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.

• Modiﬁed skin appendage. • terminal duct lobular unit. Structure of the Terminal Ductal Lobular Unit (TDLU) The adult gland forms a tree-like structure starting at the nipple and branching through the stroma to end in lobules. The lobules are the ultimate milk producing functional units of the breast. The milk is expulsed through the intra-lobular terminal ducts and the extra-lobular terminal ducts The lobules and acini of the terminal duct-lobular unit (TDLU), the basic functional unit of the breast, may become distorted and undergo expansion due to the abnormal proliferation of cells comprising the structure. These changes represent a spectrum of atypical epithelial lesions that are broadly referred to as lobular neoplasia (LN).

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.

Terminal duct lobular units are scarce in the nipple: implications for prophylactic nipple-sparing mastectomy: terminal duct lobular units in the nipple.

Background: Nipple sparing mastectomy is widely used for both treatment and risk reduction of breast cancer. Terminal duct lobular units (TDLU) are considered as the basic reacting unit in all neoplastic lesions arising from the breast. TDLU is the basic anatomic unit of breast parenchyma, studies revealed that it also exists in the nipple whose frequency is not widely researched.

Occult neoplastic epithelial proliferation was seen in 5% of grossly/clinically unremarkable therapeutic mastectomy nipples. Pagetoid extension was the dominant spread of underlying malignancy. … 2017-05-25 · BACKGROUND: Terminal duct lobular unit (TDLU) involution is a physiological process of breast tissue aging characterized by a reduction in the epithelial component. In studies of women with benign breast disease, researchers have found that age-matched women with lower levels of TDLU involution are at increased risk of developing breast cancer. 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, C and D). Terminal duct lobular units (TDLUs) are the structures within the breast that produce milk and the primary source of most breast cancer precursors and cancers .

by AcronymAndSlang.com The glandular tissue consists of the lactiferous ducts and the so-called terminal ductal-lobular units (TDLUs), which are the morphological and functional unit of the Terminal duct lobular units (TDLUs) are the predominant source of future breast cancers, and lack of TDLU involution (higher. TDLU counts, higher acini count Apr 15, 2020 Abstract. Terminal duct lobular unit (TDLU) involution is the regression of milk- producing structures in the breast.

Background: Manual qualitative and quantitative measures of terminal duct lobular unit (TDLU) involution were previously reported to be inversely associated with breast cancer risk. We developed and applied a deep learning method to yield quantitative measures of TDLU involution in normal breast tissue.

The terminal ductal lobular units (TDLUs) are the functional units of the breast. The TDLU consists of the extralobular terminal ducts and intralobular terminal ducts. The intralobular terminal ducts form the central space of the lobule and have multiple outpouchings called acini or ductules.

Women with less TDLU involution are more likely to develop breast cancer. A major bottleneck in studying TDLU involution in large cohort studies is the need for labor-intensive manual assessment of TDLUs. We developed a computational pathology solution to automatically capture TDLU Terminal duct lobular units (TDLUs) are the structures within the breast that produce milk and the primary source of most breast cancer precursors and cancers .
