Disparities in Survival and NCCN Guideline-Concordant Care in Patients With Extremity Soft Tissue Sarcoma.

BACKGROUND: Based on the NCCN Guidelines for Soft Tissue Sarcoma (STS), treatment of extremity STS (ESTS) includes radiation therapy (RT) and surgical resection for tumors that are high-grade and >5 cm. ​​The aim of this study was to describe the association between neighborhood socioeconomic status (nSES), concordance with NCCN Guidelines recommendations, and outcomes in patients with ESTS. METHODS: Patients with ESTS diagnosed from 2006 through 2018 were identified in SEER registries. The analytic cohort was restricted to patients with high-grade tumors >5 cm without nodal or distant metastases who received limb-sparing surgery. Patient demographics and tumor characteristics associated with receipt of RT were analyzed using adjusted regression analyses. Kaplan-Meier curves and adjusted accelerated failure time models were used to examine disparities in cancer-specific survival. RESULTS: Of 2,249 patients, 29.0% (n=648) received neoadjuvant RT, 49.7% (n=1,111) received adjuvant or intraoperative RT, and 21.3% (n=476) did not receive RT. In adjusted analyses, lower nSES was associated with lower likelihood of receiving RT (odds ratio, 0.70 [95% CI, 0.57-0.87]; P<.001). Low nSES was associated with worse cancer-specific survival (hazard ratio, 1.19 [95% CI, 1.01-1.40]; P=.04). Race and ethnicity were not significant predictors of receipt of RT or cancer-specific survival in the fully adjusted models. CONCLUSIONS: Patients from lower nSES areas were less likely to receive NCCN Guideline-recommended RT for their ESTS and had worse cancer-specific survival. Efforts to better define and resolve disparities in the treatment and survival of patients with ESTS are warranted.

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.

Implementation of Hepatic Artery Infusion Pump Therapy: Real-World Single-Center Experience.

BACKGROUND AND OBJECTIVES: Hepatic artery infusion pump (HAIP) therapy is an available option at highly specialized centers to treat unresectable liver tumors (e.g., colorectal liver metastases [CRLM]). This study describes the safety and outcomes of HAIP program implementation at an academic-based cancer center. METHODS: Patients who underwent HAIP placement (2021-2023) were included. Categorical and continuous variables were compared using Chi-square and Kruska-Wallis tests, respectively. Survival and variables associated with survival were calculated using the Kaplan-Meier method and Cox proportional hazards model, respectively. RESULTS: Of the 26 HAIP procedures for unresectable CRLM, four were done as adjuvant therapy. Median duration of HAIP therapy was 9.2 months and four patients subsequently underwent hepatectomy. Complication rate was 37.5%, with biliary complication rate of 23.1%. Median overall survival (OS) from date of diagnosis was 55.2 months. Concurrent primary tumor resection was associated with inferior OS (p = 0.030). Multivariable regression did not identify independent predictors of OS. Progression-free survival from time of HAIP placement was 7.8 months. CONCLUSIONS: HAIP placement was technically successful in most patients with an acceptable complication rate. Survival outcomes were comparable with those described in the literature for HAIP therapy in combination with systemic therapy. The significant difference in outcomes for those with concurrent colectomy warrants further investigation.

Trans-arterial embolization versus chemoembolization for neuroendocrine liver metastases: a propensity matched analysis.

