Assessment of Caregivers' Burden When Caring for Patients With Pancreatic and Periampullary Cancer.

BACKGROUND: Family and other unpaid caregivers play an active role in the recovery of individuals with pancreatic and periampullary cancer after pancreatectomy. However, little is known about caregivers' experiences and how to better support them. METHODS: Caregivers accompanying patients to 1-month postpancreatectomy visits at 3 hospitals completed an electronic survey between November 2018 and February 2020. We examine measures of absenteeism and work productivity loss among the subset of caregivers who reported working for pay and comparatively assess caregiver experiences by employment status. All analyses were performed as 2-sided tests. RESULTS: Of 265 caregivers approached for study participation, 240 (90.6%) enrolled. Caregivers were primarily female (70.8% female, 29.2% male) and spouses (58.3%) or adult children (25.8%) of patients, with a median age of 60 years. Of the 240 caregivers included in the study, 107 (44.6%) worked for pay. Nearly half (44.4%) of working caregivers reported being absent from work because of caregiving amounting to a 14% loss in work hours. While at work, 58.9% of working caregivers reported increased work difficulty as a result of caregiving. Taken together, an estimated 59.7% loss in work productivity was experienced because of caregiving in the month following pancreatectomy. After adjustment for sociodemographic factors, working (vs nonworking) caregivers reported increased financial (odds ratio [OR] = 2.32; P = .04) and emotional (OR = 1.93; P = .04) difficulties and daily activity restrictions (OR = 1.85; P = .048). CONCLUSIONS: Working caregivers of patients with pancreatic and periampullary cancer experience negative impacts on work and productivity, and caregiving-related financial and emotional difficulties may be amplified. This study highlights the need for workplace policies to support unpaid cancer caregiving.

Assessment of the Long-Term Impact of Pancreatoduodenectomy on Health-Related Quality of Life Using the EORTC QLQ-PAN26 Module.

BACKGROUND: Long-term pancreatoduodenectomy (PD) survivors have previously reported favorable quality of life (QoL). However, there has been a paucity of studies utilizing pancreas-specific modules for QoL assessment, which may uncover disability that general modules cannot detect. METHODS: The European Organisation for Research and Treatment of Cancer (EORTC) QLQ-C30 and QLQ-PAN26 questionnaires were administered to PD survivors who were at least 5 years out of their operations for neoplasms (1998-2011, study cohort) and compared their scores with published preoperative scores of patients with pancreatic cancer (control cohort). The clinical relevance (CR) of differences was scored as small (5-10), moderate (10-20), or large (> 20) based on validated interpretation of clinically important differences. RESULTS: Of 1266 patients who underwent PD, there were 305 survivors with valid contact information, of whom 248 responded to the questionnaire (response rate 81.3%) and made up the study cohort. The median follow-up was 9.1 years (range 5.1-21.2 years). When compared with the control cohort, patients in the study cohort reported higher pancreatic pain (41.7 ± 17.6 vs. 18.1 ± 20.5, p < 0.001, CR large), sexuality dissatisfaction (63.0 ± 37.5 vs. 35.1 ± 34.3, p < 0.001, CR large), altered bowel habits (37.6 ± 30.6 vs. 20.0 ± 24.5, p < 0.001, CR moderate), and digestive symptoms (26.3 ± 29.5 vs. 18.7 ± 27.8, p = 0.002, CR small) scores. There was a higher prevalence of bloating, indigestion, and flatulence, but lower prevalence of future health worry (71.7% vs. 89.6%, p < 0.001) and limitation in planning activities (30.1% vs. 48.3%, p < 0.001) at 5 years. CONCLUSION: While post-PD patients had better long-term global QoL than healthy controls, a more granular, pancreas-specific questionnaire uncovered digestive abnormalities and sexuality dissatisfaction. These data can better inform clinical decision making and provide potential areas for improvement and patient support.

Patient and Caregiver Considerations and Priorities When Selecting Hospitals for Complex Cancer Care.

