Abstract
Objective
To explore the correlation between serum bilirubin, blood uric acid, and C-reactive protein (CRP) and the severity of chronic obstructive pulmonary disease (COPD). Methods: Patients with COPD who were admitted to our hospital between March 2020 and March 2023 were retrospectively studied. Based on whether their condition progressed to the acute exacerbation stage, they were divided into an exacerbation group (100 cases) and a stability group (100 cases). The clinical data from both groups were analysed to assess the correlations between serum bilirubin, blood uric acid, CRP, and the severity of COPD. Results: Univariate analysis indicated significant differences in the neutrophil-to-lymphocyte ratio (t = 5.678, P < 0.05), α-hydroxybutyrate dehydrogenase (t = 5.862, P < 0.05), total bilirubin (t = 4.341, P < 0.05), direct bilirubin (t = 5.342, P < 0.05), indirect bilirubin (t = 5.452, P < 0.05), blood uric acid (t = 4.698, P < 0.05), and CRP (t = 4.892, P < 0.05) between the two groups. Multivariate analysis revealed that total bilirubin, blood uric acid, and CRP were positively correlated with exacerbations of COPD (regression coefficients were 0.413, 0.354, and 0.356, respectively; P < 0.05). The evaluation of predictive value showed that the combined predictive value of these three indicators was the highest, with an AUC of 0.823 (95% CI: 0.754–0.911). Conclusion: Serum bilirubin, blood uric acid, and CRP levels are elevated in patients with acute exacerbations of COPD (AECOPD), showing good consistency in predicting the occurrence of AECOPD. The combined diagnostic value of these three indicators is greater than that of any single indicator, providing a reference for the early clinical prediction of AECOPD.

Abstract
Background
After China ended its ‘dynamic zero-COVID policy’ on 7 December 2022, a large-scale outbreak of SARS-CoV-2 Omicron infections emerged across the country. We conducted a hospital-wide prospective study to document the epidemiological characteristics of the outbreak among healthcare workers in a hospital of Chengdu, where no previous staff SARS-CoV-2 infections were detected.

Methods
All hospital staff members were invited to complete an online questionnaire on COVID-19 in January 2023, and SARS-CoV-2 infection cases were followed up by telephone in June 2023 to collect data on long COVID. Univariable and multivariable logistic regression analyses were performed to evaluate factors associated with SARS-CoV-2 infection.

Results
A total of 2,899 hospital staff (93.5%) completed the online questionnaire, and 86.4% were infected with SARS-CoV-2 Omicron. The clinical manifestations of these patients were characterized by a high incidence of systemic symptoms. Cough (83.4%), fatigue (79.8%) and fever (74.3%) were the most frequently reported symptoms. Multivariable logistic analysis revealed that females [adjusted odds ratio (aOR): 1.42, 95% confidence interval (CI): 1.07–1.88] and clinical practitioners (aOR: 10.32, 95% CI: 6.57–16.20) were associated with an increased risk of SARS-CoV-2 infection, whereas advanced age ≥ 60 years (aOR: 0.30, 95% CI: 0.19–0.49) and a three-dose COVID-19 vaccination with the most recent dose administered within 3 months before 7 December 2022 (aOR: 0.44, 95% CI: 0.23–0.87 for within 1 month; aOR: 0.46, 95% CI: 0.22–0.97 for within 1–3 months) were associated with reduced risk. Among the cases, 4.27% experienced long COVID of fatigue, brain fog or both, with the majority reporting minor symptoms.

Conclusion
Our findings provide a snapshot of the epidemiological situation of SARS-CoV-2 infection among healthcare workers in Chengdu after China’s deregulation of COVID-19 control. Data in the study can aid in the development and implementation of effective measures to protect healthcare workers and maintain the integrity of healthcare systems during challenging times such as a rapid and widespread Omicron outbreak.

