RESUMEN

(1) Background: Length of stay (LOS) has been suggested as a marker of the effectiveness of short-term care. Artificial Intelligence (AI) technologies could help monitor hospital stays. We developed an AI-based novel predictive LOS score for advanced-stage high-grade serous ovarian cancer (HGSOC) patients following cytoreductive surgery and refined factors significantly affecting LOS. (2) Methods: Machine learning and deep learning methods using artificial neural networks (ANN) were used together with conventional logistic regression to predict continuous and binary LOS outcomes for HGSOC patients. The models were evaluated in a post-hoc internal validation set and a Graphical User Interface (GUI) was developed to demonstrate the clinical feasibility of sophisticated LOS predictions. (3) Results: For binary LOS predictions at differential time points, the accuracy ranged between 70-98%. Feature selection identified surgical complexity, pre-surgery albumin, blood loss, operative time, bowel resection with stoma formation, and severe postoperative complications (CD3-5) as independent LOS predictors. For the GUI numerical LOS score, the ANN model was a good estimator for the standard deviation of the LOS distribution by ± two days. (4) Conclusions: We demonstrated the development and application of both quantitative and qualitative AI models to predict LOS in advanced-stage EOC patients following their cytoreduction. Accurate identification of potentially modifiable factors delaying hospital discharge can further inform services performing root cause analysis of LOS.

RESUMEN

Peritoneal metastasis (PM) in gastroenteropancreatic neuroendocrine tumors (GEP-NET) and hepato-pancreato-biliary (HPB) tumors has a low incidence and has rarely been studied as a stand-alone condition. The clinical relevance of PM in HPB tumors and GEP-NET arises from the fact that PM significantly worsens the prognosis of the underlying tumors. In GEP-NET, the particular situation is that PM has a negative prognostic impact compared to patients without metastases, which is not evident compared to patients with metastases in other locations. Complete surgical cytoreduction (CRS) is a curative treatment option for patients with PM in GEP-NET. Complete surgical resection should always be strived for, although patients may benefit from incomplete resection (70-90%) or resection of the primary tumor alone. Additional hyperthermic chemoperfusion (HIPEC) is currently not recommended. For nonresectable GEP-NET, systemic treatment is available that is oriented to the studies for generally metastasized GEP-NET. For PM in carcinomas of the bile duct and pancreatic carcinomas, there are no valid data or indications for CRS and HIPEC. In contrast, case series for PM in hepatocellular carcinoma (HCC) after CRS or CRS/HIPEC show good survival outcomes that justify a surgical approach under the condition of a complete resection. Patients with PM in GEP-NET and HCC should therefore be referred to a center for peritoneal tumor surgery to evaluate the option of complete CRS and use it as a curative option.

RESUMEN

Advanced high-grade serous (HGSC) ovarian cancer is treated with either primary surgery followed by chemotherapy or neoadjuvant chemotherapy followed by interval surgery. The decision to proceed with surgery primarily or after chemotherapy is based on a surgeon's clinical assessment and prediction of an optimal outcome. Optimal and complete cytoreductive surgery are correlated with improved overall survival. This clinical assessment results in an optimal surgery approximately 70% of the time. We hypothesize that this prediction can be improved by using biological tumor data to predict optimal cytoreduction. With access to a large biobank of ovarian cancer tumors, we obtained genomic data on 83 patients encompassing gene expression, exon expression, long non-coding RNA, micro RNA, single nucleotide variants, copy number variation, DNA methylation, and fusion transcripts. We then used statistical learning methods (lasso regression) to integrate these data with pre-operative clinical information to create predictive models to discriminate which patient would have an optimal or complete cytoreductive outcome. These models were then validated within The Cancer Genome Atlas (TCGA) HGSC database and using machine learning methods (TensorFlow). Of the 124 models created and validated for optimal cytoreduction, 21 performed at least equal to, if not better than, our historical clinical rate of optimal debulking in advanced-stage HGSC as a control. Of the 89 models created to predict complete cytoreduction, 37 have the potential to outperform clinical decision-making. Prospective validation of these models could result in improving our ability to objectively predict which patients will undergo optimal cytoreduction and, therefore, improve our ovarian cancer outcomes.

