Molecular profile and its clinical impact of IDH1 mutated versus IDH1 wild type intrahepatic cholangiocarcinoma

Intrahepatic cholangiocarcinoma; MutationColangiocarcinoma intrahepático; MutaciónColangiocarcinoma intrahepàtic; MutacióIDH1-mutated cholangiocarcinomas (CCAs) are an interesting group of neoplasia with particular behavior and therapeutic implications. The aim of the present work is to highlight the differences characterizing IDH1m and IDH1wt CCAs in terms of genomic landscape. 284 patients with iCCA treated for resectable, locally advanced or metastatic disease were selected and studied with the FOUNDATION Cdx technology. A comparative genomic analysis and survival analyses for the most relevant altered genes were performed between IDH1m and IDH1wt patients. Overall, 125 patients were IDH1m and 122 IDH1wt. IDH1m patients showed higher mutation rates compared to IDH1wt in CDKN2B and lower mutation rates in several genes including TP53, FGFR2, BRCA2, ATM, MAP3K1, NOTCH2, ZNF703, CCND1, NBN, NF1, MAP3KI3, and RAD21. At the survival analysis, IDH1m and IDH1wt patients showed no statistically differences in terms of survival outcomes, but a trend in favor of IDH1wt patients was observed. Differences in prognostic values of the most common altered genes were reported. In surgical setting, in IDH1m group the presence of CDKN2A and CDKN2B mutations negatively impact DFS, whereas the presence of CDKN2A, CDKN2B, and PBRM1 mutations negatively impact OS. In advanced setting, in the IDH1m group, the presence of KRAS/NRAS and TP53 mutations negatively impact PFS, whereas the presence of TP53 and PIK3CA mutations negatively impact OS; in the IDH1wt group, only the presence of MTAP mutation negatively impact PFS, whereas the presence of TP53 mutation negatively impact OS. We highlighted several molecular differences with distinct prognostic implications between IDH1m and IDH1wt patients

TRIPLETE: A randomised phase III study of modified FOLFOXIRI plus panitumumab versus mFOLFOX6 plus panitumumab as initial therapy for patients with unresectable RAS and BRAF wild-type metastatic colorectal cancer

FOLFOXIRI plus bevacizumab is considered a standard option in the upfront treatment of clinically selected patients with metastatic colorectal cancer irrespective of RAS and BRAF molecular status. The randomised MACBETH and VOLFI studies showed that a modified FOLFOXIRI regimen in combination with cetuximab or panitumumab, respectively, achieved high therapeutic activity in RAS and BRAF wild-type patients with an acceptable toxicity profile. Drawing from these considerations, we designed TRIPLETE study aiming at comparing two different chemotherapy backbones (mFOLFOXIRI or mFOLFOX6) in combination with panitumumab in the first-line treatment of patients with RAS and BRAF wild-type metastatic colorectal cancer. Methods This is a prospective, open-label, multicentre phase III trial in which initially unresectable and previously untreated RAS and BRAF wild-type metastatic colorectal cancer patients are randomised to receive a standard treatment with mFOLFOX6 plus panitumumab or an experimental regimen with modified FOLFOXIRI (irinotecan 150 mg/m 2, oxaliplatin 85 mg/m 2, L-leucovorin 200 mg/m 2, 5-fluoruracil 2400 mg/m 2 48-hour continuous infusion) plus panitumumab up to 12 cycles, followed by panitumumab plus 5-fluorouracil and L-leucovorin until disease progression. The primary endpoint is overall response rate according to RECIST 1.1 criteria. Discussion The relative benefit of chemotherapy intensification when using an anti-EGFR-based regimen in molecularly selected patients is unknown; TRIPLETE study aims at filling this gap of knowledge. The study is sponsored by the Gruppo Oncologico Nord Ovest Cooperative Group and is currently ongoing at 42 Italian centres. Clinical trial information NCT03231722

Impact of the time interval between primary or interval surgery and adjuvant chemotherapy in ovarian cancer patients

