Purpose: This study was intended to identify the patterns of fatigue and its related factors in patients with stomach cancer during chemotherapy. Methods: Thirty participants (24 males and 6 females) were recruited for this study which utilized a longitudinal and descriptive approach. The research instruments included the Revised Piper Fatigue Scale, Symptom Distress Scale, and Linear Analogue Self Assessment Scale. The participants received 5-FU and Adriamycin at the first week and 5-FU only at the second and third week. The instruments were measured six times in total. The data were analyzed using SPSS 17.0. Results: It was found that fatigue scores in patients with stomach cancer, receiving 5-FU and Adriamycin (FA) regimen, reached the highest level on the third day (F=9.37, p=.024) after the initial infusion, and decreased gradually afterward. The symptom and psychological distress scores illustrated very similar pattern. The concept of multidimensionality of fatigue in patients with stomach cancer was supported in this study, showing that all four dimensions of the scale were positively correlated. Conclusion: The results of this study provided useful information of patients with stomach cancer on fatigue and other related symptoms which they experienced during weekly scheduled chemotherapy with FA regimen.

Purpose : To evaluate the effect of postoperative adjuvant radiation therapy and chemotherapy on the survival, pattern of failure and complication for locally advanced rectal carcinoma Materials and Methods : From October 1992 to September 1995, twenty eight patients with rectal carcinoma were treated by postoperative adjuvant radiation therapy and chemotherapy Radiation therapy was delivered with 6MV and 15MV linear accelerator, 180c0y fractions 5 day per week. Total radiation doses were 5040cGy in $B_{2+3}$ and 5580cGy in $C_{2+3}$. Within 4 weeks after radical surgery. 5-FU$(400mg/m^2/day)\;and\;Leucovorin(20mg/m^2/day)$ were administered by intravenous injection for 4 days during the first and fifth week of radiation therapy. The median follow up was 19 months with a range 2 to 47 months. Results : The 2 year overall survival and disease free survival rates were $78.6\%\;and\;70.8\%$, respectively. The 2 year overall survival was $93.0\%\;in\;B_{2+3}$ and $76.2\%\;in\;C_{2+3}$(p=0.11) The 2 year disease free survival was $79.4\%\;in\;B_{2+3}\;and\;69.2\%\;in\;C_{2+3}(p=0.13)$. The overall failure rate was $21.42\%$(6/28) including $10.72\%$(3/28) locoregional recurrence, $3.62\%$(1/28) distant metastasis and $7.12\%$(2/28) locoregional recurrence with distant metastasis. The overall locoregional recurrence rate was $17.92\%$(5/28). The 2 year locoregional recurrence rates were $13.32\%(2/15)\;and\;23.12\%$(3/13) for respectively for $B_{2+3}\;and\;C_{2+3}$ The difference between the locoregional recurrence of $B_{2+3}\;and\;C_{2+3}$ patients was not significant(p=0.07). Complications developed in 13 patients$(46.42\%)$, including 8 dermatitis, 7 loose stool, 6 leukopenia, 4 tenesmus, 2 diarrhea. In Univariate analysis, there was no statistically significant factor except for tumor grade in locoregional recurrence, disease free survival and overall survival rate(p=0.04, 0.05, 0.04). Conclusion : This study sugges1s that postoperative adjuvant radiation therapy and chemotherapy is effective in patients with locally advanced rectal cancer. Therefore these results need to be confirmed with a long term follow-up and larger number of patients with the further clinical trials including prospective controlled studies.

Background : Some malignancies including lymphoma, head and neck cancer, and lung cancer are believed to be associated with the reactivation of tuberculosis (TB) because cyclic anti-cancer chemotherapy can induce the leukopenia or immunological deterioration. This report describes the clinical characteristics and treatment response of TB that developed during cyclic anti-cancer chemotherapy in patients with a solid tumor. Materials and Methods : From January 1 2000 to July 31 2004, patients with TB diagnosed microbiologically, pathologically, or clinically during anti-cancer chemotherapy in a tertiary hospital were enrolled, and their medical records were reviewed. Patients with the known risk factors for the reactivation of TB were excluded. Results : Twenty-two patients were enrolled and their mean age was 56.5 years (range 21-78). The male to female ratio was 3.4:1 and pulmonary TB was the main variant (20 patients, 90.9%). Gastric cancer (10 patients, 45.4%) and lymphoma (4 patients, 18.2%) were the leading underlying malignancies. The other malignancies included lung cancer, head and neck cancer, breast cancer, cervix cancer, and ovary cancer. Fifteen patients (68.2%) had a healed scar on a simple chest radiograph suggesting a previous TB infection. Among these patients, new TB lesions involved the same lobe or the ipsilateral pleura in 13 patients (87.6%). An isoniazid and rifampicin based regimen were started in all the subjects except for one patient with a hepatic dysfunction. The mean duration of medication was $9.9{\pm}2.4$ months and no adverse events resulting in a regimen change were observed. With the exception of 5 patients who died of the progression of the underlying malignancy, 70.6% (12/17) completed the anti-TB treatment. Conclusion : The clinical characteristics and response to anti-TB treatment for TB that developed during anticancer chemotherapy for a solid tumor were not different from those of patients who developed TB in the general population.

