Overall survival with 3 or 6 months of adjuvant chemotherapy in Italian TOSCA phase 3 randomised trial.

BACKGROUND: Oxaliplatin-based adjuvant chemotherapy is the standard treatment of high-risk colon cancer (CC). A shorter duration (3 months) can achieve a similar outcome [in terms of relapse-free survival (RFS)] to a longer duration. This study reports the overall survival (OS) analysis of the three or six colon adjuvant (TOSCA) phase III study. It assessed different adjuvant chemotherapy durations in patients with resected high-risk stage II and stage III CC. MATERIAL AND METHODS: TOSCA was an open-label, phase III, multicentre, non-inferiority trial conducted in 130 Italian centres. Patients were randomly assigned, in a 1 : 1 ratio, to receive 3 months of standard doses of FOLFOX/CAPOX, or 6 months of FOLFOX/CAPOX. Patients with histologically confirmed high-risk stage II and III CC were included, with RFS being the primary end point. OS was a secondary end point. RESULTS: From June 2007 to March 2013, 3759 patients were accrued. At a median follow-up of 7 years, the hazard ratio (HR) for RFS of the 3-month versus 6-month arms was 1.13; 95% confidence interval (CI) 0.99-1.29, P for non-inferiority = 0.380, P for superiority = 0.068, crossing the non-inferiority limit of 1.20. This result did not allow us to reject the null hypothesis of the inferiority of the 3-month arm. The HR for OS of the 3-month versus 6-month arms was 1.09 (95% CI 0.93-1.26, P for superiority = 0.288). At the last follow-up analysis, the absolute OS difference between arms was <1%. CONCLUSIONS: The present analysis of the TOSCA trial does not indicate any significant difference in OS between the treatment groups. The extra benefit provided by the longer treatment should be balanced against the extra toxicity of more prolonged therapy. The trial is registered with ClinicalTrials.gov, registration number: NCT0064660.

Mercury in the Black Sea: New Insights From Measurements and Numerical Modeling.

Redox conditions and organic matter control marine methylmercury (MeHg) production. The Black Sea is the world's largest and deepest anoxic basin and is thus ideal to study Hg species along the extended redox gradient. Here we present new dissolved Hg and MeHg data from the 2013 GEOTRACES MEDBlack cruise (GN04_leg2) that we integrated into a numerical 1-D model, to track the fate and dynamics of Hg and MeHg. Contrary to a previous study, our new data show highest MeHg concentrations in the permanently anoxic waters. Observed MeHg/Hg percentage (range 9-57%) in the anoxic waters is comparable to other subsurface maxima in oxic open-ocean waters. With the modeling we tested for various Hg methylation and demethylation scenarios along the redox gradient. The results show that Hg methylation must occur in the anoxic waters. The model was then used to simulate the time evolution (1850-2050) of Hg species in the Black Sea. Our findings quantify (1) inputs and outputs of HgT (~31 and ~28 kmol yr-1) and MeHgT (~5 and ~4 kmol yr-1) to the basin, (2) the extent of net demethylation occurring in oxic (~1 kmol yr-1) and suboxic water (~6 kmol yr-1), (3) and the net Hg methylation in the anoxic waters of the Black Sea (~11 kmol yr-1). The model was also used to estimate the amount of anthropogenic Hg (85-93%) in the Black Sea.

A phase III trial comparing oral S-1/cisplatin and intravenous 5-fluorouracil/cisplatin in patients with untreated diffuse gastric cancer.

