ABSTRACT
Objective To study the longterm result of endocrinotherapy and (or) radiotherapy for moderately and far advanced prostate cancer. Methods 256 cases of moderately or far advanced prostate cancer were treated with endocrinotherapy (surgical castration + postoperative drug administration) and (or) radiotherapy.182 cases were of stage C and 74 stage D.There were 236 adenocarcinoma,7 squamous cancer and 13 undifferentiated cancer.Gleason score was ≥6 in 202 patients and 134 had pelvic lymphoid metastasis. Results In 92.2%of the patients,the serum PSA dropped under 2 ng/ml shortly after the treatment.The overall 5,10,15 year survival rates were 48.8%,29.7% and 13.3% respectively.For stage C cases,these were 58.2%,38.4%,17.7% and for stage D 25.7%,6.4%,0.The 5 and 10 year survival rates were significantly different between stage C and D(P
ABSTRACT
Objective To analyse the long-term effect of non-small cell lung cancer treated with either postoperative irradiation(group A) or intraoperative radiotherapy(IORT) followed by postoperative irradiation(group B).Methods 154 patients with non-small cell lung carcinoma were randomized into two groups(groups A and B) with 77 patients in each.There were 134 squamous,17 adenocarcinoma and 3 adeno-squamous carcinoma.Seventeen patients had stage Ⅰ,76 stage Ⅱ and 61 stage Ⅲ lesions.The dose of postoperative irradiation in both groups was D_T4060?Gy.In group B,the IORT dose was 15-25?Gy,delivered by 9-16 ?MeV electrons.Results The local control rate was 49% and 62% in groups A and B,respectively(P0.05).Sixteen patients died of radiotherapy-induced complication: 2 in group A and 14 in group B.Conclusions Intraoperative radiotherapy followed by postoperative irradiation can enhance the local control rate of non-small cell lung cancer but can not improve the long term survival. The high complication mortality rate of IORT(18%) in contrast to that(3%) of postoperative radiotherapy is worth noticing.
