RATIONALE: Vaccines made from a person's tumor cells and white blood cells may make the body build an effective immune response to kill tumor cells.
PURPOSE: This phase I trial is studying the side effects and best dose of vaccine therapy in treating patients who are undergoing surgery for stage IB, stage II, or stage IIIA non-small cell lung cancer.
- Determine the maximum tolerated dose of adjuvant autologous dendritic cells loaded with irradiated autologous tumor cells in patients with stage IB-IIIA non-small cell lung cancer undergoing resection.
- Determine the safety and tolerability of this vaccine in these patients.
- Determine the feasibility of this vaccine in these patients.
- Determine vaccine-specific and antitumor immunity in patients treated with this vaccine.
OUTLINE: This is a dose-escalation study.
Patients undergo leukaphersis to isolate peripheral blood mononuclear cells (PBMC). PBMC are expanded ex vivo to generate monocyte-derived dendritic cells (DC). Autologous tumor cells are harvested and purified at the time of surgical resection. DC are then loaded with irradiated autologous tumor cells.
Within 4-8 weeks after surgical resection, patients receive autologous DC loaded with irradiated autologous tumor cells intradermally on approximately days 1, 30, and 60 in the absence of unacceptable toxicity.
Cohorts of 6-9 patients receive escalating doses of vaccine until the maximum tolerated dose (MTD) is determined. If 2 of 9 patients in the first cohort experience dose-limiting toxicity, that dose level is considered the MTD.
Patients are followed at approximately 1 and 4 months, and then every 6 months for 4 years.
PROJECTED ACCRUAL: A total of 12-15 patients will be accrued for this study within 18 months.
Primary Purpose: Treatment
autologous tumor cell vaccine, therapeutic autologous dendritic cells, adjuvant therapy, biological therapy, conventional surgery, surgery, tumor cell derivative vaccine, vaccine therapy

Graft-versus-tumor (GVT) effects have been thought to mostly result from allogeneic transplants; however, there is a growing body of research that supports a possible autologous GVT effect. In early c...

Methods of implanting a CELL NUCLEUS from a donor cell into an enucleated acceptor cell. Often the nucleus of a somatic cell is transferred into a recipient OVUM or stem cell (STEM CELLS) with the nucleus removed. This technology may provide means to generate autologous diploid pluripotent cell for therapeutic cloning, and a model for studying NUCLEAR REPROGRAMMING in embryonic stem cells. Nuclear transfer was first accomplished with frog eggs (RANA PIPIENS) and reported in 1952.
Lymphocytes that show specificity for autologous tumor cells. Ex vivo isolation and culturing of TIL with interleukin-2, followed by reinfusion into the patient, is one form of adoptive immunotherapy of cancer.
A cell-separation technique where magnetizable microspheres or beads are first coated with monoclonal antibody, allowed to search and bind to target cells, and are then selectively removed when passed through a magnetic field. Among other applications, the technique is commonly used to remove tumor cells from the marrow (BONE MARROW PURGING) of patients who are to undergo autologous bone marrow transplantation.
Non-hematopoietic cells, with extensive dendritic processes, found in the primary and secondary follicles of lymphoid tissue (the B cell zones). They are different from conventional DENDRITIC CELLS associated with T-CELLS. They are derived from MESENCHYMAL STEM CELLS and are negative for class II MHC antigen and do not process or present antigen like the conventional dendritic cells do. Instead, follicular dendritic cells have FC RECEPTORS and C3B RECEPTORS that hold antigen in the form of ANTIGEN-ANTIBODY COMPLEXES on their surfaces for long periods for recognition by B-CELLS.
Recirculating, dendritic, antigen-presenting cells containing characteristic racket-shaped granules (Birbeck granules). They are found principally in the stratum spinosum of the EPIDERMIS and are rich in Class II MAJOR HISTOCOMPATIBILITY COMPLEX molecules. Langerhans cells were the first dendritic cell to be described and have been a model of study for other dendritic cells (DCs), especially other migrating DCs such as dermal DCs and INTERSTITIAL DENDRITIC CELLS.
Blood is a specialized bodily fluid that delivers necessary substances to the body's cells (in animals) – such as nutrients and oxygen – and transports waste products away from those same cells. In vertebrates, it is composed of blo...
