[PMID: 40415863 PMCID: PMC12099070 DOI: 10.1002/cai2.70010] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 11/22/2024] [Revised: 03/13/2025] [Accepted: 03/27/2025] [Indexed: 05/27/2025]
Abstract
As immunotherapy rises to prominence in cancer treatment, the therapeutic approach to esophageal cancer is undergoing significant transformations. This review emphasizes the necessity and optimization pathways for adjuvant postoperative radiotherapy after neoadjuvant therapy in patients with esophageal cancer in the immunotherapy era. Initially, we review the advancements in neoadjuvant treatment strategies. Subsequently, we evaluate the role of postoperative radiotherapy and the latest advancements in radiotherapy target volume definition and dose optimization following neoadjuvant therapy, as well as the implications of tumor immunotherapy on postoperative radiotherapy strategies. In conclusion, in the new era of immunotherapy, postoperative radiotherapy following neoadjuvant therapy for esophageal cancer holds significant value. Optimization strategies should follow individualized treatment principles and comprehensively consider tumor biology, patient status, and treatment resources to achieve optimal therapeutic outcomes and quality of life, thereby driving continuous innovation in esophageal cancer treatment.

Conversion from Radical Esophagectomy to Definitive Chemoradiotherapy After Neoadjuvant Chemotherapy for Advanced Esophageal Squamous Cell Carcinoma: Treatment Options Based on Chemotherapy Response. Ann Surg Oncol 2025; 32:3157-3166. [PMID: 39953348 DOI: 10.1245/s10434-025-16955-0] [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: 07/01/2024] [Accepted: 01/16/2025] [Indexed: 02/17/2025]
Abstract
BACKGROUND Radical esophagectomy after neoadjuvant chemotherapy (NAC) is the established strategy for resectable advanced esophageal cancer. However, some patients are converted to definitive chemoradiotherapy (dCRT) after NAC due to reasons such as their wishes or disease progression, and their prognosis remains uncertain. This study aimed to investigate the prognosis of patients who converted to dCRT. METHODS Patients who underwent NAC for resectable advanced esophageal squamous cell carcinoma between 2006 and 2020 were enrolled in this study retrospectively. The prognostic impact of subsequent treatment after NAC, planned surgery, or conversion to dCRT, was compared. RESULTS The study analyzed 686 patients, 70 who were converted to dCRT (dCRT group) and 616 who underwent surgery (Surg group). The dCRT group had a poorer prognosis than the Surg group, with more advanced tumors and poorer response to NAC. Therefore, further analysis was performed by categorizing patients as Responders (complete or partial response) and Non-responders (stable or progressive disease) to NAC. Among the Responders in the dCRT group, 76.7 % achieved a complete response, and the 5-year esophageal preservation survival rate was 66.9 %. The 5-year survival rates for Responders were 77.5 % in the dCRT group and 71.3 % in the Surg group. Multivariable analysis showed that dCRT did not worsen prognosis (P = 0.706; hazard ratio, 1.13; 95 % confidence interval, 0.59-2.16). Conversely, among the Non-responders, dCRT had a significantly poorer prognosis, with 5-year survival rates of 22.3 % in the dCRT group and 45.1 % in the Surg group (P < 0.001). CONCLUSIONS For patients responding to NAC, conversion to dCRT is considered a potential treatment option.

[PMID: 40066458 PMCID: PMC11891367 DOI: 10.3389/fimmu.2025.1548520] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/19/2024] [Accepted: 02/04/2025] [Indexed: 05/13/2025] Open
Abstract
Purpose The aim of this study was to investigate the survival benefits of postoperative radiotherapy (PORT) in patients with resectable esophageal cancer (EC) after neoadjuvant therapy in the Immunotherapy era. Methods The study was designed as a retrospective cohort study, which included a total of 733 patients with EC from the SEER database and a single-center cohort. We used propensity score matching (PSM) to equilibrate patient characteristics. The investigation incorporated Kaplan-Meier survival analysis and the Cox proportional risk regression model to assess outcomes. Results PORT did not significantly improve survival in the overall cohort, with a median overall survival of 38 months (p=0.56) in the SEER cohort and 39 months (p=0.75) in the Chinese cohort. However, in the immunotherapy subgroup, the Chinese cohort demonstrated that immunotherapy combined with PORT significantly improved survival (p=0.044).Multivariate Cox regression analysis demonstrated that patients aged 50-59 years (HR=5.93, 95% CI: 1.67-21.06) and those aged ≥70 years (HR=10.96, 95% CI:3.04-39.56) had increased survival risks compared to patients aged <50 years. Additionally, ypT3-4 stage patients exhibited a higher risk than those with ypT1-2 stage (HR=2.12, 95% CI: 1.14-3.93, p=0.017).Similar trends were observed in cT3-4 staging, R1/R2 and no immunotherapy. Lymph node metastasis also showed a progressive relationship with survival risk, with patients categorized as ypN1 (HR=1.90), ypN2 (HR=4.24), and ypN3 (HR=6.68) experiencing increasingly higher risks (p<0.05). Conclusions The collaborative effect of immunotherapy and PORT potentially enhances survival outcomes for patients with EC. However, further prospective research is essential to confirm our results.

