Transperineal core-needle biopsy of a rectal subepithelial lesion guided by endorectal ultrasound after contrast-enhanced ultrasound: A case report

BACKGROUNDRectal subepithelial lesions (SELs) are commonly seen in endoscopic examination, generally manifested as bumps with a smooth surface. Precise preoperative diagnoses for rectal SELs are difficult because abnormal tissues are not easily to be obtained by regular endoscopic forceps biopsy. Traditional guidance modalities of preoperative biopsy, including endoscopic ultrasound, computed tomography, and transabdominal ultrasound, are often unsatisfactory. An updated, safe, and effective biopsy guidance method is required. We herein report a new biopsy guidance modality—endorectal ultrasound (ERUS) combined with contrast-enhanced ultrasound (CEUS).CASE SUMMARYA 32-year-old woman complained of a mass inside the rectovaginal space for 9 years, which became enlarged within 1 year. A rectal SEL detected by endoscopy was suspected to be a gastrointestinal stromal tumor or exophytic uterine fibroid. Pathological diagnosis was difficult because of unsuccessful transabdominal core needle biopsy with insufficient tissues, as well as vaginal hemorrhage. A second biopsy was suggested after multiple disciplinary treatment discussion, which referred to a transperineal core needle biopsy (CNB) guided by ERUS combined with CEUS. Adequate samples were procured and rectal gastrointestinal stromal tumor was proved to be the pathological diagnosis. Imatinib was recommended for first-line therapy by multiple disciplinary treatment discussion. After the tumor shrunk, resection of the rectal gastrointestinal stromal tumor was performed through the posterior vaginal wall. Adjuvant therapy was applied and no recurrence or metastasis has been found by the last follow-up on December 13, 2019.CONCLUSIONTransperineal CNB guided by ERUS and CEUS is a safe and effective preoperative biopsy of rectal SELs yet with some limitations.     

Assessment of nondiagnostic ultrasound-guided fine needle aspirations of thyroid nodules

Thyroid nodules are common. Evaluation of patients with thyroid nodules typically includes fine needle aspiration biopsy (FNA), an approach that has proven to be accurate for the detection of thyroid cancer. Although the majority of biopsies are adequate for a cytological diagnosis, up to 20% will be insufficient or nondiagnostic. Current opinion suggests that such aspirates should be repeated, although no systematic study has investigated the usefulness of this approach, especially when ultrasound guidance is used to direct the initial FNA. We sought to define the predictors and optimal follow-up strategy for initial nondiagnostic ultrasound-guided FNAs of thyroid nodules. Data were collected for all patients at the Brigham and Women's Hospital Thyroid Nodule Clinic between 1995-2000 who underwent ultrasound-guided FNA of a thyroid nodule. All patients with nondiagnostic cytology were advised to return for a repeat ultrasound-guided FNA. Patient age, gender, nodule size, cystic content, solitary vs. multinodular thyroid, and nodule location were documented and evaluated as possible predictors of a nondiagnostic biopsy in a multivariable model. The rate of diagnostic cytology obtained on repeat ultrasound-guided FNA was calculated. A total of 1128 patients with 1458 nodules were biopsied over a 6-yr period. A total of 1269 aspirations (950 patients) were diagnostic, and 189 (178 patients) were nondiagnostic. The cystic content of each nodule was the only significant independent predictor of nondiagnostic cytology (P < 0.001). The fraction of specimens with initial nondiagnostic cytology increased with greater cystic content (P < 0.001 for trend). A diagnostic ultrasound-guided FNA was obtained on the first repeat biopsy in 63% of nodules and was inversely related to increasing cystic content of each nodule (P = 0.03). One hundred and nineteen patients with 127 nodules returned for follow-up as advised, and malignancy was documented in 5%. Despite ultrasound-guided FNA, there remains a significant risk of initial nondiagnostic cytology, largely predicted by the cystic content of each nodule. Repeat aspiration is often successful and should be the standard approach to such nodules, given their risk of malignancy.     

Comparison between core needle biopsy and excisional biopsy for breast neoplasm

This study aimed to explore clinical significance of core needle biopsy (CNB) in pathological diagnosis of breast neoplasm.Seventy one breast neoplasm samples were obtained from Tongzhou Maternal and Child Health Hospital of Beijing between the years of 2006 and 2014. Forty five specimens were obtained via CNB and cases offering 26 of them received neoadjuvant chemotherapy. Pathology, histology, and immunohistochemistry results were compared between CNB specimens and excisional biopsy.Upward and downward tendencies could be observed in CNB specimens and excisional biopsy, respectively, in all items. Tumor proportion of CNB tissues was (33 + 2)/45 = 77.78%, when ductal carcinoma in situ detected by both CNB and excisional biopsy was 31/45 = 68.89%, with a consistency of (31 + 3)/45 = 75.56%. Tumor thrombus detected by both CNB and excisional biopsy was 2/45 = 4.44%. Among cases receiving neoadjuvant chemotherapy, CNB and excisional biopsy, in mitotic figure, cytological scoring and histological grading, showed a total change rate of >50% (50%–75%), while changes in duct and cellular heteromorphism were not distinct. Cases showing changes were up to 73.08%, with 8/26 = 30.77% for rise and 11/26 = 42.31% for descent.CNB could be used for preoperative diagnosis of breast neoplasm, and help to determine proper treatment regimen, thus elevating the rate of breast conserving. However, this method still has several limitations, particularly in immunohistochemical tests of human epidermal receptor protein-2. Neoadjuvant chemotherapy may influence the accuracy of CNB diagnosis.     

