Background Although the Barcelona Clinic Liver Cancer (BCLC) staging system has been largely adopted in clinical practice, recent studies have questioned the prognostic stratification of this classification schema, as well as the proposed treatment allocation of patients with a single large tumor. Methods Patients who underwent curative-intent hepatectomy for histologically proven hepatocellular carcinoma (HCC) between 1998 and 2017 were identified using an international multi-institutional database. Overall survival (OS) among patients with BCLC stage 0, A, and B was examined. Patients with a single large tumor were classified as BCLC stage A1 and were independently assessed. Results Among 814 patients, 68 (8.4%) were BCLC-0, 310 (38.1%) were BCLC-A, 279 (34.3%) were BCLC-A1, and 157 (19.3%) were BCLC-B. Five-year OS among patients with BCLC stage 0, A, A1, and B HCC was 86.2%, 69.0%, 56.9%, and 49.9%, respectively ( p  < 0.001). Among patients with very early- and early-stage HCC (BCLC 0, A, and A1), patients with BCLC stage A1 had the worst OS ( p  = 0.0016). No difference in survival was noted among patients undergoing surgery for BCLC stage A1 and B HCC (5-year OS: 56.9% vs. 49.9%; p  = 0.259) even after adjusting for competing factors (hazard ratio 0.83, 95% confidence interval 0.54–1.28; p  = 0.40). Conclusion Prognosis following liver resection among patients with BCLC-A1 HCC was similar to patients presenting with BCLC-B tumors. Surgery provided acceptable long-term outcomes among select patients with BCLC-B HCC. Designation into BCLC stage B should not be considered an a priori contraindication to surgery.

BackgroundIntegration of palliative care services into the surgical treatment plan is important for holistic patient care. We sought to examine the association between patient race/ethnicity and county-level vulnerability relative to patterns of hospice utilization.Patients and MethodsMedicare Standard Analytic Files were used to identify patients undergoing lung, esophageal, pancreatic, colon, or rectal cancer surgery between 2013 and 2017. Data were merged with the Centers for Disease Control and Prevention’s social vulnerability index (SVI). Logistic regression was utilized to identify factors associated with overall hospice utilization among deceased individuals.ResultsA total of 54,256 Medicare beneficiaries underwent lung (n = 16,645, 30.7%), esophageal (n = 1427, 2.6%), pancreatic (n = 6183, 11.4%), colon (n = 26,827, 49.4%), or rectal (n = 3174, 5.9%) cancer resection. Median patient age was 76 years (IQR 71–82 years), and 28,887 patients (53.2%) were male; the majority of individuals were White (91.1%, n = 49,443), while a smaller subset was Black or Latino (racial/ethnic minority: n = 4813, 8.9%). Overall, 35,416 (65.3%) patients utilized hospice services prior to death. Median SVI was 52.8 [interquartile range (IQR) 30.3–71.2]. White patients were more likely to utilize hospice care compared with minority patients (OR 1.24, 95% CI 1.17–1.31, p < 0.001). Unlike White patients, there was reduced odds of hospice utilization (OR 0.97, 95% CI 0.96–0.99) and early hospice initiation (OR 0.94, 95% CI 0.91–0.97) as SVI increased among minority patients.ConclusionsPatients residing in counties with high social vulnerability were less likely to be enrolled in hospice care at the time of death, as well as be less likely to initiate hospice care early. The effects of increasing social vulnerability on hospice utilization were more profound among minority patients.

BackgroundSeveral investigators have advocated for extending the Barcelona Clinic Liver Cancer (BCLC) resection criteria to select patients with BCLC-B and even BCLC-C hepatocellular carcinoma (HCC). The objective of the current study was to define the outcomes and recurrence patterns after resection within and beyond the current resection criteria.Patients and MethodsPatients who underwent resection for HCC within (i.e., BCLC 0/A) and beyond (i.e. BCLC B/C) the current resection criteria between 2005 and 2017 were identified from an international multi-institutional database. Overall survival (OS), disease-free survival (DFS), as well as patterns of recurrence of patients undergoing HCC resection within and beyond the BCLC guidelines were examined.ResultsAmong 756 patients, 602 (79.6%) patients were BCLC 0/A and 154 (20.4%) were BCLC B/C. Recurrences were mostly intrahepatic (within BCLC: 74.3% versus beyond BCLC: 70.8%, p = 0.80), with BCLC B/C patients more often having multiple tumors at relapse (69.6% versus 49.4%, p = 0.001) and higher rates of early (< 2 years) recurrence (88.0% versus 75.5%, p = 0.011). During the first postoperative year, annual recurrence was 38.3% and 21.3% among BCLC B/C and BCLC 0/A patients, respectively; 5-year OS among BCLC 0/A and BCLC B/C patients was 76.9% versus 51.6% (p = 0.003). On multivariable analysis, only a-fetoprotein (AFP) > 400 ng/mL (HR = 1.84, 95% CI 1.07–3.15) and R1 resection (HR = 2.36, 95% CI 1.32–4.23) were associated with higher risk of recurrence among BCLC B/C patients.ConclusionsSurgery can provide acceptable outcomes among select patients with BCLC B/C HCC. The data emphasize the need to further refine the BCLC treatment algorithm as well as highlight the need for surveillance protocols with a particular focus on the liver, especially for patients undergoing resection outside the BCLC criteria.