BACKGROUND: Healthcare policies have focused on centralizing care to high-volume centers in an effort to optimize patient outcomes; however, little is known about patients' and caregivers' considerations and selection process when selecting hospitals for care. We aim to explore how patients and caregivers select hospitals for complex cancer care and to develop a taxonomy for their selection considerations. METHODS: This was a qualitative study in which data were gathered from in-depth interviews conducted from March to November 2019 among patients with hepatopancreatobiliary cancers who were scheduled to undergo a pancreatectomy (n = 20) at a metropolitan, urban regional, or suburban medical center and their caregivers (n = 10). RESULTS: The interviews revealed six broad domains that characterized hospital selection considerations: hospital factors, team characteristics, travel distance to hospital, referral or recommendation, continuity of care, and insurance considerations. The identified domains were similar between participants seen at the metropolitan center and urban/suburban medical centers, with the following exceptions: participants receiving care specifically at the metropolitan center noted operative volume and access to specific services such as clinical trials in their hospital selection; participants receiving care at urban/suburban centers noted health insurance considerations and having access to existing medical records in their hospital selection. CONCLUSIONS: This study delineates the many considerations of patients and caregivers when selecting hospitals for complex cancer care. These identified domains should be incorporated into the development and implementation of centralization policies to help increase patient access to high-quality cancer care that is consistent with their priorities and needs.

Simulated Volume-Based Regionalization of Complex Procedures: Impact on Spatial Access to Care.

OBJECTIVE: This study simulates the regionalization of pancreatectomies to assess its impact on spatial access in terms of patient driving times. BACKGROUND: Although policies to regionalize complex procedures to high-volume centers may improve outcomes, the impact on patient access is unknown. METHODS: Patients who underwent pancreatectomies from 2005 to 2014 were identified from California's statewide database. Round-trip driving times between patients' home ZIP code and hospital addresses were calculated via Google Maps. Regionalization was simulated by eliminating hospitals performing <20 pancreatectomies/yr, and reassigning patients to the next closest hospital that satisfied the volume threshold. Sensitivity analyses were performed for New York and Medicare patients to assess for influence of geography and insurance coverage, respectively. RESULTS: Of 13,317 pancreatectomies, 6335 (47.6%) were performed by hospitals with <20 cases/yr. Patients traveled a median of 49.8 minutes [interquartile range (IQR) 30.8-96.2] per round-trip. A volume-restriction policy would increase median round-trip driving time by 24.1 minutes (IQR 4.5-53.5). Population in-hospital mortality rates were estimated to decrease from 6.7% to 2.8% (P < 0.001). Affected patients were more likely to be racial minorities (44.6% vs 36.5% of unaffected group, P < 0.001) and covered by Medicaid or uninsured (16.3% vs 9.8% of unaffected group, P < 0.001). Sensitivity analyses revealed a 17.8 minutes increment for patients in NY (IQR 0.8-47.4), and 27.0 minutes increment for Medicare patients (IQR 6.2-57.1). CONCLUSIONS: A policy that limits access to low-volume pancreatectomy hospitals will increase round-trip driving time by 24 minutes, but up to 54 minutes for 25% of patients. Population mortality rates may improve by 1.5%.

A fast, simple, and cost-effective method of expanding patient-derived xenograft mouse models of pancreatic ductal adenocarcinoma.

