Touch Imprint Cytology and Stereotactically-Guided Core Needle Biopsy of Suspicious Breast Lesions: 15-Year Follow-up

[Interventional techniques for the breast]

BACKGROUND

Interventional methods of the breast serve as percutaneous minimally invasive diagnostic tools in case of suspicious findings in the breast or axilla. Further indications are lesion localization and the minimally invasive therapeutic approach.

OBJECTIVES

Aim of this paper is to give an overview of the existing methods, their indications and the imaging techniques for guidance. On the basis of the most recent publications, clinical management is described.

Touch Imprint Cytology: A Rapid and Accurate Method for Diagnosis of Oral Cancer

OBJECTIVES

Touch imprint cytology (TIC) is a rapid and cheap method and can be used as an adjunct to biopsy for the evaluation of suspected malignancy. We evaluated the advantages and limitations of TIC for the preoperative diagnosis of oral squamous cell carcinoma.

STUDY DESIGN

We used 280 incisional biopsies of clinically suspected oral squamous cell carcinoma and compared TIC diagnosis to histopathological sections. The sensitivity, specificity, and diagnostic accuracy of TIC were evaluated.

RESULTS

A total of 201 (82.5%) cases were diagnosed as malignant, 22 (7.9%) cases were diagnosed as suspicious of malignancy, and 54 (19.3%) cases as benign/negative on TIC. The overall sensitivity of TIC was 98.2%, specificity was 89.3%, the positive-predictive value 97.3%, and the negative-predictive value was 92.6%. The accuracy of the test was 96.4%.

CONCLUSIONS

TIC is an accurate, simple, rapid, and cost-effective method that aids the diagnosis of oral squamous cell carcinoma but does not replace incisional biopsy. The cytologic examination of imprints of biopsies also helps determine the adequacy of the specimen for histologic examination.
