RESUMO

BACKGROUND: Medicaid expansion under the Affordable Care Act has improved access to screening and treatment for certain cancers. It is unclear how this policy has affected the diagnosis and management of pancreatic cancer. METHODS: Using a quasi-experimental difference-in-differences (DID) approach, we analyzed Medicaid and uninsured patients in the National Cancer Data Base during two time periods: pre-expansion (2011-2012) and postexpansion (2015-2016). We investigated changes in cancer staging, treatment decisions, and surgical outcomes. RESULTS: In this national cohort, pancreatic cancer patients in expansion states had increased Medicaid coverage relative to those in nonexpansion states (DID = 17.49, p < 0.01). Medicaid expansion also led to an increase in early-stage diagnoses (Stage I/II, DID = 4.71, p = 0.03), higher comorbidity scores among surgical patients (Charlson/Deyo score 0: DID = -13.69, p = 0.02), a trend toward more neoadjuvant radiation (DID = 6.15, p = 0.06), and more positive margins (DID = 11.69, p = 0.02). There were no differences in rates of surgery, postoperative outcomes, or overall survival. CONCLUSION: Medicaid expansion was associated with improved insurance coverage and earlier stage diagnoses for Medicaid and uninsured pancreatic cancer patients, but similar surgical outcomes and overall survival. These findings highlight both the benefits of Medicaid expansion and the potential limitations of policy change to improve outcomes for such an aggressive malignancy.

RESUMO

OBJECTIVES: The objective of this study was to create a composite measure, optimal oncologic surgery (OOS), for patients undergoing distal pancreatectomy for pancreatic adenocarcinoma and identify factors associated with OOS. METHODS: Adult patients undergoing distal pancreatectomy were identified from the National Cancer Database between 2010 and 2016. Patients were stratified based on receipt of OOS. Criteria for OOS included 90-day survival, no 30-day readmission, length of stay ≤7 days, negative resection margins, ≥12 lymph nodes harvested, and receipt of chemotherapy. Multivariate logistic regression was performed to identify predictors of OOS. Survival curves and a Cox proportional hazards model were created to compare survival and identify risk factors for mortality. RESULTS: Three thousand five hundred forty-six patients were identified. The rate of OOS was 22.3%. Diagnosis after 2012, treatment at an academic medical center, and a minimally invasive surgical approach (MIS) were associated with OOS. Survival was superior for patients undergoing OOS. Decreasing age at diagnosis, fewer comorbidities, surgery at an academic medical center, MIS, and lower pathologic stage were also associated with improved survival on multivariate analysis. CONCLUSIONS: Rates of OOS for distal pancreatectomy are low. Time trends show increasing rates of OOS that may be related to increasing MIS, adjuvant chemotherapy, and referrals to academic medical centers.

RESUMO

BACKGROUND: Safety-net hospitals serve a vital role in society by providing care for vulnerable populations. Existing data regarding oncologic outcomes of patients with colon cancer treated at safety-net hospitals are limited and variable. The objective of this study was to delineate disparities in treatment and outcomes for patients with colon cancer treated at safety-net hospitals. METHODS: This retrospective cohort study identified 802,304 adult patients with colon adenocarcinoma from the National Cancer Database between 2004-2016. Patients were stratified according to safety-net burden of the treating hospital as previously described. Patient, tumor, facility, and treatment characteristics were compared between groups as were operative and short-term outcomes. Cox proportional hazards regression was utilized to compare overall survival between patients treated at high, medium, and low burden hospitals. RESULTS: Patients treated at safety-net hospitals were demographically distinct and presented with more advanced disease. They were also less likely to receive surgery, adjuvant chemotherapy, negative resection margins, adequate lymphadenectomy, or a minimally invasive operative approach. On multivariate analysis adjusting for patient and tumor characteristics, survival was inferior for patients at safety-net hospitals, even for those with stage 0 (in situ) disease. CONCLUSION: This analysis revealed inferior survival for patients with colon cancer treated at safety-net hospitals, including those without invasive cancer. These findings suggest that unmeasured population differences may confound analyses and affect survival more than provider or treatment disparities.

