Menopause drug may reduce breast cancer growth in postmenopausal women, study finds

A menopause drug commonly used to relieve symptoms such as hot flushes may also help slow the growth of breast cancer cells in postmenopausal women, according to new clinical trial results.
The phase two trial, led by researchers at Northwestern University, found that Duavee—a medication prescribed for menopause-related symptoms—appeared to reduce cell growth in the breast tissue of women diagnosed with ductal carcinoma in situ (DCIS), a non-invasive form of breast cancer that remains within the milk ducts.
Almost 60,000 women are diagnosed with DCIS each year. While the condition is not invasive, it can indicate a higher risk of developing invasive tumours later in life.
In the study, 141 postmenopausal women with DCIS were recruited. Half received Duavee and the other half were given a placebo for the month between diagnosis and breast cancer surgery.
DCIS is most often detected during routine mammograms, makes up around 25 per cent of all breast cancer diagnoses, and has a 98 per cent recovery rate at 10 years when removed by surgery.
To reduce the risk of recurrence, many patients also undergo treatments such as radiation or hormone therapy following surgery—both of which can lead to significant side effects.
Duavee is a combination of oestrogen and bazedoxifene, a selective oestrogen receptor modulator (SERM) that either enhances or blocks the effects of oestrogen depending on the type of tissue. It is also used to treat osteoporosis.
Those who took Duavee showed notably less cell growth in their breast tissue by the time of surgery, and researchers reported “no impact on quality of life compared to placebo.”
Dr Swati Kulkarni is a surgeon at Northwestern University and lead investigator of the trial.
Kulkarni said: “What excites me most is that a medication designed to help women feel better during menopause may also reduce their risk of invasive breast cancer.
Importantly, participants taking Duavee did not experience the intolerable side effects often associated with cancer drugs.
Instead, the medication tended to improve quality of life in women already dealing with menopause symptoms such as night sweats and hot flushes.
Although larger studies are still needed to confirm whether Duavee can prevent invasive breast cancer, the researchers suggest that it could offer benefits to women with an elevated risk of breast cancer who also suffer from menopause-related symptoms.
This is especially significant because women with a history of cancer lesions are typically advised not to use hormone replacement therapy to relieve menopause symptoms, due to the potential risk of cancer returning.
The researchers concluded: “These results support consideration that Duavee is a safe option to manage menopausal symptoms for women concerned about their risk of developing breast cancer.
“They also provide supportive evidence that Duavee may reduce the risk of developing invasive breast cancer.”
The trial results have not yet been published in a peer-reviewed journal but were presented at the American Society of Clinical Oncology’s latest annual meeting.

Endometriosis documentary profiles stars including Marilyn Monroe and Amy Schumer

A non-profit has launched an endometriosis documentary featuring Amy Schumer and Marilyn Monroe as it pushes for changes in how the condition is treated and understood.
The Endometriosis Collective has launched to change how endometriosis is researched, treated and understood, starting with a documentary featuring stories from people including Amy Schumer and Marilyn Monroe.
The feature-length documentary, “End of the Cycle”, will premiere in New York on Tuesday, and The Endometriosis Collective is making the film free to stream online.
Schumer, a comedian, writer and actor, has previously spoken of how endometriosis left her “on the floor in pain, vomiting from the pain, the pain that nobody can see.”
Schumer is one of several celebrities featured in the documentary. Other contributors include dancer Julianne Hough, Olympic medallist Brittany Brown and actors Janel Parrish and Folake Olowofoyeku.
The Endometriosis Collective timed the documentary premiere to coincide with the 100th anniversary of Marilyn Monroe’s birth.
Monroe, who died in 1962, starred in films such as “Some Like It Hot” and “Gentlemen Prefer Blondes.”
According to a biography published in 1985, Monroe’s endometriosis was so severe that it destroyed her marriages, her wish for children, her career and ultimately her life.
The Endometriosis Collective said the documentary shares newly uncovered information about Monroe’s experience with endometriosis.
The non-profit said the information connects Monroe’s story to the experiences of women across generations, highlighting how far awareness, research and care still have to go.
A representative of the Marilyn Monroe Estate said: “By sharing this part of her story through ‘End of the Cycle,’ we hope to honour her legacy in a way that brings visibility to endometriosis, encourages more open dialogue and helps inspire the research needed to create change.”
As part of the premiere, The Endometriosis Collective is holding a panel discussion.
Schumer, Brown and Olowofoyeku, the documentary’s co-directors Sammy Jaye and Soraya Simi, and medical experts are due to be part of the premiere.
AbbVie’s Orilissa and Sumitomo Pharma’s Myfembree are among the approved drugs for endometriosis pain.
Hough, one of the participants in the documentary, starred in an Orilissa campaign in 2017.
