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.

PURPOSE: Extracorporeal shock wave lithotripsy(SWL) is currently prorposed for the first line treatment of most renal and ureteral stones. In general, SWL is very effective and non-invasive method than open surgery or endoscopic lithotripsy. We experienced 350 cases of SWL for 46 months and announced it. MATERIALS AND METHODS: We retrospectively reviewed the data of 324 patients(350 stones) who had been diagnosed as renal or ureteral stones and underwent SWL using Tripter Compact(R) lithotriptor from September 1994 to July 1998. Male to female ratio was 1.9:1 and patient`s ages ranged from 18 to 82 years(mean 43.7 years). We underwent SWL only with parenteral analgesics for pain control. RESULTS: In 350 stones, renal stones were 90 cases(25.7%) and ureteral stones were 260 cases(74.3%). In 90 renal stones, calyceal stones(include 1 staghorn stone) were 62 cases(68.9%) and renal pelvic stones were 28 cases(31.1%). In 260 ureteral stones, upper ureteral stones were 209 cases(80.4%), mid ureteral stones were 10 cases(3.8%), and lower ureteral stones were 41 cases(15.8%). The stones from 10 to 19mm in diameter were the majority of renal stones(53.3%), whereas in ureter, the stones smaller than 10mm in diameter were most common(41.5%). Less than 3 treatment sessions were needed for 147 cases(93.0%) of stones smaller than 10mm and for 146cases(76.0%) stones larger than 10mm. Less than 3 sessions were needed for 68 cases(75.6%) of renal stones and for 225 cases(86.5%) of ureteral stones. All renal stones were fragmented and the success rate for upper ureteral stones was 93.3%(195/209), for mid ureteral stones was 80.0%(8/10), and for lower ureteral stones was 80.5%(33/41). According to the size of stone, the success rate for the stones smaller than 10mm in diameter was 96.2%(152/158) and for the stones larger than 10mm was 90.6%(174/192). Total success rate was 93.1%(326/350). The complications after SWL were gross hematuria over 24hours(64 cases, 18.3%), flank pain(52 cases, 14.9%), gastrointestinal disturbances(7 cases, 2%), and Steinstrasse(31 cases, 8.9%). The causes of failure were incomplete fragmentation(21 cases, 87.5%) and mucosal impact(3 cases, 12.5%) of stones. Re-treatment rate was 59.7% and auxiliary procedure rate was 8.0%(efficiency quotient was 0.56). CONCLUSIONS: Our experiences shows extracorporeal shock wave lithotripsy is a safe and effective method for the treatment of renal and ureteral stones, and we expect the better outcome by development of techniques and equipments.

PURPOSE: We conducted a phase II study in previously untreated patients with unresectable stage IIIB or IV non-small cell lung cancer to evaluate the response rate and toxicity of the combination chemotherapy regimen of etoposide, ifosfamide and cisplatin. MATERIALS AND METHODS: From September 1993 to December 1996, twenty patients with advanced non-small cell lung cancer (stage IIIB 5 and IV 15) (squamous cell 8, adeno- carcinoma 12), were enrolled in this study. There were 13 (65%) males and 7 (35%) females, and median age of patients were 56 years (range: 34~66). Eighteen patients had performance status (ECOG) 0~1, two patients had performance status 2. Treatment was consisted of cisplatin (20 mg/m2 i.v., day 1~4), VP-16 (etoposide) (75 mg/m2 i.v., day 1~4), ifosfamide (1000 mg/m2 i.v., day 1~4) with mesna. This treatment was repeated every four weeks. RESULTS: The overall response rate was 25%. Complete response rate was 5% (1/20) and partial response rate was 20% (4/20). The median cycle of response was 4 (2~6) cycles. The median overall survival time was 28 weeks (9~98 weeks). The median time to progression was 10 weeks (3~50 weeks). Toxicities were evaluated by WHO criteria. Toxicity > GradeIII included: leukopenia 1.6%, thrombocytopenia 3.2%, nausea and vomiting 15%, alopecia 30%, stomatitis 10%. These toxicities were tolerable and reversible. CONCLUSION: VIP regimen was not superior to previous regimens for advanced non-small all lung cancer, and the toxicities were tolerable.