BACKGROUND: Patient-derived xenograft (PDX) mouse models of cancer have been recognized as better mouse models that recapitulate the characteristics of original malignancies including preserved tumor heterogeneity, lineage hierarchy, and tumor microenvironment. However, common challenges of PDX models are the significant time required for tumor expansion, reduced tumor take rates, and higher costs. Here, we describe a fast, simple, and cost-effective method of expanding PDX of pancreatic ductal adenocarcinoma (PDAC) in mice. METHODS: We used two established frozen PDAC PDX tissues (derived from two different patients) and implanted them subcutaneously into SCID mice. After tissues reached 10-20 mm in diameter, we performed survival surgery on each mouse to harvest 90-95% of subcutaneous PDX (incomplete resection), allowing the remaining 5-10% of PDX to continue growing in the same mouse. RESULTS: We expanded three consecutive passages (P1, P2, and P3) of PDX in the same mouse. Comparing the times required for in vivo expansion, P2 and P3 (expanded through incomplete resection) grew 26-60% faster than P1. Moreover, such expanded PDX tissues were successfully implanted orthotopically into mouse pancreases. Within 20 weeks using only 14 mice, we generated sufficient PDX tissue for future implantation of 200 mice. Our histology study confirmed that the morphologies of cancer cells and stromal structures were similar across all three passages of subcutaneous PDX and the orthotopic PDX and were reflective of the original patient tumors. CONCLUSIONS: Taking advantage of incomplete resection of tumors associated with high local recurrence, we established a fast method of PDAC PDX expansion in mice.

Variation in long-term oncologic outcomes by type of cancer center accreditation: An analysis of a SEER-Medicare population with pancreatic cancer.

BACKGROUND: Cancer center accreditation is designed to identify centers that provide high-quality cancer care. This also guides patients and referring physicians towards centers of excellence for specialized care. We sought to examine if cancer center accreditation was associated with improved long-term oncologic outcomes in patients with pancreatic adenocarcinoma. METHODS: Using the SEER-Medicare database, we identified patients who underwent pancreatectomy for pancreatic adenocarcinoma from 1996 to 2013. Hospitals were categorized into three groups: National Cancer Institute-designated (NCI-designated) centers, Commission on Cancer (CoC)-accredited centers, and "non-accredited" (NA) centers. Multilevel mixed-effects models were used to calculate adjusted examined lymph nodes, disease-specific survival (DSS), and overall survival (OS). RESULTS: We identified 5,118 patients who underwent pancreatectomy at 632 hospitals (41.0% NA, 49.6% CoC, 9.4% NCI). NCI-designated centers had a greater median number of lymph nodes examined compared with CoC-accredited or NA centers (14 vs. 10 vs. 11.0 nodes, respectively; p < 0.001). Patients treated at NCI centers had a higher 5-year DSS compared to those treated at CoC or NA centers (31.2% vs. 23.6% vs. 23.0%, respectively; p < 0.001). Finally, patients treated at NCI centers had a higher 5-year OS compared to those treated at CoC or NA centers (23.5% vs. 18.9% vs. 17.9%, respectively; p < 0.001). The associations held true when adjusted analyses were performed. CONCLUSION: Patients with resected pancreatic cancer treated at NCI-designated centers were associated with improved long-term oncologic outcomes. There was no difference between CoC-accredited centers compared with NA centers. Meticulous validation of accreditation is warranted globally prior to implementation.

Socioeconomic determinants of the surgical treatment of colorectal liver metastases.

OBJECTIVE: We hypothesized that differences in resection rates of colorectal liver metastases exist based on socioeconomic status (SES) inequalities. METHODS: The NCDB was utilized to study patients of different median household income diagnosed with colon adenocarcinoma from 2010 to 2015. RESULTS: A total of 21,258 patients met inclusion criteria, of whom 3,587 (16.9%) underwent metastasectomy. Patients of the highest income quartile were more likely to undergo metastasectomy compared to the lowest quartile (OR 1.20, CI 1.07-1.37, p = 0.003). Overall, patients in the highest income quartile had a median OS of 17.1 months compared with 13.0 months for the lowest quartile (HR 0.85, CI 0.81-0.90, p < 0.001). While metastasectomy was associated with improved OS across all groups, the disparity by income quartile widened (29.2 vs. 22.0 months, respectively; HR 0.51, CI 0.49-0.54, p < 0.001). CONCLUSION: Higher income patients were more likely to undergo metastasectomy compared with lower income patients and were associated with longer OS.

Effects of laparoscopic vs open abdominal surgery on costs and hospital readmission rate and its effect modification by surgeons' case volume.

