A CT-based novel model to predict pathological complete response of locally advanced esophageal squamous cell carcinoma to neoadjuvant PD-1 blockade in combination with chemotherapy. Eur J Radiol 2023; 167:111065. [PMID: 37651827 DOI: 10.1016/j.ejrad.2023.111065] [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: 03/30/2023] [Revised: 08/08/2023] [Accepted: 08/24/2023] [Indexed: 09/02/2023]
Abstract
PURPOSE To develop a novel CT-based model to predict pathological complete response (pCR) of locally advanced esophageal squamous cell carcinoma (ESCC) to neoadjuvant PD-1 blockade in combination with chemotherapy. METHODS 117 consecutive patients with locally advanced ESCC were stratified into training cohort (n = 82) and validation cohort (n = 35). All patients underwent non-contrast and contrast-enhanced thoracic and upper abdominal CT before neoadjuvant PD-1 blockade in combination with chemotherapy (CTpre), and after two cycles of the therapy before esophagectomy (CTpost), respectively. Univariate analyses and binary logistic regression analyses of ESCC quantitative and qualitative CT features were performed to determine independent predictors of pCR. Prediction performance of the model developed with independent predictors from training cohort was evaluated by receiver operating characteristic (ROC) analysis, and validated by Kappa test in validation cohort. RESULTS In training cohort, the difference in CT attenuation between tumor and background normal esophageal wall obtained from CTpre (ΔTNpre), tumoral increased CT attenuation after contrast-enhanced scan from CTpost images (ΔTpost) and gross tumor volume (GTV) from CTpre were independent predictors of pCR (odds ratio = 1.128 (95% confidence interval (CI): 0.997-1.277), 1.113 (95%CI: 0.965-1.239) and 1.133 (95%CI: 1.043-1.231), respectively, all P-values < 0.05). Logistic regression model equation (0.121 × ΔTNpre + 0.107 × ΔTpost + 0.125 × GTV - 9.856) to predict pCR showed the best performance with an area under the ROC of 0.876, compared with each independent predictor. The good performance was confirmed by the Kappa test (K-value = 0.796) in validation cohort. CONCLUSIONS This novel model can be reliable to predict pCR to neoadjuvant PD-1 blockade in combination with chemotherapy in locally advanced ESCC.

Abstract
PURPOSE Cancer cachexia, a complex multifactorial syndrome associated with sarcopenia, negatively affects the quality of life and survival in patients with several cancers. We aimed to develop a new score for cachexia assessment and evaluate its effectiveness in the classification of patients undergoing radical resection for colorectal cancer. METHODS This study included 396 patients who underwent radical resection for Stage I-III colorectal cancer. To develop the Cancer Cachexia Score (CCS), we analyzed predictive factors of cachexia status related to the development of sarcopenia and incorporated significant factors into the score. We then evaluated the relationship between CCS and survival after radical resection for colorectal cancer. RESULTS As body mass index (P < 0.001), prognostic nutritional index (P = 0.005), and tumor volume (P < 0.001) were significantly associated with the development of sarcopenia, these factors were included in CCS. Using CCS, 221 (56%), 98 (25%), and 77 (19%) patients were diagnosed with mild, moderate, and severe cancer cachexia, respectively. In multivariate analysis, severe CCS (P < 0.001), N stage 1-2 (P < 0.001), and occurrence of postoperative complications (P = 0.007) were independent predictors of disease-free survival. Age ≥ 65 years (P = 0.009), severe CCS (P < 0.001), and N stage 1-2 (P < 0.001) were independent predictors of overall survival. CONCLUSIONS CCS may be a useful prognostic factor for predicting poor survival after radical resection in patients with Stage I-III colorectal cancer.

