FA03.05: NEOADJUVANT CHEMOTHERAPY OR CHEMORADIOTHERAPY FOR ADENOCARCINOMA OF THE ESOPHAGUS

Abstract Background Multimodality treatment of patients with esophageal adenocarcinoma (EAC) improve survival, but the optimal treatment strategy remains undetermined. The aim of this study was to compare outcomes in patients undergoing neoadjuvant chemotherapy (nCT) and neoadjuvant chemoradiotherapy (nCRT) for EAC. Methods Patients who underwent nCT or nCRT followed by surgery for EAC were identified from a prospective database (2000–2017) and included in this study. After propensity score matching, we compared the impact of the treatments on postoperative complications, in-hospital mortality, pathological outcomes and survival rates. Results Of the 396 eligible patients, 262 patients were analysed following propensity score matching. This resulted in 131 patients in the nCT group versus 131 patients in the nCRT group. There were no significant differences between the nCT and nCRT groups for overall complications (59% vs 57%, P = 0.802) or in-hospital mortality (2% vs 0%, P = 0.156). Patients who had nCRT had more R0 resections (93% vs. 83%, P = 0.013), and a higher pathological complete response rate (15% vs. 5%, P < 0.001). The pattern of recurrence was similar (P = 0.753) and there were no differences in 5-year disease-free survival rates (nCT vs nCRT; 39% vs 39%, P = 0.879) or 5-year overall survival rates (nCT vs nCRT; 44% vs 33%, P = 0.645). Conclusion In this study no differences between nCT and nCRT were seen in postoperative complications and in-hospital mortality in patients treated for EAC. Inspite of improved complete resection and pathological response there was no difference in the overall survival between the treatment modalities.

Abstract Objective There are limited data from retrospective studies on whether therapeutic outcomes after regular pancreatectomy are superior to those after enucleation in patients with small, peripheral and well-differentiated non-functional pancreatic neuroendocrine tumors. This study aimed to compare the short- and long-term outcomes of regular pancreatectomy and enucleation in patients with non-functional pancreatic neuroendocrine tumors. Methods Between January 2007 and July 2020, 227 patients with non-functional pancreatic neuroendocrine tumors who underwent either enucleation (n = 89) or regular pancreatectomy (n = 138) were included. Perioperative complications, disease-free survival, and overall survival probabilities were compared. Propensity score matching was performed to balance the baseline differences between the two groups. Results The median follow-up period was 60.76 months in the enucleation group and 43.29 months in the regular pancreatectomy group. In total, 34 paired patients were identified after propensity score matching. The average operative duration in the enucleation group was significantly shorter than that in the regular pancreatectomy group (147.94 ± 42.39 min versus 217.94 ± 74.60 min, P < 0.001), and the estimated blood loss was also significantly lesser (P < 0.001). The matched patients who underwent enucleation displayed a similar overall incidence of postoperative complications (P = 0.765), and a comparable length of hospital stay (11.12 ± 3.90 days versus 9.94 ± 2.62 days, P = 0.084) compared with those who underwent regular pancreatectomy. There were no statistically significant differences between the two groups in disease-free survival and overall survival after propensity score matching. Conclusion Enucleation in patients with non-functional pancreatic neuroendocrine tumors was associated with shorter operative time, lesser intraoperative bleeding, similar overall morbidity of postoperative complications, and comparable 5-year disease-free survival and overall survival when compared with regular pancreatectomy.

Abstract Neoadjuvant treatments provided survival benefits over surgery alone in resectable locally advanced esophageal and esophagogastric junction (EGJ) cancer patients. Both neoadjuvant chemoradiotherapy (nCRT) and neoadjuvant chemotherapy (nCT) are shown to be effective treatments. However, the direct comparison between two methods based on histologic subtypes, squamous cell carcinoma (SCC) and adenocarcinoma (AC) is still limited. This study examined the hypothesis that nCRT could provide the better overall survival (OS) than nCT. Methods A comprehensive search of studies comparing nCRT and nCT in patients with esophageal and EGJ cancer based on histologic subtypes was conducted. A meta-analysis of randomized (8 articles) and non-randomized (15 articles) studies was performed using odds ratio (OR) and 95% confidence intervals (CI95%). The OS was the main objective, whereas the secondary objective were complete pathological response (pCR) rate, curative resection (R0) rate, locoregional progression free-survival (L-PFS) rate, postoperative complications and mortality. Results Twenty three articles included 1,671 SCC and 9,285 AC patients. Neither 3- nor 5-year OS was found to be different. However, SCC patients receiving nCRT showed the better 3-year OS (OR 1.67, CI95% 1.17–2.40, p = 0.005). Both pCR and R0 rates were superior in nCRT group (OR 3.30, CI95% 2.46–4.44 and 2.46, CI95% 1.66–3.65, p < 0.00001, respectively). The better 3-year L-PFS was observed in nCRT group (OR 1.47, CI95% 1.17–1.85, p = 0.008), but 5-year L-PFS was comparable. The 30-day mortality was comparable, while 90-day mortality was higher in nCRT group (OR 1.32, CI95% 1.01–1.72, p = 0.04). Conclusion The nCRT provided the better overall survival especially in SCC patients and also increased locoregional control. Meanwhile, postoperative complications and mortality were higher after nCRT. Due to clinical heterogeneity, the multidisciplinary team management for each patient is required before treatment.

