Background/Aims:
We evaluated the feasibility and long-term efficacy of the combination of cytarabine, idarubicin, and all-trans retinoic acid (ATRA) for treating patients with newly diagnosed acute promyelocytic leukemia (APL).
Methods:
We included 87 patients with newly diagnosed acute myeloid leukemia and a t(15;17) or promyelocytic leukemia/retinoic acid receptor alpha (PML-RARα) mutation. Patients received 12 mg/m2/day idarubicin intravenously for 3 days and 100 mg/m2/day cytarabine for 7 days, plus 45 mg/m2/day ATRA. Clinical outcomes included complete remission (CR), relapse-free survival (RFS), overall survival (OS), and the secondary malignancy incidence during a 20-year follow-up.
Results:
The CR, 10-year RFS, and 10-year OS rates were 89.7%, 94.1%, and 73.8%, respectively, for all patients. The 10-year OS rate was 100% for patients that achieved CR. Subjects were classified according to the white blood cell (WBC) count in peripheral blood at diagnosis (low-risk, WBC < 10,000/mm3; high-risk, WBC ≥ 10,000/mm3). The low-risk group had significantly higher RFS and OS rates than the high-risk group, but the outcomes were not superior to the current standard treatment (arsenic trioxide plus ATRA). Toxicities were similar to those observed with anthracycline plus ATRA, and higher than those observed with arsenic trioxide plus ATRA. The secondary malignancy incidence after APL treatment was 2.7%, among the 75 patients that achieved CR, and 5.0% among the 40 patients that survived more than 5 years after the APL diagnosis.
Conclusions
Adding cytarabine to anthracycline plus ATRA was not inferior to anthracycline plus ATRA alone, but it was not comparable to arsenic trioxide plus ATRA. The probability of secondary malignancy was low.

Submental or submandibular intubation has been reported to cause fewer complications than tracheostomy. However, the risk of infection is always inherent because oral wounds are exposed to microbial flora and bacteria in the oral cavity. A novel technique of submandibular intubation was devised to reduce infection and injury to the soft tissues. We would like to report a novel safe technique that can be performed in patients requiring submental or submandibular intubation. This is the first report of submandibular intubation using a sterile disposable camera cable drape. This novel technique of submandibular intubation is safer, more sterile, easier, and less invasive than conventional submandibular intubation.

Background:
The success rate of intubation under direct laryngoscopy is greatly influenced by laryngoscopic grade using the Cormack-Lehane classification. However, it is not known whether grade under direct laryngoscopy can also affects the success rate of nasotracheal intubation using a fiberoptic bronchoscpe, so this study investigated the same. In addition, we investigated other factors that influence the success rate of fiberoptic nasotracheal intubation (FNI).
Methods:
FNI was performed by 18 anesthesiology residents under general anesthesia in patients over 15 years of age who underwent elective oral and maxillofacial operations. In all patients, the Mallampati grade was measured.Laryngeal view grade under direct laryngoscopy, and the degree of secretion and bleeding in the oral cavity was measured and divided into 3 grades. The time required for successful FNI was measured. If the intubation time was > 5 minutes, it was evaluated as a failure and the airway was managed by another method. The failure rate was evaluated using appropriate statistical method. Receiver operating characteristic (ROC) curves and area under the curve (AUC) were also measured.
Results:
A total of 650 patients were included in the study, and the failure rate of FNI was 4.5%. The patient's sex, age, height, weight, Mallampati, and laryngoscopic view grade did not affect the success rate of FNI (P > 0.05). BMI, the number of FNI performed by residents (P = 0.03), secretion (P < 0.001), and bleeding (P < 0.001) grades influenced the success rate. The AUCs of bleeding and secretion were 0.864 and 0.798, respectively, but the AUC of BMI, the number of FNI performed by residents, Mallampati, and laryngoscopic view grade were 0.527, 0.616, 0.614, and 0.544, respectively.
Conclusion
Unlike in intubation under direct laryngoscopy, in the case of FNI, oral secretion and nasal bleeding had a significant effect on FNI difficulty than Mallampati grade or Laryngeal view grade.

PURPOSE: The purpose of this study was to evaluate the imaging features of complex sclerosing lesions of the breast and to assess the rate of upgrade to breast cancer. METHODS: From March 2008 to May 2012, seven lesions were confirmed as complex sclerosing lesions by ultrasonography-guided core needle biopsy. Final results by either surgical excision or follow-up imaging studies were reviewed to assess the rate of upgrade to breast cancer. Two radiologists retrospectively analyzed the imaging findings according to the Breast Imaging Reporting and Data System classification. RESULTS: Five lesions underwent subsequent surgical excision and two of them revealed ductal carcinoma in situ (n=1) and invasive ductal carcinoma (n=1). Our study showed a breast cancer upgrade rate of 28.6% (2 of 7 lesions). Two lesions were stable on imaging follow-up beyond 1 year. The mammographic features included masses (n=4, 57.1%), architectural distortion (n=2, 28.6%), and focal asymmetry (n=1, 14.3%). Common B-mode ultrasonographic features were irregular shape (n=6, 85.7%), spiculated margin (n=5, 71.4%), and hypoechogenicity (n=7, 100%). The final assessment categories were category 4 (n=6, 85.7%) and category 5 (n=1, 14.3%). CONCLUSION: The complex sclerosing lesions were commonly mass-like on mammography and showed the suspicious ultrasonographic features of category 4. Due to a high underestimation rate, all complex sclerosing lesions by core needle biopsy should be excised.

The consensus guideline development committee of Korean Society of Gynecologic Oncology was reconvened in March 2012. The committee consisted of 36 experts representing 12 university hospitals and professional organizations. The objective of this committee was to develop standardized guidelines for cervical cancer screening tests for Korean women and to distribute these guidelines to every clinician, eventually improving the quality of medical care. Since the establishment of the consensus guideline development committee, evidence-based guidelines have either been developed de novo considering specific Korean situations or by adaptation of preexisting consensus guidelines from other countries. Recommendations for cervical cancer screening tests, management of atypical squamous and glandular cells, and management of low-grade and high-grade squamous intraepithelial lesions were developed. Additionally, recommendations for human papillomavirus DNA testing and recommendations for adolescent and pregnant women with abnormal cervical screening test results were also included.

OBJECTIVE: The purpose of this study is to evaluate the clinical utility of adding lateral approach to conventional vertical approach for prone stereotactic vacuum-assisted breast biopsies. MATERIALS AND METHODS: From April 2010 to May 2012, 130 vacuum-assisted stereotactic biopsies were attempted in 127 patients. While a vertical approach was preferred, a lateral approach was used if the vertical approach failed. The success rate of biopsies utilizing only a vertical approach was compared with that using both vertical and lateral approaches and the breast thickness for both procedures was measured and compared with that for vertical approach. In addition, pathology results were evaluated and the causes of the failed biopsies were analyzed. RESULTS: Of the 130 cases, 127 biopsies were performed and 3 biopsies failed. The success rate of the vertical approach was 83.8% (109/130); however, when the lateral approach was also used, the success rate increased to 97.7% (127/130) (p = 0.0004). The mean breast thickness was 2.7 +/- 1 cm for the lateral approach and 4 +/- 1.2 cm for the vertical approach (p < 0.0001). The histopathologic results in 76 (59.8%) of the biopsies were benign, 23 (18.1%) were high-risk lesions, and 28 (22.0%) were malignant. The causes of biopsy failure were thin breasts (n = 2) and undetected difficult lesion location (n = 1). CONCLUSION: The addition of lateral approach to conventional vertical approach in prone stereotactic vacuum-assisted breast biopsy improved the success rate of stereotactic biopsy, especially in patients with thin breasts.

