Modern medical oncology has introduced various anti-cancer drugs since the World War I and II. Unlike for the solid tumors, hematological malignancies had been documented some limitations for curing it with chemotherapeutic agents only. In 1960, Dr. Nowell and Dr. Hungerford had discovered elongated chromosome (Philadelphia chromosome) which has documented as a product of translocation between 9th and 22nd chromosome in the patients with chronic myeloid leukemia. In 1970s, immunochemistry technique using monoclonal antibody has spread world widely and from 1990s, flow cytometry method has been available. In appreciation of these evolutions in basic science, the treatment strategy ofhematological malignancies has changed from the chemotherapeutic agents to targeted agents. Among the targeted agents, some drugs are newly developed and others are recreated as anti-cancer drugs after long-time of discard because of their toxicities or teratogenic effects. Nowadays, we are in the middle of flood of targeted agents, for example, tyrosinekinase inhibitors, epidermal growth factor receptor blockers, farnesyl transferase inhibitors, histone deacetylase inhibitors, and etc. In 21st century, the optimal treatment of hematological malignancies should follow a tailor- made strategy according to the patient and disease itself. In the present article, some representative agents will be introduced in accordance with target diseases.

PURPOSE: The main issue with the current ultrasonography (US) guidelines is the overestimation of malignant and indeterminate nodules as they do not aid in making decisions to treat patients. To overcome this, new US guidelines for thyroid nodules that have been shown to be better correlated with cytologic results have been proposed. We also suggested specific indications for US-guided fine needle aspiration (FNA) using the new US guidelines. METHODS: Clinical and pathologic data from 925 patients and 1,419 thyroid nodules were retrospectively collected. All subjects underwent US- and US-guided FNA at Department of Surgery, Wonju Christian Hospital, between March 2010 and July 2011. Sensitivity, specificity, accuracy, positive predictive value (PPV), and negative predictive value (NPV) were calculated for both the current guidelines and the new guidelines. RESULTS: The accuracy, sensitivity, specificity, PPV, and NPV for the current guidelines in predicting malignancy were 24.1%, 99.3%, 62.2%, 25.0%, and 99.8%, respectively. The accuracy, sensitivity, specificity, PPV, and NPV for the new guidelines in predicting malignancy were 66.0%, 96.0%, 86.7%, 47.7%, and 99.4%, respectively. CONCLUSION: The use of the new US guidelines allow for a more accurate and specific diagnosis and a better treatment plan than the current guidelines. Additionally, the use of the new FNA guidelines may help prevent unnecessary FNAs and promote cost-effective follow-up for patients.

PURPOSE: To determine the difference among the results of three kinds of methods for the treatment of simple retinal detachment. METHODS: We analyzed the patients undergoing primary pars plana vitrectomy(Group I: January to June, 1997), scleral buckling(Group II: January to June, 1996) and pneumatic retinopexy(Group I: January to June, 1995) to treat simple retinal detachments with retinal breaks located in peripheral retina, smaller than one clock hour, breaks in the superior eight clock hours, multiple breaks extending less than two clock hours and no severe retinal traction. RESULTS: The final visual acuity was 5/200 or more(functional success) in 19 eyes(100%) of Group I, 19 eyes(100%) of Group cII and 20 eyes(90.9%) of Group I. Primary retinal reattachment(anatomical success) was in 17 eyes(89.5%) of Group I, 19 eyes(100%) of Group II and 18 eyes(81.8%) of Group I with no statistically significant difference among the three groups. The final retinal reattachment rate was 100% in all groups. CONCLUSIONS: This result suggests the scleral buckling might be a little bit better for the treatment of simple retinal detachment, though each of three surgical methods showed no statistical difference of functional and anatomical results.

As modern society becomes increasingly complex, there has been a steady increase in violence, as well as in automobile and industrial accidents. This has resulted in an increased incidence of facial injuries, including mandibular fractures. Many methods have been advocated to achieve reestablishment of normal feature and function. The choice generally depends upon such factors as location of the fractures, displacements, status of the dentition and favorability of the fracture line. Many cases of mandibular fracture are treated by intermaxillay fixation using an arch bar or bite block(acrylic splint)for rapid bone union and minimal displacement. However, there had been some problems, such as discomfort to patients, limitation to eating and weight loss, poor oral hygiene, and temporomandibular joint ankylosis. As a consequence, we have modified the shape of the acrylic splint and method of fixation for circum-mandibular fixation instead of intermaxillary fixation. Acrylic splints are rigid, strong, easily adjusted and repaired, translucent, lightweight and well tolerated by the oral mucosa. The splints are properly secured to each tooth and bind all the teeth together as a single unit. Authors have used modified acrylic splints as tools of circum-mandibular fixation in 12 cases of mandibular symphysis and body fracture from May 1997 to August 1998, achieving the results of very good occlusal relationship, oral hygiene and comfort to patients.
