Value of lymphocyte reactivity induced by phytohemagglutinin in the treatment of malignant diseases.
An improved micromethod for evaluating in vitro lymphocyte blastogenetic activity, a modification of the method of Park and Good, is devised and used in 111 stomach cancer, 34 colorectal cancer, and 22 breast cancer cases. Follow-up information on the lymphocyte blastogenetic activity levels was available in 28 stomach cancer patients after the clinically complete removal of the tumor. In 16 patients with early stomach cancer the lymphocyte blastogenetic level did not differ greatly from a control values from healthy volunteers. However, in 66 advanced stomach cancer cases, statistically lower levels were encountered. After the complete removal of the tumor in 28 stomach cancer patients, the lymphocyte blastogenetic values rose postoperatively. The lymphocyte blastogenetic levels in patients with curative colorectal cancer or curative breast cancer were significantly higher than those patients with non-curative tumors.
