This prospective, controlled study evaluated the safety, tolerability, and efficacy of the mixture of botanical compounds known as LCS101 in preventing chemotherapy-induced hematological toxicity in breast cancer patients.


Female patients diagnosed with localized breast cancer were randomly allocated to receive treatment with either LCS101 or placebo capsules, in addition to conventional chemotherapy. The study intervention was initiated 2 weeks prior to the initiation of chemotherapy and continued until chemotherapy was completed, with participants receiving 2 g of LCS101 capsules thrice daily. Subjects were assessed for the development of hematological and nonhematological toxicities, as well as the tolerability and safety of the study intervention.


Sixty-five breast cancer patients were recruited, with 34 allocated to LCS101 and 31 allocated to placebo treatment. Patients in the treatment group developed significantly less severe (grades 2-4) anemia (p < .01) and leukopenia (p < .03) when comparing grades 0-1 with grades 2-4, with significantly less neutropenia (p < .04) when comparing grades 0-2 with grades 3-4. This effect was more significant among patients undergoing a dose-dense regimen. No statistically significant effect was found with respect to nonhematological toxicities, and side effect rates were not significantly different between the groups, with no severe or life-threatening events observed in either group.


The addition of LCS101 to anthracycline- and taxane-based chemotherapy is safe and well tolerated, and may significantly prevent some chemotherapy-induced hematological toxicities in early breast cancer patients. These results should encourage further larger and more extensive clinical trials.