RESUMEN

AIM: This meta-analysis was conducted to evaluate the impact of BRCA mutations on survival outcomes of ovarian cancer patients and assess whether the BRCA status was an independent predictor of complete cytoreduction. METHODS: We searched the PubMed, Cochrane, EMBASE, Scopus, Web of Science, and Google Scholar databases for studies that evaluated the associations among BRCA mutations, ovarian cancer survival and surgical cytoreduction before August 2021 based on specific inclusion and exclusion criteria. RESULTS: We identified 61 articles that compared the clinical features, survival outcomes, and optimal surgical cytoreduction rates between BRCA-positive patients and BRCA-negative patients. The results showed that BRCA mutation carriers were diagnosed with ovarian cancer at a younger age than the age at which nonmutation carriers were diagnosed. In addition, BRCA mutation carriers were more likely to be in the International Federation of Gynecology and Obstetrics (FIGO) stage III-IV, and the pathological grade was commonly grade 3. The pathological type of BRCA mutation carriers was more likely to be high-grade serous carcinoma. Patients with BRCA mutations had higher response rates to platinum-based chemotherapy than the noncarriers. However, patients in both groups had equivalent rates of surgical cytoreduction, and BRCA-positive patients had longer overall survival (OS) time (HR = 0.65; 95% confidence interval [CI]: 0.59, 0.73; p < 0.001) and longer progression-free survival (PFS) (HR = 0.72; 95% CI: 0.63, 0.82; p < 0.001). CONCLUSION: BRCA mutations appear to be associated with improved OS and PFS in patients with ovarian cancer. However, we did not find any difference in the surgical resection rate between participants in the two groups.

RESUMEN

Neuroendocrine neoplasms of the small bowel are a diverse group of tumors with a broad spectrum of imaging findings and clinical implications. Most tumors originate in close proximity to the ileocecal valve and most commonly metastasize to the mesentery and liver. This review will highlight the imaging findings of primary and metastatic small bowel neuroendocrine neoplasm that are most relevant to the surgical team.

RESUMEN

OBJECTIVES: Low-grade serous ovarian cancer (LGSC) is a relatively chemo-resistant disease with limited effective treatment options for patients with recurrence. Secondary cytoreductive surgery (SCS) is commonly offered at recurrence, although any benefit this has on survival is not fully determined. This review evaluates the impact of SCS, including residual disease, on progression-free survival (PFS) and overall survival (OS) in recurrent LGSC. METHODS: A comprehensive search of Medline ALL, Embase Classic + Embase, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, and Web of Science was conducted to obtain studies evaluating optimal or complete SCS versus suboptimal SCS and the amount of residual disease in recurrent LGSC. Meta-analysis was performed and PFS and OS outcomes were calculated. RESULTS: 1Of 5296 studies screened, 350 progressed to full-text review, with 9 ultimately selected for inclusion in the systematic review. Two studies met criteria for meta-analysis of PFS and of OS. The presence of visible residual disease at the conclusion of SCS negatively impacted PFS (HR = 3.51, 95% CI = 1.72-7.14), whereas SCS with no residual disease significantly improved OS (HR = 0.4, 95% CI = 0.23-0.7) in patients with recurrent LGSC. Diffuse and extensive disease distribution was inversely linked to survival. In addition, SCS as an initial treatment for recurrent LGSC was associated with superior survival in comparison to chemotherapy. A short platinum-free interval was not associated with worse survival in this cohort. CONCLUSIONS: Complete SCS, and to a lesser extent optimal SCS, are associated with improved PFS and OS in patients with recurrent LGSC. SCS may be a better initial treatment strategy than systemic chemotherapy for recurrent disease. Patients with recurrent LGSC should be evaluated for the role of SCS based on disease distribution and functional status, irrespective of the platinum-free interval. Prospective studies are needed to further study the role of SCS in patients with recurrent LGSC.

