RESUMO
BACKGROUND: A large proportion of patients with foregut cancers do not receive guideline-concordant treatment (GCT). This study sought to understand underlying barriers to GCT through a root cause analysis approach. METHODS: A single-institution retrospective review of 498 patients with foregut (gastric, pancreatic, and hepatobiliary) adenocarcinoma from 2018 to 2022 was performed. Guideline-concordant treatment was defined based on National Comprehensive Cancer Network guidelines. The Ishikawa cause and effect model was used to establish main contributing factors to non-GCT. RESULTS: Overall, 34% did not receive GCT. Root causes of non-GCT included Patient, Physician, Institutional Environment and Broader System-related factors. In decreasing order of frequency, the following contributed to non-GCT: receipt of incomplete therapy (N = 28, 16.5%), deconditioning on chemotherapy (N = 26, 15.3%), delays in care because of patient resource constraints followed by loss to follow-up (N = 19, 11.2%), physician factors (N = 19, 11.2%), no documentation of treatment plan after referral to oncologic expertise (N = 19, 11.2%), loss to follow-up before oncology referral (N = 17, 10%), nonreferral to medical oncologic expertise (N = 16, 9.4%), nonreferral to surgical oncology in patients with resectable disease (N = 15, 8.8%), and complications preventing completion of treatment (N = 11, 6.5%). Non-GCT often was a function of multiple intersecting patient, physician, and institutional factors. CONCLUSIONS: A substantial percentage of patients with foregut cancer do not receive GCT. Solutions that may improve receipt of GCT include development of automated systems to improve patient follow-up; institutional prioritization of resources to enhance staffing; financial counseling and assistance programs; and development and integration of structured prehabilitation programs into cancer treatment pathways.

BACKGROUND: Receipt of guideline-concordant treatment (GCT) is associated with improved prognosis in foregut cancers. Studies show that patients living in areas of high neighborhood deprivation have worse healthcare outcomes; however, its effect on GCT in foregut cancers has not been evaluated. We studied the impact of the area deprivation index (ADI) as a barrier to GCT. STUDY DESIGN: A single-institution retrospective review of 498 foregut cancer patients (gastric, pancreatic, and hepatobiliary adenocarcinoma) from 2018 to 2022 was performed. GCT was defined based on National Comprehensive Cancer Network guidelines. ADI, a validated measure of neighborhood disadvantage was divided into terciles (low, medium, and high) with high ADI indicating the most disadvantage. RESULTS: Of 498 patients, 328 (66%) received GCT: 66%, 72%, and 59% in pancreatic, gastric, and hepatobiliary cancers, respectively. Median (interquartile range) time from symptoms to workup was 6 (3 to 13) weeks, from diagnosis to oncology appointment was 4 (1 to 10) weeks, and from oncology appointment to treatment was 4 (2 to 10) weeks. Forty-six percent were diagnosed in the emergency department. On multivariable analyses, age 75 years or older (odds ratio [OR] 0.39 [95% CI 0.18 to 0.87]), Black race (OR 0.52 [95% CI 0.31 to 0.86]), high ADI (OR 0.25 (95% CI 0.14 to 0.48]), 6 weeks or more from symptoms to workup (OR 0.44 [95% CI 0.27 to 0.73]), 4 weeks or more from diagnosis to oncology appointment (OR 0.76 [95% CI 0.46 to 0.93]), and 4 weeks or more from oncology appointment to treatment (OR 0.63 [95% CI 0.36 to 0.98]) were independently associated with nonreceipt of GCT. CONCLUSIONS: Residence in an area of high deprivation predicts nonreceipt of GCT. This is due to multiple individual- and system-level barriers. Identifying these barriers and developing effective interventions, including community outreach and collaboration, leveraging telehealth, and increasing oncologic expertise in underserved areas, may improve access to GCT.

Introduction: In two Korean and Italian studies, the adherence rate (AR) to ASSLD 2005 guidelines in the management of hepatocellular carcinoma (HCC) was 60%. In a US study, the AR to American Association for the Study of Liver Disease (AASLD) 2005 guidelines was 73.3%, 26.8%, 25.3%, and 58.8% for patients with Barcelona Clinic Liver Cancer (BCLC) Stage A, B, C, and D, respectively, and nonadherence to guidelines was associated with longer overall survival (OS) in patients with BCLC Stage D. Here, we explored the AR to AASLD 2018 guidelines and its impact on OS. Methods: Between 2017 and 2019, 148 unique treatment-naïve patients with HCC were identified. Patients were staged according to the BCLC staging system and their AR to AASLD 2018 guidelines was noted. OS was estimated using Kaplan-Meier method. Survivals among patients from different groups was compared using Log-rank test. Results: The overall AR to AASLD 2018 guidelines was 83%. The AR for BCLC Stages 0, A, B, C, and D were 100%, 97%, 77%, 77%, and 38%, respectively. In patients with BCLC Stage D, the OS of patients treated with modalities adherent versus nonadherent to AASLD 2018 guidelines was 0.03 vs. 5.2 months (P = 0.0005). Otherwise, adherence versus nonadherence to AASLD 2018 guidelines showed no statistically significant differences in OS for patients with BCLC Stages 0, A, B, and C. Conclusion: The overall AR to AASLD 2018 guidelines was 83%. Nonadherence to AASLD 2018 guidelines in patients with BCLC Stage D translated into better OS.

