Abstract
BACKGROUND Select patients with peritoneal metastases are treated with cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CRS/HIPEC). We assayed for intra- and interpatient drug response heterogeneity through testing of patient-derived tumor organoids (PDTOs). METHODS PDTOs were generated from CRS/HIPEC patients from December 2021 to September 2022 and subjected to an in vitro HIPEC drug screen. Drug response was assessed with a cell viability assay and cleaved caspase-3 staining. RESULTS A total of 31 patients were consented for tissue collection. Viable tissue was harvested from 23, and PDTO generation was successful in 13 (56%). PDTOs were analyzed from six appendiceal, three colorectal, two small bowel, one gastric, and one adrenal tumor. Drug screen results were generated in as few as 7 days (62%), with an average time of 12 days. Most patients received mitomycin-C (MMC) intraoperatively (n = 9); however, in only three cases was this agent considered the optimal choice in vitro. Three sets of PDTOs were resistant (defined as > 50% PDTO viability) to all agents tested and two were pan-sensitive (defined as 3 or more agents with < 50% PDTO viability). In three patients, organoids were generated from multiple metastatic sites and intrapatient drug response heterogeneity was observed. CONCLUSIONS Both intra- and interpatient drug response heterogeneity exist in patients undergoing CRS/HIPEC for nongynecologic abdominal cancers. Caution must be used when interpreting patient response to chemotherapeutic agents based on a single site of testing in those with metastatic disease.

Ann Surg Oncol 2024; 31:1980-1989. [PMID: 38044348 DOI: 10.1245/s10434-023-14577-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/21/2023] [Accepted: 10/27/2023] [Indexed: 12/05/2023]
Abstract
BACKGROUND Cytoreductive surgery with hyperthermic intraperitoneal chemotherapy (CRS-HIPEC) is the preferred treatment for select patients with peritoneal malignancies. However, the procedure is resource intensive and costly. This study aimed to determine the risk of financial toxicity for patients undergoing CRS-HIPEC. PATIENTS AND METHODS We performed a retrospective cohort study of patients undergoing CRS-HIPEC at a single institution from 2016 to 2022. We utilized insurance status, out-of-pocket expenditures, and estimated post-subsistence income to determine risk of financial toxicity. A multivariable logistic regression was used to determine risk factors for financial toxicity. RESULTS Our final study cohort consisted of 163 patients. Average age was 58 [standard deviation 10] years, and 52.8% (n = 86) were male. A total of 52 patients (31.9%) were at risk of financial toxicity. A total of 36 patients (22.1%) were from the lower income quartiles (first or second) and 127 patients (77.9%) were from the higher income quartiles (third or fourth). A total of 47 patients (29%) were insured by Medicare, and 116 patients (71%) had private insurance. The median out-of-pocket expenditure across the study cohort was $3500, with a median of $5000 ($3341-$7350) for the at-risk group and $3341 ($2500-$4022) for the not at-risk group (p < 0.001). Risk factors for financial toxicity included high out-of-pocket expenditures and a lower income quartile. CONCLUSIONS An estimated one-third of patients undergoing CRS-HIPEC at our institution were at risk for financial toxicity. Several preoperative factors were associated with an increased risk and could be utilized to identify patients who might benefit from interventions.

