Background
Next-generation sequencing (NGS) is an approved test to select patients for BRAF V600E targeted therapy in Korea. However, the high cost, long turnaround times, and the need for sophisticated equipment and skilled personnel limit the use of NGS in daily practice. Immunohistochemistry (IHC) is a rapid and relatively inexpensive assay available in most laboratories. Therefore, in this study, we evaluate the usefulness of BRAF VE1 IHC in terms of predictive value and interobserver agreement in non–small cell lung cancers (NSCLCs).
Methods
A total of 30 cases with known BRAF mutation status were selected, including 20 cases of lung adenocarcinomas, six cases of colorectal adenocarcinomas, and four cases of papillary thyroid carcinomas. IHC for BRAF V600E was carried out using the VE1 antibody. Fifteen pathologists independently scored both the staining intensity and the percentage of tumor cell staining on whole slide images.
Results
In the lung adenocarcinoma subset, interobserver agreement for the percentage of tumor cell staining and staining intensity was good (percentage of tumor cell staining, intraclass correlation coefficient = 0.869; staining intensity, kappa = 0.849). The interobserver agreement for the interpretation using the cutoff of 40% was almost perfect in the entire study group and the lung adenocarcinoma subset (kappa = 0.815). Sensitivity, specificity, positive predictive value, and negative predictive value of BRAF VE1 IHC were 80.0%, 90.0%, 88.9%, and 81.8%, respectively.
Conclusions
BRAF VE1 IHC could be a screening test for the detection of BRAF V600E mutation in NSCLC. However, further studies are needed to optimize the protocol and to establish and validate interpretation criteria for BRAF VE1 IHC.

Abstract PDF

Molecular biomarker testing is the standard of care for non–small cell lung cancer (NSCLC) patients. In 2017, the Korean Cardiopulmonary Pathology Study Group and the Korean Molecular Pathology Study Group co-published a molecular testing guideline which contained almost all known genetic changes that aid in treatment decisions or predict prognosis in patients with NSCLC. Since then there have been significant changes in targeted therapies as well as molecular testing including newly approved targeted drugs and liquid biopsy. In order to reflect these changes, the Korean Cardiopulmonary Pathology Study Group developed a consensus statement on molecular biomarker testing. This consensus statement was crafted to provide guidance on what genes should be tested, as well as methodology, samples, patient selection, reporting and quality control.

Abstract PDF

Liquid biopsy for detection of mutation from circulating tumor DNA is a new technology which is attractive in that it is non-invasive. Epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKI) is an effective first line drug for advanced non-small cell lung cancer patients who harbor activating EGFR mutation. During the course of treatment, resistance against TKI arises which can be contributed to EGFR T790M mutation in about 50–60% of patients. Third generation TKI may overcome the resistance. In patients who cannot undergo tissue biopsy due to variable reasons, liquid biopsy is an excellent alternative for the detection of EGFR T790M mutation. However, this relatively novel method requires standardization and vigorous quality insurance. Thus, a standard set of guideline recommendations for liquid biopsy for EGFR mutation testing suitable for the Korean medical community is necessary. In this article, we propose a set of provisional guideline recommendations that was discussed and approved by the Cardiopulmonary Pathology Study Group of the Korean Society of Pathologists.

Abstract PDF

Targeted therapies guided by molecular diagnostics have become a standard treatment of lung cancer. Epidermal growth factor receptor (EGFR) mutations and anaplastic lymphoma kinase (ALK) rearrangements are currently used as the best predictive biomarkers for EGFR tyrosine kinase inhibitors and ALK inhibitors, respectively. Besides EGFR and ALK, the list of druggable genetic alterations has been growing, including ROS1 rearrangements, RET rearrangements, and MET alterations. In this situation, pathologists should carefully manage clinical samples for molecular testing and should do their best to quickly and accurately identify patients who will benefit from precision therapeutics. Here, we grouped molecular biomarkers of lung cancers into three categories—mutations, gene rearrangements, and amplifications—and propose expanded guidelines on molecular testing of lung cancers.

Abstract PDF Supplementary Material: Background
Since 2003, the Korean Society of Pathologists (KSP) has been officially providing medical advisory services (MAS). We reviewed the cases submitted to the KSP between 2003 and 2014. Methods: In total, 1,950 cases were submitted, most by private health insurance companies. The main purposes of the consultations were to clarify the initial diagnoses and to assign a proper disease classification code. We comprehensively reviewed 1,803 consultation cases with detailed information. Results: In spite of some fluctuations, the number of submitted cases has been significantly increasing over the 12 study years. The colon and rectum (40.3%), urinary bladder (14.2%), and stomach (6.9%) were the three most common tissues of origin. The most common diagnoses for each of the three tissues of origin were neuroendocrine tumor (50.7%), non-invasive papillary urothelial carcinoma (70.7%), and adenocarcinoma (36.2%). Regardless of the tissue of origin, neuroendocrine tumor of the digestive system was the most common diagnosis (419 of 1,803). Conclusions: In the current study, we found that pathologic consultations associated with private health insurance accounted for a large proportion of the MAS. Coding of the biologic behavior of diseases was the main issue of the consultations. In spite of the effort of the KSP to set proper guidelines for coding and classification of tumors, this review revealed that problems still exist and will continue to be an important issue.

