Glyco-polypeptides (Comosain, Bromelain) induced leucocyte binding ability to tumor surface antigens, such as interleukin 2, 6, 8, and TNFs, is known as an immuno-target therapy. Using different concentration of Bromelain proteinases in 6 types of cancer cell, it resulted in hydrolysis, fibrinolysis, necrosis, and anti-metastatic effects in tumor cells. Anti-cancer effects were achieved in carcinoma of lung, breast, colon, ovary, cervix, and uterus. Investigation of anti-metastatic effects in Bromelain were carried out in a double-blind study: low dose cohort was on 10 mg/kg/day and a high dose cohort which was on 50 mg/kg/day for a period of over six months. A total of 83 patients with 3rd and 4th stage of refractory solid tumors were enrolled, whom at least previously failed on two regimens of chemotherapy and/or failed on radiation therapy. The rates of Complete Response (CR) and Partial Responses (PR) in high dose cohort are astonishing with 52% and 27% respectively. The Progress Disease (PD) was 10%, and the Stable Disease (SD) was 11%. The implications and results of the findings are discussed with in view of the reported anti-metastatic activity of orally administrated Bromelain.
