RESUMO

BACKGROUND AND PURPOSE: Stereotactic Ablative Radiotherapy (SABR) is emerging as a valid alternative to surgery in the oligometastatic setting in soft tissue sarcomas (STS), although robust data are lacking. The aim of this study is to evaluate toxicity and efficacy of SABR in oligometastatic STS. MATERIALS AND METHODS: This is a retrospective multicenter study including adult patients affected by stage IV STS, treated with SABR for a maximum of 5 cranial or extracranial metastases in up to 3 different organs. SABR was delivered with ablative purposes. Study endpoints were overall survival (OS), local control (LC), distant progression free survival (DPFS), time to polymetastatic progression (TTPP), time to new systemic therapy (TTNS) and toxicity. RESULTS: From 10 Italian RT centers, 138 patients (202 metastases) treated between 2010 and 2022 were enrolled in the study. Treatment was generally well tolerated, no acute or late toxicity ≥ G3 was recorded. Median follow up was 42.5 months. Median OS was 39.7 months. Actuarial OS at 1 and 2 years was 91.5 % and 72.7 %. Actuarial LC at 1 and 2 years was 94.8 % and 88.0 %. Median DPFS was 9.7 months. Actuarial DPFS at 1 and 2 years was 40.8 % and 19.4 %. CONCLUSION: SABR is a safe and effective approach for the treatment of oligometastatic sarcoma. One out of 5 patients is free of progression at 2-years.

RESUMO

AIM: To evaluate the efficacy of stereotactic body radiotherapy (SBRT) for spine oligometastases. MATERIALS AND METHODS: This was a multicentre retrospective study of a series of patients who received SBRT for spine oligometastases. The efficacy of SBRT was evaluated in terms of local control as the primary endpoint. Survival outcomes were also analysed to identify predictive factors for clinical outcomes. Toxicity was assessed according to CTCAE v4.0. RESULTS: Between March 2018 and July 2022, 183 lesions in 177 patients were analysed. In most patients, SBRT was delivered to a single spine metastasis (82%) for a median total dose of 21 Gy (14-35 Gy) in three fractions (one to five fractions) and a median BED10 = 119 Gy (57.7-152 Gy). Local control rates were 90.3% at 1 year, 84.3% at 2 years and 84.3% at 3 years. Distant progression-free survival rates were 33.1%, 18.5% and 12.4% at 1, 2 and 3 years, with prostate histology (P = 0.023), oligorecurrent disease (P = 0.04) and BED10 > 100 Gy (P = 0.04) found to be predictive on univariate analysis. A further oligometastatic progression was observed in 33 patients (18.6%) treated with a second course of SBRT, reporting at univariate analysis improved overall survival rates (P = 0.01). Polymetastases-free survival rates were 57.8%, 43.4% and 32.4%; concurrent therapy was related to improved outcomes at multivariate analysis (P = 0.009). Overall survival rates were 91.8%, 79.6% and 65.9%, with prostate histology and non-cervical metastases related to better overall survival at multivariate analysis. Pain-flare after SBRT was recorded in 3.3%; five patients underwent surgical decompression after SBRT; there were no grade ≥3 adverse events. CONCLUSIONS: In our experience of only oligometastatic patients, spine SBRT gave excellent results in terms of safety and efficacy. Prostate histology and oligorecurrent disease were predictive factors for improved clinical outcomes; also, patients who experienced a further oligoprogression after SBRT maintained a survival advantage compared with polymetastatic progression. No severe adverse events were reported.

