RESUMEN

Importance: Hospital networks formed around top-ranked cancer hospitals represent an opportunity to optimize complex cancer care in the community. Objective: To compare the short- and long-term survival after complex cancer treatment at top-ranked cancer hospitals and the affiliates of top-ranked hospitals. Design, Setting, and Participants: This cohort study was conducted using data from the unabridged version of the National Cancer Database. Included patients were individuals 18 years or older who underwent surgical treatment for esophageal, gastric, lung, pancreatic, colorectal, or bladder cancer diagnosed between January 1, 2012, and December 31, 2016. Patient outcomes after complex surgical procedures for cancer at top-ranked cancer hospitals (as ranked in top 50 by US News and World Report) were compared with outcomes at affiliates of top-ranked cancer hospitals (affiliation listed in American Hospitals Association survey and confirmed by search of internet presence). Data were analyzed from July through December 2019. Exposures: Undergoing complex cancer treatment at a top-ranked cancer hospital or an affiliated hospital. Main Outcomes and Measures: The association of affiliate status with short-term survival (ie, 90-day mortality) was compared using logistic regression, and the association of affiliate status with long-term survival was compared using time-to-event models, adjusting for patient demographic, payer, clinical, and treatment factors. Results: Among 119 834 patients who underwent surgical treatment for cancer, 79 981 patients (66.7%) were treated at top-ranked cancer hospitals (median [interquartile range] age, 66 [58-74] years; 40 910 [54.9%] men) and 39 853 patients (33.3%) were treated at affiliate hospitals (median [interquartile range] age, 69 [60-77] years; 19 004 [50.0%] men). In a pooled analysis of all cancer types, adjusted perioperative mortality within 90 days of surgical treatment was higher at affiliate hospitals compared with top-ranked hospitals (odds ratio, 1.67 [95% CI, 1.49-1.89]; P < .001). Adjusted long-term survival following cancer treatment at affiliate hospitals was only 77% that of top-ranked hospitals (time ratio, 0.77 [95% CI, 0.72-0.83]; P < .001). The survival advantage was not fully explained by differences in annual surgical volume, with both long- and short-term survival remaining superior at top-ranked hospitals even after models were adjusted for volume. Conclusions and Relevance: These findings suggest that short- and long-term survival after complex cancer treatment were superior at top-ranked hospitals compared with affiliates of top-ranked hospitals. Further study of cancer care within top-ranked cancer networks could reveal collaborative opportunities to improve survival across a broad contingent of the US population.

RESUMEN

BACKGROUND: Regionalization to higher volume centers has been proposed as a mechanism to improve short-term outcomes following complex surgery. OBJECTIVE: The objective of this study was to assess trends in regionalization and mortality for patients undergoing radical cystectomy (RC). RESEARCH DESIGN: An observational study of patients receiving RC in the United States from 2004 to 2013. SUBJECTS: Data for patients receiving RC were extracted from the National Cancer Database. MEASURES: The primary exposure was hospital volume; low-volume hospitals (LVH) included those with <5 RC/year and high-volume hospitals (HVH) were those with ≥30 RC/year. Trends in the volume were assessed, as were 30- and 90-day mortality. Cochrane-Armitage tests were performed for volume, and propensity score-weighted proportional hazard regression was used to assess mortality. RESULTS: A total of 47,028 RC were performed in 1162 hospitals from 2004 to 2013. The proportion of RC at LVH declined from 29% to 17% (P<0.01), whereas that of HVH increased from 16% to 33% (P<0.01). Unadjusted 30- (P=0.02) and 90-day (P<0.001) mortality decreased, and the absolute decrease was greatest at LVH (4.8% vs. 2.6%, P=0.03), whereas rates for HVH remained stable (1.9% vs. 1.4%, P=0.34). Following risk-adjustment, relative to treatment at HVH, treatment at LVH was associated with increased 30-day (hazard ratio: 1.66, 95% CI: 1.53-1.80) and 90-day mortality (hazard ratio: 1.37, 95% confidence interval: 1.30-1.44). CONCLUSIONS: Regionalization of RC to HVH was observed from 2004 to 2013. Treatment at LVH was associated with 66% and 33% relative increases in hazard of death at 30 and 90 days, respectively. These findings support the selective referral of complex cases to higher volume centers.

