Adrenal cancer

Καρκίνος Επινεφριδίου

Adrenal cancer, also known as adrenocortical carcinoma, is a rare form of cancer that develops in the adrenal glands. The adrenal glands are a pair of small, triangular-shaped organs located on top of each kidney. These glands have two main parts: the outer layer (the adrenal cortex) and the inner layer (the adrenal medulla). Adrenal cancer typically originates in the adrenal cortex, which is responsible for producing various hormones, including cortisol, aldosterone, and sex hormones.
Adrenal cancer arises when abnormal cells in the adrenal cortex undergo uncontrolled growth and form tumors. These tumors can be benign (non-cancerous) or malignant (cancerous). Malignant adrenal tumors are what is referred to as adrenal cancer.
Adrenal cancer is considered a rare disease, with a low incidence rate. It can affect people of all ages, but it is most often diagnosed in adults, typically between the ages of 40 and 50.




Adrenal cancer, also known as adrenocortical carcinoma, is a rare form of cancer, and its risk factors are not as well-defined as those of more common cancers. However, there are some factors that may increase the risk of developing adrenal cancer, including:

  1. Genetic Predisposition: Certain genetic syndromes are associated with an increased risk of adrenal cancer. These include:

    • Li-Fraumeni Syndrome: This rare genetic disorder is characterized by a mutation in the TP53 gene, which significantly raises the risk of various cancers, including adrenal cancer.

    • Beckwith-Wiedemann Syndrome: Individuals with this syndrome may have an increased risk of developing adrenal cancer. It is associated with alterations in certain genes, such as the IGF2 gene.

  2. Age: Adrenal cancer can occur at any age, but it is most commonly diagnosed in adults, typically between the ages of 40 and 50.

  3. Gender: Adrenal cancer appears to affect men and women equally, with no significant gender-based differences in risk.

  4. Hereditary Conditions: Some hereditary conditions, like congenital adrenal hyperplasia and multiple endocrine neoplasia type 1 (MEN1), may slightly elevate the risk of adrenal cancer.

  5. Chemical Exposures: While limited evidence exists, some studies have suggested that exposure to certain chemicals or toxins might be associated with a slightly increased risk of adrenal cancer. However, the role of environmental exposures remains unclear.

  6. Hormonal Factors: There is some evidence that certain hormonal factors, such as hormonal replacement therapy (HRT) in postmenopausal women, may be linked to an increased risk of adrenal cancer. However, this connection is not well-established.

It's important to note that adrenal cancer is rare, and most cases occur sporadically without a clear identifiable cause or the presence of known risk factors. The majority of people who develop adrenal cancer do not have a family history of the disease.
If you have concerns about your risk of adrenal cancer, particularly if you have a family history of related genetic syndromes, it is advisable to seek genetic counseling and undergo regular medical monitoring to detect the disease at an early, potentially more treatable stage.

Causes of Adrenal Cancer


Adrenal cancer, also known as adrenocortical carcinoma, may produce a variety of symptoms. However, it's important to note that not everyone with adrenal cancer experiences noticeable symptoms, especially in the early stages. When symptoms do occur, they can vary depending on the hormones produced by the tumor. Common symptoms of adrenal cancer can include:

  1. Hypertension (High Blood Pressure): Adrenal tumors, especially those in the adrenal cortex, may produce excess hormones like aldosterone, which can lead to high blood pressure. Hypertension caused by adrenal cancer is often difficult to control with medications.

  2. Weight Gain: Some adrenal tumors can produce excessive cortisol, a hormone that regulates metabolism. An excess of cortisol can lead to unexplained weight gain, particularly in the face, neck, and abdomen.

  3. Muscle Weakness: High cortisol levels may also cause muscle weakness, making daily activities more challenging.

  4. Excess Hair Growth (Hirsutism): In some cases, adrenal tumors may lead to excessive hair growth in women. This condition is called hirsutism.

  5. Irregular Menstrual Periods (In Women): Adrenal tumors that produce hormones like androgens can cause irregular menstrual periods and other menstrual disturbances in women.

  6. Changes in Sex Drive: Hormone imbalances related to adrenal cancer can affect sexual desire and function.

  7. Abdominal Pain: As the tumor grows, it can lead to abdominal or flank pain on the side where the affected adrenal gland is located.

  8. Feeling Full Early During Meals: An enlarged adrenal tumor may press against the stomach, leading to early satiety, or feeling full shortly after starting a meal.

  9. Fatigue: Individuals with adrenal cancer may experience persistent fatigue, which can be related to the effects of hormonal imbalances and the tumor's growth.

  10. Sweating Excessively: Some people with adrenal cancer may experience excessive sweating, particularly at night.

It's important to emphasize that the symptoms of adrenal cancer can vary widely and may be mistaken for other medical conditions. Additionally, some adrenal tumors do not produce noticeable symptoms until they reach an advanced stage. As a result, adrenal cancer is often diagnosed during routine medical examinations or when investigating other unrelated health issues.
If you experience persistent, unexplained symptoms that raise concerns about adrenal cancer, or if you have risk factors for the disease, it is advisable to consult with a healthcare provider for a thorough evaluation and appropriate diagnostic tests. Early detection and diagnosis are essential for improving outcomes in adrenal cancer.

