Palliative Care At Johns Hopkins

Brain metastases developed from HER2 postive and triple negative breast cancer

Palliative care is specialized medical care that helps patients facing serious illnesses and their families by adding an extra layer of support.

Palliative care teams can help with the symptoms and the stress of living with a serious illness, including controlling pain, providing support for the mental and emotional effects of an illness, and managing other symptoms.

Ongoing Trials And Future Prospects

Current trials include a focus on immunotherapy. From clinical trials in melanoma and lung cancer, we are aware that immunotherapy does have an impact on brain metastases. Hoping to unleash an abscopal effect using radiation in addition to immunotherapy, there are ongoing trials combining the two. Investigators are pursuing a phase II trial with the programmed death ligand 1 inhibitor atezolizumab in combination with SRS in TNBC with brain metastasis . Another phase II clinical trial is evaluating neratinib with capecitabine in HER2-positive patients. Subsequently, another arm in this trial has been added to include neratinib plus T-DM1 .

Some of the other noteworthy trials in HER2-positive disease include a phase II randomized controlled trial of a new oral HER2 inhibitor, tucatinib, in combination with trastuzumab and capecitabine . Some other interesting future prospects include phosphoinositide 3-kinase/mammalian target of rapamycin inhibitors and cyclin-dependent kinase 4/6 inhibitors.

Systematic Screening For The Detection Of Bm

Due to the lack of data demonstrating a clinical benefit, brain screening for patients with MBC is not currently recommended in the US NCCN and ESMO guidelines. Nevertheless, patients at high risk of developing BM could potentially benefit from screening strategies, as an earlier diagnosis could lead to a reduction in WBRT use and enable localised, less toxic and more effective BM treatment in a higher proportion of cases.,, Four studies are exploring the value of systematic radiological screening.

Metastatic Brain Cancer Treatment

It is important to know that metastatic brain tumors are often treatable, and can be well-controlled. Generally, the faster you start treatment, the better the chances of killing or controlling the disease.

The treatment options for brain metastases may include:

  • Clinical trials

In many cases, surgery or radiation therapy can improve or entirely get rid of symptoms. Read more about brain tumor treatment.

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.

Metastatic Brain Tumor Surgery

Surgery provides fast relief of mass effect pressure inside the skull resulting from a growing metastatic tumor and swelling of the brain. Some patients may find improvement of symptoms as early as within hours of surgery if mass effect is what is causing your symptoms.

The goal of surgery is to minimize the amount of space the tumor takes up by debulking, which means removing as much of the tumor as possible while maintaining neurological function.

In general, doctors recommend surgery for metastatic brain cancer when:

  • There is a clear link between the symptoms and the tumors location.
  • The primary cancer is treatable and under control.
  • The tumor can be safely removed.

The most common type of surgery to remove metastatic brain tumors is called a craniotomy, which can be performed through a variety of approaches, including the keyhole craniotomy.

Immunotherapy For Metastatic Brain Tumors

HER2 Breast Cancer: Brain Metastasis Prevalence & Later-Line Therapy

Cancer immunotherapy is a fast-growing field of research that seeks to develop drugs, vaccines and other therapies that trigger the immune systems natural abilities to fight cancer. Many immunotherapy drugs for metastatic brain tumors act as checkpoint inhibitors. Normally, tumor cells can evade attack by activating certain proteins that disarm your immune system. Checkpoint inhibitors prevent tumor cells from exploiting this process.

Immunotherapy drugs to treat metastatic brain tumors include:

Cns Screening For The Detection Of Brain Metastasis

Current NCCN guidelines do not recommend screening for brain metastasis due to a lack of clinical benefit. Dana-Farber Cancer Institute trial will look into this question and has divided that patient into four cohorts, out of which one cohort is TNBC, who will be undergoing screening by Magnetic Resonance Imaging .33 Another trial includes TNBC and HER2 positive patients in which MRI screening will be done in three instances – initial diagnosis and change of treatment after the first line and second line.34 Finally, we present a SYMPToM trial with 50 women with TNBC or HER-2 positive breast cancer randomized to either clinical surveillance or MRI screening every 4 months.35 All of these trials will help us in answering the question of routine CNS screening for advanced TNBC patients and potential benefits for initiating early local treatment and reduction of WBRT.36,37

On CT and MR we look for tissue characteristics like calcifications, fat, cystic components, contrast enhancement and signal intensity on T1WI, T2WI and DWI. Most brain tumors are of low signal intensity on T1WI and high on T2WI. Therefore high signal intensity on T1WI or low signal on T2WI can be an important clue to the diagnosis. Stereotactic radiosurgery for brain metastases. Radiation therapy uses high-energy beams, such as X-rays and protons, to kill tumor cells. For brain metastases, your treatment may involve one or both of the following radiation therapy methods: Whole-brain radiation. Whole-brain radiation applies radiation to the entire brain in order to kill.

