RESUMO
BACKGROUND: EOX (epirubicin, oxaliplatin, and capecitabine) is one of the standard regimens for metastatic or locally advanced gastric cancer (GC). A new combination based on fractional docetaxel (low-TOX) has been developed in an attempt to increase the efficacy of EOX and reduce the heavy toxicity of classical docetaxel regimens. METHODS: Overall, 169 previously untreated GC patients were randomized between EOX (arm A) and low-TOX (arm B). The primary endpoint was progression-free survival (PFS), while secondary ones were overall survival (OS), overall response rate (ORR), disease control rate (DCR), and tolerability. The study was designed to detect a 35% (80% power at a two-sided 5% significance level) PFS increase with low-TOX and an interim analysis for futility was planned after the first 127 events. RESULTS: At the cut-off date of interim analysis, median PFS was 6.3 months [95% confidence interval (CI) 5.0-8.1] in arm A vs 6.3 months (95% CI 5.0-7.8) in arm B, without statistical difference. OS was comparable in the two arms: 12.4 in arm A (95% CI 9.1-19.2) vs 11.5 months in arm B (95% CI 8.6-15.0). ORR was 33% and 24%, while DCR was 68% and 67%, respectively. Treatment modification (91% vs 78%, P = 0.017) and number of patients with CTC grade ≥ 3 adverse events (42 vs 35) were higher in arm B. CONCLUSIONS: A triplet regimen based on the fractional dose of docetaxel achieves no improvement over EOX which remains a potential standard treatment in many patients with inoperable, locally advanced or metastatic GC.

BACKGROUND: Since 2004, a regimen of 6 months of treatment with oxaliplatin plus a fluoropyrimidine has been standard adjuvant therapy in patients with stage III colon cancer. However, since oxaliplatin is associated with cumulative neurotoxicity, a shorter duration of therapy could spare toxic effects and health expenditures. METHODS: We performed a prospective, preplanned, pooled analysis of six randomized, phase 3 trials that were conducted concurrently to evaluate the noninferiority of adjuvant therapy with either FOLFOX (fluorouracil, leucovorin, and oxaliplatin) or CAPOX (capecitabine and oxaliplatin) administered for 3 months, as compared with 6 months. The primary end point was the rate of disease-free survival at 3 years. Noninferiority of 3 months versus 6 months of therapy could be claimed if the upper limit of the two-sided 95% confidence interval of the hazard ratio did not exceed 1.12. RESULTS: After 3263 events of disease recurrence or death had been reported in 12,834 patients, the noninferiority of 3 months of treatment versus 6 months was not confirmed in the overall study population (hazard ratio, 1.07; 95% confidence interval [CI], 1.00 to 1.15). Noninferiority of the shorter regimen was seen for CAPOX (hazard ratio, 0.95; 95% CI, 0.85 to 1.06) but not for FOLFOX (hazard ratio, 1.16; 95% CI, 1.06 to 1.26). In an exploratory analysis of the combined regimens, among the patients with T1, T2, or T3 and N1 cancers, 3 months of therapy was noninferior to 6 months, with a 3-year rate of disease-free survival of 83.1% and 83.3%, respectively (hazard ratio, 1.01; 95% CI, 0.90 to 1.12). Among patients with cancers that were classified as T4, N2, or both, the disease-free survival rate for a 6-month duration of therapy was superior to that for a 3-month duration (64.4% vs. 62.7%) for the combined treatments (hazard ratio, 1.12; 95% CI, 1.03 to 1.23; P=0.01 for superiority). CONCLUSIONS: Among patients with stage III colon cancer receiving adjuvant therapy with FOLFOX or CAPOX, noninferiority of 3 months of therapy, as compared with 6 months, was not confirmed in the overall population. However, in patients treated with CAPOX, 3 months of therapy was as effective as 6 months, particularly in the lower-risk subgroup. (Funded by the National Cancer Institute and others.).