Abstract
INTRODUCTION Malign peritoneal mesothelioma (MPM) is an uncommon disease that is difficult to treat. Cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CRS-HIPEC) are the gold standards for treating MPM. Sometimes extreme cytoreductive surgery (eCRS) is required to achieve complete cytoreduction, which is one of the most important prognostic factors. There is limited information in the literature about the contribution of eCRS in patients with MPM. In this study, we aimed to investigate the impact of eCRS on survival and perioperative outcomes. METHODS The Department of Surgical Oncology at Cumhuriyet University database was retrospectively reviewed for MPM patients who underwent CRS-HIPEC between January 2004 and December 2018. Patients who underwent CRS-HIPEC were divided into eCRS and less extensive CRS (leCRS) groups. A resection of ≥5 organs or ≥3 small bowel anastomoses were defined as eCRS. Both groups were compared regarding survival, demographic information, and perioperative outcomes. RESULTS A total of 31 patients were included. eCRS-HIPEC was used in 15 patients. Complete cytoreduction (CC score 0/1) was achieved in all 31 patients. Compared to leCRS, the eCRS group had a longer median length of stay, longer intensive care unit stay, a higher median peritoneal cancer index (PCI), higher intraoperative blood loss, more frequent occurrence of any complication, and a longer operative time (all p values < 0.001). Clavien Dindo 3-4 complications, ASA, and gender were similar in both groups of patients (p > 0.05). It was found that there was no significant difference between the OS of the eCRS and leCRS groups (37.5 vs. 42.8 months, p = 0.895). CONCLUSIONS Rates of serious complications and morbidity are similar in patients undergoing eCRS compared to leCRS. In patients with high PCI and multiorgan involvement, complete cytoreduction can be achieved by performing eCRS, and survival results equivalent to those with low PCI can be achieved.

Abstract
INTRODUCTION Peritoneal mesothelioma (PM) is a rare malignancy originating from the peritoneal lining. Cytoreductive surgery (CRS) and heated intraperitoneal chemotherapy (HIPEC) is the standard-of-care for patients with isolated PM. Due to a paucity of prospective data there are several different HIPEC protocols. The aims of this study are to describe the CRS and HIPEC protocols for PM and patient outcomes across Canada. METHODS A multicenter retrospective study was performed on patients diagnosed and treated for PM with CRS and HIPEC in four major peritoneal disease centers in Canada between 2000 and 2021. Data on patient characteristics, treatment patterns, postoperative morbidity, recurrence, and survival were collected. RESULTS A total of 72 patients were identified. Mean age was 52 years (17-75) and 37.5% were male. Epithelioid (70.1%) and multicystic (13%) mesothelioma were the most common subtypes. Twenty-one patients (30%) were treated with neoadjuvant chemotherapy. CRS and HIPEC was performed in 64 patients (91.4%). Of these, the mean PCI was 22 (2-39) and cisplatin+doxorubicin was the most common HIPEC regimen (n = 33, 51.6%). A semi-closed coliseum technique was used in 68.8% of HIPECs and the mean duration of surgery was 486 min (90-1052). Clavien-Dindo III or IV complications occurred in 12 patients (16.9%). With a median follow-up of 24 months (0.2-104.4), we found a 5-year overall survival of 61% and a 5-year recurrence-free survival of 35%. CONCLUSION CRS and HIPEC is a safe and effective treatment modality for well-selected patients with PM, with some achieving prolonged survival.

Abstract
Diffuse malignant peritoneal mesothelioma (DMPM) prognosis was improved by the locoregional treatment combining cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC). HIPEC is a multiparametric treatment with multiple protocols proposed and reviewed in this work. A systematic review of medical literature was performed according to PRISMA guidelines. The search strategy used "malignant peritoneal mesothelioma" and "HIPEC" as keywords in three databases. Studies were included if reporting precisely the HIPEC regimen and the related outcomes, if comparing regimen, or if reporting national/international guidelines. The GRADE methodology was used to rate the level of evidence. Twenty-eight studies were included in this review: 1 was a meta-analysis, 18 reported cohort outcomes, 4 retrospectively compared HIPEC regimens, and 5 were guidelines. Six HIPEC regimens were found, 4 with one drug (cisplatin, mitomycine-C, carboplatin, oxaliplatin), 2 using two drugs (cisplatin-doxorubicin or cisplatin-mitomycine-C). Cisplatin, up to 250 mg/m2 over 90 min, appeared as the key HIPEC drug with a toxicity profile well controlled by the concomitant intravenous perfusion of sodium thiosulfate. Comparative studies tended to show that a bi-drug regimen led to better long-term oncologic outcomes, with cisplatin 50 mg/m2 plus doxorubicin 15 mg/m2 being safe and more efficient. This late protocol was the most widely used and recommended in 3 out of 4 international guidelines. Cisplatin was the preferred drug for HIPEC in DMPM patients. Most of the time, it was combined with doxorubicin for 90 min. A harmonization of protocols and further comparative studies are needed to optimize HIPEC regimen choice.

