817. ARTERIA LUSORIA: IMPLICATIONS FOR ESOPHAGEAL SURGERY

Abstract Background The aberrant right subclavian artery, also known as arteria lusoria, is an embryologic abnormality affecting 0.5-1.8% of individuals. Instead of arising from the brachiocephalic artery, the right subclavian artery emerges as the fourth branch of the aortic arch. In most cases (80%), the artery has a retro-esophageal trajectory, while in 20% it runs anteriorly, which may pose difficulties in performing a safe intra-thoracic or cervical anastomosis. This condition is associated with a non-recurrent right inferior laryngeal nerve. Methods Following Kurokawa’s publication in 2019, our unit has adopted routine recurrent bilateral laryngeal nerve lymphadenectomy in esophageal and cardia carcinomas with over than 4 cm of esophageal involvement. We present a video that features a 68-year-old male diagnosed with a squamous cell carcinoma of lower thoracic esophagus, staged as cT3N+M0. He presents with a retro-esophageal arteria lusoria and non-recurrent right inferior laryngeal nerve. Following the CROSS protocol with neoadjuvant chemoradiotherapy, the patient underwent a Mckeown esophagectomy with total thoracic lymphadenectomy. Results In this presentation, we explore the anatomical details and surgical considerations associated with the arteria lusoria in esophageal surgery. This video details the essential procedural steps for the identification of the vagus nerve and the identification of the arteria lusoria during upper mediastinal dissection. This case emphases the need for customized surgical strategies and the role of interdisciplinary collaboration, particularly integration of radiological insights. Such cooperation ensures that the surgical team is ready to address the unique challenges presented by these anatomical deviations and minimize the risks. Conclusion In conclusion, this presentation aims to highlight the procedural intricacies and the collaborative effort required to manage effectively the arteria lusoria in esophageal surgery. https://drive.google.com/file/d/1agjPmA6lxPoVVPxvgJCHaDCqs1dJP-xk/view

Risk of Second Primary Cancer Among Patients with Cardio-Esophageal Cancer in Finland: A Nationwide Population-Based Study.

The occurrence of a second primary cancer (SPC) after primary esophageal carcinoma (EC) or gastric cardia carcinoma(GCC) is well acknowledged. However, previous research on the risk of SPC among these patients has been predominantly conducted in Asian countries. Yet, notable population-dependent variation in histological types and risk profiles exists. This register-based study assesses the histology-specific risk of SPC among individuals initially diagnosed with a first primary EC or GCC. We obtained data on 7197 patients diagnosed with EC/GCC in Finland between 1980 and 2022 from the Finnish Cancer Registry. Standardized incidence ratios (SIR) of SPC were subsequently calculated relatively to the cancer risk of the general population. The average and median follow-up times were 2.8 years and 10.5 months. Adenocarcinomas and squamous cell carcinomas comprised 57.8% (n = 4165) and 36.6% (n = 2631) of all cases, respectively. An increased SIR was noted among EC/GCC patients after 15-20 years of follow-up (SIR 1.49, 95% CI: 1.01-2.11). Among adenocarcinoma patients, an increased SIR for SPCs of the digestive organs was seen in the 40-54-year-old group (SIR 9.86, 95% CI: 3.62-21.45). Squamous cell carcinoma patients displayed increased SIRs for cancer of the mouth/pharynx (SIR 3.20, 95% CI: 1.17-6.95) and respiratory organs (1.77, 1.07-2.76). Healthcare professionals should be aware of the increased risk of SPCs occurring in the mouth/pharynx, respiratory and digestive organs in survivors of EC/GCC. Patients should be advised about this risk and remain alert for symptoms, even beyond the standard 5-year follow-up period.

Construction and testing of a risk prediction classifier for cardia carcinoma.

This research aimed to construct a prediction model for stages II and III cardia carcinoma (CC), and provide an effective preoperative evaluation tool for clinicians. CC mRNA expression matrix was obtained from Gene Expression Omnibus and The Cancer Genome Atlas databases. Non-negative matrix factorization was used to cluster data to obtain subgroup information, and weighted gene co-expression network analysis was used to uncover key modules linked to different subgroups. Gene-set enrichment analysis analyzed biological pathways of different subgroups. The related pathways of multiple modules were scrutinized with Kyoto Encyclopedia of Genes and Genomes. Key modules were manually annotated to screen CC-related genes. Subsequently, quantitative real-time polymerase chain reaction assessed CC-related gene expression in fresh tissues and paraffin samples, and Pearson correlation analysis was performed. A classification model was constructed and the predictive ability was evaluated by the receiver operating characteristic curve. CC patients had four subgroups that were associated with brown, turquoise, red, and black modules, respectively. The CC-related modules were mainly associated with abnormal cell metabolism and inflammatory immune pathways. Then, 76 CC-elated genes were identified. Pearson correlation analysis presented that THBS4, COL14A1, DPYSL3, FGF7, and SVIL levels were relatively stable in fresh and paraffin tissues. The area under the curve of 5-gene combined prediction for staging was 0.8571, indicating good prediction ability. The staging classifier for CC based on THBS4, COL14A1, DPYSL3, FGF7, and SVIL has a good predictive effect, which may provide effective guidance for whether CC patients need emergency surgery.

