RESUMEN
To investigate whether a relationship between chemotherapy-associated adverse events and treatment efficacy exists, we have analysed the toxicity, objective response and survival data of 303 patients with advanced colorectal cancer. Patients were divided into two groups: the first with beneficial effect (I, n = 245), and the second with progressive disease (II, n = 58). Differences in terms of incidence rates, type and severity of ad verse events were analysed with univariate and multivariate models. The median number of side effects in group I was 6 vs 4 in group II (OR=1.342; P= 0.0001). An inverse correlation between disease control and treatment tolerance was confirmed when side effects were analysed according to severity and type of treatment-associated toxicities (haematological: P = 0.0005 vs nonhaematological P = 0.0001). When median survival was analysed according to the number of adverse events, it was 10 (95% CI, 3-7), 16 (14-18), and 18 (16-20) months in case of 0-1, 2-5, and > or =6 adverse events, respectively (P = 0.01). In conclusion, the results of this analysis suggest that occurrence of side effects during chemotherapy in advanced colorectal cancer is an independent and reliable prognostic indicator for response and survival.

BACKGROUND: Patients with advanced biliary tract carcinoma face a particularly dismal prognosis, and no standard palliative chemotherapy has yet been defined. Among several different single agents, mitomycin C and, more recently, the oral fluoropyrimidine capecitabine and the nucleoside analogue gemcitabine, have been reported to exert antitumour activity. In view of a potential drug synergy, the present randomised phase II trial was initiated. The aim was to investigate the therapeutic efficacy and tolerance of mitomycin C (MMC) in combination with gemcitabine (GEM) or capecitabine (CAPE) in previously untreated patients with advanced biliary tract cancer. PATIENTS AND METHODS: A total of 51 patients were entered in this study and randomly allocated to treatment with MMC 8 mg/m2 on day 1 in combination with GEM 2000 mg/m2 on days 1 and 15 every 4 weeks, or MMC 8 mg/m2 on day 1 plus CAPE 2000 mg/m2/day on days 1-14, every 4 weeks. In both arms, chemotherapy was administered for a total of 6 months unless progressive disease occurred earlier. RESULTS: Pretreatment characteristics were well balanced between the two treatment arms. The overall independent review committee-confirmed response rate among those treated with MMC + GEM was 20% (five of 25) compared with 31% (eight of 26) among those treated with MMC + CAPE. Similarly, median progression-free survival (PFS; 4.2 versus 5.3 months) and median overall survival (OS; 6.7 versus 9.25 months) tended to be superior in the latter combination arm. Chemotherapy was fairly well tolerated in both arms, with a comparably low rate of only grade 1 and 2 non-haematological adverse reactions. Also, only four (17%) patients in both treatment arms experienced grade 3 leukocytopenia, and three (13%) and four (17%) had grade 3 thrombocytopenia in the MMC + GEM and MMC + CAPE arm, respectively. CONCLUSIONS: The results of this study indicate that both combination regimens are feasible, tolerable and clinically active. The MMC + CAPE arm, however, seems to be superior in terms of response rate, PFS and OS, and should therefore be selected for further clinical investigation in advanced biliary tract cancer.

BACKGROUND: Treatment with oxaliplatin plus raltitrexed has demonstrated an encouraging therapeutic index in patients with advanced colorectal cancer and malignant pleural mesothelioma. The aim of this multi-institutional study was to determine the antitumor potential of this combination in patients with metastatic gastric cancer failing prior palliative first-line chemotherapy, and to reconfirm its favorable toxicity profile. PATIENTS AND METHODS: 21 patients with metastatic gastric cancer, who progressed while on or within 6 months after discontinuing palliative first-line chemotherapy, participated in this study. They received raltitrexed 3,0 mg/m(2) and oxaliplatin 130 mg/m(2) both given intravenously on day 1 every 3 weeks. RESULTS: One patient achieved a partial response, 6 had stable disease, and 14 patients progressed. Median progression-free and overall survival from the onset of salvage chemotherapy was 2.0 and 4.5 months, respectively. Hematologic adverse reactions, specifically neutropenia and anemia were common, though generally mild to moderate with only 3 patients experiencing grade 3/4 toxicity. The most frequent non-hematologic adverse events included nausea/emesis, asthenia, and transient elevation of liver functional parameters, again with grade 3 symptoms occurring only in a minority of patients. CONCLUSION: Despite reproducibility of a favorable toxicity profile of oxaliplatin + raltitrexed, our data suggest that this combination regimen has no substantial antitumor activity in patients with progressive, chemotherapeutically pretreated metastatic gastric cancer.