RESUMEN

OBJECTIVE: To examine the role of non-exenterative secondary cytoreductive surgery (SCS) compared with non-surgical treatments and identify predictors of improved survival for patients with recurrent endometrial cancer (EC). METHODS: All patients undergoing primary surgical management for EC 1/1/2009-12/31/2017 who subsequently developed recurrence were retrospectively identified. Survival was determined from date of diagnosis of first recurrence to last follow-up and estimated using Kaplan-Meier method. Differences in survival were analyzed using Log-rank and Wald tests, based on Cox Proportional Hazards model. RESULTS: Among 376 patients with recurrent EC, median time to recurrence was 14.3 months (range, 0.2-102.2), post-recurrence median survival 29 months, median follow-up 29.2 months (range, 0-116). Sixty-one patients (16.2%) received SCS, 257 (68.4%) medical management (MM) (chemotherapy and/or radiation therapy), 32 (8.5%) hormonal therapy, 26 (6.9%) no further therapy. Patients selected for SCS were younger, had more endometrioid histology, more stage I disease at initial diagnosis, no residual disease after primary surgery, longer interval to first recurrence or progression, and the longest OS (57.6 months) (95% CI, 33.3-not reached). On multivariate analysis SCS was an independent predictor of improved survival. Among the 61 SCS patients, age < 70 at time of initial diagnosis, and endometrioid histology, were associated with improved post-relapse survival univariately (p = 0.008, 0.03, respectively). CONCLUSIONS: While MM was the most common treatment for first recurrence of EC, patients selected for surgery demonstrated the greatest survival benefit even after controlling for tumor size, site, histology, stage, time to recurrence. Careful patient selection and favorable tumor factors likely play a major role in improved outcomes. Surgical management should be considered whenever feasible in medically eligible patients, with additional consideration given to our suggested criteria.

RESUMEN

Achieving complete surgical cytoreduction in advanced stage high grade serous ovarian cancer (HGSOC) patients warrants an availability of Critical Care Unit (CCU) beds. Machine Learning (ML) could be helpful in monitoring CCU admissions to improve standards of care. We aimed to improve the accuracy of predicting CCU admission in HGSOC patients by ML algorithms and developed an ML-based predictive score. A cohort of 291 advanced stage HGSOC patients with fully curated data was selected. Several linear and non-linear distances, and quadratic discriminant ML methods, were employed to derive prediction information for CCU admission. When all the variables were included in the model, the prediction accuracies were higher for linear discriminant (0.90) and quadratic discriminant (0.93) methods compared with conventional logistic regression (0.84). Feature selection identified pre-treatment albumin, surgical complexity score, estimated blood loss, operative time, and bowel resection with stoma as the most significant prediction features. The real-time prediction accuracy of the Graphical User Interface CCU calculator reached 95%. Limited, potentially modifiable, mostly intra-operative factors contributing to CCU admission were identified and suggest areas for targeted interventions. The accurate quantification of CCU admission patterns is critical information when counseling patients about peri-operative risks related to their cytoreductive surgery.

RESUMEN

Epithelial ovarian cancer (EOC) is a common malignant disease, which remains asymptomatic for a prolonged period of time and is usually diagnosed at advanced stages. Cytoreductive surgery is a backbone of EOC treatment. Wherever possible, EOC patients are subjected to primary debulking surgery (PDS) with the aim to remove all visible tumor lumps. Some patients cannot undergo PDS due to extensive disease spread and/or high risk of perioperative morbidity, therefore they are subjected to neoadjuvant chemotherapy (NACT) before the surgery. Therapy given before surgery or as adjuvant treatment usually consists of combination of carboplatin and paclitaxel. Gemcitabine, topotecan, pegylated liposomal doxorubicin and poly ADP ribose polymerase inhibitors (PARPi) are commonly used for the management of EOC relapses. Consideration of BRCA1/2 germ-line and somatic status is getting increasingly important for the proper treatment planning.

RESUMEN

While ionizing radiotherapy (RT) can provide durable local control, the relative radiosensitivity of surrounding organs such as the lungs and heart and the distributed nature of the pleura limit the ability to safely deliver RT for patients with malignant pleural mesothelioma (MPM). Recent advances in the technological sophistication of RT planning and delivery devices have resulted in increased spatial control of irradiation dose that has extended the palliative and definitive applications of RT for patients with MPM. This review will outline the logistical, mechanistic and clinical basics of RT and the clinical trials supporting the use of RT in the multidisciplinary care of patients with MPM.