INTRODUCTION: Locoregional therapies are a mainstay of treatment for patients with neuroendocrine liver metastases (NELM), yet the optimal transarterial approach remains undefined and recent studies have raised concern over the safety of transarterial chemoembolization (TACE). METHODS: Patients with NELM who underwent TACE or transarterial embolization (TAE) at a single institution between 2000-2022 were retrospectively reviewed. Propensity score matching (PSM) controlling for age, sex, bilateral disease, tumor size, lobar embolization, grade, and extrahepatic disease was utilized to compare short- and long-term outcomes. RESULTS: Among 412 patients with NELM, 329 underwent TACE and 83 TAE. Mean age was 60.7 ± 11.1 years. Patients primarily presented with synchronous (69.2%), bilateral (84.2%), and G1 disease (48.8%) and underwent staged procedures (55.8%). Following PSM, TACE was associated with slightly worse post-procedure laboratory values, but no difference in complications compared to TAE (23.3%vs29.3%, p = 0.247). TACE was associated with improved mean PFS (21.8vs10.7 months, p = 0.002), but no difference in radiographic size, chromogranin level, or median overall survival (50.0 months vs not met, p = 0.833). CONCLUSION: Among patients with NELM, TACE was associated with similar short-term outcomes and improved PFS, but no difference in OS compared to TAE. These findings highlight the need for additional research on the optimal locoregional therapy for NELM.

Annals of Surgical Oncology Practice Guidelines Series: Management of Primary Liver and Biliary Tract Cancers.

Primary cancers of the liver and biliary tract are rare and aggressive tumors that often present with locally advanced or metastatic disease. For patients with localized disease amenable to resection, surgery typically offers the best chance at curative-intent therapy. Unfortunately, the incidence of recurrence even after curative-intent surgery remains high. In turn, patients with hepatobiliary cancers commonly require multimodality therapy including a combination of resection, systemic therapy (i.e., targeted therapy, cytotoxic chemotherapy, immunotherapy), and/or loco-regional therapies. With advancements in the field, it is crucial for surgical oncologists to remain updated on the latest guidelines and recommendations for surgical management and optimal patient selection. Given the complex and evolving nature of treatment, this report highlights the latest practice guidelines for the surgical management of hepatobiliary cancers.

Potential Role for Observation in Small Solid Pseudopapillary Neoplasm (SPN).

BACKGROUND: Solid pseudopapillary neoplasms (SPN) are rare tumors of the pancreas, typically affecting young women. Resection is the mainstay of treatment but is associated with significant morbidity and potential mortality. We explore the idea that small, localized SPN could be safely observed. METHODS: This retrospective review of the Pancreas National Cancer Database from 2004 to 2018 identified SPN via histology code 8452. RESULTS: A total of 994 SPNs were identified. Mean age was 36.8 ± 0.5 years, 84.9% (n = 844) were female, and most had a Charlson-Deyo Comorbidity Coefficient (CDCC) of 0-1 (96.6%, n = 960). Patients were most often staged clinically as cT2 (69.5%, n = 457) followed by cT3 (17.6%, n = 116), cT1 (11.2%, n = 74), and cT4 (1.7%, n = 11). Clinical lymph node and distant metastasis rates were 3.0 and 4.0%, respectively. Surgical resection was performed in 96.6% of patients (n = 960), most commonly partial pancreatectomy (44.3%) followed by pancreatoduodenectomy (31.3%) and total pancreatectomy (8.1%). In patients clinically staged as node (N0) and distant metastasis (M0) negative, occult pathologic lymph node involvement was found in 0% (n = 28) of patients with stage cT1 and 0.5% (n = 185) of patients with cT2 disease. The risk of occult nodal metastasis significantly increased to 8.9% (n = 61) for patients with cT3 disease. The risk further increased to 50% (n = 2) in patients with cT4 disease. CONCLUSIONS: Herein, the specificity of excluding nodal involvement clinically is 99.5% in tumors ≤ 4 cm and 100% in tumors ≤ 2 cm. Therefore, there may be a role for close observation in patients with cT1N0 lesions to mitigate morbidity from major pancreatic resection.

Disparities in NCCN Guideline-Compliant Care for Patients with Early-Stage Pancreatic Adenocarcinoma at Minority-Serving versus Non-Minority-Serving Hospitals.

