Perioperative dose-dense methotrexate, vinblastine, doxorubicin, and cisplatin in muscle-invasive bladder cancer (VESPER): survival endpoints at 5 years in an open-label, randomised, phase 3 study.

BACKGROUND: The optimal perioperative chemotherapy for patients with muscle-invasive bladder cancer is not defined. The VESPER (French Genito-Urinary Tumor Group and French Association of Urology V05) trial reported improved 3-year progression-free survival with dose-dense methotrexate, vinblastine, doxorubicin and cisplatin (dd-MVAC) versus gemcitabine and cisplatin (GC) in patients who received neoadjuvant therapy, but not in the overall perioperative setting. In this Article, we report on the secondary endpoints of overall survival and time to death due to bladder cancer at 5-year follow-up. METHODS: VESPER was an open-label, randomised, phase 3 trial done at 28 university hospitals or comprehensive cancer centres in France, in which adults (age ≤18 years and ≤80 years) with primary bladder cancer and histologically confirmed muscle-invasive urothelial carcinoma were randomly allocated (1:1; block size four) to treatment with dd-MVAC (every 2 weeks for a total of six cycles) or GC (every 3 weeks for a total of four cycles). Overall survival and time to death due to bladder cancer (presented as 5-year cumulative incidence of death due to bladder cancer) was analysed by intention to treat (ITT) in all randomly assigned patients. Overall survival was assessed by the Kaplan-Meier method with the treatment groups compared with log-rank test stratified for mode of administration of chemotherapy (neoadjuvant or adjuvant) and lymph node involvement. Time to death due to bladder cancer was analysed with an Aalen model for competing risks and a Fine and Gray regression model stratified for the same two covariates. Results were presented for the total perioperative population and for the neoadjuvant and adjuvant subgroups. The trial is registered with ClinicalTrials.gov, NCT01812369, and is complete. FINDINGS: From Feb 25, 2013, to March 1, 2018, 500 patients were randomly assigned, of whom 493 were included in the final ITT population (245 [50%] in the GC group and 248 [50%] in the dd-MVAC group; 408 [83%] male and 85 [17%] female). 437 (89%) patients received neoadjuvant chemotherapy. Median follow-up was 5·3 years (IQR 5·1-5·4); 190 deaths at the 5-year cutoff were reported. In the perioperative setting (total ITT population), we found no evidence of association of overall survival at 5 years with dd-MVAC treatment versus GC treatment (64% [95% CI 58-70] vs 56% [50-63], stratified hazard ratio [HRstrat] 0·79 [95% CI 0·59-1·05]). Time to death due to bladder cancer was increased in the dd-MVAC group compared with in the GC group (5-year cumulative incidence of death: 27% [95% CI 21-32] vs 40% [34-46], HRstrat 0·61 [95% CI 0·45-0·84]). In the neoadjuvant subgroup, overall survival at 5 years was improved in the dd-MVAC group versus the GC group (66% [95% CI 60-73] vs 57% [50-64], HR 0·71 [95% CI 0·52-0·97]), as was time to death due to bladder cancer (5-year cumulative incidence: 24% [18-30] vs 38% [32-45], HR 0·55 [0·39-0·78]). In the adjuvant subgroup, the results were not conclusive due to the small sample size. Bladder cancer progression was the cause of death for 157 (83%) of the 190 deaths; other causes of death included cardiovascular events (eight [4%] deaths), deaths related to chemotherapy toxicity (four [2%]), and secondary cancers (four [2%]). INTERPRETATION: Our results on overall survival at 5 years were in accordance with the primary endpoint analysis (3-year progression-free survival). We found no evidence of improved overall survival with dd-MVAC over GC in the perioperative setting, but the data support the use of six cycles of dd-MVAC over four cycles of GC in the neoadjuvant setting. These results should impact practice and future trials of immunotherapy in bladder cancer. FUNDING: French National Cancer Institute.

Final Results of the Randomized Phase II NorCap-CA223 Trial Comparing First-Line All-Oral Versus Taxane-Based Chemotherapy for HER2-Negative Metastatic Breast Cancer.

