Bloom's syndrome (BS) is an autosomal recessive disease characterized by short stature, sensitivity to sunlight, and telangiectasic malar erythema. It is associated to chromosomal breakage, to primary combined immunodeficiency, and to a high incidence of neoplasias. The authors report the case of two siblings with BS and associated immunodeficiency. Both patients were male and 5 (A) and 4 (B) years old at the time of diagnosis. Chronic diarrhea, recurrent otitis media, purulent rhinitis, conjunctivitis and pyodermatitis were reported by patient A. Patient B was admitted with diagnosis of bilateral neuroblastoma and had the tumor resected. Later on, he presented with oral moniliasis, herpetic stomatitis, and skin abscesses. This patient did not have recurrent infections. Immunological evaluation showed normal serum levels of CH50, C3, and C4 for both patients. Serum IgG, IgA, IgM, and salivary IgA levels were: 455 mg/dl, 15mg/dl, 20mg/dl, 0.6mg/dl for A, and 400mg/dl, 15mg/dl, 20mg/dl, and 0.2mg/dl for B, respectively. Serum antipolio antibodies (1, 2, and 3) were normal, and low levels of isohemagglutinins were observed in both patients. T cells subset determination showed: patient A--OKT3 = 66%, OKT4 = 33%, OKT8 = 32%, and 4/8 ratio = 1.0; patient B--OKT3 = 70%, OKT4 = 32%, OKT8 = 34%, and 4/8 ratio = 1.0. In vitro cellular immune response to PHA was depressed only in patient B. Patients karyotype showed chromosomal breaks with sister chromatid exchanges. Neither patient had abnormal alphafetoprotein and carcinoembryonic antigen serum levels. The rarity of such associations justifies the presentation of the cases.

Seventy-nine patients with advanced, measurable, metastatic colorectal cancer previously unexposed to chemotherapy were randomly assigned to treatment with either fluorouracil (FUra) administered intravenously at a dose of 370 mg/m2/d for 5 days or the combination of FUra in the same dose and schedule with high-dose continuous infusion leucovorin calcium (500 mg/m2/d) beginning 24 hours before the first dose of FUra and continuing for 12 hours after the completion of FUra therapy. Patients whose disease progressed on treatment with FUra alone were, if eligible, crossed over to receive leucovorin and FUra. Three patients on the FUra plus leucovorin arm of the study were excluded from the analysis because they did not meet eligibility requirements. The treatment arms were well balanced for prognostic criteria including performance status, age, prior radiotherapy, distribution of metastatic sites, and on-study carcinoembryonic antigen (CEA), lactic dehydrogenase, and serum albumin. FUra plus leucovorin was superior to FUra alone for response (P = .0019) and for time to progression or death (log-rank, P = .045). Response rates were 16 of 36 (44%) versus five of 40 (13%), and median time to progression or death was 164 versus 120 days in the two arms of the trial, respectively. Overall survival, however, while longer in the FUra and leucovorin arm was not significantly so. An analysis of the toxicities experienced by the patients in the two treatment groups showed that, except for significantly more stomatitis in the leucovorin arm of the study, the side effects experienced by patients treated with either regimen were comparable. These results suggest that the efficacy of FUra in patients with advanced, measurable, metastatic colorectal cancer can be enhanced significantly by administration of a continuous high-dose infusion of leucovorin calcium.

We present the case of a 72-year-old man with gastric tube cancer accompanied by multiple liver metastases, after esophagectomy for esophageal cancer, whose quality of life (QOL) was improved with a small dosage of TS-1. The patient's high serum AFP level suggested alpha-fetoprotein-producing gastric cancer. He was treated with half the standard dose of TS-1, because the patient's poor general condition necessitated chemotherapy with low toxicity and high efficacy. The daily dose was 40 mg for the first three courses and 50 mg for the last two. Each treatment course consisted of a four-week administration followed by two drug-free weeks. The patient received five courses of chemotherapy at our outpatient clinic before his death from re-progression of liver metastasis. No serious side effect except temporary stomatitis was observed. A decrease in tumor markers, alpha-fetoprotein and carcinoembryonic antigen, was obtained after 4 weeks. After 2 cycles, computed tomography and endoscopy examinations showed regression of the primary tumor and liver metastases, and tumor markers were decreased remarkably. The patient's QOL improved gradually after the treatment. His performance status before the chemotherapy was 3, and improved to 1 after two cycles. The small dosage of TS-1 was effective without any adverse effects, and improved the patient's QOL, for 6 months.

The objective of this study was to investigate the possible prognostic factors in patients with metastatic colorectal cancer (CRC) treated with protracted venous infusion (PVI) of 5-fluorouracil (5-FU). PVI of 5-FU is considered to be one of the standard therapies for patients with CRC because of its high efficacy and low toxicity, but possible prognostic factors in patients with CRC treated with PVI of 5-FU have not been reported until now. One hundred two consecutive patients with metastatic CRC, treated with PVI of 250 mg/m(2) /d of 5-FU at the National Cancer Center Hospital between January 1991 and December 1998, were investigated retrospectively. The data were evaluated for possible correlations with clinicopathologic indices or prognosis. In this study, grade III nausea, stomatitis, diarrhea, and hand-foot syndrome occurred in only 3%, 5%, 5%, and 6% of cases, respectively. No grade III or more hematologic toxicities were observed. The overall response (complete response + partial response) rate for all 102 cases was 26%, with a 95% CI of 18% to 35%. Overall median survival time for the 102 cases was 303 days. In multivariate analysis, the favorable prognostic factors were normal albumin level (<or=3.7 g/dl), histologic grades I, II, and low carcinoembryonic antigen level (<100 ng/ml).

To characterize the induction of antigen-specific immune response mediated by baculovirus, vectors expressing the E2 glycoprotein of hepatitis C virus or the carcinoembryonic antigen (CEA) under the control of the cytomegalovirus immediate-early promoter-enhancer were constructed. Additionally, a baculovirus vector encoding the E2 glycoprotein (Bac-G-E2) and expressing vesicular stomatitis virus glycoprotein (VSV-G) in the viral envelope was generated by inserting the VSV-G coding sequence downstream of the polyhedrin promoter. Mice were subjected to intramuscular, intranasal, or subcutaneous inoculations with Bac-E2 and the cellular immune response was monitored by ELISPOT and intracellular staining. Additionally, humoral response was monitored by titrating anti-E2 antibodies. Induction of a measurable anti-E2 T-cell response was observed only after intramuscular injection and was predominantly CD8(+) specific. The immunogenic properties of baculovirus as vaccine vector were not restricted to E2 because a CEA-specific CD4(+) T-cell response was observed upon intramuscular injection of Bac-CEA. Interestingly, the Bac-G-E2 vector was shown to be a more efficient immunogen than Bac-E2, in view of the 10-fold difference in the minimal dose required to elicit a measurable T-cell response upon intramuscular injection. Induction of inflammatory cytokines such as gamma interferon, tumor necrosis factor alpha, and interleukin-6 was detected as early as 6 h postinjection of Bac-G-E2. Most importantly, both vectors elicited CD8(+) T cells with effector function capable of lysing target cells loaded with a hepatitis C virus-specific epitope. Additionally, enhanced NK cytolytic activity was detected in immunized mice. Thus, these results further demonstrate that baculovirus may be considered a useful vector for gene therapy.