RESUMO

Introduction: Best care of esophagogastric junction and gastric cancer (EGC) requires a complex, timely interaction between members of a multi-disciplinary team (MDT). An integrated clinical pathway (ICP) is necessary to achieve this goal as well as the implementation of its use in daily practice. The objective of this study was to elaborate on an integrated clinical pathway for the multi-disciplinary management of ECG. Authors also put in act an implementation program to improve adherence to guidelines thought an ICP. Method: This prospective work carried out by a multi-institutional MDT in Italy identified expert panel extracted relevant recommendations and/or statements from published papers and guidelines obtaining a set of crucial interventions employed the Estimate-Talk-Estimate method. A flow-chart diagram was elaborated to elicit the process at a glance. The primary outcome measure was the elaboration of an ICP with a high consensus rate also reported as a snapshot diagram and its implementation in daily clinical practice. An accredited certification body agency validated results, and an implementation process was started in several hospitals known to treat ECG. Results: A methodologist aggregated a multi-disciplinary panel of experts from different institutions. The panel elaborated a flow-chart diagram with crucial intervention highlight and connecting lines, as well as outcome measures. An accredited certification body agency validated the entire process, representing the basis for empowerment and implementation among patients and oncological professionals in various hospitals. Conclusion: The multi-disciplinary and multi-institutional expert panel successfully elaborated on a validated ICP for all stages ECG. An in-hospital implementation program has been programmed.

RESUMO

INTRODUCTION: Stereotactic ablative radiotherapy (SABR) has been shown to increase survival in oligometastatic disease, but local control of colorectal metastases remains poor. We aimed to identify potential predictive factors of SBRT response through a multicenter large retrospective database and to investigate the progression to the polymetastatic disease (PMD). MATERIAL AND METHODS: The study involved 23 centers, and was approved by the Ethical Committee (Prot. Negrar 2019-ZT). 1033 lung metastases were reported. Clinical and biological parameters were evaluated as predictive for freedom from local progression-free survival (FLP). Secondary end-point was the time to the polymetastatic conversion (tPMC). RESULTS: Two-year FLP was 75.4%. Two-year FLP for lesions treated with a BED < 00 Gy, 100-124 Gy, and ≥125 Gy was 76.1%, 70.6%, and 94% (p = 0.000). Two-year FLP for lesion measuring ≤10 mm, 10-20 mm, and >20 mm was 79.7%, 77.1%, and 66.6% (p = 0.027). At the multivariate analysis a BED ≥125 Gy significantly reduced the risk of local progression (HR 0.24, 95%CI 0.11-0.51; p = 0.000). Median tPMC was 26.8 months. Lesions treated with BED ≥125 Gy reported a significantly longer tPMC as compared to lower BED. The median tPMC for patients treated to 1, 2-3 or 4-5 simultaneous oligometastases was 28.5, 25.4, and 9.8 months (p = 0.035). CONCLUSION: The present is the largest series of lung colorectal metastases treated with SABR. The results support the use of SBRT in lung oligometastatic colorectal cancer patients as it might delay the transition to PMD or offer relatively long disease-free period in selected cases. Predictive factors were identified for treatment personalization.

RESUMO

OBJECTIVE: The objectives of this review are to explore the neuronal pathways and cellular and molecular mechanisms involved in both healthy and impaired cognitive function and to discuss the role of nootropics, in particular, those with cholinergic activity, as promising interventions to preserve and/or improve cognitive performance in patients in the symptomatic pre-dementia stage, known as mild cognitive impairment (MCI). MATERIALS AND METHODS: Papers were retrieved by a PubMed search, using different combinations of keywords (e.g., cognitive function AND aging AND nootropics), without limitations in terms of publication date or language. RESULTS: Nootropics modulate the activities of specific brain pathways involving neurotransmitters and neuromodulators that have distinct roles in the cognitive processes. The nootropic L-a-glyceryl-phosphoryl-ethanolamine (L-a GPE), by virtue of its action as a phospholipid (PL) precursor and acetylcholine (Ach) donor, targets neural stem cell aging, cholinergic depletion, oxidative stress and microglia activation, loss of entorhinal cortex neurons, and reduced hippocampal volume. Cognitive reserve levels may be linked to the resilience and adaptability of the brain to cope with age-related cognitive decline. L-a GPE may contribute to cognitive reserve preservation via its neuronal well-being promoting action. CONCLUSIONS: The substantial burden of age-related cognitive decline demands effective long-term and well-tolerated interventions aimed at maximizing the span of effective functioning. The use of inappropriate medication may lower cognitive reserve, thus hastening the onset of symptomatic AD, while the use of nootropics, such as L-a GPE may contribute to cognitive reserve preservation via its neuronal well-being promoting action.