RESUMO

Appendiceal neoplasms include a heterogeneous group of epithelial and nonepithelial tumors that exhibit varying malignant potential. This review article summarizes current diagnostic criteria, classification systems, and optimal therapeutic strategies for the five main histopathologic subtypes of appendiceal neoplasms. In particular, the management of epithelial appendiceal neoplasms has evolved. Although their treatment has historically been extrapolated from colon cancer, improved understanding of their unique histopathologic and molecular characteristics and a growing body of published clinical data support a more nuanced approach to their management.

RESUMO

BACKGROUND: Cytoreductive surgery and hyperthermic intraperitoneal chemoperfusion (CRS HIPEC) can offer significant survival advantage for select patients with colorectal peritoneal metastases (CRPM). Low socioeconomic status (SES) is implicated in disparities in access to care. We analyze the impact of SES on postoperative outcomes and survival at a high-volume tertiary CRS HIPEC center. PATIENTS AND METHODS: We conducted a retrospective cohort study examining patients who underwent CRS HIPEC for CRPM from 2000 to 2018. Patients were grouped according to SES. Baseline characteristics, perioperative outcomes, and survival were examined between groups. RESULTS: A total of 226 patients were analyzed, 107 (47%) low-SES and 119 (53%) high-SES patients. High-SES patients were younger (52 vs. 58 years, p = 0.01) and more likely to be White (95.0% vs. 91.6%, p = 0.06) and privately insured (83% vs. 57%, p < 0.001). They traveled significantly further for treatment and had lower burden of comorbidities and frailty (p = 0.01). Low-SES patients more often presented with synchronous peritoneal metastases (48% vs. 35%, p = 0.05). Following CRS HIPEC, low-SES patients had longer length of stay and higher burden of postoperative complications, 90-day readmission, and 30-day mortality. Median overall survival following CRS HIPEC was worse for low-SES patients (17.8 vs. 32.4 months, p = 0.02). This disparity persisted on multivariate survival analysis (low SES: HR = 1.46, p = 0.03). CONCLUSIONS: Despite improving therapies for CRPM, low-SES patients remain at a significant disadvantage. Even patients who overcome barriers to care experience worse short- and long-term outcomes. Improving access and addressing these disparities is crucial to ensure equitable outcomes and improve patient care.

RESUMO

BACKGROUND: Colorectal adenocarcinoma is a leading cause of cancer mortality worldwide, often requiring patients to undergo anatomy-altering surgical interventions leading to increased postoperative readmission. Hospital readmission rates have been correlated with increased mortality. Therefore, it is important to understand the association between 30-day readmission rates and mortality as well as the factors associated with increased readmission rates. STUDY DESIGN: This is a retrospective review utilizing data from the National Cancer Database. Our primary outcomes of interest were 30- and 90-day mortality rates. Our primary independent variable of interest was 30-day readmission. RESULTS: Between 2010 and 2016, 207 299 patients underwent surgery for rectal cancer and 754 895 for colon cancer. The readmission rates within 30 days of discharge were 5.4% and 5.5% for patients after surgery for rectal or colon cancer, respectively. 30-day readmission was not associated with 30-day mortality, but it was independently associated with increased 90-day mortality and inferior long-term survival for both cohorts (P = .001). Independent risk factors significantly associated with increased readmission included race, non-private insurance, and low income. CONCLUSION: This study provides a large, up-to-date, and comprehensive analysis of readmission rates for colon and rectal cancers. We demonstrate that socioeconomic factors are associated with increased 30-day readmission. 30-day readmission is also independently associated with increased 90-day mortality as well as lower overall survival rates. Our study supports the need for implementation of programs that support patients of lower socioeconomic status undergoing surgery to further decrease readmission rates and mortality.

