Clinical diagnosis and treatment and prognosis of appendiceal neoplasms / 中华普通外科杂志

ABSTRACT

Objective:To analyze the pathogenesis and clinical characteristics of appendiceal neoplasms and its prognosis.Methods:In recent 14 years, 94 appendiceal neoplasms were found among 6 334 patients undergoing appendectomy in a single center of Ordos Central Hospital.The initial symptoms, clinical features, auxiliary examinations, pathology, surgical methods, and clinical outcomes of 94 patients diagnosed with appendix tumors were recorded.Results:Appendiceal neoplasms accounted for 1.48% for all undergoing appendectomy. Among these 94 cases, 49 cases were female and 45 cases were male. The median age was 59.5 years. 80 cases were followed up with a follow-up rate of 85.1%, and the follow-up period was 2-175 months.The 5-year overall survival rate was 91.9% and the 10-year overall survival rate was 88.9%.The results of univariate analysis of prognosis showed that the prognosis of patients with WBC count>10.0×10 9/L (χ 2 =8.884, P=0.003) and lymph node metastasis(χ 2 =17.216, P=0.001) was relatively poor. The prognosis of appendiceal adenocarcinoma is relatively poor compared with mucinous tumors(χ 2=13.857 , P=0.001 ). Conclusions:The incidence of appendiceal neoplasms is very low; Chronic lower right abdominal pain accounted for a large proportion of the manifestations; Classification of appendiceal neoplasms, leukocyte count and lymph node metastasis predict the prognosis of patients with appendiceal neoplasms.
