Phase II study of cetuximab in combination with FOLFIRI in patients with untreated advanced gastric or gastroesophageal junction adenocarcinoma (FOLCETUX study).

BACKGROUND: The purpose of this phase II study was to evaluate the efficacy and safety of cetuximab combined with FOLFIRI as a first-line treatment of advanced gastric or gastroesophageal junction (GEJ) adenocarcinoma. PATIENTS AND METHODS: Untreated patients with confirmed advanced gastric or gastroesophageal adenocarcinoma received cetuximab at an initial dose of 400 mg/m(2) intravenously (i.v.) followed by weekly doses of 250 mg/m(2), CPT 11 180 mg/m(2) i.v. on day 1, LFA 100 mg/m(2) i.v. followed by 5-FU 400 mg/m(2) i.v. bolus, and 600 mg/m(2) i.v. 22-h continuous infusion on days 1 and 2 (FOLFIRI) every 2 weeks, for a maximum of 24 weeks, then cetuximab alone was allowed in patients with a complete response, partial response, or stable disease. Antitumor activity was assessed by computed tomography (CT) and positron emission tomography (PET) at baseline and after 6 weeks, and further by CT alone or CT and PET every 6 weeks. RESULTS: Thirty-eight patients were enrolled (median age 63.5 years, range 39-83; median Karnofsky performance status 90, range 70-100; stomach 89.5% and GEJ 10.5%; locally advanced disease 13.2% and metastatic disease 86.8%). All 38 patients were assessed for safety and survival, and 34 patients were assessed for overall response rates (ORR). The ORR was 44.1% [95% confidence interval (CI) 27.5% to 60.9%]. The median time-to-progression was 8 months (95% CI 7-9). At the median follow-up time of 11 months, 55.3% of patients were alive, with a median expected survival time of 16 months (95% CI 9-23). Grade 3-4 toxicity included neutropenia (42.1%), acne-like rash (21.1%), diarrhea (7.9%), asthenia (5.3%), stomatitis (5.3%), and hypertransaminasemia (5.3%). There was one (2.6%) treatment-related death. CONCLUSIONS: The combination of cetuximab and FOLFIRI is active in gastric and GEJ adenocarcinoma. The higher toxicity appears to be limited to neutropenia.

Twice-daily pain monitoring as standard clinical practice for inpatients at a medical oncology unit: a descriptive study.

BACKGROUND: Very limited experiences have explored the use of pain intensity monitoring in everyday clinical practice at a medical oncology inpatient unit. METHODS: The program 'Pain-Free Hospital,' including a training course for nurses and the recording every 12 h of a visual analog scale (VAS) rating in all the patients admitted to the inpatients' ward independently of their disease stage, was activated in 2002. An audit on the clinical charts of patients admitted for the first time in the first semester of 2003 was carried out in order to ascertain the applicability of the procedure and its congruence with patients' clinical status. RESULTS: The VAS rating was reported in 211 out of 223 (94.6%) clinical charts. At entry, 60 out of 211 (28.4%) patients presented VAS>or=1, 21 (35%) of whom were not taking any analgesics. The mean VAS score>or=1 was 3.4. No statistically significant difference emerged in the distribution of VAS rating as regards disease extension, presence or absence of bone metastases and performance status. CONCLUSIONS: The systematic monitoring of VAS by nurses at a medical oncology inpatients' ward is feasible with a good patient compliance. The reliability of the procedure in terms of guiding the analgesic treatment has yet to be demonstrated.

Multicentre randomised phase III study comparing the same dose and schedule of cisplatin plus the same schedule of vinorelbine or gemcitabine in advanced non-small cell lung cancer.

This study compares two cytotoxic regimens comprising the same dose and schedule of cisplatin (CP) plus vinorelbine (VNR) or gemcitabine (GEM) administered under the same schedule to patients with advanced non-small cell lung cancers (NSCLC). From April 1998 to February 2003, 285 patients were randomised to receive either VNR 25 mg/m(2) on days 1 and 8 as an intravenous (i.v.) bolus plus CP 75 mg/m(2) on day 1 (regimen A) or GEM 1200 mg/m(2) on days 1 and 8 as an i.v. 30-min infusion plus CP 75 mg/m(2) on day 1 (regimen B). Both treatments were recycled every 21 days. If no progression had occurred after six cycles, the patients continued to receive VNR or GEM monochemotherapy weekly. Cross-over of the two single agents was considered if disease progression occurred. Objective response (OR), time to progression (TTP) and overall survival (OS) were analysed according to the intention-to-treat principle. 272 patients were ultimately eligible (137 on A and 135 on B). Their main characteristics were: male/female ratio 214/58; median age 63 (range 32-77) years; median Karnofsky Performance Status (PS) 80 (range 70-100); stage IIIB 34%, stage IV 61%, recurrent disease 5%; histology - epidermoid 29%, adenocarcinoma 53%, other NSCLC 18%. The characteristics of the patients in the two arms were well matched. The following response rates were observed in regimens A and B, respectively: complete response (CR) 0.7% and 3.7%, partial response (PR) 31.9% and 22.2% (P = 0.321). Median CR+PR duration was 8 months in both arms. Clinical benefit represented by an improvement in symptoms was evident in 25.7% and 28.1%, respectively. Median TTP was 5 months in both arms and median OS 11 months in both arms. Grade III-IV neutropenia occurred in 30.7% and 17.7% of the patients in arms A and B, respectively (P = 0.017); thrombocytopenia occurred in 0% and 9.3% (P = 0.004), respectively. No difference in the incidence of anaemia was observed. Non-haematological toxicity was generally mild: a higher incidence of grade 1-2 peripheral neurotoxicity and grade 1-2 local toxicity with regimen A and grade 1-2 liver toxicity with regimen B was reported. A pharmaco-economic comparison showed a difference between the two doublets, principally due to the different costs of VNR and GEM. Under the study conditions the combination of VNR or GEM with the same dose and schedule of CP produced similar OR, clinical benefits, TTP and OS in advanced NSCLC, and only mild toxicological differences were observed. Pharmaco-economic evaluation favoured the CP + VNR doublet.

Monitoring of heavy metal deposition in Northern Italy by moss analysis.

A survey of heavy metal deposition in the mountainous territories of Northern Italy was carried out in 1995-96. Moss samples (mainly Hylocomium splendens) were collected in a dense network of sites (about 3.2 sites/1000 km(2)) and the data of metal concentrations in moss tissues were statistically correlated with environmental and climatic factors, as well as with bulk deposition of elements and elemental concentrations in the soil. Three main geographic patterns of metal concentration in mosses could be defined: (1) Fe, Ni, and Cr, all derived both by soil particulates and anthropogenic emissions connected with ferrous metal manufacturing, were mostly concentrated in Northwestern Italy; (2) Cu and Zn, as typical multi-source elements, showed rather high concentrations with little ranges of variation over the whole area and small peaks reflecting local source points; (3) Cd and Pb reflected long-distance transport and showed highest concentrations in the regions with highest precipitation, especially in the Eastern Alps.