5533 Background: Immunotherapy in combination with chemoradiotherapy has shown good efficacy in locally advanced cervical cancer (LACC). We report on the efficacy of neoadjuvant camrelizumab plus chemotherapy (TP) following concurrent immuno-chemoradiotherapy and maintenance immunotherapy for LACC. Methods: Eligible participants were adults with histologically confirmed squamous cell carcinoma, adenosquamous cell carcinoma, or adenocarcinoma of the cervix (FIGO 2018 stage IIB-IVA disease), ECOG PS score 0-2, and adequate bone marrow and organ function. All pts received 2 cycles neoadjuvant camrelizumab (200 mg d1 q3w) plus TP (albumin-bound Paclitaxel 260mg/m2 d1 q3w; cisplatin 75 mg/m2 d1-3 q3w) treatment, following 5-week external beam radiotherapy (EBRT) protocol (45-50 Gy/25 fractions with concurrent triweekly camrelizumab and cisplatin) to the whole pelvis plus brachytherapy every 3 weeks for 2 cycles, and then maintenance therapy of camrelizumab (200mg q3w, up to one year). The primary endpoint was progression-free survival (PFS) at 2 years. PFS was evaluated when at least 13 events were observed using a stratified log-rank test with an overall one-sided significance level of 0.05. Results: 67 pts provided informed consent and 12 were excluded for not meeting eligibility. 55 pts received the investigational agent and were evaluable for safety and efficacy analyses. The median age was 54 years [IQR 50 to 60]; 51 [92.7%] were squamous cell carcinoma, and 4 [7.3%] were adenocarcinoma; 9 [16.4%] were stage IIB, 2 [3.6%] were IIIA, 5 [9.1%] were IIIB, 30 [54.5%] were IIIC1r, 6 [10.9%] were IIIC2r, and 3 [5.5%] were IVA. As of data cutoff (Jan. 15, 2024), median follow-up was 9.5 (IQR 7.1 to 10.3) months. Of the 55 pts, 1 (1.8%) pt underwent hysterectomy after EBRT because of pelvic empyema, and was excluded from response evaluation. At three months after brachytherapy, the overall remission rate was 100% (53 [98.1%] complete remission and 1 [1.9%] partial remission). We identified 3 (5.5%) pts with treatment failure (2 [3.6] distant metastasis, and 1 [(1.8%] para-aortic lymph node relapse) during follow-up; 1-year PFS was 90.6% (85.4%-95.8%). The most common clinically significant grade 3-4 adverse events (AEs) were decreased neutrophils (18.2%), thrombocytopenia (9.1%) and anemia (27.3%). Serious AEs occurred in 7 (12.7%), most commonly due to infectious complications. There were no treatment-related deaths. Conclusions: The interim data support Camrelizumab plus TP neoadjuvant chemo-immunotherapy following immuno-chemoradiotherapy and Camrelizumab maintenance therapy as an active go-forward regimen in LACC. No new safety signals were observed, and most AEs were mild to moderate. Clinical trial information: ChiCTR2200061097.

e16100 Background: A combination of HER2-targeted therapy, immunotherapy and chemotherapy is being explored in the perioperative treatment of gastric/gastric junction (GC/GEJ) adenocarcinoma.Disitamab vedotin (RC48), a HER2-directed antibody-drug conjugate (ADC), demonstrated significant anti-tumor activity. Moreover, data suggest that the combination of RC48 with immunotherapy exhibits a synergistic effect. Therefore, we conducted the study to investigate the effects of combining RC48 with camrelizumab and S-1 in the neoadjuvant setting for locally advanced, resectable GC/GEJC with HER2 overexpression. Methods: In this prospective, phase II, single-arm study, we included patients with histologically confirmed, resectable gastric/gastric junction adenocarcinoma (GC/GEJ) staged as cT3-4aN1-3M0 according to the TNM 8th edition, and demonstrating HER2 overexpression (IHC 3+ or IHC 2+). Participants received three cycles of treatment on a three-weekly basis (Q3W). Surgical resection was scheduled to occur 3-4 weeks following the completion of neoadjuvant therapy. The primary endpoint was the pathological complete response (pCR) rate; the secondary endpoints included the major pathological response (MPR) rate, clinical downgrading rate, disease-free survival (DFS), overall survival (OS), and safety. Results: Between Sep 18, 2022 and Feb 2, 2024, a total of 23 patients were enrolled. Seven patients had not completed neoadjuvant treatment.Two patients refused surgery due to organ preservation. Two patients refused study therapy after 2 cycles of neoadjuvant treatment. 12 patients who experienced D2 resection, 6 (50%) achieved MPR, including 4 (33.3%) with pCR (ypT0N0M0).The R0 resection rate was 100%. Median DFS and OS have not been reached. The most common reported AEs (grade≥3) were decreased neutrophil count (10%), bowel obstruction (5%), ALT increased (5%) and AST increased (5%). There have been no treatment-related mortalities documented. Conclusions: The preliminary findings suggest that the neoadjuvant combination of RC48, camrelizumab and S-1 presents a promising and safe treatment option for locally advanced resectable GC/GEJ adenocarcinoma with HER2 overexpression.

