Clinical trial: Study of Neo-adjuvant Chemoradiotherapy Followed by Minimally Invasive Esophagectomy for Squamous Cell Esophageal Cancer

Summary: The primary objective is to compare neo-adjuvant chemoradiotherapy followed by Mckeown Minimally Invasive Esophagectomy (MIE) Versus Mckeown MIE, pure radical chemoradiotherapy in terms of the overall survival time (OS) in patients with Stage IIB or III squamous cell esophageal carcinoma.

Detailed description: Esophageal cancer is one of the most difficult malignancies to cure. Surgical resection remains the primary treatment for localized esophageal cancer. It increases the chances of cure and alleviates the symptoms of dysphagia compared with nonoperative methods. Advances in surgical techniques and equipments have made minimally invasive esophagectomy (MIE) more popular and wider application since 1990s. During the past two decades, MIE has progressively been accepted as an alternative treatment for esophageal cancer around the world. The prognosis has some improvement on account of these significant advances in surgical techniques and perioperative management, But the prognosis of patients with locally advanced esophageal cancer remains rather poor. As a result of surgery alone, the 5-year survival rate of about 25% has not changed significantly in several decades.
  Preoperative chemoradiotherapy followed by surgery seems to hopefully improve the survival of EC. Nevertheless, the results of different studies were inconsistent. Recently, the CROSS trial has demonstrated that preoperative chemoradiotherapy can significantly increased the overall survival of patients with EC compared with surgery alone. It should be noticed that only 84 cases(23%) of ESCC were enrolled in this trial with potential minimal follow-up of 2 years, which may be not perfect to evaluate the effect of this combined therapy for this tumor type.
  Based on our preliminary study, we have demonstrated the validity and safety of vinorelbine and cisplatin-based neoadjuvant chemoradiotherapy. Then we are to carry out a clinical trial to investigate the effect of this multidisciplinary therapy, by comparing neo-adjuvant chemoradiotherapy followed by Mckeown MIE versus Mckeown MIE, pure radical chemoradiotherapy in terms of the overall survival time (OS) in patients with Stage IIB or III squamous cell esophageal carcinoma.

Eligibility: Inclusion Criteria:
  1. Histologic diagnosis of squamous cell thoracic esophageal carcinoma of Stage IIB or III, which is potentially resectable.
  2. Patients must not have received any prior anticancer therapy.
  3. More than 6 months of expected survival.
  4. Age ranges from 18 to 70 years.
  5. Absolute white blood cells count ≥4.0×109/L, neutrophil ≥1.5×109/L, platelets ≥100.0×109/L, hemoglobin ≥90g/L, and normal functions of liver and kidney.
  6. Karnofsky performance status (KPS) of 90 or more.
  7. Signed informed consent document on file.
  Exclusion Criteria:
  1. Patients are diagnosed or suspected to be allergic to cisplatin or vinorelbine.
  2. Patients with concomitant hemorrhagic disease.
  3. Pregnant or breast feeding.
  4. Inability to use gastric conduit after esophagectomy because of a prior surgery.
  5. Patients with concomitant peripheral neuropathy, whose CTC status is 2 or even more.
  6. Have a prior malignancy other than esophageal carcinoma, carcinoma in situ of the cervix, nonmelanoma skin cancer or cured early stage of prostate cancer.
