Inflammatory Breast Cancer

---

Summary

Inflammatory Breast Cancer (IBC) is a rare and aggressive form of breast cancer that differs significantly from more common types of breast cancer. It is characterized by its rapid progression and unique presentation, often resembling an infection or inflammation rather than a typical breast cancer.

Symptoms

IBC typically presents with symptoms that can be mistaken for a breast infection or other inflammatory conditions. Key symptoms include:

• Redness: The breast may appear red, resembling an infection.
• Swelling: The breast can become swollen and tender.
• Warmth: The affected area often feels warmer than the surrounding skin.
• Pitted Skin Texture: Known as "peau d'orange," the skin may take on a dimpled appearance similar to an orange peel.
• Rapid Change: Symptoms can develop quickly, often within weeks.
• Nipple Changes: Inversion or flattening of the nipple may occur.
• Enlargement: The breast may increase in size rapidly.

Treatments

Treatment for IBC typically involves a multi-modal approach, combining several types of therapies to address the aggressive nature of the disease. The standard treatment regimen includes:

1. Chemotherapy: Administered before surgery (neoadjuvant chemotherapy) to shrink the tumor and address any potential spread of cancer cells.

   • Common Drugs: Doxorubicin, Cyclophosphamide, Paclitaxel.
   • Side Effects: Hair loss, nausea, fatigue, increased risk of infection.

2. Surgery: Post-chemotherapy, a mastectomy is usually performed to remove the affected breast tissue.

   • Side Effects: Pain, swelling, risk of infection, changes in body image.

3. Radiation Therapy: Used after surgery to eliminate any remaining cancer cells in the breast and surrounding areas.

   • Side Effects: Skin irritation, fatigue, swelling.

4. Targeted Therapy: For tumors that express certain proteins (e.g., HER2-positive), targeted drugs like Trastuzumab (Herceptin) are used.

   • Side Effects: Heart problems, fever, chills.

5. Hormone Therapy: If the cancer is hormone receptor-positive, treatments like Tamoxifen or Aromatase inhibitors may be prescribed.

   • Side Effects: Hot flashes, risk of blood clots, bone thinning.

These treatments have been standard since the early 2000s, with ongoing research continually improving protocols and outcomes.

Experimental Treatments

Research into novel treatments for IBC is ongoing, with several experimental therapies being explored:

• Immunotherapy: Aims to harness the body's immune system to fight cancer cells. Drugs like Pembrolizumab are being tested in clinical trials.

  • Side Effects: Autoimmune reactions, fatigue, skin rashes.

• PARP Inhibitors: These drugs target cancer cells with specific genetic mutations, like BRCA1/2, to prevent DNA repair and induce cell death.

  • Side Effects: Nausea, fatigue, anemia.

• Clinical Trials: New drugs and combinations are constantly being evaluated in clinical trials. Participants may gain access to cutting-edge therapies not yet widely available.

Modernity of Treatments

The treatments for IBC have evolved significantly over the past two decades. Chemotherapy, surgery, and radiation remain the cornerstone of treatment, with targeted therapies becoming more refined since the early 2000s. Immunotherapy and PARP inhibitors represent the most modern approaches, with active research and trials as of the 2020s, offering hope for improved outcomes.
