This phase II trial assessed the toxicity and efficacy of irinotecan plus docetaxel in cisplatin-pretreated oesophageal cancer. Irinotecan 160 mg m(-2) plus docetaxel 65 mg m(-2) once every 3 weeks led to severe myelosuppression in four patients, all of whom experienced neutropenic fever. After amendment of this regimen, 24 patients (male/female=18/6; median age=58.5 years; ECOG performance status 0/1/2=9/11/4) with advanced oesophageal cancer (adenocarcinoma/epidermoid carcinoma=13/11) received irinotecan 55 mg m(-2) plus docetaxel 25 mg m(-2) on days 1, 8 and 15 of a 28-day cycle. Serious adverse events occurred in five patients, one with lethal outcome (pneumonia). Haematological toxicity >or=3 degrees was rare, whereas nonhaematological toxicity >or=3 degrees was noted in nine out of 24 patients (asthenia in five patients, diarrhoea in three patients, nausea/emesis in two patients, constipation in one patient). Median survival time was 26 (range 2-70) weeks. Response rate, assessed according to the WHO criteria, was 12.5% (95% CI 2.7-32.4%); rate of disease stabilisation (partial remission and stable disease) was 33.3% (95% CI 15.6-55.3%) with a median duration of 18.5 (range 16-51) weeks. Although the nonhaematological toxicity proved to be considerable, weekly irinotecan plus docetaxel is feasible and shows some activity in extensively pretreated patients with oesophageal cancer.
