A potential way to improve the results obtained with the standard carboplatin/cisplatin (CDDP)-paclitaxel treatment regimen in advanced ovarian cancer is to incorporate a modulating agent such as lonidamine (LND). In fact, LND has been shown to revert the resistance to cisplatin and to potentiate cisplatin activity experimental models and in clinical studies. 35 consecutive patients with advanced ovarian cancer, not previously treated with chemotherapy were treated with paclitaxel at a dose of 135 mg/m(2) intravenously (i.v.) on day 1 (in a 3 h infusion) and cisplatin at a dose of 75 mg/m(2) iv on day 2 plus LND orally (p.o.) at a dose of 450 mg/die for 6 consecutive days starting two days before chemotherapy, every 3 weeks for six cycles. Complete plus partial responses were observed in 8 (80%) out of the 10 women with measurable disease. In the 25 patients with evaluable disease, only four clinical progressions were observed (16%). Median progression-free survival (PFS) and overall survival (OS) were 28.5 (95% confidence interval (CI) 22.2-34.8) and 46.5 (95% CI 32.4-60.00) months respectively. Grade 3-4 neutropenia was observed in 9 (26%) patients. Alopecia, nausea and vomiting (Grade 3) were observed in 33 (94%) and 5 (14%) patients, respectively. In conclusion, the combination of CDDP/paclitaxel plus LND is active and tolerable in the treatment of advanced ovarian cancer.

The activity and toxicity of topotecan in women with recurrent cervical cancer are described from a case series of women with recurrent cervical cancer who had measurable disease and were not amenable to cure by surgery or radiation. All patients had prior platinum-based chemotherapy and developed progressive disease. Topotecan was given as 1 mg/m2/day over 30 min for 5 days every 3 weeks until progression of disease or prohibitive toxicity. Between July 1998 and July 1999, 12 patients received a total of 20 cycles of topotecan. Median age was 41 years (range 21-62), and 11 (92%) patients had prior whole pelvic radiation. The mean number of topotecan cycles was 1.5 (median 1, range 1-3). There were two partial responses (16.7%; 95% CI, 2% to 48%), both in prior radiation fields. Five patients required red blood cell transfusions, four had grade II nausea and vomiting, two developed sepsis (one with neutropenia), one developed fever, and one reported hyperpigmentation. There were no treatment-related mortalities. Although topotecan appears to exhibit modest activity in recurrent cervical cancer after radiation and platinum-based therapy, bone marrow toxicity may limit the utility of this regimen without hematopoietic growth factor support.

The purposes of this study were to determine the maximum tolerated dose (MTD), dose-limiting toxicity (DLT), toxicity profile, and antitumor activity of topotecan (TOP) and gemcitabine (GEM) combination therapy when administered to patients with previously treated, advanced, non-small cell lung cancer. Both compounds were administered intravenously over 30 min, with TOP on days 1-5 and GEM on days 1 and 5 only. Nineteen patients were treated with 75 courses at three dose levels. The MTD was 0.75 and 400 mg/m2 for TOP and GEM, respectively, with thrombocytopenia and neutropenia as the DLTs. Partial responses were achieved in 3 of 17 patients (18%) with measurable disease. Six patients (32%) had disease stabilization for at least four courses of treatment. The median survival was 10 months from the initiation of TOP and GEM. This combination was relatively well tolerated and exhibited promising antitumor activity in patients with advanced, previously treated, non-small cell lung cancer.

The purpose of this study was to determine the dose-limiting toxicities and the maximum-tolerated dose (MTD) of weekly administration of paclitaxel in patients with advanced solid tumors. Twenty-six patients with advanced solid tumors were treated with escalated doses of paclitaxel (starting dose 70 mg/m(2)/wk with increments of 10 mg/m(2)/wk) for 4 consecutive weeks every 6 weeks. No intrapatient escalation or growth factor support was allowed. The DLT was exceeded at the dose of 120 mg/m(2)/wk, and the dose-limiting events were grade IV neutropenia and treatment delay because of incomplete hematologic recovery. There was no cumulative myelosuppression. Grade IV neutropenia occurred in four (6%) cycles, and there was one episode of febrile neutropenia. Grade II/III fatigue occurred in 19 (73%) patients, resulting in discontinuation of treatment in 2 of them; grade II neurosensory toxicity and grade II alopecia occurred in 8 (31%) patients each. The MTD, which is also the recommended dose for further phase II studies, was 110 mg/m(2)/wk. Among the 21 patients with bidimensionally measurable disease, 2 (10%) partial responses were observed, both in patients with heavily pretreated advanced breast cancer. The weekly administration of paclitaxel for 4 consecutive weeks in cycles of 6 weeks is a feasible, safe, and active outpatient regimen that merits further evaluation in combination with other anticancer agents.

