Systemic Treatments for IBC

Inflammatory Breast Cancer requires an aggressive and coordinated treatment approach. The goal of treatment is to manage the disease effectively by reducing the tumor size, controlling its spread, and addressing cancer cells throughout the body. IBC typically begins with systemic treatments, followed by surgery and radiation, a strategy often referred to as “Trimodal Treatment.” However, your oncology team may also discuss with you the possibility of giving these treatments in different sequences.

Some patients will undergo chemotherapy-radiation at the same time depending on their presentation.

Understanding the Treatment Path
  1. Systemic Treatments: IBC often begins with systemic treatments such as chemotherapy, targeted therapies, and sometimes immunotherapy. These treatments work throughout the entire body to shrink the tumor and target cancer cells that may have spread beyond the breast.
  2. Surgery: After systemic treatment, surgery is usually the next step. The standard surgical procedure is a modified radical mastectomy with lymph node dissection, which removes the affected breast tissue and nearby lymph nodes to reduce the risk of recurrence. This type of surgery is typically done if the cancer has not spread to other parts of the body.
  3. Radiation Therapy: Radiation therapy follows surgery to target any remaining cancer cells in the breast or chest wall, and may also include the regional lymph nodes, further reducing the risk of local recurrence.

This aggressive, multi-faceted approach is necessary because IBC tends to spread quickly and may present without a palpable lump in the breast, making it harder to detect early. Understanding each treatment option, its role in managing IBC, potential side effects, and how to manage them can empower you to make informed decisions and feel more prepared for the journey ahead.

Systemic Treatments Overview
  • Chemotherapy: Chemotherapy is usually the first line of treatment for IBC. When given before surgery, it is called “neoadjuvant chemotherapy”. The aim of neoadjuvant chemotherapy is to reduce the size of the tumor and eliminate cancer cells throughout the body. This helps make subsequent surgery and radiation more effective.
  • Targeted Therapy: Targeted therapies are agents that specifically alter proteins and molecules on cancer cells. For example, for HER2-positive breast cancer, targeted therapies may include anti-HER2 drugs such as Trastuzumab and Pertuzumab.  Targeted therapies can be given in combination with chemotherapy agents.
  • Hormonal Therapy: For IBC that is hormone receptor-positive, hormonal therapies may be used to block hormones that fuel cancer growth. These treatments help reduce the risk of recurrence after primary treatments are completed.
  • Immunotherapy: Emerging options like immunotherapy are being explored in IBC to harness the body’s immune system to fight cancer cells. This can be particularly beneficial for patients whose cancers do not respond well to conventional treatments.

Why Systemic Treatments Are Essential: Due to IBC’s rapid progression and high likelihood of spreading to other parts of the body, systemic treatments are a cornerstone of its management. They work beyond the primary tumor site, offering a comprehensive approach to controlling the disease and improving outcomes.

Understanding your treatment plan and being aware of potential side effects allows you to better prepare for the journey ahead. We’ll guide you through each of these treatment options, including what to expect, managing side effects, and tips for coping during this challenging time.

Chemotherapy

Anthracycline and taxane-based chemotherapy are the mainstay treatments for IBC. These drugs are recommended by leading experts around the world. While the core drugs remain consistent, the specific chemotherapy schedules and dosage density may differ across treatment centres.

Anthracyclines

Anthracyclines, such as doxorubicin (Adriamycin) and epirubicin, are potent chemotherapy drugs commonly used as part of first-line treatment for IBC. They work by damaging the DNA within cancer cells, thereby preventing their ability to divide and grow.

  • Mechanism: Anthracyclines intercalate into DNA and inhibit topoisomerase II activity, disrupting DNA replication and leading to cancer cell death.
  • Application in IBC: Anthracyclines are effective in reducing tumor size and controlling the spread of cancer in IBC patients.
  • Side Effects: Common side effects include nausea, hair loss, and increased susceptibility to infections.

Taxanes

Taxanes, such as paclitaxel (Taxol) and docetaxel (Taxotere), are another class of chemotherapy drugs used to treat IBC. They work by stabilizing microtubules within cancer cells, which are essential for cell division and growth.

