Abstract
Hepatocellular carcinoma (HCC) on liver cirrhosis (LC) is a neoplasm with a poor prognosis. Only 10-36% of patients have resectable tumors at presentation, systemic chemotherapy is seldom useful and loco-regional treatments are feasible only in selected cases. On the basis of the possible role of depression of immune function in the pathogenesis of HCC on LC, we employed thymostimulin in the treatment of patients with unresectable HCC on LC, with the aim of influencing the course of the disease. Forty-six consecutive patients with HCC were enrolled from January 1987 to December 1993. All patients, 36 males and 10 females, with a median age of 67 years (range 58-82) had coexisting LC. All patients were treated with thymostimulin (TP-1 Serono) at doses of 70 mg/day i.m. five times a week until disease progression. Eleven patients achieved an objective response, with an overall response rate of 24%. Six patients obtained a CR (13.0%) with a median duration of 19+ months (range 5+/-23). Five patients (11%) achieved PR with a median duration of 10 months (range 7+/-22). Six patients (13.0%) presented MR (median duration: 12.5 months) and 12 (26.0%) had SD (median duration: 8 months). In 17 patients (36.9%) the disease progressed. Thymostimulin treatment was well tolerated and no major side effect was observed. Thymostimulin treatment can be considered a new promising therapy for advanced HCC.

Abstract
BACKGROUND To measure bone mineral density (BMD) reduction produced by letrozole as compared with tamoxifen and the benefit of the addition of zoledronic acid. PATIENTS AND METHODS A phase 3 trial comparing tamoxifen, letrozole or letrozole+zoledronic acid in patients with hormone receptor-positive early breast cancer was conducted; triptorelin was given to premenopausal patients. Two comparisons were planned: letrozole versus tamoxifen and letrozole+zoledronic acid versus letrozole. Primary end point was the difference in 1-year change of T-score at lumbar spine (LTS) measured by dual energy X-ray absorptiometry scan. RESULTS Out of 483 patients enrolled, 459 were available for primary analyses. Median age was 50 (range 28-80). The estimated mean difference (95% confidence interval [CI]) in 1-year change of LTS was equal to -0.30 (95% CI -0.44 to -0.17) in the letrozole versus tamoxifen comparison (P<0.0001) and to +0.60 (95% CI +0.46 to +0.77) in the letrozole+zoledronic acid versus letrozole comparison (P<0.0001). Bone damage by letrozole decreased with increasing baseline body mass index in premenopausal, but not postmenopausal, patients (interaction test P=0.004 and 0.47, respectively). CONCLUSIONS In the HOBOE (HOrmonal BOne Effects) trial, the positive effect of zoledronic acid on BMD largely counteracts damage produced by letrozole as compared with tamoxifen. Letrozole effect is lower among overweight/obese premenopausal patients.

Abstract
The aim of this study was to evaluate the effect of an oral glucose tolerance test (OGTT) on the level of endothelial dysfunction and vascular inflammation markers in healthy subjects (H) and diabetic overweight patients (D). We enrolled 256 healthy subjects and 274 type 2 diabetic patients. We evaluated blood glucose (BG), soluble intercellular adhesion molecule-1 (sICAM-1), interleukin-6 (IL-6), high-sensitivity C reactive protein (hsCRP), soluble vascular cell adhesion molecule-1 (sVCAM-1), soluble E-selectin (sE-selectin), and tumor necrosis factor-alpha (TNF-alpha) at baseline and after OGTT. We observed that BG, sICAM-1, IL-6, hs-CRP, sVCAM-1, sE-selectin, and TNF-alpha values were higher in D group than in H group. In a large sample of adult healthy subjects and type 2 diabetics we observed that both answer to an OGTT with a significant increase in biomarkers of systemic low-grade inflammation and endothelial dysfunction such as hsCRP, IL-6, TNF-alpha, sICAM-1, sVCAM-1, and sE-selectin. Type 2 diabetics experienced, however, a more significant increase in TNF-alpha, and sE-selectin.

