Anastrozole has an association between degree of estrogen suppression and outcomes in early breast cancer and is a ligand for estrogen receptor α.
CONCLUSIONS: This matched case-control clinical study revealed that levels of estrone and estradiol above identified thresholds after six months of adjuvant anastrozole treatment were associated with increased risk of an EBCE. Preclinical laboratory studies revealed that anastrozole, but not exemestane or letrozole, is a ligand for estrogen receptor a. These findings represent potential steps towards individualized anastrozole therapy. PMID: 32098767 [PubMed - as supplied by publisher] (Source: Clinical Cancer Research)

Benign leiomyoma with multiple metastases to vertebrae and calvarium: An index case with comprehensive review of endocrine targets
Abstract“Benign” metastatic leiomyomas (BML) are indolently growing metastatic tumors which mostly associate with uterine leiomyomas in women in reproductive ages. The reason to define these lesions as “benign” despite metastasis is their pathological features with low mitotic counts, lack of or min imal nuclear atypia, pseudocyst formation, and coagulative necrosis unlike leiomyosarcomas. Despite lack of pathological malignant features, they may cause significant morbidity and even mortality. Here, we describe a BML case with metastases to vertebrae and skull bones. Vertebral and skull metasta ses ...

First-line endocrine therapy for postmenopausal patients with hormone receptor-positive, HER2-negative metastatic breast cancer: a systematic review and meta-analysis.
CONCLUSION: In the first-line treatment for advanced postmenopausal hormone receptor-positive breast cancer, a combination therapy of CDK4/6 inhibitors and AI showed significant improvement of PFS, ORR, and CBR but with significant increased toxicities compared with AI alone. Fulvestrant 500 mg monotherapy significantly prolonged PFS compared with AI monotherapy. We must wait for the results of the studies with longer follow-up period.

Anastrozole-Induced Dermatitis: Report of a Woman with an Anastrozole-Associated Dermatosis and a Review of Aromatase Inhibitor-Related Cutaneous Adverse Events
AbstractAnastrozole is an aromatase inhibitor. Anastrozole competitively inhibits the aromatase enzyme, which synthesizes estrogen. It is used for estrogen receptor-positive breast cancers. A woman with breast cancer and anastrozole-induced dermatitis is described; the cutaneous side effects associated with aromatase inhibitors are also reviewed. Skin-related adverse events associated with aromatase inhibitor use are uncommon and may be delayed in appearance; the time of onset ranges from less than 5 days to 6 months (median 2 months). They present as either vasculitis, erythema nodosum, subacute cutaneous ...

M166 estrogen-dependent angioedema responsive to anastrozole in a male with familial hyperestrogenemia and hereditary cancer risk
A 44-year-old man was evaluated for recurrent angioedema manifested as more than 10 discrete episodes with swelling of the posterior pharynx and uvula, without urticaria, that would subside spontaneously over 24 hours. These episodes were first noted 2 years ago, were worsened by alcohol, and were not responsive to antihistamines. Medical history was significant for hyperestrogenism, that worsened with testosterone treatment for infertility. His primary family history revealed a father and brother with gynecomastia, a mother with endometrial cancer, and a sister with Lynch syndrome. (Source: Annals of Allergy, Asthma and Immunology)

A systematic review and meta-analysis of clinical trials implementing aromatase inhibitors to treat male infertility.
Abstract Aromatase activity has commonly been associated with male infertility characterized by testicular dysfunction with low serum testosterone and/or testosterone to estradiol ratio. In this subset of patients, and particularly in those with hypogonadism, elevated levels of circulating estradiol may establish a negative feedback on the hypothalamic-pituitary-testicular axis by suppressing follicle-stimulating hormone (FSH) and luteinizing hormone (LH) production and impaired spermatogenesis. Hormonal manipulation via different agents such as selective estrogen modulators or aromatase inhibitors to increase end...

386TiPRIbociclib plus goserelin with hormonal therapy versus physician choice chemotherapy in premenopausal or perimenopausal patients with HR+, HER2 – inoperable locally advanced or metastatic breast cancer: RIGHT choice study
AbstractBackgroundA high percentage of breast cancer patients in the Asia-Pacific ( ∼42%) and Middle East (∼50%) regions are aged 50 years or younger. Although a high proportion of younger patients with endocrine-responsive metastatic disease are treated initially with cytotoxic chemotherapy (CT) in routine general practice, data from phase III trials have shown higher response rates and longer progression-free survival with endocrine therapy (ET) in combination with CDK4/6 inhibitor versus single agent ET. Due to lack of direct evidence, trials in pre-/perimenopausal advanced breast cancer are thus necessary to as...

A novel GC-MS methodology to evaluate aromatase activity in human placental microsomes: a comparative study with the standard radiometric assay.
Abstract Estrogens are key factors in the development of the estrogen receptor-positive (ER+) breast cancer. Estrogens, estrone (E1), and estradiol (E2) production is achieved by aromatase, a cytochrome P450 enzyme that has androgens, androstenedione (AD), and testosterone (T) as substrates. Nowadays, third-generation aromatase inhibitors (AIs) are considered the gold-standard treatment for ER+ breast cancer in postmenopausal women as well as in premenopausal women with ovary ablation. Aromatase activity assessment still relies on radiometric assays that are expensive, hazardous, and non-environmentally friendly. ...

Efficacy of denosumab for restoring normal bone mineral density in women receiving adjuvant aromatase inhibitors for early breast cancer
Background: Osteoporosis is a major side effect of aromatase inhibitors (AIs), which are greatly effective in the treatment of breast cancer.

CONCLUSION: A subset of asymptomatic patients with ER⁺ and/or PR⁺ ROC and CA125 progression had durable clinical benefit on anastrozole, with acceptable toxicity. Anastrozole may delay symptomatic progression and the time to subsequent chemotherapy. The future challenge is to identify the subset of patients most likely to benefit from an aromatase inhibitor and whether the clinical benefit could be increased by the addition of other agents.

Effect of local aromatase inhibition in endometriosis using a new chick embryo chorioallantoic membrane model.
Abstract Endometriosis is an oestrogen-dependent, inflammation-driven gynaecologic disorder causing severe disability. Endometriosis implants are characterized by unbalanced local oestrogen metabolism leading to hyperoestrogenism and aromatase up-regulation is one of main mechanism involved. Aromatase inhibitors such as letrozole or anastrozole use in young women are associated with severely side effects limiting their long-term clinical use. An endometriosis-targeted inhibition of local aromatase could be a viable alternative, although the role of the local inhibition of this enzyme is still unclear. Using a new ...

Kaplan-Meier method was used to generate time-to-event curves and estimate median progression-free survival (mPFS). Log-rank test was used to compare differences. Results: A total of 200 patients, with a median age of 59.4 years and a follow-up of 19.5 months, were included. Palbociclib was most frequentl...
