Abstract
BACKGROUND Definitive concurrent chemoradiotherapy (dCCRT) is suggested as the standard treatment for cervical esophageal squamous cell carcinoma (CESCC). This retrospective propensity study compared the 8-year survival outcomes and acute treatment toxicities of these patients treated with elective nodal irradiation (ENI) versus involved-field irradiation (IFI). MATERIALS AND METHODS Patients with stage II-IV CESCC treated with dCCRT at the Fourth Hospital of Hebei Medical University between January 1, 2007 and December 31, 2020 were enrolled in the study. All the patients were restaged according to the American Joint Commission 8th edition criteria. The propensity score matching (PSM) was used to minimize the effects of treatment selection bias and potential confounding factors including sex, age, ECOG score, clinical T stage, clinical N stage, clinical TNM stage and radiation dose between the ENI group and IFI group. Survival and the prognostic factors were evaluated. RESULTS The 131 eligible patients underwent ENI (60 patients, 45.8%) or IFI (71 patients, 54.2%). The median follow-up time was 91.1 months (range, 23.8-182.0 months) for all the patients. The median OS, 1-, 3-, 5-, and 8-year OS rates were 44.4 months, 87.8%, 55.1%, 38.3%, and 27.2%, respectively. After PSM, there were 49 patients in each group. The median OS, 1-, 3-, 5-, and 8-year OS rates for ENI and IFI group were 32.0 months, 83.7%, 48.5%, 38.5% and 31.1% versus 45.2 months, 89.8%, 52.5%, 37.5%, 26.1%, respectively (P = 0.966; HR 0.99, 95% CI 0.61-1.61). Similar locoregional control was obtained in both groups. The tendency of leukocytopenia and neutropenia was higher in ENI than in IFI (59.2% vs. 38.8%; P = 0.068 and 30.6% vs. 14.3%; P = 0.089) at the end of dCCRT. CONCLUSION Cervical esophageal squamous cell carcinoma patients undergoing definitive concurrent chemoradiotherapy has a satisfactory prognosis with organ conservation. The involved-field irradiation might be a better alternative owing to similar overall survival outcomes and local control with less toxicity of myelosuppression.

Abstract
Purpose This trial aims to explore the efficacy and safety of involved-field irradiation (IFI) combined with paclitaxel plus cisplatin as concurrent chemoradiotherapy for locally advanced esophageal squamous cell carcinoma (ESCC), under the premise of intensity-modulated radiotherapy (IMRT). Methods Enrolled patients with locally advanced ESCC were treated with definitive concurrent chemoradiotherapy. IFI was administered adopting IMRT and the total dose was 61.2 Gy delivered in 34 fractions. On the first day of radiotherapy, the patients were treated with paclitaxel and cisplatin one cycle per month for 2 cycles followed by the same regimen in consolidation chemotherapy for two cycles. The primary endpoint of the study was the 2-year locoregional recurrence-free survival (LRFS) rate, and secondary endpoints included overall survival (OS), progression-free survival (PFS), and safety. Results Between January 2018 and September 2020, 108 patients participated in the trial. 78.7% (85/108) of patients completed all 4 cycles of chemotherapy. The median follow-up of the surviving patients was 33.9 months (interquartile range, 29.2–41.1). The 2-year LRFS rate, as the primary endpoint, was 64.2%. In addition, the median PFS was 39.2 months, and 1-year and 3-year OS rates of 88.0% and 63.3%, respectively. Among the patients, out-of-field regional failure was seen in only 7 (6.5%) patients. Neutropenia grade 3 and 4 occurred in 21.3% and 37.0% of the patients, respectively. Conclusions IFI using IMRT combined with paclitaxel and cisplatin concurrent chemotherapy for locally advanced ESCC yields encouraging local control and overall survival, but high hematological toxicity.