BACKGROUND: The effect of histology-based treatment regimen on diffuse gastric adenocarcinoma has not been evaluated in clinical trials. This international phase III trial evaluated the efficacy and safety of S-1 (a contemporary oral fluoropyrimidine)/cisplatin versus 5-fluorouracil (5-FU)/cisplatin in chemotherapy-naïve patients with diffuse-type adenocarcinoma involving the gastroesophageal junction or stomach. PATIENTS AND METHODS: Eligibility criteria included untreated, measurable, advanced diffuse adenocarcinoma confirmed by central pathology and performance status of 0-1. Patients were randomized (2 : 1) to receive S-1/cisplatin or 5-FU/cisplatin. Primary end point was overall survival (OS), and secondary end points were progression-free survival, time to treatment failure, overall response rate, and safety. A multivariable analysis was also carried out. RESULTS: Overall, 361 patients were randomized (S-1/cisplatin, n = 239; 5-FU/cisplatin, n = 122); half (51%) were men, and median age was 56.0 years. In each group, median number of treatment cycles per patient was 4 (range, S-1/cisplatin: 1-20; 5-FU/cisplatin: 1-30), and dose intensity was >95%. OS was not different in the two groups {median OS with S-1/cisplatin, 7.5 [95% confidence interval (CI): 6.7, 9.3]; 5-FU/cisplatin, 6.6 [95% CI: 5.7, 8.1] months; hazard ratio, 0.99 [95% CI: 0.76, 1.28]; P = 0.9312}. Overall response rate was significantly higher in the S-1/cisplatin than 5-FU/cisplatin group (34.7% versus 19.8%; P = 0.01), but progression-free survival and time to treatment failure were not different. Safety was similar between the 2 groups; however, fewer patients treated with S-1/cisplatin than 5-FU/cisplatin had ≥1 grade 3/4 treatment-emergent adverse event or ≥1 adverse event resulting in treatment discontinuation. One treatment-related death occurred in each group. Slow accrual led to early termination. CONCLUSIONS: These data suggest that S-1/cisplatin and 5-FU/cisplatin are similar in efficacy and safety in untreated patients with advanced diffuse adenocarcinoma of the gastroesophageal junction or stomach. The primary end point was not met. CLINICALTRIAL.GOV REGISTRATION NUMBER: NCT01285557.

A randomized trial of intensive versus minimal surveillance of patients with resected Dukes B2-C colorectal carcinoma.

BACKGROUND: Colorectal cancer is the third most common and the third most lethal cancer in both men and women in developed countries. About 75% of cases are first diagnosed when the disease is classified as localized or regional, undergo potentially curative treatment and enter a post-treatment surveillance program. Although such programs drain significant resources from health systems, empirical evidence of their efficacy is scanty. PATIENTS AND METHODS: Dukes B2-C colorectal cancer patients who had no evidence of disease at the end of their front-line treatment (surgery and adjuvant radiochemotherapy, if indicated) were eligible for the trial and randomized to two different surveillance programs. These programs differed greatly in the frequency of diagnostic imaging. They had similar schedules of physical examinations and carcinoembryonic antigen (CEA) assessments. Patients received baseline and yearly health-related quality-of-life (HR-QoL) questionnaires. Primary outcomes were overall survival (OS) and QoL. RESULTS: From 1998 to 2006, 1228 assessable patients were randomized, 933 with colon cancer and 295 with rectal cancer. More than 90% of patients had the expected number of diagnostic procedures. Median follow-up duration was 62 months [interquartile range (IQR) 51-86] in the minimal surveillance group and 62 months (IQR 50-85) in the intensive group. At primary analysis, 250 patients had recurred and 218 had died. Intensive surveillance anticipated recurrence, as shown by a significant difference in mean disease-free survival of 5.9 months. Comparison of OS curves of the whole intention-to-treat population showed no statistically significant differences. HR-QoL of life scores did not differ between regimens. CONCLUSION: Our findings support the conclusions of other randomized clinical trials, which show that early diagnosis of cancer recurrence is not associated with OS benefit.

Phase III trial comparing 3-6 months of adjuvant FOLFOX4/XELOX in stage II-III colon cancer: safety and compliance in the TOSCA trial.

BACKGROUND: Six months of oxaliplatin-based adjuvant chemotherapy is standard of care for radically resected stage III colon cancer and an accepted option for high-risk stage II. A shorter duration of therapy, if equally efficacious, would be advantageous for patients and Health-Care Systems. PATIENTS AND METHODS: TOSCA ['Randomized trial investigating the role of FOLFOX-4 or XELOX (3 versus 6 months) regimen duration and bevacizumab as adjuvant therapy for patients with stage II/III colon cancer] is an open-label, phase III, multicenter, noninferiority trial randomizing patients with high-risk stage II or stage III radically resected colon cancer to receive 3 months (arm 3 m) versus 6 months (arm 6 m) of FOLFOX4/XELOX. Primary end-point was relapse-free survival. We present here safety and compliance data. RESULTS: From June 2007 to March 2013, 3759 patients were accrued from 130 Italian sites, 64% receiving FOLFOX4 and 36% XELOX in either arm. Treatment completion rate without any modification was 35% versus 12% and with delays or dose reduction 52% versus 44% in arm 3 and 6 m. Treatment was permanently discontinued in 8% (arm 3 m) and 33% (arm 6 m). In arm 6 m, 50% of patients discontinuing treatment did so after completing 80% of planned program. Grade 3+ toxicities were higher in arm 6 m than that in 3 m. Grade 2+ neuropathy was 31.2% versus 8.8% (P < 0.0001) while grade 3+ was 8.4 versus 1.3 (P < 0.0001), in arm 3 and 6 m. Seven deaths within 30 days from last treatment administration in arm 6 m and three deaths in arm 3 m were observed (0.3% versus 0.1%, P = 0.34). CONCLUSIONS: TOSCA is the first trial comparing 3 versus 6 months of adjuvant chemotherapy completing accrual within the international initiative of treatment duration evaluation (International Duration Evaluation of Adjuvant, IDEA). High compliance to treatment in control arm will allow a correct assessment of potential differences between the two treatment durations. CLINICALTRIALSGOV REGISTRATION NUMBER: NCT00646607.