BACKGROUND: Pancreatic adenocarcinoma (PDAC) is an aggressive malignancy associated with poor outcomes. Surgical resection and receipt of multimodal therapy have been shown to improve outcomes in patients with potentially resectable PDAC; however treatment and outcome disparities persist on many fronts. The aim of this study was to analyze the relationship between rural residence and receipt of quality cancer care in patients diagnosed with non-metastatic PDAC. METHODS: Using the National Cancer Database, patients with non-metastatic pancreatic cancer were identified from 2006-2016. Patients were classified as living in metropolitan, urban, or rural areas. Multivariable logistic regression was used to identify predictors of cancer treatment and survival. RESULTS: A total of 41,786 patients were identified: 81.6% metropolitan, 16.2% urban, and 2.2% rural. Rural residing patients were less likely to receive curative-intent surgery (p = 0.037) and multimodal therapy (p < 0.001) compared to their metropolitan and urban counterparts. On logistic regression analysis, rural residence was independently associated with decreased surgical resection [OR 0.82; CI 95% 0.69-0.99; p = 0.039] and multimodal therapy [OR 0.70; CI 95% 0.38-0.97; p = 0.047]. Rural residence independently predicted decreased overall survival [OR 1.64; CI 95% 1.45-1.93; p < 0.001] for all patients that were analyzed. In the cohort of patients who underwent surgical resection, rural residence did not independently predict overall survival [OR 0.97; CI 95% 0.85-1.11; p = 0.652]. CONCLUSIONS: Rural residence impacts receipt of optimal cancer care in patients with non-metastatic PDAC but does not predict overall survival in patients who receive curative-intent treatment.

BACKGROUND: The aim of this study was to evaluate the impact of medicaid expansion (ME) on receipt of palliative therapies in metastatic pancreatic cancer patients. PATIENTS AND METHODS: A difference-in-differences (DID) approach was used to analyze patients with metastatic pancreatic cancer identified from the National Cancer Database diagnosed during two time periods: pre-expansion (2010-2012) and post-expansion (2014-2016). Patients diagnosed while residing in ME states were compared with those in non-ME states. Multivariable logistic regression was used to identify predictors of receipt of palliative therapies. RESULTS: Of 87,738 patients overall, 7483(18.1%) received palliative therapies in the pre-expansion, while 10,211(21.5%) received palliative therapies in the post-expansion period. In the pre-expansion period, treatment at a high-volume facility (HVF) (odds ratio [OR] 1.10, 95% confidence interval [CI] 1.02-1.18) and non-west geographic location were predictive of increased palliative therapies. In the post-expansion period, treatment at an HVF (OR 1.09, 95% CI 1.02-1.16), geographic location, and living in an ME state at the time of diagnosis (OR 1.14, 95% CI 1.06-1.22) were predictive of increased palliative therapies. Older age, highest quartile median income (zip-code based), and treatment at a nonacademic facility were independently associated with decreased palliative therapies in both periods. DID analysis demonstrated that patients with metastatic pancreatic cancer living in ME states had increased receipt of palliative therapies relative to those in non-ME states (DID = 2.68, p < 0.001). CONCLUSIONS: The overall utilization of palliative therapies in metastatic pancreatic cancer is low. Multiple sociodemographic disparities exist in the receipt of palliative therapies. ME is associated with increased receipt of palliative therapies in patients with metastatic pancreatic cancer.