BACKGROUND: Laparoscopy provides a minimally invasive alternative to open abdominal surgery. Current data describing its association with hospital readmission and costs in relation to surgeon laparoscopic case volume is limited to smaller databases and subsets of operations. METHODS: This retrospective cohort study of 23,285 adult abdominal operations from 2007 to 2015 compares 30-day readmission rate and costs between laparoscopic and open abdominal operations and examines effect modification by surgeon laparoscopic case volume. Outcomes were all-cause hospital readmission within 30 days after discharge and index hospital admission cost. RESULTS: All-cause hospital readmission rates were significantly lower after laparoscopic abdominal operations compared with open operations (adjusted odds ratio [aOR] 0.56, 95% CI 0.46-0.69, p < 0.001) with a difference in readmission risk attributable to laparoscopic approach of - 4.0% (95% CI - 5.4 to - 2.6%) in complete-case analysis. Among surgeons with a high laparoscopic case volume, the estimated difference in readmission risk through laparoscopy was magnified (- 5.8%, 95% CI - 7.5 to - 4.1%) compared to low surgeon laparoscopic case volume (- 2.9%, 95% CI - 4.8 to -1.1%, p for interaction = 0.005). The estimated difference in costs of the index hospital admission attributable to laparoscopic approach was - $3869 (95% CI - $4200 to - $3538; adjusted incidence rate ratio 0.77, 95% CI 0.75-0.79, p < 0.001). Laparoscopy was followed by significantly lower rates of readmissions related to gastrointestinal (aOR 0.68, 95% CI 0.55-0.85, p = 0.001), wound complications (infection: aOR 0.33, 95% CI 0.23-0.47, p < 0.001; non-infectious: aOR 0.47, 95% CI 0.30-0.74, p = 0.001), and malignancy (aOR 0.68, 95% CI 0.55-0.85, p < 0.001). The findings remain robust after multiple imputation and sensitivity analyses. CONCLUSIONS: Laparoscopy versus open abdominal surgery is associated with reduced hospital readmissions related to malignancy, gastrointestinal, and wound complications. Effect modification by higher laparoscopy case volume argues for continued proliferation of laparoscopy in abdominal surgeries.

Neoadjuvant FOLFIRINOX for Patients with Borderline Resectable or Locally Advanced Pancreatic Cancer: Results of a Decision Analysis.

BACKGROUND: The effectiveness and cost-effectiveness of using neoadjuvant FOLFIRINOX (nFOLFIRINOX) for patients with borderline resectable or locally advanced pancreatic ductal adenocarcinoma (BR/LA PDAC) are unknown. Our objective was to determine whether nFOLFIRINOX is more effective or cost-effective for patients with BR/LA PDAC compared with upfront resection surgery and adjuvant gemcitabine plus capecitabine (GEM/CAPE) or gemcitabine monotherapy (GEM). MATERIALS AND METHODS: We performed a decision-analysis to assess the value of nFOLFIRINOX versus GEM/CAPE or GEM using a mathematical simulation model. Model transition probabilities were estimated using published and institutional clinical data. Model outcomes included overall and disease-free survival, quality-adjusted life-years (QALYs), cost in U.S. dollars, and cost-effectiveness expressed as an incremental cost-effectiveness ratio. Deterministic and probabilistic sensitivity analyses explored the uncertainty of model assumptions. RESULTS: Model results found median overall survival (34.5/28.0/22.0 months) and disease-free survival (15.0/14.0/13.0 months) were better for nFOLFIRINOX compared with GEM/CAPE and GEM. nFOLFIRINOX was the optimal strategy on an efficiency frontier, resulting in an additional 0.35 life-years, or 0.30 QALYs, at a cost of $46,200/QALY gained compared with GEM/CAPE. Sensitivity analysis found that cancer recurrence and complete resection rates most affected model results, but were otherwise robust. Probabilistic sensitivity analyses found that nFOLFIRINOX was cost-effective 92.4% of the time at a willingness-to-pay threshold of $100,000/QALY. CONCLUSION: Our modeling analysis suggests that nFOLFIRINOX is preferable to upfront surgery for patients with BR/LA PDAC from both an effectiveness and cost-effectiveness standpoint. Additional clinical data that further define the long-term effectiveness of nFOLFIRINOX are needed to confirm our results. IMPLICATIONS FOR PRACTICE: Increasingly, neoadjuvant FOLFIRINOX has been used for borderline resectable and locally advanced pancreatic cancer with the goal of rendering them resectable and decreasing risk of recurrence. Despite many efforts to show the benefits of neoadjuvant over adjuvant therapies, clinical evidence to guide this decision is largely lacking. Decision-analytic modeling can provide a methodologic platform that integrates the best available data to quantitatively explore clinical decisions by simulating a hypothetical clinical trial. This modeling analysis suggests that neoadjuvant FOLFIRINOX is preferable to upfront surgery and adjuvant therapies by various outcome metrics including quality-adjusted life years, overall survival, and incremental cost-effectiveness ratio.

