Immunohistochemical evaluation of type IV collagen and laminin-332 γ2 chain expression in well-differentiated oral squamous cell carcinoma and oral verrucous carcinoma: a new recommended cut-off

Abstract: Isolated immunohistochemical study of type IV collagen does not clearly define that a lesion is invasive or non-invasive and evaluation of Ln-332 γ2 chain expression (cut-off 5%) may be useful as a marker for description of biological differences and diagnosis of OVC from well-differentiated OSCC, especially in doubtful cases.

“…Verrucous carcinoma which also called Ackerman tumor, Buschke-Lowenstein tumor, florid oral papillomatosis, epithelioma cuniculatum, or snuff dipper's cancer is a nonmetastasizing low grade variant of oral squamous cell carcinoma [68, 73]. The incidence rate has been estimated as one lesion per 1.000.000 of the population each year.…”

“…However, 15% to 51% of the lesions have been found in people without these habits [10, 68]. The most common affected sites in the oral cavity are vestibular mucosa, buccal mucosa, gingivae, and the tongue [10, 68, 73]. There is a male predilection with the majority of lesions being reported in the sixth decade [4, 68, 73].…”

“…O padrão de marcação da laminina-332 frequentemente encontrado em tecidos normais ou hiperplasia, quando usado como controle, foi restrito à MB ou negativo, 13,14,17,22,24 evidenciando que em situações de normalidade ou benignidade a MB está inalterada.…”

“…18,20 A intensidade da marcação também foi analisada em mucosa normal, displasia e carcinoma e foi demonstrado que quanto maior a alteração tecidual, mais acentuada foi a marcação. 21,24 Trabalhos mostraram ainda que houve pior prognóstico de sobrevida para pacientes que tiveram mais células marcadas para laminina-332 em epitélio invasivo, 13,19 embora não tenha havido relação com o estadiamento do tumor.…”