e16103 Background: Surgery combined with perioperative therapy was recommended as standard treatment for patients with locally advanced esophagogastric junction (EGJ) adenocarcinoma, but the survival rate was still poor. Immunotherapy has shown antitumor activity and an acceptable safety profile in advanced EGJ cancer. The aim of this study was to evaluate the efficacy and safety of neoadjuvant Serplulimab combined with concurrent chemoradiotherapy in previously untreated locally advanced resectable EGJ adenocarcinoma. Methods: Eligible patients with resectable EGJ(Siewert Type II and Type III, Siewert classification 2000)adenocarcinoma stage cT3-4 or N+ were enrolled. Patients received neoadjuvant Serplulimab (300mg on day 1) plus SOX(oxaliplatin at 130mg/㎡on day 1; TS1 40-60mg two times per day on D1-D14, Q3W) in first cycle, followed by Serplulimab (300mg on day 1) combined with concurrent chemoradiotherapy (Reduced SOX regimen: oxaliplatin at 100mg/㎡on day 1, TS1 40-60mg two times per day on D1-D14, Q3W; Radiotherapy dose:45Gy in 25f) in second and third cycle. The patient finished the preoperative treatment and rested for 6-8 weeks for surgery. The primary endpoint was pathological complete response (pCR) rate. Secondary endpoints were major pathological response(MPR) rate, R0 resection rate, objective response rate(ORR), disease-free survival(DFS), overall survival(OS), and toxicity. Results: From March 8, 2023 to January 31,2024,15 patients were enrolled. Nine patients completed neoadjuvant therapy. Eight of these patients underwent radical surgical resection. One out of nine achieved a confirmed pathological complete response (pCR) after three cycles of neoadjuvant treatment. Additionally, two out of nine patients achieved major pathological response(MPR). So, the pCR rate was 11.1%, and the MPR rate was 22.2%. The Tumor and Lymph Nodes downstaging rates are 62.5% and 87.5%, respectively. The median DFS and OS were not reached. In terms of safety, fifteen patients who received at least one cycle of neoadjuvant therapy were included. The most common treatment-related adverse events(TRAE) across all grades were nausea/vomiting(6/15), anorexia(5/15), thrombocytopenia(4/15), and fatigue(4/15). Four patients (26.7%) had grade≥3 adverse events during preoperative therapy, with thrombocytopenia(3/15) and hepatic veno-occlusive disease(1/15). Immune-related adverse reactions(irAE) included myositis(1/15) and rash(1/15), both were grade 1. No grade 4 or higher TRAEs were observed. Conclusions: Initial benefits were demonstrated when using Serplulimab with concurrent chemoradiotherapy for the treatment of locally advanced, resectable EGJ adenocarcinoma patients. The efficacy and safety of Serplulimab with chemoradiotherapy will be further investigated in this trial later. Clinical trial information: NCT05918419 .

