Abstract Background: To investigate the tumor volume, pre-treatment inflammatory biomarkers (pre-IBs), and their dynamic changes on early tumor response (ETR) in elderly patients (≥70 years) with esophageal squamous cell carcinoma (ESCC) underwent radiotherapy.Methods: The ETR was assessed according to RECIST 1.1 at 1 month after radiotherapy. The tumor volume ((gross tumor volume (GTV) at the initial treatment planning (GTVi), and GTV at shrinking irradiation field planning (GTVs)), IBs (neutrophil/lymphocyte (NLR), platelet/lymphocyte (PLR), and lymphocyte/monocyte (LMR)) which also included during treatment IBs (dur-IBs), and clinical variables were collected and analyzed from 197 patients received radiotherapy at our institution between 2015 and 2020. The tumor volume change rate (TVCR) and dynamic changes of IBs (delta-IBs) were defined as follows: TVCR=(1-GTVs/GTVi)×100%, delta-IBs=1-dur-IBs/pre-IBs. A nomogram based on logistic regression analysis were then established for predicting ETR.Results: GTVi and pre-LMR significantly decreased, pre-NLR, and pre-PLR significantly increased during radiotherapy or chemoradiotherapy (all P<0.001). Multivariate analysis indicated that TVCR [OR, 0.197; 95%CI, 0.093-0.414; P<0.001], pre-NLR [OR, 2.568; 95%CI, 1.031-6.394; P=0.043], and delta-NLR [OR, 2.831; 95%CI, 1.126-7.119; P=0.027] were statistically significant with ETR. And c-index of the nomogram established by combining all independent predictors for ETR was 0.769 [95%CI, 0.161–0.302].Conclusion: TVCR, Pre-NLR, and delta-NLR were significant with ETR in elderly patients with ESCC who underwent radiotherapy. And the developed nomogram with superior prediction ability for ETR could assist in patients counseling and guide to make individual treatments and follow-up strategies.

Abstract Background This retrospective study was to assess and compare the toxicity and efficacy of concurrent chemoradiotherapy (CCRT) with S-1 or docetaxel and cisplatin in patients with locally advanced esophageal squamous cell carcinoma (ESCC). Methods Patients with locally advanced ESCC who received CCRT with S-1 (70 mg/m2 twice daily on days 1–14, every 3 weeks for 2 cycles, S-1 group) or docetaxel (25 mg/m2) and cisplatin (25 mg/m2) on day 1 weekly (DP group) between 2014 and 2016 were retrospectively analyzed. Radiotherapy was delivered in 1.8–2.0 Gy per fraction to a total dose of 50–60 Gy. Treatment-related toxicities (Common Terminology Criteria for Adverse Events version 4.0), response rate, and survival outcomes were compared between groups. Results A total of 175 patients were included in this study (72 in the S-1 group and 103 in the DP group). Baseline characteristics were well balanced between the two groups. The incidence of grade 3–4 adverse events were significantly lower in the S-1 group than that of the DP group (22.2% vs. 45.6%, p = 0.002). In the DP group, elderly patients (> 60 years) had a significantly higher rate of grade 3–4 adverse events than younger patients (58.1% vs. 31.3%, p = 0.01). The objective overall response rate (complete response + partial response) was 68.1% in the S-1 group, and 73.8% the DP group (p = 0.497). The 3-year overall survival was 34.7% in the S-1 group, and 38.8% in the DP group (p = 0.422). The 3-year progression free survival in the DP group was higher than that in the S-1 group but without significant difference (33.0% vs. 25.0%, p = 0.275). Conclusion CCRT with S-1 is not inferior to CCRT with docetaxel and cisplatin and is better tolerated in in elderly patients with locally advanced ESCC.