There is no established second-line treatment for advanced pancreatic cancer after gemcitabine failure. In view of the urgent need for such therapy, and since preclinical and phase I clinical data suggest an encouraging, potentially synergistic activity between raltitrexed and irinotecan, the present randomised phase II study was initiated. A total of 38 patients with metastatic pancreatic adenocarcinoma, who progressed while receiving or within 6 months after discontinuation of palliative first-line chemotherapy with gemcitabine, were enrolled in this study. They were randomised to 3-weekly courses of raltitrexed 3 mg x m(-2) on day 1 (arm A) or irinotecan 200 mg x m(-2) on day 1 plus raltitrexed 3 mg x m(-2) on day 2 (arm B). The primary study end point was objective response, secondary end points included progression-free survival (PFS) and overall survival (OS), as well as clinical benefit response in symptomatic patients (n=28). In the combination arm, the IRC-confirmed objective response rate was 16% (three out of 19 patients had a partial remission; 95% CI, 3-40%), which was clearly superior to that in the comparator/control arm with raltitrexed alone, in which no response was obtained. Therefore, the trial was already stopped at the first stage of accrual. Also, the secondary study end points, median PFS (2.5 vs 4.0 months), OS (4.3 vs 6.5 months), and clinical benefit response (8 vs 29%) were superior in the combination arm. The objective and subjective benefits of raltitrexed+irinotecan were not negated by severe, clinically relevant treatment-related toxicities: gastrointestinal symptoms (42 vs 68%), partial alopecia (0 vs 42%), and cholinergic syndrome (0 vs 21%) were more commonly noted in arm B; however, grade 3 adverse events occurred in only three patients in both treatment groups. Our data indicate that combined raltitrexed+irinotecan seems to be an effective salvage regimen in patients with gemcitabine-pretreated pancreatic cancer. The superior response activity, PFS and OS (when compared to raltitrexed), as well as its tolerability and ease of administration suggest that future trials with this combination are warranted.

BACKGROUND: Gemcitabine is an active antitumor agent in the treatment of advanced pancreatic cancer, and has shown potential synergistic activity with the oral fluoropyrimidine capecitabine in previous phase I/II trials. Based on this background and in order to define the therapeutic potential and tolerance of this combination more precisely, the present randomized multicenter phase II trial was initiated. PATIENTS AND METHODS: We prospectively randomized 83 patients to treatment with biweekly gemcitabine 2,200 mg/m(2) given as a 30 min intravenous infusion on day 1, or the same treatment plus oral capecitabine 2,500 mg/m(2) given from days 1 to 7. In both arms, chemotherapy was administered for a duration of 6 months unless there was prior evidence of progressive disease. The efficacy of the two treatment arms was evaluated according to standard criteria, i.e. objective response, progression-free survival (PFS) and overall survival (OS), as well as by analysis of clinical benefit response. RESULTS: The overall objective response rate among the 42 patients treated with gemcitabine alone was 14% compared with 7/41 (17%) among those treated with the combination arm. Similar to response rates, there was no apparent difference between the two groups in terms of median PFS (4.0 versus 5.1 months) and median OS (8.2 versus 9.5 months) in the gemcitabine and combination arm, respectively. Of 61 patients with tumor-related symptoms, who were considered evaluable for clinical benefit response, 10/30 (33%) and 15/31 (48.4%) experienced significant palliation in the gemcitabine and combination arm, respectively. Chemotherapy was well tolerated in both arms with only four versus six patients experiencing WHO grade 3 symptoms. Apart from the occurrence of hand-foot syndrome in 10 patients, no major increase in incidence and/or degree of adverse reactions was noted in the combination arm. CONCLUSIONS: Results of this trial suggest a fairly good therapeutic index for the combination of biweekly high-dose gemcitabine and capecitabine for the treatment of advanced pancreatic cancer. Despite a somewhat superior clinical benefit response rate, no advantage over single-agent gemcitabine, however, was noted in terms of objective efficacy parameters.

