CT-guided transthoracic biopsy: histopathologic results and complication rates

PURPOSE

We aimed to investigate the effectiveness and complications of transthoracic CT-guided biopsy techniques.

METHODS

A total of 94 CT-guided percutaneous transthoracic biopsy procedures performed in 85 patients were retrospectively evaluated. Core biopsy technique was used in 87 procedures and transthoracic fine-needle aspiration biopsy was used in seven procedures.

RESULTS

Diagnostic results were achieved in 79 of 94 biopsy procedures. Pathology results were malignant in 54 patients, suspicious for malignancy in three patients, benign in five patients, and benign nonspecific in 17 patients. Specific diagnoses were obtained in 59 patients (62.8%) using core biopsy, but no specific diagnosis could be reached with transthoracic fine-needle aspiration biopsy. Complications included pneumothorax in 27 patients (28.7%) and parenchymal hemorrhage during and after the procedure in eight patients (8.5%).

CONCLUSIONS

CT-guided percutaneous transthoracic needle biopsy is a highly accurate procedure for histopathological diagnosis of thoracic masses. In addition, percutaneous transthoracic biopsy has an acceptably low complication rate and it reduces the need for more invasive surgical procedures.Since the beginning of the 21st century, lung cancer has been cited as one of the most common causes of death (1). World Health Organization declared lung cancer as the first leading cause of death in men and second in women, among all types of cancers (2).Percutaneous transthoracic biopsies are performed either using fine-needle aspiration biopsy (transthoracic fine-needle aspiration biopsy, TTFNAB) method or using the incisional or core biopsy method. Incisional biopsy and core biopsy are used to obtain a part of tissue from the lesion for histological diagnosis. On the other hand, TTFNAB is used to obtain aspiration material, which is used for cytological examination and lesion diagnosis (3, 4).Indications of transthoracic needle biopsy include solitary and multiple pulmonary nodules, mass lesions, persistent focal infiltration, consolidation, presence of cavities and abscesses, pleural lesions, and mediastinal and hilar mass diagnosis (3, 5).The aim of this study was to investigate the technique, suitability, and complications in CT-guided transthoracic biopsy of lung masses.     

Fine-needle and incisional biopsy technics in the percutaneous puncture of abdominal space-occupying lesions

Cutting needles for guided percutaneous biopsy of abdominal tumors have been introduced in recent years and provide better results than fine-needle aspiration. A total of 292 biopsies in 273 patients were evaluated retrospectively. The diagnostic accuracy was 83.4% with cutting needles and 54.4% for fine-needle aspiration. The sensitivity in detection of malignancy was 86.8% and 88.6%, respectively. The location of the lesion to be biopsied determined whether CT or US was used for guidance. US control was used in biopsies of the upper abdomen; CT was preferred for guidance in the retroperitoneal space and in the pelvis. The caliber of the cutting needles in transperitoneal or transintestinal biopsy was limited to 19 gauge. The complication risk using cutting needles up to 18 gauge is no higher than for fine-needle aspiration biopsy if suitable access routes are selected.     

The diagnostic value of chest X-ray combined with fine-needle aspiration biopsy in patients suspected for pulmonary hamartomas

Hamartomas of the lung are usually discovered incidentally during chest X-ray in asymptomatic patients. Their differentiation from lung carcinoma or metastases may not be possible by radiography. Transthoracic fine-needle aspiration biopsy is an important and safe diagnostic tool in that differentiation. In our institution we have been practising this method since 1971. By combining clinical information, radiological appearance of the pulmonary lesion and the cytological report we achieved safe diagnosis in 31 of 33 patients. Surgical biopsy was avoided in 29 patients. Based on this series we recommend transthoracic fine-needle aspiration biopsy as the first diagnostic step in evaluating solitary pulmonary lesions suspected of pulmonary hamartomas.     

Transthoracic needle aspiration biopsy: accuracy of cytologic typing of malignant neoplasms

A correlation was made between the cytologic and the histologic diagnoses of 162 patients who underwent transthoracic fine-needle aspiration biopsy in whom histologic proof of the nature of the aspirated lesion was available. Compared to the histologic diagnosis, the specific cell-type cytologic diagnosis was usually in agreement when reported as squamous cell carcinoma (86%), adenocarcinoma (86%), or small cell anaplastic carcinoma(86%). In patients with a known extrapulmonary primary malignant neoplasm, the cytologic specimen was extremely helpful in identifying a new pulmonary lesion as metastatic rather than as a primary lesion in the lung. These results warrant the more extensive use of fine-needle aspiration biopsy in patients with pulmonary neoplasms in whom the specific cell type of the malignant neoplasm has important implications in therapy.     

MR fluoroscopy-guided transthoracic fine-needle aspiration biopsy: feasibility

The purpose of this study was to evaluate the feasibility of using an open-configuration magnetic resonance (MR) imaging system with MR fluoroscopic guidance to perform percutaneous transthoracic fine-needle aspiration biopsy in patients with lung masses. Percutaneous transthoracic aspiration biopsies were performed with MR fluoroscopic guidance in 14 patients. The masses were 2-7 cm in diameter (mean, 4.1 cm). The needle was positioned by using a free-hand technique with MR fluoroscopic guidance. The needle tip reached the target lesion, and biopsy was performed. Analysis of the biopsy specimens facilitated a specific diagnosis in all patients. Pneumothorax was noted in two patients (14%) with chronic obstructive pulmonary disease. Study results showed that the described MR fluoroscopy-guided transthoracic biopsy technique can be used safely and successfully for lung masses. MR fluoroscopy can be used to reach the target lesion easily and accurately.

