PURPOSE: The aim of this study was to investigate treatment results, toxicity and efficacy of hyperfractionated radiation therapy combined with paclitaxel for paraaortic node recurrence in cervix cancer. MATERIALS AND METHODS: Between September 1997 to March 1999, 12 patients with paraaortic node recurrence in cervix cancer who previously received radical or postoperative radiotherapy were treated with hyperfractionated radiation therapy combined with paclitaxel. Of these, 2 patients who irradiated less than 30 Gy were excluded, 10 patients were eligible for this study. Median age was 5 1 years. Initial FlGO stage was 1 stage IB1, 2 stage IIA, 7 stage IIB. For initial treatment, 7 patients received radical radiotherapy and 3 received postoperative radiotherapy. The paraaortic field encompassed the gross recur rent disease with superior margin at T 12, and inferior margin was between L5 and S 1 with gap for previously pelvic radiation field. The radiation field was initially anterior and posterior opposed field followed by both lateral field. The daily dose was 1.2 Gy, twice daily fractions, and total radiotherapy dose was between 50.4 and 60 Gy(median, 58.8 Gy). Concurrent chemotherapy was done with paclitaxel as a radiosensitizer. Dose range was from 20 mg/m to 30 mg/m (median, 25 mg/m'), and cycle of chemotherapy was from 3 to 6 (median, 4.5 cycle). Follow-up period ranged from 3 to 21 months. RESULTS: Interval between initial diagnosis and paraaortic node recurrence was range from 2 to 63 months (median, 8 months). The 1 year overall survival rate and median survival were 75% and 9.5 months, respectively. The 1 year disease free survival rate and median disease free survival were 30% and 3 7 months, respectively. At 1 month after treatment, 4 (40%) achieved a complete response and 6 (63%) experienced a partial response and all patients showed response above the partial response. There was distant metastasis in 6 patients and pelvic node recurrence in 2 patients after paraaortic node irradialion. There was 2 patients with grade 3 to 4 leukopenia and 8 patients with grade 1 to 2 nausea/ vom ting which was usually tolerable with antiemetic drug. There was no chronic complication in abdomen and pelvis during follow up period. CONCLUSION: Hyperfractionated radiation therapy combined with paclitaxel as a radiosensitizer showed high response rate and few complication rate in paraaortic node recurrence in cervix cancer. Therefore, present results suggest that hyperfractionated radiation therapy combined with paclitaxel chemotherapy can be used as optimal treatment modality in this patients.

A clinical observation was made on the patients with bladder tumor admitted to the Department of Urology, Seoul Adventist Hospital during the periods from January 1978 to December 1981. The following results were obtained. 1. During the periods, 930 patients were hospitalized, and there were 36 cases of bladder tumor giving an incidence rate of 3.9%. 2. There were 25 males and 11 females with a ratio of 2.3:1. 3. Age distribution was between 23 and 77 years, the highest incidence rate was in the age group of 60-69years. 4. The clinical manifestation included gross hematuria (88.9%), frequency (69.4%), dysuria (44.4%) and the others. 5. On I.V.P. findings, 29 cases (80.6%) revealed normal upper tract, 6 cases (16.7%) were unilateral hydronephrosis, and 31 cases (86.1%) revealed filling defect in the bladder. 6. The tumors were located mainly at the lateral wall and trigonal area of bladder (50.0%). 7. Of 36 cases of bladder tumor, 30 cases (83.3%) were transitional cell carcinoma, 3 cases (8.3%) squamouscell carcinoma, and each 1 case (2.8%) adenocarcinoma, metastatic carcinoma and leiomyoma. 8.

PURPOSE: Alteration of p53 and telomerase activity may be responsible for gastric carcino- genesis. In this study, we tried to observe modulation of telomerase activity by wild type p53 in gastric cancer cell lines. MATERIALS AND METHODS: We used five gastric cancer cell lines (KATO-III, AGS, SNU-1, SNU-5, SNU-16). In order to find p53 mutation, we used western blot and PCR-SSCP. The TRAP-eze kit which supplied by Oncor (Gaithersburg, MD) was used to detect telomerase activity of the five gastric carcinoma cell lines. The wild type p53 gene was transfected by electroporation method. RESULTS: The expression of p53 protein was increased in four gastric carcinoma cell lines and one cell line (KATO-III) did not express. We found p53 point mutation in exon 5 and 8, and the p53 gene was deleted in KATO-III. The telomerase activity were observed in all five gastric carcinoma cell lines and there were no difference in telomere repeat length among five cell lines. After transfection with wild type p53, we could not find the change of telomerase activity in KATO-III. CONCLUSION: Although activation of telomerase activity and mutation of p53 gene may be needed in gastric carcinogenesis, the telomerase activity was not affected by restoration of p53 function in gastric carcinoma cell lines.