Association analysis of apoptosis-related gene caspase3, Integrin a subunit 1 and glutathione sulfur transferase M1 gene polymorphisms and susceptibility to gastric cardia carcinoma.

To explore the association of polymorphisms of apoptosis-linked genes caspase3 (CASP3), integrin a subunit 1 (ITGA1), glutathione sulfur transferase M1 (GSTM1) with susceptibility to gastric cardia carcinoma (GCC). From February 2016 to March 2018, selection of 113 GCC patients was as the gastric cancer (GC), and selection of 75 patients without gastric disease was as the control. Detection of CASP3, ITGA1 and GSTM1 gene polymorphisms in patients' peripheral blood was to analyze their association with GC. Division of the GC was into the good prognosis and the unpleasing prognosis in the light of the survival of patients after surgery of 3 years, and the predictable value of gene polymorphisms of CASP3, ITGA1 and GSTM1 in GCC patients was analyzed. CASP3 gene rs12108497 locus, ITGA1 gene rs1862610 locus and GSTM1 genotype of the GC and the control were in accord with Hardy-Weinberg equilibrium (P > 0.05); The detection rate of CASP3 gene rs12108497 locus TC/CC type, ITGA1's gene rs1862610 locus AC/AA type and GSTM1 blank type in the GC was elevated vs. the control (P < 0.05); Logistic regression analysis manifested smoking, anxiety, helicobacter pylori infection, family history of gastrointestinal tumor, combination with chronic gastric disease, CASP3 gene and GSTM1 gene polymorphism were risk factors for GC (P < 0.05); Stratification was in the light of individual smoking status, discovering that the detection rates of CASP3 gene rs12108497 locus TC/CC type, ITGA1 gene RS1862610 locus AC/AA type and GSTM1 blank type in the smoking were crucially augmented vs. the smoking (P < 0.05); The detection rates of CASP3 gene rs12108497 locus TC/CC type, ITGA1 gene rs1862610 locus AC/AA type and GSTM1 blank type in the death were augmented vs. the survival (P < 0.05); Combined detection of CASP3, ITGA1 and GSTM1 gene polymorphisms was provided with predictive value for GCC's prognosis (P < 0.05). CASP3 and GSTM1 genes are susceptibility genes for GCC, which might be associated with the occurrence of GCC in smoking patients, and the joint detection of multiple genes is provided with predictive value for patients' prognosis.

Case Report: Differential lung ventilation with jet ventilation via a bronchial blocker for a patient with a large thoracogastric airway fistula after esophagectomy

A thoracogastric airway fistula (TGAF) is a rare and potentially fatal complication of esophagectomy for esophageal and cardia carcinomas. Isolation of the fistula and pulmonary separation is necessary during the surgical repair of a tracheal fistula. However, currently, the reported airway management techniques are not suitable for patients with a large TGAF. This case study presents an alternative technique for performing differential lung ventilation in a patient with a thoracogastric airway fistula. A 70-year-old man was diagnosed with a thoracogastric airway fistula situated above the carina after esophagectomy, and a thoracoscope-assisted repair of the fistula and pectoralis major myocutaneous flap transplantation were scheduled. The patient could not tolerate one-lung ventilation and the complex intubating operation due to aspiration pneumonia and the size (3.5 cm × 1.7 cm) of the fistula. We, therefore, performed differential lung ventilation in which an extended 6.5#single-lumen endotracheal tube was inserted into the left main bronchus and a 9Fr bronchial blocker was placed in the right main bronchus by using the video-flexible intubation scope. The right lung was selectively inflated with jet ventilation, while positive pressure ventilation was maintained through the left endotracheal tube. The value of SPO2 remained above 95% throughout the operation. For patients with a large thoracogastric airway fistula, differential lung ventilation of a combination of positive pressure ventilation and jet ventilation is useful. Inserting an extended single-lumen endotracheal tube into the left main bronchus and a bronchial blocker into the right main bronchus could be another way of providing differential ventilation for patients with a large thoracogastric airway fistula.

