"Green Oncology": the Italian medical oncologists' challenge to reduce the ecological impact of their clinical activity.

For decades Western medicine has followed a biomedical model based on linear thinking and an individualized, disease-oriented doctor-patient relationship. Today this framework must be replaced by a biopsychosocial model based on complexity theory and a person-oriented medical team-patient relationship, taking into account the psychological and social determinants of health and disease. However, the new model is already proving no longer adequate or appropriate, and current events are urging us to develop an ecological model in which the medical team takes into account both individual illness and population health as a whole, since we are all part of the biosphere. In recent years, the rising costs of cancer treatment have raised a serious issue of economic sustainability. As the population of our planet, we now need to rapidly address this issue, and everyone of us must try to reduce their ecological footprint, measured as CO2 production. Medical oncologists need to reduce the ecological footprint of their professional activity by lowering the consumption of economic resources and avoiding environmental damage as much as possible. This new paradigm is endorsed by the Italian College of Hospital Medical Oncology Directors (CIPOMO). A working group of this organization has drafted the "Green Oncology Position Paper": a proposal of Italian medical oncology (in accordance with international guidelines) that oncologists, while aiming for the same end results, make a commitment toward the more appropriate management of health care and the careful use of resources in order to protect the environment and the ecosphere during the daily exercise of their professional activities.

Free drugs in clinical trials and their potential cost saving impact on the National Health Service: a retrospective cost analysis in Italy.

BACKGROUND: The cost of new anti-cancer drugs has dramatically increased in recent years, and countermeasures are required in order to limit pharmaceutical expenses. Sponsored clinical trials that provide drugs free of charge may be a useful tool in order to reduce drug costs. The aim of this analysis is to evaluate the effect of clinical trials on pharmaceutical expenditure savings. METHODS: We evaluated the cost of drugs administered in clinical practice and in clinical trials (considering only the standard regimens that were administered also in clinical practice) in 2010 at the Lung Cancer Unit of the National Institute for Cancer Research in Genoa, Italy. The cost of drugs was calculated on the price charged at our Institute in 2010. The supposed cost of experimental treatment replacing standard therapy was converted in the cost of the treatments that would have been chosen in clinical practice, considering histology, line of treatment and number of administered cycles. RESULTS: From 1/1/2010 to 12/31/2010, 196 patients affected by lung cancer or pleural mesothelioma were treated. 152 patients (78%) received treatment in clinical practice or in non-sponsored trials (18 patients in 4 trials), while 44 (22%) were treated in one of the 12 sponsored clinical trials recruiting in 2010. Globally, 606 cycles of treatment would have been administered to patients, of which 436 (72%) were administered in clinical practice or in non-sponsored trials and 170 (28%) were administered in pharmaceutical company sponsored clinical trials. The overall cost of those anti-neoplastic drugs, based on the prices charged at our Institute in 2010, was €799 803. The cost of drugs administered in clinical practice or in non-sponsored trials was €556 649 (70%), whereas the cost of standard drugs administered in clinical trials was €243 154 (30%). The grants provided by pharmaceutical companies were evaluated and amounted to €235 965. CONCLUSIONS: The participation in sponsored clinical trials in which drugs are provided free of charge offers substantial cost savings for the National Health Service; moreover, the grants received for each enrolled patient produced additional income.

Phase III trial of infusional fluorouracil, leucovorin, oxaliplatin, and irinotecan (FOLFOXIRI) compared with infusional fluorouracil, leucovorin, and irinotecan (FOLFIRI) as first-line treatment for metastatic colorectal cancer: the Gruppo Oncologico Nord Ovest.

PURPOSE: The Gruppo Oncologico Nord Ovest (GONO) conducted a phase III study comparing fluorouracil, leucovorin, oxaliplatin, and irinotecan (FOLFOXIRI [irinotecan 165 mg/m2 day 1, oxaliplatin 85 mg/m2 day 1, leucovorin 200 mg/m2 day 1, fluorouracil 3,200 mg/m2 48-hour continuous infusion starting on day 1, every 2 weeks]) with infusional fluorouracil, leucovorin, and irinotecan (FOLFIRI). METHODS: Selection criteria included unresectable metastatic colorectal cancer, age 18 to 75 years, and no prior chemotherapy for advanced disease. The primary end point was response rate (RR). RESULTS: A total of 244 patients were randomly assigned. An increase of grade 2 to 3 peripheral neurotoxicity (0% v 19%; P < .001), and grade 3 to 4 neutropenia (28% v 50%; P < .001) were observed in the FOLFOXIRI arm. The incidence of febrile neutropenia (3% v 5%) and grade 3 to 4 diarrhea (12% v 20%) were not significantly different. Responses, as assessed by investigators, were, for FOLFIRI and FOLFOXIRI, respectively, complete, 6% and 8%; and partial, 35% and 58%, (RR, 41% v 66%; P = .0002). RR confirmed by an external panel was 34% versus 60% (P < .0001). The R0 secondary resection rate of metastases was greater in the FOLFOXIRI arm (6% v 15%; P = .033, among all 244 patients; and 12% v 36%; P = .017 among patients with liver metastases only). Progression-free survival (PFS) and overall survival (OS) were both significantly improved in the FOLFOXIRI arm (median PFS, 6.9 v 9.8 months; hazard ratio [HR], 0.63; P = .0006; median OS, 16.7 v 22.6 months; HR, 0.70; P = .032). CONCLUSION: The FOLFOXIRI regimen improves RR, PFS, and OS compared with FOLFIRI, with an increased, but manageable, toxicity in patients with metastatic colorectal cancer with favorable prognostic characteristics. Further studies of FOLFOXIRI in combination with targeted agents and in the neoadjuvant setting are warranted.

Single-agent pegylated liposomal doxorubicin (Caelix) in chemotherapy pretreated non-small cell lung cancer patients: a pilot trial.

Polyethylene glycol-coated (pegylated) liposomal doxorubicin (PLD) is a new formulation of doxorubicin with peculiar pharmacokinetic and pharmacodinamic properties, a favorable toxic profile and a demonstrated activity in solid tumors. We tested PLD in locally advanced or metastatic NSCLC patients, progressed after a platinum-based first-line chemotherapy. PLD was administered at the dose of 35 mg/m(2) every 21 days. After the first six patients had been accrued, due to the low toxicity shown in the first six patients, the dose was escalated to 45 mg/m(2). Seventeen patients were enrolled in the study and were considered eligible for evaluation of toxicity and response. Stomatitis, palmar-plantar erythrodysaesthesia (PPE) and asthenia were the most common toxicities and affected approximately half of the treated patients. Stomatitis occurred in 8/17 patients and was grade 3-4 in three. PPE was seen in 9/17 and was grade 3 in one. In the group treated at the dose of 45 mg/m(2) PPE was more frequent and severe and required treatment delay in some cases. Other toxicities were equally distributed among the two groups. Hematological toxicity was not common and never reached grade 3-4. However, one patient with grade 2 leucopenia had pneumonia and died. Clinically evident heart failure was never recorded. Left ventricular ejection fraction was assessed in three patients after PLD treatment (in one case after the first course, due to the occurrence of atrial fibrillation, and in two cases after six courses) and was unchanged compared to pre-treatment assessment. One confirmed partial response was observed (5.8%); five patients (29.4%) had stable disease (including one minor response) and nine (52.9%) had disease progression. Median time to progression was 9.5 weeks, median survival 18.6 weeks. PLD at the doses employed in this study can be safely administered and has shown activity in platinum pretreated NSCLC patients.