IntroductionPrimary debulking surgery (PDS), interval debulking surgery (IDS), and platinum-based chemotherapy are the current standard treatments for advanced ovarian cancer (OC). The time to initiation of adjuvant chemotherapy (TTC) could influence patient outcomes.MethodsWe conducted a multicenter retrospective cohort study of advanced (International Federation of Gynecology and Obstetrics (FIGO) stage III or IV) OC treated between 2014 and 2018 to assess progression-free survival (PFS) and overall survival (OS) in relation to TTC. All patients underwent a germline multigene panel for BRCA1/2 evaluation.ResultsAmong the 83 patients who underwent PDS, a TTC ≥ 60 days was associated with a shorter PFS (hazard ratio (HR) 2.02, 95% confidence interval (CI) 1.04–3.93, p = 0.038), although this association lost statistical significance when adjusting for residual disease (HR 1.52, 95% CI 0.75–3.06, p = 0.244, for TTC and HR 2.73, 95% CI 1.50–4.96, p = 0.001, for residual disease). Among 52 IDS patients, we found no evidence of an association between TTC and clinical outcomes. Ascites, type of chemotherapy, or germline BRCA1/2 mutational status did not influence TTC and were not associated with clinical outcomes in PDS or IDS patients.DiscussionIn conclusion, longer TTC seems to negatively affect prognosis in patients undergoing PDS, especially those with residual disease

Real Life Study of Lenvatinib Therapy for Hepatocellular Carcinoma: RELEVANT Study

Introduction: In the REFLECT trial, lenvatinib was found to be noninferior compared to sorafenib in terms of overall survival. Here, we analyze the effects of lenvatinib in the real-life experience of several centers across the world and identify clinical factors that could be significantly associated with survival outcomes. Methods: The study population was derived from retrospectively collected data of HCC patients treated with lenvatinib. The overall cohort included western and eastern populations from 23 center in five countries. Results: We included 1,325 patients with HCC and treated with lenvatinib in our analysis. Median OS was 16.1 months. Overall response rate was 38.5%. Multivariate analysis for OS highlighted that HBsAg positive, NLR >3, and AST >38 were independently associated with poor prognosis in all models. Conversely, NAFLD/NASH-related etiology was independently associated with good prognosis. Median progression-free survival was 6.3 months. Multivariate analysis for progression-free survival revealed that NAFLD/NASH, BCLC, NLR, and AST were independent prognostic factors for progression-free survival. A proportion of 75.2% of patients suffered from at least one adverse effect during the study period. Multivariate analysis exhibited the appearance of decreased appetite grade ≥2 versus grade 0-1 as an independent prognostic factor for worse progression-free survival. 924 patients of 1,325 progressed during lenvatinib (69.7%), and 827 of them had a follow-up over 2 months from the beginning of second-line treatment. From first-line therapy, the longest median OS was obtained with the sequence lenvatinib and immunotherapy (47.0 months), followed by TACE (24.7 months), ramucirumab (21.2 months), sorafenib (15.7 months), regorafenib (12.7 months), and best supportive care (10.8 months). Conclusions: Our study confirms in a large and global population of patients with advanced HCC, not candidates for locoregional treatment the OS reported in the registration study and a high response rate with lenvatinib

Sequential therapies after atezolizumab plus bevacizumab or lenvatinib first-line treatments in hepatocellular carcinoma patients

Introduction: The aim of this retrospective proof-of-concept study was to compare different second-line treatments for patients with hepatocellular carcinoma and progressive disease (PD) after first-line lenvatinib or atezolizumab plus bevacizumab.Materials and methods: A total of 1381 patients had PD at first-line therapy. 917 patients received lenvatinib as first-line treatment, and 464 patients atezolizumab plus bevacizumab as first-line.Results: 49.6% of PD patients received a second-line therapy without any statistical difference in overall survival (OS) between lenvatinib (20.6 months) and atezolizumab plus bev-acizumab first-line (15.7 months; p = 0.12; hazard ratio [HR] = 0.80). After lenvatinib first-line, there wasn't any statistical difference between second-line therapy subgroups (p = 0.27; sorafenib HR: 1; immunotherapy HR: 0.69; other therapies HR: 0.85). Patients who under-went trans-arterial chemo-embolization (TACE) had a significative longer OS than patients who received sorafenib (24.7 versus 15.8 months, p < 0.01; HR = 0.64). After atezolizumab plus bevacizumab first-line, there was a statistical difference between second-line therapy subgroups (p < 0.01; sorafenib HR: 1; lenvatinib HR: 0.50; cabozantinib HR: 1.29; other therapies HR: 0.54). Patients who received lenvatinib (17.0 months) and those who under-went TACE (15.9 months) had a significative longer OS than patients treated with sorafenib (14.2 months; respectively, p = 0.01; HR = 0.45, and p < 0.05; HR = 0.46).Conclusion: Approximately half of patients receiving first-line lenvatinib or atezolizumab plus bevacizumab access second-line treatment. Our data suggest that in patients progressed to atezolizumab plus bevacizumab, the systemic therapy able to achieve the longest survival is lenvatinib, while in patients progressed to lenvatinib, the systemic therapy able to achieve the longest survival is immunotherapy

