2.Method of tumor volume evaluation using magnetic resonance imaging for outcome prediction in cervical cancer treated with concurrent chemotherapy and radiotherapy.
Radiation Oncology Journal 2012;30(2):70-77
PURPOSE: To evaluate the patterns of tumor shape and to compare tumor volume derived from simple diameter-based ellipsoid measurement with that derived from tracing the entire tumor contour using region of interest (ROI)-based 3D volumetry with respect to the prediction outcome in cervical cancer patients treated with concurrent chemotherapy and radiotherapy. MATERIALS AND METHODS: Magnetic resonance imaging was performed in 98 patients with cervical cancer (stage IB-IIIB). The tumor shape was classified into two categories: ellipsoid and non-ellipsoid shape. ROI-based volumetry was derived from each magnetic resonance slice on the work station. For the diameter-based surrogate "ellipsoid volume," the three orthogonal diameters were measured to calculate volume as an ellipsoid. RESULTS: The more than half of tumor (55.1%) had a non-ellipsoid configuration. The predictions for outcome were consistent between two volume groups, with overall survival of 93.6% and 87.7% for small tumor (<20 mL), 62.9% and 69.1% for intermediate-size tumor (20-39 mL), and 14.5% and 16.7% for large tumors (> or =40 mL) using ROI and diameter based measurement, respectively. Disease-free survival was 93.8% and 90.6% for small tumor, 54.3% and 62.7% for intermediate-size tumor, and 13.7% and 10.3% for large tumor using ROI and diameter based method, respectively. Differences in outcome between size groups were statistically significant, and the differences in outcome predicted by the tumor volume by two different methods. CONCLUSION: Our data suggested that large numbers of cervical cancers are not ellipsoid. However, simple diameter-based tumor volume measurement appears to be useful in comparison with ROI-based volumetry for predicting outcome in cervical cancer patients.

Syringomas are relatively common benign adnexal tumors that are usually located on the lower eyelids, although affecting other areas, including cheek, axillae, abdomen and vulva. Acral syringomas, located on distal extremities are vary rare and there is only one case reported in Korea. We report a case of a healthy 21-year-old woman with multiple, reddish brown syringomas located on both forearms and the dorsa of hands. The histologic findings were typical of syringomas.

BACKGROUND: The relationship and differentiation among various dendritic cells of the dermis are unclear. Recently it has hecome possible to identify different subpopulat,ions of dermal dendritic cells using anti-CD34 and anti-factor XIIIa antibodies. OBJECTIVE: To elucidate which cell types the fibrous dermal turnors consist of we compared the staining patterns of these antibodies as well as of anti-Mac 387 antibody which are labeled as inflammatory cells of the monocyte-macrophage lineage. METHODS: Tumors studied included dermatofibrosarcoma protuberans(DFSP, n=2), dermato-fibroma(n=22), neurofibroma, n=27), acrochordon(n=15), keloid, hypertrophic scar(n=10), juvenile xanthogranuloma(n=1, and malignant fibrous histiocytoma (MFH, n=1). We performed immunoperoxidase staining(AUSC technique) with polyclonal anti FXIIIa antibody, monoclonal anti-CD34 antibody, and monoclonal anti-Mac 387 antibody on the formalin-fixed-paraffin-embedded tissue specimens of these fibrous tumors. The intensity of staining was graded as negative, weakly staining, or strongly stainiring. RESULTS: FXIIIa reactivity was strongly present in dendritic and spindle-shaped cells of all dermatofibromas and some nurofibromas(11 of 27 specimens), but absent from the other fibrous tumors. Among these tumors, one of the two DFSPs was uniquely expressed CD34. Dendritic and spindle-shaped cells within tiese tumors were MAC 387 negative. In inflammatory conditions, variable numbers of MAC 38 positive cells were observed, corresponding to histiocytes and mac-rophages, but the labeling of ipithelioid cells and multinucleated foreign body giant cells were variable. CONCLUSION: The findings of significant numbers of FXIIIa positive cells in dermal fibrous tumors studied suggest that thet may be diagnostic utility associated with the use of this antit)ody. In addition, CD 34 expression by the tumor cells can be an extremely useful marker in establishing a definitive diagnosis of IFSP.

9.Angiographic Demonstration of the Posterior Cerebral and Posterior Communicating Arteries in Normal and Hydrocephalus Cases.
Journal of Korean Neurosurgical Society 1974;3(1):7-14
Carotid angiography is a most important diagnostic procedure for investigation of intracranial lesions and for understanding the cerebral circulation. Of the cerebral arteries, only the posterior cerebral artery is, both functionally and anatomically, a border artery between the carotid and vertebral circulatory systems, so it is more important for an understanding of the cerebral circulation. Early in the development of the fetal circulation, the posterior cerebral artery arises from the internal carotid artery(carotid segment), with the connection to the basilar artery(basilar segment) developing later. In many cases, however, it derives its supply from both systems simultaneously. Angiographic demonstration of the posterior cerebral artery is influenced by certain pressure factors of the intracranial cavity and other technical factors, for example, site of puncture, needle size, injection time and force used and position of the head, ect. Here the author has analysed the factors of age, sex, puncture site and right of left side and a degree of hydrocephalus. Carotid angiography has been performed for definite indication, hence, no cerebral angiography has been performed on any entirely asymptomatic subject. The normal controls used in this investigation consist of angiographies done in subjects with symptoms but no evidence of vascular lesions or other abnormality. The author found a high incidence of the posterior cerebral arteries demonstrated in hydrocephalus, in spite of increased pressure and changed courses of the cerebral arteries. So, the cerebral arteriograms of normal cases are compared with those of hydrocephalic subjects and the chances of demonstrating the posterior cerebral artery in both groups are analysed. Engeset A.(1948), Saltzman(1959), Yasargil & Krayenbuhl(1964) and others reported the demonstration of the posterior cerebral artery but report of a relationship of the artery with hydrocephalus was not found. This study comprises 2,350 conventional carotid angiographies carried out from 1968 to 1973 in the neurosurgery department of Severance Hospital, Seoul, Korea. Out of these 2,350 angiographies, 1,288 were normal and 160 were indicative of hydrocephalus. The incidence of angiographic demonstration of the posterior cerebral artery in normal Koreans is 34.2% and in hydrocephalus, 45.6%. This is a higher incidence than is reported in the literature concerning conventional carotid angiography. The number of cases where the posterior communicating artery alone was filled was so small that there was no point in separating them according to age and sex, etc. Generally the hydrocephalic group showed a higher incidence of the posterior cerebral and posterior communicating arteries than the normal group. In all cases, the effect of sex difference is not significant but the effect of age is. The posterior cerebral artery was more visible in the younger groups and occurred most frequently in the youngest group, while the incidence dropped slightly in the higher age groups, in both normal and hydrocephalus groups. Filling of the posterior cerebral arteries in subjects aged 10-30 is markedly more frequent than in the 40-60 age range in both the normal and hydrocephalus groups. The posterior cerebral artery was demonstrated in 148 out of 384(38.6%) internal carotid arteriograms and in 292 out of 904(32.3%) common carotid arteriograms. This difference is highly significant and is similar to the results of Saltzman(1959). No significance of the right or left side difference could be found. The increasing tendency of the filling of the posterior cerebral artery in the more severe forms of hydrocephalus compared with the milder types was noted. In this report, the statistical significance was evaluated by means of the z-test.
