As the false-negative rates of axillary ultrasonography (AUS) (21%-48%) are not optimal, the demand for axillary surgery remains even if AUS is negative. The aim of this study is to determine the histopathological and tumor characteristics associated with false-negative AUS results.

We evaluate the preoperative breast cancer (BC) characteristics that affect the diagnostic accuracy of axillary ultrasound (US) and determine the reliability of US in the different subgroups of BC pat...
Spontaneous regression of a malignant tumor is defined as "the partial or complete disappearance of a malignant tumor in the absence of any treatment." Herein, we report a case of occult breast cancer...
The FilmArray® meningitis/encephalitis panel detects the 14 most frequent pathogens causing meningitis and/or encephalitis. The cases of FilmArray´s false negative in bacterial meningitis are rarely...
The sentinel node biopsy following neoadjuvant chemotherapy (SN FNAC) study has shown that in node-positive (N+) breast cancer, sentinel node biopsy (SNB) can be performed following neoadjuvant chemot...
Background In patients who are expected to achieve axillary pathologic complete response (pCR) after neoadjuvant chemotherapy (NAC), omission of axillary lymph node (LN) dissection could prevent morbi...
Sentinel lymph node dissection (SLND) after NAC, aimed to reduce the rate of unnecessary axillary lymphadenectomy, is not a standard of care in case of patient with previously involved nod...
A downstaging of axillary tumor-spread can be achieved in about 40% of the patients receiving neoadjuvant chemotherapy (NACT). The impact of NACT on loco-regional tumor control has not yet...
This is an open-label, multicenter, 2x2 factorial design, randomized controlled, Phase III study comparing the disease free survival after randomisation in patients treated with 3 cycles o...
The advent of mammography and increased awareness of breast cancer has resulted in detection of smaller tumors, the majority of which would not have had metastasized to the axillary lymph ...
AUS/FNAC allows the identification of tumors without axillary tumor involvement, or with low axillary tumor burden, many of which do not benefit from SLNB, in the staging of early breast c...
Negative test results in subjects who possess the attribute for which the test is conducted. The labeling of diseased persons as healthy when screening in the detection of disease. (Last, A Dictionary of Epidemiology, 2d ed)
Arteries originating from the subclavian or axillary arteries and distributing to the anterior thoracic wall, mediastinal structures, diaphragm, pectoral muscles, mammary gland and the axillary aspect of the chest wall.
Those characteristics that distinguish one SEX from the other. The primary sex characteristics are the OVARIES and TESTES and their related hormones. Secondary sex characteristics are those which are masculine or feminine but not directly related to reproduction.
The edges of tissue removed in a surgery for assessment of the effectiveness of a surgical procedure in achieving the local control of a neoplasm and the adequacy of tumor removal. When the margin is negative or not involved by tumor (e.g., CANCER) it suggests all of the tumor has been removed by the surgery.
A malignant tumor arising from the nuclear layer of the retina that is the most common primary tumor of the eye in children. The tumor tends to occur in early childhood or infancy and may be present at birth. The majority are sporadic, but the condition may be transmitted as an autosomal dominant trait. Histologic features include dense cellularity, small round polygonal cells, and areas of calcification and necrosis. An abnormal pupil reflex (leukokoria); NYSTAGMUS, PATHOLOGIC; STRABISMUS; and visual loss represent common clinical characteristics of this condition.

Surgery is a technology consisting of a physical intervention on tissues. All forms of surgery are considered invasive procedures; so-called "noninvasive surgery" usually refers to an excision that does not penetrate the structure being exci...
