Some elderly patients may have reduced tolerance the standard therapy (chemotherapy doublets) for stage III/IV non-small cell lung cancer (NSCLC). Sunitinib malate (S), an oral, multitargeted kinase inhibitor, shows promise as 2nd-line NSCLC treatment. This study explored the safety/efficacy of S in elderly patients with previously untreated NSCLC.
disease control rate (DCR) at six-weeks.
overall response (OR, CR+PR), progression-free survival (PFS), time to progression (TTP), one-yr survival, quality of life (QOL), and safety.
S 37.5 mg daily/42-day cycle until PD or intolerable toxicity. Key inclusion: chemo-naïve stage IIIB/IV NSCLC (nonsquamous histology); ECOG PS=0-1; ≥ 70 years; normal organ function. Exclusion: hemoptysis, anticoagulation, or clotting diathesis. Other standard S-specific criteria applied.
63 patients enrolled/60 treated.
51 % male, 95 % white, median age 78 years (range, 70-88), 73 % ECOG=1, 97 % Stage IV, 83 % adenocarcinoma, 44 % prior surgery, 19 % prior radiation. With a median of 2 cycles (range, 1-16), DCR=63 %, OR=7 % (0 CR, 4 PR). Median follow-up=5.8 months (all; 15.9 months survivors), median PFS =3.0 months (range, <1-25.1), median TTP=4.5 months (range, <1-25.1), and 1-year survival=26.4 % [95 % CI: 15.9, 38.2]. QOL declined initially, but improved over time. TREATMENT-related adverse events included: fatigue (48.3 %); diarrhea (38.3 %); thrombocytopenia (33.3 %), anorexia (26.7 %), mucositis (25.0 %); nausea (25.0 %), dysgeusia (20.0 %), and neutropenia (20.0 %). Conclusions The study met its primary endpoint. S produced acceptable DCR and QOL improved; however, OR was disappointing (7 %) and toxicity was greater than expected. A biomarker to identify patients more likely to benefit from S is needed.
一些老年患者对标准治疗(化疗双联)可能耐受性降低,对于 III/IV 期非小细胞肺癌(NSCLC)患者。舒尼替尼马来酸盐(S)是一种口服、多靶点激酶抑制剂,作为二线 NSCLC 治疗药物有一定的前景。本研究旨在探索 S 在未经治疗的老年 NSCLC 患者中的安全性和疗效。
治疗 6 周后的疾病控制率(DCR)。
总缓解率(OR,CR+PR)、无进展生存期(PFS)、疾病进展时间(TTP)、1 年生存率、生活质量(QOL)和安全性。
S 每日 37.5mg/42 天周期,直至疾病进展(PD)或无法耐受毒性。主要纳入标准:未经化疗的 IIIB/IV 期 NSCLC(非鳞状组织学);ECOG PS=0-1;年龄≥70 岁;器官功能正常。排除标准:咯血、抗凝或凝血功能障碍。其他标准的 S 特定标准适用。
共纳入 63 例患者/60 例接受治疗。
51%为男性,95%为白人,中位年龄 78 岁(范围,70-88),73%ECOG=1,97%为 IV 期,83%为腺癌,44%有既往手术史,19%有既往放疗史。中位治疗周期数为 2 个周期(范围,1-16),DCR=63%,OR=7%(0 例 CR,4 例 PR)。中位随访时间为 5.8 个月(所有患者;15.9 个月的幸存者),中位 PFS=3.0 个月(范围,<1-25.1),中位 TTP=4.5 个月(范围,<1-25.1),1 年生存率为 26.4%[95%CI:15.9,38.2]。QOL 最初下降,但随着时间的推移有所改善。与治疗相关的不良事件包括:乏力(48.3%);腹泻(38.3%);血小板减少症(33.3%);厌食症(26.7%);黏膜炎(25.0%);恶心(25.0%);味觉障碍(20.0%)和中性粒细胞减少症(20.0%)。
该研究达到了主要终点。S 治疗产生了可接受的 DCR,QOL 得到改善;然而,OR 令人失望(7%),毒性大于预期。需要一种生物标志物来识别更有可能从 S 中获益的患者。
