The Study of rHuTPO/rHuIL-11 in the Treatment for Chemotherapy-induced Thrombocytopenia in Patients With NSCLC

Study Overview
=================
Brief Summary
-----------------
Purpose: To evaluate the efficacy and safety of rHuTPO/rHuIL-11 in the treatment for chemotherapy-induced thrombocytopenia in patients with NSCLC receiving gemcitabine and cisplatin or carboplatin chemotherapy.

Detailed Description
-----------------
Inclusion Criteria: Patients aged 18 years -75 years, male or female; histologically or cytologically confirmed non-small cell lung cancer; consistent with the indication of chemotherapy the decrease of platelets appeared in the screen chemotherapy period and the platelet count is less than 50 * 109/ L; the expected survival was more than 3 months; patients must have the ability to understand and the willingness to sign a written informed consent; to be able to follow the study and follow-up procedures Exclusion Criteria: pregnant or lactating women; patients who had severe allergic history on biological preparation; the existing serious acute infection without control; Patients receiving radiotherapy; more than 3 metastatic tumor of bone were found in the screening period, and the platelet count did not restore to 100 * 109/ L on the screening period on the seventeenth day of the screening period; with a history of pulmonary embolism, myocardial infarction patients, thrombus history of thrombosis or activity in the past 3 months; Sepsis, disseminated intravascular coagulation (DIC); hypersplenism or any other illness sickness that can exacerbate thrombocytopenia appeared in the previous cycles of chemotherapy; tumor metastasis was found in the central nervous system;
