Abstract
PURPOSE Local primary-recurrence of esophageal squamous cell carcinoma (ESCC) after definitive treatment has the potential for increasing overall survival with re-irradiation (Re-RT), especially with advanced technique. This study aimed to evaluate the efficacy and toxicities of Re-RT using intensity-modulated radiotherapy (IMRT)/volumetric modulated arc therapy (VMAT) for local primary-recurrence of ESCC. MATERIALS AND METHODS A total of 130 ESCC patients with local primary-recurrence from Xijing hospital between 2008 and 2021 were enrolled and 30 patients underwent IMRT/VMAT based salvage Re-RT. Cox regression analysis was used to analyze the prognostic factors for overall survival (OS) and after recurrence survival (ARS). The toxicities of 30 patients receiving Re-RT were also assessed. RESULTS The median OS and ARS of the 130 recurrent patients were 21 months (1-164 months) and 6 months (1-142 months). The 1-, 2-, and 3-year OS rates were 81.5%, 39.2%, and 23.8%, respectively. Besides, the 1-, 2-, and 3-year ARS rates were 30.0%, 10%, and 6.2%. Multivariate analysis showed that Re-RT ± chemotherapy (p = 0.043) and chemotherapy alone (p < 0.001) and esophageal stents (p = 0.004) were independent prognostic factors for OS. The median OS of 30 patients treated with Re-RT were significantly better than that of 29 patients treated with chemotherapy (34.5 months vs. 22 months, p = 0.030). Among 30 ESCC patients treated with Re-RT, the median OS and ARS were 34.5 months (range 12-163 months) and 6 months (range 1-132 months), respectively. The recurrence-free interval (RFI) (> 12 months) and initial radiation dose (> 60 Gy) were significantly associated with improved OS. Radiation esophagitis (Grade 1-2) occurred in 16 patients and myelosuppression (Grade1-2) occurred in 10 patients. Grade 3 toxicities (radiation esophagitis and myelosuppression) were only 13.3%. There were no grade 4 toxicities. CONCLUSION Our results demonstrated that IMRT/VMAT-based Re-RT was an effective therapeutic option for ESCC patients with local primary-recurrence compared with chemotherapy alone or without any treatment. Re-RT had improved OS but unfavorable ARS.

Abstract
Locoregional recurrences following surgery for esophageal cancers represent a significant clinical problem with no standard recommendations for management. We conducted this systematic review and meta-analysis with the objective of studying safety and efficacy of salvage radiotherapy in this setting. All prospective and retrospective cohort studies, which studied patients who developed locoregional recurrence following initial radical surgery for esophageal cancer and subsequently received salvage radiation therapy (RT)/chemoradiation with all relevant information regarding survival outcome and toxicity available, were included. The quality of eligible individual studies was assessed using the Newcastle-Ottawa Scale score for risk of bias. R package MetaSurv was used to obtain a summary survival curve from survival probabilities and numbers of at-risk patients collected at various time points and to test the overall heterogeneity using the I2 statistic. Thirty studies (27 retrospective, 3 prospective) published from 1995 to 2020 with 1553 patients were included. The median interval between surgery and disease recurrence was 12.5 months. The median radiation dose used was 60 Gy and 57% received concurrent chemotherapy. The overall incidence of acute grade 3/4 mucositis and dermatitis were 8 and 4%, respectively; grade 3/4 acute pneumonitis was reported in 5%. The overall median follow-up of all studies included was 27 months. The 1-, 2- and 3-year overall survival (OS) probabilities were 67.9, 35.9 and 30.6%, respectively. Factors which predicted better survival on multivariate analysis were good PS, lower group stage, node negativity at index surgery, longer disease-free interval, nodal recurrence (as compared to anastomotic site recurrence), smaller disease volume, single site of recurrence, RT dose >50 Gy, conformal RT, use of concomitant chemotherapy and good radiological response after radiotherapy. Salvage radiotherapy with or without concomitant chemotherapy for locoregional recurrences after surgery for esophageal cancer is safe and effective. Modern radiotherapy techniques may improve outcomes and reduce treatment-related morbidity.

Abstract
BACKGROUND Salvage concurrent chemoradiotherapy is effective against locoregional recurrence after curative resection of esophageal squamous cell carcinoma. However, there is no consensus on its application. We investigated the outcomes of salvage concurrent chemoradiotherapy (60 Gy in 30 fractions) with three-dimensional conformal radiotherapy and 5-fluorouracil/platinum-based chemotherapy. METHODS We retrospectively investigated the outcomes and prognostic factors in 51 patients with esophageal squamous cell carcinoma treated with salvage concurrent chemoradiotherapy. RESULTS The median follow-up was 17.5 (range, 2.8-116.1) months. The overall response, complete response, and partial response rates were 74.5%, 49.0%, and 25.5%, respectively. The median progression-free survival was 8.2 months; the 3-year progression-free survival rate was 22.9%. The median overall survival was 23.1 months; the 3-year overall survival rate was 40.7%. Overall survival was significantly longer in patients with a complete response than in those without (median overall survival: not reached vs. 15.3 months); 3-year overall survival rate: 62.5% vs. 20.3% (hazard ratio: 0.222; P < 0.001). Multivariate analysis showed that the independent prognostic factor for overall survival was < 25 mm longest diameter of metastatic lymph nodes (hazard ratio: 3.71). CONCLUSIONS Salvage concurrent chemoradiotherapy (60 Gy in 30 fractions) with three-dimensional conformal radiotherapy and 5-fluorouracil/platinum-based chemotherapy was an effective and safe treatment for locoregional recurrence after curative resection of esophageal squamous cell carcinoma, especially in those approaching a complete response. Additionally, a shorter longest diameter of metastatic lymph nodes may be associated with better long-term survival.

