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.

It is known that aggressive treatment of chemotherapy, radiation and autogenous stem cell transplantation is effective for prevention of recurrence in the high-risk breast cancer patients. It was assumed that this procedure takes a longer time and decreases the quality of life more than the standard adjuvant chemotherapy. However, there are few studies comparing the quality of life of patients having bone marrow transplantation and adjuvant chemotherapy. Most of the studies were focused on the quality of life in one point of time, such as only during the early treatment stage, only overall quality of life rather than specific dimensions of the quality of life. The purposes of this study are 1) to identify the difference of the quality of life between two different treatment patterns, adjuvant chemotherapy and autogenous stem cell transplantation: 2) to identify the mostly affected dimension and the periods of time affected by the treatment patterns; and 3) to identify the trajectories of quality of life in each treatment pattern. This is a time series design that measures 4 different points of times. At the beginning of the study, 19 patients were placed in the chemotherapy group and 12 in the group of auto-peripheral blood stem cell transplantation. The inclusion criterion was the advanced disease stage of 3 or over with metastasis of more than 5 lymph nodes. The exclusion criteria were 1) anyone who has metastasis to other organ; 2) anyone who had psychological problems. Ferrell's Quality of Life Scale for Cancer Survivors 41 items on a 10 point scale was used. The QOL-CS includes 4 dimensions, which were labeled physical, psychological, social, and spiritual. The Cronbach‘s alpha of this scale was 0.89. Mann-Whitney U test and Friedman test were used to test each hypothesis. In comparison of the two groups, the quality of life of the bone marrow transplantation group dramatically increased at the 3rd and 6th month after transplantation, while the chemotherapy groups results stayed lower. The most affected dimension of the quality of life at the end of the treatment was the physical dimension. However, it and increased along with time, while the psychological dimension values remained low over the long-term period. Intensive nursing care is needed during the entire period of chemotherapy in all patients having chemotherapy, and is also required for right after cases of bone marrow transplantation.

The incidence of childhood cancer is greatest in the first year of life. Early diagnosis and advances in medicine have significantly improved outcomes of treatment resulting in higher survival rate; however, this progress comes at the expense of a higher incidence of adverse side effects because of more aggressive antineoplastic treatment strategies. The oral cavity, a trauma-prone environment, is extremely sensitive to toxicities from antineoplastic agents. Oral health care specialists, including pediatric and hospital dentists can support the oncology team by providing basic oral care, implementing oral care protocols, delivering emergency dental treatment, and assisting and/or managing oral complications from cancer therapy. This article covers the considerations in the dental management of pediatric patients undergoing cancer treatment, specifically chemotherapy, radiotherapy, and hematopoietic stem cell transplantation.

Purpose : In order to understand in vivo radiation damage modifying of bFGF on jejunal mucosa, bone marrow and the effect of bFGF on the growth of transplanted mouse sarcoma 180 tumor in mice. Materials and Methods : Mice were treated with $6\;{\mu}g$ of bFGF at 24 hours and 4 hours before exposing to 600 cGy, 800 cGy and 1,000 cGy total body irradiation (TBI), and then exposed to 3,000 cGy local radiation therapy on the tumor bearing thigh. Survival and tumor growth curve were plotted in radiation alone group and combined group of bFGF and irradiation (RT). Histologic examination was performed in another experimental group. Experimental groups consisted of normal control, tumor control, RT (radiation therapy) alone, $6\;{\mu}g$ bFGF alone, combined group of $3\;{\mu}g$ bFGF and irradiation (RT), combined group of $6\;{\mu}g$ bFGF and irradiation (RT). Histologic examination was peformed with H-E staining in marrow, jejunal mucosa, lung and sarcoma 180 bearing tumor. Radiation induced apoptosis was determined in each group with the DNA terminal transferase nick-end labeling method ($ApopTag^{\circledR}$ S7100-kit, Intergen Co.) Results : The results were as follows 1) $6\;{\mu}g$ bFGF given before TBI significantly improved the survival of lethally irradiated mice. bFGF would protect against lethal bone marrow syndrome. 2) $6\;{\mu}g$ bFGF treated group showed a significant higher crypt depth and microvilli length than RT alone group (p<0.05). 3) The bone marrow of bFGF treated group showed less hypocellularity than radiation alone group on day 7 and 14 after TBI (p<0.05), and this protective effect was more evident in $6\;{\mu}g$ bFGF treated group than that of $3\;{\mu}g$ bFGF treated group. 4) bFGF protected against early radiation induced apoptosis in intestinal crypt cell but might have had no antiapoptotic effect in bone marrow stem cell and pulmonary endothelial cells. 5) There was no significant differences in tumor growth rate between tumor control and bFGF alone groups (p>0.05). 6) There were no significant differences in histopathologic findings of lung and mouse sarcoma 180 tumor between radiation alone group and bFGF treated group. Conclusions : Our results suggest that bFGF protects small bowel and bone marrow from acute radiation damage without promoting the inoculated tumor growth in C3H mice. Improved recovery of early responding normal tissue and reduced number of radiation induced apoptosis may be possible mechanism of radioprotective effect of bFGF.

