RESUMO

Purpose: Testicular cancer (TC) is the most common solid tumor in young adults. 95% of patients are cured, but they may experience late adverse effects (anxiety, fear of recurrence, and sexual dysfunction) with an impact on daily life. We attempted to assess Patient Reported Outcomes (PROMs), long-term sexual disorders, and difficulties in achieving fatherhood in a cohort of TC survivors, as well as their possible correlation with previous cancer treatments. Methods: Different questionnaires, such as the Impact of Cancer (IOC) and the Body Image Scale (BIS), were used to investigate the distinct areas of the PROMs. International Index of Erectile Function (IIEF15) and the Premature Ejaculation Diagnostic Tool (PEDT) focused on sexuality and fertility. Patients were prospectively recruited between February 2020 and February 2022. Results: 144 participants completed all the questionnaires. Results showed a good QoL, a moderate fear of TC recurrence, a good satisfaction with their personal body image, low incidence of premature ejaculation and erectile dysfunction. 19.5% of patients who had a testicular implant reported general dissatisfaction. Only 18% of patients had unsuccessfully attempted fatherhood, while the majority had not yet tried, and 23.4% succeeded. A low percentage of patients used procedures assisted reproduction and adoption. Conclusion: This trial supports the use of various questionnaires as a multifactorial tool capable of investigating all the aspects of long-term cancer survivorship. The assessment of medical and psychosocial sequelae is an essential part of patient care and is important for the development of a comprehensive care plan for TC survivors.

RESUMO

BACKGROUND: Few data are available on the safety of COVID-19 vaccines in cancer patients undergoing active cancer-directed treatment. PATIENTS AND METHODS: This case series analyzes outcomes in terms of adverse events in 5297 patients undergoing anti-cancer treatment who were vaccinated with anti-SARS-CoV-2 Pfizer-BioNTech vaccine at a single cancer center from March 6, 2021 to May 9, 2021. Adverse events were retrieved from the national Italian pharmacovigilance platform (http://www.vigicovid.it). RESULTS: Of the 5297 patients treated for either solid tumors (87%) or onco-hematologic malignancies (13%) who were vaccinated, 8 adverse drug reactions (ADRs) were reported. One was a severe ADR and 7 were non-severe ADRs. Non-severe ADRs resolved within 48 hours. CONCLUSION: BNT162b2 Pfizer-BioNTech vaccine was safely administered in the largest cohort of cancer patients reported to date.

RESUMO

OBJECTIVE: The use of regorafenib in recurrent glioblastoma patients has been recently approved by the Italian Medicines Agency (AIFA) and added to the National Comprehensive Cancer Network (NCCN) 2020 guidelines as a preferred regimen. Given its complex effects at the molecular level, the most appropriate imaging tools to assess early response to treatment is still a matter of debate. Diffusion-weighted imaging and O-(2-18F-fluoroethyl)-L-tyrosine positron emission tomography ([18F]FET PET) are promising methodologies providing additional information to the currently used RANO criteria. The aim of this study was to evaluate the variations in diffusion-weighted imaging/apparent diffusion coefficient (ADC) and [18F]FET PET-derived parameters in patients who underwent PET/MR at both baseline and after starting regorafenib. METHODS: We retrospectively reviewed 16 consecutive GBM patients who underwent [18F]FET PET/MR before and after two cycles of regorafenib. Patients were sorted into stable (SD) or progressive disease (PD) categories in accordance with RANO criteria. We were also able to analyze four SD patients who underwent a third PET/MR after another four cycles of regorafenib. [18F]FET uptake greater than 1.6 times the mean background activity was used to define an area to be superimposed on an ADC map at baseline and after treatment. Several metrics were then derived and compared. Log-rank test was applied for overall survival analysis. RESULTS: Percentage difference in FET volumes correlates with the corresponding percentage difference in ADC (R = 0.54). Patients with a twofold increase in FET after regorafenib showed a significantly higher increase in ADC pathological volume than the remaining subjects (p = 0.0023). Kaplan-Meier analysis, performed to compare the performance in overall survival prediction, revealed that the percentage variations of FET- and ADC-derived metrics performed at least as well as RANO criteria (p = 0.02, p = 0.024 and p = 0.04 respectively) and in some cases even better. TBR Max and TBR mean are not able to accurately predict overall survival. CONCLUSION: In recurrent glioblastoma patients treated with regorafenib, [18F]FET and ADC metrics, are able to predict overall survival and being obtained from completely different measures as compared to RANO, could serve as semi-quantitative independent biomarkers of response to treatment. ADVANCES IN KNOWLEDGE: Simultaneous evaluation of [18F]FET and ADC metrics using PET/MR allows an early and reliable identification of response to treatment and predict overall survival.

