The Role Of Surgical Resection

Brain metastases in HER2+ breast cancer

With improved OS of patients with metastatic BC, including patients with BrM, there has been increased optimism and consideration of neurosurgical interventions. The primary indications for neurosurgical resection remain similar to other solid tumor histologies, including larger-sized metastases that may benefit from combined surgery and radiation treatment, relief of mass effect to facilitate improvement in functional status, and to facilitate tapering of corticosteroids. Among BC patients with a prolonged disease-free interval, histological confirmation of a brain lesion may be required. Additionally, surgery can enable definitive diagnosis of truly progressive disease vs radiation necrosis following treatment with CNS-directed radiation therapy.

Breast Cancers Survival Is Influenced By Tumor Grade

Grade identifies the size and shape of the malignant breast cancer cells. At the event the breast cancer cells look very different than normal breast tissue cells, and random in appearance, they can be called, that was badly differentiated and described as âhigh gradeâ. Higher level breast cancer cells tend to really have a poorer prognosis.

What Is Triple Negative Breast Cancer

A diagnosis of triple negative breast cancer means that the three most common types of receptors known to fuel most breast cancer growthestrogen, progesterone, and the HER-2/neu gene are not present in the cancer tumor. This means that the breast cancer cells have tested negative for hormone epidermal growth factor receptor 2 , estrogen receptors , and progesterone receptors .

Since the tumor cells lack the necessary receptors, common treatments like hormone therapy and drugs that target estrogen, progesterone, and HER-2 are ineffective. Using chemotherapy to treat triple negative breast cancer is still an effective option. In fact, triple negative breast cancer may respond even better to chemotherapy in the earlier stages than many other forms of cancer.

Screening: Pros And Cons

The topic of screening for brain lesions has become controversial in the field of breast cancer, mostly because of a lack of evidence. However, multiple studies in the works will attempt to disentangle the effects of regular brain MRIs on patients with breast cancer.

We dont have definitive data to say that screening is useful, and screening has the potential to be harmful if its done in a way that leads to treatment changes that may or may not be necessary, says Lin, who does not routinely screen patients but has a very low threshold for ordering a brain scan. People could end up getting treatments that they dont necessarily need or getting switched off the treatments that would otherwise have worked. Thats the argument against universal screening for brain metastases.

Hendron and Reece get regular brain MRIs to check for the appearance of new secondary tumors. In 2019, Hendrons doctors uncovered three more brain metastases, which were treated with stereotactic brain radiation therapy. Since then, her scans have been stable.

I often say cancer is a mind game. The body game is what the doctors and medicinedo, but the mind game is the work we have to do, she says. The biggest piece of advice is: You just have to learn to be present. All we have is this moment, and each person has to find what works for them to be in the moment.

The 5-year survival rate for women with metastatic breastcancer is 29%. With proper treatment and care, some women can live up to 10 years or more after diagnosis. Each patient is unique, however, and lifeexpectancy depends on factors such as overall health, response to treatment, and where the metastasis occurs.

Mechanisms Of Breast Cancer Metastasis

No one really knows what factors will make a certain patient more or less susceptible to breast cancer metastasis.

There is growing awareness that part of that susceptibility is due to host factors. The host factors are the characteristics of the non-malignant cells and the general biological environment surrounding the malignant breast tumor.

Sometimes the host factors are referred to as the pre-metastatic niche and it is thought that bone-marrow-derived progenitor cells may directly influence the dissemination of malignant cells to distant areas.

Non-neoplastichost cells within the tumor may also play a key role in the regulation of breast cancer metastasis.

Crosstalk Between Tumor And Brain Microenvironment

Breast cancer cells also adapt to the local microenvironment in the brain and co-opt neurons, astrocytes and microglial cells to proliferate and establish metastases.

Metastatic breast cells have been shown to develop neuronal characteristics, expressing the GABAA receptor, GABA transporter, GABA transaminase, parvalbumin, and reelin, allowing them to take up GABA, shunt it to nicotinamide adenine dinucleotide phosphate production and facilitate proliferation of the tumor cells in the brain microenvironment . Kim et al. showed that murine astrocytes co-cultured in direct cell-to-cell contact with human breast cancer cells caused up-regulation of survival genes in the tumor cells, thus protecting them from the toxic effects of chemotherapy.