Abstract
Background There are no standard therapeutic strategies for local lymph node (LN) recurrence after radical resection of oesophageal squamous cell carcinoma (ESCC), and prognostic risk factors remain controversial. We assessed clinical outcomes and prognostic factors of chemoradiotherapy (CRT) or radiotherapy (RT) for LN recurrence of ESCC after curative resection. Methods A total of 117 ESCC patients with LN recurrence after radical resection receiving salvage treatment at our hospital were retrospectively reviewed from 2014 to 2017. Overall survival (OS) was estimated using the Kaplan–Meier method; clinical characteristics were assessed using the Log rank test in the univariate analysis. Multivariate prognostic analysis was performed using the Cox proportional hazard model. Results With a median follow-up of 19 months, the 1-, 2- and 3-year OS rates were 75.2%, 40.2% and 27.4%, respectively. The median survival time (MST) was 19.0 months. On univariate analysis for OS, pathological TNM stage, number of LN metastasis, LN maximum (Max) diameter, salvage treatment mode and tumor response were significantly associated with OS (P = 0.0074, P = 0.015, P = 0.0011, P = 0.028, P < 0.000, respectively). On multivariate analysis, tumor response [Response vs No-response hazard ratio (HR), 2.43; 95% confidence interval (CI), 1.53–3.90, P < 0.000] and LN Max diameter (≤28 mm vs >28 mm HR, 2.07; 95% CI, 1.33–3.32, P = 0.012) were independent prognostic factors. Conclusion Salvage CRT or RT was safe and effective for treating LN recurrence after radical resection in ESCC. Patients with the small LN Max diameter (≤28 mm) and obtained response after salvage therapy appeared to achieve long-term OS.

A re-irradiation dose of 55-60 Gy improves the survival rate of patients with local recurrent esophageal squamous cell carcinoma after radiotherapy. Radiat Oncol 2021; 16:100. [PMID: 34103059 PMCID: PMC8186078 DOI: 10.1186/s13014-021-01828-z] [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: 08/12/2020] [Accepted: 06/01/2021] [Indexed: 12/04/2022] Open
Abstract
Introduction Local recurrence (LR) is clinical challenge in the treatment of esophageal squamous cell carcinoma (ESCC). The current study aimed to determine the optimal re-irradiation dose for local recurrent esophageal squamous cell carcinoma (LRESCC) following radical (chemo) radiotherapy. Methods We retrospectively analyzed 125 patients with LRESCC after receiving initial radiotherapy. For radiotherapy treatment, 58 patients were assigned to low-dose (LD) group (50–54 Gy) and 67 were assigned to the high-dose (HD) group (55–60 Gy). The response rate (complete + partial response), 1-, 2- and 3-year survival rate, and toxicity were recorded. We then analyzed the impact of different radiotherapy doses and combination chemotherapy on the survival of patients with LRESCC. Results After re-irradiation, the 1-, 2- and 3-year survival rates in the LD and HD groups were 48.3%, 24.1% and 10.3% and 61.2%, 34.3% and 19.4% in the HD group, respectively, and the difference in overall survival rate between the two groups were significant (P < 0.05). The median survival time of patients receiving radiotherapy alone was 9 months in the LD group and 15 months in the HD group (P < 0.05). The survival rate of patients treated with chemoradiotherapy was higher than that of patients treated with radiotherapy alone in the LD group. However, chemoradiotherapy showed no advantage over radiotherapy alone in the HD group. In addition, the incidence of radiation esophagitis, the most common toxicity, was higher in the HD group compared to the LD group (68.7% vs 58.6%). Multivariate analysis demonstrated that re-irradiation dose was an independent favorable prognostic factor in patients with LRESCC. Conclusion Higher re-irradiation dose (55–60 Gy) can improve the long-term survival of patients with LRESCC after radiotherapy, with tolerable toxicity.

Abstract
Background Re-irradiation (re-RT) has the active effect of relieving clinical symptoms and prolonging the survival of patients with recurrent esophageal squamous cell carcinoma (ESCC). However, the optimal re-RT dose is still uncertain. Here, we analyzed the prognostic factors associated with survival and explored the optimal re-RT dose for patients with recurrent ESCC following definitive radiotherapy. Patients and methods The data of 47 patients with recurrent ESCC who were retreated between 2010 and 2014 were retrospectively analyzed. All patients received a radiation dose > 50 Gy during the primary treatment. The median time to recurrence after primary radiotherapy was 26 months (range 6–120 months). All patients had in-field recurrence in the esophagus. Recurrence within the local site was observed in 37 patients (78.7%), and recurrence in both the local site and regional nodes were observed in 10 patients (21.3%). All patients received 3D conformal re-RT with a median dose of 58 Gy (range 26–64 Gy). Chemotherapy was sequentially used in 27.7% of the patients. Survival curves were constructed according to the Kaplan-Meier method and were compared by log-rank tests. The factors predictive of survival were identified with univariate and multivariate analyses. Results Dysphagia relief after re-RT was achieved in 20 of the 35 symptomatic patients (57.1%). The median survival time (MST) of all patients was 17 months, and the 1-, 2-, 3- and 5-year overall survival (OS) rates were 72.3, 25.5, 17.0 and 2.1%, respectively. In the univariate analysis, an Eastern Cooperative Oncology Group Performance Status (ECOG-PS) of 0–1 (P = 0.014), recurrence at the local site (P = 0.048), time to recurrence ≥24 months (P = 0.006) and re-RT dose ≥50 Gy (P < 0.001) were associated with favorable OS. In the multivariate analysis, only re-RT dose was an independent factor for OS (P = 0.007). Severe complications were observed in 7 patients, two of whom received a re-RT dose > 60 Gy. Conclusion Our results demonstrated that patients with recurrent ESCC following definitive radiotherapy had unfavorable OS. Re-RT could be considered a feasible and effective treatment modality. A re-RT dose > 50 Gy could improve the survival outcomes, and a dose > 60 Gy should be administered with caution due to the risk of severe complications.