RESUMO

BACKGROUND: Regorafenib has been shown to improve clinical outcomes compared to placebo, becoming a standard second-line therapy for sorafenib-progressed and -tolerated hepatocellular carcinoma (HCC) patients. OBJECTIVE: We performed a multicentre, retrospective study in Italy and Korea to evaluate the effectiveness of the treatment sequence sorafenib-regorafenib compared with sorafenib and physician's choice in a real-life setting. PATIENTS AND METHODS: A propensity score model was developed to control the results for baseline variable imbalances between the arm treated with sorafenib and regorafenib (S-R) and the arm treated with sorafenib and physician's choice (S-P). Survival analysis was conducted on the matched population. RESULTS: After the application of propensity score matching, we analysed 99 patients in the arm treated with S-R and 99 patients in the arm treated with S-P. For the S-R group, the median overall survival was 22.2 months (95% CI 17.1-27.4), compared to 17.9 months (95% CI 15.1-50.0) for the S-P group. The results of the univariate analysis showed a 31% reduction of death risk for patients treated with S-R (p = 0.0382) compared to patients treated with S-P. Interaction tests highlighted the predictive role of alpha-fetoprotein (AFP), neutrophil-to-lymphocyte ratio (NLR), and extrahepatic spread. CONCLUSION: This study provides additional proof of the superiority of the S-R treatment over the S-P treatment approach in advanced HCC patients from a real-life setting.

RESUMO

BACKGROUND: Inflammation is a long-established hallmark of liver fibrosis and carcinogenesis. Eosinophils are emerging as crucial components of the inflammatory process influencing cancer development. The role of blood eosinophils in patients with hepatocellular carcinoma receiving systemic treatment is an unexplored field. OBJECTIVE: The objective of this study was to analyse the prognostic role of the baseline eosinophil count in patients with sorafenib-treated hepatocellular carcinoma. PATIENTS AND METHODS: A training cohort of 92 patients with advanced- or intermediate-stage sorafenib-treated hepatocellular carcinoma and two validation cohorts of 65 and 180 patients were analysed. Overall survival and progression-free survival in relation to baseline eosinophil counts were estimated by the Kaplan-Meier method. Univariate and multivariate analyses were performed. RESULTS: A negative prognostic impact of low baseline eosinophil counts (< 50*109/L) was demonstrated in all cohorts (training cohort: hazard ratio = 50.1, 95% confidence interval 11.6-216.5, p < 0.0001 for low vs high eosinophil counts; first validation cohort: hazard ratio = 4.55, 95% confidence interval 1.24-16.65, p = 0.022; second validation cohort: hazard ratio = 3.21, 95% confidence interval 1.83-5.64, p < 0.0001). Moreover, low eosinophil counts had a negative prognostic role in patients progressing on or intolerant to sorafenib who received second-line regorafenib, but not capecitabine or best supportive care. CONCLUSIONS: Our analysis identified baseline blood eosinophil counts as a new prognostic factor in patients with sorafenib-treated hepatocellular carcinoma. Concerning second-line therapies, eosinophil counts were associated with survival outcomes only in regorafenib-treated patients, suggesting a possible predictive role in this setting.

RESUMO

Sorafenib is the first multikinase inhibitor demonstrating a survival benefit for patients suffering from advanced hepatocellular carcinoma (HCC). However, 1 issue remains open: what is the factor able to predict which patients will be long survivors?In the present study, we harnessed the potential of conditional survival, aiming at estimating the probability that a patient receiving sorafenib survives for more than 3 years.The present multicentric study was conducted on a cohort of 438 HCC patients. The primary end point was conditional overall survival. Kaplan-Meier survival analysis was used to calculate conditional overall survival probabilities at 3 years.The 3-year conditional survival of patients without disease progression highlights that NLR and ECOG are the factors that most accurately predict the probability of long survival. The 3-year conditional survival of patients with disease progression showed a medium effect size for HCV status, alpha-fetoprotein and NLR at all time-points. Macro-vascular portal vein invasion, extra hepatic disease, and BCLC we have a large effect size at 6 months and a medium effect size at 12 and 24 months.Our findings support the use of baseline NLR for the identification of patients with a higher probability of long-survival. NLR should be used as a stratification factor in the forthcoming clinical trials on the drugs for the advanced HCC now in pipeline.

