A total of 47 patients with a diagnosis of nasopharyngeal carcinoma was treated in Department of Therapeutic Radiology, Seoul National University Hospital during last 4 years. Of the 47 patients, 23(49%) had undifferentiated carcinoma, 20(43%) had squamous cell carcinoma, while 4(8%) had lymphoepithelioma. Most of the patients(71%) has Stage IV disease, cervical lymph node metastases were found in 36(77%) and distant metastasis was found in 1 at the time of diagnosis. Complete response rate after radiotherapy for 47 patients of nasopharyngeal carcinoma was 85.1%. The overall actuarial 3 year survival rates was 0.718 and the disease free actuarial 3 year survival rates was 0.468. Nodal involvement and symptom duration were statistically significiant influencing factors for actuarial survival rate. Treatment failures were found in 20 patients (42.6%), local recurrence only in 6(30%), local and neck recurrence in 3(15%), local recurrence with metastasis in 4(20%) and distant metastasis only in 7(35%). Local failures were more frequent in the patients with cranial nerve symptoms (P=0.032). Distant metastases were more frequent with T4 lesions (P=0.047), and with nodal involvement (P<0.01). Retreatment after the tumor recurrence was chemotherapy and/or radiotherapy, two patients refreated for local recurrence were alive without evidence of disease for more than 19 and 44 months after retreatment.

PURPOSE: Osteopontin (OPN) binds to CD44 and nuclear factor-kappaB (NFkappaB) and OPN mediates tumorigenesis, invasion and metastasis, but the interrelationships between OPN, CD44 and NFkappaB are not fully understood, and especially in gastric carcinogenesis. We examined the expressions of OPN, CD44, and NFkappaB in untreated gastric adenocarcinomas. MATERIALS AND METHODS: The materials from 211 cases of gastric adenocarcinoma were immunostained for OPN, CD44 and NFkappaB by using a tissue microarray. The OPN mRNA expression was measured in 10 cases by performing real-time RT-PCR. RESULTS: The expression of OPN, CD44 and NFkappaB was noted in 61.7%, 11.4% and 26.6% of the adenocarcinoma tissues, respectively. No significant correlation was detected among the expressions of these proteins. The OPN protein expression was negatively correlated with angioinvasion (p<0.05) and patient survival (p<0.05), whereas the CD44 and NFkappaB protein expressions were not correlated with any of the clinicopathological factors we examined. The depth of invasion, lymph node status and perineural invasions were prognostic factors based on the Cox analysis. The OPN mRNA expression showed no significant difference between the adenocarcinoma and the paired normal mucosa on real-time RT-PCR. CONCLUSION: OPN may have a currently undetermined role in gastric carcinogenesis, and CD44 and NFkappaB may have minor roles in gastric adenocarcinoma.

PURPOSE: We wanted to demonstrate the anti-cancer effect and interaction between belotecan and cisplatin on gastric cancer cell line and we evaluated the mechanisms of this synergistic effect in vitro. MATERIALS AND METHODS: The growth inhibitory effect of belotocan and cisplatin against several gastric cancer cell lines (SNU-5, SNU-16 and SNU-601) was estimated by tetrazolium dye assay. The effect of a combination treatment was evaluated by the isobologram method. The biochemical mechanisms for the interaction between the drugs were analyzed by measuring the formation of DNA interstrand cross-links (ICLs) and DNA topo-I activity. RESULTS: Belotecan showed synergism with cisplatin for growth inhibitory effect on the gastric cancer cell lines SNU-5, and SNU-16, but this was subadditive on the SNU-601 cell line. The formation of DNA ICLs in SNU-16 cells by cisplatin was increased by combination with belotecan, but this was not affected in SNU-601 cells. The topo-I inhibition by belotecan was enhanced at high concentrations of cisplatin in SNU-16, but not in SNU-601 cells. CONCLUSION: Belotecan and cisplatin show various combination effect against gastric cancer cells. The synergism between cisplatin and belotecan could be the result of one of the following mechanisms: the modulating effect of belotecan on the repair of cisplatin-induced DNA adducts and the enhancing effect of cisplatin on the belotecan-induced topo-I inhibitory effect.

BACKGROUND: Because of the relative paucity of data regarding the clinical outcome in adult patients with acute lymphocytic leukemia (ALL) in Korea, we analyzed clinical courses in adult ALL patients treated with VPD (L) regimen (vincristine, prednisolone, daunorubicin, L-asparaginase) at the Seoul National University Hospital, and evaluated prognostic factors influencing the outcome. METHODS: Patients with ALL newly diagnosed between October 1994 and June 2000 at our hospital were analyzed retrospectively. Fifty-three patients were evaluable. Induction chemotherapy consisted of VPD with (46 cases) or without L-asparaginase (7 cases). After complete remission (CR), consolidation therapy, CNS prophylaxis and maintenance chemotherapy were administered. RESULTS: Ages ranged from 16 to 67 (median 30). CR rate was 86.8% (46/53) and no significant prognostic factor was found for the CR rate. With a median follow-up time of 27.2 months (range 12.9~83.0 months) in living patients, the median overall survival (OS) for all cases was 16.7 months (13.4~20.1 months, 95% C.I.) and the estimated 4-year OS rate was 25.4%+/-8.9%. The median relapse-free survival (RFS) was 12.2 months (8.4~16.0 months, 95% C.I.), and 3-year RFS rate was 29.9%+/-10.2%. Poor prognostic factors for OS were Ph chromosome (p=0.005) and T-cell immunophenotype (p=0.03). For RFS they were Ph chromosome (p=0.01) and the presence of a mediastinal mass (p=0.03). CONCLUSION: Despite an initial excellent response to the VPD (L) regimen, newer therapeutic strategies, including more intensive postremission therapies, are urgently needed because of the high relapse rate. Future therapeutic approaches need to be stratified according to several prognostic factors.
