Background: The combination of etoposide (E) and cisplatin
(P) is standard first line treatment for small
cell lung cancer (SLSC). A complete response
(CR) rate of 30-40% is seen in limited stage (LS)
and 10-20% in extensive stage (ES). Paclitaxel
(T) is an active agent in SCLC with 34 % partial
response rate (J Clin Oncol 1995 13:1430).
Previous Phase I (Semin Oncol 1997 Aug; 24 (4
Suppl 12): S12-144-S12-148) and Phase II (J Clin
Oncol 1999 17: 2309) studies have shown that the
combination of Paclitaxel-Cisplatin-Etoposide
(TEP) was active in SCLC. This multicenter Phase
III trial was designed to compare the activity
and toxicity of TEP versus EP in untreated
patients with SCLC.
Materials and Methods:
Eligibility: Pts with a histologically
confirmed SCLC, age between 18-78, performance
status 0-2, no previous treatment, if CNS
metastasis present ? either stable or s/p
radiation (XRT) and with a life expectancy ³ 3
Cycles were repeated every 28 days.
Responding limited stage (LS) pts proceed to
thoracic XRT after completion of chemotherapy and
then prophylactic cranial irradiation (PCI)
The study was stopped prematurely due to
excessive toxicity of TEP regimen.
133 chemotherapy-naïve SCLC patients were
randomized to receive either:
TEP - T 175 mg/m2 IV-3hrs D-1, E 80mg/m2/d IV
D2-4, P 80mg/m2 IV D2, plus prophylactic G-CSF 5
mcg/kg/d SC D5-15 for all patients, or
EP - E 120mg/m2/d IV D1-3, P 80mg/m2 IV D1,
with G-CSF only for pts developing severe
62 pts received TEP and 71 EP with 49/62 and
69/71 evaluable for response/toxicity
Limited Stage (LS) was present in 29/62 (47%)
pts on TEP and 30/71 (41%) on EP.
Responses CR +PR: 3(5%) + 28(45%) for TEP and 3
(4%) + 30(42%) for EP (p=0.7).
Duration of response, median survival and 1-yr
survival were 7 and 10.5 mos and 43% for TEP vs.
6 and 11.5 mos and 45% for EP (p=NS).
In the subgroup analysis, TEP was more active
than EP in pts with extensive disease (p=0.03)
but without any survival benefit.
A total of 547 cycles of treatment have been
administered (241 TEP/306 EP) with a median of 4
and 5 cycles/pts respectively.
Dec 19, 2014 - In the treatment of non-small-cell lung cancer, gefitinib, an epidermal growth factor receptor inhibitor, may provide longer progression-free survival as compared to standard platinum doublet chemotherapy with cisplatin and docetaxel, according to a Japanese study published online Dec. 21 in The Lancet.
