Abstract
Purpose: To analyze the outcome and prognosis of patients with
refractory cervical lymph node metastasis of thoracic esophageal squamous cell
carcinoma after external irradiation, who underwent interstitial 125I
brachytherapy as a salvage treatment with a CT-guided coplanar template-assisted
technique. We also want to compare the dosimetry of 3D printed coplanar
template-assisted interstitial 125I brachytherapy preoperative and
postoperative, and to explore the accuracy of this technology. Material
and methods: We retrospectively collected and analyzed the results of
32 patients with refractory cervical lymph node metastasis of thoracic
esophageal squamous cell carcinoma after external irradiation, who underwent
interstitial 125I brachytherapy as a salvage treatment with a
CT-guided coplanar template-assisted technique from January 2012 to December
2017. Results: The actual D90 were 114 to 240 Gy, and the median
postoperative dosimetry assessment was 177.5 Gy. The local control rates at 3,
6, 9, and 12 months were 87.5%, 59.38%, 40.63%, and 31.25%, respectively. The
median local control time was 7.5 months. The median overall survival time was
10.5 months (95% CI, 8.9-13.4), and the survival rates of 1- and 2-year,
respectively, were 43.75% and 9.38%. There were 36 lesions in 32 patients. By
performing a paired t-test analysis, there was no significant
difference in D90, D100, V100, V150, V200, GTV volume, CI, EI, and HI between
preoperative and postoperative (P > .05).
Conclusions: Interstitial 125I brachytherapy can be
used as a salvage treatment for patients with refractory cervical lymph node
metastasis of thoracic esophageal squamous cell carcinoma after external
irradiation. With the auxiliary function of 3D printed coplanar template, the
main dosimetry parameters verified after the operation can meet the requirements
of the preoperative plan with good treatment accuracy.

Abstract
AIM This study aimed to clarify the prognostic factors, the advantageous factors of R0 curative resection, and optimal extents of lymph node dissection for conversion esophagectomy after induction therapy. METHODS Among 1903 patients with esophageal cancer at Toranomon Hospital between January 2006 to May 2020, 151 patients with locally advanced T4b thoracic esophageal cancer were divided into two groups according to treatment: conversion surgery group (n = 54) and non-surgical treatment group (n = 97) for comparison. RESULTS The patients who underwent R0 curative resection showed preferable survival comparable to the survival rate of patients with cCR in the non-surgical treatment group (1-, 3- and 5-year survival: 96.9%, 82.1% and 76.7% vs 94.1%, 86.3%, and 86.3%; P = 0.770). Multivariate analysis revealed that the T4b tumor invasion by primary site (odds ratio (OR) = 6.100; 95% CI, 1.439-25.865: P = 0.014) and time to conversion surgery from start of induction therapy within four months (OR = 5.229; 95% CI, 1.296-21.102: P = 0.020) were all independent advantageous factors of R0 curative resection. Actuarial 1-, 3- and 5-year survival rates in patients who underwent conversion surgery with D2-3 lymphadenectomy were 90.9%, 48.6%, and 40.8%, respectively. CONCLUSIONS R0 resection led to improved prognosis in conversion esophagectomy for cT4b esophageal cancer. The T4b tumor invasion by primary site and time to conversion surgery from start of induction therapy within 4 months were independent advantageous factors of R0 curative resection. In addition, standard radical esophagectomy including prophylactic D2-/3- lymphadenectomy should be performed if it is possible, while taking adequate care regarding the increased risk after induction therapy.