BACKGROUND: A prospective, pooled analysis of six randomised phase 3 trials was done to investigate disease-free survival regarding non-inferiority of 3 months versus 6 months of adjuvant chemotherapy for patients with stage III colon cancer; non-inferiority was not shown. Here, we report the final overall survival results. METHODS: In this prospective, pooled analysis of six randomised phase 3 trials, we included patients with stage III colon cancer aged at least 18 years with an Eastern Cooperative Oncology Group performance status of 0-1 recruited between June 20, 2007, and Dec 31, 2015, across 12 countries in the CALGB/SWOG 80702, IDEA France, SCOT, ACHIEVE, TOSCA, and HORG trials, who started any treatment (modified intention-to-treat). Patients in all trials were randomly assigned to 3 months or 6 months of adjuvant fluorouracil, leucovorin, and oxaliplatin (FOLFOX) every 2 weeks or capecitabine and oxaliplatin (CAPOX) in different doses and methods every 3 weeks, at the treating physician's discretion. The primary endpoint was disease-free survival (time to relapse, secondary colorectal primary tumour, or death due to all causes), and overall survival (time to death due to all causes) was the prespecified secondary endpoint. The non-inferiority margin for overall survival was set as a hazard ratio (HR) of 1·11. Pre-planned subgroup analyses included regimen and risk group. Non-inferiority was declared if the one-sided false discovery rate adjusted (FDRadj) p value was less than 0·025. FINDINGS: With median follow-up of 72·3 months (IQR 72·2-72·5), 2584 deaths among 12â835 patients were observed. 5064 (39·5%) patients received CAPOX and 7771 (60·5%) received FOLFOX. 5-year overall survival was 82·4% (95% CI 81·4-83·3) with 3 months of therapy and 82·8% (81·8-83·8) with 6 months of therapy (HR 1·02 [95% CI 0·95-1·11]; non-inferiority FDRadj p=0·058). For patients treated with CAPOX, 5-year overall survival was 82·1% (80·5-83·6) versus 81·2% (79·2-82·9; HR 0·96 [0·85-1·08]); non-inferiority FDRadj p=0·033), and for patients treated with FOLFOX 5-year overall survival was 82·6% (81·3-83·8) and 83·8% (82·6-85·0; HR 1·07 [0·97-1·18]; non-inferiority FDRadj p=0·34). Updated disease-free survival results confirmed previous findings (HR 1·08 [95% CI 1·02-1·15]; non-inferiority FDRadj p=0·25). Data on adverse events were not further recorded. INTERPRETATION: Non-inferiority of 3 months versus 6 months of adjuvant chemotherapy for patients with stage III colon cancer was not confirmed in terms of overall survival, but the absolute 0·4% difference in 5-year overall survival should be placed in clinical context. Overall survival results support the use of 3 months of adjuvant CAPOX for most patients with stage III colon cancer. This conclusion is strengthened by the substantial reduction of toxicities, inconveniencies, and cost associated with a shorter treatment duration. FUNDING: US National Cancer Institute.

BACKGROUND: Although American Society of Clinical Oncology and European Society for Medical Oncology guidelines have identified the negative prognostic factors that clinicians have to consider when treating their patients with stage II colon cancer (CC), the role of histological subtype is controversial. SUBJECTS, MATERIALS, AND METHODS: The randomized, multicenter, phase III TOSCA trial compared 3 versus 6 months of fluoropyrimidine-oxaliplatin adjuvant chemotherapy in 3,759 patients with high-risk stage II or stage III CC. The objective of this substudy was to evaluate the influence of histological subtypes on the impact of the treatment duration of adjuvant chemotherapy in terms of relapse-free survival (RFS) and overall survival (OS) in 85 mucinous adenocarcinoma (MUC) and 389 nonmucinous adenocarcinoma (NMUC) patients with high-risk stage II, grade 3 CC. RESULTS: A significant interaction between treatment duration and histology was observed in both RFS (p = .027) and OS (p = .017). In the subgroup of patients with MUC, worse RFS (adjusted hazard ratio [HR], 3.95; 95% confidence interval [CI], 1.03-15.17; p = .045) and OS (HR, 9.56; 95% CI, 1.14-79.98; p = .037) were detected for patients treated in the 3-month arm. No statistically significant differences were found in the subgroup of patients with NMUC. CONCLUSION: Patients with MUC, grade 3, stage II CC require special attention and may need 6 months of oxaliplatin-based chemotherapy. Larger studies are required to assess the combined use of histology and other prognostic/predictive factors to define the administration of chemotherapy in patients with stage II CC and to improve their prognosis. IMPLICATIONS FOR PRACTICE: Although ASCO and ESMO guidelines define the prognostic factors for patients with stage II colon cancer to establish the use of adjuvant chemotherapy, the influence of histological subtypes is controversial in this population. This study underscores that patients with grade 3 mucinous adenocarcinomas may need adjuvant chemotherapy with oxaliplatin and fluoropyrimidines for a duration of 6 months rather than 3 months.

