AIM To assess the value of intraoperative diagnostic examination of frozen sections of lymph nodes removed during radical prostatectomy. METHODS Pelvic lymph nodes from patients with prostatic carcinoma were obtained (1) as frozen sections during radical prostatectomy, to exclude patients from non-curative surgery, and (2) as paraffin sections postoperatively from lymphadenectomy performed at...

BACKGROUND Sentinel lymph node (SLN) biopsy is the standard of care for the surgical assessment of the axilla during breast cancer surgery. However, the diagnostic accuracy of intraoperative frozen section analysis for confirming metastatic involvement of SLNs in cases of invasive lobular carcinoma (ILC) versus that of invasive ductal carcinoma (IDC) has generated controversy secondary to a fre...

Giant mature teratomas (>20 cm in diameters) sometimes may contain malignant immature elements or tissues. These small foci of immature tissues could be missed at frozen section resulting inadequate initial surgical intervention. There is no large series in the literature either showing the accuracy of frozen section on huge ovarian teratomas or concerning the adequate surgical approach at the ...

BACKGROUND Intraoperative pathologic diagnosis of bone and soft tissue lesions is an important yet challenging tool in clinical musculoskeletal oncology practice. There is limited information in the literature addressing the practical issues commonly encountered regarding intraoperative frozen section of musculoskeletal lesions. METHODS A literature review and retrospective review of practica...

A quantitative systematic review was performed to estimate the diagnostic accuracy of frozen sections in ovarian tumors. Studies that compared frozen sections and paraffin sections within subjects for diagnosis of ovarian tumors were included. Fourteen primary studies were analyzed, which included 3 659 women. For benign ovarian vs borderline/malignant tumor cases, the occurrence of a positive ...

BACKGROUND A standard intra-operative procedure for assessing sentinel lymph node metastasis in breast cancer patients has not yet been established. PATIENTS AND METHODS One hundred and thirty-eight patients with stage I breast cancer who underwent sentinel node biopsy using both imprint cytology and frozen section were analyzed. RESULTS Seventeen of the 138 patients had sentinel node invol...