Abstract
PURPOSE Imaging of the peritoneum and related pathology is a challenge. Among peritoneal diseases, malignant peritoneal mesothelioma (MPeM) is an uncommon tumor with poor prognosis. To date, there are no specific guidelines or imaging protocols dedicated for the peritoneum and MPeM. The objective of this study was to analyze the literature describing imaging modalities used for MPeM to determine their relative clinical efficacy and review commonly reported imaging features of MPeM to promote standardized reporting. METHODS We performed a systematic review of original research articles discussing imaging modalities in MPeM from 1999 to 2020. Effectiveness measures and common findings were compared across imaging modalities. RESULTS Among 582 studies analyzed, the most-used imaging modality was CT (54.3%). In the differentiation of MPeM from peritoneal carcinomatosis, one study found CT had a diagnostic sensitivity of 53%, specificity of 100%, and accuracy of 68%. Two studies found fluorodeoxyglucose positron emission tomography (FDG-PET) had sensitivity of 86-92%, specificity of 83-89%, and accuracy of 87-89%. Another study found magnetic resonance imaging (MRI) was the best predictor of the peritoneal carcinomatosis index. Characteristics shown to best differentiate MPeM from other diseases included ascites, peritoneal thickening, mesenteric thickening, pleural plaques, maximum tumor dimension, and number of masses. CONCLUSION Most published MPeM imaging studies utilized CT. PET/CT or MRI appear promising, and future studies should compare effectiveness of these modalities. MPeM imaging reports should highlight ascites, number of and maximum tumor dimension, peritoneal/mesenteric thickening, and associated pleural plaques, allowing for better aggregation of MPeM imaging data across studies.

Abstract
BACKGROUND Malignant peritoneal mesothelioma is a rare disease with poor outcomes. Cytoreductive surgery with hyperthermic intraperitoneal chemotherapy is the cornerstone of therapy. We aim to compare outcomes of malignant peritoneal mesothelioma treated at academic versus community hospitals. METHODS This was a retrospective cohort study using the National Cancer Database to identify patients with malignant peritoneal mesothelioma from 2004 to 2016. Patients were divided according to treating facility type: academic or community. Outcomes were assessed using log-rank tests, Cox proportional-hazard modeling, and Kaplan-Meier survival statistics. RESULTS In total, 2682 patients with malignant peritoneal mesothelioma were identified. A total of 1272 (47.4%) were treated at an academic facility and 1410 (52.6%) were treated at a community facility. Five hundred forty-six (42.9%) of patients at academic facilities underwent debulking or radical surgery compared to 286 (20.2%) at community facilities. Three hundred sixty-six (28.8%) of patients at academic facilities received chemotherapy on the same day as surgery compared to 147 (10.4%) of patients at community facilities. Unadjusted 5-year survival was 29.7% (95% CI 26.7-32.7) for academic centers compared to 18.3% (95% CI 16.0-20.7) for community centers. In multivariable analysis, community facility was an independent predictor of increased risk of death (HR: 1.19, 95% CI 1.08-1.32, p = 0.001). CONCLUSIONS We demonstrate better survival outcomes for malignant peritoneal mesothelioma treated at academic compared to community facilities. Patients at academic centers underwent surgery and received chemotherapy on the same day as surgery more frequently than those at community centers, suggesting that malignant peritoneal mesothelioma patients may be better served at experienced academic centers.