The diagnosis of adrenal cancer, also known as adrenocortical carcinoma, involves a series of medical evaluations, tests, and procedures to confirm the presence of cancer, determine its stage, and guide treatment decisions. Here is an overview of the diagnostic process for adrenal cancer:

  1. Medical History and Physical Examination:

    • The initial step is often a comprehensive medical history, during which the healthcare provider discusses any symptoms, risk factors, and relevant health information.

    • A thorough physical examination is conducted to assess the abdomen, the location of the adrenal glands, and the presence of any masses or abnormalities.

  2. Imaging Studies:

    • Imaging tests are used to visualize the adrenal glands and any potential tumors. Common imaging studies may include:

      • Computed Tomography (CT) Scan: This provides detailed images of the adrenal glands and surrounding structures.

      • Magnetic Resonance Imaging (MRI): An MRI may be used to further assess the adrenal glands.

      • Ultrasound: Ultrasound imaging may be used to visualize the adrenal glands and detect any masses or tumors.

  3. Hormone and Tumor Marker Testing:

    • Blood and urine tests may be performed to measure the levels of specific hormones and tumor markers associated with adrenal cancer. Common tumor markers include cortisol, aldosterone, dehydroepiandrosterone sulfate (DHEA-S), and others.

  4. Biopsy:

    • A definitive diagnosis of adrenal cancer often involves a biopsy. During this procedure, a small sample of the affected tissue is removed for examination. Biopsies can be performed using various methods, such as fine-needle aspiration or core needle biopsy.

    • It's important to note that adrenal cancer can sometimes be challenging to diagnose definitively with a biopsy due to the risk of tumor cells spreading during the procedure. Therefore, imaging and clinical findings often play a significant role in the diagnosis.

  5. Staging:

    • If adrenal cancer is confirmed, it is staged to determine the extent of the disease. Staging helps assess whether the cancer is localized to the adrenal gland or has spread to other parts of the body.

  6. Genetic Testing: In some cases, genetic testing may be recommended to identify any underlying genetic mutations that could contribute to the development of adrenal cancer.

The results of these diagnostic tests and procedures guide the healthcare team in developing a personalized treatment plan tailored to the specific characteristics of the cancer and the patient's overall health. Treatment options for adrenal cancer typically involve surgical removal of the tumor, sometimes with surrounding tissue and lymph nodes. Additional treatments, such as chemotherapy, radiation therapy, or targeted therapy, may be recommended based on the stage and extent of the cancer.
Adrenal cancer is relatively rare, and the complexity of its diagnosis requires the expertise of healthcare providers experienced in its evaluation and treatment. Early detection and prompt diagnosis are essential for improving outcomes in individuals with adrenal cancer.


Symptoms of Adrenal Cancer

Diagnosis of Adrenal Cancer

The treatment of adrenal cancer, also known as adrenocortical carcinoma, depends on several factors, including the stage of the cancer, the patient's overall health, and the extent of tumor spread. Treatment typically involves a combination of approaches and may include the following:

  1. Surgery: Surgery is the primary treatment for adrenal cancer and is often the first step in managing the disease. The surgical procedure, called adrenalectomy, involves the removal of the affected adrenal gland, and sometimes nearby lymph nodes or other tissues if they are involved. The goal is to achieve complete removal of the tumor, also known as achieving "negative margins."

  2. Lymph Node Dissection: In cases where there is lymph node involvement, your surgeon may perform a lymph node dissection to remove affected lymph nodes in the region.

  3. Chemotherapy: Chemotherapy involves the use of powerful drugs to destroy cancer cells or slow their growth. Chemotherapy is typically considered for patients with advanced or metastatic adrenal cancer. Common chemotherapy drugs used for adrenal cancer include mitotane, doxorubicin, etoposide, and cisplatin.

  4. Radiation Therapy: Radiation therapy uses high-energy X-rays or other forms of radiation to target and destroy cancer cells. It is sometimes used after surgery or in cases where the tumor cannot be completely removed. Radiation therapy may also be used for palliative care to relieve symptoms and slow the progression of the disease.

  5. Targeted Therapy: Targeted therapy drugs specifically target cancer cells or the pathways that support their growth. In some cases, targeted therapies, such as mitotane, may be used to treat adrenal cancer.

  6. Immunotherapy: Immunotherapy drugs work by stimulating the immune system to recognize and attack cancer cells. They may be used in clinical trials or for certain cases of advanced adrenal cancer.

  7. Clinical Trials: Participation in clinical trials may be an option for some patients with adrenal cancer. These trials test new treatments or combinations of treatments that have not yet become standard practice.

  8. Hormone Replacement Therapy: After removal of one adrenal gland, hormone replacement therapy may be necessary to provide the hormones that the body can no longer produce. This therapy can help maintain hormonal balance in the body.

The specific treatment plan for adrenal cancer is determined by a multidisciplinary healthcare team, which may include surgeons, medical oncologists, radiation oncologists, and other specialists. Treatment decisions are based on factors such as the stage of the cancer, the presence of metastases, the type of tumor, and the patient's overall health.
Adrenal cancer is a rare and complex disease, and it is important for individuals with this condition to receive care from healthcare providers with expertise in the diagnosis and treatment of the disease. Early detection and prompt, appropriate treatment are crucial for improving outcomes in adrenal cancer.
