Preoperative camrelizumab combined with chemotherapy for borderline resectable ESCC: A single-arm, prospective, phase 2 study. MED 2024:S2666-6340(24)00297-6. [PMID: 39121854 DOI: 10.1016/j.medj.2024.07.015] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/01/2024] [Revised: 03/25/2024] [Accepted: 07/15/2024] [Indexed: 08/12/2024]
Abstract
BACKGROUND We investigated the safety and efficacy of preoperative camrelizumab combined with chemotherapy for treating thoracic borderline resectable esophageal squamous cell carcinoma (Br-ESCC) (ChiCTR2200056728). METHODS Patients with thoracic Br-ESCC received intravenous camrelizumab plus chemotherapy and underwent esophagectomy. The primary endpoint was the pathologic complete response (pCR) rate. We introduced computed tomography and endoscopic examination into the diagnostic criteria to increase its reproducibility. Additionally, we defined a new resection status, Rbr+/-, for Br-ESCC. FINDINGS Thirty-one patients with Br-ESCC were ultimately enrolled in this study. Overall, 71.0% (22/31) of the patients underwent esophagectomy. R0 resection was achieved in 81.8% of patients (18/22). pCR and major pathological response were observed in 40.9% (9/22) and 63.6% (14/22) of the resected patients, respectively. Eighteen R0 resection patients were redefined according to our Rbr definition; 61.1% (11/18) were classified as Rbr+ resection, and 38.9% (7/18) were classified as Rbr- resection. With a median postoperative follow-up of 17.9 months, 4 patients out of 11 who underwent Rbr+ resection experienced local recurrence (2 of whom achieved pCR). However, no patients (0/7) who underwent Rbr- resection experienced local recurrence. CONCLUSIONS Esophagectomy after neoadjuvant immunochemotherapy is a promising radical treatment for Br-ESCC. R0 resection was achieved in 81.8% of patients, and a pCR was observed in 40.9% of resected patients. Even after complete excision, Rbr+ resection leads to a higher rate of local recurrence in patients with Br-ESCC. FUNDING This study was supported by the Key Scientific Research Projects of the Institutions of Higher Learning in Henan Province (no. 21A320032).

Prognostic significance of positive lymph node regression grade to neoadjuvant chemoradiation for esophageal squamous cell carcinoma. J Surg Oncol 2024; 129:708-717. [PMID: 38124398 DOI: 10.1002/jso.27555] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/10/2023] [Revised: 10/25/2023] [Accepted: 11/26/2023] [Indexed: 12/23/2023]
Abstract
BACKGROUND AND PURPOSE To assess the relationship between metastatic lymph node (LN) responder status and recurrence-free survival (RFS) in patients undergoing neoadjuvant chemoradiotherapy (NCRT). MATERIALS AND METHODS We retrospectively reviewed 304 patients with local advanced esophageal squamous cell carcinoma received NCRT followed by esophagectomy. For 112 patients with positive node, according to the proportion of residual viable tumor cells area within the whole tumor beds of all metastatic LNs, we classified LN-tumor regression grade (LN-TRG) into four categories: grade 1, 0%; 2, <10%; 3, 10%-50%; 4, >50%. Patients with grade 1-2 LN-TRG of were considered LN responders, and those with grades 3-4, as LN nonresponders. Univariate and multivariate analyses of RFS were estimated by a Cox regression model, Kaplan-Meier curve, and log-rank test. RESULTS The median follow-up time of a total of 112 patients was 29.6 months. Fifty-two (46.4%) patients have experienced recurrence. In Cox univariate analysis, differentiation, AJCC stage LN responder status, nerve invasion, and lymphovascular invasion significantly correlated with RFS. Multivariate analysis for RFS revealed that LN responder status and AJCC stage (p < 0.05) were independent prognostic factor. The 3-year RFS rates for patients with LN-TRG of 1-4 grades were 72.7%, 76.5%, 37.4%, and 28.5%, respectively, and the median RFS times were not reach, 43.56, 28.09, and 22.77, respectively. CONCLUSIONS LN responder status is an independent prognostic factor for RFS in esophageal cancer patients who received NCRT.

