Patient-specific vaccines derived from autologous tumor cell lines as active specific immunotherapy: results of exploratory phase I/II trials in patients with metastatic melanoma.

Seventy-four (74) patients with metastatic melanoma were treated with patient-specific vaccines derived from autologous tumor cell lines. Cryopreserved irradiated tumor cells were injected weekly for 3 weeks, then monthly for 5 months. At a median follow up >6 years, the median event-free survival (EFS) was 4.

High-dose chemotherapy and autologous stem cell rescue for metastatic breast cancer: superior survival for tandem compared with single transplants.

During 1990-1999, we treated 60 patients with breast cancer who had distant metastases with high-dose chemotherapy and autologous stem cell rescue (HDC) after they had responded to induction chemotherapy. HDC regimens were MiTepa (60 mg/m2 mitoxantrone by continuous intravenous infusion over 3 days plus 300 mg/m2 thiotepa intravenously over 2 hours daily x 3 days) and ICE (12 g/m2 ifosfamide, 1800 mg/m2 carboplatin, 2 g/m2 etoposide; all 3 by continuous intravenous over 4 days). At a median follow up >8 years, the median failure-free survival (FFS) was 13.

Intracavitary placement of autologous lymphokine-activated killer (LAK) cells after resection of recurrent glioblastoma.

This study was performed to obtain safety and survival data for patients with histologically confirmed recurrent glioblastoma multiforme (GBM) who received intralesional lymphokine-activated killer (LAK) cells following surgery. LAK cells were generated by incubating peripheral blood mononuclear cells with interleukin-2 for 3 to 5 days in vitro. Forty patients with pathologic confirmation of GBM at surgery had placement of autologous LAK cells into the tumor cavity.

Treatment of human solid malignancies with autologous activated lymphocytes and cimetidine: a phase II trial of the cancer biotherapy research group.

Objective: The Cancer Biotherapy Research Group conducted a clinical trial to verify encouraging reports of antitumor activity of autolymphocyte therapy.

Patients And Methods: Patients with a variety of advanced solid malignancies underwent an initial leukapheresis procedure to collect about 5 x 10(9) autologous lymphocytes that were stimulated in vitro for 3 days with anti-CD3 monoclonal antibody in the presence of indomethicin and cis-retinoic acid to obtain media that was frozen in aliquots. This media contained significant amounts of tumor necrosis factor (TNF)-alpha, interleukin (IL)-1beta, interferon-gamma, and IL6, but no IL-2.

Irradiated cells from autologous tumor cell lines as patient-specific vaccine therapy in 125 patients with metastatic cancer: induction of delayed-type hypersensitivity to autologous tumor is associated with improved survival.

Objective: We established short-term cultures of pure tumor cells for use as autologous tumor cell vaccines in an effort to study the effects of patients-specific immunotherapy.

Patients And Methods: Surgically resected fresh tumor was obtained from patients with metastatic cancer. Successful tumor cell lines (5 x 10(7)) were expanded to 10(8) cells, irradiated, and cryopreserved for clinical use.
