Abstract

Purpose: In recent years, lipid metabolism has been reprogrammed to meet the energy and substrate needs of tumorigenesis and development and is a potential new target for cancer treatment. However, the regulatory mechanism of lipid metabolism in esophageal squamous cell carcinoma is not well understood. Methods: We first downloaded the esophageal squamous cell carcinoma (ESCC) gene dataset in the GEO and TCGA databases and analyzed the central differentially expressed genes (DEGs) of ESCC through bioinformatics. Afterwards, the GSEA method was used to analyze the lipid metabolism-related pathway of the central gene in the pathological process of ESCC, and it was determined that the central gene OIP5 was significantly related to the fatty acid metabolism pathway. Our heatmap also revealed that the enrichment of the ACSL family in ESCC tissues was more pronounced than in normal tissues. We hypothesized that OIP5 can regulate the fatty acid metabolism process in ESCC cells and affect the tumorigenic ability of ESCC. Further statistical analysis and experiment were conducted to determine the lipid metabolism-related gene, OIP5′s, expression pattern and clinical significance in ESCC, analyze the effect of OIP5 expression on fatty acid metabolism-related enzymes in ESCC, revealing the specific mechanism of OIP5 that promotes ESCC development. Conclusions: Our study established a correlation between OIP5 expression and clinicopathological factors (tumor size, T stage, N stage, and clinical grade) in esophageal squamous cell carcinoma (p < 0.05). We have also experimentally demonstrated that OIP5 regulates ESCC fatty acid metabolism by influencing the expression of the key enzyme ACSL1 in lipid metabolism. [ABSTRACT FROM AUTHOR]

Case Report
Abstract

A 61-year-old male patient was admitted to our hospital with frequent urination, urgency, and increased nocturia for more than 3 months, and the symptoms were aggravated for 1 week. Prostate biopsy revealed prostatic adenocarcinoma. After 5 months, the patient developed dysphagia and gastroscopy showed a middle and lower esophageal cancer (squamous cell carcinoma). 12 months later, he returned to the hospital because of dysphagia. He was examined by gastroscopy which showed the cardia to have low-grade adenocarcinoma. The patient was given Casodex + Zoladex endocrine therapy, zoledronic acid inhibiting bone destruction, concurrent chemoradiotherapy, capecitabinen tablets at a dose of 1000 mg bid, 3 cycles of intravenous paclitaxel at 180 mg/d1 plus cisplatin 60 mg/d1-2, 4 cycles of intravenous paclitaxel at 150 mg/d1 plus cisplatin at 60 mg/d1 as systemic chemotherapy. The curative effect is was considerable after treatment, and the patient’s condition was stable. Since the onset of the disease in March 2018, the patient’s condition had not progressed significantly for 27 months. The diagnosis and treatment of this patient with ternary cancer in the hospital improved the clinician’s understanding of multiple primary cancers. Multidisciplinary treatment improved the patient’s prognosis and quality of life. We reviewed similar case reports and retrospective studies of multiple primary cancers and found that there is no specific treatment for multiple primary cancers, but a corresponding treatment program can be formulated for each tumor to control progression while screening for possible other primary tumors.
