title: Brain metastases in patients with limited small cell lung cancer achieving complete remission. Correlation with TNM staging.
abstract: We reviewed the brain metastases, after treatment, of 45 patients with limited small cell lung cancer who achieved complete remission by radiochemotherapy or curative operation. No patient received prophylactic cranial irradiation. The incidence of subsequent brain metastases was classified according to pretreatment staging as follows: two of 13 (15 percent) patients in stage I; two of ten (20 percent) in stage II; nine of 17 (53 percent) in stage IIIa; and four of five (80 percent) in stage IIIb. The brain metastases occurred from seven to 29 months after the start of treatment, and the median time of the occurrence was 13 months. Of 17 patients who developed brain metastases and who subsequently received cranial irradiation, there were two in whom relapse had occurred at no other site except the brain and who survived 26 and 79 months after the relapse, respectively. These data indicate that not all patients with limited SCLC achieving CR due to treatment necessarily benefit from PCI.
