Tumor differentiation and tumor-host interactions as prognostic determinants in squamous cell carcinoma of the lip.
|
| Abstract |
A series of 70 patients with the squamous cell carcinoma of the lip and followed-up for at least 5 years, was assessed on light microscopy and using histochemical staining for ANAE (acid-naphthyl acetate esterase) to demonstrate the morphological manifestations of tumor-host reactivity. The factors analysed include cancer differentiation (intrinsic malignancy) and stromal reactions (intensity of the immunocompetent cell infiltrate including the mast cells and the subpopulations, i.e. B- or T lymphocytes or mononuclear phagocytes). Differentiation of the lip cancer was shown to be directly (although not statistically significantly) related to the 5-year survival, as was also the intensity of the stromal immunocompetent cell infiltration. Cancer metastases were evidently the most powerful prognostic determinants, their development being influenced both by the intensity of the stromal immunocompetent cell infiltrate and cancer differentiation. B lymphocytes far outnumbered the T and MPS cells in all the infiltrates studied, the percentages of the latter two cell types, however, being inversely related to the intensity of the infiltrate. The cell composition in the infiltrates was seemingly without effect on the frequency of metastases and the 5-year survival, as was the stromal mast cell reaction, too. It was concluded that analysis of tumor-host relationships using a variety of morphological and immunohistochemical techniques may be of benefit in predicting the clinical course of lip cancer.