AIMS: Palliative attempts have traditionally led treatment of gallbladder cancer but resection offers the only chance for long-term survival. This study investigates the impact of surgery with curative intent in gallbladder cancer treatment and evaluates prognostic factors for survival. METHODS: Two hundred and sixty-seven patients were admitted for surgical therapy. Sixty received resection with curative intent and form the basis of this analysis. RESULTS: R0 resection (n=45) was a highly significant independent survival predictor (P<0.001). All 5-year survivors (n=10) had tumour-free resection margins. Early T stage (P=0.017) and highly differentiated cancer (P=0.008) had a significant better outcome. Nodal spreading increased by local tumour extension and lymphatic involvement decreased patient survival (P=0.018). Patients' age (>75 years) was without influence on long-term survival. CONCLUSIONS: Long-term survival is possible both in elderly patients and in advanced cancer.

BACKGROUND: Both oxaliplatin and irinotecan have demonstrated antitumor activity in pretreated colorectal cancer; experimental and early clinical data suggest that these two drugs may act synergistically. The aim of this study was to document the therapeutic index of a biweekly combination regimen in patients with metastatic colorectal cancer failing prior palliative first-line chemotherapy with raltitrexed. PATIENTS AND METHODS: In this study 27 patients with metastatic colorectal cancer were analyzed, who progressed while on or within 6 months after discontinuation of palliative first-line chemotherapy with raltitrexed. They received oxaliplatin 85 mg/m(2) and irinotecan 150 mg/m(2) both given on days 1 and 15 every 4 weeks. RESULTS: The confirmed overall response rate was 37% (95% confidence interval, 19.4-57.7%), including 2 complete and 8 partial remissions. 12 additional patients (44.4%) had stable disease, and in only 5 cases (18.5%) disease progression was not influenced by chemotherapy. The median progression-free survival for all 27 patients was 8 months (range, 1-16+ months), and 16 patients (59%) are still alive after a median follow-up time of 12.5 months. Hematologic adverse reactions, specifically leukocytopenia and neutropenia, were common though generally mild to moderate with grade 4 toxicity occurring in only 2 cases. The most frequent non-hematologic adverse events included gastrointestinal symptoms; severe nausea/emesis and diarrhea, however, were noted in only 2 and 3 patients, respectively. CONCLUSIONS: Our data suggest that the described biweekly combination regimen of oxaliplatin and irinotecan has substantial antitumor activity in patients with progressive, raltitrexed-pretreated metastatic colorectal cancer. Because of its favorable toxicity profile, further evaluation of this combination seems warranted.

A phase II trial was performed to determine the antitumour efficacy and tolerance of combined paclitaxel and cisplatin with or without hematopoetic growth factor support in patients with advanced gastric cancer. Forty-five patients with histologically confirmed metastatic gastric cancer were entered in this trial. Treatment consisted of 2-weekly courses of paclitaxel 160 mg per m2 and cisplatin 60 mg per m2 both given on day 1. Depending on absolute neutrophil counts on the days of scheduled chemotherapeutic drug administration (1000-2000 per microl), a 5-day course of human granulocyte colony-stimulating factor 5 microg x kg(-1) per day was given subcutaneously; in addition, if haemoglobin was <12.0 mg dl(-1), erythropoietin 10 000 IU was administered subcutaneously three times per week. The confirmed overall response rate (intent-to-treat) was 44%, including five complete (11%) and 15 partial remissions (33%). Twelve patients had stable disease (27%), 11 (24%) progressed while on chemotherapy, and two patients were not evaluable. The median time to response was 3 months, the median time to progression 7.0 months, and the median survival time was 11.2 months with 12 patients currently alive. Haematologic toxicity was common, though WHO grade 4 neutropenia occurred in only five patients (11%). Apart from total alopecia in 16 patients (36%), severe non-haematologic adverse reactions included grade 3 peripheral neuropathy in six (13%) and anaphylaxis in two patients. In addition, there was one patient each who experienced grade 3 emesis, diarrhea, and infection, respectively. Our data suggest that the combination of paclitaxel and cisplatin with or without G-CSF and/or erythropoietin has promising therapeutic activity in patients with advanced gastric cancer.

