Adjuvant treatment of operable stomach cancer with polyadenylic.polyuridylic acid in addition to chemotherapeutic agents: a preliminary report.
A randomized trial of polyadenylic.polyuridylic acid [poly(A).poly(U)] in addition to chemotherapy was undertaken in patients with stomach cancer following curative gastrectomy. They were randomized into a group of 108 patients receiving chemotherapy plus poly(A).poly(U) and a control group of 116 patients receiving chemotherapy alone. Chemotherapy consisted of injections of 5-fluorouracil, 12 mg/kg once weekly and adriamycin, 40 mg/m2 once every 3 weeks, continuously after operation. Poly(A).poly(U) was infused in a 100 mg dose, once a week six times from 5 days after the first injection of chemotherapeutic agents and 6 months later in a half dose similarly. At 55 months after initiation of the trial, the mean follow-up periods were 24 months for both groups. It has been revealed that patients who received the combined treatment postoperatively showed a lesser mortality and lower rate of recurrence, both reflecting significant increases in overall (P less than 0.05) and relapse-free (P less than 0.02) survivals as compared to those who received chemotherapy alone. This effect is more pronounced in patients having moderately advanced lymphnode involvement (N1) than in patients without (N0) or more advanced (N2) involvement. Thus, poly(A).poly(U) appears to be an effective agent when used postoperatively with chemotherapy in stomach cancers.