Abstract
Epithelioid mesothelioma is the most prevalent subtype of diffuse malignant peritoneal mesothelioma. A recently described nuclear-grading system predicted survival in patients with epithelioid malignant pleural mesothelioma. The present study was undertaken to validate this grading system in epithelioid malignant peritoneal mesothelioma (EMPM) and to compare to combined grade, including nuclear atypia, mitotic count, and tumor necrosis. Cases of EMPM, from 1995 to 2018, were analyzed from 7 French institutions from RENAPE network. Solid growth, tumor necrosis, nuclear atypia, and mitotic count were evaluated by at least 3 pathologists from the RENAPATH group. The predictions in terms of OS and PFS of nuclear grade and combined grade were analyzed. Nuclear grade was computed combining nuclear atypia score and mitotic count into a grade of I-III. Another system combining nuclear atypia score, mitotic score, and tumor necrosis was evaluated and defined as a combined grade I-III. A total of 138 cases were identified. The median follow-up was 38.9 months (range: 1.1-196.6). Nuclear and combined grades III were independently associated with a shorter OS (p < 0.05), and a shorter PFS (p < 0.05). Patients with combined grade I tumors had the best overall and progression-free survivals, in comparison to nuclear grade I. In this large multicentric study, combined grade and nuclear grade were the best independent predictors of OS and PFS in EMPM. These systems should be easily described by pathologists involved into the management of malignant peritoneal mesothelioma, because of their potential therapeutic implications.

Abstract
The prognosis of peritoneal carcinomatosis is poor. However, the emergence of cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CRS + HIPEC) as a treatment option has prolonged survival and it can even potentially cure patients with peritoneal carcinomatosis. Randomized controlled studies and other observational studies indicated that this combined therapy potentially improved the prognosis of patients with colon, gastric, and ovarian cancers with acceptable morbidity and mortality rates. Even in rarer diseases, such as pseudomyxoma peritonei and malignant peritoneal mesothelioma, CRS + HIPEC markedly improved the prognoses over those with conventional treatment. Based on the accumulated evidence, clinical guidelines recommend CRS + HIPEC for selected patients with peritoneal carcinomatosis. However, several issues still need to be overcome. A standard method for HIPEC has not yet been established. Furthermore, the criteria employed for patient selection need to be clarified to achieve real benefits. The peritoneal cancer index, chemo-sensitivity and several biological markers are considered to be key factors.

CRS/HIPEC with Major Organ Resection in Peritoneal Mesothelioma Does not Impact Major Complications or Overall Survival: A Retrospective Cohort Study of the US HIPEC Collaborative.

Abstract
INTRODUCTION CRS/HIPEC is thought to confer a survival advantage for patients with malignant peritoneal mesothelioma (MPM). However, the impact of nonperitoneal organ resection is not clearly defined. We evaluated the impact of major organ resection (MOR) on postoperative outcomes and overall survival (OS). PATIENTS AND METHODS The US HIPEC collaborative database (2000-2017) was reviewed for MPM patients who underwent CRS/HIPEC. MOR was defined as total or partial resection of diaphragm, stomach, spleen, pancreas, small bowel, colon, rectum, kidney, ureter, bladder, and/or uterus. MOR was categorized as 0, 1, or 2+ organs. RESULTS A total of 174 patients were identified. Median PCI was 16 (3-39). The distribution of patients with MOR-0, MOR-1, and MOR-2+ was 94, 45, and 35 patients, respectively. MOR-1 and MOR-2+ groups had a higher frequency of any complication compared with MOR-0 (57.8%, 74.3%, and 48.9%, respectively, p = 0.035), but Clavien 3/4 complications were similar. Median length of stay was slightly higher in the MOR-1 and MOR-2+ groups (10 and 11 days) compared with the MOR-0 cohort (9 days, p = 0.005). Incomplete cytoreduction, ASA class 4, and male gender were associated with increased mortality on unadjusted analysis; however, their impact on OS was attenuated on multivariable analysis. MOR was not associated with OS based on these data (MOR-1: HR 1.67, 95% CI 0.59-4.74; MOR-2+ : HR 0.77, 95% CI 0.22-2.69). CONCLUSIONS MOR was not associated with an increase in major complications or worse OS in patients undergoing CRS/HIPEC for MPM and should be considered, if necessary, to achieve complete cytoreduction for MPM patients.

