We proceeded with intratumoral injection therapy of dendritic cells (DC) in combination with hyperthermia for 41 cancer patients in the past two years. We confirmed a total of two CR cases (one of them already reported). We report two successful cases in this paper. Case 1: A uterine cervical cancer patient with metastases in cervical and abdominal lymphnodes was treated with intratumoral DC injection therapy combined with hyperthermia in cervical. She showed a CR not only in cervical but also in abdominal lymph nodes. Case 2: A sialyl grand cancer patient with metastases in cervical and axillary lymphnodes was treated with intratumoral DC injection therapy combined with hyperthermia in cervical. She showed a PR. 相似文献

Marinobacter comprises Gram‐negative, aerobic, motile, and rod‐shaped bacteria within the γ‐subclass of the Proteobacteria and is known to be halophilic or halotolerant, heterotrophic neutrophile. Two strains classified as belonging to Marinobacter, named PAD‐2 and SeT‐1, were isolated from marine sediment. The most closely related species of PAD‐2 and SeT‐1 are M. alkaliphilus and M. guinea, respectively. The strain PAD‐2 exhibited remarkably higher denitrification at concentrations of 0.5 to 1 M NaCl (3–6% w/w) than at other salinities (2 and 3 M NaCl, 12–18% w/w), and optimal denitrification was observed in media with 0.5 M NaCl. The effect of pH on denitrification by strain PAD‐2 was also examined, and the optimum denitrification occurred at neutral pH rather than under alkaline conditions. Overall, strain PAD‐2 appears to be a novel halotolerant species belonging to the genus Marinobacter that shares many characteristics, such as substrate utilization profile and optimum NaCl concentration for growth with M. alkaliphilus.

A 82-year-old man was admitted into our hospital complaining of dysphagia. Endoscopic examination revealed an elevated tumor in the middle esophagus, and biopsy revealed carcinosarcoma. He underwent chemo-radiotherapy, and the size of tumor decreased remarkably and almost disappeared 7 months later. However, a metastatic lesion appeared 11 months later, and eventually he died. Autopsy revealed a sarcomatous element in the metastatic part, but the primary lesion showed no recurrence. We report herein this rare case of carcinosarcoma of the esophagus that was treated with chemo-radiotherapy. 相似文献

Tissue factor (TF), the trigger protein of the extrinsic blood coagulation cascade, is abundantly expressed in various cancers including gastric cancer. Anti-TF monoclonal antibodies (mAbs) capable of targeting cancers have been successfully applied to armed antibodies such as antibody-drug conjugates (ADCs) and molecular imaging probes. We prepared an anti-TF mAb, clone 1084, labeled with astatine-211 (211At), as a promising alpha emitter for cancer treatment. Alpha particles are characterized by high linear energy transfer and a range of 50-100 µm in tissue. Therefore, selective and efficient tumor accumulation of alpha emitters results in potent antitumor activities against cancer cells with minor effects on normal cells adjacent to the tumor. Although the 211At-conjugated clone 1084 (211At-anti-TF mAb) was disrupted by an 211At-induced radiochemical reaction, we demonstrated that astatinated anti-TF mAbs eluted in 0.6% or 1.2% sodium ascorbate (SA) solution were protected from antibody denaturation, which contributed to the maintenance of cellular binding activities and cytocidal effects of this immunoconjugate. Although body weight loss was observed in mice administered a 1.2% SA solution, the loss was transient and the radioprotectant seemed to be tolerable in vivo. In a high TF–expressing gastric cancer xenograft model, 211At-anti-TF mAb in 1.2% SA exerted a significantly greater antitumor effect than nonprotected 211At-anti-TF mAb. Moreover, the antitumor activities of the protected immunoconjugate in gastric cancer xenograft models were dependent on the level of TF in cancer cells. These findings suggest the clinical availability of the radioprotectant and applicability of clone 1084 to 211At-radioimmunotherapy. 相似文献

A 16-year-old boy was diagnosed as having primary sclerosing cholangitis (PSC), based on retrograde cholangiography showing mixed features of narrowing and dilatation of the common hepatic and intrahepatic bile ducts. However, periductal fibrosis was not observed in the needle biopsy liver specimen. The liver biopsy specimen obtained 11 years previously, at the onset of the disease had disclosed a marked infiltration of eosinophils in the portal tract with eosinophilic catinonic protein immunostaining, with marked eosinophilia (54%) being noted. In Japanese reports, eosinophilia of more than 7% was reported in 13 of 32 (40.6%) PSC patients. However, the early stage of PSC, with marked eosinophilia and eosinophilic infiltration in the liver, such as in the present case, has rarely been reported. The findings in this case suggest that eosinocytes are related to the pathogenesis of PSC. 相似文献

Background
X-ray cross-complementing group 1 (XRCC1) polymorphisms affect DNA repair capacity and may therefore be of importance in colorectal carcinogenesis. Alcohol consumption, an important risk factor for colorectal cancer, may induce carcinogenesis through DNA damage caused by the toxic effects of alcohol or its metabolites. Therefore, we examined the associations of XRCC1 Arg399Gln, Arg280His, and Arg194Trp polymorphisms with colorectal cancer and the impact of the association between alcohol consumption and colorectal cancer risk.Methods
This case-control study in Fukuoka, Japan including 685 cases and 778 controls. The cases were incident patients with histologically confirmed colorectal adenocarcinoma. The controls were randomly selected community subjects.Results
The XRCC1 399Gln/Gln genotype was significantly associated with colorectal cancer risk (adjusted odds ratio [OR] 1.57, 95% CI 1.01–2.42; relative to 399Arg/Arg genotype). The association was strongest in individuals with high alcohol consumption. The Arg280His polymorphism modified the association between alcohol consumption and colorectal cancer risk (interaction P = 0.049). The OR of colorectal cancer in individuals with the 280His allele was 0.45 (95% CI 0.26–0.78) as compared with the 280Arg/Arg genotype limited to the 399Gln allele (interaction P = 0.001). The adjusted ORs for 399Gln/Gln-280Arg/Arg-194Arg/Arg and 399Arg/Gln-280Arg/Arg-194Arg/Trp were 1.71 (95% CI 1.02–2.87) and 1.57 (95% CI 1.05–2.33), respectively, with 399Arg/Arg-280Arg/Arg-194Arg/Arg as reference (interaction P = 0.418).Conclusions
The findings are additional evidence that individuals with the XRCC1 399Gln/Gln genotype have an increased risk of colorectal cancer, and that XRCC1 polymorphisms have an important role in colorectal cancer risk associated with alcohol consumption or gene-gene interaction.Key words: XRCC1 polymorphisms, alcohol consumption, colorectal cancer 相似文献100.