In cancer patients, hypercoagulability is a common finding. It has been associated with an increased risk of venous thromboembolism, but also to tumor proliferation and progression. In this prospective study of a large cohort of breast cancer patients, we aimed to evaluate whether pre-chemotherapy abnormalities in hemostatic biomarkers levels: (i) are associated with breast cancer-specific clinico-pathological features; and (ii) can predict for disease recurrence. D-dimer, fibrinogen, prothrombin fragment 1+2, and FVIIa/antithrombin levels were measured in 701 early-stage resected breast cancer patients candidate to adjuvant chemotherapy and prospectively enrolled in the HYPERCAN study. Significant prognostic parameters for disease recurrence were identified by Cox regression multivariate analysis and used for generating a risk assessment model. Pre-chemotherapy D-dimer, fibrinogen, and pro-thrombin fragment 1+2 levels were significantly associated with tumor size and lymph node metastasis. After 3.4 years of follow up, 71 patients experienced a recurrence. Cox multivariate analysis identified prothrombin fragment 1+2, tumor size, and Luminal B HER2-negative or triple negative molecular subtypes as independent risk factors for disease recurrence. Based on these variables, we generated a risk assessment model that significantly differentiated patients at low- and high-risk of recurrence (cumulative incidence: 6.2 vs 20.7%; Hazard Ratio=3.5; P<0.001). Our prospective clinical and laboratory data from the HYPERCAN study were crucial for generating a scoring model for assessing risk of disease recurrence in resected breast cancer patients, candidate to systemic chemotherapy. This finding stimulates future investigations addressing the role of plasma prothrombin fragment 1+2 in the management of breast cancer patients to provide the rationale for new therapeutic strategies. (The HYPERCAN study is registered at clinicaltrials.gov identifier 02622815).

BACKGROUND: Type 2 diabetes mellitus (T2DM) is associated with increased risk of colon cancer (CC), whereas metformin use seems to be protective. However, the impact of metformin use on the risk of death or disease recurrence after radical surgery for CC remains uncertain. MATERIALS AND METHODS: This is a substudy conducted in patients with high-risk stage II or stage III CC randomized in the TOSCA trial, which compared 3 versus 6 months of fluoropyrimidine-oxaliplatin adjuvant chemotherapy. Objective of the study was to investigate the impact of metformin exposure during adjuvant chemotherapy on overall survival (OS) and relapse-free survival (RFS). We also evaluated the impact of T2DM or metformin dosage on clinical outcomes. RESULTS: Out of 3,759 patients enrolled in the TOSCA trial, 133 patients with diabetes (9.2%) and 1,319 without diabetes (90.8%) were recruited in this study. After excluding 13 patients with diabetes without information on metformin exposure, 76 patients with T2DM (63.3%) were defined as metformin users and 44 (36.7%) as metformin nonusers. After a median follow-up of 60.4 months, 26 (21.7%) patients relapsed and 16 (13.3%) died. Metformin use was neither associated with OS (adjusted hazard ratio [HR], 1.51; 95% confidence interval [CI], 0.48-4.77; p = .4781) nor with RFS (HR, 1.56; 95% CI, 0.69-3.54; p = .2881). Similarly, we found no association between T2DM or metformin dosage and OS or RFS. CONCLUSIONS: Metformin use and T2DM did not impact on OS or RFS in patients with resected CC treated with adjuvant fluoropyrimidine-oxaliplatin chemotherapy. Larger studies and longer follow-up are required to clarify the potential efficacy of metformin in improving the prognosis of patients with CC. IMPLICATIONS FOR PRACTICE: The role of the antidiabetic drug metformin in colon cancer prevention and treatment is highly debated. While low-dose metformin reduced the incidence of colorectal adenomas in two prospective studies, its effect in patients with already established colon cancer remains unclear. In this study, the potential impact of metformin on the survival of resected colon cancer patients who received adjuvant chemotherapy was investigated in the context of the TOSCA study. We did not find any association between metformin use or dosages and patient survival. Prospective studies are required to draw definitive conclusions about metformin impact on colon cancer recurrence and survival.