INTRODUCTION: There are various options for the treatment of gallbladder carcinoma; however, only radical resection offers a chance for prolonged survival. METHODS: The aim of this study was to analyze retrospectively patients suffering from gallbladder carcinoma in a central hospital in Austria. From 1986 to 1999, 77 patients were treated in this surgical department. The median age of the patients was 71.3 years. RESULTS: In 28 patients the cancer was resected and 22 persons underwent palliative surgery. An explorative laparotomy was performed in 16 patients. Eleven patients had no surgical therapy, 10 persons received gemcitabine or a combination chemotherapy regimen consisting of leucoverin, 5-fluorouracil and mitomycin C. The median survival of patients without chemotherapy following radical resection (n = 15) was 10.7 months (one patient with metastatic cancer was excluded) and for patients with tumor remaining margins (n = 8) 3.2 months (P = 0.023). Without chemotherapy the median patient survival following palliative resection (n = 17) and explorative laparotomy (n = 15) was 1.5 months and 2.1 months. The median survival without surgical therapy was 1.6 months. Chemotherapy was administered to four of the resected patients (median survival 16.5 months), in five patients following palliative surgery and in one patient after explorative laparotomy (median survival 4.3 months) (P = 0.034). In a multivariate analysis, tumor resection (P = 0.034) and tumor-free resection margins (P = 0.025) proved to be the most important determinants for patient survival. CONCLUSION: Tumor resection is the most important factor for a prolonged patient survival. Following radical resection in an early tumor stage and combining this approach with an established chemotherapy, patient survival could be increased significantly.

BACKGROUND: A multicenter phase II trial was initiated to investigate the efficacy and tolerance of a dose-fractionated administration schedule of irinotecan in patients with advanced colorectal cancer pre-treated with fluoropyrimidine/ oxaliplatin-based first-line combination chemotherapy. PATIENTS AND METHODS: 38 patients with metastatic colorectal cancer, who progressed while receiving or within six months after withholding systemic chemotherapy with oxaliplatin in combination with 5-fluorouracil/leucovorin or the specific thymidilate synthase inhibitor raltitrexed were enrolled in this study. Treatment consisted of irinotecan 175 mg/m2 given on days 1 and 10. Courses were repeated every three weeks for a total of six courses unless prior evidence of progressive disease. RESULTS: The overall objective response rate was 21% for all 38 patients (95% confidence interval (95% CI): 9.6% to 37.4%). Stable disease was noted in 19 patients (50%), whereas the tumour progressed in 11 (29%). The median progression-free survival was 4.8 months (range 1.5 to 10.5). After a median follow-up time of 10 months, 21 patients (55%) are still alive. Treatment was fairly well tolerated with only 9 of 38 patients (24%) experiencing grade 3 or 4 neutropenia. Similarly, nonhaematologic adverse reactions were generally mild; grade 3 toxicities included late-onset diarrhoea in 2 (5%), alopecia in 5 (13%), and infection in 1 case (3%), respectively. CONCLUSIONS: Our data suggest that this dose-fractionated irinotecan monotherapy schedule has substantial antitumour activity in patients with flupropyrimidine/oxaliplatin-based pre-treated colorectal cancer. Because of its favourable toxicity profile when compared to previous experiences with the European standard schedule of 350 mg/m2 every three weeks, further evaluation of this modified regimen seems warranted.

BACKGROUND: To evaluate the efficacy and tolerance of combined raltitrexed and oxaliplatin in patients with advanced colorectal cancer pretreated with fluoropyrimidine leucovorin-based chemotherapy. PATIENTS AND METHODS: Thirty-six patients with metastatic colorectal cancer, who progressed while receiving or within six months after withholding palliative chemotherapy with fluoropyrimidines leucovorin +/- irinotecan, participated in this study. Treatment consisted of oxaliplatin 130 mg/m2 and raltitrexed 3.0 mg/m2 both given on day 1 every three weeks for a total of eight courses unless prior evidence of progressive disease. RESULTS: The overall objective response rate was 33.3% for all 36 evaluable patients (95% confidence interval (CI): 18.6%-51%). Seventeen additional patients (47.2%) had stable disease, and only seven (19.5%) progressed. The median progression-free survival was 6.5 months (range 1.2-14.0). After a median follow-up time of 12 months, 23 patients (63.8%) are still alive. The tolerance of treatment was acceptable with only 8 of 36 patients (22%) experiencing grade 3 or 4 neutropenia. Grade 3 non-haematological adverse reactions included peripheral sensory neuropathy in three, asthenia in one, diarrhea in two, and clinically insignificant increase in serum transaminases in two patients, respectively. CONCLUSIONS: Our data suggest that the combination of oxaliplatin and raltitrexed has substantial antitumour activity in patients with progressive fluoropyrimidine leucovorin + irinotecan pretreated colorectal cancer. Because of its favorable toxicity profile and convenient three-weekly outpatient administration schedule, further evaluation of this regimen seems warranted.

