What topics and trends defined most-cited Estrogen and related hormone effects research in the Class of 2026?
Research in the Class of 2026 centers on menopausal hormone therapy and targeted breast cancer care. Menopause and coronary heart disease risk saw major increases, while estradiol and selective estrogen receptor degraders gained momentum. Conversely, traditional aromatase inhibitors declined sharply as attention shifted toward novel combination therapies and precision cardiometabolic risk management.

Topic trends
Dominant research themes and year-over-year shifts in Estrogen and related hormone effects
What Topics Define the Class of 2026?
The Class of 2026 cohort in estrogen and related hormone research is driven by two major pillars: postmenopausal hormone therapy alongside women's cardiometabolic health, and targeted therapeutic strategies for hormone receptor-positive (HR+) advanced breast cancer. Menopause and menopausal hormone therapy (MHT) dominate the landscape, appearing in 28% and 18% of top-ranked publications respectively. High-impact investigations focus on clarifying long-term cardiovascular risks, cognitive function, and individual risk-benefit profiles associated with systemic MHT and estrogen monotherapy. Estradiol signaling and sex hormone-binding globulin (SHBG) emerge as key physiological biomarkers for metabolic and endocrine assessment in aging populations. In parallel, oncology research centers heavily on targeted interventions for advanced and HER2-negative breast cancer. Selective estrogen receptor degraders (SERDs), such as fulvestrant and novel oral agents, along with CDK4/6 inhibitors remain central clinical focal points. Studies evaluate combination regimens aimed at overcoming endocrine resistance, managing hot flashes, and tailoring risk stratifications for estrogen receptor-positive disease. Together, these focal points reflect a dual clinical focus: optimizing long-term systemic hormone safety during menopausal transitions while refining endocrine and targeted therapies for estrogen-driven malignancies.

How Did Topics Shift from the Class of 2025 to the Class of 2026?
Comparing the Class of 2025 to the Class of 2026 reveals significant thematic shifts in estrogen research, characterized by a surging interest in postmenopausal health outcomes and a strategic pivot in oncology therapeutics. The most prominent growth occurred in menopausal hormone therapy and postmenopausal risk assessment. Menopause research rose by 10 percentage points (from 18% to 28%), while coronary heart disease emerged sharply as a major focal area (reaching 10% of ranked literature from zero in the previous cohort). Estradiol evaluation (+6 percentage points) and breast cancer risk modeling (+8 percentage points) also recorded strong upward momentum, driven by large-scale clinical trials and colocalization analyses examining systemic hormone exposure. Conversely, traditional monotherapies and older treatment frameworks experienced noticeable declines. Aromatase inhibitors saw the steepest drop, falling from 18% in 2025 down to 6% in 2026 (-12 percentage points), reflecting a transition toward next-generation combination therapies. Generic hormone receptor-positive breast cancer classifications also contracted as studies adopted more granular molecular subtyping, such as HER2-negative and ESR1-mutated designations. These shifts highlight a field broadening its scope beyond localized tumor suppression toward comprehensive cardiovascular risk management, precision risk stratification, and novel SERD-based therapeutic regimens.

Methodology
PRI identifies high-impact research using a transparent, topic-agnostic framework applied consistently across scientific domains. Bibliographic records are drawn from OpenAlex, including publication dates, citation relationships, and document types.
This ranking covers the Class of 2026 cohort: journal articles published in 2024. Reviews and other non-article document types are excluded to ensure comparability.
Research impact is quantified with an 18-month post-publication citation window—the number of citing works published within 18 months of each paper's publication date. This metric captures early impact while controlling for publication age.
An LLM-based relevance classifier then reviews each candidate's title and abstract to confirm substantive alignment with the target domain. Only papers classified as relevant appear in the final ranking.
