Cetuximab every 2 weeks versus standard weekly dosing administration schedule.

Cetuximab every 2 weeks (Q2W) dosing schedule is approved by the US FDA and by the Japanese Pharmaceuticals and Medical Devices Agency in patients with metastatic colorectal cancer and squamous cell carcinoma of the head and neck. Phase II trials have found comparable efficacy and safety for the weekly (Q1W) and Q2W schedules, and real-world studies have shown noninferiority of the Q2W compared with the Q1W schedule. Several guidelines recommend cetuximab Q2W administration as an alternative to the Q1W dosing schedule. Cetuximab Q2W can be administered with a Q2W dose of chemotherapy, making it a more convenient option to the Q1W schedule, potentially resulting in reduced costs for administration, increased flexibility for clinical staff and improved patient adherence.

Cetuximab is a drug for patients with colorectal cancer or cancer of the head and neck. It is usually administered once a week. However, studies have shown that cetuximab given once every 2 weeks instead has similar clinical benefits and side effects. Based on this evidence, the every 2 weeks dosing schedule has been approved for use in USA and Japan. The every 2 weeks dosing schedule is a convenient alternative to the weekly schedule. It may result in fewer hospital visits, improved patient quality of life, reduced healthcare costs and more flexibility for medical staff. This review summarizes the current evidence and benefits for the every 2 weeks dosing schedule.

Atherosclerosis and the Bidirectional Relationship between Cancer and Cardiovascular Disease: From Bench to Bedside-Part 1.

Atherosclerosis, a complex metabolic-immune disease characterized by chronic inflammation driven by the buildup of lipid-rich plaques within arterial walls, has emerged as a pivotal factor in the intricate interplay between cancer and cardiovascular disease. This bidirectional relationship, marked by shared risk factors and pathophysiological mechanisms, underscores the need for a comprehensive understanding of how these two formidable health challenges intersect and influence each other. Cancer and its treatments can contribute to the progression of atherosclerosis, while atherosclerosis, with its inflammatory microenvironment, can exert profound effects on cancer development and outcomes. Both cancer and cardiovascular disease involve intricate interactions between general and personal exposomes. In this review, we aim to summarize the state of the art of translational data and try to show how oncologic studies on cardiotoxicity can broaden our knowledge of crucial pathways in cardiovascular biology and exert a positive impact on precision cardiology and cardio-oncology.

Trends in Asbestos Exposure and Malignant Mesothelioma Incidence in Emilia-Romagna Italy: A Retrospective Study 1996-2023.

Malignant mesothelioma (MM) is a rare but lethal cancer strongly associated with asbestos exposure. This retrospective study examines trends in asbestos exposure in Emilia-Romagna, Northern Italy. Between 1996 and 2023, 3,513 cases of MM were recorded, predominantly in males (72%) and in older than 65 years (79%). Occupational exposure accounted for 82% of cases, with a significant increase observed over time from 71% to 88% in the most recent period. A greater definition of professional exposure indicates that certain exposure has gone from 49% in the first period to 62% and 58% in the last two periods; probable exposure showed a decrease from 21% to 16% while possible exposure decreased from 16% to 13%. Familiar exposure remained relatively constant at around 8%, environmental exposure showed a slight decrease from 4% to 2%, while non-occupational exposure remained stable at 2%. Among patients with exclusively occupational exposure (1,826 cases), 87% were male and aged between 65 and 75 years (36%) and 75+ (41%). The exposure rates for the province of residence see the province of Reggio Emilia with the highest occupational exposure rate (2.5 x 100,000 residents), followed by Ravenna (2.3 x 100,000 residents) and Parma and Piacenza which have similar exposure rates with 2.2 x 100,000 residents. Professional sectors such as construction, railway maintenance and metalworking are identified as high-risk industries. Despite efforts to mitigate exposure, non-occupational and environmental exposures persist. The study highlights the importance of continuous surveillance and exposure monitoring to guide effective interventions and legal recognition of MM.

Implementation of Precision Oncology in Clinical Practice: Results of a National Survey for Health Care Professionals.