  • Mechanism: Taxanes interfere with microtubule function, leading to cell cycle arrest and ultimately, cell death.
  • Application in IBC: Taxanes are effective in targeting rapidly dividing cancer cells, making them a valuable part of combination therapies for IBC.

Side Effects: Side effects may include neuropathy (nerve damage), joint and muscle pain, and fluid retention.

Hormone Therapy & CDK4/6 Inhibitors

For patients with hormone receptor-positive (HR+) IBC, hormone therapy (also referred to as endocrine therapy) is used to block estrogen, which fuels cancer growth. It is often combined with CDK4/6 inhibitors to improve effectiveness.

  • Mechanism: Hormone therapy works by blocking estrogen receptors or lowering estrogen levels, preventing cancer cells from using estrogen to grow.
  • Application in IBC: Hormone therapy is used in HR+ IBC cases to slow or stop cancer growth. It is often combined with CDK4/6 inhibitors for better effectiveness.
  • Side Effects: Common side effects include hot flashes, joint pain, and bone thinning.

CDK4/6 inhibitors are used to slow down cancer cell growth by targeting proteins that regulate the cell cycle. These are typically combined with hormone therapy for HR+ IBC.

  • Mechanism: CDK4/6 inhibitors block the proteins CDK4 and CDK6, which are essential for cancer cell division. This stops cancer cells from progressing through the cell cycle.
  • Application in IBC: These inhibitors, such as abemaciclib (Verzenio), palbociclib (Ibrance), and ribociclib (Kisqali), may be used in the post-operative setting for selected IBC patients, as demonstrated by the MonarchE trial in high-risk HR+/HER2- breast cancer.
  • Side Effects: Common side effects include low blood counts, fatigue, and diarrhea.
Targeted Therapy

Targeted therapies focus on specific molecules involved in cancer growth and progression, offering more precise treatment options compared to traditional chemotherapy. There are currently limited studies on targeted therapies specifically for IBC. Given the high-risk nature of IBC, doctors often use information from studies on other high-risk breast cancers to guide treatment. For IBC, targeted therapies include:

HER2-Targeted Therapy (trastuzumab)

HER2-targeted therapies like trastuzumab (Herceptin) specifically target the HER2 protein found on the surface of some breast cancer cells. These therapies are crucial for HER2-positive IBC, improving outcomes and reducing the risk of recurrence.

  • Mechanism: Trastuzumab binds to HER2 receptors, blocking signals that promote cancer cell growth and promoting immune system recognition and destruction of cancer cells.
  • Application in IBC: Effective in HER2-positive IBC, targeted therapies like trastuzumab are integral to treatment plans, often used in combination with chemotherapy.
  • Side Effects: Potential side effects include infusion reactions and cardiac toxicity.

Pertuzumab

Pertuzumab is a monoclonal antibody that targets and binds to HER2 receptors on cancer cells. It works by inhibiting dimerization (pairing) with other HER family receptors, particularly HER3, which interferes with signaling pathways that promote cancer cell growth and survival. Pertuzumab is often used in combination with trastuzumab and chemotherapy for HER2-positive breast cancers, including IBC.

    • Mechanism: Pertuzumab inhibits HER2 dimerization with other HER family members, particularly HER3, blocking downstream signaling pathways that contribute to cancer cell proliferation.
    • Application in IBC: Used in combination with trastuzumab and chemotherapy, pertuzumab enhances the effectiveness of HER2-targeted therapies in treating HER2-positive IBC.
    • Side Effects: Common side effects include infusion reactions, diarrhea, and potential cardiac dysfunction.
    • For patients with HER2+ IBC: 
      • Who achieved a pCR: Adjuvant pertuzumab (Perjeta) and trastuzumab (Herceptin) are recommended if the cancer responds well to treatment.
      • HER2+ IBC patients who did NOT achieve a pCR: If the cancer does not respond well, then T-DM1 (trastuzumab emtansine) may be considered.
    PARP Inhibitors

    PARP inhibitors are a targeted therapy that work best for patients with BRCA1 or BRCA2 gene mutations. These drugs prevent cancer cells from repairing damaged DNA, which can lead to their death.

