The role of "closed abdomen" hyperthermic intraperitoneal chemotherapy (HIPEC) in the palliative treatment of neoplastic ascites from peritoneal carcinomatosis: report of a single-center experience.

PURPOSE: The purpose of this study was to review the results of a single-center experience in the management of "closed abdomen" hyperthermic intraperitoneal chemotherapy (HIPEC) using a sophisticated technical device (EXIPER®) in the palliative setting of neoplastic ascites from peritoneal carcinomatosis in patients with advanced cancer of different primary sites. PATIENTS AND METHODS: The study was an open, prospective, single-center, non-randomized study conducted at the Department of Medical Oncology 1, University of Cagliari, Italy, from May 2006 to October 2012. Fifteen patients with peritoneal carcinomatosis were treated with HIPEC: 5 males and 10 females (age range 51-82, median 62 years), for a total of 30 procedures (5 patients were treated more than once). Malignant ascites were from ovarian, uterine cervical, colorectal, gastric, malignant pleural mesothelioma, and unknown primary cancer. Main endpoints were increase of free interval between two consecutive procedures, progressive reduction of ascites volumes and improvement of quality of life assessed with ECOG performance status and EORTC QLQ-C30 questionnaire, and improvement of immunologic function. RESULTS: Twelve patients were completely evaluable while three patients were "lost" to follow-up. The treatment was well tolerated. The mean free interval between two consecutive drainages increased from 11.2 to 39.5 days. The mean ascites volume drained decreased from 7.8 to 1.8 l. ECOG PS improved in the majority of patients and EORTC QLQ-C30 scores in all patients as well as immunologic function. In September 2015, only one patient was still alive. CONCLUSIONS: Our study shows that good results may be achieved in terms of symptom palliation and improvement of quality of life in very advanced cancer patients with MA from PC. The treatment was generally well tolerated considering the limited treatment options available for these patients.

Muscle wasting as main evidence of energy impairment in cancer cachexia: future therapeutic approaches.

The present review aimed at discussing the impact, pathogenesis and therapeutic approaches of muscle wasting, which is a major clinical feature of cancer-related cachexia syndrome. The pathogenesis of muscle wasting in cancer cachexia lies in a discrepancy between anabolic and catabolic pathways mediated by chronic inflammation. Effective interventions specifically aimed at hampering muscle loss and enhancing muscle function are still lacking. Promising agents include anti-inflammatory, orexigenic and anabolic drugs, alongside with nutritional supplements that influence the STAT3 and PI3K/Akt/mTOR pathways involved in muscle wasting. Personalized physical activity combined with pharmacological and nutritional support hold promise. A greater understanding of the pathogenetic processes of cancer cachexia-related muscle wasting will enable the development of an early and effective targeted mechanism-based multimodal approach.

A randomized phase III clinical trial of a combined treatment for cachexia in patients with gynecological cancers: evaluating the impact on metabolic and inflammatory profiles and quality of life.

OBJECTIVES: Gynecological neoplastic disease progression is characterized by specific energy metabolism alterations and by symptoms including fatigue, anorexia, nausea, anemia, and immunodepression, which result in a cachexia syndrome and a marked decrease in patient quality of life (QoL). Therapeutic protocols associated with appropriate and effective psychological and social support systems are essential to counteract the symptoms of neoplastic disease in incurable patients. METHODS: A phase III randomized study was performed to establish the most effective and safest treatment to improve the key symptoms in advanced gynecological cancer patients, i.e., lean body mass (LBM), resting energy expenditure (REE), fatigue, and QoL. In addition, the impact of the treatment arms on the main metabolic and inflammatory parameters, including C-reactive protein (CRP), interleukin (IL)-6, tumor necrosis factor (TNF)-α, leptin, reactive oxygen species (ROS), and glutathione peroxidase, was evaluated. The change in the Glasgow Prognostic Score (GPS) during treatment was also assessed. A total of 104 advanced-stage gynecological cancer patients were enrolled and randomly assigned to receive either megestrol acetate (MA) plus l-carnitine, celecoxib, and antioxidants (arm 1) or MA alone (arm 2). The treatment duration was 4 months. RESULTS: The combination arm was more effective than arm 2 with respect to LBM, REE, fatigue, and global QoL. As for the secondary efficacy endpoints, patient appetite increased, and ECOG PS decreased significantly in both arms. The inflammation and oxidative stress parameters IL-6, TNF-α, CRP, and ROS decreased significantly in arm 1, while no significant change was observed in arm 2. CONCLUSIONS: The combined treatment improved both immunometabolic alterations and patient QoL. Multimodality therapies for cachexia ideally should be introduced within a context of "best supportive care" that includes optimal symptom management and careful psychosocial counseling.

