RESUMO

OBJECTIVES: The aim of the study was to assess zinc status of newborns with parenteral nutrition with or without a small bowel stoma, to determine the incidence of zinc deficit, and to determine the clinical factors associated with plasma zinc levels. METHODS: Monocentric cohort study including all liveborn infants receiving zinc parenteral intake at 500 µg ·â€Škg ·â€Šday and who benefited from at least 1 plasma zinc assessment during hospitalization. RESULTS: Sixty-eight dosages of zinc were performed in 50 newborns, divided into 3 groups (no stoma = 26, jejunostomy = 11, ileostomy = 13). Thirty-seven of the 50 infants were born preterm. The mean ± standard deviation plasma zinc was 14.9 ±â€Š4.3 µmol/L and was similar among the 3 groups. Sixty-four percent, 3%, and 34% of zinc values were within, below, and above the normal range, respectively. In infants with jejunostomy, only 1 plasma zinc value (5%) was below the reference range. Plasma zinc levels were negatively correlated with stoma output (r = -0.449; P = 0.013). In contrast to patients with limited intestinal losses (ie, no stoma and ileostomy groups) no association between zinc levels and postmenstrual age was observed in infants with a jejunostomy suggesting that 500 µg ·â€Škg ·â€Šday was adequate not only in preterm infants but also in term infants with a jejunostomy. CONCLUSION: Plasma zinc levels decrease significantly with the increase of stoma output volume of newborns with small bowel stoma. Zinc deficit was prevented in newborns with a small bowel stoma receiving of 500 µg ·â€Škg ·â€Šday of parenteral zinc.

RESUMO

BACKGROUND: The cost of anticancer drugs is constantly growing. The aim of this study was determine the impact in terms of cost reduction for anticancer drug in the Italian Health Service due to patient participation in clinical trials. METHODS: We evaluated the cost of drugs administered to patients treated in clinical trials at the National Cancer Institute of Naples in a four-week time period. Patients with a diagnosis of different cancers were considered, including adjuvant therapy and treatment for advanced disease, pharma sponsored and investigator initiated phase I, II and III clinical studies. We defined the expected standard treatment for each patient and we calculated the cost of the standard antineoplastic drugs that should be administered in clinical practice outside clinical trials. We used the market price of drugs to determine the cost savings value. Costs other than drugs were not included in the cost saving calculation. RESULTS: From 23.10.2017 to 17.11.2017, 126 patients were treated in 34 pharma sponsored and investigator initiated clinical trials, using experimental drugs provided free of charge by the sponsors, for an overall number of 152 cycles of therapy. If these patients were treated with conventional therapies in clinical practice the cost of antineoplastic drugs would account for 517,658 Euros, with an average of 5487 Euros saved per patients for a period of 4 weeks. CONCLUSIONS: Clinical trials with investigational antineoplastic drugs provided free of charge by Sponsors render considerable cost savings, with a tangible benefit in clinical and administrative strategies to reduce drug expenditures.

RESUMO

BACKGROUND: Recurrent/metastatic squamous cell carcinoma of the head and neck (SCCHN) has a poor prognosis and the combination of cisplatin and cetuximab, with or without 5-fluorouracil, is the gold standard treatment in this stage. Thus, the concomitant use of novel compounds represents a critical strategy to improve treatment results. Histone deacetylase inhibitors (HDACi) enhance the activity of several anticancer drugs including cisplatin and anti-Epidermal Growth Factor Receptor (anti-EGFR) compounds. Preclinical studies in models have shown that vorinostat is able to down regulate Epidermal Growth Factor Receptor (EGFR) expression and to revert epithelial to mesenchimal transition (EMT). Due to its histone deacetylase (HDAC) inhibiting activity and its safe use as a chronic therapy for epileptic disorders, valproic acid (VPA) has been considered a good candidate for anticancer therapy. A reasonable option may be to employ the combination of cisplatin, cetuximab and VPA in recurrent/metastatic SCCHN taking advantage of the possible positive interaction between histone deacetylase inhibitors, cisplatin and/or anti-EGFR. METHOD/DESIGN: V-CHANCE is a phase 2 clinical trial evaluating, in patients with recurrent/metastatic squamous cell carcinoma of the head and neck never treated with first-line chemotherapy, the concomitant standard administration of cisplatin (on day 1, every 3 weeks) and cetuximab (on day 1, weekly), in combination with oral VPA given daily from day -14 with a titration strategy in each patient (target serum level of 50-100 µg/ml). Primary end point is the objective response rate measured according to Response Evaluation Criteria in Solid Tumors (RECIST). Sample size, calculated according to Simon 2 stage minimax design will include 21 patients in the first stage with upper limit for rejection being 8 responses, and 39 patients in the second stage, with upper limit for rejection being 18 responses. Secondary endpoints are time to progression, duration of response, overall survival, safety. Objectives of the translational study are the evaluation on tumor samples of markers of treatment efficacy/resistance (i.e. γH2AX, p21/WAF, RAD51, XRCC1, EGFR, p-EGFR, Ki-67) and specific markers of VPA HDAC inhibitory activity (histones and proteins acetylation, Histone deacetylase isoforms) as well as valproate test, histones and proteins acetylation of peripheral blood mononuclear cell, tested on blood samples at baseline and at different time points during treatment. DISCUSSION: Overall, this study could provide a less toxic and more effective first-line chemotherapy regimen in patients with recurrent/metastatic squamous cell carcinoma of the head and neck by demonstrating the feasibility and efficacy of cisplatin/cetuximab plus valproic acid. Moreover, correlative studies could help to identify responder patients, and will add insights in the mechanism of the synergistic interaction between these agents.

