    ABSTRACT: The aim of this study was to evaluate the survival benefit of adjuvant chemotherapy with etoposide, leucovorin and 5-fluorouracil (ELF) in gastric cancer patients undergoing previous surgery with a curative intent. The clinical outcome of 49 patients with resected gastric cancer treated with adjuvant chemotherapy was compared with that of 85 surgically treated historical controls who did not receive any adjuvant treatment. The chemotherapy regimen consisted of six cycles of daily 1-hour intravenous infusions of folinic acid 100 mg/m2 and 5-FU 400 mg/ m2, and a 2-hour infusion of etoposide 100 mg/m2, for three days every 28 days. The 5-year relapse-free survival was 32% in the adjuvant arm and 27% in the control arm (p = 0.6). At the last follow-up, there were 32 deaths in the adjuvant arm and 60 in the control arm. The median duration of survival was respectively 23 and 19 months, and the 5-year survival rates were 34% and 29% (p = 0.4). The chemotherapy was well tolerated. Our data suggest that ELF adjuvant treatment is a safe and well tolerable combination chemotherapy in patients with resected gastric cancer, but it does not seem to improve prognosis in comparison with historical controls.

    ABSTRACT: Previous results suggest that GEM affects 5-fluorouracil (5-FU) metabolism and pharmacokinetics in cancer patients, while combined with oxaliplatin, levo-folinic acid, and 5-FU (GOLF regimen), at doses achievable in cancer patients, determines high cytotoxic and proapoptotic antitumour activity in colon cancer cells in vitro. On these bases we designed a phase I-II clinical trial testing the GOLF regimen in patients with metastatic colorectal carcinoma, who had received at least a prior line of chemotherapy. In total, 29 patients (20 males and nine females) enrolled in the study received every 2 weeks, gemcitabine (patients #1-3 received 600 mg m(-2); patients # 4-6 received 850 mg m(-2); while patients # 7-29 received 1000 mg m(-2)) on the day 1, levo-folinic acid (100 mg m(-2)) on the days 1 and 2; 5-fluorouracil (400 mg m(-2)) in bolus injection, followed by a 22-h continuous infusion (800 mg m(-2)) on the days 1 and 2, and oxaliplatin (85 mg m(-2)), 6 h after the 5-FU bolus on day 2. The most frequent side effect was grade I-II haematological toxicity. In total, 28 patients were evaluable for response: three achieved a complete response, nine a partial response, 10 had a stable disease, and six progressed. The average time to progression and overall survival of the patients was, respectively, 7.26 and 22 months. Our GOLF combination is well tolerated and seems promising for the treatment of advanced colorectal cancer.

    ABSTRACT: This phase II clinical trial was performed in order to evaluate the pharmacokinetics, toxicity and anti-tumor activity of a novel combination of gemcitabine (GEM), 5-fluorouracil (5-FU) and folinic acid (FA) designed on a specific translational basis. Every 4 weeks, 44 patients with various gastroenteric malignancies, 29 of whom had pancreas carcinoma, received a short intravenous (i.v.) infusion of FA (100 mg/m2) and 5-FU (400 mg/m2) on days 1-5, and GEM 1000 mg/m2 on days 1, 8 and 16. Our results suggest that, although this treatment leads to hematological and gastroenteric toxicity, it is very active in patients with pancreatic carcinoma. We therefore believe that an improved version would merit further investigation in larger scale trials.

    ABSTRACT: To investigate the prognostic value of some conventional bone markers and a number of other factors in terms of the survival of patients with hormone-resistant prostate cancer and bone metastases treated with chemotherapy. The data of 141 patients were analyzed to verify the influence of the following factors on survival: bone-alkaline phosphatase, type I collagen propeptide, the carboxyterminal telopeptide of type I collagen, the urinary calcium/creatinine ratio, patient age, Karnofsky performance status, pathologic grade, duration of response to primary hormonal therapy, prostate-specific antigen, hemoglobin, lactate dehydrogenase, and extent of bone disease. When all the variables were simultaneously analyzed using the multivariate proportional hazard model, only Karnofsky performance status (P <0.005) and duration of response to primary hormonal therapy (P <0.0001) remained statistically significant. The results of this study suggest that bone-alkaline phosphatase, type I collagen propeptide, the carboxyterminal telopeptide of type I collagen, and the urinary calcium/creatinine ratio are not prognostic of survival in patients with hormone-resistant prostate cancer and bone metastases treated with chemotherapy.