Abstract
We evaluate the effect of a standardized dietary supplementation with omega-3 polyunsaturated fatty acids (n-3 PUFAs) on the level of some markers of vascular remodeling in patients with combined dyslipidemia. Three hundred and thirty-three patients received placebo or n-3 PUFAs for 6 months. We evaluated body mass index, glycemic profile, blood pressure, lipid profile, lipoprotein(a), plasminogen activator inhibitor-1, homocysteine, fibrinogen, high-sensitivity C reactive protein, ADP, MMP-2 and MMP-9, and tissue inhibitors of metalloproteinase-1 and -2. A significant increase of high-density lipoprotein-cholesterol, and a significant decrease of triglycerides were present after 3 and 6 months with n-3 PUFAs intake. A significant plasminogen activator inhibitor-1, fibrinogen and high-sensitivity C reactive protein decrease was obtained after 3 and 6 months and a significant ADP increase was observed after 3 and 6 months of n-3 PUFAs. A significant MMP-2, MMP-9, tissue inhibitors of metalloproteinase-1 and tissue inhibitors of metalloproteinase-2 decrease was obtained after 6 months compared to the baseline value with n-3 PUFAs intake. n-3 PUFAs give a better lipid profile and a better improvement of coagulation, fibrinolytic and inflammatory parameters than placebo. Furthermore, lowers levels of MMP-2, MMP-9 and their tissue inhibitors are obtained with n-3 PUFAs compared to placebo.

Abstract
Pyoderma gangrenosum is a rare, ulcerative, cutaneous condition. First described in 1930, the pathogenesis of pyoderma gangrenosum remains unknown, but it is probably related to a hyperergic reaction. There are various clinical and histological variants of this disorder. Pyoderma gangrenosum often occurs in association with a systemic disease such as inflammatory bowel disease, rheumatologic disease, paraproteinaemia, or haematological malignancy. The diagnosis, mainly based on the clinical presentation and course, is confirmed through a process of elimination of other causes of cutaneous ulcers. Local treatment may be sufficient for mild disease, while for severe cases, systemic immunosuppressants are the mainstay. Long-term treatment with these agents is often required, but this can expose patients to adverse side-effects.

Abstract #1150
Purpose. We compared the endocrine effects of 6 and 12 months of adjuvant letrozole versus tamoxifen in postmenopausal patients with hormone responsive early breast cancer, within an ongoing phase 3 trial (HOrmonal adjuvant treatment BOne Effects – HOBOE, ClinicalTrial.gov id: NCT00412022).
 Patients and Methods. Patients were randomised to receive tamoxifen or letrozole ± zoledronate. Serum values of 17-b-estradiol, FSH, LH, testosterone, dehydroepiandrosterone-solphate, progesterone, and cortisol were measured at baseline, after 6 and 12 months of treatment. For each hormone, baseline, 6 and 12-month values were compared between treatment groups, by the exact Wilcoxon-Mann-Whitney test.
 Results. At December 31, 2006, 157 postmenopausal patients had been enrolled into the study; baseline data were available for 139 patients (88.5%), 43 assigned to tamoxifen and 96 assigned to letrozole. Median age was 61 and 62 years in the two groups, respectively. Baseline values were similar between the two groups for all hormones. At 6 and 12 months, levels of 17-b-estradiol were significantly lower with letrozole as compared with tamoxifen (p=0.0003 and p<0.0001, respectively). Patients treated with letrozole also showed higher levels of progesterone and testosterone at 6 (p=0.001 and p=0.01, respectively) and 12 months (p=0.004 and p=0.02, respectively) than those treated with tamoxifen. FSH and LH were lower (all p<0.0001 for both hormones), while cortisol was higher (p=0.003 at 6 and 0.001 at 12 months) with tamoxifen than with letrozole.
 Conclusion. To our knowledge, this is the first study reporting on endocrine effects of letrozole as adjuvant treatment of postmenopausal early breast cancer and allowing a prospective comparison with tamoxifen. Adjuvant letrozole and tamoxifen result in significantly distinct endocrine effects. Such differences can explain the higher efficacy of letrozole as compared to tamoxifen. Long-term impact needs to be studied.

