In this comprehensive guide, we will learn about Adrenocortical Carcinoma (ACC), a rare and aggressive form of cancer originating in the cortex of the adrenal glands. The adrenal glands above each kidney are crucial for producing hormones that control metabolism, immune system function, blood pressure, & other vital bodily functions. ACC poses unique challenges due to its abnormality & the complexity of its symptoms, diagnosis, and treatment.
This article provides a comprehensive overview of Adrenocortical Carcinoma, covering various aspects such as symptoms, diagnostic procedures, potential causes, and treatment options. Whether you are a patient or medical professional, our goal is to offer valuable insights & up-to-date information to help you understand and navigate this challenging condition.
Understanding the symptoms of ACC is crucial for early detection and effective treatment. This section will delve into the common and less common symptoms associated with ACC, which can vary greatly depending on the tumour’s hormone activity. Some tumours may produce excess hormones, leading to conditions such as Cushing’s syndrome or virilisation, while others may remain non-functional and present symptoms related to the tumour’s mass effect.
While the exact cause of ACC remains largely unknown, several risk factors and genetic conditions have been identified that may increase the likelihood of developing this cancer. This section will explore potential genetic mutations, inherited syndromes like Li-Fraumeni and Beckwith-Wiedemann, and other contributing factors that researchers believe might play a role in the onset of ACC.
Adrenocortical Carcinoma is a complex and rare cancer that needs a multidisciplinary approach for proper management. This blog aims to shed light on every aspect of ACC, from symptoms and diagnosis to treatment and support. By raising awareness and providing accurate information, we hope to empower readers with the knowledge needed to face ACC with confidence and hope.

Adrenocortical Carcinoma Symptoms
Adrenocortical carcinoma (ACC) is a rare kind of cancer that begins in the outer layer (cortex) of the adrenal glands. These glands are on top of each kidney and produce hormones regulating various body functions. The symptoms of ACC can vary widely because the tumour can produce excess hormones or grow large enough to press on nearby organs. Here’s a detailed yet simple explanation of the symptoms:
Hormone-Related Symptoms
ACC can cause the adrenal glands to produce too many hormones, leading to various symptoms based on which hormone is overproduced:
1. Excess Cortisol (Cushing’s Syndrome):
– Weight Gain: Especially around the face, neck, & trunk, while limbs stay thin.
– Facial Changes: A round, moon-like face.
– Skin Changes: Thinning skin, easy bruising, and purple stretch marks on the abdomen.
– Muscle Weakness: Particularly in the arms & legs.
– High Blood Pressure & Blood Sugar Levels Can lead to diabetes.
– Mood Swings: Irritability, anxiety, or depression.
2. Excess Aldosterone:
– High Blood Pressure: Difficult to control with standard medications.
– Muscle Cramps and Weakness: Low potassium levels (hypokalemia).
– Frequent Urination and Thirst: Because of the imbalance in body salts.
3. Excess Androgens (Male Sex Hormones) or Estrogens (Female Sex Hormones):
– In Women: Excess hair growth (hirsutism), deepening of the voice, menstrual irregularities, and increased muscle mass.
– In Men: Breast enlargement (gynecomastia) and reduced libido or impotence.
Symptoms Due to Tumor Growth
If the tumour grows large, it may press on nearby organs, causing symptoms such as:
– Abdominal Pain or Discomfort: A feeling of fullness or pain in the abdomen or back.
– Feeling of a Mass: Sometimes, a mass can be felt in the abdomen.
General Symptoms
These symptoms are more nonspecific and can occur with many types of cancer:
changes
– Unusual Weight Loss: Without changes in diet or exercise.
– Fatigue: Feeling tired or weak, even after getting enough rest.
-Loss of Appetite: This refers to not feeling hungry or not wanting to eat.
Diagnosis and When to See a Doctor
If you experience a combination of these symptoms, it’s important to see a doctor. Early diagnosis and treatment can improve outcomes. Doctors may use blood tests, imaging studies (like CT scans or MRIs), and sometimes a biopsy to confirm the presence of an adrenocortical carcinoma.