Fibrous dressing containing bioactive glass with combined chemotherapy and wound healing promotion for post-surgical treatment of melanoma. BIOMATERIALS ADVANCES 2023; 149:213387. [PMID: 36990026 DOI: 10.1016/j.bioadv.2023.213387] [Citation(s) in RCA: 7] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/28/2022] [Revised: 03/02/2023] [Accepted: 03/11/2023] [Indexed: 03/18/2023]
Abstract
Surgery is the mainstream treatment for melanoma. However, inappropriate post-surgical treatment could result in the tumor recurrence and sever tissue damage, which ultimately leads to the failure of therapy and significantly compromises the therapeutic outcome of surgery. Herein, taking advantages of the co-axial electrospinning technology, we construct a dual-function nanofibrous wound dressing for the post-surgical treatment of melanoma. Si-Ca-P-based mesoporous bioactive glass (MBG) was prepared by the template-sol-gel process, with the compositions being set as 60 SiO2: 36 CaO: 4 P2O5 in mol%. Through rational design, 5-fluorouracil (5-FU)-loaded MBG nanoparticles (MBG-U) are successfully incorporated into the fiber core with biodegradable poly(lactic-co-glycolic acid) (PLGA) as the cladding layer to form the core-shell nanofibers (MBG-U CSF), which achieves sustained releases of chemotherapeutic drug (i.e.,5-FU) and wound healing promotion function. Thereafter, the post-surgical melanoma model was established to evaluate the in-situ anti-cancer and wound healing effect of MBG-U CSF. Thereafter, the post-surgical melanoma model was established to evaluate the anti-cancer and wound healing effect. The results demonstrated that the core-shell nanofibrous dressing almost complete suppressed tumor growth, and simultaneously promoted skin regeneration, which provides a promising strategy for the post-surgical treatment for melanoma.

Abstract
Aim: To evaluate the clinical outcome and elucidate the prognostic factors in patients with esophageal squamous cell carcinoma (ESCC) treated with definitive chemoradiotherapy (CRT). Patients: Data for patients newly diagnosed with ESCC receiving definitive CRT at our institution between 2012 and 2018 were retrospectively reviewed. Results: A total of 201 patients were included. Severe stenosis after radiotherapy was an independent factor relevant to prognosis. Maximal esophageal wall thickness, short-term responses, severe stenosis at diagnosis and a high neutrophil-to-lymphocyte ratio were independent risk factors for the occurrence of severe stenosis after radiotherapy. Conclusion: Severe stenosis after radiotherapy is a useful predictive indicator in patients with ESCC receiving definitive CRT. Further studies are needed to verify these findings.

Abstract
The present study aimed to evaluate the chemopreventive potential of Pinus roxburghii branch (P. roxburghii) and Nauplius graveolens (N. graveolens) extracts against human colorectal cancer (CRC) induced by C26 murine cells in a BALB/c mouse model. Real-time qRT-PCR was used to evaluate the apoptotic pathway by measuring the relative mRNA expression levels of the Bcl-2, Bax, Cas3, NF-κB, and PI3k genes. At the termination of the 30-day period, blood samples were collected to assay the biomarkers. The results showed a significant increase (p < 0.05) in the levels of TGF-β, CEA, CA19-9, malondialdehyde, ALT, AST, ALP, urea, and creatinine in the positive control compared to the negative control group. In addition, the glutathione reductase activity and total antioxidant activity were reduced in the positive control compared to the negative control. The biomarkers mentioned above were restored to almost normal levels after administering a safe dose (1/10) of a lethal dose of P. roxburghii and N. graveolens extracts. Administration of one-tenth of the LD50 of P. roxburghii and N. graveolens extracts caused a significant upregulation of the expression of Bax and Cas-3 and downregulation of the Bcl-2, NF-ĸB, and PI3k genes vs. the GAPDH gene as a housekeeping gene compared to the control group. Furthermore, the Bax/Bcl-2 ratio increased upon treatment. After administration of P. roxburghii and N. graveolens at a safe dose (1/10) of a lethal dose, the results showed improvement in both body weight gain and a significant decrease (p < 0.05) in tumor volume. Histopathological changes supported these improvements. Conclusively, the research outputs show that P. roxburghii and N. graveolens extracts can be utilized as potential chemopreventive agents for CRC treatment by stimulating cancer cell apoptosis and suppressing CRC survival and proliferation.