There is increasing evidence that inactivation of tumor-suppressor genes can promote tumor growth. Retinoblastoma protein (pRb) is the product of the retinoblastoma gene located on chromosome 13q14. pRb negatively regulates cell growth when functioning normally. Mutational inactivation of the Rb gene has been observed in retinoblastomas, osteosarcomas and soft tissue sarcomas. Recently, several other human cancers have also been shown to carry abnormalities of the Rb gene. The potential role of the Rb gene in cutaneous squamous cell carcinomas (SCCs) and basal cell caicinomas (BCCs), has not been determined and was the focus of this study. Immunohistochemical expression of pRb in 16 cutaneous SCCs and 17 BCCs was examined. The expression of PCNA was studied in parallel to assess the cellular proliferation rate in these lesions. The pRb and PCNA immunoreactivity were localized to the nuclei of tumor cells. A few pRb and PCNA positive cells were seen in normal squamous epithelium, sebaceous glands, sweat glands and hair follicles. The loss of expression of pRb was seen in 3 of 16 SCCs(18.8%) and 6 of 17 BCCs (35.3%). PCNA immunoreactivity was slightly high in pRb-negative or lower-positive cases. PCNA immunoreactivity was similar to that produced by pRb in some cases. These results suggest that mutational inactivation of the Rb gene may be related to the carcinogenesis of cutaneous SCC and BCC, though the frequency is relatively low.

PURPOSE: In gastric cancer, metastasis to the paraaortic lymph nodes had been regarded as an incurable factor, but many cases of long term survival have been reported with dissection of metastatic paraaortic nodes. And several reports suggested survival benefit with paraaortic lymph node dissection (D4) in advanced gastric cancer. In patients with advanced gastric cancer who underwent paraaortic lymph node dissection we tried to evaluate the factors predisposing metastasis in these nodes and survival data. MATERIALS AND METHODS: The authors analyzed retrospectively pathological features of 95 patients who underwent paraacntic lymph node dissection for advanced gastric cancer at Kangnam General Hospital Public Corporation Bom May 1991 to Feb. 1998. And we also analysed survival results of 72 cases among them. We excluded 18 cases of distant metastasis (3 liver metastasis, 15 peritoneal seeding), 2 operative mortalities, 1 other disease mortality, and 2 unlmown causes of death in survival analysis. RESULTS: The frequencies of paraaortic lymph node metastasis were 0.0% (0 of 32 cases) in T2, 19.2% (10 of 52 cases) in T3, 18.2% (2 of 11 cases) in T4. And those of paraaortic lymph node metastasis were 5.8% (3 of 52 cases) in antrum, 14.3% (3 fo 21 cases) in body, 20.0% (3 of 15 cases) in cardia, and 42.9% (3 of 7 cases) in whole area. The five-year survival rates (5 YSRs) in relation to the paraaortic lymph node (No16) status was 0.096 in No16+, and 57.8Po in Nol6 with D4 of advanced gastric cancer. The 5 YSRs were 78.1%, 40.8% and 0% in T2, T3 and T4, respectively and 93.8%, 64.2%, 24.2% and 0.0% in n0, nl, n2 and n.3, respectively and 88.9%, 80.5%, 57.9% and 0.0% (47.6%) and 0.0% in stage IB, II, IIIA, IIIB and IV, respectively. CONCLUSION: The depth of gastric wall invasion and the location of primary tumor were significant predisposing factors to para-aortic lymph node metastasis in multivariate analysis (p<0.05). Survival of No16 metastasis was very poor. And three factors of T stage, n stage, and Bonmann type were also prognostically significant in terms of five year survival in cases of D4 of advanced gastric cancer in multivariate analysis (p < 0.05).

Facial clefts are uncommon congenital deformities in comparison to the clefts of the lip and palate. the clinical expression of the craniofacial clefts is highly variable. the face can be marred by a faint expression of the cleft or be disfigured by a full representation of the defect. the extent of the soft tissue and skeletal components is also variable, and they are seldom affected to an equal degree. Generally, discription of the clefts are based on the bony malformation, since the skeletal landmarks tend to be more constant. I report six cases of rare craniofacial clefts that I recently experienced. the soft tissue repair was accomplished with local flaps from cheek, eyelid and nose. Additional vertical length was obtained from the lower Z-plasty flaps in the sutures. the coloboma was corrected with local flaps and a cartilage graft, the depression of cheek with a dermofat graft, and the macrostomia with the repositioning of orbicularls oris muscle and a Z-plasty. the results were cosmetically acceptable.