Abstract PDF

Background
Analysis of mutations in the epidermal growth factor receptor gene (EGFR) is important for predicting response to EGFR tyrosine kinase inhibitors. The overall rate of EGFR mutations in Korean patients is variable. To obtain comprehensive data on the status of EGFR mutations in Korean patients with lung cancer, the Cardiopulmonary Pathology Study Group of the Korean Society of Pathologists initiated a nationwide survey. Methods: We obtained 1,753 reports on EGFR mutations in patients with lung cancer from 15 hospitals between January and December 2009. We compared EGFR mutations with patient age, sex, history of smoking, histologic diagnosis, specimen type, procurement site, tumor cell dissection, and laboratory status. Results: The overall EGFR mutation rate was 34.3% in patients with non-small cell lung cancer (NSCLC) and 43.3% in patients with adenocarcinoma. EGFR mutation rate was significantly higher in women, never smokers, patients with adenocarcinoma, and patients who had undergone excisional biopsy. EGFR mutation rates did not differ with respect to patient age or procurement site among patients with NSCLC. Conclusions: EGFR mutation rates and statuses were similar to those in published data from other East Asian countries.

Abstract PDF

Rearrangement of anaplastic lymphoma kinase (ALK) gene is the best predictor of response to crizotinib, an ALK tyrosine kinase inhibitor. However, the prevalence of the ALK fusion is low, so accurate patient identification is crucial for successful treatment using ALK inhibitors. Furthermore, most patients with lung cancer present with advanced-stage disease at the time of diagnosis, so it is important for pathologists to detect ALK-rearranged patients while effectively maximizing small biopsy or cytology specimens. In this review, we propose a guideline recommendation for ALK testing approved by the Cardiopulmonary Pathology Study Group of the Korean Society of Pathologists.

Abstract PDF

Mutations of the epidermal growth factor receptor (EGFR) are the strongest predictive factor for response to EGFR tyrosine kinase inhibitors (TKIs), such as gefitinib and erlotinib. EGFR TKIs are approved in Korea as a first-line treatment for lung cancer patients with mutated EGFR. Rapid and accurate EGFR mutation testing is essential for patient selection and establishing targeted therapies with EGFR TKIs. Thus, a standard set of guideline recommendations for EGFR mutation testing suitable for the Korean medical community is necessary. In this article, we propose a set of guideline recommendations for EGFR mutation testing that was discussed and approved by the Cardiopulmonary Pathology Study Group of the Korean Society of Pathologists.

Abstract PDF: Pseudohyperplastic prostatic adenocarcinoma is a rare histologic variant of prostatic adenocarcinoma that resembles benign nodular hyperplasia. Immunohistochemistry can verify the absence of basal cells, but it is frequently admixed with conventional adenocarcinoma. Because fine needle aspiration cytology is rarely performed in primary prostatic adenocarcinoma, the cytology of the pseudohyperplastic variant has not been described. We experienced a case of metastatic pseudohyperplastic adenocarcinoma in a pulmonary nodule of 75-year-old man. The cytologic smear was mostly composed of large, flat sheets with elongated branching papillae in a clean background. The sheets showed a well-defined honeycomb appearance of tall columnar, regularly arranged monotonous cells with little cytologic atypia. In subsequent prostatic biopsy, pseudohyperplastic variants were identified together with conventional adenocarcinoma of Gleason's grade 3 and 4. The cytologic features of pulmonary nodules were identical to those of pseudohyperplastic components of prostatic adenocarcinoma.

Abstract PDF: Potter's syndrome including bilateral renal agenesis or polycystic renal disease, bilateral pulmonary hypoplasia and characteristic face was first described in 1946. Although a great number of cases of Potter's syndrome was reported, Potter's syndrome with adult polycystic kidney disease(Potter type III) was very rarely found. In this report, we described an autopsy case of Potter's syndrome having adult polycystic kidneys disease, bilateral pulmonary hypoplasia and characteristic face in conjunction with multiple hepatic cysts, features of congenital hepatic fibrosis and a pancreatic cyst. Microscopically, all cysts were lined by cuboidal epithelial cells, showing positive for epithelial membrane antigen and cytokeratins.