RESUMO

Chronic hepatitis is often associated with neuropsychiatric disorders. Interferon (IFN) is the drug most widely used to treat this disease, and its side effects, such as depression, often involve the central nervous system (CNS). Symptoms include a slowing down of psychomotor functions, loss of interest, frontal lobe dysfunction, parkinsonism, and delirium. The occurrence of these complications calls for dropping out of IFN treatment or for a significant dose reduction and administration of antidepressants. Efficacy and side effects vary on the basis of the IFN type employed. The aim of our study was to evaluate if the frequency, form, and degree of depression induced are related to the type of IFN employed. We studied 96 patients with chronic hepatitis C. Our study series was divided into four groups according to the type of IFN-alpha administered. Depression degree was clinically evaluated using the Hamilton Depression Rating Scale (HAM-D). All patients were tested before treatment and 1, 3, and 6 months (15 days after the end of treatment) later. Our results showed that the type of IFN used seemed to influence the depression onset rate, with the leukocyte type inducing the lowest level of depression. However, when a number of symptoms associated with the depression were considered, the results of other types of IFN-alpha were found to be better. Use of the most suitable type of IFN-alpha could thus lead to more personalized treatment, with fewer side effects. The type of IFN used seems to influence the psychological side effects and the adaptation rate to therapy. It would be appropriate to choose the type of IFN on the basis of a neuropsychiatric assessment carried out before treatment.

RESUMO

BACKGROUND: Expansion of the current program of national sharing of cadaveric kidney allografts is of uncertain benefit, and the logistical barriers to expanding organ sharing are large. This study estimated the improvement in allograft survival from expanding organ sharing in the United States. METHODS: A decision analysis based on allograft survival data from cadaveric allograft recipients throughout the United States compared the mean allograft survival resulting from four allograft-sharing strategies: no national sharing, national sharing of allografts matched at 6 histocompatibility alleles, national sharing of allografts matched at 4 or more alleles, and national sharing of allografts matched at 2 or more alleles. RESULTS: Sharing allografts matched at 4 or more alleles was optimal (mean allograft survival=6.35 years). This survival was little better than the mean survival of the other three strategies (no national sharing, 6.21 years; national sharing of allografts matched at 6 alleles, 6.31 years; and sharing of allografts matched at 2 or more alleles, 6.33 years). The increment in the proportion of allografts surviving 4 years or more under the optimal strategy compared with no national sharing was <2%. A similar decision model comparing kidney transplant outcomes before and after the introduction of cyclosporine showed that this drug has had a much greater impact on mean allograft survival than would be expected to occur with national allograft sharing: 6.07 years with cyclosporine versus 3.79 years without cyclosporine. CONCLUSIONS: Expanding national allograft sharing would achieve little improvement in mean allograft survival. The limited benefit and logistical barriers to expansion of allograft sharing should be considered before following recommendations to expand the current U.S. allograft-sharing program.

RESUMO

OBJECTIVE: Our study was designed to evaluate the role of omega-3 fatty acids (OFAs) in reducing serum triglyceride levels in patients with chronic hepatitis C receiving treatment with interferon-alpha (IFNalpha). DESIGN: 52 patients (23 males, 29 females) with chronic hepatitis C were randomly assigned to nonblind treatment with IFNalpha 3 million units (MU) three times weekly alone (group A) or in combination with OFAs 3 g/day for 6 months (group B). RESULTS: Hepatitis C virus (HCV) RNA serum levels decreased significantly in both groups compared with baseline, but there was no significant difference in HCV RNA levels between the 2 groups. At the end of treatment there was a statistically significant difference in ALT levels between patients in group A and in group B (72.15 vs 50.05 IU/L; p = 0.01). A statistically significant increase in triglyceride levels occurred in group A during treatment (p = 0.03 vs baseline). In contrast, a statistically significant decrease in triglyceride serum levels occurred in group B (p = 0.001 vs baseline). CONCLUSION: Concurrent administration of OFAs reversed IFNalpha-induced hypertriglyceridaemia in patients with chronic hepatitis C.