To assess whether the lung resistance protein (LRP) is of clinical significance in colorectal carcinomas, we immunohistochemically determined LRP expression of colorectal carcinoma specimens (n = 68) by means of the monoclonal antibody LRP-56 and compared this expression with clinical parameters. LRP expression was negative in 7 (10%), low in 36 (52%) and high in 25 (38%) carcinomas. LRP expression was independent of histological grade, tumor size, lymph node involvement and distant metastasis. Survival of the patients with LRP-positive tumors was similar to the survival of patients with LRP-negative tumors. However, patients with high LRP expression in their carcinomas had a prolonged survival. Thus LRP is frequently expressed in colorectal carcinomas and high expression might indicate improved survival.

BACKGROUND: Patients with advanced biliary tract carcinoma face a dismal prognosis as no effective palliative therapy has been defined. The aim of the present phase II investigation was to evaluate the therapeutic efficacy and tolerance of a two-weekly high-dose gemcitabine regimen in this patient population. PATIENTS AND METHODS: Thirty-two consecutive patients with locally unresectable or metastatic biliary tract cancer were enrolled in this multicenter phase II trial. Treatment consisted of gemcitabine 2200 mg/m2 given as a 30-min intravenous infusion every two weeks for a duration of six months unless there was prior evidence of progressive disease. RESULTS: After a median number of 12 treatment courses, 7 of 32 (22%) patients had a partial response that lasted for a median duration of 6.0 months (range 3.5-10.0). Fourteen additional patients (44%) had stable disease, whereas eleven patients (34%) progressed despite therapy. The median time to progression was 5.6 months (range 1.8-13.0); median survival time was 11.5 months (range 3.0-24.0), and the probability of surviving beyond 12 months was 44%. The tolerance of treatment was remarkable with only two patients each experiencing grade 3 leukocytopenia, granulocytopenia and/or thrombocytopenia, and one patient had grade 3 anaemia. Similarly, nonhaematologic side effects were infrequent, and generally mild to moderate. CONCLUSIONS: Two-weekly high-dose gemcitabine seems to represent a potentially effective, safe and well-tolerated regimen for the palliative treatment of patients with advanced biliary tract cancer.

BACKGROUND: Oxaliplatin and raltitrexed both are active anticancer agents in the treatment of patients with advanced colorectal carcinoma: They have different mechanisms of action and toxicity profiles and have shown at least additive effects in experimental and preliminary clinical studies. The aim of this disease oriented Phase I-II study was to determine the maximum tolerated dose (MTD), the dose-limiting toxicities (DLT), and the objective response rate of this combination in patients with advanced colorectal carcinoma. METHODS: Between April 1998 and March 1999, 69 patients with measurable metastatic colorectal carcinoma who previously were unexposed to palliative chemotherapy were enrolled. In the Phase I part of the study, 27 patients were treated with 3-weekly courses of a fixed dose of raltitrexed (3 mg/m(2) given as a 15-minute intravenous infusion) followed by a 2-hour infusion of oxaliplatin, which was escalated in consecutive cohorts of three to six patients from 85 mg/m(2) to 100 mg/m(2), 120 mg/m(2), 130 mg/m(2), and 140 mg/m(2). After having defined the toxic dose, 42 additional patients were entered at one dose level below to define the therapeutic index of this combination more precisely. RESULTS: In the Phase I part of the study, during the first three dose levels, only one patient each experienced DLT (Grade 3 increase in transaminases, diarrhea, and stomatitis); at level 4, two of the first six patients entered had Grade 3 neutropenic infection or peripheral neurotoxicity, whereas dose level 5 (oxaliplatin 140 mg/m(2)) constituted the toxic dose with three of three patients experiencing DLT (Grade 3 asthenia, transient amaurosis, and diarrhea with Grade 4 neutropenia). Externally reviewed objective responses were noted in 9 of these 27 patients (33%), and stable disease occurred in 12 patients (44.4%). Among the 42 patients who were treated subsequently at the MTD level (Phase II portion), 20 patients (47.6%) responded (95% confidence interval, 32-62.6%), and 21 patients (50%) had stable disease. Their median progression free survival was 9.0 months, and the median overall survival, with 42 patients (67%) currently alive, is > 14.5 months. Treatment tolerance at the MTD was acceptable, with only 9 of 42 patients (21%) experiencing Grade 3-4 neutropenia; Grade 3 nonhematologic adverse reactions included increase in serum transaminases in 6 patients, peripheral neuropathy in 3 patients, diarrhea in 3 patients, and both stomatitis and emesis in only 1 patient each. CONCLUSIONS: The described objective response and toxicity data, which are in agreement with preliminary results of other Phase I-II studies, support the promising therapeutic potential of this combination in the treatment of patients with advanced colorectal carcinoma. Due to its substantial antitumor activity, tolerance (at the recommended MTD level), and convenient 3-weekly outpatient administration schedule, further evaluation of this regimen seems warranted.