Abstract
BACKGROUND The feasibility and outcomes of salvage endoscopic submucosal dissection (ESD) and ESD for metachronous esophageal squamous cell cancer (ESCC) inside the irradiated field are not clear. AIMS To explore the viability of ESD for ESCC in areas previously exposed to radiation, identify elements hindering successful ESD, assess prognosis, and elucidate considerations for follow-up. METHODS Patients with ESCC who underwent salvage ESD or ESD for metachronous ESCC within the previously irradiated field at Kanagawa Cancer Center between January 1, 2013, and December 31, 2023, were retrospectively investigated to evaluate patient and lesion characteristics and short- and long-term outcomes. RESULTS Thirty patients with 41 lesions were analyzed. The median age was 73 (52-88), and 93.3% were men. The middle thorax was the primary location, with flat lesions constituting 73.2%. In salvage ESD cases, the en bloc dissection rate was 91.3%, without adverse events. Conversely, the en bloc dissection rate in metachronous ESD was 100%, and aspiration pneumonitis and post-procedure stricture occurred in 12.5% and 12.5%, respectively. No lesion removed by salvage ESD recurred. During a median follow-up period of 685 (range 24-3061) days, 10 patients (52.6%) developed other organ malignancies, three died from pneumonia, and one died from pharyngeal cancer. The 5-year overall survival rate was 74.9%. No patient died of esophageal cancer. CONCLUSIONS Salvage and metachronous ESD are feasible and can achieve high en bloc resection rates and good local control. Screening for other organ malignancies after salvage ESD is indispensable. Preventing aspiration may also improve the prognosis.

Abstract
Esophageal cancer (EC) is one of the leading causes of cancer-related deaths globally. Surgery is the standard treatment for resectable EC after preoperative chemoradiotherapy or chemotherapy, followed by postoperative adjuvant chemotherapy in certain cases. Upper gastrointestinal endoscopy and computed tomography (CT) are predominantly performed to evaluate the efficacy of these treatments, but their sensitivity and accuracy for evaluating minimal residual disease remain unsatisfactory, thereby requiring the development of alternative methods. In recent years, interest has been increasing in using liquid biopsy to assess treatment responses. Liquid biopsy is a noninvasive technology for detecting cell components in the blood and other body fluids. It involves collecting a small sample of body fluid, which is then analyzed for the presence of components, including circulating tumor DNA (ctDNA), microRNA (miRNA), or circulating tumor cells (CTCs). Further, ctDNA and miRNA are analyzed with various techniques, including digital polymerase chain reaction (dPCR) and next-generation sequencing (NGS). CTCs are isolated by determining surface antigens using immunomagnetic techniques or by filtering the blood according to cell size and rigidity. Several studies indicate that investigating these materials helps predict EC prognosis and recurrence and possibly stratifies high-risk groups. Liquid biopsy may also apply to the selection of cases that have achieved a complete response through preoperative treatment to prevent surgery and preserve the esophagus, as well as identifying the suitability of postoperative chemotherapy and the timing of conversion surgery for unresectable EC. The potential of liquid biopsy to enhance treatment decisions will further advance EC treatment.

Abstract
BACKGROUND The COVID-19 pandemic had a profound impact on cancer screening, diagnosis, and treatment procedures. We speculated that during the COVID-19 pandemic, sufficient medical resources were maintained in board-certified hospitals, resulting in favorable short-term outcomes, whereas hospital functions in non-board-certified hospitals declined, leading to mortality increase. The aim of this study is to investigate the impact of COVID-19 pandemic on short-term outcomes after esophagectomy, based on the scale of the facilities. METHODS Data of patients who underwent esophagectomy for esophageal cancer between January 2018 and December 2022 were analyzed using the National Clinical Database (NCD) of Japan. We selected the Authorized Institutes for Board-certified Esophageal Surgeons (AIBCESs) certified by the Japan Esophageal Society (JES) at the hospital level for evaluating the difference in outcomes between institutions. Operative mortality rates and other morbidities were evaluated using the standardized mortality and morbidity ratio (SMR, the ratio of the number of observed patients to the expected number of patients). RESULTS Within the study period, the annual mean operative mortality rate was higher in non-AIBCESs than in AIBCESs. The SMR showed no significant difference after the COVID-19 pandemic in non-AIBCES for mortality, as well as that in AIBCES. CONCLUSIONS In non-AIBCESs, no worsening of results caused by the COVID-19 pandemic was observed despite the shortage of medical resources. Our findings highlighted the high quality of esophageal surgery in Japan during the COVID-19 pandemic, a critical situation with limited medical resources.

Abstract
BACKGROUND Patients with esophageal squamous cell carcinoma (ESCC) with distant metastasis were treated with systemic chemotherapy. Recent advances in multimodal treatments have made conversion therapy a viable option for patients with incurable ESCC. OBJECTIVE We aimed to assess the safety and efficacy of conversion therapy for ESCC with distant metastases. METHODS Conversion therapy was defined as surgery or chemoradiotherapy (CRT) used to cure tumors that were previously considered incurable because of distant metastasis. We conducted a retrospective review of patients who underwent ESCC conversion therapy and assessed the treatment outcomes, including adverse events and survival rates. RESULTS A total of 147 patients from 22 institutions were included. Systemic chemotherapy was initially administered to all patients. The most common M1 factor was the para-aortic lymph node, accounting for 55% of cases. Following the initial treatment, 116 patients underwent surgery, with 31 receiving CRT as conversion therapy. Postoperative complications in surgery patients included pneumonia (16%), anastomotic leakage (7%), and recurrent laryngeal nerve palsy (6%). During CRT, 18% of patients developed grade 3 or higher non-hematological toxicities. The 5-year overall survival (OS) rate was 31.7%. Pathological responders had significantly longer OS than non-responders (hazard ratio 0.493, p = 0.012). The distribution of distant metastasis, regimen type, clinical response, and conversion therapy modality did not have a significant impact on OS. CONCLUSIONS Conversion therapy can be safely performed for ESCC with distant metastasis and has a favorable prognosis.