    • Mechanism: PARP inhibitors, such as olaparib (Lynparza) and talazoparib (Talzenna), block the PARP enzyme, which cancer cells rely on to fix DNA damage. Without this repair mechanism, the cells become unstable and die.
    • Application in IBC: PARP inhibitors are not used for all IBC patients, but they may help those with BRCA mutations, particularly in advanced or metastatic cases.
    • Side Effects: Common side effects include nausea, fatigue, and low blood cell counts, which can increase the risk of infections.
    Immunotherapy

    Immunotherapy is designed to help the immune system recognize and attack cancer cells. While it is not yet a standard treatment for IBC, it has shown promise in other aggressive breast cancers, especially triple-negative breast cancer. Clinical trials are underway to see if it could benefit IBC patients.

    • Mechanism: Immunotherapy drugs, like pembrolizumab (Keytruda) and nivolumab (Opdivo), block immune checkpoints that cancer cells use to avoid detection. By shutting down these protective barriers, immunotherapy helps the immune system identify and destroy cancer cells.
    • Application in IBC: Immunotherapy is still being studied in IBC. However, it is already approved for some triple-negative breast cancer cases, which shares similarities with triple-negative IBC. Researchers hope it may become a future treatment option.
    • Side Effects: Because immunotherapy stimulates the immune system, it can sometimes attack healthy tissues. This may cause inflammation in the lungs (pneumonitis), intestines (colitis), liver (hepatitis), or other organs.

     

    Challenges and Future Directions

    IBC remains an aggressive cancer with limited treatment options. Researchers are working to improve outcomes by exploring new approaches:

    • IBC is difficult to treat: It spreads quickly and has a high risk of recurrence.
    • Limited standard treatments: Currently, only anti-HER2 therapies (pertuzumab, trastuzumab, T-DM1) are part of standard treatment protocols.
    • Need for more research: More IBC-specific clinical trials are necessary to develop better, more effective treatments.

    As research continues, immunotherapy and PARP inhibitors could become important tools in treating certain subtypes of IBC.

    How to Prepare for Chemotherapy

    Chemotherapy is a crucial component of treating Inflammatory Breast Cancer. While it can be daunting, being well prepared can help ease the process and improve your experience. Here’s what to expect, along with some tips from those who’ve been through it:

    What to Expect:
    • Initial Consultation: Before starting chemotherapy, you’ll meet with your medical oncologist to discuss your specific treatment plan. IBC is typically treated with a combination of drugs known as a “chemotherapy regimen,” which often includes anthracyclines and taxanes. These drugs are designed to target aggressive cancer cells and shrink tumors before surgery. Your oncologist will explain the treatment schedule, potential side effects, and what to expect during your sessions, which may be more intense given the aggressive nature of IBC.
    • Port Placement: Some IBC patients, particularly those receiving long-term HER2-targeted therapy, may have a port placed (a small device implanted under the skin in the chest). This makes it easier to receive chemotherapy, targeted therapy, and blood draws without repeated needle sticks. The procedure is quick, usually done on an outpatient basis, with a short recovery time. However, not all patients require a port. Many will receive treatment through a standard IV catheter, depending on their treatment plan and medical team’s recommendation.
    • Treatment Sessions: Chemotherapy sessions for IBC can last several hours, depending on the specific drugs being administered. Treatments are often given in cycles, with rest periods in between to allow your body to recover. Bring items like a book, headphones, or a tablet to help pass the time. Given the intensity of IBC treatment, it’s important to keep yourself mentally and physically comfortable during these long sessions.
    • Side Effects: Common side effects of chemotherapy for IBC include fatigue, nausea, hair loss, changes in taste, and increased susceptibility to infections. Due to the high-dose nature of IBC chemotherapy, side effects can be more pronounced. Your medical team will provide medications and tips to help manage these symptoms and support your overall well-being during treatment.
    Patient Tips:
    • Comfort is Key: Wear comfortable clothing to your sessions, and bring a cozy blanket or pillow. Some clinics can be chilly, and comfort can make a significant difference during long treatments. 