Number of Examined Lymph Nodes and Nodal Status Assessment in Distal Pancreatectomy for Body/Tail Ductal Adenocarcinoma.

OBJECTIVE: First, to assess the impact of the number of examined lymph nodes (ELNs) on staging and survival after distal pancreatectomy (DP) for pancreatic adenocarcinoma (PDAC). Second, to identify the minimum number of ELNs (MNELNs) ensuring an accurate detection of nodal involvement. Third, to reappraise the role of lymph node (LN) parameters, including N-status and lymph node ratio (LNR). BACKGROUND: In contrast with pancreatoduodenectomy, information on LN staging and the MNELN required in DP is lacking. METHODS: Patients undergoing DP for PDAC at 2 academic hospitals from 2000 through 2013 were retrospectively analyzed. The eighth edition of the American Joint Committee on Cancer staging system was used. The MNELN was estimated using the binomial probability law. Survival analyses were performed separately for node-negative and node-positive patients using univariable and multivariable models. RESULTS: The study population consisted of 240 patients. The median number of ELN was 21, significantly lower in node-negative patients as compared with node-positive patients (18.5 vs 24.0; P = 0.001). The proportion of node-positive patients increased with increasing numbers of ELNs, whereas LNR showed an inverse trend. The estimated MNELN was 20. The number of ELN (≥ or <20) was an independent prognostic factor only in node-negative patients [odds ratio (OR) 3.23 for ELN <20), suggesting a stage migration effect. In node-positive patients, N2-class, but not LNR, was a significant predictor of survival at multivariable analysis (OR 1.68). CONCLUSION: The number of ELN affects nodal staging in body/tail PDAC. At least 20 LNs are required for correct staging. N-status is superior to LNR in predicting survival of node-positive patients.

Hepatocellular Carcinoma in Transplantable Child-Pugh A Cirrhotics: Should Cost Affect Resection vs Transplantation?

BACKGROUND: There is no consensus regarding the optimal surgical treatment for transplantable hepatocellular carcinoma (HCC) patients with well-compensated cirrhosis. Our aim was to compare outcomes between Child-Pugh A (CPA) cirrhotics who underwent liver resection or transplantation for HCC. METHODS: Clinicopathologic data were retrospectively collected for all surgically treated HCC patients between 7/1992 and 12/2015. Disease-free survival (DFS) and overall survival (OS) were calculated from the time of operation or diagnosis (intention-to-treat analysis including patients removed from the transplant list). The average overall cost including pre-operative and post-operative procedures was calculated for each group. RESULTS: Of the 513 surgically treated HCC patients, 184 had CPA cirrhosis and fulfilled the Milan criteria (MC). Of those, 95 (52%) were resected and 89 (48%) were transplanted. Twenty-two patients were removed from the transplant list. Transplanted patients were younger (p < 0.001), had a higher MELD score (p < 0.001) and a higher frequency of hepatitis C (p < 0.001). Length of stay and postoperative complication rates were similar between groups. DFS was longer for transplanted patients (3-, 5-, and 10-year DFS rates 48, 44, 31% vs 96, 94, 94%, respectively, p < 0.001). OS was similar between groups (3-, 5-, and 10-year OS rates 76, 62, 41% vs 82, 77, 53%, respectively, p = 0.07). Only size of greatest lesion and T stage were independent predictors of OS. The cost was much higher for the transplant group, even when accounting for the treatment of recurrences ($37,391 vs $137,996). CONCLUSIONS: Since OS is similar between CPA cirrhotics within the MC undergoing resection or transplantation for HCC, but cost is significantly higher for transplantation. Resection should be considered for first-line treatment.