RESUMEN

PURPOSE: We sought to determine the level of concordance among surgeons' assessment of residual disease (RD) and pre-treatment computed tomography (CT) findings among women who underwent optimal surgical cytoreduction for advanced stage ovarian cancer. METHODS: This is a post-trial ad hoc analysis of a phase 3 randomized clinical trial evaluating the impact of bevacizumab in primary and maintenance therapy for patients with advanced stage ovarian cancer following surgical cytoreduction. All subjects underwent imaging of the chest/abdomen/pelvis to establish a post-surgical baseline prior to the initiation of chemotherapy. Information collected on trial was utilized to compare surgeon's operative assessment of RD, to pre-treatment imaging. RESULTS: Of 1873 enrolled patients, surgical outcome was described as optimal (RD≤1cm) in 639 subjects. Twelve patients were excluded as they did not have a baseline, pretreatment imaging, leaving 627 participants for analysis. The average interval from surgery to baseline scan was 26days (range: 1-109). In 251 cases (40%), the post-operative scan was discordant with surgeon assessment, demonstrating RD>1cm in size. RD>1cm was most commonly identified in the right upper quadrant (28.4%), retroperitoneal para-aortic lymph nodes (RD>1.5cm; 28.2%) and the left upper quadrant (10.7%). Patients with RD>1cm on pre-treatment CT (discordant) exhibited a significantly greater risk of disease progression (HR 1.30; 95% CI 1.08-1.56; p=0.0059). CONCLUSIONS: Among patients reported to have undergone optimal cytoreduction, 40% were found to have lesions >1cm on postoperative, pretreatment imaging. Although inflammatory changes and/or rapid tumor regrowth could account for the discordance, the impact on PFS and distribution of RD may suggest underestimation by the operating surgeon.

RESUMEN

A recent study reported an overall survival benefit for patients with metastatic urothelial carcinoma of the bladder (mUCB) managed with high-intensity local treatment (LT) of the primary tumor (chemotherapy plus radical cystectomy and/or radiation therapy ≥50Gy). Given the non-negligible morbidity of these procedures, adequate patient selection is crucial. Our objective was to identify patients who might benefit the most from high-intensity LT. Data for 3044 patients with mUCB at diagnosis were extracted from the National Cancer Data Base 2004-2013, and patients were categorized on the basis of treatment: high-intensity LT versus conservative LT (chemotherapy plus transurethral resection of bladder tumor and/or radiation therapy <50Gy). Multivariate Cox regression analysis predicted baseline 2-yr overall mortality (OM) risk among patients who received conservative LT. We then assessed the interaction between predicted OM risk and LT type. Compared to conservative LT, high-intensity LT yielded a higher observed OM-free survival rate among all patients with pure mUCB, irrespective of their predicted OM risk (nonsignificant interaction, p=0.7). These findings underline the need for further retrospective and prospective evaluation. PATIENT SUMMARY: Among patients with metastatic histologically pure urothelial carcinoma of the bladder, we found an overall survival benefit of high-intensity local treatment directed at the primary tumor, regardless of predicted baseline 2-yr overall mortality risk.

RESUMEN

OBJECTIVE: Surgical cytoreduction has been postulated to affect survival by increasing the efficacy of chemotherapy in ovarian cancer. We hypothesized that women with high-grade serous ovarian cancer, which usually responds to chemotherapy, would derive greater benefit from complete cytoreduction than those with histologic subtypes that are less responsive to chemotherapy, such as mucinous and clear cell carcinoma. METHODS: We conducted a retrospective cohort study of patients who underwent primary cytoreductive surgery and adjuvant chemotherapy for stage IIIC or IV epithelial ovarian cancer from 2011 to 2013 using data from the National Cancer Database. We constructed multivariable models to quantify the magnitude of associations between residual disease status (no residual disease, ≤1cm, or >1cm) and all-cause mortality by histologic type among women with clear cell, mucinous, and high-grade serous ovarian cancer. Because 26% of the sample had unknown residual disease status, we used multiple imputations in the primary analysis. RESULTS: We identified 6,013 women with stage IIIC and IV high-grade serous, 307 with clear cell, and 140 with mucinous histology. The association between residual disease status and mortality hazard did not differ significantly among histologic subtypes of ovarian cancer (p for interaction=0.32). In covariate adjusted models, compared to suboptimal cytoreduction, cytoreduction to no gross disease was associated with a hazard reduction of 42% in high-grade serous carcinoma (hazard ratio [HR]=0.58, 95% confidence interval [CI]=0.49-0.68), 61% in clear cell carcinoma (HR=0.39, 95% CI=0.22-0.69), and 54% in mucinous carcinoma (HR=0.46, 95% CI=0.22-0.99). CONCLUSIONS: We found no evidence that surgical cytoreduction was of greater prognostic importance in high-grade serous carcinomas than in histologies that are less responsive to chemotherapy.