RESUMO

AIMS: National studies have demonstrated disparities in the treatment and survival of pancreatic cancer patients based on socioeconomic status (SES). This study aimed to identify specific differences in perioperative management and outcomes based on patient SES and to study the role of a multidisciplinary clinic (MDC) in mitigating any variations. METHODS: The study analyzed patients undergoing pancreaticoduodenectomy for pancreatic ductal adenocarcinoma in a large hospital system. The patients were categorized into groups of high and low SES and whether they were managed by the authors' pancreatic cancer MDC or not. The study compared differences in disease characteristics, receipt of multimodality therapy, perioperative outcomes, and recurrence-free and overall survival. RESULTS: Of the 162 low-SES patients and 119 high-SES patients, 54% were managed in the MDC. Outside the MDC, low-SES patients were less likely to receive neoadjuvant chemotherapy and had less minimally invasive surgery, a longer OR time, less enhanced recovery participation, and more major complications (p < 0.05). No SES disparities were observed among the MDC patients. Despite similar tumor characteristics, the low-SES patients had inferior median overall survival (21 vs 32 months; p = 0.005), but the MDC appeared to eliminate this disparity. Low SES correlated with inferior survival for the non-MDC patients (17 vs 32 months; p < 0.001), but not for the MDC patients (24 vs 25 months; p = 0.33). These findings persisted in the multivariable analysis. CONCLUSION: A pancreatic cancer MDC standardizes treatment decisions, eliminates disparities in surgical outcomes, and improves survival for low-SES patients.

RESUMO

AIM: To assess the predictors and influence of resection margins and the role of neoadjuvant and adjuvant therapy on survival for a national cohort of patients with resected pancreatic cancer. METHODS: Using the National Cancer Data Base between 2004 and 2016, 56,532 patients were identified who underwent surgical resection for pancreatic adenocarcinoma. Univariate and multivariate models were employed to identify factors predicting R0/R1 resection and assess the impact on survival. RESULTS: In total, 48,367 (85.6%) patients were found to have negative margins (R0) compared to 8165 (14.4%) who had microscopic residual tumor (R1). Factors predicting positive margin on univariate analysis included male gender, Medicare, advanced stage, moderately or poorly differentiated tumor, lymphovascular invasion, and tumors > 2 cm. Factors predicting R0 resection included receipt of neoadjuvant therapy and treatment at an Academic/Research Center. Following adjustment for other factors, margin status remained an independent predictor for overall survival (HR: 1.24; 95% CI 1.22-1.27, p < 0.001) (1-, 3-, and 5-year overall survival rates (R0: 77%, 37%, and 25% vs R1: 62%, 19%, and 10%). CONCLUSIONS: A positive margin predicts a poorer survival than R0 resections regardless of stage and receipt of adjuvant therapy. Several modifiable factors significantly predict the likelihood of R0 resection including neoadjuvant treatment and treatment at Academic/Research Programs. Knowledge about these factors can help guide patient management by offering neoadjuvant treatment modalities at Academic as well as Community hospitals.

RESUMO

BACKGROUND: Chronic traumatic encephalopathy is a consequence of repetitive mild traumatic brain injury (rmTBI). These injuries can result in psychiatric disorders that are treated with amitriptyline. Amitriptyline improves neuronal regeneration in major depression via inhibition of acid sphingomyelinase. We hypothesized that acid sphingomyelinase inhibition would preserve neuronal regeneration and decrease depressive symptoms following rmTBI in a murine model. METHODS: A murine model of rmTBI was established using a weight-drop method. Mice were subjected to mTBI every other day for 7 d. Mice received amitriptyline injection 2 h prior to each mTBI. After the final mTBI, mice underwent behavioral studies or biochemical analysis. Hippocampi were analyzed for markers of neurogenesis and phosphorylated tau aggregation. RESULTS: Mice that underwent rmTBI showed increased hippocampal phosphorylated tau aggregation 1 mo following rmTBI as well as decreased neuronal regeneration by bromodeoxyuridine uptake and doublecortin immunohistochemistry. Mice with either genetic deficiency or pharmacologic inhibition of acid sphingomyelinase demonstrated improved neuronal regeneration and decreased phosphorylated tau aggregation compared to untreated rmTBI mice. Behavioral testing showed rmTBI mice spent significantly more time in the dark and waiting to initiate feeding compared to sham mice. These behaviors were partially prevented by the inhibition of acid sphingomyelinase. CONCLUSIONS: We established a murine model of rmTBI that leads to tauopathy, depression, and impaired hippocampal neurogenesis. Inhibition of acid sphingomyelinase prevented the harmful neurologic and behavioral effects of rmTBI. These findings highlight an important opportunity to improve recovery or prevent neuropsychiatric decline in patients at risk for chronic traumatic encephalopathy.