International Scholarship Programs of the American College of Surgeons: Expansion of the Global Surgical Network.

BACKGROUND: The American College of Surgeons has always promoted education and collaborations with other countries and their scientific organizations. The International Guest Scholarship program was established in 1968 to support the travel of foreign surgeons to medical Institutions in the USA and Canada. The program has grown substantially over time and now includes different categories of scholarships and surgeons. The objective of this article is to describe the experiences gained by the international scholars who visited US and Canadian institutions through these ACS programs. STUDY DESIGN: In order to collect information regarding these scholarships from the surgeons who have already participated in the program, an Internet-based survey was e-mailed to alumni. The surveys were constructed to gather career information on former scholars and to analyze the perceived impact of these programs on their careers. RESULTS: Among the international scholarships alumni, most are now Fellows of the American College of Surgeons. The majority of respondents maintained contact with their host surgeons in the USA or Canada; they began or continued research, surgical education and surgical quality improvement initiatives in their country of origin based upon their experiences as international scholars. Most of the alumni reported that the experience they had during the scholarship was inspiring, opened their minds and broadened their horizons. CONCLUSIONS: The overall effect of ACS international scholarship program should be considered as positive, as 80-90% of respondent alumni consider their experience very helpful and feel that it provided them with opportunities that would not have been possible without it. It is incumbent upon the ACS to continue along this path by identifying funding and donation sources, as well as enriching the content and goals.

Health-related Quality of Life and Functional Outcomes in 5-year Survivors After Pancreaticoduodenectomy.

OBJECTIVE: Our aim was to assess quality of life (QOL) and functionality in a large cohort of patients ≥5-years after pancreaticoduodenectomy (PD). BACKGROUND: Long-term QOL outcomes after PD for benign or malignant disease are largely undocumented. METHODS: We administered the EORTC QLQ-C30 questionnaire to patients who underwent PD for neoplasms from 1998 to 2011 and compared their scores with an age- and sex-matched normal population. Clinical relevance (CR) of differences was scored as small (5-10), moderate (10-20), or large (>20) based on validated interpretation of clinically important differences. RESULTS: Of 305 PD survivors, 245 (80.3%) responded, of whom 157 (64.1%) underwent PD for nonmalignant lesions. Median follow-up was 9.1 years (range 5.1 -21.2 yrs). New-onset diabetes developed in 10.6%; 50.4% reported taking pancreatic enzymes; 54.6% reported needing antacids. Compared with the age- and sex-adjusted controls, PD survivors demonstrated higher global QOL (78.7 vs 69.7, CR small, P < 0.001), physical (86.7 vs 77.9, CR small, P < 0.001) and role-functioning scores (86.3 vs 74.1, CR medium, P < 0.001). Using linear regression and adjusting for socioeconomic variables, there were no differences in QOL or functional scores in the benign versus malignant subgroups. Older age at operation was associated with worse physical-functioning (-0.4/yr, P = 0.008). Taking pancrelipase (-6.8, P = 0.035) or antacids (-6.3, P = 0.044) were both associated with lower social-functioning scores. CONCLUSIONS: Patients who had a PD demonstrated better global QOL, physical- and role-functioning scores at 5-years when compared with age- and sex-matched controls. Approximately half of the patients required pancreatic enzyme replacement, while only 11% developed new-onset diabetes.

Potential impact of a volume pledge on spatial access: A population-level analysis of patients undergoing pancreatectomy.