Transthoracic, thoracoabdominal, and transabdominal surgical approaches for gastric cardia adenocarcinomas: a survival evaluation based on a cohort of 7103 patients

BackgroundThis study compared the survival outcomes of different surgical approaches to determine the optimal approach for gastric cardia adenocarcinoma (GCA) and aimed to standardize the surgical treatment guidelines for GCA.MethodsA total of 7103 patients with GCA were enrolled from our previously established gastric cardia and esophageal carcinoma databases. In our database, when the epicenter of the tumor was at or within 2 cm distally from the esophagogastric junction, the adenocarcinoma was considered to originate from the cardia and was considered a Siewert type 2 cancer. The main criteria for the enrolled patients included treatment with radical surgery, no radio- or chemotherapy before the operation, and detailed clinicopathological information. Follow-up was mainly performed by telephone or through home interviews. According to the medical records, the surgical approaches included transthoracic, thoracoabdominal, and transabdominal approaches. Kaplan–Meier and Cox proportional hazards regression models were applied to correlate the surgical approach with survival in patients with GCA.ResultsThere were marked differences in age and tumor stage among the patients who underwent the three surgical approaches (P < 0.001). Univariate analysis showed that survival was related to sex, age, tumor stage, and N stage (P < 0.001 for all). Cox regression model analysis revealed that thoracoabdominal approach (P < 0.001) and transabdominal approach (P < 0.001) were significant risk factors for poor survival. GCA patients treated with the transthoracic approach had the best survival (5-year survival rate of 53.7%), and survival varied among the different surgical approaches for different tumor stages.ConclusionThoracoabdominal approach and transabdominal approach were shown to be poor prognostic factors. Patients with (locally advanced) GCA may benefit from the transthoracic approach. Further prospective randomized clinical trials are necessary.

Combined risk factors and risk of upper gastrointestinal cancer mortality in the Linxian general population.

We aimed to explore the association of combined risk factors with risk of death from upper gastrointestinal (UGI) cancer, including esophageal squamous cell carcinoma (ESCC), gastric cardia carcinoma (GCC) and gastric noncardia carcinoma (GNCC) in the Linxian Nutrition Intervention Trial (NIT) cohort. The NIT cohort included 29 584 healthy adults. A combined risk score (CRS) was calculated using a point system method based on 10 risk factors collected at baseline, including gender, smoking, alcohol drinking, body mass index, family history of UGI cancer, drinking tap water, tooth loss and consumption of fresh fruit, eggs and meat. Possible score ranged from 0 to 31, and higher score indicated as poorer health status. Subjects were divided into three groups by the CRS (<12 points, 12 to 20 points and >20 points). The group of CRS <12 points was considered as the reference. During the 30-year follow-up, we identified 4553 UGI cancer deaths. Compared to subjects with a CRS <12 points, the adjusted HRs for CRS of 12 to 20 points and >20 points were 1.69 (95% CI: 1.56-1.83) and 3.06 (95% CI: 2.82-3.33) for UGI cancer mortality, respectively (Ptrend < .001). Comparable associations were also observed for ESCC, GCC and GNCC mortality. Results remained similar across different age groups (Pinteraction > .05). All HRs observed in the second half follow-up period were stronger than that observed in the first half follow-up period. Our study indicated that higher CRS was associated with increased risk of UGI cancer mortality. Appropriate measures should be taken to reduce unhealthy lifestyles.

The Association Between Family History of Upper Gastrointestinal Cancer and the Risk of Death from Upper Gastrointestinal Cancer-based on Linxian Dysplasia Nutrition Intervention Trial (NIT) Cohort.