Abstract
Background Clinically, many esophageal cancer patients who planned for radiation therapy have already undergone diagnostic Positron-emission tomography/computed tomography (PET/CT) imaging, but it remains unclear whether these imaging results can be used to delineate the gross target volume (GTV) of the primary tumor for thoracic esophageal cancer (EC). Methods Seventy-two patients diagnosed with thoracic EC had undergone prior PET/CT for diagnosis and three-dimensional CT (3DCT) for simulation. The GTV3D was contoured on the 3DCT image without referencing the PET/CT image. The GTVPET-ref was contoured on the 3DCT image referencing the PET/CT image. The GTVPET-reg was contoured on the deformed registration image derived from 3DCT and PET/CT. Differences in the position, volume, length, conformity index (CI), and degree of inclusion (DI) among the target volumes were determined. Results The centroid distance in the three directions between two different GTVs showed no significant difference (P > 0.05). No significant difference was found among the groups in the tumor volume (P > 0.05). The median DI values of the GTVPET-reg and GTVPET-ref in the GTV3D were 0.82 and 0.86, respectively (P = 0.006). The median CI values of the GTV3D in the GTVPET-reg and GTVPET-ref were 0.68 and 0.72, respectively (P = 0.006). Conclusions PET/CT can be used to optimize the definition of the target volume in EC. However, no significant difference was found between the GTVs delineated based on visual referencing or deformable registration whether using the volume or position. So, in the absence of planning PET–CT images, it is also feasible to delineate the GTV of primary thoracic EC with reference to the diagnostic PET–CT image.

Abstract
In spite of repeated appeal of the effectiveness of three-field lymphadenectomy (3FL) by Japanese esophageal surgeons, it has not been accepted worldwide as a standard therapeutic measure for thoracic esophageal cancer. In this review, a concise summary of the history of 3FL, its present position, and its future perspective is discussed. Although a lack of randomized controlled trial (RCT) is one of the largest criticisms of 3FL, it seems difficult to make 3FL world-standard even if a RCT with a positive result was made. The essence of 3FL has revealed the fact that bilateral cervical paraesophageal nodes and nodes in the bilateral supraclavicular fossae are regional nodes of thoracic esophageal cancer. To let the world admit this essence should be the real endpoint of "3FL issue" without RCT. In the era of new modalities, Japanese surgeons should be free from the idea that 3FL is indispensable though the essence of 3FL should remain.

Abstract
Background: The standard treatment for esophageal carcinoma is extensive resection of the tumor and esophagogastric anastomosis despite the high incidence of related anastomotic complications, such as stricture and leakage. Thus, the choice of the cervical esophagogastric anastomotic method-triangulating stapling (TS) versus circular stapling (CS)-is a critical decision for the surgeon. Aim: To compare the incidence of major adverse outcomes between TS and CS in patients with resectable thoracic esophageal cancer. Methods: For this meta-analysis, PubMed, Embase, Wiley Online Library, Google Scholar, Wanfang, and China National Knowledge Infrastructure databases were searched for subject-relevant studies by using a rigorous study protocol established according to the recommendations of the Cochrane Handbook. Anastomotic leakage, anastomotic stricture, and postoperative pulmonary complications were the primary endpoints used for comparison. Relative risk (RR) with 95% confidence intervals (CI) were calculated to assess the strength of association. Results: Six studies were selected by our inclusion/exclusion criteria and represented a total of 739 patients in our meta-analysis of TS (n = 376) versus CS (n = 363). The TS group showed a lower incidence of anastomotic stricture (RR: 0.23 [95% CI: 0.08-0.63]; P = .004) and pulmonary complications (RR: 0.57 [95% CI: 0.37-0.87]; P = .01). However, the incidence of anastomotic leakage was similar for the two groups (RR: 0.66 [95% CI: 0.41-1.09]; P = .1). Subgroup analysis of four studies in which the surgical methods were minimally invasive demonstrated the TS group to have a lower incidence of lung complications (RR: 0.55 [95% CI: 0.35-0.87]; P = .01), anastomotic leakage (RR: 0.36 [95% CI: 0.18-0.74]; P = .005), and anastomotic stricture (RR: 0.23 [95% CI: 0.05-0.98]; P = .05). Conclusion: The TS method for cervical esophagogastric anastomosis after esophagectomy had a lower incidence of anastomotic stricture and postoperative lung complications.