    ABSTRACT: A total of 41 metastatic colorectal cancer (CRC) patients received tegafur/uracil (UFT)+leucovorin (LV)+oxaliplatin alternated with UFT/LV+irinotecan. The overall response rate was 58.5% (95% confidence interval, 42.2-73.3%), and the median progression-free survival was 8.8 months. There were no grade 4 toxicities; 12 patients (29%) experienced grade 3 diarrhoea. There were no cases of hand-foot syndrome. This alternating regimen seems to be effective and well tolerated in the first-line treatment of patients with metastatic CRC.

    ABSTRACT: Pancreatic adenocarcinoma is a common disease considered to be poorly responsive to antiblastic treatment. Recent clinical and preclinical results suggest that a combined treatment of gemcitabine (GEM), 5-flurouracil (5-FU) and folinic acid (FA) offers a clinical benefit in patients with advanced pancreas adenocarcinoma. The aim of this phase II clinical trial was to evaluate the antitumour activity and toxicity of a novel biweekly schedule of this combination in patients with pancreatic adenocarcinoma. A total of 42 patients received a 30 min infusion of FA (100 mg m(-2)) and 5-FU (400 mg m(-2)) (FUFA) on days 1-3, and GEM 1000 mg m(-2) on day 1 every 15 days. We observed 13 objective responses (two complete, 11 partial) and 23 stable diseases. The median time to progression was 9.75 months (95% Confidence Interval (CI), 6.88-12.62) and the median overall survival was 13.10 months (95% CI 9.64-16.56). There were seven cases of each grade III gastroenteric and haematological toxicity. The GEM plus FUFA combination appears to be well tolerated and very active in patients with pancreatic carcinoma.

    ABSTRACT: A number of recent clinical trials testing the combination of 5-fluorouracil (5-FU) and gemcitabine in patients with advanced pancreatic adenocarcinoma have shown a significant clinical response rate, but also significant toxicity. As the two antimetabolites may interact at several biochemical levels along their pathways of activation, we investigated whether gemcitabine (GEM) affects 5-FU pharmacokinetics in cancer patients. Thus, we compared 5-FU pharmacokinetics in two groups of patients with various cancers who received the same schedule of 5-FU and folinic acid (FUFA), with or without GEM. There was a significant increase in systemic (5-FU) exposure and toxicity in the FUFA plus GEM group. Our finding may be useful in designing future studies of the combination in order to reduce the occurrence of side-effects and to maximise the antitumour activity.

    ABSTRACT: The aim of this study was to evaluate the activity and tolerability of docetaxel in patients with hormone-resistant prostate cancer previously exposed to chemotherapy. We enrolled 27 patients with hormone-resistant prostatic cancer that had progressed during first-line chemotherapy. The primary end-point was palliative response defined as a 2-point reduction in the 6-point present pain intensity scale, and an improvement in Karnofsky performance status of one 10-point category. The treatment consisted of weekly docetaxel 25 mg/m(2) body surface area administered by means of a 1-hour intravenous infusion with corticosteroid premedication. The primary criterion of palliative response was met in 13 patients (48%) after eight treatment cycles; its median duration was 6 months (range 1-8). Mean global quality of life improved in 8 and 10 patients after respectively four and eight treatment cycles. After a median follow-up of 8 months, 21 patients had died: the median survival was 9+ months (range 2-18). Weekly docetaxel was very well tolerated: grade 3 neutropenia occurred in 1 patient and grade 3 anemia in 2. Weekly low-dose docetaxel is an effective and well-tolerated treatment for patients with hormone-resistant prostate cancer previously exposed to chemotherapy.

