Treatment strategies for borderline resectable pancreatic neuroendocrine tumors: a narrative review.

BACKGROUND AND OBJECTIVE: Well-differentiated pancreatic neuroendocrine tumors (pNETs) are a group of rare, heterogeneous tumors that originate in the endocrine tissue of the pancreas and account for 1-2% of all pancreatic neoplasms. The majority of pNETs are non-functional and typically follow a more indolent course. Especially at early stages, the primary management of pNETs is surgical resection which is associated with relatively low rates of recurrence and excellent long-term prognosis. On the other hand, some patients will present with locally advanced primary tumors or low volume metastatic disease in which complete surgical resection may be more difficult to achieve and recurrence rates are significant. Unlike treatment of borderline resectable (BR) pancreatic adenocarcinoma, in which neoadjuvant treatment strategies are becoming standardized, borderline resectability is not a currently established terminology for pNETs and the optimal multidisciplinary treatment approach is poorly understood. METHODS: We performed a literature search on PubMed, Google Scholar, and ClinicalTrials.gov using keywords, including 'pancreatic neuroendocrine tumor' and 'borderline resectable'. All studies and review articles in English with full text were considered. Each publication was independently reviewed. KEY CONTENT AND FINDINGS: We introduce the concept of BR-pNETs, focusing on important criteria that should be included in their definition by balancing the feasibility of resection and the clinical utility of surgery. We suggest that extended resection, involving vascular reconstruction, adjacent organ resection, and/or liver metastasis, should be considered at experienced, high volume centers. Furthermore, we outline multidisciplinary treatment strategies, including systemic and locoregional treatment options, for optimizing outcomes for this growing patient population. CONCLUSIONS: Formalizing the definition of resectability in pNETs through multidisciplinary collaborative research will be important for standardizing the indications for multimodality treatment and aggressive surgical approaches for patients.

Reporting time toxicity in prospective cancer clinical trials: A scoping review.

PURPOSE: This review aimed to assess the measurement and reporting of time toxicity (i.e., time spent receiving care) within prospective oncologic studies. METHODS: On July 23, 2023, PubMed, Scopus, and Embase were queried for prospective or randomized controlled trials (RCT) from 1984 to 2023 that reported time toxicity as a primary or secondary outcome for oncologic treatments or interventions. Secondary analyses of RCTs were included if they reported time toxicity. The included studies were then evaluated for how they reported and defined time toxicity. RESULTS: The initial query identified 883 records, with 10 studies (3 RCTs, 2 prospective cohort studies, and 5 secondary analyses of RCTs) meeting the final inclusion criteria. Treatment interventions included surgery (n = 5), systemic therapies (n = 4), and specialized palliative care (n = 1). The metric "days alive and out of the hospital" was used by 80% (n = 4) of the surgical studies. Three of the surgical studies did not include time spent receiving ambulatory care within the calculation of time toxicity. "Time spent at home" was assessed by three studies (30%), each using different definitions. The five secondary analyses from RCTs used more comprehensive metrics that included time spent receiving both inpatient and ambulatory care. CONCLUSIONS: Time toxicity is infrequently reported within oncologic clinical trials, with no standardized definition, metric, or methodology. Further research is needed to identify best practices in the measurement and reporting of time toxicity to develop strategies that can be implemented to reduce its burden on patients seeking cancer care.

Failure to Undergo Resection Following Neoadjuvant Therapy for Resectable Pancreatic Cancer: A Secondary Analysis of SWOG S1505.