BACKGROUND: Racial/ethnic disparities in pancreatic adenocarcinoma (PDAC) outcomes may relate to receipt of National Comprehensive Cancer Network (NCCN) guideline-compliant care. We assessed the association between treatment at minority-serving hospitals (MSH) and receipt of NCCN-compliant care. PATIENTS AND METHODS: Patients who underwent resection of early-stage PDAC between 2006 and 2019 were identified from the National Cancer Database (NCDB). MSH was defined as the top decile of facilities treating minority ethnicities (Black and/or Hispanic). Factors associated with receipt of NCCN-compliant care and its impact on overall survival (OS) were assessed. RESULTS: Among 44,873 patients who underwent resection of PDAC, most were treated at non-MSH (n = 42,571, 94.9%), while a smaller subset were treated at MSH (n = 2302, 5.1%). Patients treated at MSH were more likely to be at a younger median age (MSH 66 years versus non-MSH 67 years), Black or Hispanic (MSH 58.4% versus non-MSH 12.0%), and not insured (MSH 7.8% versus non-MSH 1.6%). While 71.7% (n = 31,182) of patients were compliant with NCCN care, guideline-compliant care was lower at MSH (MSH 62.5% versus non-MSH 72.2%). On multivariable analysis, receiving care at MSH was associated with not receiving guideline-compliant care [odds ratio (OR) 0.63, 95% confidence interval (CI) 0.53-0.74]. At non-MSH, non-white patients had lower odds of receiving guideline-compliant PDCA care (OR 0.85, 95% CI 0.78-0.91). Failure to comply was associated with worse overall survival (OS) [hazard ratio (HR) 1.50, 95% CI 1.46-1.54, all p < 0.001]. CONCLUSIONS: Patients with PDAC treated at MSH and minorities treated at non-MSH were less likely to receive NCCN-compliant care. Failure to comply with guideline-based PDAC treatment was associated with worse OS.

Trends and Variations in Drain Use Following Pancreatoduodenectomy: Is Early Drain Removal Becoming More Common?

BACKGROUND: Although previous studies have noted the potential benefit of early drain removal (EDR) after pancreatoduodenectomy (PD), there is a paucity of data on the timing of drain removal utilizing a national database that reflect the "real world" setting. Given the ongoing controversy related to PD drain use and management, we sought to define trends in drain use among a large national cohort, as well as identify factors associated with EDR following PD. METHODS: The ACS NSQIP targeted pancreatectomy database was used to identify patients who underwent PD between 2014 and 2020. The trend in proportion of patients with EDR (removal ≤ POD3) as well as predictors of EDR were assessed. Risk-adjusted postoperative outcomes were evaluated by multivariable regression analysis. RESULTS: Among 14,356 patients, 16.2% of patients (N = 2324) experienced EDR, and the proportion of patients with EDR increased by 68% over the study period (2014: 10.9% vs. 2020: 18.3%, p < 0.001). Higher drain fluid amylase on POD1-3 [LogWorth (LW) = 44.3], operative time (LW = 33.2), and use of minimally invasive surgery (LW = 14.0) were associated with EDR. Additionally, EDR was associated with decreased risk of overall and serious morbidity, PD-related morbidity (e.g., pancreatic fistula), reoperation, prolonged length of stay and readmission (all p < 0.05). CONCLUSIONS: Routine drain placement remains a common practice among most surgeons. EDR following PD increased over time was associated with lower post-operative complications and shorter LOS. Despite evidence that EDR was safe and may even be associated with lower complications, only 1 in 6 patients were managed with EDR.

Updates and Expert Opinions on Liver Transplantation for Gastrointestinal Malignancies.

Transplant oncology is a relatively new field in which transplantation is used to treat patients who would otherwise be unresectable. New anticancer treatment paradigms using tumor and transplant immunology and cancer immunogenomics are emerging. In turn, liver transplantation (LT) has become a potential therapy for certain patients with colorectal cancer (CRC) with liver metastasis, hepatocellular (HCC), cholangiocarcinoma (CCA), and metastatic neuroendocrine tumor (NET) of the liver. Although there are established criteria for LT in HCC, evidence regarding LT as a treatment modality for certain gastrointestinal malignancies is still debated. The aim of this review is to highlight updates in the role of LT for certain malignancies, including HCC, metastatic CRC, hilar CCA, and neuroendocrine tumor (NET), as well as contextualize LT use and discuss controversies in transplant oncology.