PurposeTo evaluate the time course of therapy-induced changes in tumor glucose use during chemoradiotherapy of esophageal squamous cell carcinoma (ESCC) and to correlate the reduction of metabolic activity with histopathologic tumor response and patient survival.Patients and MethodsThirty-eight patients with histologically proven intrathoracic ESCC (cT3, cN0/+, cM0) scheduled to undergo a 4-week course of preoperative simultaneous chemoradiotherapy followed by esophagectomy were included. Patients underwent positron emission tomography with the glucose analog fluorodeoxyglucose (FDG-PET) before therapy (n = 38), after 2 weeks of initiation of therapy (n = 27), and preoperatively (3 to 4 weeks after chemoradiotherapy; n = 38). Tumor metabolic activity was quantitatively assessed by standardized uptake values (SUVs).ResultsMean tumor FDG uptake before therapy was 9.3 ± 2.8 SUV and decreased to 5.7 ± 1.9 SUV 14 days after initiation of chemoradiotherapy (−38% ± 18%; P < .0001). The preoperative scan showed an additional decrease of metabolic activity to 3.3 ± 1.1 SUV (P < .0001). In histopathologic responders (< 10% viable cells in the resected specimen), the decrease in SUV from baseline to day 14 was 44% ± 15%, whereas it was only 21% ± 14% in nonresponders (P = .0055). Metabolic changes at this time point were also correlated with patient survival (P = .011). In the preoperative scan, tumor metabolic activity had decreased by 70% ± 11% in histopathologic responders and 51% ± 21% in histopathologic nonresponders.ConclusionChanges in tumor metabolic activity after 14 days of preoperative chemoradiotherapy are significantly correlated with tumor response and patient survival. This suggests that FDG-PET might be used to identify nonresponders early during neoadjuvant chemoradiotherapy, allowing for early modifications of the treatment protocol.

The aim of this study was to compare the perioperative outcomes and long-term survival rates of the McKeown and Sweet procedures in patients with esophageal cancer younger than 70 years or older than 70 years. A total of 1432 consecutive patients with esophageal squamous cell carcinoma (ESCC) who received surgery at Sun Yat-sen University Cancer Center from January 2009 to October 2012 were analyzed. Propensity score matching was used to balance the clinical characteristics of the patients who underwent different surgical approaches, and 275 and 71 paired cases were matched among those younger and older than 70 years, respectively. The prognosis and postoperative outcomes were compared between the McKeown and the Sweet esophagectomy. For patients younger than 70 years, those who underwent the McKeown procedure had better overall survival (OS) than those in the Sweet group (log rank = 4.467; P = .035). However, no significant difference in disease-free survival and OS was observed between two approaches for the elderly patients (log rank = 1.562; P = .211 and log rank = 0.668; P = .414, respectively). Cox regression analysis revealed that McKeown approach was a positive prognostic factor compared to the Sweet approach for patients younger than 70 years in univariable analysis (HR = 0.790; 95% CI, 0.625-0.997; P = .047), whereas the surgical approach was not significantly related to the prognosis in the elderly patients. For patients older than 70 years, the occurrence of anastomotic fistula increased in those who underwent the McKeown procedure (23.9% vs 11.3%, P = .038, for the McKeown and Sweet esophagectomy, respectively). The McKeown approach increases the OS in younger patients with ESCC. However, for patients older than 70 years, the Sweet approach was proven to be an effective therapy, given the better perioperative outcomes and similar long-term survival compared with patients in the McKeown group.

ObjectivesTo investigate the tumor volume and its change on short-term outcome in esophageal squamous cell carcinoma (ESCC) patients who underwent definitive radiotherapy or chemoradiotherapy.Methods and MaterialsAll data were retrospectively collected from 418 ESCC patients who received radiotherapy or chemoradiotherapy at our institution between 2015 and 2019. Short-term outcome using the treatment response evaluation was assessed according to the RECIST 1.1. The tumor volume change rate (TVCR) was defined as follows: TVCR = {1 − [gross tumor volume (GTV) at shrinking irradiation field planning)]/(GTV at the initial treatment planning)} ×100%. Chi square test was used to compare the clinic characteristics in different TVCR groups, and the difference between initial GTV (GTVi) and shrinking GTV (GTVs) was compared using Wilcoxon’s sign rank test. Logistic regression analysis and Spearman correlation was performed.ResultsThere was a significant decrease in GTVi compared to GTVs (P &lt; 0.001). In univariate analysis, age, cT-stage, TNM stage, treatment modality, GTVi, and TVCR were associated with short-term outcome (all P&lt; 0.05). In multivariate analysis, gender and TVCR were statistically significant (P = 0.010, &lt;0.001) with short-term outcome, and the combined predictive value of gender and TVCR exceeded that of TVCR (AUC, 0.876 vs 0.855).ConclusionsTVCR could serve to forecast short-term outcome of radiotherapy or chemoradiotherapy in ESCC. It was of great significance to guide the individualized treatment of ESCC.