Randomized trial on adjuvant treatment with FOLFIRI followed by docetaxel and cisplatin versus 5-fluorouracil and folinic acid for radically resected gastric cancer.

BACKGROUND: Some trial have demonstrated a benefit of adjuvant fluoropirimidine with or without platinum compounds compared with surgery alone. ITACA-S study was designed to evaluate whether a sequential treatment of FOLFIRI [irinotecan plus 5-fluorouracil/folinic acid (5-FU/LV)] followed by docetaxel plus cisplatin improves disease-free survival in comparison with 5-FU/LV in patients with radically resected gastric cancer. PATIENTS AND METHODS: Patients with resectable adenocarcinoma of the stomach or gastroesophageal junction were randomly assigned to either FOLFIRI (irinotecan 180 mg/m(2) day 1, LV 100 mg/m(2) as 2 h infusion and 5-FU 400 mg/m(2) as bolus, days 1 and 2 followed by 600 mg/m(2)/day as 22 h continuous infusion, q14 for four cycles) followed by docetaxel 75 mg/m(2) day 1, cisplatin 75 mg/m(2) day 1, q21 for three cycles (sequential arm) or De Gramont regimen (5-FU/LV arm). RESULTS: From February 2005 to August 2009, 1106 patients were enrolled, and 1100 included in the analysis: 562 in the sequential arm and 538 in the 5-FU/LV arm. With a median follow-up of 57.4 months, 581 patients recurred or died (297 sequential arm and 284 5-FU/LV arm), and 483 died (243 and 240, respectively). No statistically significant difference was detected for both disease-free [hazard ratio (HR) 1.00; 95% confidence interval (CI): 0.85-1.17; P = 0.974] and overall survival (OS) (HR 0.98; 95% CI: 0.82-1.18; P = 0.865). Five-year disease-free and OS rates were 44.6% and 44.6%, 51.0% and 50.6% in the sequential and 5-FU/LV arm, respectively. CONCLUSIONS: A more intensive regimen failed to show any benefit in disease-free and OS versus monotherapy. CLINICAL TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT01640782.

[A full economic evaluation of extensive vaccination against rotavirus with RIX4414 vaccine at National and Regional level in Italy]. / Una valutazione economica completa della vaccinazione estensiva contro i rotavirus con il vaccino RIX4414 a livello nazione e regionale in Italia.

