Background: Carcinoma breast is ever-evolving and becoming increasingly prevalent in India. Numerous prognostic factors based on morphology and immunohistochemistry (IHC) have been established which need to be interconnected to give patients best possible treatment.
Aims: This study aims to confirm and analyze lymphovascular invasion (LVI) detected by hematoxylin and eosin (H and E) using IHC with CD34 and D2-40 and its correlation with other biologic and morphologic prognostic markers.
Settings And Design: This was a prospective study.
Materials And Methods: Fifty mastectomy specimens diagnosed as infiltrating ductal carcinoma breast on histopathology selected for the study. Evaluation of formalin-fixed paraffin-embedded sections was done using H and E and IHC for estrogen receptor (ER), progesterone receptor (PR), human epidermal growth factor receptor 2 HER2/neu receptors, CD34, and D2-40 endothelial markers. Correlation of LVI done with prognostic markers of Carcinoma Breast, namely, age of the patient, tumor size, Nottingham grade, lymph node ratio (LNR), Nottingham prognostic index (NPI), ER/PR status, and HER2/neu status. CD34 and D2-40 utilized to distinguish blood vessel, lymph vessel, and retraction artifacts and to calculate lymphatic microvessel density (LMVD) and blood microvessel density (BMVD).
Statistical Analysis Used: SPSS Software Package.
Results: LVI was associated with younger age (P = 0.001), greater tumor size (P = 0.007), higher Nottingham grade (P = 0.001), higher LNR (P = 0.001), higher NPI (P = 0.001), Negative ER Status (P = 0.001), Negative PR Status (P = 0.002), Positive HER2/neu status (P = 0.021), Higher Intratumoral BMVD (P = 0.016), Peritumoral BMVD (P = 0.001), and Intratumoral LMVD (P = 0.009). Blood vessels more commonly invaded than lymph vessels. Retraction artifacts can be mistaken for LVI without IHC.
Conclusions: D2-40 is a promising marker for lymphatic endothelium. LVI is a poor prognostic marker hence should be evaluated imperatively in all cases of carcinoma breast.

Objective: Cancer-related fatigue is one of the most common burdens of cancer patients. To date, most studies focused on fatigue during or after treatment. However, investigation of pretreatment fatigue is crucial to identify causal or risk factors other than cancer therapy and to enable timely fatigue management.

Breast cancer continues to be a major health issue for women worldwide, with vimentin (VIM) identified as a crucial factor in its progression due to its role in cell migration and the epithelial-to-mesenchymal transition (EMT). This study focuses on elucidating VIM's regulatory mechanisms on the miR-615-3p/PICK1 axis. Utilizing the 4T1 breast cancer cell model, we first used RNA-seq and proteomics to investigate the changes in the APA of PICK1 following VIM knockout (KO).

Cold atmospheric plasma (CAP) has been proposed as an emerging onco-therapeutics that can specifically kill cancer cells without harming healthy cells. Here we explore its potency in triggering ferroptosis in transformed cells using triple negative breast cancer as the disease model. Through the whole transcriptome sequencing, mass spectrometry analysis, point mutation, and a series of and molecular assays, we identified two signaling axes centered at EGFR(Y1068), i.

Occult breast cancer (OBC) is a relatively rare clinical condition that can complicate differential diagnosis efforts and delay the administration of specific treatments. The individualized therapy of patients with OBC should be performed based on their clinical symptoms, imaging findings and pathological diagnosis. The present case study describes a 51-year-old woman with a painless left axillary tumor.

Hypercalcemia is an identified complication of several malignancies and can cause significant adverse events. It is usually associated with cancers of the breast, lung (especially squamous cell), renal cell carcinoma, and multiple myeloma. Here, we present a rare case of esophageal adenocarcinoma presenting with hypercalcemia.
