Invasive Breast Carcinoma Treatment: Latest Approaches and Options
By Prashant Baghel
Invasive breast carcinoma (IBC) is a prevalent and aggressive subtype of breast cancer, originating from the milk ducts or lobules and subsequently disseminating to adjacent tissues. Finding the disease early is very important for improving survival rates and making treatment more effective.
Over the last few decades, the treatment for IBC has changed a lot. Now, patients have a lot of choices that are tailored to the specific type of tumor they have. Surgery, chemotherapy, radiation, hormone therapy, and targeted therapies are all very important for treating IBC. This article looks at the newest treatments for invasive breast carcinoma and how they help patients get better.
What is breast cancer that has spread?
Invasive breast carcinoma is cancer that has spread from the milk ducts or lobules to the breast tissue around them. There are two main types: Invasive Ductal Carcinoma (IDC) and Invasive Lobular Carcinoma (ILC).
IDC is the most common type of breast cancer, accounting for about 70–80% of all cases. ILC is less common but just as aggressive. The stage and type of the cancer have a big impact on the treatment plan and prognosis, even though early-stage IBC can often be treated successfully.
Surgical Intervention for Invasive Breast Carcinoma
Surgery is the most important part of treating invasive breast cancer. The goal of surgery is to get rid of the tumor and make sure the cancer doesn't spread to other parts of the body. Two main kinds of surgery are used to treat IBC:
Lumpectomy: A lumpectomy takes out just the tumor and a small amount of tissue around it, leaving the rest of the breast alone. It is usually suggested for smaller tumors that haven't spread to the lymph nodes yet. This kind of surgery is thought to be breast-conserving because it lets patients keep most of their breast tissue.
Mastectomy: If the tumor is big or the cancer has spread a lot, a mastectomy may be needed. This means taking out the whole breast. In some cases, a double mastectomy (removal of both breasts) may be suggested, especially for patients who have a family history of breast cancer or other risk factors.
After surgery, breast reconstruction can often be done to make the breast look normal again. Many patients recover faster and with less trauma thanks to improvements in surgical techniques, such as minimally invasive surgery.
Chemotherapy: A Way to Treat Metastatic Cancer All Over the Body
Chemotherapy is a common way to treat invasive breast cancer, especially when it has spread to lymph nodes or other parts of the body. Chemotherapy uses strong drugs that attack and kill cells that are dividing quickly all over the body, not just in the breast. You can get chemotherapy through an IV or in pill form.
- The decision to use chemotherapy depends on things like the size and stage of the tumor.
- Lymph node involvement
- The existence of hormone receptors (specifically estrogen or progesterone receptors)
- HER2 status (a protein that helps cancer cells grow)
Chemotherapy is often given to people with HER2-positive breast cancer along with Herceptin (trastuzumab), a targeted therapy that only works on HER2 proteins. Chemotherapy can cause side effects like tiredness, nausea, hair loss, and a higher risk of infection, but it is still a very effective treatment for many women with invasive breast cancer.
Radiation Therapy: Focusing on Remaining Cancer Cells
Radiation therapy is often used after surgery to kill any cancer cells that might still be there, especially if the tumor was big or spread to the lymph nodes. Radiation therapy kills cancer cells with high-energy beams, like X-rays.
There are two main kinds of radiation therapy:
- External Beam Radiation: This kind of radiation therapy uses a machine to send radiation beams to the breast tissue where the tumor was removed. This is the most common type of radiation therapy used after surgery.
- Brachytherapy: Brachytherapy is a type of radiation therapy that puts radioactive materials right inside or very close to the tumor area. It is not used as often, but it can work in some situations.
Radiation therapy can make you tired, irritated skin, and swollen, but these side effects usually go away on their own and can be treated with medical care.
Hormone Therapy: Treating Hormone-Receptor Positive Cancer
Hormone therapy is used to treat breast cancers that have hormone receptors. This means that the cancer cells are fed by estrogen or progesterone. Hormone receptor-positive or negative invasive breast carcinoma affects treatment choices.
The main kinds of hormone therapy are:
Tamoxifen: This medicine stops estrogen from making cancer cells grow by blocking estrogen receptors on those cells.
Aromatase Inhibitors: Aromatase inhibitors are drugs that lower the amount of estrogen the body makes. They are usually given to women who have already gone through menopause.
Hormone therapy is usually given for five to ten years after surgery to lower the chance of cancer coming back. It is an important part of treatment for people with hormone-receptor-positive invasive breast cancer, and studies have shown that it can help them live longer.
Targeted Therapy: A Specific Treatment for Invasive Breast Cancer
Targeted therapy is a newer and more precise way to treat cancer that focuses on certain molecules that help the disease grow. Targeted therapies can be more effective and have fewer side effects than standard treatments like chemotherapy because they focus on the genetic mutations or proteins that help cancer cells stay alive.
Some well-known targeted therapies for invasive breast carcinoma are:
Trastuzumab (Herceptin): This drug is for HER2-positive breast cancer, which is a type of breast cancer that makes too much of the HER2 protein, which makes cancer grow.
CDK4/6 inhibitors: it's like Ibrance (palbociclib), slows the growth of hormone receptor-positive, HER2-negative breast cancers by stopping the cyclin-dependent kinases that control cell division.
Depending on the type of cancer, targeted therapies are often used with chemotherapy or hormone therapy. They are especially helpful for people who have certain genetic profiles or receptor statuses.
Immunotherapy: A New Way to Treat Invasive Breast Cancer
Immunotherapy is a modern treatment method that boosts the immune system to help the body fight cancer. Immunotherapy is still being studied, but it looks like it could work for some types of invasive breast cancer that don't respond well to chemotherapy or hormone therapy, like triple-negative breast cancer (TNBC).
Immunotherapy works by stopping the proteins that stop immune cells from finding and attacking cancer cells. Checkpoint inhibitors are one example. They can help the immune system find and kill cancer cells more effectively.
Many cancers, like breast cancer, are still in the clinical trial phase for immunotherapy. But it has a lot of promise for helping some patients get better, and big advances are expected in the next few years.
Invasive Breast Carcinoma Survival Rates
The survival rate for invasive breast carcinoma differs based on the cancer stage, treatment response, and specific patient characteristics. In general, the sooner cancer is found, the better the chances of getting rid of it. The five-year survival rate for localized invasive breast carcinoma (cancer that hasn't spread) is about 99%.
The rate goes down to about 85–90% for regional cancer, which has spread to nearby lymph nodes. People with advanced-stage or metastatic cancer have a lower chance of living, but ongoing research and new treatments are making things better for these patients.
Conclusion: Advances in Treatment for Invasive Breast Carcinoma
Many women around the world are still very worried about invasive breast cancer. But many patients' chances of recovery have gotten a lot better thanks to early detection and the development of new treatment options like surgery, chemotherapy, radiation therapy, hormone therapy, and targeted therapies. New treatments like immunotherapy and targeted therapies give patients with aggressive forms of breast cancer hope, and personalized treatment plans are helping more people survive.
