Thirty-one patients with previously untreated and locally advanced nasopharyngeal cancer were retrospectively reviewed for comparing the effects of radical radiotherapy alone with that of combining chemotherapy and radiotherapy from 1983 to 1989 at Kangnam 51. Mavy's hospital.23/31 were evaluable for recurrence and suwival. There were 8 patients for stage III, and 15 patients for stage IV. Eleven patients were treated with radical radiation therapy done (arm I). Twelve patients were given 1~3 courses of cisplatin-5FU or cisplatin-bleomycin-vincristine prior to radiation therapy (arm II). The two arms were comparable in patient characteristics Of 11 radiotherapy Patients, complete response was 55%(6/11) and Partial response 45%(5/11). Among 12 patients after induction chemotherapy, complete response was 25%(3/12) and partial response 75%(9/12). After subsequent radiotherapy, complete response was increased to 83%(10/12) and partial response was 17%(2/12). Treatment failure was 30%(local recurrence; 3/11, and regional recurrence; 1/11) in arm 1 and 33% (local recurrence; 1/12, regional recurrence; 2/12 and distant metastasis; 1/12) in arm ll . There was no significant difference in survival between arm I and arm II (p> 0.05). The toxicities of treatment were acceptable. More controlled clinical trials must be completed before acceptance of chemotherapy as part of a standard radical treatment for locally advanced nasopharyngeal cancer.

The prognosis of gastric cancer with hepatic metastasis is very poor, even though several treatment modalities exist, such as surgical resection. Indeed, a standard therapy has not been established in such patients. Recently, attempts were made to treat hepatic metastasis of gastric cancer with radiofrequency (RF), which was originally used in primary or metastatic liver cancer. RF has been reported to show similar survival compared to surgical resection and is emerging as a new treatment modality even though it is still not conclusive with respect to efficacy and safety due to the paucity of reports. A prospective study is warranted to evaluate the efficacy of RF in the treatment of gastric cancer with hepatic metastasis compared with conventional modalities.

Personal Health Record(PHR) service can be helpful to patients with diseases requiring strict everyday care and medical treatment, such as diabetes or cancer. In this paper, we propose a PHR system specialized in collecting and analyzing health record data of cancer patients, and present the process of how the system can improve the efficiency of cancer treatment process. Through the smart device application, cancer PHR system obtains daily PHR data which is highly related and critical to cancer therapy. The analysis report is provided to the medical staff with an available format suited for Electronic Medical Record used at medical institution. With the final result of PHR analysis which is easily merged with medical chart, most efficient Chemotherapy treatment can be provided for the patients. Also it is possible for the patients to give the information of side-effect and other pain experience during therapy to their doctors without loss of information. The proposed PHR system has the effect of improving the quality of patient care by allowing the medical staff to acquire the main objective data necessary for drug prescription and medical care benefits.

Purpose: Mistletoe extract was widely used for cancer treatment as complementary or alternative therapy in European area from early twenty century. It is currently used as alternative anti-cancer remedy by piecemeal in domestic medical group, however, the anti-cancer mechanism of mistletoe extract was not known precisely until now. In this study the effect of mistletoe extract on gastric cancer was studied vis cell line experiments. Materials and Methods: The SNU719 gastric cancer cell line was used, and ABNOBAviscum-Q and ABNOBAviscum-F were treated to cells as mistletoe extract, or 5-FU and cisplatin were used with mistletoe extract. The cell viability and cell death rate were estimated by CCK-8 assay kit and lactate dehydrogenase (LDH) assay kit in each. Caspase 3 assay kit was used to measure caspase 3 activity. The protein expression amounts of Bcl2, p53, and PTEN were estimated through Western blot analysis. Results: The co-treatments of mistletoe extract Q/F and 5-FU/cisplatin decreased lesser cell viability than only mistletoe treat. Caspase 3 activity was increased 4~6 times in co-treatment of mistletoe extracts and 5-FU than control. Bcl2 protein expression was reduced by mistletoe extracts or anti-cancer drugs, further more, the co-treatment of mistletoe extracts and 5-FU/cisplatin diminished more the expression than only mistletoe treatment. Mistletoe extracts did not affect the protein expressions of p53 and PTEN. Conclusion: It was concluded that the anti-cancer mechanism of mistletoe extracts was made by caspase 3 activation and lowered Bcl2 expression, and this apoptosis inducing mechanism was independent to p53.

