Brief Summary

Esophageal carcinoma is an aggressive malignant disease with poor prognosis. Surgical resection remains the most effective method for this malignancy. Although different approaches have been studied for the surgical resection of thoracic esophageal cancer, little evidence has been achieved due to lack of large scale multicenter randomized trials with regard to this issue: whether left transthoracic approach or right transthoracic approach is the optimal surgical approach for treating middle and lower thoracic esophageal cancer without upper mediastinal lymph node metastasis. The purpose of this study is to compare the postoperative local recurrence rate and long-term outcome of esophagectomy through left and right transthoracic approach in the middle and lower thoracic esophageal cancer patients without preoperative upper mediastinal lymph node metastasis.

Study Arms (2)

Left thoracotomy

ACTIVE COMPARATOR

Esophagectomy through left side transthoracic approach, with esophagogastric anastomosis above aortic arch and two-field lymphadenectomy (thoracic and abdominal lymph node)

Procedure: Left thoracotomy

Right thoracotomy

ACTIVE COMPARATOR

Esophagectomy through right side transthoracic approach, with esophagogastric anastomosis above azygos vain arch or on the top of chest cavity and two-field lymphadenectomy (thoracic and abdominal lymph node)

Procedure: Right thoracotomy

Interventions

Transthoracic approach is the surgical procedure including the open and minimally invasive thoracotomy.

Left thoracotomy

Transthoracic approach is the surgical procedure including the open and minimally invasive thoracotomy.

Eligibility Criteria

Age18 Years - 75 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Patients with histologically proved squamous cell esophageal cancer without any previous anti-tumor therapy;
  • The preoperative clinical TNM stage: cT1b-3N0-1M0;
  • Adequate function of heart, lung, liver, brain and kidney, which can tolerate esophagectomy either through left or right thoracotomy;
  • Without any preoperative distant metastases confirmed by preoperative examination such as chest and abdominal CT, brain MRI and bone scan or PET-CT;
  • No evidence showing suspicious upper mediastinal lymph node metastasis (short diameter of LN \<0.8cm or shortest diameter / longest diameter \<0.65) by the thoracic and abdominal CT and endoscopic ultrasonography(EUS).
  • Willing to participate the clinical trial and sign informed consent before being enrolled into clinical trail.

You may not qualify if:

  • Non-squamous cell esophageal carcinoma or has any previous anti-cancer therapy before surgery;
  • The preoperative clinical TNM stage reaches: N2-3 or M1;
  • Inadequate cardiopulmonary, liver, brain and kidney function for tolerating the esophagectomy ;
  • Previous history of malignancy;
  • Unwilling to participate the clinical trial and refuse to sign informed consent