Variations in the reporting of potentially confounding variables in studies investigating systemic treatments for unresectable pancreatic cancer pose challenges in drawing accurate comparisons between findings. In this Review, we establish the first international consensus on mandatory baseline and prognostic characteristics in future trials for the treatment of unresectable pancreatic cancer. We did a systematic literature search to find phase 3 trials investigating first-line systemic treatment for locally advanced or metastatic pancreatic cancer to identify baseline characteristics and prognostic variables. We created a structured overview showing the reporting frequencies of baseline characteristics and the prognostic relevance of identified variables. We used a modified Delphi panel of two rounds involving an international panel of 23 leading medical oncologists in the field of pancreatic cancer to develop a consensus on the various variables identified. In total, 39 randomised controlled trials that had data on 15â863 patients were included, of which 32 baseline characteristics and 26 prognostic characteristics were identified. After two consensus rounds, 23 baseline characteristics and 12 prognostic characteristics were designated as mandatory for future pancreatic cancer trials. The COnsensus statement on Mandatory Measurements in unresectable PAncreatic Cancer Trials (COMM-PACT) identifies a mandatory set of baseline and prognostic characteristics to allow adequate comparison of outcomes between pancreatic cancer studies.

BACKGROUND: Previous findings suggested that bevacizumab might be able to improve response rate (RR) in colorectal cancer patients with high lactic dehydrogenase (LDH) basal levels. METHODS: We conducted a phase II trial to prospectively ascertain whether bevacizumab in combination with FOLFIRI could have an improved clinical activity in patients with high LDH serum levels. Primary end point of the study was RR; secondary end points were median overall survival and median progression-free survival (mPFS). RESULTS: A total of 81 patients were enrolled. No difference in terms of ORR (39% vs 31% for low vs high LDH level stratum, P=0.78) and mPFS (14.16 vs 10.29 months, HR: 1.07, 95% CI: 0.51-2.24, P=0.83) between the strata was observed, whereas overall survival (OS) was significantly longer for patients with low LDH (24.85 vs 15.14 months, HR: 4.08, 95% CI: 1.14-14.61, P=0.0004). In a not-pre-planned exploratory analysis using different cut-off ranges for LDH, we observed RR up to 70%, with no improvement in progression-free survival or OS. CONCLUSIONS: The CENTRAL trial failed to demonstrate that high LDH levels were related to a significantly improved RR in patients receiving first-line FOLFIRI and bevacizumab. The LDH serum levels should then no further be investigated as a predictive factor in this setting.

We sought to develop criteria for ERBB2-positivity (HER2) in colorectal cancer to ensure accurate identification of ERBB2-amplified metastatic colorectal cancer patients suitable for enrollment in a phase II trial of ERBB2-targeted therapy (HERACLES trial). A two-step approach was used. In step 1, a consensus panel of pathologists adapted existing protocols for use in colorectal cancer to test ERBB2 expression and amplification. Collegial revision of an archival test cohort of colorectal cancer samples led to specific recommendations for adapting current breast and gastric cancer criteria for scoring ERBB2 in colorectal cancer. In step 2, from September 2012 to January 2015, colorectal-specific ERBB2 testing protocols and ERBB2 scoring criteria were used to centrally screen for ERBB2-positive KRAS wild-type colorectal cancer patients to be enrolled in the HERACLES trial (clinical validation cohort). In both archival test (N=256) and clinical validation (N=830) cohorts, a clinically sizeable 5% fraction of KRAS wild-type colorectal cancer patients was found to be ERBB2-positive according to the colorectal cancer-specific ERBB2 scoring criteria. ERBB2-positive tumors showed ERBB2 immunostaining consisting of intense membranous ERBB2 protein expression, corresponding to homogenous ERBB2 amplification, in >50% of cells. None of the immunohistochemistry 0 or 1+ cases was amplified. Concordance between SISH and FISH was 100%. In conclusion, we propose specific criteria for defining ERBB2-positivity in colorectal cancer (HERACLES Diagnostic Criteria). In a phase II trial of trastuzumab and lapatinib in a cetuximab-resistant population, HERACLES Diagnostic Criteria shaped the selection of patients and defined ERBB2 as a predictive marker for response to ERBB2-targeted therapy in metastatic colorectal cancer.