Vaccination of all healthy children against rotavirus (RV) has been recommended, since the availability of vaccines, both in Europe (PIDJ) and Italy (pediatricians). The aims of universal vaccination against RV include the protection of children against moderate/severe gastroenteritis forms by RV (GARV), prevent hospitalizations, reduce the severity and duration of the disease, and reduce morbidity and socioeconomic costs. Payers need to informed regarding the efficacy and the healthcare utilization related to RV vaccination in order to decide in favour of its extensive implementation. The aim of this paper is to assess the clinical and financial impact of the extensive vaccination aganist RV both at National and Regional level. Particular attention, compared to the previous analysis (Standaert et al, 2008) has been given to the influence of herd immunity (HI) on cost-utility results of vaccination against-RV. Methods. The analysis was conducted with the Markovian model previously used by Standaert B et al and updated for comparing costs and benefits associated with a situation of vaccination anti-RV that includes efficacy data due to HI, with a situation without vaccination. For the base case is assumed an annual coverage of 90%, where the effect of HI is present in the population at risk (0-5 years) and extended to children who have not been vaccinated, adding as conservative assumption, a further 10% to the efficacy of the vaccine, compared to 15% determined by several published studies. Two analysis have been made based on this model: a cost-utility analysis that compared vaccination with two doses of RIX441410 administered at 2 and 3 months after birth compared with no vaccination from National Health Service and Society perspective; a budget impact analysis at National and Regional level. The evaluation has as its main element the reduction of cases of infection through universal vaccination and consequent reduction of Garv events and nosocomial infections. Results. From the NHS perspective, in a cohort of 555,791 born in Italy in 2011, the annual number of hospitalizations due to RV infections in the absence of vaccination is estimated to be 14,550 units. Assuming that 90% of newborns receive two doses of the vaccine, and including an additional effect of HI to the efficacy of the vaccine, vaccination would lead to a reduction of 71% of cases of Garv (176,804 cases in less) and a 86% of hospitalizations due to Garv (12,913 fewer cases), with an impact on quality of life and mortality as a consequence of vaccination. The introduction of the vaccine would lead to a gain of 0.0014 QALYs and 0.0022 life-years gained per child compared to a situation without vaccination (assuming a discount rate of 3% on future benefits). The reduction of GARV also would lead to a strong economic impact. The introduction of the vaccine would lead to a saving of € 25.41 per child or a saving of more than € 14 million for the whole population included in the analysis. Cost reduction increase significantly from the perspective of society and introducing the indirect costs due to lost productivity. In this case, the savings due to the introduction of vaccination would increase to € 67,747,654 in the total cohort, or € 121.89 per child. In an alternative scenario, where HI is excluded, RIX4414 remains dominant (0.0013 QALYs gained and € 22.14 per child saved). The budget impact analysis shows that, as early as the second year, the additional cost of the vaccine is more than offset by a reduction in costs of the disease, which leads to savings for the NHS, which increases from year 3. In a time horizon of 5 years (without the discount rate), the savings for the NHS amount to € 34,440,314. These savings would amount to a cost reduction of € 4.64 per child over 5 years (€ 0.93 per year). The savings due to the introduction of the vaccine were mainly due to a reduction in costs associated with hospitalizations. The budget impact analysis at regional level, has taken a vaccine cost of € 30.00 per dose. Cases of diarrhoea before after vaccination are reduced in each region, based on the number of births, ranging from a minimum of 399 cases avoided for Valle d'Aosta to a maximum of 31,116 cases avoided in Lombardy. In a similar way, the number of hospitalizations due to GARV are reduced considerably, from a minimum of 36 cases in Valle d'Aosta to a maximum of 3,096 in Lombardy. Obviously, these reductions are greater in regions with 30,000 or more births per year. Conclusions. This study suggests that a universal vaccination anti-RV with 2 doses of RIX4414 brings significant clinical and economic benefits both at National and Regional level. The indirect effects of the vaccine (HI) could generate protection even in unvaccinated children with health gain and a number of cases by GARV much less than those that would vaccinating small groups of children and with a cost of illness, for NHS, which would be reduced significantly, despite the additional costs of the vaccine as early as the second year of vaccination. Productivity losses due to absence from work of a parent, as well as all other costs included in the model, show that is precisely the society to pay the consequences, from economic and social point of view. Considering the citizen in the role of private payer, we must stress as for him, the savings generated by vaccination, whether universal or with demand for cost-sharing by the health service, prove significant with a major health gain for the population under study.

Regorafenib monotherapy as second-line treatment of patients with RAS-mutant advanced colorectal cancer (STREAM): an academic, multicenter, single-arm, two-stage, phase II study.

