  • One of the major problems of cancer chemotheraphy is the development of drug resistance in tumors, resulting in reduced responsiveness to subsequent treatments. The folate antagonists are being used to treat such diverse illnesses as cancer, leukemia, psoriasis, rheumatoid arthritis, etc. Previous studies have established that resistance to antifolates may occur in mammalian tumor cells by one or more of five mechanisms ; (a) an increase in the levels of the target enzyme, generally as a consequence of gene amplification ; (b) an alteration in the target enzyme, leading to an enzyme with a decreased binding affinity for the drug ; (c) a decrease in the uptake of the drug into the cells ; (d) increased extrusion of drugs out of cells ; (e) impaired ability to polyglutamylate the parent drug which is capable of being intracellularly metabolized to longer chain length.

  • Purpose: In this study, the effects of laughter therapy on levels of depression, quality of life, resilience and immune responses in breast cancer survivors were examined. Methods: A quasi-experimental nonequivalent control group, pretest-posttest design was used. Participants (n=37) included breast cancer survivors who finished chemotheraphy and radiation therapy: 16 in the experiment group and 21 in the control group. Data were collected from August to November 2009. The experimental group participated in laughter therapy eight times, twice a week for 60 min per session. Questionnaires were used to me-asure pretest and posttest levels of depression, quality of life and resilience. A blood test was used to analyze changes in Total T cell, T helper, T suppressor, Th/Ts ratio, Total B cell, T cell/B cell ratio and NK cell for immune responses. Results: The results showed that laughter therapy was effective in increasing the quality of life and resilience in breast cancer survivors. but depression and immune responses did not differ significantly between the groups. Conclusion: The results of the study indicate that laughter therapy may be an effective nursing intervention to improve quality of life and resilience in breast cancer survivors.

  • Objective: To investigate the efficacy and safety of Yadanzi$^{(R)}$ (Javanica oil emulsion injection) combined with chemotherapy for treatment of patients with advanced gastric cancer. Methods: From January 2011 to December 2012, we recruited 75 patients with advanced gastric cancer, who received javanica oil emulsion injection together with chemotherapy. After two cycles of treatment, efficacy and safety of the combined therapies were evaluated. Results: Overall response rate of 75 patients after treatment was 85.3% (CR+PR+SD). Treatment related side effects were recorded. No treatment related death occurred. Conclusions: Javanica oil emulsion injection combined with chemotherapy could be considered as a safe and effective regimen in treating patients with advanced gastric cancer. Further randomized clinical trials should be conducted to confirm whether the addition of Yadanzi$^{(R)}$ to chemotheraphy could be associated with reduced toxicity, enhanced tolerability and improved quality of life for patients with advanced gastric cancer.

  • A literature study on oncological immune therapy was done, and the results were as follows. 1. Oncological immune therapy is classified as specific non specific therapy or active inactive therapy, and in tumor immune response, cellular immunity operates mainly, so activity of T lymphocytes and macrophages are closely related with growth, progress, metastasis and prospect of tumor. Recently, Immune therapies of gene which use cytokines and HLA-B7 are carrying out. 2. In oriental medicine, development of disease is closely related to up and down of healthy qi, so healthy qi operates as a immune factor and resistance factor. 3. On the base of theory "Increasing healthy qi reduces mass(養正則積自除)", strengthening body resistance is emphasized in cancer therapy. Also strengthening body resistance activates cellular immune response and promote killing tumor facility of T-cell. 4. In clinical view, using immune therapy after operation, radiation, and chemotheraphy is more effective than immune therapy itself, so it is expected that east-west cooperation will be effective in cancer therapy. 5. The study of oncological immunity is progressed on emphasizing T-cell and it is related to oriental medical theory "strengthening healthy qi to eliminate pathogen(扶定祛邪)" and advanced study is expected in future.

  • Objective: To observe the efficacy and toxicity of nanoparticle albumin bound paclitaxel (nab-paclitaxel) plus platinum agent (cisplatin or carboplatin) as first line treatment for stage III/IV squamous non-small-cell lung cancer (NSCLC). Methods: Forty chemotherapy naive patients with stage III/IV squamous NSCLC received nab-paclitaxel $125mg/m^2$ on day 1 and day 8, cisplatin $75mg/m^2$ on day 1, carboplatin area under the concentration-time curve of 5 (AUC=5) on day 1. One cycle of treatment was 3 weeks, and at least two were completed in each case. Results: Of the 40 patients who participated in the study, 25 achieved partial responses (PR), 12 reached a stage of stable disease (SD), and 3 suffered progressive disease (PD). The overall response rate (ORR) was 62.5% and the disease control rate (DCR) was 92.5%. Of the 20 patients without surgery or radiotherapy, 10 achieved PR, 7 reached a stage of SD, and 3 PD. The ORR was 50.0% and the DCR was 85.0%. The median progression-free survival time (PFS) of patients without surgery or radiotherapy was 5.0 months. Of the 20 patients receiving surgery or radiotherapy, 15 had PR and 5 p had SD, with an ORR of 75.0% and a DCR of 85.0%. Specifically, the DDP arm demonstrated a significantly higher ORR than the CBP arm (100%vs 54.5%, P<0.05). Common treatment related adverse events were myelosuppression, gastrointestinal response, baldness and neurotoxicity, most of which were grade 1 to 2. Conclusion: Nab-paclitaxel plus platinum agent (cisplatin or carboplatin) is effective as a first-line chemotheraphy for stage III/IV squamous NSCLC, and its adverse effects are tolerable.

