Delayed Diagnosis of oral Malignancy: Its crucial effect on management and prognosis Dr Hassan El Abdin Introduction Malignant condition of the oral cavity comprises about 5.6% of all malignant tumours of the human body, in Saudi Arabia1. It is the third most common tumour in females and the fourth in males.1 Ajarim,D Proce Saudi Oncol Symp 1995 Introduction In the United States, it is relatively uncommon, and represent 2.5% of the total.2 Shafer JADA 1975 In the Scandinavian countries, it comprises about 2% of all malignant tumours, and the prognosis is poor compared with malignancies in other sites.3 Bruun Oral Surg 1976 Introduction Delayed diagnosis of malignant condition and particularly of the oral cavity, is of crucial importance for the clinical management, cost of care and the outcome.

It is varies between 15% - 52% which is the fifth lowest 5-year survival rate. Introduction The survival of oral cancer patient depend on early diagnosis and treatment. Most studies on oral malignancy prove that the mortality rate drops effectively, if the lesions are recognized sex, age, symptoms, referral diagnosis time lapse from first symptoms until consultation final diagnosis, previous treatment, final treatment and survival period Definitive treatment took place at KKUH and Riyadh Military Hospital Result: Distribution of cases according to sex Sex Number% Male 2362.2 Female1437.8 Total37100% Result: Distribution of patients according to age AgeNumber% Group I: 5 10 years25.4 Group II: 11 20 years 25.4 Group III: 21 30 years38.1 Group IV: 31 40 years1027.0 Group V: 41 50 years1643.3 Group VI: 51 and up410.8 Total37100% Results: Distribution of cases according to race RaceNumber% Saudi2978.4% None Saudi 821.6% Total37100% Result: Distribution of case according to histogenesis Tumour diagnosis Number % Mucoepidermoid carcinoma1437.8 Squamous cell carcinoma1232.4 Extra-nodal non-Hodgkin lymphoma410.8 Rhabdomyosarcoma25.6 Adenoid cystic carcinoma12.6 Acinir cell carcinoma12.6 Osteosarcoma12.6 Metastatic adenocarcinoma25.6 Total37100% Result: Sites of Oral Tumours SiteNumber% Palate19 51.4 Floor of the mouth2 5.4 Tongue anterior, lateral border3 8.1 Cheek2 5.4 Retromolar area 5: 1991 Conclusion: Treatment of early lesion carries an excellent prognosis Dentists will require greater training in the recognition of warning signals and causes of delayed diagnosis of early and even late malignant conditions of the oral lesion Conclusion: Medical schools exposes their students to very little education
