7031 Background: Induction chemotherapy followed by extrapleural pneumonectomy (EPP) for resectable malignant pleural mesothelioma (MPM) is controversial. To select optimal candidates for EPP, we evaluates the usefulness of metabolic response on fluorodeoxyglucose-positron emission tomography (FDG-PET) compared with radiologic response on high-resolution computed tomography (HRCT) after induction chemotherapy to predict prognosis for patients with resectable MPM who underwent EPP in the setting of multicenter study. Methods: We performed HRCT and FDG-PET before and after induction platinum-based chemotherapy on 50 patients with clinical T1-3 N0-2 M0 MPM who underwent EPP ± postoperative hemithoracic radiation. A decrease of more than 30% in tumor maximum standardized uptake value (SUVmax) was defined as a metabolic responder. Radiologic response using modified RECIST or metabolic response and surgical results were analyzed. Results: In all cohort patients, median overall survival (OS) from diagnosis was 20.5 month (95% confidence interval [CI], 15.0-26.0 month). Fourteen patients were classified as metabolic responders (28%) and 36 as non-responders (72%). Metabolic responders significantly correlated to OS with median OS for metabolic responders of not reached (3-year OS of 60.0%) versus 18.7 month (95% CI, 13.3-24.2 month, 3-year OS of 26.5%) for non-responders (P = .025). No correlation was observed between OS and radiologic response with median OS for radiologic responders of 25.7 month (n = 20, 95% CI, 14.5-37.0 month, 3-year OS of 35.8%) versus 17.7 month (n = 30, 95% CI, 12.8-22.6 month, 3-year OS of 35.1%) for non-responder (p = .216). Based on the multivariate Cox analyses, decreased SUVmax (%) (p = .010) was a significantly independent factor for OS as well as epithelioid subtype (p = .044). Conclusions: Metabolic response on FDG-PET has higher predictive value of prognosis than radiologic response on HRCT after induction chemotherapy for patients with resectable MPM. Patients with metabolic responder and/or epithelioid subtype can be good candidates for EPP after induction chemotherapy.

Purpose Response evaluation with conventional criteria based on computed tomography (CT) is particularly challenging in malignant pleural mesothelioma (MPM) due to its diffuse pattern of growth. There is growing evidence that therapy-induced changes in tumor [18F]fluorodeoxyglucose (FDG) uptake as measured by positron emission tomography (PET) may predict response and patient outcome early in the course of treatment. Patients and Methods Patients with histologically proven MPM, not candidates to curative surgery, scheduled to undergo palliative chemotherapy with a pemetrexed-based regimen were eligible for this study. Patients were evaluated by FDG-PET and CT at baseline and after two cycles of therapy. A decrease of 25% or more in tumor FDG uptake as measured by standardized uptake value was defined as a metabolic response (MR). Best overall response from CT scans was determined according to previously published criteria. Results Twenty-two patients were included in the study, and 20 were assessable for early metabolic response with FDG-PET. Of these, eight were classified as responders (40%) and 12 as nonresponders (60%). Early MR was significantly correlated to median time-to-tumor progression (TTP) with a median TTP for metabolic responders of 14 months versus 7 months for nonresponders (P = .02). No correlation was found between TTP and radiologic response evaluated by CT. Patients with a MR had a trend toward longer overall survival. Conclusion The use of MR evaluated by FDG-PET in the assessment of treatment efficacy in MPM appears promising. Our observations need to be validated in a larger prospective series.

Platinum Based Chemotherapy

Malignant pleural mesothelioma (MPM) is an aggressive disease with poor prognosis and the current treatment for early-stage MPM is based on a multimodality therapy regimen involving platinum-based chemotherapy preceding or following surgery. To enhance the cytoreductive role of surgery, some peri- or intra-operative intracavitary treatments have been developed, such as hyperthermic chemotherapy, but long-term results are weak. The aim of this study was to report the post-operative results and mid-term outcomes of our multimodal intention-to-treat pathway, including induction chemotherapy, followed by surgery and Hyperthermic Intraoperative THOracic Chemotherapy (HITHOC) in the treatment of early-stage epithelioid MPM. Since 2017, stage I or II epithelioid MPM patients have been inserted in a surgery-based multimodal approach comprising platinum-based induction chemotherapy, followed by pleurectomy and decortication (P/D) and HITHOC with cisplatin. The Kaplan–Meier method was used to estimate overall survival (OS), disease-free survival (DFS) and progression-free survival (PFS). During the study period, n = 65 patients affected by MPM were evaluated by our institutional Multidisciplinary Tumour Board; n = 12 patients with stage I-II who had no progression after induction chemotherapy underwent P/D and HITHOC. Post-operative mortality was 0, and complications developed in n = 7 (58.3%) patients. The median estimated OS was 31 months with a 1-year and 3-year OS of 100% and 55%, respectively. The median PFS was 26 months with 92% of a 1-year PFS, whereas DFS was 19 months with a 1-year DFS rate of 83%. The multimodal treatment of early-stage epithelioid MPM, including induction chemotherapy followed by P/D and HITHOC, was well tolerated and feasible with promising mid-term oncological results.

