picibanil and Adenocarcinoma--Papillary

Eleven patients with liver metastasis from gastric cancer were treated by intermittent arterial infusion using OK-432 and recombinant IL-2 in combination with anticancer drugs. The direct effects for liver metastasis were PR 3 (response rate 30%), MR 2, NC 3, PD 1 and NE 1. Papillary adenocarcinoma showed a highly effective rate. The mean survival period was 326 days and the 50% survival period was 318 days. Out of 4 patients who underwent surgical resection for metastatic liver tumor, one showed recurrence, and the other is now healthy without any sign of recurrence for 8 years after the operation. In 7 patients with liver metastasis from colorectal cancer, intermittent arterial infusion therapy using Leucovorin, CDDP and 5-FU was performed. The direct effects were CR 2, PR 1, MR 1, PD 2, NE 1; the mean survival period was 478 days, and the 50% survival period 556 days. Out of 8 patients who underwent liver resection for metastasis, all patients remained alive for 687 mean survival days without liver recurrence. No severe side effects were noted in either therapy.

We explored whether the stimulation of iodine uptake by interferons seen in rat thyroid cell line is reproducible in human thyroid cancer and thus applicable to enhance the efficacy of radioiodine therapy.. Surgical specimens from 12 papillary and 2 follicular adenocarcinomas were minced and seeded in culture trays. After 14-16 days in a medium supplemented with 5% calf serum, we measured cellular uptake of 125I during a 40-min incubation period.. In 8 of 12 papillary and all 2 follicular carcinomas, interferon-gamma significantly stimulated iodine incorporation. The four nonresponder tumors had lower basal iodine uptake and relatively less differentiation of histologic features. The effect was dose dependent (0-100 U/ml), and the average maximum increase in responding cases was 35.1% over basal values. Tumor necrosis factor-alpha alone did not alter uptake, but at 300 U/ml it further enhanced the effect of interferon-gamma in the two follicular tumors. In addition to the pure cytokines, supernatant from lymphocyte culture conditioned with a bacterial immunostimulator also boosted radioiodine trapping in thyroid cancer cells.. These in vitro results warrant animal experiments to test potential usefulness of tumoricidal cytokines in radioiodine therapy.

A 70-year-old male with unresectable stage IV gastric cancer was locally administered OK-432 on operation. During the 3rd year following the operation, primary lesion was notably reduced by endoscopic picture, and ro cancerous tissue was detected by biopsy. In addition, serum levels of AFP and CEA were markedly decreased. The patient has survived for 3 years 6 months after operation.

Reported herein is the case of a terminal patient with advanced gastric cancer who was shown an extremely effective response to immunochemotherapy. The patient, a 62-year-old female, was determined as having a gastric cancer, Borr. type 2, originating in the pyloric antrum. The tumor was found to be H3P3S2N2 (stage IV), and its histology revealed a mucus-producing papillary adeno-carcinoma, ss gamma, n(+), ly2, and V1. Thus the patient underwent a distal gastrectomy, and was given an operative administration of MMC, followed by postoperative immunochemotherapy with FT 207 and OK 432. Consequently, no ascites were noticed throughout the recuperative course, and repeated CT scannings of the hepatic metastatic lesions, revealed a remarkable regression. Two years after this operation, she resumed normal daily life. Further, her preoperatively elevated tumor markers have returned to normal.

A combination of MFC (Mitomycin-C, 5-FU and Cytosine arabinoside) was administered to 32 gastric cancer patients and study was made of the therapeutic efficacy in relation to the histological pattern. In evaluation based on the degree of cancer cell infiltration (INF), chemotherapy was more effective in cases with INF alpha and beta than those with INF gamma. As for the grade of follicular hyperplasia in regional lymph nodes of gastric cancer, the higher was the grade, the more effective was the chemotherapy. However, a significant relationship could not be observed between histological pattern of stromal reaction of the gastric cancer and clinical effects of chemotherapy. The grade of lymphocyte infiltration or connective tissue reaction in the stroma was not related with the therapeutic effects. No relationship was also obtained between the grade of sinus histiocytosis of lymphoid reaction in the lymph nodes and therapeutic effects.
