ABSTRACT

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.

ABSTRACT

BACKGROUND: Pancreatic cancer often presents as locally advanced (LAPC) or borderline resectable (BRPC). Neoadjuvant systemic therapy is recommended as initial treatment. It is currently unclear what chemotherapy should be preferred for patients with BRPC or LAPC. METHODS: We performed a systematic review and multi-institutional meta-analysis of patient-level data regarding the use of initial systemic therapy for BRPC and LAPC. Outcomes were reported separately for tumor entity and by chemotherapy regimen including FOLFIRINOX (FIO) or gemcitabine-based. RESULTS: A total of 23 studies comprising 2930 patients were analyzed for overall survival (OS) calculated from the beginning of systemic treatment. OS for patients with BRPC was 22.0 months with FIO, 16.9 months with gemcitabine/nab-paclitaxel (Gem/nab), 21.6 months with gemcitabine/cisplatin or oxaliplatin or docetaxel or capecitabine (GemX), and 10 months with gemcitabine monotherapy (Gem-mono) (p < 0.0001). In patients with LAPC, OS also was higher with FIO (17.1 months) compared with Gem/nab (12.5 months), GemX (12.3 months), and Gem-mono (9.4 months; p < 0.0001). This difference was driven by the patients who did not undergo surgery, where FIO was superior to other regimens. The resection rates for patients with BRPC were 0.55 for gemcitabine-based chemotherapy and 0.53 with FIO. In patients with LAPC, resection rates were 0.19 with Gemcitabine and 0.28 with FIO. In resected patients, OS for patients with BRPC was 32.9 months with FIO and not different compared to Gem/nab, (28.6 months, p = 0.285), GemX (38.8 months, p = 0.1), or Gem-mono (23.1 months, p = 0.083). A similar trend was observed in resected patients converted from LAPC. CONCLUSIONS: In patients with BRPC or LAPC, primary treatment with FOLFIRINOX compared with Gemcitabine-based chemotherapy appears to provide a survival benefit for patients that are ultimately unresectable. For patients that undergo surgical resection, outcomes are similar between GEM+ and FOLFIRINOX when delivered in the neoadjuvant setting.

ABSTRACT

BACKGROUND: Modern chemotherapeutics have led to improved systemic disease control for patients with locally advanced pancreatic cancer (LAPC). Surgical strategies such as distal pancreatectomy with celiac axis resection (DP-CAR) are increasingly entertained. Herein we review procedure-specific outcomes and assess biologic rationale for DP-CAR. METHODS: A prospectively maintained single-institution database of all pancreatectomies was queried for patients undergoing DP-CAR. We excluded all patients for whom complete data were not available and those who were not treated with contemporary multi-agent therapy. Data were supplemented with dedicated chart review and outreach for long-term oncologic outcomes. RESULTS: Fifty-four patients underwent DP-CAR between 2008 and 2018. The median age was 62.7 years. Ninety-eight percent received induction chemotherapy. Arterial reconstruction was performed in 17% and concomitant visceral resection in 30%. The R0 resection rate was 87%. Postoperative complications were common (43%) with chyle leak being the most frequent (17%). Length of stay was 8 days, readmission occurred in one-third, and 90-day mortality was 2%. Disease recurrence occurred in 74% during a median follow up of 17.4 months. Median recurrence-free (RFS) and overall survival (OS) were 9 and 25 months, respectively. CONCLUSIONS: Following modern induction paradigms, DP-CAR can be performed with low mortality, manageable morbidity, and excellent rates of margin-negative resection in high-volume settings. The profile of complications of DP-CAR is distinct from pancreaticoduodenectomy and simple distal pancreatectomy. OS and RFS are similar to those undergoing resection of borderline resectable and resectable disease. Improved systemic disease control will likely lead to increasing utilization of aggressive surgical approaches to LAPC.

