Two cases of combined thoracoscopy and open chest surgery for locally advanced lung carcinoma

Thoracoscopic surgery is becoming more widely used in thoracic surgery and has an increasingly important role to play. However, its use for locally advanced carcinoma (clinical stage T3–4) remains controversial. We adapted our procedure by combining thoracoscopy and open chest surgery (combination surgery) with the aim of reducing invasiveness while ensuring that the operation is safe and curative. Here we describe our experience. Case 1 was a man in his 60s who underwent induction chemoradiotherapy (cisplatin plus vinorelbine plus 40 Gy radiotherapy) followed by radical surgery for a left apical lung carcinoma with chest wall invasion. Case 2 was a woman in her 70s who repeatedly had pneumonia and who underwent radical surgery for left apical adenocarcinoma that was expected to have strong adhesions to the thoracic wall. A thoracotomy incision may be required in cases of stage T3–4 lung cancer to access the hilar region and dissect the resected tumor and surrounding organs. In such cases, adding thoracoscopy to either one of these procedures may enable the use of a smaller incision in the chest wall. In both cases, complete resection with no residual tumor or complications was achieved, with the patients being discharged 3–8 days postoperatively. Cases 1 and 2 both remain recurrence free after 1.5 and 3 years, respectively). This suggests that having a thorough understanding of the features of both thoracoscopic and open chest surgery and integrating the two may enable surgery to be safely and less invasively performed while ensuring a curative effect.