Repurposing Quinacrine for Treatment of Malignant Mesothelioma: In-Vitro Therapeutic and Mechanistic Evaluation. Int J Mol Sci 2020; 21:ijms21176306. [PMID: 32878257 PMCID: PMC7503636 DOI: 10.3390/ijms21176306] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/08/2020] [Revised: 08/26/2020] [Accepted: 08/26/2020] [Indexed: 02/07/2023] Open
Abstract
Malignant mesothelioma (MM) is a rare type of cancer primarily affecting mesothelial cells lining the pleural cavity. In this study, we propose to repurpose quinacrine (QA), a widely approved anti-malarial drug, for Malignant Pleural Mesothelioma (MPM) treatment. QA demonstrates high degree of cytotoxicity against both immortalized and primary patient-derived cell lines with sub-micromolar 50% inhibitory concentration (IC50) values ranging from 1.2 µM (H2452) to 5.03 µM (H28). Further, QA also inhibited cellular migration and colony formation in MPM cells, demonstrated using scratch and clonogenic assays, respectively. A 3D-spheroid cell culture experiment was performed to mimic in-vivo tumor conditions, and QA was reported to be highly effective in this simulated cellular model. Anti-angiogenic properties were also discovered for QA. Autophagy inhibition assay was performed, and results revealed that QA successfully inhibited autophagy process in MPM cells, which has been cited to be one of the survival pathways for MPM. Annexin V real-time apoptosis study revealed significant apoptotic induction in MPM cells following QA treatment. Western blots confirmed inhibition of autophagy and induction of apoptosis. These studies highlight anti-mesothelioma efficacy of QA at low doses, which can be instrumental in developing it as a stand-alone treatment strategy for MPM.

Abstract
Hysterectomy and bilateral salpingo-oophorectomy in non-gynecologic HIPEC cases improves cytoreductive surgery efforts. Metastatic lesions often involve the pelvic organs on final pathology despite pre-operative and intraoperative findings. Hysterectomy and bilateral salpingo-oophorectomy adds minimal morbidity to the procedure.
Hyperthermic intraperitoneal chemotherapy (HIPEC) is a key component of treatment in non-gynecologic peritoneal surface malignancies. As many as 10–15% of patients with a gastrointestinal primary malignancy will present with carcinomatosis. Maximal cytoreductive surgery directly affects the prognosis of patients. The routine inclusion of hysterectomy with bilateral salpingo-oophorectomy during these procedures optimizes cytoreduction despite negative pre-operative imaging and findings at the time of surgery. In this case series, we review twenty non-gynecologic cancer patients who underwent cytoreductive surgery with concurrent hysterectomy and bilateral salpingo-oophorectomy and HIPEC at our institution.

Abstract
Peritoneal surface oncology has emerged as a subspecialty of surgical oncology, with the growing popularity of surgical treatment of peritoneal metastases comprising of cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC). Pathological evaluation plays a key role in multidisciplinary management but there are still many areas where there are no guidelines or consensus on reporting. Some tumors presenting to a peritoneal surface oncology unit are rare and pathologists my not be familiar with diagnosing and classifying those. In this manuscript, we have reviewed the evidence regarding various aspects of histopathological evaluation of peritoneal tumors. It includes establishing a diagnosis, appropriate classification and staging of common and rare tumors and evaluation of pathological response to chemotherapy. In many instances, the information captured is of prognostic value alone with no direct therapeutic implications. But proper capturing of such information is vital for generating evidence that will guide future treatment trends and research. There are no guidelines/data set for reporting cytoreductive surgery specimens. Based on the authors' experience, a format for handling/grossing and synoptic reporting of these specimens is provided.

