abstract = {Mucosal melanomas of the head and neck (MMHN) are
aggressive tumors with poor prognosis, different opposed to
cutaneous melanoma. In this study, we characterized primary
mucosal malignant melanoma for the expression of
Kallikrein-related peptidase 6 (KLK6), a member of the KLK
family with relevance to the malignant phenotype in various
cancer types including cutaneous melanoma. Paraffin-embedded
MMHN of 22 patients were stained immunohistochemically for
KLK6 and results were correlated with clinical and
pathological data. In $77.3\%$ (17/22) of MMHN cases,
positive KLK6 staining was found. Staining pattern for tumor
cells showed a predominant cytoplasmic staining. However, in
six cases we also observed a prominent nuclear staining.
MMHN with a high KLK6 expression showed significantly better
outcome concerning local recurrence-free survival
(p = 0.013) and nuclear KLK6 staining was significantly
associated with the survival status (p = 0.027).
Overexpression of KLK6 was detected in more than $70\%$ of
MMHN and approximately $40\%$ of tumors showed a strong
expression pattern. Correlation between clinical outcome of
MMHN patients and overexpression of KLK6 has not been
addressed so far. Our data demonstrate for the first time
increased levels of KLK6 in MMHN and strengthen the
hypothesis that there might be a context-specific regulation
and function of KLK6 in mucosal melanoma.},
