[Investigation of lung cancer patients with cardiovascular disease]

According to the aging in Japan, surgery of lung cancer with cardiovascular disease is increasing. Among them, the merger of the heart and large blood vessel disease would be expected to be directly linked to the perioperative management.

We conducted a retrospective analysis of 1,005 patients who had undergone surgical resection of primary lung adenocarcinoma between January 1997 and June 2014 at Hokkaido University Hospital. Among them, 81 patients had more than one cardiovascular disease.

The median age was 71 years old. Men are 62 cases(76%). 64 cases (79%)had smoking history. Ischemic heart disease( IHD) was 29 cases(33%), followed by atrial fibrillation(Af), arrhythmia other than Af, valve disease and macrovascular disease. Anticoagulant or antiplatelet therapy were preoperatively done in 41% of IHD cases, 39% of Af cases. Thirty four% of IHD, 50% of vascular disease received the treatment other than medication. Video-assisted thoracic surgery was performed in 67 cases(83%). Lobectomy, sublobectomy were performed for 59 cases(73%), 19 cases(23%), respectively. Postoperative complications were occurred in 32 cases(40%). Two patients(2.5%)died in hospital without discharge. Univariate analysis revealed tumor size, pStage, lymph node dissection, operation time or blood loss were correlated with postoperative complication.

For the patients with cardiovascular disease, careful evaluation of surgical indication, perioperative management is required.