BACKGROUND: Neoadjuvant therapy (NT) is increasingly used for patients with pancreatic ductal adenocarcinoma (PDAC), and yet reasons for not undergoing subsequent pancreatectomy are poorly understood. Given the importance of completing multimodality therapy, we investigated factors associated with failure to undergo surgical resection following NT for PDAC. METHODS: SWOG S1505 was a multicenter phase II randomized trial of preoperative mFOLFIRINOX or gemcitabine/nab-paclitaxel prior to planned pancreatectomy for patients with potentially resectable PDAC. Associations between clinical, demographic, and hospital-level characteristics and receipt of surgical resection were estimated via multiple logistic regression. Differences in overall survival from 18 weeks postrandomization (scheduled time of surgery) according to resection status were assessed via Cox regression models. RESULTS: Among 102 eligible patients, 73 (71.6%) underwent successful pancreatectomy, whereas 29 (28.4%) did not, primarily because of progression (n=11; 10.8%) or toxicity during NT (n=9; 8.8%). Weight loss during NT (odds ratio [OR], 0.34; 95% CI, 0.11-0.93) and the hospital's city size (small: OR, 0.24 [95% CI, 0.07-0.80] and large: OR, 0.28 [95% CI, 0.10-0.79] compared with midsize) were significantly associated with a lower probability of surgical resection in adjusted models, whereas age, sex, race, body mass index, performance status, insurance type, geographic region, treatment arm, tumor location, chemotherapy delays/modifications, and hospital characteristics were not. Surgical resection following NT was associated with improved overall survival (median, 23.8 vs 10.8 months; P<.01) even after adjusting for grade 3-5 adverse events during NT, performance status, and body mass index (hazard ratio, 0.55; 95% CI, 0.32-0.95). CONCLUSIONS: Failure to undergo resection following NT was relatively common among patients with potentially resectable PDAC and associated with worse survival. Although few predictive factors were identified in this secondary analysis of the SWOG S1505 randomized trial, further research must focus on risk factors for severe toxicities during NT that preclude surgical resection so that patient-centered interventions can be delivered or alternate treatment sequencing can be recommended.

Effect of Behavioral Health Disorders on Surgical Outcomes in Cancer Patients.

BACKGROUND: Behavioral health disorders (BHDs) can often be exacerbated in the setting of cancer. We sought to define the prevalence of BHD among cancer patients and characterize the association of BHD with surgical outcomes. STUDY DESIGN: Patients diagnosed with lung, esophageal, gastric, liver, pancreatic, and colorectal cancer between 2018 and 2021 were identified within Medicare Standard Analytic Files. Data on BHD defined as substance abuse, eating disorder, or sleep disorder were obtained. Postoperative textbook outcomes (ie no complications, prolonged length of stay, 90-day readmission, or 90-day mortality), as well as in-hospital expenditures and overall survival were assessed. RESULTS: Among 694,836 cancer patients, 46,719 (6.7%) patients had at least 1 BHD. Patients with BHD were less likely to undergo resection (no BHD: 23.4% vs BHD: 20.3%; p < 0.001). Among surgical patients, individuals with BHD had higher odds of a complication (odds ratio [OR] 1.32 [1.26 to 1.39]), prolonged length of stay (OR 1.36 [1.29 to 1.43]), and 90-day readmission (OR 1.57 [1.50 to 1.65]) independent of social vulnerability or hospital-volume status resulting in lower odds to achieve a TO (OR 0.66 [0.63 to 0.69]). Surgical patients with BHD also had higher in-hospital expenditures (no BHD: $16,159 vs BHD: $17,432; p < 0.001). Of note, patients with BHD had worse long-term postoperative survival (median, no BHD: 46.6 [45.9 to 46.7] vs BHD: 37.1 [35.6 to 38.7] months) even after controlling for other clinical factors (hazard ratio 1.26 [1.22 to 1.31], p < 0.001). CONCLUSIONS: BHD was associated with lower likelihood to achieve a postoperative textbook outcome, higher expenditures, as well as worse prognosis. Initiatives to target BHD are needed to improve outcomes of cancer patients undergoing surgery.

Recurrence following Resection of Intraductal Papillary Mucinous Neoplasms: A Systematic Review to Guide Surveillance.

Patients who undergo resection for non-invasive IPMN are at risk for long-term recurrence. Further evidence is needed to identify evidence-based surveillance strategies based on the risk of recurrence. We performed a systematic review of the current literature regarding recurrence patterns following resection of non-invasive IPMN to summarize evidence-based recommendations for surveillance. Among the 61 studies reviewed, a total of 8779 patients underwent resection for non-invasive IPMN. The pooled overall median follow-up time was 49.5 months (IQR: 38.5-57.7) and ranged between 14.1 months and 114 months. The overall median recurrence rate for patients with resected non-invasive IPMN was 8.8% (IQR: 5.0, 15.6) and ranged from 0% to 27.6%. Among the 33 studies reporting the time to recurrence, the overall median time to recurrence was 24 months (IQR: 17, 46). Existing literature on recurrence rates and post-resection surveillance strategies for patients with resected non-invasive IPMN varies greatly. Patients with resected non-invasive IPMN appear to be at risk for long-term recurrence and should undergo routine surveillance.

