Abstract
Single immune checkpoint blockade in advanced neuroendocrine neoplasms (NENs) shows limited efficacy; dual checkpoint blockade may improve treatment activity. Dune (NCT03095274) is a non-randomized controlled multicohort phase II clinical trial evaluating durvalumab plus tremelimumab activity and safety in advanced NENs. This study included 123 patients presenting between 2017 and 2019 with typical/atypical lung carcinoids (Cohort 1), G1/2 gastrointestinal (Cohort 2), G1/2 pancreatic (Cohort 3) and G3 gastroenteropancreatic (GEP) (Cohort 4) NENs; who progressed to standard therapies. Patients received 1500 mg durvalumab and 75 mg tremelimumab for up to 13 and 4 cycles (every 4 weeks), respectively. The primary objective was the 9-month clinical benefit rate (CBR) for cohorts 1-3 and 9-month overall survival (OS) rate for Cohort 4. Secondary endpoints included objective response rate, duration of response, progression-free survival according to irRECIST, overall survival, and safety. Correlation of PD-L1 expression with efficacy was exploratory. The 9-month CBR was 25.9%/35.5%/25% for Cohorts 1, 2, and 3 respectively. The 9-month OS rate for Cohort 4 was 36.1%, surpassing the futility threshold. Benefit in Cohort 4 was observed regardless of differentiation and Ki67 levels. PD-L1 combined scores did not correlate with treatment activity. Safety profile was consistent with that of prior studies. In conclusion, durvalumab plus tremelimumab is safe in NENs and shows modest survival benefit in G3 GEP-NENs; with one-third of these patients experiencing a prolonged OS.

Trifluridine/tipiracil in combination with oxaliplatin and either bevacizumab or nivolumab in metastatic colorectal cancer: a dose-expansion, phase I study. ESMO Open 2021; 6:100270. [PMID: 34547581 PMCID: PMC8453191 DOI: 10.1016/j.esmoop.2021.100270] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/11/2021] [Revised: 08/13/2021] [Accepted: 08/20/2021] [Indexed: 02/07/2023] Open
Abstract
Background In preclinical studies trifluridine/tipiracil (FTD/TPI) plus oxaliplatin (Industriestrasse, Holzkirchen, Germany) sensitised microsatellite stable (MSS) metastatic colorectal cancer (mCRC) to anti-programmed cell death protein-1; the addition of oxaliplatin or bevacizumab (F Hoffmann- la ROCHE AG, Kaiseraugst, Switzerland) enhanced the antitumour effects of FTD/TPI. This study aimed to investigate the safety and efficacy of FTD/TPI plus oxaliplatin and either bevacizumab or nivolumab (Uxbridge business Park, Uxbridge, United Kingdom) in patients with mCRC who had progressed after at least one prior line of treatment. Patients and methods In 14-day cycles, patients received FTD/TPI 35 mg/m2 (twice daily, days 1-5) plus oxaliplatin 85 mg/m2 (day 1), and, on day 1, either bevacizumab 5 mg/kg (cohort A) or nivolumab 3 mg/kg (cohort B). Patients in Cohort B had confirmed MSS status. Results In total, 54 patients were enrolled: 37 in cohort A and 17 in cohort B. Recruitment in cohort B was stopped early due to the low response rate (RR) observed at interim analyses of efficacy. The most common adverse events (AEs) in cohort A were neutropenia/decreased neutrophils (75.7%), nausea (59.5%), vomiting (40.5%), diarrhoea (37.8%), peripheral sensory neuropathy (37.8%), fatigue (35.1%) and decreased appetite (35.1%). In cohort B, the most common AEs were neutropenia/decreased neutrophils (70.6%), diarrhoea (58.8%), nausea (47.1%), vomiting (47.1%), fatigue (47.1%), asthenia (41.2%), paraesthesia (41.2%), thrombocytopenia/decreased platelets (35.3%) and decreased appetite (35.3%). Confirmed objective RR was 17.1% in cohort A and 7.1% in cohort B; the corresponding values for median progression-free survival in the two cohorts were 6.3 and 6.0 months. Conclusion FTD/TPI plus oxaliplatin and bevacizumab or nivolumab had an acceptable safety profile and demonstrated antitumour activity in previously treated patients with mCRC. This study evaluated the safety and efficacy of FTD/TPI plus oxaliplatin and either bevacizumab or nivolumab in mCRC patients. FTD/TPI plus oxaliplatin in combination with bevacizumab or nivolumab had an acceptable and manageable safety profile. Antitumour activity was observed following treatment with FTD/TPI plus oxaliplatin and bevacizumab. Despite a modest RR with the addition of nivolumab, survival data were promising in these poor-prognosis patients.

