抄録 To determine the feasibility, safety, humoral immune response, and biological activity of multiple intratumoral injections of Ad5CMV-p53, and to characterize the pharmacokinetics of Ad5CMV-p53 in patients with advanced non-small cell lung cancer (NSCLC). Fifteen patients with histologically confirmed NSCLC and p53 mutations were enrolled into this phase I trial. Nine patients received escalating dose levels of Ad5CMV-p53 (1 × 109 to 1 × 1011 plaque-forming units[PFU]) as monotherapy once every 4 weeks. Six patients were treated on a 28-day schedule with Ad5CMV-p53 in combination with intravenous administration of cisplatin (80 mg/m2). Patients were monitored for toxicity, vector distribution, antibody formation, and tumor response. Fifteen patients received a total of 63 intratumoral injections of Ad5CMV-p53 without dose-limiting toxicity. The most common treatment-related toxicity was a transient fever. Specific p53 transgene expression was detected using reverse-transcriptase polymerase chain reaction in biopsied tumor tissues throughout the period of treatment despite of the presence of neutralizing anti-adenovirus antibody. Distribution studies revealed that the vector was detected in the gargle and plasma, but rarely in the urine. Thirteen of 15 patients were assessable for efficacy; one patient had a partial response (squamous cell carcinoma at the carina), 10 patients had stable disease, with three lasting ≥9 months, and 2 patients had progressive disease. Multiple courses of intratumoral Ad5CMV-p53 injection alone or in combination with intravenous administration of cisplatin were feasible and well tolerated in advanced NSCLC patients, and appeared to provide clinical benefit.

抄録 We encountered two cases of pulmonary embolism (PE)/venous thrombs (DVT) after surgery for esophageal cancer. The first case was a 58-year-old male. He underwent a subtotal esophagectomy and reconstruction using the stomach via the subcutaneus route. His postoperative course was stable; however, 13 days after the operation、 he had an elevated fever and pulmonary thrombi were observed on CT-scan screening. Scintigraphy confirmed the thrombi. An inferior vena cava filter (IVCF) was inserted and anti-coagulation therapy using heparin was started. His fever subsided, and 35 days after the operation, the thrombi disappeared. He was discharged thereafter and is being followed up using warfarin. The second case was a 74-year-old male. He also underwent subtotal esophagectomy and reconstruction using the stomach via the subcutaneus route. A central line was inserted via right femoral vein; however, the artery was injured and pressurization to the vessel was needed. His post-operative course was stable and symptom-free; however, ultrasound screening detected DVT in his right femoral vein. IVCF was mserted and anti-coagulation therapy was begun, thrombi disappeared 8 days after the therapy.

抄録 <p>A sustained release system for interleukin-2 (IL-2), and IL-2 mini-pellet (IL-2 mp), was developed by fusing IL-2 into a needle shaped collagen. Serum concentration of IL-2 after a single subcutaneous injection of the IL-2 mp into C57BL/6 mice remained elevated longer than after an injection of aqueous IL-2. IL-2 in the serum became undetectable by 6h after a subcutaneous injection of 1 x 10(6) unit of IL-2 in phosphate-buffered saline (PBS). In contrast, after a single subcutaneous injection of IL-2 mp containing the same amount of IL-2, the concentration of IL-2 increased to its maximum at 6h after injection, then began to decrease gradually. IL-2 was detected even on the third day after a single subcutaneous injection of one IL-2 mp. Augmentation of NK activity and generation of IL-2 activated killer cells were observed in the spleen from day 1--day 3 after a single subcutaneous injection of IL-2 mp into C57BL/6 mice. This activation was not observed following a single subcutaneous injection of the same amount of IL-2 in PBS. Adoptive immunotherapy by a single subcutaneous injection of IL-2 mp followed by intravenous injections of in vitro cultured IL-2 activated killer cells showed better results in decreasing the number of metastases of Lewis lung carcinoma in C57BL/6 mice than immunotherapy using IL-2 solution.(ABSTRACT TRUNCATED AT 250 WORDS)</p>

抄録 Replication-selective tumor-specific viruses constitute a novel approach for treatment of neoplastic disease. These vectors are designed to induce virus-mediated lysis of tumor cells after selective viral propagation within the tumor. Human telomerase is highly active in more than 85オ of primary cancers, regardless of their tissue origins, and its activity correlates closely with human telomerase reverse transcriptase (hTERT) expression. We constructed an attenuated adenovirus 5 vector (Telomelysin, OBP-301), in which the hTERT promoter element drives expression of E1 genes. Since only tumor cells that express telomerase activity would activate this promoter, the hTERT proximal promoter would allow for preferential expression of viral genes in tumor cells, leading to selective viral replication and oncolytic cell death. Lymphatic invasion is a major route for cancer cell dissemination, and adequate treatment of locoregional lymph nodes is required for curative treatment in patients with gastrointestinal tumors. We demonstrated that intratumoral injection of Telomelysin mediates effective in vivo purging of metastatic tumor cells from regional lymph nodes. Moreover, using noninvasive whole-body imaging, we found that intratumoral injection of Telomelysin followed by regional irradiation induces a substantial antitumor effect, resulting from tumor cell-specific radiosensitization, in an orthotopic human esophageal cancer xenograft model. These results illustrate the potential of oncolytic virotherapy as a promising strategy in the management of human gastrointestinal cancer.

抄録 Secreted frizzled-related protein 2, (SFRP2) is a Wnt inhibitor whose promoter CpGs were recently found to be methylated at high frequency in colorectal cancers (CRCs). We hypothesized that the pattern of SFRP2 methylation may differ throughout the promoter during progressive tumorigenesis. Using combined bisulfite restriction analysis (COBRA), two methylation-sensitive regions (Regions A and B) of the SFRP2 promoter were investigated in 569 specimens of colorectal tissue:222 CRCs, 103 adenomatous polyps (APs), 208 normal colonic mucosa from CRC patients (N-Cs), and 36 normal colonic mucosa from subjects with no evidence of colorectal neoplasia at colonoscopy (N-Ns). Extensive (including both Regions A and B) and partial (either Region A or B) SFRP2 methylation levels were found in 61.7% and 24.8% of CRCs, 8.7% and 37.9% of APs, 3.9% and 39.9% of N-Cs, and 0% and 30.6% of N-Ns, respectively. Extensive methylation of the SFRP2 promoter was present primarily in CRCs, while partial methylation was common in APs. Whereas APs with the KRAS mutant showed no correlation to any pattern of SFRP2 methylation, extensive methylation of the SFRP2 promoter was significantly associated with KRAS mutant CRCs (p<.0001), suggesting that genetic alteration in the RAS-RAF pathway might precede the spread of CpG methylation through the SFRP2 promoter, which is observed in over 60% of advanced colorectal tumors.