Definitive-dose adjuvant radiotherapy following endoscopic submucosal dissection for superficial esophageal cancer. J Gastroenterol 2025; 60:32-42. [PMID: 39446142 DOI: 10.1007/s00535-024-02156-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/19/2024] [Accepted: 10/02/2024] [Indexed: 10/25/2024]
Abstract
BACKGROUND Prophylactic chemoradiation therapy (CRT) using 40-41.4 Gy post-endoscopic submucosal dissection (ESD) for clinical T1N0M0 esophageal cancer reportedly yields favorable outcomes. However, it cannot completely prevent locoregional lymph node (LN) metastases. We retrospectively analyzed outcomes and adverse events associated with our dose-escalated treatment regimen (definitive-dose radiotherapy [RT] of 50-61.2 Gy, with/without chemotherapy) for these patients, and predictors of progression-free survival (PFS) and overall survival (OS). METHODS Between 2006 and 2018, 44 consecutive patients (42 men and 2 women; median age, 70 years) who underwent definitive-dose RT post-ESD and had a pathological depth of the muscularis mucosa with lymphovascular invasion (LVI) or the upper-middle submucosal third at our institution were included. We excluded patients who could not obtain a margin-free resection by ESD. If feasible, systemic chemotherapy with 5-fluorouracil plus high- or low-dose cisplatin or nedaplatin was administered concurrently. RESULTS Five-year PFS, OS, and disease-specific survival rates were 78.8%, 88.4%, and 97.7%, respectively. Six metachronous esophagus (14%), two locoregional LN within the irradiated area with a prophylactic dose of 41.4 Gy (5%), and two locoregional LN plus liver (5%) recurrences occurred. No LN recurrence occurred within the definitive dose of ≥ 50 Gy in the irradiated area. Metachronous esophageal recurrence involved areas receiving ≥ 50 Gy. Univariate and multivariate analyses revealed that age was an independent prognostic factor for both PFS and OS. CONCLUSIONS Definitive-dose RT/CRT post-ESD could provide favorable locoregional LN control and PFS/OS regardless of patient characteristics, including pathological findings and chemotherapy regimen/course, except for age. These results need to be interpreted carefully given several limitations, therefore, definitive-dose RT/CRT should be conducted with caution in clinical practice until high-quality prospective clinical trials evaluating the effectiveness and safety.

Abstract
PURPOSE This study aimed to assess the viability of definitive chemoradiotherapy (dCRT) as an organ-preservation strategy for remarkable responders who were downstaged to stage IA after receiving induction chemotherapy for resectable esophageal squamous cell carcinoma (ESCC). METHODS AND MATERIALS Chemotherapy-naïve patients with resectable ESCC (stage IB-III, Union for International Cancer Control, International Cancer Control seventh edition) were eligible for the study. All patients received 3 cycles of docetaxel, cisplatin, and 5-FU (DCF) therapy (docetaxel 75 mg/m2 on day 1, cisplatin 75 mg/m2 on day 1, and 5-fluorouracil [5-FU] 750 mg/m2 on days 1-5, repeated every 3 weeks). Remarkable response was defined as a reduction in the tumor to T1, metastatic lymph nodes <1 cm on the short axis, and downstaging to stage IA after 3 cycles of DCF therapy. Remarkable responders then underwent dCRT, which included 2 courses of cisplatin 75 mg/m2 and 5-FU 1000 mg/m2 on days 1 to 4, repeated every 4 weeks, along with 50.4 Gy of concurrent radiation therapy. The primary endpoint was 1-year progression-free survival in remarkable responders following DCF therapy and subsequent dCRT. Secondary endpoints included 3-year overall survival (OS) and esophagectomy-free survival. RESULTS Of the 92 patients registered, 90 were analyzed. A remarkable response to 3 courses of DCF therapy was observed in 58.4% of patients. Among these responders, 89.8% achieved a complete response after dCRT. During the median follow-up period of 33 months (range, 1-85 months), the 1-year progression-free survival was 89.8% (95% confidence interval [CI], 77.2%-95.6%, primary endpoint), and the 3-year OS was 83.7%. The 3-year OS and esophagectomy-free survival rates in the analysis group were 74.1% and 45.3%, respectively. An 18F-fluorodeoxyglucose-positron emission tomography response after 2 courses of DCF therapy was significantly associated with OS (P = .0049). CONCLUSIONS In patients with resectable ESCC, dCRT for remarkable responders downstaging to stage IA after induction chemotherapy with 3 courses of DCF therapy is a feasible treatment option and provides an optimizing organ-preservation strategy of chemotherapy-based selection.

Abstract
Purpose This study aimed to examine the individualized neoadjuvant therapies for operable esophageal cancer. Methods and Materials Data of 95,444 patients diagnosed with esophageal cancer between 2010 and 2017 were collected from the Surveillance, Epidemiology, and End Results database. The effectiveness of neoadjuvant chemoradiotherapy (nCRT), neoadjuvant chemotherapy (nCT), and surgery alone was compared in patients with stage II esophageal cancer. Patients with stage III disease were divided into "local invasive type" group (type I, T3N1M0, T4N0-1M0) and "regional metastatic type" group (type II, T1-2N2-3M0) according to the tumor invasion pattern. The effectiveness of nCRT and nCT in different patterns was compared. Results In 2,706 patients with stage II disease, a statistical difference was observed in the overall survival (OS) between nCRT (85.1%), nCT (3.0%), and surgery alone (11.9%, P<0.001, median OS (mOS): 54 vs 41 vs 24 months). Meanwhile, 3,303 patients with stage III disease who received nCRT were included in the propensity score matching. A statistical difference was observed in the OS between "Type I" (n = 217) and "Type II" (n = 217, P = 0.023, mOS: 45 VS 28 months). Among 93 patients with stage III receiving nCT, those with "Type II" (23.7%) showed a greater potential benefit from nCT than those with "Type I" (76.3%, P = 0.686, mOS: 51 vs 40 months). Conclusions nCRT is recommended for stage II esophageal cancer. In patients with stage III, those with "local invasive type" may greatly benefit from nCRT, while those with "regional metastatic type" may greatly benefit from nCT.

