Abstract:
Little is known regarding disease-specific cumulative survival and factors affecting survival in Australian populations with oral squamous cell carcinoma. Kaplan Meier and Cox proportional hazards models were used to determine survival factors in 116 consecutive patients treated surgically at a single institution. Overall 5-year disease-specific survival rate was 83.3%. Five-year disease-specific survival probability was 88.7%, 83.8%, 83.3% and 76.5% for stage I, II, III and IV, respectively. Univariate analysis revealed that local and regional recurrence, distant metastases, N stage, margin status, radiotherapy, perivascular spread and extra-capsular spread (ECS) significantly influenced survival. Significant multivariate factors included local and regional recurrence, positive margins, and ECS. Better survival rates were found than in previous, older Australian reports. Close observation for early recurrence and aggressive management of patients with recurrence, positive margins and ECS, is advised.

Cancer Therapies
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