BACKGROUND: A minimum-volume policy restricting hospitals not meeting the threshold from performing complex operation may increase travel burden and decrease spatial access to operation. We aim to identify vulnerable populations that would be sensitive to an added travel burden. METHODS: We performed a retrospective analysis of the database of the California Office of Statewide Health Planning and Development for patients undergoing pancreatectomy from 2005 to 2014. Number of hospitals bypassed was used as a metric for travel. Patients bypassing fewer hospitals were deemed to be more sensitive to an added travel burden. RESULTS: There were 13,374 patients who underwent a pancreatectomy, of whom 2,368 (17.7%) were nonbypassers. On unadjusted analysis, patients >80 year old travelled less than their younger counterparts, bypassing a mean of 10.9 ± 9.5 hospitals compared with 14.2 ± 21.3 hospitals bypassed by the 35-49 year old age group (P < .001). Racial minorities travelled less when compared with non-Hispanic whites (P < .001). Patients identifying their payer status as self-pay (8.9 ± 15.6 hospitals bypassed) and Medicaid (10.1 ± 17.2 hospitals bypassed) also travelled less when compared with patients with private insurance (13.8 ± 20.4 hospitals bypassed, P < .001). On multivariate analysis, advanced age, racial minority, and patients with self-pay or Medicaid payer status were associated independently with increased sensitivity to an added travel burden. CONCLUSION: In patients undergoing pancreatectomy, the elderly, racial minorities, and patients with self-pay or Medicaid payer status were associated with an increased sensitivity to an added travel burden. This vulnerable cohort may be affected disproportionately by a minimum-volume policy.

Surgical Education and Health Care Reform: Defining the Role and Value of Trainees in an Evolving Medical Landscape.

OBJECTIVE: Health care reform and surgical education are often separated functionally. However, especially in surgery, where resident trainees often spend twice as much time in residency and fellowship than in undergraduate medical education, one must consider their contributions to health care. SUMMARY BACKGROUND DATA: In this short commentary, we briefly review the status of health care in the United States as well as some of the recent and current changes in graduate medical education that pertain to surgical trainees. METHODS: This is a perspective piece that draws on the interests and varied background of the multiinstitutional and international group of authors. RESULTS: The authors propose 3 main areas of focus for research and practice- (1) accurately quantifying the care provided currently by trainees, (2) determining impact to trainees and hospital systems of training parameters, focusing on long-term outcomes rather than short-term outcomes, and (3) determining practice models of education that work best for both health care delivery and trainees. CONCLUSIONS: The authors propose that surgical education must align itself with rather than separate itself from overall health care reform measures and even individual hospital financial pressures. This should not be seen as additional burden of service, but rather practical education in training as to the pressures trainees will face as future employees. Rethinking the contributions and training of residents and fellows may also synergistically work to impress to hospital administrators that providing better, more focused and applicable education to residents and fellows may have long-term, strategic, positive impacts on institutions.

Health Insurance Expansion and Treatment of Pancreatic Cancer: Does Increased Access Lead to Improved Care?

BACKGROUND: Pancreatic cancer is increasingly common and poised to become the second leading cause of cancer deaths by the year 2020. Surgical resection is the only chance for cure, yet significant disparities in resection rates exist by insurance status. The 2006 Massachusetts health care reform serves as natural experiment to evaluate the unknown impact of health insurance expansion on treatment of pancreatic cancer. STUDY DESIGN: Using the Agency for Healthcare Research and Quality's State Inpatient Databases, this cohort study examines nonelderly, adult patients with no insurance, private coverage, or government-subsidized insurance plans, who were admitted with pancreatic cancer in Massachusetts and 3 control states. The primary end point was change in pancreatic resection rates. Difference-in-difference models were used to show the impact of Massachusetts health care reform on resection rates for pancreatic cancer, controlling for confounding factors and secular trends. RESULTS: Before the Massachusetts reform, government-subsidized and self-pay patients had significantly lower rates of resection than privately insured patients. The 2006 Massachusetts health reform was associated with a 15% increased rate of admission with pancreatic cancer (p = 0.043) and a 67% increased rate of surgical resection (p = 0.043) compared with control states. Measured disparities in likelihood of resection by insurance status decreased in Massachusetts and remained unchanged in control states. CONCLUSIONS: The 2006 Massachusetts health care reform was associated with increased resection rates for pancreatic cancer compared with control states. Our findings provide hopeful evidence that increased insurance coverage can help improve equity in pancreatic cancer treatment. Additional studies are needed to evaluate the longevity of these findings and generalizability in other states.

