Validity of the study of sentinel lymph nodes in the treatment of breast carcinoma.

2004

Since it was introduced in the 1990s, axillary sentinel lymph-node biopsy has been rapidly and widely adopted to avoid complete axillary dissection (though this is still the standard procedure). The aims of the study were two-fold: (i) to determine the value of different techniques of sentinel lymph-node identification and (ii) to verify the predictive value of such procedures through histological examination of the sentinel lymph node and axillary dissection in the same patients. Both sentinel lymph-node biopsy and axillary dissection were performed in 230 patients with T1 and T2 (< 3 cm) carcinoma of the breast. Preoperative lymphoscintigraphy was able to identify the sentinel lymph node …

Diagnostic accuracy of computed tomographic colonography for the detection of advanced neoplasia in individuals at increased risk of colorectal cance…

2009

CONTEXT: Computed tomographic (CT) colonography has been recognized as an alternative for colorectal cancer (CRC) screening in average-risk individuals, but less information is available on its performance in individuals at increased risk of CRC. OBJECTIVE: To assess the accuracy of CT colonography in detecting advanced colorectal neoplasia in asymptomatic individuals at increased risk of CRC using unblinded colonoscopy as the reference standard. DESIGN, SETTING, AND PARTICIPANTS: This was a multicenter, cross-sectional study. Individuals at increased risk of CRC due to either family history of advanced neoplasia in first-degree relatives, personal history of colorectal adenomas, or positiv…
