Chromosomal rearrangements in lymphocytes of head and neck squamous cell carcinoma treated with chemotherapeutic agents.

Squamous cell carcinoma especially of oral cavity is one of the most prevalent diseases in the world. Chromosomal rearrangements are known to play important role in the pathogenesis of many diseases including cancer. In case of Head and Neck Squamous Cell Carcinoma, chromosomal changes are detectable at all stages of tumor development providing excellent opportunity for chromosomal prognosis and therapy. The present work aimed to study the frequency and pattern of chromosomal aberrations in human peripheral blood lymphocyte culture of freshly diagnosed Head and Neck squamous cell carcinoma patients. Further In vitro anticancer drugs (5-Fluorouracil {5-FU } and Cisplatin) effects were studied for clastogenicity. Results indicated significant impact of chemotherapeutic agents on the frequency of different types of chromosomal rearrangements.