Can lymphovascular invasion be predicted by contrast-enhanced CT imaging features in patients with esophageal squamous cell carcinoma? A preliminary retrospective study. BMC Med Imaging 2022; 22:93. [PMID: 35581563 PMCID: PMC9116049 DOI: 10.1186/s12880-022-00804-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/07/2021] [Accepted: 04/20/2022] [Indexed: 11/10/2022] Open
Abstract
Background To investigate the value of contrast-enhanced CT (CECT)-derived imaging features in predicting lymphovascular invasion (LVI) status in esophageal squamous cell carcinoma (ESCC) patients. Methods One hundred and ninety-seven patients with postoperative pathologically confirmed esophageal squamous cell carcinoma treated in our hospital between January 2017 and January 2019 were enrolled in our study, including fifty-nine patients with LVI and one hundred and thirty-eight patients without LVI. The CECT-derived imaging features of all patients were analyzed. The CECT-derived imaging features were divided into quantitative features and qualitative features. The quantitative features consisted of the CT attenuation value of the tumor (CTVTumor), the CT attenuation value of the normal esophageal wall (CTVNormal), the CT attenuation value ratio of the tumor-to-normal esophageal wall (TNR), the CT attenuation value difference between the tumor and normal esophageal wall (ΔTN), the maximum thickness of the tumor measured by CECT (Thickness), the maximum length of the tumor measured by CECT (Length), and the gross tumor volume measured by CECT (GTV). The qualitative features consisted of an enhancement pattern, tumor margin, enlarged blood supply or drainage vessels to the tumor (EVFDT), and tumor necrosis. For the clinicopathological characteristics and CECT-derived imaging feature analysis, the chi-squared test was used for categorical variables, the Mann–Whitney U test was used for continuous variables with a nonnormal distribution, and the independent sample t-test was used for the continuous variables with a normal distribution. The trend test was used for ordinal variables. The association between LVI status and CECT-derived imaging features was analyzed by univariable logistic analysis, followed by multivariable logistic regression and receiver operating characteristic (ROC) curve analysis. Results The CTVTumor, TNR, ΔTN, Thickness, Length, and GTV in the group with LVI were higher than those in the group without LVI (P < 0.05). A higher proportion of patients with heterogeneous enhancement pattern, irregular tumor margin, EVFDT, and tumor necrosis were present in the group with LVI (P < 0.05). As revealed by the univariable logistic analysis, the CECT-derived imaging features, including CTVTumor, TNR, ΔTN and enhancement pattern, Thickness, Length, GTV, tumor margin, EVFDT, and tumor necrosis were associated with LVI status (P < 0.05). Only the TNR (OR 8.655; 95% CI 2.125–37.776), Thickness (OR 6.531; 95% CI 2.410–20.608), and tumor margin (OR 4.384; 95% CI 2.004–9.717) were independent risk factors for LVI in the multivariable logistic regression analysis. The ROC curve analysis incorporating the above three CECT-derived imaging features showed that the area under the curve obtained by the multivariable logistic regression model was 0.820 (95% CI 0.754–0.885). Conclusion The CECT-derived imaging features, including TNR, Thickness, tumor margin, and their combination, can be used as predictors of LVI status for patients with ESCC.

Abstract
BACKGROUND Neoadjuvant chemotherapy is often used prior to surgical resection for oesophageal adenocarcinoma but remains ineffective in a high proportion of patients. The histological Mandard tumour regression grade is used to determine chemoresponse but is not available at the time of treatment decision-making. The aim of this cohort study was to identify factors that predict chemotherapy response prior to surgery. METHODS A prospectively collected database of patients undergoing surgical resection for oesophageal adenocarcinoma from a high-volume UK institution was used. Patients were subcategorised using pathological tumour response into 'responders' (Mandard grade 1-3) and 'non-responders' (Mandard grade 4 and 5). Multivariable logistic regression analysis was performed to calculate crude and adjusted odds ratios (OR) with 95% confidence intervals (CI) for responder status adjusting for a variety of parameters. Receiver operating characteristic (ROC) curves were calculated. RESULTS Among 315 patients included, 102 (32%) were responders and 213 (68%) non-responders. A decrease in radiological tumour volume (OR 1.92 95%CI 1.02-3.62; p = 0.05), a 'partial response' RECIST score (OR 7.16 95%CI 1.49-34.36; p = 0.01), a clinically improved dysphagia score (OR 2.79 95%CI 1.05-7.04; p = 0.04) and lymphovascular invasion (OR 0.06 95%CI 0.02-0.13; p = 0.000) influenced responder status. ROC curve analysis for responder status utilising all available parameters had an area under the curve (AUC) of 0.86. CONCLUSION This study has highlighted the potential for using pre-defined factors to identify those patients who have responded to neoadjuvant chemotherapy, prior to surgical resection, potentially facilitating a more individualised therapeutic approach.

