Outcomes of Patients Undergoing Segmentectomy for Occult Node-Positive Clinical Stage IA Lung Cancer. Ann Thorac Surg 2024; 118:655-663. [PMID: 38866198 PMCID: PMC11347119 DOI: 10.1016/j.athoracsur.2024.05.031] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/18/2024] [Revised: 05/03/2024] [Accepted: 05/20/2024] [Indexed: 06/14/2024]
Abstract
BACKGROUND Results of recent clinical trials suggest that segmentectomy may be an acceptable alternative to lobectomy for selected patients with early-stage non-small cell lung cancer (NSCLC). Increased use of segmentectomy may result in a concomitant increase in occult node-positive (N+) disease on surgical pathology examination. The optimal management for such patients remains unknown. METHODS Clinicopathologic data were abstracted from a prospective institutional database to identify patients with pathologic N+ disease after segmentectomy for cT1 N0 M0 NSCLC. Propensity score matching identified a comparable lobectomy cohort for assessment of cumulative incidence of recurrence and overall survival (OS). RESULTS Of 759 included patients, 27 (4%) had nodal upstaging on the final pathology report. Of these 27 patients, 4 (15%) had skip metastasis to N2 stations, and 20 (74%) received adjuvant therapy; no completion lobectomies were performed. Ten patients (37%) had disease recurrence: 3 isolated locoregional (11%) and 7 distant (26%). The median time to recurrence among patients with recurrence was 1.8 years; OS after recurrence was 3.4 years. After 5:1 matching with 109 patients who underwent lobectomy, all variables were balanced between the groups, except pathologic N2 stage and open surgical approach. The 5-year cumulative incidence of recurrence was not significantly different between segmentectomy and lobectomy (42% vs 52%, respectively; Gray's P = .1). The 5-year OS (63% and 50%) and rate of locoregional recurrence (12% vs 13%) were not statistically different between the groups. CONCLUSIONS Patients with occult N+ disease after segmentectomy for cT1 N0 M0 NSCLC had limited isolated locoregional recurrences and outcomes similar to those in patients who underwent lobectomy. Lobectomy may not provide an advantage in these patients.

Abstract
OBJECTIVE MIS (VATS, RATS) for pulmonary resection is standard in early stage NSCLC as it is associated with better perioperative outcomes than thoracotomy. MIS for resection of more advanced NSCLC (Stages IB-IIIB) treated with neoadjuvant therapy has been utilized. However, the determinants of success are not well-defined. METHODS A single institution retrospective review of a prospectively maintained database was conducted, querying for patients with clinical Stage IB-IIIB NSCLC who had resection after neoadjuvant systemic therapy without radiation from 2013-2022. Patients were grouped by surgical approach, open vs. MIS. Successful MIS was defined by no conversion, R0 resection, and no major (≥grade 3) morbidity. Analyses by intent-to-treat assessed outcomes by Wilcoxon rank sum test and Fisher's exact test. (MVA identified variables that contributed to successful MIS resection. RESULTS Of 627 eligible patients, 360 (57%) had open and 267 (43%) had MIS procedures. Most patients (79.1%) received neoadjuvant platinum-based chemotherapy, and 21.9% were treated with immunotherapy or targeted therapy alone or combined with chemotherapy. Among MIS resections, 179 (67%) were performed by VATS and 88 (33%) by RATS. The conversion rate was 16% (n=43). Successful MIS resection was achieved in 77% of patients. MVA showed that pre-treatment clinical N stage was a significant determinant of success, but not pre-treatment clinical T stage or type of neoadjuvant therapy. CONCLUSION Following neoadjuvant systemic therapy for clinical stage IB-IIIB NSCLC, MIS resection can be successfully accomplished and should be considered in appropriate patients. Presence of pre-treatment nodal disease is associated with higher odds of conversion, major morbidity, and incomplete resection.