RESUMEN

OBJECTIVES: To assess the perioperative outcomes of minimal access surgery (MAS) in secondary surgical cytoreduction (SSCR) for recurrent epithelial ovarian cancer (ROC); to compare oncologic outcomes with laparotomy (LAP). METHODS: Using an institutional database, we identified all patients with ROC undergoing SSCR from 1/5/09-6/14/14. Selection for MAS or LAP was based on surgeon preference. To minimize selection bias, preoperative imaging was reviewed for all LAP cases. In this manner, we identified potential MAS candidates, who were used in the comparison. Intent-to-treat analyses were undertaken using statistical testing. RESULTS: 170 cases were identified (131 LAP, 8 LSC, 31 RBT). 68/131 (52%) LAP cases were deemed potential candidates for MAS. Feasibility analyses included 68 LAP and 39 MAS cases. Six (15%) MAS cases were converted to LAP. Median age, BMI, operative time did not differ significantly between the groups. Complete gross resection was achieved in 37/39 (95%) MAS, 63/68 (93%) LAP (P=1.0). Median estimated blood loss was 50cm3 (range, 5-500) MAS, 150cm3 (range, 0-1500) LAP (P=0.001). Median length of stay was 1day (range, 0-23) MAS, 5days (range, 1-21) LAP (P<0.001). Complications occurred in 3/39 (8%) MAS, 15/68 (22%) LAP (P=0.06). The 2-year progression-free survival was 56.1% (SE 9%) MAS, 63.5% (SE 6%) LAP (P=1.0). The 2-year overall survival was 92.2% (SE 5.4%) MAS, 81.4% (SE 5.5%) LAP (P=0.7). CONCLUSIONS: MAS for SSCR is feasible in properly selected cases. MAS is associated with favorable perioperative outcomes and similar oncologic outcomes, compared to LAP.

RESUMEN

AIM: The primary objective of the study was to evaluate the overall survival of women with advanced stage (Stage IIIA-IV) high-grade serous ovarian cancer in Macedonia. MATERIALS AND METHODS: The study was a cross-sectional medical record review of patients diagnosed with advanced stage HGSC. Patients were deemed eligible for inclusion if they were diagnosed with an advanced stage (Stage IIIA-IV) HGSC of the ovary, fallopian tube or peritoneum between 2009 and 2015. The data were analyzed in a descriptive fashion and summary statistics were provided, as appropriate. Survival was calculated using the Kaplan-Meier method. RESULTS: A total of 81 eligible patients were identified and included in the study. The average overall survival in the studied cohort was 46.59 months (95%CI = 39.11-54.06). Patients that were optimally debulked and patients that had a platinum-free interval larger than 12 months had significantly longer survival in the current series (p < 0.001). CONCLUSION: the average overall survival of advanced stage HGSC patients in the studied series was 46.59 months (95%CI = 39.11-54.06). Patients aged 65 years or younger tended to live approximately ten months longer than patients older than 65 years, but this difference was not statistically significant. There was no difference in HGSC survival in the groups of patients with grade 2 and grade 3 disease. However, optimal surgical debulking and platinum sensitivity were associated with significantly better overall survival.

RESUMEN

OBJECTIVE: High-grade serous carcinoma (HGSC) generally presents at an advanced stage with poor long-term (LT) survival. Here we describe clinical features found in women surviving HGSC for ten or more years. METHODS: A multi-center research consortium was established between five participating academic centers. Patient selection criteria included high-grade serous ovarian, fallopian tube, or peritoneal carcinoma with at least ten years of follow up. Non-serous, borderline tumors and low-grade serous subtypes were excluded. RESULTS: The 203 identified LT ten-year survivors with HGSC were diagnosed at a median age of 57years (range 37-84years). The majority of patients had stage IIIC (72.4%) disease at presentation. Of those who underwent primary cytoreductive surgery, optimal cytoreduction was achieved in 143 (85.6%) patients. After a median follow up of 144months, 88 (46.8%) patients did not develop recurrent disease after initial treatment. Unexpected findings from this survey of LT survivors includes 14% of patients having had suboptimal cytoreduction, 11% of patients having an initial platinum free interval of <12months, and nearly 53% of patients having recurrent disease, yet still surviving more than ten years after diagnosis. CONCLUSIONS: LT survivors of HGSC of the ovary generally have favorable clinical features including optimal surgical cytoreduction and primary platinum sensitive disease. The majority of patients will develop recurrent disease, however many remained disease free for more than 10years. Future work will compare the clinical features of this unusual cohort of LT survivors with the characteristics of HGSC patients having less favorable outcomes.

