MVAC is more effective than DC in advanced urothelial cancer. G-CSF-supported MVAC is well tolerated and could be used instead of classic MVAC as first-line treatment in advanced urothelial carcinoma.

BACKGROUND.The toxicity of platinum-based combinations represents a common problem for patients with advanced urothelial carcinoma. The authors previously reported encouraging efficacy for the combination of carboplatin and gemcitabine in patients considered to be unfit for cisplatin-based treatment. The objective of the current multicenter Phase II study was to evaluate the safety and efficacy of the combination of gemcitabine and carboplatin as first-line treatment in unselected patients with advanced urothelial carcinoma. METHODS.Patients with previously untreated, bidimensionally measurable, inoperable or metastatic urothelial carcinoma were treated with carboplatin, area under the concentration curve of 5 (Day 1) and gemcitabine at a dose of 1000 mg/m 2 (Days 1 and 8), every 21 days for a total of 6 cycles. RESULTS.Sixty patients (49 men and 11 women, with a median age of 69 yrs) were enrolled in the current study. Intent-to-treat analysis demonstrated an objective response rate (ORR) of 38.4% (95% confidence interval [95% CI], 26 -51.8%) (11.7% complete responses and 26.7% partial responses). The median time to disease progression was 7.6 months (95% CI, 4.5-10.7 mos) and the median overall survival was 16.3 months (95% CI, 12-20.6 mos). The median survival was comparable to that reported for the combination of methotrexate, vinblastine, doxorubicin, and cisplatin (M-VAC) according to the Memorial Sloan-Kettering Cancer Center prognostic model for patients with similar baseline prognostic features. Grade 3 or 4 toxicity (according to the National Cancer Institute Common Toxicity Criteria [version 2.0]) included anemia (18%), thrombocytopenia (23%), and neutropenia (52%), with 7 episodes of febrile neutropenia (11%) reported. Nonhematologic toxicity was rare. One toxic death occurred during the study. CONCLUSIONS.The combination of gemcitabine and carboplatin appears to have considerable activity as the first-line treatment of unselected patients with advanced urothelial carcinoma with manageable toxicity, and deserves further evaluation in this setting.

The aim of the study was to evaluate the association of vascular endothelial growth factor (VEGF) genotypes with treatment efficacy in a randomized trial. This study compared two chemotherapy regimens (FOLFIRI versus XELIRI) combined with bevacizumab, as first-line treatment for metastatic colorectal cancer. DNA was extracted from blood samples of 173 patients participating in the trial. Genotyping was performed for selected SNPs (VEGF-1154, +936, -634, -2578 and -1498). All candidate genotypes were evaluated for associations with overall survival (OS), progression-free survival (PFS) and response rate (RR). There were no significant differences with respect to the distribution of genotypes in the treatment groups. The VEGF-1154 GG genotype was more frequent in patients not responding to treatment compared with responders (65.5 versus 39.8%, P = 0.032). Furthermore, the VEGF-1154 GG genotype was associated with inferior median OS compared with GA (hazards ratio = 1.68; 95% confidence interval: 1.10-2.57; P = 0.016) or with the alternative genotypes (GA and AA) combined (hazards ratio = 1.62; 95% confidence interval: 1.09-2.40; P = 0.017). In multivariate analysis, the VEGF-1154 GG genotype remained a significant adverse factor for OS. Our results support the potential predictive ability of VEGF genotypes in patients with metastatic colorectal cancer receiving irinotecan-based chemotherapy plus bevacizumab, in terms of RR and OS. However, current results should be validated prospectively, in larger cohorts.

The purpose of the present study was to investigate the prognostic role of severe hypoxemia on admission as an independent risk factor of pulmonary complications and mortality in patients with acute pancreatitis. Pulmonary complications were studied in 166 previously healthy patients with acute pancreatitis. Forty-eight patients (28.9%) developed one or more pulmonary complications, including pleural effusion, atelectasis, pulmonary consolidations, and acute respiratory distress syndrome (ARDS). Pulmonary consolidations (odds ratio = 7.25) and, especially, ARDS (odds ratio = 22.9) were significantly associated with severe baseline hypoxemia (PaO2, <60 mm Hg). Mortality was mainly related to severity of disease (odds ratio = 46.45), while hypoxemia was also found to be an independent risk factor of poor outcome (odds ratio = 9.56). It seems that, in patients with acute pancreatitis, severe hypoxemia on admission may be an early predictive marker of pulmonary complications, especially ARDS, and, independently of severity score, it may also be a marker of poor outcome.

One-hour docetaxel/carboplatin is a convenient, safe and effective outpatient palliative treatment for CUP patients, providing meaningful survival prolongation only in favourable-risk patients. Insights in the molecular biology of CUP are needed for the development of targeted therapeutic manipulations of malignant resistance and progression.