Abstract
Background: To date, intensity-modulated radiation therapy (IMRT) with concurrent chemoradiotherapy (CCRT) and CCRT with standard fractionation three-dimensional conformal radiation therapy (3D-CRT) have not been compared. In this study, the outcomes of IMRT-based concurrent CCRT and those of 3D-CRT-based CCRT were compared in patients with thoracic esophageal squamous cell carcinoma (TESCC). Methods: We enrolled 2062 patients with TESCC who had received CCRT and categorized them into two groups on the basis of their treatment modality: Group 1 (3D-CRT-based CCRT) and Group 2 (IMRT-based CCRT). Results: Multivariate Cox regression analysis indicated that the American Joint Committee on Cancer advanced stages (≥IIIA) and 3D-CRT were significant independent predictors of poor outcomes in patients with TESCC who received definitive CCRT. Moreover, receiving IMRT-based CCRT (adjusted hazard ratio [aHR]: 0.88, 95% confidence interval [CI]: 0.78–0.98) was a significant independent prognostic factor for overall survival (p = 0.0223). In Group 2, aHRs (95% CIs) for overall mortality at early (IA–IIB) and advanced clinical stages were 0.91 (0.67–1.25, p = 0.5746) and 0.88 (0.77–0.99, p = 0.0368), respectively. Conclusion: IMRT-based CCRT resulted in higher survival rates in patients with advanced clinical stages of TESCC (i.e., IIIA–IIIC), namely, clinical T3, clinical T4, or lymph node involvement.

Abstract
Controversy about the adequate extent of lymph node (LN) dissection persists in surgery for thoracic esophageal squamous cell carcinoma (ESCC). The present study estimates the feasibility and strategy of common hepatic artery LN dissection during ESCC surgery.The clinical data of 482 patients with ESCC, who underwent thoracolaparoscopic esophagectomy at Fujian Medical University Union Hospital, were retrospectively selected. Among the 482 ESCC patients, 224 patients underwent thoracolaparoscopic esophagectomy with routine common hepatic artery LN dissection (cohort 1), while 258 patients underwent the same procedure without common hepatic artery LN dissection (cohort 2). The proposed operation method was introduced to safely dissect the common hepatic artery LN. Both univariate and multivariate analyses were performed to analyze the clinicopathological factors correlated to the common hepatic artery LN metastasis.The main postoperative complications were pneumonia, anastomotic leakage, vocal cord palsy and cardiovascular disease. There was no significant difference in the incidence of major postoperative complications between the 2 cohorts (P >.05), and the incidence was similar in a number of reports. The metastatic rate of common hepatic artery LNs was 4.91%, which was relatively lower. Based on the logistic regression analysis of 5 factors, tumor location and T classification were risk factors for common hepatic artery LN metastasis (P <.05).Routine common hepatic artery LN dissection is safe and feasible during a thoracolaparoscopic esophagectomy for ESCC. Although the metastatic rate is lower, common hepatic artery LN dissection should be performed for lower thoracic ESCCs, especially for tumors that invade the outer membrane.

Abstract
BACKGROUND Few large, prospective, randomized studies have investigated the value and optimal application of neoadjuvant chemoradiotherapy followed by surgery (trimodality therapy) or definitive concurrent chemoradiotherapy (CCRT) for patients with thoracic esophageal squamous cell carcinoma (TESCC). METHODS The authors analyzed data from patients with TESCC in the Taiwan Cancer Registry database. To compare their outcomes, patients with TESCC were enrolled and categorized into the following groups according to treatment modality: group 1, those who underwent surgery alone; group 2, those who received trimodality therapy; and group 3, those who received definitive CCRT. Group 1 was used as the control arm for investigating the risk of mortality after treatment. RESULTS In total, 3522 patients who had TESCC without distant metastasis were enrolled. Multivariate Cox regression analysis indicated that a Charlson comorbidity index score ≥3, American Joint Committee on Cancer stage ≥IIA, earlier year of diagnosis, alcohol consumption, cigarette smoking, and definitive CCRT were significant, independent predictors of a poor prognosis. After adjustment for confounders, adjusted hazard ratios and 95% confidence intervals (CIs) for overall mortality in patients with clinical stage I, IIA, IIB, IIIA, IIIB, and IIIC TESCC were 2.01 (95% CI, 0.44-6.18), 1.65 (95% CI, 0.99-2.70), 1.48 (95% CI, 0.91-2.42), 0.66 (95% CI, 1.08-1.14), 0.39 (95% CI, 0.26-0.57), and 0.44 (95% CI, 0.24-0.83), respectively, in group 2; and 2.06 (95% CI, 1.18-3.59), 2.65 (95% CI, 1.76-4.00), 2.25 (95% CI, 1.49-3.39), 1.34 (95% CI, 0.79-2.28), 0.82 (95% CI, 0.57-1.17), and 0.93 (95% CI, 0.51-1.71), respectively, in group 3. CONCLUSIONS Trimodality therapy may be beneficial for the survival of patients with advanced-stage (IIIA-IIIC) TESCC, and CCRT might be an alternative to surgery alone in these patients.

