High dose therapy followed by autologous peripheral blood stem cell transplantation as a first line treatment for multiple myeloma: a Korean Multicenter Study.
We conducted a phase II multicenter trial to estimate the response and survival of patients with newly diagnosed multiple myeloma to high dose melphalan therapy followed by autologous peripheral blood stem cell transplantation. Eligible patients who had undergone induction with vincristine, adriamycin and dexamethasone (VAD) should have adequate cardiac, pulmonary and renal function (creatinine <2 mg/dL). Melphalan at 200 mg/m2 was used as a conditioning regimen. Eighty patients were enrolled from 13 centers. The median age of the patients was 53 yr (range; 20 to 68 yr). The initial stage was IA/IIA/IIB/IIIA/IIIB in 3/8/1/54/14 patients, respectively. Beta2-microglobulin, CRP and LDH were increased in 74, 42 and 34% of the patients examined. Cytogenetic data were available in 30 patients, and 6 patients showed numeric or structural abnormalities. Two therapy-related mortalities occurred from infection. Among the 78 evaluable patients, CR/PR/MR/NC/PD were achieved in 48/26/2/1/1 patients, respectively. After a median follow-up of 30 months, the median overall and event-free survivals were 66 months (95% CI: 20-112) and 24 months (95% CI: 18-29), respectively. This study verifies the efficacy and feasibility of high dose melphalan therapy with autologous stem cell transplantation in newly diagnosed multiple myeloma
Gemcitabine and Infusional 5-Fluorouracil in Advanced Pancreatic Cancer: A Clinical Benefit Response-Oriented Phase II Study
Purpose: Gemcitabine and 5-fluorouracil (5-FU) are two compounds with reproducible activity against advanced pancreatic carcinomas. To evaluate the activity and feasibility of this combination chemotherapy, a multi-institutional phase II study was performed.
Materials and Methods: Twenty patients (maleခfemale 15ခ5, median age: 60.5 years), with histologically verified locally advanced or metastatic pancreatic carcinomas, were enrolled between April 2000 and March 2002.
Gemcitabine was administered by intravenous injection at the doses of 1,000 mg/m2 on days 1, 8 and 15, and 5-FU 800 mg/m2/day, was given by continuous intravenous infusion on days 1~5. The treatment was repeated every 4 weeks. The clinical benefit response (CBR) was a composite of the pain, Karnofsky performance status and body weight change measurement.
Results: Nineteen of the twenty patients were assessable for response. The median follow-up duration was 4.6 months (0.4~15.2 months). Five patients achieved a partial response and eight a stable disease. The overall response rate was 25.0%. The CBR was assessable in 12 patients.
The overall CBR was 41.7% (5/12). The median survival of all the patients was 8.0 months. Grade 3~4 toxicities included neutropenia (9.3%) and thrombocytopenia (5.3%).
Conclusion: This study suggested that gemcitabine, combined with infusional 5-FU, was well tolerated, and produced modest antitumor activity and symptomatic relief in advanced pancreatic cancer patients. (Cancer Res Treat. 2003;35:213-217

Hepatitis B Core Antigen Expression in Hepatocytes Reflects Viral Response to Entecavir in Chronic Hepatitis B Patients
High-dose versus low-dose cyclophosphamide in combination with G-CSF for peripheral blood progenitor cell mobilization
Background: To compare the mobilizing effects and toxicities of two different doses of cyclophosphamide (CY) plus lenograstim (glycosylated G-CSF), we performed a prospective randomized study by enrolling patients suffering with either high-risk Non-Hodgkin's lymphoma (NHL) or breast cancer undergoing ablative chemotherapy. Methods: The NHL patients received 4 cycles of CHOP and the breast cancer patients received 2-3 cycles of FAC (FEC) adjuvant chemotherapy. Then, the patients were randomly allocated to receive CY 4 g/m2 (arm A) or 1.5 g/m2 (arm B) in combination with lenograstim. Large volume leukapheresis was carried out and it was continued daily until the target cell dose of 2 × 106 CD34+ cell/kg was reached. Results: Twenty-seven patients were enrolled in the study. The median number of leukaphereis sessions actually performed was 2.5 sessions in arm A and 3 sessions in arm B. The target cell dose was obtained with the median number of one leukapheresis session in both arms of the study (p=0.09). The collected number of CD34+ cells in the leukapheresis products was higher in arm A than arm B (22.4 vs. 9.9 × 106/kg, respectively, p=0.05). Grade III or IV leukopenia was present in 14/15 patients (94%) in arm A and in 1/12 patients (8%) in arm B (p<0.0001). Grade III or IV thrombocytopenia was present in 8/15 patients (54%) in arm A, but this was not present in any patients of arm B (p=0.0004). Neutropenic fever occurred in 6/15 patients (40%) in arm A, and in 1/12 patients (8%) in arm B (p=0.09). The hematological recovery of the leukocytes and platelets after transplantation was not statistically different between the two doses. Conclusion: Low-dose CY plus lenograstim is a safe and effective mobilizing regimen
High-dose Versus Low-dose Cyclophosphamide in Combination with G-CSF for Peripheral Blood Progenitor Cell Mobilization
Safety and efficacy of nilotinib in adult patients with chronic myeloid leukemia: a post-marketing surveillance study in Korea
© 2022 Korean Society of Hematology.Background Nilotinib is a tyrosine kinase inhibitor approved by the Ministry of Food and Drug Safety for frontline and 2nd line treatment of Philadelphia chromosome-positive chronic myeloid leukemia (Ph+ CML). This study aimed to confirm the safety and efficacy of nilotinib in routine clinical practice within South Korea. Methods An open-label, multicenter, single-arm, 12-week observational post-marketing surveillance (PMS) study was conducted on 669 Korean adult patients with Ph+ CML from December 24, 2010, to December 23, 2016. The patients received nilotinib treatment in routine clinical practice settings. Safety was evaluated by all types of adverse events (AEs) during the study period, and efficacy was evaluated by the complete hematological response (CHR) and cytogenetic response. Results During the study period, AEs occurred in 61.3% (410 patients, 973 events), adverse drug reactions (ADRs) in 40.5% (271/669 patients, 559 events), serious AEs in 4.5% (30 patients, 37 events), and serious ADRs in 0.7% (5 patients, 8 events). Furthermore, unexpected AEs occurred at a rate of 6.9% (46 patients, 55 events) and unexpected ADRs at 1.2% (8 patients, 8 events). As for the efficacy results, CHR was achieved in 89.5% (442/494 patients), and minor cytogenetic response or major cytogenetic response was achieved in 85.8% (139/162 patients). Conclusion This PMS study shows consistent results in terms of safety and efficacy compared with previous studies. Nilotinib was well tolerated and efficacious in adult Korean patients with Ph+ CML in routine clinical practice settings.N