The nutritional risk in oncology: a study of 1,453 cancer outpatients.

PURPOSE: There is little information about the nutritional status of cancer outpatients because the practice of nutritional screening is rarely performed. This study aims to define the pattern of scores of nutritional risk in 1,453 outpatients and factors associated with a high nutrition risk score, to facilitate the identification of such patients by the oncologists. METHODS: We prospectively screened the nutritional status of cancer outpatients according to the NRS-2002 score which combines indicators of malnutrition and of severity of the disease (1-3 points, respectively). A score ≥ 3 indicates "nutritional risk". The association of the nutritional scores with some patient/tumour/therapy-related variables was investigated through univariable and multivariable linear regression models. RESULTS: Thirty-two percent of outpatients were at nutritional risk. Primary tumour site, Eastern Cooperative Oncology Group score and presence of anorexia or fatigue were significantly associated with the nutrition risk score. Depending on the combination of these variables, it was possible to estimate different probabilities of nutritional risk. CONCLUSIONS: The frequency of a relevant nutritional risk was higher than expected considering the favourably selected population. The nutritional risk was associated with common clinical variables which are usually recorded in the charts and could easily alert the oncologist on the need of a further nutritional assessment or a nutritional support.

Definition and classification of cancer cachexia: an international consensus.

To develop a framework for the definition and classification of cancer cachexia a panel of experts participated in a formal consensus process, including focus groups and two Delphi rounds. Cancer cachexia was defined as a multifactorial syndrome defined by an ongoing loss of skeletal muscle mass (with or without loss of fat mass) that cannot be fully reversed by conventional nutritional support and leads to progressive functional impairment. Its pathophysiology is characterised by a negative protein and energy balance driven by a variable combination of reduced food intake and abnormal metabolism. The agreed diagnostic criterion for cachexia was weight loss greater than 5%, or weight loss greater than 2% in individuals already showing depletion according to current bodyweight and height (body-mass index [BMI] <20 kg/m(2)) or skeletal muscle mass (sarcopenia). An agreement was made that the cachexia syndrome can develop progressively through various stages--precachexia to cachexia to refractory cachexia. Severity can be classified according to degree of depletion of energy stores and body protein (BMI) in combination with degree of ongoing weight loss. Assessment for classification and clinical management should include the following domains: anorexia or reduced food intake, catabolic drive, muscle mass and strength, functional and psychosocial impairment. Consensus exists on a framework for the definition and classification of cancer cachexia. After validation, this should aid clinical trial design, development of practice guidelines, and, eventually, routine clinical management.

Efficacy and safety of oral lactoferrin supplementation in combination with rHuEPO-beta for the treatment of anemia in advanced cancer patients undergoing chemotherapy: open-label, randomized controlled study.

Advanced-stage cancer patients often suffer from anemia that closely resembles the anemia of chronic inflammatory diseases characterized by specific changes in iron homeostasis and absorption. i.v. iron improves the efficacy of recombinant human erythropoietin (rHuEPO) in anemic cancer patients undergoing chemotherapy. We report the results of an open-label, randomized, prospective trial aimed at testing the efficacy and safety of treatment with oral lactoferrin versus i.v. iron, both combined with rHuEPO, for the treatment of anemia in a population of 148 advanced cancer patients undergoing chemotherapy. All patients received s.c. rHuEPO-beta, 30,000 UI once weekly for 12 weeks, and were randomly assigned to ferric gluconate (125 mg i.v. weekly) or lactoferrin (200 mg/day). Both arms showed a significant hemoglobin increase. No difference in the mean hemoglobin increase or the hematopoietic response, time to hematopoietic response, or mean change in serum iron, C-reactive protein, or erythrocyte sedimentation rate were observed between arms. In contrast, ferritin decreased in the lactoferrin arm whereas it increased in the i.v. iron arm. In conclusion, these results show similar efficacy for oral lactoferrin and for i.v. iron, combined with rHuEPO, for the treatment of anemia in advanced cancer patients undergoing chemotherapy.