Background: Pulmonary complications in immunocompromised patients are often fatal. Empirical treatment is usually applied based on the clinical and radiological findings because of the risk of the aggressive diagnostic procedures such as open lung biopsy. However, recent advancements in operative procedures and perioperative management has decreased the procedure-related risks. We have prospectively analyzed the risks and benefits of the early application of open lung biopsy in such patients. Material and Method: Forty-two consecutive immunocompromised patients with critical pulmonary complications were included from June, 1996 to December, 1999. The definition of the immunocompromised is as those with chemotherapy and/or other modality for hematologic disorders, with usage of immunosuppressive drug after transplantation, with usage of steroid for more than 1 month, and with primary immunodeficiency disorders. The indication of open lung biopsy was those with no significant improvement after a week of aggressive application of empirical treatment or with rapidly aggressive process. The underlying disease included hematologic disorder(31 patients), post-transplantation(3 patients), chemotherapy for solid tumor(2 patients), and others(6 patients). Operations were done through thoracotomy(conventional or mini-) or VATS.

혈액 세포 형성 과정인 조혈 작용은 콜로니 자극인자 (Colony Stimulating Factor, CSF)라 불리는 몇 종류의 당 단백질에 의해 조절된다. 이들 자극인자 중, GM-CSF는 다계통에 작용하는 조절인자로서 과립구와 거식세포의 생성을 조절한다고 알려져 있다 한편 GM-CSF는 생체내에서 백혈구의 형성을 조절하는 인자이기 때문에 골수이식을 한 환자 및 화학요법이나 방사선 치료를 받는 암환자에게서 발생하는 백혈구의 감소현상을 완화시키는 역할을 한다. 혈액의 보조화와 관련하여 의학적 효능을 나타낼 것으로 간주되는 GM-CSF를 유전자 재조합 기술로 효모에서 발현, 정제하여 물리화학적 특성 및 역가를 측정하는 것이 이 연구의 기본목적이다.

Background: High-dose chemotherapy is increasingly employed in many refractory malignant diseases. This therapy has been reported to increase response rate and survival benefits but it is also associated with higher treatment-related morbidity and mortality. We evaluated clinical characteristics and course of the pulmonary toxicity following high-dose chemotherapy with peripheral blood stem cell transplantation. Methods: Ninety-seven patients who had received high-dose chemotherapy with peripheral blood stem cell transplantation were evaluated. Five patients who developed lung lesions which were not related to infection nor primary malignant disease underwent transbronchial lung biopsy. The patients' clinical characteristics, treatments, and prognosis were reviewed retrospectively. Results: Five patients(5.1%) developed idiopathic pneumonia syndrome. The high dose chemotherapy regimens employed were cyclophosphamide, BCNU, and cisplatin in 3 cases, one case of BCNU, etoposide, Ara-C, and cyclophosphamide combination, and a regimen consisting of BCNU, etoposide, Ara-C, and melphalan. The total dose of BCNU used was 300-400 mg/$m^2$ and that of cyclophosphsmide was 6,000 mg/$m^2$. All of 5 patients received radiation therapy before this treatment. After an average duration of 14 weeks (4-26 weeks) of high-dose chemotherapy, patients developed cough, dyspnea and fever. The chest X-rays showed bilateral diffuse infiltration in 3 cases and the focal infiltration in the other 2 cases. All the patients received corticosteroid therapy as a treatment for the lung lesions. Two of them progressed to acute respiratory distress syndrome and died. Three patients recovered without residual lung lesion but one of them died of dilated cardiomyopathy. Conclusion: High-dose chemotherapy with peripheral blood stem cell transplantation especially which containing BCNU regimen may develop idiopathic pneumonia syndrome related to pulmonary toxicity and corticosteroid therapy may be bel1eficial in some cases.

Purpose : To analyze the treatment results of concurrent chemoradiation with oral 5-FU plus Gemcitabine or Paclitaxel for unresectable pancreatic cancer. Materials & Methods : The patients, who were diagnosed by imaging modalities or by explo-laparotomy, were treated with concurrent chemoradiation. Radiotherapy was delivered to primary tumor and regional lymph nodes, and the total dose was 45 Gy. Patients received Gemcitabine $1,000\;mg/m^2$ or Paclitaxel $50\;mg/m^2$ weekly and oral 5-FU daily The total number of cycles of chemotherapy ranged from 1 to 39 (median, 11 cycles). The follow-up period ranged from 6 to 36 months, Survival was analyzed using the Kaplan-Meier method. Results : Fifty-four patients between Jan. 1999 to Nov. 2001 were included in this study. Forty-two patients who completed the planned treatment were included in this analysis. The patients' age ranged from 37 to 73 years (median, 50 years) and the male to female ratio was 30:12. Treatment was interrupted for 12 patients due to: disease progression for 6 $(50\%)$, poor performance status for 4 $(33.3\%)$, intercurrent disease for 1 $(8.3\%)$, and refusal for 1 $(8.3\%)$. Response evaluation was possible for 40 patients. One patient gained complete remission and 24 patients gained partial remission, hence the response rate was $59\%$. The survival rates were $46.7\%\;and\;17.0\%$ at 1 year and 2 years, respectively with a median survival time of 12 months. Patients treated with Paclitaxel showed superior outcomes compared to those patients treated with Gemcitabine, in terms of both response rate and survival rate although this difference was not statistically significant. Grade III or IV hematologic toxicity was shown in 8 patients $(19\%)$, while grade III or IV non-hematologic toxicity was shown in 5 patients $(12\%)$. Conclusion : Concurrent chemoradiation with oral 5-FU and Gemcitabine or Paclitaxel improves both the response rate and survival rate in patients with unresectable pancreatic cancer. A prospective study should be investigated in order to improve both the patient selection and the treatment outcome as well as to reduce the toxicity.