Preoperative CA 19-9 Predicts Disease Progression in Colorectal Peritoneal Metastases Treated with Cytoreductive Surgery and Hyperthermic Intraperitoneal Chemotherapy: An Analysis from the US HIPEC Collaborative.

INTRODUCTION: Patients with colorectal peritoneal metastases (CRPM) are increasingly treated with cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CRS/HIPEC). Unfortunately, data identifying preoperative risk factors for poor oncologic outcomes after this procedure are limited. We aimed to determine the prognostic value of preoperative CEA, CA 125, and CA 19-9 on disease progression after CRS/HIPEC. METHODS: Patients with CRPM treated with curative intent CRS/HIPEC from 12 participating sites in the United States from 2000 to 2017 were identified. Progression-free survival (PFS), defined as disease progression or recurrence, was the primary outcome. RESULTS: In 279 patients who met inclusion criteria, the rate of disease progression was 63.8%, with a median PFS of 11 months (interquartile range [IQR] 5-20). Elevated CA 19-9 was associated with dismal PFS at 2 years (8.9% elevated vs. 30% not elevated, p < 0.01). In 113 patients who underwent upfront CRS/HIPEC, CA 19-9 emerged as the sole tumor marker independently predictive of worse PFS (hazard ratio [HR] 2.88, p = 0.048). In the subgroup of patients who had received neoadjuvant therapy (NAT), no variable was independently predictive of PFS. CA 19-9 levels over 37 U/ml were highly specific for accelerated disease progression after CRS/HIPEC. Lastly, there was no association between PFS and elevated CEA or CA 125. CONCLUSIONS: Elevated CA 19-9 is associated with decreased PFS in patients with CRPM. While traditionally CEA is the main tumor marker assessed in colon cancer, we found that CA 19-9 may better inform preoperative risk stratification for poor oncologic outcomes in patients with CRPM. However, prospective studies are required to confirm this association.

Consideration of Metastasis-Directed Therapy for Patients With Metastatic Colorectal Cancer: Expert Survey and Systematic Review.

BACKGROUND: A survey of medical oncologists (MOs), radiation oncologists (ROs), and surgical oncologists (SOs) who are experts in the management of patients with metastatic colorectal cancer (mCRC) was conducted to identify factors used to consider metastasis-directed therapy (MDT). MATERIALS AND METHODS: An online survey to assess clinical factors when weighing MDT in patients with mCRC was developed based on systematic review of the literature and integrated with clinical vignettes. Supporting evidence from the systematic review was included to aid in answering questions. RESULTS: Among 75 experts on mCRC invited, 47 (response rate 62.7%) chose to participate including 16 MOs, 16 ROs, and 15 SOs. Most experts would not consider MDT in patients with 3 lesions in both the liver and lung regardless of distribution or timing of metastatic disease diagnosis (6 vs. 36 months after definitive treatment). Similarly, for patients with retroperitoneal lymph node and lung and liver involvement, most experts would not offer MDT regardless of timing of metastatic disease diagnosis. In general, SOs were willing to consider MDT in patients with more advanced disease, ROs were more willing to offer treatment regardless of metastatic site location, and MOs were the least likely to consider MDT. CONCLUSIONS: Among experts caring for patients with mCRC, significant variation was noted among MOs, ROs, and SOs in the distribution and volume of metastatic disease for which MDT would be considered. This variability highlights differing opinions on management of these patients and underscores the need for well-designed prospective randomized trials to characterize the risks and potential benefits of MDT.

Neoadjuvant therapy for localized pancreatic ductal adenocarcinoma.

