CD44 v3-containing isoforms are associated with HNSCC growth, migration, and matrix metalloproteinase activity and can be identified in lymph node metastasis.
CD44 expression was found in 92 of the 243 cases (37.9 %) and was associated with tumor size (P = 0.005) and lymph node metastasis (P = 0.023), respectively.
CD44 overexpression within the tumour core region and in lymph node metastases was identified as an independent prognostic factor for poor overall, disease-specific and disease-free survival in subsets of patients with advanced OSCC.
CD44 immunoexpression was a significant predictor of lymph node metastasis, while ALDH1<sup>high</sup> immunostaining was associated with angiolymphatic invasion.
CD44 Variant 6 Expression and Tumor Budding in the Medullary Invasion Front of Mandibular Gingival Squamous Cell Carcinoma Are Predictive Factors for Cervical Lymph Node Metastasis.
Abnormal expression of some CD44 molecules in tumor tissues can induce the degradation of the extracellular matrix, and is closely associated with axillary lymph node metastasis, angiogenesis, cancer progression, and drug resistance.
c-Fos promoted cell invasion and migration via CD44 pathway in OSCC. c-Fos could be used as a potential therapeutic target gene and an additional marker for evaluation of lymph node metastasis.
CD44s and CD44v6 were expressed in intraductal carcinoma of breast, the expression of CD44s and CD44v6 was significantly associated with lymph node metastases and invasion (P<0.01).
CD44st is a member of the CD44 family; abnormal expression of some CD44 isoforms are closely associated with axillary lymph node metastasis, cancer progression, and patients' prognosis.
Expression of CD44 and CD47 correlated with patient surgical stage, chemotherapy resistance and prognosis (all p<0.05), and expression of c-met correlated with chemotherapy resistance and prognosis (all p<0.05), but did not correlate with lymph node metastasis (all p>0.05).
Expression of CD44 variant exons 8-10 did not significantly correlate with histological type, depth of tumor invasion, lymphatic invasion, venous invasion, or lymph node metastasis.
Expression of CD44 splice variants containing epitopes encoded by exon v6 in primary tumors and pelvic lymph node metastases of cervical cancer patients is consistent with a prominent role of CD44 in the process of metastasis formation.
Expressions of CD44s and CD44v6 play an important role in tumor progression; especially, CD44v6 expression may be a useful predictor of lymph node metastasis, while the expressions of E-cadherin and beta-catenin complex are more probably related to tumor morphology than to tumor progression.
Immunohistochemical levels of matrix metalloproteinase-2 and CD44 variant 6 protein in the diagnosis and lateral cervical lymph node metastasis of papillary thyroid carcinoma.
In addition, PTCH and Gli1 expression was associated with lymph node metastasis (P=0.005 and P=0.001) and Grade II‑II tumors (P=0.020 and P=0.033) in breast cancer patients with the CD44+/CD24‑ phenotype.
Moreover, the breast cancer patients with homozygous unique SNP in CD44 intron 1 had breast cancer at earlier ages, larger tumor burden, more regional lymph node metastases at the time of diagnosis, and higher cancer recurrence rate.
Multivariate analysis demonstrated that CD44 expression and lymph node metastasis in gastric cancer and CD44 and sialyl Lea expression in colorectal cancer were significantly related to hepatic metastasis.
