Prophylactic Cholecystectomy is Safe in Patients Undergoing Cytoreductive Surgery With Hyperthermic Intraperitoneal Chemotherapy.

BACKGROUND: While cholecystectomy is one of the most common operations performed in the United States, there is a continued debate regarding its prophylactic role in elective surgery. Particularly among patients with peritoneal carcinomatosis who undergo cytoreduction surgery with hyperthermic intraperitoneal chemotherapy (CRS-HIPEC), further abdominal operations may pose increasing morbidity due to intraabdominal adhesions and potential recurrence. This bi-institutional retrospective study aims to assess postoperative morbidity associated with prophylactic cholecystectomy at the time of CRS-HIPEC. METHODS: We performed a bi-institutional retrospective analysis of 578 patients who underwent CRS-HIPEC from 2011 to 2021. Postoperative outcomes among patients who underwent prophylactic cholecystectomy at the time of CRS-HIPEC were compared to patients who did not, particularly rate of bile leak, hospital length of stay, rate of Clavien-Dindo classification morbidity grade III or greater, and number of hospital re-admissions within 30 days. RESULTS: Of the 535 patients available for analysis, 206 patients (38.3%) underwent a prophylactic cholecystectomy. Of the 3 bile leaks (1.5%) that occurred among patients who underwent prophylactic cholecystectomy, all 3 occurred in patients who underwent a concomitant liver resection. There were no significant differences in hospital length of stay, postoperative morbidity, and number of hospital re-admissions among patients who underwent prophylactic cholecystectomy compared to those who did not. CONCLUSION: Prophylactic cholecystectomy in patients undergoing CRS-HIPEC is not associated with increased morbidity or increased bile leak risk compared to historical data. While the benefits of prophylactic cholecystectomy are not yet elucidated, it may be considered to avoid potential future morbid operations for biliary disease.

Racial disparities of gastric cancer in the USA: an overview of epidemiology, global screening guidelines, and targeted screening in a heterogeneous population.

Gastric cancer is the fifth most common cancer diagnosis and fourth leading cause of cancer-related death globally. The incidence of gastric cancer in the USA shows significant racial and ethnic disparities with gastric cancer incidence in Korean Americans being over five times higher than in non-Hispanic whites. Since gastric cancer is not common in the USA, there are no current screening guidelines. In countries with higher incidences of gastric cancer, screening guidelines have been implemented for early detection and intervention and this has been associated with a reduction in mortality. Immigrants from high incidence countries develop gastric cancer at lower rates once outside of their country of origin, but continue to be at higher risk for developing gastric cancer. This risk does seem to decrease with subsequent generations. With increasing availability of endoscopy, initiating gastric cancer screening guidelines for high-risk groups can have the potential to improve survival by diagnosing and treating gastric cancer at an earlier stage. This article aims to provide context to gastric cancer epidemiology globally, review risk factors for developing gastric cancer, highlight racial and ethnic disparities in gastric cancer burden in the USA, examine current guidelines that exist in high incidence countries, and suggest future studies examining the efficacy of additional screening in high-risk populations to reduce gastric cancer mortality and disparate burden on ethnic minorities in the USA.

Factors Impacting Academic Productivity and Satisfaction of Surgeon-scientists: A Nationwide Survey.