Pancreatic ductal adenocarcinoma (PDAC) is a highly aggressive tumor with poor prognosis and rising incidence globally. Multimodal therapy that includes surgical resection and chemotherapy with or without radiation offers the best chance for optimal outcomes. The development of established criteria for anatomic staging of local primary tumors into potentially resectable (PR), borderline resectable (BR), and locally advanced (LA) has greatly clarified the optimal treatment strategies. While upfront surgical resection was traditionally the recommended approach for localized PDAC, increasingly neoadjuvant therapy (NT) is recommended prior to surgery. Whereas NT can lead to downstaging that facilitates surgical resection for BR/LA cancers, NT also enhances patient selection for surgery, improves margin-negative resection rates, and increases the odds of completing multimodality therapy for all patients with PDAC. Herein, we review the rationale for NT for localized PDAC and summarize existing and ongoing literature.

Online artificial intelligence platforms and their applicability to gastrointestinal surgical operations.

BACKGROUND: The internet is a common source of health information for patients. Interactive online artificial intelligence (AI) may be a more reliable source of health-related information than traditional search engines. This study aimed to assess the quality and perceived utility of chat-based AI responses related to 3 common gastrointestinal (GI) surgical procedures. METHODS: A survey of 24 questions covering general perioperative information on cholecystectomy, pancreaticoduodenectomy (PD), and colectomy was created. Each question was posed to Chat Generative Pre-trained Transformer (ChatGPT) in June 2023, and the generated responses were recorded. The quality and perceived utility of responses were independently and subjectively graded by expert respondents specific to each surgical field. Grades were classified as "poor," "fair," "good," "very good," or "excellent." RESULTS: Among the 45 respondents (general surgeon [n = 13], surgical oncologist [n = 18], colorectal surgeon [n = 13], and transplant surgeon [n = 1]), most practiced at an academic facility (95.6%). Respondents had been in practice for a mean of 12.3 years (general surgeon, 14.5 ± 7.2; surgical oncologist, 12.1 ± 8.2; colorectal surgeon, 10.2 ± 8.0) and performed a mean 53 index operations annually (cholecystectomy, 47 ± 28; PD, 28 ± 27; colectomy, 81 ± 44). Overall, the most commonly assigned quality grade was "fair" or "good" for most responses (n = 622/1080, 57.6%). Most of the 1080 total utility grades were "fair" (n = 279, 25.8%) or "good" (n = 344, 31.9%), whereas only 129 utility grades (11.9%) were "poor." Of note, ChatGPT responses related to cholecystectomy (45.3% ["very good"/"excellent"] vs 18.1% ["poor"/"fair"]) were deemed to be better quality than AI responses about PD (18.9% ["very good"/"excellent"] vs 46.9% ["poor"/"fair"]) or colectomy (31.4% ["very good"/"excellent"] vs 38.3% ["poor"/"fair"]). Overall, only 20.0% of the experts deemed ChatGPT to be an accurate source of information, whereas 15.6% of the experts found it unreliable. Moreover, 1 in 3 surgeons deemed ChatGPT responses as not likely to reduce patient-physician correspondence (31.1%) or not comparable to in-person surgeon responses (35.6%). CONCLUSIONS: Although a potential resource for patient education, ChatGPT responses to common GI perioperative questions were deemed to be of only modest quality and utility to patients. In addition, the relative quality of AI responses varied markedly on the basis of procedure type.

Patient Perceptions of Care Coordination during Neoadjuvant Therapy for Gastrointestinal Cancers: A Mixed Methods Analysis.

PURPOSE: Effective cancer care coordination (CCC) is an integral component of health care delivery and critical to achieving optimal oncologic outcomes. Neoadjuvant therapy (NT), the delivery of multimodality therapy prior to surgery, is inherently complex and multidisciplinary, but CCC during NT is poorly understood. The objective of this study was to characterize patient perceptions of CCC during NT using a mixed methods approach. METHODS: This study is a cross-sectional analysis of patients with gastrointestinal cancers receiving NT who participated in a prospective longitudinal cohort study evaluating their real-time experience using a customized smartphone application. Patients completed the Cancer Care Coordination Questionnaire for Patients (CCCQ-P), a 20-item validated measure of care coordination quality, six weeks after initiating NT. Items were scored on a 5-point Likert scale, and subsections on communication (13 questions) and navigation (7 questions) were calculated with higher scores signifying better CCC. Univariate linear regression was used to calculate the impact of fragmented care and other factors on perceived CCC. Semi-structured interviews were conducted among a convenience sample of patients (n = 5); transcribed interviews were then coded using an inductive approach. RESULTS: Among 82 participants, mean age was 61 years old, 68% were male, and mean number of comorbidities was 1.68. Overall (mean 76.6 out of 100), communication subsection (48.6 out of 65), and navigation subsection (28.0 out of 35) CCCQ-P scores suggested overall positive perceptions of care coordination. Qualitative analysis of patient interviews highlighted the need for coordination among physicians before communicating the plan to patients as well as the importance of providers communicating plans in verbal and written form. CONCLUSIONS: Successful completion of NT requires significant care coordination between patients and healthcare professionals. Yet, in this cross-sectional analysis of patients on a prospective cohort study, patient perceptions of CCC during NT were overall positive. Future research should focus on optimizing other aspects of care delivery in order to improve outcomes of NT.

