Long-Term Outcome of Proximal Gastrectomy for Upper-Third Advanced Gastric and Siewert Type II Esophagogastric Junction Cancer Compared With Total Gastrectomy: A Propensity Score-Matched Analysis.

ABSTRACT:

Background

This study aimed to investigate the oncologic long-term safety of proximal gastrectomy for upper-third advanced gastric cancer (AGC) and Siewert type II esophagogastric junction (EGJ) cancer.

Methods

The study enrolled patients who underwent proximal gastrectomy (PG) or total gastrectomy (TG) with standard lymph node (LN) dissection for pathologically proven upper-third AGC and EGJ cancers between January 2007 and December 2018. Propensity score-matching with a 1:1 ratio was performed to reduce the influence of confounding variables such as age, sex, tumor size, T stage, N stage, and tumor-node-metastasis (TNM) stage. Kaplan-Meier survival analysis was performed to analyze oncologic outcome. The prognostic factors of recurrence-free survival (RFS) were analyzed using the Cox proportional hazard analysis.

Results

Of the 713 enrolled patients in this study, 60 received PG and 653 received TG. Propensity score-matching yielded 60 patients for each group. The overall survival rates were 61.7 % in the PG group and 68.3 % in the TG group (p = 0.676). The RFS was 86.7 % in the PG group and 83.3 % in the TG group (p = 0.634). The PG group showed eight recurrences (1 anastomosis site, 1 paraaortic LN, 1 liver, 1 spleen, 1 lung, 1 splenic hilar LN, and 2 remnant stomachs). In the multivariate analysis, the operation method was not identified as a prognostic factor of tumor recurrence.

Conclusion

The patients who underwent PG had a long-term oncologic outcome similar to that for the patients who underwent TG for upper-third AGC and EGJ cancer.

Project description:BackgroundThe surgery of adenocarcinoma of the esophagogastric junction (AEG) is a complex procedure that increases postoperative morbidity compared to distal gastric cancer. In this study, we included thoracic anatomical parameters of patients for the first time to investigate their impact on the postoperative outcomes of transabdominal gastrectomy for Siewert type II/III AEG.MethodsAll patients with Siewert type II or III AEG of our institution who underwent transabdominal proximal or total gastrectomy from January 2015 to December 2022 were included in this study. We measured thoracic anatomical parameters on the level of the lower edge of the sternum using preoperative computer tomography. The anteroposterior diameter of the thorax was measured as the distance from the posterior edge of the sternum to the anterior edge of the spine, while the transverse diameter was the maximum distance between the ribs on both sides. Patients' data and postoperative details were retrospectively collected. Correlation between thoracic anatomical parameters with postoperative complications were analyzed.ResultsOverall, 647 patients were eligible for this study. The incidence of postoperative complications was 28.1%, with postoperative pulmonary complications occurring in 24.7%. In multivariate analysis, anteroposterior thoracic diameter > 10.2 cm was an independent risk factor for postoperative complications (OR = 1.891, 95% CI: 1.137-3.146, p = 0.014), transverse thoracic diameter > 23.3 cm was an independent risk factor for postoperative pulmonary complications (OR = 2.243, 95% CI: 1.234-4.079, p = 0.004). In open group, transverse thoracic diameter over 23.3 cm correlated independently with postoperative complications (OR = 2.451, 95% CI: 1.219-4.927, p = 0.012) and postoperative pulmonary complications (OR = 2.988, 95% CI: 1.407-6.347, p = 0.004). However, this correction was not significant in laparoscopy-assisted group.ConclusionsThoracic size is an independent risk factor affecting the postoperative outcomes of transabdominal gastrectomy for Siewert type II and III AEG. Patients with larger thoracic cage are at a higher risk of postoperative complications, particularly pulmonary complications. For those patients, laparoscopic surgery may be a viable option.