ABSTRACT

BACKGROUND: Periampullary neuroendocrine tumors (NETs) arise from the duodenum, ampulla, and periampullary pancreas. Duodenal and ampullary NETs are rare and may have distinct biologic behavior from pancreatic NETs (P-NETs). We examined the outcomes of these entities. METHODS: An institutional database was queried for patients undergoing resection for pancreatic head, duodenal, or ampullary NETs from 2000 to 2018. Patients with MEN1 syndrome or follow up less than 12 months were excluded. RESULTS: Three hundred and ten patients were identified. Tumor locations were ampulla (n = 15), duodenum (n = 35) and pancreas (n = 260). Median follow-up and recurrence-free survival (RFS) were 60.9 (interquartile range [IQR]: 34.8-99.3) and 171.7 (IQR: 84.0-NR) months. Clinicopathologic data and survival outcomes were similar for duodenal and ampullary NETs (RFS: p = .347 and overall survival [OS]: p = .246) and were combined into an intestinal subtype (IS) group. There were no differences in OS or RFS when comparing IS-NET and P-NET. On multivariate analysis, tissue of origin was not associated with risk of recurrence. The current American Joint Committee on Cancer staging guidelines, which account for origin tissue, were predictive of outcomes for all subtypes. CONCLUSION: Tissue of origin does not appear to impact long-term outcomes when comparing IS-NETs and P-NETs. The AJCC staging system offers good discriminatory capacity in the context of the tissue type.

ABSTRACT

BACKGROUND: Patient satisfaction is widely reported and impacts satisfaction despite a limited understanding of the clinical and structural determinants. Patients with diverticulitis are admitted to various services, with variable disease severities. They, therefore, represent a unique group to delineate relationships between these factors and satisfaction. We examined the factors that impact hospital satisfaction in patients with diverticulitis. MATERIALS AND METHODS: Patients admitted between 2009 and 2012 were identified using International Classification of Diseases 9th Revision (ICD-9) codes. The primary outcome of patient satisfaction was the Press Ganey Survey overall hospitalization satisfaction question because of a high response rate. This is a precursor survey to the widely available Hospital Consumer Assessment of Healthcare Systems and Providers Survey. There was high concordance between these items. Clinical and structural variables were collected retrospectively. Patients were divided into two groups based on whether they gave the topbox response for the overall hospital rating. RESULTS: Sixty-six patients were identified (56% female, 63 ± 14 years, length of stay: 5 ± 5 d). Seventy-four percent patients rated the hospitalization as topbox. Forty-four percent were admitted to a surgical service, and 21% of all patients underwent an operation. When comparing the topbox to the nontopbox group, demographics and disease severity were similar. Treatment modality, admitting service, and outpatient intravenous antibiotics did not influence patient satisfaction. CONCLUSIONS: Clinical and structural variables did not impact overall hospital satisfaction for patients admitted with diverticulitis. This indicates that less-tangible aspects of in-hospital care may be the primary determinants of hospital satisfaction in this group. Efforts aimed at defining these variables are needed to improve patient satisfaction.

ABSTRACT

BACKGROUND: Endoscopic ultrasound (EUS) is used for pancreatic adenocarcinoma staging and obtaining a tissue diagnosis. The objective was to determine patterns of preoperative EUS and the impact on downstream treatment. METHODS: The Surveillance, Epidemiology, and End Results (SEER) Medicare-linked database was used to identify patients with pancreatic adenocarcinoma. The staging period was the first staging procedure within 6 months of surgery until surgery. Logistic regression was used to determine factors associated with preoperative EUS. The main outcome was EUS in the staging period, with secondary outcomes including number of staging tests and time to surgery. RESULTS: 2782 patients were included, 56% were treated at an academic hospital (n = 1563). 1204 patients underwent EUS (43.3%). The factors most associated with receipt of EUS were: earlier year of diagnosis, SEER area, and a NCI or academic hospital (all p < 0.0001). EUS was associated with a longer time to surgery (17.8 days; p < 0.0001), and a higher number of staging tests (40 tests/100 patients; p < 0.0001). CONCLUSIONS: Factors most associated with receipt of EUS are geographic, temporal, and institutional, rather than clinical/disease factors. EUS is associated with a longer time to surgery and more preoperative testing, and additional study is needed to determine if EUS is overused.