RESUMO

BACKGROUND: The triplet FOLFOXIRI (fluorouracil, leucovorin, oxaliplatin, and irinotecan) plus bevacizumab showed improved outcomes for patients with metastatic colorectal cancer, compared with FOLFIRI (fluorouracil, leucovorin, and irinotecan) plus bevacizumab. However, the actual benefit of the upfront exposure to the three cytotoxic drugs compared with a preplanned sequential strategy of doublets was not clear, and neither was the feasibility or efficacy of therapies after disease progression. We aimed to compare a preplanned strategy of upfront FOLFOXIRI followed by the reintroduction of the same regimen after disease progression versus a sequence of mFOLFOX6 (fluorouracil, leucovorin, and oxaliplatin) and FOLFIRI doublets, in combination with bevacizumab. METHODS: TRIBE2 was an open-label, phase 3, randomised study of patients aged 18-75 years with an Eastern Cooperative Oncology Group (ECOG) performance status of 2, with unresectable, previously untreated metastatic colorectal cancer, recruited from 58 Italian oncology units. Patients were stratified according to centre, ECOG performance status, primary tumour location, and previous adjuvant chemotherapy. A randomisation system incorporating a minimisation algorithm was used to randomly assign patients (1:1) via a masked web-based allocation procedure to two different treatment strategies. In the control group, patients received first-line mFOLFOX6 (85 mg/m2 of intravenous oxaliplatin concurrently with 200 mg/m2 of leucovorin over 120 min; 400 mg/m2 intravenous bolus of fluorouracil; 2400 mg/m2 continuous infusion of fluorouracil for 48 h) plus bevacizumab (5 mg/kg intravenously over 30 min) followed by FOLFIRI (180 mg/m2 of intravenous irinotecan over 120 min concurrently with 200 mg/m2 of leucovorin; 400 mg/m2 intravenous bolus of fluorouracil; 2400 mg/m2 continuous infusion of fluorouracil for 48 h) plus bevacizumab after disease progression. In the experimental group, patients received FOLFOXIRI (165 mg/m2 of intravenous irinotecan over 60 min; 85 mg/m2 intravenous oxaliplatin concurrently with 200 mg/m2 of leucovorin over 120 min; 3200 mg/m2 continuous infusion of fluorouracil for 48 h) plus bevacizumab followed by the reintroduction of the same regimen after disease progression. Combination treatments were repeated every 14 days for up to eight cycles followed by fluorouracil and leucovorin (at the same dose administered at the last induction cycle) plus bevacizumab maintenance until disease progression, unacceptable adverse events, or consent withdrawal. Patients and investigators were not masked. The primary endpoint was progression-free survival 2, defined as the time from randomisation to disease progression on any treatment given after first disease progression, or death, analysed by intention to treat. Safety was assessed in patients who received at least one dose of their assigned treatment. Study recruitment is complete and follow-up is ongoing. This trial is registered with Clinicaltrials.gov, NCT02339116. FINDINGS: Between Feb 26, 2015, and May 15, 2017, 679 patients were randomly assigned and received treatment (340 in the control group and 339 in the experimental group). At data cut-off (July 30, 2019) median follow-up was 35·9 months (IQR 30·1-41·4). Median progression-free survival 2 was 19·2 months (95% CI 17·3-21·4) in the experimental group and 16·4 months (15·1-17·5) in the control group (hazard ratio [HR] 0·74, 95% CI 0·63-0·88; p=0·0005). During the first-line treatment, the most frequent of all-cause grade 3-4 events were diarrhoea (57 [17%] vs 18 [5%]), neutropenia (168 [50%] vs 71 [21%]), and arterial hypertension (25 [7%] vs 35 [10%]) in the experimental group compared with the control group. Serious adverse events occurred in 84 (25%) patients in the experimental group and in 56 (17%) patients in the control group. Eight treatment-related deaths were reported in the experimental group (two intestinal occlusions, two intestinal perforations, two sepsis, one myocardial infarction, and one bleeding) and four in the control group (two occlusions, one perforation, and one pulmonary embolism). After first disease progression, no substantial differences in the incidence of grade 3 or 4 adverse events were reported between the control and experimental groups, with the exception of neurotoxicity, which was only reported in the experimental group (six [5%] of 132 patients). Serious adverse events after disease progression occurred in 20 (15%) patients in the experimental group and 25 (12%) in the control group. Three treatment-related deaths after first disease progression were reported in the experimental group (two intestinal occlusions and one sepsis) and four in the control group (one intestinal occlusion, one intestinal perforation, one cerebrovascular event, and one sepsis). INTERPRETATION: Upfront FOLFOXIRI plus bevacizumab followed by the reintroduction of the same regimen after disease progression seems to be a preferable therapeutic strategy to sequential administration of chemotherapy doublets, in combination with bevacizumab, for patients with metastatic colorectal cancer selected according to the study criteria. FUNDING: The GONO Cooperative Group, the ARCO Foundation, and F Hoffmann-La Roche.

