[Simultaneous Surgical Treatment of Non-small Cell Lung Cancer and Off-pump Coronary Artery bypass Grafting.].

BACKGROUND

Patients with resectable lung cancer and unstable coronary heart disease are at high risks of postoperative death or severe cardioovascular complications. They always pose a therapeutic challenge for thoracic surgeons. The aim of this study is to summarize clinical experience of radical lung resection for cancer with simultaneous off-pump coronary artery bypass grafting.

METHODS

Seven patients who suffered from non small cell lung cancer concomitant arrhythmia, unstable angina and recent history of myocardial infarction had been carried out simultaneous radical lobectomy and off-pump coronary artery bypass grafting. Preoperative 6 patients had been confirmed to be misfit for either coronary arterioplasty or stent implanting by performing the coronary angiography. One patient had undergone stenting before the lung cancer had been diagnosed. The procedure through median sternotomy performed offpump coronary artery bypass grafting preceded lobectomy and mediastinal lymphadenectomy. Left upper lobectomy was performed in 2 patients, right upper lobectomy was performed in 1 patient, right upper and middle lobectomy was performed in one patient, video thoracoscopy assisted left lower lobectomy was performed in 1 patient, right lower lobectomy was performed in 2 patients.

RESULTS

There was no death of patient in hospital, however, a patient died 7th month postoperatively because of cerebrovascular accident. Atrial fibrillation was observed postoperatively in 1 patient. Five patients were diagnosed as squamous cell lung cancer by pathology examination, and 2 patients were adenocarcinoma. Follow-up ranging from 2 months to 59 monthswas available for these patients postoperatively. None of the patients showed evidence of angina and myocardial infarction after surgery. In one patient, who underwent left superior lobectomy, local recurrence was found at 19 months after surgery.

CONCLUSIONS

In selected patients, simultaneous radical lung resection and off-pump coronary artery bypass grafting is a safe and effective treatment when unstable coronary heart disease and lung cancer coexist. The therapeutic strategy may decrease the incidence of postoperative complications.