In summary, ACC symptoms can be very diverse, often linked to excess hormone production or the physical presence of the tumour. Noticing these symptoms early and seeking medical advice is crucial for effective treatment.
Adrenocortical Carcinoma Diagnosis
The diagnosis of ACC often begins with the observation of symptoms or during imaging tests for other conditions. Symptoms can differ widely depending on whether the tumour is functioning (hormone-producing) or non-functioning. Functioning tumours may lead to various symptoms due to excess hormone production, such as high blood pressure, weight gain, or changes in hair growth patterns.
Imaging Tests
Imaging tests are crucial in the diagnosis of ACC. These may include:
Computed Tomography (CT) Scan: This procedure provides detailed cross-sectional images of the body and can detect tumours in the adrenal gland.
– Magnetic Resonance Imaging (MRI): Offers detailed images of soft tissues and is useful in determining the extent of the tumour.
Positron Emission Tomography (PET) Scan: This test, often combined with a CT scan (PET-CT), can help identify cancerous cells throughout the body.
Laboratory Tests
Blood & urine tests are conducted to measure hormone levels, which can be indicative of ACC:
– Blood Tests: Check for abnormal levels of adrenal hormones.
– Urinalysis: Measures hormones and their byproducts in the urine over 24 hours.
Biopsy
Sometimes, a biopsy may be performed, in which a tumour sample is removed and examined under a microscope. However, this is less common due to the risk of spreading cancer cells during the medical procedure.
Adrenocortical Carcinoma Causes
Adrenocortical carcinoma (ACC) is an uncommon & aggressive cancer originating in the adrenal cortex. While the precise causes of ACC remain unclear, various factors and genetic conditions are associated with a higher likelihood of developing this kind of cancer.
Genetic Factors
1. Hereditary Syndromes: Certain inherited genetic syndromes increase the risk of ACC:
– Li-Fraumeni Syndrome: Induced by mutations in the TP53 gene, this syndrome significantly increases the risk of various cancers, including ACC.
– Beckwith-Wiedemann Syndrome: This overgrowth disorder caused by genetic changes on chromosome 11 can increase the likelihood of ACC.
– MEN1, or Multiple Endocrine Neoplasia type 1: It’s a hereditary condition that impacts endocrine glands and increases the likelihood of developing tumours, such as adrenal tumours.
– Familial Adenomatous Polyposis (FAP): This condition, due to mutations in the APC gene, primarily causes colon cancer but also increases the risk for other cancers, including ACC.
2. Genetic Mutations: Somatic mutations in specific genes can drive the development of ACC:
– TP53: Mutations in the TP53 gene, a tumour suppressor gene, are common in ACC and contribute to uncontrolled cell growth.
CTNNB1: Mutations in the CTNNB1 gene, which encodes beta-catenin, are implicated in the Wnt signalling pathway and affect cell proliferation and differentiation.
Environmental and Lifestyle Factors
While the role of environmental and lifestyle factors in ACC is less clear compared to genetic factors, potential influences might include:
– Exposure to Carcinogens: Long-term exposure to certain chemicals or environmental toxins could potentially increase the risk of developing adrenal gland cancers.
– Hormonal Factors: Imbalances or excessive production of certain hormones might contribute to the development of ACC, although the evidence is not definitive.
Other Considerations
Age and Gender: ACC can occur at any age but is most common in children under 5 and adults between 40 and 50. It affects females more often than males.
– Sporadic Cases: Many cases of ACC are sporadic, meaning they occur without a clear inherited genetic cause or known environmental trigger.
Adrenocortical carcinoma’s causes are complex and multifactorial, involving a combination of genetic predispositions and potential environmental influences. Understanding the underlying genetic mutations and hereditary conditions can help in identifying at-risk individuals & developing targeted therapies for this aggressive cancer.
Adrenocortical Carcinoma Prognosis
The prognosis for ACC is influenced by many factors, and understanding these can help manage the disease more effectively.