    “Purchase chemo caps/hats in advance as hair loss typically occurs within the first couple of treatments. Make sure they are super soft – cotton or bamboo were my favourites.”

    “Wigs can be itchy and uncomfortable, so I used chemo caps with cute earrings or a hat wig when I went out.”

    • Stay Hydrated: Drinking plenty of water before and after chemotherapy can help with managing side effects like nausea and support your overall recovery. Staying hydrated is particularly important for IBC patients due to the aggressive treatment regimen. Your care team may recommend home hydration if necessary.

    “Hydrate well the whole time before and after the infusion. I also feel better when I have a drink with electrolytes during the first four days after, or any time I have the runs.”

    • Gentle Nutrition: Eat small, frequent meals that are easy on the stomach. Foods like ginger tea and crackers can help combat nausea. Because IBC treatment can be intense, focus on nutrient-rich foods that provide energy and are gentle on your digestive system.

    “Chemo is not the time to start a new diet. Everyone will tell you to focus on protein and eat what you can. You can worry about your diet after.”

    • Create a Support System: Having a friend or family members accompany you to chemo sessions can provide emotional support and help you feel more at ease. For IBC patients, having someone who understands the intensity of your treatment can be incredible comforting,

      “Accept the offers of help for meals, cleaning, driving, etc. Trust me, you will need it.”

      “Don’t be afraid to lean on your friends and family. Having someone there to hold your hand during treatment or to just listen can make a world of difference.”

      • Prepare Your Home: Before starting chemotherapy, stock up on easy-to-prepare meals, and create a cozy rest area where you can relax and recover after treatment. IBC chemotherapy can be physically demanding, so having a comfortable space ready can make a big difference.

        “Satin or silk pillowcases help if you have a tender or sensitive scalp.”

        “Prepare a basket of items that bring you comfort, like soft blankets, favorite snacks, or soothing teas, to have close by during your recovery.”

        “Having your favorite movies or shows ready to binge-watch can be a great distraction when you’re feeling up to it.”

        • Manage Side Effects: Staying on top of side effects can improve your comfort during chemo. Prepare for the potential impacts on your body and use medications or tips recommended by your care team.

        “Bring lozenges to suck on during the infusion or suck on ice chips – they seem to help keep that yucky metallic taste at bay.”

        “Have both stool softeners and Imodium at the ready – you can experience both constipation and diarrhea throughout.”

        “The Neulasta shot that they give you after chemo to increase your white blood cells can cause deep bone pain. Claritin works surprisingly well for this!”

        “Stay on top of your anti-nausea meds and don’t hesitate to call the clinic or the after-hours number for any issues with side effects. They have an arsenal of tips and tricks to combat side effects.”

        “If you’re experiencing nausea, try eating small amounts of dry toast or crackers. It can help settle your stomach.”

        “Keep your favorite snacks nearby for when you feel hungry. Sometimes, cravings can hit unexpectedly thanks to all the steroids!”

        “Ginger tea or ginger ale can be soothing for nausea; I kept some on hand during my treatment.”

        “Try to get up and move a little each day, even if it’s just a short walk. It can help with fatigue.”

        “Using a gentle moisturizer can help with dry skin, which is a common side effect of treatment.”

        “Stay ahead of mouth sores by rinsing with salt water or ask your oncologist for the ‘magic’ mouthwash.”

        “When you’re feeling too tired, don’t hesitate to take naps. Your body needs the rest to heal.”