RESUMEN

BACKGROUND: Many quality measures in cancer care are process measures. The rates of compliance for these measures over time have not been well described, and the relationships between measure compliance and survival are not well understood. METHODS: The National Cancer Database, representing cancer registry data from approximately 1500 Commission on Cancer (CoC) cancer programs, was queried to determine the rates of compliance, with the CoC's colon cancer quality measure requiring 12 regional lymph nodes be removed at resection. Data were assessed in 2003, before the measure was reported to programs, through 2015. Measure compliance and risk-adjusted survival were examined by hospital type. RESULTS: From 2003 to 2015, 544,018 cases of colon cancer were analyzed for number of nodes removed. In 2003, compliance was 52.8% and National Cancer Institute (NCI) centers had the highest compliance rate (69.0%), followed by academic cancer centers (61.9%), comprehensive community hospitals (50.9%), and community hospitals (44.0%). Between 2003 and 2015, compliance improved for all hospital types, although differences remained. Risk-adjusted survival in 2009 was better at NCI centers [hazard ratio (HR) 0.76] than at academic cancer centers (HR 0.90), which had better survivals than comprehensive community programs (HR 0.93) when compared with patients treated at community hospitals. CONCLUSION: After introduction of this quality measure, performance at CoC-accredited hospitals improved over the subsequent 13 years, and survival by hospital type paralleled measure compliance by hospital type. This demonstrated measurement may be associated with improvements in performance, and that there are differences in performance and outcome by hospital type.

RESUMEN

BACKGROUND: The National Cancer Database (NCDB) is a hospital-based cancer registry that includes diagnostic, staging, treatment, and outcomes data for newly diagnosed cancer patients in the United States. The NCDB data include 31 million records for patients diagnosed between 1985-2015. A Participant User File based on a subset of these data has been available to researchers at facilities accredited by the Commission on Cancer since 2010. This study aimed to compare the number of incident cancer cases in the NCDB with a national population cancer registry. METHODS: Incident cancer cases in the NCDB in 2012-2014 were compared with the number of cancer cases in the United States Cancer Statistics data for the 2012-2014 diagnosis years. Comparisons were made by primary site and other factors. RESULTS: In 2012-2014, the NCDB captured 72% of the cancer cases in the United States, which was slightly higher than the 67% and 69% reported respectively in two prior assessments. Among the top 10 major cancer sites, the highest coverage (80%) was found for breast cancer, and the lowest was found for melanoma of the skin (52%) and prostate (58%). Colon, bladder, and kidney and renal pelvis cancers had relatively high coverage of 71%, 70% and 78%, respectively, whereas lung and bronchus had slightly lower coverage (65%). CONCLUSIONS: The NCDB coverage of U.S. cancer cases has remained relatively high (72%), but differences remain by cancer site and other factors that should be taken into account by users of the NCDB data.

RESUMEN

BACKGROUND: The current study was conducted to assess the impact of lymphovascular invasion on the survival of patients with urothelial carcinoma of the renal pelvis. METHODS: Patients with urothelial carcinoma of the renal pelvis who underwent radical nephroureterectomy from 2010 through 2015 were identified in the National Cancer Data Base. Patients were characterized according to demographic and clinical factors, including pathologic tumor stage and lymphovascular invasion. Associations with overall survival were assessed through proportional hazards regression analysis. RESULTS: A total of 4177 patients were identified; 1576 had lymphovascular invasion. Patients with T3 disease and lymphovascular invasion had 5-year survival that was significantly worse than that of patients with T3 disease without lymphovascular invasion (34.7% vs 52.6; P < .001 by the log-rank test), and approached that of patients with T4 disease without lymphovascular invasion (34.7% vs 26.5%; P = .002). On multivariate analysis controlling for age, comorbidities, grade, lymph node status, surgical margin status, race, sex, and chemotherapy administration, patients with T3 disease and lymphovascular invasion also were found to have significantly worse survival compared with patients with T3 disease without lymphovascular invasion (hazard ratio, 1.7; 95% confidence interval, 1.4-1.91). CONCLUSIONS: Lymphovascular invasion status is a key prognostic marker that can stratify the risk of patients with pT3 upper tract urothelial carcinoma further. Patients with this pathologic feature should be carefully considered for clinical trials exploring existing and novel therapies. Cancer 2018;124:2507-14. © 2018 American Cancer Society.

