1983년에서 1989년까지 가톨릭의대 부속 성모병원 방사선치료실에서 비인강종양으로 확진되어 치료를 시행한 환자 31명중 치료가 불완전했던 환자 8명을 제외한 23명의 치료성적으로 후향조사 하였다. 이들 중 11명의 환자에 있어서는 방사선 단독요법을 시행하였으며, 12명의 환자에소는 cispiatin+5-fluorouracil 혹은 cisplatin-bleomycin-vincristine을 이용하여 1회 내지 3회에 걸친 유도 화학요법후 방사선치료를 시행하였다. 방사선 단독요법으로 치료된 11명의 환자에서 완전 관해율은 55%(6/11), 부분관해율은 45%(5/11)였다. 유도화학요법을 시행한 12명의 환자중 약물 치료후 완전관해율은 25%(3/12)였으며, 부분관해율은 75%(9/12)였고, 연속적으로 시행된 방사선 치료후에는 완전 관해율이 83%(10/12)로 증가되었으며, 부분 관해율은 17%(2/12)였다. 유도 항암요법에 부분관해를 보였던 환자중 stage 111 환자 1명과 stage IV 환자 6명이 추가 방사선 치료후 완전 관해를 보였다. 방사선 단독요법군에서는 4명에 국소재발이 발생했으며,-약물요법과 방사선치료를 병행했던 군에서는 국소재발 3명과 폐로의 원격전이가 1명에서 발생되었다. 방사선단독으로 치료한 환자군과 유도화학요법과 방사선 치료를 병행한 환자군에서의 생존율의 차이가 통계적으로 유의하지 않았다. $28.55{\pm}15$ and $M{\pm}SD=28.588{\pm}25.39$, p>0.05) 치료환자군의 수가 적은 이유로 통계분석 결과 큰 의의를 발견할 수 없었다.

氷복茸兌\ulcorner환자에서 발생하는 연하곤란은 보통 역류성 식도염, 감염성 식도염, 화학요법 및 백혈병의 직접적인 식도 침범에 의해 발생하지만 그중에서도 백혈병 환자의 화학요법의 결과로 발생하는 식도협착중 급성으로 발병하는 경우는 아주 드물다. 본원에서는 40세의 남자환자가 급성 골수성 백혈병으로 화학요법 받은지 1개월 이내에 발생한 급성 식도협착으로 수술위해 입원, 식도 절제술 및 위식도 문합술 과 유문부 성형술을 시행하였다. 병리 조직검사상 단핵구들의 점막 침착 및 점막하조직과 근육층을 침범하는 섬유화소견을 보이고 있다.

Background: Loss of function of the p53 gene is implicated in defective apoptotic responses of tumors to chemotherapy. Although the pro-apoptotic roles of eugenol and capsaicin have been amply reported, their dependence on p53 for apoptosis induction in gastric cancer cells is not well elucidated. The aim of the study was to elucidate the role of p53 in the induction of apoptosis by eugenol and capsaicin in a human gastric cancer cell line, AGS. Materials and Methods: AGS cells were incubated with or without various concentrations of capsaicin and eugenol for 12 hrs, in the presence and absence of p53 siRNA. Cell cycling, annexin V and expression of apoptosis related proteins Bax, Bcl-2 ratio, p21, cyt c-caspase-9 association, caspase-3 and caspase-8 were studied. Results: In the presence of p53, capsaicin was a more potent pro-apoptotic agent than eugenol. However, silencing of p53 significantly abrogated apoptosis induced by capsaicin but not that by eugenol. Western blot analysis of pro-apoptotic markers revealed that as opposed to capsaicin, eugenol could induce caspase-8 and caspase-3 even in the absence of p53. Conclusions: Unlike capsaicin, eugenol could induce apoptosis both in presence and absence of functional p53. Agents which can induce apoptosis irrespective of the cellular p53 status have immense scope for development as potential anticancer agents.

Human prostate cancer is the second most frequently diagnosed cancer worldwide, and its incidence rate continues to increase. Advanced prostate cancer is more difficult to treat than early forms due to its chemotherapy resistance. There is need for more effective agents that can inhibit the progression of advanced prostate cancer. Demethoxyfumitremorgin C (DMFTC) was isolated from the fermentation extract of the marine fungus Aspergillus fumigatus. Antiproliferative activity of DMFTC against human prostate cancer PC3 cells was examined through cell cycle analysis by flow cytometry, the fluorescent nuclear imaging analysis with propidium iodide (PI), and proteins expression related to cell cycle arrest and apoptosis were investigated via Western blotting. DMFTC inhibited PC3 cells growth through G1 phase cell cycle arrest and apoptosis induction. It activated the tumor suppressor p53 and the Cdk inhibitor p21, which regulate the cell progression into the G1 phase. Additionally, PI-positive late apoptotic non-viable cells were increased and the expression levels of the G1-positive downstream regulators cyclin D, cyclin E, Cdk2, and Cdk4 were decreased by DMFTC treatment. These results suggest that DMFTC induces G1 arrest and apoptosis induction through regulation of p53/p21-dependent cyclin-Cdk complexes, and it may be a useful therapeutic agent for the treatment of human advanced prostate cancer.