BackgroundThe impact of depression on utilization of post-discharge care and overall episode of care expenditures remains poorly defined. We sought to define the impact of depression on postoperative outcomes, including discharge disposition, as well as overall expenditures associated with the global episode of surgical care.MethodThe Medicare 100% Standard Analytic Files were used to identify patients undergoing resection for esophageal, colon, rectal, pancreatic, and liver cancer between 2013 and 2017. The impact of depression on inpatient outcomes, as well as home health care and skilled nursing facilities utilization and expenditures, was analyzed.ResultsAmong 113,263 patients, 14,618 (12.9%) individuals had depression. Patients with depression were more likely to experience postoperative complications (odds ratio [OR] 1.36, 95% confidence interval [CI] 1.31–1.42), extended length of stay (LOS) (OR 1.41, 95% CI 1.36–1.47), readmission within 90 days (OR 1.20, 95% CI 1.14–1.25), as well as 90-day mortality (OR 1.35, 95% CI 1.27–1.42) (all p < 0.05). In turn, the proportion of patients who achieved a textbook outcome following cancer surgery was lower among patients with depression (no depression: 53.3% vs. depression: 45.3%; OR 0.70, 95% CI 0.68–0.73). Patients with a preexisting diagnosis of depression had higher odds of additional post-discharge expenditures compared with individuals without a diagnosis of depression (OR 1.42; 95% CI 1.35–1.50); patients with a preexisting diagnosis of depression ($10,500, IQR $3,200–$22,500) had higher median post-discharge expenditures versus patients without depression ($6600, IQR $2100–$17,400) (p < 0.001). On multivariable analysis, after controlling for other factors, depression remained associated with a 19.0% (95% confidence interval [CI] 15.7–22.3%) increase in post-discharge expenditures.ConclusionsPatients with depression undergoing resection for cancer had worse in-patient outcomes and were less likely to achieve a TO. Patients with depression were more likely to require post-discharge care and had higher post-discharge expenditures.

Introduction Intrahepatic cholangiocarcinoma (ICC) remains an uncommon disease with a rising incidence worldwide. We sought to identify trends in therapeutic approaches and differences in patient outcomes based on facility types. Methods Between January 1, 2004, and December 31, 2015, a total of 27,120 patients with histologic diagnosis of ICC were identified in the National Cancer Database and were enrolled in this study. Results The incidence of ICC patients increased from 1194 in 2004 to 3821 in 2015 with an average annual increase of 4.16% ( p  < 0.001). Median survival of the cohort improved over the last 6 years of the study period (2004–2009: 8.05 months vs. 2010–2015: 9.49 months; p  < 0.001). Among surgical patients ( n  = 5943, 21.9%), the incidence of R0 resection, lymphadenectomy and harvest of ≥6 lymph nodes increased over time ( p  < 0.001). Positive surgical margins (referent R0: R1, HR 1.49, 95% CI 1.24–1.79, p  < 0.001) and treatment at community cancer centers (referent academic centers; HR 1.24, 95% CI 1.04–1.49, p  = 0.023) were associated with a worse prognosis. Patients treated at academic centers had higher rates of R0 resection (72.4% vs. 67.7%; p  = 0.006) and lymphadenectomy (55.6% vs. 49.5%, p  = 0.009) versus community cancer centers. Overall survival was also better at academic versus community cancer programs (median OS: 11 months versus 6 months, respectively; p  < 0.001). Conclusions The incidence of ICC has increased over the last 12 years in the USA with a moderate improvement in survival over time. Treatment at academic cancer centers was associated with higher R0 resection and lymphadenectomy rates, as well as improved OS for patients with ICC.