ABSTRACT

BACKGROUND: Air leaks after lobectomy are associated with increased length of stay (LOS) and protracted resource utilization. Portable drainage systems (PDS) allow for outpatient management of air leaks in patients otherwise meeting discharge criteria. We evaluated the safety and cost efficiency of a protocol for outpatient management of air leaks with a PDS. METHODS: We retrospectively assessed patients who underwent lobectomy for non-small-cell lung cancer at our institution between 2004 and 2014. All patients discharged with a PDS for air leak were included in the analysis. The study group was compared to an internally matched cohort of patients undergoing lobectomy for non-small-cell lung cancer managed without the need for outpatient PDS. Study end points included resource utilization, postoperative complications, and readmission. RESULTS: A total of 739 lobectomies were performed during the study period, 73 (10%) patients with air leaks were discharged with a PDS after fulfilling postoperative milestones. Shorter LOS was observed in the study group (3.88 ± 2.4 versus 5.68 ± 5.7 d, P = 0.014) without significant differences in 30-d readmission (11.7% versus 9.0%, P = 0.615). PDS-related complications occurred in 6.8% of study patients (5/73), and 2.7% (2/73) required overnight readmission. PDSs were used for 8.30 ± 4.5 outpatient days. A CMS-based cost analysis predicted an overall savings of $686.72/patient (4.9% of Medicare reimbursement for a major thoracic procedure), associated with significantly fewer hospital days and resources used. CONCLUSIONS: In patients otherwise meeting discharge criteria, outpatient management of air leaks is safe and effective. This strategy is associated with improved efficiency of postoperative care and a modest reduction in hospital costs. This model may be applicable to other thoracic procedures associated with protracted LOS.

ABSTRACT

BACKGROUND: Use of sentinel lymph node biopsy (SLNB) is under-reported by cancer registries' "Scope of Regional Lymph Node Surgery" variable. In 2011, the Surveillance Epidemiology and End Results (SEER) Program recommended against its use to determine extent of axillary surgery, leaving a gap in the utilization of claims data for breast cancer research. The objective was to develop an algorithm using SEER registry and claims data to classify extent of axillary surgery for breast cancer. METHODS: We analyzed data for 24,534 breast cancer patients. CPT codes and number of examined lymph nodes classified the extent of axillary surgery. The final algorithm was validated by comparing the algorithm derived extent of axillary surgery to direct chart review for 100 breast cancer patients treated at our breast center. RESULTS: Using the algorithm, 13% had no axillary surgery, 56% SLNB and 31% axillary lymph node dissection (ALND). SLNB was performed in 77% of node negative patients and ALND in 72% of node positive. In our validation study, concordance between algorithm and direct chart review was 97%. CONCLUSIONS: Given recognized inaccuracies in cancer registries' "Scope of Regional Lymph Node Surgery" variable, these findings have high utility for health services researchers studying breast cancer treatment.

ABSTRACT

BACKGROUND: The management of hepatic hemangiomas remains ill defined. This study sought to investigate the indications, surgical management and outcomes of patients who underwent a resection for hepatic hemangiomas. METHODS: A retrospective review from six major liver centres in the United States identifying patients who underwent surgery for hepatic hemangiomas was performed. Clinico-pathological, treatment and peri-operative data were evaluated. RESULTS: Of the 241patients who underwent a resection, the median age was 46 years [interquartile range (IQR): 39-53] and 85.5% were female. The median hemangioma size was 8.5 cm (IQR: 6-12.1). Surgery was performed for abdominal symptoms (85%), increasing hemangioma size (11.3%) and patient anxiety (3.7%). Life-threatening complications necessitating a hemangioma resection occurred in three patients (1.2%). Clavien Grade 3 or higher complications occurred in 14 patients (5.7%). The 30- and 90-day mortality was 0.8% (n = 2). Of patients with abdominal symptoms, 63.2% reported improvement of symptoms post-operatively. CONCLUSION: A hemangioma resection can be safely performed at high-volume institutions. The primary indication for surgery remains for intractable symptoms. The development of severe complications associated with non-operative management remains a rare event, ultimately challenging the necessity of additional surgical indications for a hemangioma resection.