Backgrounds : Gastric cancer is one of the most frequent causes of cancer-related deaths worldwide. Gastric cancer patients frequently exhibit distant metastasis at the time of diagnosis and at present, there is no standard regimen after operation or chemotherapy to prevent metastasis and recurrences. Aims : The objective of the study was to compare the overall survival and disease free survival in patients treated with wheel balance therapy (WBT) with patients treated with WBT alone or the combination of WBT and conventional therapy and see if there were any significant improvements in survival between the two groups. Setting & Design : East-West Cancer Center at Daejeon University: retrospective study. Materials & Methods : We retrospectively analyzed 62 patients with stage III (40 patients) and stage IV (22 patients) gastric cancer who have received operation or chemotherapy 2 months prior to beginning WBT. The patients followed the WBT protocol which includes herbal medicine such as PSM capsules, OnePlus syrup, or HAD capsules which prevent metastasis and recurrences. Overall survival and disease free survival were analyzed and the patients were treated for 89.55 weeks and 49.27 weeks (median value) for stages III and IV, respectively. Statistical analysis used : Overall survival and disease free survival were estimated using the Kaplan-Meier method and the WBT and combination treatment arms were compared using the log rank test. Results : For stage III, the 3 year overall survival was 78.5% and disease free survival was 78.3%. Metastasis and recurrence occurred in 13 of 40 patients (32.5%). For stage IV, the 2 year overall survival was 18.2% and disease free survival was also 18.2%. Metastasis and recurrence occurred in 19 of 22 patients (86.4%). No significant difference was found statistically between the WBT alone and combination treatment arms though the combination regimen showed superiority (overall survival p=0.5093, disease free survival p=0.5175). Conclusions : WBT yielded satisfactory results in prolonging survival and preventing metastasis and recurrence in gastric cancer patients. The major treatment unit of WBT is composed of herbal medications (HAD, PSM capsules, OnePlus syrup) and a randomized, prospective study should be carried out using only this treatment unit in the future.

Purpose: To report the early results of preopeartive concurrent radio-chemotherapy (CRCT) for treating rectal cancer. Materials and Methods: From June 1999 to April 2002, 40 rectal cancer patients who either had lesions with a questionable resectability or were candidates for sphincter-sacrificing surgery received preoperative CRCT. Thirty-seven patients completed the planned CRCT course. 45 Gy by 1.8 Gy daily fraction over 5 weeks was delivered to the whole pelvis in the prone position. The chemotherapy regimens were oral UFT plus oral leucovorin (LV) in 12 patients, intravenous bolus 5-FU plus LV in 10 patients, and intravenous 5-FU alone in 15 patients (bolus infusion in 10, continuous infusion in 5). Surgery was planned in 4$\~$6 weeks of the completion of the preoperative CRCT course, and surgery was attempted in 35 patients. Results: The compliance to the current preoperative CRCT protocol was excellent, where 92.5$\%$ (37/40) completed the planned treatment. Among 35 patients, in whom surgery was attempted after excluding two patients with new metastatic lesions in the liver and the lung, sphincter-preservation was achieved in 22 patients (62.9$\%$), while resection was abandoned during laparotomy in two patients (5.7$\%$). Gross complete resection was peformed in 30 patients, gross incomplete resection was peformed in one patient, and no detailed information on the extent of surgery was available in two patients. Based on the surgical and pathological findings, the down-staging rate was 45.5$\%$ (15/33), and the complete resection rate with the negative resection margin 78.8$\%$ (26/33). During the CRCT course, grade 3 $\~$4 neutropenia developed in four patients (10.8$\%$). Local recurrence after surgical resection developed in 12.1$\%$ (4/33), and distant metastases after the preoperative CRCT start developed in 21.6$\%$ (8/37). The overall 3-years survival rate was 87$\%$. Conclusion: Preoperative CRCT in locally advanced rectal cancer is well tolerated and can lead to high resection rate, down-staging rate, sphincter preservation rate, however, longer term follow-up will be necessary to confirm these results.
