- Abstract
Importance: Despite the clear potential benefits of neoadjuvant therapy, the optimal neoadjuvant regimen for patients with high-risk resectable melanoma (HRRM) is not known., Objective: To compare the safety and efficacy of dual checkpoint inhibitors with anti-programmed cell death protein-1 (anti-PD1) therapy in a neoadjuvant setting among patients with HRRM., Design, Setting, and Participants: In this pooled analysis of clinical trials, studies were selected provided they investigated immune checkpoint inhibitor treatment, were published between January 2018 and March 2023, and were phase 1, 2, or 3 clinical trials. Participant data included in the analysis were derived from trials evaluating the efficacy and safety of anti-PD1 monotherapy and the combination of anti-cytotoxic T lymphocyte-associated protein-4 with anti-PD1 in the neoadjuvant setting, specifically among patients with HRRM., Interventions: Patients were treated with either anti-PD1 monotherapy; dual checkpoint inhibition (DCPI) with a conventional dose of 3-mg/kg ipilimumab and 1-mg/kg nivolumab; or DCPI with an alternative-dose regimen of 1-mg/kg ipilimumab and 3-mg/kg nivolumab., Main Outcomes and Measures: The main outcomes were radiologic complete response (rCR), radiologic overall objective response (rOOR), and radiologic progressive disease. Also, pathologic complete response (pCR), the proportion of patients undergoing surgical resection, and occurrence of grade 3 or 4 immune-related adverse events (irAEs) were considered., Results: Among 573 patients enrolled in 6 clinical trials, neoadjuvant therapy with DCPI was associated with higher odds of achieving pCR compared with anti-PD1 monotherapy (odds ratio [OR], 3.16; P < .001). DCPI was associated with higher odds of grade 3 or 4 irAEs compared with anti-PD1 monotherapy (OR, 3.75; P < .001). When comparing the alternative-dose ipilimumab and nivolumab (IPI-NIVO) regimen with conventional-dose IPI-NIVO, no statistically significant difference in rCR, rOOR, radiologic progressive disease, or pCR was noted. However, the conventional-dose IPI-NIVO regimen was associated with increased grade 3 or 4 irAEs (OR, 4.76; P < .001). Conventional-dose IPI-NIVO was associated with greater odds of achieving improved rOOR (OR, 1.95; P = .046) and pCR (OR, 2.99; P < .001) compared with anti-PD1 monotherapy. The alternative dose of IPI-NIVO also was associated with higher odds of achieving rCR (OR, 2.55; P = .03) and pCR (OR, 3.87; P < .001) compared with anti-PD1 monotherapy. The risk for grade 3 or 4 irAEs is higher with both the conventional-dose (OR, 9.59; P < .001) and alternative-dose IPI-NIVO regimens (OR, 2.02; P = .02) compared with anti-PD1 monotherapy., Conclusion and Relevance: In this pooled analysis of 6 clinical trials, although DCPI was associated with increased likelihood of achieving pathological and radiologic responses, the associated risk for grade 3 or 4 irAEs was significantly lower with anti-PD1 monotherapy in the neoadjuvant setting for HRRM. Additionally, compared with alternative-dose IPI-NIVO, the conventional dose of IPI-NIVO was associated with increased risk for grade 3 or 4 irAEs, with no significant distinctions in radiologic or pathologic efficacy.

- Abstract
Purpose of Review: Patient navigation promotes access to timely treatment of chronic diseases by eliminating barriers to care. Patient navigation programs have been well-established in improving screening rates and diagnostic resolution. This systematic review aimed to characterize the multifaceted role of patient navigators within the realm of cancer treatment., Recent Findings: A comprehensive electronic literature review of PubMed and Embase databases was conducted to identify relevant studies investigating the role of patient navigators in cancer treatment from August 1, 2009 to March 27, 2023. Fifty-nine articles were included in this review. Amongst studies focused on cancer treatment initiation, 70% found a significant improvement in treatment initiation amongst patients who were enrolled in patient navigation programs, 71% of studies focused on treatment adherence demonstrated significant improvements in treatment adherence, 87% of studies investigating patient satisfaction showed significant benefits, and 81% of studies reported a positive impact of patient navigators on quality care indicators. Three palliative care studies found beneficial effects of patient navigation. Thirty-seven studies investigated disadvantaged populations, with 76% of them concluded that patient navigators made a positive impact during treatment. This systematic review provides compelling evidence supporting the value of patient navigation programs in cancer treatment. The findings suggest that patient navigation plays a crucial role in improving access to care and optimizing treatment outcomes, especially for disadvantaged cancer patients. Incorporating patient navigation into standard oncology practice can reduce disparities and improve the overall quality of cancer care., (© 2024. The Author(s).)