Association of Racial and Economic Privilege on Postoperative Outcomes Among Medicare Beneficiaries.

INTRODUCTION: Social determinants of health can play an important role in patient health. Privilege is a right, benefit, advantage, or opportunity that can positively affect all social determinants of health. We sought to assess variations in the prevalence of privilege among patient populations and define the association of privilege on postoperative surgical outcomes. METHODS: Medicare beneficiaries who underwent elective coronary artery bypass grafting, abdominal aortic aneurysm repair, total hip arthroplasty, total knee arthroplasty, colectomy, and lung resection were identified. The Index of Concentration of Extremes (ICE), a validated metric of both social spatial polarization and privilege was calculated and merged with county-level data obtained from the American Community Survey. Textbook outcome (TO) was defined as absence of postoperative complications, extended length of stay, 90-day mortality, and 90-day readmission. Multivariable regression analysis was performed to assess the relationship between ICE and TO. RESULTS: Among 1,885,889 Medicare beneficiaries who met inclusion criteria, 655,980 (34.8%) individuals resided in areas with the highest privilege (i.e., White, high-income homogeneity), whereas 221,314 (11.7%) individuals resided in areas of the lowest privilege (i.e., Black, low-income homogeneity). The overall incidence of TO was 66.2% (n = 1,247,558). On multivariable regression, residence in the most advantaged neighbourhoods was associated with a lower chance of surgical complications (odds ratio [OR] 0.90, 95% confidence interval [CI] 0.88-0.91), a prolonged length of stay (OR 0.81, 95% CI 0.79-82), 90-day readmission (OR 0.94, 95% CI 0.92-0.95), and 90-day mortality (OR 0.71, 95% CI 0.68-0.74) (all P < 0.001). Residence in the most privileged areas was associated with 19% increased odds of achieving TO (OR 1.19, 95% CI 1.18-1.21), as well as a 6% reduction in Medicare expenditures versus individuals in the least privileged counties (OR 0.94, 95% CI 0.94-0.94) (both P < 0.001). CONCLUSIONS: Privilege, based on the ICE joint measure of racial/ethnic and economic spatial concentration, was strongly associated with the likelihood to achieve an "optimal" TO following surgery. As healthcare is a basic human right, privilege should not be associated with disparities in surgical care.

Variation in Hospital Mortality After Complex Cancer Surgery: Patient, Volume, Hospital or Social Determinants?

INTRODUCTION: We sought to define the individual contributions of patient characteristics (PCs), hospital characteristics (HCs), case volume (CV), and social determinants of health (SDoH) on in-hospital mortality (IHM) after complex cancer surgery. METHODS: The California Department of Health Care Access and Information database identified patients who underwent esophagectomy (ES), pneumonectomy (PN), pancreatectomy (PD), or proctectomy (PR) for a malignant diagnosis between 2010 and 2020. Multi-level multivariable regression was performed to assess the proportion of variance explained by PCs, HCs, CV and SDoH on IHM. RESULTS: A total of 52,838 patients underwent cancer surgery (ES: n = 2,700, 5.1%; PN: n = 30,822, 58.3%; PD: n = 7530, 14.3%; PR: n = 11,786, 22.3%) across 294 hospitals. The IHM for the overall cohort was 1.7% and varied from 4.4% for ES to 0.8% for PR. On multivariable regression, PCs contributed the most to the variance in IHM (overall: 32.0%; ES: 21.6%; PN: 28.0%; PD: 20.3%; PR: 39.9%). Among the overall cohort, CV contributed 2.4%, HCs contributed 1.3%, and SDoH contributed 1.2% to the variation in IHM. CV was the second highest contributor to IHM among ES (5.3%), PN (5.3%), and PD (5.9%); however, HCs were a more important contributor among patients who underwent PR (8.0%). The unexplained variance in IHM was highest among ES (72.4%), followed by the PD (67.5%) and PN (64.6%) patient groups. CONCLUSIONS: PCs are the greatest underlying contributor to variations in IHM following cancer surgery. These data highlight the need to focus on optimizing patients and exploring unexplained sources of IHM to improve quality of surgical care.

