연구실 소개
이정옥 교수의 연구실은 혈액학 및 종양학 분야에서 주로 활동하며, 빈혈과 철결핍의 유병률 및 위험 인자를 규명하는 인구기반 연구를 중심으로 진행하고 있습니다. 특히 철결핍 빈혈의 메커니즘과 관련된 분자표적, 예를 들어 NF-κB 경로와 관련된 유전자 발현 변화를 규명하며, 암 치료의 새로운 전략 탐색에도 기여하고 있습니다. 최근에는 항암제의 내성 및 재발 문제를 해결하기 위한 표적치료제의 장기적 효과와 재치료 전략에 대한 임상 연구도 수행하고 있습니다.

15This study assessed the prevalence of, and risk factors for, iron deficiency (ID) and iron deficiency anemia (IDA) among participants of the fifth Korean Health and Nutrition Examination Survey, 2010. Of 8,958 participants, 6,758 individuals ≥10 yr had sufficient data for the analysis of anemia and iron status. ID was defined as a transferrin saturation <10% or serum ferritin <15 µg/L. The prevalence of ID and IDA was 2.0% (95% confidence interval [CI], 1.3%-2.6%) and 0.7% (95% CI, 0.3%-1.0%), r

Our results showed that LCLs acquired expression phenotype changes involving expression of NF-kappaB pathway- and carcinogenesis-related genes during long-term subculture. These differentially expressed genes can be considered to be a gene signature of LCL immortalization or EBV-induced carcinogenesis. Clinical trait-associated expression phenotypes should prove useful in the discovery of new candidate genes for particular traits.
Adrenocortical carcinoma (ACC) is a rare malignancy with poor prognosis. Palliative chemotherapy can be considered in patients with metastatic disease. Although mitotane- or cisplatin-based chemotherapy regimens are widely used, the effects of these agents have been limited. We have experienced a case that showed a partial response with sunitinib after failure of mitotane-based cytotoxic chemotherapy. The clinical benefit from sunitinib persisted 7.5 months in this case. To our knowledge, this i
This study showed that PCP prophylaxis is highly effective against PCP infection and may help guide prevention of PCP during R-CHOP treatment in DLBCL patients.
Vemurafenib, an oral BRAF inhibitor, has demonstrated high response rates in relapsed/refractory (R/R) hairy cell leukemia (HCL). However, little is known about long-term outcomes and response to retreatment. Herein, we report the results of 36 patients with R/R HCL treated with vemurafenib from the United States arm of the phase 2 clinical trial (NCT01711632). The best overall response rate was 86%, including 33% complete response (CR) and 53% partial response (PR). After a median follow-up of
Paclitaxel has been shown to have clinical activity in the treatment of small cell lung cancer (SCLC). However, its role as third-line chemotherapy for SCLC after both etoposide- and camptothecin-based regimens has not been clarified.All patients with refractory SCLC who were treated with paclitaxel-based regimen as third-line chemotherapy between 2005 and 2011 in Seoul National University Bundang Hospital were reviewed retrospectively. Forty patients previously treated with both etoposide- and
Here, we describe our experience with secondary neurolymphomatosis (NL) in non-Hodgkin lymphoma patients, with the emphasis on the diagnosis process. A retrospective chart review of 12 patients from 3 tertiary academic centers between January 2005 and December 2015 was conducted. Secondary NL was diagnosed within a median interval of 10 months (range 5–41 months) after initial diagnosis of NHL. Painful neuropathy was present in 66.7%, but the diagnosis of NL was delayed in nine out of 12 patient
The activation of EGFR-HER2 contributes to the acquisition of resistance to pemetrexed in EML4-ALK rearranged non-small cell lung cancer. However, the inhibition of this alternative survival signaling pathway with RNAi against EGFR-HER2 and with afatinib overcomes this resistance.
Sorafenib had modest efficacy and tolerable toxicity in patients with metastatic HCC who had received fluoropyrimidine plus platinum-based chemotherapy.