Abstract
Functional magnetic resonance imaging studies (fMRI) in children with Attention Deficit Hyperactivity Disorder (ADHD) have observed functional abnormalities in fronto-striatal and temporo-parietal brain regions during tasks of inhibitory and attention control. However, hardly any modern functional imaging studies have investigated functions of interference inhibition or attention control in adult ADHD.We used fMRI combined with a variant of the Simon task that measures interference inhibition as well as attention allocation to compare 11 medication-naïve adults (26-30 yrs) with inattentive/hyperactive behaviours and 15 age-matched healthy controls. Patients were followed up from childhood ADHD, recruited from a 20-year prospective longitudinal epidemiological study. All met criteria for inattentive/hyperactive behaviours on an Adult Hyperactive Interview, but only 8 met clinical diagnostic criteria for ADHD. Correlation analyses were furthermore conducted within patients to correlate symptoms with brain activation. Functional connectivity analyses for group differences in fronto-striatal connectivity will be presented at the conference.No differences were observed in task performance. During interference inhibition, adults with persistent inattentive/hyperactive compared to controls showed reduced activation in predominantly left orbitofrontal and medial cortex, caudate and putamen. During attention allocation adults with hyperactive behaviours showed dysfunction in left inferior/dorsolateral prefrontal cortex and in right inferior and superior parietal areas. Correlation analysis showed a significant negative correlation between inattentive/hyperactive behaviours and the parietal activation cluster during interference inhibition. The study demonstrates the continuity of the pattern of fronto-striatal and parietal neurofunctional abnormalities during tasks of interference inhibition and attention allocation from childhood to adult ADHD even with symptomatic improvement.

Abstract
PURPOSE/OBJECTIVE(S) To improve the curative resection rates and prognoses, a variety of neoadjuvant (NA) strategies have been explored in PDAC. In our institution, non-metastatic PDACs have been treated with a NA intent with induction multiagent chemotherapy and SBRT. The primary endpoint was to increase R0 resection rate. The secondary endpoints were the analysis of the clinical tolerance, the pathological response, the local control (LC) and the OS. MATERIALS/METHODS All consecutive patients with non-metastatic PDAC underwent SBRT as part of the NA strategy were included. A total dose of 40-62 Gy were delivered in 5-10 fractions. Surgery was performed after SBRT and restaging. RESULTS Since February 2014 to December 2018, 45 patients were enrolled. Thirty-two patients underwent surgery (71.1%), 10 out of 15 were initially unresectable disease patients (66.75%). R0 resection rate was 93% (30 patients) and pN0 status was achieved in 20 patients (60.6%). Tumour regression grade (TRG): 12 patients with complete response or marked response (TRG 0-1: 37.5%), 16 patients with moderate response (TRG 2: 50%) and four patients with poor response (TRG 3: 12.5%). The median follow-up was 16.2 m (range 6.6-59.6 m) since diagnosis. The LC rate achieved was very high (95.5%). Actuarial 12 and 24 m OS was 67.4% and 35.9% respectively. No grade 3 or higher toxicity related to SBRT was observed. CONCLUSION The results are encouraging, suggesting that SBRT has a significant role in the management of these patients and further studies will be necessary to prove these findings.

