Abstract:
The tumor suppressor gene p16, when altered, has been shown to play a role in oncogenesis in many different tumor types including head and neck cancer. The goal of this study was to analyse alterations to p16 in squamous cell carcinoma (SCC) of the head and neck and to correlate these with clinical outcome. RNA was isolated from 26 SCC head and neck tumors and from 24 matched controls. A reverse transcription polymerase chain reaction was utilized to generate p16 cDNA, which was sequenced and analysed for alterations. In the 26 patient group 58% of the tumors had a p16 alteration, which were characterized by: 8 deletions, 1 insertion/deletion, 4 point mutations and 2 with no p16 expression. In 24 matched normal tissue samples there were no p16 alterations. Those patients with p16 alterations appear to have survival rates comparable to those without p16 alterations, although patients with p16 alterations appear to have more recurrences.

Cancers Originate from Somatic Mutations in a Single Cell
Tumor Progression
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...

The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...