Association of surgeon-patient sex concordance with postoperative outcomes following complex cancer surgery.

BACKGROUND AND OBJECTIVES: Sex concordance may impact the therapeutic relationship and provider-patient interactions. We sought to define the association of surgeon-patient sex concordance on postoperative patient outcomes following complex cancer surgery. METHODS: Patients who underwent surgery for lung, breast, hepato-pancreato-biliary, or colorectal cancer between 2014 and 2020 were identified from the Medicare Standard Analytic Files. The impact of surgeon-patient sex concordance or discordance on achieving an optimal postoperative textbook outcome (TO) was assessed using multivariable logistic regression. RESULTS: Among 495 628 patients, 241 938 (48.8%) patients were sex concordant with their surgeon while 253 690 (51.2%) patients were sex discordant. Sex discordance between surgeon and patient was associated with a decreased likelihood to achieve a postoperative TO (odds ratio [OR]: 0.95, 95% CI: 0.93-0.97; p < 0.001). Sex discordance was associated with a higher risk of complications (OR: 1.05, 95% CI: 1.03-1.07; p < 0.001) and 90-day mortality (OR: 1.05, 95% CI: 1.01-1.09; p = 0.011). Of note, male patients treated by female surgeons (OR: 0.96, 95% CI: 0.93-0.99; p = 0.017) had a similar lower likelihood to achieve a TO as female patients treated by male surgeons (OR: 0.90, 95% CI: 0.86-0.93; p < 0.001). CONCLUSIONS: Sex discordance was associated with a reduced likelihood of achieving an "optimal" postoperative course following complex cancer surgery.

Evaluating the caregiver experience during neoadjuvant therapy for pancreatic ductal adenocarcinoma.

INTRODUCTION: Neoadjuvant therapy (NT) is increasingly recommended for patients with localized pancreatic ductal adenocarcinoma (PDAC). Recent research has highlighted the significant treatment burden that patients experience during NT, but caregiver well-being during NT is poorly understood. METHODS: A cross-sectional mixed-methods analysis of primary caregivers of patients with localized PDAC receiving NT was undertaken. All patients completed the Caregiver Quality of Life Index-Cancer (CQOLC) survey, while semi-structured interviews were conducted among a convenience sample of participants. RESULTS: Among 28 caregivers, the mean age was 60.1 years, and most were patient spouses/significant others (71.4%). Patients had resectable (18%), borderline resectable (46%), or locally advanced (36%) PDAC with a mean treatment duration of 2.9 months at the time of their caregiver's enrollment. Most caregivers felt that they received adequate emotional/psychosocial support (80%) and understood the rationale for NT (93%). A majority (60%) reported that caregiving responsibilities impacted their daily lives and required a decrease in their work hours, leading to financial challenges (47%). While overall QOL was moderate (mean 83 ± 21.1, range 0-140), "emotional burden" (47.3 ± 20.9), and "positive adaption" (57.3 ± 13.9) were the lowest ranked CQOLC subsection scores. DISCUSSION: Caregivers of patients with PDAC undergoing NT experience significant emotional symptoms and impact on their daily lives. Assessing caregiver needs and providing resources during NT should be a priority.

Mediators of racial disparities in postoperative outcomes among patients undergoing complex surgery.

