This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. Objectives: 1)To determine the impact of the varying does and schedules of doctetaxel on CEA-specific T cell immune responses using the ELISPOT assay 2) To determin the recommended dose and schedule for further study as defined by the best immune response with acceptable toxicity 3) To document any objective antitumor response that occurs 4) To determine the impact of treatment on the quantity of circulating CEA cells using quantative real time PCR as an intermediate endpoint Medical Relevance: Patients with advanced metastatic CEA-bearing cancers of the colon or lung have very limited treatment options and those available have not been proven to improve overall survival. This is a population for which new therapies are needed. Cancer immunotherapy and target therapy has made significant advances in the last few years but when given alone they may succeed in stabilization of disease but have limited potential for causing major responses in patients with heavy tumor burden. Exploration of the combination of immunotherapy with chemotherapy is a logical next step to take in furthering the development of new treatment options for this group of patients. Expected Outcome: The endpoints of this trial are: 1) Tumor response measured according to standard RECIST criteria 2) Imune response will be measured by ELISPOT 3) The number of patients experiencing and toxicities will be recorded and the toxicity rate will be determined. 4) The number of circulating cancer cells will be determined by RT-PCR. It is expected that this trial will identify the best combination of terms of disease response, immune response, and toxicity to bring forward into a large Phase II trial.

该子项目是利用NIH/NCRR资助的中心赠款提供的资源的许多研究子项目之一。子项目和研究者（PI）可能从另一个NIH来源获得主要资金，因此可以在其他CRISP条目中表示。所列机构为中心，不一定是研究者所在机构。目的：1）使用ELISPOT测定确定不同剂量和时间表的多西他赛对CEA特异性T细胞免疫应答的影响2）确定推荐剂量和时间表用于进一步研究，如具有可接受毒性的最佳免疫应答所定义的3）记录发生的任何客观抗肿瘤应答4）使用定量真实的时间PCR作为中间终点，确定治疗对循环CEA细胞数量的影响医学相关性：晚期转移性CEA结肠癌或肺癌患者的治疗选择非常有限，并且现有的治疗方案尚未被证明可以改善总生存期。这是一个需要新疗法的人群。 癌症免疫治疗和靶向治疗在过去几年中取得了重大进展，但单独使用时，它们可能成功稳定疾病，但在肿瘤负荷重的患者中引起重大反应的潜力有限。探索免疫疗法与化疗的结合是进一步为这组患者开发新治疗方案的合理下一步。预期结果：本试验的终点为：1）根据标准RECIST标准测量肿瘤缓解; 2）通过ELISPOT测量免疫缓解; 3）记录发生毒性的患者数量，并确定毒性发生率。4)将通过RT-PCR测定循环癌细胞的数量。预计该试验将确定疾病反应、免疫反应和毒性的最佳组合，以进入大型II期试验。