BACKGROUND: The purpose of this study was to evaluate the efficacy of 3 first-line chemotherapy combination regimens for HER2-negative metastatic breast cancer (mBC). PATIENTS AND METHODS: In this open-label, 3-arm, randomized phase II trial, patients were randomized to all-oral NORCAP (vinorelbine/capecitabine), GEMPAC (gemcitabine/paclitaxel), or GEMDOC (gemcitabine/docetaxel) as first-line chemotherapy for HER2-negative mBC. Stratification factors were center, previous (neo)adjuvant anthracycline, and age. The primary end point was disease control rate (DCR; complete or partial response, or stable disease for ≥3 months). RESULTS: The DCR was 73% (95% confidence interval [CI], 59-85) with NORCAP (36 of 49 patients), 78% (95% CI, 64-88) with GEMPAC (39 of 50 patients), and 80% (95% CI, 66-90) with GEMDOC (40 of 50 patients). Objective response rates were 33% (16 of 49 patients), 24% (12 of 50 patients), and 50% (25 of 50 patients), respectively; median progression-free survival was 7.6, 9.0, and 11.4 months, respectively. Median overall survival was 30 to 31 months with all regimens. The most common Grade ≥3 adverse event with each regimen was neutropenia (24 patients [50%], 23 patients [46%], and 43 patients [86%], respectively). The most common nonhematological Grade ≥3 adverse event was fatigue. Grade 2 alopecia occurred in 36 patients (72%) who received GEMPAC and 38 patients (76%) who received GEMDOC, but only 4 patients (8%) who received NORCAP. There was no evidence of a detrimental effect of NORCAP on quality of life. CONCLUSION: All-oral NORCAP is an active first-line chemotherapy regimen and might be offered as an alternative to first-line taxane-based therapy for HER2-negative mBC, particularly if patients wish to avoid alopecia or frequent intravenous administrations.

Melatonin reduces oxidative stress and restores mitochondrial function in the liver of rats exposed to chemotherapeutics.

This study was undertaken to investigate whether administration of melatonin protects PVB-Induced oxidative and metabolic toxicity in the liver of Wistar rats. Adult male Wistar rats were intraperitoneally injected with either melatonin or PVB (cisplatin, vinblastine, and bleomycin) alone or combination for a period of 9 weeks. A significant increase in lipid peroxidation levels and decrease in catalase and superoxide dismutase activity levels were observed in the liver mitochondria of rats treated with PVB indicating increased oxidative stress. PVB treatment significantly decreased the succinate dehydrogenase activity with a significant increase in lactate dehydrogenase, glucose-6-phosphate dehydrogenase, aspartate aminotransaminase, alanine aminotransaminase, and glutamate dehydrogenase activities indicating deranged hepatic metabolism. Melatonin administration, on the other hand was found to significantly improve PVB-Induced biochemical changes, bringing them closer to the controls. The results from the study provide evidence that treatment with PVB affects hepatic metabolism in rats by inducing oxidative stress followed by decreasing mitochondrial oxidation and also point towards the clinical potential of melatonin as an adjuvant therapy to conventional chemotherapeutic regimens.

A three-arm randomized phase II study of oral vinorelbine plus capecitabine versus oral vinorelbine and capecitabine in sequence versus docetaxel plus capecitabine in patients with metastatic breast cancer previously treated with anthracyclines.

Owing to the increased number of patients treated with anthracycline-based adjuvant chemotherapy, there is a need for new effective and tolerable nonanthracycline regimens in metastatic breast cancer. Patients with HER2-negative metastatic breast cancer previously treated with anthracyclines in (neo)adjuvant setting were randomized to fully oral 3 weekly cycles of the combination of oral vinorelbine with capecitabine (V + C), to the same drugs alternating every three cycles (V↔C), or to the combination of docetaxel and capecitabine (D + C). V was given at 80 mg/m(2) (after the first cycle at 60 mg/m(2)) on days 1 and 8 in the V + C arm and weekly in the V↔C arm, C at 1,000 mg/m(2) bid from days 1 to 14, and D on day 1 at 75 mg/m(2). The primary end point was disease control rate (CR + PR + NC ≥ 3 months). A total of 139 patients were randomly assigned to V + C (44 patients), V↔C (47 patients), and D + C (48 patients). After an independent review, the disease control rate in the intent-to-treat population in the V + C, V↔C, and D + C arms [95% CI] was 70.5% [54.8-83.2], 37.0% [23.2-52.5], and 70.8% [55.9-83.1], and the median overall survival 22.2, 19.4, and 24.2 months, respectively. When taken into account the disease control rate, the alternating V↔C regimen seems to be less effective compared with V + C or D + C combinations. Combinations of V + C or D + C showed similar efficacy and a different toxicity profile; V + C induced less neutropenia, infection, hand-foot syndrome, fatigue/asthenia, and alopecia, whereas D + C - less gastrointestinal toxicity. V + C combination constitutes a valuable fully oral alternative option to D + C in patients with metastatic breast cancer previously treated with anthracyclines in (neo)adjuvant setting, while offering the advantages of an all-oral treatment.