Abstract
Background Patients with regional lymph node recurrence after radical resection of esophageal cancer have poor therapeutic outcomes. Currently, there is no standard treatment for regional lymph node recurrence, and its prognostic risk factors are not well-understood. This study retrospectively analyzed 83 patients with postoperative regional lymph node recurrence after radical resection of esophageal squamous cell carcinoma. The aim was to evaluate the clinical efficacy and prognostic factors of salvage radiotherapy with or without chemotherapy in these patients. Methods The survival and prognostic factors of 83 patients with esophageal squamous cell carcinoma with regional lymph node recurrence after radical surgery were retrospectively analyzed. All patients underwent radiotherapy, of which 74 patients received volumetric modulated arc therapy (VMAT), 9 patients received three-dimensional conformal radiation therapy (3DCRT), administered using a conventional segmentation protocol with a dose distribution range of 50.4–66.2Gy (median dose of 60Gy). In total, 41 patients received radiotherapy alone, 42 received radiotherapy combined with chemotherapy, and the concurrent chemotherapy regimen was mainly composed of either platinum or fluorouracil monotherapy, except for 4 patients who were given 5-fluorouracil plus platinum (FP) or paclitaxel plus platinum (TP). Results The median follow-up time was 24 (range, 9–75) months. The overall survival (OS) rates at 1 year, 2 years, 3 years, and 5 years were 83.0, 57.1, 40.1, and 35.1%, respectively. The median overall survival (OS) time was 18 (range, 5–75) months. The 3-year survival rate was 47.5% in patients with radiation alone and 41.9% in patients receiving concurrent chemoradiotherapy(p = 0.570), while the response rate (CR + PR) in those two groups was 73.2 and 91.4%, respectively. By multivariate analysis of OS, age (worse in younger patients, p = 0.034) was found to be significantly associated with disease prognosis. The commonly toxicities were esophagitis, neutropenia and anemia. 18% patients experienced grade 3 toxicity and no treatment-related death occurred. Conclusions These results of this retrospective analysis suggest that radiotherapy with or without chemotherapy is an effective and feasible salvage treatment for lymph node recurrence after radical resection of esophageal squamous cell carcinoma.

Abstract
Background The therapeutic strategies and prognostic risk factors in patients with lymph node (LN) recurrence of esophageal cancer remain controversial. We assessed clinical outcomes and prognostic factors related to the use of chemoradiotherapy (CRT) for LN recurrence of esophageal squamous cell carcinoma (ESCC) after curative resection. Methods We retrospectively evaluated survival and prognostic factors in 57 patients with LN recurrence of ESCC after curative resection. Patients received CRT using 5-fluorouracil plus cisplatin (FP) or docetaxel. Radiotherapy was delivered at 2 Gy (total dose, 60-66 Gy; median, 60 Gy). Results The median follow-up duration was 24 (range, 3-116) months. The overall survival (OS) rates at 2, 3 and 5 years were 43.7%, 36.9% and 27.6%, respectively. In the univariate analysis of OS, treatment with FP, a single LN recurrence, and a single regional recurrence were associated with a significantly better prognosis (P = 0.04, P = 0.027 and P = 0.0001, respectively). In the multivariate analysis, the combination chemotherapy regimen [hazard ratio (HR), 2.50; 95% confidence interval (CI), 1.23-5.07] and the number of the regional LNs with recurrence (HR, 5.76; 95% CI, 1.22-27.12) were independent prognostic factors. Conclusion Approximately 28% of ESCC patients with LN recurrence after curative resection could achieve long-term survival with CRT. Treatment with FP or patients with a single regional recurrence might improve the treatment outcome.

Abstract
Little evidence is available about survival rates in patients with recurrent disease after potentially curative surgery for esophageal or junctional cancer. Only in limited occasions, potentially curative salvage strategies are available. The aim of this study is to analyze survival rates and patterns of dissemination, and to identify independent prognostic factors in a consecutive series of patients who develop recurrent esophageal or junctional cancer. Between 1994 and 2015, patients who developed disease recurrence after neoadjuvant chemo(radio)therapy followed by radical esophagectomy for esophageal or junctional cancer were retrospectively analyzed. The Kaplan-Meier estimates were performed to calculate and compare overall survival between patients with different patterns of dissemination and to compare between different treatment strategies. Furthermore, univariate and multivariate Cox-regression analyses were performed to identify independent prognostic factors for post recurrence survival. In this study, we included 219 patients. The median overall survival of all included patients was 3.2 months (range: 0.0-101.1 months). The median overall survival in patients with exclusively locoregional recurrence (n = 23, 10.8%) was 4.9 months (range: 0.1- 55.6) and 2.9 months (range: 0.0-101.1) in patients who had distant metastases (n = 189, 89.2%), P = 0.003. Patients who received treatment aimed at complete tumor eradication (n = 28, 13.7%) had a median overall survival of 13.6 months (range: 1.1-101.1) and palliative treated patients (n = 94, 46.1%) of 4.7 months (range: 0.3-25.6), P < 0.001. In a selected group of patients survival of more than 20 months was achieved. Univariate and multivariate Cox-regression analysis showed that a higher age at the diagnosis of recurrent disease (hazard ratio: 1.087, P ≤ 0.001), an irradical resection of the primary tumor (hazard ratio: 3.355, P = < 0.001), the number of positive lymph nodes after neoadjuvant therapy (hazard ratios: ypN2 = 1.724 (P = 0.024) and ypN3 = 2.082 (P = 0.028) and the presence of a single hematogenous distant metastases (hazard ratio: 2.281, P = 0.003) or more than one hematogenous distant metastasis (hazard ratio: 2.385, P = 0.005) were associated with a shorter postrecurrence survival. The prognosis of patients who develop recurrent esophageal or junctional cancer is poor. In a selected group of patients however relatively long survival can be achieved. This offers new perspectives to improve treatment strategies and survival rates.