e16112 Background: With the aim to decrease the rate of pulmonary complications associated with thoracotomy, minimally invasive esophagectomy (MIE) was introduced. Our purpose is to see the feasibility, safety and short-term outcomes of Robot-Assisted MIE (RAMIE). Methods: Seventy-three patients of carcinoma oesophagus who underwent Robotic Esophagectomy from May 2018 to March 2023 were included. Demographic profiles, neoadjuvant therapy, and operative and postoperative outcomes were evaluated. Results: Fifty-three patients were male while 29 were female, with median age of 60 years. Four patients had a previous history of surgery for cancer, 2 had carcinoma colon, one had carcinoma breast and another had carcinoma thyroid. 71% of patients had clinical stage 3 disease and the most common location of the tumour was the middle third (62.7%). 85.3% of patients received neoadjuvant therapy. Eighty percent of our patients underwent Robotic Mc Keown’s Esophagectomy while 20% had Robotic Ivor-Lewis Operation. The thoracic part in 1 patient was converted to open due to extensive adhesions in the right hemithorax. Mean abdominal console time was 146 min (+ 32 min) and thoracic console time was 120 min (+ 39 min); with a total operative time of 314 min (+ 44 min). Intraoperative blood loss was 300 ml (+ 86 ml). Post-operative and short-term outcomes: Out of 75 patients, 74.7% patients recovered well without any major complications. The most common complications were pulmonary (16%). Anastomotic leakage was found in 8 patients of whom 4 patients were managed conservatively, 1 required oesophageal stenting, other 2 had bedside opening of neck wound and 1 required pectoralis major muscle flap cover. Clinically recurrent laryngeal nerve palsy was found in 2 patients while Chylothorax was found in 2 patients. The median ICU stay was 3 days (range 1-28 days), whereas the median hospital stay was 8 days (range 6-38 days). Our 30-day mortality was 1.3% and this patient died on POD8 due to sepsis and respiratory failure, while 90 day mortality was 4%. Oncological Outcomes: Pathological complete response was seen in 21.3% of patients and median lymph nodal yield was 21 nodes (range 9-68). There was one microscopic margin positivity. Conclusions: RAMIE is a technically feasible and safe procedure with good lymph node yield and R0 resections. Postoperative complications and short-term oncologic results are comparable to other high-volume centres.

e16116 Background: Neoajuvant chemoradiation is the standard treatment for resectable locally advanced esophageal squamous cell carcinoma (ESCC). Immune checkpoint inhibitors (ICIs) have shown a survival benefit for advanced ESCC and showed promising efficacy in neoadjuvant treatment for several cancers. This study aimed to evaluate the safety and efficacy of neoadjuvant chemoradiotherapy (nCRT) combined with sequential tislelizumab followed by surgery for resectable ESCC. Methods: This is a single-arm, phase Ib study. Eligibility criteria include histologically confirmed ESCC and clinical T3-4aN0M0 or T2-4aN+M0 (AJCC/UICC 8th). Patients received neoadjuvant radiotherapy (41.4Gy in 23 fractions) with concurrent chemotherapy (paclitaxel, 50 mg/m2, carboplatin area under the curve of 2mg/mL/min, QW*5). Then followed by two cycles of tislelizumab (200mg, Q3W). The primary endpoint was the pathological complete response (pCR) rate and safety. Results: From Feb 2022 to Jan 2024, 35 patients had been enrolled, of whom the median age was (65.5 (95%CI, 59-67), including 31 (88.6%) males. 12 patients were still undergoing chemoradiotherapy and 2 patients did not receive immunotherapy due to pneumonia and myocarditis after chemoradiotherapy. 16 patients completed all 2 cycles tislelizumab preoperatively and 5 patients completed 1 cycle tislelizumab because of AEs. Two patients refused surgery after achieved complete clinical response under radiology and were still alive, the other 19 patients underwent resection. The R0 resection rate was 94.7% (18/19). The pCR rate was 63.2% (12/19) and the MPR rate was 78.9% (15/19). During neoadjuvant treatment, 8 patients had a grade 3 or worse adverse event including leukopenia (33.3%, 7/21, Grade 3), esophagitis (4.8%, 1/21, Grade 3) and anemia (4.8%, 1/20, Grade 4). One patient developed grade 4 postoperative complication (5.3%, 1/19, pneumonia) and died within 90 days of surgery due to COVID-19. Grade 1-2 postoperative complications occurred in 21.1% (4/19) patients, including anastomotic fistula (21.1%, 4/19), chylothorax (5.3%, 1/19) and pneumonia (10.5%, 2/19). Conclusions: Preliminary results showed that neoadjuvant chemoradiotherapy (nCRT) combined with sequential tislelizumab showed promising outcomes and well tolerated for resectable ESCC patients. Further larger prospective studies are needed to confirm such findings.

