This analysis indicated that patients with cancer-related pain account for 71.0% in author's material. After the TCM treatment, the effective rate were 91.6% in hepatocarcinoma-related pain; 86.1% in colon-rectal cancer-related pain; 68.2% in malignant lymphoma-related pain; 100% in irradiation-related pain of esophageal cancer, lung cancer, post-operative breast cancer. Results of "four-step analgesic ladder" showed that 52.1% of pain could be relieved by Step I (TCM therapy); if Step II (indomethacin) or III (phenylbutazone) was added, the rate of pain relief reached as high as 96.5%; and only 3.5% need to be treated by Step IV (Opioids). With less side-effects and addiction of opioids and other narcotics, the "four-step analgesic ladder" therapy seems to be more suitable for cancer pain relief in China.

Phosphotyrosine-containing proteins in various human cancer cell lines were studied by immunoblotting with anti-phosphotyrosine antibody. Of 29 cell lines derived from oral epidermoid cancer, esophageal cancer, gastric cancer, colon cancer, pancreatic cancer, hepatocellular carcinoma and malignant melanoma, 3 of the 6 gastric cancer cells showed aberrant elevation of tyrosine-specific phosphorylation. On the other hand, both esophageal cancer cells and colon cancer cells, which were reported to have amplified epidermal growth factor receptor and activated p60v-src kinase, respectively, showed no apparent elevation of tyrosine-specific phosphorylation, and their profiles of phosphorylation were similar to that of normal human fibroblasts. Two gastric cancer cells, NUGC-4 and MKN-45, showed similar profiles of phosphorylation but their responses to growth factors differed from each other. Tyrosine phosphorylation in NUGC-4 was strongly activated by treatment with epidermal growth factor and quickly reduced by the acid treatment which is effective in removing growth factors from cellular surface receptors. On the contrary, phosphorylation in MKN-45 did not respond to either growth factor or acid treatment. These results suggest that NUGC-4 and MKN-45 have tyrosine kinases which are activated by different mechanisms but share similar substrates.

Novel immunotherapeutic strategies for combating colon cancer are also being explored in pancreatic, hepatic, and esophageal cancers. Preliminary clinical trials in patients with pancreatic cancer suggest a therapeutic role for anti-idiotypic antibodies against tumor-specific monoclonal antibodies (MoAbs)--eg, CO17-1A, BW 494/32--but not for MoAbs when used alone. Adding low doses of interferon gamma to CO17-1A enhances in vitro antibody-dependent cellular cytotoxicity against pancreatic tumor cells; CO17-1A plus a regimen of 5-FU/doxorubicin/mitomycin has resulted in beneficial therapeutic effect. Treatments with immunotoxins, radiolabeled MoAbs, and adoptive immunotherapy are still being tested preclinically. In 105 patients with unresectable hepatocellular cancer, a 7% complete and 41% partial regression rate with 131I-labeled antiferritin has been reported. In several patients, radiolabeled antiferritin caused sufficient shrinkage of lesions to permit curative resection. Pretreatment with low-dose doxorubicin may improve the efficacy of low-dose radiolabeled antiferritin antibody therapy. Chemoembolization of primary hepatocellular carcinoma, based on the concept of regional therapy for metastatic colorectal cancer, has shown considerable palliative and survival benefit in patients with unresectable disease. Although adoptive immunotherapy has been used to treat hepatocellular carcinoma, the results have been disappointing. The development of immunotherapeutic approaches to esophageal cancer is less advanced than that for other gastrointestinal malignancies. Paralleling the successful use of 5-FU/interferon alfa-2a in colon cancer are two phase II studies that have evaluated this combination in patients with locally advanced esophageal cancer. The objective response rate (27%) was encouraging.

A sandwich enzyme immunoassay was set up to measure tumor associated antigen (antigen PA8-15) detected by monoclonal antibody PA8-15. The cut-off value was set at 55 U/ml. Tests on 437 sera samples from patients with malignant or benign diseases yielded the following positive percentages: esophageal cancer, 9.1%; gastric cancer, 23.1%; colorectal cancer, 44.8%; hepatoma, 32.6%; biliary tract cancer, 47.5%; pancreatic cancer, 84%; lung cancer, 30.8%; breast cancer, 16%; benign diseases, 13.2%. Positive antigen PA8-15 levels in patients with gastric, colorectal and pancreatic cancers, increased with the progression of clinical stage. When antigen PA8-15 was monitored in 11 various cancer cases before and after surgery, a decrease in PA8-15 value was revealed in all resected patients postoperatively, whereas a more than 100% increase in PA8-15 values was noted in non-resected patients. Compared with CEA and CA19-9, the highest positive PA8-15 rate was seen in pancreatic cancer patients. By combining the rates of positive sera obtained with each tumor marker, the overall percentage increased. These results suggest that measuring serum PA8-15 levels will aid in serological cancer diagnoses, particularly pancreatic cancer.