ABSTRACT

BACKGROUND: Colon cancer outcomes in the United States have improved over the last thirty years. However, there remain significant outcome disparities, especially in rural regions. It is unclear if distance to the treating facility has an independent effect on colon cancer mortality and outcomes. We sought to evaluate whether distance from a treating facility impacts stage at diagnosis and mortality. METHODS: The National Cancer Database (NCDB) was utilized to identify a cohort of adult patients with colon cancer between the years 2013 and 2017 in all regions of the United States. Outcomes measured included colon cancer TNM stage, time to surgery, time to chemotherapy, and overall survival. RESULTS: A total of n = 356,189 patients met inclusion criteria. When controlling for race, education status, insurance status, comorbidities, and income, distance from the treating facility was a significant predictor of stage at presentation with more advanced clinical TNM stage as distance increased (AORs 1.12-1.62, P < .001 for all groups). Longer distance significantly increased the time to surgery (between 5.06 and 14.46 days, P < .001) and overall mortality (HR 1.11-1.28, P < .001). Median survival was 82.4 months for the closest group, versus 75.1 months for the farthest group (P < .001). CONCLUSIONS: Increased distance from the treating facility resulted in a significantly higher stage at presentation, increased time to surgery, and increased mortality. These results suggest that there are significant disparities in access to cancer care for patients who live in rural areas. Targeted interventions by treating facilities are needed to improve screening and timely treatment for rural colon cancer patients.

ABSTRACT

BACKGROUND: Accurate preoperative risk stratification remains elusive. Existing tools are often missing important patient-reported and functional factors. We sought to implement a novel tool, with dynamic functional data and comorbidity variables, to define factors which predict postoperative outcomes. MATERIALS AND METHODS: We expanded a previously validated functional questionnaire to create the Tennessee Preoperative Assessment Tool (TPAT). Unique elements included change in functional status, usual and best activity tolerance, and development of new conditions. The survey was administered to all new patients seen in several surgery clinics from July 2021 to June 2022. RESULTS: A total of 1950 patients completed the survey. Of the completed surveys, 197 patients underwent an elective, inpatient, abdominal surgery and were included in the study. Several patient-reported factors were associated with poor postoperative outcomes. For example, decrease in functional activity in the previous 60 days (n = 50; 25.4%) was a strong predictor of poor postoperative outcomes including readmission (30-day: 8.8% vs .0%; P = .034), wound dehiscence (12.0% vs 3.4%; P = .022), blood transfusion (6.0% vs .0%; P = .003), sepsis (4.0% vs .0%; P = .015), and wound infection (18.0% vs 6.8%; P = .076). DISCUSSION: In this preliminary implementation study, patients undergoing elective, inpatient, abdominal surgery, utilization of a novel, patient-reported survey tool proactively identifies patients at risk of clinically relevant postoperative outcomes. Patient-reported decreased activity in the 60 days prior to surgeon evaluation was associated with several adverse postoperative outcomes. Additionally, this study demonstrates that the TPAT can be seamlessly integrated into the usual clinical workflow and is hypothesis generating for future interventional studies.

