Recently, there are so many chances to find out the early stage lung cancer, because of the raising efforts for discovering the lung cancer and the wide spread usage of sputum cytological examination. Of course, the surgical therapy should be the first choice for these cases, but the inoperable cases are increasing due to the aging, low pulmonary function and severe complications.
We have performed photodynamic therapy (PDT) in 40 cases of early stage lung cancers (45 lesions) during this 9 years. In these cases, 26 cases were disease free in 14 to 104 monthes after the PDT. But 4 cases were revealed the recurrence of cancer.
In this paper, we examine the indication of the PDT for the early cancer.
