Pleurectomy Decortication Surgery
Research Guide
What is Pleurectomy Decortication Surgery?
Pleurectomy decortication (P/D) is a lung-sparing surgical procedure that removes the pleural lining and visible tumor in patients with malignant pleural mesothelioma while preserving pulmonary function.
P/D contrasts with extrapleural pneumonectomy (EPP), which sacrifices the entire lung. Flores et al. (2008) analyzed 663 patients, showing P/D associated with improved survival over EPP (17.4 vs. 14.4 months median). Over 600 papers cite P/D techniques in mesothelioma multimodality therapy.
Why It Matters
P/D enables multimodality treatment with chemotherapy and radiation while maintaining quality of life through preserved lung function (Flores et al., 2008; 605 citations). Sugarbaker et al. (1999) identified resection margins and nodal status as survival predictors in 183 trimodality patients, guiding patient selection (979 citations). Rusch et al. (2001) demonstrated feasibility of P/D with adjuvant hemithoracic radiation in phase II trials, influencing ESMO guidelines (Baas et al., 2015; 491 citations).
Key Research Challenges
Patient Selection Criteria
Identifying candidates suitable for P/D remains challenging due to heterogeneous mesothelioma staging. Rusch and Venkatraman (1999) highlighted prognostic factors like cell type in surgically managed patients (251 citations). Sugarbaker et al. (1999) stressed extrapleural nodal status for long-term survival in trimodality therapy.
Perioperative Complication Management
Post-P/D complications like effusions and respiratory failure require early detection protocols. Sugarbaker et al. (2004) detailed management after 328 EPPs, applicable to P/D with similar risks (388 citations). Antony et al. (2001) addressed malignant pleural effusions in 15% of cancer deaths (525 citations).
Survival Outcome Prediction
Predicting long-term survival post-P/D versus EPP lacks standardized models. Flores et al. (2008) reported superior P/D survival in 663 patients but noted cell type influences. De Perrot et al. (2009) evaluated trimodality with EPP, underscoring need for P/D-specific predictors (286 citations).

Reading Guide
Foundational Papers
Start with Sugarbaker et al. (1999; 979 citations) for trimodality survival predictors in 183 patients, then Flores et al. (2008; 605 citations) for P/D vs EPP in 663 cases, establishing core techniques and outcomes.
Recent Advances
Study Baas et al. (2015; ESMO guidelines; 413 citations) for current P/D recommendations, and Bibby et al. (2016; 300 citations) for diagnostic updates in asbestos-related mesothelioma.
Core Methods
Core techniques include macroscopic complete resection (Sugarbaker 1999), adjuvant hemithoracic radiation (Rusch 2001), and effusion management (Antony 2001). Multimodality integrates cisplatin-based chemotherapy (de Perrot 2009).

What methods compare P/D to EPP?
Flores et al. (2008) retrospectively compared P/D (n=496) vs EPP (n=167) showing superior survival. Sugarbaker et al. (1999) used trimodality with margins/nodes analysis.
What are key papers on P/D?
Sugarbaker et al. (1999; 979 citations) on trimodality survival factors; Flores et al. (2008; 605 citations) on P/D vs EPP; Rusch et al. (2001; 491 citations) on resection with radiation.
What open problems exist in P/D research?
Standardized patient selection models and long-term randomized trials vs EPP. Gaps in predicting complications persist despite Sugarbaker et al. (2004) protocols.