All-oral combination of vinorelbine and capecitabine as first-line treatment in HER2/Neu-negative metastatic breast cancer.

PURPOSE: To evaluate the efficacy and safety of an all-oral vinorelbine and capecitabine combination therapy in anthracycline- ± taxane-pretreated HER2/Neu-negative metastatic breast cancer (MBC). METHODS: A phase 2 trial including women >18 years with HER2/Neu-negative MBC previously exposed to anthracycline- ± taxane-based chemotherapy in the adjuvant or neoadjuvant setting. Enrolled patients received oral vinorelbine 60 mg/m(2) on days 1 and 8 and oral capecitabine 1,000 mg/m(2) twice daily on days 1-14 on a 3 weekly schedule. Patients with progressive disease after 3 cycles discontinued the study, while the remaining patients continued treatment for a maximum of 6 cycles. RESULTS: From January 2007 to March 2011, 30 patients were enrolled in this study (median age 47 years). In the 28 evaluable patients, the overall response rate was 57.1 % (95 % CI 30-67 %), including 3 complete (10.7 %) and 13 partial (46.4 %) responses. Six (21.4 %) patients suffered from disease progression. With a median follow-up time of 13 months, the median time to disease progression was 8.6 months (95 % CI 6.2-10.6 months) and the median survival time was 27.2 months. Treatment-related adverse events were manageable, and no World Health Organization grade 4 toxicities were noted. Neutropenia observed in 6 (21.4 %) patients was the main grade 3 toxicity. Grade 3 nausea and vomiting were reported in 2 (7.1 %) and 3 (10.7 %) patients, respectively. Two (7.1 %) patients developed grade 3 hand and foot syndrome. CONCLUSION: These results show that the combination of oral vinorelbine and capecitabine is an effective and well-tolerated first-line regimen for HER2/Neu-negative MBC patients pretreated with anthracyclines ± taxanes.

A neoadjuvant biochemotherapy approach to stage III melanoma: analysis of surgical outcomes.

AIMS: Completion lymph node dissection (CLND) and adjuvant therapy are recommended for node-positive melanoma patients. We sought to analyze our institution's experience with neoadjuvant biochemotherapy in stage III patients. METHODS: Clinical information was extracted from a retrospective database on stage III melanoma patients. Eligible patients received two cycles of biochemotherapy prior to their CLND. RESULTS: There were 153 patients available for analysis. The average tumor depth was 2.5 mm. More than half of all patients presented with sentinel lymph node-positive disease. Surgical complications occurred in 23% of patients. Patients who experienced an adverse event during their neoadjuvant therapy had a worse overall survival when compared with those who did not (p = 0.005). CONCLUSION: Our data suggest that aggressive neoadjuvant treatment prior to CLND does not impact surgical complications. Our surgical outcomes are similar to the current literature when adjuvant therapy is used in stage III melanoma. The inability to tolerate neoadjuvant therapy in stage III melanoma is a negative prognostic indicator.

A multicenter randomized phase III trial of vinorelbine/gemcitabine doublet versus capecitabine monotherapy in anthracycline- and taxane-pretreated women with metastatic breast cancer.

BACKGROUND: The Breast Cancer Study Group of the Hellenic Oncology Research Group conducted a phase III trial of single-agent capecitabine versus the vinorelbine/gemcitabine doublet in patients with metastatic breast cancer (MBC) pretreated with anthracyclines and taxanes. The primary objective was to demonstrate superiority of combination treatment in terms of progression-free survival (PFS). PATIENTS AND METHODS: Women with MBC were randomly assigned to receive either capecitabine (Cap arm: 1250 mg/m(2) twice daily, on days 1-14) or vinorelbine/gemcitabine doublet (VG arm: vinorelbine 25 mg/m(2); gemcitabine 1000 mg/m(2); both drugs on days 1 and 15). RESULTS: Seventy-four women were treated on each arm and median PFS was 5.4 versus 5.2 months (P = 0.736), for VG and Cap, respectively. Median overall survival was 20.4 months for the VG arm and 22.4 months for the Cap arm (P = 0.319). Overall response rate was 28.4% in the VG arm and 24.3% in the Cap arm (P = 0.576). Both regimens were generally well tolerated. Neutropenia and fatigue were more common with VG arm and hand-foot syndrome with Cap arm. CONCLUSIONS: This trial failed to demonstrate superiority of vinorelbine/gemcitabine doublet over single-agent capecitabine in terms of PFS. Given the favorable toxicity and convenience of oral administration, single-agent capecitabine is recommended for compliant patients.