ObjectiveExplore the influence of family history of upper gastrointestinal (UGI) cancer on UGI cancer death, based on the Linxian Dysplasia Nutrition Intervention Trial (NIT) cohort.MethodsFamily history of UGI cancer was defined as at least one first-degree relative (parent, child, or sibling) had a history of esophageal or gastric cancer. Cancer death was carried out by ICD-10 code. Family history information was collected at baseline and cancer deaths were assessed at each annual follow-up. The COX proportional risk model was used to estimate the hazard ratio (HR) and 95% confidence interval (95% CI). We compared the positive family history group with the negative to determine the risk of family history on UGI cancer death. The effect of category of relatives, number of relatives with UGI cancer, and diagnosis age of relatives on the UGI death risk were further analyzed. Interaction and stratification analyses were done to see the subgroup effects. Sensitivity analyses were also conducted by exclusion of individuals who were followed up less than three years. We considered controlling of covariates including: gender, age (continuity), community, education level, number of siblings (continuity), BMI (continuity), smoking, alcohol use, fresh fruit intake, fresh vegetable intake, hot beverage intake, edible oil intake, meat intake, and moldy staple food intake. All food intake variables were converted into categorical variables.ResultsFrom1985 to2015, we followed up total 3,318 individuals with 898 UGI cancer deaths (537 from ESCC, 77 from GNCC, and 284 from GCC). In a single factor analysis, family history of UGI cancer increased the risk of death of esophageal squamous cell carcinoma (ESCC) by 27% (HR=1.270, 95%CI1.072-1.504). No associations were observed in gastric cardia carcinoma (GCC) and gastric non-cardia carcinoma (GNCC). After adjusting for multi-factor, a family history of UGI cancer risk of death increased by 31.9% from ESCC (HR=1.319,95%CI:1.110-1.567). Subgroup analysis of different types of relatives with UGI cancers, UGI cancers in the mother (HR=1.457,95%CI:1.200-1.768), brother (HR=1.522,95%CI:1.117-2.073), and sister (HR=1.999,95%CI:1.419-2.817) were independent risk factors for ESCC death, while the father was not. In addition, 2 relatives with UGI cancer (HR=1.495, 95%, CI:1.110-2.013) and ≥3 relatives with UGI cancer (HR=2.836, 95%CI:1.842-4.367) significantly increased the risk of ESCC death, and the trend test was statistically significant (P<0.001). Relatives’ diagnostic age of 51-60 years (HR=1.322, 95%CI:1.046-1.672) and 41-50 years (HR=1.442, 95%CI:1.078-1.930) were the risk factors for ESCC death, with statistical significance in the trend test (P=0.010). No statistically significant result of the family history effect on the risk of death from GCC or GNCC was found. Sensitivity analysis of 80% of subjects, randomly selected, did not change the results.ConclusionA family history of UGI cancer may predict the risk of death from ESCC but not from GCC or GNCC. UGI cancer in the mother may predict the risk of death from ESCC, but not father, which indicates gender differences. Gender and smoking are the interaction items with family history in a similar extent. In the subgroup, the risk of ESCC death is more distinct by family history in younger, female, and better-lifestyle individuals, which indicates the unique role of genetic factors.

Family History and Risk of Upper Gastrointestinal Cancer in the Linxian General Population.

ObjectiveThe objective of this study was to investigate family history (FH) of upper gastrointestinal (UGI) cancer and risk of esophageal squamous cell carcinoma (ESCC), gastric cardia carcinoma (GCC), and gastric non-cardia carcinoma (GNCC) in the Linxian General Population Nutrition Intervention Trial (NIT) cohort. Methods: This prospective analysis was conducted using the Linxian NIT cohort data. Subjects with FH of UGI cancer was treated as an exposed group while the remainders were considered as a comparison group. Hazard ratios (HRs) and 95% confidence intervals (CIs) for the association between FH of UGI cancer and risk of UGI cancer incidence and mortality were estimated using Cox proportional hazards models.ResultsThere were 5,680 newly diagnosed UGI cancer cases during the follow-up period, with a total of 4,573 UGI cancer deaths occurred, including 2,603 ESCC, 1,410 GCC, and 560 GNCC deaths. A positive FH of UGI cancer was associated with a significantly increased risk of ESCC and GCC (Incidence: HRESCC = 1.45, 95%CI: 1.35–1.56; HRGCC = 1.27, 95%CI: 1.15–1.40; Mortality: HRESCC = 1.40, 95%CI: 1.30–1.52; HRGCC = 1.27, 95%CI: 1.14–1.42) after adjusting for age at baseline, gender, smoking status, alcohol drinking, education level, and frequency of fresh fruit and vegetable consumption. Subjects with FH in both parents had the highest risk of ESCC and GCC incidence (HRESCC = 1.65, 95%CI: 1.40–1.95; HRGCC = 1.42, 95%CI: 1.12–1.81) and deaths (HRESCC = 1.65, 95%CI: 1.38–1.97; HRGCC = 1.42, 95%CI: 1.09–1.85). Spouse diagnosed with UGI cancer did not increase the risk of any UGI cancers of the subjects. In subgroup analysis, FH of UGI cancer was shown to significantly increase the risk of GCC in non-drinkers (Incidence: HR = 1.31, 95%CI: 1.17–1.47; Mortality: HR = 1.33, 95%CI: 1.17–1.50). No associations were observed for risk of GNCC. Sensitivity analysis by excluding subjects who were followed up less than three years did not materially alter our results.ConclusionOur data point to the role of the FH of UGI cancer to the risk of ESCC and GCC incidence and mortality. The influence of family history on the risk of UGI cancer varies from different types of family members.