RESUMEN

PURPOSE: Prostate specific antigen based screening for prostate cancer has had a significant impact on the epidemiology of the disease. Its use has been associated with a significant decrease in prostate cancer mortality but has also resulted in the over diagnosis and overtreatment of indolent prostate cancer, exposing many men to the harms of treatment without benefit. The USPSTF (U.S. Preventive Services Task Force) in 2008 issued a recommendation against screening men older than 75 years, and in 2012 against routine screening for all men, indicating that in its interpretation the harms of screening outweigh the benefits. We review changes in the use of prostate specific antigen testing, performance of prostate biopsy, incidence of prostate cancer and stage of disease at presentation since 2012. MATERIALS AND METHODS: An English language literature search was performed for terms that included "prostate specific antigen," "screening" and "United States Preventive Services Task Force" in various combinations. A total of 26 original studies had been published on the effects of the USPSTF recommendations on prostate specific antigen based screening or prostate cancer incidence in the United States as of December 1, 2016. RESULTS: Review of the literature from 2012 through the end of 2016 indicates that there has been a decrease in prostate specific antigen testing and prostate biopsy. As a result, there has been a decline in the incidence of localized prostate cancer, including low, intermediate and high risk disease. The data regarding stage at presentation have yet to mature but there are some early signs of a shift toward higher burden of disease at presentation. CONCLUSIONS: These findings raise concern about a reversal of the observed improvement in prostate cancer specific mortality during preceding decades. Alternative screening strategies would 1) incorporate patient preferences by allowing shared decision-making, 2) preserve the survival benefits associated with screening, 3) improve the specificity of screening to reduce unnecessary biopsies and detection of low risk disease, and 4) promote the use of active surveillance for low risk cancers if they are detected.

RESUMEN

OBJECTIVES: To assess the relationship between surgeon (SV) and hospital volume (HV) on mortality after radical cystectomy (RC). PATIENTS AND METHODS: We queried the National Cancer Database (NCDB) for adult patients undergoing RC between 2010 and 2013. We calculated average volume for each surgeon and hospital. Using propensity-scored weights for combined volume groups with a proportional hazards regression model, we compared the associations between HV and SV with 90-day survival after RC. RESULTS: A total of 19 346 RCs were performed at 927 hospitals by 2 927 surgeons in the period 2010-2013. The median (interquartile range) HV and SV were 12.3 (5.0-35.5) and 4.3 (1.3-12.3) cases, respectively. For HV, 90-day unadjusted mortality was 8.5% in centres with <5 cases/year (95% confidence interval [CI] 7.7-9.3) and 5.6% in those with >30 cases/year (95% CI 5.0-6.2). For SV, 90-day mortality was 8.1% for surgeons with <5 cases/year (95% CI 7.6-8.6) and 4.0% for those with >30 cases/year (95% CI 2.8-5.2; all P < 0.05). The 30-day mortality rate was lowest for the combined HV-SV groups with HV >30, ranging from 1.6% to 2.1%. CONCLUSIONS: In hospitals reporting to the NCDB, volume was associated with improved mortality after RC. These associations appear to be driven by hospital- rather than surgeon-level effects. An elevated SV had a beneficial effect on mortality at the highest-volume hospitals. These findings inform efforts to regionalize complex surgical care and improve quality at community and safety net hospitals.