Astragalus polysaccharide injection integrated with vinorelbine and cisplatin for patients with advanced non-small cell lung cancer: effects on quality of life and survival.

A platinum-based two-drug regimen is currently the standard of care for patients with advanced non-small-cell lung cancer (NSCLC). However, chemotherapy-induced side effects still remain a significant clinical problem. Astragalus polysaccharide (APS) is a polysaccharide isolated from the radix of astragalus membranaceus, a commonly used herbal compound in traditional Chinese medicine. APS was reported to increase tumor response, stabilize and improve performance status, and reduce chemotherapy toxicity. We designed this trial to determine whether APS injection integrated with vinorelbine and cisplatin (VC) offered an improved QOL over VC for patients with advanced NSCLC. Secondary objectives were tumor response, toxicity, and survival results. One hundred thirty-six patients with histologically or cytologically confirmed NSCLC were enrolled in this study from May 2008 to March 2010. Patients were randomized to receive either VC (VC arm) or VC combined with APS (VC-APS arm). The objective response rate of was 42.64% in the VC-APS arm and 36.76% in the VC arm. The difference was not statistically significant (P = 0.483). Median survival time was 10.7 and 10.2 months (P = 0.76) in VC-APS arm and VC arm, with 1-year survival rates of 35.3 and 32.4% (P = 0.717), respectively. After 3 cycles of treatment, there were significant differences in the overall patient QOL (P = 0.003), physical function (P = 0.01), fatigue (P < 0.001), nausea and vomiting (P < 0.001), pain (P = 0.007), and loss of appetite (P = 0.023) between the two study groups. In summary, we have proved that the treatment of APS integrated with VC had significantly improved QOL in patients with advanced NSCLC compared with VC alone.

A phase I study of vinflunine in combination with capecitabine in patients with metastatic breast cancer previously treated with anthracyclines and taxanes.

PURPOSE: A phase I study was performed to determine the maximal tolerated dose (MTD), recommended dose (RD), safety and efficacy of vinflunine when combined with capecitabine in patients with metastatic breast cancer (MBC) previously treated with anthracyclines and taxanes, with pharmacokinetic blood sampling to test potential drug-drug interactions. PATIENTS AND METHODS: Sixteen patients with MBC who had received anthracyclines and taxanes in the neo/adjuvant setting, if progression occurred during or within 12 months of chemotherapy completion, and/or as first-line chemotherapy of MBC were enrolled. Vinflunine (VFL) was given on day 1 with capecitabine (CAPE) twice daily from days 1 to 14, every 3 weeks. Three dose levels (DL) were investigated (DL1: VFL 280 mg/m² and CAPE 1,650 mg/m²/day, DL2: VFL 320 mg/m² and CAPE 1,650 mg/m²/day and DL3: VFL 280 mg/m² and CAPE 2,000 mg/m²/day). RESULTS: The RD was established as vinflunine 280 mg/m² on day 1 plus capecitabine 1,650 mg/m²/day on days 1 to 14 given every 3 weeks. Dose-limiting toxicities were grade 4 neutropenia lasting at least 7 days for 2 patients, anorexia with fatigue for 1 patient and diarrhoea with fatigue, anorexia and febrile neutropenia for 1 patient. Neutropenia was the main toxicity of the combination, it was reported in 15 patients (93.8%) with grade 3 in 7 patients (43.8%) and 22.6% of cycles and grade 4 in 7 patients (43.8%) and 19.8% of cycles. Complications were rare with only one patient experiencing febrile neutropenia at DL exceeding the RD. The most frequent non-haematological toxicities were fatigue and gastrointestinal disorders; however, no grade 3 or 4 episode was observed at the RD. Hand-foot syndrome was reported in 5 patients (31.3%) and 22.6% of cycles, no episode of grade 3 was seen. Concerning pharmacokinetics, no modifications were detected for VFL, while slight accumulation between days 1 and 14 was observed for 5-FU formed from CAPE. The risk of clinical significant drug-drug interaction was considered weak. Objective partial responses were reported in 7 patients, yielding a response rate of 43.8% in the all-treated population according to the investigator assessment. CONCLUSIONS: The combination of vinflunine and capecitabine is safe and showed promising antitumour activity in MBC patients who have failed prior anthracyclines and taxanes. Further clinical development of this combination is warranted.

