RESUMEN

OBJECTIVE: To evaluate the relationship between partial nephrectomy (PN) and hospital availability of robot-assisted surgery from a population-based cohort in the USA. METHODS: After merging the Nationwide Inpatient Sample (NIS) and the American Hospital Association survey from 2006 to 2008, we identified 21 179 patients who underwent either PN or radical nephrectomy (RN) for renal cell carcinoma (RCC). The primary outcome assessed was the type of nephrectomy performed. Multivariable logistic regression identified the patient and hospital characteristics associated with receipt of PN. RESULTS: We identified 4832 (22.8%) and 16 347 (77.2%) patients who were treated for RCC with PN and RN, respectively. On multivariable analysis, patients were more likely to receive PN at academic centres (odds ratio [OR] 2.77; P < 0.001), urban centres (OR 3.66; P < 0.001) and American College of Surgeons (ACOS)-designated cancer centres (OR: 1.10; P < 0.05) compared with non-academic, rural and non-ACOS-designated cancer centre hospitals, respectively. Robot-assisted surgery availability at a hospital was also associated with a higher adjusted odds of PN compared with centres without that availability (OR 1.28; P < 0.001). CONCLUSIONS: Although academic and urban locations are established factors that affect the receipt of PN for RCC, the availability of robot-assisted surgery at a hospital was also independently associated with higher use of PN. Our results are informative in identifying other key hospital characteristics which may facilitate greater adoption of PN.

RESUMEN

OBJECTIVE: To obtain prospective outcomes data on patients (pts) undergoing palliative operative or endoscopic procedures for malignant bowel obstruction due to recurrent ovarian cancer. METHODS: An institutional study was conducted from July 2002 to July 2003 to prospectively identify pts who underwent an operative or endoscopic procedure to palliate the symptoms of advanced cancer. This report focuses on pts with malignant bowel obstruction due to recurrent ovarian cancer. Procedures performed with an upper or lower gastrointestinal (GI) endoscope were considered "endoscopic." All other cases were classified as "operative." Following the procedure, the presence or absence of symptoms was determined and followed over time. All pts were followed until death. RESULTS: Palliative interventions were performed on 74 gynecologic oncology pts during the study period, of which 26 (35%) were for malignant GI obstruction due to recurrent ovarian cancer. The site of obstruction was small bowel in 14 (54%) cases and large bowel in 12 (46%) cases. Palliative procedures were operative in 14 (54%) pts and endoscopic in the other 12 (46%). Overall, symptomatic improvement or resolution within 30 days was achieved in 23 (88%) of 26 patients, with 1 (4%) postprocedure mortality. At 60 days, 10 (71%) of 14 pts who underwent operative procedures and 6 (50%) of 12 pts who had endoscopic procedures had symptom control. Median survival from the time of the palliative procedure was 191 days (range, 33-902) for those undergoing an operative procedure and 78 days (range, 18-284) for those undergoing an endoscopic procedure. CONCLUSION: Patients with malignant bowel obstructions due to recurrent ovarian cancer have a high likelihood of experiencing relief of symptoms with palliative procedures. Although recurrence of symptoms is common, durable palliation and extended survival are possible, especially in those patients selected for operative intervention.

RESUMEN

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.
