Cancer has become a major cause of death in Korea since 1989. Despite the major advances in the treatment of cancer, prevention and early detection is the most effective strategy to decrease the mortality from cancer. The indicence of invasive cervical cancer has declined since the 1950s, and indirect evidence suggests that this decline is the result of the institution of screening with cervical smear. However, cervical cancer continues to be a major health problem in the developing world today, where screening is not universal. Among Korean women, the incidence of cervical cancer is still high and was the 3rd most common cancer following stomach and breast cancer in 2000. If preinvasive conditions would be included, the disease would be the most frequent. The first organized screening programmes were initiated in 1949 at British Columbia, Canada. Since then, cervical cancer screening programmes have been implemented in almost all developed countries. In Korea, opportunistic screening began in the late 1950s, and organized screening began in 1998 by Health Insurance without a consensus meeting. The guidelines for the screening of cervical cancer were developed by National Cancer Center and the Koean Society of Obstetrics and Gynecology in May, 2001 ; and the national screening programmes were developed by the Supporting Evaluation Board of National Cancer Screening Program in December, 2001. This article introduces these programmes.

Papillary cystadenoma of the epididymis is a rare benign tumor that represents the epididymal component of von Hippel-Lindau Syndrome. A case of epididymal papillary cystadenoma is presented in a 36 years old man. He also had pancreatic cysts, the pancreatic component of von Hippel-Lindau syndrome. His younger brother, who died of intracranial hemorrhage at age 27, revealed hemangioblastoma of the cerebellum, angioma of the retina and renal cell carcinoma on radiologic studies. These findings suggest familial occurrence of von Hippel-Lindau syndrome.
Hemangioma

A total of 697 cases of intracranial and intraspinal tumors was obtained from the pathology file of Seoul National University Hospital and Children's Hospital during the period of 8 years from 1980 to 1987. These tumors were classified according to WHO classification. This study was performed to understand the recent trend of the relative frequency of the central nervous system tumors among Koreans and to compare it with the previous studies in Korea and other countries. There were 663 intracranial tumors and 34 intraspinal tumors. More common intracranial tumors were pituitary adenoma, meningioma, astrocytoma and medulloblastoma, each representing 23.4%, 20.8%, 11.8%, and 5.6%, respectively. In juvenile age group (under 15 years of age), medulloblastoma, astrocytoma, ependymoma and craniopharyngioma were more commonly encountered to be 25.6%, 21.6%, 13.6% and 12%, respectively. Both sexes were equally affected among adult group, but male preponderance was observed among juvenile group (1.49:1). Nine cases of primitive neuroectodermal tumor, a unique tumor which is not listed in WHO classification, were observed and all of them occurred before the age of 20. There were 27 metastatic tumors. Our previous study encompassing previous 17 years, 1963 to 1979, showed similar overall results except for intraspinal tumors that were more commonly encountered in previous series.

Hyperplasia*

A clinico-pathologic study with an immunohistochemical examination for c-erbB-2 expression in 54 cases of ductal carcinoma in situ and 16 cases of Paget's disease of the breast was performed. c-erbB-2 oncoprotein overexpression was observed in 45% (24/54) and 88% (14/16) of ductal carcinoma in situ and Paget's disease, respectively. The overexpression of c-erbB-2 oncoprotein was significantly correlated with the nuclear grade of tumors and inversely with the status of the estrogen receptor. c-erbB-2 was positive in 4 out of 5 patients with metastasis to axillary lymph nodes and 3 out of 4 patients who died of the disease. Prognostic significance of c-erbB-2 oncoprotein in ductal carcinoma in situ was highly suggested. The expression of c-erbB-2 oncoprotein in Paget's disease was well correlated with coexisting infiltrating or in situ ductal carcinoma. The high positive rate of c-erbB-2 oncoprotein in ductal carcinoma with Paget's disease could be understood with a recent hypothesis that c-erbB-2 oncoprotein is involved in promotion of cell motility and the spread of carcinoma cells.
Neoplasm Metastasis

Malignant rhabdoid tumor (MRT) is a rare and highly aggressive neoplasm of infancy and childhood. Although it was originally described and most frequently reported in the kidney, it may occur in various extra-renal sites such as the liver, thymus, and soft tissue. In the last decade primary central nervous system (CNS) MRTs have been reported in both the supra- and infratentorial compartments. Patients with CNS MRT were generally below the age of two and reports in adults are extremely rare. This is a case of primary cerebellar MRT in a 24-year-old woman, who had presented with intermittent headache, vocal cord palsy, and cerebellar dysfunctions such as abnormal finger to nose test and tandem gait. By magnetic resonance imaging scan, a well-enhancing solid mass was demonstrated at the posterior fossa filling the 4th ventricle, which extended into the medulla and cervical cord via the foramen of Magendie. Histologically, the monotonous polygonal tumor cells were arranged in diffuse sheet with occasional hemorrhagic necrosis. The nuclei were vesicular and eccentrically located due to eosinophilic, PAS-positive, intracytoplasmic inclusions with prominent nucleoli. They were diffusely or focally immunoreactive for vimentin, neurofilament, cytokeratin, GFAP, synaptophysin, and smooth muscle actin, while epithelial membrane antigen and desmin were negative. Ultrastructurally, the polyhedral tumor cells were densely packed with primitive intercellular junctions. Scanty fibrillar intermediate filaments were intermingled with cellular organelles. Postoperatively, craniospinal irradiation and systemic chemotherapy have been done and she has been free of tumor recurrence during the 13 months' follow-up periods.

An experimental allergic encephalomyelitis was induced by bovine myelin basic protein (MBP) and bovine galactocerebroside (GC) on male guinea pigs. Animals were divided into five experimental and one control groups. Among the five experimental groups, three were inoculated with 75 micrograms, 150 micrograms and 300 micrograms of MBP, respectively, to see the dose dependency of demyelination. The fourth group was inoculated with mixture of 75 micrograms of MBP and 180 micrograms of GC and the fifth group with 180 micrograms GC. All inocula was injected intradermally in emulsion state mixed with equal amount of complete Freund adjuvant. Control group was injected with adjuvant only. Clinical symptoms began to appear from 15th day after inoculation and animals were sacrificed on maximum neurologic deficit or 4 to 5 days after the onset of symptoms. Demyelination was observed in 6 out of 8 animals inoculated with MBP/GC mixture, while only 3 out of 24 animals inoculated with various dosage of MBP showed demyelination. The difference was statistically significant. Serum antibodies to MBP and GC were measured by ELISA method. All of the eight animals inoculated with MBP/GC mixture and two animals inoculated with GC had low titer of anti-GC antibodies, while all animals inoculated with MBP, MBP alone or MBP/GC mixture, had high titer of anti-MBP antibodies. Therefor it is concluded that the demyelination is augmented by GC and is not significantly dose-dependent on MBP.

Fibromatosis can occur at various sites, but intracranial fibromatosis is exceptionally rare. Here, we report a case of intracranial fibromatosis arising in the suprasellar area of a 52-year-old woman who had undergone a surgery at that site. A computed tomography scan revealed a heavily calcified, highly enhancing, poorly demarcated mass in the left sellar area that extended into the left suprasellar, parasellar areas, and orbital apex and completely encased the left distal inferior cerebral artery. Histologic and immunohistochemical features were compatible with those of fibromatosis, although the cellularity was focally higher than usual. The etiology of extra-abdominal fibromatosis is unknown, but physical injuries such as trauma and irradiation have been reported to be associated with its occurrence. Although fibromatosis is rare in the intracranial area, it should be considered as a differential diagnosis when an intracranial mass occurs at a previously injured site.