Abstract
BACKGROUND Few large, prospective, randomized studies have investigated the effectiveness of esophagectomy in patients with thoracic esophageal squamous cell carcinoma (TESCC) who receive definitive radiotherapy (RT) or concurrent chemoradiotherapy (CCRT) through modern, intensity modulated-RT (IMRT) techniques. The therapeutic effects of esophagectomy in patients with TESCC were evaluated using modern clinical staging and RT techniques and suitable RT doses. METHODS The authors analyzed data from patients with TESCC from the Taiwan Cancer Registry database. Patients were categorized into the following groups on the basis of treatment modality to compare their outcomes: group 1 received definitive CCRT, group 2 received neoadjuvant RT followed by esophagectomy (total IMRT dose, ≥50 grays [Gy]), and group 3 receiving neoadjuvant CCRT followed by esophagectomy (total IMRT dose, ≥ 50 Gy). The median total RT dose and fraction size were 50.4 Gy and 1.8 Gy per fraction, respectively. Group 1 was used as the control arm for investigating the risk of mortality after treatment. RESULTS In total, 3123 patients who had TESCC without distant metastasis were enrolled. Patient ages 65 years and older, Charlson comorbidity index scores ≥3, advanced clinical stages (IIA-IIIC), alcohol consumption, and cigarette smoking were identified as significant, independent poor prognostic risk factors for overall survival in multivariate Cox regression analyses. In group 3, after adjustment for confounders, the adjusted hazard ratios (95% confidence intervals [CIs]) for overall mortality were 0.62 (95% CI, 0.41-0.93) for patients with clinical stage IIA disease, 0.61 (95% CI, 0.41-0.91) for those with clinical stage IIB disease, 0.47 (95% CI, 0.38-0.55) for those with clinical stage IIIA disease, 0.47 (95% CI, 0.39-0.56) for those with clinical stage IIIB disease, and 0.46 (95% CI, 0.37-0.57) for those with clinical stage IIIC disease. CONCLUSIONS Esophagectomy can be beneficial in patients with TESCC after definitive CCRT, especially in those who have advanced-stage disease.

Abstract
The objective of the study was to compare geometrical differences of target volumes based on four-dimensional computed tomography (4DCT) maximum intensity projection (MIP) and 18F-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT) images of primary thoracic esophageal cancer for radiation treatment. Twenty-one patients with thoracic esophageal cancer sequentially underwent contrast-enhanced three-dimensional computed tomography (3DCT), 4DCT, and 18F-FDG PET/CT thoracic simulation scans during normal free breathing. The internal gross target volume defined as IGTVMIP was obtained by contouring on MIP images. The gross target volumes based on PET/CT images (GTVPET ) were determined with nine different standardized uptake value (SUV) thresholds and manual contouring: SUV≥2.0, 2.5, 3.0, 3.5 (SUVn); ≥20%, 25%, 30%, 35%, 40% of the maximum (percentages of SUVmax, SUVn%). The differences in volume ratio (VR), conformity index (CI), and degree of inclusion (DI) between IGTVMIP and GTVPET were investigated. The mean centroid distance between GTVPET and IGTVMIP ranged from 4.98 mm to 6.53 mm. The VR ranged from 0.37 to 1.34, being significantly (P<0.05) closest to 1 at SUV2.5 (0.94), SUV20% (1.07), or manual contouring (1.10). The mean CI ranged from 0.34 to 0.58, being significantly closest to 1 (P<0.05) at SUV2.0 (0.55), SUV2.5 (0.56), SUV20% (0.56), SUV25% (0.53), or manual contouring (0.58). The mean DI of GTVPET in IGTVMIP ranged from 0.61 to 0.91, and the mean DI of IGTVMIP in GTVPET ranged from 0.34 to 0.86. The SUV threshold setting of SUV2.5, SUV20% or manual contouring yields the best tumor VR and CI with internal-gross target volume contoured on MIP of 4DCT dataset, but 3DPET/CT and 4DCT MIP could not replace each other for motion encompassing target volume delineation for radiation treatment.