BACKGROUND: Maintaining angiogenesis inhibition and switching the chemotherapy backbone represent the current second-line therapy in patients with RAS-mutant metastatic colorectal cancer (mCRC). Regorafenib, an oral multikinase inhibitor, prolonged overall survival (OS) in the chemorefractory setting. MATERIALS AND METHODS: STREAM was an academic, multicenter, single-arm phase II trial, evaluating the activity of regorafenib in RAS-mutant mCRC, in terms of the rate of patients who were progression-free after 6 months from study entry (6mo-PF). Patients were pretreated with fluoropyrimidine, oxaliplatin, and bevacizumab. According to Simon's two-stage design, ≥18 patients 6mo-PF were needed in the overall population (N = 46). Secondary endpoints were safety, objective response rate (ORR), progression-free survival (PFS), and OS. Early metabolic response by [18F]2-fluoro-2-deoxy-D-glucose-positron emission tomography/computed tomography ([18F]-FDG PET/CT) scan was an exploratory endpoint. EudraCT Number: 2015-001105-13. RESULTS: The number of patients 6mo-PF was 8/22 at the first stage and 14/46 in the overall population. The ORR was 10.9%, disease control rate was 54.6%, median (m)PFS was 3.6 months [95% confidence interval (CI) 1.9-6.7 months], mOS was 18.9 months (95% CI 10.3-35.3 months), and mPFS2 (from study entry to subsequent-line progression) was 13.3 months (95% CI 8.4-19.7 months). Long benefiter patients (>6mo-PF) significantly more often had a single metastatic site and lung-limited disease. No unexpected toxicity was reported. Grade ≥3 events occurred in 39.1% of patients, with hand-foot syndrome (13%), fatigue, and hyperbilirubinemia (6.5%) occurring mostly. Baseline metabolic assessment was associated with OS in the multivariate analysis, while early metabolic response was not associated with clinical outcomes. CONCLUSIONS: The study did not meet its primary endpoint. However, regorafenib was well tolerated and did not preclude subsequent treatments. Patients with good prognostic features (single metastatic site and lung-limited disease) reported clinical benefit with regorafenib. The exploratory metabolic analysis suggests that baseline [18F]-FDG PET/CT might be useful to select patients with a favorable outcome. A chemotherapy-free interval with regorafenib was associated with durable disease control in a selected group of patients with favorable clinical characteristics.

A multicentre study on spontaneous in-cage activity and micro-environmental conditions of IVC housed C57BL/6J mice during consecutive cycles of bi-weekly cage-change.

Mice respond to a cage change (CC) with altered activity, disrupted sleep and increased anxiety. A bi-weekly cage change is, therefore, preferred over a shorter CC interval and is currently the prevailing routine for Individually ventilated cages (IVCs). However, the build-up of ammonia (NH3) during this period is a potential threat to the animal health and the literature holds conflicting reports leaving this issue unresolved. We have therefor examined longitudinally in-cage activity, animal health and the build-up of ammonia across the cage floor with female and male C57BL/6 mice housed four per IVC changed every other week. We used a multicentre design with a standardised husbandry enabling us to tease-out features that replicated across sites from those that were site-specific. CC induce a marked increase in activity, especially during daytime (~50%) when the animals rest. A reduction in density from four to two mice did not alter this response. This burst was followed by a gradual decrease till the next cage change. Female but not male mice preferred to have the latrine in the front of the cage. Male mice allocate more of the activity to the latrine free part of the cage floor already the day after a CC. A behaviour that progressed through the CC cycle but was not impacted by the type of bedding used. Reducing housing density to two mice abolished this behaviour. Female mice used the entire cage floor the first week while during the second week activity in the latrine area decreased. Measurement of NH3 ppm across the cage floor revealed x3 higher values for the latrine area compared with the opposite area. NH3 ppm increases from 0-1 ppm to reach ≤25 ppm in the latrine free area and 50-100 ppm in the latrine area at the end of a cycle. As expected in-cage bacterial load covaried with in-cage NH3 ppm. Histopathological analysis revealed no changes to the upper airways covarying with recorded NH3 ppm or bacterial load. We conclude that housing of four (or equivalent biomass) C57BL/6J mice for 10 weeks under the described conditions does not cause any overt discomfort to the animals.

Phase II study of panitumumab, oxaliplatin, 5-fluorouracil, and concurrent radiotherapy as preoperative treatment in high-risk locally advanced rectal cancer patients (StarPan/STAR-02 Study).

BACKGROUND: The aim of this phase II study was to assess the activity of panitumumab in combination with oxaliplatin, 5-fluorouracil, and external radiotherapy (RT) as preoperative treatment in locally advanced rectal cancer patients. PATIENTS AND METHODS: Patients had rectal adenocarcinoma, cT3N+ or cT4N-/+ stage, located <12 cm from the anal margin. Panitumumab was administered before the start of chemo-RT, and every 2 weeks in combination with 5-fluorouracil-oxaliplatin with concurrent RT. Rectal surgery was carried out 7-8 weeks after the end of neoadjuvant treatment. The primary end point was a pathological complete response rate of 25%. RESULTS: Sixty patients were enrolled from February 2007 to October 2009. Fifty-five (91.7%) patients underwent surgery. Rate of pathological complete response was 21.1% (95% confidence interval 10.4% to 31.6%). Pathological downstaging occurred in 33 of 57 (57.9%) patients. Grade 3-4 toxicity during neoadjuvant treatment was diarrhea (38.9%), cutaneous reactions (18.6%), nausea (5.1%), asthenia (3.4%), anorexia (3.4%), and neutropenia (1.7%). One toxic death was observed for diarrhea. CONCLUSIONS: In our study, the primary end point is not reached and panitumumab combination treatment was associated with high incidence of grade 3-4 diarrhea. The higher pathological complete response rate in comparison with the results of previous neoadjuvant rectal cancer trials with anti-epidermal growth factor receptor monoclonal antibodies supports further studies necessary to understand the possibility of optimal regimens and sequences with chemo-RT.

