Purpose To determine if there is a statistically significant difference in the computed tomography (CT)–guided trans-thoracic needle biopsy diagnostic rate, complication rate, and degree of pathologist confidence in diagnosis between core needle biopsy (CNB) and fine needle aspiration biopsy (FNAB). Methods A retrospective cohort design was used to compare the diagnostic biopsy rate, diagnostic confidence, and biopsy-related complications of pneumothorax, chest tube placement, pulmonary hemorrhage, hemoptysis, admission to hospital, and length of stay between 251 transthoracic needle biopsies obtained via CNB (126) or FNAB (125). Complication rates were assessed using imaging and clinical follow-up. Final diagnosis was confirmed via surgical pathology or clinical follow-up over a period of up to 10 years. Results CNB provided diagnostic samples in 91% and FNA in 80% of biopsies, which was statistically significant ( P < .05). The sensitivities for CNB and FNAB were 89% (85 of 95) and 95% (84 of 88), respectively. The specificity of CNB was 100% (21 of 21) and for FNAB was 81% (2 of 11) with 2 false positives in the FNAB group. The differences in complication rate was not statistically significant for pneumothorax (50% vs 46%; determined by routine postbiopsy CT), chest tube (2% vs 4%), hemoptysis (4% vs 6%), and pulmonary hemorrhage (38% vs 47%) between FNAB and CNB, respectively. Seven patients requiring chest tube were admitted to hospital, 2 in the FNAB cohort for an average of 2.5 days and 5 in the CNB cohort for an average of 4.6 days. Conclusions CNB provided more diagnostic samples with no statistical difference in complication rate.

Abstract Malignant phyllodes tumors are an uncommon breast tumor in clinical practice of surgery. The study population consisted of five consecutive patients. Each patient had complete clinical follow-up with annual mammograms and physical examination in a specialized breast clinic. They were surgically treated for with malignant phyllodes tumor of the breast. All patients are alive and well with a complete follow-up. The first 2 patients had a fine needle aspiration cytology and were surgically treated by a simple mastectomy. The remaining 3 patients were preoperatively diagnosed with core needle biopsy. These 3 patients were treated with a wide excision of the phyllodes tumor with at least a 1-cm margin of normal breast tissue. Mammography was 100% accurate in demonstrating a dense breast mass. In each patient ultrasound suggested heterogeneous internal echoes present in each malignant phyllodes tumor. Fine needle aspiration cytology was of no value in the diagnosis of a phyllodes tumor. Core needle biopsy is highly reliable in establishing a preoperative diagnosis. The most helpful clinical observation of a malignant phyllodes tumor was rapid growth and enlargement, which is frequently noted by the patient.

Objectives: To determine the diagnostic accuracy and complication rate of percutaneous transthoracic needle biopsy (PTNB) for subsolid pulmonary nodules and sources of heterogeneity among reported results. Methods: We searched PubMed, EMBASE, and Cochrane libraries (until November 7, 2020) for studies measuring the diagnostic accuracy of PTNB for subsolid pulmonary nodules. Pooled sensitivity and specificity of PTNB were calculated using a bivariate random-effects model. Bivariate meta-regression analyses were performed to identify sources of heterogeneity. Pooled overall and major complication rates were calculated. Results: We included 744 biopsies from 685 patients (12 studies). The pooled sensitivity and specificity of PTNB for subsolid nodules were 90% (95% confidence interval [CI]: 85–94%) and 99% (95% CI: 92–100%), respectively. Mean age above 65 years was the only covariate significantly associated with higher sensitivity (93% vs  85%, p = 0.04). Core needle biopsy showed marginally higher sensitivity than fine-needle aspiration (93% vs  83%, p = 0.07). Pooled overall and major complication rate of PTNB were 43% (95% CI: 25–62%) and 0.1% (95% CI: 0–0.4%), respectively. Major complication rate was not different between fine-needle aspiration and core needle biopsy groups (p = 0.25). Conclusion: PTNB had acceptable performance and a low major complication rate in diagnosing subsolid pulmonary nodules. The only significant source of heterogeneity in reported sensitivities was a mean age above 65 years. Advances in knowledge: This is the first meta-analysis attempting to systemically determine the cause of heterogeneity in the diagnostic accuracy and complication rate of PTNB for subsolid pulmonary nodules.
