Tumor antigen-derived peptides have been widely used to elicit tumor-specific cytotoxic T lymphocytes (CTLs). MAGE gene products are of particular interest owing to their wide expression in many tumors and their potential to induce tumor-specific CTL responses. Antigen-specific CTLs induced by MAGE gene-derived peptides have proven to be highly efficacious in the prevention and treatment of var...
A cell-mediated cytotoxicity test, quantitated by postlabeling with tritiated thymidine, was used to asses immune reactivity of cancer patients to the HeW cell line derived from serous cystadenocarcinoma of the ovary. Lymphocytes from 71.4% of serous and mucinous cystadenocarcinoma patients demonstrated a cytotoxic response towards the HeW cells, whereas no reactivity was observed towards targe...
PURPOSE Exposing human tumor cells to sublethal doses of external beam radiation up-regulates expression of tumor antigen and accessory molecules, rendering tumor cells more susceptible to killing by antigen-specific CTLs. This study explored the possibility that exposure to palliative doses of a radiopharmaceutical agent could alter the phenotype of tumor cells to render them more susceptible ...
objective(s):tumor-associated antigen (taa) subunit-based vaccines constitute promising tools for anticancer immunotherapy. however, a major limitation in the development of such vaccines is the poor immunogenicity of peptides when used alone.the aim of this study was to develop an efficient vaccine delivery system and adjuvant to enhance anti-tumor activity of a synthetic her2/neu derived pept...
OBJECTIVES The purpose of the study was to identify predictive factors of tumor response to preoperative chemoradiotherapy for rectal adenocarcinoma. METHODS Ninety-eight patients with nonmetastatic rectal adenocarcinoma received preoperative concurrent chemoradiotherapy and underwent mesorectal excision. After treatment, tumor response according to tumor regression grade were evaluated. The ...
OBJECTIVE To investigate the possibility of objective clinical assessment of the radioresponse of cervical cancer via determination of serum squamous cell carcinoma antigen levels and magnetic resonance imaging (MRI)-based estimation of tumor shrinkage. METHODS The cases of 60 patients undergoing definitive radiotherapy for cervical squamous cell carcinoma (stage I-II: n = 20; stage III-IV: n...