Gene expression profile of human colon cancer cells treated with cross-reacting material 197, a diphtheria toxin non-toxic mutant.

Cross-Reacting Material 197 (CRM197) is a diphtheria toxin non-toxic mutant that has shown antitumor activity in mice and humans. It is still unclear whether this anti-tumorigenic effect depends on its strong inflammatory-immunological property, its ability to inhibit heparin-binding epidermal growth factor (HB-EGF), or even its possible weak toxicity. CRM197 is utilized as a specific inhibitor of HB-EGF that competes for the epidermal growth factor receptor (EGFR), overexpressed in colorectal cancer and implicated in its progression. In this study we evaluate the effects of CRM197 on HT-29 human colon cancer cell line behaviour and, for CRM197 recognized ability to inhibit HB-EGF, its possible influence on EGFR activation. In particular, while HT-29 does not show any reduction of viability after CRM197 treatment (MTT modified assay), or changes in cell cycle distribution (flow cytometry), in EGFR localization, phospho-EGFR detected signals (immunohistochemistry) or in morphology (scanning electron microscopy, SEM) they show a change in the gene expression profile by microarray analysis (cDNA microarray SS-H19k8). The overexpression of genes like protein phosphatase 2, catalytic subunit, alpha isozyme (PPP2CA), guanine nucleotide-binding protein G subunit alpha-1(GNAI1) and butyrophilin, subfamily 2, member A1 (BTN2A1) has been confirmed with real-time-qPCR. This is the first study where the CRM197 treatment on HT-29 shows a possible scarce implication of endogenous HB-EGF on EGFR expression and cancer cell development. At the same time, our results show the alteration of a specific and selected number of genes.

Optimizing clinical care in patients with advanced soft tissue sarcoma: a phase II study of a new schedule of high-dose continuous infusion ifosfamide and doxorubicin combination.

BACKGROUND: Ifosfamide and doxorubicin combination is an active regimen for patients with advanced soft tissue sarcomas (STS) but is burdened by high toxicity. A phase II trial was designed to assess the activity of continuous infusion ifosfamide and doxorubicin combination. PATIENTS AND METHODS: Thirty-four chemotherapy-naive patients with advanced STS were treated with ifosfamide (13 g/m(2)/12 days as continuous infusion) and doxorubicin (75 mg/m(2) on day 8) every 28 days with granulocyte colony-stimulating factor. RESULTS: The major toxicity was hematological: grade 3/4 neutropenia, anemia and thrombocytopenia occurred in 63, 30 and 12% of patients, respectively. The disease control rate was 68% and the median time to progression was 7.1 months. Among leiomyosarcomas, 2 partial responses and 4 stable diseases were observed. CONCLUSIONS: Our study confirms that the ifosfamide and doxorubicin combination has a very low non-hematological toxicity profile. This regimen attained a high disease control rate with moderate activity. Further investigation into leiomyosarcoma is warranted.

NEPA (netupitant/palonosetron) for the antiemetic prophylaxis of nausea and vomiting induced by chemotherapy (CINV) with Folfirinox and Folfoxiri even during the COVID-19 pandemic: a real-life study.