Zhang et al. demonstrated that microRNAs from astrocytes cause human and mouse tumor cells with normal expression of PTEN, to downregulate PTEN expression in the brain environment. The loss of this tumor suppressor gene expression allows proliferation of brain metastases. Subsequent blockade of astrocyte secretion restored PTEN and suppressed brain metastasis in vivo. Loss of PTEN is associated TNBC subtype and portends a shorter survival time. Hohensee et al. showed that upregulation of PTEN in a TNBC cell line led to reduced migration and invasion to the brain. Autocrine and paracrine activation of GM-CSF/CSF2RA and AKT/PTEN pathway on both astrocytes and tumor cells mediated this crosstalk.

H& o What Is The Most Common Cause Of Death In Patients Who Have Breast Cancer That Has Metastasized To The Brain

CA The answer to that depends on the status of the extracranial disease and on the histologic subtype. For example, women with HER2-positive breast cancerwho receive targeted agents that do not treat the brainare more likely to experience a neurologic death. A woman with triple-negative breast cancer is more likely to develop metastases to both the lung and the brain, so in many cases it is uncontrolled extracranial metastases that lead to death. Of course, it can be difficult to determineeven at the patients bedsidethe precise source of a patients decline as the disease progresses overall.

Factors Affecting Survival After Brain Metastasis

Brain Metastases in HER2-Positive Breast Cancer

Univariate analysis showed that molecular subtypes, whether to undergo surgery and whole brain radiotherapy were significant prognostic factors affecting SABM . Multivariate analysis showed that SABM in triple-negative patients was significantly shorter than that in luminal type, but there was no statistical difference in SABM between HER2-positive and luminal patients. In addition, univariate and multivariate analysis suggested that surgical resection and WBRT were independent factors of SABM.

H& o How Has Our Understanding And Management Of Brain Metastases Changed Over The Past5 Years

CA We are seeing advances in both local and systemic therapy. The ability of neurosurgeons to locate and resect brain metastases has improved, and radiation oncology has improved as well. Traditional radiation treatment of brain metastases involved whole-brain radiation therapy, which includes low doses of radiation to the brain over the course of approximately 10 to 15 days. This approach irradiates a large amount of normal brain in addition to the brain metastases, which can lead to a decline in neurocognition and performance status.

More recently, the use of stereotactic radiosurgery has revolutionized the care of patients with brain metastases who have a limited number of lesionsusually no more than four. With stereotactic radiosurgery, the radiation oncologist delivers beams of high-dose radiation to tumors with extreme accuracy over 1 or 2 days, so that the remainder of the brain remains untouched by radiation.

When stereotactic radiotherapy is not possible, another option is whole-brain radiation. Newer strategies spare the hippocampus, the region of the brain that is our seat of memory. We have seen some very promising clinical trial results with hippocampus-sparing whole-brain radiation to preserve neurocognitive function.

Study Participants Had Metastatic Or Inoperable Breast Cancer

The clinical trial, called DESTINY-Breast04, enrolled 557 adults who had metastatic or inoperable HER2-low breast cancer and had previously been treated with one or two types of chemotherapy. Nearly 90% of participants had hormone receptorpositive disease, meaning their tumors had receptors for the hormones estrogen and/or progesterone. The trial was funded by the developers of T-DXd, Daiichi Sankyo and AstraZeneca.

Two-thirds of participants were randomly assigned to receive T-DXd and the rest to receive their doctors choice of chemotherapy. T-DXd was given intravenously every 3 weeks and patients were followed for a median of about 18 months.

In the group that received T-DXd, the median time that people lived without their cancer getting worse was about 10 months, compared with 5 months in the chemotherapy group. People who received T-DXd survived for a median of 23.4 months overall, while those in the chemotherapy group survived for a median of 16.8 months.

The numbers were similar when the researchers looked specifically at study participants who had hormone receptorpositive disease.

What Is Metastatic Breast Cancer


Metastatic breast cancer is also called stage IV or advanced breast cancer, in which the cancer has spread beyond the breast and adjacent lymph nodes to other parts of the body such as the bones, lungs, liver, or brain.

Remote recurrence occurs when metastatic breast cancer develops months or years after a person has finished therapy for early or locally advanced breast cancer.

Only 6% of women and 9% of men in the U.S. are diagnosed with de novo metastatic breast cancer, which refers to breast cancer that is already metastatic at the time of diagnosis.

