The opposite observation in patients with DM was presented by Zhang [ 4 ]. From this group patients developed cancer after the diagnosis of dermatomyositis.

Polymyositis and dermatomyositis as a risk of developing cancer

Polymyositis was diagnosed in patients, of whom had cancers. In 95 cases of PM the cancer diagnosis was established after the diagnosis of PM.

The authors concluded that DM is strongly associated with malignant polymyositis y dermatomyositis and PM increases the risk of cancers [ 5 ]. Surgical treatment in patients with DM and lung cancer in some cases may significantly reduce symptoms of DM and may lead to recovery from DM also in patients previously resistant to pharmacological treatment [ 6 ].

Endometrial cancer is the most common cancer of the reproductive organs in the United States; there are about 40, new cases per year [ 7 ].

Risk factors include older age, diabetes, and conditions with increased levels of estrogen: The most common symptom of endometrial cancer is bleeding after menopause. The first case of stomach cancer associated with symptoms of DM was presented in by Stertz [ 8 polymyositis y dermatomyositis.

Since then, numerous case reports have shown that they are much more common in women over 50 years of age in conjunction with cancer of the ovary, lung, pancreas, stomach and colon, and lymphomas. However, ovarian cancer appears to be most closely connected with dermatomyositis, and the relationship of other cancers of the reproductive organ with PM and DM is relatively weak.

Frequency of specific cancer types in dermatomyositis and polymyositis: a population-based study.

Bladder cancer transitional cell carcinoma — TCC may be associated with various paraneoplastic syndromes manifesting as endocrine, neuromuscular, or hematological disorders, and paraneoplastic DM secondary to cancer of the bladder TCC is rarely observed [ 9 ].

The relationship between systemic connective tissue diseases and the development of skin cancer is based on disorders polymyositis y dermatomyositis the immune system, inflammation, application of immunosuppression and increased susceptibility to viral infections.

Additional causes include environmental factors such as UV radiation and smoking. The identification of patients at high risk polymyositis y dermatomyositis cancer remains a priority in the diagnosis and treatment of these patients.

On the other hand, the presence of interstitial lung disease, arthritis, Raynaud's syndrome, or anti-Jo-1 antibody indicates less than average risk of developing cancer.

The presence of antibodies to extractable nuclear antigens anti-ENA seems to be associated with reduced risk of cancer. Recently three new DM-specific polymyositis y dermatomyositis, which may be important in predicting the risk of developing cancer, have been discovered: The distribution polymyositis y dermatomyositis ILD lesions was evaluated in four divided lung zones of high-resolution computed tomography images.

As independent risk factors for early death, extended ILD lesions in upper lung fields odds ratio OR 8.

The independent risk factors were high serum KL-6 OR 3. Conclusion The present study shows the progression of ILD at baseline is the most critical for survival and that infection, especially respiratory infection, is an additive prognostic polymyositis y dermatomyositis under the potent immunosuppressive treatment.


Electronic supplementary material The online version of this article doi: Dermatomyositis, Polymyositis, Interstitial lung disease Background Polymyositis PM and polymyositis y dermatomyositis DM are idiopathic inflammatory myopathies IIM of unknown causes, which are often associated with extramuscular manifestations such as interstitial lung disease ILDarthropathy, cardiomyopathy, and malignancies.

ILD is categorized according to histopathological findings into usual interstitial pneumonia, non-specific interstitial pneumonia NSIPorganizing pneumonia, diffuse alveolar damage, respiratory bronchiolitis, desquamative interstitial pneumonia, and lymphoid interstitial pneumonia.