RESUMO

Importance: The addition of oxaliplatin to the standard 6-month fluorouracil-based adjuvant chemotherapy in stage II colorectal cancer has been reported to reduce the risk of relapse although it does not increase survival. The Three or Six Colon Adjuvant (TOSCA) trial compared 3 months with 6 months of adjuvant fluoropyrimidine and oxaliplatin-based chemotherapy in patients with stage III colon cancer. The utility remains unknown. Objective: To assess the noninferiority and toxic effects of 3 vs 6 months of FOLFOX (fluorouracil, leucovorin, and oxaliplatin) or CAPOX (capecitabine plus oxaliplatin) adjunct chemotherapy among patients with high-risk stage II resected colorectal cancer enrolled in the TOSCA trial. Design, Setting, and Participants: The TOSCA study was a noninferiority phase 3 randomized clinical trial conducted from June 2007 to March 2013 in 130 Italian centers. Included patients had resected colorectal cancer located 12 cm from the anal verge by endoscopy or above the peritoneal reflection at surgery. In this preplanned study assessing the per-protocol population, 5-year relapse-free survival was evaluated in 1254 patients with high-risk stage II resected colorectal cancer who had received adjuvant FOLFOX (fluorouracil, leucovorin, and oxaliplatin) or CAPOX (capecitabine plus oxaliplatin). Interventions: Patients were originally randomized (1:1) in the TOSCA trial to receive 3 months (experimental group) or 6 months (control) of standard doses of FOLFOX or CAPOX at the discretion of the treating physician. Main Outcome and Measures: A hazard ratio of at least 1.2 between the 3-month and 6-month chemotherapy groups was set to reject the null hypothesis of noninferiority. Results: Overall, 1254 patients (mean [SD] age, 62.4 [9.8] years; 565 women [45.1%]) with clinical high-risk stage II resected colorectal cancer were analyzed at a median follow-up of 62 months (interquartile range, 53-71) months. Of them, 301 patients (24.0%) had pT4N0M0 tumors, and the remaining 953 patients (76.0%) had high-risk pT3N0M0 tumors; 776 patients (61.9%) received FOLFOX and 478 (38.1%) received CAPOX. The 5-year relapse-free survival was 82.2% for the 3-month arm and 88.2% for the 6-month arm, with an estimated hazard ratio of 1.41 (95% CI, 1.05-1.89; P = .86 for noninferiority). For CAPOX, the 5-year relapse-free survival was similar in the 2 arms (difference, 0.76% favoring the 6-month arm; 95% CI, -6.28% to 7.80%), whereas for FOLFOX, the difference was pronounced: 8.56% in favor of the longer-duration arm (95% CI, 3.45%-13.67%). Nevertheless, the test for an interaction between duration and regimen was not statistically significant. Neurotoxicity was approximately 5 times lower in the shorter duration arm than in the longer duration arm. Conclusions and Relevance: In the 3-month arm, the treatment was significantly less toxic than in the 6-month arm. Noninferiority was not shown for 5-year relapse-free survival. However, a possible regimen effect was observed, suggesting that either 3 months of CAPOX or 6 months of FOLFOX therapy can be used whenever an oxaliplatin doublet is indicated for treatment of patients with stage II colorectal cancer.

RESUMO

Polymorphisms contribute to inter-individual differences and show a promising predictive role for chemotherapy-related toxicity in colon cancer (CC). TOSCA is a multicentre, randomized, non-inferiority, phase III study conducted in high-risk stage II/stage III CC patients treated with 6 vs 3 months of FOLFOX-4 or XELOX adjuvant chemotherapy. During this post-hoc analysis, 218 women and 294 men were genotyped for 17 polymorphisms: TYMS (rs34743033, rs2853542, rs11280056), MTHFR (rs1801133, rs1801131), ERCC1 (rs11615), XRCC1 (rs25487), XRCC3 (rs861539), XPD (rs1799793, rs13181), GSTP1 (rs1695), GSTT1/GSTM1 (deletion +/-), ABCC1 (rs2074087), and ABCC2 (rs3740066, rs1885301, rs4148386). The aim was to assess the interaction between these polymorphisms and sex, on safety in terms of time to grade ≥3 haematological (TTH), grade ≥3 gastrointestinal (TTG) and grade ≥2 neurological (TTN) toxicity. Interactions were detected on TTH for rs1801133 and rs1799793, on TTG for rs13181 and on TTN for rs11615. Rs1799793 GA genotype (p = 0.006) and A allele (p = 0.009) shortened TTH in men. In women, the rs11615 CC genotype worsened TTN (co-dominant model p = 0.008, recessive model p = 0.003) and rs13181 G allele improved the TTG (p = 0.039). Differences between the two sexes in genotype distribution of rs1885301 (p = 0.020) and rs4148386 (p = 0.005) were found. We highlight that polymorphisms could be sex-specific biomarkers. These results, however, need to be confirmed in additional series.