OBJECTIVES: Patients with metastatic renal cell carcinoma (mRCC) received sunitinib in a global expanded-access program (EAP). Here, we report the efficacy and safety results for the EAP subpopulation in Italy. METHODS: Patients ≥18 years old with previously treated or treatment-naïve mRCC received oral sunitinib 50 mg/day on a 4-weeks-on/2-weeks-off schedule. Tumor measurements were scheduled per local practice (using Response Evaluation Criteria in Solid Tumors). Safety was regularly assessed. RESULTS: A total of 521 patients participated, including 40% aged ≥65 years, 11% with an Eastern Cooperative Oncology Group performance status ≥2, 14% with non-clear cell RCC, and 11% with brain metastases. The median treatment duration and posttreatment follow-up were 7.4 and 12.3 months, respectively. The objective response rate was 12%, and the median progression-free and overall survival was 9.1 and 27.2 months, respectively. 514 patients (99%) discontinued treatment; reasons included death (17%), nonresponse (46%), or adverse events (AEs; 13%). The most common any-grade treatment-related AEs were asthenia (44%, plus 15% reporting fatigue), thrombocytopenia and stomatitis (both 37%), diarrhea (36%), mucosal inflammation (29%), hypertension (26%), and dysgeusia (25%). The most common grade 3/4 treatment-related AEs were thrombocytopenia (10%), asthenia (9%, plus 3% reporting fatigue), neutropenia, stomatitis (both 6%), and hypertension (5%). CONCLUSION: In a large population of Italian mRCC patients, sunitinib had a manageable safety profile and encouraging efficacy.

Pancreatic ductal adenocarcinoma (PDAC), which accounts for more than 90% of all pancreatic tumours, is a devastating malignancy with an extremely poor prognosis, as shown by a 1-year survival rate of around 18% for all stages of the disease. The low survival rates associated with PDAC primarily reflect the fact that tumours progress rapidly with few specific symptoms and are thus at an advanced stage at diagnosis in most patients. As a result, there is an urgent need to develop accurate markers of pre-invasive pancreatic neoplasms in order to facilitate prediction of cancer risk and to help diagnose the disease at an earlier stage. However, screening for early diagnosis of prostate cancer remains challenging and identifying a highly accurate, low-cost screening test for early PDAC for use in clinical practice remains an important unmet need. More effective therapies are also crucial in PDAC, since progress in identifying novel therapies has been hampered by the genetic complexity of the disease and treatment remains a major challenge. Presently, the greatest step towards improved treatment efficacy has been made in the field of palliative chemotherapy by introducing FOLFIRINOX (folinic acid, 5-fluorouracil, irinotecan and oxaliplatin) and gemcitabine/nab-paclitaxel. Strategies designed to raise the profile of PDAC in research and clinical practice are a further requirement in order to ensure the best treatment for patients. This article proposes a number of approaches that may help to accelerate progress in treating patients with PDAC, which, in turn, may be expected to improve the quality of life and survival for those suffering from this devastating disease.

BACKGROUND & AIMS: Sorafenib is the standard of care in advanced hepatocellular carcinoma (HCC), however no criteria have been established to select patients likely to benefit from this therapy. In this study, we evaluated the predictive role of microRNAs (miRNAs) in this setting of patients. METHODS: We profiled 522 miRNA in a series of 26 HCC patients treated with sorafenib (training set) and validated the results in an independent series of 58 patients (validation set). Formalin-fixed paraffin-embedded tumour and cirrhotic liver biopsies were used for RNA extraction and miRNAs profiling with TaqMan Arrays technology. Statistical analyses were used to correlate miRNA levels with clinical outcome, including time to progression (TTP), progression free (PFS), and overall survival. Cell viability and cell motility of HuH-7 or HepG2 HCC cells were tested in vitro after transfection with specific miRNA precursor, inhibitor or controls and sorafenib treatment. RESULTS: Six miRNAs were significantly associated with clinical variables in the training set and only miR-425-3p could be further validated. Higher levels of miR-425-3p were associated with longer TTP and PFS (P = 0.0008; HR = 0.4; 95% CI = 0.2-0.7 and P = 0.007; HR = 0.5; 95% CI = 0.3-0.9 respectively). Multivariate analysis confirmed the predictive significance of miR-425-3p. Furthermore, an association between increased miR-425-3p, cell death and reduced cell motility was defined in vitro in HCC cell lines treated with sorafenib. CONCLUSIONS: Assessment of miR-425-3p levels in liver biopsies could help in stratifying patients with advanced HCC for sorafenib treatment. These promising results need to be confirmed in a large prospective study.