Factors Associated With More Rapid Spread

Some types of breast cancer, as well as molecular subtypes, are more likely to spread and spread earlier than other types. Ductal carcinoma is more likely to spread than lobular carcinoma, among tumors that are the same size and stage.

While many breast cancers do not spread to lymph nodes until the tumor is at least 2 cm to 3 cm in diameter, some types may spread very early, even when a tumor is less than 1 cm in size.

H& o Could You Talk More About The Brain Metastases Specialty Clinic At Your Institution

CA Managing care for patients with brain metastases is very difficult, which is why we set up a coordinated, multidisciplinary clinic. These patients have issues that need to be addressed quickly by physicians in multiple specialties, including radiation oncology, neurosurgery, and medical oncology. Having the clinic means that patients do not have to wait a week for an appointment with a particular specialist, or travel throughout the hospital or to different locations to address their concernssomething that can pose a particular challenge for someone in fragile health. I would encourage other hospitals to set up similar clinics we spelled out our approach in the piece with Megan McKee as the first author.

Dont Count Yourself Out: Karens Cancer Immunotherapy Story

Treatment may involve local therapies directed at the brain metastases, such as surgery and radiation therapy, as well as systemic therapies that treat cancer throughout the body. Surgery could be a viable option for a single, large brain tumor, depending on its location. But for most patients, initial treatment involves either focused radiation or whole brain radiation, depending on the number of metastases and how early diagnosis occurs.

Because she had a single tumor, Hendron had a noninvasive procedure in February 2008 called Gamma Knife stereotactic radiosurgery, which uses 3D imaging to deliver a powerful, precise dose of radiation to a targeted area. It took just a single outpatient session without any incisions or anesthesia to successfully treat her lesion. Side effects of stereotactic radiosurgery can include fatigue, swelling, headache, nausea and vomiting and usually last for a few weeks after treatment.

Gamma Knife was the easiest treatment I ever had and the most effective, Hendron says. I was in the hospital at 7 a.m. and home by 11 a.m. I wore my own clothes and didnt need any pre-meds or post-meds.

Treatment has not been good to me. It has been a struggle really, really tough, Reece says. The side effects from the whole brain radiation were bad. I was nauseous, throwing up, dizzy.

Optimal Radiation Therapy Approaches

In terms of combined systemic therapy and radiation, prior studies have failed to demonstrate the benefit of combining WBRT with concurrent systemic agents including temozolomide and lapatinib. The results of the randomized phase II trial of WBRT with or without concurrent lapatinib , reported at the 2020 Society for Neuro-Oncology Virtual Meeting, revealed that while concurrent lapatinib improved the 4-week response rate, it did not improve the 12-week complete response rate, which was the primary endpoint of the trial. After limited toxicity in a phase I study of veliparib in combination with WBRT for BrM, with a large proportion of enrolled patients with BC, there is an ongoing phase IIb randomized, controlled trial to investigate whether there is a benefit in nonsmall-cell lung cancer however, BCBrM has not been evaluated. A recent systematic review has reported that the combination of lapatinib and SRS in patients with HER2+ BCBrM resulted in better local control and survival. Given the growing role of SRS in the management of BCBrM, further studies of the combination of SRS with novel agents are needed to guide optimized combination therapies moving forward.

Treatment For Brain Metastasis

Metastatic breast cancer in any part of the body is usually treated with systemic medicines, which treat cancer throughout the entire body. For brain metastasis, local treatments that specifically target the brain, such as surgery or radiation, are sometimes recommended.

Still, treating brain metastases can be challenging because of the blood-brain barrier. The blood-brain barrier is network of blood vessels and tissue that helps keep harmful substances from reaching the brain. The blood-brain barrier lets some things, such as water, oxygen, carbon dioxide, and general anesthetics, pass into the brain. But it also keeps out bacteria and other substances, including many medicines used to treat cancer.

While some chemotherapy medicines can help treat brain metastases, many chemotherapy medicines can’t cross the blood-brain barrier. Doctors often combine chemotherapy with targeted therapies, which are medicines that target specific characteristics of cancer cells.

Targeted therapies are treatments that target specific characteristics of cancer cells, such as a protein that allows the cancer cells to grow in a rapid or abnormal way. Targeted therapies are generally less likely than chemotherapy to harm normal, healthy cells. Some targeted therapies are antibodies that work like the antibodies made naturally by our immune systems. Because of this, they are sometimes called immune-targeted therapies.

The goals of local treatment depend on your specific situation:
