AbstractAbstract PDF
Background

The Bethesda System for Reporting Thyroid Cytopathology (BSRTC) uses six diagnostic categories to standardize communication of thyroid fine-needle aspiration (FNA) interpretations between clinicians and cytopathologists. Since several studies have questioned the diagnostic accuracy of this system, we examined its accuracy in our hospital.

Methods

We calculated the incidences and malignancy rates of each diagnostic category in the BSRTC for 1,730 FNAs that were interpreted by four cytopathologists in Gangnam Severance Hospital between October 1, 2011, and December 31, 2011.

Results

The diagnostic incidences of categories I-VI were as follows: 13.3%, 40.6%, 9.1%, 0.4%, 19.3%, and 17.3%, respectively. Similarly, the malignancy rates of these categories were as follows: 35.3%, 5.6%, 69.0%, 50.0%, 98.7%, and 98.9%, respectively. In categories II, V, and VI, there were no statistically significant differences in the ranges of the malignancy rates among the four cytopathologists. However, there were significant differences in the ranges for categories I and III.

Conclusions

Our findings suggest that institutions that use the BSRTC should regularly update their diagnostic criteria. We also propose that institutions issue an annual report of incidences and malignancy rates to help other clinicians improve the case management of patients with thyroid nodules.

AbstractAbstract PDF
Background

The incidence of early colorectal epithelial neoplasm (ECEN) is increasing, and its pathologic diagnosis is important for patient care. We investigated the incidence of ECEN and the current status of its pathologic diagnosis.

Methods

We collected datasheets from 25 institutes in Korea for the incidence of colorectal adenoma with high grade dysplasia (HGD) and low grade dysplasia in years 2005, 2007, and 2009; and early colorectal carcinoma in the year 2009. We also surveyed the diagnostic terminology of ECEN currently used by the participating pathologists.

Results

The average percentage of diagnoses of adenoma HGD was 7.0%, 5.0%, and 3.4% in years 2005, 2007, and 2009, respectively. The range of incidence rates of adenoma HGD across the participating institutes has gradually narrowed over the years 2005 to 2009. The incidence rate of early colorectal carcinoma in the year 2009 was 21.2%. The participants did not share a single criterion or terminology for the diagnosis of adenoma HGD. The majority accepted the diagnostic terms that distinguished noninvasive, mucosal confined, and submucosal invasive carcinoma.

Conclusions

Further research requirements suggested are a diagnostic consensus for the histopathologic diagnosis of ECEN; and standardization of diagnostic terminology critical for determining the disease code.

AbstractAbstract PDF
BACKGROUND
The Korean Bone and Soft Tissue Pathology Study Group of the Korean Society of Pathologists conducted a nationwide retrospective analysis of soft tissue sarcoma (STS) to provide the clinicopathologic characteristics of STS within the population of the Republic of Korea.
METHODS
The cases of STS were collected during a 7-year period (2001-2007) from 19 institutes in Korea. All cases were classified according to the histologic criteria proposed by the World Health Organization. Clinicopathologic data were reviewed.
RESULTS
Data from 722 patients (median age, 50 years) were collected. Data showed a slight male predominance. The most frequent types of STS in decreasing order were liposarcoma, malignant fibrous histiocytoma, leiomyosarcoma, and synovial sarcoma. STS occurred throughout the body, although approximately half (47.8%) were located in the extremities. The majority of STS was histologically classified as high grade with a large tumor size (>5 cm). The overall survival rate for the patients was 76.3% (median follow-up time, 26 months; range, 1 to 89 months). Histologic grade, tumor size, American Joint Committee on Cancer stage, tumor site, and resection status were prognostic. Significant independent adverse prognostic factors were large tumor size (>5 cm) and tumor site other than extremities.
CONCLUSIONS
We reported the distribution and characteristics of STS in the Republic of Korea.

AbstractAbstract PDF
BACKGROUND
The Hematopathology Study Group of the Korean Society of Pathologists conducted a nation-wide retrospective analysis of Korean pediatric lymphoma, to provide pathologic data on pediatric/adolescent lymphoma subtypes and features.
METHODS
All lymphoma cases of all age groups were collected during a recent 2 year-period (2005-2006) from 32 institutes in Korea. Among 3,686 lymphoma patients, 142 who were age 18 or less were classified according to the World Health Organization (WHO) classification.
RESULTS
Among 142 pediatric/adolescent lymphoma patients, Hodgkin lymphoma accounted for 21 (14.8%) and non-Hodgkin lymphoma (NHL) for 121 (85.2%). Hodgkin lymphoma appears to be more common in the pediatric/adolescent age group than in the all-ages group (14.8% vs 4.4%). T- and natural killer cell-NHL was more common in the pediatric/adolescent age group than in the all ages group (46.3% vs 22%). The majority of Korean pediatric/adolescent NHL cases was composed of Burkitt lymphoma, T- or B-lymphoblastic lymphoma, anaplastic large-cell lymphoma, and diffuse large B-cell lymphoma. For lymphoma patients under the age of 6 years, most had B-lymphoblastic or Burkitt lymphoma, which commonly presented at extranodal sites.
CONCLUSIONS
The distribution of lymphoma subtypes in the pediatric/adolescent age group is quite different from the distribution of adults, but it was quite similar to distribution in Western countries.

AbstractAbstract PDF
Eighty cases of malignant effusion were cytologically studied to elucidate the incidence of primary tumor site and cytologic characteristics of each tumor types. Eighty fluid specimens were composed of 43 ascitic, 35 pleural, and 2 pericardial effusion and primary tumor site had been confirmed by histology. The frequent primary sites were stomach (22 cases, 28%), lung (21 cases, 26%), ovary (11 cases, 14%), liver (7 cases, 9%), and breast (4 cases, 5%). The principal malignant tumors were adenocarcinoma (56 cases, 70%), squamous cell carcinoma (7 cases, 9%), liver cell carcinoma (7 cases, 9%), small cell carcinoma (4 cases, 5%), and non-Hodgkin}s lymphoma (4 cases, 5%). The distinctive cytologic findings according to primary tumor types were as follows ; the gastric adenocarcinomas were mainly characterized by isolated cells and irregular clusters sometimes with signet ring cells. Papillary serous cystadenocarcinoma of ovary showed frequently papillary clusters and occasional psammoma bodies. Breast carcinoma of ductal type showed cell balls with smooth margins. Colonic adenocarcinoma showed rather irregular clusters or palisading pattern of cylindrical cells. Metastatic squamous cell carcinoma, liver cell carcinoma, small cell carcinoma, and non-Hodgkin}s lymphoma showed also characteristic features. These findings indicate that the cytological features observed in the great majority of malignant effusion are similar to those of primary tumor types, which are very helpful to indentify the primary tumor site.