Vinorelbine and mitoxantrone have both been demonstrated to have significant antitumor activity in patients with breast cancer. The aim of this study was to evaluate the efficacy and safety of the combination as second or third line treatment in patients with metastatic breast cancer (MBC). Fifty-one previously treated patients with MBC were enrolled from October 2001 to May 2004 and 48 were eligible for evaluation. Median age was 59 years (range 33-82) and ECOG performance status was < or =2. Distant sites of metastasis were as follows: liver 64%, bone 49%, lung 36%, lymph nodes 6%, skin 4%, brain 2% and other sites 6%. All patients received vinorelbine 20 mg/m(2), D1+8 and mitoxantrone 10 mg/m(2) D8 every 21 days for 6 cycles. All eligible patients were analyzed for toxicity and response. Two patients (4%) achieved complete response and 12 (25.5%) partial response. The objective overall response rate was 29.5% (95% confidence interval [CI] 17 - 45), 9 (19%) patients had stable disease, 17 (36%) had progressive disease and 7 (15%) were non-evaluable. After a median follow up of 18 months, overall survival was 13 months (range 0.8 - 38+) and median time to disease progression was 5 months (range 1 - 32). A total of 280 cycles was delivered. The relative dose intensities of mitoxantrone and vinorelbine were 79% and 77%, respectively. Toxicities (grade III-IV) were as follows: leukopenia 18 (38%), neutropenia 21 (45%), thrombocytopenia 1 (2%), anemia 4 (8.5%), alopecia 2 (4%) and constipation 1 (2%). Febrile neutropenia was recorded in one patient. There were no treatment related deaths. The combination of mitoxantrone and vinorelbine is an effective regimen with manageable toxicity in pretreated patients with advanced breast cancer.

The aim of the study was to evaluate the association of vascular endothelial growth factor (VEGF) genotypes with treatment efficacy in a phase II trial. This study evaluated weekly docetaxel, as first-line treatment for metastatic breast cancer. Existing data from in vitro and animal model experiments suggest that docetaxel at low doses has anti-angiogenic activity. DNA was extracted from blood samples of 86 patients participating in the trial. Genotyping was performed for selected single-nucleotide polymorphisms (SNPs; VEGF-2578, -1498, -1154, and +936). Moreover, due to the highly polymorphic nature of the studied areas, we were able to analyze additional registered SNPs. All candidate genotypes were evaluated for associations with overall survival (OS), progression-free survival (PFS) and response rate. The VEGF-1154 GG genotype was more frequent in patients not responding to treatment compared with responders (42.9% vs 0.0%, P=0.048). Moreover, the VEGF-2578 AA genotype was associated with longer PFS compared with CC (hazard ratio (HR)=0.40; 95% confidence interval (CI) 0.17-0.98; pairwise P=0.0457). Patients with the VEGF-1190 GG genotype demonstrated shorter PFS compared with those with the alternative genotypes (GA and AA) combined (HR=3.85; 95% CI: 1.20-12.50; P=0.0224). In addition, the VEGF-2551/-2534 homozygous del18bp and VEGF-2430/-2425 homozygous ins1bp genotypes were associated with worse PFS compared with no deletion and no insertion, respectively (HR=2.49; 95% CI: 1.02-6.07; pairwise P=0.0442 and HR=2.57; 95% CI: 1.05-6.27; pairwise P=0.0385, respectively). Furthermore, patients with the VEGF-1498 CC genotype exhibited longer median OS compared with those with the alternatives genotypes (CT and TT) combined (HR=0.27; 95% CI: 0.08-0.89; P=0.0311). In multivariate analysis, the VEGF-2578 AA genotype retained its significance (P=0.0220) for PFS. Our results support the association of specific VEGF genotypes with clinical outcome in patients with metastatic breast cancer treated with a potentially anti-angiogenic regimen, such as weekly docetaxel. However, current results should be validated prospectively in larger cohorts.

Objectives Colorectal cancer (CRC) is the second leading cause of cancer in Europe, with 1.931.590 people newly diagnosed in 2020. The purpose of this study is the investigation of treatment options and healthcare resource metastatic CRC (mCRC) in Greece. Methods This study is based on the information collected in November 2020 by an expert panel comprising of 6 medical oncologists from major public and private centers around Greece. A 3-round survey was undertaken, according to Delphi method. The treatment phases studied were: pre-progression; disease progression and terminal care. Pharmaceutical costs and resource utilization data were considered from the perspective of the Greek National Services Organization (EOPYY). RESULTS: Experts agreed that the anticipated prevalence of RAS mutation in mCRC is 47% (30% RAS/BRAF WT Left, 17% RAS/BRAF WT Right); 8% BRAF while, MSI-H/dMMR are found in 5% of mCRC tumors. Based on mutational status, 74.8% of patients receive biological targeted therapies in combination with fluoropyrimidine/based combination chemotherapy, as 1st line treatment, and 25.2% combination chemotherapy alone. At 2nd line, 58.6% of patients receive biological targeted therapies in combination with chemotherapy, 25.4% immunotherapy, 11% combination chemotherapy and 5% biological targeted therapies. At 3rd line 56% of patients receive combination chemotherapy, 28% biological targeted therapies, 10% biological targeted therapies in combination with chemotherapy and 6% immunotherapy. The weighted annual cost (pharmaceuticals and resource use cost) in 1st line per mCRC patient was calculated at €28,407, in 2nd line €33,568, in 3rd line €25,550. The annual cost beyond 3rd line per patient regardless mutation was €19,501 per mCRC patient. Conclusions mCRC is a societal challenge for healthcare systems as the treatment is more prolonged but expand patients’ survival. Thus, reimbursement decisions should be based not just on the cost of the treatment, but on the magnitude of the benefit of its treatment on patients’ survival and quality of life.