PURPOSE: A multicenter phase II trial was performed to investigate the efficacy and tolerance of docetaxel, vinorelbine with or without recombinant human granulocyte colony-stimulating factor (G-CSF) in patients with metastatic breast cancer. PATIENTS AND METHODS: Between February 1998 and March 1999, 57 patients participated in this trial. Forty-two patients received this combination as first-line and 15 patients as second-line chemotherapy, including 10 patients who had failed anthracyclines. Therapy consisted of vinorelbine 30 mg/m(2) on days 1 and 15 and docetaxel 30 mg/m(2) on days 1, 8, and 15 every 4 weeks. Depending on the absolute neutrophil counts on the day of scheduled chemotherapeutic drug administration, a 5-day course of G-CSF 5 microg/kg/d was given. RESULTS: The overall response rate was 64.3% (95% confidence interval, 48.1% to 78.4%) in patients receiving docetaxel plus vinorelbine as first-line chemotherapy, including eight complete (19%) and 19 partial remissions (45.3%); 11 patients (26.2%) had disease stabilization, and only four (9.5%) progressed. Second-line treatment with this regimen resulted in eight (53.3%) of 15 objective responses, four had stable disease, and three had progressive disease. The median time to progression was 12 months in the first-line and 9.8 months in the second-line setting, respectively. After a median follow-up time of 18 months, 38 patients (65%) were still alive with metastatic disease. Myelosuppression was commonly observed; World Health Organization grade 3 or 4 neutropenia both occurred in 18 patients (32%) and was complicated by septicemia in four cases; grade 3 or 4 thrombocytopenia was seen in two patients (4%), and grade 3 anemia was seen in only one patient (2%). Severe (grade 3) nonhematologic toxicity, except for alopecia, was rarely observed and included nausea/vomiting in two patients (4%), and stomatitis, peripheral neuropathy, and skin toxicity each in one patient. CONCLUSION: Our data suggest that docetaxel and vinorelbine with or without G-CSF is an effective and fairly well tolerated regimen for the treatment of advanced breast cancer. It might be particularly useful in patients previously exposed to adjuvant or palliative anthracyclines and/or alkylating agents.

PURPOSE: A phase II study was performed to investigate the efficacy and tolerance of alternating docetaxel and epirubicin/cyclophosphamide plus recombinant human granulocyte colony-stimulating factor (G-CSF) in patients with advanced breast cancer who failed previous non-anthracycline/taxane-containing palliative chemotherapy. PATIENTS AND METHODS: Between November 96 and June 98, a total of 45 patients participated in this trial. Chemotherapy consisted of docetaxel 100 mg/m2 given as a 1-h infusion on day 1, and epirubicin 100 mg/m2 plus cyclophosphamide 800 mg/m2 both administered on day 21. G-CSF 5 microg/kg/day was given subcutaneously from days 22-28 during each cycle. Treatment courses were repeated every 42 days for a total of three courses unless prior evidence of progressive disease. RESULTS: The overall response rate was 57.8% (95% confidence interval, 42.1-72.3%), including seven complete (15.5%) and 19 partial remissions (42.3%); nine patients (20%) had stabilization of disease and 10 (22.3%) progressed. The median time to treatment failure was 7.0 months (range 1.5-26.0), and the median overall survival time 15.0 months (range 2.0-37.0+) with 12 patients (27%) currently still alive with metastatic disease. Myelosuppression was commonly observed with WHO grade 3/4 neutropenia in 20 patients (44%) complicated by septicemia in five (11%). Severe nonhematologic toxicity included stomatitis in five patients (11%), skin and peripheral neurotoxicity each in one patient; alopecia was seen in all 45 patients with complete hair loss in 26 (58%). CONCLUSIONS: Our data suggest that alternating docetaxel and epirubicin/cyclo-phosphamide plus G-CSF is an effective and tolerable second-line combination regimen for the treatment of advanced breast cancer.

