Prognostic factors and predictive signs of malignancy in adult dermatomyositis. A study of 32 cases

Meta-analysis of the association of dermatomyositis and polymyositis with cancer

“…Furthermore, male patients with DM and PM are more prone to develop cancer than their female counterparts. Skin lesions such as cutaneous necrosis are also positively associated with cancer, which is in agreement with the findings from several previous reports . Our analysis also demonstrated that dysphagia, one of the major complications in DM and PM, is a major risk factor for malignancy.…”

“…We did not examine creatine kinase, lactate dehydrogenase, ESR and aldolase because of significant heterogeneity among different studies. Diagnosis at older age has been suggested by others as a risk factor for cancer in DM and PM . Our analysis revealed that elderly patients are more likely to develop cancer.…”

Impact of cancer on the mortality of patients with idiopathic inflammatory myopathies by flexible parametric multistate modelling

“…Diseases of the circulatory and the respiratory systems were the other common causes of death in IIM patients with cancer, regardless of the timing of cancer diagnosis. These findings are in‐line with some studies [7, 12, 13, 16, 31, 33, 36] but contrast to other studies [9, 10, 14] where respiratory diseases were the first primary cause of death or contributed to the cause of death equally with cancer. The discrepancy could be explained by the selection of patients affected by ILD and cancer in the previous studies or the different underlying comorbidities between patients in our studies and patients in the previous studies [9, 10, 14].…”

Factors Predicting Malignancy in Patients with Polymyositis and Dermatomyostis: A Systematic Review and Meta-Analysis

“…For patients with DM only,[19], [20], [23], [24] a similar difference was observed in the pooled data of the four relevant studies (RR, 3.95; 95% CI: 2.37 to 6.57).…”
