Previous experience using 131I anti-CEA antibody, which irradiates at a variable low dose rate in combination with a multimodality treatment program, has demonstrated acceptable toxicity and response in primary intrahepatic cholangiocarcinoma. In attempting to improve therapy, Cis-platin was added to the prior regimen. Induction therapy was unchanged.

A previously reported Phase I/II multimodality program for non-resectable hepatocellular cancer began with external beam-radiation and chemotherapy, followed by administration of 131I antiferritin-specific radioimmunoglobulin and led to a 48% remission (7% complete remission and 41% partial remission). Survival and response depended on alpha fetoprotein status. AFP+ patients had a median survival of 5 months; AFP- patients had a median survival of 10.

The Radiation Therapy Oncology Group (RTOG) conducted a Phase I/II study in hepatocellular cancer that closed on September 9, 1987 and some results presented previously. Here, 17 patient characteristics are evaluated to identify any of prognostic significance. Two hundred sixteen patients were entered and 198 (74% with metastases and/or previous chemotherapy) were evaluable.

In addition, physiological factors that limit antibody uptake, varied routes of administration, toxicity of treatment, as well as present clinical progress are reviewed.

This rapid cell division suggested that hyperfractionated radiation and chemotherapy might add an advantage in gaining remission of this malignancy. One hundred and thirty-five patients (70% with metastasis and/or previous treatment) were prospectively treated with single daily fractions to the liver (3.

Radioimmunoglobulin therapy is a new treatment modality that is easily administered, well tolerated, and can be given on an outpatient basis. It is not, however, as simplistic an approach to cancer therapy as commonly thought. It incorporates the sciences of immunology, physiology, radiobiology, chemistry, and physics, as well as oncology, all of which must be understood if radioimmunoglobulin therapy is to reach its potential.

Within this group of 18 patients, there were 34 cranial nerve abnormalities and four Horner's syndromes. Overall, 62% of cranial nerve deficits recovered completely (CR) and 32% recovered partially (PR), for a total response rate of 94% to definitive radiotherapy.

Therapy began in all trials with external beam irradiation and chemotherapy. The dosimetric results with 131I antiferritin indicated that 30 mCi (8 to 10 mCi/mg immunoglobulin G [IgG]) was sufficient to saturate the tumor.

Less than 0.25 per cent of all laryngeal carcinomas are adenoid cystic, and only 15 such cases of supraglottic origin are recorded in the literature.