RESUMO

IMPORTANCE: Few studies are available on the role of maintenance strategies after induction treatment regimens based on anti-epidermal growth factor receptors, and the optimal regimen for an anti-epidermal growth factor receptors-based maintenance treatment in patients with RAS wild-type metastatic colorectal cancer is still to be defined. OBJECTIVE: To determine whether maintenance therapy with single-agent panitumumab was noninferior to panitumumab plus fluorouracil and leucovorin after a 4-month induction treatment regimen. DESIGN, SETTING, AND PARTICIPANTS: This open-label, randomized phase 2 noninferiority trial was conducted from July 7, 2015, through October 27, 2017, at multiple Italian centers. Patients with RAS wild-type, unresectable metastatic colorectal adenocarcinoma who had not received previous treatment for metastatic disease were eligible. Induction therapy consisted of panitumumab plus FOLFOX-4 (panitumumab, 6 mg/kg, oxaliplatin, 85 mg/m2 at day 1, leucovorin calcium, 200 mg/m2, and fluorouracil, 400-mg/m2 bolus, followed by 600-mg/m2 continuous 24-hour infusion at days 1 and 2, every 2 weeks). Cutoff date for analyses was July 30, 2018. INTERVENTIONS: Patients were randomized (1:1) to first-line panitumumab plus FOLFOX-4 for 8 cycles followed by maintenance therapy with panitumumab plus fluorouracil-leucovorin (arm A) or panitumumab (arm B) until progressive disease, unacceptable toxic effects, or consent withdrawal. The minimization method was used to stratify randomization by previous adjuvant treatment and number of metastatic sites. MAIN OUTCOMES AND MEASURES: The prespecified primary end point was 10-month progression-free survival (PFS) analyzed on an intention-to-treat basis with a noninferiority margin of 1.515 for the upper limit of the 1-sided 90% CI of the hazard ratio (HR) of arm B vs A. RESULTS: Overall, 229 patients (153 male [66.8%]; median age, 64 years [interquartile range (IQR), 56-70 years]) were randomly assigned to arm A (n = 117) or arm B (n = 112). At a median follow-up of 18.0 months (IQR, 13.1-23.3 months]), a total of 169 disease progression or death events occurred. Arm B was inferior (upper limit of 1-sided 90% CI of the HR, 1.857). Ten-month PFS was 59.9% (95% CI, 51.5%-69.8%) in arm A vs 49.0% (95% CI, 40.5%-59.4%) in arm B (HR, 1.51; 95% CI, 1.11-2.07; P = .01). During maintenance, arm A had a higher incidence of grade 3 or greater treatment-related adverse events (36 [42.4%] vs 16 [20.3%]) and panitumumab-related adverse events (27 [31.8%] vs 13 [16.4%]), compared with arm B. CONCLUSIONS AND RELEVANCE: In patients with RAS wild-type metastatic colorectal cancer, maintenance therapy with single-agent panitumumab was inferior in terms of PFS compared with panitumumab plus fluorouracil-leucovorin, which slightly increased the treatment toxic effects.

PURPOSE: The international guidelines recommend the use of supplemental parenteral nutrition (SPN) in cancer patients when they are malnourished and hypophagic and where enteral nutrition is not feasible. However, there are limited data on the short-term effects of SPN in this patient population. METHODS: The aim of this bicentric single-arm clinical trial (NCT02828150) was to evaluate the effects of early 7-day SPN on bioimpedance vectorial analysis (BIVA)-derived body composition, handgrip strength (HG), and serum prealbumin (PAB) in 131 hypophagic, hospitalized cancer patients at nutritional risk, with contraindications for enteral nutrition. RESULTS: One hundred eighteen patients (90.1%) completed the 7-day SPN support regimen and 102 of them (86.4%) were in advanced disease stage. SPN induced a significant improvement of phase angle (PhA, + 0.25 [95% CI 0.11, 0.39]; p = 0.001), standardized phase angle (SPA, + 0.33 [95% CI 0.13, 0.53]; p = 0.002), HG (+ 2.1 kg -95% CI 1.30, 2.81]; p < 0.001), and PAB (+ 3.8 mg/dL [95% CI 2.1, 5.6]; p < 0.001). In multivariable analysis, the effects on BIVA parameters were more pronounced in patients (N = 90, 76.3%) in whom estimated protein and calorie requirements were both satisfied (adjusted difference: PhA, + 0.39 [95% CI 0.04, 0.73]; p = 0.030; SPA, + 0.62 [95% CI 0.16, 1.09]; p = 0.009). No significant changes in hydration status were detected and no severe metabolic or other complications occurred. CONCLUSIONS: Early 7-day SPN resulted in improved body composition, HG and PAB levels in hypophagic, and hospitalized cancer patients at nutritional risk in the absence of any relevant clinical complications. Further trials, aimed at verifying the efficacy of this early nutritional intervention on mid- and long-term primary clinical endpoints in specific cancer types, are warranted.