Randomized phase III clinical trial of five different arms of treatment in 332 patients with cancer cachexia.

PURPOSE: A phase III, randomized study was carried out to establish the most effective and safest treatment to improve the primary endpoints of cancer cachexia-lean body mass (LBM), resting energy expenditure (REE), and fatigue-and relevant secondary endpoints: appetite, quality of life, grip strength, Glasgow Prognostic Score (GPS) and proinflammatory cytokines. PATIENTS AND METHODS: Three hundred thirty-two assessable patients with cancer-related anorexia/cachexia syndrome were randomly assigned to one of five treatment arms: arm 1, medroxyprogesterone (500 mg/day) or megestrol acetate (320 mg/day); arm 2, oral supplementation with eicosapentaenoic acid; arm 3, L-carnitine (4 g/day); arm 4, thalidomide (200 mg/day); and arm 5, a combination of the above. Treatment duration was 4 months. RESULTS: Analysis of variance showed a significant difference between treatment arms. A post hoc analysis showed the superiority of arm 5 over the others for all primary endpoints. An analysis of changes from baseline showed that LBM (by dual-energy X-ray absorptiometry and by L3 computed tomography) significantly increased in arm 5. REE decreased significantly and fatigue improved significantly in arm 5. Appetite increased significantly in arm 5; interleukin (IL)-6 decreased significantly in arm 5 and arm 4; GPS and Eastern Cooperative Oncology Group performance status (ECOG PS) score decreased significantly in arm 5, arm 4, and arm 3. Toxicity was quite negligible, and was comparable between arms. CONCLUSION: The most effective treatment in terms of all three primary efficacy endpoints and the secondary endpoints appetite, IL-6, GPS, and ECOG PS score was the combination regimen that included all selected agents.

Protective effects of the angiotensin II receptor blocker telmisartan on epirubicin-induced inflammation, oxidative stress, and early ventricular impairment.

BACKGROUND: Oxidative stress and RAAS play an important role in the occurrence of anthracyclines-induced cardiotoxicity. Telmisartan, an angiotensin II type 1 receptor blocker, inhibits activation of superoxide sources and induces anti-inflammatory effects. METHODS: The possible role of telmisartan in preventing myocardial damage induced by epirubicin (EPI) was investigated. Forty-nine patients free from cardiovascular diseases affected by a variety of solid cancers were examined. Eligible patients were randomized to receive telmisartan (40 mg/d; TEL, n = 25) or placebo (PLA, n = 24) starting 1 week before chemotherapy. Patients were studied by means of echocardiography, tissue Doppler, and strain and strain rate (SR) imaging. We also measured plasma levels of inflammatory and oxidative stress markers. All parameters were assessed at baseline and 7 days after every new EPI dose of 100 mg/m(2). RESULTS: An impairment of the SR peak was observed at the EPI dose of 200 mg/m(2), with no significant differences between TEL and PLA (1.41 +/- 0.31 vs 1.59 +/- 0.36/s). At growing cumulative doses of EPI, SR normalized only in TEL, showing a significant difference in comparison to PLA at EPI doses of 300 mg/m(2) (1.69 +/- 0.42 vs 1.34 +/- 0.18/s, P < .001) and 400 mg/m(2) (1.74 +/- 0.27 vs 1.38 +/- 0.24/s, P < .001). Moreover, a significant increase in reactive oxygen species and interleukin-6 was found in PLA; but these remained unchanged in TEL. CONCLUSIONS: We confirmed that EPI-induced cardiotoxicity is primarily related to the inactivation of the cardiac antioxidant defenses. In addition, we showed that telmisartan can reduce EPI-induced radical species, antagonize the inflammation, and reverse the early myocardial impairment.

Cancer cachexia: medical management.