Abstract
Nanoliposomal irinotecan (nal‐IRI) is a liposomal formulation of irinotecan with a longer half‐life (t1/2), higher plasma total irinotecan (tIRI), and lower SN‐38 maximum concentration (Cmax) compared with nonliposomal irinotecan. Population pharmacokinetic (PK) analysis of nal‐IRI was performed for tIRI and total SN‐38 (tSN38) using patient samples from six studies. PK‐safety association was evaluated for neutropenia and diarrhea in 353 patients. PK‐efficacy association was evaluated from a phase III study in pancreatic cancer NAPOLI1. Efficacy was associated with longer duration of unencapsulated SN‐38 (uSN38) above a threshold and higher Cavg of tIRI, tSN38, and uSN38. Neutropenia was associated with uSN38 Cmax and diarrhea with tIRI Cmax. Baseline predictive factors were race, body surface area, and bilirubin. Analysis identified PK factors associated with efficacy, safety, and predictive baseline factors. The results support the benefit of nal‐IRI dose of 70 mg/m2 (free‐base; equivalent to 80 mg/m2 salt base) Q2W over 100 mg/m2 Q3W.

Abstract
BACKGROUND The catecholamine reuptake inhibitors methylphenidate (MPH) and atomoxetine (ATX) are the most common treatments for attention deficit hyperactivity disorder (ADHD). This study compares the neurofunctional modulation and normalization effects of acute doses of MPH and ATX within medication-naive ADHD boys during working memory (WM). METHOD A total of 20 medication-naive ADHD boys underwent functional magnetic resonance imaging during a parametric WM n-back task three times, under a single clinical dose of either MPH, ATX or placebo in a randomized, double-blind, placebo-controlled, cross-over design. To test for normalization effects, brain activations in ADHD under each drug condition were compared with that of 20 age-matched healthy control boys. RESULTS Relative to healthy boys, ADHD boys under placebo showed impaired performance only under high WM load together with significant underactivation in the bilateral dorsolateral prefrontal cortex (DLPFC). Both drugs normalized the performance deficits relative to controls. ATX significantly enhanced right DLPFC activation relative to MPH within patients, and significantly normalized its underactivation relative to controls. MPH, by contrast, both relative to placebo and ATX, as well as relative to controls, upregulated the left inferior frontal cortex (IFC), but only during 2-back. Both drugs enhanced fronto-temporo-striatal activation in ADHD relative to control boys and deactivated the default-mode network, which were negatively associated with the reduced DLPFC activation and performance deficits, suggesting compensation effects. CONCLUSIONS The study shows both shared and drug-specific effects. ATX upregulated and normalized right DLPFC underactivation, while MPH upregulated left IFC activation, suggesting drug-specific laterality effects on prefrontal regions mediating WM.

Stromal disrupting effects of nab-paclitaxel in pancreatic cancer. Br J Cancer 2013; 109:926-33. [PMID: 23907428 PMCID: PMC3749580 DOI: 10.1038/bjc.2013.415] [Citation(s) in RCA: 254] [Impact Index Per Article: 23.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/25/2013] [Revised: 06/26/2013] [Accepted: 07/01/2013] [Indexed: 12/12/2022] Open
Abstract
Background: Nab-paclitaxel and gemcitabine have demonstrated a survival benefit over gemcitabine alone in advanced pancreatic cancer (PDA). This study aimed to investigate the clinical, biological, and imaging effects of the regimen in patients with operable PDA. Methods: Patients with operable PDA received two cycles of nab-paclitaxel and gemcitabine before surgical resection. FDG-PET and CA19.9 tumour marker levels were used to measure clinical activity. Effects on tumour stroma were determined by endoscopic ultrasound (EUS) elastography. The collagen content and architecture as well as density of cancer-associated fibroblasts (CAFs) were determined in the resected surgical specimen and compared with a group of untreated and treated with conventional chemoradiation therapy controls. A co-clinical study in a mouse model of PDA was conducted to differentiate between the effects of nab-paclitaxel and gemcitabine. Results: A total of 16 patients were enrolled. Treatment resulted in significant antitumour effects with 50% of patients achieving a >75% decrease in circulating CA19.9 tumour marker and a response by FDG-PET. There was also a significant decrement in tumour stiffness as measured by EUS elastography. Seven of 12 patients who completed treatment and were operated had major pathological regressions. Analysis of residual tumours showed a marked disorganised collagen with a very low density of CAF, which was not observed in the untreated or conventionally treated control groups. The preclinical co-clinical study showed that these effects were specific of nab-paclitaxel and not gemcitabine. Conclusion: These data suggest that nab-paclitaxel and gemcitabine decreases CAF content inducing a marked alteration in cancer stroma that results in tumour softening. This regimen should be studied in patients with operable PDA.

