Testicular choriocarcinoma is a non-seminomatous germ cell tumor (NSGCT) and is the rarest of all testicular cancers. Nearly all choriocarcinomas can be classified as either pure choriocarcinoma or as a component of a mixed germ cell tumor. Pure testicular choriocarcinoma is extremely aggressive and metastasizes early and extensively.

Eligible patients have squamous cell cancers of the head and neck with expected 5-year survival rates of < or =25%; a good performance status; adequate hematologic, hepatic, and renal functions; and no distant metastases. All patients receive 70 Gy megavoltage RT in 7 weeks (2 Gy/d x 5 d/wk).

Eligible patients have locally advanced (T4NXM0 or TXN2-3M0) non-small cell cancer ineligible for potentially curative surgical resection, a good performance status, adequate hematologic, hepatic, and renal functions, and no distant metastases. All patients receive a total tumor dose of 64.

Significant defects in responses to tetanus toxoid and influenza virus were observed in patients with advanced-stage breast cancer. To define whether these defects were associated with a defect in antigen presentation [dendritic cells (DCs)] or effector function (T cells), these cells were studied separately.

We found ineffective induction of antitumor CTL in mice bearing these tumors associated with measurable defects in the function of dendritic cells (DC) from these animals. In this study we investigate the mechanism of this defect in mature DC and find that functional DC can be generated by growth from the bone marrow of tumor-hearing animals.
