Inflammatory breast cancer (IBC) is an aggressive form of cancer characterized by irreversible changes in the breast, including redness, swelling, and warmth. Unlike other forms of breast cancer, IBC may not present as a tumor but as inflammation in its early stages, making it difficult to diagnose. In this regard, it is important to emphasize that the affected tissues often become dense and the skin bright pink or red, which can be misleading for both patients and specialists. IBC is characterized by a high rate of progression and a tendency to metastasize, especially to the lymph nodes.
History of the disease and interesting historical facts
Inflammatory breast cancer was first described in the medical literature in the early 19th century. In 1817, surgeon John Heigt described cases that were later classified as IBC. The disease has been the subject of study and debate among leading oncologists for many years. Interestingly, many of the initial studies focused on the relationship between inflammation in the breast and its transformation into cancer. This perception of the disease has changed throughout history, particularly with the introduction of new imaging and diagnostic techniques that have allowed for a more profound understanding of its nature.
Epidemiology
Inflammatory breast cancer is relatively rare, accounting for 1% to 5% of all breast cancer cases. According to the American Cancer Society, approximately 3,500 cases of inflammatory breast cancer are diagnosed in the United States each year. The incidence of this cancer peaks in women between the ages of 40 and 60. While the disease primarily affects women, there are rare cases in men. Epidemiological studies indicate an even distribution of cases across ethnic groups, but there is a predisposition among African American women.
Genetic predisposition to this disease
Genetic predisposition plays an important role in the development of inflammatory breast cancer. Mutations in the BRCA1 and BRCA2 genes, which are associated with hereditary breast cancer, have an exceptionally active effect on this process. According to studies, patients with these mutations have a significantly higher risk of developing breast cancer at a younger age. In addition, other genes, such as TP53 and PTEN, may also be involved in the pathogenesis of IBC. Analysis of these genes and their mutations is an important part of the modern approach to the diagnosis and treatment of this disease.
Risk factors for the development of this disease
There are several risk factors that contribute to the development of inflammatory breast cancer. These include:
- Heredity - the presence of cases of breast cancer in the family.
- Age - the risk increases with age, especially after 40 years.
- Lifestyle – smoking, drinking alcohol and poor diet can increase the risk.
- Hormonal factors - long-term hormonal therapy, late menopause.
- Recurrent inflammatory processes and injuries of the mammary gland.
These factors may act in combination to increase the likelihood of developing the disease. They highlight the need for early diagnosis and regular medical examinations for women at risk.
Diagnosis of this disease
Diagnosis of inflammatory breast cancer begins with a physical examination and history. The main symptoms of IBC include:
- Swelling and redness of the skin of the mammary gland.
- Observed change in the shape and size of the breast.
- A feeling of warmth in the affected area.
- Itching and burning in the mammary gland.
To confirm the diagnosis, doctors use various methods:
- Laboratory tests - general and biochemical blood tests, determination of tumor markers.
- Radiological examination - mammography and ultrasound.
- A biopsy is a cytological or histological examination of tissue.
- Immunohistochemistry - to determine the hormonal receptivity of the tumor.
Differential diagnosis includes exclusion of other diseases, such as infectious processes and benign neoplasms.
Treatment
Treatment of inflammatory breast cancer requires a multidisciplinary approach, including surgical, pharmacological and radiation therapy. Surgery is an important step, and most often, mastectomy (removal of the breast) is recommended, followed by chemotherapy and/or radiotherapy. Pharmacological therapy includes:
- Chemotherapy is the administration of cytostatics such as doxorubicin and paclitaxel.
- Hormonal therapy - drugs that block the action of estrogens.
- Targeted therapy is the use of anti-HER2 drugs such as trastuzumab.
Each treatment method is selected individually depending on the stage of the disease and the general condition of the patient. If necessary, doctors can use combined approaches to increase the effectiveness of the treatment process.
List of medications used to treat this disease
Various groups of drugs are used to treat inflammatory breast cancer:
- Cytostatics: Doxorubicin, Paclitaxel.
- Antihormonal drugs: Tamoxifen, Anastrozole.
- Targeted therapy: Trastuzumab, Pertuzumab.
- Immunotherapy: Pembrolizumab, Atezolizumab.
These drugs are selected based on the individual characteristics of the tumor and the patient's health status.
Disease monitoring
Monitoring of patients with inflammatory breast cancer includes regular examinations, clinical examinations and radiological examinations. The stages of monitoring are:
- Initial examinations 3-6 months after completion of treatment.
- Annual examination after 5-year control.
- Screening for recurrence and metastases using ultrasound and mammography.
The prognosis for patients with IBC depends on the stage at diagnosis, but overall survival is poor, especially in the later stages. Complications may include recurrence of the disease and metastasis.
Age-related features of the disease
Inflammatory breast cancer can present differently depending on the patient’s age. In younger women, the disease can be more aggressive, often with symptoms developing quickly. In older women, the cancer is often diagnosed at a later stage, which also worsens the prognosis. In addition, after age 60, there is a greater risk of comorbidities, which complicates the choice of treatment regimen.
Questions and Answers
- What are the main symptoms of inflammatory breast cancer? The main symptoms include swelling, redness of the skin, significant changes in the shape and size of the mammary gland, itching and burning in the chest area.
- What factors increase the risk of developing IBC? Risk factors include heredity, age, poor nutrition, smoking and hormonal imbalances.
- How is IBC diagnosed? Diagnosis is made using physical examination, laboratory tests, radiological methods and biopsy.
- What are the main treatment methods for this disease? Treatment includes surgery, chemotherapy, radiation therapy and hormonal therapy.
- What is the prognosis after treatment for IBC? The prognosis depends on the stage of the disease at diagnosis, as well as the general health of the patient. Survival is generally low in the later stages.
Advice from Dr. Oleg Korzhikov
Dr. Oleg Korzhikov advises patients to be attentive to any changes in their mammary glands. “Even slight redness or swelling may require immediate medical attention. Regular examinations and studying the medical history will help in early detection of the disease.” He adds that it is important to lead a healthy lifestyle, eat right and avoid bad habits to reduce the risk of developing the disease. It is also recommended to keep in touch with medical specialists for timely diagnosis and treatment.