We evaluated the renal function could be estimated by the visual analysis of the perfusion images of Tc-99m DTPA renal scan. Renal scan, creatinine clearance(CCr) and serum creatinine(s-Cr) were obtained in 105 patients. Intensity of renal activity(RA) at 6 sec perfusion image after the first visualization of abdominal aortic activity(A or A) was considered as the parameter for estimating renal function. Intensity of RA was scored from grade(Gr.) 1 to 3(Gr. 1: RAsplenic activity(SA), Gr. 2: RA A or A, Gr. 3: RA60 mL/min. The P.P.V. of Gr. 2 RA was 92% for s-Cr from 1.5 to less than 3.5mg/dL and 83% for CCr value from 20 to less than 60mL/min. The P.P.V. of Gr. 3 RA was 95% for s-Cr3.5mg/dL and 95% for CCr<20mL/min. As the intensity of RA of perfusion images decreased, renal function more decreased. We could detect renal dysfunction by visual analysis of perfusion images of renal scan.

The present study has been undertaken to pursue the cytotoxic effects of cis-Platin on the osteoid formation in metaphysis of rat tibia. By using the immunohistological staining method for type I collagen in rat tibial osteoid, the author detected the deposition of type I collagen, which is the collagenous constituent of endochondral osteoid, after administration of cis-Platin in experimental animals. For the immunological reactions of type I collagen, we used the rabbit anti-rat collagen type I polyclonal antibody as primary antibody and biotinylated goat anti-rabbit IgG as secondary antibody. The distributions of immunohistological reactions in the each of metaphyseal osteoids were analyzed with an image analyzer, and we studied the variances of type I collagens by statistical probabilities. In 12 hours after cis-Platin injection, immunoreactive area in the osteoid of metaphysis was distinctly decreased. Immunoreactive area of type I collagen in osteoids of 1 day and 3 days group metaphysis was increased more than that of 12 hours group and the type I collagen in the metaphysis showed weak immunoreactions of type I collagens with an image analyzer. In the osteoids of 7 days group after cis-Platin injection, the immunoreactive area was similar to that of control group. It is consequently suggested that cis-Platin would induce the decrease of type I collagen in the osteoid. But the type I collagen in tibial osteoid shows the increase from a few days after cis-Platin injection.

The recent introduction of chemotherapy in the treatment of gynecological malignancies has gained wide acceptance along with prstoperative and prostperative adjuvant therapy and with preradiation and concurrent chemoradiation therapy. But, the side effects of chemotherapy including bleeding and infection due to, bone marrow suppression have reaulted in delayed treatment and a reduction in the chemotherspeutic agent used. Recent efforts overcome this bone marrow suppression have led to development of the various human colony-stimulating factor indluding recombinant granulocyte colony-stimulating factor. The author investigated the clinical benefita and toxicity of G-CSF used during chemotherapy of various gynecological malignancies at the Departent of Obstetrics & Gynecology at Hanyang University between August, 1991 and July, 1992. The results were as follows ; 1. An increase in the number of neutrophils following a single injection of G-CSF was noted in 19 out of 21 cases(600~1,000/mm3 before injection, 4,500~12,000/mm3 after injection). The remaining 2 cases showed an increase after 3~5 continuous injections. 2. To assess the increase in neutrophils according to the dosage of G-CSF given, 100 and 300microgram/m* of G-CSF were injected in each trial of chemotherapy in a single case of ovarian cancer. The results were a 1.5 time increase when injected when injected with 300microgram/m*. 3. After injecting into a patient with recurrent endometrial cancer who was managed with 15gm of ifosfamide, 50gm of cis-platinum, 50gm of adriamycin and 3gm of mesna following surgery, no evidence of neutropenia could be found after 4days of prophylactic G-CSF injections. 4. Patients with cervix cancer with metastasis to the lung were first treated with GM-CSF in one trial and G-CSF in the nest. Patients treated with Gm-CSF for a period of 7 days showed leukocytosis(3,600/mm3) but the number was reduced to 1,400/mm3 after 7 days. On the other hand, patients treated with G-CSF showed an increase of 5,700/mm3 within one day and this figure did not decrease until 20 days later. 5. The toxic effects of G-CSF included on case of severe back pain was easily managed by administration acetaminophen. Others were headache, chills, general weakness and redness of the oral mucosa and injection area. Most of these symptoms disappeared within 2 days. The G-CSF is effective in neutropenia during chemotherapy thereby decreasing the incidence of treatment delay or dose reduction. It also increases the amount of chemotherapeutic agent administered and its toxicity is more tolerable making a rigid systemic chemotherapeutic regime possible.