Abstract
BACKGROUND A recent phase I/II study determined the optimal dose of definitive carbon-ion radiotherapy (CIRT) for cT1bN0M0 esophageal cancer. This study aimed to further confirm the efficacy and feasibility of the recommended dose fractionation of CIRT with long-term follow-up results in a larger sample size. METHODS This single center retrospective study evaluated patients with cT1bN0M0 esophageal squamous cell carcinoma treated with the recommended dose fractionation of 50.4 Gy relative biological effectiveness in 12 fractions, between 2012 and 2022. RESULTS Thirty-eight patients underwent CIRT at our hospital. Although eight (21.1%) patients were older than 80 years, 15 (39.5%) had high surgical risk, and seven (18.4%) were at high risk for chemotherapy, all patients underwent CIRT as scheduled. Grade 3 esophagitis occurred in eight (21.1%) patients and grade 3 pneumonia in one (2.6%) patient in this study, but no grade 4 adverse events occurred. The only grade 3 late adverse event was pneumonia in one patient (2.6%). The 5-year overall survival rate, local control rate, and disease-free survival rates were 76.6% (95% CI, 90.9-62.4), 74.9% (95% CI, 90.7-59.0), and 66.4% (95% CI, 83.3-49.5), respectively. Additionally, post CIRT recurrence was as follows: seven (18.4%) patients had recurrence in another part of the esophagus, three (7.9%) in the primary site, three (7.9%) in lymph nodes outside the irradiated area, and one (2.6%) patient had liver metastasis. CONCLUSIONS Our study demonstrates that CIRT using the recommended dose fractionation is feasible and effective for cT1bN0M0 esophageal squamous cell carcinoma.

Abstract
BACKGROUND Proton-based, definitive chemoradiotherapy (P-CRT) for esophageal squamous cell carcinoma (ESCC) previously showed comparable survival outcomes with the surgery-based therapy, i.e., neoadjuvant chemotherapy followed by esophagectomy (NAC-S), in a single-institutional study. This study aimed to validate this message in a Japanese multicenter study. METHODS Eleven Japanese esophageal cancer specialty hospitals have participated. A total of 518 cases with clinical Stage I-IVA ESCC between 2010 and 2019, including 168 P-CRT and 350 NAC-S patients, were enrolled and long-term outcomes were evaluated. Propensity-score weighting analyses with overlap weighting for confounding adjustment were used. RESULTS The 3-year overall survival (OS) of the P-CRT group was equivalent to the NAC-S group (74.8% vs. 72.7%, hazard ratio [HR]: 0.87, 95% confidence interval [CI]: 0.61-1.25). Although, the 3-year P-CRT group progression-free survival (PFS) was inferior to the NAC-S group (51.4% vs. 59.6%, HR 1.39, 95% CI 1.04-1.85), the progression P-CRT group cases showed better survival than the NAC-S group (HR 0.58, 95% CI 0.38-0.88), largely because of salvage surgery or endoscopic submucosal dissection for local progression. The survival advantage of P-CRT over NAC-S was more pronounced in the cT1-2 (HR 0.61, 95% CI 0.29-1.26) and cStage I-II (HR 0.50, 95% CI 0.24-1.07) subgroups, although this trend was not evident in other populations, such as cT3-4 and cStage III-IVA. CONCLUSIONS Proton-based CRT for ESCC showed equivalent OS to surgery-based therapy. Especially for patients with cT1-2 and cStage I-II disease, proton-based CRT has the potential to serve as a first-line treatment.

Abstract
BACKGROUND Chemoradiotherapy (CRT) modulates the tumor immune microenvironment of multiple cancer types, including esophageal cancer, which potentially induces both immunogenicity and immunosuppression by upregulating the presentation of tumor-specific antigens and immune checkpoint molecules in tumors, respectively. The prognostic effects of immune modification by CRT in esophageal squamous cell carcinoma (ESCC) remain controversial because of the lack of detailed immunological analyses using paired clinical specimens before and after CRT. We aimed to clarify the immunological changes in the tumor microenvironment caused by CRT and elucidate the predictive importance of clinical response and prognosis and the rationale for the necessity of subsequent programmed cell death protein 1 (PD-1) inhibitor treatment. METHODS In this study, we performed a comprehensive immunological analysis of paired biopsy specimens using multiplex immunohistochemistry before and after CRT in patients with unresectable locally advanced ESCC. RESULTS CRT significantly increased the intra-tumoral infiltration and PD-1 expression of CD8+ T cells and conventional CD4+ T cells but decreased those of regulatory T cells and the accumulation of tumor-associated macrophages. Multivariate analysis of tumor-infiltrating T-cell phenotypes revealed that the density of PD-1+CD8+ T cells in the tumor after CRT could predict a confirmed complete response and favorable survival. CONCLUSIONS This study showed that CRT improved the immunological characteristics of unresectable locally advanced ESCC and identified the density of PD-1+CD8+ T cells as a predictive factor for prognosis. This finding supports the rationale for the necessity of subsequent PD-1 inhibitor treatment.

