摘要
:背景:两个病例报告描述了针对IRESSA失败后TARCEVA的效果(Garfield DH, J Clin Oncol 2005 ) ,或 TARCEVA失败后IRESSA的效果。(Choong NW et al, 临床实用肿瘤2006年) 对 晚期非小细胞肺癌的患者. 另外, 有限的经验,在5病例表明TARCEVA不能有效正进行IRESSA治疗的患者, ((Viswanathan A et al, ,肺癌2005 ) .
此项研究的目的是评价,对晚期非小细胞肺癌TARCEVA治疗 失败后,用IRESSA的效果和疾病进展时间( TTP ),
方法:
病人得到150毫克/天TARCEVA治疗,之后病情进展( PD ).
病人收到250毫克/天的IRESSA治疗,试验被停止了,由于2006年8月TARCEVA被批准在意大利使用和随之而来的禁止IRESSA的慈善使用. 结果
从2005年5月至2006年8月,15个病人注册试验. 年龄中位数65岁( 1950年至1985年) ; =男性14例( 93% ) ; 从不/从前吸烟者=4 / 10例(67分之26% ) ;腺癌10例( 67% ) ;
PS 0 / 1 = 5 / 10例(67分之33% ) ; 在2例中(占13% )TARCEVA被作为第一线治疗, 8例病人( 53% ) 以前得到2个化疗( CT ) ,3例( 20% ) , 在TARCEVA和IRESSA之间接受CT,接受TARCEVA治疗后, 其中一名病人( 7% ) 部分缓解( PR ) , 5例( 33% )疾病稳定,接受IRESSA治疗后,没人部分缓解(PR) ,和6个稳定(SD)( 40% ) ,6个接受TARCEVA治疗后获得部分缓解或稳定的,接受IRESSA治疗后,5个是稳定, 9个接受TARCEVA治疗后进展的病人中,8人接受IRESSA治疗后仍进展,1个TARCEVA稳定,IRESSA进展,一个TARCEVA进展,但IRESSA是稳定,部分有效(RP) 和稳定(SD病人的TTP,TARCEVA和IRESSA分别是7.2和3.4个月; 进展病人(PD)的TTP,TARCEVA和IRESSA分别是1.7和1.6个月。
结论: 我们的资料显示, 对那些对TARCEVA是部分缓解(PR)或稳定的(SD) 的病人,,同时有与良好的TTP,IRESSA是有好益的。. 反之,TARCEVA后立即进展的病人,不推荐IRESSA。此外,这些研究结果支持基本理由--治疗进展的病人使用这种或那种EGFR TKI; 也许值得收集更多的关于TARCEVA的数据
Gefitinib (G) treatment outcome after progression on erlotinib (E) in patients with advanced non-small cell lung cancer (NSCLC). Sub-category: Non-Small Cell Lung Cancer Category: Lung Cancer Meeting: 2007 ASCO Annual Meeting Printer Friendly E-Mail Article Abstract No: 18138 Citation: Journal of Clinical Oncology, 2007 ASCO Annual Meeting Proceedings Part I. Vol 25, No. 18S (June 20 Supplement), 2007: 18138 Author(s): F. Grossi, A. Brianti, C. Defferrari, M. Loprevite, G. Catania, P. Pronzato Abstract: Background:
Two case reports describe a response to E after failure of G (Garfield
DH, J Clin Oncol 2005) or to G after failure of E (Choong NW et al, Nat
Clin Pract Oncol 2006) in patients (pts) with advanced NSCLC.
Otherwise, a limited experience in 5 pts suggests that E is not
effective in pts progressing on G (Viswanathan A et al, Lung Cancer
2005). Aim of this study was the evaluation of response and time to
progression (TTP) in advanced NSCLC pts treated with G after failure of
E. Methods: Pts received G 250 mg/day after disease progression (PD)
with E 150 mg/day. Pts accrual was stopped on August 2006 after the
approval of E for use in Italy
and the consequent closure of the G compassionate-use program. Results:
From May 2005 to August 2006, 15 pts were enrolled. Median age 65 years
(50-85); males= 14 pts (93%); never/former smokers= 4/10 pts (26/67%);
adenocarcinoma= 10 pts (67%); PS 0/1= 5/10 pts (33/67%); in 2 pts (13%)
E was administered as first-line therapy, 8 pts (53%) received 2 prior
lines of chemotherapy (CT) and 3 pts (20%) received CT between E and G.
One patient (7%) had a partial response (PR) and 5 pts (33%) had
disease stabilization (SD) with E; with G no PR and 6 SD (40%) were
obtained. Five out of 6 RP/SD pts with E, had SD with G; 8 out of 9 PD
pts with E, had PD with G; 1 SD patient with E, progressed with G and 1
vice versa. TTP in RP/SD pts was 7.2 and 3.4 months for E and G
respectively; in PD pts TTP was 1.7 and 1.6 for E and G respectively.
Conclusions: Our data suggest that there is a benefit with G in pts who
had RP/SD with E and that is associated with a good TTP. Conversely G
is not recommended in pts that immediately progressed after E. Moreover
these results support the rationale of treating PD pts with an EGFR TKI
with another one; it may be worthwhile to collect more data on E.
