[Assessment of surgical treatment for lung cancer with pericardial or left atrial invasion].
We evaluated surgical results for the patients who underwent pulmonary resection combined with pericardial or left atrial resection due to locally advanced non-small cell lung cancer (NSCLC). Seven patients who underwent pericardial resection (T3 group) and 4 patients who underwent resection of the left atrium (T4 group) were included in this study, and clinical findings and prognosis were evaluated. Eight patients underwent pneumonectomy, and others underwent lobectomy or bilobectomy. Histology of the cancer was squamous cell carcinoma in all patinets. As for pathological node involvement, N0/N1 disease was 72.7% and N2 disease was 27.3%. Induction chemotherapy was performed in 75.0% of T4 group. Adjuvant chemotheraphy was performed in 71.4% of T3 group and 75.0% of T4 group. Five-year-survival was 57.1% in T3 group and 25.0% in T4 group. Five-year-survival was 62.5% in N0/N1 disease and 0% in N2 disease. Statistical significance in prognosis was seen in lymph node status (p = 0.0317). Extended resection of pericardium or left atrium for patients with N2 disease of NSCLC is not recommended. When invasion to pericardium or left atrium is diagnosed during surgery, extended resection should be indicated in patient without N2 metastasis.