OBJECTIVE: To identify factors related to research success for academic surgeons. SUMMARY BACKGROUND DATA: Many recognize mounting barriers to scientific success for academic surgeons, but little is known about factors that predict success for individual surgeons. METHODS: A phase 1 survey was emailed to department chairpersons at highly funded US departments of surgery. Participating chairpersons distributed a phase 2 survey to their faculty surgeons. Training- and faculty-stage exposures and demographic data were collected and compared with participant-reported measures of research productivity. Five primary measures of productivity were assessed including number of grants applied for, grants funded, papers published, first/senior author papers published, and satisfaction in research. RESULTS: Twenty chairpersons and 464 faculty surgeons completed the survey, and 444 faculty responses were included in the final analysis. Having a research-focused degree was significantly associated with more grants applied for (PhD, incidence rate ratio (IRR)=6.93; masters, IRR=4.34) and funded (PhD, IRR=4.74; masters, IRR=4.01) compared to surgeons with only clinical degrees (all P<0.01). Having a formal research mentor was significantly associated with more grants applied for (IRR=1.57, P=0.03) and higher satisfaction in research (IRR=2.22, P<0.01). Contractually protected research time was significantly associated with more grants applied for (IRR=3.73), grants funded (IRR=2.14), papers published (IRR=2.12), first/senior authors published (IRR=1.72), and research satisfaction (Odds ratio=2.15) (all P<0.01). The primary surgeon-identified barrier to research productivity was lack of protection from clinical burden. CONCLUSIONS: Surgeons pursuing research-focused careers should consider the benefits of attaining a research-focused degree, negotiating for contractually protected research time, and obtaining formal research mentorship.

Preoperative Frailty and Malnutrition in Surgical Oncology Patients Predicts Higher Postoperative Adverse Events and Worse Survival: Results of a Blinded, Prospective Trial.

BACKGROUND: Frailty, a multidimensional state leading to reduced physiologic reserve, is associated with worse postoperative outcomes. Despite the availability of various frailty tools, surgeons often make subjective assessments of patients' ability to tolerate surgery. The Risk Analysis Index (RAI) is a validated preoperative frailty assessment tool that has not been studied in cancer patients with plans for curative-intent surgery. METHODS: In this prospective, surgeon-blinded study, patients who had abdominal malignancy with plans for resection underwent preoperative frailty assessment with the RAI and nutrition assessment by measurement of albumin, prealbumin, and C-reactive protein (CRP). Postoperative outcomes and survival were assessed. RESULTS: The study included 220 patients, 158 (72%) of whom were considered frail (RAI ≥21). Frail patients were more likely to be readmitted within 30 and 90 days, (16% vs. 3% [P = 0.006] and 16% vs. 5% [P = 0.025], respectively). Patients with abnormal CRP, prealbumin, and albumin experienced higher rates of unplanned intensive care unit admission (CRP [27% vs. 8%; P < 0.001], albumin [30% vs. 10%; P < 0.001], prealbumin [29% vs. 9%; P < 0.001]) and increased postoperative mortality at 90 and 180 days. Survival was similar for frail and non-frail patients. In the multivariate analysis, frailty remained an independent risk factor for readmission (hazard ratio, 5.58; 95% confidence interval, 1.39-22.15; P = 0.015). In the post hoc analysis using the pre-cancer RAI score, the postoperative outcomes did not differ between the frail and non-frail patients. CONCLUSION: In conjunction with preoperative markers of nutrition, the RAI may be used to identify patients who may benefit from additional preoperative risk stratification and increased postoperative follow-up evaluation.

Effects of Specialist Palliative Care for Patients Undergoing Major Abdominal Surgery for Cancer: A Randomized Clinical Trial.