Malignant pleural mesothelioma (MPM) is a rare disease of the pleura and is largely related to asbestos exposure. Despite recent advancements in technologies and a greater understanding of the disease, the prognosis of MPM remains poor; the median overall survival rate is about 6 to 9 months in untreated patients. The main therapeutic strategies for MPM are surgery, chemotherapy, and radiation therapy (RT). The two main surgical approaches for MPM are extrapleural pneumonectomy (EPP), in which the lung is removed en bloc, and pleurectomy/decortication, in which the lung stays in situ. Chemotherapy usually consists of a platinum-based chemotherapy, such as cisplatin, often combined with a folate antimetabolite, such as pemetrexed. More recently, immunotherapy has emerged as a possible therapeutic strategy for MPM. Evidence suggests that single-modality treatments are not an effective therapeutic approach for MPM. Therefore, researchers have started to explore different multimodality treatment approaches, in which often combinations of surgery, chemotherapy, immunotherapy, and RT are investigated. There is still no definitive answer to the question of which multimodality treatment combinations are most effective in improving the poor prognosis of MPM. Research into the effects of trimodality treatment approaches have found that radical approaches such as EPP and hemithoracic RT post-EPP are less effective than was previously assumed. In general, there are still a great number of unanswered questions and unknown factors regarding the ideal treatment approach for MPM. Hopefully, more research into multimodality therapy will provide insight into which combination of treatment modalities is most effective.

8518 Background: Although pleurectomy/decortication (P/D) has become a preferred surgical technique for malignant pleural mesothelioma (MPM), only a few prospective, multi-center clinical trials have been conducted. Here we present final results of a nationwide, prospective, multi-institutional study to evaluate the feasibility of induction chemotherapy followed by P/D. Methods: Eligibility criteria: a histologically confirmed diagnosis of MPM; clinical T1–3, N0–2, M0 disease; no prior treatment for the disease; age between 20 and 75 years; ECOG performance status of 0 or 1; and written informed consent. Treatment methods: Induction chemotherapy of pemetrexed 500 mg/m2 plus cisplatin 75 mg/m2 for 3 cycles, followed by P/D. Intraoperative conversion from P/D to extrapleural pneumonectomy (EPP) was permitted. Pulmonary function tests were performed at 3, 6, 12, 24, and 36 months after surgery. Primary endpoint was macroscopic complete resection (MCR) rate regardless of the surgical technique. Results: Of 24 patients enrolled, 20 patients were eligible: median age 66 (48–74); M/F: 17/3, Clinical stage I/II/III: 8/9/3; Histology epi/sar/bi: 19/1/0. Two discontinued protocol before surgery due to deteriorated FEV1 or adverse effect (AE) of chemotherapy, and the remaining 18 patients completed surgery with MCR: P/D in 15 patients and EPP in 3. The trial met the primary endpoint with MCR rate of 90% (18/20). There was no treatment-related 30- and 90-day mortality. There were two cases of chemotherapy-related grade 4 AEs, but no surgery-related grade 4 AE occurred. The overall survival rates at 1 and 2 years and median survival time (MST) after registration were 95.0% (95% CI, 69.5 to 99.3), 70.0% (45.1 to 85.3), and 41.4 months (19.7 to NA), respectively. The progression-free survival rates at 1 and 2 years and MST after registration were 84.7% (60.0 to 94.8), 42.4% (20.5 to 62.7), and 22.9 months (12.7 to 28.4), respectively. Recurrence occurred in 17 patients, and initial relapse sites were local in 17 (100%) and distal in 6 (35.3%). The best values of FVC and FEV1 during postoperative period were 78.0% and 82.5% of preoperative values, respectively. Conclusions: Induction chemotherapy plus P/D yielded a MST over 40 months with acceptable risks. Postoperative pulmonary function was approximately 80% of preoperative value.

7708 Background: Examine the results of tri-modality therapy for malignant pleural mesothelioma (MPM). Methods: Protocol consisted of induction cisplatin-based chemotherapy, followed by extrapleural pneumonectomy (EPP) and adjuvant hemithoracic radiation therapy (RT) to 54 Gy. Results: A total of 60 patients were suitable candidates for tri-modality therapy between 01/2001 and 01/2007. Induction chemotherapy was administered to 56 patients; 4 patients underwent EPP without induction chemotherapy because of patient refusal (n=2), previous chemotherapy (n=1) and sarcomatoid MPM (n=1). Chemotherapy included vinorelbine/cisplatin (n=26), pemetrexed/cisplatin (n=26) and gemcitabine/cisplatin (n=4). EPP was performed in 47 patients; 13 patients did not undergo EPP because of tumor progression during chemotherapy (n=2), extensive chest wall involvement at surgery (n=6), or involvement of mediastinal lymph nodes at mediastinoscopy (n=5). Three patients (6%) died within 30 days of surgery. Pathological stage was II (n=6), III (n=35), and IV (n=6). Adjuvant RT was administered postoperatively to 36 patients and is ongoing in 5 patients; 6 patients did not receive adjuvant RT because of fatigue (n=5) or previous RT (n=1), and 4 patients did not complete RT up to 54 Gy. Overall survival for the 23 patients who completed the tri-modality therapy was 37% at 3 years with a median survival of 15 months. Eleven of the 23 patients had recurrence after a median of 8 months (range, 2–13 months). Recurrences were locoregional (n=2), in contralateral chest (n=3), abdomen (n=3), contralateral chest and abdomen (n=2), or pericardium (n=1). Among patients undergoing EPP, disease-free survival was longer in patients undergoing adjuvant high dose hemithoracic RT (p=0.07), in epithelial tumors (p=0.03), and in early stage (p=0.07). Overall survival was influenced by histology (p=0.007) and stage (p=0.05), but not by adjuvant high dose hemithoracic RT (p=0.5). The type of chemotherapy had no impact on disease-free and overall survival. Conclusions: Aggressive tri-modality therapy is feasible in selected patient with MPM. Adjuvant high dose hemithoracic RT can improve disease free survival and achieve good local control. No significant financial relationships to disclose.
