Mesothelioma surgical treatment is a critical component in helping patients fight malignant mesothelioma — a rare and aggressive cancer primarily caused by asbestos exposure.
Surgical treatments aim to remove as much of the cancerous tissue as possible, alleviate symptoms, and improve the patient’s quality of life. The primary goals of surgery in mesothelioma treatment include extending survival, reducing tumor burden, and enhancing the effectiveness of other treatments like chemotherapy and radiation for mesothelioma patients.
Conventional treatments for mesothelioma often involve a combination of surgery, chemotherapy, and radiation therapy, tailored to the patient’s specific condition and overall health.
Types of Mesothelioma Surgery
There are several types of mesothelioma surgery designed to treat different stages and forms of the disease. The three primary surgical treatments are Extrapleural Pneumonectomy (EPP), Pleurectomy/Decortication (P/D), and Cytoreductive Surgery with HIPEC.
Thoracic surgery is a critical component in the treatment of mesothelioma, particularly pleural mesothelioma. The main types of thoracic surgeries used to treat mesothelioma include:
Extrapleural Pneumonectomy (EPP)
Extrapleural Pneumonectomy (EPP) is an extensive surgical procedure primarily used for malignant pleural mesothelioma. It involves the removal of the mesothelioma tumor in the affected lung, part of the diaphragm, the pleura (lining of the lung), and often part of the pericardium (lining of the heart).
The benefits of EPP include the potential for the complete removal of visible tumors, which can significantly extend survival in selected patients. However, the risks are substantial, including complications such as infection, bleeding, and respiratory issues. Ideal candidates for EPP are typically younger patients with good overall health and early-stage mesothelioma confined to one side of the chest.
Pleurectomy/Decortication (P/D)
Pleurectomy/Decortication (P/D) is a lung-sparing surgery that involves the removal of the pleura and any visible tumors without removing the lung itself. This procedure is less invasive than EPP and is often preferred for patients who may not tolerate the removal of an entire lung.
The benefits of P/D include reduced surgical risks and preservation of lung function, which can lead to a better quality of life post-surgery. However, it may not be as effective in completely removing all cancerous tissue. Ideal candidates for P/D are those with early to moderate-stage mesothelioma who are not suitable for EPP due to health or age-related factors.
Cytoreductive Surgery with HIPEC
Cytoreductive Surgery with HIPEC (Hyperthermic Intraperitoneal Chemotherapy) is primarily used for peritoneal mesothelioma, which affects the lining of the abdomen. This procedure involves the surgical removal of visible tumors followed by the direct application of heated chemotherapy into the abdominal cavity.
The heat enhances the effectiveness of the chemotherapy, targeting any remaining mesothelioma cancer cells. The benefits of this approach include improved survival rates and reduced recurrence of the disease.
However, the risks include infection, bowel obstruction, and complications related to the chemotherapy. Ideal candidates for this surgery are patients with peritoneal mesothelioma cancer who are in good overall health and can tolerate the intensive procedure.
Pre-Surgical Evaluation and Preparation
A thorough pre-surgical evaluation is crucial for mesothelioma patients to ensure they are suitable candidates for surgery by a mesothelioma doctor to plan the best possible treatment approach. This preoperative evaluation involves a series of diagnostic tests and assessments to evaluate the patient’s overall health and the extent of the disease.
The physical examination is the first step of this cancer treatment, where the doctor assesses the patient’s general health, lung function, and any symptoms related to pleural mesothelioma. This is followed by imaging tests such as CT scans, MRI, and PET scans to determine the size, location, and spread of the tumors. These imaging tests provide detailed information that helps in planning the surgical approach.
Pulmonary function tests are essential to evaluate the patient’s lung capacity and function, especially if the surgery involves the removal of lung tissue. These tests measure how well the lungs are working and help predict how the patient will tolerate the surgery. Cardiopulmonary exercise testing may also be conducted to assess the patient’s heart and lung function during physical activity.
Blood tests are performed to check for any underlying conditions that could affect surgery, such as anemia, clotting disorders, or kidney and liver function. Echocardiograms and electrocardiograms (EKG) are used to evaluate heart function and ensure the patient can withstand the stress of surgery.