Abstract
This editorial comments on an article by Qu et al published in the World Journal of Gastrointestinal Oncology. It focuses on the importance of early detection of esophageal cancer, including recurrence or secondary malignancy after chemoradiotherapy (CRT). Endoscopic resection is the first choice for treatment for esophageal cancer remaining within the mucous membrane, while surgery or radical CRT are treatment options for advanced stages depending on the patient's general condition and desire. Although these treatments are potentially curative, they are more invasive than endoscopic resection. Early-stage esophageal cancer is often asymptomatic and difficult to detect. Uniform periodic endoscopy is unrealistic. Although less burdensome tests exist, including liquid biopsy and urinary biomarkers, these have not yet been widely used in clinical practice. Early detection is important after radical CRT because the local recurrence rate is higher than that after surgery. However, endoscopic resection or photodynamic therapy is indicated if detected in the early stages, and positive results have been reported. Early detection of esophageal cancer is crucial. Endoscopy is the main diagnostic method; however, new and less burdensome methods should be established to ensure early treatment for patients with esophageal cancer.

Abstract
BACKGROUND The optimal strategy for cervical advanced esophageal cancer remains controversial in terms of oncologic outcome as well as vocal and swallowing function. Recently, in East Asian countries, neoadjuvant chemotherapy (NAC) has been a standard strategy for advanced esophageal cancer. METHODS This study included 37 patients who underwent NAC, and 33 patients who underwent definitive chemoradiation therapy (dCRT) as larynx-preserving treatment for locally advanced cervical esophageal cancer from 2016 to 2021. This study retrospectively investigated outcomes, with comparison between NAC and dCRT for locally advanced cervical esophageal cancer. RESULTS Larynx preservation was successful for all the patients with NAC and dCRT. After NAC, the rate of complete or partial response was 78.4%, and 30 patients underwent larynx-preserving surgery. On the other hand, after dCRT, the complete response rate was 71.9%, and 4 patients underwent larynx-preserving salvage surgery. Overall survival (OS) and progression free survival were similar between the two groups. However, for the patients with resectable cervical esophageal cancer (cT1/2/3), the 2-year OS rate was significantly higher with NAC (79.9%) than with dCRT (56.8%) (P = 0.022), and the multivariate analyses identified only NAC and cN0, one of the two as a significantly independent factor associated with a better OS (NAC: P = 0.041; cN0, 1: P = 0.036). CONCLUSION The study showed that NAC as larynx-preserving surgery for resectable cervical esophageal cancer preserved function and had a better prognosis than dCRT. The authors suggest that NAC may be standard strategy for larynx preservation in patients with resectable cervical esophageal cancer.

Abstract
BACKGROUND In older patients, esophageal squamous cell carcinoma (ESCC) is difficult to treat using standard therapies, including surgery and cisplatin-based chemoradiotherapy. Paclitaxel (PTX) has radiosensitizing activity. We conducted a phase I trial of PTX combined with radiotherapy to establish a standard therapy for locally advanced ESCC in older patients. METHODS Enrollment was conducted at six centers in Japan from April 2016 to September 2019. The participants were aged ≥ 70 years, had locally advanced ESCC, and were intolerant to surgery or unwilling. A fixed 60-Gy radiation dose was administered in 30 fractions. PTX dosing levels started at 30 mg/m2 weekly for 6 weeks. Depending on the number of DLTs, the dose was set to be increased by 10 mg/m2 or switched to biweekly. A geriatric assessment was performed before treatment using the Geriatric-8 screening tool. The primary endpoint was dose-limiting toxicity (DLT). RESULTS We enrolled 24 patients (6 per group); DLT was observed in one (grade 4 hypokalemia), one (grade 3 aspiration), two (grade 3 radiodermatitis, grade 3 esophageal hemorrhage), and two (grade 3 anorexia, grade 5 pneumonitis) patients in the weekly PTX 30, 40, 50, and 60 mg/m2 groups, respectively. All adverse events, except death in the 60 mg/m2 group, showed reversible improvement, and the safety profile was considered acceptable. The 2-year survival and complete response rates were 40.0% and 54.2%, respectively. There was a significant difference in survival between favorable and unfavorable Geriatric-8 scores. CONCLUSIONS The recommended PTX dose with concomitant radiation was determined to be 50 mg/m2 weekly. Phase II trials at this dose are underway.

Survival outcome of esophagectomy and chemoradiotherapy for resectable esophageal squamous cell carcinoma in patients >75 years of age. Thorac Cancer 2024; 15:1656-1664. [PMID: 38898742 PMCID: PMC11260550 DOI: 10.1111/1759-7714.15329] [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: 03/13/2024] [Revised: 04/17/2024] [Accepted: 04/25/2024] [Indexed: 06/21/2024] Open
Abstract
BACKGROUND The gold standard for resectable, locally advanced esophageal squamous cell carcinoma (ESCC) is surgery-based treatment; however, it is unclear whether esophagectomy or chemoradiotherapy is suitable for older patients. This retrospective study aimed to identify the treatment outcomes of surgery-based therapy versus definitive chemoradiotherapy (dCRT) as an initial treatment for older patients with resectable, locally advanced ESCC. METHODS Data from 434 patients who received radical treatment for resectable, locally advanced ESCC were collected from January 2011 to December 2020. Of the patients >75 years of age, 49 underwent radical esophagectomy and 26 received dCRT. Survival was compared between the surgery and dCRT groups. RESULTS The mean ages of the surgery and chemoradiotherapy groups were 77.3 and 78.8 years, respectively. Differences in overall survival (OS) between the two groups were not statistically significant (3-year OS: surgery 66.2%, dCRT 55.7%, p = 0.236). Multivariate analysis for OS showed a hazard ratio of 1.229 for dCRT versus surgery (90% confidence interval 0.681-2.217). OS did not differ between the groups in any of the performance statuses. For patients who were able to receive chemotherapy using fluorouracil and cisplatin, OS tended to be better in the surgery group, but the difference was not statistically significant (3-year OS: surgery 68.1%, dCRT 51.8%, p = 0.117). CONCLUSIONS There was no clear difference in survival outcome between surgery-based therapy and dCRT as an initial treatment for esophageal cancer in older patients. Either treatment may be an option for older patients.