BACKGROUND: Cachexia is a complex metabolic syndrome associated with many chronic or end-stage diseases, especially cancer, and is characterized by loss of muscle with or without loss of fat mass. The management of cachexia is a complex challenge that should address the different causes underlying this clinical event with an integrated or multimodal treatment approach targeting the different factors involved in its pathophysiology. MATERIALS AND METHODS: The purpose of this article was to review the current medical treatment of cancer-related cachexia, in particular focusing on combination therapy and ongoing research. RESULTS: Among the treatments proposed in the literature for cancer-related cachexia, some proved to be ineffective, namely, cyproheptadine, hydrazine, metoclopramide, and pentoxifylline. Among effective treatments, progestagens are currently considered the best available treatment option for cancer-related cachexia, and they are the only drugs approved in Europe. Drugs with a strong rationale that have failed or have not shown univocal results in clinical trials so far include eicosapentaenoic acid, cannabinoids, bortezomib, and anti-TNF-alpha MoAb. Several emerging drugs have shown promising results but are still under clinical investigation (thalidomide, selective cox-2 inhibitors, ghrelin mimetics, insulin, oxandrolone, and olanzapine). CONCLUSIONS: To date, despite several years of co-ordinated efforts in basic and clinical research, practice guidelines for the prevention and treatment of cancer-related muscle wasting are lacking, mainly because of the multifactorial pathogenesis of the syndrome. From all the data presented, one can speculate that one single therapy may not be completely successful in the treatment of cachexia. From this point of view, treatments involving different combinations are more likely to be successful.

Oxytocin both increases proliferative response of peripheral blood lymphomonocytes to phytohemagglutinin and reverses immunosuppressive estrogen activity.

BACKGROUND: It has been shown that the neurohypophyseal peptide oxytocin is present in the human thymus and in vitro it can mimic interleukin (IL)-2 action in the induction of interferon-gamma production. In the present study, we tested the capacity of oxytocin to modulate the response of peripheral blood mononuclear cells (PBMCs) to phytohemagglutinin (PHA) and its ability to change the membrane expression of IL-2 receptor CD25 and the CD95 activation marker. Furthermore, whether oxytocin was able to reverse the inhibition of PBMC blastic response and CD25 expression induced by estradiol benzoate (E(2)B) was studied. PATIENTS AND METHODS: Fifteen healthy women were studied with a mean age of 33.8 years, no previous pregnancies, all in the early follicular phase of the cycle with normal values of circulating estrogens. RESULTS: The addition of oxytocin (1x10(-10) M, 1x10(-11) M, 1x10(-12) M) significantly increased the PBMC blastic response to PHA as well as the expression of both CD25 and CD95. These results were due to interaction of oxytocin with its specific receptor since the addition of an oxytocin antagonist completely reversed the oxytocin activity. In contrast, E(2)B induced a marked decrease of PHA-stimulated PBMC cell cycle progression and CD25 expression: the inhibitory effect of E(2)B was significantly counteracted by low concentrations of oxytocin. CONCLUSION: The present results support the hypothesis that neuropeptides may act as a link in the network between the immune and the neuroendocrine systems.

Interleukin-6 and leptin as markers of energy metabolic changes in advanced ovarian cancer patients.

The progression of the neoplastic disease is characterized by specific alterations of energy metabolism and by symptoms like fatigue, anorexia, nausea, anaemia, immunodepression and poor performance status (PS). The main cause of these symptoms and metabolic abnormalities is the chronic action of proinflammatory cytokines released both by tumour and immune cells. The present study aimed to assess the relationship between markers of inflammation (C-Reactive Protein, Fibrinogen, proinflammatory cytokines) and energy metabolic status (BMI, leptin, oxidative stress) according to clinical parameters in 104 ovarian cancer patients at different stage and, moreover, to evaluate prospectively the changes of these parameters in accordance to tumour response in a subgroup of 70 advanced stage ovarian cancer patients. Advanced stage and poor PS were associated to high-grade inflammation and impaired energy metabolism. Among inflammatory mediators, interleukin (IL)-6 had a central role as predictive factor of leptin, reactive oxygen species and glutathione peroxidase. In turn, leptin considered the key marker of the nutritional status and energy metabolism, was independently determined from stage and IL-6, not only from BMI. Moreover, the evaluation of the changes of these parameters during the course of the neoplastic disease in the subgroup of advanced ovarian cancer patients clearly unveils the central role of IL-6 and leptin as early markers of the metabolic alterations and symptoms associated to disease progression in advanced stage ovarian cancer. Their assessment should be included in monitoring disease outcome, especially when cancer is no longer curable and quality of life becomes the primary endpoint.

