BACKGROUND Protein antigens are presented to cytotoxic T lymphocytes as small peptides (approximately 9-10 amino acids long) bound to class I molecules of the major histocompatibility complex. The identification of tumor-associated antigens and specific peptide epitopes (i.e., antigenic determinants) may be useful in the development of anticancer vaccines.(More)
Prostate-specific Ag (PSA), which is expressed in a majority of prostate cancers, is a potential target for specific immunotherapy. Previous studies have shown that two 10-mer PSA peptides (designated PSA-1 and PSA-3) selected to conform to human HLA class I-A2 motifs can elicit CTL responses in vitro. A longer PSA peptide (30-mer) designated PSA-OP(More)
Antitumor immune response and chemotherapy-induced immunomodulation in colon cancer patients represented the rationale to design new strategies, like GOLFIG chemoimmunotherapy (gemcitabine, oxaliplatin, 5-fluorouracil/folinic acid, granulocyte macrophage colony-stimulating factor, and aldesleukine), that resulted a safe and very active regimen. Antitumor(More)
The aim of this pilot phase II trial was to investigate the toxicity and anti-tumour activity of a novel metronomic regimen of weekly cisplatin (CDDP) and oral etoposide (VP16) in high-risk patients with advanced NSCLC. The study enrolled 31 high-risk patients (27 men and 4 women aged 16-82 years; mean, 64.3) with NSCLC (18 stage IIIB and 13 stage IV) and(More)
Vaccine therapy is attractive for prostate cancer patients because the tumor is slow growing (allowing time to augment host responses) and occurs in an older population less likely to tolerate more toxic treatments. We have constructed an expression vector based on a monoclonal antibody (mAb) that targets the high affinity receptor for IgG (FcgammaRI, CD64)(More)
Previous results suggest that GEM affects 5-fluorouracil (5-FU) metabolism and pharmacokinetics in cancer patients, while combined with oxaliplatin, levo-folinic acid, and 5-FU (GOLF regimen), at doses achievable in cancer patients, determines high cytotoxic and proapoptotic antitumour activity in colon cancer cells in vitro. On these bases we designed a(More)
A number of recent clinical trials testing the combination of 5-fluorouracil (5-FU) and gemcitabine in patients with advanced pancreatic adenocarcinoma have shown a significant clinical response rate, but also significant toxicity. As the two antimetabolites may interact at several biochemical levels along their pathways of activation, we investigated(More)
Bevacizumab, is a humanized monoclonal antibody to vasculo-endothelial-growth-factor, with anticancer activity in non-small-cell-lung cancer (NSCLC) patients. Our previous results from a dose/finding phase I trial in NSCLC patients, demonstrated the anti-angiogenic effects and toxicity of a newest bevacizumab-based combination with fractioned cisplatin and(More)
PURPOSE Tumor cell killing by anticancer drugs may be supported by their immuno- and pharmacologic effects. Chemotherapy is in fact able to (A) upregulate tumor-associated antigen expression, including carcinoembryonic antigen (CEA) or other target molecules such as thymidylate synthase (TS); and (B) downregulate tumor cell resistance to the death signals(More)
PURPOSE An efficient adaptive immunity is critical for a longer survival in cancer. We investigated the prognostic value of tumor infiltration by CD8(+) T cells expressing the chemokine-receptor-7 (T(ccr7)) and the correlation between tumor infiltration by T(ccr7) and regulatory CD4(+)FoxP3(+) T cells (T(reg)) in 76 metastatic colorectal cancer (mCRC)(More)