Vinflunine: drug safety evaluation of this novel synthetic vinca alkaloid.

INTRODUCTION: Vinca alkaloid agents have been widely used in several different types of malignancies. However, cancer cells, ultimately, develop resistance to these agents. Therefore, the development of new agents with improved efficacy is warranted. Recently, a new synthetic vinca alkaloid, vinflunine, was developed through the addition of two fluor molecules by superacidic chemistry. AREAS COVERED: The authors describe the development of the new vinca alkaloid vinflunine from preclinical studies to the late-stage clinical trials, highlighting the most important clinical and safety data of vinflunine. In vitro and in vivo studies have shown a superior efficacy of vinflunine over other vinca alkaloids and with an improved safety profile. Early clinical trials have demonstrated a significant activity of vinflunine against different malignancies. Phase III trials showed that vinflunine increases survival in patients with advanced transitional cell carcinoma of the urothelium (TCCU) tract treated in the second-line and is as effective as docetaxel in second-line NSCLC. EXPERT OPINION: Vinflunine is currently approved in Europe for the treatment of second-line TCCU and is currently being developed in other malignancies. It has been shown to have predictable and manageable adverse effects, such as neutropenia, anemia, constipation and fatigue.

Incidence of chemotherapy-induced amenorrhea associated with epirubicin, docetaxel and navelbine in younger breast cancer patients.

BACKGROUND: The rates of chemotherapy-induced amenorrhea (CIA) associated with docetaxel-based regimens reported by previous studies are discordant. For navelbine-based chemotherapies, rates of CIA have seldom been reported. METHODS: Of 170 premenopausal patients recruited between January 2003 and September 2008, 78 were treated with fluorouracil plus epirubicin and cyclophosphamide (FEC), 66 were treated with docetaxel plus epirubicin (TE), and 26 were treated with navelbine plus epirubicin (NE). Patient follow-up was carried up every 3-4 months during the first year, then every 9-12 months during subsequent years. RESULTS: In univariate analysis, the rates of CIA were 44.87% for the FEC regimen, 30.30% for the TE regimen and 23.08% for the NE regimen (P = 0.068). Significant differences in the rates of CIA were not found between the FEC and TE treatment groups (P > 0.05), but were found between the FEC and NE treatment groups (P < 0.05). Furthermore, no significant differences were found between the TE and NE regimens (P > 0.05). Tamoxifen use was a significant predictor for CIA (P = 0.001), and age was also a significant predictor (P < 0.001). In multivariate analysis, age (P < 0.001), the type of chemotherapy regimens (P = 0.009) and tamoxifen use (P = 0.003) were all significant predictors. CONCLUSIONS: Age and administration of tamoxifen were found to be significant predictive factors of CIA, whereas docetaxel and navelbine based regimens were not associated with higher rates of CIA than epirubicin-based regimen.

A randomized controlled pilot trial of "Feiji Recipe" on quality of life of non-small cell lung cancer patients.

In order to pilot a study observing the feasibility of applying the Core Quality of Life Questionnaire (QLQ-C30) version 2.0 to assess the quality of life (QOL) of patients with NSCLC treated with Feiji Recipe, a randomized, parallel controlled clinical trial was conducted in the university-affiliated hospital. Seventy inpatients who met the inclusion criteria were randomized into the study, and 60 cases were available as subjects for QOL data analysis. The subjects were randomly assigned to one of three groups: the Feiji Recipe group (A); the Feiji Recipe combined with chemotherapy group (B); and the chemotherapy group (C) in which the patients were treated with vinorelbine plus cisplatin (NP) or gemcitabine plus cisplatin (GP). QOL was assessed with the Chinese version of the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire C30. Sixty cases that finished the questionnaires were analyzed, and we found that patients who received chemotherapy had low QOL, in terms of their global health, role, emotional, social, economic status and symptom burden including fatigue, nausea and vomiting, dyspnea, loss of appetite and abnormal bowel movements. Simultaneous treatment with Feiji Recipe and chemotherapy was able to prevent the worsening of function in terms of role, social, fatigue and global health. The Core Quality of Life Questionnaire (QLQ-C30) version 2.0 can be used to evaluate the QOL of patients with NSCLC treated by Chinese herbal medicine. Feiji Recipe might partially improve the QOL of NSCLC patients when administered alone or in combination with chemotherapy. No unexpected side effects were observed. However, further double-blinded placebo controlled studies are strongly recommended.

