Cervical Metastasis From Primary Breast Carcinoma: A Case Report and Review of Extragenital Tumors Involving the Uterine Cervix

open access: yesClinical Case Reports, Volume 14, Issue 7, July 2026.
ABSTRACT Cervical metastases from breast carcinoma should be considered in the differential diagnosis of uterine lesions in patients with prior breast cancer. Re‐biopsy is essential to detect receptor discordance (ER/PR up to 29%) and guide therapy. GCDFP‐15, mammaglobin, and GATA3 confirm mammary origin.

Hormonal, follicular and endometrial dynamics in letrozole-treated versus natural cycles in patients undergoing controlled ovarian stimulation

open access: yesReproductive Biology and Endocrinology, 2011
The objective of this study was to compare letrozole-stimulated cycles to natural cycles in 208 patients undergoing intrauterine insemination (IUI) between July of 2004 and January of 2007. Group I (n = 47) received cycle monitoring only (natural group),

Optimal model‐based design of experiments for parameter precision: Supercritical extraction case

open access: yesThe Canadian Journal of Chemical Engineering, Volume 104, Issue 7, Page 3775-3795, July 2026.
Abstract This study investigates the process of chamomile oil extraction from flowers. A parameter‐distributed model consisting of a set of partial differential equations is used to describe the governing mass transfer phenomena in a cylindrical packed bed with solid chamomile particles under supercritical conditions using carbon dioxide as a solvent ...

GP88 (PC-Cell Derived Growth Factor, progranulin) stimulates proliferation and confers letrozole resistance to aromatase overexpressing breast cancer cells

open access: yesBMC Cancer, 2011
Background Aromatase inhibitors (AI) that inhibit breast cancer cell growth by blocking estrogen synthesis have become the treatment of choice for post-menopausal women with estrogen receptor positive (ER+) breast cancer.

Efficacy and Safety of Controlled Ovarian Stimulation With or Without Letrozole Co-administration for Fertility Preservation: A Systematic Review and Meta-Analysis

open access: yesFrontiers in Oncology, 2020
Background: The co-administration of letrozole during controlled ovarian stimulation (COS) with gonadotropins is used to limit the potentially harmful effects of a supra-physiological rise in estrogen levels on hormone-sensitive cancers.