Abstract Background: The benefits of surgical resection (SR) for various Barcelona Clinic Liver Cancer (BCLC) stages of hepatocellular carcinoma (HCC) remain unclear. We investigated the risk factors of overall survival (OS) and survival benefits of SR over nonsurgical treatments in patients with HCC of various BCLC stages.Methods: Overall, 2316 HCC patients were included, and their clinicopathological data and OS were recorded. OS was analyzed by the Kaplan-Meier method and Cox regression analysis. Propensity score matching (PSM) analysis was performed.Results: In total, 66 (2.8%), 865 (37.4%), 575 (24.8%) and 870 (35.0%) patients had BCLC stage 0, A, B, and C disease, respectively. Furthermore, 1302 (56.2%) of all patients, and 37 (56.9%), 472 (54.6%), 313 (54.4%) and 480 (59.3%) of patients with BCLC stage 0, A, B, and C disease, respectively, died. The median follow-up duration time was 20 (range 0-96) months for the total cohort and was subdivided into 52 (8-96), 32 (1-96), 19 (0-84), and 12 (0-79) months for BCLC stages 0, A, B, and C cohorts, respectively. The risk factors for OS were 1) SR and cirrhosis; 2) SR, cirrhosis, and Child-Pugh (C-P) class; 3) SR, hepatitis B virus (HBV) infection, and C-P class; and 4) SR, HBV infection, and C-P class for the BCLC stage 0, A, B, and C cohorts, respectively. Compared to non-SR treatment, SR resulted in significantly higher survival rates in all cohorts. The 5-year OS rates for SR vs non-SR were 44.0% vs 28.7%, 72.2% vs 42.6%, 42.6% vs 36.2, 44.6% vs 23.5%, and 41.4% vs 15.3% (all p-values<0.05) in the total and BCLC stage 0, A, B, and C cohorts, respectively. After PSM, SR resulted in significantly higher survival rates compared to non-SR treatment in various BCLC stages.Conclusion: SR conferred significant survival benefits to patients with HCC of various BCLC stages and should be considered a recommended treatment for select HCC patients, especially patients with BCLC stage B and C disease.

e16716 Background: Gallbladder cancer (GBC) is an uncommon but highly fatal malignancy. Surgery remains the only potentially curative treatment for GBC. The role of neoadjuvant chemotherapy in patients with locally advanced GBC undergoing surgery is unknown. We studied the association of neoadjuvant chemotherapy on survival in locally advanced GBC patients who underwent resection. Methods: We identified adult patients with locally advanced (stage III-IV) GBC who underwent definitive surgery between 2004 and 2016 using the National Cancer Database. Treatment was categorized as neoadjuvant chemotherapy plus surgery (NAT), surgery plus adjuvant therapy (AT), and surgery alone (SA). Categorical variables were compared using the chi-square test with Bonferroni correction. Kaplan-Meier and Cox regression were used for survival analyses. We used 1:3 nearest neighbor propensity score matching based on NAT for each group. Results: Out of a total of 5,962 patients, 122 (2.2%) received NAT, 2934 (53.6%) AT, and 2421 (44.2%) SA. NAT was associated with private insurance and treatment at an academic/research facility (all p < .001) while SA patients were older, Hispanic, had government insurance, and higher comorbidities (all p < .001). Although all groups had similar lymph node assessment (NAT: 45%, AT: 46%, SA: 37%, p < .001), NAT was associated with lymph node negative disease (NAT 23%, AT 13.2%, SA 13.2%, p < .001). Median overall survival was higher in NAT compared to AT or SA (21 vs. 14 vs. 6 months, p < .001) which persisted after propensity score matching (21 vs. 15 vs. 9 months, p < .001) and multivariable regression analysis (Table). In node positive GBC, NAT was associated with improved median overall survival (NAT 24, AT 18, SA 8 months, p < .001). Conclusions: NAT is infrequently used in patients with locally advanced GBC. NAT is associated with improved median overall survival compared to AT and SA, and appears to be most beneficial in node positive disease. Prospective studies are needed to evaluate the role of neoadjuvant chemotherapy in locally advanced GB. [Table: see text]