Tumor Stage-Based Gross Tumor Volume of Resectable Esophageal Squamous Cell Carcinoma Measured on CT: Association With Early Recurrence After Esophagectomy. Front Oncol 2021; 11:753797. [PMID: 34745986 PMCID: PMC8569516 DOI: 10.3389/fonc.2021.753797] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/05/2021] [Accepted: 10/04/2021] [Indexed: 01/18/2023] Open
Abstract
Objective To investigate relationship of tumor stage-based gross tumor volume (GTV) of esophageal squamous cell carcinoma (ESCC) measured on computed tomography (CT) with early recurrence (ER) after esophagectomy. Materials and Methods Two hundred and four consecutive patients with resectable ESCC including 159 patients enrolled in the training cohort (TC) and 45 patients in validation cohort (VC) underwent contrast-enhanced CT less than 2 weeks before esophagectomy. GTV was retrospectively measured by multiplying sums of all tumor areas by section thickness. For the TC, univariate and multivariate analyses were performed to determine factors associated with ER. Mann-Whitney U test was conducted to compare GTV in patients with and without ER. Receiver operating characteristic (ROC) analysis was performed to determine if tumor stage-based GTV could predict ER. For the VC, unweighted Cohen’s Kappa tests were used to evaluate the performances of the previous ROC predictive models. Results ER occurred in 63 of 159 patients (39.6%) in the TC. According to the univariate analysis, histologic differentiation, cT stage, cN stage, and GTV were associated with ER after esophagectomy (all P-values < 0.05). Multivariate analysis revealed that cT stage and GTV were independent risk factors with hazard ratios of 3.382 [95% confidence interval (CI): 1.533–7.459] and 1.222 (95% CI: 1.125–1.327), respectively (all P-values < 0.05). Mann-Whitney U tests showed that GTV could help differentiate between ESCC with and without ER in stages cT1-4a, cT2, and cT3 (all P-values < 0.001), and the ROC analysis demonstrated the corresponding cutoffs of 13.31, 17.22, and 17.83 cm3 with areas under the curve of more than 0.8, respectively. In the VC, the Kappa tests validated that the ROC predictive models had good performances for differentiating between ESCC with and without ER in stages cT1-4a, cT2, and cT3 with Cohen k of 0.696 (95% CI, 0.498–0.894), 0.733 (95% CI, 0.386–1.080), and 0.862 (95% CI, 0.603–1.121), respectively. Conclusion GTV and cT stage can be independent risk factors of ER in ESCC after esophagectomy, and tumor stage-based GTV measured on CT can help predict ER.

Abstract
Background To aid clinicians strategizing treatment for upper esophageal squamous cell carcinoma (ESCC), this retrospective study investigated associations between primary gross tumor volume (GTVp) and prognosis in patients given surgical resection, radiotherapy, or both resection and radiotherapy. Methods The population comprised 568 patients with upper ESCC given definitive treatment, including 238, 216, and 114 who underwent surgery, radiotherapy, or combined radiotherapy and surgery. GTVp as a continuous variable was entered into the multivariate Cox model using penalized splines (P-splines) to determine the optimal cutoff value. Propensity score matching (PSM) was used to adjust imbalanced characteristics among the treatment groups. Results P-spline regression revealed a dependence of patient outcomes on GTVp, with 30 cm3 being an optimal cut-off for differences in overall and progression-free survival (OS, PFS). GTVp ≥30 cm3 was a negative independent prognostic factor for OS and PFS. PSM analyses confirmed the prognostic value of GTVp. For GTVp < 30 cm3, no significant survival differences were observed among the 3 treatments. For GTVp ≥30 cm3, the worst 5-year OS rate was experienced by those given surgery. The 5-year PFS rate of patients given combined radiotherapy and surgery was significantly better than that of patients given radiotherapy. The surgical complications of patients given the combined treatment were comparable to those who received surgery, but radiation side effects were significantly lower. Conclusion GTVp is prognostic for OS and PFS in upper ESCC. For patients with GTVp ≥30 cm3, radiotherapy plus surgery was more effective than either treatment alone.