An attempt to correlate a "Multidimensional Geriatric Assessment" (MGA), treatment assignment and clinical outcome in elderly cancer patients: results of a phase II open study.

OBJECTIVES: To establish a correlation between a specific MGA category, an appropriate preventively established treatment and clinical outcome in a population of elderly cancer patients. The ultimate goal was to verify whether the appropriate treatment given to elderly cancer patients according to their MGA category could translate into a better clinical outcome assessed as clinical response and toxicity, i.e whether this process might achieve a clinically meaningful impact. PATIENTS AND METHODS: We carried out a phase II open, prospective non-randomized study in 75 elderly cancer patients (lung, head and neck, colorectal, gynecologic and breast) hospitalized at the Department of Medical Oncology, University of Cagliari, Italy. All patients underwent MGA evaluation and were assigned to three different categories: fit, intermediate and frail. Thereafter, an appropriate preventively established treatment was administered and the clinical outcome was assessed. The clinical outcome after 3 month treatment was defined on the basis of objective clinical response and toxicity. The difference of clinical outcome in the MGA categories was assessed by ANOVA test. Moreover, the correlation between MGA category and the clinical outcome (clinical response and toxicity) was assessed by Spearman's correlation test. RESULTS: A better clinical response was observed in fit patients as compared both to intermediate and frail patients. Treatment toxicity was comparable in the different MGA categories. The correlation analysis between MGA category, clinical response to treatment and toxicity showed that there was a significant direct correlation with clinical response and no correlation with toxicity. Overall, the regression analysis showed that MGA was predictive of clinical outcome, in the sense that it is truly predictive for clinical response and no predictive for toxicity. CONCLUSION: Our study demonstrates that the MGA, although time-consuming, is a useful and cost-benefit effective tool to appropriately select elderly cancer patients to be treated effectively in terms of a survival advantage and those who would benefit mainly in terms of improvement of quality of life. Moreover, the treatment preventively established for each MGA category was shown to be adequate and accomplished the most appropriate performances in terms of effectiveness and toxicity.

Persistence, up to 18 months of follow-up, of epirubicin-induced myocardial dysfunction detected early by serial tissue Doppler echocardiography: correlation with inflammatory and oxidative stress markers.

A phase II, open, nonrandomized trial was carried out in a group of epirubicin-treated cancer patients with the aim of detecting early preclinical changes that are predictive of the risk for heart failure. Thirty-one patients (male/female ratio, 8/23; mean age +/- standard deviation, 59 +/- 14 years) with tumors at different sites and scheduled to be treated with an epirubicin-based chemotherapy regimen, were enrolled. We prospectively evaluated the acute (1 week after) and late (3, 6, 12, and 18 months of follow-up) effects of epirubicin administration. A significant impairment in systolic left ventricular (LV) function was observed at a cumulative epirubicin dose of 200 mg/m(2). This was shown by a reduction in the strain rate (SR) peak in comparison with baseline and persisted throughout the treatment and follow-up, up to 18 months; strain (Sigma) remained unchanged. The Sm wave showed a progressive reduction that became significant only at the 18-month follow-up. On TDI the E(m)/A(m) ratio declined at the 200-mg/m(2) cumulative epirubicin dose versus baseline and persisted throughout the treatment and up to the 18-month follow-up. On conventional echocardiography the E/A ratio declined significantly only at the 300-mg/m(2) cumulative epirubicin dose. Interleukin (IL)-6, soluble IL-6 receptor, and reactive oxygen species (ROS) increased significantly at the 200-mg/m(2) dose, and IL-6 was persistently high at the 300- and 400-mg/m(2) doses, returning to within baseline values during follow-up. ROS, after the peak reached at the 200-mg/m(2) dose, returned to within baseline values. A significant inverse correlation between DeltaSR and the increase in both IL-6 and ROS was observed. A multiple regression analysis showed that both the IL-6 and ROS variables were independent and strongly predictive of DeltaSR. The clinical meaningfulness of our findings warrants further investigations on a larger number of patients for a longer period of follow-up.