A Phase II trial of the combination of vinorelbine and capecitabine as second-line treatment in metastatic breast cancer previously treated with taxanes and/or anthracyclines.

PURPOSE: Survival time for metastatic breast cancer (MBC) can be substantially improved by combination chemotherapy in the adjuvant setting. Capecitabine and vinorelbine have shown considerable efficacy and favourable toxicity as single agents. The aim of this study is to evaluate the response to the combination of capecitabine and vinorelbine as second-line treatment in patients previously treated with taxanes and/or anthracyclines. PATIENTS AND METHODS: Thirty-nine patients with MBC, who received a combination of vinorelbine and capecitabine were included in the study. RESULTS: Overall response rate was 53.9% and disease progression rate was 28.2% for patients who received six cycles of therapy, rates significantly higher than the three-cycle group. The treatment was generally well tolerated and toxicity was mild. CONCLUSIONS: The combination of capecitabine and vinorelbine as salvage therapy in anthracycline- and/or taxane-pre-treated patients with MBC seems to be effective and safe, even more so as the number of treatment cycles increases.

All-oral combination of oral vinorelbine and capecitabine as first-line chemotherapy in HER2-negative metastatic breast cancer: an International Phase II Trial.

BACKGROUND: This multicentre, international phase II trial evaluated the efficacy and safety profile of a first-line combination of oral vinorelbine plus capecitabine for women with metastatic breast cancer (MBC). METHODS: Patients with measurable, HER2-negative disease received, as a first line in metastatic setting, 3-weekly cycles of oral vinorelbine 80 mg m(-2) (after a first cycle at 60) on day 1 and day 8, plus capecitabine 1000 mg m(-2) (750 if >or=65 years of age) twice daily, on days 1-14. Treatment was continued until progression or unacceptable toxicity. RESULTS: A total of 55 patients were enrolled and 54 were treated (median age: 58.5 years). Most (78%) had visceral involvement and 63% had received earlier (neo)adjuvant chemotherapy. The objective response rate (RECIST) in 49 evaluable patients was 51% (95% confidence interval (CI), 36-66), including complete response in 4%. The clinical benefit rate (response or stable disease for >or=6 months) was 63% (95% CI, 48-77). The median duration of response was 7.2 months (95% CI, 6.4-10.2). After a median follow-up of 41 months, median progression-free survival was 8.4 months (95% CI, 5.8-9.7) and median overall survival was 29.2 months (95% CI, 18.2-40.1). Treatment-related adverse events were manageable, the main grade 3-4 toxicity was neutropaenia (49%); two patients experienced febrile neutropaenia and three patients had a neutropaenic infection (including one septic death). A particularly low rate of alopaecia was observed. CONCLUSION: These results show that the all-oral combination of oral vinorelbine and capecitabine is an effective and well-tolerated first-line regimen for MBC.

Vinflunine in platinum-pretreated patients with locally advanced or metastatic urothelial carcinoma: results of a large phase 2 study.

BACKGROUND: The activity and safety of vinflunine was evaluated in patients with locally advanced or metastatic urothelial carcinoma (UC) who developed disease progression within 12 months of platinum-containing chemotherapy. METHODS: Patients with UC were eligible if they received a prior platinum-based regimen in the neoadjuvant/adjuvant setting or as first-line treatment for advanced/metastatic disease and had developed disease progression within 12 months. Vinflunine was administered intravenously every 3 weeks. Patients with Karnofsky performance status of 80 or 90, impaired renal function, prior pelvic irradiation, or age>or=75 years received an initial dose of 280 mg/m2, which was escalated to 320 mg/m2 in Cycle 2 if well tolerated. All other patients received an initial dose of 320 mg/m2. The primary endpoint was response rate defined by an independent response review committee (IRRC). RESULTS: Per the IRRC, 22 patients achieved a partial response, with a response rate of 15% (95% confidence interval, 9%-21%) with a median duration of response of 6.0 months. Sixty-four (42%) patients had stable disease. The median progression-free survival was 2.8 months, and the median overall survival was 8.2 months. Myelosuppression was the most frequent adverse event, with grade 3 of 4 (adverse events were evaluated according to the National Cancer Institute Common Toxicity Criteria [version 2.0] guidelines) neutropenia reported in 58% of the patients. Grade 3 of 4 febrile neutropenia occurred in 10 (7%) patients. Nonhematologic treatment-related events (grade 3 of 4) were generally manageable and included constipation (17%), asthenia/fatigue (13%), ileus (5%), and abdominal pain (5%). No cumulative toxicity was observed. CONCLUSIONS: Vinflunine demonstrates moderate activity in patients with platinum-pretreated UC. Toxicity is manageable and noncumulative.