RESUMO

OBJECTIVE: Overweight/obesity prevalence has increased dramatically worldwide. Recent evidence suggests sleep deprivation/fragmentation, fructose-exceedingly rich diets, and exposure to endocrine disruptors (eg, bisphenol A, BPA) as emerging additional factors involved in pathomechanisms and in the treatment resistance of obesity and its complications. Our study focuses on these factors for further preventive/therapeutic approaches in paediatric obesity. METHODS: Fifty-four Italian children (cases: n = 31 overweight/obese; controls: n = 23 normal weight) were clinically/anthropometrically characterised. Parents completed questionnaires on the relation between obesogenic factors and childhood obesity. BPA was measured by gas chromatography/tandem mass spectrometry on early morning urine samples. Correlations between the continuous variables were analysed using Spearman rank correlation. RESULTS: Sleep deprivation/fragmentation, nocturnal breathing problems, and daytime sleepiness increased with increasing body mass index, correlating with the presence of clinical markers of metabolic syndrome (eg, acanthosis nigricans). Frequency of sugar-enriched drink consumption and the amount of fructose per portion and/or per week increased, paralleling the ponderal excess and all the other anthropometric parameters. In the entire sample population, free and total BPA levels increased paralleling the body mass index increase (r > 0.8), whereas the conjugate demonstrated the opposite trend. The re-use of disposable plastic showed a positive correlation with urinary BPA levels. CONCLUSIONS: Despite its exploratory nature, the results of our pilot study confirm the close relation between certain factors and paediatric obesity, underscoring their role as emerging targets for prevention and therapy.

RESUMO

Salivary gland carcinomas (SGCs) are rare neoplasms, representing less than 10% of all head and neck tumors, but they are extremely heterogeneous from the histological point of view, their clinical behavior, and their genetics. The guidelines regarding their treatment include surgery in most cases, which can also play an important role in oligometastatic disease. Where surgery cannot be used, systemic therapy comes into play. Systemic therapy for many years has been represented by polychemotherapy, but recently, with the affirmation of translational research, it can also count on targeted therapy, at least in some subtypes of SGCs. Interestingly, in some SGC histotypes, predominant mutations have been identified, which in some cases behave as "driver mutations", namely mutations capable of governing the carcinogenesis process. Targeting these driver mutations may be an effective therapeutic strategy. Nonetheless, it is not always possible to have drugs suitable for targeting driver mutations-and targeting driver mutations is not always accompanied by a clinical benefit. In this review, we will analyze the main mutations predominant in the various histotypes of SGCs.

RESUMO

During a spontaneous and autonomous study, we assessed the ultrasound finding of lymphadenopathy after BNT162b2 Pfizer vaccine. We enrolled 18 patients with 58 lymphadenopathies: in 10 patients, they were in the laterocervical side, while in 8 patients in the axillar site. The largest diameter was 16 mm with a range from 7 to 16 mm (median value = 10 mm). In the same patient, we found different ultrasound nodal findings. A total of 25 nodes showed eccentric cortical thickening with wide echogenic hilum and oval shape. In total, 19 nodes showed asymmetric eccentric cortical thickening with wide echogenic hilum and oval shape. Overall, 10 nodes showed concentric cortical thickening with reduction in the width of the echogenic hilum and oval shape. A total of four nodes showed huge reduction and displacement of the echogenic hilum and round or oval shape. No anomaly was found at the Doppler echocolor study. In conclusion, eccentric cortical thickening with wide echogenic hilum and oval shape, asymmetric eccentric cortical thickening with wide echogenic hilum and oval shape, concentric cortical thickening with reduction in the width of the echogenic hilum and oval shape, and a huge reduction and displacement of the echogenic hilum and round shape are the features that we found in post BNT162b2 Covid-19 Vaccine lymphadenopathies.