Application of mediastinal drainage tube in intrathoracic esophageal anastomotic leakage for early diagnosis and effective treatment: a retrospective study

BackgroundIntrathoracic esophageal anastomotic leakage (AL) is one of the most fatal complications after esophagectomy. In this study, we placed an additional drainage tube in the esophagus bed and evaluated its effect in early diagnosis and treatment of AL.MethodsFrom January 2010 to August 2020, 312 patients with esophageal or cardia carcinoma underwent esophageal resection with intrathoracic esophagogastric anastomosis. A total of 138 patients with only one pleural drainage tube were divided into the “Control Group” and 174 patients with a pleural drainage tube and an additional mediastinal drainage tube (MDT) were divided into the “Tube Group”. For all patients, the incidence of postoperative AL, the time to diagnosis, time to recovery, and patient outcome were analyzed.ResultsNo significant differences were observed in the AL rate (P = 0.837) and postoperative pain between two groups. However, in the Tube Group, almost all the patients were diagnosed prior to the appearance of hyperpyrexia, which was considered as the earliest and most common symptom after AL. In the Tube Group, a significant decrease was observed in the incidence of incurable fistula, which required re-operation or variable treatments under gastroscopy when compared to the Control Group (P = 0.032). Finally, patients in the Tube Group showed reduced post AL hospital day (P = 0.015) and a lower mortality, however, when compared to the Control Group, no significant differences were observed (P = 0.188).ConclusionsPlacement of an MDT does not prevent AL, but it is an effective approach for earlier diagnosis of AL and facilitates fistula healing and patient recovery.

Site-Specific Variation in Familial Cancer as Suggested by Family History, Multiple Primary Cancer, Age at Onset, and Sex Ratio Associated With Upper, Middle, and Lower Third Esophageal and Gastric Cardia Carcinoma.

BackgroundIn China, esophageal squamous cell carcinoma (ESCC) and gastric cardia adenocarcinoma (GCA) differ in terms of multiple primary cancer (MPC) and male-to-female sex ratio (MFSR).MethodsWe studied site-specific variation in familial cancer by comparing family history (FH), MPC, age at onset (AO), and MFSR among 8768 patients with ESCC/GCA.ResultsESCC/GCA patients with a positive FH are associated with a significantly higher rate of MPC and a younger AO than those without (sex-specifically: MPC 1.6% vs. 0.7%, P<0.01 and 3.2% vs. 0.8%, P<0.01; AO 53.1 ± 8.1 vs. 54.5 ± 8.2, P=0.000 and 52.9 ± 7.4 vs. 54.0 ± 8.0, P=0.005). Among patients with a positive FH, MPC decreases significantly from upper-, middle-, and lower-third ESCC to GCA (sex-specifically: 53.6%, 1.8%, 1.6%, 0.8%, P=0.000; and 71.4%, 1.5%, 2.2%, 1.6%, P=0.000). From MPC, upper-, middle-, and lower-third ESCC to GCA, AO increased sex-specifically: 51.9 ± 7.2, 52.8 ± 7.9, 52.1 ± 8.3, 54.3 ± 8.4, 55.6 ± 7.6 (P=0.000) and 49.3 ± 6.5, 51.8 ± 9.8, 52.6 ± 7.8, 54.4 ± 8.0, 55.7 ± 7.2 (P=0.000), and FH decreased: 43.8%, 35.1%, 28.2%, 29.5%, 24.4% (P=0.000) and 55.2%, 26.7%, 25.0%, 24.3%, 22.3% (P=0.000). The preponderance of males, smoking, alcohol consumption, and patients ≥50 years old increased from 2.2:1, 1.7:1, 1.0:1, 2.0:1 in ESCC to 6.1:1, 2.8:1, 2.5:1, 4.0:1 in GCA, yet more MPCs were associated with non-preponderant than preponderant counterparts; particularly in GCA, the difference was statistically significant.ConclusionThe proportion of familial cancer may decrease from upper-, middle-, and lower-third ESCC to GCA. This entails molecular investigation, and appreciating this may help us devise a better screening strategy or individualize cancer treatment.

Oral leukoplakia and the long-term risk of upper gastrointestinal cancer deaths in the Linxian dysplasia population.

