Pharmacokinetics of indium-111-labeled B72.3 monoclonal antibody in colorectal cancer patients.

Mean time parameters provide a new approach to plasma pharmacokinetics of radiolabeled Mabs that may show important patient differences affecting diagnosis or treatment. We determined mean time pharmacokinetic parameters for 11 patients entered in a Phase I/II clinical trial for detection of colorectal cancer. Patients were administered 0.

Carotid artery resection and replacement in patients with head and neck malignant tumors.

Tumor involvement of the carotid artery with head and neck cancers may be present either simultaneously with the primary lesion or more often appears at a later date following resection of the primary tumor. Management of the secondary tumor consists of its resection together with the involved carotid artery with or without carotid artery reconstruction. The Authors are convinced that the best chance for cure of patients with advanced head and neck squamous cell cancers involving the carotid artery is radical extirpation with ablative surgery in the form of en block resection of the primary lesion, the secondary tumor, and the involved carotid artery followed by immediate revascularization.

Geriatric oncology: perspectives from decision analysis. A review.

The management of advanced cancer in the older person is variable. In some patients with common malignancies chemotherapy may palliate symptoms and prolong survival, while in other patients chemotherapy is a cause of overwhelming toxicity and supportive care is the preferred form of treatment. We explored the principles of individualized management for the older person with cancer and we used decision analysis as a guide.

Metastatic carcinoma of unknown primary: complete response to second-line treatment with plicamycin.

In selected groups of patients, metastatic carcinoma of unknown primary (MCUP) is highly responsive to cisplatin-based combination chemotherapy. These therapeutic responses usually are partial and shortlived. The authors report the case of a 41-year-old man whose MCUP relapsed after responding to cisplatin, bleomycin, and etoposide.

SPECT gallium scanning for lymphoma and infection.

Thirty gallium scans, using currently acceptable dosage levels (5-6 mCi) and a conventional rotating gamma camera, were performed on 20 patients with lymphoma or infection. Compared to planar scans, SPECT increased sensitivity and lesion detection from 48% to 89% in lymphoma, and from 50% to 80% in infection. The predictive value of a negative site was 81% in lymphoma and 67% in infection.
