[Results of radiotherapy combined with CDDP (BAI) plus VP-16 in the treatment of inoperable non-small cell lung cancer].

Twenty-six patients with unresectable non-small cell lung cancer were treated by chemotherapy alone or chemotherapy followed by radiotherapy from June 1988 to May 1990. CDDP (80 mg/m2) was given by bronchial arterial infusion (BAI) on day 1 in each course, VP-16 (80 mg/body) was given by drip intravenous infusion on days 1 and 2, and VP-16 (150 mg/body) was given orally on days 3 and 5. The patients were irradiated after this regimen with a single dose of 1.8-2.0 Gy, five times each week, to a volume which encompassed only the primary tumor. A total dose of 60 Gy or more was delivered. There were 10 squamous cell carcinomas, nine adenocarcinomas, five large cell carcinomas, one adenosquamous cell carcinoma and one poorly differentiated carcinoma. Median survival time (MST) was 354 days in stage III B patients and 280 days in stage IV patients. MST was 155 days in adenocarcinoma and 310 days in squamous cell carcinoma. MST was 372 days in PS 0 to 1 patients and 140 days in PS 2 patients. With chemo-radiotherapy in 17 cases resulted in no complete remissions and 10 partial remissions. The overall response rate was 58.8%. It is concluded that CDDP via BAI combined with VP-16 administration and sequential irradiation is useful to acquire a high response rate in non-small cell lung cancer. However, further studies on this modality are required.

[Treatment results of small cell lung cancer: referring to the clinical value of BAI combined with radiotherapy].

Results of 65 cases of small cell lung cancer (SCLC) treated from Jan. 1981 to May 1991 were reviewed. There were 58 male and 7 female patients and their age was ranging from 37 to 86 (mean 65). There were 41 limited disease (LD) and 24 extensive disease (ED) cases. According to TNM (UICC 1987) staging system, there were 2 cases of stage I, 4 of stage II, 9 of stage III A, 28 of stage III B and 22 of stage IV. Among 65 cases, 60 cases received radiotherapy and 55 cases of them received radiotherapy for primary site. There were 29 cases received radiotherapy combined with BAI (bronchial artery infusion) and 20 cases received systemic chemotherapy. On survival, the 2-year survival rate was 26% and MST was 13 months in LD patients (n = 41). No 2-year survivors were seen in ED patients and MST was 10 months. Tumor response of primary site was as follows. In systemic chemotherapy group, CR 35%, PR 59%, NC 6% and PD 0% before radiotherapy and CR 59% after radiotherapy were obtained. In BAI group (including BAI + systemic chemotherapy), CR 6% and PR 88% before radiotherapy in BAI group. BAI did not seem to improve response rate compared to systemic chemotherapy. On survival, BAI group did not show significant better survival compared to BAI (-) group in LD cases (n = 31). In responders (evaluable LD cases, n = 24), the MSTs were 25 months in CR cases and 13 months in PR cases. No 2-year survivors were seen in PR cases.(ABSTRACT TRUNCATED AT 250 WORDS)

[Results of radiotherapy combined with BAI (bronchial artery infusion) for non-small cell lung cancer--analysis of 104 cases].

Results of 104 cases of non-small cell lung cancer (NSCLC) treated by radiotherapy combined with BAI (bronchial artery infusion) were analyzed retrospectively. In 104 cases (84 males and 20 females), 14 cases of stage I, 10 of stage II, 33 of stage IIIA, 29 of stage IIIB and 18 cases of stage IV were included. Overall cumulative survival rate was 11.4% and 50% survival time was 12 months. On PS (performance status), 50% survival time was 1 year and 3 months for both PS 0 and PS 1, 8 months for PS 2 and 2 year for PS 3 (n = 3), respectively. On stage, 50% survival time was 3 year and 4 months for stage I, 1 year and 2 months for stage II, 12 months for stage IIIA, 11 months for stage IIIB and 8 months for stage IV. There was no significant difference of survival rate between squamous cell carcinoma (n = 41) and adenocarcinoma (n = 43). On anticancer agents used for BAI, CDDP group (n = 68) showed better significant 2-year survival rate than that of MMC and/or ADR group (n = 36). Response rate (CR + PR) was 85% (75/88) by radiotherapy with BAI, and 10 cases of CR were obtained. Among 27 cases of 2-year survivors, 21 cases of responders (CR + PR) were included and 4 cases of them showed CR. On these results, radiotherapy combined with BAI seemed to contribute to improve long-term treatment results of NSCLC by higher response rate with the progress of anticancer agent used for BAI.