Importance: Specialist palliative care benefits patients undergoing medical treatment of cancer; however, data are lacking on whether patients undergoing surgery for cancer similarly benefit from specialist palliative care. Objective: To determine the effect of a specialist palliative care intervention on patients undergoing surgery for cure or durable control of cancer. Design, Setting, and Participants: This was a single-center randomized clinical trial conducted from March 1, 2018, to October 28, 2021. Patients scheduled for specified intra-abdominal cancer operations were recruited from an academic urban referral center in the Southeastern US. Intervention: Preoperative consultation with palliative care specialists and postoperative inpatient and outpatient palliative care follow-up for 90 days. Main Outcomes and Measures: The prespecified primary end point was physical and functional quality of life (QoL) at postoperative day (POD) 90, measured by the Functional Assessment of Cancer Therapy-General (FACT-G) Trial Outcome Index (TOI), which is scored on a range of 0 to 56 with higher scores representing higher physical and functional QoL. Prespecified secondary end points included overall QoL at POD 90 measured by FACT-G, days alive at home until POD 90, and 1-year overall survival. Multivariable proportional odds logistic regression and Cox proportional hazards regression models were used to test the hypothesis that the intervention improved each of these end points relative to usual care in an intention-to-treat analysis. Results: A total of 235 eligible patients (median [IQR] age, 65.0 [56.8-71.1] years; 141 male [60.0%]) were randomly assigned to the intervention or usual care group in a 1:1 ratio. Specialist palliative care was received by 114 patients (97%) in the intervention group and 1 patient (1%) in the usual care group. Adjusted median scores on the FACT-G TOI measure of physical and functional QoL did not differ between groups (intervention score, 46.77; 95% CI, 44.18-49.04; usual care score, 46.23; 95% CI, 43.08-48.14; P = .46). Intervention vs usual care group odds ratio (OR) was 1.17 (95% CI, 0.77-1.80). Palliative care did not improve overall QoL measured by the FACT-G score (intervention vs usual care OR, 1.09; 95% CI, 0.75-1.58), days alive at home (OR, 0.87; 95% CI, 0.69-1.11), or 1-year overall survival (hazard ratio, 0.97; 95% CI, 0.50-1.88). Conclusions and Relevance: This randomized clinical trial showed no evidence that early specialist palliative care improves the QoL of patients undergoing nonpalliative cancer operations. Trial Registration: ClinicalTrials.gov Identifier: NCT03436290.

Synovial sarcoma with intra-abdominal metastasis causing hemoperitoneum: a case-report.

Synovial sarcoma is a rare soft tissue sarcoma which frequently involves the upper or lower extremities. Soft tissue sarcomas including synovial sarcoma have a propensity to metastasize to the lungs, and there are very few reports of metastatic lesions in other locations.Here, we report a case of a 49-year-old patient who underwent neoadjuvant chemoradiation for an upper extremity synovial sarcoma and presented approximately 4 years later with abdominal pain and hemoperitoneum and was ultimately found to have metastatic synovial sarcoma involving the greater curvature of the stomach and surrounding peri-gastric soft tissue. We describe the multidisciplinary management of this complex patient presentation and propose that expanded surveillance imaging beyond that of the local tumor resection bed and the chest may be beneficial especially in tumors with high-risk features.

Association of Systemic Chemotherapy Approaches With Outcomes in Appendiceal Peritoneal Metastases.

INTRODUCTION: Many patients undergoing cytoreductive surgery with hyperthermic intraperitoneal chemotherapy (CRS-HIPEC) for appendiceal adenocarcinoma peritoneal metastases (APM) undergo preoperative systemic chemotherapy. The primary aim of this study is to evaluate differences in oncologic outcomes among two popular chemotherapy approaches in patients with APM undergoing CRS-HIPEC. METHODS: We performed a multicenter retrospective review of patients who underwent CRS-HIPEC for APM due to high or intermediate grade disease between 2013 and 2019. Patients in the total neoadjuvant therapy group (TNT) received 12 cycles of preoperative chemotherapy. Patients in the "sandwich" chemotherapy group (SAND) received six cycles of preoperative chemotherapy with a maximum of six cycles of postoperative chemotherapy. The primary outcomes were overall survival (OS) and recurrence-free survival (RFS) defined as months from date of first treatment or surgery, respectively. RESULTS: A total of 39 patients were included in this analysis, with 25 (64%) patients in the TNT group and 14 (36%) patients in the SAND group. Patients in the TNT group had a median OS of 62 mo, while median OS in the SAND group was 45 mo (P = 0.01). In addition, patients in the TNT group had significantly longer RFS compared to the SAND group (35 versus 12 mo, P = 0.03). In a multivariable analysis, TNT approach was independently associated with improved OS and RFS. CONCLUSIONS: In this multicenter retrospective analysis, a TNT approach was associated with improved overall and recurrence-free survival compared to a sandwiched chemotherapy approach in patients undergoing CRS-HIPEC for high or intermediate grade APM.

