PURPOSE: This study was performed to analyze the efficacy of induction chemotherapy followed by radiation therapy in locally advanced non-small cell lung cancer. MATERIALS AND METHODS: Eighty patients with locally advanced non-small cell lung cancer treated from 1989 to 1995 at Pusan Paik hospital were analyzed retrospectively. Twenty-one patients were treated with induction chemotherapy followed by radiation therapy and Fifty-nine patients were treated with radiation therapy alone. Chemotherapy regimen consisted of cisplatin-based combination (2 or 3 drugs). All patients were treated by Co-60 or 6 MV linear accelerators. Radiation dose ranged from 50 Gy to 80 Gy (median, 64.8 Gy). We evaluated response rate, survival rate, and pattern of failure in both treatment groups. RESULTS: Overall response rate in induction chemotherapy group and radiotherapy alone group were 48% and 45%, respectively. Of the 80 patients, 46 patients were evaluable for pattern of failure. Initial failure pattern in induction chemotherapy group was as follows: 8 (67%) at locoregional, 4 (33) in distant metastasis. Radiation alone group was 21 (71%) and 5 (29%), respectively. Results showed no difference of distant failure between induction chemotherapy group and radiation alone group. The 1 and 2 year survival rate in induction chemotherapy group were 43% and 14%, respectively and in radiotherapy alone group, 31% and 7%, respectively (p=0.135). CONCLUSION: In stage lll non-small cell lung cancer, induction chemotherapy and radiation therapy showed increased tendency in survival with no statistical significance. Induction chemotherapy seems to have no effect of decreasing distant failure and no survival advantage compared with radiotherapy alone.

PURPOSE: A retrospective study was performed o define the clninical significance of p53, P-glycoprotein (Pgp), and Glutathione S transferase-pi (GST-pi) immunohistochemical (IHC) expression in advanced non-small cell lung cancer (NSCLC). MATERIALS AND METHODS: We reviewed fifty seven patients with advanced NSCLC who had undergone surgical resection or bronchoscopic biopsy between March 1997 and March 1999. IHC staining for p53, GST-pi, and Pgp was performed using formalin-fixed, paraffin-embedded specimens of the fifty seven patients. RESULTS: The IHC expression rate was 63% for p53, 28% for Pgp, and 53% for GST-pi, respectively. The median survival of the fifty seven patients was 45 weeks and the response rate was 38.6% (partial response, 22/57). The chemotherapy response and median survival of the p53 negative group (57% and 61 weeks) were better than those demonstrated by the p53 positive group (28% and 21 weeks) (p<0.05). Additionally, the GST-pi negative group showed a greater improvement of survival and response rate than the positive group (p<0.05). Pgp expression status appeared to have no significant differential effect on chemotherapy response and survival. CONCLUSION: These results suggest that immunohisto chemical staining of p53 and GST-pi may be useful in predicting the response to chemotherapy as well as survival in advanced NSCLC. However, this study is limited by its retrospective nature and the small numbers of tumors studied from a heterogenous group of patients.

PURPOSE: We evaluated three blood glucose self-monitoring for measuring whole blood glucose levels in preterm and low-birth-weight infants. METHODS: Between December 1, 2012 and March 31, 2013, 230 blood samples were collected from 50 newborns, who weighed, < or =2,300 g or were < or =36 weeks old, in the the neonatal intensive care unit of Eulji University Hospital. Three blood glucose self-monitoring (A: Precision Pcx, Abbott; B: One-Touch Verio, Johnson & Johnson; C: LifeScan SureStep Flexx, Johnson & Johnson) were used for the blood glucose measurements. The results were compared to those obtained using laboratory equipment (D: Advia chemical analyzer, Siemens Healthcare Diagnostics Inc.). RESULTS: The correlation coefficients between laboratory equipment and the three blood glucose self-monitoring (A, B, and C) were found to be 0.888, 0.884, and 0.900, respectively. For glucose levels< or =60 mg/dL, the correlation coefficients were 0.674, 0.687, and 0.679, respectively. For glucose levels>60 mg/dL, the correlation coefficients were 0.822, 0.819, and 0.839, respectively. All correlation coefficients were statistically significant. And the values from the blood glucose self-monitoring were not significantly different from the value of the laboratory equipment , after correcting for each device's average value (P>0.05). When using laboratory equipment (blood glucose < or =60 mg/dL), each device had a sensitivity of 0.458, 0.604, and 0.688 and a specificity of 0.995, 0.989, and 0.989, respectively. CONCLUSION: Significant difference is not found between three blood glucose self-monitoring and laboratory equipment. But correlation between the measured values from blood glucose self-monitoring and laboratory equipment is lower in preterm or low-birth-weight infants than adults.