RESUMO

INTRODUCTION: Although sorafenib is the upfront standard of care for advanced hepatocellular carcinoma (HCC), molecular predictors of efficacy have not been identified yet. In the ALICE-1 study, rs2010963 of VEGF-A and VEGF-C proved to be independent predictive factors for progression-free survival (PFS) and overall survival (OS) in multivariate analysis. The ALICE-1 study results were confirmed in the ALICE-2 study, in which VEGF and VEGFR SNPs were analyzed. In the ePHAS study we analyzed the SNPs of eNOS. In univariate analysis, patients homozygous for an eNOS haplotype (HT1: T-4b at eNOS-786/eNOS VNTR) had significantly shorter median PFS and OS than those with other haplotypes. These data were confirmed in the validation set. METHODS: This nonpharmacological, interventional, prospective multicenter study aims to determine whether eNOS, HIF-1, VEGF, Ang2 and VEGFR polymorphisms play a role in predicting the objective response rate, PFS, and OS of advanced HCC patients treated with sorafenib. The study will involve 160 advanced HCC patients with Child-Pugh class A disease. The primary aim is to validate the prognostic or predictive roles of eNOS, Ang2, HIF-1, VEGF and VEGFR polymorphisms in relation to the clinical outcome (PFS) of HCC patients treated with sorafenib. CONCLUSIONS: Overall, our data may suggest that polymorphism analysis of the VEGF, VEGFR-2, HIF and eNOS genes can identify HCC patients who are more likely to benefit from sorafenib.

RESUMO

Purpose Given the cumulative neurotoxicity associated with oxaliplatin, a shorter duration of adjuvant therapy, if equally efficacious, would be advantageous for patients and health-care systems. Methods The Three or Six Colon Adjuvant trial is an open-label, phase III, multicenter, noninferiority trial randomizing patients with high-risk stage II or stage III colon cancer to receive 3 months or 6 months of FOLFOX (fluorouracil, leucovorin, and oxaliplatin) or CAPOX (capecitabine plus oxaliplatin). Primary end-point is relapse-free survival. Results 3,759 patients were accrued from 130 Italian sites, 64% receiving FOLFOX and 36% CAPOX. Two-thirds were stage III. The median time of follow up was 62 months and 772 relapses or deaths have been observed. The hazard ratio (HR) of the 3 months versus 6 months for relapse/death was 1.14 (95% CI, 0.99 to 1.32; P [for noninferiority] = .514) and the CI crossed the noninferiority limit of 1.20. However, the absolute difference in 3-year RFS was 1.9% (95% CI, -0.7% to 4.4%). Counter-intuitively, while the RFS curves were similar for stage III (HR, 1.07; 95% CI, 0.91 to 1.26) and for CAPOX treated patients (HR, 0.98; 95% CI, 0.77 to 1.26), they were not for stage II and for FOLFOX treated patients, with HR of 1.41 (95% CI, 1.05 to 1.89) and 1.23 (95% CI, 1.03 to 1.46), respectively, favoring the 6 months of treatment. Conclusion The Three or Six Colon Adjuvant trial failed to formally show noninferiority of 3 versus 6 months of treatment to the predefined margin of 20% relative increase. The results depended on the adjuvant regimen and risk. For CAPOX, 3 months were as good as 6 months; for FOLFOX, 6 months added extra benefit. Counter-intuitively, the low-risk patients benefitted more than the high-risk population from the 6-month duration. The choice of regimen and duration should depend on patient characteristics and be balanced against the extra toxicity of longer therapy.