Abstract
The International Association for the Study of Lung Cancer collaborated with the International Mesothelioma Interest Group to propose the first TNM stage classification system for diffuse pleural mesothelioma in 1995, accepted by the Union for International Cancer Control and the American Joint Committee on Cancer for the sixth and seventh edition stage classification manuals. The International Association for the Study of Lung Cancer Staging and Prognostic Factors Committee Mesothelioma Domain developed and analyzed an international registry of patients with pleural mesothelioma and updated TNM descriptors for the eighth edition of the stage classification system. To inform revisions for the forthcoming ninth edition of the TNM stage classification system, data submission was solicited for patients diagnosed between 2013 and 2022 with expanded data elements on the basis of the first project's exploratory analyses, including pleural thickness measurements, updated surgical nomenclature, and molecular markers. The resulting database consisted of a total of 3598 analyzable cases from Europe, Australia, Asia, North America, and South America, with a median age of 71 years (range: 18-99 y), 2775 (77.1%) of whom were men. With only 1310 patients (36.4%) undergoing curative-intent operations, this iteration of the database includes far more patients treated nonsurgically compared with prior. Four separate manuscripts on T, N, M, and stage groupings submitted to this journal will summarize analyses of these data and will serve collectively as the primary source of the proposed changes to the upcoming ninth edition of the pleural mesothelioma stage classification system.

Abstract
INTRODUCTION The TNM classification of lung cancer is periodically revised. The International Association for the Study of Lung Cancer collected and analyzed a new database to inform the forthcoming ninth edition of the TNM classification. The results are herewith presented. METHODS After exclusions, 76,518 patients from a total of 124,581 registered patients were available for analyses: 58,193 with clinical stage, 39,192 with pathologic stage, and 62,611 with best stage NSCLC. The proposed new N2 subcategories (N2a, involvement of single ipsilateral mediastinal or subcarinal nodal station, and N2b, involvement of multiple ipsilateral mediastinal nodal stations with or without involvement of the subcarinal nodal station) and the new M1c subcategories (M1c1, multiple extrathoracic metastases in one organ system, and M1c2, multiple extrathoracic metastases in multiple organ systems) were considered in the survival analyses. Several potential stage groupings were evaluated, using multiple analyses, including recursive partitioning, assessment of homogeneity within and discrimination between potential groups, clinical and statistical significance of survival differences, multivariable regression, and broad assessment of generalizability. RESULTS T1N1, T1N2a, and T3N2a subgroups are assigned to IIA, IIB, and IIIA stage groups, respectively. T2aN2b and T2bN2b subgroups are assigned to IIIB. M1c1 and M1c2 remain in stage group IVB. Analyses reveal consistent ordering, discrimination of prognosis, and broad generalizability of the proposed ninth edition stage classification of lung cancer. CONCLUSIONS The proposed stages for the ninth edition TNM improve the granularity of nomenclature about anatomic extent that has benefits as treatment approaches become increasingly differentiated and complex.

Abstract
OBJECTIVE There is a lack of knowledge regarding the use of prognostic features in stage I lung adenocarcinoma (LUAD). Thus, we investigated clinicopathologic features associated with recurrence after complete resection for stage I LUAD. METHODS We performed a retrospective analysis of patients with pathologic stage I LUAD who underwent R0 resection from 2010 to 2020. Exclusion criteria included history of lung cancer, induction or adjuvant therapy, noninvasive or mucinous LUAD, and death within 90 days of surgery. Fine and Gray competing-risk regression assessed associations between clinicopathologic features and disease recurrence. RESULTS In total, 1912 patients met inclusion criteria. Most patients (1565 [82%]) had stage IA LUAD, and 250 developed recurrence: 141 (56%) distant and 109 (44%) locoregional only. The 5-year cumulative incidence of recurrence was 12% (95% CI, 11%-14%). Higher maximum standardized uptake value of the primary tumor (hazard ratio [HR], 1.04), sublobar resection (HR, 2.04), higher International Association for the Study of Lung Cancer grade (HR, 5.32 [grade 2]; HR, 7.93 [grade 3]), lymphovascular invasion (HR, 1.70), visceral pleural invasion (HR, 1.54), and tumor size (HR, 1.30) were independently associated with a hazard of recurrence. Tumors with 3 to 4 high-risk features had a higher cumulative incidence of recurrence at 5 years than tumors without these features (30% vs 4%; P < .001). CONCLUSIONS Recurrence after resection for stage I LUAD remains an issue for select patients. Commonly reported clinicopathologic features can be used to define patients at high risk of recurrence and should be considered when assessing the prognosis of patients with stage I disease.

