mycelia extract plus adjuvant chemotherapy for breast cancer patients: Results of a randomized study on host quality of life and immune function improvement.

Anthracycline-based chemotherapies for breast cancer are known to adversely affect patients' quality of life (QOL) and immune function. For that reason, adjuvants that improve those impairments are required. A randomized double-blind study was conducted to evaluate the effectiveness of mycelia extract (LEM), which is an oral biological response modifier (BRM) medicine for cancer patients as such an adjuvant.

Relationship between cytokine gene polymorphisms and risk of postoperative pneumonia with esophageal cancer.

Background: We retrospectively evaluated the relationship between cytokine gene polymorphisms and development of postoperative pneumonia after esophagectomy.

Methods: In 120 patients who underwent esophagectomy, serum samples were obtained to measure levels of serum interleukin (IL)-6 and IL-10 at four time points (preoperatively, postoperative day (POD)0, POD1, and POD3). DNA extracted from peripheral blood in all patients was analyzed to determine polymorphisms of cytokines such as tumor necrosis factor-α -1031 T/C, IL-1β -511C/T, IL-6 -634C/G, and IL-10 -819 T/C.

Relation between cytokine promoter gene polymorphism and toxicity of 5-fluorouracil plus cisplatin chemotherapy.

Variability in the efficacies and toxicities of anticancer agents is a major problem. We hypothesized that polymorphisms in cytokine gene promoters may underlie genetic susceptibility to chemotherapy-induced toxicities in the Japanese. DNA was extracted from 100 patients undergoing 5-fluorouracil plus cisplatin chemotherapy.

[Evaluation of host immunity and side effects in breast cancer patients treated with adjuvant chemotherapy (FEC therapy)].

Background: FEC (5-FU+epirubicin+cyclophosphamide) therapy has been used as adjuvant chemotherapy for breast cancer patients with nodes positive. The aim of this study was to evaluate host immunity and side effects of the FEC therapy. The effect of oral administration of Lentinus edodes mycelia (LEM) was also observed.