Abstract
The data reported in literature revealed a novel function for matrix metalloproteinases (MMPs) as modulators of adipogenesis. However, their expression profile and role in the cellular microenvironment during obesity-mediated adipose tissue development remain poorly defined. The authors hypothesized that MMP-2 and MMP-9 levels might be abnormal in obesity, reflecting alterations in extracellular matrix (ECM) turnover. One hundred and sixty three obese patients and 165 controls were enrolled. The following were measured: body mass index (BMI), waist circumference (WC), fasting plasma glucose (FPG), fasting plasma insulin (FPI), homeostasis model assessment (HOMA) index, systolic blood pressure (SBP), diastolic blood pressure (DBP), total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), triglycerides (Tg), lipoprotein(a) (Lp(a)), and plasma levels of MMP-2 and MMP-9. A significant increase of BMI and WC (p< .0001) was observed in obese patients. No FPG change was present in obese group, whereas FPI and HOMA index increases (p< .0001) were obtained in obese patients compared to control subjects. No SBP and DBP variations were observed in obese group. Significant TC and LDL-C increases (p< .0001) were present in obese patients, whereas no HDL-C, Tg, and Lp(a) changes were obtained in both groups. MMP-2 and MMP-9 levels were significantly higher in obese group (p< .0001). Plasma levels of MMP-2 and MMP-9 are increased in obese patients which may reflect abnormal ECM metabolism.

Abstract
578 Background: Few data have been reported on endocrine effects of combining LHRH-analogues with aromatase inhibitors (AI) in premenopausal patients. However, promising data in postmenopausal patients make this information interesting in view of extending adjuvant AI to premenopausal patients. We are conducting a phase 3 trial (Hormonal adjuvant treatment bone effects (HOBOE)) comparing tamoxifen (Tam), letrozole (L) and L + zoledronate (Z) for the effect on bone mineral density at 1 year. Postmenopausal and premenopausal patients are eligible, the latter also receiving monthly triptorelin (Tr). Methods: This analysis is limited to 76 premenopausal patients with early endocrine-responsive breast cancer, 28 treated with Tam+Tr and 48 with L+Tr±Z, assuming that Z has no endocrine effects. Serum 17-β-estradiol, FSH, LH, Δ4-androstenedione, testosterone, dehydroepiandrosterone-solphate, progesterone, ACTH and cortisol are measured at baseline and after 6 months of treatment. We compared, for each hormone, 6-month values between treatment groups by applying Exact Wilcoxon-Mann-Whitney test. Results: Baseline values for all the hormones were comparable between treatment groups. At 6 months, statistically significant differences were found for estradiol, FSH, LH and cortisol (see table , with median and range values by treatment group). No differences were found in plasma levels of testosterone, progesterone, ACTH, androstenedione, and dehydroepiandrosterone between the two groups. Conclusions: These data support that letrozole compared to tamoxifen, in combination with triptorelin, induces a more intense estrogen suppression also in premenopausal patients. Such evidence makes reasonable the hypothesis that the higher efficacy of letrozole versus tamoxifen shown in postmenopausal patients could be confirmed also in premenopausal patients.

