Terminal duct lobular unit was seen in 26% (17 of 65) of cases. Terminal duct lobular units are scarce in the nipple: implications for prophylactic nipple-sparing mastectomy: terminal duct lobular units in the nipple. Prevalence of terminal duct lobular units and frequency of neoplastic involvement of the nipple in …

Results of the acini detection (A), terminal duct lobular unit (B), and adipose tissue (C) segmentation algorithms. The original images are in the left column, the middle column shows ground truth as annotated by human observers, and the detections and segmentations performed by the automated method are displayed in the right column. What does Undefined TDLU stand for? Hop on to get the meaning of TDLU. The Undefined Acronym /Abbreviation/Slang TDLU means Terminal duct lobular unit.

Terminal duct lobular units (TDLUs) are the milk-producing structures of the breast and the predominant anatomical structures from which breast cancers originate1. Higher number of TDLUs and higher extralobar terminal duct (ETD) which attaches the lobule to the ductal system intralobar terminal duct (ITD) continues the duct system into the lobule clusters of 10-100 sac-like acini that open into the ITD. Acini and the terminal duct are the source of Involution of terminal duct lobular units (TDLUs), the structures that give rise to most breast cancers, has been associated with reduced breast cancer risk. Data suggest that the etiology and pathogenesis of luminal A and core basal phenotype (CBP) breast cancers differ, but associations with TDLU involution are unknown. International License. TDLU is a shorter form of terminal-duct-lobular-units. TDLU means terminal-duct-lobular-units. TDLU is an acronym for terminal-duct-lobular-units.

Occult neoplastic epithelial proliferations identified in 4 nipples (Table 1) included primary disease with 1 case of lobular carcinoma in situ involving TDLU in the nipple (Figure 2, A) and 1 case of Paget disease with lesion measuring 0.1 cm (Figure 2, B); and extension of underlying malignancy with 2 cases of pagetoid spread of spatially remote invasive ductal carcinoma (IDC) along lactiferous ducts (Figure 2, …

The intralobular terminal ducts form the central space of the lobule and have multiple outpouchings called acini or ductules. In the resting gland the terminal lobules are referred to as the Terminal Ductal Lobular Unit (TDLU). TDLUs can be classified according to their complexity.

A, Diagrammatic representation of this structure. ETD = Extralobular terminal duct; ITD = intralobular terminal duct. 2017-02-15 · Terminal duct lobular units (TDLUs) are the predominant source of future breast cancers, and lack of TDLU involution (higher TDLU counts, higher acini count per TDLU and the product of the two) is a breast cancer risk factor.

The terminal ductal lobular unit is an important structure because most invasive cancers arise from the TDLU.

We read with interest the recent article from Kensler and colleagues ([1][1]), “Automated measures of terminal duct lobular unit involution and breast cancer risk.” This article represents an important first effort to use computational quantitative methods to assess age-related involution of Extensive mammographic density (MD), a well‐established breast cancer risk factor, is a radiological representation of stromal and epithelial breast tissue content. In studies conducted predominantly among Caucasian women, histologic measures of reduced terminal duct lobular unit (TDLU) involution have been correlated with extensive MD, but independently associated with breast cancer risk Terminal duct lobular units (TDLU), the histologic structures of the breast that are responsible for lactation, are the predominant source of breast cancers (1).

Localization Breast carcinoma arises from the mammary epithelium mostly from the Terminal duct lobular unit (TDLU). Higher frequency of invasive breast cancer in the left breast with reported to left to right ratio of approximately 1.07 to 1. 40 to 50 % occurs in upper outer quadrant of the breast. English term or phrase: terminal duct lobular unit However, it has been shown that full term pregnancy induces differentiation of cells in the terminal duct lobular unit (TDLU) in the breast and this effect produces the long term effect of slowing the cell cycle in the epithelial cells of this location, which allows more time for DNA repair, which in turn will lead to decreased carcinogenesis Terminal duct lobular units (TDLU) are considered as the basic reacting unit in all neoplastic lesions arising from the breast.

linking involution of terminal duct lobular units (TDLU), the structures from which most breast cancers arise (3), and MD have provided important clues (4, 5). TDLU involution, a normal process of aging, is characterized by a reduction in the number and size of TDLUs and their secretory substructures called acini (3). Likewise, MD decreases