Purpose : To evaluate the correlation between serum methotrexate (MTX) peak levels and clinical outcome of osteosarcoma, as well as to determine the correlation of these levels with the histologic response and event-free survival (EFS). Methods : To maintain the homogeneity of the study population, we selected 52 patients with localized extremity osteosarcoma who had received two cycles of neoadjuvant chemotherapy consisting of high-dose (HD) MTX ($12g/m^2$), cisplatin ($100mg/m^2$), and doxorubicin ($60mg/m^2$). Results : Totally, 204 courses of HD MTX were administered. The serial MTX levels ($mean{\pm}SE$) at 4 h (peak), 24 h, 48 h, and 72 h were $1292.14{\pm}12.83{\mu}m$, $9.29{\pm}3.89{\mu}m$, $1.73{\pm}1.37{\mu}m$, and $0.58{\pm}0.44{\mu}m$, respectively. The peak MTX serum level was $1292.14{\pm}12.83{\mu}m$. Neither the continuous average MTX peak level nor the dichotomized MTX peak level was related to the histologic response. However, the patients with a high 24-h MTX level ($3.4{\mu}m$) had a poor histologic response (P=0.044). An inverse relationship was observed between MTX levels and survival: the EFS was better in the patients with a mean MTX peak level of less than $1,400{\mu}m$ (P=0.002) and mean 24-h MTX level of less than $3.4{\mu}m$ (P=0.011). Conclusion : The inverse correlation between the MTX level and the outcome is an unexpected finding. Further study on the pharmacokinetics of MTX is required to substantiate our findings and elucidate the mechanism involved.

The sprig of Jinryungtang Gagambang has been used for curing as a traditional medicine without any experimental evidence to support the rational basis for their clinical use. This experiment was carried out to evaluate the possible therapeutic or antitumoral effects of Jinryungtang Gagambang extract against cancer, and to study some mechanisms responsible for its effect. The cytotoxic and antitumor effects were evaluated on human cell liens (A549, hep3B, Caki-1, Sarcoma 180) after exposure to Jinryungtang Gagambang extract using in ILS, colony forming efficency and SRB assay which were regarded as a valuable method for cytotoxic and antitumor effects of unknown compound on tumor cell lines. The results obtained in this studies were as follows. 1. As a result of exposure to Jinryungtang Gagambang extract, the proliferation of A549, hep3B, Caki-1, good correlations were shown from the results of SRB assay and those of clogenetic assay. 2. The oral administration of Jinryungtang Gagambang extract showed significant effects of increase of MST(mean survival time) and ILS(increased life span) depending on the increasing concentration. 3. Against squamous cell carcinoma induced by MCA, Jinryungtang Gagambang decreased not only the frequency of tumor production but also the number and weight of tumors per tumor bearing mice(TBM). Jinryungtang Gagambang also significantly suppressed the development of 3LL cell-implanted tumors by frequency and their size, and some developed tumors were regressed by the continuous treatment of Jinryungtang Gagambang extract into TBM. 4. Jinryungtang Gagambang extract also increased NK cell activities. According to the above results, it could be suggested that Jinryungtang Gagambang extract has prominent antiutmor effect.

[ $\underline{Purpose}$ ]: For the first time, a nationwide survey in the Republic of Korea was conducted to determine the basic parameters for the treatment of esophageal cancer and to offer a solid cooperative system for the Korean Pattern of Care Study database. $\underline{Materials\;and\;Methods}$: During $1998{\sim}1999$, biopsy-confirmed 246 esophageal cancer patients that received radiotherapy were enrolled from 23 different institutions in South Korea. Random sampling was based on power allocation method. Patient parameters and specific information regarding tumor characteristics and treatment methods were collected and registered through the web based PCS system. The data was analyzed by the use of the Chi-squared test. $\underline{Results}$: The median age of the collected patients was 62 years. The male to female ratio was about 91 to 9 with an absolute male predominance. The performance status ranged from ECOG 0 to 1 in 82.5% of the patients. Diagnostic procedures included an esophagogram (228 patients, 92.7%), endoscopy (226 patients, 91.9%), and a chest CT scan (238 patients, 96.7%). Squamous cell carcinoma was diagnosed in 96.3% of the patients; mid-thoracic esophageal cancer was most prevalent (110 patients, 44.7%) and 135 patients presented with clinical stage III disease. Fifty seven patients received radiotherapy alone and 37 patients received surgery with adjuvant postoperative radiotherapy. Half of the patients (123 patients) received chemotherapy together with RT and 70 patients (56.9%) received it as concurrent chemoradiotherapy. The most frequently used chemotherapeutic agent was a combination of cisplatin and 5-FU. Most patients received radiotherapy either with 6 MV (116 patients, 47.2%) or with 10 MV photons (87 patients, 35.4%). Radiotherapy was delivered through a conventional AP-PA field for 206 patients (83.7%) without using a CT plan and the median delivered dose was 3,600 cGy. The median total dose of postoperative radiotherapy was 5,040 cGy while for the non-operative patients the median total dose was 5,970 cGy. Thirty-four patients received intraluminal brachytherapy with high dose rate Iridium-192. Brachytherapy was delivered with a median dose of 300 cGy in each fraction and was typically delivered $3{\sim}4\;times$. The most frequently encountered complication during the radiotherapy treatment was esophagitis in 155 patients (63.0%). $\underline{Conclusion}$: For the evaluation and treatment of esophageal cancer patients at radiation facilities in Korea, this study will provide guidelines and benchmark data for the solid cooperative systems of the Korean PCS. Although some differences were noted between institutions, there was no major difference in the treatment modalities and RT techniques.
