Analysis of the results obtained in elderly (75 years and older) included a phase II trial combining intra-arterial cisplatin and concurrent radiation into invasive bladder cancer.
Thirty-five patients (28 males and 7 females) were accrued from 1985 to 1996. There were 1 Ta, 4 T2, 11 T3A, 12 T3B, 3 T4A, and 4 T4B patients. Nine had unilateral hydronephrosis and two bilateral hydronephrosis. There were 28 transurethral resections which were incomplete in 23 patients. Intra-arterial cisplatin was given as 2-4 hours infusion (60-90 mg/m2) split through both internal iliac arteries on day 1, 14, 21, and 42. Irradiation to the pelvis was started on day 14 and consisted of 40 Gy/20 fractions followed by a boost of 20 Gy/10 fractions to the tumor with margins of 2 cm.
Thirty (86%) completed fully the protocol. One patient died from sepsis secondary to the treatment. The tumor response was evaluable in 29 patients and complete response was observed for 27 of them. Five of these 27 patients had an isolated bladder relapse which was salvaged by cystectomy in two patients. There were 11 deaths from bladder cancer (31% of the patients): 9 from distant metastase, one from local failure, and one from treatment.
This combined modality yields excellent results with high complete response rate and good tolerance. This approach may therefore be particularly appropriate for the elderly.
对老年(75岁及以上)患者进行的结果分析包括一项将动脉内顺铂与同步放疗相结合治疗浸润性膀胱癌的II期试验。
1985年至1996年共纳入35例患者(28例男性和7例女性)。其中Ta期1例、T2期4例、T3A期11例、T3B期12例、T4A期3例、T4B期4例。9例有单侧肾积水,2例有双侧肾积水。28例行经尿道切除术,其中23例切除不完全。动脉内顺铂在第1、14、21和42天通过双侧髂内动脉分2 - 4小时输注(60 - 90mg/m²)。盆腔放疗于第14天开始,剂量为40Gy/20次分割,随后对肿瘤追加20Gy/10次分割,外放2cm边界。
30例(86%)完全完成方案。1例患者死于治疗继发的败血症。29例患者的肿瘤反应可评估,其中27例观察到完全缓解。这27例患者中有5例出现孤立性膀胱复发,2例通过膀胱切除术挽救。11例死于膀胱癌(占患者的31%):9例死于远处转移,1例死于局部衰竭,1例死于治疗相关原因。
这种联合治疗方式产生了优异的结果,完全缓解率高且耐受性良好。因此,这种方法可能特别适合老年人。
