Brief Summary

To date, there is controversy as to whether type II diabetes mellitus is associated with adverse short- and long-term outcomes in patients with esophageal squamous cell carcinoma undergoing minimally invasive esophagectomy. At the same time, to the best of our knowledge, the impact of metformin use and glycemic control on short- and long-term outcomes in this patient population is also controversial. Therefore, this study aims to test the hypothesis that diabetes mellitus is associated with reduced survival in patients with esophageal squamous cell carcinoma undergoing minimally invasive esophagectomy and that treatment with metformin and/or good glycemic control (HbA1c\<7.0%) is associated with improved survival.

Outcome Measures

Primary Outcomes (2)

  • Overall survival

    Overall survival (OS) was defined as the time from the date of surgery to death from any cause or last follow-up.

    About five years postoperatively

  • Disease-free survival

    Disease-free survival (DFS) was defined as the time from the date of surgery to recurrence, metastasis, and death from any cause.

    About five years postoperatively

Secondary Outcomes (2)

  • postoperative adverse events

    within 90 days postoperatively

  • perioperative 90-day mortality

    within 90 days postoperatively

Study Arms (2)

Coe-T2DM group

There was a definitive diagnosis of type 2 diabetes mellitus before surgery

Other: Whether there is type 2 diabetes mellitus before surgery

No-T2DM group

There was no clear diagnosis of type 2 diabetes mellitus before surgery

Interventions

Patients were grouped according to whether they had type 2 diabetes mellitus before surgery

Coe-T2DM group

Study Population

Patients with EC who attended the Department of Thoracic Surgery at Daping Hospital and underwent the McKeown MIE procedure performed by the same surgical team were included for evaluation from September 2017 to September 2021.

You may qualify if:

  • Patients with a clear pathologic diagnosis of esophageal squamous cell carcinoma;
  • Received minimally invasive McKeown procedure;
  • Patients with R0 resection (R0: radical resection).

You may not qualify if:

  • Concomitant history of other primary cancers or other cancers;
  • Distant metastases before surgery;
  • Serious comorbidities of other systems before surgery;
  • Patients diagnosed with T2DM during follow-up;
  • The medical record information is incomplete.