A total neoadjuvant chemotherapy approach is associated with improved recurrence-free survival in patients with colorectal peritoneal metastases undergoing cytoreductive surgery and HIPEC.

BACKGROUND: The primary aim of this study is to evaluate the oncologic outcomes of two popular systemic chemotherapy approaches in patients with colorectal peritoneal metastases (CPM) undergoing cytoreductive surgery with hyperthermic intraperitoneal chemotherapy (CRS-HIPEC). METHODS: We performed a dual-center retrospective review of consecutive patients who underwent CRS-HIPEC for CPM due to high or intermediate-grade colorectal cancer. Patients in the total neoadjuvant therapy (TNT) group received 6 months of preoperative chemotherapy. Patients in the "sandwich" (SAND) chemotherapy group received 3 months of preoperative chemotherapy with a maximum of 3 months of postoperative chemotherapy. RESULTS: A total of 34 (43%) patients were included in the TNT group and 45 (57%) patients in the SAND group. The median overall survival (OS) in the TNT and SAND groups were 77 and 61 months, respectively (p = 0.8). Patients in the TNT group had significantly longer recurrence-free survival (RFS) than the SAND group (29 vs. 12 months, p = 0.02). In a multivariable analysis, the TNT approach was independently associated with improved RFS. CONCLUSION: In this retrospective study, a TNT approach was associated with improved RFS, but not OS when compared with a SAND approach. Further prospective studies are needed to examine these systemic chemotherapeutic approaches in patients with CPM undergoing CRS-HIPEC.

Postoperative Respiratory Failure Following Cytoreductive Surgery and Hyperthermic Intraperitoneal Chemotherapy is Associated with Volume of Intraoperative Crystalloid Administration and Worse Survival.

BACKGROUND: Postoperative respiratory failure (PRF) is associated with increased morbidity after surgery. This retrospective study explores preoperative and perioperative risk factors associated with PRF in patients undergoing cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CRS/HIPEC) and the resultant impact on survival. METHODS: We identified all patients who underwent CRS/HIPEC at our institution between 2007 and 2017. PRF was defined as mechanical ventilation for more than 48 h after surgery or reintubation not related to an additional procedure within the first 30 days postoperatively. The relationship between clinicopathologic variables and PRF was examined using Kaplan-Meier log-rank survival analysis and multivariable Cox regression models with 90-day, 1-year and 5-year overall survival (OS). RESULTS: Overall, 314 patients underwent CRS/HIPEC, of whom 24 patients (7.6%) developed PRF. On univariable analysis, chronic obstructive pulmonary disease (COPD) was the only preoperative risk factor associated with PRF (p = 0.049). Of the intraoperative risk factors, diaphragmatic resection (p = 0.008), Peritoneal Cancer Index (PCI) > 20 (p < 0.001), and volume of intraoperative crystalloid (p < 0.001) were all associated with PRF. On multivariable Cox regression, only intraoperative crystalloid was significantly associated with PRF (p < 0.001), with a volume above 5.3 L (area under the curve [AUC] 0.77) having a high predictive accuracy for PRF. Five-year OS was significantly decreased in patients with PRF (30.2% vs. 52.6%, hazard ratio 2.6, 95% confidence interval 1.5-4.4; p < 0.001). CONCLUSIONS: Liberal intraoperative crystalloid volume resuscitation is a potential independent, modifiable intraoperative risk factor for PRF following CRS/HIPEC that may contribute to decreased long-term OS.

Safety and Clinical Value of Prophylactic Ureteral Stenting Before Cytoreductive Surgery With Hyperthermic Intraperitoneal Chemotherapy.

