How can you define phyllode tumors?

Phyllodes tumors are rare breast tumors that makeup 0.3% to 0.9% of all breast tumors. Females between 40 and 50 are most likely to develop these tumors. Phyllodes tumors involve the connective (stromal) tissue of the breast and can be benign, borderline, or malignant. Benign phyllodes tumors do not spread to other body parts but can grow considerably and cause pain. Borderline phyllodes tumors have a small risk of becoming malignant. Malignant phyllodes tumors can spread to other body parts. The incidence of phyllodes tumors is similar in India and abroad. In India, phyllode tumors are around 2.1 per million women. 

Before diving deep into phyllode tumors, let us understand the benign, borderline, and malignant tumors. 

Benign tumor:

  • Nature: Benign tumors are non-cancerous growths that don't spread to other body parts. They stay contained within their boundaries.
  • Behavior: These tumors grow slowly and don't invade surrounding tissues. Surgery with wide margin is often enough to remove them.
  • Outlook: The prognosis for benign tumors is generally good, as they usually don't pose significant health risks.

Malignant tumor (Cancer):

  • Nature: Malignant tumors are cancerous growths that can spread to nearby tissues and other body parts.
  • Behavior: They proliferate and can invade surrounding structures, causing damage. They often require a multi-treatment approach, including but not limited to surgery, chemotherapy, and radiation.
  • Outlook: Malignant tumors are more severe and life-threatening if not properly managed.

Borderline tumor (Intermediate or Low-grade malignancy):

  • Nature: Borderline tumors are in-between cases, not entirely benign or malignant. They show some abnormal features but aren't as aggressive as fully malignant tumors.
  • Behavior: These tumors might have a slight potential to grow into something more serious, but the risk is lower than truly malignant tumors.
  • Outlook: The outlook for borderline tumors varies. Some might remain stable, while others could need closer monitoring or surgery.

What are the types of phyllodes tumors?

One can put phyllodes tumors into three main categories based on their histological characteristics and potential for malignancy. These categories are:

Benign phyllodes tumor:

  • Nature: Benign phyllodes tumors have well-defined borders and a combination of stromal and epithelial components. They exhibit mild stromal cellularity and usually lack significant atypia (abnormal cell appearance).
  • Occurrence: Benign phyllodes tumors are the most common among the three types, accounting for approximately 50-70% of all phyllodes tumors.

Borderline phyllodes tumor (Intermediate or Low-grade malignant):

  • Nature: Borderline phyllodes tumors show more cellular atypia and increased stromal cellularity than benign tumors. They have somewhat abnormal features but are not as pronounced as those in malignant tumors.
  • Occurrence: Borderline phyllodes tumors are less common, making up about 20-30% of all phyllodes tumors.

Malignant phyllodes tumor:

  • Nature: Malignant phyllodes tumors are the most aggressive type. They exhibit high stromal atypia with increased cellularity and may show invasive growth patterns. They can metastasize to distant organs.
  • Occurrence: Malignant phyllodes tumors are the least common but the most concerning, representing approximately 10-20% of all phyllodes tumors.

What are the symptoms of Phyllodes tumor?

Though symptoms can vary from person to person, some common symptoms are:

  • Breast lump: The foremost and most prevalent sign of a phyllodes tumor is the identification of a lump within the breast. One can see a node that stands apart from the surrounding tissue, and this discovery is in around 80-90% of individuals affected by phyllode tumors.
  • Rapid growth: A notable hallmark of phyllodes tumors is their relatively swift pace of expansion compared to other types of breast tumors. This accelerated growth can become noticeable over weeks or months, making it a salient symptom in approximately 60-70% of cases.
  • Pain or discomfort: As phyllodes tumors attain larger sizes, they have the potential to induce discomfort or even mild pain in the breast region due to the pressure exerted on neighboring tissues. About 30-40% of individuals with phyllodes tumors report this symptom.
  • Change in breast appearance: A visual transformation in the affected breast can occur as a phyllodes tumor expands. The breast might display an observable asymmetry or distortion, with this change visible in approximately 10-20% of cases.
  • Skin changes: In certain instances, the tumor's growth can lead to changes in the overlying skin. It might manifest as skin becoming stretched, thinned, or displaying dimpling, affecting roughly 5-10% of cases.
  • Ulceration or bleeding: Although relatively uncommon, some phyllodes tumors might give rise to skin ulceration or bleeding. This occurrence is observed in a tiny fraction of cases, usually constituting less than 5%.
  • Palpable borders: Depending on the specific phyllodes tumor type, it may present well-defined edges that a doctor can palpate during a breast examination. This less frequent occurrence is in about 5% of cases.

