Surgical and Medical Therapies for Adrenocortical Carcinoma

January 13, 2024by Dr. Shehrezad Czar0

Adrenocortical carcinoma (ACC) is a rare and aggressive cancer originating in the cortex (outer layer) of the adrenal gland. Given its complexity and rarity, the treatment of ACC poses significant challenges, necessitating a comprehensive approach that includes both surgical and medical therapies. This article aims to explore current treatment methodologies and delve into potential future directions in the management of ACC.

Current Approaches to Adrenocortical Carcinoma

Surgical Intervention

  1. Primary Treatment Modality: Surgery remains the cornerstone for treating ACC. The primary goal is the complete resection of the tumor, which is the only potentially curative treatment. This procedure often involves a radical adrenalectomy, where the entire adrenal gland is removed along with surrounding fat and nearby lymph nodes.
  2. Minimally Invasive Techniques: Laparoscopic surgery is increasingly preferred for its minimally invasive nature, leading to faster recovery and less postoperative pain. However, its suitability depends on the tumor’s size and stage.
  3. Challenges in Surgery: Given ACC’s propensity for local invasion and metastasis, achieving complete resection can be challenging. The involvement of adjacent organs might necessitate more extensive surgical procedures.

Medical Therapies

  1. Mitotane Therapy: Mitotane, an adrenolytic drug, is a cornerstone in the medical treatment of ACC. It selectively destroys adrenocortical cells, and is used both as an adjuvant therapy following surgery and for inoperable cases. However, its side effects, like gastrointestinal and neurological disturbances, must be carefully managed.
  2. Chemotherapy: For advanced or metastatic ACC, chemotherapy regimens, typically including etoposide, doxorubicin, and cisplatin, along with mitotane, are used. These regimens are chosen based on their efficacy in reducing tumor size and controlling symptoms.
  3. Targeted Therapy and Immunotherapy: Research is ongoing in the use of targeted therapies (like IGF-1 inhibitors) and immunotherapy, but these are not yet standard treatments for ACC. Clinical trials are exploring their efficacy and safety profiles.

Future Directions in ACC Management

Advancements in Surgical Techniques

  1. Robotic Surgery: There is growing interest in the use of robotic-assisted surgery for ACC. This could offer greater precision, reduced blood loss, and quicker recovery times.
  2. Intraoperative Imaging: Advanced imaging techniques, like intraoperative ultrasound, can aid surgeons in achieving more precise tumor resection, especially in complex cases.

Personalized Medical Therapy

  1. Genetic and Molecular Profiling: Understanding the genetic and molecular characteristics of ACC can lead to more personalized treatment approaches. Targeted therapies could be developed to attack specific mutations or pathways involved in tumor growth.
  2. Immunotherapy: The future of ACC treatment may include immunotherapy, which harnesses the body’s immune system to fight cancer. Identifying biomarkers that predict response to immunotherapy could be a significant step forward.

Combination Therapies

  1. Synergistic Approaches: Combining surgery with preoperative or postoperative medical therapies could improve outcomes. For instance, preoperative chemotherapy might reduce tumor size, making surgery more feasible.
  2. Radiation Therapy: Though not a mainstay of treatment currently, radiation therapy might have a role in combination with surgery and chemotherapy, especially in managing local recurrences.

Enhancing Early Detection

  1. Biomarkers for Early Diagnosis: Developing biomarkers for early detection of ACC is crucial. Early-stage cancers are more amenable to successful treatment, highlighting the need for research in this area.
  2. Screening Protocols: For high-risk individuals, such as those with genetic predispositions, establishing effective screening protocols could facilitate early detection and treatment.

Ongoing Research and Clinical Trials

  1. Clinical Trials: Numerous clinical trials are currently underway, investigating new drugs, drug combinations, and treatment strategies for ACC. These trials are crucial for discovering more effective and less toxic treatments.
  2. Molecular Research: Understanding the molecular pathways involved in the development and progression of ACC is a major focus of current research. This could lead to the development of novel targeted therapies.
  3. Resistance to Therapy: Research into why some ACC tumors are resistant to certain therapies could lead to more effective treatment regimens and the avoidance of ineffective treatments.

Supportive Care and Quality of Life

  1. Psychosocial Support: The psychological impact of an ACC diagnosis and its treatment is significant. Comprehensive care models that include psychological support and counseling are essential.
  2. Managing Side Effects: Effective management of the side effects of treatments like mitotane and chemotherapy is crucial for maintaining the quality of life of patients. This includes nutritional support, pain management, and addressing hormonal imbalances.

Global Collaboration and Awareness

  1. International Collaboration: Due to the rarity of ACC, international collaboration in research and sharing of clinical data is vital. This can lead to more robust studies and faster advancements in treatment.
  2. Raising Awareness: Increasing awareness of ACC among healthcare professionals and the general public can lead to earlier diagnosis and treatment, which is key to improving survival rates.

Ethical and Economic Considerations

  1. Access to Treatment: There are disparities in access to the best care for ACC, often related to geographic and economic factors. Addressing these disparities is crucial for equitable healthcare.
  2. Cost of Treatment: The high cost of treatments, particularly new and experimental therapies, poses a significant challenge. Efforts to make these treatments more affordable and accessible are needed.

The Role of Technology

  1. Artificial Intelligence and Machine Learning: These technologies could play a role in diagnosing ACC, predicting treatment outcomes, and personalizing treatment plans based on individual patient data.
  2. Telemedicine: Telemedicine can be particularly beneficial for ongoing management and follow-up of ACC patients, especially those in remote areas or with mobility issues.


The management of adrenocortical carcinoma is rapidly evolving. While current surgical and medical therapies offer hope, there is a continuous need for innovation and research. The future holds promise with advancements in personalized medicine, molecular targeted therapies, and immunotherapy. Equally important are the efforts to improve early detection, patient support, and access to care. Collaboration between oncologists, surgeons, researchers, and patients is key to overcoming the challenges posed by this rare cancer and improving outcomes for those affected by it.

In summary, the journey in combating ACC is multifaceted, combining current medical knowledge with cutting-edge research. As we move forward, it’s essential to maintain a focus on both the scientific advancements and the holistic care of patients, ensuring that treatment approaches not only extend life but also enhance its quality.
