[The Supportive Effect of Ninjin' Yoeito on Bone Marrow Function during Chemotherapy-Case Report].

Suppression of bone marrow function is one of the most common adverse effects of chemotherapy for gastrointestinal cancer. In 3 patients with gastrointestinal cancer who underwent chemotherapy, Ninjin' yoeito(NYT)was found to be effective in preventing this adverse reaction. Patient 1, a 76-year-old woman with rectal carcinoma(pT3N1bM0, pStage Ⅲb), underwent anterior rectal resection. Although chemotherapy(mFOLFOX6)was performed 6 weeks after the operation, the leukocyte and erythrocyte counts were decreased. NYT administration from day 9 of mFOLFOX6 chemotherapy resulted in the maintenance of bone marrow function and allowed continuation of chemotherapy. Patient 2 was a 65-year-old woman who underwent right hemi-colectomy for ascending colon cancer(pT3N0M0, pStage Ⅱ). A partial hepatectomy was performed for the second S8 liver metastasis, and NYT was administered at the time of introduction of mFOLFOX6. In patient 3, an 83-year-old woman who underwent total gastrectomy for gastric cancer(pT4a[SE]N3aM0, pStage Ⅲb), NYT was administered at the same time as the transition to second-line treatment with paclitaxel plus ramucirumab. In all cases, chemotherapy was continued without drug suspension or dose reduction after NYT administration. Thus, NYT may be effective in aiding the continuation of chemotherapy.