Cytology adds value to imaging studies for risk assessment of malignancy in pancreatic mucinous cysts.

OBJECTIVE: Evaluate the value of cytology relative to imaging features in risk assessment for malignancy as defined in the Sendai Guidelines. BACKGROUND: The Sendai Guidelines list symptoms, cyst size >30 mm, dilated main pancreatic duct (MPD) >6 mm, mural nodule (MN) and "positive" cytology as high risk stigmata for malignancy warranting surgical triage. METHODS: We reviewed clinical, radiological and cytological data of 112 patients with histologically confirmed mucinous cysts of the pancreas evaluated in a single tertiary medical center. Cytology slides were blindly re-reviewed and epithelial cells grouped as either benign or high-grade atypia (HGA) [≥high-grade dysplasia]. Histologically, neoplasms were grouped as benign (low-grade and moderate dysplasia) and malignant (in situ and invasive carcinoma). Performance characteristics of cytology relative to other risk factors were evaluated. RESULTS: Dilated MPD, MN, and HGA were independent predictors of malignancy (p < 0.0001), but not symptoms (p = 0.29) or cyst size >30 mm (p = 0.51). HGA was the most sensitive predictor of malignancy in all cysts (72%) and in small (≤30 mm) branch-duct intraductal papillary mucinous neoplasm (BD IPMN; 67%), whereas also being specific (85 and 88%, respectively). MN and dilated MPD were highly specific (>90%), but insensitive (39%-44%). Cytology detected 30% more cancers in small cysts than dilated MPD or MN and half of the cancers without either of these high-risk imaging features. CONCLUSIONS: Cytology adds value to the radiological assessment of predicting malignancy in mucinous cysts, particularly in small BD IPMN.

Intrahepatic cholangiocarcinoma: an international multi-institutional analysis of prognostic factors and lymph node assessment.

PURPOSE: To identify factors associated with outcome after surgical management of intrahepatic cholangiocarcinoma (ICC) and examine the impact of lymph node (LN) assessment on survival. PATIENTS AND METHODS: From an international multi-institutional database, 449 patients who underwent surgery for ICC between 1973 and 2010 were identified. Clinical and pathologic data were evaluated using uni- and multivariate analyses. RESULTS: Median tumor size was 6.5 cm. Most patients had a solitary tumor (73%) and no vascular invasion (69%). Median survival was 27 months, and 5-year survival was 31%. Factors associated with adverse prognosis included positive margin status (hazard ratio [HR], 2.20; P < .001), multiple lesions (HR, 1.80; P = .001), and vascular invasion (HR, 1.59; P = .015). Tumor size was not a prognostic factor (HR, 1.03; P = .23). Patients were stratified using the American Joint Committee on Cancer/International Union Against Cancer T1, T2a, and T2b categories (seventh edition) in a discrete step-wise fashion (P < .001). Lymphadenectomy was performed in 248 patients (55%); 74 of these (30%) had LN metastasis. LN metastasis was associated with worse outcome (median survival: N0, 30 months v N1, 24 months; P = .03). Although patients with no LN metastasis were able to be stratified by tumor number and vascular invasion (N0; P < .001), among patients with N1 disease, multiple tumors and vascular invasion, either alone or together, failed to discriminate patients into discrete prognostic groups (P = .34). CONCLUSION: Although tumor size provides no prognostic information, tumor number, vascular invasion, and LN metastasis were associated with survival. N1 status adversely affected overall survival and also influenced the relative effect of tumor number and vascular invasion on prognosis. Lymphadenectomy should be strongly considered for ICC, because up to 30% of patients will have LN metastasis.
