Analysis of Gastrointestinal Core Symptoms and Influencing Factors in Postoperative Chemotherapy Patients with Gastric Cancer
Abstract
Background Gastrointestinal symptoms in gastric cancer patients treated with postoperative chemotherapy are diverse and interconnected, without effective intervention targets. In recent years, network analysis has emerged as a prominent approach to identify intervention targets. Objective To construct a network of gastrointestinal symptoms in gastric cancer patients treated with postoperative chemotherapy, identify core symptoms and analyze the factors influencing core symptoms, so as to provide a reference for precise symptom management. Methods Postoperative chemotherapy patients with gastric cancer were selected in the medical oncology and surgical oncology department of four tertiary A-level Chinese medicine hospitals (Jiangsu Provincial Hospital of Traditional Chinese Medicine, Suzhou Hospital of Traditional Chinese Medicine, Wuxi Hospital of Traditional Chinese Medicine, and Xuzhou Hospital of Traditional Chinese Medicine) in South, Central, and North of Jiangsu Province, from March to December 2022 via convenience sampling method, as the study subjects. The MD Anderson Symptom Inventory Gastrointestinal Cancer (MDASI-GI) was used for evaluating gastrointestinal symptoms and their severity among patients receiving postoperative chemotherapy for gastric cancer, as well as assessing the classification of traditional Chinese medicine constitution among patients. The network of gastrointestinal symptoms was constructed using an R package to identify the centrality indexes. The univariate analysis and multiple linear regression analysis were conducted to investigate factors influencing core gastrointestinal symptoms in patients undergoing postoperative chemotherapy for gastric cancer. Results A total of 362 electronic questionnaires were collected, 355 were valid, with a valid recovery rate of 98.1%. The highest incidence of gastrointestinal symptoms in patients with postoperative chemotherapy for gastric cancer was lack of appetite (83.1%), taste alteration (81.7%) and nausea (71.0%), and the top three in terms of severity were lack of appetite (2.77 points), taste alteration (2.50 points) and nausea (2.27 points). Network analysis showed that taste alteration had the highest intensity (rS=1.27) and the highest tight centrality (rC=1.50) ; vomiting had the highest betweenness centrality (rB=1.76). The results of multiple linear regression analysis showed that gender (B=0.809, 95%CI=0.319-1.298), smoking history (B=0.706, 95%CI=0.185-1.228) and phlegm-damp constitution (B=1.703, 95%CI=0.538-2.868) were the factors influencing the severity of taste alteration symptoms in patients with gastric cancer after chemotherapy (P<0.05) . Conclusion Taste alteration is the core symptom of gastrointestinal symptoms in gastric cancer patients undergoing postoperative chemotherapy. Gender, smoking history, and phlegm-damp constitution are influential factors contributing to taste alteration. Nursing staff can develop intervention strategies based on these core symptoms and their influencing factors to enhance the efficacy of managing gastrointestinal symptoms during chemotherapy in gastric cancer patients.
