Analysis of the Clinical Characteristics of Malignant Tumor Patients with Rheumatic Symptoms and Rheumatic Disease Combined with Malignant Tumor Patients
Objective: We study the relationship between rheumatic immune disease and malignant tumor to provide the basis for clinical diagnosis and treatment. Methods: We selected 53 patients who were hospitalized in our department from January 2013 to February 2020, including 26 patients with rheumatic immune disease combined with malignant tumor and 27 patients with malignant tumor with rheumatic symptoms. We retrospectively analyzed the relationship between gender, age, main clinical manifestations, tumor system distribution, metastasis rate, rheumatic immune disease type and tumor type. Results: Among the patients with rheumatic immune disease complicated with tumor, 26.1% were male and 66.7% were female. Among the tumor patients with rheumatic symptoms, 73.9% were male and 33.3% were female. There was a significant difference in gender composition between the two groups. Among the patients with rheumatic immune disease complicated with tumor, respiratory system tumor was the highest. Among the tumor patients with rheumatic symptoms, the incidence of hematological tumors was the highest. The distribution of tumor system was different between the two groups. The proportion of metastatic tumor in patients with rheumatic symptoms is higher than that in patients with rheumatic immune disease combined with malignant tumor. The percentage of concurrent tumor in three diseases in the same period was 0.363% for rheumatoid arthritis, 2.02% for polymyositis/ dermatomyositis and 0.24% for Sjogren's syndrome. This study shows that patients with polymyositis/ dermatomyositis are more likely to develop malignant tumors. Conclusion: There were significant differences in gender composition, distribution of tumor system and the proportion of metastatic tumor between patients with rheumatic immune disease complicated with malignant tumor and patients with rheumatic symptoms, and malignant tumor was more common in patients with polymyositis/ dermatomyositis