ABSTRACT

BACKGROUND: Historically, a positive margin after pancreatectomy for pancreatic ductal adenocarcinoma (PDAC) was associated with decreased survival. In an era when neoadjuvant chemotherapy (NAC) is being used frequently, the prognostic significance of margin status is unclear. STUDY DESIGN: Patients with localized PDAC who received NAC and underwent pancreatectomy from 2011 to 2018 were identified from a single-institution database. Patients with fewer than 2 months of NAC, R2 resection, or fewer than 90 days of follow-up were excluded. A positive margin included tumors within 1 mm of the surgical margin. RESULTS: Four hundred and sixty-eight patients met inclusion criteria. Median age was 65 years and 53% were female. Preoperative clinical staging demonstrated that most had locally advanced (n = 222 [47%]) or borderline resectable (n = 172 [37%]) disease. Median follow-up was 18.5 months (interquartile range 10.6 to 30.0 months). Median duration of NAC was 119 days (interquartile range 87 to 168 days). FOLFIRINOX was first-line therapy for 67%, and 73% received neoadjuvant radiotherapy. Most underwent pancreaticoduodenectomy (69%). Forty percent were node-positive and 80% had an R0 resection. Fifty-six percent received at least 1 cycle of adjuvant therapy. Median overall survival and recurrence-free survival were 22.0 months (95% CI, 19.4 to 25.1 months) and 11.0 months (95% CI, 10.0 to 12.1 months). On multivariate analysis, margin status was not a significant predictor of overall survival or recurrence-free survival. Factors associated with overall survival included clinical stage, duration of NAC, nodal status, histopathologic treatment response score, and receipt of adjuvant chemotherapy. CONCLUSIONS: Microscopic margin positivity is not associated with recurrence and survival in localized PDAC patients resected after treatment with NAC. Aggressive surgical extirpation in high-volume centers should be considered in selected patients after extensive NAC.

ABSTRACT

INTRODUCTION: Robotic pancreaticoduodenectomy is slowly gaining acceptance within pancreatic surgery. Advantages have been demonstrated for robotic surgery in other fields, but robust data for pancreaticoduodenectomy is limited. The aim of this study was to compare the short-term outcomes of robotic pancreaticoduodenectomy (RPD) to open pancreaticoduodenectomy (OPD) and laparoscopic pancreaticoduodenectomy (LPD). METHODS: Patients who underwent a pancreaticoduodenectomy between January 2011 and July 2019 at the Johns Hopkins Hospital were included in this retrospective propensity-matched analysis. The RPD cohort was matched to patients who underwent OPD in a 1:2 fashion and LPD in a 1:1 fashion. Short-term outcomes were analyzed for all three cohorts. RESULTS: In total, 1644 patients were included, of which 96 (5.8%) underwent RPD, 131 (8.0%) LPD, and 1417 (86.2%) OPD. RPD was associated with a decreased incidence of delayed gastric emptying (9.4%) compared to OPD (23.5%; P = 0.006). The median estimated blood loss was significantly less in the RPD cohort (RPD vs OPD, 150 vs 487 mL; P < 0.001, RPD vs LPD, 125 vs 300 mL; P < 0.001). Compared to OPD, the robotic approach was associated with a shorter median length of stay (median 8 vs 9 days; P = 0.014) and a decrease in wound complications (4.2% vs 16.7%; P = 0.002). The incidence of other postoperative complications was comparable between RPD and OPD, and RPD and LPD. CONCLUSION: In the hands of experienced surgeons, RPD may have a modest yet statistically significant reduction in estimated blood loss, postoperative length of stay, wound complications, and delayed gastric emptying comparing to OPD in similar patients.