BackgroundTo investigate oral leukoplakia (OL) and risk of upper gastrointestinal (UGI) cancer deaths in the Linxian Dysplasia Nutrition Intervention Trial (NIT) cohort.MethodsA total of 3318 subjects with esophageal squamous dysplasia enrolled on 1 May 1985, and were followed up until 30 September 2015. Participants with OL at baseline were treated as an exposed group, while the remainder was selected as a control group. All subjects were followed monthly and reviewed quarterly by the Linxian Cancer Registry. Cox proportional hazard model was used to estimate hazard ratios (HRs) and 95% confidence intervals (95% CIs).ResultsDuring the 30‐year follow‐up, a total of 902 UGI cancer deaths occurred, including 541 esophageal squamous cell carcinoma (ESCC) related, 284 gastric cardia carcinoma (GCC) related, and 77 gastric noncardia carcinoma (GNCC) related deaths. Relative to subjects without OL, the long‐term risk of ESCC mortality in participants with OL increased by 26.1% (HR = 1.26, 95% CI: 1.05–1.52). In the subgroup analyses, adverse effects of OL on ESCC mortality were observed especially in younger subjects (HR = 1.48, 95% CI: 1.11–1.97), females (HR = 1.44, 95% CI: 1.11–1.89), non‐smokers (HR = 1.44, 95% CI: 1.15–1.81), nondrinkers (HR = 1.28, 95% CI: 1.04–1.57), and individuals with a family history of cancer (HR = 1.37, 95% CI: 1.05–1.79). No associations were observed between OL and risk of GCC and GNCC mortality.ConclusionsOL may increase the long‐term risk of ESCC mortality, especially in younger subjects, females, nondrinkers, non‐smokers, and subjects with a family cancer history. Future studies are needed to explore the potentially etiological mechanism.

Fresh fruit consumption may decrease the long-term risk of esophageal cancer mortality: A 30-year follow-up study in the Linxian Dysplasia Nutrition Intervention trial (NIT).

BackgroundThe objective of this study was to explore the association between fresh fruit consumption and long‐term risk of upper gastrointestinal cancer (UGI) in the Linxian Dysplasia Nutrition Intervention Trial (NIT) cohort.MethodsA cohort of 3318 subjects with esophageal squamous dysplasia participated in the Linxian Dysplasia NIT in May 1985 and were followed up until 30 September 2015. Demographic characteristics, lifestyle, and history of diseases were collected at the baseline. The primary endpoint was death from esophageal squamous cell carcinoma (ESCC), gastric cardia carcinoma (GCC), and gastric noncardia carcinoma (GNCC). Hazard ratios (HRs) and 95% confidence intervals (95% CIs) were estimated using the Cox proportional hazard model.ResultsIn the 30‐year follow‐up, a total of 541 ESCC, 284 GCC, and 77 GNCC deaths occurred. Relative to those who never or rarely consumed fresh fruit, the risk of ESCC mortality in participants who consumed fresh fruit more than 12 times/year were significantly decreased by 37.3% (HR = 0.63, 95% CI: 0.49–0.81). In the subgroup analyses, significantly protective effects on ESCC mortality were observed especially in females (HR = 0.59, 95% CI: 0.40–0.89), non‐smokers (HR = 0.67, 95% CI: 0.48–0.94), and nondrinkers (HR = 0.69, 95% CI: 0.51–0.93).ConclusionsConsuming fresh fruit more than 12 times/year may reduce the long‐term risk of ESCC mortality in this dysplasia population, particularly in females, non‐smokers, and nondrinkers. Future studies are needed to confirm these findings.

Risk Factors and Prognostic Impact of Mediastinal Lymph Node Metastases in Patients with Esophagogastric Junction Cancer.

We retrospectively investigated the risk factors for mediastinal lymph node (MLN) metastasis in esophagogastric junction (EGJ) cancer with an epicenter within 2cm above and below the anatomical cardia, including both adenocarcinoma (AC) and squamous cell carcinoma (SCC). Fifty patients who underwent initial surgery for EGJ cancer from January 2002 to December 2013 were included in this study. We defined metastatic lymph nodes as pathological metastases in resected specimens and recurrence within 2years postoperatively. Thirty-four patients had AC and 16 had SCC; 24 patients underwent transhiatal resection and 26 underwent transthoracic resection. MLN metastasis was observed in 13 patients (26%) regardless of the histological type, 9 of whom had metastasis in the upper and middle mediastinum. Metastasis occurred when the esophageal invasion length (EIL) exceeded 20mm. In addition, 10/13 patients had stage pN2-3 cancer. Multivariable analysis identified EIL ≥ 20mm and stage pN2-3 as significant risk factors for MLN metastasis. The 5-year overall survival was 38% and 65% in the MLN-positive and -negative groups, respectively (p = 0.12). Multivariable Cox regression analysis showed that only stage pN2-3, and not the presence of MLN metastasis, was a significantly poor prognostic factor. MLN metastasis in EGJ cancer may have a close association with the EIL of the tumor, but the presence of MLN metastasis itself was not a poor prognostic factor. The significance and indications for MLN dissection should be clarified in prospective clinical trials.