        How to Prepare for Surgery

        Surgery is a crucial part of treating Inflammatory Breast Cancer, and being well prepared can help you face it with confidence. Here’s what you can expect, based on the widely agreed upon standard of care recommended by experts at leading institutions like Sunnybrook Health Sciences Centre and MD Anderson Cancer Center:

        What to Expect:
        • Consultation: You’ll meet with your surgeon orl oncologist to discuss the specifics of your surgery. For IBC, a modified radical mastectomy (MRM) is typically recommended. This involves removing the entire breast, including the skin, nipple, areola, and most of the axillary (underarm) lymph nodes. The aim is to remove as much of the cancer as possible to improve treatment outcomes.
        • Lymph Node Removal: During the MRM, the surgeon will also remove lymph nodes from the underarm area. This is an important step in staging the cancer and planning further treatment.
        • Skin-Sparing and Reconstruction: Immediate reconstruction is generally not advised for IBC due to the aggressive nature of the disease and the necessity of post-surgery radiation. Reconstruction is usually considered after completing all treatments, once the chest area has had time to heal.
        • Consideration of Bilateral Mastectomy: While it’s understandable to want to take every possible measure, surgeons typically prefer not to perform a prophylactic bilateral mastectomy (removal of both breasts) unless medically necessary. This approach is due to the increased risk of complications, such as infection, and the potential for treatment delays that could impact overall outcomes. Your surgical team will discuss the best approach for your individual case.
        • Drain Care: After surgery, you’ll likely have surgical drains in place to help remove excess fluid and prevent complications like fluid build-up (seromas). These drains are usually kept in place for one to two weeks.
        • Physiotherapy: Physiotherapy plays a key role in recovery, helping you regain mobility in the shoulder and arm on the side of the surgery. It also helps reduce the risk of lymphedema, which is swelling caused by the build-up of lymph fluid.
        Patient Tips:
        • Prepare for Drains: Bring button-up shirts to the hospital that can easily accommodate surgical drains. Many patients find drain belts or pouches helpful for managing drains discreetly and comfortably.

        “I found that having button-up or zip up shirts made my life so much easier, especially with the drains! You can also order mastectomy tank tops online.”

        • Post-Surgery Care: Arrange for someone to help you at home during the first week or two after surgery. This assistance can make it easier to manage daily activities, especially if you experience limited mobility.

        “I had a few friends and family members come do ‘shifts’ to help me pick up the kids, take them to their extracurriculars, assist with meals and laundry, or just keep me company, and it was a godsend!”

        • Pain Management: Discuss pain management options with your healthcare team before surgery. Managing pain effectively can make your recovery smoother.

        “Don’t hesitate to speak up about your pain. There are many options, and it’s important to find what works best for you.”

        • Arm Exercises: Start gentle arm exercises as soon as your surgeon gives the go ahead. This can help with your range of motion and prevent complications like stiffness or frozen shoulder.

        “I was surprised at how much even simple stretches helped. It felt good to move again, and it made a huge difference in my recovery.”

        • Emotional Support: Undergoing surgery for IBC can be an emotional journey. Connecting with others who’ve had similar experiences through support groups or online communities can provide valuable insights and comfort.

        “I had so much anxiety leading up to surgery, and having the support group to turn to and hearing others’ stories really helped me feel less anxious and less alone in this.”

        How to Prepare for Radiation

        Radiation therapy is a critical part of treating Inflammatory Breast Cancer, especially after surgery. Preparing for radiation can help minimize discomfort and maximize the effectiveness of your treatment. Here’s what you need to know:

