Twenty-seven patients with non-small cell lung cancer were recruited i
nto a phase II study of single-agent vinorelbine using a 25 mg/m(2) we
ekly dose schedule. All patients were inoperable (stage III disease -
11 patients; stage IV disease - 16 patients). Median age was 64 years
(range: 37-72 years). Histological sub-types were squamous cell carcin
oma (15 patients), adenocarcinoma (8) and large cell carcinoma (4). Pa
rtial response was documented in 4 (16%) of 25 evaluable patients, and
stable disease in 13 (52%) patients. Median duration of response was
6.5 months (range 3-16 months) and median overall survival for patient
s with stable disease/partial response was 8 months (range 1-20 months
). Vinorelbine was generally well tolerated although WHO grade 3/4 tox
icity was noted for lethargy, constipation, alopecia (2 patients each)
, headache and non-tumour related bone pain (1 patient each). Vinorelb
ine is a moderately active single-agent in non-small cell lung cancer
and is currently undergoing evaluation as part of combination chemothe
rapy regimens.