Abstract PDF: To evaluate the clinical and histopathological significance of the proliferative activity in neoplastic and non-neoplastic thyroid lesions, we analyzed the mitotic count and the proliferating cell nuclear antigen labeling index (PCNA-LI) by immunohistochemistry as the proliferation- related markers. In this study included were surgically removed normal thyroid tissue (27 cases), adenomatous goiter (15 cases), Hashimoto's thyroiditis (5 cases), follicular adenoma (13 cases), follicular carcinoma (7 cases), papillary carcinoma (44 cases), poorly differentiated carcinoma (2 cases) and undifferentiated carcinoma (3 cases). The median PCNA-LI was 0 in normal thyroid tissue, 0.5 in adenomatous goiter, 6.2 in Hashimoto's thyroiditis, 1.2 in follicular adenoma, 4.8 in follicular carcinoma, 8.5 in papillary carcinoma, 60.8 in poorly differentiated carcinoma, and 55.2 in undifferentiated carcinoma (p=0.0001). Although PCNA-LI was exceptionally high in Hashimoto's thyroiditis, it was suggested that PCNA-LI could be used as a marker differentiating benign lesions from malignant neoplasm. Also, it could differentiate follicular adenoma from follicular carcinoma. Except clinical stage (p=0.0397), PCNA-LI was not related with sex, size, histologic subtype, and lymph node metastasis in papillary carcinoma. The presence of mitosis differentiated the neoplastic thyroid lesions from the non-neoplastic lesions (p<0.05), however, it could not divide benign and malignant neoplasm. These results suggest that an evaluation of the proliferative activity can help to differentiate the thyroid lesions. In addition, there was no significant correlation between the value of PCNA-LI and the presence of mitosis. It can be recommended to evaluate both the mitotic count and the PCNA-LI for determining the proliferative activity of the thyroid lesions.

Abstract PDF: Fine needle aspiration cytologyof a pulmonary mass was performed on a 51-year-old man who had a left testicular mass. Cytologic features were composed of a homogeneous population of malignant cells associated with a background of foamy and lacelike material. The cellular features were characterized by monomorphous cell proliferation of relatively regular large cells, generally isolated or grouped. Occasionally, fine branching stroma with large tumor cells and scanty lymphocytes were noted. The tumor cells had a round, regular nucleus, prominent round nucleoli, and a thin rim of cytoplasm containing large vacuoles or lacunae filled with glycogen. The fine needle aspiration cytologic diagnosis was highly consistent with metastatic seminoma from testis and less likely primary or other metastatic carcinoma. The diagnosis of resected testicular mass was classic seminoma. Despite the fact that cytopathologists were not familiar with diagnosis of seminoma due to clinician's lack of interest in fine needle aspiration cytology of germ cell tumors including seminoma, it appears that a diagnosis of this tumor should not be problematic in cytologic material if specific histologic criteria are applied.

Abstract PDF: BACKGROUND
:Prostatic adenocarcinoma makes up about 2% of the total cancer incidence and cancer death in Korean men, but the incidence of this malady is continuously increasing. So far, there have been only a few studies describing the pathologic characteristics of the prostatic adenocarcinoma in Korean patients. In this study, we analyzed 83 radical prostatectomy specimens by using mapping analysis to discover the clinico pathologic characteristics of Korean prostatic adenocarcinoma.
METHODS
The resected prostates were serially sectioned and embedded for histologic mapping. The clinico pathologic findings, including the Gleason score, tumor size, prostate intraepithelial neoplasia (PIN) and tumor invasion to the surrounding tissues, were examined.
RESULTS
The mean values were as follows: age, 64.1+/-6.6 years; serum prostate specific antigen (sPSA), 16.6+/-16.2 ng/mL; tumor volume, 22.3+/-22.4%; tumor size, 2.2+/-1.2 cm; and Gleason score, 6.9+/-0.9. The rate of high grade PIN was 79.7%. The Gleason score, tumor extent and T stage were statistically correlated (p<0.05).
CONCLUSIONS
Some prognostic factors such as sPSA and the Gleason scores showed significantly lower levels compared with those of the previous studies on Korean prostate adenocarcinoma (16-36 ng/mL vs 16.6 ng/mL and 7.3-7.7 vs 6.9, respectively). Although these values are still higher than those of the western studies, this study implies that the early detection of prostate adenocarcinoma is increasing in Korea.

Abstract PDF: With advance of diagnostic imaging technics, the detection rate of small hepatocellular carcinoma (HCC) has become much increased, but the questions whether the growth pattern and histologic nature of the HCC keep maintain the original gross and microscopic features with its advancement of tumor size remain still unclear. We reviewed 39 surgically resected hepatocellular carcinomas(HCCs) with a tumor size less than or equal to 3 cm in diameter(s-HCC), and their gross and microscopic features were compared with the HCCs bigger than 3 cm (i-HCC, 199 cases). Single nodular type(SN) was the most common gross type(60%) in s-HCCs, and was followed by single nodular type with perinodular extension(SNPE; 15.4%), multinodular-discrete type(10.3%) and multinodular-confluent type(5.1%). These figures contrasted to SNPE(42.2%) and SN(20.6%) in the i-HCCs. Of the 39 s-HCCs, 25 cases(64.1%) were encapsulated, and 14 cases(36%) demonstrated intratumoral fibrous septations, being contrasted to the i-HCCs in which fibrous septa formation was mord prominent but complete capsule formation was found only in 40.2% of the larger ones. Microscopically, the trabecular type was the most frequent one(53.9%), and increased with their size while the compact type transformed into trabecular one. Thirty three cases(84.6%) were associated with macronodular cirrhosis. Seropositivity for HBsAg was found in 26 cases(66.6%), and high serum alpha-fetoprotein level over 500 IU/L was found in 15 s-HCC cases(38.4%), while 53.3% in i-HCC. The above results suggest that HCCs change their pathologic features by increase of their size, and a comparison of the details with regard to the possible mechanisms involved is discussed.
