[Surgical treatment for lung cancer cases with an interlobar pleural involvement]

Among surgically resected 192 lung cancer cases, eleven with a interlobar pleural involvement (p 3) were studied to clarify their characters. The five year survival rate of interlobar p 3 was 12.5% (15.6% in case of excluding death of other diseases), which was better than that of the other parietal p 3. Result of surgical treatment of lobectomy + partial resection for interlobar p 3 had better tendency compared with that of bilobectomy or pneumonectomy. But, unfortunately it was necessary for interlobar p 3 to care the local recurrence in the future. We hope that the general rule of the treatment for interlobar p 3 was carefully discussed furthermore, including the safety margin in the partial resection or the classification on T factor.