Abstract
There is currently no consensus on salvage therapy for recurrent esophageal cancer. Salvage surgery is a well-established option for attaining long-term survival; however, it is associated with a high risk of perioperative morbidity and mortality. A total of 6 patients who underwent re-irradiation for recurrence of locoregional esophageal cancer following definitive chemoradiotherapy were investigated. The median interval between initial radiotherapy and re-irradiation was 17.4 months (range, 6.4-59.2 months). Re-irradiation salvage therapy was mostly administered with concurrent chemotherapy, which consisted of several cycles of nedaplatin on day 1 and oral S-1 administration on days 1-14. The median survival after re-irradiation was 13.6 months (range, 1.9-33.3 months). A total of 3 patients who completed hyperfractionated radiation therapy survived for >1 year. One patient has had no signs of recurrence or late radiation toxicity for >2 years. Severe acute hematological adverse events (AEs) occurred in 3 patients, including 1 case of grade 4 leukopenia. One severe late AE occurred in 1 patient, who developed grade 3 dysphagia and became permanently dependent on percutaneous endoscopic gastrostomy tube feeding. Salvage radiotherapy is considered to be a good treatment option for inoperable locoregional recurrent esophageal cancer. The results of the present study demonstrated that re-irradiation, with or without chemotherapy, for recurrent esophageal carcinoma after definitive chemoradiotherapy was tolerable and yielded reasonably satisfactory results.

Abstract
The microscopic identification of residual tumor tissue in the oral or aboral resection margins (R1 resection) of esophageal specimens following oncologic esophageal resection, increases the risk of tumor recurrence and disease-related morbidity. Esophageal resection with its associated risks is only meaningful, if an R0 situation can be safely achieved. The relevance of microscopic involvement of the circumferential resection margin (CRM) in esophageal carcinoma in its different definitions by the British and the American Societies of Pathology has up to now never been investigated in a prospective study. According to the German S3 guideline, radiochemotherapy should be performed in a postoperatively proven R1 situation, which cannot be converted by a curative extended re-resection into an R0 situation or in unfavorable conditions for an extended re-resection, independent of neoadjuvant therapy. In the case of an R1 situation in the region of the CRM, an extended re-resection is not simply possible on account of the anatomical conditions with corresponding limitations by the aorta and the spinal column, in contrast to extensions of the re-resection orally or aborally.

Abstract
BACKGROUND This study evaluated the treatment results of lymph node (LN) oligo-recurrence in esophageal cancer patients treated with salvage radiotherapy (RT) in a multi-institutional retrospective study. METHODS Eligibility criteria for this retrospective analysis were: the primary lesion of esophageal cancer was controlled; from one to five LN recurrences; total RT dose ≥45 Gy to exclude palliative RT; without recurrence other than LN; and salvage RT for LN recurrence was given between January 2000 and April 2015. The median follow-up time for the 93 living patients was 29.6 months. RESULTS Two hundred thirty-seven patients were matched in five hospitals. The 3-year overall survival (OS) was 37%, local control was 45%, progression-free survival was 24%, and esophageal cancer-specific survival was 42%. On univariate analysis for OS, combined chemotherapy (p = 0.000055), disease-free interval (DFI) ≥12 months (p = 0.0013), LN max diameter ≤22 mm (p = 0.0052), and Karnofsky performance status ≥80% (p = 0.030) were associated with a significantly better prognosis. On multivariate analysis, significant differences were seen for combined chemotherapy (p = 0.000018), DFI (p = 0.0027), and LN max diameter (p = 0.018). CONCLUSIONS LN oligo-recurrence following treatment for esophageal cancer was not a terminal-stage event. Moreover, cure may be possible by chemoradiation therapy with a long DFI (≥12 months) and small size (≤22 mm).

Abstract
Recurrent esophago-gastric junction adenocarcinoma is not a rare event and its correct management is still debated. Many approaches for the treatment of these patients exist, but only few studies compare the different techniques. Most of the studies are retrospectives series and describe the experiences of single institutions in the treatment of recurrent esophageal and esophago-gastric junction cancers. Nowadays surgery is still the main and only curative treatment. Other alternative palliative therapies could be endoscopic stent placement and balloon dilation, photodynamic therapy, thermal tumor ablation (laser photoablation and Argon plasma coagulation), radiation therapy and brachytherapy, and chemotherapy. The aim of this review is to investigate the different rates, patterns and timings of recurrence of this tumor, and to explain the various approaches used for the treatment of recurrent esophago-gastric junction cancer.