[PMID: 34370830 PMCID: PMC8405903 DOI: 10.1093/bjsopen/zrab069] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/09/2021] [Accepted: 06/17/2021] [Indexed: 12/31/2022] Open
Abstract
BACKGROUND Concern exists that patients born with oesophageal atresia (OA) may be at high risk for Barrett's oesophagus (BO), a known malignant precursor to the development of oesophageal adenocarcinoma. Screening endoscopy has a role in early BO identification but is not universal in this population. This study aimed to determine prevalence of BO after OA repair surgery, to quantify the magnitude of this association and inform the need for screening and surveillance. METHODS A systematic review, undertaken according to PRISMA guidelines, was preregistered on PROSPERO (CRD42017081001). PubMed and EMBASE were interrogated using a standardized search strategy on 31 July 2020. Included papers, published in English, reported either: one or more patients with either BO (gastric/intestinal metaplasia) or oesophageal cancer in patients born with OA; or long-term (greater than 2 years) follow-up after OA surgery with or without endoscopic screening or surveillance. RESULTS Some 134 studies were identified, including 19 case reports or series and 115 single- or multi-centre cohort studies. There were 13 cases of oesophageal cancer (9 squamous cell carcinoma, 4 adenocarcinoma) with a mean age at diagnosis of 40.5 (range 20-47) years. From 6282 patients under long-term follow-up, 317 patients with BO were reported. Overall prevalence of BO was 5.0 (95 per cent c.i. 4.5 to 5.6) per cent, with a mean age at detection of 13.8 years (range 8 months to 56 years). Prevalence of BO in series reporting endoscopic screening or surveillance was 12.8 (95 per cent c.i. 11.3 to 14.5) per cent. CONCLUSION Despite a limited number of cancers, the prevalence of BO in patients born with OA is relatively high. While limited by the quality of available evidence, this review suggests endoscopic screening and surveillance may be warranted, but uncertainties remain over the design and effectiveness of any putative programme.

Diagnostic Performance of Vascular Permeability and Texture Parameters for Evaluating the Response to Neoadjuvant Chemoradiotherapy in Patients With Esophageal Squamous Cell Carcinoma. Front Oncol 2021; 11:604480. [PMID: 34084740 PMCID: PMC8168434 DOI: 10.3389/fonc.2021.604480] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/09/2020] [Accepted: 04/21/2021] [Indexed: 12/09/2022] Open
Abstract
Background Esophageal squamous cell carcinoma (ESCC) is an aggressive type of cancer, associated with poor prognosis. The development of an accurate and non-invasive method to evaluate the pathologic response of patients with ESCC to chemoradiotherapy remains a critical issue. Therefore, the aim of this study was to assess the importance of vascular permeability and texture parameters in predicting the response to neoadjuvant chemoradiotherapy (NACRT) in patients with ESCC. Methods This prospective analysis included patients with T1–T2 stage of ESCC, without either lymphatic or metastasis, and distant metastasis. All patients underwent surgery having received two rounds of NACRT. All patients underwent dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) twice, i.e., before the first NACRT and after the second NACRT. Patients were assessed for treatment response at 30 days after the second NACRT. Patients were divided into the complete response (CR) and partial response (PR) groups based on their responses to NACRT. Vascular permeability and texture parameters were extracted from the DCE-MRI scans. After assessing the diagnostic performance of individual parameters, a combined model with vascular permeability and texture parameters was generated to predict the response to NACRT. Results In this study, the CR and PR groups included 16 patients each. The volume transfer constant (Ktrans), extracellular extravascular volume fraction (ve), and entropy values, as well as changes to each of these parameters, extracted from the second DCE-MRI scans, showed significant differences between the CR and PR groups. The area under the curve (AUC) of Ktrans, ve, and entropy values showed good diagnostic ability (0.813, 0.789, and 0.707, respectively). A logistic regression model combining Ktrans, ve, and entropy had significant diagnostic ability (AUC=0.977). Conclusions The use of a combined model with vascular permeability and texture parameters can improve post-NACRT prognostication in patients with ESCC.