Surveillance CT and the prompt use of CT-guided fine-needle aspiration in patients with head and neck cancer who have undergone surgery

OBJECTIVE: The purpose of this study was to assess the usefulness of prompt CT-guided fine-needle aspiration in the evaluation of suspected tumor recurrence seen on surveillance images of patients who had undergone surgery for head and neck cancer. SUBJECTS AND METHODS: We reviewed 32 patients who had undergone CT-guided fine-needle aspiration after surgery for head and neck cancer. CT-guided fine-needle aspiration was performed with a 22-gauge spinal needle and a cytopathologist was present to assess the adequacy of the biopsy sample. As many as five needle passes were made. RESULTS: Of the 32 cases, pathologic findings revealed squamous cell carcinoma (n = 27), mucoepidermoid carcinoma (n = 2), neuroendocrine carcinoma (n = 1), papillary thyroid carcinoma (n = 1), and adenocarcinoma (n = 1). In 20 cases (62.5%) the results of CT-guided fine-needle aspiration were positive for tumor recurrence, whereas in 11 cases (34.4%) the results were negative. In one case (3.1%) the results were nondiagnostic. Of the 11 patients with negative findings on CT-guided fine-needle aspiration, two patients had a subsequent recurrence that was not at the biopsy site. There were no complications from the procedure. CONCLUSION: When a radiologist who is trained in head and neck imaging identifies with CT a possible early recurrence of tumor, the prompt use of CT-guided fine-needle aspiration is an effective way to diagnose these tumors so that appropriate treatment can be initiated.     

MDCT-Guided Transthoracic Needle Aspiration Biopsy of the Lung Using the Transscapular Approach

The purpose of this study is to report our preliminary experience using MDCT-guided percutaneous transthoracic needle aspiration biopsy using the transscapular approach in the upper posterolateral lung nodules, an area that it is difficult or hazardous to reach with the conventional approach. Five patients underwent CT-guided percutaneous transthoracic needle aspiration biopsy of the lung via the transscapular approach. A coaxial needle technique was used in all patients. Biopsy was successful in all patients. No major complications were encountered. One patient developed a minimal pneumothorax next to the lesion immediately after biopsy, which resolved spontaneously. MDCT-guided percutaneous transthoracic needle aspiration biopsy of the lung via the transscapular approach is an effective and safe procedure that reduces the risk of pneumothorax in selected patients.     

Image-Guided Percutaneous Needle Biopsy for Benign and Malignant Bone Tumors: Systematic Review and Meta-Analysis

PurposeTo compare the diagnostic yield and accuracy of both image-guided core-needle biopsy (CNB) and fine-needle biopsy and evaluate the benefit of performing fine-needle biopsy in addition to CNB in patients with suspected benign and malignant bone tumors.Materials and MethodsA systematic search was performed on March 10, 2021, to determine whether fine-needle aspiration (FNA) plays any role when performed alone or in combination with CNB. The included studies were aggregated for the pooled estimates of diagnostic yield and histologic accuracy of image-guided percutaneous needle biopsy of bone tumors. Twenty-nine studies published between 1996 and 2021 were included.ResultsWhen all patients with bone tumors were included, the rates of diagnostic yield and accuracy of FNA and CNB were 88.5% and 82.5% and 91.4% and 92.7%, respectively; the rates of both the methods combined were 96.5% and 94.1%, respectively; and for the lytic subgroup, the rates of diagnostic yield and accuracy of CNB and both the methods combined were 94.3% and 100% and 98.9% and 90.4%, respectively. A P value of <.05 was considered statistically significant.ConclusionThe present meta-analysis showed that core biopsy alone outperformed fine-needle biopsy alone in all categories of benign and malignant tumors. Additionally, the diagnostic yield was improved when FNA was used in addition to CNB for lytic bone lesions.     

Coaxial transthoracic fine-needle biopsy in patients with a history of malignant lymphoma.

Efficacy and safety of coaxial transthoracic fine-needle biopsy were evaluated in 54 patients with a history of malignant lymphoma and new chest lesions. Twenty-one patients had recurrent lymphoma. Correct diagnosis was made in 17 of the 21 patients (81%) after one biopsy. The sensitivity increased to 95% with repeat needle biopsy in three patients. Immunophenotyping (determining phenotype by means of immunologic examination) was essential for a definitive diagnosis of lymphoma in three patients. Non-lymphomatous malignancies were correctly diagnosed in 14 patients. An infectious organism was identified in 11 of 19 patients (58%) with benign lesions. Pneumothorax occurred in eight patients (15%), necessitating placement of a chest tube in two (4%). Mild hemoptysis was observed in four patients (7%). The authors conclude that coaxial transthoracic fine-needle biopsy in patients with a history of lymphoma is safe and accurate. The use of large cutting needles or surgical biopsy can be restricted to patients with false-negative findings at percutaneous biopsy and to patients in whom histologic transformation of lymphoma is suspected.