Abstract BackgroundAcute respiratory failure associated with sepsis contributes to higher in-hospital mortality. Intubation and invasive mechanical ventilation is a common rescue procedure. However, the 2016 International Guidelines for Management of Sepsis and Septic Shock does not provide any recommendation on indication nor timing of intubation. Timely intubation may improve outcome. The decision to intubate those patients is often hampered by the fear of further hemodynamic deterioration following intubation. MethodsThis study aimed at evaluating the impact of timely intubation on outcome in sepsis associated respiratory failure. We conducted an ancillary analysis of a prospective registry od adult ICU patients with septic shock admitted to the medical ICU in a tertiary medical center, between April 30th, 2014 and December 31st, 2017. All cases of sepsis with lactate >4 mmol/L, mean arterial pressure <65 mmHg, or vasopressor use after 30 mL/kg fluid boluses and suspected or confirmed infection. Patients who remained hospitalized at 24 hours following sepsis onset were separated into intubated and non-intubated groups. The primary outcome was hospital mortality. Univariate and multivariable analyses were used, adjusted for admission characteristics and stabilization of shock within 6 hours. In a secondary analysis, time-dependent propensity score matching was used to match intubated and non-intubated patients.ResultsWe identified 345 (33%) patients intubated within 24 hours and 707 (67%) not intubated. Intubated patients were younger, transferred more often from an outside facility, had higher severity of illness scores, more lung infection, achieved blood pressure goals more often but less often lactate normalization within 6 hours. The crude in-hospital mortality was higher, 89 (26%) vs. 82 (12%), p<0.001, as were ICU mortality, and ICU and hospital length of stay. After adjustment, intubation showed no effect on hospital mortality but fewer hospital-free days through day 28. After 1:1 propensity score matching, there was no difference in hospital mortality, but fewer hospital-free days in the intubated group. ConclusionsIntubation within 24 hours of sepsis onset was safe and not associated with hospital mortality, but was associated with less 28-day hospital-free days. Intubation should not be discouraged in appropriate patients with septic shock.

The Impact

Background Few population-based studies assess the impact of cancer on sepsis incidence and mortality. Objectives To evaluate epidemiological trends of sepsis in patients with cancer. Methods This retrospective cohort study included adults (≥20 years old) identified using sepsis-indicator International Classification of Diseases codes from the Nationwide Inpatient Sample database (2006-2014). A generalized linear model was used to trend incidence and mortality. Outcomes in patients with cancer and patients without cancer were compared using propensity score matching. Cox regression modeling was used to calculate hazard ratios for mortality rates. Results The study included 13 996 374 patients, 13.6% of whom had cancer. Gram-positive infections were most common, but the incidence of gram-negative infections increased at a greater rate. Compared with patients without cancer, those with cancer had significantly higher rates of lower respiratory tract (35.0% vs 31.6%), intra-abdominal (5.5% vs 4.6%), fungal (4.8% vs 2.9%), and anaerobic (1.2% vs 0.9%) infections. Sepsis incidence increased at a higher rate in patients with cancer than in those without cancer, but hospital mortality rates improved equally in both groups. After propensity score matching, hospital mortality was higher in patients with cancer than in those without cancer (hazard ratio, 1.25; 95% CI, 1.24-1.26). Of patients with sepsis and cancer, those with lung cancer had the lowest survival (hazard ratio, 1.65) compared with those with breast cancer, who had the highest survival. Conclusions Cancer patients are at high risk for sepsis and associated mortality. Research is needed to guide sepsis monitoring and prevention in patients with cancer.

Abstract Background: Patients with Barcelona Clinic Liver Cancer (BCLC) stage B hepatocellular carcinoma (HCC) are recommended to undergo transcatheter arterial chemoembolization (TACE). However, TACE in combination with radiofrequency ablation (RFA) is not inferior to surgical resection (SR), and the benefits of surgical resection (SR) for BCLC stage B HCC remain unclear. Hence, this study aims to compare the impact of SR, TACE+RFA, and TACE on analyzing overall survival (OS) in BCLC stage B HCC. Methods: Overall, 428 HCC patients were included in BCLC stage B, and their clinical data and OS were recorded. OS was analyzed by the Kaplan-Meier method and Cox regression analysis. Results: One hundred forty (32.7%) patients received SR, 231 (53.9%) received TACE+RFA, and 57 (13.3%) received TACE. The OS was significantly higher in the SR group than that in the TACE+RFA group [hazard ratio (HR): 1.78; 95% confidence incidence (CI): 1.15-2.75, p=0.009]. The OS was significantly higher in the SR group than that in the TACE group (HR: 3.17; 95% CI: 2.31-4.36, p<0.0001). Moreover, the OS was significantly higher in the TACE+RFA group than that in the TACE group (HR: 1.82; 95% CI: 1.21-2.74, p=0.004). The cumulative OS rates at 1, 3 and 5 years in the SR, TACE+RFA, and TACE groups were 89.2%, 69.4% and 61.2%, 86.0%, 57.9% and 38.2%, and 69.5%, 37.0% and 15.2%, respectively. After propensity score matching, the SR group still had a higher OS than those of the TACE+RFA and TACE groups. The TACE+RFA group had a higher OS than that of the TACE group. Conclusion: The SR group had higher OS than the TACE+RFA and TACE groups in BCLC stage B HCC. Furthermore, the TACE+RFA group had higher OS than the TACE group.