BACKGROUND AND AIM: Time allowed for independent ethics committees (IECs) and administrative offices to assess and activate clinical trials is regulated by law. This study aims to describe time spent activating two multicentre non-profit trials supported by the Italian Medicines Agency (AIFA). Five non-AIFA supported (NAS) trials were used as a benchmark. METHODS: The two AIFA-supported trials were FATA-GIM3 (optimal adjuvant hormonal treatment for breast cancer) and TOSCA (duration of adjuvant FOLFOX in colorectal cancer). The five NAS trials focused on lung or ovarian cancer. The following were measured for all trials: date of submission of trial documentation to peripheral IEC, date of IEC opinion and date trial contracts were signed. Times are reported in months. RESULTS: 106 centres applied to participate in FATA-GIM3 and 137 in TOSCA. An IEC opinion was issued by 100/106 (1 negative opinion) and 137/137 (2 negative opinions) centres, with a median time from submission of 3.6â months (range 0.1-60.2). After a positive IEC opinion, the median time before signing the trial contract was 3.3â months (0.1-59.2). Contracts were signed with 93/99 and 135/135 centres, with a median time from submission of study documentation of 8.4â months (0.5-61.1). Times for NAS trials were not substantially different. CONCLUSIONS: FATA-GIM3 and TOSCA centres were opened after a median of 8â months, consisting of nearly 4â months each for IEC opinion and administrative signature, similar to the NAS trials. The process of trial activation in Italy remains inefficient and takes far longer than legally allowed.

BACKGROUND: Erlotinib is registered for treatment of all patients with advanced non-small-cell lung cancer (NSCLC). However, its efficacy for treatment of patients whose tumours are EGFR wild-type-which includes most patients-is still contentious. We assessed the efficacy of erlotinib compared with a standard second-line chemotherapy in such patients. METHODS: We did this randomised controlled trial in 52 Italian hospitals. We enrolled patients who had metastatic NSCLC, had had platinum-based chemotherapy, and had wild-type EGFR as assessed by direct sequencing. Patients were randomly assigned centrally (1:1) to receive either erlotinib orally 150 mg/day or docetaxel intravenously 75 mg/m(2) every 21 days or 35 mg/m(2) on days 1, 8, and 15, every 28 days. Randomisation was stratified by centre, stage, type of first-line chemotherapy, and performance status. Patients and investigators who gave treatments or assessed outcomes were not masked to treatment allocation, investigators who analysed results were. The primary endpoint was overall survival in the intention-to-treat population. The study is registered at ClinicalTrials.gov, number NCT00637910. FINDINGS: We screened 702 patients, of whom we genotyped 540. 222 patients were enrolled (110 assigned to docetaxel vs 112 assigned to erlotinib). Median overall survival was 8·2 months (95% CI 5·8-10·9) with docetaxel versus 5·4 months (4·5-6·8) with erlotinib (adjusted hazard ratio [HR] 0·73, 95% CI 0·53-1·00; p=0·05). Progression-free survival was significantly better with docetaxel than with erlotinib: median progression-free survival was 2·9 months (95% CI 2·4-3·8) with docetaxel versus 2·4 months (2·1-2·6) with erlotinib (adjusted HR 0·71, 95% CI 0·53-0·95; p=0·02). The most common grade 3-4 toxic effects were: low absolute neutrophil count (21 [20%] of 104 in the docetaxel group vs none of 107 in the erlotinib group), skin toxic effects (none vs 15 [14%]), and asthenia (ten [10%] vs six [6%]). INTERPRETATION: Our results show that chemotherapy is more effective than erlotinib for second-line treatment for previously treated patients with NSCLC who have wild-type EGFR tumours.