Percutaneous image-guided cutting needle biopsy of the pleura in the diagnosis of malignant mesothelioma.

STUDY OBJECTIVES: Pleural fluid cytology and non-image-guided Abrams or Cope biopsies have sensitivities of approximately 30% for detecting malignant mesothelioma, and thoracoscopic biopsy has a sensitivity of approximately 90%. The difference between these two probably relates to obtaining adequate tissue. The use of immunohistochemical stains allows a firm diagnosis to be made from relatively small samples. This study explores whether percutaneous image-guided cutting needle biopsy (CNB) combined with immunohistochemistry is accurate in diagnosing pleural thickening due to mesothelioma. DESIGN: Retrospective review of image-guided CNB of pleural thickening performed on consecutive patients over 7 years by a single radiologist. SETTING: Teaching hospital chest radiology department. PATIENTS: Twenty-one adult patients with a final diagnosis of malignant mesothelioma were identified from 53 consecutive patients who underwent percutaneous image-guided CNB. All 21 patients had pleural thickening identified on contrast-enhanced CT, and all had a final histologic diagnosis of mesothelioma confirmed by postmortem examination or thoracoscopy. INTERVENTIONS: Fourteen-gauge and 18-gauge cutting needles were used. Biopsy guidance was by ultrasound in 6 patients and by CT in 15 patients. MEASUREMENTS AND RESULTS: A correct histologic diagnosis of malignant mesothelioma was made by CNB in 18 patients (86% sensitivity and 100% specificity). Complications included one chest wall hematoma and a small hemoptysis. Four patients with a pleural thickness of < or = 5 mm underwent biopsy, and all specimens were diagnostic for mesothelioma. CONCLUSIONS: Image-guided percutaneous CNB of pleural thickening is a safe procedure, with 86% sensitivity for detecting malignant mesothelioma. Pleural thickening of < or = 5 mm may be successfully sampled.

Fine needle aspiration and core needle biopsy in the diagnosis of lymphadenopathy of unknown aetiology

The clarification of enlarged lymph nodes is a common issue in clinical routine. By now, open surgery with complete lymph node extirpation, followed by histopathology, is considered as standard. We investigated the value of fine needle aspiration (FNA) and core needle biopsy (CNB) when supporting the conventional morphology by immunotyping. In total, 101 lymph nodes (reactive, n = 19; lymphoma, n = 46; metastatic, n = 36) were examined. CNB specimens were sufficient for unequivocal diagnosis by histopathology in 95 %. The FNA cytology allowed a correct diagnosis in 49 %. When supported by immunocytology, the success rate improved to 72 %. By accepting "suspicious of" as correct diagnosis, the ratio increased to 91 %. Additional use of flow cytometry in 46 samples minimized the "suspicious of" diagnoses and increased the proportion of unequivocal diagnoses in FNA specimens to 87 %. Flow cytometry allowed a correct subtyping in 20 of 21 B cell lymphoma but recognised only one of five Hodgkin lymphoma. All eight reactive samples were correctly diagnosed by flow cytometry. In summary, CNB allows a reliable clarification of an unclear lymphadenopathy. FNA is a powerful first diagnostic approach, especially if cytology is supported by immunocytology. The most substantial contribution of flow cytometry in FNA is the discrimination between reactive lymphadenopathy and B cell lymphoma.     

Ultrasound-assisted transthoracic biopsy: fine-needle aspiration or cutting-needle biopsy?

The present study compared the diagnostic yield of ultrasound-assisted cutting-needle biopsy (CNB) and fine-needle aspiration biopsy (FNAB) in chest lesions. A physician performed ultrasound and FNAB with a 22-G spinal needle in all patients, directly followed by a 14-G CNB in patients without contraindication. A total of 155 consecutive lesions arising from the lung (74%), pleura (12%), mediastinum (11%) or chest wall (3%) in patients with a final diagnosis of lung carcinoma (74%), other malignant tumours (12%), non-neoplastic disease (9%) or unknown (5%) were prospectively included. The overall diagnostic yield was 87%. Combined specimens were obtained in 123 lesions (79%). In these, yields of FNAB, CNB and both methods combined were 82, 76 and 89%, respectively. FNAB was significantly better than CNB in lung carcinoma (95 versus 81%) but CNB was superior in noncarcinomatous tumours and in benign lesions. On-site cytology was 90% sensitive and 100% specific for predicting a positive FNAB. One patient required drainage for pneumothorax (0.6%). Ultrasound-assisted fine-needle aspiration biopsy performed by chest physicians is an accurate and safe initial diagnostic procedure in patients with a high clinical probability of lung carcinoma. All other patients should undergo concurrent fine-needle aspiration biopsy and cutting-needle biopsy.