  • Chlorogenic acid and hydroxylcinnamoyl shikimates are major dietary phenolics as well as antioxidants, with recently discovered biological, activities including protection against chemotheraphy side effects and prevention of cardiovascular disease and cancer. Certain fruits and vegetables produce these compounds, although a microbial system can also be utilized for synthesis of chlorogenic acid and hydroxylcinnamoyl shikimates. In this study, we engineered Escherichia coli to produce chlorogenic acid and p-coumaroyl shikimates from glucose. For the synthesis of chlorogenic acid, two E. coli strains were used; one strain for the synthesis of caffeic acid from glucose and the other strain for the synthesis of chlorogenic acid from caffeic acid and quinic acid. The final yield of chlorogenic acid using this approach was approximately 78 mg/l. To synthesize p-coumaroyl shikimates, wild-type E. coli as well as several mutants were tested. Mutant E. coli carrying deletions in three genes (tyrR, pheA, and aroL) produced 236 mg/l of p-coumaroyl shikimates.

  • Background and Objectives : Panax ginseng C.A. Meyer is a medical plant that has been widely utilized as a tonic and nutritional agent since ancient times in Korea. Ginseng has anti-metastatic property of cancer and immunomodulating activity. The novel acidic polysaccharide compound(MB40) was isolated from the leaves of Panax ginseng C.A. Meyer. To determine immunomodulating activities of MB40, we evaluate anti-cancer and anti-metastatic effects of MB40 in tumor bearing immune competent mice. Material and Methods : C3H mice were divided into three equal groups(Cisplatin treatment group, MB40 treat-ment group, Cisplatin and MB40 treatment group) and were transplanted SCC(Squamous Cell Carcinoma) cells(2${\times}$106) to the lateral side of abdomen. From day 4 after transplantation, MB40 was administrated at dose of 10mg/kg, respectively, every other day by intratumoral injection. Cisplatin was systemically administrated at doses of 1mg/kg, respectively, every week by intraperitoneal injection. Results : 5 days after administration, tumors can be palpated in every mice group. After 13 days of administration, the mice group to which MB40 were administrated exhibited reduction in tumor size respectively, compared to cisplatin group. Overall status of mice such as body weight and activity were superior in MB40 group than cisplatin group. Conclusion : The result of this study indicates MB40 may have significant therapeutic effect and decreases complications induced by systemic chemotheraphy. MB40 may be developed as a novel and potent immunotropics to improve the cell immune system and anti-cancer drug for the treatment of cancer patients in head and neck squamous cell carcinoma.

  • Purpose: The incidence rate and the mortality rate of gastric cancer have decreased in developed countries over the last several decades. On the other hand, they remain high in far eastern countries such as Korea, Japan, China and in many developing countries. The cure of patients with gastric carcinomas can be achieved mostly through complete surgical resection, but most gastric cancer patients are in advanced stages when diagnosed and have poor prognoses. therefore, the development of an effective systemic therapy is essential for far advanced gastric cancer patients. Until recently, the most commonly used combination chemotherapy was based on 5-flurouracil or cisplatin, but the results were not satisfactory, so recently etoposide, adriamycin and cisplatin (EAP-II) combination chemotherapy was introduced in patients with advanced gastric cancer. Early studies showed a high response rate and the ability to convert unresectable cases to resectable ones, but later studies couldn't duplicate the result. the purpose of this study was to evaluate the relative efficacy & toxicity of EAP-II chemotherapy and ELF chemotherapy which is based on 5-flurouracil. Materials and Methods: Between July 1992 and July 2002, sixty-five patients with inoperable advanced gastric cancer were enrolled for this study. Thirty-seven patient received EAP-II chemotherapy:etoposide (20 mg/$m^{2}$ IV for $1\∼5 days$), adriamycin (20 mg/$m^{2}$ IV for $1\∼5 days$) and cisplatin (20 mg/$m^{2}$ IV for $1\∼5 days$) and Twenty-eight patients receieved ELF chemotherapy : etoposide (100 mg/$m^{2}$ IV for $1\∼3 days$), leucovorin (20 mg/$m^{2}$ IV for $1\∼5 days$) and 5-FU (500 mg/$m^{2}$ IV for $1\∼5 days$). Each treatment schedule for each group was repeated every four weeks: EAP-II means 3.4 cycles per patient..ELF means 4.1 cycles per patient Results: Total respones rates were $5.4\%$ in the ELF group and $3.6\%$ in the EAP group (P-value>0.05). The median times to progression were 144 days in the ELF group and 92 days in the EAP-II group (P-value<0.05), and themedian overall survival times were 189 days in the ELF group and 139 days in the EAP-II group (P-value>0.05). The difference in the survival curves for the two regimens was not statistically significant. Non-hematologic toxicitis & hematologic toxicitis were more frequently observed for the EAP-II regimen. Anemia: $27.6\%$ in ELF vs $54\%$ in EAP-II; Leukopenia: $8.5\%$ in ELF vs $19\%$ in EAP-II; nausea & vomiting: $45.9\%$ in ELF vs $67.8\%$ in EAP-II. Conclusion: EAP-II regimen is not superior to ELF regimen in the tratment of inoperable advanced gastric cancer (J Korean Gastric Cancer Assoc 2003;3:122-127)

