Objective: To determine the levels of serum sCD44v6 in patients with oral cancer and evaluate the value of serum sCD44v6 in adjuvant diagnosis, staging and monitoring treatment response in these patients.
Materials And Methods: A total of 112 hospitalized patients with oral and maxillofacial malignancy and 28 healthy individuals were examined for serum sCD44v6 levels. Venous blood was collected from these patients and the healthy individuals. One week after treatment, venous blood was collected once again in 60 patients with oral and maxillofacial squamous cell carcinoma (OSCC).
Results: The sCD44v6 concentration was not significantly different between patients with oral and maxillofacial malignancy and control group (P > 0.05). The levels of serum sCD44v6 in patients with OSCC and salivary carcinoma showed no difference with those in control group (P > 0.05). The sCD44v6 level in patients with stage III and IV disease was higher than that of patients with stage I and II and that of the control group, but the difference was not significant (P > 0.05). Serum sCD44v6 levels in patients with OSCC after treatment became lower than that prevailed during pretreatment (P < 0.05).
Conclusion: The possible roles of CD44v6 in the diagnosis of oral and maxillofacial malignancy deserve further elucidation and evaluation. Serum sCD44v6 may be a valuable marker in monitoring treatment response in patients with OSCC.

Aim: CD44v6 is an isoform of CD44 that can be present in soluble form (sCD44v6). The aim of this study is to evaluate the presence of soluble CD44 (sCD44) and sCD44v6 in serum of children with B-cell precursor acute lymphoblastic leukemia (B-ALL) and their relationship with prognosis.
Methods: sCD44v6 and sCD44 levels were measured in the sera of patients and healthy children by enzyme-linked immunosorbent assay.

Objective: To investigate the serum levels of sCD44v6 and sE-cadherin (sE-cad) in patients with esophageal squamous cell carcinoma.
Methods: The serum samples were collected from 65 cases of esophageal squamous cell carcinoma, 32 cases of erosive esophagitis and 35 healthy subjects. Serum sCD44v6 and sE-cad levels were measured by enzyme linked immunosorbent assay (ELISA).

Purpose: To evaluate differences in the serum concentrations of cell adhesion molecules (CAMs) after retroperitoneal laparoscopic and conventional open radical nephrectomies for localized renal-cell carcinoma (RCC).
Patients And Methods: A total of 62 patients with stage T(1)N(0)M(0) RCC were randomized to either a retroperitoneal laparoscopic radical nephrectomy group (n=31) or an open group (n=31). Serum levels of soluble cluster of differentiation 44 splice variant 6 (sCD44v6), soluble intercellular adhesion molecule-1 (sICAM-1), soluble vascular cell adhesion molecule-1 (sVCAM-1), and soluble epithelial cadherin (sE-cadherin) were determined independently by enzyme linked immunosorbent assay (ELISA) preoperatively, and on postoperative days 1 and 5.

Purpose: CD44 is a cell surface glycoprotein involved in cell-cell and cell-substrate interactions, which may be shed or released into circulation by proteolytic enzymatic mechanisms. Alternative splicing of CD44 and aberrant levels of soluble CD44 variants in the serum of cancer patients have been correlated to tumor progression and metastasis in different tumors including breast cancer. In this study we evaluated the clinical value of CD44 serum levels (sCD44) in patients with primary breast cancer.
