Early Contrast-Enhanced MR for Diagnosing Complete Tumor Response of Locally Advanced Esophageal Squamous Cell Carcinoma After Neoadjuvant Therapy: A Retrospective Comparative Study. Ann Surg Oncol 2024; 31:4271-4280. [PMID: 38453768 DOI: 10.1245/s10434-024-15123-0] [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: 12/27/2023] [Accepted: 02/14/2024] [Indexed: 03/09/2024]
Abstract
BACKGROUND This study assessed the performance of early contrast-enhanced magnetic resonance (ECE-MR) in the detecting of complete tumor response (ypT0) in patients with esophageal squamous cell carcinoma following neoadjuvant therapy. PATIENTS AND METHODS Preoperative MR images of consecutive patients who underwent neoadjuvant therapy and surgical resection were reviewed retrospectively. The accuracy of ECE-MR and T2WI+DWI was evaluated by comparing the findings with pathological results. Receiver operating characteristic curve analysis was used to assess the diagnostic performance, and DeLong method was applied to compare the areas under the curves (AUC). Chi-squared analysis was conducted to explore the difference in pathological changes. RESULTS A total of 198 patients (mean age 62.6 ± 7.8 years, 166 men) with 201 lesions were included. The AUC of ECE-MR was 0.85 (95% CI 0.79-0.90) for diagnosing ypT1-4, which was significantly higher than that of T2WI+DWI (AUC 0.69, 95% CI 0.63-0.76, p < 0.001). The diagnostic performance of both T2WI+DWI and ECE-MR improved with increasing tumor stage. The AUCs of ECE-MRI were higher in ypT1 and ypT2 tumors than T2WI+DWI. Degree 2-3 tumor-infiltrating lymphocytes and neutrophils were commonly seen in ypT0 tumors misdiagnosed by ECE-MR. CONCLUSIONS Visual evaluation of ECE-MR is a promising diagnostic protocol for the detection of complete tumor response, especially for differentiation with early stage tumors. The accurate diagnosis of complete tumor response after neoadjuvant therapy using imaging modalities is of important significance for clinical decision-making for patients with esophageal squamous cell carcinoma. It is hoped that early contrast-enhanced MR will provide supportive advice for the development of individualized treatment options for patients.

Abstract
Compared with postoperative adjuvant therapy, neoadjuvant therapy has more potential advantages, such as decreasing tumor stage, killing micrometastatic cells. Because of these advantages, neoadjuvant therapy is recommended for numerous types of tumor, such as breast, lung and rectal cancer. To determine the role of neoadjuvant therapy on overall survival and adverse for patients with resectable esophageal carcinoma. we summarized clinical studies on 7 types of neoadjuvant therapies in this review. Currently, patients with esophageal cancer (EC) in China mainly receive postoperative treatment with <30% of patients receiving neoadjuvant therapy. One reason for the limited use of neoadjuvant therapy in China is inaccurate staging based on imaging and neoadjuvant treatment may increase difficulties in surgery. After neoadjuvant therapy, there may be tissue edema, blurry surgical field of view and unclear tissue gaps, resulting in greater difficulty in surgical procedures. However, oncologists are interested in neoadjuvant treatment, especially neoadjuvant immunotherapy to treat EC. Concurrent chemoradiotherapy for esophageal squamous cell carcinoma (ESCC) is the most common neoadjuvant treatment regimen and increases the pathological complete response (pCR) and 5- and 10-year survival rates. Preoperative induction chemotherapy and sequential concurrent chemoradiotherapy are currently the most widely treatments used in clinical practice in China. However, this treatment strategy does not yield long-term survival. The pCR rate of neoadjuvant immunotherapy is greater than that of concurrent chemoradiotherapy but, to the best of our knowledge, no evidence of long-term survival benefit has been found in phase I and II clinical trials. Neoadjuvant treatment should be considered for patients with locally advanced ESCC.

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.