Abstract
Objective: To explore the therapeutic efficacy and safety of elective nodal irradiation (ENI) and involved field irradiation (IFI) in intensity-modulated radiotherapy for esophageal cancer, screen the patients suitable to undergo ENI radiotherapy and provide evidences for individual treatment of esophageal cancer. Methods: A retrospective analysis was performed on the clinical data of 924 patients with esophageal cancer who received definitive intensity-modulated radiotherapy in our hospital from January 2006 to December 2015. Among them, 272 patients received ENI and the other 652 patients received IFI. The clinicopathologic characteristics of 272 cases in ENI group and 652 cases in IFI group, who were recruited according to the balance of propensity score matching method, were compared. The Kaplan-Meier method was used to calculate 1-year, 3-years and 5-years local-regional failure-free survival (LRFFS), progression-free survival (PFS) and overall survival (OS) rates. The univariate and multivariate analysis of prognostic factors were also determined by Cox proportional hazard model and Long-rank test. Results: The clinicopathologic characteristics of these two group were not significantly different (P>0.05). The median follow-up time was 85.9 months and the follow-up rate was 95.9%. The 1-year, 3-years, 5-years PFS rates of the ENI groups were 65.3%, 31.7%, 18.4%, respectively, higher than 54.0%, 20.9%, 12.7% of the IFI group (P=0.001). The 1-year, 3-years, 5-years OS rates of the ENI groups were 79.0%, 43.7%, 24.9%, respectively, higher than 75.0%, 31.8%, 17.2% of the IFI group (P=0.003). In multivariate analysis, the sex, tumor volume, N stage and radiation field were independent factors for PFS and OS (P<0.05). Subgroup analysis showed that patients with male, age≤66 year, cervical and upper-thoracic location, tumor length≤6 cm, T1-2 stage, N0-1 stage, Ⅰ-Ⅱ stage, tumor volume≤50 cm(3), dosage>60 Gy and≤2 cycles of chemotherapy in the ENI group had a better survival rate than those in the IFI group (P<0.05). The total failure rate, local-regional failure rate in ENI group were significantly lower than those of IFI group (P=0.001, P=0.004). The incidence of bone marrow depression≥ grade 2 and 3 in ENI group was higher than that of the IFI group (P<0.05). However, the incidences of radioactive esophagitis≥ grade 3, radioactive pneumonia and late adverse reactions were not significantly different between these two groups (P>0.05). Conclusion: Compared with IFI, ENI can significantly improve the long-term survival for young, early TN stage and cervical/upper-thoracic esophageal cancer patients underwent chemotherapy.

Abstract
Background To assess the comparative efficacy and safety of elective nodal irradiation (ENI) and involved-field irradiation (IFI) in patients with esophageal cancer (EC) receiving neoadjuvant chemoradiotherapy plus surgery (nCRTS). Material and methods PubMed, Embase, Cochrane Library, Web of Science and major meetings were searched for randomized controlled trials (RCTs) that compared at least two of the following treatment regimens: nCRTS, neoadjuvant chemotherapy plus surgery (nCTS), and surgery (S) alone. Overall survival (OS) was the primary outcomes of interest, reported as hazard ratio (HR) and 95% confidence intervals (CIs). A Bayesian network meta-analysis was performed to compare all regimens simultaneously. Results Twenty-nine RCTs with a total of 5212 patients were included in the meta-analysis. Both nCRTS adopting ENI (nCRTS-ENI) (HR = 0.63, 95% CI: 0.48–0.83) and nCRTS adopting IFI (nCRTS-IFI) (HR = 0.75, 95% CI: 0.66–0.86) significantly improved OS compared to S alone. No significant differences in OS, locoregional recurrence, distant metastases, R0 resection and postoperative mortality were observed between nCRTS-ENI and nCRTS-IFI. In subgroup analyses, nCRTS-IFI showed a significant OS advantage over nCTS (HR = 0.78, 95% CI: 0.63–0.96) and S alone (HR = 0.50, 95% CI: 0.38–0.68) for esophagus squamous cell carcinoma (ESCC), but nCRTS-ENI did not; nCRTS-ENI using three-dimensional radiotherapy (3D-RT) resulted in an improved OS compared to that with 2D-RT (HR = 0.58, 95% CI: 0.34–0.99). Based on treatment ranking in term of OS, nCRTS-IFI (0.90) and nCRTS-ENI (0.96) was ranked the most effective treatment for ESCC and esophagus adenocarcinoma (EAC), respectively. Conclusion Either adopting ENI or IFI, nCRTS is likely to be the optimal treatment for resectable EC, and nCRTS-IFI and nCRTS-ENI seem to be more effective for patients with ESCC and EAC, respectively. Future head to head comparison trials are needed to confirm these findings.