RESUMO

BACKGROUND: The introduction of trastuzumab biosimilars in clinical practice plays an important role in promoting the sustainability of healthcare systems. By contrast, the switching process can be challenging to the clinics. This survey describes the switching process at a National Cancer Institute over a period of 2 years. METHODS: Data regarding all trastuzumab-based regimens for breast cancer (BC) from 1 January 2019 and 31 December 2020 were extracted from both adverse drug reactions (ADRs) reporting systems and electronic systems involved in inventory management, prescribing, dispensing, and administration. Both patients under monotherapy and combination treatment regimens were included. There were no exclusion criteria. RESULTS AND CONCLUSIONS: Overall 354 patients received at least one trastuzumab-based regimen for a total of 493 lines of treatment and 5769 administrations. Biosimilar were used in 34.3% of trastuzumab-based treatments. No differences between biosimilars and reference drug have been observed in terms of ADRs. The effective cost-saving of the first 2 years is greater than EUR 800,000 and it is estimated to increase over time.

RESUMO

AIM: The aim of the present study was to assess the estimated "per patient" total cost for a single Oncologic Italian Cancer Center participating in a multicenter clinical trial with new anticancer biological agents using the activity-based costing (ABC) methodology. METHODOLOGY: Nine randomized phase 3 clinical trials employing biological agents at the National Cancer Institute of Napoli, Italy, were analyzed to indentify "per patient" costs of each trial, according to the ABC methodology. The average consumption of resources for a patient completing the entire planned treatment was estimated for each trial. Through interviews of the personnel (doctors, nurses and technicians) and by analyses of the clinical trials protocols, the main activities of the 9 clinical trials were identified and, for each trial, the complete health care pathway of the patients and the treatment programmes were minutely reconstructed. Drug costs were not included because provided by Sponsors. PRINCIPAL FINDINGS: The average costs of the pre-study, treatment, monitoring, follow-up, audit, and administrative activities accounted for 2.357, 4.783, 700, 372, 1.263, and 9 Euro, respectively. The average total cost estimated for all "per patient" activities, including overhead costs, was 11.379 Euro. Staff costs accounted for € 5.988, while costs of diagnostic test accounted for 3.494 Euro. Clinical trials with immunotherapeutic drugs accounted for higher costs (+601 Euro as oncological staff costs, +1.318 Euro as intermediate services cost and +384 Euro as overheads). CONCLUSIONS: The average total cost estimated for all "per patient" activities of a clinical trial with new anticancer biological agents was 11.379 Euro using the ABC methodology.

RESUMO

Animal models of experimental liver carcinogenesis and epidemiological studies in humans suggest a relationship between sex hormones and hepatocellular carcinoma (HCC). In 1997, a systematic review of the existing, small randomized trials evaluating the antiestrogen tamoxifen yielded a positive result, but the large randomized CLIP-1 trial showed no survival advantage from the addition of tamoxifen to best supportive care. A possible explanation for the negative results is the lack of patient selection, but the expression of estrogen (ER) and progesterone (PgR) receptors in HCC does not clearly affect the survival outcome of the patients treated with tamoxifen. In the last years, it has been proposed that negative results might be due to the fact that tamoxifen in HCC could act via an ER-independent pathway, which requires much higher doses than those usually administered, but a double-blind Asian randomized trial conducted to assess possible dose-response effect showed no efficacy for tamoxifen, with an inversely negative impact with increasing dose. According to the results of large trials and of the Cochrane systematic review, neither further trials are warranted with tamoxifen in HCC, nor should any use in clinical practice be considered. Interesting results have been obtained when the type of hormonal treatment (tamoxifen or megestrol) has been chosen according to the presence of wild-type or variant ER, but these results should be confirmed in large randomized trials. Negative results have been obtained with antiandrogen therapy. In conclusion, hormonal treatment should not be a part of the current management of HCC patients.

RESUMO

BACKGROUND AND AIMS: Several neuromotor disorders share exclusive, although often overlooked, nutritional problems. The objective of this study is therefore to delineate the frequency of malnutrition, evaluate the effectiveness of nutritional care, and identify issues needing to be possibly strengthened when caring for these patients into a general pediatrics department. PATIENTS AND METHODS: The study included 30 patients, 21 males and 9 females, aged between 2 and 15 years, affected by cerebral palsy, epileptic encephalopathy, and severe psychomotor developmental delay.Nutritional status was assessed by a dietary questionnaire administered to parents to investigate feeding difficulties; 3 days food diary to quantify daily calorie intake; anthropometrical (weight, height/length, body mass index percentiles, plicometry, specific body segments measurement) and blood (blood count, serum iron, albumin, transferrin, calcium, phosphorus) parameters. RESULTS: More than 44% individuals of the study population was at risk of malnutrition, according to feeding difficulties, progressive depletion of weight, reduced daily calorie intake, reduced albumin and transferrin levels. This occurred despite a massive caregivers commitment, as documented by almost universal parental constant assistance during their long-duration meals. CONCLUSIONS: Our results individuate the nutritional aspect being still a problem in the care of children with severe neuromotor disability.

