At Hanoi K Hospital from 1992 to 1996 years 149 sets of patho histological samples from patients with basal cell carcinoma were studied. The study showed that this cancer was developed usually in elderly subjects of average 61,8 years old of age and with male/female ratio 1,04. The carcinoma appeared mainly at the face-neck area (98,6%) especially in skin area of nose, cheek and eye (83,2%), a high portion (36,9%) of patients was hospitalized early, but the late portion was considerable – 12,1%. A rate of 16,8% appeared within 60%, especially the large size cancers – 38,9% for the size > 5cm. The recurrent cancer of < 2 cm in size developed only within 2 first years- some larger size cancer could be appeared late, after 3-4 years

From Jan. 2001 to Dec. 2002,at the Hospital K in Hanoi,112 cases of thyroid carcinoma (99 females and 13 males, among them 79,45% aged 21-60 years old) were studied. Among all 5 pathohistological types of thyroid carcinoma, papillome-carcinoma occupied 83,14% in both two genders, cystic-carcinoma 14,28% only in female. Undifferenciated carcinoma occupied 2,56% ;rather characterized for each type. Differenciated carcinoma was more common, with specific characters easy to identify. Undifferenciated carcinoma had got polymorphism characteristic cells, large necrosis, polynucleus

149 patients aged 30-80 years (76 males, 73 females) underwent a surgical treatment of basocell skin carcinoma in the period of 1992-1996. Results showed that: this carcinoma was common on the elderly, mainly on the skin area of face and neck, especially the areas of nose, cheek and eyes. A high rate of patients admitted in hospital early. After operation, the rate of recurrent accounted for 16.8%, the most occurred within 2 years after, especially of the tumors of > 5 cm. The recurrent tumors  2cm occurred only within the first 2 years, and later for the larger tumors.

66 patients with pleural cancers (40 males, 26 females) were treated at Bach Mai hospital from 1996 to 2000. Pleural cancer was rare and concentrating at the age group > 40, more common in male than in female. 70% of pleural cancer patient had got a history of chronical pleural inflammation. The common symptoms were chest pain, cough, dyspnoea, syndrome of “3 reduces”. Among these 66 patients, some could get secondary pleural cancer caused the metastasis and invasion from other organs. None case was consistent with previous diagnosis from lower health care service level.

195 patients with tonsil carcinoma were treated by simple external radiation at K Hospital from January 1990 to January 2001. Results showed: the rate of response to simple external radiation in all episode was 58.9%, partial response 41.1%, no unresponsive case or progresive case. The rate of responsive effect of external radiation on tumor was T1, T2 - 100%, T3 - 47%, T4 - 0%, N1 - 100%; N2 - 82.4%; N3 - 20.4%. The responsive rate of external radiation on tumor and adenomas was depended mainly on the sign, the invasion of the tumor and the adenome, but no relation with histopathological type.

Primary liver cancer, most of which is hepatocellular carcinoma (HCC), is the third common leading cancer in Korea. During the last two decades, the incidence rate of primary liver cancer has shown a modest decrease, but its mortality rate has slightly increased. The incidence of HCC, according to age, peaks in the late sixth decade in men and in the early seventh decade in women. Hepatitis B virus (HBV) is the most important risk factor, which represents approximately 70% of all HCC, and hepatitis C virus (HCV) and alcohol are the next in order of major risk factors for the development of HCC in Korea. HBV-associated HCC occurs 10 years earlier than HCV-associated HCC due to a more prolonged exposure to HBV, which is vertically transmitted almost from HBsAg-positive mother in HBV-endemic area. National Cancer Control Institute, which was reorganized in 2005, is now working for several national projects such as National Cancer Registration Program, National R&D Program for Cancer Control and National Cancer Screening Program. International collaboration for the clinico-epidemiologic research would be needed to provide the specific measures for managing HCC in diverse etiologic situations. Finally, the mechanisms of hepatitis virus-associated hepatocellular carcinogenesis might be clarified to provide insights into the advanced therapeutic and preventive approaches for HCC in Korea, where the majority of HCC originate from chronic HBV and HCV infections.
