Are both distinct epithelial and stromal cells molecular analysis from phyllodes tumors versus fibroadenoma components affected in breast fibroepithelial progression?

Acta cir. bras; 38 (), 2023
Purpose: To determine molecular events involved in the tumorigenesis of phyllodes tumors (PT) and the role of each stromal (SC) and epithelial (EC) cell. Methods: Frozen breast samples enriched with epithelial and stromal cells from three fibroadenomas and 14 PT were retrieved and laser microdissected. ...

An easy and practical prognostic parameter: tumor-stroma ratio in Luminal, Her2, and triple-negative breast cancers

SUMMARY OBJECTIVE: The stroma surrounding the tumor cells is important in tumor progression and treatment resistance, besides the properties of tumor cells. Studies on the tumor stroma characteristics will contribute to the knowledge for new treatment approaches. METHODS: A total of 363 breast cancer p...

Expression of stromal elements of prostatic adenocarcinoma in different gleason scores

Acta cir. bras; 34 (10), 2019
Abstract Purpose: To quantify and compare the expression of stromal elements in prostate adenocarcinoma of different Gleason scores with non-tumor area (control). Methods: We obtained 132 specimens from samples of prostate peripheral and transition zone. We analyzed the following elements of the extrac...

Prostate specific antigen and acinar density: a new dimension, the "Prostatocrit"

Int. braz. j. urol; 43 (2), 2017
ABSTRACT Background Prostate-specific antigen densities have limited success in diagnosing prostate cancer. We emphasise the importance of the peripheral zone when considered with its cellular constituents, the “prostatocrit”. Objective Using zonal volumes and asymmetry of glandular acini...

Gastrointestinal stromal tumors treated at a Brazilian Cancer Center: evaluation of clinical, epidemiological, and therapeutic profiles

Appl. cancer res; 37 (), 2017
Background: Gastrointestinal stromal tumors (GISTs) originate as precursor cells of the interstitial cells of Cajal in the myenteric plexus and generally have a mutation in the tyrosine kinase receptor, C-KIT (CD117). The objective is to evaluate the clinical, epidemiological, and therapeutic profiles of...

Adipose tissue stromal vascular fraction in the treatment of full thickness burns in rats

Acta cir. bras; 31 (9), 2016
ABSTRACT PURPOSE: To analyze the healing effects of stromal vascular fraction (SVF) application compared to wound dressing with 2% silver sulfadiazine in full thickness burn wounds in rats.