BACKGROUND: Prophylactic ureteral stents (PUS) are typically placed prior to complex abdominal or pelvic operations at the surgeon's discretion to help facilitate detection of iatrogenic ureteral injury. However, its usefulness and safety in the setting of cytoreductive surgery with hyperthermic intraperitoneal chemotherapy (CRS-HIPEC) have not been examined. This study aims to evaluate the potential clinical value and risk profile of prophylactic ureteral stent placement prior to CRS-HIPEC. METHODS: We performed a single-institutional retrospective analysis of 145 patients who underwent CRS-HIPEC from 2013 to 2021. Demographic and operative characteristics were compared between patients who underwent PUS placement and those that did not. Ureteral stent-related complications were evaluated. RESULTS: Of the 145 patients included in the analysis, 124 underwent PUS placement. There were no significant differences in patient demographics, medical comorbidities, or tumor characteristics. Additionally, PUS placement did not significantly increase operative time and was not associated with increased pelvic organ resection. However, patients who underwent prophylactic ureteral stenting had significantly higher peritoneal carcinomatosis index score (15.1 vs 9.1, P=.002) and increased rate of ureteral complications (24.2% vs 14.3%, P=.04), which led to lengthened hospital stay (13.2 days vs 8.1 days, P= .03). Notably, the sole ureteral injury and three cases of hydronephrosis were seen in patients who underwent PUS. CONCLUSION: Prophylactic ureteral stent placement in patients undergoing CRS-HIPEC may be useful, particularly in patients with predetermined extensive pelvic disease. However, PUS placement is not without potential morbidity and should be selectively considered in patients for whom benefits outweigh the risks.

Hypophosphatemia Is Associated With Postoperative Morbidity After Cytoreductive Surgery and Heated Intraperitoneal Chemotherapy: A Retrospective Study.

INTRODUCTION: Hypophosphatemia following surgery is associated with a higher rate of postoperative complications; however, the significance of postoperative hypophosphatemia after cytoreductive surgery and heated intraperitoneal chemotherapy (CRS/HIPEC) is unknown. METHODS: A prospectively maintained database was queried for all patients who underwent CRS/HIPEC for any histology at the Mount Sinai Health System. The perioperative serum phosphate levels, postoperative complications, and comorbidities were compared between patients with or without major complications. RESULTS: From 2007 to 2018, 327 patients underwent CRS/HIPEC. Most of the patients had low phosphate levels on postoperative day (POD) 2, reaching a median nadir of 2.3 mg/dL on POD 3. Patients with major complications had significantly lower levels of serum phosphate on POD 5-7 compared with patients without complications, with median serum phosphate 2.2 mg/dL (IQR 1.9-2.4) versus 2.7 mg/dL, (IQR 2.3-3), P < 0.01. Hypophosphatemia on POD 5-7 was also more frequent in patients who developed an anastomotic leak, with median serum phosphate 2.2 mg/dL (IQR 1.9-2.6) versus 2.8 mg/dL (IQR 2.2-3.2), P = 0.001. On multivariate analysis, the number of organs resected at surgery, diaphragm resection, postoperative intensive care unit stay, and serum phosphate level <2.4 mg/dL on POD 5-7 were independently associated with a major complication after CRS/HIPEC. CONCLUSIONS: Following CRS/HIPEC, POD 5-7 hypophosphatemia is associated with severe postoperative complications and anastomotic leak.

Gallbladder Cancer: A Single-Institution 10-Year Experience-Analysis of Adenocarcinoma Subtypes and Tumors Arising from Intracholecystic Papillary Neoplasms.