A multicenter, phase II study of infliximab plus gemcitabine in pancreatic cancer cachexia.

To evaluate the safety and efficacy of infliximab administered with gemcitabine to treat cancer cachexia and to explore a functional measure of clinical benefit, investigators involved in this multicenter, phase II, placebo-controlled study randomized 89 patients with stage II-IV pancreatic cancer and cachexia to receive either placebo or 3 mg/ kg or 5 mg/kg of infliximab at weeks 0, 2, and 4 and then every 4 weeks to week 24; patients also received 1,000 mg/m2 of gemcitabine weekly from weeks 0-6 and then for 3 of every 4 weeks until their disease progressed. The primary endpoint was change in lean body mass (LBM) at 8 weeks from baseline; major secondary endpoints included overall survival, progression-free survival, Karnofsky performance status, and 6-minute walk test distance. In addition, quality of life was measured. The mean change in LBM at 8 weeks was +0.4 kg for patients receiving placebo, +0.3 kg for those receiving 3 mg/kg of infliximab, and +1.7 kg for those receiving 5 mg/kg of infliximab. No statistically significant differences in LBM or secondary endpoints were observed among the groups. Safety findings were similar in all groups. Adding infliximab to gemcitabine to treat cachexia in advanced pancreatic cancer patients was not associated with statistically significant differences in safety or efficacy when compared with placebo.

Randomized phase III clinical trial of five different arms of treatment for patients with cancer cachexia: interim results.

OBJECTIVE: In April 2005 a phase III randomized study was started to establish which was the most effective and safest treatment of cancer-related anorexia/cachexia syndrome and oxidative stress in improving identified primary endpoints: increase of lean body mass, decrease of resting energy expenditure (REE), increase of total daily physical activity, decrease of interleukin-6 and tumor necrosis factor-alpha, and improvement of fatigue assessed by the Multidimensional Fatigue Symptom Inventory-Short Form (MFSI-SF). METHODS: All patients were given as basic treatment polyphenols plus antioxidant agents alpha-lipoic acid, carbocysteine, and vitamins A, C, and E, all orally. Patients were then randomized to one of the following five arms: 1) medroxyprogesterone acetate/megestrol acetate; 2) pharmacologic nutritional support containing eicosapentaenoic acid; 3) L-carnitine; 4) thalidomide; or 5) medroxyprogesterone acetate/megestrol acetate plus pharmacologic nutritional support plus L-carnitine plus thalidomide. Treatment duration was 4 mo. The sample comprised 475 patients. RESULTS: By January 2007, 125 patients, well balanced for all clinical characteristics, were included. No severe side effects were observed. As for efficacy, an interim analysis on 125 patients showed an improvement of at least one primary endpoint in arms 3, 4, and 5, whereas arm 2 showed a significant worsening of lean body mass, REE, and MFSI-SF. Analysis of variance comparing the change of primary endpoints between arms showed a significant improvement of REE in favor of arm 5 versus arm 2 and a significant improvement of MFSI-SF in favor of arms 1, 3, and 5 versus arm 2. A significant inferiority of arm 2 versus arms 3, 4, and 5 for the primary endpoints lean body mass, REE, and MFSI-SF was observed on the basis of t test for changes. CONCLUSION: The interim results obtained thus far seem to suggest that the most effective treatment for cancer-related anorexia/cachexia syndrome and oxidative stress should be a combination regimen. The study is still in progress and the final results should confirm these data.

Timing of the negative effects of trastuzumab on cardiac mechanics after anthracycline chemotherapy.