  • Rhabdomyosarcoma is the most common soft tissue sarcoma in childhood and acounts for 6% to 15% of all cases of childhood cancer, Rhabdomyosarcoma in seventh most common form of childhood neoplasms, following acute leukemia, tumors of the central nervous system, lymphoma neuroblastoma, Wilm`s tumor, bone tumor. Rhabdomyosarcoma can arise anywhere in the body, but primary site in the thorax is relatively rare. We experienced a case of aveolar rhabdomyosarcoma arising from intercostal muscle, A 12 year-old woman was suffered from the intermittent left chest pain radiating to the scapular area and dyspnea, On physical examination, pulmonary friction rub was heard on the left upper lobe area. Qn adimission, the chest simple radiography revealed a 7 x 6, 5cm sized radio-opaque mass with pleural effusion in the superior mediastinum and the CT showed a well difined radio-opaque mass including the destructed 2nd rib and pleural effusion. The percutaneous tra-nsthoracic needle aspiration biopsy was likely to show blastoma. After the chemotherapy[vincristine, actinomycin-D, cyclophosphamde] was done to treat blastoma, the pleural effussion was subsided and the mass was slightly decreased by 4.5x 4. 5cm. For treatment and diagnosis, we performed en-bloc resection and the defected chest was reconstucted with Gortex patch. Grossly, the specimen was colored graysh-white and arised in between two ribs The microscopic findings showed that the tumor cells were small round with scant pinkish cytoplasm on the H-E stain and the tumor cell nests were grouped by reticulum fibers and showed alveolar pattern on the silver stain The electromicroscopic finding presented that the cytoplasm contained tangled fibrillar and flocculent materials. The histopathologic findings were compatable with laveolar rhabdomyosarcoma. She was discharged without any complication. After discharge, she has been treated with radiation theraphy and chemotheraphy, and not recurred untill last follow-up We report a case of alveolar rhabdomyosarcoma arising to intercostal muscle, developed in 12 year-old waman, with brief review of literatures.

  • 목적: 미슬토 추출물은 서양에서 오래전부터 사용되어진 면역치료 물질로 위암에 대해서는 연구가 부족한 실정이다. 본 연구에서 수술 받은 위암환자를 대상으로 항암제와 미슬토 추출물의 병합투여가 면역기능에 미치는 효과를 파악하기 위해 시행되었다. 대상 및 방법: 원발성 위암으로 진단받고 근치적 수술을 받은 10명의 환자를 선정하여 항암화학요법과 병행하여 수술 후 7일째부터 미슬토 추출물(ABNOVA viscum-Q)을 주 3회, 총 16주간 피하주사 하였다. 면역기능에 미치는 효과는 환자의 말초혈액에서 백혈구수와 그 분획, 백혈구에 대한 총림프구의 분율 그리고 시토카인들(Interleukin-$1{\beta}$, Interleukin-2, Interleukin-6, Interferon-$\gamma$, Tumor necrosis factor-$\alpha$)의 변화를 분석하였다. 상기 항목들은 수술 전과 수술 후 8주, 16주 총 3회 측정되었다. 결과: 남녀비는 9 : 1이며, 평균연령은 55.9세(range $33{\sim}74$세)였다. 병기는 stage Ib가 4명, II가 6명이었다. 백혈구수와 총호중구수는 기저치에 비해 치료 후 8주와 16주에 유의한 감소를 보였다. 총호산구수는 기저치에 비해 8주와 16주에 증가하는 경향을 보였지만 통계적 유의성은 없었다(P=0.15). 총림프구의 수치는 치료 전후 유의한 감소를 보이지만 백혈구 수에 대한 총 림프구의 분율은 유의하지는 않지만(P=0.91) 오히려 증가하고 있다. 각각의 시토카인들은 치료전후 큰 변화를 보이지 않았다. 결론: 치료 전후 의미있는 면역반응의 증가는 관찰하기 어려웠다. 이것은 미슬토 추출물과 항암제의 병용투여에 의한 면역활성과 억제의 상쇄반응으로 생각된다. 총호산구수가 증가하였고, 백혈구에 대한 림프구의 분율이 감소하지 않고 증가하는 양상을 보인 것은 미슬토 추출물에 의해 유발된 면역반응으로 생각된다.
