Abstract:
The aim of the present study was to analyze different prognostic factors to calculate the overall survival in oral squamous cell carcinoma (OSCC). Samples retrospectively collected from 99 patients with primary OSCC were analyzed with regard to tumor node metastasis stage, grading, and 5-year survival time and summarized at an SPSS 11.0 databank. Treated were 72 men and 27 women (average age 59 years) due to oral squamous cell carcinoma. A general 5-year survival time of 57.3% was found. Patient survival depended on tumor size and the extent of lymph node metastasis: survival was 80.1% (n=23) for T1 tumors and only 16.2% (n=28) for T4 tumors, 68.7% (n=55) at the N0 stage and 42.8% at >N0 (n=44, chi(2) test P=0.01, Fischer's exact test P=0.014). Highly differentiated carcinomas (n=26) had a survival probability of 78.9% and G2 and G3 tumors of only 48.9% (n=73, chi(2) test P<0.001). Tumor size and lymph node metastases are decisive.

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...
