that was generated from surgery alone studies, as long as RC is performed within 7 months from initial diagnosis.

RESUMO

BACKGROUND: Ischemia is thought to contribute to benign ureteroenteric stricture (UES) after radical cystectomy with urinary diversion (RCUD). Our institution adopted the use of ureteral perfusion assessment during all RCUDs using real-time indocyanine green angiography using the SPY fluorescence imaging platform (Stryker Corp., Kalamazoo, MI, USA). This guides the location of ureteral transection prior to ureteroenteric anastomosis. We sought to compare UES rates before and after adoption of SPY. METHODS: A retrospective chart review was undertaken for the first 47 consecutive cases of RCUD using SPY as well as the previous 47 consecutive cases, which were performed without SPY. Fisher's exact and Wilcoxon rank-sum tests were used to compare benign UES rates and the length of ureter excised during anastomosis. A p < 0.05 indicated statistical significance. RESULTS: Median follow up was 12.0 months for SPY cases and 24.3 months for non-SPY cases. The UES rate for SPY RCUDs was 0% (0/93 ureters) compared with 7.5% (7/93 ureters) for non-SPY RCUDs (p = 0.01). Amongst SPY RCUDs, 86 ureters had no hydronephrosis and 7 had mild hydronephrosis with reflux on loopogram. A total of 34.4% of ureters (32/93) had poor distal perfusion, requiring a more proximal anastomosis. The median length excised for ureters with poor distal perfusion was 3.8 cm, compared with 2.2 cm for ureters with good distal perfusion (p < 0.0001). No complications attributable to the use of SPY were noted. CONCLUSION: Use of SPY to assess ureteral perfusion was associated with a decrease in the UES rate after RCUD. A total of 34.4% of ureters demonstrated poor distal perfusion, requiring a significantly more proximal ureteroenteric anastomosis.

RESUMO

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.

RESUMO

Tumor invasion into draining lymph nodes, especially sentinel lymph nodes (SLNs), is a key determinant of prognosis and treatment in breast cancer as part of the TNM staging system. Using multicolor histology and quantitative image analysis, we quantified immune cells within SLNs from a discovery cohort of 76 breast cancer patients. We found statistically more in situ CD3+ T cells in tumor negative vs. tumor positive nodes (mean of 8878 vs. 6704, respectively, p = 0.006), but no statistical difference in CD20+ B cells or CD1a+ dendritic cells. In univariate analysis, a reduced hazard was seen with a unit increase in log CD3 with HR 0.49 (95% CI 0.30-0.80) and log CD20 with HR 0.37 (95% CI 0.22-0.62). In multivariate analysis, log CD20 remained significant with HR 0.42 (95% CI 0.25-0.69). When restricted to SLN tumor negative patients, increased log CD20 was still associated with improved DFS (HR = 0.26, 95% CI 0.08-0.90). The CD20 results were validated in a separate cohort of 21 patients (n = 11 good outcome, n = 10 poor outcome) with SLN negative triple-negative breast cancer (TNBC) ("good" mean of 7011 vs. "poor" mean of 4656, p = 0.002). Our study demonstrates that analysis of immune cells within SLNs, regardless of tumor invasion status, may provide additional prognostic information, and highlights B cells within SLNs as important in preventing future recurrence.

RESUMO

INTRODUCTION: Evidence for the use of perioperative chemotherapy (PC) in upper tract urothelial carcinoma (UTUC) is largely derived from level I evidence for invasive urothelial carcinoma of the bladder (UCB). There has been an increase in PC for urothelial carcinoma of the bladder, as it has disseminated into clinical practice. Therefore, we sought to not only analyze trends in the utilization of PC in UTUC, but also assess factors associated with its use in a large cancer registry database. METHODS: The National Cancer Database was queried for patients with UTUC who underwent extirpative surgery from 2004 to 2013. Predictors of receiving PC were identified using univariate and multivariate logistic regression. Temporal trends in the utilization of PC were also analyzed using a general analysis of variance linear model. RESULTS: From 2004 to 2013, there was significant increase in PC for UTUC from 9.6% to 13.8% (P = 0.0003). Neoadjuvant chemotherapy increased from 0.7% to 2.1% (P = 0.0018), whereas adjuvant chemotherapy remained relatively stable at 11.3%. Significant predictors of receiving PC on multivariate analysis were private insurance, ureter as the primary site, poorly differentiated and undifferentiated grade, lymphovascular invasion, positive margins, clinical T3 or T4 disease, nodal metastasis, and reporting from an academic research program. Patients who were≥70 years old,>50 miles to treatment center, had tumor in the kidney, or had an increased Charlson-Deyo Score were significantly less likely to receive PC. CONCLUSIONS: Over the time period studied, there has been an increase in the use of PC, primarily from increased administration of neoadjuvant chemotherapy. Its use is mostly associated with advanced pathologic characteristics. The study also highlights key demographic and socioeconomic differences that can help identify barriers to receiving PC and aid in making improvements in delivery of health care to patients with UTUC.