Preliminary results of M-VAC chemotherapy combined with mild hyperthermia, a new therapeutic strategy for advanced or metastatic transitional cell carcinoma of the urothelium.

OBJECTIVE: We evaluated the efficacy and safety of M-VAC chemotherapy combined with mild hyperthermia, a new therapeutic strategy for advanced metastatic transitional cell carcinoma of the urothelium. SUBJECTS AND METHODS: The subjects were 12 patients diagnosed with advanced metastatic transitional cell carcinoma of the urothelium. For mild hyperthermia, the patients' oral temperature was elevated to about 38 degrees C by heating for 20 min and retaining the heat for 20 min with a far-infrared heater. The antitumor effect was evaluated according to the RECIST, while adverse drug reactions were assessed based on the NCI-CTC. RESULTS: The antitumor effect was rated as partial remission (PR) in 10 of the 12 patients and stable disease in 2 patients, with an efficacy rate of 83% (10/12). All 10 patients who had achieved PR received three courses of treatment. Of the 12 patients, 5 died during the observation period, with survival for 9-23 months (mean: 15.6 months). Adverse drug reactions included myelosuppression in all patients (Grade 3 in 4 patients, Grade 4 in 8), and gastrointestinal toxicity, such as nausea or vomiting, which was mild (Grade 0 in 2 patients, Grade 1 in 8, Grade 2 in 1, Grade 3 in 1). CONCLUSIONS: The results of the present study suggest that M-VAC chemotherapy combined with mild hyperthermia, which potentiates the anticancer effect and reduces adverse drug reactions such as gastrointestinal symptoms, is a useful and safe method for the treatment of advanced transitional cell carcinoma of the urothelium.

LED phototherapy to prevent mucositis: a case report.

OBJECTIVE: The purpose of this case report was to evaluate the efficacy of phototherapy using light-emitting diodes (LEDs) to prevent oral mucositis in a Hodgkin's disease patient treated with the ABVD (doxorubicin [Adriamycin], bleomycin, vinblastine, and dacarbazine) chemotherapy regimen. BACKGROUND DATA: Mucositis is a common dose-limiting complication of cancer treatment, and if severe it can lead to alterations in treatment planning or suspension of cancer therapy, with serious consequences for tumor response and survival. Therefore, low-power lasers and more recently LEDs, have been used for oral mucositis prevention and management, with good results. MATERIALS AND METHODS: In this study, a 34-year-old man received intraoral irradiation with an infrared LED array (880 nm, 3.6 J/cm2, 74 mW) for five consecutive days, starting on chemotherapy day 1. In each chemotherapy cycle, he received the ABVD protocol on days 1 and 15, and received LED treatment for 5 d during each cycle. To analyze the results, the World Health Organization (WHO) scale was used to grade his mucositis, and a visual analogue scale (VAS) was used for pain evaluation, on days 1, 3, 7, 10, and 13 post-chemotherapy. RESULTS: The results showed that the patient did not develop oral mucositis during the five chemotherapy cycles, and he had no pain symptoms. CONCLUSION: LED therapy was a safe and effective method for preventing oral mucositis in this case report. However, further randomized studies with more patients are needed to prove the efficacy of this method.

Clinical feasibility of (neo)adjuvant taxane-based chemotherapy in older patients: analysis of >4,500 patients from four German randomized breast cancer trials.