Background The aim of this study was to compare the outcomes of a primary and secondary Bentall-De Bono procedure. Methods From 2008 to 2015 (8-year period), 308 patients underwent a Bentall-De Bono procedure in our institute. The mean age was 43 ± 13 years and 80% were men. Twenty-eight patients had prior cardiac surgery through a median sternotomy (group 1) and 280 underwent a primary Bentall-De Bono procedure (group 2). Various preoperative and perioperative parameters were analyzed before and after propensity-score matching. Results Before propensity-score matching, patients undergoing a secondary Bentall-De Bono procedure had a worse preoperative profile, as indicated by a higher EuroSCORE II ( p < 0.0001), with hospital mortality in group 1 of 14% (4/28) and 5% (14/280) in group 2 ( p = 0.069). After propensity-score matching, there was no significant difference in EuroSCORE II ( p = 0.922) or hospital mortality ( p = 0.729). After adjusting for the different variables, repeat sternotomy could not be identified as an independent predictor of postoperative mortality or morbidity. Survival at the end of 1 and 5 years in both groups showed no significant differences before or after propensity-score matching ( p = 0.328 and p = 0.356, respectively). In Cox multivariable regression analysis, reoperation was not identified as an independent factor for survival before ( p = 0.559) or after propensity-score matching ( p = 0.365). Conclusion A secondary Bentall-De Bono procedure can be performed with acceptable mortality and morbidity, and with midterm survival rates comparable to those of a primary Bentall-De Bono procedure.

Perioperative Blood Transfusion

Abstract Background Microvascular thrombosis has been associated with cytokine release and inflammatory syndromes which can occur as a result of blood transfusions. This phenomenon could potentially lead to complications in breast free flap reconstruction. The aim of this study was to evaluate the impact of perioperative blood transfusion in free flap breast reconstruction using large population analysis. Methods The American College of Surgeons National Quality Improvement Program database was queried for delayed free flap breast reconstructions performed in 2016. The study population was divided based on perioperative blood transfusion within 24 hours of the start of the operation. Propensity score matching analysis was used to ensure homogeneity between the two study groups. Primary outcome was unplanned return to the operating room (OR) within 30 days. Secondary outcomes were readmission and complications. Results A total of 1,256 patients were identified. Out of those, 91 patients received a perioperative blood transfusion. All the patients received only one unit of PRBC within the first 24 hours. Those patients were matched with similar patients who did not receive a transfusion on a ratio of 1:3 (273 patients). Patients who received a transfusion had a significantly higher incidence of reoperation (42 vs. 10%, p < 0.001). Patients who received a transfusion were more likely to return to the OR after 48 hours from the initial operation (13 vs. 5%, p = 0.001). All returns to the OR were due to flap-related complications. Perioperative blood transfusion increased the incidence of wound dehiscence (9 vs. 2%, p = 0.041) but had no protective effect on the development of other postoperative complications. Conclusion Perioperative blood transfusion in free flap breast reconstruction is associated with an increased probability of flap-related complications and subsequent return to the OR without decreasing the probability of developing other systemic postoperative complications.

The Impact

We aimed to evaluate the impact of alternating lenvatinib (LEN) and trans-arterial therapy (AT) in patients with intermediate-stage hepatocellular carcinoma (HCC) after propensity score matching (PSM). This retrospective study enrolled 113 patients with intermediate-stage HCC treated LEN. Patients were classified into the AT (n = 41) or non-AT group (n = 72) according to the post LEN treatment. Overall survival (OS) was calculated using the Kaplan–Meier method and analyzed using a log-rank test after PSM. Factors associated with AT were evaluated using a decision tree analysis. After PSM, there were no significant differences in age, sex, etiology, or albumin-bilirubin (ALBI) score/grade between groups. The survival rate of the AT group was significantly higher than that of the non-AT group (median survival time; not reached vs. 16.3 months, P = 0.01). Independent factors associated with OS were AT and ALBI grade 1 in the Cox regression analysis. In the decision tree analysis, age and ALBI were the first and second splitting variables for AT. In this study, we show that AT may improve prognosis in patients with intermediate-stage HCC. Moreover, alternating LEN and trans-arterial therapy may be recommended for patients below 70 years of age with ALBI grade 1.