BACKGROUND: The impact of fragmentation of care (FC), i.e., receipt of care at > 1 institution, on treatment of pancreatic cancer is unknown. The purpose of this study was to determine factors associated with FC in curative-intent treatment of pancreatic cancer (PDAC) patients and evaluate how FC affects survival outcomes. METHODS: Using the National Cancer Database (NCDB), data on stage I-III PDAC patients diagnosed 2006-2016 were extracted. Multiple logistic regression analyses were performed to identify factors predictive of FC and survival. RESULTS: Of the 20,013 patients identified, 24.1% had FC. Factors predictive of FC were stage-III tumors (odds ratio [OR] 1.36; p = 0.014), higher median-income [third quartile (OR 1.38; p = 0.006) and highest-quartile (OR 1.50; p = 0.003)], care at high-volume facility (OR 1.47; p < 0.001), and receipt of multi-modal therapy (OR 1.69; p < 0.001). In contrast, age > 80 years (OR 0.82; p = 0.018), Black (OR 0.85; p = 0.013) or Asian race (OR 0.76; p = 0.033), Charlson comorbidity-index 2 (OR 0.85; p = 0.033), treatment at non-academic facility (OR 0.87; p = 0.041), and non-private insurance were negatively predictive of FC. FC independently predicted decreased 30-day [OR 0.57; p < 0.001] and 90-day mortality [OR 0.61; p < 0.001] and improved overall survival [hazard ratio 0.91; p < 0.001]. DISCUSSION: Sociodemographic factors are significantly associated with FC in curative-intent treatment of PDAC patients. FC was found to predict improved 30-day, 90-day, and overall survival outcomes.

BACKGROUND: Pancreatic cancer care is complex, and multiple disparities in receipt of therapies have been documented. The authors aimed to conduct a systematic review of the literature to critically assess and summarize disparities in access to oncologic therapies for pancreatic cancer. METHODS: A search of PubMed, Scopus, Web of Science, and Cochrane databases were performed for studies reporting disparities in access to oncologic care for pancreatic cancer. Primary research articles published in the United States from 2000 to 2020 were included. Data were independently extracted, and risk of bias was assessed using the modified Newcastle-Ottawa scale. RESULTS: The inclusion criteria were met by 47 studies. All the studies used retrospective data, with 70 % involving national database studies, 41 assessing the impact of race/ethnicity, 22 assessing the impact of socioeconomic status, 18 assessing the impact of insurance status, 23 assessing the impact of gender, 26 assessing the impact of age, and 3 assessing the impact of location on the delivery of cancer-directed therapies. Race, socioeconomic status, insurance status, gender, and age- based disparities in receipt of surgical resection, treatment at high-volume facilities and multimodal therapy for resectable pancreatic cancer, receipt of systemic chemotherapy for metastatic cancer, and receipt of expected standard-of-care treatment are reported. CONCLUSION: Significant sociodemographic disparities in access to equitable oncologic care exist along the continuum of pancreatic cancer care. Multiple patient, provider, and systemic factors contribute to these disparities. The ongoing study of these disparities is important to elucidate processes that may be targeted to improve access to equitable oncologic care for patients with pancreatic cancer.

BACKGROUND: Metastatic disease is the leading cause of mortality in colorectal cancer. Resection of colorectal liver metastases, when possible, is associated with improved long-term survival and the possibility of cure. However, nationwide studies suggest that liver resection is under-utilized in the treatment of colorectal liver metastases. This study was undertaken to understand attitudes and practice patterns among medical oncologists in the Deep South. METHODS: A survey of medical oncologists in the states of Alabama, Mississippi, and the Florida panhandle was performed. Respondents were queried regarding perceptions of resectability and attitudes towards surgical referral. RESULTS: We received 63 responses (32% response rate). Fifty percent of respondents reported no liver surgeons in their practice area. Commonly perceived contraindications to liver resection included extrahepatic metastatic disease (72%), presence of > 4 metastases (72%), bilobar metastases (61%), and metastases > 5 cm (46%). Bilobar metastatic disease was perceived as a contraindication more frequently by non-academic medical oncologists (70% vs. 33%, p = 0.03). CONCLUSIONS: Wide variations exist in perceptions of resectability and referral patterns for colorectal liver metastases among surveyed medical oncologists. There is a need for wider dissemination of resectability criteria and more liver surgeon involvement in the management of patients with colorectal liver metastases.

BACKGROUND: Socioeconomic- and demographic-based disparities exist in the treatment of pancreatic adenocarcinoma (PDAC). Medicaid expansion (ME) may have an impact on these disparities. Analyses of patients with PDAC from the National Cancer Database (NCDB) were performed to examine the impact of ME on access to treatment and outcomes. METHODS: Patients with non-metastatic PDAC diagnosed between 2006 and 2016 were identified. Multiple logistic regression analyses were performed to evaluate factors associated with curative-intent surgical resection, multimodal therapy, treatment at a high-volume facility (HVF), and survival. RESULTS: The study identified 41,876 patients who met the criteria. Medicaid expansion was independently associated with curative-intent resection (odds ratio [OR] 1.54; 95 % confidence interval [CI] 1.43-1.67; p < 0.001). In a multivariable analysis, ME was independently associated with multimodal therapy (OR 1.60; 95 % CI 1.44-1.76; p < 0.001) and treatment at an HVF (OR 1.57; 95 % CI 1.42-1.74; p < 0.001). Medicaid expansion was independently associated with improved 30-day mortality (OR 0.49; 95 % CI 0.34-0.79) and 90-day mortality (OR 0.48 95 % CI 0.35-0.59). Cox regression analysis demonstrated that after adjustment for other variables, ME status was associated with improved overall survival (hazard ratio [HR], 0.82; 95 % CI 0.73-0.90; p < 0.001). CONCLUSIONS: Medicaid expansion is associated with increased use of care processes that improve outcomes in PDAC, operative outcomes, and overall survival. The study data suggest that ME has helped to improve disparities in PDAC in ME states.