BACKGROUND: This study sought to quantify the direct and indirect effects of race on postoperative outcomes after complex surgery. METHODS: Medicare patients who underwent abdominal aortic aneurysm (AAA) repair, coronary artery bypass grafting (CABG), lung resection or colectomy were identified (2014-2018). Generalized structural equation modelling was utilized to quantify the direct and indirect effects of race on Textbook outcome (TO). RESULTS: Among 930,033 patients, 46.8% of patients achieved a TO, with Black patients less likely to achieve a TO (referent: White; Black: OR 0.72, 95% CI 0.70-0.73). Notably, 32.3% of the disparities in TO were attributable to race itself, while 67.7% was explained by other factors. Specifically, residential segregation accounted for 39.4% of the lower TO rates among Black patients, while 21.0% was attributable to a high comorbidity burden. CONCLUSIONS: These data highlight the need to target structural racism as a policy priority to promote a more equitable healthcare system.

Quality of Life and Real-time Patient Experience During Neoadjuvant Therapy: A Prospective Cohort Study.

OBJECTIVE: To use a customized smartphone application to prospectively measure QOL and the real-time patient experience during neoadjuvant therapy (NT). BACKGROUND: NT is increasingly used for patients with localized gastrointestinal (GI) cancers. There is little data assessing patient experience and quality of life (QOL) during NT for GI cancers. METHODS: Patients with GI cancers receiving NT were instructed on using a customized smartphone application through which the Functional Assessment of Cancer Therapy-General (FACT-G) questionnaire, a validated measure of health-related QOL, was administered at baseline, every 30 days, and at the completion of NT. Participants also tracked their moods and symptoms and used free-text journaling functionalities in the application. Mean overall and subsection health-related QOL scores were calculated during NT. RESULTS: Among 104 enrolled patients, the mean age was 60.5 ± 11.5 years and 55% were males. Common cancer diagnoses were colorectal (40%), pancreatic (37%), and esophageal (15%). Mean overall FACT-G scores did not change during NT ( P = 0.987). While functional well-being scores were consistently the lowest and social well-being scores the highest, FACT subscores similarly did not change during NT (all P > 0.01). The most common symptoms reported during NT were fatigue, insomnia, and anxiety (39.3%, 34.5%, and 28.3% of patient entries, respectively). Qualitative analysis of free-text journaling entries identified anxiety, fear, and frustration as the most common themes, but also the importance of social support systems and confidence in health care providers. CONCLUSIONS: While patient symptom burden remains high, results of this prospective cohort study suggest QOL is maintained during NT for localized GI cancers.

Impact of Medicaid expansion on the multimodal treatment of biliary tract cancer.

INTRODUCTION: The impact of Medicaid expansion (ME) on the treatment of patients with cancer remains controversial, especially individuals requiring complex multidisciplinary care. We sought to evaluate the impact of Medicaid expansion (ME) on receipt of multimodal care, including surgical resection, for Stage I-III biliary tract cancer (BTC). METHODS: Patients diagnosed with BTC between 40 and 65 years of age were identified from the National Cancer Database and divided into pre- (2008-2012) and post- (2015-2018) ME cohorts. Difference-in-difference (DID) analysis was used to determine the impact of ME on the utilization of surgery and multimodal chemotherapy and/or radiotherapy treatment for BTC. RESULTS: Among 12,415 patients with BTC (extrahepatic, n = 5622, 45.3%; intrahepatic, n = 4352, 35.1%; gallbladder, n = 1944, 15.7%; overlapping, n = 497, 4.0%), 5835 (47.0%) and 6580 (53.0%) patients were diagnosed before versus after ME, respectively. Overall utilization of surgery (OR 1.13, 95% CI 1.02-1.26) and multimodality therapy (OR 1.13, 95% CI 1.01-1.27) increased in states that adopted ME. Utilization of surgery among uninsured/Medicaid patients in ME states increased relative to patients living in non-ME states (∆+10.1%, p = 0.01). Similarly, the use of multimodal treatment increased among uninsured/Medicaid patients living in ME versus non-ME states (∆+6.4%, p = 0.04); in contrast, there were no difference among patients with other insurance statuses (overall: ∆+1.5%, private: ∆-2.0%, other: ∆+3.9%, all p > 0.5). Uninsured/Medicaid patients with BTC who lived in a ME state had a lower risk of long-term death in the post-ME era (HR 0.81, 95% CI 0.67-0.98; p = 0.03). CONCLUSIONS: Implementation of ME positively impacted survival among patients who underwent surgical and multimodal treatment for Stage I-III BTC.