Trastuzumab (TZB) has been shown to be extremely effective in breast cancer patients over-expressing HER-2, but careful cardiac monitoring is required when TZB is administered with anthracyclines, since the combination can increase its toxicity. Myocardial deformation indexes associated with speckle tracking echocardiography (STE) have proven to be very sensitive in identifying early myocardial dysfunction. An observational, prospective study was designed to assess TZB-induced cardiac damage using STE in patients with HER-2 positive breast cancer who had been sequentially treated with TZB following epirubicin (EPI). Conventional echocardiographic parameters and STE deformation indexes (longitudinal, radial, and circumferential strain/strain rate and apical rotation) were analyzed at baseline, after each EPI treatment, and 1 week after every other dose of TZB administration until 1 year follow up, in order to focus on the timing and extent of myocardial impairment. In the forty-five enrolled patients, a reduction in subendocardial function after EPI treatment was observed by a significant impairment of the global longitudinal strain/strain rate (GLS/SR), while a significant increase in the activity of the subepicardial fibers was highlighted by an increase in apical rotation. After the second TZB dose, a sudden reduction of the apical rotation was seen, together with circumferential and radial strain/SR. Most importantly, the extent to which the apical rotation increased and decreased was found to strictly correlate with the GLS reduction at follow up. We found that after EPI therapy, subendocardial function was impaired, even while a compensatory increase in apical rotation occurred. Following TZB treatment, we observed impairment in apical rotation, which seems to be the first sign of global LV dysfunction predicting GLS reduction found at the end of treatment.

Evaluation of the effectiveness of treatment with erythropoietin on anemia, cognitive functioning and functions studied by comprehensive geriatric assessment in elderly cancer patients with anemia related to cancer chemotherapy.

The primary aim of the present study was to examine the relationship of changes in hemoglobin levels following recombinant human erythropoietin (rHuEPO) treatment to changes in cognitive functioning studied by Mini Mental State Examination (MMSE) in elderly cancer patients undergoing chemotherapy treatment. The secondary aim was that to assess the relationship of changes in hemoglobin levels following rHuEPO treatment to changes in functions studied by Comprehensive Geriatic Assessment (CGA), such as Activity of Daily Living (ADL), Instrumental Activities of Daily Living (IADL), Geriatric Depression Scale (GDS) and the Mini Nutritional Assessment (MNA). To this end, hemoglobin levels and cognitive functioning were evaluated in a sample of cancer patients prior to the start of chemotherapy treatment and again after 4, 8 and 12 weeks of treatment with chemotherapy plus rHuEPO. Ten elderly patients (mean age 71.4 years) were enrolled. At baseline, enrolled patients had a mean Hb value of 10.3g/dl. After 4 weeks of rHuEPO treatment, Hb values increased significantly (p<0.0001), with a mean increase of 1.2g/dl (range: 0.2-2.1). Remarkably, 8 out of 10 (80%) showed an increase of Hb levels >or=1g/dl in comparison to baseline and therefore were considered responders. At baseline, four patients (40%) showed a moderate cognitive impairment, whilst six patients (60%) showed a normal cognitive function. After 4 weeks of rHuEPO treatment nine patients (90%) showed a significant improvement of cognitive functions in comparison to baseline (p<0.005): eight of them were responders also to rHuEPO in terms of correction of anemia. The Spearman's rank correlation test showed a statistical significant correlation between Hb increase and increase in cognitive functioning assessed by MMSE after 4 weeks (p=0.049), 8 weeks (p=0.044) and 12 weeks (p=0.031) of rHuEPO treatment. Therefore, the findings of this study provide support for the hypothesis that significant increases in hemoglobin over the course of chemotherapy supplemented with rHuEPO administration would be accompanied by significant improvement in cognitive performance over the same interval.

A phase II study with antioxidants, both in the diet and supplemented, pharmaconutritional support, progestagen, and anti-cyclooxygenase-2 showing efficacy and safety in patients with cancer-related anorexia/cachexia and oxidative stress.

