Gastrointestinal stromal tumors (GISTs), which are the most common mesenchymal tumors of the gastrointestinal tract, have represented an important advance in oncology field with the success of molecular targeted therapy. Since the approval of the tyrosine kinase inhibitor (imatinib) in 2002, the survival of patients with advanced GISTs has significantly increased. Accurate histopathologic diagnosis of GISTs and multidisciplinary approach has become more important for successful management of GISTs. Recently, imatinib has become a standard treatment even in adjuvant setting, and regorafenib has been approved for advanced GIST after failure of imatinib and sunitinib. This review presents here the updated results of relevant clinical studies for the further revision to the guideline of Korean GIST study group. We hope this review will help enhance the quality of diagnosis, treatment, and care of patients with GIST in Korea.

BACKGROUND AND OBJECTIVES: Dizziness is the most common symptom of vertebrobasilar insufficiency (VBI), occurring in at least two-thirds of patients. The aim of our study is to document the clinical features and the treatment outcomes in the dizzy patients with VBI. SUBJECTS AND METHOD: A retrospective review of 36 patients suffering dizziness associated with VBI was performed at a tertiary referral center. RESULTS: The most frequent type and duration of dizziness were rotational (52.8%) and minute (55.6%). Sixteen patients (44.4%) reported that their episodes of dizziness occurred several times per a month. Half of the patients had at least one isolated episode of dizziness and in 25% VBI began with an isolated episode of vertigo. Twenty-three patients (63.9%) had risk factors for cerebrovascular diseases. Benign paroxysmal positional vertigo occurred in 27.8%, and 38.9% had a significantly decreased or absent response to caloric stimulation. On the dynamic posturography, visual dysfunction (33.4%) and vestibular dysfunction (19.4%) were observed. Thirty-two patients (88.9%) had abnormal finding on the pure tone audiometry. Nineteen (61.3%) of 31 patients experienced resolution or significant reduction of their episodes of dizziness with treatment. But one patient progressed to acute infarction. CONCLUSION: VBI-associated dizziness cause various clinical manifestations and there should be relevant differential diagnosis for episodic vertigo that last only minutes. We should pay special attention to the VBI in patients with isolated, transient dizziness and the risk factor of the cerebrovascular disease.

Supracondylar fracture of the femur is not as common as the shaft fracture. There is wide range of potential complication in the treatment of these fractures and the method of the treament and the evaluation of it's result is variable and remains controversial. Until 1960, we believed conservative treatment supirior to the operative treatment of the supracondylar fracture of the femur. But recently, anatomical reduction and internal fixation with early joint motion showed satisfactory results and is the trend of treatment of these fracture. The authors of this thesis performed treatment of supracondylar fracture of femur by utilizing Ender nails and screws in 13 cases during the period from October 1987 to November 1988 and it was found that operation was relatively simple, bleeding was little and early exercise of knee was allowed and even for patients of old age internal fixation could be maintained easily.
