Effect of low doses of interleukin-2 injected perilymphatically and peritumorally in patients with advanced primary head and neck squamous cell carcinoma.
For 10 days, four patients with advanced squamous cell carcinoma of the head and neck received two daily injections of 100 units of natural IL-2, one around the tumor, the second near the tumor-draining lymph nodes. No side effects were observed. Histologic and ultrastructural examination of tumor and lymph nodes recovered at surgery showed that in many instances neoplastic cells were intermingled with numerous lymphocytes and eosinophils. Lymph nodes displayed hyperplasia of both cortical and paracortical areas and epithelioid venules infiltrated by lymphocytes and granulocytes. In a few cases, a decrease or disappearance of neoplastic lesions was also documented both clinically and histologically.