- Abstract
Objective: To define neighborhood-level disparities in the receipt of complex cancer surgery., Background: Little is known about the geographic variation of receipt of surgery among patients with complex gastrointestinal (GI) cancers, especially at a small geographic scale., Methods: This study included individuals diagnosed with 5 invasive, nonmetastatic, complex GI cancers (esophagus, stomach, pancreas, bile ducts, liver) from the Ohio Cancer Incidence Surveillance System during 2009 and 2018. To preserve patient privacy, we combined US census tracts into the smallest geographic areas that included a minimum number of surgery cases (n=11) using the Max-p-regions method and called these new areas "MaxTracts." Age-adjusted surgery rates were calculated for MaxTracts, and the Hot Spot analysis identified clusters of high and low surgery rates. US Census and CDC PLACES were used to compare neighborhood characteristics between the high- and low-surgery clusters., Results: This study included 33,091 individuals with complex GI cancers located in 1006 MaxTracts throughout Ohio. The proportion in each MaxTract receiving surgery ranged from 20.7% to 92.3% with a median (interquartile range) of 48.9% (42.4-56.3). Low-surgery clusters were mostly in urban cores and the Appalachian region, whereas high-surgery clusters were mostly in suburbs. Low-surgery clusters differed from high-surgery clusters in several ways, including higher rates of poverty (23% vs. 12%), fewer married households (40% vs. 50%), and more tobacco use (25% vs. 19%; all P <0.01)., Conclusions: This improved understanding of neighborhood-level variation in receipt of potentially curative surgery will guide future outreach and community-based interventions to reduce treatment disparities. Similar methods can be used to target other treatment phases and other cancers., Competing Interests: The authors report no conflicts of interest., (Copyright © 2023 Wolters Kluwer Health, Inc.

- Abstract
Background: The National Comprehensive Cancer Network (NCCN) guidelines recommend adjuvant chemotherapy (AC) within 6-8 weeks of surgical resection for patients with stage III colon cancer. However, postoperative complications or prolonged surgical recovery may affect the receipt of AC. The aim of this study was to assess the utility of AC for patients with prolonged postoperative recovery., Methods: We queried the National Cancer Database (2010-2018) for patients with resected stage III colon cancer. Patients were categorized as having either normal or prolonged length of stay (PLOS: >7 days, 75th percentile). Multivariable Cox proportional hazard regression and logistic regressions were used to identify factors associated with overall survival and receipt of AC., Results: Of the 113,387 patients included, 30,196 (26.6%) experienced PLOS. Of the 88,115 (77.7%) patients who received AC, 22,707 (25.8%) initiated AC more than 8 weeks after surgery. Patients with PLOS were less likely to receive AC (71.5% vs. 80.0%, OR: 0.72, 95%CI=0.70-0.75) and displayed inferior survival (75 vs. 116 months, HR: 1.39, 95%CI=1.36-1.43). Receipt of AC was also associated with patient factors such as high socioeconomic status, private insurance, and White race (p<0.05 for all). AC within and after 8 weeks of surgery was associated with improved survival for patients with both normal LOS and PLOS (normal LOS: <8 weeks HR: 0.56, 95% CI: 0.54-0.59, >8 weeks HR: 0.68, 95% CI: 0.65-0.71; PLOS: <8 weeks HR: 0.51, 95% CI: 0.48-0.54, >8 weeks HR: 0.63, 95% CI 0.60-0.67). AC was associated with significantly improved survival if initiated up to 15 weeks postoperatively (normal LOS: HR: 0.72, 95%CI=0.61-0.85; PLOS: HR: 0.75, 95%CI=0.62-0.90), and very few patients (<3.0%) initiated AC beyond this time., Conclusion: Receipt of AC for stage III colon cancer may be affected by surgical complications or otherwise prolonged recovery. Timely and even delayed AC (>8 weeks) are both associated with improved overall survival. These findings highlight the importance of delivering guideline-based systemic therapies, even after complicated surgical recovery., (© 2023. The Society for Surgery of the Alimentary Tract.)

- Abstract
Background and Objectives: The Risk Analysis Index (RAI) accurately predicts adverse postoperative outcomes but the inclusion of cancer status in the RAI has raised two key concerns about its suitability for use in surgical oncology: (1) the potential over classification of cancer patients as frail, and (2) the potential overestimation of postoperative mortality for patients with surgically curable cancers., Methods: We performed a retrospective cohort analysis to assess the RAI's power to appropriately identify frailty and predict postoperative mortality in cancer patients. We assessed discrimination for mortality and calibration across five RAI models-the complete RAI and four variants that removed different cancer-related variables., Results: We found that the presence of disseminated cancer was a key variable driving the RAI's power to predict postoperative mortality. The model including only this variable [RAI (disseminated cancer)] was similar to the complete RAI in the overall sample (c = 0.842 vs. 0.840) and outperformed the complete RAI in the cancer subgroup (c = 0.736 vs 0.704, respectively, p < 0.0001, Max R
2 = 19.3% vs. 15.1%, respectively)., Conclusion: The RAI demonstrates somewhat less discrimination when applied exclusively to cancer patients, but remains a strong predictor of postoperative mortality, especially in the setting of disseminated cancer., (© 2023 Wiley Periodicals LLC.