Outcomes of patients with squamous cell carcinoma of esophagus who did not receive surgical resection after neoadjuvant radiochemotherapy. TUMORI JOURNAL 2015; 101:263-7.

Abstract
AIMS AND BACKGROUND The primary objective was to assess the different reasons for refusal of surgical resection (SR) in patients with esophageal squamous cell cancer (ESCC), who were initially planned for neoadjuvant radiochemotherapy (N-RCT) + SR, but SR was not performed after N-RCT. METHODS AND STUDY DESIGN From 1988 to 2011, 311 patients with ESCC were treated with N-RCT in a tertiary referral center for esophageal diseases. Fifty-three patients were analyzed who received RCT with 40-45 Gy and concomitant chemotherapy in neoadjuvant intention, but in whom the treatment was stopped or switched to definitive RCT due to progression, patient decision, or new findings. RESULTS The reasons for refusal of SR for these 53 patients were as follows: (1) patients' or physicians' preference for the planned treatment was changed during the N-RCT, such that RCT was continued to a curative dose without a break (group 1, n = 23, 44%); (2) patients were restaged after 4 weeks, and the tumor board decided to continue RCT because R0 resection was unlikely and/or patients were medically unfit (group 2, n = 15, 28%); (3) patients refused continuation of any treatment (group 3, n = 15, 28%). Refusal of SR was significantly more likely in patients with longitudinal tumor dimension >8 cm and those with an Eastern Cooperative Oncology Group performance status score of 2. Median follow-up time from the start of N-RCT was 57 months (range 1-137 months). The survival rates at 2 and 5 years were 36 ± 7% and 27 ± 7%, respectively. Group 1 had significantly longer survival. CONCLUSIONS The planned N-RCT+SR could not be completed in a considerable number of patients in a tertiary referral center. More strict selection criteria for multimodality treatment including SR could spare some of these patients an incomplete treatment and probably lead to increased utilization of definitive RCT.

Abstract
PURPOSE The aim of this study was to evaluate the salvage radiotherapy outcome in patients with local recurrent esophageal cancer after radical radiochemotherapy (RCT). METHODS A total of 114 patients with local recurrent esophageal squamous cell carcinoma after initial radical RCT were retrospectively analyzed. Fifty-five (55) patients belonged to the salvage radiotherapy group (SR group) and 59 patients to the non-salvage radiotherapy group (NSR group). RESULTS The median survival time after-recurrence was 4 months in all patients. The 1, 2, 3 year overall survival (OS) rates were 83.6%, 41.8% and 21.8% respectively in the SR group, and 57.6%, 16.9%, and 8.5% in the NSR group. The 6-month and 1-year survival rates after-recurrence were 41.8% and 16.4% respectively in the SR group, and 11.9% and 3.4% respectively in the NSR group. A salvage radiation dose > 50 Gy after initial radical RCT, improved the survival of patients with local recurrent esophageal cancer. Three patients (5.45%) from the SR group showed more than 3-grade radiation pneumonitis. In addition, esophageal fistula/perforation was observed in 11 cases (20.0%) in the SR group and in 8 cases (13.6%) in the NSR group. CONCLUSIONS Salvage treatment after definitive RCT may improve the overall survival and survival after-recurrence of patients with local recurrent esophageal cancer.

Abstract
Background Acquired radioresistance of cancer is common after repeated irradiation and often leads to treatment failure. This study aimed to examine the effects of nimotuzumab on acquired radioresistance in human esophageal carcinoma cells and to investigate its underlying mechanisms. Methods The radioresistant human esophageal carcinoma cell line KYSE-150R was generated by using fractionated irradiation. KYSE-150R cells were pretreated with or without nimotuzumab before ionizing radiation. Cell growth and colony formation were measured to quantitate the effects of radiation. The γ-H2AX foci assay was employed to determine cellular DNA-repairing capacity. The phosphorylation of key molecules involved in the epidermal growth factor receptor (EGFR) signaling pathway and cellular DNA repair was measured by Western blot analysis. Results Nimotuzumab enhanced radiation-induced inhibition on cell growth and clonogenic survival in KYSE-150R cells. The average number of γ-H2AX foci increased in the irradiated cells treated with nimotuzumab. Nimotuzumab inhibited phosphorylation of the EGFR and its downstream molecules AKT and ERK. Phosphorylation of the DNA repair-related proteins DNA-PKcs, ATM, and RAD51 was also inhibited by nimotuzumab. Conclusions These results indicate that nimotuzumab can inhibit key cancer survival mechanisms, the EGFR signaling pathway, and DNA repair and thereby reverse acquired radioresistance in KYSE-150R cell line.

Abstract
The most optimal management for postoperative locoregional recurrence of oesophageal squamous cell carcinoma is still controversial. Several studies have reported the feasibility and efficacy of concurrent chemoradiotherapy (CCRT), mostly with three-weekly or four-weekly schedule of chemotherapy. However, treatment compliance was not quite satisfactory, probably due to treatment-related toxicities. Since CCRT with weekly chemotherapy regimens have demonstrated a favorable toxicity profile as well as promising survival in certain types of cancer, we aimed to evaluate the efficacy and toxicity of radiotherapy concurrently with weekly chemotherapy with 5-fluorouracil (5-FU) and platinum agents for patients with postoperative locoregional recurrence of oesophageal squamous cell carcinoma in our center. Twenty-seven consecutive patients who were diagnosed with postoperative locoregional recurrence of oesophageal squamous cell carcinoma and received CCRT with weekly chemotherapy of 5-FU and platinum agents were retrospectively analyzed. Our data showed that the present protocol of radiotherapy combined concurrently with weekly chemotherapy of 5-FU and platinum agents was a safe and effective salvage treatment for postoperative locoregional recurrence of oesophageal squamous cell carcinoma.