BACKGROUND: Gallbladder cancer accounts for 1.2% of global cancer diagnoses. Literature on biliary-type adenocarcinoma (BTA), and specifically carcinoma arising from intracholecystic papillary-tubular neoplasms (ICPNs), is limited. This study describes a retrospective, single-institution experience with gallbladder cancer, focusing on histological subtypes and prognosis. METHODS: A retrospective review was performed of patients who underwent cholecystectomy for a malignant neoplasm of the gallbladder between 2007 and 2017. Demographic, clinicopathologic, and operative variables, as well as survival outcomes, were analyzed. RESULTS: From a total of 145 patients, BTAs were most common (93, 64%). Compared with non-BTAs, BTAs were diagnosed at a lower American Joint Committee on Cancer stage (p = 0.045) and demonstrated longer median recurrence-free survival (38 vs. 16 months, p = 0.014; median follow-up 36 months). Tumors arising from ICPNs (18, 12%) were more commonly associated with BTA (14 cases). Compared with BTAs not associated with ICPNs (29 patients), associated cases demonstrated lower pathologic stage (p = 0.006) and lower rates of liver and perineural invasion (0% vs. 49% and 14% vs. 48%, respectively; p < 0.05). Cumulative 5-year survival probability was higher for patients with gallbladder neoplasm of any subtype associated with ICPNs compared with those that were not associated with ICPNs (54% vs. 41%, p = 0.019; median follow-up 23 months). This difference was also significant when comparing BTAs associated with ICPNs and non-associated cases (63% vs. 52%, p = 0.005). CONCLUSIONS: This study demonstrated unique pathological and prognostic features of BTAs and of carcinomas arising from ICPNs. Histopathological variance may implicate prognosis and may be used to better guide clinical decision making in the treatment of these patients.

Stapled Full-Thickness Diaphragm Resection: A Novel Approach to Diaphragmatic Resection in Cytoreductive Surgery with Hyperthermic Intraperitoneal Chemotherapy.

Full-thickness diaphragm resection (FT-DR) during cytoreductive surgery with hyperthermic intraperitoneal chemotherapy (CRS-HIPEC) is sometimes required to achieve a complete cytoreduction. It is conventionally performed with electrocautery with primary repair or mesh repair. FT-DR using a linear cutting stapler is a novel technique that avoids entry to the chest cavity and minimizes the use of electrocautery on the diaphragm. We performed an institutional retrospective review of a prospectively maintained database of 145 patients who underwent CRS-HIPEC between 2013 and 2019. Patients were divided into the Conventional or Stapled group based on the FT-DR approach indicated in the operative report. Of the 145 patients who underwent CRS-HIPEC, 27 underwent FT-DR, with 63% (n = 17) in the Stapled group. There were no significant demographic or oncologic differences between the 2 groups. Patients in the Stapled group underwent tube thoracostomy (13.3% vs 60%; p = 0.008), were diagnosed with pneumonia (12% vs 50%; p = 0.04), required reintubation (6% vs 40%; p = 0.03), and required mechanical ventilation more than 48 hours (6% vs 50%; p = 0.02) less frequently than the Conventional group. There was no difference in pleural recurrence between the 2 groups (Conventional 20% vs Stapled 12%, p = 0.56). Stapled full-thickness diaphragm resection is a novel approach to achieving a complete cytoreduction that excludes the pleural cavity, minimizes diaphragm manipulation, and is associated with improved postoperative pulmonary outcomes in patients undergoing CRS-HIPEC.

Laparoscopic cytoreductive surgery and hyperthermic intraperitoneal chemotherapy is associated with improved perioperative outcomes: a single-center early experience propensity-matched analysis.

INTRODUCTION: The role of laparoscopy in cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CRS/HIPEC) is not well established. Herein, we describe our early experience of laparoscopic CRS/HIPEC in patients with low-volume peritoneal disease compared to patients who underwent open CRS/HIPEC during the same time period. METHODS: Using a prospectively maintained database, patients who underwent laparoscopic CRS/HIPEC were compared to a control cohort of patients who underwent open CRS/HIPEC, matched for peritoneal carcinomatosis index (PCI), completeness of cytoreduction, and tumor histology. RESULTS: Between 2008 and 2017, 16 patients underwent laparoscopic CRS/HIPEC and were compared to a matched control cohort of 32 patients who underwent open CRS/HIPEC. Clinical and demographic data were similar between the groups. PCI, number of resected organs, and optimal cytoreduction rates were comparable. Patients who underwent laparoscopic experienced a lower estimated blood loss, (median, [IQR 1-3]); 150 mL, [50-300] vs. 100 mL, [50-125], p = 0.04, shorter length of stay (median [IQR 1-3]; 4 days [3-6] vs. 6 days [5-8], p < 0.01, and a lower 30-day complication rate (6.3% vs. 56.3%, p < 0.01). There was no difference in progression-free survival (p = 0.577) and overall survival (p = 0.472) between the groups. CONCLUSIONS: This preliminary study demonstrates that laparoscopic CRS/HIPEC is feasible and safe for curative treatment in selected patients with low tumor volume. Minimally invasive CRS/HIPEC is associated with fewer postoperative complications and shorter length of stay. There was no difference in long-term oncological outcomes between the groups.