RESUMEN

Importance: The National Cancer Database (NCDB), a joint quality improvement initiative of the American College of Surgeons Commission on Cancer and the American Cancer Society, has created a shared research file that has changed the study of cancer care in the United States. A thorough understanding of the nuances, strengths, and limitations of the database by both readers and investigators is of critical importance. This review describes the use of the NCDB to study cancer care, with a focus on the advantages of using the database and important considerations that affect the interpretation of NCDB studies. Observations: The NCDB is one of the largest cancer registries in the world and has rapidly become one of the most commonly used data resources to study the care of cancer in the United States. The NCDB paints a comprehensive picture of cancer care, including a number of less commonly available details that enable subtle nuances of treatment to be studied. On the other hand, several potentially important patient and treatment attributes are not collected in the NCDB, which may affect the extent to which comparisons can be adjusted. Finally, the NCDB has undergone several significant changes during the past decade that may affect its completeness and the types of available data. Conclusions and Relevance: The NCDB offers a critically important perspective on cancer care in the United States. To capitalize on its strengths and adjust for its limitations, investigators and their audiences should familiarize themselves with the advantages and shortcomings of the NCDB, as well as its evolution over time.

RESUMEN

BACKGROUND: Although strong volume-outcome relationships exist for many cancer operations, patients continue to undergo these operations at low-volume hospitals. METHODS: Patients were identified from the National Cancer Data Base from 2010-2013 who underwent resection for bladder, breast, esophagus, lung, pancreas, rectum, and stomach cancers. Low-volume hospitals were defined as those in the bottom quartile by surgical volume for each cancer type separately. Logistic regression models were constructed to assess patient-level factors associated with undergoing cancer surgery at low-volume hospitals across cancer types while controlling for tumor characteristics. Survival outcomes (30- and 90-day mortality; overall survival) were also assessed. RESULTS: Low volume thresholds were 4, 84, 4, 18, 8, 7, and 4 resections per year for bladder, breast, esophagus, lung, pancreas, rectum, and stomach cancers, respectively, resulting in 772 (74.1%), 828 (57.5%), 664 (77.5%), 830 (64.7%), 716 (79.2%), 898 (65.1%), and 888 (68.5%) hospitals classified as low-volume hospitals, respectively. For all the cancers examined, patients were more likely to undergo operation at low-volume hospitals if they traveled shorter distances (home to surgical facility), resided in rural locations, or had not received neoadjuvant therapy. Other patient and tumor factors were not associated consistently with undergoing operation at low-volume hospitals. Patients who went to low-volume hospitals had poorer outcomes among the studied cancers. CONCLUSION: Patients continue to undergo operation at low-volume hospitals due to where they live and how far they have to travel. Regionalization policy initiatives will remain challenging in this population. Efforts should therefore continue to emphasize quality improvement locally at each facility caring for patients with cancer.

RESUMEN

PURPOSE: In October 2011 the USPSTF (U.S. Preventive Services Task Force) issued a draft guideline discouraging prostate specific antigen based screening for prostate cancer (grade D recommendation). We evaluated the effect of the USPSTF guideline on the number and distribution of new prostate cancer diagnoses in the United States. MATERIALS AND METHODS: We identified incident cancers diagnosed between January 2010 and December 2012 in NCDB (National Cancer Database). We performed an interrupted time series to evaluate the trend of new prostate cancers diagnosed each month before and after the draft guideline with colon cancer as a comparator. RESULTS: Incident monthly prostate cancer diagnoses decreased by -1,363 cases (12.2%, p<0.01) in the month after the USPSTF draft guideline and continued to decrease by 164 cases per month relative to baseline (-1.8%, p<0.01). In contrast monthly colon cancer diagnoses remained stable. Diagnoses of low, intermediate and high risk prostate cancers decreased significantly but new diagnoses of nonlocalized disease did not change. Subgroups of age, comorbidity, race, income and insurance showed comparable decreases in incident prostate cancer following the draft guideline. CONCLUSIONS: There was a 28% decrease in incident diagnoses of prostate cancer in the year after the USPSTF draft recommendation against prostate specific antigen screening. This study helps quantify the potential benefits (reduced harms of over diagnosis and overtreatment of low risk disease and disease found in elderly men) and potential harms (missed opportunities to diagnose important cancers in men who may benefit from treatment) of this guideline.

