The purpose of our study was to compare progression-free survival and quality of life (QOL) after cisplatin-gemcitabine (CG) or epirubicin-gemcitabine (EG) in chemotherapy-naive patients with unresectable non-small-cell lung cancer. Patients (n=240) were randomised to receive gemcitabine 1125 mg x m(-2) (days 1 and 8) plus either cisplatin 80 mg x m(-2) (day 2) or epirubicin 100 mg x m(-2) (day 1) every 3 weeks for a maximum of five cycles. Eligible patients had normal organ functions and Eastern Cooperative Oncology Group performance status <or=2. QOL was measured with European Organisation for Research and Treatment of Cancer QLQ-C30 and LC13 questionnaires. There were no significant differences in median progression-free survival (CG 26 weeks, EG 23 weeks), median overall survival (CG 43 weeks, EG 36 weeks), or tumour response rates (CG 46%, EG 36%). Toxicity was mainly haematologic. In the EG arm granulocytopenia occurred more frequently, leading to more febrile neutropenia. Also, elevation of serum transaminases, mucositis, fever, and decline in LVEF were more common in the EG arm. In the CG arm, more patients experienced elevated serum creatinine levels, sensory neuropathy, nausea, and vomiting. Global QOL was not different in both arms. Progression-free survival, overall survival, response rate, and QOL were not different between both arms; however, overall toxicity was more severe in the EG arm.

The two taxanes (paclitaxel and docetaxel) are widely employed in standard antineoplastic practice. Although these agents are now well established, some toxic side effects have been reported. Toxicity of these agents includes bone marrow suppression (principally neutropenia), hypersensitivity reactions, cutaneous reactions, edema and neurotoxicity. The most prominent neurotoxicity is a sensory neuropathy. Controlling neuropathy is crucial for maintaining the quality of life of patients because it is usually persistent and hard to manage. The precise mechanism for taxane-induced neuropathy is still unknown. The taxanes are known to promote aggregation of intracellular microtubules. Abnormal aggregation of microtubules in the neuronal cells may cause this neuropathy. In addition, the taxanes have been suggested to have intrinsic toxicity and directly injure the cells. A better understanding of the mechanism for this neuropathy may improve the quality of life of patients who undergo taxane antineoplastic therapy.

High and intermediate grade non-Hodgkin's lymphomas (NHL) require treatments with aggressive chemotherapy schedules. However, low grade NHLs display a low chemoresponsiveness and patients aged >65 years often do not tolerate anthracycline and corticosteroid-containing chemotherapy regimens. Therapeutic options in this subset of patients are watchful waiting, oral alkylating agents, purine nucleoside analogues, combination chemotherapy, interferon and monoclonal antibodies. The approval of rituximab, an unconjugated chimeric antibody against the CD20 antigen for the treatment of B-cell NHL marked a milestone in the development of antibody treatment. Moreover, promising results have also been found with oxaliplatin in patients with NHL and reversible, cumulative, peripheral sensory neuropathy is the principle dose-limiting factor of oxaliplatin therapy. On the basis of these considerations we have performed a feasibility study in NHL in patients aged >65 years using as schedule: 130 mg/m2 oxaliplatin every 21 days and 375 mg/m2 rituximab weekly. We have enrolled 8 patients, 2 males and 6 females (mean age 69.2+/-3.1 years; median, 67 years) affected by intermediate or high grade stage III/IV NHL. Six patients have cardiac abnormalities (myocardial function between 45 and 50%) and 1 increase of transaminasemia due to active chronic hepatitis. All the patients included in the study were treated for at least 3 cycles and 31 cycles were completed. We have recorded grade I/II (CTC) neurotoxicity in 30%, grade I anemia in 25% and grade I neutropenia in 20% of the patients. No infusional reactions, liver or renal toxicity neither nausea and/or vomiting were recorded. One complete response, 3 partial response and 3 minimal response were obtained at 11 months of median time follow-up. These results demonstrate the feasibility of this schedule which offers a suitable alternative regimen to treat elderly patients with NHL and shows a good efficacy and an acceptable toxicity profile.

We evaluated the reliability of CTC v 2.0 based on source documents and also studied the degree of inconsistency in toxicity grading. Five clinical research coordinators from the National Cancer Center Hospital independently reviewed source documents from 17 patients and graded toxicities in the following common adverse events: diarrhea, nausea, stomatitis/pharyngitis, vomiting, febrile neutropenia, infection, infection unknown source, and sensory neuropathy. If grading was already documented on the medical chart, it was masked so that the coordinator could perform the evaluation without information bias. After the completion of toxicity grading, the participating coordinators discussed each case, and a consensus was reached for final toxicity grading. The proportion of agreement for each toxicity criteria are as follows: diarrhea; 0.59 (95%CI 0.35-0.82), nausea; 0.47 (0.23-0.71), stomatitis/pharyngitis; 0.59 (0.35-0.82), vomiting; 0.71 (0.49-0.92), febrile neutropenia; 0.88 (0.73-1.04), infection; 0.82 (0.64-1.01), infection by unknown source; 0.82 (0.64-1.01), sensory neuropathy; 0.65 0.42-0.87). The cause of variability largely depended on the differences in individual clinical assessment, and misunderstanding of toxicity criteria by coordinators has been observed. Even in a single institution environment, variability exists in the toxicity assessment and grading. Good training and education on toxicity assessment using common criteria and development of translated manual, including the interpretation of criteria assessment, may help reduce variability.

