Research at Tu du hospital from 1998 to 2004 on 212 ovarian tumors with 48 ovarian cancers, from 16 to 82 years of age. Anapathology result: epithelial tumors (72,91%) are the most common with serious and mucinous cystadenocarcinomas; germ cell tumors (18,75%) had the second rank composed mainly of mixed germ cell tumors, endodermal sinus tumors and immature teratomas. 3 cases of genital stromatic tumor include all granuloma One case of krukenberg tumors. During the period 1998 to 2000, 50% of ovarian cancers are detected at an early stage I and II. This proportion has increased to 58% in the period from 2002 to 2004

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

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.

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

Background: Postperitoneal tumors are diseases that are difficult diagnosis, vague and unspecific clinical signs. Objective: To take out experience for clinical practice based on clinical, imaging diagnosis, pathological characteristics and management for postperitoneal tumors. Subjects and method: A retrospective study included 93 cases that diagnosed and treated for postperitoneal tumors at Cho Ray Hospital from January 2000 to November 2006. Clinical, subclinical characteristics and theirs related factors; diagnosis, operation and prognosis for postperitoneal tumors were analysed. Results: The patients\ufffd?average age was 49.98\xb116.37 years (ranged 1-85 years); the ratio of male to female was 0.86. The average time from having pain symptom to admitting hospital was 4.49\xb110.01 months (ranged from 3 days to 60 months). Clinical symptoms were fatigue (51.5%), fever (15%), jaundice (45%), anemia (23.5%), weight loss (58%), abdominal pain (75%), abdominal distention (39%), digestive disorders (31%), touching tumor (50.5%)\ufffd?The diagnosis at admitting were right (32%), wrong (60%) and unclear (8%); the preoperative diagnosis were 70%, 22% and 8%, respectively. Pathologically, 39 of 93 cases (42%) were benign tumors, and 58% were malignant tumors. 61.3% of cases removed completely tumors, 2.15% removed partially tumors. The postoperative outcomes were good (62.6%), unimproved (28.57%), and bad (3.29%). There were some complications, included perioperative bleeding (2 cases - 2.19%), postoperative complication (3 cases - 3.29%), cracked colonic junction (1 case), renal bleeding (1 case) and peritonitis (1 case). Conclusions: The surgical treatment was main method for postperitoneal tumors. The complete tumor removing based on tumor\u2019s nature, stage and related structures.

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.
