At the annual meeting of the American Academy of Otolaryngology–Head and Neck Surgery, San Diego, Calif, September 1990, David E. Eibling et al, San Antonio, Tex, presented their work with tumor-infiltrating lymphocytes in locally advanced squamous cell carcinoma of the head and neck.
Twenty-two patients with advanced squamous cell carcinoma of the head and neck were studied for a minimum of 30 months. Correlation between in situ characteristics of tumor-infiltrating lymphocytes and recurrent disease was investigated. At the time of surgery, tumor specimens were collected, snap frozen, and stained with immunoperoxidase. Monoclonal antibodies were used for identification and classification. A variety of head and neck sites were included in the study. Lymphocytes with the CD4+ marker were predominant in the parenchyma of tumors.
Twelve patients (55% ) developed recurrent disease from 4 to 18 months after therapy. There was a significant difference in recurrence rates between patients having greater than 20