The stage at diagnosis is a critical determinant of prognosis. Localised tumours confined to the adrenal gland have a better prognosis than those that have spread (metastasised). The five-year survival rate for localised ACC is approximately 60-65%, while regional spread to nearby structures reduces the rate to about 35-40%. Distant metastases, such as to the lungs or liver, further lower the survival rate to around 10-20%.
The size and functionality of the tumour also play a role in the prognosis. Functioning tumours, which secrete hormones, may present with symptoms earlier, potentially leading to earlier diagnosis. However, depending on the hormones produced, these symptoms can be varied and sometimes nonspecific, such as abdominal pain, weight gain, or high blood pressure.
Surgical resection of the tumour is the mainstay of treatment & offers the best chance for a cure, especially if the cancer can be obliterated and has not spread. The surgeon’s expertise and the resection’s completeness are significant prognostic factors.
Another important prognostic indicator is the pathological grade of the tumour, which refers to how unusual the cancer cells look under a microscope. Low-grade tumours, which look more like normal cells, tend to grow & spread more slowly than high-grade tumours, which look very abnormal.
Patients with non-functioning tumors, which do not produce hormones, may have a delayed diagnosis since they often lack symptoms until the tumour grows large enough to cause discomfort or affect nearby organs.
Adrenocortical Carcinoma Staging
The staging of ACC generally adheres to two primary systems: the AJCC TNM staging system and the ENSAT staging system from the European Network for the Study of Adrenal Tumors. Both systems are based on three key factors: the size & extent of the tumour (T), whether cancer has spread to surrounding lymph nodes (N), and whether there is metastasis to distant parts of the body (M).
The TNM classification is as follows:
– T (Tumor): Denotes the size of the primary tumour and if it has grown into nearby areas.
– N (Nodes): Denotes any spread of cancer to lymph nodes near the adrenal gland.
– M (Metastasis): Refers to whether the tumour has spread to distant sites, like different body organs or lymph nodes that are not near the adrenal gland.
After determining the T, N, and M categories, usually post-surgery, these are merged in a process called stage grouping to assign an overall stage from I to IV. The stages signify the following:
– Stage I: The tumour is 5 centimeters or smaller and confined to the adrenal gland.
– Stage II: The tumour is bigger than 5 centimeters but still confined to the adrenal gland.
– Stage III: Cancer has extended to neighbouring lymph nodes or adjacent tissues but has not reached distant body organs.
– Stage IV: The cancer has metastasised to remote body parts.
The stage of ACC is one of the most important factors in deciding the treatment approach and determining the prognosis. Lower stages generally indicate a better prognosis and may be managed with surgery alone, while higher stages might require additional treatments like chemotherapy or radiation therapy.
Adrenocortical Carcinoma Treatment
The primary treatment for Adrenocortical Carcinoma is surgery, which involves removing the tumour and possibly the entire affected adrenal gland. This is often followed by chemotherapy to destroy any remaining cancer cells. Radiation therapy or targeted therapy might also be advised in certain medical situations.
The cost of treatment in India varies depending on the hospital and the specific treatments required. On average, the cost ranges from INR 4,00,000 to INR 10,00,000. This includes pre-operative tests, hospital stays, surgeon fees, anaesthesia, and post-operative care. Compared to other countries, patients can save significantly by opting for treatment in India’s top hospitals.
Patients need to discuss all these factors with their healthcare providers to get a comprehensive understanding of the potential costs involved.
Conclusion
In conclusion, Adrenocortical Carcinoma (ACC) is a rare but aggressive cancer originating in the adrenal cortex. Understanding its symptoms, which range from hormonal imbalances to abdominal pain, is crucial for early detection. Accurate diagnosis typically involves imaging studies, blood tests, and biopsy procedures. While the exact causes of ACC remain unclear, genetic factors and certain hereditary conditions may increase risk. Advancements in medical research continue to improve diagnostic techniques and treatment options, offering hope for better patient outcomes. Awareness and timely medical intervention are key in managing this complex disease.
ACC treatment often involves surgery, chemotherapy, and sometimes radiation therapy, all of which can be pricey.