Abstract
BACKGROUND AND OBJECTIVE Angiotensin II receptor blockers represent a class of effective and well-tolerated orally active antihypertensive drugs in the general hypertensive population and in diabetic patients. The aim of our study was to investigate the metabolic effects of telmisartan and irbesartan in diabetic subjects treated with rosiglitazone. METHODS We evaluated 188 type 2 diabetic patients with metabolic syndrome. All patients took a fixed dose of 4 mg rosiglitazone/day. We administered 40 mg telmisartan/day or 150 mg irbesartan/day and evaluated their body mass index, glycosylated haemoglobin (HbA(1c)), fasting plasma glucose (FPG), fasting plasma insulin (FPI), homeostasis model assessment-index (Homa-IR), total cholesterol (TC), low density lipoprotein-cholesterol (LDL-C), high density lipoprotein-cholesterol, triglycerides, systolic blood pressure, diastolic blood pressure, adiponectin and resistin during 12 months of this treatment. RESULTS AND DISCUSSION In addition to a comparable antihypertensive effect for telmisartan and irbesartan after 6 and 12 months, both treatments were associated with a significant reduction in TC and LDL-C plasma levels compared with baseline. After 6 months of treatment, only the telmisartan group experienced a significant improvement in (HbA(1c)), FPG, Homa-IR, adiponectin and resistin compared with the baseline values, whereas both drug regimens were associated with a significant improvement in these parameters after 12 months. However, the improvements observed in the telmisartan group were significantly larger than that noted in the irbesartan group after 12 months of treatment. FPI significantly decreased only after 12 months of treatment in both groups, but again, the reduction was significantly larger in the telmisartan-treated subjects. CONCLUSIONS Telmisartan seemed to improve glycaemic and lipid control and metabolic parameters of the metabolic syndrome better than irbesartan. These differences could be relevant in the choice of therapy for this condition and diabetes.

Abstract
Girdling effects on fruitlet abscission, leaf chlorophyll, chlorophyll a fluorescence and carbohydrate concentration in various flowering and vegetative shoots were studied during natural fruit drop in two Citrus cultivars. Irrespective of shoot type, girdling delayed fruitlet abscission, but only fruitlets borne on leafy shoots had increased final fruit set. Chlorophyll a fluorescence analysis revealed differences in quantum yield efficiency of photosystem II of light adapted leaves (Phi(PSII)) among shoot types and in response to girdling. In young leaves of vegetative shoots, girdling decreased Phi(PSII), whereas Phi(PSII) increased from Day 30 after girdling in young leaves of leafy flowering shoots; however, Phi(PSII) did not change in mature leaves during fruit set in either control or girdled trees. Girdling altered leaf carbohydrate concentrations and the photosynthetic performance of the various shoot types. Our results indicate that, in Citrus, several carbohydrate-based regulatory mechanisms of photosynthesis coexist during carbohydrate accumulation brought about by girdling. It is concluded that the delay in fruitlet abscission and the increase in Phi(PSII )observed in girdled leafy flowering shoots are the mechanisms underlying the enhancement of fruit set after girdling.

Abstract
BACKGROUND Metformin is considered the gold standard for type 2 diabetes treatment as monotherapy and in combination with sulphonylureas and insulin, whereas the combination of metformin with thiazolidinediones is relatively less studied. The aim of the present study was to assess the differential effect on glycaemic metabolism and lipid variables of the combination of metformin plus pioglitazone or metformin plus rosiglitazone in diabetic patients with metabolic syndrome. METHODS All patients began metformin and were randomized to receive pioglitazone or rosiglitazone for 12 months. We assessed body mass index, glycated haemoglobin, fasting plasma glucose, postprandial plasma glucose, fasting plasma insulin, postprandial plasma insulin, homeostasis model assessment index, total cholesterol, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, triglycerides, apolipoprotein A-I, and apolipoprotein B. RESULTS Significant decreases in glycated haemoglobin, fasting plasma glucose, postprandial plasma glucose, fasting plasma insulin, and postprandial plasma insulin were seen after 9 and 12 months in both groups. Homeostasis model assessment index improved at 12 months in both groups. Significant total cholesterol, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, triglycerides, apolipoprotein A-I, and apolipoprotein B improvement was observed in pioglitazone group after 12 months, but not in the rosiglitazone group. These variations were significant between groups. CONCLUSION The combination of metformin plus thiazolidinediones was able to improve glycaemic control compared with previous therapy. Pioglitazone was associated with a significant improvement in lipid and lipoprotein variables.