ABSTRACT

BACKGROUND: Prognostication based on preoperative clinical factors is lacking in patients undergoing cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CRS/HIPEC). This study aims to determine the value of preoperative tumor markers as predictors of progression-free survival (PFS) and overall survival (OS) for patients with peritoneal carcinomatosis from a primary mucinous adenocarcinoma of the appendix (MACA). METHODS: We queried the United States HIPEC Collaborative, a database of patients with peritoneal carcinomatosis treated with CRS/HIPEC at twelve institutions between 2000 and 2017, identifying 409 patients with MACA. Multivariate analysis was used to identify independent predictors of disease progression. Subgroup analysis was conducted to evaluate the impact of tumor grade on the predictive value of tumor markers. RESULTS: CA19-9 [HR 2.44, CI 1.2-3.4] emerged as an independent predictor of PFS while CEA [HR 4.98, CI 1.06-23.46] was independently predictive of OS (p <0.01). Tumor differentiation was the most potent predictor of both PFS (poorly differentiated vs well, [HR 4.5 CI 2.01-9.94]) and OS ([poorly differentiated vs well-differentiated: [HR 13.5, CI 3.16-57.78]), p <0.05. Among patients with combined CA19-9 elevation and poorly differentiated histology, 86% recurred within a year of CRS/HIPEC (p < 0.01). Similarly, the coexistence of CEA elevation and unfavorable histology led to the lowest survival rate at two years [36%, p < 0.01]. CA-125 was not predictive of PFS or OS. CONCLUSION: Elevated preoperative CA19-9 portends worse PFS, while elevated CEA predicts worse OS after CRS/HIPEC in patients with MACA. This study provides additional evidence that CA19-9 and CEA levels should be collected during standard preoperative bloodwork, while CA-125 can likely be omitted. Tumor differentiation, when added to preoperative tumor marker levels, provides powerful prognostic information. Prospective studies are required to confirm this association.

ABSTRACT

OBJECTIVES: Reporting of adverse and near miss events are essential to identify system level targets to improve patient safety. Resident physicians historically report few events despite their role as front-line patient care providers. We sought to evaluate barriers to adverse event reporting in an effort to improve reporting. Our main outcomes were as follows: resident attitudes about event reporting and the frequency of event reporting before and after interventions to address reporting barriers. METHODS: We surveyed first year residents regarding barriers to adverse event reporting and used this input to construct a fishbone diagram listing barriers to reporting. Barriers were addressed, and resident event reporting was compared before and after efforts were made to reduce obstacles to reporting. RESULTS: First year residents (97%) recognized the importance of submitting event reports; however, the majority (85%) had not submitted an event report in the first 6 months of residency. Only 7% of residents specified that they had not witnessed an adverse event in 6 months, whereas one third had witnessed 10 or more events. The main barriers were as follows: lack of knowledge about how to submit events (38%) and lack of time to submit reports (35%). After improving resident education around event reporting and simplifying the reporting process, resident event reporting increased 230% (68 to 154 annual reports, P = 0.025). CONCLUSIONS: We were able to significantly increase resident event reporting by educating residents about adverse events and near misses and addressing the primary barriers to event reporting. Moving forward, we will continue annual resident education about patient safety, focus on improving feedback to residents who submit reports, and empower senior residents to act as role models to junior residents in patient safety initiatives.

ABSTRACT

BACKGROUND: Although provider-derived surgical complication severity grading systems exist, little is known about the patient perspective. OBJECTIVE: To assess patient-rated complication severity and determine concordance with existing grading systems. METHODS: A survey asked general surgery patients to rate the severity of 21 hypothetical postoperative events representing grades 1 to 5 complications from the Accordion Severity Grading System. Concordance with the Accordion scale was examined. Separately, descriptive ratings of 18 brief postoperative events were ranked. RESULTS: One hundred sixty-eight patients returned a mailed survey following their discharge from a general surgery service. Patients rated grade 4 complications highest. Grade 1 complications were rated similarly to grade 5 and higher than grades 2 and 3 (P ≤ .01). Patients rated one event not considered an Accordion scale complication higher than all but grade 4 complications (P < .001). The brief events also did not follow the Accordion scale, other than the grade 6 complication ranking highest. CONCLUSION: Patient-rated complication severity is discordant with provider-derived grading systems, suggesting the need to explore important differences between patient and provider perspectives.

