Cancer patients with tuberculosis easy

The study, cancer and pulmonary tuberculosis may be specific reasons: ① malignant tumor itself can inhibit the patient's immune function: ② tumor cells can produce immunosuppressive factors: ③ surgery, radiotherapy, chemotherapy and hormone use, such as drug treatment will be further damage to the patient's immune function. According to statistics, in clinical lung cancer with the possibility of tuberculosis than other malignancies, the incidence is about 1 to 2 per cent. Cancer patients with tuberculosis, if the clinical symptoms and results of imaging examination typical, can be found in sputum Mycobacterium tuberculosis, the positive tuberculin test, can easily be diagnosed. Conversely, patients with the disease can easily be misdiagnosed as suffering from lung metastasis and patients with diseases such as lung infection. It is particularly worth mentioning is that when lung cancer patients with tuberculosis, because of these two diseases in patients with symptoms and signs were not specific, and the lung cancer and tuberculosis X-ray findings also quite similar, so these patients can easily be misdiagnosed . In short, if it is active in patients with malignant tumors of cancer or anti-infection treatment, their lungs will be a difficult primary lung cancer and pulmonary metastases interpretation of the imaging examination results, there must be vigilant against the possibility of pulmonary tuberculosis, and TB sputum should do so promptly; and the tuberculin test examination. If two patients with malignant tumors of this inspection were negative but it was highly suspected to be tuberculosis, but also for diagnosis of anti-tuberculosis treatment.
