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.

GTP binding protein (G-protein) associated with membrane and involved in signal transduction was isolated from bovine brain, and molecular weight of G protein was observed. As the results, cell membranes were homogenized from bovine brain tissues and proteins of membrane were gained using 1% cholate, and progressed the chromatography. The purification process was performed by step, DEAE-Sephacel, Ulttrogel AcA 34 and heptylamine-Sepharose column chromatography. The chromatographic fractions were confirmed by GTP binding assay and SDS-polyacrylamide gel electrophoresis. Molecular weight of Goa was revealed 39,000 dalton and GR 36,000 dalton. One more step of heptylamine-Sepharose was enforced to purify the GTP binding protein. Finally I gained the GTP binding protein isolated subtype of Goalpha and Gbeta.

Estrogen receptor(ER) and progesterone receptor(PR) were studied immunohistochemically using specific antireceptor monoclonal antibodies in leiomyomas and myometrium from same patients from 38 women in various stages of the menstrual cycle, menopause and pregnancy. Two postpartum uteri are also included. Immunohistochemical localization was quantified as to intensity of staining and tissue distribution, and the results were compared with those of PCNA index. In all samples, ER and PR localized within the nuclei of target cells. The histochemical score of ER in leiomyoma was significantly greater than that found in myometrium. But ER in leiomyoma was expressed in cyclic fashion(r=0.45, P=0.006), like as in myometrium, throughout the menstrual cycle, paralleled by a concomitant, though delayed. In contrast, PR content constantly maintained in myometrium and leiomyoma throughout menstrual cycle, and there was no significant difference between them. However, leiomyoma and myometrium of pregnancy showed a significant reduction in the amount of ER and PR localized. PCNA index in leiomyoma(14.9+/-24.4) was also significantly higher than that found in myometrium(2.1+/-3.3). The index declined throughout the secretory phase. The leiomyoma had increased PCNA index during pregnancy, while the increasing rate in leiomyoma was lower than that of myometrium. The growth potential of leiomyomas is appearently higher than that of myometrium under the high progesterone level. The most of neoplasm with high PCNA index(10 above) contained absolute or relative abundant PR or ER content. Alteration of receptor content may be an important mechanism in steroid dependent growth of leiomyoma and may provide information useful in the clinical management of this neoplastic disorder.