Pancreatic and periampullary cancers pose significant challenges in oncological care due to their complexity and diagnostic difficulties. Global experiences underscore the crucial role of multidisciplinary collaboration and centralized care in improving patient outcomes in this context. Recognizing these challenges, Lombardy, Italy's most populous region, embarked on establishing pancreas units across its territory to enhance clinical outcomes and organizational efficiency. This initiative, driven by a multistakeholder approach involving the Lombardy Welfare Directorate, clinicians, and a patient association, emphasizes the centralization of complex care in high-volume hospitals, adopting a hub-and-spoke model and a multidisciplinary approach. This article outlines the process and criteria set forth for pancreas unit implementation, aiming to provide a structured framework for enhancing pancreatic cancer care. Central to this initiative is the establishment of structured criteria and minimal requirements, not only for surgery but also for other essential components of care, ensuring a comprehensive approach to pancreatic cancer management. The Lombardy model offers a structured framework for enhancing pancreatic cancer care, with potential applicability to other regions and countries seeking to improve their cancer care infrastructure.
RESUMO
BACKGROUND: Despite contributions provided by the recent clinical trials, several issues and challenges still remain unsolved in adjuvant colon cancer (CC). Hence, further studies should be planned to better refine risk assessment as well as to establish the optimal treatment strategy in the adjuvant setting. However, it is necessary to request adequate, contemporary and relevant variables and report them homogeneously in order to bring maximal information when analyzing their prognostic value. MATERIAL AND METHODS: The project was devised to gain a consensus from experts engaged in the planning, accrual and analyses of stage II and III CC clinical trials, to identify mandatory and recommended baseline variables in order to i) harmonize future data collection worldwide in clinical trials dedicated to adjuvant treatment of CC; ii) propose guidance for Case Report Forms to be used for clinical trials in this setting. A total of 72 questions related to variables that should be reported and how to report them in adjuvant clinical trials were approved and then voted to reach a final consensus from panelists. RESULTS: Data items on patient-related factors, histopathological features, molecular profile, circulating biomarkers and blood analyses were analyzed and discussed by the whole expert panel. For each item, we report data supporting the acquired consensus and the relevant issues that were discussed. Nineteen items were deemed to be mandatory for resected stage III patients and 24 for resected stage II disease. In addition, 9 and 4 items were judged as recommended for stage III and II, respectively. CONCLUSION: In our opinion, these 28 variables should be used and uniformly reported in more comprehensive CRFs as research groups design future clinical trials in the field of adjuvant colon cancer.

PURPOSE: A number of studies suggest that older patients may have reduced or no benefit from the addition of oxaliplatin to fluoropyrimidines as adjuvant chemotherapy for stage III colon cancer (CC). MATERIALS AND METHODS: We studied the prognostic impact of age, as well as treatment adherence/toxicity patterns according to age, in patients with stage III CC who received 3 or 6 months of infusional fluorouracil, leucovorin, and oxaliplatin/capecitabine and oxaliplatin (CAPOX) on the basis of data collected from trials from the ACCENT and IDEA databases. Associations between age and time to recurrence (TTR), disease-free survival (DFS), overall survival (OS), survival after recurrence (SAR), and cancer-specific survival (CSS) were assessed by a Cox model or a competing risk model, stratified by studies and adjusted for sex, performance status, T and N stage, and year of enrollment. RESULTS: A total of 17,909 patients were included; 24% of patients were age older than 70 years (n = 4,340). Patients age ≥70 years had higher rates of early treatment discontinuation. Rates of grade ≥3 adverse events were similar between those older and younger than 70 years, except for diarrhea and neutropenia that were more frequent in older patients treated with CAPOX (14.2% v 11.2%; P = .01 and 12.1% v 9.6%; P = .04, respectively). In multivariable analysis, TTR was not significantly different between patients <70 years and those ≥70 years, but DFS, OS, SAR, and CSS were significantly shorter in those patients ≥70 years. CONCLUSION: In patients ≥70 years with stage III CC fit enough to be enrolled in clinical trials, oxaliplatin-based adjuvant chemotherapy was well tolerated and led to similar TTR compared with younger patients, suggesting similar efficacy. TTR may be a more appropriate end point for efficacy in this patient population.