Le patologie oncoematologiche pediatriche

Nel pensare alla contestualizzazione della Psicologia pediatrica all’interno di questo capitolo, si è voluto assumere la prospettiva che appare oggi attuale e che conduce a non considerare le neoplasie come patologie croniche. Ciò vuol dire pensare alla possibilità della guarigione e non solo alla sopravvivenza; in tal senso, si intende assumere la Dichiarazione di Erice (Jankovic et al., 2007), con cui si asserisce che “il concetto di guarigione di un tumore pediatrico si riferisce solo alla malattia iniziale, indipendentemente dall’eventuale rischio o presenza di invalidità o di effetti collaterali delle terapie; i bambini che sono stati curati per un tumore possono essere considerati “guariti” quando hanno raggiunto il momento in cui la loro probabilità di morire non sia più grande di quella dei loro coetanei”. Lo sviluppo di questa prospettiva della guarigione così come la condivisione di linee guida (Masera et al., 1996; Spinetta et al., 2009) di ispirazione medico-psicologica, ha trovato nell’A.I.E.O.P. (Associazione Italiana Ematologia ed Oncologia Pediatrica) e nel gruppo di lavoro psicosociale di riferimento un’implementazione intenzionale che ha orientato il lavoro all’interno dei diversi centri di Ematologia e Oncologia pediatrica che afferiscono all’associazione. L’assunzione della prospettiva della guarigione risulta fondamentale per la Psicologia pediatrica, pur nella consapevolezza di quanto questa prospettiva sia ancora una tematica di dibattito sociale e ponga ancora alcuni dubbi anche agli stessi operatori del settore, “ come quando si rifiuta la certificazione di guarito ad un giovane che da adolescente è stato affetto da tumore e che oggi, giovane uomo, desidera diventare un pilota di linea”

Coping strategies and locus of control in children suffering from Acute Lymphoblastic Leukemia

Introduction The start of the treatment phase of Acute Lymphoblastic Leukemia (ALL) diagnosis represents an emotional distress condition for the child (Hildenbrand et al., 2011), which requires to use some resources to manage this condition in an adaptive way, one of these resources is represented of coping strategies. The study focuses on children’s coping strategies according to the model of Miller (1987; Miller et al., 1995), which distinguishes between two specific directions, monitoring and blunting. At the same time, the study presents an innovative aspect focusing on the relationship between coping and locus of control, as well as the possible mirroring between child’s and his mother’s coping strategies. Objective The study investigates correlations between coping strategies and locus of control in children suffering from Acute Lymphoblastic Leukemia. At the same time, it investigates correlations between children’s and their mothers’ coping strategies. Method The study was performed within a group of 20 children suffering from Acute Lymphoblastic Leukemia at the start of the treatment phase and their mothers. The used tools were: Monitor Blunter Style Scale (Miller, 1987); Child Behavioral Style Scale (Phipps, Fairclough, Mulhern, 1995); Locus of Control Scale for Children (Nowicki, Strickland, 1973). Results The data were analyzed by non-parametric statistics (Spearman's r). They highlight statistically significant correlations only between child’s monitoring coping strategies and external locus of control (r=.645; p<.01); on the descriptive level prevail active coping strategies (monitoring: =18,35; blunting: =13,55) and external locus of control (internal: =51,9; external: =39,05). There aren’t statistically significant correlations between child’s and his mother’s coping strategies. Conclusions Results show some interesting correlations between several variables of child’s psychological functioning, which would require further investigation