BACKGROUND: Although the novel cytidine analog gemcitabine has shown superior antitumor activity compared with weekly bolus 5-fluorouracil in patients with advanced pancreatic carcinoma, further improvements of therapeutic results are warranted. The current Phase II study was initiated to investigate whether this might be achieved by dose intensification. METHODS: Between August 1997 and September 1998, 43 consecutive patients with metastatic pancreatic adenocarcinoma were enrolled in this multicenter Phase II trial. Patients received 4 weekly courses of gemcitabine 2200 mg/m((2)) given as intravenous infusion during 30 minutes on Days 1 and 15 for a duration of 6 months unless there was prior evidence of progressive disease. The efficacy of treatment was assessed according to standard criteria, i.e., objective response, progression free survival, and overall survival, as well as by analysis of clinical benefit response (defined as >/= 50% reduction in pain intensity, >/= 50% reduction in daily analgesic consumption, and/or >/= 20 point improvement in Karnofsky performance status that was sustained for >/= 4 consecutive weeks). RESULTS: Of 43 patients evaluable for objective response, 1 achieved complete and 8 partial remissions, for an overall response rate of 21% (95% confidence interval, 10-36%); 18 additional patients (42%) had stable and 16 (37%) progressive disease. The median time to progression was 5.3 months. Median survival was 8.8 months, and the probability of surviving beyond 12 months was 26.3%. Of 36 patients with tumor-related symptoms who were considered evaluable for clinical benefit response, 16 (44%) experienced significant palliation. The median time to achieve a clinical benefit response was 6 weeks, and its median duration was 27 weeks. Chemotherapy was well tolerated, with leukopenia/granulocytopenia representing the most common side effect. Gastrointestinal and other subjective toxicities were infrequent and generally mild. CONCLUSIONS: Biweekly high dose gemcitabine seems to represent a safe, tolerable, and effective regimen for the palliative treatment of patients with advanced pancreatic carcinoma.

The aim of the study was to evaluate the effectiveness and safety of a combined treatment modality including systemic chemotherapy with 5-fluorouracil (FU), leucovorin, cisplatin and external beam radiotherapy in patients with locally advanced pancreatic cancer. Systemic chemotherapy consisted of FU 400 mg m(-2) and leucovorin 20 mg m(-2) both given as intravenous bolus injection on days 1-4, plus cisplatin 20 mg m(-2) administered as 90-min infusion on days 1-4. Treatment courses were repeated every 4 weeks x 6 unless prior evidence of progressive disease. Radiation therapy using megavolt irradiation of > or = 6 MV photons with a 3- or 4-field technique was delivered during the second and third chemotherapy course, that was reduced in dose by 25%. Between October 1994 and July 1996, a total of 38 patients were entered onto this trial, all of whom were assessable for toxicity and survival. Eighteen of these (47%) had objective remissions to combined radiochemotherapy, including four CR (11%), 13 (34%) had stable disease and seven patients (18%) showed tumour progression during treatment. The median progression-free interval of the entire study population was 10 months (range 3-32), and median overall survival was 14.0 months (range 3-45+ months); 53% of all patients were alive at 12 months, and 18% of patients were alive at 24 months respectively. Severe haematological side-effects comprised neutropenia in 18%, thrombocytopenia in 8% and anaemia in 11%. The most frequent non-haematological side-effects were nausea/vomiting (WHO grade 3: 18%), and diarrhoea (grade 3: 13%). This combined radiochemotherapy regimen was tolerable and effective in patients with locally advanced pancreatic cancer. Since therapeutic results, in fact, compare favourably with other series, including surgical treatment of potentially resectable tumours, further evaluation of combined treatment modalities in the neoadjuvant setting seems warranted.

