Disease Characteristics:
- Patients with documented histologic and cytologic diagnosis of colon or rectal malignancy
- Patients with documented status post surgical resection of primary cancer or metastases
- Limited residual disease (i.e., CEA serum levels < 15 ng/mL and negative baseline CT scans, or no lesion > 1 cm)
Prior/Concurrent Therapy:
- Patients must have completed chemotherapeutic agents, biologic therapy, radiotherapy, other investigational therapy for cancer, or surgical procedures at least six weeks prior to study entry.
- Patients must have recuperated from surgery and toxicities (as a result of previous therapy) sufficiently prior to study entry
- Biologic Therapy: Patients who have received a murine, chimeric, CDR-grafted (humanized), or human IgG will be eligible provided pre-study evaluations demonstrate no significant reactivity with hMN-14 IgG (i.e., HAHA)
- Radiotherapy: No prior external beam irradiation to a field that includes more than 30% of the red marrow. No prior radiation to maximal tolerable levels for any critical organs (e.g., 3000 cGy for the liver; 2000 cGy for the lungs and kidneys)
Patient Characteristics/Inclusion Criteria:
- Performance Status: Patients with Karnofsky performance status > 70%
- Hematopoietic: ANC >/= 1.5 x 10/L; Hemoglobin >/= 10 g/dL; Platelets >/= 100 x 10/L
- Renal: Serum Creatinine </= 1.5 x ULN
- Hepatic: Serum Bilirubin </= 1.5 ULN; AST and ALT </= 2.5 x ULN; Alk Phosphatase </= 2.5 x ULN
- Cardiovascular: Patients with LVEF >/= 50% by required MUGA/2D-ECHO tests
- Pulmonary: Patients with DF and FEV1 >/= 60% by required Pulmonary Function Tests
- Central Nervous System: Patients with known metastatic disease to the CNS are excluded.
- Other: Patients agreeing to use a medically effective method of contraception during and for a period of three months after the treatment period. A pregnancy test will be preformed on each premenopausal female of childbearing potential immediately prior to entry into study. Patients must understand and give written informed consent.