Abstract
BACKGROUND Salvage esophagectomy for residual tumor and localized relapses after definitive chemoradiotherapy (dCRT) for patients with esophageal cancer is associated with a high rate of postoperative complications and in-hospital mortality. In addition, there are many controversial issues associated with salvage esophagectomy, such as the acceptability of minimally invasive surgery and the need for prophylactic dissection of mediastinal lymph nodes. The aim of this study was to evaluate the safety and usefulness of thoracoscopic salvage esophagectomy with prophylactic mediastinal lymph node dissection. METHODS The study included 31 patients who underwent thoracoscopic salvage esophagectomy with prophylactic mediastinal lymph node dissection after dCRT between 2013 and 2022 (salvage patients) and 610 nonsalvage patients who underwent conventional thoracoscopic esophagectomy during the same time period. RESULTS Differences between the median ages and sexes of the 2 patient groups were not significant. The dominant location of tumors in the salvage patients was the upper thoracic esophagus. More salvage patients had clinical T4 disease. The salvage patients had a lower median number of retrieved mediastinal lymph nodes than the nonsalvage patients. The differences between the rates of R0, postoperative complications, and in-hospital deaths in the 2 patient groups were not significant. The 3-year overall survival (OS) rates for the salvage patients were 73%, with 3-year OS rates for R0 vs non-R0 of 81% vs 0%, p < 0.01 and pN0 vs pN1-3 of 89% vs 49%, p < 0.01. CONCLUSION Regarding short-term outcomes, prophylactic mediastinal lymph node dissection for patients undergoing thoracoscopic salvage esophagectomy was as safe as prophylactic dissection for patients undergoing conventional thoracoscopic esophagectomy. R0 surgery and pN0 are important factors for long-term survival in patients undergoing thoracoscopic salvage esophagectomy.

Abstract
Oesophageal squamous cell carcinoma is a common malignancy worldwide. Definitive chemoradiotherapy is the standard treatment for patients with resectable stage oesophageal squamous cell carcinoma who cannot undergo surgery, as well as those with locally advanced unresectable oesophageal squamous cell carcinoma. However, it has several disadvantages such as poor survival, radiation-related toxicities and severe and lethal complications related to salvage treatment for residual or recurrent disease. Numerous clinical trials on chemoradiotherapy have been conducted to confirm the optimal combination of irradiation and chemotherapy. For advanced disease, multimodal treatment strategies including salvage surgery are essential. Palliative chemoradiotherapy is also crucial for dysphagia in locally advanced oesophageal squamous cell carcinoma with or without metastatic lesions. Recently, the synergistic mechanism of radiotherapy combined with immunotherapy has been reported. Early phase clinical trials suggest that a combination of immunotherapy and chemoradiotherapy can improve clinical outcomes with manageable side effects, but further investigations are needed. Here, we reviewed the existing clinical data and current development of chemoradiotherapy combined with immunotherapy in patients with oesophageal squamous cell carcinoma.

Abstract
In Japan, standard of care of the patients with resectable esophageal cancer is neoadjuvant chemotherapy (NAC) followed by esophagectomy. Patients unfitted for surgery or with unresectable locally advanced esophageal cancer are generally indicated with definitive chemoradiotherapy (CRT). Local disease control is undoubtful important for the management of patients with esophageal cancer, therefore endoscopic evaluation of local efficacy after non-surgical treatments must be essential. The significant shrink of primary site after NAC has been reported as a good indicator of pathological good response as well as favorable survival outcome after esophagectomy. And patients who could achieve remarkable shrink to T1 level after CRT had favorable outcomes with salvage surgery and could be good candidates for salvage endoscopic treatments. Based on these data, "Japanese Classification of Esophageal Cancer, 12th edition" defined the new endoscopic criteria "remarkable response (RR)", that means significant volume reduction after treatment, with the subjective endoscopic evaluation are proposed. In addition, the finding of local recurrence (LR) at primary site after achieving a CR was also proposed in the latest edition of Japanese Classification of Esophageal Cancer. The findings of LR are also important for detecting candidates for salvage endoscopic treatments at an early timing during surveillance after CRT. The endoscopic evaluation would encourage us to make concrete decisions for further treatment indications, therefore physicians treating patients with esophageal cancer should be well-acquainted with each finding.

Abstract
Chemoradiotherapy has been considered as one of the standard treatment options for clinical T1bN0M0 esophageal squamous cell carcinoma with organ preservation. However, 20% of patients develop locoregional recurrence after chemoradiotherapy, which requires salvage treatment including salvage surgery and endoscopic resection. Salvage surgery can cause complications and treatment-related death. Interestingly, chemoradiotherapy with elective nodal irradiation has been reported to reduce the locoregional recurrence of advanced esophageal squamous cell carcinoma. Hence, we are conducting a clinical trial to confirm whether modified chemoradiotherapy with elective nodal irradiation was superiority to that without elective nodal irradiation for the patients with cT1bN0M0 esophageal squamous cell carcinoma. The primary endpoint is major progression-free survival, defined as the time from randomization to the date of death or disease progression, excluding successful curative resection through salvage endoscopic resection. We plan to enroll 280 patients from 54 institutions over 4 years. This trial has been registered in the Japan Registry of Clinical Trials (jRCTs031200067).

