Small cell lung cancer (SCLC) is a kind of disease with high degree of malignancy and poor prognosis.Based on the effectiveness of systemic chemotherapy, the treatment of primary lesions and whole brain radiotherapy can bring survival benefits to patients with extensive stage small cell lung cancer.Patients with liver metastasis have a worse prognosis than those with other organ metastases.Local radiotherapy for patients with liver metastasis may have a better prognosis.However, clinical data of the safety and efficacy of whole liver radiotherapy for liver metastasis are still lacking.The purpose of this prospective study is to evaluate the safety, efficacy, and tolerability of liver metastatic radiotherapy in small cell lung cancer (SCLC).
The aim of this randomized study is to investigate local tumor control,survival outcomes and complications on patients of liver metastasis in small cell lung cancer.