PURPOSE: A phase II trial was performed to investigate the efficacy and tolerance of gemcitabine, vinorelbine, and recombinant human granulocyte colony-stimulating factor (G-CSF) in advanced breast cancer. PATIENTS AND METHODS: Between April 96 and August 97, 60 patients entered this trial. Forty-five patients were previously untreated and 15 patients had failed previous palliative chemotherapy with (n = 10) or without anthracyclines (n = 5). Therapy consisted of gemcitabine 1000 mg/m2 on days 1 + 15 + 21 and vinorelbine 40 mg/m2 on days 1 + 21, both diluted in 250 ml saline and infused over 30 min. G-CSF was administered at 5 microg/kg/day subcutaneously from days 2-6 and 22-26. Courses were repeated every 5 weeks. Treatment was continued in case of response or stable disease until a total of six courses. RESULTS: The overall response rate was 55.5% for patients who had not received prior palliative chemotherapy (95% confidence interval, 40%-70.3%), including 5 CR (11.1%) and 20 PR (44.4%); 12 patients (27%) had stable disease (SD), and 8 (18%) progressed. Second-line treatment with this regimen resulted in 6/15 (40%) objective remissions, 5 had SD, and 4 PD. The median time to progression was 9.5 months (range, 1.5-28) in previously untreated patients, and 7.0 months (range, 2-23) in those who had failed prior chemotherapy. After a median follow-up time of 15 months, 44 patients (73%) are still alive with metastatic disease. Myelosuppression was commonly observed, though WHO 3 and 4 neutropenia occured in only 9 (15%) and 2 patients (3%), and was never complicated by septicaemia; grade 3 anemia was noted in 2 patients. Severe (WHO grade 3) nonhematologic toxicity was rarely observed, and included nausea/emesis in 3 and constipation in 2 patients. CONCLUSIONS: Our data suggest that gemcitabine and vinorelbine plus G-CSF is an effective and tolerable first- as well as second-line combination regimen for treatment of advanced breast cancer.

Although the novel cytidin analogue gemcitabine has shown superior anti-tumour activity than 5-fluorouracil in advanced pancreatic cancer, further improvements of therapeutic results are warranted. This goal might be achieved by combining gemcitabine with other active drugs. This trial evaluated the efficacy and tolerance of such a combination regimen with epirubicin and granulocyte colony-stimulating factor (G-CSF) in patients with metastatic disease. Seventy patients with metastatic pancreatic adenocarcinoma were enrolled in this multicentre trial. Patients received 4-weekly courses of a combination regimen consisting of epirubicin 60 mg m(-2) given as intravenous bolus injection on day 1, gemcitabine 1000 mg m(-2) infused over 30 min on days 1, 8 and 15, and G-CSF administered at 5 microg kg(-1) day(-1) subcutaneously from days 2-6 during each cycle. The efficacy of treatment was assessed by conventional measures, i.e. objective response, progression-free and overall survival, as well as by analysis of clinical benefit response (defined as > or = 50% reduction in pain intensity, > or = 50% reduction in daily analgesic consumption, and/or > or = 20-point improvement in Karnofsky performance status that was sustained for > or = 4 consecutive weeks). Of 66 patients evaluable for objective response, one achieved complete and 13 partial remissions, for an overall response rate of 21% (95% confidence interval (CI), 12-33%); 27 additional patients (41%) had stable and 25 (38%) increasing disease. The median time to progression was 3.8 months. Median survival was 7.8 months, and the probability of surviving beyond 12 months was 21.2%. Out of 60 patients with tumour-related symptoms, who were considered evaluable for clinical benefit response, 26 (43%) experienced significant palliation. The median time to achieve a clinical benefit response was 7 weeks, and its median duration was 22 weeks. Chemotherapy was well-tolerated with leukopenia/granulocytopenia representing the most common and dose-limiting side-effect. Gastrointestinal and other subjective toxicities were infrequent and generally rated minor. We conclude that the combination of gemcitabine, epirubicin and G-CSF seems to be an effective palliative treatment with only moderate toxic effects in patients with metastatic pancreatic adenocarcinoma. Our results in terms of objective and clinical benefit response, as well as survival seem to suggest an advantage over gemcitabine-monotherapy, though this remains to be confirmed in a randomized trial.
