HER-2 negative + AR positive + ER positive

Our study suggests differential tamoxifen benefit by menopausal status. Improved long-term endocrine therapy prediction in premenopausal patients is needed and could involve molecular markers because standard tumor characteristics cannot predict benefit beyond 10 years.

Surgery was not possible due to comorbidities, so fulvestrant(500 mg/month)+denosumab(120 mg/month)was started. Furthermore, as the tumor markers were elevated, abemaciclib(300 mg/day)was added, which resulted in a decrease in the tumor markers...During the course of treatment, the tumor markers rose again, so the dose was increased to 250 mg/day, which resulted in a decrease in the tumor markers and good tolerability. At present, 36 months after the start of treatment, long SD has continued, no adverse events of grade 3 or higher have been observed, and the drug has been well tolerated.

We judged that both patients were at intermediate risk of recurrence and administered S-1 in addition to endocrine therapy. Even in cases without axillary lymph node metastasis, this combination of S-1 with endocrine therapy was considered to be a useful treatment option if the criteria of the POTENT trial were met.

Together, the results suggest that mRNA expression of ESR1, ESR2, and PGR might differ depending on menopausal status in breast tumors with certain receptor status. More importantly, the change in the expression of ESR1 and ESR2 following menopause is in the opposite directions in breast cancer patients showing the need to identify particular molecular mechanisms regulating the expression of ER isoforms post-menopause in different directions in breast cancer patients, considering the high clinical importance of these receptors in terms of the prognosis of patients with breast cancer.

Pts are randomized post-BCS to Arm 1 with breast RT using standard methods (moderate or ultra hypo- or conventional-fractionated whole breast RT with/without boost, or APBI) with ≥5 yrs of ET (tamoxifen or AI) or Arm 2 with ≥5 yrs of ET (tamoxifen or AI) alone...As of July 3, 2024, 1,033 pts have been screened and 927 randomly assigned. NCT #: NCT04852887.

Subsequently, he received androgen deprivation therapy (ADT) for 6 months with triptorelin and bicalutamide...The pathological stage was pT1c pN1mi.The Oncotype DX study had a Recurrence Score (RS) of 22 points, leading to a recommendation for adjuvant chemotherapy with Docetaxel-Cyclophosphamide for 4 cycles, followed by tamoxifen...Early detection through screening and appropriate medical follow-up improves the prognosis in patients carrying PV in BRCA2. Therefore, risk control monitoring and adequate genetic counseling are necessary.

Participants must not have received any prior treatment for their current breast cancer, including chemotherapy, immunotherapy, biologic, or hormonal therapy, and must be candidates for doxorubicin, paclitaxel, and durvalumab therapy. No participants are currently ineligible. There have been no Grade 4 or higher adverse events reported among the 26 participants assessed for adverse events.

This patient had a history of right ER/PR positive HER2 negative stage 1 breast cancer s/p lumpectomy with sentinel lymph node biopsy and radiation plus tamoxifen x6 months in 2017...No right-sided sentinel node was identified. The right breast lesions and the left axillary lymph node metastases are all morphologically similar and showed strong ER expression, the results of which are compatible with spreading to the contralateral axilla.

Treatment typically follows protocols for female breast cancer, including surgery, chemotherapy, and hormone therapy, with tamoxifen being commonly used. Further research is needed to better understand its pathogenesis and to develop more effective, tailored treatments.

Genetic testing of the excised tumor revealed a MUTYH gene mutation and a BARD1 (BRCA1-associated RING domain 1) gene mutation of unknown significance. Histopathological analysis confirmed a Grade 2, ER/PR-positive, KI 67-positive, and HER2-negative tumor.

Although tamoxifen therapy is an essential treatment, the long-term benefit for patients with luminal A and B subtype is not well understood. Secondary analysis of 952 ER-positive/HER2-negative patients with luminal A or B molecular subtype from the Stockholm Tamoxifen 2, 3 and 5 trials randomized to receive tamoxifen therapy (tamoxifen alone or with goserelin) or control. Our findings suggest a long-term benefit from tamoxifen for most patients with less aggressive tumor characteristics irrespective of molecular subtype, but the benefit differed by menopausal status. Luminal B patients with PR-positive, lymph node-negative or low genomic risk tumors had a higher risk as compared to patients with luminal A tumors.