Abstract
INTRODUCTION Electronic nose (E-nose) technology has reported excellent sensitivity and specificity in the setting of lung cancer screening. However, the performance of E-nose specifically for early-stage tumors remains unclear. Therefore, the aim of our study was to assess the diagnostic performance of E-nose technology in clinical stage I lung cancer. METHODS This phase IIc trial (NCT04734145) included patients diagnosed with a single greater than or equal to 50% solid stage I nodule. Exhalates were prospectively collected from January 2020 to August 2023. Blinded bioengineers analyzed the exhalates, using E-nose technology to determine the probability of malignancy. Patients were stratified into three risk groups (low-risk, [<0.2]; moderate-risk, [≥0.2-0.7]; high-risk, [≥0.7]). The primary outcome was the diagnostic performance of E-nose versus histopathology (accuracy and F1 score). The secondary outcome was the clinical performance of the E-nose versus clinicoradiological prediction models. RESULTS Based on the predefined cutoff (<0.20), E-nose agreed with histopathologic results in 86% of cases, achieving an F1 score of 92.5%, based on 86 true positives, two false negatives, and 12 false positives (n = 100). E-nose would refer fewer patients with malignant nodules to observation (low-risk: 2 versus 9 and 11, respectively; p = 0.028 and p = 0.011) than would the Swensen and Brock models and more patients with malignant nodules to treatment without biopsy (high-risk: 27 versus 19 and 6, respectively; p = 0.057 and p < 0.001). CONCLUSIONS In the setting of clinical stage I lung cancer, E-nose agrees well with histopathology. Accordingly, E-nose technology can be used in addition to imaging or as part of a "multiomics" platform.

Abstract
INTRODUCTION The eighth edition of the TNM classification of pleural mesothelioma (PM) saw substantial changes in T and N components and stage groupings. The International Association for the Study of Lung Cancer collected data into a multinational database to further refine this classification. This ninth edition proposal incorporates changes proposed in the clinical (c)T component but not the pathologic T component, to include size criteria, and further refines TNM stage groupings for PM. METHODS Data were submitted through electronic data capture or batch transfer from institutional databases. Survival was measured from diagnosis date. Candidate stage groups were developed using a recursive partitioning and amalgamation algorithm applied to all cM0 cases for clinical stage and subsequently for pathologic stage. Cox models were developed to estimate survival for each stage group. RESULTS Of 3598 submitted cases, 2192 were analyzable for overall clinical stage and 445 for overall pathologic stage. Recursive partitioning and amalgamation generated survival tree on overall survival outcomes restricted to cM0, with newly proposed (ninth edition) cT and cN component-derived optimal stage groupings of stage I (T1N0), II (T1N1; T2N0), IIIA (T1N2; T2N1/2; any T3), IIIB (any T4), and IV (any M1). Although cT and pathologic T descriptors are different in the ninth edition, aligning pathologic stage groupings with clinical stage produced better discrimination than did retaining eighth edition pathologic stage groupings. CONCLUSIONS To our knowledge, this revision of the clinical TNM classification for PM is the first to incorporate the measurement-based proposed changes in cT category. The pathologic TNM aligns with clinical TNM.

Abstract
INTRODUCTION The International Association for the Study of Lung Cancer developed an international database to inform potential revisions in the ninth edition of the TNM classification of diffuse pleural mesothelioma (PM). This study analyzed the clinical and pathologic N categories to determine whether revisions were indicated relative to the eighth edition staging system. METHODS Of 7338 PM cases diagnosed from 2013 to 2022 and 3598 met all inclusion criteria for planned analyses. Data on 2836 patients without metastases were included in this study. Overall survival (OS) was measured from date of diagnosis. Patients were included regardless of whether they received neoadjuvant treatment. For the pathologic N analysis, patients who underwent resection (extrapleural pneumonectomy or pleurectomy/decortication) were included. N subgroups were analyzed and OS assessed by the Kaplan-Meier method. RESULTS The existing eighth edition N categories were performed adequately in the ninth edition data set. A median OS advantage was noted for clinical and pathologic N0 versus N1 patients: 23.2 versus 18.5 and 33.8 versus 25.0 months, respectively. Patients with resected pN0 had a 3-year OS of 48%. No difference in OS was noted for single- versus multiple-station nodal metastases. The number of nodal stations sampled at the time of resection was not associated with a difference in OS. CONCLUSIONS Data regarding clinical and pathologic N categories corroborate those used in the eighth edition. No changes in the N categories are recommended in the ninth edition of PM staging system.