Body mass index and risk of upper gastrointestinal cancer: A 30-year follow-up of the Linxian dysplasia nutrition intervention trial cohort

BackgroundAlthough a number of previous studies have noted the association between body mass index (BMI) and upper gastrointestinal (UGI) cancer risk, little evidence exists in the Chinese esophageal squamous dysplasia population. This prospective study investigated the association between BMI and UGI cancer risk in the Linxian Dysplasia Nutrition Intervention Trial (NIT) cohort. MethodsA total of 3298 participants were included in the final analysis. Asian-specific BMI cut-offs were used to define BMI subgroups: underweight <18.5 kg/m2, normal ≥18.5 to <24 kg/m2 and overweight or obese ≥24 kg/m2. Hazard ratios (HRs) and 95 % confidence intervals (95 %CIs) were estimated using the Cox proportional hazard model. ResultsDuring over 30 years of follow-up we identified 654 incident esophageal squamous-cell carcinoma (ESCC) cases and 434 gastric cancer cases which included 88 gastric non-cardia carcinoma (GNCC) and 346 gastric cardia carcinoma (GCC) cases. Relative to normal weight, overweight or obesity were associated with a significantly reduced risk of ESCC (HR 0.69, 95 %CI 0.48–0.98) after multivariate adjustment, including age at baseline, gender, smoking, drinking, family history of cancer, education and consumption of fresh fruit. Subgroup analyses found that clear effects were evident in women and subjects with a family history of cancer. No association with gastric cancer was observed in any subjects or subgroups. ConclusionOverweight/obesity was associated with decreased risk of ESCC in this dysplasia population, particularly in women and persons who had a family history of cancer. Future studies are needed to confirm these findings.

Characterization of 500 Chinese patients with cervical esophageal cancer by clinicopathological and treatment outcomes.

Objective: There are no comprehensive studies on survival outcomes and optimal treatment protocols for cervical esophageal cancer (CEC), due to its rare clinical prevalence. Our objective was to determine the relationship between pathological characteristics, treatment protocols, and survival outcomes in Chinese CEC patients.Methods: A total of 500 Chinese CEC patients were selected from our 500,000 esophageal and gastric cardia carcinoma database (1973–2018). There were two main groups: patients treated with surgery, and patients receiving non-surgical treatments (radiotherapy, radiochemotherapy, and chemotherapy). The Chi-square test and Kaplan–Meier method were used to compare the continuous variables and survival.Results: Among the 500 CEC patients, 278 (55.6%) were male, and the median age was 60.9 ± 9.4 years. A total of 496 patients (99.2%) were diagnosed with squamous cell carcinoma. In 171 (34.2%) patients who received surgery, 22 (12.9%) had undergone laryngectomy. In 322 (64.4%) patients who received non-surgical treatments, 245 (76.1%) received radiotherapy. Stratified survival analysis showed that only T stage was related with survival outcomes for CEC patients in the surgical group, and the outcomes between laryngectomy and non-laryngectomy patients were similar. It was noteworthy that the 5-year survival rate was similar in CEC patients among the different groups treated with surgery, radiotherapy, chemotherapy, or radiochemotherapy (P = 0.244).Conclusions: The CEC patients had similar survival outcomes after curative esophagectomy and radiotherapy, including those with or without total laryngectomy. These findings suggest that radiotherapy could be the initial choice for treatment of Chinese CEC patients.

Mycotic aortic aneurysm as a postsurgical complication: report of a case and review of the literature

Mycotic aneurysms are localized and irreversible dilatations of the arteries caused by weakening and damaging the arterial wall by an invasive organism establishing infective arteritis. Mycotic aneurysm of the thoracic aorta is a rare event; however, it can be fatal if not diagnosed early or not treated appropriately. Clinical findings are usually nonspecific; however, contrast-enhanced computed tomography (CT) is a common imaging modality of choice for the detection of mycotic aneurysms. Current management consists of antibiotic therapy and surgical treatment or endovascular interventions as early as possible. Herein, we present a case report of mycotic aneurysm of the thoracic aorta as a postoperative complication in a 60-year-old female with a clinical history of the cardia and esophageal carcinoma who underwent thoracic surgery. The presence of mycotic aneurysm was detected after performing a contrast-enhanced thoracic CT scan

