Surgical ovarian suppression for adjuvant treatment in hormone receptor positive breast cancer in premenopausal patients

OOPHORECTOMY: When and Why? A Novel Risk Stratification Tool as an Aid to Decision Making at Gynecological Surgeries

The decision regarding oophorectomy during gynecological surgeries, especially in perimenopausal and postmenopausal women, has historically posed a significant dilemma. Traditionally, it was widely believed that conserving the ovaries held no benefits, leading to a common practice of recommending bilateral salpingo-oophorectomy alongside hysterectomy for benign conditions in women aged 40-45 and above. Given our evolving comprehension of postmenopausal ovarian function and the genetic susceptibility to ovarian epithelial cancers, the decision regarding oophorectomy poses a dilemma. Oophorectomy is recommended for women with a higher risk of ovarian cancer and ovarian conservation is necessary with women with higher risk of co-morbidities. This paper reviews the available literature on these aspects of oophorectomy. Despite a wealth of literature narrating the advantages and disadvantages of oophorectomy, covering various aspects such as ovarian cancer risk, myocardial infarction incidence, and post-oophorectomy peritoneal cancer, there is a notable absence of a comprehensive evaluation system for risk stratification. The objective of the present paper is to address this gap by consolidating existing literature into a risk stratification system. This system will provide treating physicians a tool that facilitates more informed, case-specific decisions in collaboration with patients and their families. While recognizing that the ultimate decision must be tailored to the individual case and agreed upon mutually by the surgeon, patient, and family, the proposed system seeks to streamline risk stratification. This, in turn, should aid in determining the most suitable course of treatment that maximizes benefits for the patient.

Appraising Adjuvant Endocrine Therapy in Hormone Receptor Positive HER2-Negative Breast Cancer—A Literature Review

Background: Approximately 75% of breast cancer (BC) is associated with luminal differentiation expressing endocrine receptors (ER). For ER+ HER2− tumors, adjuvant endocrine therapy (ET) is the cornerstone treatment. Although relapse events steadily continue, the ET benefits translate to dramatically lengthen life expectancy with bearable side-effects. This review of ER+ HER2− female BC outlines suitable adjuvant treatment strategies to help guide clinical decision making around appropriate therapy. Methods: A literature search was conducted in Embase, Medline, and the Cochrane Libraries, using ER+ HER−, ET BC keywords. Results: In low-risk patients: five years of ET is the standard option. While Tamoxifen remains the preferred selection for premenopausal women, AI is the choice for postmenopausal patients. In the high-risk category: ET plus/minus OFS with two years of Abemaciclib is recommended. Although extended ET for a total of ten years is an alternative, the optimal AI duration is undetermined; nevertheless an additional two to three years beyond the initial five years may be sufficient. In this postmenopausal group, bisphosphonate is endorsed. Conclusions: Classifying the risk category assists in deciding the treatment route and its optimal duration. Tailoring the breadth of ET hinges on a wide array of factors to be appraised for each individualized case, including weighing its benefits and harms.