Abstract
Neoadjuvant immunotherapy has gone from an idea to an indication in locally advanced lung cancer. Several phase III trials have demonstrated the superiority of neoadjuvant chemoimmunotherapy compared with chemotherapy in this setting. Although such progress has revolutionized the treatment of locally advanced disease, the unmet needs of stage I and stage II patients without lymph node disease have largely been underrepresented in existing trials. Up-front resection with few patients going on to complete adjuvant therapy remains the norm for most stage I and II patients. Emerging evidence now supports the exploration of supplemental checkpoint blockade in well-selected early-stage, node-negative patients with large tumors and no actionable driver mutations. Although concerns surrounding safety and risk exist, patient selection could be substantially improved using novel biomarker approaches that leverage our understanding of the tumor immune microenvironment of lung cancer. This review provides a comprehensive overview of the opportunities and controversies of perioperative immunotherapy in node-negative lung cancer.

Abstract
INTRODUCTION The primary tumor (T) component in the eighth edition of pleural mesothelioma (PM) staging system is based on pleural involvement and extent of invasion. Quantitative assessment of pleural tumor has been found to be prognostic. We explored quantitative and qualitative metrics to develop recommendations for T descriptors in the upcoming ninth edition of the PM staging system. METHODS The International Association for the Study of Lung Cancer prospectively collected data on patients with PM. Sum of maximum pleural thickness (Psum) was recorded. Optimal combinations of Psum and eighth edition cT descriptors were assessed using recursive binary splitting algorithm, with bootstrap resampling to correct for the adaptive nature of the splitting algorithm, and validated in the eighth edition data. Overall survival (OS) was calculated by the Kaplan-Meier method and differences in OS assessed by the log-rank test. RESULTS Of 7338 patients submitted, 3598 were eligible for cT analysis and 1790 had Psum measurements. Recursive partitioning identified optimal cutpoints of Psum at 12 and 30 mm, which, in combination with extent of invasion, yielded four prognostic groups for OS. Fmax greater than 5 mm indicated poor prognosis. cT4 category (based on invasion) revealed similar performance to eighth edition. Three eighth edition descriptors were eliminated based on low predictive accuracy. Eighth edition pT descriptors remained valid in ninth edition analyses. CONCLUSION Given reproducible prognostication by Psum, size criteria will be incorporated into cT1 to T3 categories in the ninth edition. Current cT4 category and all pT descriptors will be maintained, with reclassification of fissural invasion as pT2.

Abstract
BACKGROUND The objective of this study is to determine the outcomes and toxicities of patients with malignant pleural mesothelioma (MPM) treated with stereotactic body radiotherapy (SBRT). MATERIALS AND METHODS Data were extracted from an institutional tumor registry for patients diagnosed with mesothelioma and treated with SBRT. Kaplan-Meier and Cox regression analyses were employed to determine local control (LC) and overall survival (OS). RESULTS Forty-four patients with 59 total treated tumors from December 2006 to April 2022 were identified. Fifty-one (86.4 %) cases had oligoprogressive disease (five sites or less). The median prescription dose delivered was 3000 cGy in 5 fractions (range: 2700-6000 cGy in 3-8 fractions). Fifty-one (86.4 %) tumors were in the pleura, 4 (6.8 %) spine, 2 (3.4 %) bone, 1 (1.7 %) brain, and 1 (1.7 %) pancreas. The median follow-up from SBRT completion for those alive at last follow-up was 28 months (range: 14-52 months). The most common toxicities were fatigue (50.8 %), nausea (22.0 %), pain flare (15.3 %), esophagitis (6.8 %), dermatitis (6.8 %), and pneumonitis (5.1 %). There were no grade ≥ 3 acute or late toxicities. There were 2 (3.4 %) local failures, one of the pleura and another of the spine. One-year LC was 92.9 % (95 % CI: 74.6-98.2 %) for all lesions and 96.3 % (95 % CI: 76.5-99.5 %) for pleural tumors. One-year LC was 90.9 % (95 % CI: 68.1-97.6 %) for epithelioid tumors and 92.1 % (95 % CI: 72.1-98.0 %) for oligoprogressive tumors. One-year OS from time of SBRT completion was 36.4 % (95 % CI: 22.6-50.3 %). On multivariable analysis, KPS was the lone significant predictor for OS (p = 0.029). CONCLUSIONS Our single-institutional experience on patients with MPM suggests that SBRT is safe with a low toxicity profile and potentially achieve good local control.