The purpose of this study was to evaluate the efficacy, assessed as response rate, and toxicity of UFT (Tegafur-Uracil) in combination with oxaliplatin as first-line treatment of advanced colorectal cancer (CRC). In all, 84 patients with recurrent or metastatic CRC with measurable disease were included. Treatment consisted of oxaliplatin 85 mg m(-2) in 120-min intravenous (i.v.) infusion on days 1 and 15; i.v. l,leucovorin (l,LV) 250 mg m(-2) given in 2 h on day 1, followed by oral UFT 390 mg m(-2) on days 1-14, and oral l,LV 7.5 mg/12 h on days 2-14. Cycles were repeated every 28 days. A total of 492 cycles of chemotherapy were delivered with a median of six per patient (range 1-12). There was one complete response (1%) and 28 partial responses (34%) for an overall response rate of 35% (95% confidence interval (CI): 24-46%). A total of 36 patients (44%) had stable disease, whereas 17 (21%) had a progression. The median time to progression was 7.3 months and the median overall survival was 16.8 months. A prescheduled preliminary analysis was performed after inclusion of 16 patients who detected a high gastrointestinal toxicity, which led to a reduction of the UFT dose to 300 mg m(-2). With this new dosage, grade 3-4 diarrhoea and grade 3-4 nausea/vomiting dropped to 21 and 14% of patients, respectively. Other grade 3-4 toxicities were stomatitis in one (1%), anaemia in three (5%), neutropenia in two (3%), thrombocytopenia in one(1%), fatigue in six (9%), peripheral sensory neuropathy in nine (14%) and laryngopharyngeal dysesthesia in two patients (2%). The combination of oxaliplatin and UFT-l,LV is an active, easy-to-administer regimen with moderate toxicity. Hence, this regimen is worthy of further investigation.

We prospectively investigated the efficacy and safety of combining weekly vinorelbine (VNB) with weekly 24-h infusion of high-dose 5-fluorouracil (5-FU) and leucovorin (LV) in the treatment of patients with advanced breast cancer (ABC). Vinorelbine 25 mg m(-2) 30-min intravenous infusion, and high-dose 5-FU 2600 mg m(-2) plus LV 300 mg m(-2) 24-h intravenous infusion (HDFL regimen) were given on days 1 and 8 every 3 weeks. Between June 1999 and April 2003, 40 patients with histologically confirmed recurrent or metastatic breast cancer were enrolled with a median age of 49 years (range: 36-68). A total of 25 patients had recurrent ABC, and 15 patients had primary metastatic diseases. The overall response rate for the intent-to-treat group was 70.0% (95% CI: 54-84%) with eight complete responses and 20 partial responses. All 40 patients were evaluated for survival and toxicities. Among a total of 316 cycles of VNB-HDFL given (average: 7.9: range: 4-14 cycles per patient), the main toxicity was Gr3/4 leucopenia and Gr3/4 neutropenia in 57 (18.0%) and 120 (38.0%) cycles, respectively. Gr1/2 infection and Gr1/2 stomatitis were noted in five (1.6%) and 59 (18.7%) cycles, respectively. None of the patients developed Gr3/4 stomatitis or Gr3/4 infection. Gr2/3 and Gr1 hand-foot syndrome was noted in two (5.0%) and 23 (57.5%) patients, respectively. Gr1 sensory neuropathy developed in three patients. The median time to progression was 8.0 months (range: 3-25.5 months), and the median overall survival was 25.0 months with a follow-up of 5.5 to 45+ months. This VNB-HDFL regimen is a highly active yet well-tolerated first-line treatment for ABC.

Capecitabine and docetaxel have single-agent activity in upper gastrointestinal tumours, and have together demonstrated preclinical synergy and a survival benefit in breast cancer, and high response rates in first-line metastatic gastric cancer. This trial assessed the efficacy, safety and feasibility of capecitabine in combination with docetaxel in patients with metastatic oesophageal cancer. In all, 24 patients with advanced disease (17 squamous cell carcinoma and seven adenocarcinoma) received oral capecitabine (1000 mg m(-2) twice daily on days 1-14) plus intravenous docetaxel (75 mg m(-2) on day 1) every 3 weeks as first- (n = 16) or second-line (n = 8) therapy. Patients received a median of four cycles of treatment (range, 0-6). The median follow-up is 16.5 months (range, 7.9-21.4 months). Intent-to-treat efficacy analysis showed an overall response rate of 46%. Of the 11 responders (one complete and 10 partial), nine of 16 (56%) received first-line and two of eight (25%) received second-line therapy. The median time to progression was 6.1 months (95% confidence interval (CI), 4.5-7.7 months). The median survival was 15.8 months (95% CI, 7.8-23.9 months). Severe adverse events (grade 3/4) reported were: neutropenia (42%, including febrile neutropenia 8%), hand-foot syndrome (29%), diarrhoea (13%), sensory neuropathy (13%), anaemia (8%) and fatigue (8%). Capecitabine plus docetaxel has a manageable adverse event profile and very promising activity in metastatic oesophageal cancer, at least comparable to other doublet regimens. Therefore, the combination merits further investigation in this setting.