Serum levels of CA 125 and markers reputed as specific for cancers in relevant locations (squamous cell carcinoma, SCC, carcinoembryonic antigen, CEA, CA 19.9, alpha-fetoprotein, AFP) were determined in 107 patients with gastrointestinal (GI) carcinomas. The aim of this study was to assess their individual and combined sensitivities, and the power of CA 125 in excluding primary ovarian epithelial cancer from GI primary. Serum CA 125 levels (in U/ml) ranged from nondetectable to 400 in patients with esophageal, to 570 in those with gastric, and to 300 in patients with colorectal carcinoma. The levels for liver secondaries, pancreatic, and hepatocellular carcinoma were 480, 2,720 and 1,100 U/ml, respectively. Serum SCC antigen was elevated in all patients with esophageal cancer, CEA or CA 19.9 in 52% of patients with gastric cancer and in 63% with liver secondaries, and CEA in 95% of patients with colorectal cancer; whereas serum CA 125 above 65 U/ml was found in 25% of this subgroup, but only in those with already an elevated concentration of specific marker(s). Serum CEA or CA 19.9 was elevated in 71%, CA 125 in 59% of patients with pancreatic cancer; the latter mostly in those with already elevated CEA or CA 19.9. Serum AFP was elevated in 84% and CA 125 in 40% of patients with hepatoma; the latter mostly in those with already an elevated AFP. CA 125 values exceeding 1,000 U/ml were found in 1 patient with pancreatic cancer (2,720 U/ml) and in 2 with hepatoma (1,050 and 1,100 U/ml). These findings illustrate the nonspecificity of the CA 125 antigen, its small if any advantage compared to the specific markers, and they diminish its role as a marker for primary ovarian cancer from GI primary unless it exceeds 2,800 U/ml.

An autopsied case of an esophageal cancer metastasizing to a primary hepatocellular carcinoma is reported. Histologically, the esophageal cancer revealed a moderately differentiated squamous cell carcinoma and hepatocellular carcinoma was determined as being an Edmondson Type I, arranged predominantly in a trabecular pattern, and was not concomitant with liver cirrhosis. Metastasis of one malignant tumor to another in the same individual is extremely rare. In most cases, such tumors metastasize to a renal cancer, because the kidney has a rich vascularity with an abundant blood supply. Thus we presumed that the esophageal cancer had metastasized to a hepatocellular carcinoma, due to this rich vascularity, though no liver cirrhosis was found in the recipient host tumor.

A case of triple cancer involving a tubular adenocarcinoma of the stomach, a squamous cell carcinoma of the esophagus, and hepatocellular carcinoma of the live is reported. These three cancers had been diagnosed while the patient was alive and later were confirmed by autopsy. The esophageal cancer and hepatocellular carcinoma were found almost simultaneously, 6 years after surgery for the gastric cancer. Although many cases of triple cancer have been reported, a triple cancer of this combination is very rare (0.3% of all cases of triple cancer), our case being the fifth such case in Japan.

Monoclonal antibody (A9-84) against a hepatocellular carcinoma cell line (PLC/PRF-5) was produced by somatic cell fusion. The hybridoma clones were screened by a rapid solid-phase enzyme-linked binding assay. The target cells were cultured in 96-well Linbro plate and fixed by methanol for screening. The specificity of the antibody was studied by enzyme-linked binding assay and immunofluorescence methods. It shows that A9-84 do not respond to 8 different human cancer cell lines (4 liver cancer, 1 esophageal cancer, 1 stomach cancer, 1 multiple myeloma and 1 lymphoblast cell line) and the peripheral mononuclear cells of 91 normal subjects. A9-84 is the subtype of IgG3. It is capable of inhibiting the growth of cultured PLC/PRF/5 cells with or without complement.

This clinical study was undertaken in order to evaluate the effect of CDDP on 43 patients with far-advanced or recurrent carcinoma of the gastrointestinal tract. For all these patients, CDDP at 100 mg/m2 had been administered by continuous intravenous infusion for 24 hours and repeated one to seven times at an interval of 3 to 4 weeks. The effect of this therapy was assessed according to the criteria of clinical evaluation of chemotherapy for solid cancers by Koyama and Saito. The response rate for both complete and partial response was 27.9% among all 43 patients, including 47.1% (8/17) for gastric cancer, 33.3% (1/3) for esophageal cancer, 25.0% (1/4) for hepatocellular carcinoma, 25.0% (1/4) for carcinoma of the gallbladder or bile duct, 20.0% (1/5) for pancreatic cancer and none (0/10) for colorectal cancer. In particular, a good response rate of 37.5% (3/8) was obtained for patients with recurrent tumor and one of 33.3% (6/18) for those with palliative resection of the primary tumor, which was much higher that the rate of 17.6% (3/17) for those without resection. As for the side effects of CDDP therapy, gastrointestinal symptoms were most frequently found in 78.3% of patients followed by bone marrow suppression in 15.2%, and abnormalities of hepatic and renal function in 4.3% and 4.3%, respectively. Consequently, 24-hour continuous intravenous infusion of CDDP was considered to be effective for far-advanced or recurrent carcinoma, especially in cases of gastric cancer.

In a consecutive series of 562 patients with pathologically documented hepatocellular carcinoma (HCC), 12 patients (2.1%) were found to have a second primary malignancy elsewhere. Of these, eight were male, four female, with ages ranging from 49 to 76 years (mean 60.7 +/- 9.3 years). The associated cancers included eight cases of gastric cancers, an esophageal cancer, a stump cancer, a case of myelocytic leukemia and a histiocytic lymphoma. Eight cases had both malignancies diagnosed at the same admission. In the other four, HCC were detected after an interval of 4, 10, 12 and 39 months. Two had received previous chemotherapy or radiotherapy. Fifty percent of the 12 patients were hepatitis B surface antigen (HBsAg) positive. Their liver function tests and alpha-fetoprotein levels were consistent with those of patients with HCC alone. The results suggest that the occurrence of HCC concomitant with or arising after another primary malignancy in Taiwan is not rare.