Abstract
OBJECTIVE To investigate the association between operative time and postoperative outcomes. BACKGROUND The association between operative time and morbidity after pulmonary lobectomy has not been characterized fully. METHODS Patients who underwent pulmonary lobectomy for primary lung cancer at our institution from 2010 to 2018 were reviewed. Exclusion criteria included clinical stage ≥IIb disease, conversion to thoracotomy, and previous ipsilateral lung treatment. Operative time was measured from incision to closure. Relationships between operative time and outcomes were quantified using multivariable mixed-effects models with surgeon-level random effects. RESULTS In total, 1651 patients were included. The median age was 68 years (interquartile range, 61-74), and 63% of patients were women. Median operative time was 3.2 hours (interquartile range, 2.7-3.8) for all cases, 3.0 hours for open procedures, 3.3 hours for video-assisted thoracoscopies, and 3.3 hours for robotic procedures ( P =0.0002). Overall, 488 patients (30%) experienced a complication; 77 patients (5%) had a major complication (grade ≥3), and 5 patients (0.3%) died within 30 days of discharge. On multivariable analysis, operative time was associated with higher odds of any complication [odds ratio per hour, 1.37; 95% confidence interval (CI), 1.20-1.57; P <0.0001] and major complication (odds ratio per hour, 1.41; 95% CI, 1.21-1.64; P <0.0001). Operative time was also associated with longer hospital length of stay (β, 1.09; 95% CI, 1.04-1.14; P =0.001). CONCLUSIONS Longer operative time was associated with worse outcomes in patients who underwent lobectomy. Operative time is a potential risk factor to consider in the perioperative phase.

Abstract
INTRODUCTION The International Association for the Study of Lung Cancer developed an international pleural mesothelioma database to improve staging. Data entered from 1995 to 2009 (training data set) were analyzed previously to evaluate supplemental prognostic factors. We evaluated these factors with new clinical data to determine whether the previous models could be improved. METHODS Patients entered into the database from 2009 to 2019 (validation cohort) were assessed for the association between previous prognosticators and overall survival using Cox proportional hazards regression with bidirectional stepwise selection. Additional variables were analyzed and models were compared using Harrell's C-index. RESULTS The training data set included 3101 patients and the validation cohort, 1733 patients. For the multivariable pathologic staging model applied to the training cohort, C-index was 0.68 (95% confidence interval [CI]: 0.656-0.705). For the validation data set (n = 497), C-index was 0.650 (95% CI: 0.614-0.685), and pathologic stage, histologic diagnosis, sex, adjuvant therapy, and platelet count were independently associated with survival. Adding anemia to the model increased the C-index to 0.652 (95% CI: 0.618-0.686). A basic presentation model including all parameters before staging yielded a C-index of 0.668 (95% CI: 0.641-0.695). In comparison, the European Organization for Research and Treatment of Cancer model yielded C-indices of 0.550 (95% CI: 0.511-0.589) and 0.577 (95% CI: 0.550-0.604) for pathologic staging and presentation models, respectively. CONCLUSIONS Although significant predictors differed slightly, the International Association for the Study of Lung Cancer training model performed well in the validation set and better than the model of the European Organization for Research and Treatment of Cancer. International collaboration is critical to improve outcomes in this rare disease.

Abstract
OBJECTIVE Despite neoadjuvant chemoradiotherapy, Pancoast tumors still present surgical and oncologic challenges. To optimize outcomes, we used a multidisciplinary care paradigm with medical and radiation oncology, and involvement of spine neurosurgery for most T3 and all T4 tumors. Spine neurosurgery permitted resection of transverse process for T3 and vertebral body resection for T4 tumors. METHODS Retrospective analysis of single institution, prospective database of patients undergoing resection for cT3 4M0 Pancoast tumors. Patients were grouped as cT3 with combined resection with spine neurosurgery (T3 Neuro), cT3 without spine neurosurgery (T3 NoNeuro), and cT4. Overall survival, progression-free survival were analyzed by Kaplan-Meier and compared between groups using log-rank test. Cumulative incidence of local-regional and distant recurrence were compared using Gray test. P value <.05 was considered significant. RESULTS From 2000 to 2021, 155 patients underwent surgery: median age was 58 years, and 81 were (52%) men. Most patients received neoadjuvant platinum-based neoadjuvant chemoradiotherapy (n = 127 [82%]). Operations were 48 cT3 Neuro, 41 cT3 NoNeuro, 66 cT4. R0 resection was achieved in 49 (94%) cT3 NoNeuro, 35 (85%) cT3 Neuro, and 57 (86%) cT4 patients (P = .4). Complete or major pathologic response occurred in 71 (55%) patients. Lower local-regional cumulative incidence was seen in cT3 Neuro versus cT3 NoNeuro (P = .05) and after major pathologic response. Overall survival and progression-free survival were associated with complete response, pathologic stage, and nodal status but not cT category. CONCLUSIONS This treatment paradigm was associated with a high frequency of R0 resection, complete response, and major pathologic response. cT3 and cT4 tumors had similar outcomes. Novel therapies are needed to improve complete response.