        What to Expect:
        • You will first meet with your Radiation Oncologist and review your pathology after your surgery. The radiation team will make a recommendation about the radiotherapy prescription. Before starting radiation you will first undergo a CT planning session. This is the map that the radiation treatment targets. This ensures precise treatment to areas like the chest wall, underarm (axilla), and sometimes the collarbone, while protecting surrounding healthy tissue. Your radiation team will determine the radiation dose (measured in grays, Gy) and number of sessions tailored just for you based on several factors including:
          • Extent of Skin Involvement: IBC often affects the skin and underlying lymphatic vessels. Radiation is typically given at a standard dose, but in some cases, an additional boost may be used to target areas at higher risk. While some older centers may still use a traditional 50Gy dose, most centers now follow a hypofractionated approach, delivering the same total dose in fewer sessions. Your radiation team will determine the best approach based on your specific situation.
          • Use of a Bolus: For IBC patients, a bolus—a material that mimics tissue—is often applied to the skin during radiation treatments. The bolus ensures that the radiation dose is concentrated at the skin’s surface, which is crucial for IBC patients, as the disease frequently involves the skin. This technique helps to target cancer cells more effectively and reduce the risk of recurrence in the skin.
          • Radiation Boost: In addition to standard radiation therapy, an IBC patient might receive a “boost” of radiation. This boost involves delivering an extra dose of radiation directly to the area where the tumor was most active or where there is the highest risk of residual cancer cells. The boost is typically administered towards the end of the treatment course and is designed to further decrease the risk of local recurrence.
          • Surgical Margins: For IBC, ensuring clear surgical margins is crucial. If cancer cells are found at the edge of the removed tissue (positive margins), your oncologist may recommend additional radiation, such as a boost, to reduce the risk of recurrence. However, if the margins are negative (no cancer at the inked edge), a boost is generally not needed. Your radiation team will assess your specific case to determine the best approach.
          • Radiation Therapy Technique: IBC patients typically receive photon therapy, which is the standard type of radiation used for breast cancer treatment. In some cases, proton therapy may be considered, though it is less common for IBC. The way radiation is delivered can also vary. Techniques like intensity-modulated radiation therapy (IMRT) or 3D conformal radiation therapy (3D-CRT) help shape and direct the radiation to target cancer while minimizing damage to healthy tissue. Your radiation team will determine the best approach based on your specific situation.
          • Concurrent Treatments: Radiation for IBC is often coordinated with other treatments like systemic therapy. The dosage and schedule will be designed to complement these treatments without overwhelming your body.
        • Treatment Sessions: Radiation treatments for IBC are typically quick, lasting only a few minutes per session, but they occur daily over several weeks, often spanning five to six weeks. While the procedure itself is painless, it’s important to remain still during each session to ensure that the radiation precisely targets the intended areas.
        • Skin Care: The skin in the treated area may become red, dry, or irritated over time, which is a common side effect, particularly with IBC due to the higher doses often used and the application of a bolus. Your healthcare team will provide detailed guidance on how to care for your skin during treatment. Following these recommendations is essential to minimize discomfort and protect your skin.
        Patient Tips:
        • Creams and Lotions: Use gentle, unscented lotions to keep the skin moisturized. Ask your radiation team for specific product recommendations that are safe to use during radiation. Many IBC patients find relief with aloe vera gel or creams formulated specifically for radiation burns.
        • Loose Clothing: Wear soft, loose clothing to minimize irritation to the treated area. Avoid tight or rough fabrics that could rub against the sensitive skin. For IBC patients, this is particularly important as the treatment area may be extensive.
        • Hydration: Staying well-hydrated is essential during radiation therapy, especially for IBC patients who might be undergoing more intensive treatment. Drink plenty of water to support your body’s recovery and maintain healthy skin.
        • Rest and Nutrition: Radiation can cause fatigue, particularly in IBC patients due to the intensity of the treatment. Prioritize rest and ensure you’re eating a balanced diet rich in nutrients to help your body heal and maintain strength.
        • Support: Connecting with others who’ve been through radiation for IBC can provide invaluable emotional support and practical tips. Consider joining a support group where you can share experiences and gain insights specific to IBC.

        How to Prepare for Targeted Therapies:

        Targeted therapies are a key component in the treatment of Inflammatory Breast Cancer, particularly for patients whose tumors express certain biomarkers. These therapies are designed to specifically target cancer cells while sparing most normal cells, potentially reducing side effects compared to traditional chemotherapy.

        What to Expect:

        HER2-Positive IBC:

        For IBC patients whose cancer cells overexpress the HER2 protein, targeted therapies like trastuzumab (Herceptin) and pertuzumab (Perjeta) are commonly used. These drugs are monoclonal antibodies that specifically target the HER2 protein on cancer cells, helping to slow or stop the growth of the tumor.

        In Canada, trastuzumab is widely available for HER2-positive IBC patients, but access to pertuzumab may vary based on the stage of cancer and provincial guidelines. For example, pertuzumab is generally recommended for use in combination with trastuzumab and chemotherapy, particularly for HER2-positive cases with a higher risk of recurrence. However, the availability of pertuzumab and its coverage may differ depending on the province and specific patient circumstances. It is important to discuss with your oncologist about the best treatment options available and how they are covered by provincial health plans.