Surgical debulking is associated with improved survival for patients with neuroendocrine liver metastases of unknown primary.

BACKGROUND: Resection of neuroendocrine tumors (NET) with surgical debulking of liver metastasis (NETLM) is associated with improved survival. In patients with an unknown primary (UP-NETLM), the effects of debulking remains unclear. METHODS: The National Cancer Database (2004-2016) was queried for patients with small intestine (SI) and pancreas (P) NETLMs. If the liver was listed as the primary site, the patient's disease was classified as UP-NETLM. RESULTS: Patients with UP-NETLM, SI-NETLM, and P-NETLM who were managed non-operatively demonstrated a significant difference in 5-year overall survival (OS) (21.5% vs. 39.2% vs. 17.1%; p < 0.0001). OS in patients who underwent debulking was higher (63.7% vs. 73.2% vs. 54.2%). Patients with UP-NETLMs who underwent debulking had similar OS to patient with SI-NETLM (p = 0.051), but significantly higher OS, depending on tumor differentiation, compared to patients with P-NETLMs. If well-differentiated, surgery for UP-NETLMs was associated with a higher rate of OS (p = 0.009), while no difference was observed if moderately (p = 0.209) or poorly/undifferentiated (p = 0.633). P-NETLMs were associated with worse OS (p < 0.001) on multivariate analysis. DISCUSSION: Debulking in patients with UP-NETLMs was associated with similar OS compared to patients with SI-NETLMs and better or similar OS compared to patient with P-NETLMs.

Advances in Targeted Immunotherapy for Hepatobiliary Cancers.

Cancer of the hepatobiliary system can be divided into primary liver cancer and biliary tract cancer (BTC), which includes hepatocellular carcinoma (HCC), cholangiocarcinoma (CCA), and gallbladder cancer (GBC). These aggressive cancers often present at an advanced stage or among patients with poorly preserved liver function. The primary treatment for HCC and BTC when diagnosed early is surgical resection, but given the high rate of recurrence and often advanced stage at diagnosis, many patients will require systemic therapy. Unfortunately, even with systemic therapy, long-term survival is poor. The immune system plays an important role in preventing cancer progression. The unique immune environment of the liver and subsequent alterations to the immune microenvironment by tumor cells to create a favorable microenvironment plays a key role in the progression of HCC and BTC. Due to the paucity of effective systemic therapies and distinctive immune environment of the liver, research and clinical trials are investigating the use of immunotherapy in HCC and BTC. This review will focus on current immunotherapies and emerging data for the treatment of HCC and BTC.

Ampullary Neuroendocrine Tumors: Insight into a Rare Histology.

BACKGROUND: Ampullary neuroendocrine tumors (NETs) make up < 1% of all gastroenteropancreatic NETs, and information is limited to case series. This study compares patients with ampullary, duodenal, and pancreatic head NETs. METHODS: The National Cancer Database (2004-2016) was queried for patients with ampullary, duodenal, and pancreatic head NETs. Survival was evaluated using Kaplan-Meier analysis and Cox regression. RESULTS: Overall, 872, 9692, and 6561 patients were identified with ampullary, duodenal, and pancreatic head NETs, respectively. Patients with ampullary NETs had more grade 3 tumors (n = 149, 17%) than patients with duodenal (n = 197, 2%) or pancreatic head (n = 740, 11%) NETs. Patients with ampullary NETs had more positive lymph nodes (n = 297, 34%) than patients with duodenal (n = 950, 10%) or pancreatic head (n = 1513, 23%) NETs. On multivariable analysis for patients with ampullary NETs, age (hazard ratio [HR] 1.03, p < 0.0001), Charlson-Deyo score of 2 (HR 2.3, p = 0.001) or ≥3 (HR 2.9, p = 0.013), grade 2 (HR 1.9, p = 0.007) or grade 3 tumors (HR 4.0, p < 0.0001), and metastatic disease (HR 2.0, p = 0.001) were associated with decreased survival. At 5 years, the overall survival (OS) for patients with ampullary, duodenal, and pancreatic head NETs was 59%, 71%, and 50%, respectively (p < 0.0001), whereas the 5-year OS for patients with ampullary, duodenal, and pancreatic head NETs who underwent surgery was 62%, 78%, and 76%, respectively (p < 0.0001). CONCLUSIONS: Ampullary NETs were more likely to present with high-grade tumors and lymph node metastases. Based on the clinicopathologic and survival data, ampullary NETs have a unique underlying biology compared with duodenal and pancreatic head NETs.

