Abstract:

In recent years， the incidence of idiopathic pulmonary fibrosis in patients with lung cancer increased year by year. However， the diagnosis and treatment of idiopathic pulmonary fibrosis with lung cancer （IPF-LC） is difficult because of the lack of specific clinical manifestations， hematological and imaging features. IPF-LC patients often can not tolerate chemotherapy due to poor pulmonary function and other reasons， so the treatment options are limited. On the other hand，radiotherapy, chemotherapy and targeted treatment will increase the process of pulmonary fibrosis， leading to the treatment difficulties and poor prognosis. This study aims to summarize the epidemiology， pathogenesis， clinical features and treatment of IPF-LC.