BACKGROUND: The CHOP regimen has been the standard therapy for non-Hodgkin's lymphoma (NHL) for the past 30 years, but its effect on complete response and long-term survival rates were unsatisfactory. Therefore, more effective chemotherapeutic regimens are required. We attempted to treat non-Hodgkin's lymphoma with a newly developed cyclophosphamide, adriamycin, etoposide, prednisolone (CHEP) combination chemotherapy which substitutes etoposide for vincristine in a preexisting cyclophosphamide, adriamycin, prednisolone, vincristine (CHOP) regimen. METHODS: Between March 1997 and April 2003, 36 patients with a histologically confirmed NHL were enrolled in the study. All patients received CHEP chemotherapy as a first-line treatment. Tratment courses were repeated every 34 weeks for at least 4 cycles, pending response to the treatment. RESULTS: The overall response rate achieved was 86.1% for all of the patients. The complete response (CR) and partial response (PR) rates were 72.2% and 13.9%, respectively. The CR rate was significantly higher in patients with stage III disease, and a PS score of 02 (p<0.0001, p=0.017, respectively). The three year overall (OS) and failure-free survival (FFS) rates were 61.2%, 58.2%, respectively. Stage, extranodal involvement, and the attainment of CR influenced OS significantly (p=0.027, p=0.047, p=0.0001, respectively) as determined by univariate analysis. Stage, serum LDH level, extranodal involvement, the international prognostic index (IPI), and the attainment of CR influenced FFS significantly (p=0.0013, p=0.048, p=0.020, p=0.018, p=0.0001, respectively) as determined by univariate analysis. The dose-limiting toxicity was due to myelosuppression. Nno neurologic side effects were seen, which frequently occur after using vincristine. CONCLUSIONS: The CHEP regimen in patients with aggressive NHL is effective as a first-line therapy, and possesses an acceptable toxicity profile. We suggest a trial that adds rituximab to the CHEP regimen as afirst-line therapy for aggressive NHL in the future.

PURPOSE: Although there is an increasing incidence of upper third gastric cancers, the appropriate extent of resection for upper third gastric cancer is not known. This study was performed to analyze a 9-year experience with upper third gastric adenocarcinomas from one institution treated by either total gastrectomy (TG) or proximal gastrectomy (PG). METHODS: The records and survival data of 158 upper third gastric cancer patients who underwent curative TG (n=106) or PG (n=52) through an exclusively abdominal approach were retrospectively analyzed. RESULTS: There was no significant difference in age, sex, tumor gross type, tumor differentiation, and stage between the groups who underwent TG and those who underwent PG. In addition, there were no significant differences in hospital mortality, overall 5-year survival, and disease-free survival rates between PG and TG group. However, PG group showed higher rates of postoperative reflux esophagitis and anastomosis stricture than TG group. Regarding the main patterns of recurrence, local recurrence was dominant in PG group, whereas distant recurrence was dominant in TG group. CONCLUSION: The extent of resection for upper third gastric cancer does not affect long-term outcome, and both procedures can be accomplished safely. When the cancer is confined to upper third of the stomach without serosal invasion, PG combined with antireflux procedures can be indicated.