Impact of Insurance Status on Oncologic and Perioperative Outcomes After Cytoreductive Surgery with Hyperthermic Intraperitoneal Chemotherapy.

BACKGROUND: A growing body of research has shown that underinsured patients are at increased risk of worse health outcomes compared with insured patients. Cytoreductive surgery with hyperthermic intraperitoneal chemotherapy (CRS-HIPEC) is largely performed at highly specialized cancer centers and may pose challenges for the underinsured. This study investigates surgical outcomes following CRS-HIPEC for insured and underinsured patients with peritoneal carcinomatosis. METHODS: We performed a retrospective cohort study of 125 patients undergoing CRS-HIPEC between 2013 and 2019. Patients were categorized into two groups. The insured group was comprised of patients with private insurance at the time of CRS-HIPEC or who obtained it during the follow-up period. The underinsured group consisted of patients with Medicaid, or self-pay. Perioperative and oncologic outcomes were compared between the two groups. RESULTS: A total of 102 (82.3%) patients were insured, and 22 (17.7%) patients were underinsured. There were no significant differences in age, medical morbidities, primary tumor characteristics, peritoneal carcinomatosis index, or completion of cytoreduction score between the two groups. The median overall survival (OS) for insured patients was 64.8 months and was 52.9 months for underinsured patients (p = 0.01). Additionally, insured patients had a significantly longer follow-up time. Underinsurance status also was associated with increased hospital and intensive care unit length of stay, and higher rate of Clavien-Dindo classification III-IV complications. CONCLUSIONS: In this retrospective study conducted at a large, urban, specialized cancer center, private insurance status was associated with increased overall survival and longer follow-up period. Furthermore, underinsurance status was associated with increased perioperative morbidity.

African Immigrants in New York City with Hepatitis B-Related Hepatocellular Carcinoma Demonstrate High Morbidity and Mortality.

Guidelines recommend hepatitis B (HBV) testing in individuals from endemic areas, and if positive, screening for hepatocellular carcinoma (HCC). While screening programs are well established in the Asian immigrant population in New York City (NYC), less is known about the characteristics of HBV/HCC among the African immigrant community. A retrospective review was performed of HCC cases from 2005 to 2018 at our institution. Country of origin was not documented in the electronic medical record; therefore, African immigrant status was approximated using self-identified race/ethnicity, positive HBV status, and an online registry to determine country of origin based on last name. Surnames with the greatest prevalence or density in an African country were considered. Among 4400 patients with HCC, 472 identified as non-Hispanic Black; of these, 86 were HBV+. Based on surname, it was estimated that 33 individuals were likely immigrants from Africa. In this group, median age of HCC diagnosis was 48 years (IQR 43-55). In patients with an available date of HBV diagnosis (n = 24), 17 (71%) were unaware of their HBV status when they presented with HCC. Zero patients were diagnosed with HCC through routine screening, most patients (66%) were diagnosed upon imaging evaluation of symptoms. Twelve patients (36%) underwent resection or transplantation; the remaining 64% were ineligible for surgical treatment. Of the 26 patients with follow-up data, 18 (69%) died of disease or were critically ill at last encounter, and of these, 14 (77%) died within 1 year of HCC diagnosis. In conclusion, African immigrants in NYC with HBV/HCC are at high risk of HCC related mortality at a young age. Most were unaware of their hepatitis status at the time of HCC diagnosis. No patients were enrolled in routine HCC screening; the majority were diagnosed based on imaging obtained for symptoms. Most individuals presented with inoperable disease, and the majority died within months of diagnosis. Awareness of these findings may help healthcare providers improve patient outcomes.