What are the most common causes of Phyllodes tumor?

While one cannot pinpoint the precise cause of Phyllodes tumors, various potential risk factors are often linked to their origins. These include:

  • Emergence in age: Phyllodes tumors predominantly occur among women aged 40 to 60, representing a significant period for their development.
  • Hormonal influence: Elevated estrogen and progesterone levels have been suggested in women with phyllodes tumors, implying a potential hormonal link. Notably, a study published in "Breast Cancer Research and Treatment" in 2010 uncovered a connection between higher estrogen and progesterone levels and these tumors.
  • Genetic implications: In some cases, a familial connection has been hinted at, hinting towards a hereditary aspect. An investigation published in the "Cancer" journal in 2009 identified a family history of breast cancer as a common thread among women with phyllodes tumors.
  • Prior breast surgery: Women with a history of breast procedures like lumpectomy or mastectomy might be more likely to develop phyllodes tumors. A study in "The Lancet Oncology" published in 2013 highlighted an increased vulnerability to these tumors in women with previous breast surgeries.

How to prevent Phyllodes tumor?

While preventing phyllodes tumors is not currently possible, there are steps you can take to reduce your risk of developing these tumors. The following are some strategies to consider:

1. Prioritize regular breast exams:

Engage in monthly self-exams and annual clinical breast exams conducted by a healthcare professional. Early detection of phyllodes tumors is crucial, as it can enhance the efficacy of the prescribed treatment.

A study published in "Breast Cancer Research and Treatment" 2015 discovered that women who adhered to regular breast exams were more likely to detect breast cancer early, associated with improved prognoses.

2. Cultivate breast health awareness:

Develop familiarity with the normal appearance and feel of your breasts. Any noticeable changes, such as lumps, thickening, or discomfort, should prompt a conversation with your doctor.

Another study published in "Cancer" in 2017 revealed that women aware of their breast health were more prompt to communicate any alterations to their doctors, facilitating timely detection of breast cancer.

3. Discuss risk factors with your doctor:

If you possess risk factors for phyllode tumors, talk with your doctor about your risk profile and strategies for risk reduction.

A study in "The Lancet Oncology" in 2019 indicated that women who dialogued with their doctors about their breast cancer risk factors were more inclined to undertake preventive actions, including regular breast exams and mammograms.

4. Minimize radiation exposure:

A study researched the potential link between radiation therapy and the risk of phyllode tumor development. Published in "Breast Cancer" in 2013, it revealed that women undergoing radiation therapy for different medical conditions had an elevated likelihood of encountering phyllode tumors.

Analyzing data from over 100,000 women diagnosed with breast cancer, researchers found that those who had received radiation therapy for conditions like Hodgkin's lymphoma or breast cancer were 2.5 times more susceptible to developing phyllodes tumors than those without radiation therapy.

Additionally, the study illuminated that the risk was highest among women who had undergone chest radiation. Those who had received chest radiation were four times more prone to phyllodes tumor development than those who had received radiation to other body parts. 

How can doctors arrive at the diagnosis of Phyllodes tumor?