Abstract
Definitive radiotherapy has an affirmative role in treating non-operable esophageal cancer; however, the controversy between elective lymph node irradiation (ENI) and involved-field irradiation (IFI) still remains. To ascertain the benefits and disadvantages of the two radiation target volumes, we performed a meta-analysis with 7 related publications. According to our findings, patients treated with ENI and IFI had nearly identical 1, 2, and 3-year survival rates (pooled odds ratio [OR] = 1.004, p = 0.980, and pooled OR = 1.15, p = 0.594, and pooled OR = 0.918, p = 0.679, respectively). Likewise, no significant differences were detected in local recurrence rates (pooled OR = 1.04, p = 0.883), regional recurrence rates (pooled OR = 0.65, p = 0.555), and distant metastasis rates (pooled OR = 1.29, p = 0.309) between the two treatment groups. However, IFI could significantly decrease the incidences of acute radiation esophagitis (pooled OR = 2.30, p = 0.001) and late pneumonia (pooled OR = 2.52, p = 0.04) compared with ENI. This meta-analysis provides evidence that IFI is more feasible for non-operable esophageal cancer than ENI.

Abstract
BACKGROUND For patients with postoperative lymph node (LN) recurrent esophageal cancer, the appropriate irradiation field in chemoradiotherapy (CRT) remains controversial. We assessed the clinical outcomes and prognostic factors related to involved-field CRT for postoperative solitary LN recurrence of esophageal squamous cell carcinoma (ESCC). METHODS We retrospectively evaluated 21 patients who had received curative resection, with LN recurrence of ESCC. Patients received CRT using 5-fluorouracil plus cisplatin or docetaxel, prescribed at 60 Gy in 30 fractions. We evaluated the pattern of failure, toxicities, survivals, and prognostic factors. We defined elective nodal failure (ENF) as recurrence in a regional LN without involved-field failure. RESULTS The median follow-up duration was 32 months (range, 4-106 months). Nine patients experienced failure-4 (19%) within involved-field and 5 (24%) with distant metastasis. No patients had ENF. We observed no severe toxicities. The 2-year overall survival (OS) rate was 78%. In the univariate analysis of OS, two factors, the maximal diameter of the metastatic LN < 25 mm and the absence of serum p53 antibodies (s-p53-Abs), were associated with a significantly better prognosis (p = 0.025 and p = 0.01, respectively). CONCLUSIONS Involved-field CRT for postoperative solitary LN recurrence of ESCC did not cause ENF and was without severe toxicities. Two factors, a length of the metastatic LN < 25 mm and the absence of s-p53-Abs may improve the treatment outcome. Involved-field CRT is a treatment option worthy of consideration for postoperative solitary LN recurrence of ESCC.

Abstract
PURPOSE To compare the prognosis of elderly patients with early oesophageal carcinoma between radical elective nodal prophylactic irradiation and involved-field irradiation and to estimate the failure modes and adverse effects, then to provide the patients the safe and individual therapeutic regimens. MATERIAL AND METHODS The charts of 96 patients aged 65 and over with early stage oesophageal carcinoma receiving radical radiotherapy in our department were retrospectively analysed. Of all the patients, 49 received elective nodal prophylactic irradiation and the other 47 received involved-field irradiation. After completion of the whole treatment, we analysed short-term effects, tumour local control, overall survival of the patients, failure modes and adverse effects. RESULTS The 1-, 3-, and 5-year local control rate in elective nodal irradiation and involved-field irradiation groups were 80.6%, 57.4%, 54.0% and 65.4%, 46.5%, 30.5% respectively, and the difference was statistically significant (χ2=4.478, P=0.03). The differences of overall survival and progression-free survival were not significant (P>0.05). The difference of 1-, 3-, and 5-years local regional failure rate was statistically significant between elective nodal prophylactic irradiation and involved-field irradiation groups, except for the overall failure and distant metastasis rates. The overall incidence of radiation-induced oesophagitis after elective nodal irradiation or involved-field irradiation was 79.6% and 59.6%, and the difference was statistically significant (χ2=4.559, P=0.03). The difference of radiation pneumonitis between elective nodal prophylactic irradiation and involved-field irradiation was not significant (12.2% vs 14.9%; χ2=0.144, P=0.7). CONCLUSION For elderly patients with early stage oesophageal carcinoma receiving radical radiotherapy, although elective nodal prophylactic irradiation could increase the incidence of radiation-induced oesophagitis, patients could tolerate the treatment and benefit from local control.