BACKGROUND: Although obesity is an established risk factor for developing colon cancer, its prognostic impact and relation to patient sex in colon cancer survivors remains unclear. METHODS: The authors examined the prognostic and predictive impact of the body mass index (BMI) in patients with stage II and III colon carcinoma (N = 25,291) within the Adjuvant Colon Cancer Endpoints (ACCENT) database. BMI was measured at enrollment in randomized trials of 5-fluorouracil-based adjuvant chemotherapy. Association of BMI with the time to recurrence (TTR), disease-free survival (DFS), and overall survival (OS) were determined using Cox regression models. Statistical tests were 2-sided. RESULTS: During a median follow-up of 7.8 years, obese and underweight patients had significantly poorer survival compared with overweight and normal-weight patients. In a multivariable analysis, the adverse prognostic impact of BMI was observed among men but not among women (Pinteraction = .0129). Men with class 2 and 3 obesity (BMI ≥ 35.0 kg/m(2) ) had a statistically significant reduction in DFS (hazard ratio [HR], 1.16; 95% confidence interval [CI], 1.01-1.33; P = .0297) compared with normal-weight patients. Underweight patients had a significantly shorter TTR and reduced DFS (HR, 1.18; 95% CI, 1.09-1.28; P < .0001) that was more significant among men (HR, 1.31; 95% CI, 1.15-1.50; P < .0001) than among women (HR, 1.11; 95% CI, 1.01-1.23; P = .0362; Pinteraction = .0340). BMI was not predictive of a benefit from adjuvant treatment. CONCLUSIONS: Obesity and underweight status were associated independently with inferior outcomes in patients with colon cancer who received treatment in adjuvant chemotherapy trials.

BACKGROUND: Risk assessment models (RAMs) are relevant approaches to identify cancer outpatients at high risk of venous thromboembolism (VTE). Among the proposed RAMs, the Khorana (KRS) and the new-Vienna CATS risk scores have been externally validated in ambulatory patients with cancer. OBJECTIVES: To test KRS and new-Vienna CATS scores in 6-month VTE prediction and mortality in a large prospective cohort of metastatic cancer outpatients during chemotherapy. PATIENTS/METHODS: Newly diagnosed patients with metastatic non-small cell lung, colorectal, gastric, or breast cancers were analyzed (n = 1286). The cumulative incidence of objectively confirmed VTE was estimated with death as a competing risk and multivariate Fine and Gray regression. RESULTS: Within 6 months, 120 VTE events (9.7%) occurred. The KRS and the new-Vienna CATS scores showed comparable c-stat. Stratification by KRS provided VTE cumulative incidences of 6.2%, 11.4%, and 11.5% in the low-, intermediate-, and high-risk categories, respectively (p = ns), and of 8.5% vs. 11.8% (p = ns) in the low- vs. high-risk group by the single 2-point cut-off value stratification. Using a pre-defined 60-point cut-off by the new-Vienna CATS score, 6.6% and 12.2% cumulative incidences were obtained in the low- and high-risk groups, respectively (p < 0.001). Furthermore, having a KRS ≥2 = or a new-Vienna CATS score >60 points was also an independent risk factor for mortality. CONCLUSION: In our cohort, the 2 RAMs showed a comparable discriminating potential; however, after the application of cut-off values, the new-Vienna CATS score provided statistically significant stratification for VTE. Both RAMs proved to be effective in identifying patients at increased risk of mortality.

(1) Background: Venous thromboembolism (VTE) is a frequent complication in ambulatory lung cancer patients during chemotherapy and is associated with increased mortality. (2) Methods: We analyzed 568 newly diagnosed metastatic lung cancer patients prospectively enrolled in the HYPERCAN study. Blood samples collected before chemotherapy were tested for thrombin generation (TG) and a panel of hemostatic biomarkers. The Khorana risk score (KRS), new-Vienna CATS, PROTECHT, and CONKO risk assessment models (RAMs) were applied. (3) Results: Within 6 months, the cumulative incidences of VTE and mortality were 12% and 29%, respectively. Patients with VTE showed significantly increased levels of D-dimer, FVIII, prothrombin fragment 1 + 2, and TG. D-dimer and ECOG performance status were identified as independent risk factors for VTE and mortality by multivariable analysis and utilized to generate a risk score that provided a cumulative incidence of VTE of 6% vs. 25%, death of 19% vs. 55%, and in the low- vs. high-risk group, respectively (p < 0.001). While all published RAMs significantly stratified patients for risk of death, only the CATS and CONKO were able to stratify patients for VTE. (4) Conclusions: A new prediction model was generated to stratify lung cancer patients for VTE and mortality risk, where other published RAMs failed.