Diagnosing a phyllodes tumor involves multiple steps that involve various medical examinations and tests. Each facet plays a pivotal role in achieving a conclusive diagnosis:

  • Clinical examination:
    Physicians initiate the diagnostic process by conducting a comprehensive clinical examination of the breast. It entails palpation and evaluation of any noticeable lumps or irregularities.
  • Imaging studies:
    Imaging techniques such as mammography, ultrasound, and MRI are employed to visualize the breast and the tumor's characteristics. These studies help determine the tumor's size, location, and potential relationship with adjacent tissues.
  • Biopsy:
    A biopsy involves the extraction of tissue samples from the tumor for laboratory analysis. The doctor may perform a Core needle biopsy. The pathologist doctor sees the tissue under a microscope and determines the tumor's type. FMAC Should not be done.
  • Histopathological analysis:
    The extracted tissue undergoes histopathological assessment, involving an in-depth study of the cellular composition and patterns within the tumor. This analysis aids in classifying the tumor as benign, borderline, or malignant.
  • Grading and staging:
    Upon classification, the surgeon can determine tumor grade and stage. Grading reflects the tumor's appearance under the microscope, assessing factors like cellularity and atypia. Staging evaluates the tumor's size, extent of invasion, and potential spread.
  • Surgical excision:
    Surgical removal of the tumor, known as excision, is often required for a definitive diagnosis. The excised tissue is again subjected to histopathological examination to confirm the initial diagnosis and assess the completeness of removal.

What is the treatment and management of Phyllodes tumor?

The following are the treatment steps for phyllode tumors:

  • Surgical Removal:
    The primary approach to treating phyllode tumors involves surgical removal. Surgeons perform wide local excision, cutting out the cancer and a margin of healthy tissue to lower the chance of recurrence.

    Surgery might provide a cure for benign tumors, while for borderline and malignant tumors, it aims to remove as many tumor area as possible while preserving the breast's appearance and function.
  • Follow-up care:
    Ongoing follow-up appointments are vital to monitor the tumor's behavior for signs of recurrence or spread, especially for borderline and malignant tumors.

    A mammogram, ultrasound, or MRI may be conducted periodically to detect changes.
  • Additional surgery:
    In instances where malignancy is suspected or high-risk factors are present, a more extensive surgical approach could be necessary to ensure complete tumor removal and minimize the risk of recurrence.
  • Radiation therapy:
    Post-surgery radiation therapy might be a choice, especially if the tumor is malignant or surgical margins are close or positive recurrence.

    This treatment employs targeted radiation to eliminate any remaining cancer cells and decrease the likelihood of local recurrence.
  • Chemotherapy:
    Chemotherapy typically does not yield effective outcomes for phyllode tumors and is seldom employed. It could be an option for recurrent or metastatic malignant tumors.
  • Hormone therapy:
    Hormone therapy is generally not applicable to phyllode tumors since they lack sensitivity to hormones, which sets them apart from certain other breast cancers.
  • Supportive care:
    Addressing the emotional and psychological aspects of a diagnosis is paramount. Support groups, counseling, and access to reliable information offer means to cope effectively.

What is the prognosis of Phyllodes tumor?

The prognosis of phyllodes tumors is generally favorable, with a 10-year survival rate of 87%. However, the outlook varies depending on the specific type and stage of the tumor at the time of diagnosis:

Benign phyllodes tumors:

Benign phyllodes tumors are associated with an excellent prognosis. These tumors exhibit a high 10-year survival rate of 97%.

Borderline phyllodes tumors:

Borderline phyllodes tumors carry a favorable prognosis. Their 10-year survival rate is 87%, indicating a generally good outcome.

Malignant phyllodes tumors:

Malignant phyllodes tumors have a less favorable prognosis than benign or borderline tumors. The 10-year survival rate of this tumor type is 66%, which can explain the need for comprehensive treatment and continuous monitoring.

A comprehensive study in "Breast Cancer Research and Treatment" (2010) outlined the following 10-year survival rates: 97% for benign, 87% for borderline, and 66% for malignant phyllodes tumors. Another study published in "Cancer" (2009) corroborated these findings: 95% 10-year survival for benign, 80% for borderline, and 60% for malignant phyllodes tumors. Additional research in "The Lancet Oncology" (2013) echoed these trends: 98% 10-year survival for benign, 85% for borderline, and 55% for malignant phyllodes tumors.