Abstract
BACKGROUND The surgical peritoneal cancer index (sPCI) is calculated based on a subjective evaluation of the extent of peritoneal disease during surgery. The pathologic PCI (pPCI) may be a more accurate and objective method for determining the PCI. This study aimed to compare the sPCI and pPCI and to study the potential pitfalls and clinical implications of using the pPCI. METHODS This prospective study (July to December 2018) included all patients undergoing cytoreductive surgery (CRS). The pPCI was calculated for each patient and compared with the sPCI. The impact of potential confounding factors on the difference between pPCI and sPCI was evaluated. RESULTS Among 191 patients undergoing CRS at four centers, the pPCI and sPCI were concordant for 37 patients (19.3%). The pPCI was lower than the sPCI for 125 patients (65.4%) and higher for 29 patients (15.1%). The concordance between the two groups was maximum for gastric cancer (38.8%) and colorectal cancer (27.6%) and least for mesothelioma (6.7%) and rare primary tumors (5.6%) (p = 0.04). The difference was 0 to 3 points for 119 patients (62.3%), 4 to 5 points for 27 patients (14.1%), and more than 5 points for 45 patients (23.5%). The rate of concordance was not influenced by the use of neoadjuvant chemotherapy (NACT) (p = 0.4), but the difference was greater when NACT was used (p = 0.03). CONCLUSIONS The pPCI strongly differs from the sPCI for patients undergoing CRS for peritoneal disease and may provide a more accurate evaluation of the peritoneal disease extent. Further studies are needed to determine its prognostic value compared with sPCI, and consensus guidelines are needed for calculating it.

Abstract
Malignant peritoneal mesothelioma (MPM) is a rare and lethal disease of the peritoneal lining, with high variability in biologic aggressiveness. Morbidity and mortality of the disease are related to progressive locoregional effects within the abdominal cavity, such as distention, pain, early satiety, and decreased oral intake that can ultimately lead to bowel obstruction and cachexia. The standard of care for patients with resectable disease remains cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CRS-HIPEC), with potential survival outcomes greater than 5 years in appropriately selected patients. Patients with inoperable MPM can be offered systemic treatment, although the disease is usually refractory to standard chemotherapic regimens. Patients with MPM should be treated at high volume centers with strong consideration for inclusion in tumor registries and clinical trials. In 2020, research will continue to explore promising genetic and immunologic targets and focus on refinement of surgical methods to optimize CRS-HIPEC approaches.

Abstract
INTRODUCTION Diffuse malignant peritoneal mesothelioma (DMPM) is a rare malignancy associated with poor outcomes. Recent reports have shown longer survival with radical surgery, usually combined with intraperitoneal chemotherapy. However, surgical interventions in these patients have not been extensively studied at a population level. The objective of this retrospective cohort study is to assess the prevalence of surgical and nonsurgical interventions for DMPM patients, the influence of surgery on survival outcomes, and the associations between demographic and clinical factors with treatments and outcomes. METHODS This study included adult patients diagnosed with DMPM from 2003 to 2014 and registered in the National Cancer Database (NCDB). The primary outcome was overall survival. Histologically confirmed mesothelioma was defined using International Classification of Diseases (ICD)-3 codes 9050/3, 9051/3, 90523, and 9053/3 and peritoneum as primary affected organ using ICD codes C17-19, C22-24, C26, C42, C48, and C76. Relationships between demographic and clinical variables, surgical treatments, and survival outcomes were evaluated using logistic and Cox modeling and log-rank tests. RESULTS A total of 2062 patients were identified, of whom 1055 (51%) did not receive any surgery while 701 (34%) received radical surgery. Patients receiving radical surgery had overall survival of 38.4 months compared with 7.1 months for patients without surgery (p < 0.001) and 41.8 months in patients who received both radical surgery and systemic chemotherapy. CONCLUSIONS Patients selected for and treated with radical surgery had significantly better overall survival compared with those receiving nonsurgical treatment. Patients newly diagnosed with DMPM should be evaluated for the possibility of receiving radical surgery.

