The combination of docetaxel, cisplatin and fluorouracil is considered to be one of the reference regimens for advanced gastric cancer, but due to its major myelotoxicity, its use in clinical practice has become limited. This prospective phase II study evaluated the activity and toxicity of a modified regimen with lower doses of docetaxel and cisplatin combined with oral capecitabine instead of fluorouracil for patients with advanced gastric cancer. Treatment consisted of docetaxel at 60 mg/m(2) i.

Purpose: To determine the dose-limiting toxicities (DLTs) and the maximum tolerated doses (MTD) of oral metronomic vinorelbine with capecitabine in patients with metastatic breast cancer (MBC).

Patients And Methods: Escalated doses of oral metronomic vinorelbine (starting dose 30 mg) every other day continuously and capecitabine (starting dose 800 mg/m(2) bid) on days 1-14 every 21 days were administered. DLTs were evaluated during the first cycle.

A randomized multicenter phase III study was conducted to compare the sequential docetaxel followed by epirubicin/cyclophosphamide combination with that of FEC regimen as adjuvant chemotherapy in women with axillary node-positive early breast cancer. Seven hundred and fifty-six women with axillary lymph node-positive breast cancer were randomized to receive either 4 cycles of docetaxel (100 mg/m(2)) followed by 4 cycles of epirubicin (75 mg/m(2)) plus cyclophosphamide (700 mg/m(2)) (experimental arm) or 6 cycles of FEC (epirubicin 75 mg/m(2), cyclophosphamide 700 mg/m(2), and 5-fluorouracil 700 mg/m(2); control arm). All regimes were administered every 3 weeks.

There is no standard treatment for breast cancer patients whose tumors have been exposed both to anthracyclines and taxanes. Oxaliplatin shows synergism with 5-fluorouracil (5-FU) and capecitabine is an oral prodrug of 5-FU with known efficacy in pretreated patients. This phase II trial studied the efficacy and toxicity of the oxaliplatin-capecitabine combination as salvage treatment in breast cancer patients pretreated with anthracyclines and taxanes.

Background: The role of combination chemotherapy regimens in the management of ovarian cancer patients with tumors previously exposed to platinum compounds and paclitaxel has not yet been defined. The present phase II study evaluated the activity and toxicity of a gemcitabine-ifosfamide-cisplatin combination in the aforementioned group of patients. Given the in vitro and in vivo synergism between the three agents, it was believed that using a three-drug combination would overcome tumor resistance to cisplatin.

Disseminated malignancy is the major cause of prostate cancer-related mortality. Circulating tumor cells (CTCs) are essential for the establishment of metastasis. Various contemporary and molecular methods using prostate-specific biomarkers have been applied to detect extraprostatic disease that is undetectable by conventional imaging techniques, assessing the risk for disease recurrence after therapy of curative intent.

Background: Oxaliplatin has become one of the major cytotoxic agents for the treatment of gastrointestinal tumors. As a result, several cases of the so-called oxaliplatin-associated hypersensitivity reaction have been documented.

Patients And Methods: We have retrospectively evaluated and characterized these reactions in our patient group by reviewing the files of 1,224 patients exposed to an oxaliplatin-containing regimen in order to provide useful clinical information for diagnosis and management.

Objective: To investigate the efficacy and toxicity of gemcitabine administration followed by the combination of fluorouracil (5-FU) modulated by folinic acid in patients with advanced, symptomatic pancreatic cancer. The main objective was to estimate tumour response and any improvement in patients' quality of life.

Patients: The study included 48 evaluable patients with metastatic disease with no prior chemotherapy.

The role of docetaxel in combination with cisplatin in the management of gastric cancer resistant to first-line chemotherapy has not yet been defined. This multicenter prospective phase II study evaluated the activity and toxicity of the docetaxel-cisplatin combination in gastric cancer patients, whose tumors were primarily resistant to first-line chemotherapy or had tumor recurrence after chemotherapy. Treatment consisted of docetaxel 70 mg/m2 i.

The role of combination chemotherapy regimens in the management of ovarian cancer patients with tumors resistant to platinum compounds has not yet been defined. This multicenter prospective phase II study evaluated the activity and toxicity of the docetaxel-plus-irinotecan combination in ovarian cancer patients whose tumors were resistant to platinum compounds and who had been exposed to paclitaxel. Treatment consisted of docetaxel 60 mg/m2 i.

The docetaxel-cisplatin combination is active against several tumors including gastric cancer but it is followed by severe myelosuppression. Recent experience with weekly taxanes has demonstrated a mild myelotoxicity with high dose intensity. We investigated in a phase I study a weekly schedule of docetaxel on days 1, 8 and 15 and cisplatin on day 1 every 4 weeks in 19 patients with advanced gastric cancer with no prior chemotherapy.

This phase II trial studied the efficacy and toxicity of docetaxel-epirubicin, supported by granulocyte colony-stimulating factor, as first-line chemotherapy in metastatic breast cancer. Patients received epirubicin (60 mg/m2) followed 1 hour later by docetaxel (80 mg/m2) every 3 weeks for a maximum of 8 cycles or until disease progression. Prophylactic granulocyte colony-stimulating factor (5 micrograms/kg) was administered daily for 5 days.
