ABSTRACT

BACKGROUND AND OBJECTIVES: The aim of this study was to study the incidence, localization, and nature of second primary tumors arising in patients with primary laryngeal carcinoma and their correlation with the site, staging, and grade of differentiation. METHODS: Between 1979 and 1996, 877 patients underwent laryngeal surgery (850 male and 27 female; age range = 30.5-76 years). The second primary tumor was multicentric in 7 cases (14%), systemic in 16 cases (33. 3%), and "coincidental" in 25 cases (52%). In 3 cases the tumors were simultaneous, in 7 cases they were synchronous, and in 38 cases they were metachronous. In the 48 patients with multiple primary malignant neoplasm, the index tumor was glottic in 38 cases and supraglottic in the remaining 10, but the incidence of second tumors in these two groups was virtually matching, respectively: 38/709 (5. 3%) and 10/168 (5.9%). RESULTS: This study did not identify any correlation between the second primary tumor and the extension of the first neoplasm (T) and the presence of laterocervical lymph node metastases (N). Our data showed a higher incidence of second tumor in patients having G1 carcinomas compared with the other series with G2 and G3 carcinomas. As far as survival rates are concerned, a significant reduction was observed in patients developing a second primary tumor, regardless of whether the index tumor was glottic or supraglottic. CONCLUSIONS: The incidence of new tumors in patients with laryngeal carcinoma is not linked to the site, size, staging, or grade of differentiation of the index tumor.

ABSTRACT

The association between the expression of HLA-DR antigens on cervical epithelium and the local immune state of activation in colposcopically obtained biopsy specimens from patients with histologically documented wart virus infection was investigated. In normal cervical epithelium no HLA-DR staining was detected. No or few IL-2R positive cells were found in the contiguous sections. HLA-DR was expressed by epithelial cells in six out of the 14 samples of wart virus infection. The pattern of fluorescence was focal, but strong and diffuse, to the whole epithelial layer. In the six samples with HLA-DR positive epithelium the numbers of IL-2R positive cells in the lamina propria were strongly increased, ranging between 75 and 90%. HLA-DR expression by cervical epithelium was observed in only two of 12 samples from patients with mixed epithelial non-virus related abnormalities. No increase in the numbers of IL-2R positive cells was observed in this group of patients. Additionally, no significant differences in terms of T lymphocyte infiltrate were found among the three groups. The results indicate that wart virus infection is associated with enhanced HLA-DR epithelial expression and they lend support to the concept that in the human cervix the epithelium actively participates in the local immune response.