Does a high Mandard score really define a poor response to chemotherapy in oesophageal adenocarcinoma? Br J Cancer 2021; 124:1653-1660. [PMID: 33742143 PMCID: PMC8110771 DOI: 10.1038/s41416-021-01290-4] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/20/2020] [Revised: 12/16/2020] [Accepted: 01/29/2021] [Indexed: 01/31/2023] Open
Abstract
BACKGROUND A high Mandard score implies a non-response to chemotherapy in oesophageal adenocarcinoma. However, some patients exhibit tumour volume reduction and a nodal response despite a high score. This study examines survival and recurrence patterns in these patients. METHODS Clinicopathological factors were analysed using multivariable Cox regression assessing time to death and recurrence. Computed tomography-estimated tumour volume change was examined in a subgroup of consecutive patients. RESULTS Five hundred and fifty-five patients were included. Median survival was 55 months (Mandard 1-3) and 21 months (Mandard 4 and 5). In the Mandard 4 and 5 group (332 patients), comparison between complete nodal responders and persistent nodal disease showed improved survival (90 vs 18 months), recurrence rates (locoregional 14.75 vs 28.74%, systemic 24.59 vs 48.42%) and circumferential resection margin positivity (22.95 vs 68.11%). Complete nodal response independently predicted improved survival (hazard ratio 0.34 (0.16-0.74). Post-chemotherapy tumour volume reduction was greater in patients with a complete nodal response (-16.3 vs -7.7 cm3, p = 0.033) with no significant difference between Mandard groups. CONCLUSION Patients with a complete nodal response to chemotherapy have significantly improved outcomes despite a poor Mandard score. High Mandard score does not correspond with a non-response to chemotherapy in all cases and patients with nodal downstaging may still benefit from adjuvant chemotherapy.

Abstract
The present study is to evaluate the significance in prognosis of relative tumor volume (RTV) in patients with non-resectable esophageal squamous cell carcinoma (ESCC) treated by definitive radiotherapy alone or in combination with chemotherapy.Fifty-eight consecutive patients with ESCC in UICC stage I to IV were retrospectively analyzed. Relative primary gross volume (RGTVp) was defined as primary gross volume (GTVp) divided by body volume. Relative primary gross volume for lymph nodes (RGTVnd) was defined as primary gross volume for lymph nodes (GTVnd) divided by body volume. The relationships were analyzed between overall survival (OS), disease free survival (DFS), local recurrence-free survival (LRFS), distant metastasis-free survival (DMFS), and RGTVp (RGTVnd) in univariate and multivariate analyses.The cut-off values of 0.947 and 0.007 were determined for RGTVp and RGTVnd, respectively. The 3-year OS, DFS, and LRFS for patients with RGTVp ≤ 0.947 vs RGTVp > 0.947 was 65.4% vs 25.0% (P = .001), 46.2% vs 12.5% (P = .002), and 90.1% vs 42.0% (P < .001). RGTVp was an independent risk factor for OS (P = .046), DFS (P = .015) and LRFS (P = .032), but showed no association with DMFS in univariate and multivariate analyses. The 3-year DFS and DMFS for patients with RGTVnd ≤ 0.007 vs RGTVnd > 0.007 was 44.4% vs 20.0% (P = .023), and 62.9% vs 24.6% (P < .004). RGTVnd was associated with DMFS (P = .012) in multivariate, but showed no associated with DFS.The present study demonstrates that RTV was an independent factor relevant to prognosis for ESCC. It provides new clinical basis for personalized therapeutic regimens and might be included in the staging system.

Abstract
BACKGROUND The tumor, node, metastasis classification system for staging esophageal cancer does not include tumor volume although it may be an important prognostic factor. We evaluated the prognostic value of tumor volume in esophageal cancer. METHODS We performed a retrospective study in patients with histologically confirmed primary esophageal cancer who underwent curative esophagectomy at our facility between April 1992 and December 2013. The Tumor Depth Parameter (TDP) was defined as mucosa = 1, submucosa = 2, muscularis propria = 3, adventitia = 4, and invasion into adjacent organs = 5. The pathological Tumor Volume Index (TVI) was defined as the major axis × the minor axis × TDP. The appropriate tumor diameter and TVI cutoff values were determined by the Youden index obtained from the receiver operating characteristic curve. Prognostic factors for overall survival were evaluated by univariate analysis and Cox proportional hazards regression models. RESULTS We enrolled 302 patients. In the univariate analysis, patient age and sex, thoracoscopic surgery, tumor depth of invasion and diameter, lymph node metastasis, and the TVI were significantly associated with overall survival. In our multivariate analysis, patient age and sex, thoracoscopic surgery, lymph node metastasis, and the TVI were independently associated with overall survival. CONCLUSIONS The pathological TVI was an independent prognostic factor in patients with esophageal carcinoma and could be included in the staging system of esophageal cancer.