RESUMO

OBJECTIVES: The attitude toward malnutrition varies considerably among oncologists and many malnourished cancer patients receive inadequate nutritional support. The aim of this brief report was to report the results of the exploratory national survey conducted by the Italian Society of Medical Oncology (AIOM) and the Italian Society of Artificial Nutrition and Metabolism (SINPE) before publication of a consensus document aimed at evaluating current attitudes toward malnutrition and management of nutrition, among Italian medical oncologists. METHODS: Between January and July 2015, the AIOM and the SINPE conducted a national web-based exploratory survey to investigate the attitude of oncologists toward malnutrition, and the management of nutritional support, before publication of an intersociety consensus document. RESULTS: Of the 2375 AIOM members, 135 (5.7%) participated in the survey, with a satisfactory distribution across all Italian regions. Nutritional assessment and support were routinely integrated into patient care for 38 (28%) responders. According to 66 (49%) participants, nutritional assessment was carried out only at the patients' request (n = 62), or not at all (n = 4). Availability of clinical nutritionists was reported by 88 (65%) participants. For 131 responders (97%), nutritional status was decisive (n = 63) or often crucial (n = 68) in assessing whether anticancer treatment was practicable or would be tolerated. CONCLUSIONS: The low response rate may reflect the lack of awareness and consideration of nutritional issues among Italian oncologists. Although malnutrition and nutritional support seemed to be perceived by the responders as relevant factors for the efficacy of oncologic treatments, it seems that nutritional care practices may well be inappropriate. The lack of collaboration between oncologists and clinical nutritionists may be the first obstacle to overcome. Educational intersociety initiatives aimed at improving nutritional support management for cancer patients in Italy appear urgently needed.

RESUMO

BACKGROUND & AIMS: No established therapies for patients with hepatocellular carcinoma (HCC) and progression on first-line sorafenib treatment currently exist. This phase I/II trial investigated safety, pharmacokinetics and potential biomarkers of the histone deacetylase inhibitor resminostat and a combination therapy with resminostat and sorafenib. METHODS: Patients with HCC and radiologically confirmed progression on sorafenib were treated in an exploratory, multi-center, open-label, uncontrolled, non-randomized, parallel group phase I/II study. In the combination group (n=38) four dose levels ranged from daily 200 to 600mg resminostat plus 400 to 800mg sorafenib. The monotherapy group (n=19) received 600mg resminostat. RESULTS: 57 patients received treatment. Most common adverse events were gastrointestinal disorders, thrombocytopenia and fatigue. Median maximal histone deacetylase inhibition and highest increase in H4-acetylation matched Tmax of resminostat. Sorafenib or the Child-Pugh score did not affect typical pharmacokinetics characteristics of resminostat. Efficacy assessment as progression-free survival-rate after 6 treatment cycles (12weeks, primary endpoint) was 12.5% for resminostat and 62.5% for resminostat plus sorafenib. Median time to progression and overall survival were 1.8 and 4.1months for resminostat and 6.5 and 8.0months for the combination, respectively. Zinc finger protein 64 (ZFP64) baseline expression in blood cells was found to correlate with overall survival. CONCLUSIONS: The combination of sorafenib and resminostat in HCC patients was safe and showed early signs of efficacy. Sorafenib did not alter the pharmacokinetic profile of resminostat or its histone deacetylase inhibitory activity in vivo. A prognostic and potentially predictive role of ZFP64 for treatment with resminostat should be further investigated in HCC and possibly other cancer indications. LAY SUMMARY: No established therapy for patients with advanced hepatocellular carcinoma and progression under first-line systemic treatment with sorafenib currently exists. Epigenetic modulation by inhibition of histone deacetylases might be able to overcome therapy resistance. This exploratory phase I/II clinical study in patients with radiologically confirmed progression under first-line treatment with sorafenib investigated the histone deacetylases inhibitor resminostat as single agent or in combination with continued application of sorafenib. CLINICAL TRIAL REGISTRATION: The clinical trial has been registered at www.clinicaltrials.gov as NCT00943449.

RESUMO

We investigated 17 polymorphisms in 11 genes (TS, MTHFR, ERCC1, XRCC1, XRCC3, XPD, GSTT1, GSTP1, GSTM1, ABCC1, ABCC2) for their association with the toxicity of fluoropyrimidines and oxaliplatin in colorectal cancer patients enrolled in a prospective randomized trial of adjuvant chemotherapy. The TOSCA Italian adjuvant trial was conducted in high-risk stage II-III colorectal cancer patients treated with 6 or 3 months of either FOLFOX-4 or XELOX adjuvant chemotherapy. In the concomitant ancillary pharmacogenetic study, the primary endpoint was the association of polymorphisms with grade 3-4 CTCAE toxicity events (grade 2-4 for neurotoxicity). In 517 analyzed patients, grade ≥ 3 neutropenia and grade ≥ 2 neurotoxicity events occurred in 150 (29%) and in 132 patients (24.8%), respectively. Diarrhea grade ≥ 3 events occurred in 34 (6.5%) patients. None of the studied polymorphisms showed clinically relevant association with toxicity. Hopefully, genome-wide association studies will identify new and more promising genetic variants to be tested in future studies.