RESUMO

BACKGROUND: Robotic pancreatic surgery is expanding throughout centers across the country. We investigated national trends in the use and outcomes for robotic-assisted pancreaticoduodenectomy (RPD) and distal pancreatectomy (RDP) for primary pancreatic tumors. METHODS: The National Cancer Database was queried for RPD and RDP performed during three time periods: 2010-2012, 2013-2014, and 2015-2016. These time periods were compared for patient and center factors as well as surgical outcomes. RESULTS: The use of robotic surgery increased during the study period. Most centers performed a low volume of robotic surgery (RPD, 82% of centers averaged < 1 case/year; RDP, 87% averaged < 1 case/year). From the first to last time period, the proportion of cases performed at academic centers decreased (RPD, 83% to 56%; RDP, 77% to 58%, p < 0.001) while patient characteristics remained largely unchanged. For RPD, improvements in mortality (6.7 to 1.8%, p = 0.013) and lymphadenectomy (18 to 21 nodes, p = 0.035) were observed, with no changes in conversion to open surgery, negative margin resections, or readmissions. For RDP, length of stay decreased (7 to 6 days, p = 0.048), but there were no changes in other outcomes. Compared with academic centers, non-academic centers had equivalent rates of conversion to open surgery, negative margins, and 90-day mortality. On multivariate analysis, there was no difference in survival between academic and non-academic centers. DISCUSSION: Robotic pancreas surgery is expanding to a greater variety of centers nationwide with preservation of key surgical outcomes. These findings support the continued rigorous training and proliferation of qualified robotic pancreas surgeons going forward.

RESUMO

BACKGROUND: The Affordable Care Act facilitated improved insurance coverage for states that expanded Medicaid coverage, but the impact on cancer outcomes is unclear. This study compared changes in the diagnosis and management of colon cancer in states that did and did not participate in Medicaid expansion. STUDY DESIGN: Using a quasi-experimental difference-in-differences (DID) approach, we analyzed Medicaid and uninsured patients in the National Cancer Data Base during 2 time periods: pre (2011-2012) and post expansion (2015-2016). Patients in non-expansion states were compared with those in January 2014 expansion states with regard to changes in patient and facility characteristics, cancer staging, treatment decisions, and surgical outcomes. RESULTS: Along with increased Medicaid coverage (DID = 20.27; p < 0.001), patients in expansion states had an increase in stage I diagnoses (DID = 2.97; p = 0.035), distance traveled (miles, DID = 6.67; p = 0.005), and treatment at integrated network programs (DID = 2.67; p = 0.045). More early-stage patients were treated within 30 days (DID = 7.24; p = 0.035) and more stage IV patients received palliative care (DID = 5.01; p = 0.048). Among surgical patients, Medicaid expansion correlated with fewer urgent cases (< 7 days, DID = -5.88; p = 0.008) and more minimally invasive surgery (DID = 5.00; p = 0.022). There were no observed differences in postoperative outcomes or adjuvant chemotherapy. CONCLUSIONS: Medicaid expansion correlated with earlier diagnosis, enhanced access, and improved surgical care for colon cancer patients. These findings highlight the importance of improving health insurance coverage and can help guide future policy efforts.