RESUMO

OBJECTIVE: Chronic liver disease is often a hypocarnitinaemic condition. Since carnitine affects lipid metabolism, modifications of lipid pattern and energy metabolism can be expected in patients affected by chronic viral hepatitis. The aim of this study was to assess the relationship between serum carnitine levels and the grading of chronic hepatitis C, and to evaluate the effects of lymphoblastoid interferon (IFN)-alphan1 on carnitine levels in patients with hepatitis C. DESIGN: We evaluated carnitine serum levels in a group of 32 patients with chronic hepatitis C before and after treatment with intramuscular IFNalpha 3MU 3 times/week for 6 months, comparing them with levels in 20 healthy controls. Statistical correlations between serum carnitine, histological activity index score, duration of disease and lipid pattern were also evaluated. RESULTS: Serum carnitine levels, which were statistically lower in hepatitis C patients than in controls before therapy, increased after IFNalpha (p = 0.0003 vs pretreatment). There were no significant changes in total cholesterol in any patient after treatment, although serum triglyceride levels increased (p = 0.0003). Serum carnitine levels were correlated with age (r = 0.35; p = 0.02), type of response (r = - 03; p = 0.04), duration of disease (r = - 0.8; p = 0.0001) and high-density lipoprotein cholesterol levels (r = 0.43; p = 0.005) after completion of IFNalpha treatment. CONCLUSION: It is suggested that the post-treatment increase in serum carnitine observed in this study could be considered a new index of improved liver function. Also, exogenous administration of carnitine may be useful in patients with chronic hepatitis C who have reduced endogenous synthesis of this substance.

RESUMO

Interleukin 6 (IL-6) is a pleiotropic cytokine produced by a wide variety of lymphoid and non-lymphoid tissues. We studied the relationship between IL-6 and the liver in an attempt to elucidate this cytokine's role in hepatitis C-induced liver inflammation. We investigated the behavior of serum IL-6 in 25 patients with chronic hepatitis C (divided into three groups depending on severity) and in 27 healthy controls. Our results showed a significant elevation (P < 0.0001) in serum IL-6 levels in the patients with chronic hepatitis C, correlated with the histological activity index (HAI) and their HCV-RNA serum levels. This rise may represent the expression of the hepatitis C virus-induced inflammatory state.

RESUMO

OBJECTIVE: HLA antigens influence tumour growth and spreading, but the mechanism is still unclear. Increased serum levels of beta2-microglobulin (beta2MG) have been found in several chronic inflammatory and tumour diseases. The aim of the present study was to analyse the relationship between serum beta2MG levels and some markers of tumour progression, to verify the reliability of this parameter as a marker of hepatocellular carcinoma (HCC) progression. DESIGN: We studied 50 patients with hepatitis C virus (HCV) correlated HCC, 50 patients affected by chronic hepatitis C and 20 healthy controls. We performed a statistical analysis on the data obtained from haematological withdrawals in patients and healthy subjects. METHODS: Serum beta2MG levels were determined by an immunoturbidimetric method (normal values range from 0.8 to 27 microg/ml). Diagnosis of HCC was performed on the basis of haematochemical parameters (alpha-fetoprotein) and instrumental examinations (ultrasonography and computed tomography). In order to perform the statistical analysis we used the Wilcoxon non-parametric rank test and the Spearman log-rank correlation test RESULTS: Patients with HCC showed higher serum beta2MG levels than did chronic hepatitis C patients (36+/-16.5 microg/ ml versus 2.3+/-0.8 microg/ml; P<0.0001) or healthy subjects (36+/-16.5 microg/ml versus 1.6+/-0.4 microg/ml; P<0.0001). We found a positive correlation between beta2MG and interleukin-6 (IL-6) (r = +0.3; P = 0.05), beta2MG and alpha-fetoprotein (r = +0.4; P = 0.005), beta2MG and tumour size (r = +0.3; P = 0.02). CONCLUSIONS: An increase in the beta2MG serum level reflects the tumour size and seems to be a consequence of the stimulation on hepatocytes by humoral components of immunological response, such as IL-6. Weakening of the immune system, due to IL-6, may be responsible for a more severe progression of HCC and the hyperexpression of beta2MG.