BACKGROUND: Decay accelerating factor (DAF/CD55), regulates the complement system by accelerating decay of the C3 convertase, has been described in several malignancies, however, the clinicopathologic significance of CD55 and its receptor CD97 has not been fully investigated. We examined the expression patterns of both CD55 and CD97 and their association with clinicopathologic parameters in colorectal cancers (CRCs). METHODS: Expression patterns of CD55 and CD97 in the stroma and tumor cells at tumor center and invasive front were examined in 130 CRCs, and their significance was statistically evaluated. RESULTS: CD55-high stroma was correlated with tumor border (p=0.006) and invasion depth (p=0.013). CD55-high tumor cells at tumor center and invasive front were correlated with histologic grade, and CD55-high tumor cells at invasive front with tumor, node and metastasis (TNM) stage (p<0.05). CD97-high stroma was correlated with lymph node metastasis (p=0.016) and TNM stage (p=0.030). CD97-high tumor cells at tumor center and invasive front were correlated with tumor size and CD97-high tumor cells at tumor center with tumor border (p<0.05). Patients with CD55-high stroma showed poor overall and recurrence-free survival (p<0.05) in univariate analysis, and were independently associated with short recurrence-free survival (p=0.025) in multivariate analysis. CONCLUSIONS: Stromal CD55 overexpression would be an indicator of adverse clinical outcome and a useful prognostic factor.

PURPOSE: The purpose of this study was to evaluate the B-mode sonographic and sonoelastographic features of high risk lesions of the breast. MATERIALS AND METHODS: From April 2009 to February 2010, 1390 patients with breast lesions underwent US-guided core-biopsy. Among them, 13 lesions were confirmed to be pure sclerosing adenosis by subsequent surgical excision or on imaging follow-up of more than 1 year. Two radiologists retrospectively analyzed the B-mode sonography according to the Breast Imaging Reporting and Data System classification. The sonoelastographic images were classified into 5 elasticity scores according to the Itoh classification and the strain ratio between the mass and the surrounding fat tissue was reviewed. We considered the sonoelastographic patterns to be suspicious for the case with a score of 4 and 5 and a strain ratio of more than a 2.24. RESULTS: The common B-mode sonographic features of sclerosing adenosis were an irregular shape (69.2%, 9 of 13), an indistinct margin (92.3%, 12 of 13), hypoechogenicity (76.9%, 10 of 13) and category 4A, a low suspicion of malignancy (61.5%, 8 of 13). The common sonoelastographic features were a score of 2 (42%, 6 of 13) and a strain ratio < 2.24 (69.2%, 9 of 13). CONCLUSION: Sclerosing adenosis showed suspicious B-mode sonographic findings, but it had benign sonolastographic features.

OBJECTIVES: The Korean College of Neuropsychopharmacology and the Korean Academy of Schizophrenia developed the Korean medication algorithm project for schizophrenia (KMAP) to aid clinical decisions. The purpose of this study was to investigate problems and revision of Korean Medication Algorithm for Schizophrenia after feasibility test. METHODS: A total of 108 schizophrenia patients were enrolled at 19 centers and treated according to the algorithm. Prescribing investigators were able to change the recommended treatment strategies of the algorithm if necessary. All subjects were assessed over a 4-month period. Appropriateness of choice, dosage, duration and switch of antipsychotics and definition of treatment response were examined. RESULTS: Compliance of 1(st) choice antipsychotics in KMAP was favorable. Atypical antipsychotics which is a 1(st) stage drug selected first was above 84%, especially in case of no previous medical history was nearly all. In case that shift of stage was needed, there is a trend that combination treatment stage (6(th) stage) and clozapine treatment stage (5(th) stage) were preferred to rather than 3(rd) stage and 4(th) stage (typical antipsychotics and atypical antipsychotics treatment stage). The rates of switching antipsychotics at the time points other than CDP (critical decision points) was low and the reason was almost the side effects. So the compliance of CDPs in KMAP was good in case of insufficiency of treatment response. Also the reasons why many investigators continued using current antipsychotics without switching despite insufficiency of treatment response were definition of treatment response, discrepancy between brief symptom rating scale for negative symptom and decision of clinicians. In addition, compliance of co-existence symptoms and side effect of medication in KMAP was favorable. CONCLUSION: It is some difference from clinical practice such as stage of antipsychotics, definition of treatment response and usefulness of brief symptom rating scale for negative symptom. But the majority apart from points of preceding paragraph is feasible in clinical practice. These results are essential to revise the next version of KMAP.