RESUMO

BACKGROUND: Open extended cholecystectomy (O-EC) has long been the recommended treatment for resectable gallbladder cancer (GBC), while the minimally-invasive approach for EC (MIS-EC) remains controversial. Our aim was to analyze overall survival of GBC patients treated with MIS-EC vs O-EC at the national level. METHODS: A retrospective review of the National Cancer Database of patients with resectable GBC (2010-2016) and treated with either MIS-EC or O-EC was performed. Overall survival (OS) was compared by the surgical approach. RESULTS: A total of 680 patients were identified, of whom 235 (34.6%) underwent MIS-EC. There were no differences in the rates of positive margins between MIS-EC and O-EC (14% vs 19%, respectively; P = .278), and in the mean lymph node yield (6.54 vs 6.66, respectively; P = .914). The median survival following MIS-EC was significantly higher than that of O-EC (39 vs 26 months; P = .048). After stratification by pathological stage and after adjustment, there was no significant difference in OS between the groups (HR = 0.9, 95% CI, 0.6-1.5). CONCLUSION: In this large national cohort, MIS-EC oncologic outcomes were noninferior to the O-EC. Proficiency with MIS techniques, proper patient selection, and referral to specialized centers may allow a greater benefit from this treatment modality.

RESUMO

Acute lung injury is a major complication of hemorrhagic shock and the required resuscitation with large volumes of crystalloid fluids and blood products. We previously identified a role of macrophage-derived chemokine (CCL22/MDC) pulmonary inflammation following hemorrhage and resuscitation. However, further details regarding the induction of CCL22/MDC and its precise role in pulmonary inflammation after trauma remain unknown. In the current study we used in vitro experiments with a murine alveolar macrophage cell line, as well as an in vivo mouse model of hemorrhage and resuscitation, to identify key regulators in CCL22/MDC production. We show that trauma induces expression of IFNγ, which leads to production of CCL22/MDC through a signaling mechanism involving p38 MAPK, NF-κB, JAK, and STAT-1. IFNγ also activates TNFα production by alveolar macrophages, potentiating CCL22/MDC production via an autocrine mechanism. Neutralization of IFNγ or TNFα with specific antibodies reduced histological signs of pulmonary injury after hemorrhage and reduced inflammatory cell infiltration into the lungs.

RESUMO

BACKGROUND: Patients undergoing complex surgery at safety net hospitals have been shown to suffer inferior short-term outcomes. Liver transplantation, one of the most complex surgical interventions, is offered at certain safety net hospitals. We sought to identify whether patients undergoing liver transplantation at safety net hospitals have inferior outcomes compared with lower burden centers. METHODS: Using a link between the University HealthSystem Consortium and Scientific Registry of Transplant Recipient databases, we identified 11,047 patients undergoing liver transplantation at 63 centers between 2009 and 2012. Hospitals were grouped by safety net burden, defined as the proportion of Medicaid or uninsured patient encounters during that time. The highest quartile (safety net hospitals) was compared to medium- and low-burden hospitals regarding recipient and donor characteristics, perioperative outcomes, and long-term survival. RESULTS: Liver transplantation recipients at safety net hospitals were more often black and of lower socioeconomic status (P < .01), but had similar model for end-stage liver disease scores (20 vs 20 vs 18) compared with median-burden hospitals and low burden hospitals. Length of stay and readmission rates were similar; however, safety net hospitals demonstrated higher in-hospital mortality (5.2% vs 4.5% vs 2.9%, P < .01). Despite this, there was no significant difference in overall patient or graft survivals in patients who underwent liver transplantation at safety net hospitals and survived the perioperative setting at a median follow-up of 2 years (P > .05). CONCLUSION: Despite differences in perioperative outcomes at safety net hospitals, these centers achieve noninferior long-term patient and graft survival for potentially vulnerable patients requiring liver transplantation. Strict care standardization, as achieved in liver transplantation, may be a mechanism by which outcomes can be improved at safety net hospitals after other complex surgical procedures.