Tacrolimus, an immunosuppressant prescribed against graft-versus-host disease (GVHD) in patients with allogeneichematopoietic stem cell transplantation (HSCT), is affected to change its pharmacokinetic properties by various factors. For this reason, it is needed a close monitoring to adjust dosage amount in order to optimize the blood concentration of tacrolimus is located within the effective range. According to our in-house study, 62% of HSCT-patients were needed dosage-adjustment and it is necessary to optimize the current immunosuppressive regimen in clinical settings. A retrospective study was designed to evaluate the dosing regimen (converting ratio of IV:PO=1:4) of tacrolimus in HSCT patients (n=62). After collecting data from patient's profile and medical record, pharmacokinetic parameters were calculate and compared between the estimated and the actual values in the selected subjects (n=58). It was found that the bioavailabilty (BA) of oral tacrolimus was 40.5% very much different from that is known as 25%. It implies that the current protocol has a potent risk causes dose-related toxicities to the patients. Furthermore, analyses among factors demonstrated that there was no statistical significance between BA of tacrolimus and the variable factors. In the clinical perspectives, the current converting ratio of tacrolimus in patients with HSCT to be re-considered and an appropriate and optimal alternative regimen should be adopted to prevent GVHD and to increase the quality of life of patients.

Allogeneic hematopoietic stem cell transplantation (HSCT) is considered the optimal curative treatment for acute myeloid leukemia (AML), but some patients develop bone marrow relapse due to remnant leukemia, and few patients develop extramedullary relapse without bone marrow relapse. Isolated extramedullary relapse (IMER) is defined as extramedullary relapse without bone marrow relapse. IMER has been reported in various sites, including the skin, soft tissue, and central nervous system(CNS). Isolated CNS relapse is relatively rare and is associated with poor prognosis due to the absence of an optimal treatment for it. Reported herein is a case involving an adult AML woman who suffered from isolated extramedullary relapse in the CNS after allogeneic HSCT. She was treated with intrathecal chemotherapy and whole-brain and spine radiotherapy, followed by systemic chemotherapy. She is currently well, with no evidence of leukemia recurrence for over six years.

Background: Cyclosporine is an immunosuppressive agent used to treat and prevent graft versus host reaction (GVHR)-a complication associated with stem cell transplantation. This study aimed to develop a population pharmacokinetic model of cyclosporine and investigate factors affecting cyclosporine clearance in pediatric hematopoietic stem cell transplant patients. Methods: A total of 650 cyclosporine concentrations recorded in 65 patients who underwent hematopoietic stem cell transplantation were used. Data including age, sex, weight, height, body surface area (BSA), type of disease, chemotherapy before stem cell transplantation, type of donor, serum creatinine levels, total bilirubin concentration, hematocrit value, and type of concomitant anti-fungal agents and methylprednisolone used were retrospectively collected. Data related to cyclosporine dosage, administration time, and blood concentration were also collected. All data were analyzed using the non-linear mixed effect model; a two-compartment model with first-order elimination was used. Results: The population pharmacokinetic model of cyclosporine using the NONMEM program was as follows: $CL(L/h)=5.9{\times}(BSA/1.2)^{0.9}$, V2 (L) = 54.5, Q (L/h) = 3.5, V3 (L) = 1080.0, $k_a(h^{-1})=0.000377$. BSA was selected as a covariate of cyclosporine clearance, which increased with an increase in BSA. Conclusion: A population pharmacokinetic model for Korean pediatric hematopoietic stem cell transplant patients was developed, and the important factor affecting cyclosporine clearance was found to be BSA. The model might contribute to the development of the most appropriate dosing regimen for cyclosporine. Further studies on population pharmacokinetics should be carried out, prospectively targeting pediatric patients.

Background: The patients receiving hematopoietic stem cell transplantation (HSCT) are known to have a high incidence of breakthrough nausea and vomiting due to the conditioning regimen. The purpose of this study was to evaluate the adequacy of antiemetic therapy for breakthrough nausea and vomiting in patients receiving HSCT and to propose an effective treatment regimen. Methods: We retrospectively reviewed the electronic medical records of 109 adult patients. The collected data were used to identify (1) antiemetic and dosing regimens prescribed for controlling breakthrough nausea and vomiting, (2) the rate of patients who developed breakthrough nausea and vomiting, and (3) the percent of antiemetics prescribed on the day of symptom onset. Based on the National Comprehensive Cancer Network guideline, we assessed the suitability of antiemetics for breakthrough nausea and vomiting, and prescription timing. Results: All patients were prescribed pro re nata antiemetics. About 40.0%, 41.4%, and 18.6% of patients were using one, two, and three or more additional drugs for breakthrough nausea and vomiting, respectively. The most frequently administered drugs were intravenous metoclopramide (43.8%) and granisetron patch (36.2%). Breakthrough nausea and vomiting occurred in 87 patients (79.1%) and they developed symptoms 320 cases. About 220 cases (68.8%) were treated with additional antiemetics on the day of symptom onset and the rate of symptom resolution was only 10.3% (9 patients). Conclusion: The breakthrough nausea and vomiting in patients receiving HSCT occurred very frequently and was hard to control, thus requiring more rapid and aggressive treatments.

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.

Pulmonary complications occur in 40~60% of patients who receive hematopoietic stem cell transplantation (HSCT) and are a source of substantial morbidity and mortality. Acute eosinophilic pneumonia (AEP) is an uncommon, non-infectious pulmonary complication occurring in HSCT recipients. We now report the case of a 52-year-old man with AEP who was treated with allogenic HSCT due to acute myeloid leukemia. He complained of fever, cough and dyspnea 390 days after allogenic HSCT. He also had skin and hepatic graft versus host disease (GVHD). Hypoxemia, diffuse pulmonary infiltrates on a chest x-ray and eosinophilia in bronchoalveolar lavage fluid were also noted in several tests. His symptoms, pulmonary infiltrates, hepatic dysfunction and skin lesions rapidly improved after treatment with corticosteroid therapy. Our case supports the idea that AEP is a late phase non-infectious pulmonary complication and one of the manifestations of chronic GVHD.