A detailed anesthesia evaluation is also conducted to plan for the administration of anesthesia during surgery. This includes reviewing the patient’s medical history, any previous reactions to anesthesia, and current medications.
The Surgical Procedure
During pleural mesothelioma surgery, the patient is placed under general anesthesia to ensure they are unconscious and pain-free throughout the procedure. The specific steps of the surgery depend on the type of procedure being performed.
For Extrapleural Pneumonectomy (EPP), the surgeon makes an incision in the chest to access the affected lung and surrounding tissues. The lung, part of the diaphragm, pleura, and pericardium are carefully removed. The diaphragm and pericardium are then reconstructed using synthetic materials. This invasive surgery typically lasts several hours due to its complexity.
In Pleurectomy/Decortication (P/D), the surgeon makes an incision in the chest and removes the pleura and any visible tumors while sparing the lung. This procedure is less extensive than EPP and may involve minimally invasive surgery techniques, such as video-assisted thoracoscopic surgery (VATS), which uses small incisions and a camera to guide the surgery.
Cytoreductive Surgery with HIPEC involves making an incision in the abdomen to remove visible tumors. After the tumors are removed, a heated chemotherapy solution is circulated in the abdominal cavity for about 90 minutes to kill any remaining cancer cells. This combination of surgery and chemotherapy aims to reduce the risk of recurrence.
Recovery and Post-Surgical Care
The recovery process after mesothelioma surgery varies depending on the type of surgery and the patient’s overall health. Post-surgical care involves close monitoring in the hospital, typically in an intensive care unit (ICU) for the first few days.
Pain management is a critical aspect of post-operative care, with medications administered to control pain and discomfort. Wound care is also essential to prevent infection and promote healing. Patients are encouraged to engage in breathing exercises and physical therapy to improve lung function and overall mobility.
The recovery time can range from several weeks to a few months, depending on the extent of the surgery and the patient’s response to treatment. A customized care plan is developed for each patient, including follow-up appointments, additional treatments, and rehabilitation to support their recovery and improve their quality of life.
Risks and Complications
Mesothelioma surgery carries several risks and complications, both short-term and long-term. Short-term complications may include infection, bleeding, and reactions to general anesthesia. Deep vein thrombosis (DVT) and urinary tract infections are also potential risks following surgery.
Long-term complications can include respiratory issues, such as reduced lung function and chronic pain. Patients may also experience complications related to the removal of organs or tissues, such as hernias or bowel obstructions.
To manage and mitigate risks, patients are closely monitored during and after surgery. Preventive measures, such as blood thinners to reduce the risk of DVT and antibiotics to prevent infections, are commonly used. Regular follow-up appointments are essential to detect and address any complications early.
Outcomes and Survival Rates
The effectiveness of surgery in treating mesothelioma varies based on several factors, including the stage of the disease, the patient’s overall health, and the type of surgery performed. Survival rates post-surgery can provide insight into the success of surgical treatments.
Studies have shown that patients who undergo Extrapleural Pneumonectomy (EPP) have a median survival rate of approximately 12-18 months, while those who undergo Pleurectomy/Decortication (P/D) may have a median survival rate of 20-30 months. Cytoreductive Surgery with HIPEC for peritoneal mesothelioma has shown promising results, with some patients achieving long-term survival.
Success factors influencing surgical outcomes include the completeness of tumor removal, the patient’s response to additional treatments, and overall health and fitness levels.
Combining Surgery with Other Treatments
Combining surgery with other mesothelioma treatments, such as chemotherapy, radiation, and immunotherapy, offers a comprehensive approach to managing the disease. This multimodal treatment strategy aims to maximize the effectiveness of each treatment modality.
Chemotherapy is often used before or after surgery to shrink tumors and kill remaining cancer cells. Radiation therapy can target specific areas to reduce the risk of recurrence. Immunotherapy helps boost the body’s immune system to fight cancer more effectively.
The benefits of combining treatments include improved survival rates, reduced tumor burden, and enhanced quality of life for patients.
