Neoadjuvant therapy or upfront surgery? A systematic review and meta-analysis of T2N0 esophageal cancer treatment options

BACKGROUND

Esophageal carcinoma usually shows poor long-term survival rates, even when esophagectomy, the standard curative treatment is performed. As a result, there has been increasing interest in the neoadjuvant therapy, which could potentially downstage cancer, eliminate micrometastasis and ergo increase resectability and curative (R0) resection. Currently, for the earliest stage esophageal cancers, most guidelines point out to the role of endoscopic treatment, and for T1bN0 upfront surgery. For locally advanced cases, several studies have demonstrated the benefits of neoadjuvant therapy to increase resectability. For clinical stage T2N0 esophageal cancer, there is no consensus as to the optimal treatment strategy.

METHODS

A systematic review and meta-analysis was performed to compare neoadjuvant therapy with surgery alone on clinical stage T2N0 esophageal cancer patients, concerning overall survival, recurrence, post-operative mortality, anastomotic leak, and R0 resection rate.

RESULTS

For overall survival at the mean follow-up point, the neoadjuvant therapy was not associated to a higher probability of survival than upfront surgery in cT2N0 patients (risk difference: 0.00; 95% CI: -0.09, 0.09). There was no difference between neoadjuvant therapy and primary surgery concerning recurrence (risk difference: 0.21; 95% CI: -0.03, 0.45); perioperative mortality (risk difference: 0.00; 95% CI: -0.02, 0.01); and risk for anastomotic leak (risk difference: -0.08; 95% CI: -0.21, 0.05). Pooled data showed that neoadjuvant therapy was associated to a higher risk for positive margins after resection (risk difference: 0.04; 95% CI: 0.02, 0.06).

CONCLUSIONS

This review showed that neoadjuvant therapy is not associated to better results than surgery alone, for the management of clinical stage T2N0 esophageal cancer patients, concerning overall survival, recurrence rate, perioperative mortality, anastomotic leak, and seems to be associated to a higher risk for resection with positive margins.

Multidisciplinary management of esophageal cancer

This article reviews the current management of esophageal cancer, including staging and treatment options, as well as providing support for using multidisciplinary teams to better manage esophageal cancer patients.

Thoracic surgery in octogenarians: CVTSA/Inova Fairfax hospital experience, 1990 to 2009

With an increasing proportion of U.S. individuals 80 years of age or older, the authors examined their surgical experience with octogenarians undergoing major, curative-intent thoracic surgery. Between January 1, 1990, and September 1, 2009, 102 octogenarians underwent curative-intent resection for nonsmall cell carcinoma of the lung (NSCCL), esophageal carcinoma (EC), or related surgery for thoracic esophageal perforation (EP). Analysis and reporting followed the guidelines of the Nationwide Inpatient Sample database study (1994 to 2003). Eighty-six patients underwent curative-intent resection for NSCCL, 12 for EC, and four for surgery for EP. Hospital and 30-day mortalities were 0 per cent. Overall 1-, 2-, and 5-year survival rates were: 78, 58, and 32 per cent. Within the NSCCL cohort, minimally invasive exposures (video-assisted thoracic surgery [VATS] and video thoracoscopy [VT]) were associated with fewer and shorter duration of air leaks, leading to shorter length of stay. Since we began using minimally invasive exposure for NSCCL in 2007, the percentage of octogenarians discharged within 5 days of surgery has increased from 35.5 to 66.7 per cent (P = 0.01), and the percentage of patients discharged within 3 days of surgery has increased from 8.1 to 33.3 per cent (P = 0.006). Of 24 patients undergoing surgery for NSCCL since 2007, 18 (75%) underwent minimally invasive (VATS or VT) exposures, of which 15 patients (83.3%) were discharged home within 5 days and eight (44.4%) within 3 days of their procedure. Excellent, short- and longer-term results can be achieved in elderly patients if risks, exposures, and resections are appropriately matched to patient performance.