- Abstract
A 9-month-old girl born with an interrupted aortic arch type B, an arteria lusoria (aberrant right subclavian artery) and a multilevel left ventricular outflow tract obstruction underwent a Yasui completion after an initial interim palliation. After the Damus-Kaye-Stansel procedure was carried out and the Sano shunt had been established as a source of pulmonary flow, the reported procedure comprised closure of the ventricular septal defect and the intraventricular baffling of left ventricular outflow through a malaligned ventricular septal defect, incision and partial resection of a conal septum and establishment of a right ventricle-to-pulmonary artery connection using an autologous left atrial appendage as a free graft. This technique consisted of dissecting and harvesting the left atrial appendage, which was then used as autologous material for an interposition plasty connecting the central pulmonary artery bifurcation segment with the upper rim of the infundibulotomy. Native, autologous tissue thus comprised the backwall of the newly created right ventricle-to-pulmonary artery continuity. Porcine pericardial patch plasty was then used to complete the remaining circumference of the right ventricle-to-pulmonary artery continuity., (© The Author 2023.

- Abstract
Background: We examined the association between Medicaid expansion (ME) and the diagnosis, treatment, and survival of patients with hepatocellular carcinoma (HCC)., Methods: We identified patients with HCC <65yrs with Medicaid or without insurance within the National Cancer Database before (2010-2013) or after (2015-2017) ME with early (cT1) or intermediate/advanced (cT2-T4 or M1) disease., Results: We identified 4848 patients with HCC before and 4526 after ME. Prior to ME, there was no association between future ME status and diagnosis of early HCC (34.5% vs. 32.9%). There was no association between future ME status and treating early HCC with ablation, resection, or transplantation. Patients with early HCC in future ME states were less likely to die (HR = 0.81, 95% CI: 0.67-0.98). After ME, patients in ME states were more likely to be diagnosed with early HCC (39.2% vs. 32.1%). Patients with early disease in ME states were more likely to undergo resection (OR=1.78, 95% CI: 1.16-2.75) or transplantation (OR=3.20, 95% CI: 1.40-7.33). There was a further associated decrease in the hazard of death (HR=0.68, 95% CI: 0.54-0.86)., Conclusion: ME was associated with early diagnosis of HCC. For early HCC, ME was associated with increased utilization of resection and transplantation and improvement in survival., Competing Interests: Disclosures None., (Copyright © 2022 International Hepato-Pancreato-Biliary Association Inc.

- Abstract
Background: Hepatocellular carcinoma (HCC) is a leading cause of cancer mortality worldwide. Liver resections and transplantations have increasingly become feasible options for potential cure. These complex surgeries are inherently associated with increased rates of readmission. In the meanwhile, hospital readmission rates are rapidly becoming an important quality of care metric. Therefore, it is very important to understand the effect of 30-day readmission on mortality and the factors associated with increased 30- and 90-day mortality rates., Methods: This is a retrospective cohort study utilizing data from the National Cancer Database. Patients included were 18 years or older who underwent liver resection or liver transplantation for HCC between 2003 and 2011. Our primary outcomes of interest were 30- and 90-day mortality rates. Our primary independent variable of interest was 30-day readmission., Results: 16 658 patients underwent either a liver resection or transplantation for HCC between 2003 and 2011. For patients with liver transplantations, increased readmission rates were associated with lower risks of 30-day mortality ( P = .012) but a trend toward higher 90-day mortality ( P = .057). Patients who underwent liver resection for HCC also demonstrated increased readmission rates to be associated with lower risk of 30-day mortality ( P = .014) but higher 90-day mortality ( P ≤ .001)., Conclusion: This is the only study to utilize a national database to investigate the association between readmission rates and mortality rates of both liver transplantations and resections for patients with HCC. We demonstrate 30-day readmission to show no increase in 30-day mortality, but rather higher 90-day mortality.

- Abstract
Background: Pediatric heart transplant (HTx) recipients with congenital heart defects require complex concomitant surgical procedures with the risk of prolonging the allograft's ischemic time. Ex vivo allograft perfusion with the Organ Care System (OCS; Transmedics, Andover, MA) may improve survival of these challenging patients., Methods: In this retrospective, single-center study a consecutive series of 8 children with allografts preserved using the OCS was compared with 13 children after HTx with cold storage of the donor heart from March 2018 to March 2020., Results: Median recipient age in the control group was 18 months (range, 1-189) versus 155 months (range, 83-214) in the OCS group, and the baseline differences between the 2 groups were not significant. Fifty percent of the children in the OCS group had complex congenital heart defects (vs 15% of the control subjects). Median operation time during HTx in the OCS group was 616 minutes (range, 270-809) versus 329 minutes (range, 283-617). Because of the time of ex vivo allograft perfusion (265 minutes [range, 202-372]) median total ischemia time was significantly shorter in the OCS group: 78 minutes (range, 52-111) versus 222 minutes (range, 74-326). The incidence of primary graft, renal, or hepatic failure did not differ between the groups. Graft function and the occurrence of any treated rejection at follow-up revealed no significant difference between the 2 groups. One-year survival was 88% in the OCS group (vs 85%)., Conclusions: Ex vivo allograft perfusion enabled complex pediatric HTx, yielding outcomes as positive as those of children whose donor hearts were stored in ice-cold solution., (Copyright © 2021 The Society of Thoracic Surgeons.