PURPOSE: To test the efficacy and safety of an integrated treatment based on a pharmaconutritional support, antioxidants, and drugs, all given orally, in a population of advanced cancer patients with cancer-related anorexia/cachexia and oxidative stress. PATIENTS AND METHODS: An open early-phase II study was designed according to the Simon two-stage design. The integrated treatment consisted of diet with high polyphenols content (400 mg), antioxidant treatment (300 mg/d alpha-lipoic acid + 2.7 g/d carbocysteine lysine salt + 400 mg/d vitamin E + 30,000 IU/d vitamin A + 500 mg/d vitamin C), and pharmaconutritional support enriched with 2 cans per day (n-3)-PUFA (eicosapentaenoic acid and docosahexaenoic acid), 500 mg/d medroxyprogesterone acetate, and 200 mg/d selective cyclooxygenase-2 inhibitor celecoxib. The treatment duration was 4 months. The following variables were evaluated: (a) clinical (Eastern Cooperative Oncology Group performance status); (b) nutritional [lean body mass (LBM), appetite, and resting energy expenditure]; (c) laboratory [proinflammatory cytokines and leptin, reactive oxygen species (ROS) and antioxidant enzymes]; (d) quality of life (European Organization for Research and Treatment of Cancer QLQ-C30, Euro QL-5D, and MFSI-SF). RESULTS: From July 2002 to January 2005, 44 patients were enrolled. Of these, 39 completed the treatment and were assessable. Body weight increased significantly from baseline as did LBM and appetite. There was an important decrease of proinflammatory cytokines interleukin-6 (IL-6) and tumor necrosis factor-alpha, and a negative relationship worthy of note was only found between LBM and IL-6 changes. As for quality of life evaluation, there was a marked improvement in the European Organization for Research and Treatment of Cancer QLQ-C30, Euro QL-5D(VAS), and multidimensional fatigue symptom inventory-short form scores. At the end of the study, 22 of the 39 patients were "responders" or "high responders." The minimum required was 21; therefore, the treatment was effective and more importantly was shown to be safe. CONCLUSION: The efficacy and safety of the treatment have been shown by the study; therefore, a randomized phase III study is warranted.

Stop Flow in abdominal and pelvic cancer relapses.

To determinate MTD, DLT and safe doses for phase II study, a dose finding study with Mitomycin and Adriamycin Stop-Flow administration was carried out. A phase II study focused on resectability of pelvic colorectal relapses is in progress. From November 1995, 84 pts, 52 male and 32 female (94 treatments), with advanced not resectable abdominal (14 pts) or pelvic (70 pts) relapses, and resistant to previous systemic chemotherapy, were enrolled in the study. 46 pts entered the phase I-early phase II study, while subsequently 38 pts were recruited in ongoing phase II study. Safe dose were: MMC 20 mg/mq and ADM 75 mg/mq. The phase II study focused on colorectal relapses registered very promising responses: 90% pain control, 1 pCR and 26 PR / 63 (OR 43%), 8 NC (13%) 9/27 responder patients (33%) obtained a complete resectability of colorectal relapses. Stop-Flow is a safe and feasible technique very useful as a palliation treatment.

Feasibility of sequential therapy with FOLFIRI followed by docetaxel/cisplatin in patients with radically resected gastric adenocarcinoma. A randomized phase III trial.

OBJECTIVE: Combination therapies of fluorouracil (FU) with irinotecan (CPT-11) and docetaxel plus cisplatin have been proven to be active in metastatic gastric cancer. In this paper, we present the results of a phase III trial in which these two combinations given sequentially were compared to mitomycin C (MMC) monochemotherapy in an adjuvant setting. METHODS: 169 patients with radically resected gastric cancer were randomized to receive CPT-11 (180 mg/m2 day 1), leucovorin (100 mg/m2 days 1-2), FU (400-600 mg/m2 days 1-2, q 14; for four cycles; FOLFIRI regimen), followed by docetaxel (85 mg/m2 day 1), cisplatin (75 mg/m2 day 1, q 21; for three cycles; arm A), or MMC (8 mg/m2 days 1-2 as 2-hour infusion, q 42; for four cycles; arm B). All patients had histologically confirmed gastric carcinoma with nodal positivity or pT3/4. A total of 166 patients (85 in arm A and 81 in arm B) were treated. Adjuvant treatment was completed in 76% of the patients in arm A and in 70% of the patients in arm B. The main grade 3/4 side effects recorded were neutropenia in 35%, with only 1 febrile patient, and diarrhea in 11% in arm A, and thrombocytopenia in 10% and neutropenia in 7% in arm B. The FOLFIRI regimen and docetaxel/cisplatin given in sequence was well tolerated and feasible in adjuvant setting. This sequence treatment currently represents the experimental arm of an ongoing multicenter trial.