Abstract
BACKGROUND AND OBJECTIVE Metformin is considered the gold standard for type 2 diabetes treatment as monotherapy and in combination with sulphonylureas and insulin. The combination of metformin with thiazolidinediones is less well studied. The aim of the present study was to assess the differential effect, and tolerability, of metformin combined with pioglitazone or rosiglitazone on glucose, coagulation and fibrinolysis parameters in patients with type 2 diabetes mellitus and metabolic syndrome. METHODS This 12-month, multicentre, double-blind, randomized, controlled, parallel-group trial was conducted at three study sites in Italy. We assessed patients with type 2 diabetes mellitus (duration >or=6 months) and with metabolic syndrome. All patients were required to have poor glycaemic control with diet, or experienced adverse effects with diet and metformin, administered up to the maximum tolerated dose. Patients were randomized to receive either pioglitazone or rosiglitazone self-administered for 12 months. We assessed body mass index (BMI), glycaemic control [glycosylated haemoglobin (HbA(1c)), fasting and postprandial plasma glucose and insulin levels (FPG, PPG, FPI, and PPI respectively), homeostasis model assessment (HOMA) index], lipid profile [total cholesterol (TC), low-density lipoprotein-cholesterol (LDL-C), high-density lipoprotein-cholesterol (HDL-C) and triglycerides (TG)], lipoprotein (a) [Lp(a)] and homocysteine (HCT) at baseline and at 3, 6, 9 and 12 months of treatment. RESULTS AND DISCUSSION No BMI change was observed at 3, 6, 9 and 12 months in either group. Significant HbA(1c) decreases were observed at 9 and 12 months in both groups. After 9 and 12 months, mean FPG and PPG levels decreased in both groups. Decreases in FPI and PPI were observed at 9 and 12 months compared with the baseline in both groups. Furthermore, in both groups, the HOMA index improved but only at 12 months. Significant TC, LDL-C, HDL-C, TG improvement was present in the pioglitazone group at 12 months compared with the baseline values, and these variations were significantly different between groups. No TC, LDL-C, TG improvement was present in the rosiglitazone group after 12 months. Significant Lp(a) and HCT improvement was present in the pioglitazone group at 12 months compared with the baseline values, and Lp(a) change was significant compared with the rosiglitazone group. Significant HCT decrease was observed in the rosiglitazone group at the end of the study. In our type 2 diabetic patients, both drugs were safe and effective for glycaemic control and improving HCT plasma levels. However, long-term treatment with metformin plus pioglitazone significantly reduced Lp(a) plasma levels, whereas metformin + rosiglitazone did not. CONCLUSION For patients with type 2 diabetes mellitus and metabolic syndrome, combined treatment with metformin and rosiglitazone or pioglitazone is safe and effective, However, the pioglitazone combination also reduced the plasma Lp(a) levels whereas the rosiglitazone combination did not.

Abstract
The aim of the study was to demonstrate the superiority of docetaxel and epirubicin vs docetaxel alone as first-line therapy in metastatic breast cancer patients pretreated with adjuvant or neoadjuvant epirubicin. We compared single agent docetaxel 100 mg m-2 (D) with the combination of docetaxel 80 mg m-2 and epirubicin 75 mg m-2 (ED). The response rate (72 vs 79%), the progression-free survival (median 9 vs 11 months) and the overall survival (median 18 vs 21 months) were not significantly different between the ED (n=26) and D arms (n=25), respectively. Leucopaenia, nausea and stomatitis were significantly worse with ED. In conclusion, epirubicin should not be administered in combination with taxanes in metastatic breast cancer patients relapsed after an anthracycline-based adjuvant or neoadjuvant therapy.
