Study on sentinel symptoms and influencing factors of postoperative chemotherapy in patients with gastric cancer

PURPOSE

To explore the symptom clusters of gastric cancer patients receiving postoperative chemotherapy, identify the sentinel symptom of each symptom cluster, and compare the differences in sentinel symptoms of patients for gastric cancer with different characteristics.

METHODS

This was a cross-sectional study. Patients with postoperative gastric cancer who received chemotherapy in the medical oncology department from October 2021 to July 2022 were selected for the study using a convenience sampling method.The General Information Questionnaire and the MD Anderson Symptom Inventory Gastrointestinal Cancer (MDASI-GI) were used for the survey.

RESULTS

A total of 245 patients participated in the study. There were five symptom clusters in the patients. Fatigue, nausea, sadness, and taste alteration were the sentinel symptoms of the disease symptom cluster, gastrointestinal symptom cluster, emotional symptom cluster, and neurotoxic symptom cluster, respectively. No clear sentinel symptom was found in the gastric-cancer-specific symptom cluster. Statistically significant differences were observed in fatigue, nausea, sadness, and taste alteration among patients receiving postoperative chemotherapy for gastric cancer with differences in gender, duration since diagnosis, tumor site, chemotherapy regimen, chemotherapy cycle, red blood cell count, hemoglobin level, albumin level, plasma D-dimer level, indirect bilirubin level, glutamic pyruvic transaminase level, total bile acid level, and uric acid level.

CONCLUSION

People with postoperative chemotherapy for gastric cancer experience multiple concurrent symptoms. Of the multiple symptoms that occur simultaneously, patients tend to focus on 1 or 2 symptoms of particular significance and use the occurrence of 1 symptom to explain the others. The understanding of symptom clusters and sentinel symptoms could be beneficial to assess and manage both in postoperative patients with gastric cancer during chemotherapy. Clinical staff should use sentinel symptoms as the targets for symptom cluster evaluation and effective intervention.

Advances in the application of robotic surgical systems in gastric cancer: A narrative review

Gastric cancer is one of the common malignant tumors in the gastrointestinal tract, and surgery is currently an important treatment for progressive gastric cancer. With the development of technology, the simultaneous maturation of artificial intelligence (AI), fifth-generation (5G) telecommunication networks and the internet of things (IOT) has brought significant efficacy and new opportunities for the surgical treatment of gastric malignancies. The combination of 5G network and remote surgical robotic system is the future trend of radical gastric cancer surgery, and the "unmanned" treatment mode of fully automated robotic gastric cancer radical surgery will be realized soon.

Single-stranded DNA generated by high temperature accepts protons and builds up mutagenic and carcinogenic strong acids

Malignancies are caused by genetic or environmental factors. Esophageal carcinoma can be triggered by consumption of hot food and beverages. Here we propose that high temperature is one of the culprits and it leads to DNA denaturation. Subsequently the exposed hydrogen bonding acceptors in single stranded DNA attract protons which enhance the formation of mutagenic and carcinogenic strong acids such as HCl. Faster mutation of single-stranded DNA viruses than that of double-stranded DNA viruses lends support to this theory.
