Multicenter Study Clinical Trial
A phase II study of oral eniluracil/fluorouracil in patients with anthracycline-refractory or anthracycline- and taxane-refractory advanced breast cancer.
Eniluracil is an effective inactivator of dihydropyrimidine dehydrogenase, the initial and rate limiting enzyme in the catabolism of fluorouracil. The current study was done to determine the objective tumour response of a 28-day oral regimen of eniluracil-fluorouracil in patients with advanced breast cancer. ⋯ Treatment with oral eniluracil-fluorouracil was well tolerated by patients with advanced breast cancer. The efficacy data were comparable with those of other published studies in this group of refractory patients.

Metastatic soft tissue sarcoma not amenable to curative surgery has a dismal prognosis. Aggressive treatment with anthracyclines and ifosfamide represents the current therapeutic mainstay in these patients, most of whom succumb to relapses. Thus, the efficacy of subsequent therapeutic approaches has to be weighed against toxicity caused by palliative treatment. ⋯ Our results suggest that docetaxel represents an efficacious and tolerable treatment in a minority of patients refractory to standard treatment. There is a need for better identification of patients most likely to benefit from salvage treatment with docetaxel.

Clinical Trial
A pilot study of chronomodulated infusional 5-fluorouracil chemoradiation for pancreatic cancer.
Dose limiting acute toxicity from chemoradiation for pancreatic cancer occurs in 15% -20% of patients treated with post-operative adjuvant therapy. Reported here is a pilot study using chronomodulated infusional 5-fluorouracil (5-FU) chemoradiation (CIC) for pancreatic cancer, a treatment designed to reduce normal tissue toxicity and maintain efficacy, with specific evaluation of acute and late morbidity, patterns of disease progression, and survival. ⋯ Acute toxicity of 5-FU CIC appears to be less frequent and less severe than that reported with flat infusional or bolus 5-FU based chemoradiation used for adjuvant post-operative therapy for pancreatic cancer. This method may warrant further examination, as it may be attractive for the elderly or those who cannot tolerate the toxicity associated with standard post-operative treatment protocols.

Randomized Controlled Trial Multicenter Study Comparative Study Clinical Trial
A multicenter randomized clinical trial comparing paclitaxel-cisplatin-etoposide versus cisplatin-etoposide as first-line treatment in patients with small-cell lung cancer.
Previous phase I-II studies have shown that the combination of paclitaxel-cisplatin-etoposide (TEP) is very active and well tolerated in patients with small-cell lung cancer (SCLC). In order to compare the TEP combination to cisplatin etoposide (EP) regimen as front-line treatment in patients with SCLC, we conducted a randomised multicenter study. ⋯ In this early terminated study, the TEP regimen was significantly more toxic than the EP regimen. The TEP regimen is associated with significant toxicity and mortality, and should not be used outside of a protocol setting. For future investigations, dose and schedule modifications are necessary to reduce toxicity.