INTRODUCTION: Despite the fact that people older than 65 years of age have the highest incidence of developing breast cancer, these patients are excluded from clinical trials in most cases. Furthermore, most physicians tend towards therapy regimens without the use of dose-dense, highly active taxane-based treatments because of a lack of data regarding toxicities of these compounds in older patients. METHODS: Pooled side-effect data were analyzed from four prospective, randomized clinical trials in which patients of different age groups (< 60 years, between 60 and 64 years, and > 64 years) with primary breast cancer received taxane-based chemotherapy. RESULTS: Dose delays, dose reductions, hospitalization, and therapy discontinuation increased with age. Hematologic toxicities and some nonhematologic toxicities were generally more common in older patients. Leucopenia increased from 55.3% in patients aged < 60 years to 65.5% in patients aged > 64 years (P < 0.001), and neutropenia increased from 46.9% to 57.4% (P < 0.001). There was no difference, however, in clinically more relevant febrile neutropenia between the different age groups. Thrombopenia shows a similar age-dependent increase, whereas there is no difference between the age groups concerning anemia. Hot flushes and elevated liver enzymes decreased with increasing age. CONCLUSIONS: The present pooled analysis of a substantial cohort of older primary breast cancer patients demonstrates that taxane-containing (neo)adjuvant chemotherapy is feasible in older patients and that toxicity can be reduced by sequential therapy regimens.

Vinflunine: a new microtubule inhibitor agent.

Vinflunine (Javlor) is the first fluorinated microtubule inhibitor belonging to the Vinca alkaloids family. Vinflunine is obtained by semisynthesis using superacidic chemistry to selectively introduce two fluorine atoms at the 20' position of the catharanthine moiety. This compound has been selected for clinical development on the basis of encouraging preclinical activity that warrants study in patients with a wide spectrum of solid tumors. Clinically significant activity has been seen in phase II studies, mainly in the treatment of transitional cell carcinoma of the urothelial tract, non-small cell lung cancer, and carcinoma of the breast. Vinflunine is currently in phase III trial assessment in patients with (second line) transitional cell carcinoma of the urothelium and first-line advanced breast cancer. The efficacy of vinflunine in patients with advanced non-small cell lung cancer previously treated with a platinum-containing regimen was confirmed by a large phase III trial.

Pemetrexed pharmacokinetics and pharmacodynamics in a phase I/II study of doublet chemotherapy with vinorelbine: implications for further optimisation of pemetrexed schedules.

The purpose of this study was to investigate the utility of plasma pharmacokinetic and pharmacodynamic measures including plasma deoxynucleosides, homocysteine and methylmalonic acid concentrations in understanding the time course and extent of the inhibition of thymidylate synthase (TS) by pemetrexed in the context of a phase I/II combination study with vinorelbine. Eighteen patients received supplementation with folic acid and Vitamin B(12) 1 week before beginning treatment with pemetrexed and vinorelbine administered in a dose-escalating manner on a 21-day cycle. Heparinised blood samples were collected from consenting patients in the first cycle for pharmacokinetic analyses and in the first two cycles for determination of plasma thymidine, deoxyuridine, homocysteine and methylmalonic acid concentrations. These values were correlated with response and toxicity. Plasma deoxyuridine was used as a measure of TS inhibition, and concentrations of deoxyuridine were significantly elevated relative to baseline on days 1 (P<0.01), 2 (P<0.001) and 3 (P<0.05) after treatment at all pemetrexed dose levels (400-700 mg m(-2)). The magnitude of deoxyuridine elevation correlated with pemetrexed area under the plasma concentration-time curve (AUC) (r(2)=0.23, P<0.05). However, deoxyuridine concentrations returned to baseline between 8 and 15 days after treatment with pemetrexed, suggesting that inhibition of TS was not durable. Pemetrexed AUC correlated with the percentage decline (relative to baseline) in both platelets (r(2)=0.58, P<0.001) and leucocytes (r(2)=0.26, P<0.05) at day 8. Baseline homocysteine was also significantly correlated with these measures of haematological toxicity (r(2)=0.37, P<0.01 and r(2)=0.39, P<0.01, respectively). In addition, there was a significant reduction of plasma homocysteine on days 8 (P<0.005) and 15 (P<0.05) in cycle 1 compared to baseline values. The results suggest that the TS inhibitory effects of pemetrexed are short-lived and make the case for a more frequent schedule of administration such as every 2 weeks. The lack of protracted TS inhibition may be due to concomitant vitamin administration, and this may be the mechanism by which vitamins prevent life-threatening toxicity from pemetrexed. Baseline homocysteine concentration remains a predictive marker for haematological toxicity even following folate supplementation.
