Abstract: As a result of research work and investigations relating to the effect of benzaldehyde on cell membranes, it was found that benzaldehyde has high activity in the treatment of selected malignant conditions. Based on this finding, we have now completed the present invention directed to a composition comprising benzaldehyde as the active ingredient. This composition is effective against selected malignant conditions which are carcinoma of the colon, cancer of the stomach, cancer of the tongue, peritonitis carcinomatosa, cancer of the liver and malignancies induced by SF.sub.40 virus.

Abstract: Disclosed is a novel carcinostatic composition comprising 4,6-0-benzylidene-D-glucopyranose as the active ingredient. This active ingredient exerts a very high carcinostatic activity according to a specific carcinostatic mechanism quite different from that of conventional carcinostatic chemotherapeutic agents. The active ingredient is very low in toxicity and is highly stable and water-soluble. This composition is effective against selected malignant conditions which are carcinoma of the colon, cancer of the stomach, cancer of the tongue, peritonitis carcinomatosa, cancer of the liver and malignancies induced by SV.sub.40 virus.