Elevated Serum α-Fetoprotein is Associated with Abbreviated Survival for Patients with Fibrolamellar Hepatocellular Carcinoma Who Undergo a Curative Resection.

BACKGROUND: Fibrolamellar hepatocellular carcinoma (FLC) is a rare variant of hepatocellular carcinoma (HCC), with most clinical data stemming from single-institution series. The variability in the literature lends support for analysis using a large national dataset. In doing so, we sought to (1) define the characteristics and outcomes of patients with FLC; (2) determine factors associated with survival in patients undergoing resection; and (3) compare the overall survival (OS) of patients with FLC with a matched group of patients with HCC. METHODS: The National Cancer Database was queried for patients with FLC, and their clinicopathologic features were recorded. Univariate and multivariate analyses were performed to delineate factors associated with survival. RESULTS: Between 2004 and 2015, 496 patients were diagnosed with FLC, 229 of whom underwent a curative resection. The median OS for patients with FLC undergoing curative resection was 78.5 months. Factors associated with abbreviated OS in this surgical cohort include multiple tumors [hazard ratio (HR) 3.15, p = 0.025], positive regional lymph nodes (HR 2.83, p = 0.023), and elevated serum α-fetoprotein (AFP; HR 2.81, p = 0.034). When the OS of patients with FLC was compared with a matched group of patients with HCC, no difference was detected (p = 0.748); however, patients with FLC and elevated AFP had abbreviated OS compared with patients with HCC and elevated AFP (43 vs. 82 months, p ≤ 0.001). CONCLUSIONS: Elevations in serum AFP occur more frequently than previously documented for patients with FLC and are associated with abbreviated OS. AFP levels may help guide the decision for operative intervention in patients with FLC.

Gallbladder squamous cell carcinoma: An analysis of 1084 cases from the National Cancer Database.

BACKGROUND/OBJECTIVES: Gallbladder squamous cell carcinoma (SCC) is an uncommon malignancy whose rarity has made it particularly challenging to study. We utilized a national database to shed light on the clinicopathologic characteristics, management patterns, and survival associated with these tumors. METHODS: Patients with gallbladder SCC were identified in the National Cancer Database. Clinicopathologic and treatment characteristics were recorded and compared with adenocarcinoma for context. Univariate and multivariable survival analyses were completed for patients who underwent resection. RESULTS: Overall, 1084 patients with SCC and 23 958 patients with adenocarcinoma were identified. Compared with those with adenocarcinoma, patients with SCC had higher grade tumors (P < .001) and were diagnosed at a later stage (P < .001). Patients with SCC were more likely to undergo radical cholecystectomy (17% vs 9%; P < .001), but had a higher rate of margin positivity (36% vs 29%; P < .001). SCC histology was associated with worse survival compared with adenocarcinoma, even after adjusting for R0 resections (13 vs 29 months; P < .001). On multivariable analysis, SCC histology was independently associated with abbreviated survival (P = .003). CONCLUSIONS: Gallbladder SCCs are aggressive cancers that often present at an advanced stage. Complete surgical extirpation should be pursued when feasible. However, prognosis is worse than that of adenocarcinoma, even after R0 resection.