    ABSTRACT: The role of salvage chemotherapy in advanced non-small cell lung cancer (NSCLC) is still controversial, but the recent development of a number of active antineoplastic agents has created new possibilities for disease management. The aim of this study was to evaluate the activity and safety of weekly docetaxel treatment in patients with advanced NSCLC previously treated with two chemotherapy regimens. The study involved 26 patients with histologically documented stage IIIB, IV or recurrent metastatic NSCLC previously treated with two non-taxane based-chemotherapy regimens. They all received docetaxel 25 mg/m(2)/week administered as a 1-h infusion in an outpatient setting with corticosteroid premedication. Fourteen of the 26 patients (54%) had distant metastases and 12 (46%) chest-localised disease. Six patients (23%; confidence interval: 9.8-44.1%) showed a partial response, 8 (31%) stable disease, and 12 (46%) progressive disease. The median time to progression was 4 months (range 2-8), and the median survival was 7+ months (range 3-13+). There were no statistically significant differences between the global quality of life scores recorded at baseline and those recorded after subsequent cycles. The treatment was very well tolerated. The results of this study suggest that weekly low-dose docetaxel is effective, well tolerated and maintains a relatively good quality of life in patients with advanced NSCLC previously exposed to two chemotherapy regimens.

    ABSTRACT: To assess the activity and safety of combined folinic acid (FA), 5-fluorouracil (5-FU) and mitomycin C (MMC) in metastatic breast cancer patients previously treated with at least two chemotherapy regimens. A total of 104 consecutive patients were enrolled for treatment with FA 100 mg/m(2) plus 5-FU 400 mg/m(2) i.v. on days 1-5, and MMC 3 mg/m(2) on days 3-5 (FFM). The cycles were repeated every 21 days until progression, severe toxicity or patient refusal. Of the 104 patients, 96 were evaluable for response and toxicity. The overall response rate was 43% (95% confidence interval 32.8-53.2%); 40 patients achieved stable disease (42%) and 15 progressed (15%). In a retrospectively defined subgroup of patients with clinical resistance to taxanes (12 patients) or anthracyclines (14 patients), the response rate was 42%. The median time to progression was 8 months (3-18 months), and the median overall survival was 10.5+ months (2-36 months). The most common treatment-related adverse events were stomatitis, neutropenia, nausea/vomiting and diarrhea. Stomatitis, neutropenia and thrombocytopenia were the only grade 4 treatment-related adverse events, and occurred in no more than 3% of patients. The tested FFM regimen seems to offer a valid option for patients with metastatic breast cancer who have been pretreated with two or more chemotherapeutic lines or who have failed on regimens containing anthracyclines or taxanes.

    ABSTRACT: This randomized study compared the efficacy of epirubicin-based adjuvant chemotherapy on the disease-free interval (DFI) and overall survival of patients with high-risk soft-tissue sarcomas. After curative surgery, 43 of the 88 enrolled patients were assigned to surgery with or without radiotherapy and 45 to surgery plus chemotherapy (26 epirubicin, 19 epirubicin + ifosfamide) with or without radiotherapy. The trial closed prematurely because of poor patient accrual. There was a statistical significant difference in the 5-year disease-free survival of the patients receiving adjuvant chemotherapy with or without radiotherapy (69%) and that of those treated with surgery with or without radiotherapy (44%) ( p= 0.01). The 5-year survival of the patients treated with adjuvant chemotherapy with or without radiotherapy was 72% as against 47% of those treated with surgery with or without radiotherapy ( p= 0.06). The power of the study was 0.65 for both the DFI and overall survival. The results of the study suggest a possible advantage of epirubicin-based adjuvant chemotherapy in patients with soft-tissue sarcoma at high risk of relapse.

    ABSTRACT: The aim of this study was to investigate the benefit of weekly epirubicin in the treatment of metastatic hormone-resistant prostate cancer. One hundred and forty-eight patients with metastatic hormone-resistant prostate cancer received weekly 30-min intravenous infusions of epirubicin 30 mg m(2) of body surface area. The primary end-point was palliative response, defined as a reduction in pain intensity and an improvement in performance status. The secondary end-points were the duration of the palliative response, quality of life and survival. Fifty-seven (44%) of the 131 evaluable patients met the primary criterion of palliative response after six treatment cycles and 73 (56%) after 12 cycles; the median duration of the response was 9 months (range 1-11). The median global quality of life improved in 52% of the patients after six cycles and in 68% after 12 cycles. The 12- and 18-month survival rates were respectively 56 and 31%, with a median survival of 13+ months (range 1-36). The treatment was well tolerated: grade 3 neutropenia was observed in 8% of the patients, grade 3 anaemia in 7%, and grade 3 thrombocytopenia in 3%. None of the patients developed grade 4 toxicity or congestive heart failure. Weekly epirubicin chemotherapy can lead to a rapid and lasting palliative result in patients with metastatic HRPC, and have a positive effect on the quality of life and survival.