RESUMEN

BACKGROUND: Encouraging results on survival of patients with malignant peritoneal mesothelioma have been shown with the use of cytoreductive surgery and perioperative intraperitoneal chemotherapy. This study explores the impact of aggressive surgical treatment on overall survival of peritoneal mesothelioma. METHODS: This is a retrospective analysis of prospectively collected clinical data of all patients with diagnosis of malignant peritoneal mesothelioma treated in a designated referral centre in Greece. All patients were offered cytoreductive surgery and intraperitoneal chemotherapy. Patient's characteristics, operative reports, pathology reports, and discharge summaries were stored in an electronic database and later reviewed and analysed. RESULTS: Cytoreduction for peritoneal mesothelioma was performed on 20 patients (15 men and 5 women) with a mean age of 59.4 years (SD 16.1). Mean peritoneal cancer index was 16.1 (SD 10.4) and the median completeness of cytoreduction score was 2 (range 1-2). Mean overall survival was 46.8 months (SE 4.03) with a mean of 21.4 and median of 18 months of follow-up. Disease-specific survival was 100% for the observed period. Univariate analysis showed the completeness of cytoreduction as the only possible predictor of survival. A median of 10 (range 4-14) peritonectomy procedures were performed per patient. Median hospital stay was 14 (range 10-57 days). Grade III and IV complications occurred post-operatively in 5 patients (25%). Two patients died in the post-operative period of pulmonary embolism and myocardial infarction. CONCLUSION: Cytoreductive surgery with HIPEC has proved the most effective treatment even when taking account of the cost of significant morbidity.

RESUMEN

Epithelial ovarian carcinoma consists of several subtypes, including high-grade and low-grade serous carcinoma. In the recent past, women with all subtypes of epithelial ovarian carcinoma have been treated similarly and are included in the same clinical trials. However, a distinction has emerged between the type I, low-grade tumors and the type 2, higher-grade epithelial malignancies. Low-grade serous carcinoma exhibits different molecular and clinical features from the other epithelial subtypes, as well as some degree of chemotherapy resistance. This review summarizes the genetic, molecular and clinical characteristics of low-grade serous disease and provides an appraisal of the management strategies.

RESUMEN

Recent studies suggest that immunotherapy may offer a promising treatment strategy for early-stage malignant pleural mesothelioma (MPM), but advanced tumor burden may limit the efficacy of immunotherapy. Therefore, we hypothesized that surgical cytoreduction could restore the efficacy of vaccine-based immunotherapy for MPM. We developed a murine model of MPM through transduction of a mesothelioma cell line with mesothelin. We used this model to evaluate the efficacy of a Listeria monocytogenes vaccine expressing mesothelin. Tumor growth was significantly inhibited at four weeks in animals vaccinated two weeks prior to tumor cell inoculation as compared to those given an empty vector control (1371 ± 420 mm(3) versus 405 ± 139 mm(3); p < 0.01). Mice vaccinated one week prior to tumor challenge also displayed significant reduction in tumor volume (1227 ± 406 mm(3) versus 309 ± 173 mm(3); p < 0.01). The vaccine had no effect when administered concurrently with tumor challenge, or after tumors were established. Flow cytometry showed reduced mesothelin expression in large tumors, as well as tumor-associated immunosuppression due to increased myeloid derived suppressor cells (MDSCs). These factors may have limited vaccine efficacy for advanced disease. Surgical cytoreduction of established tumors restored the antitumor potency of the therapeutic vaccine, with significantly reduced tumor burden at post-operative day 18 (397 ± 103 mm(3) versus 1047 ± 258 mm(3); p < 0.01). We found that surgery reduced MDSCs to levels comparable to those in tumor-naïve mice. This study demonstrates that cytoreduction surgery restores the efficacy of cancer vaccines for MPM by reducing tumor-related immunosuppression that impairs immunotherapy.