Surgical Resection of Pheochromocytomas and Paragangliomas is Associated with Lower Cholesterol Levels.

BACKGROUND: Catecholamine excess in patients with pheochromocytomas or paragangliomas (PPGLs) can lead to hypertension, diabetes and hyperlipidemia. The aim was to investigate the prevalence of hyperlipidemia and the effect of surgical resection. METHODS: One hundred and thirty-two patients with PPGLs underwent an operation at the National Institutes of Health from 2009 to 2016, of which 54 patients met the inclusion criteria. Clinical demographics, BMI, genetic mutations, tumor size, perioperative catecholamine levels and perioperative lipid panels were retrospectively reviewed. Spearman correlation between catecholamines and lipid levels was evaluated. Paired Wilcoxon and paired t test were used to analyze differences in pre- and postoperative lipid levels. RESULTS: Preoperatively, 51 patients (94.4%) had elevated catecholamines, thirteen (24.1%) had elevated total cholesterol (TC) (>200 mg/dL), nine (16.6%) had elevated LDL (>130 mg/dL) and ten (18.5%) had elevated triglycerides (>150 mg/dL). Serum and urinary metanephrine levels were positively associated with TC (r = 0.2792, p = 0.0372 and r = 0.4146, p = 0.0031, respectively) and LDL levels (r = 0.2977, p = 0.0259 and r = 0.4434, p = 0.0014, respectively). Mean TC decreased from 176.4 to 166.3 mg/dL (p = 0.0064) and mean HDL decreased from 56.7 to 53.2 mg/dL (p = 0.0253) after PPGL resection (median 3.1 months (range 1.3-50.2) between lipid panels). Most patients with elevated TC (76.9%) had improvement with mean TC decreasing from 225 to 200.2 mg/dL (p = 0.0230). Of patients with elevated LDL, 66.7% had improvement with mean LDL decreasing from 149 to 131.1 mg/dL (p = 0.0313). CONCLUSIONS: The prevalence of hyperlipidemia in patients with PPGLs is 46%. Future prospective studies are needed to determine whether surgical resection improves TC and/or LDL levels.

Tumor grade may be used to select patients with multifocal hepatocellular carcinoma for resection.

BACKGROUND: While resection is a recommended treatment for patients with stage 1 hepatocellular carcinoma (HCC), it remains controversial for multifocal disease. We sought to identify patients with multifocal HCC with survival after resection similar to patients with clinical stage 1 HCC. METHODS: The National Cancer Database was queried to identify patients that underwent resection for HCC. RESULTS: In this study, 2990 patients with a single tumor, and 1087 patients with multifocal disease confined to one lobe underwent resection. In the multifocal cohort, patients with clinical stage 3 (HR 1.54, CI 1.31-1.81, p < 0.0001) or 4 (HR 2.27, CI 1.57-3.29, p < 0.0001) disease, and those with moderately-differentiated (HR 1.32, CI 1.06-1.64, p = 0.012) or poorly differentiated/undifferentiated tumors (HR 1.53, CI 1.20-1.95, p = 0.0006) were associated with worse overall survival (OS). There was no difference in OS between patients with well-differentiated clinical stage 2 multifocal HCC and those with all grades of clinical stage 1 HCC (median of 84.8 (CI 66.3-107.2) vs 76.2 months (CI 71.2-81.3), respectively, p = 0.356). CONCLUSIONS: Patients with well-differentiated, clinical stage 2 multifocal HCC confined to one lobe experience similar OS following hepatic resection to patients with clinical stage 1 disease. These findings may impact the management of select patients with multifocal HCC.

Resection and chemotherapy is the optimal treatment approach for patients with clinically node positive intrahepatic cholangiocarcinoma.

