EPP vs P/D: Choosing the Right Mesothelioma Surgery

Quick Comparison Overview

What is EPP (Extrapleural Pneumonectomy)?

EPP is the more radical of the two surgeries. During this procedure, the surgeon removes:

• The entire affected lung
• The pleura (lining of the chest wall and lung)
• Portions of the diaphragm
• The pericardium (lining around the heart)
• All visible tumor tissue

The diaphragm and pericardium are then reconstructed using surgical mesh. The goal is to remove as much cancerous tissue as possible, potentially achieving macroscopic complete resection (removing all visible tumors).

Pros of EPP

• More complete tumor removal possible
• May be more effective for advanced disease
• Allows for higher-dose radiation to hemithorax (one side of chest)
• May prevent local recurrence in the pleural space

Cons of EPP

• Permanent loss of one lung
• Higher surgical risk and complication rate
• Longer recovery time
• Reduced quality of life due to single lung
• Cannot be performed if patient has poor lung function

What is P/D (Pleurectomy/Decortication)?

P/D is a lung-sparing surgery. The surgeon removes:

• The pleura (lining) from the chest wall and lung surface
• All visible tumor tissue
• May include portions of diaphragm or pericardium if involved

The lung itself is left in place and allowed to re-expand. This procedure is technically challenging as the surgeon must carefully peel the cancerous tissue away from the lung surface without damaging the underlying lung tissue.

Pros of P/D

• Lung-sparing preserves pulmonary function
• Lower surgical mortality risk
• Faster recovery
• Better quality of life post-surgery
• More patients eligible for the procedure
• Can be repeated if cancer recurs

Cons of P/D

• May leave microscopic disease behind
• Higher risk of local recurrence
• Cannot use high-dose radiation (would damage remaining lung)
• Technically difficult procedure requiring experienced surgeon

Which Surgery is Right for You?

Candidates for EPP

EPP may be appropriate for patients who:

• Have epithelioid cell type (not sarcomatoid)
• Have good overall health and performance status
• Have adequate lung function in the unaffected lung
• Have no spread to lymph nodes (N0) or limited spread (N1)
• Have tumors that cannot be completely removed without lung removal
• Are willing to accept higher risk for potentially greater benefit

Before proceeding with EPP, surgeons typically order pulmonary function tests and cardiac imaging to ensure the patient can tolerate the removal of one lung.

Candidates for P/D

P/D may be appropriate for patients who:

• Have any cell type (including sarcomatoid)
• Have borderline lung function
• Are older or have other health conditions
• Have early-stage disease (tumors limited to pleural surface)
• Want to preserve lung function
• Prefer lower surgical risk

The EPP vs P/D Debate

The mesothelioma medical community has debated which surgery is superior for decades:

Historical Context

Dr. David Sugarbaker at Brigham and Women's Hospital popularized EPP in the 1990s, reporting extended survival with the procedure. However, critics noted the high morbidity and mortality rates.

Modern Trends

In recent years, many surgeons have shifted toward P/D as the preferred approach because:

• Studies show similar or better survival with lower morbidity
• Patients report better quality of life
• More patients are eligible
• Advances in chemotherapy and immunotherapy may make radical surgery less necessary

Current Consensus

Most experts now agree that:

• Both surgeries can be effective in appropriate patients
• Surgeon experience matters more than procedure choice
• Patient selection is critical
• Neither surgery is appropriate for all patients

Survival Statistics

Important: Direct comparison is difficult because patients selected for EPP often have more advanced disease. When matched for disease stage, outcomes appear similar.

Questions to Ask Your Surgeon

1. How many of these procedures have you performed? (Look for high-volume surgeons)
2. What are your complication rates?
3. Which procedure do you recommend for me and why?
4. What happens if you start one procedure and need to convert to the other?
5. What is the multimodal treatment plan? (Surgery + chemo + radiation?)
6. What is my expected quality of life after each procedure?
7. Can I get a second opinion from another mesothelioma specialist?

Second Opinions Matter

Because the EPP vs P/D decision is complex and opinions vary among surgeons, seeking a second opinion from another mesothelioma specialist is highly recommended. Some surgeons specialize in EPP while others prefer P/D—getting multiple perspectives can help you make the best decision for your situation. Recovery expectations differ significantly between the two procedures, which is why understanding post-surgery care and recovery protocols is essential for informed decision-making.

Frequently Asked Questions

Can I have EPP after P/D if cancer returns?

Generally no—once P/D is performed, EPP is typically not possible. However, P/D can sometimes be repeated if cancer recurs locally.

Which procedure is more painful?

Both are major surgeries with significant post-operative pain. EPP may involve more pain initially due to the larger surgical field, but pain management protocols are effective for both procedures.

Can I exercise after EPP with only one lung?

Yes, many patients return to exercise after EPP. The remaining lung typically expands to compensate. However, you may have reduced exercise capacity compared to having two lungs.

Does insurance cover both procedures?

Both EPP and P/D are generally covered by insurance when performed as part of cancer treatment at an in-network facility. However, you should verify coverage with your insurer.