OBJECTIVE: The outbreak of coronavirus disease 2019 (COVID-19) has affected the treatment of cancer patients, with particular regard to the management of both chemotherapy and side effects. Chemotherapy-induced nausea and vomiting (CINV) are amongst the most troublesome side effects that impair patients' adherence to treatments and their quality of life (QoL). NEPA (Akynzeo®), is an oral fixed-dose combination of netupitant [a neurokinin-1 receptor antagonist (NK1RA), 300 mg] and palonosetron [(5-hydroxytryptamine (serotonin or 5HT) type3 receptor antagonist (5HT3RA), 0.5 mg] which has been shown to be effective in preventing CINV. PATIENTS AND METHODS: This prospective study started before the outbreak of COVID-19 and was carried out during the pandemic period. The aim was to evaluate the efficacy and safety of a single oral dose NEPA plus 12 mg of dexamethasone (DEX) in patients treated with Folfoxiri plus Bevacizumab and Folfirinox. The patients were diagnosed with advanced colorectal cancer (CRC) or advanced pancreatic ductal adenocarcinoma (PDAC). They were divided into two groups: naïve patients and patients previously treated with serotonin receptor antagonists (5HT3-RA) and neurokin-1 receptor antagonists (NK1-RA). RESULTS: During the overall phase, the complete response (CR) rate was 96.8% in naïve patients treated with Folfoxiri plus Bevacizumab, and 94.6% in patients treated with Folfirinox. During the acute and delayed phases, the CR rate was 92.8% and 94.2%, with Folfoxiri and Bevacizumab, as well as 96.2% and 94.6%, with Folfirinox. There was no adequate control of CINV events in patients on antiemetic prophylaxis with 5HT3-RA or NK1-RA associated with cortisone. During the overall phase, the CR rate was 74.6% with Folfoxiri plus Bevacizumab and 75.8% with Folfirinox. During the acute and delayed phases, the CR rate was 72.5% and 74.8% with Folfoxiri plus Bevacizumab, as well as 75.2% and 74.6% with Folfirinox. CONCLUSIONS: This study has shown the therapeutic benefits of NEPA in the management and prophylaxis of CINV events, both in naive patients and patients previously treated with 5HT3-RA and NK1-RA. In addition, NEPA has been shown to be safe, both before and during the COVID-19 pandemic.

The recommended lifetime immunization schedule from the board of vaccination calendar for life in Italy: A continuing example of impact on public health policies.

The Vaccination Calendar for Life is an alliance of scientific and professional societies of public health physicians, paediatricians and general practitioners in Italy which provides a periodical update on the ideal, scientifically driven vaccination calendar throughout lifetime. Since 2012, the Lifetime Immunization Schedule has represented a benchmark for Regional and National Authorities to set up the updated list of vaccines provided actively and free of charge to infants, children, adolescents, adults and the elderly by inclusion in the Triennial National Vaccination Plan (TNVP), and in the Essential Levels of Care (LEA). The impact of the different editions of the Lifetime Immunization Schedule on the TNVP was deep, representing the inspiring source for the present vaccination policy. The 2019 edition called for more attention to pregnant women immunization; risk groups vaccination; uniform high coverage with the MMRV vaccine; extension of Meningococcal B vaccination also at adolescent age; use of quadrivalent conjugate meningococcal vaccine also at 1 year of life; progressive decrease of the age of free-of-charge offer of influenza to ≥ 60 and then to ≥ 50 year-old population; implementation of flu immunization ages 6 months-6 years; HPV vaccination also offered to 25-year old women at the time of the first screening (gender neutral immunization already offered); sequential PCV13-PPV23 pneumococcal vaccination in 65 year-old subjects; increased coverage with rotavirus vaccine in infants and zoster vaccine in the elderly.

Maintain and increase vaccination coverage in children, adolescents, adults and elderly people: Let's avoid adding epidemics to the pandemic: Appeal from the Board of the Vaccination Calendar for Life in Italy: Maintain and increase coverage also by re-organizing vaccination services and reassuring the population.

The Board of the Vaccination Calendar for Life (Bonanni et al., 2014, 2017) [1,2]), a coalition of four major scientific and professional societies of public health physicians, pediatricians and general practitioners in Italy, made an appeal to health authorities in order to sustain vaccination in COVID-19 times. The five pillars to maintain and increase vaccination coverage at all ages are described as follows: 1) Guarantee paediatric vaccination coverage to all newborns and paediatric boosters and adolescent immunizations, not interrupting active calls and scheduled sessions. 2) Re-organise the way paediatric and adolescent vaccinations are offered. 3) Set-up recovery programs for vaccinations not carried out after the start of the COVID-19 emergency. 4) Provide the preparation of tenders for the supply of flu vaccines with suitable quantities to increase coverage in all Regions and Autonomous Provinces with extreme urgency. 5) Prepare plans to increase coverage for influenza, pneumococcal, tetanus diphtheria and shingles. The Board of the Calendar for Life appeals to the National and Local Health Authorities for a strong and coordinated commitment in favor of the widest offer and acceptance of vaccinations, whose vital importance for collective health is now even more evident to all, in order to avoid that delays in the necessary initiatives should add damage from other epidemics to those suffered by our population due to the COVID-19 pandemic.

