Objectives: The study aims to evaluate the therapeutic efficacy and safety of Chinese herbal medicine (Xiaoaiping) injections for chemotherapy-induced thrombocytopenia (CIT) in nonsmall cell lung cancer (NSCLC) and gastric cancer. Design: A randomized, controlled, multicenter study from December 2013 to August 2015. Settings/Location: All patients are from China. Subjects: One hundred forty patients with either NSCLC or gastric cancer were enrolled in this trial. Interventions: The intervention group (n = 70) was given Xiaoaiping injections (1 dose/day for 10 days) with chemotherapy, whereas the control group (n = 70) was given chemotherapy only. The follow up period was 11 days after the final injection. Outcome measures: Platelet (PLT) count was tested at day 0, 7, 14, and 21 as the primary outcome for evaluation. Safety measurements, including red blood cells (RBC), hemoglobin (HBG), white blood cells (WBC), neutrophil (NE)#, aspartate aminotransferase (AST), alanine aminotransferase (ALT), lactate dehydrogenase (LDH), creatine kinase (CK), creatinine (Cr), and blood urea nitrogen (BUN) were tested at day 0 and 21 as the secondary outcomes. Results: (1) Two patients in the intervention group and four patients in the control group were lost upon follow-up. (2) PLT count: there was no significant difference in PLT count between the two groups from baseline (day 0), day 7, and day 14. At day 21, the intervention group indicated an upward trend of PLT count with a statistically significant difference than that of the control group (p < 0.05). (3) NSCLC: there was significant difference in PLT count between the two groups on day 21 (p < 0.01). (4) Gastric cancer: there was no significant difference in PLT count between the two groups during this trial (p > 0.05). (5) There was no statistically significant difference between the intervention group and the control group with the safety figures (secondary outcomes) RBC, HGB, WBC, NE#, AST, ALT, LDH, CK, Cr, and BUN measured (p > 0.05). (6) Adverse events: one gastric cancer patient in the control group was diagnosed with gastrointestinal bleeding on day 3. Conclusions: In conclusion, Xiaoaiping injections may provide a safe and effective option for CIT in patients with NSCLC.
