Purpose: Positive margins are reported in from 4.8 to 9.5% of all gastric cancer surgeries and they have a negative impact on the overall survival. Few cases with positive duodenal margins have been included in previous studies regarding the prognosis.

Methods: This multi-institutional retrospective study included 115 gastric cancer patients with positive duodenal margins following gastrectomy between January 2002 and December 2017. The association between clinicopathological factors and the overall survival was evaluated by univariate and multivariate analyses.

Results: The three-year overall survival was 22% and the median survival was 13 months. A multivariate analysis found that distant metastasis, no postoperative chemotherapy, and non-Type 4 disease were significantly associated with a poor survival. Patients without distant metastasis who received postoperative chemotherapy had a 3-year overall survival of 56% and a median survival of 44 months.

Conclusion: The patients who underwent post-operative chemotherapy showed a significantly better OS compared with those who did not undergo post-operative chemotherapy, regardless of the existence of distant metastasis. Postoperative chemotherapy may, therefore, improve the prognosis of surgically treated gastric cancer patients with positive duodenal margins.

Gastric cancer (GC) is an aggressive tumor type with an intricate pathogenesis and limited therapeutic options. Ubiquitin-specific protease 22 (USP22) is a protein implicated in cell proliferation, metastasis, and tumorigenesis. However, the regulatory mechanisms governing USP22 in GC are still not fully understood.

Objective: This study aimed to develop an automated method for segmenting spleen computed tomography (CT) images using a deep learning model to address the limitations of manual segmentation, which is known to be susceptible to inter-observer variability. Subsequently, a prediction model for gastric cancer (GC) differentiation was constructed alongside radiomics, and a nomogram was generated to investigate its clinical guiding significance.

Methods: This study enrolled 262 patients with pathologically confirmed GC.
