Fine-needle cytological characteristics of carcinoma breast with medullary or medullary-like features masquerading as dendritic reticulum cell sarcoma: An attempt to explore the reasons for erroneous cytologic interpretation

open access: yesJournal of Cytology, 2020
Background: Infiltration of tumors by dendritic reticulum cells (DRC) reflects the host immune defense mechanism. We observed three breast carcinomas cases with dense tumor-infiltrating DRC and lymphocytes in fine-needle aspiration (FNA) smears, leading ...

A Population-Based Study of Genes Previously Implicated in Breast Cancer.

open access: yesNew England Journal of Medicine, 2021
BACKGROUND Population-based estimates of the risk of breast cancer associated with germline pathogenic variants in cancer-predisposition genes are critically needed for risk assessment and management in women with inherited pathogenic variants ...

Evolutionary interplay between viruses and R‐loops

open access: yesFEBS Letters, EarlyView.
Viruses interact with specialized nucleic acid structures called R‐loops to influence host transcription, epigenetic states, latency, and immune evasion. This Perspective examines the roles of R‐loops in viral replication, integration, and silencing, and how viruses co‐opt or avoid these structures.

The role of FNAC in diagnostically challenging malignant lesions of breast

open access: yesJournal of Dr. NTR University of Health Sciences, 2019
Background: Fine needle aspiration cytology is a simple investigation to evaluate the malignant tumors of the breast when compared to tru-cut biopsy. It is invaluable in the diagnosis of the common invasive carcinoma of the breast including its subtypes.

A rare case of intraductal papilloma with atypical ductal hyperplasia in a male breast: A pathological diagnosis

open access: yesJournal of Family and Community Medicine, 2020
Male breast cancer is itself a very rare condition and represents 0.5%–1% of all breast cancers diagnosed. Atypical ductal hyperplasia (ADH), intraductal papilloma (IP), and ductal carcinoma in situ are also very rare in a male breast.

Subpar reporting of pre‐analytical variables in RNA‐focused blood plasma studies

open access: yesMolecular Oncology, EarlyView.
Pre‐analytical variables strongly influence the analysis of extracellular RNA (cell‐free RNA; exRNA) derived from blood plasma. Their reporting is essential to allow interpretation and replication of results. By evaluating 200 exRNA studies, we pinpoint a lack of reporting pre‐analytical variables associated with blood collection, plasma preparation ...

Screening Mammography Breast Cancer Detection [PDF]

open access: yesarXiv, 2023
Breast cancer is a leading cause of cancer-related deaths, but current programs are expensive and prone to false positives, leading to unnecessary follow-up and patient anxiety. This paper proposes a solution to automated breast cancer detection, to improve the efficiency and accuracy of screening programs.