Oxaliplatin plus fluorouracil/folinic acid (5-FU/FA) every 2 weeks has shown promising activity in advanced gastric cancer. This study assessed the efficacy and safety of weekly oxaliplatin plus 5-FU/FA (FUFOX regimen) in the metastatic setting. Patients with previously untreated metastatic gastric cancer received oxaliplatin (50 mg m(-2)) plus FA (500 mg m(-2), 2-h infusion) followed by 5-FU (2000 mg m(-2), 24-h infusion) given on days 1, 8, 15 and 22 of a 5-week cycle. The primary end point of this multicentre phase II study was the response rate according to RECIST criteria. A total of 48 patients were enrolled. Median age was 62 years and all patients had metastatic disease, with a median number of three involved organs. The most common treatment-related grade 3/4 adverse events were diarrhoea (17%), deep vein thrombosis (15%), neutropenia (8%), nausea (6%), febrile neutropenia (4%), fatigue (4%), anaemia (4%), tumour bleeding (4%), emesis (2%), cardiac ischaemia (2%) and pneumonia (2%). Grade 1/2 sensory neuropathy occurred in 67% of patients but there were no episodes of grade 3 neuropathy. Intent-to-treat analysis showed a response rate of 54% (95% CI, 39-69%), including two complete responses. At a median follow-up of 18.1 months (range 11.2-26.2 months), median survival is 11.4 months (95% CI, 8.0-14.9 months) and the median time to progression is 6.5 months (95% CI, 3.9-9.2 months). The weekly FUFOX regimen is well tolerated and shows notable activity as first-line treatment in metastatic gastric cancer.

Ixabepilone (Ix) (BMS-247550) is a potent member of a new class of microtubule-stabilizing cytotoxic agents known as epothilones. In pre-clinical studies, Ix has shown anticancer activity against several cancer types, including paclitaxel-resistant models, both in vitro and in vivo. The major toxicities associated with Ix are myelosuppression, sensory neuropathy and neutropenia. Other minor side-effects include asthenia/fatigue, stomatitis, anorexia, alopecia, skin reaction, hypersensitivity reactions and a fluid-retention syndrome. Although Ix is functionally correlated to taxanes, no previous evidence exists regarding Ix-related nail disorders. Here, we report a case of a 59-year-old woman treated with Ix at 40 mg/m2 day 1 q 21 days who, after 8 cycles of therapy, developed onycholysis and subungual hemorrhagic bullas in the fingernails.

A multicentre phase II trial to determine the efficacy of vinflunine as second-line therapy in patients with advanced transitional cell carcinoma (TCC) of the bladder; secondary objectives were to assess duration of response, progression-free survival (PFS) and overall survival (OS), and to evaluate the toxicity associated with this treatment. Patients had tumours that failed or progressed after first-line platinum-containing regimens for advanced or metastatic disease, or had progressive disease after platinum-containing chemotherapy given with adjuvant or neoadjuvant intent. Response and adverse events were assessed according to WHO criteria and NCI-CTC (version 2), respectively. Out of 51 patients treated with 320 mg m(-2) of vinflunine, nine patients responded to the therapy yielding an overall response rate of 18% (95% CI: 8.4-30.9%), and 67% (95%CI: 52.1-79.3%) achieved disease control (PR+SD). Of note, responses were seen in patients with relatively poor prognostic factors such as a short (<12 months) interval from prior platinum therapy (19%, including an 11% response rate in those progressing <3 months after platinum treatment), prior treatment for metastatic disease (24%), prior treatment with vinca alkaloids (14%) and visceral involvement (20%). The median duration of response was 9.1 months (95% CI: 4.2-15.0) and the median PFS was 3.0 months (95% CI: 2.4-3.8). The median OS was 6.6 months (95% CI: 4.8-7.6). The main haematological toxicity was grade 3-4 neutropenia, observed in 67% of patients (42% of cycles). Febrile neutropenia was observed in five patients (10%) and among them two were fatal. Constipation was frequently observed (but was manageable and noncumulative) and was grade 3-4 in only 8% of patients. The incidence of grade 3 nausea and vomiting was very low (4 and 6% of patients, respectively). Neither grade 3-4 sensory neuropathy nor severe venous irritation was observed. Moreover, and of importance in this particular study population, no grade 3-4 renal function impairment was observed. Vinflunine is an active agent for the treatment of platinum-pretreated bladder cancer, and these results warrant further investigation in phase III trials, either as monotherapy or in combination with other agents as treatment of advanced/metastatic TCC of the bladder.