Abstract
OBJECTIVES The aim of this study was to compare postoperative outcomes between biologic and synthetic reconstructions after chest wall resection in a matched cohort. METHODS All patients who underwent reconstruction after full-thickness chest wall resection from 2000 to 2022 were reviewed and stratified by prosthesis type (biologic or synthetic). Biologic prostheses were of biologic origin or were fully absorbable and incorporable. Integer matching was performed to reduce confounding. The study end point was surgical site complications requiring reoperation. Multivariable analysis was performed to identify associated risk factors. RESULTS In total, 438 patients underwent prosthetic chest wall reconstruction (unmatched: biologic, n = 49; synthetic, n = 389; matched: biologic, n = 46; synthetic, n = 46). After matching, the median (interquartile range) defect size was 83 cm2 (50-142) for the biologic group and 90 cm2 (48-146) for the synthetic group (P = 0.97). Myocutaneous flaps were used in 33% of biologic reconstructions (n = 15) and 33% of synthetic reconstructions (n = 15) in the matched cohort (P = 0.99). The incidence of surgical site complications requiring reoperation was not significantly different between biologic and synthetic reconstructions in the unmatched (3 [6%] vs 29 [7%]; P = 0.99) and matched (2 [4%] vs 4 [9%]; P = 0.68) cohorts. On the multivariable analysis, operative time [adjusted odds ratio (aOR) = 1.01, 95% confidence interval (CI), 1.00-1.01; P = 0.006] and operative blood loss (aOR = 1.00, 95% CI, 1.00-1.00]; P = 0.012) were associated with higher rates of surgical site complications requiring reoperation; microvascular free flaps (aOR = 0.03, 95% CI, 0.00-0.42; P = 0.024) were associated with lower rates. CONCLUSIONS The incidence of surgical site complications requiring reoperation was not significantly different between biologic and synthetic prostheses in chest wall reconstructions.

Abstract
OBJECTIVE To investigate the utility of serum soluble mesothelin-related peptide (SMRP) and tumor mesothelin expression in the management of esophageal adenocarcinoma (ADC). BACKGROUND Clinical management of esophageal ADC is limited by a lack of accurate evaluation of tumor burden, treatment response, and disease recurrence. Our retrospective data showed that tumor mesothelin and its serum correlate, SMRP, are overexpressed and associated with poor outcomes in patients with esophageal ADC. METHODS Serum SMRP and tumoral mesothelin expression from 101 patients with locally advanced esophageal ADC were analyzed before induction chemoradiation (pretreatment) and at the time of resection (posttreatment), as a biomarker for treatment response, disease recurrence, and overall survival (OS). RESULTS Pre and posttreatment serum SMRP was ≥1 nM in 49% and 53%, and pre and post-treatment tumor mesothelin expression was >25% in 35% and 46% of patients, respectively. Pretreatment serum SMRP was not significantly associated with tumor stage ( P = 0.9), treatment response (radiologic response, P = 0.4; pathologic response, P = 0.7), or recurrence ( P =0.229). Pretreatment tumor mesothelin expression was associated with OS (hazard ratio: 2.08; 95% CI: 1.14-3.79; P = 0.017) but had no statistically significant association with recurrence ( P = 0.9). Three-year OS of patients with pretreatment tumor mesothelin expression of ≤25% was 78% (95% CI: 68%-89%), compared with 49% (95% CI: 35%-70%) among those with >25%. CONCLUSIONS Pretreatment tumor mesothelin expression is prognostic of OS for patients with locally advanced esophageal ADC, whereas serum SMRP is not a reliable biomarker for monitoring treatment response or recurrence.