Abstract
BACKGROUND The coronavirus disease 2019 (COVID-19) pandemic had adversely impacted cancer screening, diagnosis, and treatment. We investigated the change in medical resource, such as the intensive care unit use, and short-term outcomes after esophagectomy during the pandemic. METHODS Data of patients who underwent esophagectomy for esophageal cancer registered in the National Clinical Database (NCD) in Japan from January 2018 to December 2021 were analyzed. The time series change in the number of surgical cases; usage of intensive care unit; incidence of morbidity and mortality; standardized mortality and morbidity ratio (SMR) for 30-days mortality; surgical mortality; and morbidities for pneumonia, sepsis, unplanned intubation, and anastomotic leakage were evaluated. RESULTS The annual number of patients undergoing esophagectomy remained similar from 2018 to 2021. The negative impact of the pandemic on medical resources was strongly identified in the patients from an epidemic area where there is a higher cumulative number of infections per population as compared to all prefectures. The proportions of patients admitted to the intensive care unit were 91.4%, 93.0%, 91.6%, and 90.5% in 2018, 2019, 2020, and 2021, respectively. Moreover, 93.3%, 94.0%, 92.0%, and 90.9% patients who underwent surgery in an epidemic area were admitted to the intensive care unit in 2018, 2019, 2020, and 2021, respectively. However, the morbidity and mortality rates during the pandemic did not worsen according to the SMR values. CONCLUSIONS Esophagectomy was performed during the pandemic despite limited medical resources by a systematic endeavor of the entire surgical department in Japan, without increasing the incidence rate of worse outcome.

Enhancing Prediction for Tumor Pathologic Response to Neoadjuvant Immunochemotherapy in Locally Advanced Esophageal Cancer by Dynamic Parameters from Clinical Assessments. Cancers (Basel) 2023; 15:4377. [PMID: 37686655 PMCID: PMC10486879 DOI: 10.3390/cancers15174377] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/17/2023] [Revised: 08/25/2023] [Accepted: 08/30/2023] [Indexed: 09/10/2023] Open
Abstract
To develop accurate and accessible prediction methods for assessing pathologic response following NICT prior to surgery, we conducted a retrospective study including 137 patients with esophageal squamous cell carcinoma (ESCC) who underwent surgery after two cycles of NICT between January 2019 and March 2022 at our center. We collected clinical parameters to evaluate the dynamic changes in the primary tumor. Univariate and multivariate analyses were performed to determine the correlations between these parameters and the pathologic response of the primary tumor. Subsequently, we constructed prediction models for pCR and MPR using multivariate logistic regression. The MPR prediction Model 2 was internally validated using bootstrapping and externally validated using an independent cohort from our center. The univariate logistic analysis revealed significant differences in clinical parameters reflecting tumor regression among patients with varying pathologic responses. The clinical models based on these assessments demonstrated excellent predictive performance, with the training cohort achieving a C-index of 0.879 for pCR and 0.912 for MPR, while the testing cohort also achieved a C-index of 0.912 for MPR. Notably, the MPR prediction Model 2, with a threshold cut-off of 0.74, exhibited 92.7% specificity and greater than 70% sensitivity, indicating a low rate of underestimating residual tumors. In conclusion, our study demonstrated the high accuracy of clinical assessment-based models in pathologic response prediction, aiding in decision-making regarding organ preservation and radiotherapy adjustments after induction immunochemotherapy.

Abstract
Esophageal cancer has one of the poorest prognoses among all cancer types, due to the propensity for an early spread through the lymphatics and the difficulty to perform surgical treatment. To improve the prognosis, the management of esophageal cancer has been developed through the conduct of several clinical trials worldwide. In western societies, neoadjuvant chemoradiotherapy has been established as the standard treatment approach, as indicated by the results of the CROSS trial. Recently, the Japanese JCOG1109 trial demonstrated the significant improvement of survival by neoadjuvant triplet chemotherapy. As an adjuvant treatment, an immune checkpoint inhibitor has shown promising results in the CheckMate-577 trial. Including adjuvant S-1 mono therapy as another option, a randomised control phase III study will determine the ideal treatment for surgically resectable esophageal cancer. Furthermore, the efficacy and safety of neoadjuvant cisplatin +5-fluorouracil or DCF plus nivolumab are examined in the JCOG1804E (FRONTiER) study. In addition to definitive chemoradiation therapy, the SANO trial is examining the safety and efficacy of active surveillance after neoadjuvant chemoradiotherapy, which might give us the choice to adopt organ preservation approach. The development of treatment has progressed dramatically with the advent of immunotherapy. Considering the biomarkers to predict the treatment response and prognosis, individualised multidisciplinary treatment strategies should be established for esophageal cancer patients.

Toripalimab combined with definitive chemoradiotherapy in locally advanced oesophageal squamous cell carcinoma (EC-CRT-001): a single-arm, phase 2 trial. Lancet Oncol 2023; 24:371-382. [PMID: 36990609 DOI: 10.1016/s1470-2045(23)00060-8] [Citation(s) in RCA: 40] [Impact Index Per Article: 20.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/17/2022] [Revised: 01/27/2023] [Accepted: 02/02/2023] [Indexed: 03/29/2023]
Abstract
BACKGROUND Toripalimab is a PD-1 inhibitor that is approved for the treatment of advanced oesophageal squamous cell carcinoma, but its efficacy in locally advanced disease is unclear. We administered toripalimab with definitive chemoradiotherapy to patients with unresectable locally advanced oesophageal squamous cell carcinoma, and aimed to investigate the activity and safety of this regimen, and potential biomarkers. METHODS EC-CRT-001 was a single-arm, phase 2 trial done at Sun Yat-sen University Cancer Center (Guangzhou, China). Patients aged 18-70 years with untreated, unresectable, stage I-IVA oesophageal squamous cell carcinoma, with an ECOG performance status of 0-2, and adequate organ and bone marrow function were eligible for inclusion. Patients received concurrent thoracic radiotherapy (50·4 Gy in 28 fractions), chemotherapy (five cycles of weekly intravenous paclitaxel [50 mg/m2] and cisplatin [25 mg/m2]), and toripalimab (240 mg intravenously every 3 weeks for up to 1 year, or until disease progression or unacceptable toxicity). The primary endpoint was the complete response rate at 3 months after radiotherapy by investigator assessment. Secondary endpoints were overall survival, progression-free survival, duration of response, quality of life (not reported here), and safety. All enrolled patients were included in the activity and safety analyses. The trial is registered with ClinicalTrials.gov, NCT04005170; enrolment is completed and follow-up is ongoing. FINDINGS Between Nov 12, 2019, and Jan 25, 2021, 42 patients were enrolled. The median age was 56 years (IQR 53-63), 39 (93%) of 42 patients had stage III or IVA disease, and 32 (76%) patients were male and 10 (24%) were female. 40 (95%) of 42 patients completed the planned chemoradiotherapy and 26 (62%; 95% CI 46-76) of 42 had a complete response. The median duration of response was 12·1 months (95% CI 5·9-18·2). After a median follow-up of 14·9 months (IQR 11·9-18·4), 1-year overall survival was 78·4% (95% CI 66·9-92·0) and 1-year progression-free survival was 54·5% (41·3-72·0). The most common grade 3 or worse adverse event was lymphopenia (36 [86%] of 42). One (2%) patient died from treatment-related pneumonitis. INTERPRETATION Combining toripalimab with definitive chemoradiotherapy provided encouraging activity and acceptable toxicity in patients with locally advanced oesophageal squamous cell carcinoma, and this regimen warrants further investigation.