        Another advanced therapy for HER2-positive IBC is ado-trastuzumab emtansine (Kadcyla), an antibody-drug conjugate that delivers chemotherapy directly to HER2-positive cancer cells, minimizing damage to surrounding healthy tissue. This therapy may be used if there are residual cancer cells after initial treatments.

        Other Targeted Therapies:

        For patients with IBC who are HER2-negative but have other specific genetic mutations, targeted therapies like PARP inhibitors (e.g., olaparib) may be considered. These drugs are particularly useful for patients with BRCA1 or BRCA2 gene mutations and work by preventing cancer cells from repairing their DNA, leading to cell death.

        Clinical Trials: Due to the aggressive nature of IBC, participation in clinical trials for new targeted therapies may be recommended. Canada is home to several world-class cancer research centers, such as the Princess Margaret Cancer Centre in Toronto, which often run clinical trials for innovative IBC treatments. Your oncologist can help you explore available trials that may be appropriate for your situation.

        Patient Tips:
        • Monitoring: Regular monitoring through imaging and blood tests is essential during targeted therapy to assess how well the treatment is working and manage any side effects.
        • Side Effects: Common side effects of targeted therapies can include heart issues, diarrhea, and fatigue. It’s important to discuss any side effects with your healthcare team, as they can provide supportive care and make adjustments to your treatment plan if necessary.
        • Support: Joining an IBC-specific support group can be invaluable when undergoing targeted therapies. Other patients can share their experiences and offer advice on managing side effects and navigating the treatment process.

        How to Prepare for Hormonal Therapy:

        Hormonal therapy plays a crucial role in the treatment of Inflammatory Breast Cancer for patients whose tumors are hormone receptor-positive (HR+). This type of therapy works by blocking or lowering the levels of estrogen and progesterone in the body, which can help slow or stop the growth of hormone-sensitive cancer cells.

        What to Expect:
        • Tamoxifen: Tamoxifen is a “selective estrogen receptor modulator”, often prescribed for premenopausal women with HR+ IBC. It works by blocking estrogen receptors on cancer cells, preventing the hormone from binding and fueling the cancer’s growth. Unlike aromatase inhibitors (AIs), which lower overall estrogen levels, Tamoxifen specifically interferes with estrogen’s ability to stimulate cancer cells. It is typically taken for 5 to 10 years after initial treatment, depending on your specific situation.
        • Aromatase Inhibitors (AIs): For postmenopausal women, aromatase inhibitors such as anastrozole (Arimidex), letrozole (Femara), and exemestane (Aromasin) are commonly used. These drugs lower estrogen levels by blocking the enzyme aromatase, which is responsible for converting androgens into estrogen in the body. AIs are often prescribed for several years following surgery, chemotherapy, or radiation.
        • Ovarian Suppression: In premenopausal women, ovarian suppression may be recommended alongside tamoxifen or AIs. This can be achieved through medication such as goserelin (Zoladex) or through surgery to remove the ovaries (oophorectomy). This treatment reduces the amount of estrogen produced by the ovaries, making hormonal therapy more effective.

         

        Patient Tips:
        • Adherence: Hormonal therapy is typically a long-term treatment, sometimes termed “maintenance therapy” and adherence is crucial for reducing the risk of recurrence. It’s important to take your medication as prescribed, even if you feel well.
        • Managing Side Effects: Common side effects of hormonal therapy include hot flashes, joint pain, and bone thinning. Your healthcare team can offer strategies to manage these side effects, such as medications, lifestyle changes, or complementary therapies.
        • Bone Health: Aromatase inhibitors can increase the risk of osteoporosis, so it’s important to monitor bone density and take steps to protect your bone health. Calcium and vitamin D supplements, along with weight-bearing exercises, can be beneficial.
        • Emotional Support: Hormonal therapy can sometimes affect your mood or emotional well-being. Joining a support group or talking to a counselor who specializes in cancer care can provide much-needed support during this time.
