연구실 소개
이기형 교수의 연구실은 비소세포성 폐암을 중심으로 표적항암치료의 효과와 내성을 해소하기 위한 분자기반 치료 전략을 연구하고 있습니다. 특히 EGFR 변이를 가진 환자군에서의 타겟 치료 반응, 장기적 생존과 관련된 요법 패러다임 전환에 초점을 맞추고 있으며, 분자진단과 맞춤형 치료의 융합을 통해 개인화된 암 치료의 실현 가능성을 모색하고 있습니다. 또한 항암치료 중 발생할 수 있는 부작용 관리와 환자생존율 향상 전략에 대해서도 종합적인 연구를 진행하고 있습니다.

15PURPOSE: The ISTANA (IRESSA as Second-line Therapy in Advanced NSCLC-KoreA) study compared gefitinib with docetaxel in patients with advanced or metastatic non-small cell lung carcinoma (NSCLC) pretreated with platinum-based chemotherapy. EXPERIMENTAL DESIGN: We conducted a multicenter, randomized, open-label phase III trial of gefitinib (250 mg/d) versus docetaxel (75 mg/m(2) day 1 every 3 weeks) in patients with advanced or metastatic NSCLC treated with one previous platinum-based chemotherapy
PURPOSE: A subset of patients with adenocarcinoma of the lung who had never smoked cigarettes showed excellent tumor responses to gefitinib therapy. To evaluate the efficacy of gefitinib as a first-line therapy in this subgroup of patients, we conducted a phase II study. EXPERIMENTAL DESIGN: Eligible patients had no smoking history, stage IIIB or IV adenocarcinoma, Eastern Cooperative Oncology Group performance status 0 to 2, and adequate organ functions. Treatment consisted of daily oral admini
BACKGROUND: The goals of this multinational retrospective study were to describe treatment patterns and survival outcomes by receipt of molecular testing and molecular status of patients with advanced non-small cell lung cancer (NSCLC). METHODS: This chart review study, conducted in Italy, Spain, Germany, Australia, Japan, Korea, Taiwan, and Brazil, included 1440 patients with newly diagnosed advanced (stage IIIB/IV) NSCLC initiating systemic therapy from January 2011 through June 2013, with fol
BACKGROUND: The epidermal growth factor receptor (EGFR) has been reported to be overexpressed in anaplastic thyroid carcinoma (ATC). In vitro studies have shown that EGFR tyrosine kinase inhibitors (TKIs) greatly inhibit cellular growth and induced apoptosis in the ATC cell lines, while somatic mutations in the tyrosine kinase domain or an increased gene copy number are associated with increased sensitivity to TKIs in non-small cell lung cancer. AIM: To investigate the prevalence of EGFR overexp
BACKGROUND: In a previous pilot study, adrenal suppression was found to be common after antiemetic dexamethasone therapy in cancer patients. The objective of this large prospective multicenter study was to confirm the incidence and factors associated with secondary adrenal suppression related to antiemetic dexamethasone therapy in cancer patients receiving chemotherapy. METHODS: Chemotherapy-naïve patients who were scheduled to receive at least three cycles of highly or moderately emetogenic che
In the LUX-Lung 3/LUX-Lung 6/LUX-Lung 7 trials, 10-12% of afatinib-treated patients were LTRs. Long-term afatinib treatment was independent of tolerability-guided dose adjustment and had no detrimental impact on safety or PROs.
The efficacy and safety of nivolumab in Korean patients with advanced or recurrent squamous or non-squamous NSCLC are consistent with previous reports.
PURPOSE: Pegylated granulocyte-colony-stimulating factor (G-CSF) is frequently used to prevent febrile neutropenia (FN) in patients undergoing chemotherapy with a high risk of myelosuppression. This phase II/III study was conducted to determine the adequate dose of pegteograstim, a new formulation of pegylated G-CSF, and to evaluate the efficacy and safety of pegteograstim compared to pegfilgrastim. METHODS: In the phase II part, 60 breast cancer patients who were undergoing DA (docetaxel and do
Stroke is the most common neurologic complication of sickle cell disease. Acute chest syndrome (ACS) is a known risk factor for stroke in this population. Two patients (a 12-year-old boy and a 6-year-old girl) developed acute change of mental status and focal neurologic signs during episodes of ACS. The clinical and radiologic findings were compatible with acute necrotizing encephalitis, a variant of acute demyelinating encephalomyelitis. Patients with acute neurologic deterioration in conjuncti