Authors: Wei Meng , Yu Wenbin , Yan Zepeng 
Published: July 2024

e16117 Background: For the upper gastric cancer, especially adenocarcinoma at the esophagogastric junction, the optimal surgical method is still controversial. The purpose of the study is to evaluate the safety and clinical effect of double track (DT) anastomosis in laparoscopic radical proximal gastrectomy (LRPG). Methods: A retrospective analysis was conducted involving 243 patients who underwent LRPG in the Department of Gastrointestinal Surgery, Qilu Hospital of Shandong University from Jan. 2017 to Dec. 2020. Patients were divided into tubular esophagogastric (TG) anastomosis group and double track (DT) anastomosis group, according to the digestive tract reconstruction. Their intraoperative conditions, perioperative recovery and postoperative follow-up were compared. Patients were divided into ≥60 and < 60 groups according to age, to analysis the pros and cons of the two surgical methods in different age groups. According to whether or not indocyanine green (ICG) tracer technology was used during the operation, DT group was also divided into ICG group and non-ICG group. Results: Compared with the TG group, the DT group had less volume of gastric tube drainage, shorter gastric tube drainage time and proton pump inhibitors application time, and lower reuse rate of proton pump inhibitors. However, the DT group had more total operation time and lymph node dissection time. The median follow-up time of the patients was 36.0 months. At the end of study, the 1-year OS rate and DFS rate were 94.2% and 92.6% in the TG group and 95.8% and 93.7% in the DT group. The 3-year OS rate and DFS rate were 90.2% and 85.2% in the TG group and 91.9% and 87.7% in the DT group. And there was no significant difference in survival outcomes between the two groups. The DT group had a lower anastomotic stenosis at 3rd month after surgery. Moreover, the incidence of reflux esophagitis and Gerd Q score in the DT group were lower compared with the TG group at 3rd month, 1st year and 3rd year after surgery. In addition, elderly patients had a higher incidence of short-term complications in DT group compared with TG group. In the ICG analysis, the ICG DT group had significantly shorter total operation time and lymph node dissection time, less intraoperative blood loss and more lymph nodes obtained compared with the non-ICG DT group. Conclusions: DT anastomosis is a safe and effective way in LRPG for upper gastric carcinoma. Although the operation time of it is longer than that of TG anastomosis, it has a better anti-reflux effect and reduces the incidence of dysphagia and anastomotic stenosis. In elderly patients, it is important to minimize operative time and better to use TG anastomosis. The application of ICG tracer technique in LRPG has positive significance.

e16130 Background: Gastric cancer (GC) is one of the mostly terminal malignancies with poor prognosis. Long noncoding RNA EGOT (EGOT) acts as a crucial regulator in the breast cancer. However, the function of EGOT in GC remains unknown. Methods: This work was to explore the clinical value and biological significance of EGOT in GC. EGOT levels in GC tissue and cell were analyzed by qRT–PCR. After knockdown of EGOT, GC cell growth and cycle progression were detected. Results: The expression of EGOTwas observably elevated in GC. Upregulation of EGOT was related with lymphatic metastasis and TNM stage. In addition, knockdown of EGOT by siRNA could significantly inhibit GC cell proliferation and arrest cycle progression in G1 phase. Moreover, EGOT mediated cyclin D1 expression in GC cells which was regulated by Hedgehog pathway. Further, loss of EGOT downregulated Hedgehog signaling pathway in GC cells. Conclusions: EGOT functions as an oncogene in GC, and may be useful as a conceivable diagnostic and prognostic biomarker for GC tumorigenesis.