Abstract
PURPOSE The purpose of this article is to report the outcome of neoadjuvant radiochemotherapy (N-RCT) + surgery in patients with squamous cell carcinoma of the esophagus at a single institution. METHODS We retrospectively reviewed data from patients who were referred to our department for N-RCT. From 1988–2011, 103 patients were treated with N-RCT with cisplatin and/or 5-fluorouracil (5-FU). Group 1: (n = 55) from 1988–2006 with 39.6–40 Gy and 5-FU with (n = 17) or without cisplatin (n = 38). Group 2: from 2003–2010 with 44–45 Gy and 5-FU with (n = 40) or without cisplatin (n = 8). All patients underwent radical resection with reconstruction according to tumor location and 2-field lymph node dissection. The degree of histomorphologic regression was defined as grade 1a (pCR, 0 % residual tumor), grade 1b (pSTR, < 10 % residual tumor), grade 2 (10–50 % residual tumor), and grade 3 (> 50 % residual tumor). RESULTS Median follow-up time from the start of N-RCT was 100 months (range 2–213 months). The median overall survival (OS) for the whole cohort was 42 months and the 5-year OS was 45 ± 5 %. In the multivariate analysis, worse ECOG performance status (p < 0.001), weight loss > 10 % before the start of the N-RCT (p = 0.025), higher pT category (p = 0.001), and grade 2/3 pathologic remission (p < 0.001) were significantly associated with a poor OS. PCR and pSTR rates for group 1 were 36 % and 18 % compared to 53 % and 22 % for group 2 (p = 0.011). There was a tendency for a better outcome in group 2 patients without statistical significance. The 5-year OS, disease-free survival and recurrent-free survival were 36 ± 7 %, 35 ± 6, and 36 ± 7 % for group 1 and 55 ± 7, 49 ± 7, and 53 ± 7 in group 2 (p = 0.117, p = 0.124, and p = 0.087). There was no significant difference between the two groups considering the postoperative morbidity and mortality. CONCLUSION Higher radiation doses and more use of simultaneous cisplatin lead to higher pathologic response rates to N-RCT and may be associated with better survival outcomes. Prospective controlled trials are needed to assess the true value of intensified N-RCT regimens.

Abstract
PURPOSE The purpose of this work is to report the long-term outcomes of three-dimensional conformal radio(chemo)therapy in the curative management of esophageal squamous cell carcinoma (ESCC). PATIENTS AND METHODS A retrospective analysis of patients treated with radio(chemo)therapy between 1988 and 2011 at Klinikum rechts der Isar, Technische Universität München was performed. In all, 168 patients received radio(chemo)therapy for ESCC in curative intention. The median follow-up time was 91 months (range 1-212 months). There were 128 men and 40 women with a median age of 63 years. Selection criteria for radio(chemo)therapy were unfit for surgery and/or unresectable primary tumor (n = 146, 87 %) or patients' choice (n = 22, 13 %). The majority of the patients received a combination of cisplatin and 5-fluorouracil chemotherapy with 54 Gy in 30 fractions of radiotherapy. RESULTS The median overall survival (OS) was 20 months (95 % confidence interval 17-23 months). The OS at 2 and 5 years for the whole cohort was 41 ± 4 % and 22 ± 3 %, respectively. Forty patients (24 %) suffered an in-field recurrence. The most common acute nonhematologic toxicity >grade 2 was dysphagia in 35 % of the patients. Acute hematologic toxicity > grade 2 was recorded in 14 % of the patients. There was no grade 5 toxicity observed during the study. Poor ECOG performance status (0-1 vs. 2-3, HR = 1.70, p = 0.002) and weight loss ≥ 10 % before the start of therapy (HR = 1.99, p = 0.001) were among the factors significantly associated with poor OS in multivariate analysis. CONCLUSION Three-dimensional conformal definitive radio(chemo)therapy is well tolerated and leads to long-term survival in more than 20 % of patients with advanced disease and/or contraindication to surgery. However, 24 % in-field recurrence remains a major concern. Prospective trials are warranted to assess if a well-tailored conformal radiochemotherapy can improve the local control and obviate the need for surgical resection in patients with good general condition and potentially resectable tumors.

Abstract
AIM: To evaluate the efficacy and safety of S-1 combined with three dimensional conformal radiotherapy in the treatment of recurrent esophageal carcinoma after radiotherapy.
METHODS: Sixty-one esophageal carcinoma patients who recurred after they had received radical radiotherapy and were confirmed by pathology were divided into either a study group or a control group according to whether receiving S-1 or not. All patients received three dimensional conformal radiotherapy at 1.8-2.0 Gy each time, 5 fractions a week to a total dose of 45-55 Gy. The patients in the study group received S-1 at a dose of 60 mg/(m2•d) for 14 days, every 3 weeks, totally 6 wk when they started receiving re-radiotherapy. The control group merely received re-radiotherapy.
RESULTS: The complete response rate was 38.7% in the study group, and 26.7% in the control group (P > 0.05). The effective rate was 74.2% in the study group, and 46.7% in the control group (P < 0.05). The 1-, 2- and 3-year survival rates were 54.8%, 38.7% and 16.1% in the study group, and 43.3%, 20.0% and 6.7% in the control group (P < 0.05).
CONCLUSION: For recurrent esophageal carcinoma after radical radiotherapy, S-1 combined with three dimensional conformal radiotherapy can improve the efficacy and prolong survival period without a significant increase in acute adverse effects of radiotherapy.