Introduction: We present a case of multiple myeloma with amyloidosis, which has features of peripheral neuropathy after induction chemotherapy before autologous peripheral blood stem cell transplantation, in a 56-year-old woman with Korean medicine. Case Presentation: For 17 days of hospitalization, the patient with complaints of numbness and a tingling sensation in the hands and feet was treated with acupuncture, herbal medicine. To reduce the symptoms, we provided Korean medicine treatments, including herbal medicine, acupuncture, and moxibustion. The Visual Analog Scale (VAS) was used to evaluate the results of the treatment. Until discharge, the VAS scores decreased for both hands and the foot tingling sensation. Conclusion: According to these results, Korean medicine treatment may be considered an effective treatment for tingling sensations in a patient with multiple myeloma with amyloidosis. Prospective studies are needed in the future to confirm and expand these findings.

Background: ALL is an irredeemable disease due to the resistance to treatment. There are several influences which are involved in such resistance to chemotherapy, including oxidative stress as a result of the generation of reactive oxygen species (ROS) and presence of hypodiploid cells. Cluster of differentiation 26 (CD26), also known as dipeptidyl peptidase-4, is a 110 kDa, multifunctional, membrane-bound glycoprotein. Aim and objectives: The aim of this study was to evaluate the clinical significance of serum CD26 in patients with acute lymphoblastic leukaemia patients in the post remission induction phase, as well as the relationship between CD26 activity and the oxidative stress status. Materials and Methods: CD26, total antioxidant status (TAS), total oxidant status (TOS), and oxidative stress index (OSI), in addition to activity of related enzymes myeloperoxidase, glutathione-s-transferase and xanthine oxidase, were analysed in sixty children with acute lymphoblastic leukaemia in the post remission induction phase. Results: The study showed significant elevation in CD26, TOS and OSI levels in patients with acute lymphoblastic leukaemia in the post remission induction phase in comparison to healthy control samples. In contrast, myeloperoxidase, glutathione-s-transferase and xanthine oxidase activities were decreased significantly. A significant correlation between CD26 concentration and some oxidative stress parameters was evident in ALL patients. Conclusions: Serum levels of CD26 appear to be useful as a new biomarker of oxidative stress in children with acute lymphoblastic leukaemia in the post remission induction phase, and levels of antioxidants must be regularly estimated during the treatment of children with ALL.

The anticlastogenic effect of N-acetylcysteine was tested in vivo in mouse bone-marrow micronucleus assay. The frequencies of micronuclei induced by adriamycin (5 mg/kg i.p.) in bonemarrow cells were decreased by the oral administration of N-acetylcysteine at 12 h before adriamycin injection. The observed suppressing effect was not a reflection of a delay in the formation of micronuclei by the cytotoxic effect of N-acetylcysteine. The anticlastogenic effects of SH compound including N-acetylcysteine, cysteine, cystine, S-carboxy methylcysteine and glutathione were also investigated by the multiple pretreatment. Each SH compound was administered orally every day for 5 days and adriamycin (5 mg/kg i.p.) was injected at 24h after the last dose of test compound. N-acetylcysteine and glutathione showed significantly the suppressive effect at dose of 10 and 25 mg/kg for N-acetylcysteine and at the dose of 25 mg/kg for glutathione. Our study suggests that N-acetylcysteine is capable of protecting the chromosomal damages in the normal cells during cancer chemotherapy by adriamycin, and may act as an anticlastogen against induction of micronuclei by superoxide generating agent such as adriamycin.

Acute lymphocytic leukemia(ALL) is a malignant disease of the bone marrow in which early lymphoid precursors proliferate and replace the normal hematopoietic cells of the marrow. Currently, only $20-30\%$ of adults with ALL are cured with standard chemotherapy regimens. It is very important risk factor whether to failure to achieve complete remission within 4 weeks or not. The relapse of leukemia is usually classified as hematologic and extramedullary relapse, and extramedullary leukemic infiltration is rarely observed in patients with ALL. In October 2004, a 23-year-old man presented with painless enlargement of both parotid glands. He was diagnosed as ALL(L2 subtype) one month ago, and he gained complete remission with induction chemotherapy. Fine needle aspiration cytology and bone marrow biopsy revealed extramedullary and hemtologic remission. To our knowledge this is the first report of extramedullary relapse in the parotid in ALL.