Introduction A person’s community, or lived environment, may play an important role in achieving optimal health outcomes. The objective of the current study was to assess the association of county-level vulnerability with the probability of having a non-elective colon resection. We hypothesized that individuals from areas with a high social vulnerability would be at greater risk of non-elective colon resection compared with patients from low social vulnerability areas. Methods Patients aged 65–99 who underwent a colon resection for a primary diagnosis of either diverticulitis ( n = 11,812) or colon cancer ( n = 33,312) were identified in Medicare Part A and Part B for years 2016–2017. Logistic regression analysis was used to evaluate differences in probability of undergoing an elective versus non-elective operation from counties relative to county-level social vulnerability index (SVI). Secondary outcomes included postoperative complications, mortality, readmission, and index hospitalization expenditure. Results Among 45,124 patients, 11,812 (26.2%) underwent a colon resection for diverticulitis, while 33,312 (73.8%) had a resection for colon cancer; 31,012 (68.7%) patients had an elective procedure (diverticulitis n = 7291 (61.7%) vs. cancer n = 23,721 (71.2%)), while 14,112 (31.3%) had an emergent operation (diverticulitis n = 4521 (38.3%) vs. cancer n = 9591 (28.8%)). Patients with a high SVI were more likely to undergo an emergent colon operation compared with low SVI patients (43.7% vs. 40.4%) ( p < 0.001). The association of high SVI with increased risk of an emergent colon operation was similar among patients with diverticulitis (emergent: low SVI 37.2% vs. high SVI 40.4%) or colon cancer (emergent: low SVI 26.0% vs. high SVI 29.9%) (both p < 0.05). On multivariable analyses, risk-adjusted probability of undergoing an urgent/emergent operation remained associated with SVI ( p < 0.05). Conclusion Patients residing in vulnerable communities characterized by a high SVI were more likely to undergo a non-elective colon resection for either diverticulitis or colon cancer. Patients from high SVI areas had a higher risk of postoperative complications, as well as index hospitalization expenditures; however, there were no differences in mortality or readmission rates.

BackgroundPatients can experience barriers and disparities to access high-quality cancer care. This study sought to characterize receipt of surgery and chemotherapy among Medicare beneficiaries with a diagnosis of early-stage pancreatic adenocarcinoma cancer (PDAC) relative to race/ethnicity and social vulnerability.MethodsThe Surveillance, Epidemiology, and End Results (SEER)-Medicare database was used to identify patients with a diagnosis of early-stage (stage 1 or 2) PDAC between 2004 and 2016. Data were merged with the CDC’s Social Vulnerability Index (SVI) at the beneficiary’s county of residence. Multivariable, mixed-effects logistic regression was used to assess the association of SVI with resection.ResultsAmong 15,931 older Medicare beneficiaries with early-stage PDAC (median age, 77 years; interquartile range [IQR], 71–82 years), the majority was White (n = 12,737, 80.0 %), whereas a smaller subset was Black or Latino (n = 3194, 20.0 %) A minority of patients was more likely to live in highly vulnerable communities (low SVI: white [90.5 %] vs minority [9.5 %] vs high SVI: white [71.9 %] vs minority [28.1 %]; p < 0.001). Use of resection for early-stage PDAC was lowest among the patients who resided in high-SVI areas (low [38.0 %] vs average [34.3 %] vs high [31.9 %]; p < 0.001). The minority patients were less likely to undergo resection than the White patients (no resection: white [64.1 %] vs minority [70.7 %]; p < 0.001). The median SVI was higher among the patients who underwent resection (57.6; IQR, 36.0–81.0) than among those who did not (60.4; IQR, 41.9–84.3), and increased SVI resulted in a decline in the likelihood of resection (SVI trend: OR, 0.98; 95 % confidence interval [CI], 0.97–1.00), especially among the minority patients. Minority patients from high-SVI counties had markedly lower odds of preoperative chemotherapy than minority patients from a low-SVI neighborhood (OR, 0.62; 95 % CI, 0.52–0.73).ConclusionsOlder Medicare beneficiaries with early-stage PDAC residing in counties with higher social vulnerability had lower odds of undergoing pancreatic resection, which was more pronounced among minority versus older White Medicare beneficiaries.