RESUMO

Cytokines can play a crucial role in defending the organism from viral infections. One of these, interferon gamma (IFN-gamma), possesses marked immunomodulating activity. As cell immunity seems to be involved in chronic hepatitis C virus (HCV), study of the events regulated by IFN-gamma may be useful in evaluating the host's immunological response. We studied 63 patients (36 males, 27 females) affected by chronic HCV and 28 (14 males, 14 females) healthy controls. IFN-gamma concentrations were significantly lower in the former, and were positively correlated with the histological activity index, suggesting that low IFN-gamma values play a part in determining chronicity. We believe they may be an unfavorable factor and may be useful in detecting patients who are not capable of eradicating the virus.

RESUMO

A 62-year-old man, affected by Chronic Active Hepatitis (discovered in 1993) and treated with interferon, referred to our department with increased abdominal volume, persistent abdominal pain, continuous-remittent fever and jaundice. CT scan of the liver revealed a hypodense, not capsulated, infiltrative, solid formation in the right lobe. US guided biopsy showed multinucleated giant cells, with eosinophilic cytoplasm and pleomorphism of the nuclei, arranged in several thick trabecula lined by endothelial cells or formed bile containing acini. In our case, the rapid evolution of chronic viral hepatitis towards HCC calls for a careful evaluation of the role of IFN therapy, since this drug is widely used in chronic liver diseases.

RESUMO

BACKGROUND: A more prolonged life expectancy is associated with an increased morbidity rate with marked alterations of physiologic and metabolic functions in the body. The haematologic pattern can be modified during ageing because of reduced cellular replication and enhanced fibrosis in the bone marrow. Nevertheless it is not clear whether ageing represents the cause or the result of these phenomena. METHODS: In order to evaluate wide variation of data on the haematologic pattern in elderly subjects, we studied one hundred eight healthy subjects (27 males, 81 females; ranging from 50 to 99 years), living in their home. RESULTS: We observed a reduction in serum iron and transferrin and an increase in serum ferritin levels during ageing, with a consequential iron tissue stores increase. CONCLUSIONS: Our data suggested that senescence was associated with an increased incidence of anemia, which cannot be considered a normal feature of aging, the physicians must investigate each cause of anemia in elderly subjects. Haematological pattern is in the normal range in healthy elderly subjects, even if we found significant age-linked changes. We conclude that a progressive impairment of bone marrow functions is the most important factor in determining significant changes of hematopoiesis in healthy elderly subjects.

RESUMO

Interleukin-6 (IL-6) is a pleiotropic cytokine involved in numerous diseases but the correlation between liver fibrosis and IL-6 role is not clear. We studied IL-6 levels in 50 HCVAb+ patients with liver cirrhosis (grouped into A, B and C, Child classes) and in 27 healthy control subjects. IL-6 serum levels were significantly increased in the former (p < 0.005) suggesting that IL-6 stimulates and sustains liver fibrosis. In cirrhotic subjects, the rise in IL-6 serum levels is due to impaired hepatic clearance of this cytokine, while its production remains steady.

RESUMO

IFN-alpha represents the treatment of choice in chronic hepatitis C. It acts directly on the cells infected by the virus and indirectly via the cytokine network. We studied the behavior of interleukin 6 (IL-6), a cytokine that is particularly active in the liver and considered an index of liver inflammation and necrosis, in order to evaluate the relationships between IFN-alpha administration and serum levels of this cytokine. Our study series was composed of 60 patients (32 males, 28 females, mean age 53.03 +/- 12.7 years) affected by chronic hepatitis C and 24 healthy controls (14 males, 13 females, mean age 45.8 +/- 5.9 years). We determined serum IL-6 concentrations before and after 3,000,000 IU of IFN-alpha t.i.w./6 months in the former and compared them with levels observed in the controls. Pre- and post-treatment serum IL-6 levels were higher in chronic hepatitis patients and correlated with HAI score and HCV RNA prior to treatment. Diversely, this correlation was less significant after completion of the treatment. Furthermore, IL-6 concentrations depended on the type of response to treatment, i.e. they decreased in complete responders, while increased in partial and non-responders. Our data indicate that IL-6 concentrations, before treatment, are expression of viral-induced inflammation and that, after treatment, may be increased by the action of IFN-alpha treatment.

