Endoscopic Resection

EMR (endoscopic mucosal resection) or ESD (endoscopic submucosal dissection) or ablation (e.g. RFA or radiofrequency ablation or cryoablation or photodynamic therapy)

Goal is the complete removal and eradication of all cancer in early stage disease (Tis or T1a)

One of the largest studies with long-term follow-up included 402 patients with superficial esophageal squamous carcinoma

The patients were treated either with EMR (48 percent) or ESD (52 percent) The overall survival rates was 84 percent.

Survival was highest among patients whose tumors did not invade beyond the lamina propria (five-year survival rate of 91 percent).

The five-year survival rate was 71 percent both for patients with involvement of the muscularis mucosa and for patients with involvement of the submucosa.

Am J Gastroenterol. 2013;108(4):544.

EMR or ESD• A meta-analysis of 15 studies found that ESD,

compared with EMR, had higher en bloc and curative resection rates as well as lower rates of local recurrence for malignant and premalignant lesions of the gastrointestinal tract. Similar results were noted in two other meta-analyses

• In a retrospective study of 300 patients with squamous cell cancer of the esophagus, patients who underwent resection with ESD had significantly higher en bloc resection rates and lower local recurrence rates compared with patients who underwent EMR (100 versus 53 percent and 1 versus 10 percent, respectively)

Chemoradiation

.A meta-analysis of randomized controlled trials that compared neoadjuvant chemoradiation and surgery to surgery alone for resectable esophageal cancer.Urschel JD, Vasan H Am J Surg.2003 Jun;185(6):538-43

Compared with surgery alone, neoadjuvant chemoradiation and surgery improved 3-year survival and reduced local-regional cancer recurrence.

Preoperative chemoradiotherapy for oesophageal cancer: a systematic review and meta-analysis.Gut.2004 Jul;53(7):925-30.

In patients with resectable oesophageal cancer, chemoradiotherapy plus surgery significantly reduces three year mortality (OR = 0.53) compared with surgery alone. However, postoperative mortality was significantly increased (OR = 2.10) by neoadjuvant chemoradiotherapy.

Survival after neoadjuvant chemotherapy or chemoradiotherapy for resectable oesophageal carcinoma: an updated meta-analysis.Lancet Oncol.2011 Jul;12(7):681-92.

The HR for all-cause mortality for neoadjuvant chemoradiotherapy was 0.78. The HR for the overall indirect comparison of all-cause mortality for neoadjuvant chemoradiotherapy versus neoadjuvant chemotherapy was 0.88.

This updated meta-analysis provides strong evidence for a survival benefit of neoadjuvant chemoradiotherapy or chemotherapy over surgery alone in patients with oesophageal carcinoma

157 esophageal cancer patients at the University of Texas M.D. Anderson Cancer Center The treatment approaches included preoperative chemotherapy, n = 76 or preoperative C/RT, n = 81

Preoperative C/RT demonstrated increased pathologic complete response (28% versus 4%) and overall survival (3 years, 48% versus 29%)

Principles of Surgery

All patients who are fit enough to undergo major resection (esophagectomy) should be considered for surgery unless:

Tumor is < 5cm from the cricopharyngeus (too high in the neck)

Superficial (Tis or Ta) enough that endoscopic surgery would be an option

Too locally advanced (inoperable or bulky lymph nodes or metastatic)