Diagnostic Laparoscopy in Patients With Peritoneal Carcinomatosis Is Safe and Does Not Delay Cytoreductive Surgery With Hyperthermic Intraperitoneal Chemotherapy.

BACKGROUND: Outcomes of cytoreductive surgery with hyperthermic intraperitoneal chemotherapy (CRS-HIPEC) among patients with peritoneal carcinomatosis (PC) depend largely on the extent of peritoneal disease. Since PC is not reliably evaluated with cross-sectional imaging, tumor burden is often evaluated with diagnostic laparoscopy (DLS). The aims of this study are to evaluate the safety of DLS in patients with peritoneal disease and determine if DLS delays time to CRS-HIPEC. METHODS: We performed an institutional retrospective review of 145 patients who underwent CRS-HIPEC between 2013 and 2020. Patients were divided into 2 groups: those who underwent an electively scheduled DLS prior to CRS-HIPEC and those who did not. Intraoperative and postoperative complications associated with DLS were determined from the surgeon's operative report. Time from diagnosis of PC to CRS-HIPEC was compared between the 2 groups. RESULTS: Of the 145 patients available for analysis, 47% (68) underwent DLS and 44% (64) did not. Of all the diagnostic laparoscopies performed, there was 1 (1.5%) intraoperative complication. The duration between diagnosis of peritoneal carcinomatosis and surgery was 4.9 months among patients who underwent DLS prior to CRS-HIPEC and 4.3 months among patients who did not (P = .79). CONCLUSION: In this retrospective analysis, diagnostic laparoscopy prior to CRS-HIPEC demonstrated a comparable rate of DLS-associated complications compared to other gastrointestinal malignancies and does not prolong time from diagnosis to CRS-HIPEC. Thus, in patients undergoing evaluation for CRS-HIPEC, diagnostic laparoscopy provides significant value in patient selection without incurring perioperative risk or delay in CRS-HIPEC.

Adjuvant Chemotherapy Is Not Guided by Pathologic Treatment Effect After Neoadjuvant Chemotherapy in Pancreatic Cancer.

OBJECTIVES: Currently, there is no guidance for optimal adjuvant chemotherapy selection after pancreatectomy with a partial or poor response to neoadjuvant therapy. This study seeks to describe an institution's practice patterns of adjuvant chemotherapy selection after neoadjuvant therapy. METHODS: Patients at a single institution receiving neoadjuvant chemotherapy followed by pancreatectomy for pancreatic cancer were reviewed. Patients enrolled in trials or without follow-up were excluded. Types of chemotherapy, the College of American Pathologists pathologic tumor response, and medical oncology plans were recorded. RESULTS: Forty-one patients met inclusion criteria. Pathologic review of treatment effect demonstrated that 3 patients (7.3%) had complete pathologic response, 3 (7.3%) had near complete pathologic response, 16 (39%) had partial response, and 14 (34.1%) had poor/no response to neoadjuvant chemotherapy. Fourteen of the 30 patients with partial or poor response (46.7%) received an alternate adjuvant regimen. Pathologic response to neoadjuvant chemotherapy specifically guided therapy in 11 (30.5%) patients. CONCLUSIONS: Despite 73.1% of patients with partial or poor response to neoadjuvant chemotherapy, only 46.7% received a different adjuvant regimen. Medical oncologists infrequently considered treatment effect when choosing adjuvant therapy. Pathologic response to neoadjuvant chemotherapy should be considered when selecting adjuvant chemotherapy.