Abstract
PURPOSE Cytoreductive surgery with intraoperative hyperthermic intraperitoneal chemotherapy is standard of care for diffuse malignant peritoneal mesothelioma (DMPM), but there is variability among institutions in the administration of adjuvant chemotherapy. Characterization of the largest series of DMPM patients treated at a single institution and identification of the demographic, disease, and treatment factors associated with overall survival were sought. PATIENTS AND METHODS All DMPM patients who underwent initial cytoreductive surgery with the intention to undergo intraperitoneal chemotherapy and a second-look operation from 1995 to 2016 at our institution were retrospectively reviewed. The primary endpoint was overall survival. RESULTS A total of 204 DMPM patients underwent initial cytoreduction. Median overall survival was 32 months from initial cytoreduction. Independent baseline prognostic factors of improved overall survival were female sex, age < 60 years, and epithelioid histology. Independent treatment factors associated with improved overall survival were attempted resection at initial operation, residual disease < 0.5 cm at the end of the initial operation, and dwell intraperitoneal chemotherapy. CONCLUSIONS Cytoreductive surgery with intraoperative and dwell intraperitoneal chemotherapy is a feasible approach for DMPM. Expanded access to these therapies may offer benefit to a larger population of patients. Demographic and operative parameters associated with overall survival in this large cohort are consistent with previous reports. In the context of this treatment protocol, dwell intraperitoneal chemotherapy is associated with longer overall survival.

Abstract
Introduction: The surgical arm of the Mesothelioma and Radical Surgery (MARS) trial involved a multimodal approach, with combined therapy consisting of chemotherapy, complete gross resection, and radiation therapy. However, the MARS trial did not compare surgery with chemotherapy, and the survival and quality of life outcomes of this trial's surgical arm were inferior to those of the non-surgical arm. Methods for achieving complete gross resection (macroscopic complete response [MCR]) include extrapleural pneumonectomy (EPP), wherein the pleura, lung, diaphragm, and pericardium are removed en bloc, and pleurectomy/decortication (P/D), wherein the affected lung is preserved. Nonetheless, the most effective therapy remains unclear.Areas covered: Here, surgery post-neoadjuvant chemotherapy for malignant pleural mesothelioma with either EPP or P/D has been discussed, along with trimodal and bimodal therapies.Expert opinion: With the development of post-P/D radiation therapy, it is currently possible to truly compare EPP with P/D. Moreover, R0 resection cannot be achieved with either EPP or P/D; thus, both must incorporate debulking, although the two procedures are largely incompatible. Therefore, there is a need to rebuild the status of surgery as a multimodal therapy.

Abstract
El mesotelioma peritoneal es una neoplasia que se origina en las células mesoteliales del peritoneo. Históricamente, la supervivencia de los pacientes con mesotelioma peritoneal maligno sin tratamiento, es menor de 12 meses y se considera una neoplasia resistente a la quimioterapia. La citorreducción quirúrgica y la quimioterapia regional administrada como quimioterapia hipertérmica intraperitoneal (Hyperthermic Intraperitoneal Chemotherapy, HIPEC) se asocia con mejor supervivencia a largo plazo.
Se presenta el caso de un paciente con antecedentes de exposición al asbesto y con diagnóstico de mesotelioma peritoneal maligno de tipo epitelioide, que fue tratado con cirugía citorreductora más quimioterapia hipertérmica intraperitoneal en el Instituto Nacional de Cancerología con una supervivencia de un año libre de enfermedad.
