Background: The objective of this study was to compare Levovist power Doppler ultrasound (Levovist US) with contrast-enhanced spiral computed tomography (spiral CT), in the evaluation of the efficacy of percutaneous local ablation procedures, in patients with hepatocellular carcinoma (HCC)., Materials and Methods: Forty-six patients with 62 HCC were studied using Levovist US and triphasic spiral CT, after treatment by radiofrequency ablation (RFA) (32), percutaneous ethanol injection (PEI) (24), transarterial chemoembolization (TACE) (4), laser-therapy (LT) (1) and RFA plus TACE (1)., Results: Spiral CT scan showed contrast enhancement in 47% of the cases; at basal power Doppler ultrasound only 10% of the nodules showed to be vascular but, after Levovist infusion, 72.5% showed intralesional vascular spots., Conclusion: We detected that residual tumor vascularity in HCC, after treatment using percutaneous local ablation procedures, was significantly increased by Levovist. Levovist US could be proposed as a good alternative in patients unfit for CT scanning due to allergies to iodate contrast media, renal failure or cardiovascular disease and, moreover, could help to select those patients requiring a new treatment, without performing spiral CT, thereby reducing the cost of treatment and improving patient tolerance.

Background: Neoadjuvant chemotherapy for intermediate/high-grade soft tissue sarcomas (STS) may provide some advantages for facilitating the surgical resection of the tumor and for disease control. However its role as induction therapy before surgery should still be proved., Patients and Methods: Twenty-one patients with intermediate/high-grade STS and tumor size > or = 5 cm were consecutively treated from 1997 to 2001 with neoadjuvant chemotherapy based on epirubicin 60 mg/m2/day on days 1 and 2 and ifosfamide 1.8 gr/m2/day on days 1 through 5 every three weeks. Evaluation of objective tumor response and toxicity were carried out according to WHO criteria., Results: Nine partial responses were documented; stable disease in 11 patients, progressive disease in one patient. Apart from nine cases of grade 4 neutropenia, the treatment was generally well-tolerated. Twelve patients underwent conservative and limb salvage surgery., Conclusion: This therapeutic approach seems to be effective in facilitating surgery. Neutropenia was the most significant toxicity but it was preventable or medically treatable with G-CSF support.

The use of salvage chemotherapy in advanced non small cell lung cancer (NSCLC) is controversial. However, many patients need to be treated in order to achieve relief of their symptoms. Docetaxel (taxotere) is one of the most active drugs for the treatment of advanced NSCLC and several studies have also shown its effectiveness in pretreated patients. In the present study, 23 patients were treated in order to evaluate both the effectiveness and toxicity of the single agent docetaxel. Furthermore, granulocyte-colony stimulating (G-CSF) factor was administered in order to reduce neutropenia related to docetaxel. Docetaxel was administered intravenously at a dose of 100 mg/m2, on day 1, and it was repeated every 3 weeks. G-CSF was administered for primary prophylaxis of neutropenia at the standard dose of 30 mg/day from day 4 to day 10 of each cycle. The treatment was tolerated well and 5 (21.7%) partial responses were obtained. The median time to progression and the median survival time were 3 and 5 months, respectively. The main side effect noted was fatigue, the intensity of which was grade 2 in 43.4% of cases and grade 3 in 8.7% of patients, respectively. One patient (4.3%) had grade 4 cutaneous toxicity. No cases of grade 4 neutropenia were reported. In conclusion, docetaxel is active when used for salvage chemotherapy in advanced NSCLC whilst concurrent primary prophylactic administration of granulocyte-colony stimulating factor seems to decrease severe neutropenia.

Chemotherapy has been proposed for patients with hepatocellular carcinoma (HCC) associated with well-compensated cirrhosis who are unsuitable for locoregional treatments. Anthracyclines are the most active agents against HCC, although their toxicity is often unpredictable; thus, there is a need for new active drugs with a safe toxicity profile. The liposomal formulation of the anthracycline daunorubicin has low systemic toxicity and is taken up strongly by the liver. We started a phase I study with liposomal daunorubicin (starting dose 80 mg/m2 every 21 days) in patients with hepatocellular carcinoma and Child-Pugh stage A or B liver cirrhosis. At the starting dose, we recorded dose-limiting toxicities (1 hyperbilirubinemia, 1 prolonged prothrombin time, 1 persisting grade 3 neutropenia) in 3 out of 4 patients. Thus, according to protocol, we went down to the dose level of 60 mg/m2 but still 2 out of 3 patients had unacceptable toxicity (1 hypertransaminasemia, 1 hyperbilirubinemia with encephalopathia). Finally, we treated 4 more patients at the dose level of 40 mg/m2 and again we recorded liver toxicity in three of them. Overall haematological toxicity was mild and significant non-haematologic toxicities, other than hepatic, were not recorded. The toxicity profile observed warns against further assessment of liposomal daunorubicin in patients with hepatocellular carcinoma and liver cirrhosis.

Background: Although the use of salvage chemotherapy in advanced non-small cell lung cancer (NSCLC) is controversial, pretreated symptomatic patients often need some kind of treatment to achieve symptoms relief. Gemcitabine is one of the most active new drugs in advanced NSCLC and preliminary reports suggest that it is active also in patients previously treated with platinum compounds., Aim: to evaluate activity and toxicity and the effect on quality of life of gemcitabine in platinum-pretreated patients with advanced NSCLC., Methods: single-stage phase 2 trial with p0 = 5%, p1 = 20%, alfa = 5%, beta = 10%; 34 patients required and 4 objective responses expected to warrant further studies. Gemcitabine was administered at dose of 1000 mg/m2, i.v., d 18-15, every 4 weeks, for a maximum of 6 cycles. Quality of life was measured by EORTC C-30 and LC-13 questionnaires., Results: from September 1996 to July 1998, 30 patients have been enrolled. There were 6 (20% exact 95% CI 8-39%) partial responses (2 responses were in pts with brain metastases and 2 in patients progressed during first-line chemotherapy). All patients (but one died because myocardial infarction, progressed; median time to progression was 10 weeks (95% CI 7-12); 28 patients died; median survival was 22 weeks (95% CI 17-29). Quality of life analysis showed no significant change but for the improvement of cough after 3 cycles of chemotherapy. There was no severe toxicity., Conclusion: gemcitabine is active as second line for patients with advanced NSCLC who received platinum-based first line treatment. In view of such results randomized trials comparing gemcitabine versus best supportive care are warranted.

More than 30% of lung cancers arise in patients over 70 years old. Elderly patients are not considered to tolerate chemotherapy, are generally excluded from clinical trials, and are not considered eligible for aggressive cisplatinbased chemotherapy in clinical practice. The aims of the present study were to test the activity and toxicity of a combination of carboplatin and oral etoposide in patients over 70 years old with advanced non small cell lung cancer. Carboplatin was given at a dose of 300 mg/m2, i.v., at day 1, and oral etoposide (50 mg capsules) at a total dose of 100 mg/die from day 1 to day 7, recycled every 4 weeks. Fourteen patients entered the study. Median age was 73 years (range 70-77), 42.9% of patients had at least one concomitant illness. The trial, according to the Gehan design, was terminated earlier because no objective response was observed among the first 14 patients. We reported, according to intent to treat analysis, 2 stable and 12 progressive diseases. Median time to progression was 2 months and median survival 6 months. Remarkable hematological toxicity was recorded. Finally, we do not recommend the combination of carboplatin and oral etoposide, at the doses and schedule used in the present study, in the treatment of elderly patients with advanced NSCLC. The combination might be reconsidered using a different etoposide schedule with chronic administration (21 days).