Patients with well-differentiated liposarcomas (WDLPS) of the extremity and trunk are treated primarily with surgical resection, with radiation used for a number of anecdotal reasons, including large size and positive margins. In this study, we evaluate the appropriate role for radiation in these tumors. A retrospective chart review of patients with extremity and trunk soft tissue liposarcomas referred to a free-standing cancer center from January 1995 to December 2011 was performed. One hundred eighty-three patients with extremity and trunk soft tissue WDLPS were identified: 61 per cent were female, median age was 60 years (range, 19-84 years) and 2 per cent had a focal area of dedifferentiation, margin status was positive in 57 per cent. Fourteen per cent of patients received radiation. Fifty patients developed recurrent disease; 28 per cent of these received radiation. Median time to recurrence was 18 years (range, 0.7-22 years). Of the 50 patients who recurred, 14 (28%) received radiation. Radiation was associated with decreased second recurrence when administered for recurrent disease (P = 0.03). On multivariable analysis, tumor size ≤ 10 cm (P = 0.014) and anatomically difficult area of resection (P = 0.008) were predictive of increased risk of recurrence. Older age (P = 0.02), dedifferentiated liposarcomas (P < 0.001), and difficult area of resection (P = 0.02) were associated with the administration of radiotherapy. Administration of radiation therapy was not associated with decreased time to recurrence in WDLPS overall; however, it should be considered in patients with recurrent disease.

BACKGROUND: Significant overtreatment of intraductal papillary mucinous neoplasms can be attributed to low specificity of the current International Consensus Guidelines as well as nonconformity with the guidelines. We compare the ability of the 2012 and revised 2017 intraductal papillary mucinous neoplasms International Consensus Guidelines to predict high-grade dysplasia/invasive cancer and to determine the preoperative variables that predict resection of benign or low-grade dysplasia in tertiary care centers. METHODS: Clinical, radiographic, and pathologic data for resected intraductal papillary mucinous neoplasms at 3 high-volume National Cancer Institute Cancer Centers were reviewed and the 2012 and 2017 consensus criteria were retrospectively applied. When International Consensus Guidelines were not met, clinical decision analysis was used to determine the primary indication for resection. Logistic regression identified variables associated with pathologic grade. RESULTS: Records for a total of 251 patients were reviewed, 129 of whom (52%) had low-grade dysplasia. The revised 2017 International Consensus Guidelines had high sensitivity (98.4%) and negative predicted value (96.1%), and all high-risk stigmata predicted high-grade dysplasia/invasive cancer; however, specificity remained low (14.8%). Nonconformity with International Consensus Guidelines was the most powerful predictor of low-grade dysplasia on final pathologic examination (9.5; 2.12-40.78). Independent predictors of low-grade dysplasia included age younger than 50 (2.46; 1.08-5.62), fine-needle aspiration without epithelial cells (2.6; 1.43-4.72), and normal duct diameter (3.07; 1.99-4.75). Diabetes developed in 30% of patients after resection. CONCLUSION: Management of intraductal papillary mucinous neoplasms remains clinically challenging. Low specificity of the International Consensus Guidelines and nonconformity with the guidelines continue to contribute to unnecessary pancreatic resections. Improved tools for disease classification as well as a better understanding of the natural history, biology, and rates of progression of intraductal papillary mucinous neoplasms are needed to avoid surgical overtreatment of low-grade intraductal papillary mucinous neoplasms.

The incidence of intraductal papillary mucinous neoplasms (IPMNs) has been increasing over the past decade, mainly owing to increased awareness and the increased use of cross-sectional imaging. The Sendai and Fukuoka consensus guidelines provide us with clinical management guidelines and algorithms; however, the clinical management of IPMNs continues to be challenging. Our incomplete understanding of the natural history of the disease, and the events and pathways that permit progression to adenocarcinoma, result in difficulties predicting which tumors are high risk and will progress to invasive disease. In this review, we summarize the current management guidelines and describe ongoing efforts to more clearly stratify IPMNs by risk of malignancy and identify IPMNs with malignant potential or ongoing malignant transformation.
