Comparative Study
Peroral endoscopic myotomy versus surgical myotomy for primary achalasia: single-center, retrospective analysis of 74 patients.
Achalasia is a neurodegenerative motility disorder of the esophagus; dysphagia, weight loss, chest pain, and regurgitation are its main symptoms. Surgical myotomy (HM) is considered the gold standard treatment. However, peroral endoscopic myotomy (POEM) seems to be a safe and effective alternative option. ⋯ Perioperative results for POEM and SM are similar. The absence of an antireflux wrap leads to an increased risk of reflux with consequent esophagitis. SM with an antireflux wrap could be a preferred choice when a long standing gastroesophageal reflux could potentially lead to a damage as, for example, in young patients.

We retrospectively reviewed 102 patients with esophageal cancer (97.1% squamous cell carcinoma, 96.1% stage III) received FDG-PET staging and were treated by chemoradiotherapy with or without resection to assess whether the pretreatment [18F]fluorodeoxyglucose positron emission tomography (FDG-PET) maximum standardized uptake value (SUVmax) of the primary tumor and metastatic lymph nodes can predict the prognosis of patients with esophageal cancer. Receiver operating characteristic analysis was performed to find the cutoff values for primary tumor SUVmax and nodal SUVmax. The influence of clinical factors including primary tumor SUVmax and nodal SUVmax on local progression-free survival, nodal progression-free survival (NPFS), distant metastases-free survival (DMFS), and overall survival (OS) were evaluated using univariate and multivariate analyses. ⋯ High nodal SUVmax (≥7) predicted for worse outcomes than low nodal SUVmax (<7) in the patients who received dCRT (two-year DMFS, 17% vs. 92%, P < 0.001; NPFS, 14% vs. 81%, P = 0.001; OS, 21% vs. 50%, P = 0.003), but not in those received trimodality. On multivariate analysis of patients receiving dCRT, nodal SUVmax was the strongest independent predictor on DMFS (hazard ratio [HR] 13.93, P < 0.001), NPFS (HR 3.99, P = 0.026), PFS (HR 2.90, P = 0.003), and OS (HR 3.80, P = 0.001). High pretreatment nodal SUVmax predicts worse treatment outcomes for the patients treated with dCRT.

Trimodal therapy consisting of neoadjuvant chemoradiation followed by esophagectomy has become the standard of care in North America for locally advanced esophageal cancer. While cisplatin/5-fluorouracil has been a common concurrent chemotherapy regimen since the 1980s, its utilization has declined in recent years as the Chemoradiotherapy for Oesophageal Cancer Followed by Surgery Study (CROSS) trial regimen of carboplatin/paclitaxel has become widely adopted. The efficacy of the CROSS regimen compared to alternate chemotherapy choices, however, has rarely been evaluated when each is used as a component of a trimodal treatment approach. ⋯ Multivariable analysis demonstrated that the cisplatin/5-fluorouracil.group had an increased odds of pathologic complete response (odds ratio = 2.68, 95% confidence interval, P = 0.032), as well as significantly improved recurrence-free survival (hazard ratio = 0.39, 95% confidence interval 0.21-0.73, P = 0.003) and overall survival (hazard ratio = 0.46, 95% confidence interval 0.24-0.87, P = 0.016), compared to the carboplatin/paclitaxel group. Concurrent chemotherapy with cisplatin/5-fluorouracil in locally advanced esophageal cancer is associated with higher rates of pathologic complete response and improved recurrence-free and overall survival compared to the CROSS regimen of carboplatin/paclitaxel. This suggests that, for select patients, alternate neoadjuvant chemotherapy approaches, such as cisplatin/5-fluorouracil, merit reconsideration as potential primary treatment choices in the management of this highly morbid disease.

Esophageal cancer is the eighth most common cancer worldwide. It is the fourth most common cause of cancer death in China and esophageal squamous cell carcinoma (ESCC) is the most prevalent histologic type. Many clinical trials have explored the value of neoadjuvant or adjuvant chemoradiation therapy in potentially resectable ESCC; however, these studies have produced conflicting results. ⋯ Among lymph node-positive patients, the median survival times and 5-year OS rates for the neoadjuvant and adjuvant groups were 55.6 versus 23.7 months, and 43.0% versus 25.7%, respectively (P = 0.085). The incidence of perioperative and postoperative complications was comparable between the two groups (P > 0.05). For patients with resectable stage II/III ESCC, neoadjuvant chemoradiation does not increase postoperative complications and is associated with a trend toward better OS when compared to adjuvant chemoradiation.

Comparative Study
A retrospective comparison of neoadjuvant chemoradiotherapy regimens for locally advanced esophageal cancer.
Preoperative chemoradiotherapy (CRT) with carboplatin/paclitaxel has been shown to increase survival in patients with esophageal cancer, including gastroesophageal junction (GE) junction cancer, over surgery alone; however, there have been no studies comparing the different neoadjuvant CRT regimens. We retrospectively evaluated the long-term results of trimodality therapy for patients with locally advanced esophageal cancer treated on several chemotherapy regimens. Between 1999 and 2014, 215 patients with locally advanced esophageal cancer underwent neoadjuvant CRT followed by surgical resection. The median age was 62 years (range 21-84), 80.5% were men and 86% had adenocarcinoma. ⋯ Forty-four patients (20.5%) required readmission within 30 days of discharge, and readmission was associated with cardiac comorbidity (OR 2.7, P = 0.017). Three patients died within 30 days of surgery. We observed an association between neoadjuvant carboplatin/paclitaxel and improved overall survival that requires confirmation in a prospective randomized trial.