The primary goal of this phase II study was to determine the efficacy of gemcitabine (Gemzar; Eli Lilly and Company, Indianapolis, IN) plus 5-fluorouracil in patients with pancreatic cancer. Eligibility criteria included nonresectable locally advanced or metastatic pancreatic adenocarcinoma and measurable disease. Gemcitabine at 1,000 mg/m(2) and leucovorin at 20 mg/m(2) were administered intravenously 30 minutes before 5-fluorouracil 600 mg/m(2), weekly for 3 of every 4 weeks. Twenty nine patients were enrolled. The overall response rate was 21% (95% confidence interval: 8% to 40%), consisting of one complete response and five partial responses; 16 patients (55%) had stable disease. Median survival was 8.4 months (95% confidence interval: 2.6 to 14.2), and actuarial 1-year survival was 36%. Neutropenia (grade 3 only) was reported in 3.4% of patients, but was generally of short duration. No thrombocytopenia or evidence of cumulative myelosuppression was observed. The only significant nonhematologic events were grade 3 diarrhea and alopecia (both 3.4%). Gemcitabine plus 5-fluorouracil is active and well tolerated compared with results reported for each of these single agents. Thus, this combination justifies future comparative clinical trials.

In patients with non-colon digestive carcinomas, various schedules and doses of 5-fluorouracil (5-FU) and leucovorin combined with cisplatin (CDDP) have been used extensively. The present study explored the toxicity and activity of a weekly 24-h infusion of high dose 5-FU modulated by high dose leucovorin with bi-weekly CDDP. 59 patients with measurable disease were treated with a weekly infusion of high dose 5-FU (2 or 2.6 g/m2)+leucovorin 500 mg/m2 for 6 weeks and a bi-weekly dose of CDDP (50 mg/m2). All patients had metastatic or locoregionally advanced disease and had a performance status < or =3. All patients were evaluable for toxicity and 58 for response. Toxicity was different according to the schedule of 5-FU. Serious adverse events occurred most frequently when 5-FU was given at a dose of 2.6 g/m2 with a high incidence of grade 3/4 neutropenia (16%) and febrile neutropenia (13%), and led to dose reductions in both CDDP and 5-FU in 13 patients (34%). For patients who started 5-FU at a dose of 2 g/m2, no reduction in 5-FU was required, and only 4 patients required a dose reduction of CDDP (19%). Grade 3/4 neutropenia was seen in 10% of patients of this group and only 1 patient required hospitalisation for febrile neutropenia. Other grade 3/4 toxicities were rare in both groups. Renal toxicity was infrequent and mild and did not require dose adjustments. The overall response rate was 33%; 19 patients achieved a partial responses (PR). No patient had a complete response (CR). The median duration of response was 5.7 months (range 2-24 months) and the median survival was 7.9 months ( range: 1-30, 95% confidence interval (CI): 7-9). The combination of weekly 24-h infusion of high dose 5-FU with leucovorin and bi-weekly cisplatin seems a well-tolerated and active treatment in non-colon digestive carcinomas. A dose of 2 g/m2 of 5-FU seems to be recommended.

The incidence of human epidermal growth factor receptor 2 (HER2) protein overexpression and its prognostic value are not well characterized in patients with prostate cancer. A phase I study was designed to evaluate docetaxel/estramustine plus trastuzumab, a humanized monoclonal antibody that binds to the HER2 receptor, in patients with metastatic androgen-independent prostate cancer (AIPC). HER2 positivity was not required because safety was the primary endpoint. Patients received oral estramustine 280 mg three times daily (days 1 to 5); docetaxel, 70 mg/m(2) intravenously (day 2); and trastuzumab, 2 mg/kg intravenously (days 2, 9, and 19), every 21 days until the disease progressed or toxicity became unacceptable. This regimen was well tolerated among the first 13 treated patients. Grade 4 neutropenia was seen in 10% of administered cycles. There were two episodes of febrile neutropenia and two thrombembolic events. Of the 13 patients evaluable for prostate-specific antigen (PSA) response, nine (69%) experienced a decrease in PSA level of >50%. Two (33%) of six patients with measurable disease had objective responses, and one complete response was seen on bone scan. Docetaxel/estramustine/trastuzumab appears to be a safe combination when used in the treatment of metastatic AIPC. The response data are too preliminary for speculation about the relative benefits of this 3-drug regimen compared with the combination of only docetaxel and estramustine in this clinical setting.