Brain metastasis in metastatic breast cancer can be silent, and it is fairly common for patients to be asymptomatic. But mBC has substantial direct and indirect costs for patients, insurance payers, and society. The goals of therapy for mBC with brain metastasis are to improve symptoms, stabilize or reduce the tumor burden, maintain quality of life, and improve overall survival. New therapies can provide value by reducing the risk of distant metastasis, preventing central nervous system relapse, and improving quality of life. This article discusses the risk factors, comorbidities, diagnosis, economic burden, and treatments for brain metastasis in mBC, based on recent Insights video interviews with Kevin Kalinsky, MD, MS Sarah Sammons, MD and Bhavesh Shah, RPh, BCOP.

Randomized trials are lacking in this area and only low-level evidence exists in the form of case reports to support the activity of endocrine therapy in brain metastases. The overall incidence of brain metastasis in the hormone receptor positive subtype is much less frequent. Case report data suggest responses to tamoxifen and aromatase inhibition. Patients with HR positive brain metastases have shown significant responses to cytotoxic chemotherapy. Niwinska et al. demonstrated an improvement in the median survival ranging from 3-14 months with the addition of chemotherapy in luminal breast cancer subtypes. Therapy selection for brain metastases arising from HR positive breast cancer emphasizes local control followed by systemic chemotherapy or in select cases endocrine therapy if extracranial disease is stable.

How Do You Decide Which Metastatic Brain Cancer Treatment Is Right For You

Your neurosurgeon will discuss the most appropriate treatment approach with you by considering these and other factors:

  • The type of primary cancer, your response to treatment and current status
  • The location and number of metastatic tumors within the brain or spine
  • Your general health and preferences regarding potential treatment options
  • Your current symptoms

Along with benefits, doctors also consider the potential risks and side effects of any treatment. Many patients are worried about the effects of radiation. Others hesitate about the idea of surgery. Tell your doctor about your concerns they are important to consider.

Is The Brain The Most Common Place For Breast Cancer To Spread Or Are There Other Places In The Body That Are Equally Common

It can spread to nearby lymph nodes as well, but the brain is a very common place. First off, 20% of the body’s blood supply goes there, so the brain is a common place for a lot of cancers to spread. But one of the unique things about breast cancer when it goes to the brain and this was discovered at the CU Cancer Center is that breast cancer may metastasize more commonly to parts of the brain that are associated with higher estrogen activity.

Stereotactic Radiosurgery And Whole

Survival Advantage Observed in HER2 Breast Cancer With Brain Metastasis

Stereotactic radiosurgery or whole-brain radiation therapy can be used in addition or as an alternative to surgery. SRS is a minimally invasive ablative treatment option and is preferred over surgery for patients with small asymptomatic lesions that do not require surgery or lesions that are not surgically accessible.46

A retrospective study looked at 122 patients who underwent SRS for management of BM in different subtypes of breast cancer. The median number of lesions at the start of the treatment was 3. 21% of the patient were TNBC, 31% were ER+HER2 23% were ER+HER2+, and 18% were ERHER2+, and the median overall survival was found to be 7, 16, 26, and 23 months, respectively. Patients with TNBC had the shortest time to retreatment and the poorest survival. This shows that the benefit of SRS may not provide adequate control of BM, showing the need for developing more effective treatments.49

The NCCTG N0574 trial looked at the benefit of adding WBRT to SRS on cognition of patients with 13 brain metastases and found that there were higher rates of cognitive deterioration after WBRT even though there was better intracranial control.49 The rationale for using SRS alone without WBRT is further supported by the fact that studies have not shown survival benefit in this setting.

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.

Comparison Of The Subgroups

Metastatic dissemination differs among the various subtypes of breast cancer, a higher incidence of brain metastasis is seen in TNBC and Human Epidermal Growth Factor Receptor 2 -positive breast cancer, whereas metastasis to the lungs and bones is more common in Luminal subtypes.11,12

The incidence of brain metastasis in TNBC is approximately 2546%, a similar incidence was found in Metastatic Her2 positive breast cancer , a lower incidence of BM was noted in Luminal A and B . Thus, the risk of developing brain metastasis is 25 times higher in Her2 positive and TNBC cancers.17,18 With the advancement in breast cancer treatments in metastatic space, the number of patients developing brain metastasis appears to be increasing. A recent meta-analysis showed that approximately one-third of those with TNBC will eventually develop brain metastasis.19 A systematic review by Koniali et al identified younger age, hormonal and Her-2 receptor status, higher tumor stage and size, higher histological grade, high Ki67 labeling index as independent risk factors for Breast Cancer Brain Metastasis .20 Symptoms are variable and can be nausea, headaches, personality changes, seizures, paralysis, and cognitive impairment.21

How Are Metastatic Brain Tumors Diagnosed

Regression of brain metastases from breast cancer with eribulin: a case ...

Metastatic brain and spine tumors are not usually diagnosed until symptoms appear. Here are some ways doctors may diagnose a metastatic brain tumor:

  • Physical exam: After gathering information about your symptoms and personal and family health history, the doctor proceeds with a physical exam and vision and reflex tests.
  • Magnetic resonance imaging
  • Diffusion tensor imaging is a type of MRI that visualizes how water molecules pass through parts of the brain. It reveals microscopic differences of tissue structure, including very early infiltration of cancer cells.
  • Biopsy: Collecting a piece of the tumor through surgery may be necessary when the diagnosis is unclear based on the other tests.