P13 DIFFERENCE IN LONG-TERM QUALITY OF LIFE BETWEEN MCKEOWN AND IVOR LEWIS ESOPHAGECTOMY

Abstract Aim The purpose of this study was to investigate the difference in long-term health-related quality of life (HR-QoL) between McKeown and Ivor Lewis esophagectomy in a tertiary referral center. Background &amp; Methods The therapy of esophageal cancers consist of (neo)adjuvant chemo(radio)therapy and surgery. Often different surgical approaches are possible such as transthoracic esophagectomy with a cervical anastomosis (McKeown) or an intrathoracic anastomosis (Ivor Lewis). Evidence is scarce on whether either of these approaches is better in terms of survival, perioperative morbidity, pathology results and quality of life. Patients with mid-, distal esophageal, gastroesophageal (GEJ) or cardia carcinoma who have undergone a McKeown or an Ivor lewis esophagectomy in the period of 2003 – 2018 were included in this study. EORTC QLQ-C30 and EORTC QLQ-OG25 questionnaires were handed out during the outpatient clinic visits and a follow-up of at least one year was ensured. Problems with eating, reflux and nausea and vomiting were chosen as primary HR-QoL domain endpoints while the remaining HR-QoL domains, postoperative complications and pathology results were observed as secondary endpoints. Correction for confounders age and gender was performed. Results 147 patients were included in the McKeown group and 120 in the Ivor Lewis group. Mean age was 63.5 years and median follow-up was three years (range 12-137 months). No significant difference was found in problems with eating, reflux and nausea and vomiting. Significantly more problems with eating with others were found in McKeown group (β=10.435, 95% CI 4.474 – 16.395) and anastomotic leakage was significantly more common after McKeown esophagectomy (p=0.004). No significant difference was found in Clavien Dindo classification. During Ivor Lewis esophagectomy significantly more lymph nodes were resected (p&lt;0.001). Number of lymph node metastases and R0 resection rate did not differ between groups. Conclusion No major differences in long-term HR-QoL were found in patients with mid-, distal esophageal, GEJ or cardia carcinoma following McKeown or Ivor Lewis esophagectomy. Problems with eating with others and anastomotic leakages were more common after McKeown esophagectomy, however, Clavien Dindo classification and radicality of surgery were similar between the two groups. Results of this study could assist the patient during the decision-making process prior to the surgery.

P12 LONG-TERM QUALITY OF LIFE AFTER TOTAL GASTRECTOMY VERSUS IVOR LEWIS ESOPHAGECTOMY

Abstract Aim The aim of this study was to investigate the difference in long-term health-related quality of life in patients undergoing total gastrectomy versus Ivor Lewis esophagectomy in a tertiary referral center. Background &amp; Methods Surgical treatment for gastroesophageal junction (GEJ) cancers is challenging. Both a total gastrectomy and an esophagectomy can be performed. Which of the two should be preferred is unknown given the scarce evidence regarding effects on surgical morbidity, pathology, long-term survival and health-related quality of life (HR-QoL). From 2014 to 2018, patients with a follow-up of &gt; 1 year after either a total gastrectomy or an Ivor Lewis esophagectomy for GEJ or cardia carcinoma completed the EORTC QLQ-C30 and EORTC QLQ-OG25 questionnaires. Problems with eating, reflux and nausea and vomiting were chosen as the primary HR-QoL endpoints. The secondary endpoints were the remaining HR-QoL domains, postoperative complications and pathology results. Multivariable linear regression was applied taking confounders age, gender, ASA classification and neoadjuvant therapy into account. Results 30 patients after gastrectomy and 71 after Ivor Lewis esophagectomy with a mean age of 63 years were included. Median follow-up was two years (range 12-84 months). Patients after total gastrectomy reported significantly less choking when swallowing and coughing (β=-5.952, 95% CI -9.437 – -2.466; β=-13.084, 95% CI -18.525 – -7.643). Problems with eating, reflux and nausea and vomiting were not significantly different between the two groups. No significant difference was found in postoperative complications or Clavien-Dindo grade. Significantly more lymph nodes were resected in esophagectomy group (p=0.008). No difference in number of positive lymph nodes or R0 resection was found. Conclusion After a follow-up of &gt; 1 year choking when swallowing and coughing were less common after total gastrectomy. No significant difference was found in problems with eating, reflux or nausea and vomiting nor in postoperative complications or radicality of surgery. Based on this study no general preference can be given to either of the procedures for GEJ cancer. Patients may be informed about the HR-QoL domains that are likely to be affected by the different surgical procedures, which in turn may support shared decision making when a choice between the two treatment options is possible.