To evaluate activity and toxicity of a non platinum-based triplet including Gemcitabine, Ifosfamide and Navelbine (GIN) in advanced NSCLC. Stage IIIB/IV NSCLC patients with WHO PS < 2 and bidimensionally measurable disease entered the study. Gemcitabine 1000 mg/sqm day 1 and 1000-800 mg/sqm day 4, Ifosfamide 3 g/sqm day 1 (with Mesna), Navelbine 25 mg/sqm day 1 and 25-20 mg/sqm day 4 were administered intravenously every 3 weeks. Objective responses (ORs) were evaluated every 2 courses: a maximum of 6 courses were administered in responding patients. According to Simon's optimal two-stage design more than 18 ORs out of 54 patients were required to establish the activity of this regimen. Fifty patients entered the study. Main characteristics of the 48 evaluated patients were: median age 63 years, ECOG performance status 0 = 65%, stage IV disease 79% and non-squamous histology 71%. The total number of courses administered was 200, median per patient 4 (range 1-6). Toxicities were evaluated according to WHO criteria: neutropenia grade 3-4 occurred in 47% of the courses; thrombocytopenia grade 3-4 in 6.6%; anaemia grade 3 in 3.5%. Twelve episodes of febrile neutropenia were reported and three patients required hospital admission. No toxic death was reported. Non-haematological toxicity, including skin rash, alopecia and fatigue, were generally. Twenty-five ORs (1 complete response and 24 partial responses) were obtained for a response rate of 52% (95% CI: 37.4-66.5%). One-year survival was 46.5%. This non-platinum-based outpatient triplet showed promising activity against NSCLC with myelosuppression, in particular neutropenia, being dose-limiting. The GIN regimen may represent a valuable alternative to standard platinum-based doublets and triplets in the treatment of advanced NSCLC and further studies with this platinum-free combination are warranted.

We report on two randomized trials performed in the USA and Europe, which compared methotrexate and nolatrexed as treatment for patients with recurrent head and neck cancer. Eligibility criteria included: histologically confirmed squamous-cell carcinoma, measurable disease, adequate hematological, renal and hepatic functions, failure of a first-line chemotherapy, and informed consent. Methotrexate 40 mg/m2 was weekly given by short infusion, and nolatrexed 725 mg/m2 per day was administered as a five-day continuous infusion, every three weeks. A total of 139 patients (63 in the USA. 76 in Europe) were randomized based on a ratio of 2/1: 93 and 46 received nolatrexed and methotrexate, respectively. Patient characteristics included 115 males and 24 females; median age 60 years. In the nolatrexed arm, the following grade 3-4 toxicities occurred: neutropenia (29.9%) with 3.1% of febrile neutropenia, mucositis (33.3%), and vomiting (10.3%). In the MTX arm, the grade 3-4 toxicities were neutropenia (7.1%) and mucositis (6.9%). There was no difference in activity between the nolatrexed and the methotrexate treatment: 3.3% and 10.8% of objective responses, 1.9 versus 1.5 months of disease-free progression and 3.5 versus 3.7 months of overall survival, respectively. Nolatrexed has demonstrated a similar activity to methotrexate.

In a phase I study we demonstrated the feasibility of a bi-weekly combination of paclitaxel 180 mg x m(-2) with cisplatin 60 mg x m(-2). In this study we further assessed toxicity and efficacy of this schedule in the treatment of advanced cancer of the oesophagus or the gastro-oesophageal junction. Patients received paclitaxel 180 mg x m(-2) administered over 3 h followed by a 3-h infusion of cisplatin 60 mg x m(-2). Patients were retreated every 2 weeks unless granulocytes were <0.75x10(9) or platelets <75x10(9). Patients were evaluated after three and six cycles and responding patients received a maximum of eight cycles. Fifty-one patients were enrolled into the study. The median age was 56 years (range 32-78). WHO performance status were: 0 (19 patients); 1 (29 patients); 2 (three patients). All patients received at least three cycles of chemotherapy and all were evaluable for toxicity and response. Haematological toxicity consisted of uncomplicated neutropenia grade 3 in 39% and grade 4 in 31% of patients. Five patients (10%) were hospitalised, three patients because of treatment related complications and two patients because of infections without neutropenia. Sensory neurotoxicity was the predominant non-haematological toxicity; grade 1 and 2 neurotoxicity was observed in 43 and 20% of patients, respectively. Response evaluation in 51 patients with measurable disease: complete response 4%, partial response 39%, stable disease 43% and progressive disease in 14% of the patients. The median duration of response was 8 months. The median survival for all patients was 9 (range 2-29+) months and the one-year survival rate was 43%. Four patients who received additional local treatment (two patients surgery and two patients radiotherapy) are still disease free after a follow-up of 20-29 months. This bi-weekly treatment of paclitaxel and cisplatin is well tolerated by patients with advanced oesophageal cancer. The toxicity profile of this regimen compares favourable to that of previously used cisplatin- and paclitaxel-based regimens. Trials are underway evaluating this bi-weekly regimen in a neo-adjuvant setting.