RESUMEN

BACKGROUND: Current American Joint Committee on Cancer/International Union against Cancer (AJCC/UICC) and European Network for the Study of Adrenal Tumors staging for adrenocortical carcinoma (ACC) have not shown a survival difference between patients with stage I/II disease. This study evaluates current staging systems for survival prediction using a larger cohort and assesses whether incorporating age into ACC staging improves survival predictions. METHODS: Patients in the National Cancer Data Base (1985-2006) with a diagnosis of ACC were identified and staged using a novel TNM-A staging system: Stage I (T1/T2N0M0, age ≤ 55), stage II (T1/T2N0M0, age >55), stage III (T1/T2N1M0 or T3/T4N0-N1M0, any age), or stage IV (any T any NM1, any age). Differences in overall survival (OS) by stage were compared using a Cox proportional hazards model. RESULTS: Staging was derived for 1,579 of 3,262 patients. Median age was 54 years; mean tumor size was 11.6 cm. Using current staging, differences in 5-year OS was observed only between patients with stages II/III and III/IV ACC. With TNM-A staging, differences in 5-year OS between all stages was significant (I/II [P < .003], II/III [P < .0001], III/IV [P < .0001]). CONCLUSION: A staging system that incorporates patient age better predicts 5-year OS among patients with stages I/II ACC. Consideration should be given to including age in staging for ACC, because it may better inform providers about treatment and prognosis.

RESUMEN

BACKGROUND: Operative mortality traditionally has been defined as the rate within 30 days or during the initial hospitalization, and studies that established the volume-outcome relationship for pancreatectomy used similar definitions. METHODS: Pancreatectomies reported to the National Cancer Data Base (NCDB) during 2007-2010 were examined for 30- and 90-day mortality. Unadjusted mortality rates were compared by type of resection, stage, comorbidities, and average annual hospital volume. Hierarchical logistic regression models generated risk-adjusted odds ratios for 30- and 90-day mortality. RESULTS: After 21,482 pancreatectomies, the unadjusted 30-day mortality rate was 3.7 % (95 % confidence interval [CI] 3.4-3.9 %), which doubled at 90 days to 7.4 % (95 % CI 7.0-7.8). The unadjusted and risk-adjusted mortality rates were higher at 30 days with increasing age, increasing stage, male gender, lower income, low hospital volume, resections other than distal pancreatectomy, Medicare or Medicaid insurance coverage, residence in a Southern census division, history of prior cancer, and multiple comorbidities. The lowest-volume hospitals (<5 per year) performed 19 % of the pancreatectomies, with a risk-adjusted odds ratios for mortality that were 4.2 times higher (95 % CI 3.1-5.8) at 30 days and remained 1.9 times higher (95 % CI 1.5-2.3) at 30-90 days compared with hospitals that had high volumes (≥40 per year). CONCLUSION: Mortality rates within 90 days after pancreatic resection are double those at 30 days. The volume-outcome relationship persists in the NCDB. Reporting mortality rates 90 days after pancreatectomy is important. Hospitals should be aware of their annual volume and mortality rates 30 and 90 days after pancreatectomy and should benchmark the use of high-volume hospitals.