Cisplatin- vs. oxaliplatin-based radiosensitizing chemotherapy for squamous cell carcinoma of the esophagus: a comparison of two preoperative radiochemotherapy regimens. Strahlenther Onkol 2014; 190:987-92. [PMID: 24737541 DOI: 10.1007/s00066-014-0661-x] [Citation(s) in RCA: 9] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/02/2014] [Accepted: 03/22/2014] [Indexed: 02/06/2023]
Abstract
PURPOSE To compare the outcomes of two neoadjuvant radiochemotherapy (N-RCT) regimens for squamous cell carcinoma of the esophagus (ESCC). METHODS The standard N-RCT regimen for ESCC at our institution between 2002 and 2011 was a total dose of 45 Gy (1.8-Gy fractions) with concomitant cisplatin (20 mg/m(2), days 1-5 and 29-33) and 5-fluorouracil (5-FU; 225 mg/m(2), 24 h continuous infusion on days 1-33). During the same period, a phase I/II study comparing the standard ESCC N-RCT protocol with a regimen identical except for the replacement of cisplatin with weekly oxaliplatin (40-50 mg/m(2)) was performed at our center. The standard regimen was used to treat 40 patients; 37 received the oxaliplatin regimen. All patients subsequently underwent radical resection with reconstruction according to tumor location and two-field lymph node dissection. RESULTS Median follow-up time from the start of N-RCT was 74 months (range 3-116 months). The two patient groups were comparable in terms of demographic and baseline tumor characteristics. R0 resection was achieved in 37/39 patients (95 %) in the cisplatin-based N-RCT group, compared to 24/37 (65 %) in the oxaliplatin-based group (p = 0.002). A pathological complete response (pCR) was seen in the resection specimens from 18/39 patients (46 %) in the cisplatin-based N-RCT group and in 8/37 (22 %) oxaliplatin-group patients. In the cisplatin group, 2- and 5-year overall survival (OS) rates were 67 ± 8 % and 60 ± 8 %, respectively (median OS 103 months), compared to 38 ± 8 % and 32 ± 8 %, respectively, for the oxaliplatin group (median OS 17 months; hazard ratio, HR 0.452; 95 % confidence interval, CI 0.244-0.839; p = 0.012). CONCLUSION Oxaliplatin-based N-RCT resulted in poorer outcomes in ESCC patients and should not routinely replace cisplatin-based N-RCT.

Abstract
The purpose of this retrospective study was to assess the efficacy of salvage radiation therapy (RT) or chemoradiation therapy (CRT) for locoregional recurrence (LR) of esophageal cancer after curative surgery. Forty-two patients who received salvage RT or CRT for LR of esophageal cancer after curative surgery between November 2000 and May 2012 were reviewed. The intended RT regimen was 60 Gy in 30 fractions combined with concurrent platinum-based chemotherapy. Median follow-up periods were 17.9 months for all evaluable patients and 28.2 months for patients still alive (19 patients) at analysis time. The 1-, 2-, and 3-year survival rates were 81.2 ± 6.4%, 51.3 ± 8.6%, and 41.1 ± 8.7%, respectively, with a median survival time of 24.3 ± 4.1 months. Out of 41 evaluable patients, 16 patients (39%) were alive beyond 2 years from salvage therapy. However, univariate analyses for overall survival showed no significant prognostic factor. Grade 3 or higher leukocytopenia was observed in 46% of the patients. Salvage RT or CRT for LR after surgery for esophageal cancer was safe and effective. These therapies may offer long-term survival to some patients. RT or CRT should be considered for LR.

Abstract
Background Lung radiation injury is a critical complication of radiotherapy (RT) for thoracic esophageal carcinoma (EC). Therefore, the goal of this study was to investigate the feasibility and dosimetric effects of reducing the lung tissue irradiation dose during RT for thoracic EC by applying volumetric modulated arc radiotherapy (VMAT) combined with active breathing control (ABC) for moderate deep inspiration breath-hold (mDIBH). Methods Fifteen patients with thoracic EC were randomly selected to undergo two series of computed tomography (CT) simulation scans with ABC used to achieve mDIBH (representing 80% of peak DIBH value) versus free breathing (FB). Gross tumor volumes were contoured on different CT images, and planning target volumes (PTVs) were obtained using different margins. For PTV-FB, intensity-modulated radiotherapy (IMRT) was designed with seven fields, and VMAT included two whole arcs. For PTV-DIBH, VMAT with three 135° arcs was applied, and the corresponding plans were named: IMRT-FB, VMAT-FB, and VMAT-DIBH, respectively. Dosimetric differences between the different plans were compared. Results The heart volumes decreased by 19.85%, while total lung volume increased by 52.54% in mDIBH, compared to FB (p < 0.05). The mean conformality index values and homogeneity index values for VMAT-DIBH (0.86, 1.07) were slightly worse than those for IMRT-FB (0.90, 1.05) and VMAT-FB (0.90, 1.06) (p > 0.05). Furthermore, compared to IMRT-FB and VMAT-FB, VMAT-DIBH reduced the mean total lung dose by 18.64% and 17.84%, respectively (p < 0.05); moreover, the V5, V10, V20, and V30 values for IMRT-FB and VMAT-FB were reduced by 10.84% and 10.65% (p > 0.05), 12.5% and 20% (p < 0.05), 30.77% and 33.33% (p < 0.05), and 50.33% and 49.15% (p < 0.05), respectively. However, the heart dose-volume indices were similar between VMAT-DIBH and VMAT-FB which were lower than IMRT-FB without being statistically significant (p > 0.05). The monitor units and treatment time of VMAT-DIBH were also the lowest (p < 0.05). Conclusions VMAT combined with ABC to achieve mDIBH is a feasible approach for RT of thoracic EC. Furthermore, this method has the potential to effectively reduce lung dose in a shorter treatment time and with better targeting accuracy.