RESUMO

The epidemics of overweight and obesity has resulted in a significant increase of non alcoholic fatty liver disease (NAFLD), a potentially progressive condition. Currently, obesity related hepatopathy represents therefore the main cause of pediatric chronic liver disease. The first choice treatment at all ages is weight loss and/or lifestyle changes, however compliance is very poor and a pharmacological approach has become necessary. In the present article we present a systematic literature review focusing on established pediatric NALFD drugs (ursodeoxycholic acid, insulin sensitizers, and antioxidants) and on innovative therapeutic options as well.Regarding the former ones, a pediatric pilot study highlighted that ursodeoxycholic acid is not efficient on transaminases levels and bright liver. Similarly, a recent large scale, multicenter randomized clinical trial (TONIC study) showed that also insulin sensitizers and antioxidant vitamin E have scarce effects on serum transaminase levels. Among a large series of novel therapeutic approaches acting on recently proposed different pathomechanisms, probiotics seem hitherto the most interesting and reasonable option for their safety and tolerability. Toll-like receptors modifiers, Pentoxifylline, and Farnesoid X receptors agonists have been still poorly investigated, and will need further studies before becoming possible promising innovative therapeutic strategies.

RESUMO

PURPOSE: The present study was aimed at defining the antitumor activity of the cisplatin-epirubicin-paclitaxel (PET) weekly administration with granulocyte colony-stimulating factor (G-CSF) support in chemonaive small-cell lung cancer patients with extensive disease (ED-SCLC). METHODS: Chemonaive ED-SCLC patients received cisplatin 30 mg/sqm, epirubicin 50 mg/sqm and paclitaxel 120 mg/sqm, weekly, with G-CSF (5 microg/kg from day 3 to 5) support, for a maximum of 12 weeks. RESULTS: Thirty-nine patients were treated, for a total of 354 cycles delivered. Eight complete (21%), and 22 partial responses (56%) were recorded, giving a 77% (95% CI = 61-89%) objective response rate (ORR). After 14 (range, 7-28)-month median follow-up, 24 deaths have occurred. Median progression-free and overall survival were 7 months and 11 months, with 1- and 2-year projected survivals of 45 and 24%, respectively. No toxic deaths occurred. Grade 4 neutropenia and thrombocytopenia occurred in 4 (10%) and 1 (3%) patients, respectively. Only one case of neutropenic sepsis was recorded, while hemorrhagic thrombocytopenia was never observed. Emesis, loss of appetite, mucositis and fatigue were the main nonhematological toxicities, being severe in 9, 8, 4 and 7 patients, respectively. CONCLUSIONS: The weekly PET combination with G-CSF support represents an active therapeutic approach in chemonaive ED-SCLC patients. However, both ORR and median survival does not seem substantially better than those achievable with a standard regimen. In view of that, and in consideration of the relevant nonhematological toxicity, this approach should not be pursued outside clinical trials.

RESUMO

PURPOSE: To evaluate the feasibility and activity of combination treatment with docetaxel (DTX) and irinotecan (CPT-11), given together every other week, combined with filgrastim support, in anthracycline- and paclitaxel-pretreated breast cancer (BC) patients. PATIENTS AND METHODS: Advanced BC patients pretreated with anthracycline- and paclitaxel-based chemotherapy were eligible. DTX (80 mg/m2) and CPT-11 (100 mg/m2) were given biweekly with filgrastim support (300 microg/day on days 4-7). RESULTS: Fifty patients (48 with metastatic and 2 with locally advanced cancer) were enrolled, with a total of 318 cycles being delivered. Thirty-one patients had visceral localizations. All patients had received epirubicin plus paclitaxel, with or without cisplatin, as front-line treatment for advanced disease. Overall, fatigue and diarrhea were the main chemotherapy-related toxicities in this study, being severe in 10 (20%) and 4 (8%) patients. Grade 3 or 4 neutropenia and thrombocytopenia occurred in 18 (36%) and 6 (12%) patients, respectively. Red blood cell transfusions were required in 4 patients. A total of 32 objective responses were registered (overall response rate, ORR = 64%, 95% confidence interval = 49-77%), including 8 complete responses (16%). An additional 8 patients showed stable disease. After a median follow-up of 18 (range 4-29) months, 30 patients were still alive, and 19 were progression free; median progression-free and overall survivals were 10 and 23 months, respectively. CONCLUSIONS: Biweekly DTX/CPT-11 with G-CSF support is a well-tolerated and highly effective approach in anthracycline-/paclitaxel-pretreated patients. The very promising ORR and survival outcome observed in this subset of patients with a poor prognosis suggest that this regimen might play a major role in the management of this disease.