BACKGROUND: Clinically lymph node positive (cLNP) intrahepatic cholangiocarcinoma (ICC) carries a poor prognosis, without clear management guidelines for the practicing clinician. We sought to evaluate current practice patterns for cLNP ICC, including associations with survival. METHODS: The National Cancer Database was queried for patients with cLNP ICC, without extrahepatic metastases. RESULTS: We identified 1023 patients with cLNP ICC, 77%% (n = 784) of whom received chemotherapy alone. Resection was undertaken in 23% (n = 239) of patients and was most commonly utilized in combination with chemotherapy (n = 150). Median survival for all patients was 13.6 months. Patients undergoing resection in combination with chemotherapy were associated with an improved survival (22.5 months) as compared to those patients receiving chemotherapy alone (11.9 months) or resection alone (12.4 months) (p < 0.01). Finally, we compared the survival of patients with cLNP ICC with that of patients with pathologically proved lymph node positive (pLNP) ICC, all of whom were treated with resection with chemotherapy, and found no difference in survival (22.5 months-19.3 months, p = 0.99, respectively). CONCLUSIONS: While the decision to pursue resection for ICC is multifactorial and patient specific, the presence of clinically positive LNs should not represent a contraindication.

Disease-free interval and tumor functional status can be used to select patients for resection/ablation of liver metastases from adrenocortical carcinoma: insights from a multi-institutional study.

BACKGROUND: Adrenocortical carcinoma (ACC) is an aggressive malignancy that frequently metastasizes to the liver. Given the limitations of systemic therapy in this setting, we sought to determine characteristics associated with a two-fold increase in survival with resection/ablation compared to that reported with chemotherapy alone (∼12 months). METHODS: Patients who underwent resection/ablation at our institutions for ACC liver metastases were identified. Those who survived 12-24 months after metastasectomy were excluded, as the aim was to characterize patients who most clearly benefited from these procedures. Clinicopathologic and treatment characteristics were assessed for associations with survival. RESULTS: Sixty-two patients met inclusion criteria, of whom 44 survived >24 months and 18 survived <12 months. Patients with extended survival were less likely to have functioning tumors (p = 0.047), had fewer liver metastases (p = 0.047), and a longer disease-free interval (DFI) (median 17.6 vs 2.3 months, p < 0.0001). On multivariable analysis, DFI (OR = 1.33, 95% CI = 1.12-1.58) and non-functioning tumor (OR = 0.13, 95% CI = 0.13-0.56) were independently associated with prolonged survival. CONCLUSION: Metastasectomy/ablation should be considered for patients with ACC liver metastases. DFI and tumor functional status may be useful in selecting optimal candidates for these procedures.

A Survey of the Complex General Surgical Oncology Fellowship Programs Regarding Applicant Selection and Rank.

BACKGROUND: There is significant demand for training in Complex General Surgical Oncology (CGSO) fellowships. Previous work has explored objective quantitative metrics of applicants that matriculated to CGSO fellowships; however, ambiguity remains concerning academic benchmarks and qualitative factors that impact matriculation. STUDY DESIGN: A web-based survey was sent to each ACGME/SSO-approved CGSO fellowship training program. The survey was comprised of 24 questions in various forms, including dichotomous, ranked, and five-point Likert scale questions. RESULTS: Twenty-nine of 30 program directors (97%) submitted complete survey responses, representing 64 of the 65 CGSO fellowship positions (99%) currently offered. Programs received a mean of 73 applications per cycle (range 50-125) and granted a mean of 26 interviews (range 2-45). Seventy-two percent of programs had an established benchmark for ABSITE score percentile before offering a candidate an interview, with 62% of those programs setting that benchmark above the 50th percentile. The majority of programs also had established benchmarks for quantity of first author publications (mean: 2.3) and all publications of any authorship (mean: 4.4). An applicant's interview was ranked as the most important factor in determining inclusion on the program's rank list. The ability to work as part of a team, interpersonal interaction/communication abilities, and operative skills were rated as most important applicant characteristics, whereas an applicant's personal statement was ranked as least important. CONCLUSIONS: After established academic benchmarks have been met, a multitude of factors influences ranking of applicants to the CGSO fellowship, most of which are assessed at the interview.
