Lymphovascular Invasion as the Major Prognostic Factor in Node-Negative Esophageal Cancer After Primary Esophagectomy

AbstractBackgroundStudies addressing both lymphovascular invasion (LVI) and perineural invasion (PNI) in patients with esophageal squamous cell carcinoma (ESCC) treated with or without neoadjuvant therapy are limited. We aimed to analyze the incidence and prognostic significance of LVI and PNI in patients with thoracic ESCC.MethodsThis retrospective study included 520 patients with ESCC: 174 patients after neoadjuvant treatment followed by surgery and 346 after primary esophagectomy, from two medical centers. The relationships between LVI, PNI, and other histological factors were evaluated. The Cox regression model was used for survival analysis.ResultsPositive LVI and PNI were noted in 35.6% and 22.4% of patients with residual primary tumor after neoadjuvant treatment and in 39.6% and 24.0% of patients who underwent primary esophagectomy, respectively. In patients with neoadjuvant treatments, the 5-year overall survival rates were 12.7% and 28.3% in patients with positive LVI and negative LVI, respectively (p = 0.001). The 5-year overall survival rates were 6.4% and 29.9% in patients with positive PNI and negative PNI, respectively (p

Authors: Chen Y, Wu X, Hao D, Cheng X, Zhang L, Zhang Y, Ke S, Shi W, He C Abstract Neoadjuvant therapy improves long-term locoregional control and overall survival after surgical resection for esophageal cancer, and neoadjuvant chemotherapy (nCT) or neoadjuvant chemoradiotherapy (nCRT) are commonly used in clinical practice. Nimotuzumab is a humanized monoclonal antibody against epidermal growth factor receptor (EGFR), the efficacy of nimotuzumab added to nCRT for esophageal cancer is uncertain. We conducted this retrospective study in which combining neoadjuvant treatment of nimotuzumab with chemoradiotherapy (Ni...

There is no consensus about the combined therapeutic strategy for esophageal squamous cell carcinoma in China. The quality control and standardization of surgery procedures were far from satisfactory in past neoadjuvant chemotherapy trials, which may underestimate the survival benefits. Therefore, we tried to evaluate the survival benefit of paclitaxel plus platinum followed by minimally invasive esophagectomy with total two-field lymphadenectomy patterns versus primary surgery. Between 06/2011 and 12/2014, there were 279 consecutive patients who underwent minimally invasive esophagectomy with total two-field lymphadenecto...

Conclusions: To cover 94.5% of ESCC subclinical lesions in the CTVp, a 3-cm margin along the cranial-caudal axis should be added to the primary gross tumor volume as defined by FDG-PET/CT, as well as a cutoff SUVmax value of 2.5. Although preoperative FDG PET/CT images may not reveal lesions directly, the SUVmax and MTV measurements together could predict their presence. Background Esophageal carcinoma often occurs as squamous cell carcinoma (ESCC), a highly aggressive malignancy with a poor prognosis worldwide. The incidence rates of ESCC are particularly high in China (1). Most patients with ESCC have locally adv...

AbstractBackgroundPostoperative complications have a negative impact on overall survival after esophagectomy because systemic inflammation may induce residual cancer cell growth. A solution that could suppress micrometastasis is neoadjuvant therapy; however, to date, no study has shown that neoadjuvant therapy suppresses proliferation of cancer cells due to postoperative complications after esophagectomy. The aim of this study is to investigate the influence of neoadjuvant therapy on poor long-term outcomes of postoperative complications in patients with esophageal carcinoma.Patients and MethodsIn total, 431 patients who u...

Objective: To determine the impact of histology on pathologic response, survival outcomes, and recurrence patterns in patients with esophageal cancer (EC) who received neoadjuvant chemoradiotherapy (CRT). Summary of Background Data: There is a paucity of data regarding comparative outcomes after neoadjuvant CRT between esophageal squamous cell carcinoma (SCC) and adenocarcinoma. Methods: Between 2002 and 2015, 895 EC patients who underwent neoadjuvant CRT followed by esophagectomy at 3 academic institutions were retrospectively reviewed, including 207 patients with SCC (23.1%) and 688 patients with adenocarcinoma (...