Abstract
A high throughput screening for anticancer activity of FDA approved drugs identified mycophenolic acid (MPA), an inhibitor of inositol monophosphate dehydrogenase (IMPDH) as an active agent with an antiangiogenesis mode of action. Exposure of pancreatic cancer cell lines to MPA resulted in growth inhibition and reduced the expression of VEGF that was reversed by supplementing the media with guanosine supporting and IMPDH-dependant mechanism. In preclinical in vivo study, MPA showed a moderate inhibition of tumor growth in a panel of 6 human derived pancreatic cancer xenografts but reduced the expression of VEGF. To investigate the effects of MPA in human pancreatic cancer, a total of 12 patients with resectable pancreatic cancer (PDA) received increasing doses of mycophenolate mofetil (MMF) in cohorts of 6 patients each from 5-15 days prior to surgical resection. Treatment was well tolerated with one episode of grade 1 muscle pain, one episode of grade 2 lymphopenia (2 gr/day dose) and one episode of grade 2 elevantion in LFT (all in the 2 gr./day dose). Patients recovered from surgery uneventfully with no increased post-operative complications. Assessment of CD31, VEGF, and TUNEL in resected specimens compared to a non treated control of 6 patients showed no significant variations in any of the study endpoints. In conclusion, this study shows the feasibility of translating a preclinical observation to the clinical setting and to explore a drug mechanism of action in patients. MPA, however, did not show any hints of antiangiogenesis of anticancer clinical activity questioning if this agent should be further developed in PDA.

Abstract
11074 Background: Treatment options for patients (pts) with colorectal cancer (CRC) have increased in the last years. However, there are no validated prospective molecular markers in CRC to select which agents are better to treat any individual case. The aim of this study was to determine the feasibility of developing an implementing a biomarker panel to guide treatment selection in this setting. Methods: Colorectal cancer tumors were prospectively analyzed with a predefined set of 11 molecular targets, including: KRas and PI3K mutations, EGFR amplification (FISH), and ERCC-1, TS, TP expression by IHC. Clinical characteristics and response to chemotherapy were registered. To establish the utility of this panel, we determine as congruent-treatment if the panel predict the best treatment in patients with more of 1 chemotherapy line and no-congruent-treatment if do not. Results: A total of 84 patients were studied. Only 6 % required a repeated biopsy to obtain sufficient tumor for marker analysis. In 81 % of patients was feasible to study almost 8/11 targets. There were 29 pts (39%) with KRas mutant CRC; 3 pts with PI3K mutations (4%, all of them with KRas mutation); and 2 patients with EGFR amplification. ERCC-1 was positive in 5/78 (6.4%) and TS was positive in 47%. None of 54 pts had TP positivity. Clinical floow up was available in 66 pts (44 males, median age 59, 93% ECOG 0–1). Nineteen patients had early CRC; 23 with metastatic CRC treated with a first line chemotherapy and 24 with advanced CRC treated with 2 or more prior regimens. In this last group for whom the response to multiple agents is known, the panel predictive the most effective treatment in 14 of 24 cases. Conclusions: This targeted-therapy-panel is feasible to implement and should be explore to predict treatment response to CRC . No significant financial relationships to disclose.

Abstract
Attention Deficit Hyperactivity Disorder (ADHD) in children has been associated with functional abnormalities in fronto-striatal brain regions during tasks of inhibitory control. In adults with ADHD, however, no functional magnetic resonance imaging (fMRI) study has investigated the neurofunctional correlates of the most compromised cognitive functions of motor response inhibition or cognitive flexibility.fMRI was used combined with a tracking Stop task of motor response inhibition and a cognitive Switch task to compare brain function between 11 medication-naïve adults (26-30 yrs) with inattentive/hyperactive behaviours and 14 age-matched healthy controls. Patients were followed up from childhood ADHD, recruited from a 20-year prospective longitudinal epidemiological study. All met criteria for inattentive/hyperactive behaviours on an Adult Hyperactive Interview, but only 8 met clinical diagnostic criteria for ADHD. Whole brain regression MR analyses were furthermore conducted within patients to correlate symptoms with brain activation. Functional connectivity analyses for group differences in fronto-striatal connectivity will be presented at the conference.Despite comparable task performance, adults with persistent inattentive/hyperactive behaviours showed reduced activation compared to controls in inferior prefrontal cortex, caudate and thalamus during both tasks, as well as in parietal lobes during the Switch task. Regression analyses furthermore showed a linear negative correlation between behavioural symptoms and overlapping, but more extensive fronto-striatal, parietal and cerebellar brain dysfunction. The findings demonstrate for the first time the persistence of the typical childhood ADHD pattern of fronto-striatal dysfunction during tasks of cognitive control in adults with persisting behavioural symptoms, suggesting stability/continuity of neurofunctional abnormalities between childhood and early adulthood.