RESUMEN

OBJECTIVE: To evaluate 30-day and 90-day mortality after major pulmonary resection for lung cancer including the relationship to hospital volume. METHODS: Major lung resections from 2007 to 2011 were identified in the National Cancer Data Base. Mortality was compared according to annual volume and demographic and clinical covariates using univariate and multivariable analyses, and included information on comorbidity. Statistical significance (P<.05) and 95% confidence intervals were assessed. RESULTS: There were 124,418 major pulmonary resections identified in 1233 facilities. The 30-day mortality rate was 2.8%. The 90-day mortality rate was 5.4%. Hospital volume was significantly associated with 30-day mortality, with a mortality rate of 3.7% for volumes less than 10, and 1.7% for volumes of 90 or more. Other variables significantly associated with 30-day mortality include older age, male sex, higher stage, pneumonectomy, a previous primary cancer, and multiple comorbidities. Similar results were found for 90-day mortality rates. In the multivariate analysis, hospital volume remained significant with adjusted odds ratios of 2.1 (95% confidence interval [CI], 1.7-2.6) for 30-day mortality and 1.3 (95% CI, 1.1-1.6) for conditional 90-day mortality for the hospitals with the lowest volume (<10) compared with those with the highest volume (>90). Hospitals with a volume less than 30 had an adjusted odds ratio for 30-day mortality of 1.3 (95% CI, 1.2-1.5) compared with those with a volume greater than 30. CONCLUSIONS: Mortality at 30 and 90 days and hospital volume should be monitored by institutions performing major pulmonary resection and benchmarked against hospitals performing at least 30 resections per year.

RESUMEN

OBJECTIVE: To examine the association of hospital volume and 90-day mortality after cystectomy, conditional on survival for 30 days. PATIENTS AND METHODS: The National Cancer Data Base was used to evaluate 30- and 90-day mortality for 35,055 patients who underwent cystectomy for bladder cancer at one of 1118 hospitals. Patient data were aggregated into hospital volume categories based on the mean annual number of procedures (low-volume hospital: <10 procedures; intermediate-volume hospital: 10-19 procedures; high-volume hospital: ≥20 procedures). Associations between mortality and clinical, demographic and hospital characteristics were analysed using hierarchical logistic regression models. To assess the association between hospital volume and 90-day mortality independently of shorter-term mortality, 90-day mortality conditional on 30-day survival was assessed in the multivariate modelling. RESULTS: Unadjusted 30- and 90-day mortality rates were 2.7 and 7.2% overall, 1.9 and 5.7% among high-volume hospitals, and 3.2 and 8.0% among low-volume hospitals, respectively. Compared with high-volume hospitals, the adjusted risks among low-volume hospitals (odds ratio [95% CI]) of 30- and 90-day mortality, conditional on having survived for 30 days, from the hierarchical models were 1.5 (1.3-1.9), and 1.2 (1.0-1.4), respectively. CONCLUSIONS: A low hospital volume was associated with greater 30- and 90-day mortality. These data support the need for further research to better understand the relatively high mortality rates seen between 30 and 90 days, which are high and less variable across hospital volume strata. The stronger association between volume and 30-day mortality suggests that quality-reporting efforts should focus on shorter-term outcomes.

RESUMEN

INTRODUCTION: To assess the impact of size at presentation in patients with adrenocortical carcinoma (ACC) on rates of synchronous metastatic disease and survival following resection using a large administrative dataset. MATERIALS AND METHODS: We queried the National Cancer Database (NCDB) dataset to assemble a cohort of patients with ACC based on SEER staging (1985-2000). Patients were stratified into three groups based on surgical tumor size cutoffs: < 4 cm, 4 cm-6 cm, and > 6 cm. Rates of metastatic disease at presentation in all ACC patients as well as relative survival for patients after resection of localized lesions were calculated and compared among groups. RESULTS: A total of 2248 patients had available staging information for analysis. Tumor size at presentation did not relate to likelihood of non-localized disease at presentation (p = 0.09). A restricted cubic splines analysis revealed a clinically insignificant relationship between tumor size and advanced disease at presentation (OR = 1.02 for each centimeter change in tumor size, p = 0.004, 95% CI 1.01-1.03). On multivariate analysis, only patient age (p < 0.01), and not tumor size, was a significant predictor of overall survival among patients undergoing resection of localized ACCs. CONCLUSIONS: Our data suggest that tumor size is imperfect in predicting presence of distant disease at presentation, nor does it consistently correlate with patient survival after resection of localized ACC.