Development and Validation of a Recurrence-Free Survival Prediction Model for Locally Advanced Esophageal Squamous Cell Carcinoma with Neoadjuvant Chemoradiotherapy. Ann Surg Oncol 2024; 31:178-191. [PMID: 37751117 PMCID: PMC10695895 DOI: 10.1245/s10434-023-14308-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/27/2023] [Accepted: 08/30/2023] [Indexed: 09/27/2023]
Abstract
BACKGROUND A recurrence-free survival (RFS) prediction model was developed and validated for patients with locally advanced esophageal squamous cell carcinoma treated with neoadjuvant chemoradiotherapy (NCRT) in combination with surgery. PATIENTS AND METHODS We included 282 patients with esophageal squamous cell carcinoma who received neoadjuvant chemoradiotherapy (NCRT) combined with surgery, constructed three models incorporating pathological factors, investigated the discrimination and calibration of each model, and compared the clinical utility of each model using the net reclassification index (NRI) and the integrated discrimination index (IDI). RESULTS Multivariable analysis showed that pathologic complete response (pCR) and lymph node tumor regression grading (LN-TRG) (p < 0.05) were independent prognostic factors for RFS. LASSO regression screened six correlates of LN-TRG, vascular invasion, nerve invasion, degree of differentiation, platelet grade, and a total diameter of residual cancer in lymph nodes to build model three, which was consistent in terms of efficacy in the training set and validation set. Kaplan-Meier (K-M) curves showed that all three models were able to distinguish well between high- and low-risk groups (p < 0.01). The NRI and IDI showed that the clinical utility of model 2 was slightly better than that of model 1 (p > 0.05), and model 3 was significantly better than that of model 2 (p < 0.05). CONCLUSIONS Clinical prediction models incorporating LN-TRG factors have high predictive efficacy, can help identify patients at high risk of recurrence after neoadjuvant therapy, and can be used as a supplement to the AJCC/TNM staging system while offering a scientific rationale for early postoperative intervention.

Therapeutic strategy aiming at R0 resection for borderline-resectable esophageal squamous cell carcinoma using induction chemotherapy with docetaxel, cisplatin, and 5-fluorouracil. Gen Thorac Cardiovasc Surg 2023; 71:584-590.

Abstract
OBJECTIVE Treatment for borderline resectable (cT3br) esophageal squamous cell carcinoma (SCC) is currently undefined. This study aimed to analyze the outcome of treatment strategies including induction chemotherapy with docetaxel, cisplatin, and 5-fluorouracil (DCF) against T3br esophageal SCC. METHODS A total of 32 patients with cT3br esophageal SCC enrolled in this study were treated with two cycles of DCF induction therapy. RESULTS The overall response rate to DCF induction therapy was 62.5%, while the disease control rate was 93.8% (complete response (CR), three; partial response (PR), 17; stable disease (SD), 10; progressive disease (PD), 2). After DCF induction chemotherapy, 27 patients underwent conversion surgery (CS) and five patients underwent definitive chemoradiotherapy (CRT). Out of 27 patients who underwent CS, 17 underwent transthoracic esophagectomy and 10 underwent thoracoscopic esophagectomy. Anastomotic leakage occurred in five patients (18.5%) and pneumonia in four (14.8%). Recurrent laryngeal nerve paralysis and arrhythmia were observed in two patients (7.4%). The R0 resection rate was 81.5%. Among the five patients who underwent definitive CRT, only one patient (20.0%) achieved CR. Two patients (40.0%) had PR and two (40.0%) had PD. Salvage esophagectomy was performed in one patient after definitive CRT. The 1-, 3-, and 5-year overall survival rates were 75.0, 50.6, and 46.4%, respectively, whereas the 1-, 3-, and 5-year disease-free survival rates were 54.9, 38.8, and 38.8%, respectively. CONCLUSION DCF induction therapy and subsequent CS or definitive CRT are promising treatment strategies for cT3br esophageal SCC.
