Abstract Background: Core needle biopsy (CNB) is now more frequently used for the preoperative diagnosis of thyroid nodules. Based on morphology alone, 5%-20% of CNB samples cannot be determined as malignant or benign. Compared to fine-needle biopsy (FNB), samples collected by CNB are more accessible for various tests. Therefore, studying the application of biomarkers in distinguishing indeterminate CNB samples of thyroid nodules is a practical need. Methods: Patients with thyroid nodules with both CNB and matched resected specimens were reviewed. Cases classified as indeterminate lesions, follicular neoplasms and suspicious for malignancy were retrieved. All CNB samples were stained by immunohistochemistry (IHC) using antibodies against CK19, Galectin-3, HBME-1, and CD56 and detected by next-generation sequencing (NGS) using a target panel. With the help of these biomarkers, all CNB samples were reclassified. Taking the classification of resected specimens as the gold standard, the sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV) and accuracy of each biomarker for discriminating malignancy from benignity were calculated. Results: The sensitivity, specificity, PPV, NPV and accuracy were 93.55%, 60.00%, 93.55%, 60.00% and 88.89% for CK19; 93.55%, 40.00%, 90.63%, 50.00% and 86.11% for Galectin-3; 77.42%, 100.00%, 100.00%, 41.67% and 80.56% for HBME-1; 66.13%, 100.00%, 100.00%, 32.26% and 70.83% for CD56; and 91.94%, 100.00%, 100.00%, 66.67% and 93.06% for pathogenic mutation. Conclusions: The application of biomarkers is very effective in distinguishing indeterminate CNB samples of thyroid nodules. Gene testing by NGS using a target panel has very high accuracy. The limitation of tumor quantity is the main reason for the weakened power of NGS. IHC plays an important role in cases with negative NGS results. The combination of NGS and IHC is a reliable “rule in” test for malignancy.

AbstractCore needle biopsy (CNB) is now more frequently used for the preoperative diagnosis of thyroid nodules. Based on morphology alone, 5–20% of CNB samples cannot be determined as malignant or benign. Compared to fine-needle biopsy (FNB), samples collected by CNB are more accessible for various tests. Therefore, studying biomarkers’ application in distinguishing uncertain CNB samples of thyroid nodules is a practical need. Patients of thyroid nodules with both CNB and matched resected specimens were reviewed. Cases classified as indeterminate lesions, follicular neoplasms, and suspicious for malignancy were retrieved. All CNB samples were stained by immunohistochemistry (IHC) using antibodies against CK19, galectin-3, HBME-1, and CD56 and detected by next-generation sequencing (NGS) using an OncoAim® thyroid cancer multigene assay kit (Singlera Genomics) that detected 26 genes. Taking the resected specimens’ classification as the gold standard, the sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), accuracy of a single biomarker, and various combinations for discriminating malignancy from benignity were calculated. The sensitivity, specificity, PPV, NPV, and accuracy for preoperative malignancy evaluation were as follows. In the cohort of non-follicular-neoplasm-lesions (non-FN-lesion), they were 95.16%, 53.85%, 90.77%, 70.00%, and 88.00% for CK19; 95.16%, 38.46%, 88.06%, 62.50%, and 85.33% for galectin-3; 77.42%, 76.92%, 94.12%, 41.67%, and 58.00% for HBME-1; 66.13%, 100.00%, 100.00%, 38.24%, and 72.00% for CD56; 90.32%, 92.31%, 98.25%, 66.67%, and 90.67% for NGS; and 88.71%, 92.30%, 98.21%, 63.16%, and 89.33% for integrated IHC. In the cohort of follicular neoplasms (FN), they were 30.43%, 77.77%, 77.77%, 30.43%, and 43.75% for CK19; 73.91%, 66.67%, 85.00%, 50.00%, and 71.88% for galectin-3; 26.09%, 88.89%, 85.71%, 32.00%, and 43.75% for HBME-1; 26.09%, 100.00%, 100.00%, 34.62%, and 46.88% for CD56; 52.17%, 88.89%, 92.31%, 42.11%, and 62.50% for NGS; 82.61%, 66.67%, 86.36%, 60.00%, and 78.13% for integrated IHC; and 100%, 66.67%, 88.46%, 100%, and 90.63% for integrated IHC-NGS. The application of biomarkers in distinguishing uncertain CNB samples of thyroid nodules is available and capable. CD56 negative or NGS positive suggests malignancy strongly for both FN and non-FN-lesion, which may be used as a “rule in” tool. The negative predictive value of the integrated IHC and the integrated IHC-NGS implies a high possibility to be benign for non-FN-lesion and FN separately, which can work as a “rule out” tool. Considering the balance of specificity and sensitivity, NGS is the best for non-FN-lesion and the integrated IHC-NGS is the best for FN.

Abstract BACKGROUND:Early presentation and prompt diagnosis is the essential key in treatment of different variety of neoplastic as well as non-neoplastic breast disease. In this study usefulness of HRUSG, Mammography, FNAC and Core Needle Biopsy in correlation with histopathological pattern, was assessed.METHODS:After matching the criteria, 212 cases, were taken for this prospective, single center, observational study. RESULTS:Out of 212 cases, 163(76.88 %%) were benign lesions, 49(23.11%) were malignant and 1(0.47%) were of inflammatory pathology. Benign to malignant breast disease ratio was 3.3:1. Out of 49 malignant cases, 45 (91.83%) were ductal cell carcinoma and 4 (8.16%) was apocrine carcinoma. Maximum numbers of cancer patients were found in the 51- 60 year age groups.The sensitivity, specificity, Positive predictive value and Negative Predictive value of mammography in detecting carcinoma breast were 87.76%, 64.71%, 87.76% and 64.71% respectively. The sensitivity, specificity, PPV and NPV of HRUSG in detecting carcinoma breast were 85.71%, 90.18%, 72.41% and 95.45% respectively.Among benign lesions, 47 (28.83) % were diagnosed by mammography and 147(90.18) % were diagnosed by HRUSG. When these modalities were combined, >95% of the lesions was diagnosed accurately.CONCLUSIONS:Ultra sound used liberally as an adjunct to mammography, increase the cancer detection rate. Core needle biopsy is found more accurate but FNAC have limited value in evaluation of benign breast lump. This study also proves that preoperative categorization of breast lesions is utmost important for management of the patient and this will help to avoid unnecessary surgical treatment.

Objective This retrospective study was performed to investigate the diagnostic yield of percutaneous core needle biopsy (CNB) for suspected soft tissue lesions of the extremities. Methods The medical records of 139 consecutive patients who underwent percutaneous CNB for suspected soft tissue lesions of the extremities from January 2014 to December 2016 at a single institution were reviewed. The pathologic findings or clinical follow-ups were used to evaluate the performance of CNB. Alterations in the treatment regimen from pre- to post-biopsy were also analyzed. Complications, when present, were documented. Results In total, 141 biopsy procedures were performed in 139 patients. In total, 136 (96%) biopsies were successful, among which 5 were false-negative and 131 were diagnosed accurately. The sensitivity, specificity, accuracy, positive predictive value, and negative predictive value of CNB in the differentiation of malignant from benign lesions were 94%, 100%, 96%, 100%, and 90%, respectively. The treatment regimen was altered based on the biopsy findings in 25 cases. Two patients developed mild nerve injury but fully recovered during follow-up. Conclusions CNB is effective and safe, with high sensitivity, specificity, and accuracy for the diagnosis of soft tissue lesions, especially for differentiating malignant from benign lesions.