RESUMO

BACKGROUND: The RAF-MEK-ERK pathway is commonly activated in pancreatic cancer because of a high frequency of KRAS-BRAF mutations. A phase II randomized trial was designed to investigate the activity of sorafenib in combination with chemotherapy in advanced pancreatic cancer. METHODS: Locally advanced or metastatic pancreatic adenocarcinoma patients were randomized in a 1:1 ratio to receive cisplatin plus gemcitabine with sorafenib 400mg bid (arm A) or without sorafenib (arm B). RESULTS: One hundred and fourteen patients were enrolled; of these, 43 (74.6%) patients progressed in arm A and 44 (82.4%) in arm B. Median progression-free survival was 4.3 months (95% CI: 2.7-6.5) and 4.5 months (95% CI: 2.5-5.2), respectively (HR=0.92; 95% CI: 0.62-1.35). Median overall survival was 7.5 (95% CI: 5.6-9.7) and 8.3 months (95% CI: 6.2-8.7), respectively (HR=0.95; 95% CI: 0.62-1.48). Response rates were 3.4% in arm A and 3.6% in arm B. CONCLUSIONS: Sorafenib does not significantly enhance activity of chemotherapy in advanced pancreatic cancer patients, and therefore should not be assessed in phase III trials.

RESUMO

BACKGROUND: Bevacizumab has provided encouraging results in relapsed glioblastoma multiforme (GBM). Pre-clinical and clinical investigations also showed that continuous low-dose temozolomide has some antiangiogenic activity. Based on this evidence, a phase II trial was designed to investigate an oral regimen of sorafenib, an oral multikinase inhibitor, and metronomic temozolomide for relapsed GBM. PATIENTS AND METHODS: Forty-three patients (median age=60.0 years) naive for antiangiogenic agents received 400 mg sorafenib twice daily plus TMZ 40 mg/m(2)/day until disease progression. RESULTS: Toxicity, mostly grade 1-2, was manageable. Grade 3-4 toxicities were hand-foot syndrome (n=4), hypertension (n=2), and fatigue (n=3). Five patients (12%) achieved partial response, 18 (43%) stable disease, 20 (48%) showed progression. The median time-to-progression was 3.2 months, 6-month progression-free survival was 26%, and median overall survival was 7.4 months. CONCLUSION: This combination of sorafenib and temozolomide was feasible and safe, showing some activity in patients with relapsed GBM.

RESUMO

Treatment with angiogenesis inhibitors is becoming a cornerstone of modern anticancer therapy. Hypertension (HTN) is a common adverse event during antiangiogenic treatment and might represent a cancer biomarker in patients with recurrent glioblastoma treated with angiogenesis inhibitors. In a retrospective study, we analyzed 53 patients with recurrent glioblastoma treated with antiangiogenic drugs. Thirty patients were treated with sorafenib and 23 patients were treated with bevacizumab. All patients underwent brain gadolinium-enhanced MRI assessments according to the Radiologic Assessment in Neuro-Oncology criteria every 2 months or when clinically indicated. Blood pressure was measured before and during the treatment. We investigated whether treatment-related HTN may be associated with outcome in patients treated with antiangiogenic drugs. After 2 months of treatment, 24 patients (45%) achieved disease control: stable disease (17 patients) or a partial response (seven patients). The median overall survival from the start of antiangiogenic treatment was 7.3 months [95% confidence interval (CI) 6.02-8.5]; the median progression-free survival (PFS) was 2.7 months (95% CI 1.5-3.5); and the 6-month PFS was 32%. Twenty patients (38%) developed grades 2-3 HTN within 2 months of treatment. A significant association was found between HTN and disease control rate, and HTN and 6-month PFS; no significant association was found between HTN and the median PFS. According to univariate and multivariate analyses, HTN was related to a longer survival from antiangiogenic drug administration: 9.8 versus 4.8 months (P=0.001; hazard ratio=3.5, 95% CI 1.6-7.6). Our data indicate that HTN may be an effective biomarker in patients with recurrent glioblastoma treated with antiangiogenic drugs; in particular, it may be associated with a favorable effect on disease control, 6-month PFS, and the median overall survival.