Capecitabine in combination with oxaliplatin or irinotecan in elderly patients with advanced colorectal cancer: results of a randomized phase II study.

BACKGROUND: To determine the efficacy and tolerability of capecitabine combined with oxaliplatin (CAPOX) or irinotecan (CAPIRI) as first-line treatment in patients with advanced/metastatic colorectal cancer aged > or =70 years. PATIENTS AND METHODS: Patients aged > or =70 years were randomly assigned to receive CAPOX [oxaliplatin 65 mg/m(2) intravenously (i.v.) days 1 and 8 and capecitabine 1000 mg/m(2) orally b.i.d. days 1-14; q21d] or CAPIRI (irinotecan 80 mg/m(2) i.v. days 1 and 8 and capecitabine 1000 mg/m(2) orally b.i.d. days 1-14; q21d). The primary study end point was overall response rate (ORR). RESULTS: Ninety-four patients were enrolled. In an intent-to-treat analysis, 2 complete responses (CRs) and 16 partial responses (PRs) were reported with CAPOX (ORR 38%), and 2 CRs and 15 PRs with CAPIRI (ORR 36%; P = 0.831). Median time to progression was 8 months for CAPOX and 7 months for CAPIRI (P = 0.195), with median survival times of 19.3 months and 14.0 months (P = 0.165), respectively. Global health status was improved in 45% and in 21% of patients in the CAPOX and CAPIRI arms, respectively. The most common treatment-related grade 3-4 adverse events in CAPIRI versus CAPOX patients were diarrhea (32% versus 15%; P = 0.052) and neutropenia (23% versus 6%; P = 0.021). CONCLUSION: CAPOX and CAPIRI had similar efficacy in elderly patients, although CAPOX seemed to be better tolerated.

Variation within the CLEC16A gene shows consistent disease association with both multiple sclerosis and type 1 diabetes in Sardinia.

Variation within intron 19 of the CLEC16A (KIAA0350) gene region was recently found to be unequivocally associated with type 1 diabetes (T1D) in genome-wide association (GWA) studies in Northern European populations. A variant in intron 22 that is nearly independent of the intron 19 variant showed suggestive evidence of association with multiple sclerosis (MS). Here, we genotyped the rs725613 polymorphism, representative of the earlier reported associations with T1D within CLEC16A, in 1037 T1D cases, 1498 MS cases and 1706 matched controls, all from the founder, autoimmunity-prone Sardinian population. In these Sardinian samples, allele A of rs725613 is positively associated not only with T1D (odds ratio=1.15, P one-tail=5.1 x 10(-3)) but also, and with a comparable effect size, with MS (odds ratio=1.21, P one-tail 6.7 x 10(-5)). Taken together these data provide evidence of joint disease association in T1D and MS within CLEC16A and underline a shared disease pathway.

Can elderly patients with colorectal cancer tolerate planned surgical treatment? A practical approach to a common dilemma.

AIM: Analysing the effectiveness of a surgical procedure is mandatory in every modern health-care system. The aging of the population stresses the need for a good standard of care. This study tests the hypothesis that porthsmouth-physiologic operative severity score for enumeration of morbidity and mortality (P-POSSUM) and colorectal-POSSUM (CR-POSSUM) would be useful clinical auditing tools in colorectal cancer surgery for aged patients. METHOD: One hundred and seventy-seven consecutive patients over 70 years of age underwent emergency or elective surgery from January 2003 to December 2005. Demographic, clinical and surgical information, score systems' prediction, complications and 30-day mortality data were prospectively entered in a comprehensive database. The observed over expected morbidity and mortality rate was calculated. RESULTS: Thirty-day observed mortality was 10.3% (19/177) while P-POSSUM and CR-POSSUM expected mortality were, respectively, 11.21% (P = NS) and 13.08% (P = NS). Overall observed morbidity was 42.7%, P-POSSUM prediction was 59.3% (P = 0.002). Morbidity and mortality data were analysed for specific subgroups of patients (resection and anastomosis/resection and stoma/palliative; emergency/elective). CONCLUSION: P-POSSUM and CR-POSSUM are useful tools to predict mortality in elderly patients. P-POSSUM significantly overestimated the risk of complications. A more accurate tool for preoperative assessment for aged patients is probably needed to predict the post-surgical outcome.