RESUMO

Interferon (IFN)-alpha is recognized today as the treatment of choice for chronic hepatitis virus C-related disease. Several factors are able to influence the response to the therapy. In the last few years, several types of IFN-alpha have been used with varying therapeutic results. In order to define the role played by the type of IFN-alpha, as a predictive factor of response to therapy, we studied clinical and biological features of 128 patients (80 males and 48 females, mean age 58.5+/-9.7 years) divided into four homogeneous groups. Four types of IFN-alpha were administered at the same dose and for an identical period. Lymphoblastoid was administered to Group A; recombinant 2a to Group B; recombinant 2b to Group C and leukocyte to Group D. The results showed that the best response was achieved using natural IFN. Statistical evaluation of the predictive factors was carried out using bivariate and multivariate analysis. IFN-alpha was associated with different response rates for viral and biochemical remission at the end of the treatment and at the end of 12 months' follow-up period. Therefore, the type of IFN administered may influence the response to therapy and important independent single predictive factors of response should be taken into account. The type of IFN used may determine how well the disease is controlled.

The role of comorbidity and the psycho-affective attitudes have been studied in 108 elderly oncological patients, in comparison with 25 elderly subjects without tumor pathologies. The results have revealed positive correlations between the activity of daily living (ADL), as well as the instrumental activity of daily living (IADL) scales and the comorbidity both in the oncological subjects and the controls. The performance status defined by the eastern cooperative oncology group (ECOG-PS) positively correlated with the parameters of ADL and IADL scales, demonstrating an increased vulnerability and fragility of the oncological patients in their everyday activities. An increased psychological fragility of the oncological patients has also been revealed by the scores of the geriatric depression scale (GDS), which might be cause and consequence at the same time of the disease itself. In addition, the polypathologies are not associated with an increased gravity of the tumor stage, although there have been 2.5 accompanying pathologies, mainly diseases of osteoarticular and cardial character. The correction of functional damages of various organs due to aging or concomitant or previous diseases is a period of fundamental importance for an adequate oncological therapy. The principal goal of any intervention in the elderly oncological patient should certainly be an improvement of the quality of life, including an alleviation of the impact of the diagnostic and therapeutic procedures on it.

RESUMO

The effects of aging on erythropoiesis and the factors regulating it are not well known. Erythropoietin (Epo) is a specific growth factor for the erythroid line and is mainly produced by the kidney. As data on the effects of aging on Epo are discordant we studied serum Epo concentrations in a group of apparently healthy subjects divided into age classes in order to evaluate age-related modifications and correlations with hemoglobin (Hb) and red blood cells (RBC). Our results revealed that Epo values were correlated with age. Epo was higher in the over 65 years age classes than observed in control subjects. We believe that the elevated Epo values in the latter age class may be required to maintain Hb and RBC within normal range.

RESUMO

Among the age-related problems, a progressive loss of self-sufficiency is an important issue. We conducted a detailed analysis on 400 ultraoctagenarians to detect the most frequent deficits and needs. Our study series consisted of 168 males and 232 females, grouped into age classes. This sample was collected over a 4 year period in old peoples' homes, private homes and hospitals. We utilized activity of daily living (ADL), instrumental activity of daily living (IADL) and mini mental state examination (MMSE) scales to evaluate self-sufficiency of the elderly people. Complete self-sufficiency was observed in a very small percentage of the sample, whereas most of the impairments was present in memory, in drug intake and diet. We conclude that social efforts must be aimed at creating a policy which recognizes the need for family care of ultraoctagenarians and grants incentives to achieve this goal.