Advanced techniques in neoadjuvant radiotherapy allow dose escalation without increased dose to the organs at risk : Planning study in esophageal carcinoma. Strahlenther Onkol 2013; 189:293-300.

Abstract
PURPOSE The goal of this work was to investigate the potential of advanced radiation techniques in dose escalation in the radiotherapy (RT) for the treatment of esophageal carcinoma. METHODS A total of 15 locally advanced esophageal cancer (LAEC) patients were selected for the present study. For all 15 patients, we created a 3D conformal RT plan (3D-45) with 45 Gy in fractions of 1.8 Gy to the planning target volume (PTV1), which we usually use to employ in the neoadjuvant treatment of LAEC. Additionally, a 3D boost (as in the primary RT of LAEC) was calculated with 9 Gy in fractions of 1.8 Gy to the boost volume (PTV2) (Dmean) to a total dose of 54 Gy (3D-54 Gy), which we routinely use for the definitive treatment of LAEC. Three plans with a simultaneous integrated boost (SIB) were then calculated for each patient: sliding window intensity-modulated radiotherapy (IMRT-SIB), volumetric modulated arc therapy (VMAT-SIB), and helical tomotherapy (HT-SIB). For the SIB plans, the requirement was that 95 % of the PTV1 receive ≥ 100 % of the prescription dose (45 Gy in fractions of 1.8 Gy, D95) and the PTV2 was dose escalated to 52.5 Gy in fractions of 2.1 Gy (D95). RESULTS The median PTV2 dose for 3D-45, 3D-54, HT-SIB, VMAT-SIB, and IMRT-SIB was 45, 55, 54, 56, and 55 Gy, respectively. Therefore, the dose to PTV2 in the SIB plans was comparable to the 3D-54 plan. The lung dose in the SIB plans was in the range of the standard 3D-45, which is applied for neoadjuvant radiotherapy. The mean lung dose for the same plans was 13, 15, 12, 12, and 13 Gy, respectively. The V5 lung volumes were 71, 74, 79, 75, and 73 %, respectively. The V20 lung volumes were 20, 25, 16, 18, and 19 %, respectively. CONCLUSION New treatment planning techniques enable higher doses to be delivered for neoadjuvant radiotherapy of LAEC without a significant increase in the delivered dose to the organs at risk. Clinical investigations are warranted to study the clinical safety and feasibility of applying higher doses through advanced techniques in the neoadjuvant treatment of LAEC.

Abstract
PURPOSE For recurrent esophageal cancer after primary definitive radiotherapy, no general treatment guidelines are available. We evaluated the toxicities and clinical outcomes of re-irradiation (re-RT) for recurrent esophageal cancer. MATERIALS AND METHODS We analyzed 10 patients with recurrent esophageal cancer treated with re-RT after primary definitive radiotherapy. The median time interval between primary radiotherapy and re-RT was 15.6 months (range, 4.8 to 36.4 months). The total dose of primary radiotherapy was a median of 50.4 Gy (range, 50.4 to 63.0 Gy). The total dose of re-RT was a median of 46.5 Gy (range, 44.0 to 50.4 Gy). RESULTS The median follow-up period was 4.9 months (range, 2.6 to 11.4 months). The tumor response at 3 months after the end of re-RT was complete response (n = 2), partial response (n = 1), stable disease (n = 2), and progressive disease (n = 5). Grade 5 tracheoesophageal fistula developed in three patients. The time interval between primary radiotherapy and re-RT was less than 12 months in two of these three patients. Late toxicities included grade 1 dysphagia (n = 1). CONCLUSION Re-RT of recurrent esophageal cancer after primary radiotherapy can cause severe toxicity.

Abstract
Adenocarcinomas of the gastroesophageal junction (GEJ) require multimodal treatment approaches to accomplish good local control and overall survival. While early T1/2 N0 tumors are treated with surgery alone, they are only found in a small subset of patients due to the lack of symptoms at this stage. Most of the tumors are detected in locally advanced stage where surgery alone results in disappointing outcome. Chemotherapy and/or chemoirradiation in the neoadjuvant setting are used to improve conditions for oncological surgery. They aim to achieve a downsizing with a pathological complete remission in the optimal case, improve R0 rates, and upfront treat microscopic metastatic tumor cells. The optimal neoadjuvant treatment approach-chemotherapy, chemoirradiation, or a multiphase approach of both-is yet unclear. Chemoirradiation can improve local control after incomplete surgery and is an important option for patients unfit for surgery. In addition, it enables symptom relief in a palliative setting, namely dysphagia, pain, or bleeding. While target volumes are very much standardized, new technologies as image-guided intensity-modulated radiotherapy (IG-IMRT) and particle therapy have the potential to improve the therapeutic window by minimizing toxicity. Challenges of the present and the future will be the combination of radiotherapy with other cytostatic drugs and modern targeted therapies. This should ideally be integrated into a multimodal setting that is able to identify risk groups according to predictive markers and tumor response, altogether leading to a personalized oncological approach.