Abstract
INTRODUCTION Several different follow-up studies have shown that attention deficit hyperactivity disorder (ADHD) can persist into adulthood. AIM To review the findings in adults with ADHD related to alterations in the executive functions. DEVELOPMENT Research conducted among children with ADHD has revealed the existence of alterations in different tasks that evaluate the executive functions, such as the planning test, sustained attention tasks, cognitive flexibility, verbal fluency and working memory tasks, as well as several inhibition response tasks. In adults with ADHD, despite the lower number of reports in the literature and the methodological shortcomings that exist in some studies, analogous results have also been described with respect to executive functioning, namely, disorders affecting inhibition response, the capacity for planning, difficulties in cognitive flexibility and verbal fluency, and problems with working memory, which include aspects of spatial working memory, logical or visual memory. CONCLUSIONS The findings we have available at present enable us to confirm the persistence of executive dysfunctions in adult patients with ADHD that are similar to those observed in children with ADHD.

Abstract
The purpose of this study was to evaluate cisplatin nephrotoxicity in patients 70 years and older and to identify factors influencing nephrotoxicity occurrence. Forty-nine (N = 49) patients older than 70 years were studied retrospectively. All patients received treatment with cisplatin. Variables under study were as follows: prechemotherapy serum creatinine levels (Crb), maximum serum creatinine level during treatment (Crmax), steady serum creatinine level 3 months after treatment completion (Crstb), as well as their corresponding creatinine clearance values (CrbC, CrmaxC, CrstbC) as calculated by the Cockroft and Gault formula. Maximum creatinine increment (Imax = Crmax - Crb), stable creatinine increment (Istb = Crstb - Crb) and the corresponding clearance decrements (Dmax and Dstb) were calculated as well. The potential relationship of the above variables to cisplatin dose intensity and accumulated dose as well as to different prognostic factors were also considered. Assessment of associated conditions was carried out by means of Charlson comorbidity index. The patients' mean age was 73 years (range: 70-79 years). There were 43 men (88%) and 6 women (12%). Mean cisplatin dose intensity was 27 mg/m2/wk. A total of 157 chemotherapy courses were administered with a mean of 3.2 per patient. Mean Crb was 1.02 mg/dl (95% CI = 1.02-1.12), mean Crmax was 1.45 (95% CI = 1.34-1.46), and mean Crstb was 1.24 (95% CI = 1.16-1.32). Imax was equal to 0 in 13 patients (26%) and more than 0.4 mg/dl in 21 patients (43%). Istb was equal to 0 or negative in 22 (45%) and more than 0.4 in only 9 patients (18.3%). No significant relationship of serum creatinine levels, creatinine clearance levels, or of their increments or decrements to cisplatin dose intensity or accumulated dose were found. These levels also did not correlate with age, sex, comorbidity or Eastern Cooperative Oncology Group score. In 85% of patients, Crmax was reached between chemotherapy initiation and the third chemotherapy course, and thereafter renal function began to recover despite continued administration of cisplatin. Cisplatin is well tolerated by patients 70 years and older and dose intensity does not seem to influence renal function deterioration. Therefore, we failed to find reasons to encourage modification or limitation of cisplatin treatment in the elderly population.

Abstract
The new biodegradable interference screws offer very many advantages for anterior cruciate ligament replacement with patellar tendon. However, their radiolucency makes it impossible to identify the anchorage sites. We describe an imaging technique of the plasty and its anchorage sites by means of a radiopaque contrast that is commonly used in radiology (Iopamidol; Bracco, Milan, Italy). It is an easy technique that does not extend the time of surgery, it is harmless, and allows us to identify malpositioning or impingement of the plasty.