ABSTRACT

BACKGROUND: Prolonged survival of patients after pancreaticoduodenectomy can be associated with late complications due to altered gastrointestinal anatomy. The incidence of gastric cancer is increasingly reported. We set out to examine our experience with gastric cancer as a late complication after pancreaticoduodenectomy with a focus on incidence, risk factors, and outcomes. METHODS: We queried our prospectively collected institutional database for patients that developed gastric cancer after pancreaticoduodenectomy and conducted a systematic review of the literature. RESULTS: Our database revealed 6 patients who developed gastric cancer following pancreaticoduodenectomy, presenting with a mean age of 62.2 years and an even sex distribution. All of those patients underwent pancreaticoduodenectomy for malignant indications with an average time to development of metachronous gastric cancer of 8.3 years. Four patients complained of gastrointestinal discomfort prior to diagnosis of secondary malignancy. All of these cancers were poorly differentiated and were discovered at an advanced T stage (≥ 3). Only half developed at the gastrointestinal anastomosis. Four underwent surgery with a curative intent, and 2 patients are currently alive (mean postgastrectomy survival = 25.5 months). In accordance with previous literature, biliopancreatic reflux from pancreaticoduodenectomy reconstruction, underlying genetic susceptibility, and adjuvant therapy may play a causative role in later development of gastric cancer. CONCLUSION: Long-term survivors after pancreaticoduodenectomy who develop nonspecific gastrointestinal complaints should be evaluated carefully for complications including gastric malignancy. This may serve as an opportunity to intervene on tumors that typically present at an advanced stage and with aggressive histology.

ABSTRACT

BACKGROUND: Patient satisfaction is a patient-centered outcome of particular interest. Previous work has suggested that global measures of satisfaction may not adequately evaluate surgical care, therefore the surgery-specific Consumer Assessment of Healthcare Providers and Systems survey was developed. It remains unclear how traditional outcome measures, such as morbidity, impact patient satisfaction. Our aim was to determine whether National Surgical Quality Improvement Program-defined complications impacted satisfaction with the surgeon as measured by a surgery-specific survey, the surgery-specific Consumer Assessment of Healthcare Providers and Systems survey. METHODS: All patients undergoing a general surgical operation from June 2013-November 2013 were sent the surgery-specific Consumer Assessment of Healthcare Providers and Systems survey after discharge. Retrospective chart review was conducted using the National Surgical Quality Improvement Program variable definitions, and major complications were defined. Data were analyzed as a function of response to the overall surgeon-rating item, and those surgeons rated as the "best possible" or "topbox" were compared with those rated lower. Univariate and logistic regression were used to determine variable importance. RESULTS: A total of 529 patients responded, and 71.5% (378/529) rated the surgeon as topbox. The overall National Surgical Quality Improvement Program complication rate was 14.2% (75/529), with 26.7% of those (20/75) being major complications. On univariate analysis, patients who rated their surgeon more highly were somewhat older (59 vs 54 years: P < .001), more often underwent elective surgery (81% vs 57%: P < .001), and had an increased rate of operation for malignancy (31% vs 17%). Neither the complication rate (total or major) nor the number of complications were associated with satisfaction scores. CONCLUSIONS: When examined on a patient level with surgery-specific measures and outcomes, the presence of complications after an operation does not appear to be associated with overall patient satisfaction with surgeon care. This finding suggests that satisfaction may be an outcome distinct from traditional measures.

ABSTRACT

This article explores how oncology research can be expanded to ensure that research spending results in maximum benefit. The focus has shifted to the value and quality of care, which view cancer care with the perspective of the patient at the center and cover the spectrum of care. Because there is no agreed-upon definition for value in cancer care, we overview various contributions to defining value and quality in oncology. We outline how cancer care costs are measured in the United States and explore outcome measures that have been proposed and implemented to enable us to assess value in oncology.
