Abstract
Objective
The current study aimed to investigate the characteristics of tumor-associated macrophages (TAMs) and their association with microvascular density (MVD) in tumor progression in different grades of orofacial squamous cell carcinoma (OSCC) in the Pakistani population.
Study Design
This prospective study included 234 patients with oral cancer reported at different hospitals in Pakistan diagnosed with OSCC. Tumors were graded on the Anneroth grading system and the association between the frequency of TAMs and MVD was examined in vivo. The macrophages visible through immunohistochemistry for CD68 and the microvessels observed through immunohistochemistry for CD34 were manually counted in 3 high-power fields.
Results
The CD68 and CD34 counts were significantly lower in well-differentiated squamous cell carcinoma compared to poorly differentiated squamous cell carcinoma. Linear regression analysis revealed a positive correlation between the area percentage of CD68 immunoreactivity and the grade of the tumor (r = 0.776). Vice versa, a positive correlation also existed between the area percentage of CD34 immunoreactivity and the grade of the tumor (r = 0.690). Pearson correlation revealed a positive association between the TAMs and MVD (r = 0.680; P < .001).
Conclusions
There was an increased population of tumor-associated macrophages and tumor angiogenesis with the increasing grade of orofacial squamous cell carcinoma. (Oral Surg Oral Med Oral Pathol Oral Radiol YEAR;VOL:page range)
期刊介绍:
Oral Surgery, Oral Medicine, Oral Pathology and Oral Radiology is required reading for anyone in the fields of oral surgery, oral medicine, oral pathology, oral radiology or advanced general practice dentistry. It is the only major dental journal that provides a practical and complete overview of the medical and surgical techniques of dental practice in four areas. Topics covered include such current issues as dental implants, treatment of HIV-infected patients, and evaluation and treatment of TMJ disorders. The official publication for nine societies, the Journal is recommended for initial purchase in the Brandon Hill study, Selected List of Books and Journals for the Small Medical Library.