Background Surgical resection is the only potentially curative treatment for patients with colorectal, liver, and pancreatic cancers. Although these procedures are performed with low mortality, rates of complications remain relatively high following hepatopancreatic and colorectal surgery. Methods The American College of Surgeons (ACS) National Surgical Quality Improvement Program was utilized to identify patients undergoing liver, pancreatic and colorectal surgery from 2014 to 2016. Decision tree models were utilized to predict the occurrence of any complication, as well as specific complications. To assess the variability of the performance of the classification trees, bootstrapping was performed on 50% of the sample. Results Algorithms were derived from a total of 15,657 patients who met inclusion criteria. The algorithm had a good predictive ability for the occurrence of any complication, with a C -statistic of 0.74, outperforming the ASA ( C -statistic 0.58) and ACS-Surgical Risk Calculator ( C -statistic 0.71). The algorithm was able to predict with high accuracy thirteen out of the seventeen complications analyzed. The best performance was in the prediction of stroke ( C -statistic 0.98), followed by wound dehiscence, cardiac arrest, and progressive renal failure (all C -statistic 0.96). The algorithm had a good predictive ability for superficial SSI ( C -statistic 0.76), organ space SSI ( C -statistic 0.76), sepsis ( C -statistic 0.79), and bleeding requiring transfusion ( C -statistic 0.79). Conclusion Machine learning was used to develop an algorithm that accurately predicted patient risk of developing complications following liver, pancreatic, or colorectal surgery. The algorithm had very good predictive ability to predict specific complications and demonstrated superiority over other established methods.

Introduction Although a positive surgical margin is a known prognostic factor for recurrence, the optimal surgical margin width in the context of an R0 resection for early-stage hepatocellular carcinoma (HCC) is still debated. The aim of the current study was to examine the impact of wide ( >  1 cm) versus narrow (< 1 cm) surgical margin status on the incidence and recurrence patterns among patients with T1 HCC undergoing an R0 hepatectomy. Methods Between 1998 and 2017, patients with T1 HCC who underwent R0 hepatectomy for stage T1 HCC were identified using an international multi-institutional database. Recurrence-free survival (RFS) was estimated, and recurrence patterns were examined based on whether patients had a wide versus narrow resection margins. Results Among 404 patients, median patient age was 66 years (IQR: 58–73). Most patients ( n  = 326, 80.7%) had surgical margin < 1 cm, while 78 (19.3%) patients had a >  1 cm margin. The majority of patients had early recurrences (< 24 months) in both margin width groups (< 1 cm: 70.3% vs >  1 cm: 85.7%, p  = 0.141); recurrence site was mostly intrahepatic (< 1 cm: 77% vs >  1 cm: 61.9%, p  = 0.169). The 1-, 3-, and 5-year RFS among patients with margin < 1 cm were 77%, 48.9%, and 35.3% versus 81.7%, 65.8%, and 60.7% for patients with margin >  1 cm, respectively ( p  = 0.02). Among patients undergoing anatomic resection, resection margin did not impact RFS (3-year RFS: < 1 cm: 49.2% vs >  1 cm: 58.9%, p  = 0.169), whereas in the non-anatomic resection group, margin width >  1 cm was associated with a better 3-year RFS compared to margin < 1 cm (86.7% vs 47.3%, p  = 0.017). On multivariable analysis, margin >  1 cm remained protective against recurrence (HR = 0.50, 95%CI 0.28–0.89), whereas Child-Pugh B (HR = 2.13, 95%CI 1.09–4.15), AFP >  20 ng/mL (HR = 1.71, 95%CI 1.18–2.48), and presence of microscopic lymphovascular invasion (HR = 1.48, 95%CI 1.01–2.18) were associated with a higher hazard of recurrence. Conclusion Resection margins >  1 cm predicted better RFS among patients undergoing R0 hepatectomy for T1 HCC, especially small (< 5 cm) HCC. Although resection margin width did not influence outcomes after anatomic resection, wider margins were more important among patients undergoing non-anatomic liver resections.

Background The impact of tumor burden score (TBS) on conditional survival (CS) among patients undergoing curative-intent resection of hepatocellular carcinoma (HCC) has not been examined to date. Methods Patients who underwent liver resection of HCC between 2000 and 2017 were identified from a multi-institutional database. The impact of TBS and other clinicopathologic factors on 3-year conditional survival (CS 3 ) was examined. Results Among 1,040 patients, 263 (25.3%) patients had low TBS, 668 (64.2%) had medium TBS and 109 (10.5%) had high TBS. TBS was strongly associated with OS; 5-year OS was 39.0% among patients with high TBS compared with 61.1% and 79.4% among patients with medium and low TBS, respectively ( p  < 0.001). While actuarial survival decreased as time elapsed from resection, CS increased over time irrespective of TBS. The largest differences between 3-year actuarial survival and CS 3 were noted among patients with high TBS (5-years postoperatively; CS 3 : 78.7% vs. 3-year actuarial survival: 30.7%). The effect of adverse clinicopathologic factors including high TBS, poor/undifferentiated tumor grade, microvascular invasion, liver capsule involvement, and positive margins on prognosis decreased over time. Conclusions CS rates among patients who underwent resection for HCC increased as patients survived additional years, irrespective of TBS. CS estimates can be used to provide important dynamic information relative to the changing survival probability after resection of HCC.