Abstract
The present study aimed to assess the feasibility of global standard chemoradiotherapy (CRT) followed by surgery in patients with esophageal cancer. A prospective study was conducted at Nagoya University Hospital (Nagoya, Japan) to evaluate global standard CRT followed by surgery in patients with esophageal cancer. The CRT regimen consisted of 75 mg/m2 cisplatin on day 1 and 1,000 mg/m2 fluorouracil daily on days 1-4 given twice 4 weeks apart together with concurrent esophageal irradiation starting on day 1 (group A). For comparison, 17 patients with esophageal cancer who had received the same chemotherapy regimen but with lower drug doses were retrospectively reviewed: 70 mg/m2 cisplatin on day 1 and 700 mg/m2 fluorouracil daily on days 1-4 given twice 4 weeks apart together with concurrent esophageal irradiation starting on day 1 (group B). Grade 3 or worse adverse events were observed in 9 of the 12 patients (75%) in group A and in 5 of the 17 patients (29%) in group B. The patients in group A were more likely to experience grade 3 or worse neutropenia (50%) than those in group B (6%). No febrile neutropenia or treatment-related deaths occurred in either group. A total of 11 patients (92%) in group A and 16 patients (94%) in group B subsequently underwent an esophagectomy, and 9 (82%) and 14 (88%) of these patients, respectively, achieved microscopically margin-negative resection (R0 resection). In conclusion, global standard CRT was more likely to cause severe but manageable adverse events. There was no apparent difference in the R0 resection rate or postoperative complications between the two treatments. This clinical trial was registered at the Japan Registry of Clinical Trials (trial registration number: jRCT1041180004) on September 11, 2018.

Abstract
BACKGROUND We previously reported that endoscopic response evaluation can preoperatively predict the prognosis and distribution of residual tumors after neoadjuvant chemotherapy (NAC). In this study, we developed artificial intelligence (AI)-guided endoscopic response evaluation using a deep neural network to discriminate endoscopic responders (ERs) in patients with esophageal squamous cell carcinoma (ESCC) after NAC. METHOD Surgically resectable ESCC patients who underwent esophagectomy following NAC were retrospectively analyzed in this study. Endoscopic images of the tumors were analyzed using a deep neural network. The model was validated with a test data set using 10 newly collected ERs and 10 newly collected non-ER images. The sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of the endoscopic response evaluation by AI and endoscopists were calculated and compared. RESULTS Of 193 patients, 40 (21%) were diagnosed as ERs. The median sensitivity, specificity, PPV, and NPV values for ER detection in 10 models were 60%, 100%, 100%, and 71%, respectively. Similarly, the median values by the endoscopist were 80%, 80%, 81%, and 81%, respectively. CONCLUSION This proof-of-concept study using a deep learning algorithm demonstrated that the constructed AI-guided endoscopic response evaluation after NAC could identify ER with high specificity and PPV. It would appropriately guide an individualized treatment strategy that includes an organ preservation approach in ESCC patients.

Abstract
Esophageal cancer is the seventh most common malignancy and sixth most common cause of cancer-related death globally. Esophageal squamous cell carcinoma (ESCC) with aortic or tracheal invasion is considered unresectable, and has an extremely poor prognosis; its standard treatment is definitive chemoradiotherapy (dCRT). In recent years, induction chemotherapy (ICT) has been reported to yield high response rates for locally advanced ESCC, and the efficacy and safety of ICT followed by conversion surgery (CS) have been investigated. Multimodal treatment, combining surgery with induction chemoradiotherapy (ICRT) or ICT, is necessary to improve ESCC prognosis. CS is generally performed for locally advanced ECC after ICRT or ICT when tumor downstaging is achieved, although its prognostic benefit remains controversial. The Japan Clinical Oncology Group (JCOG) has conducted a three-arm phase III randomized controlled trial (JCOG1510) to confirm the superiority of DCF (docetaxel, cisplatin, and 5-fluorouracil) ICT, over conventional dCRT, among patients with initially unresectable ESCC. In recent years, researchers have reported favorable outcomes of induction therapy followed by CS and salvage surgery, after dCRT or systemic immunochemotherapy. In this review, we will describe the latest developments in the multimodal treatment including chemotherapy, CRT, surgery, and immunotherapy, which may improve oncological and survival outcomes for patients with cT4 ESCC.