BACKGROUND: Two main aspects lead the implementation of precision oncology into clinical practice: the adoption of extended genome sequencing technologies and the institution of the Molecular Tumor Boards (MTBs). CIPOMO (Italian Association of Heads of Oncology Department) promoted a national survey across top health care professionals to gain an understanding of the current state of precision oncology in Italy. METHODS: Nineteen questions were sent via the SurveyMonkey platform to 169 heads of oncology departments. Their answers were collected in February 2022. RESULTS: Overall, 129 directors participated; 113 sets of answers were analyzed. Nineteen regions out of 21 participated as a representative sample of the Italian health care system. The use of next-generation sequencing (NGS) is unevenly distributed; informed consent and clinical reports are managed differently, as the integration of medical, biologic, and informatics domains in a patient-centered workflow is inconsistent. A heterogeneous MTB environment emerged. A total of 33.6% of the responding professionals did not have access to MTBs while 76% of those who have did not refer cases. CONCLUSIONS: NGS technologies and MTBs are not homogeneously implemented in Italy. This fact potentially jeopardizes equal access chances to innovative therapies for patients. This survey was carried out as part of an organizational research project, pursuing a bottom-up approach to identify the needs and possible solutions to optimize the process. These results could be a starting point for clinicians, scientific societies, and health care institutions to outline the best practices and offer shared recommendations for precision oncology implementation in current clinical practice.

Implementation of precision medicine in healthcare-A European perspective.

The technical development of high-throughput sequencing technologies and the parallel development of targeted therapies in the last decade have enabled a transition from traditional medicine to personalized treatment and care. In this way, by using comprehensive genomic testing, more effective treatments with fewer side effects are provided to each patient-that is, precision or personalized medicine (PM). In several European countries-such as in England, France, Denmark, and Spain-the governments have adopted national strategies and taken "top-down" decisions to invest in national infrastructure for PM. In other countries-such as Sweden, Germany, and Italy with regionally organized healthcare systems-the profession has instead taken "bottom-up" initiatives to build competence networks and infrastructure to enable equal access to PM. In this review, we summarize key learnings at the European level on the implementation process to establish sustainable governance and organization for PM at the regional, national, and EU/international levels. We also discuss critical ethical and legal aspects of implementing PM, and the importance of access to real-world data and performing clinical trials for evidence generation, as well as the need for improved reimbursement models, increased cross-disciplinary education and patient involvement. In summary, PM represents a paradigm shift, and modernization of healthcare and all relevant stakeholders-that is, healthcare, academia, policymakers, industry, and patients-must be involved in this system transformation to create a sustainable, non-siloed ecosystem for precision healthcare that benefits our patients and society at large.

Rationale and design of the PROMETCO study: a real-world, prospective, longitudinal cohort on the continuum of care of metastatic colorectal cancer from a clinical and patient perspective.

The PROMETCO study is collecting real-world data on metastatic colorectal cancer (mCRC) patients with two progressions. This international, prospective, longitudinal, observational cohort study is collecting data on mCRC patients with two disease progressions since diagnosis and receiving subsequent treatment. Objectives include overall survival, treatment patterns, effectiveness and safety and patient-reported outcomes using the EuroQol 5-level, 5-dimensional questionnaire, the Brief Fatigue Inventory and a modified version of the ACCEPTance by the Patients of their Treatment (ACCEPT©) questionnaire. Data are collected retrospectively and prospectively up to 18 months. As of 13 October 2021, 544 patients from 18 countries had been enrolled. To the authors' knowledge, PROMETCO is the first international, real-world study of the continuum of care of mCRC patients in this setting. Trial registration number: NCT03935763 (ClinicalTrials.gov).

Supportive therapies in the prevention of chemotherapy-induced febrile neutropenia and appropriate use of granulocyte colony-stimulating factors: a Delphi consensus statement.

PURPOSE: Data indicate that the use of prophylactic granulocyte colony-stimulating factors (G-CSFs) for chemotherapy-induced febrile neutropenia (FN) in routine practice is not consistent with guideline recommendations. The initiative "supportive care for febrile neutropenia prevention and appropriateness of G-CFS use" was undertaken to address the issue of inappropriate prescription of G-CSFs and to improve guideline adherence in the treatment of FN. METHODS: In a two-round Delphi procedure, 36 medical oncologists reviewed clinically relevant recommendations on risk assessment, the appropriate use of G-CSFs, and the prevention of FN based on available literature and individual clinical expertise. RESULTS: The consensus was reached on 16 out of 38 recommendations, which are backed by evidence from randomised clinical trials and routine clinical practice. The medical oncologists agreed that the severity of neutropenia depends on patients' characteristics and chemotherapy intensity, and therefore, the risk of severe neutropenia or FN should be assessed at each chemotherapy cycle so as to initiate prophylaxis with G-CSFs if required. The use of biosimilar G-CSFs, with similar efficacy and safety profiles to the originator biologic, has improved the availability and sustainability of cancer care. The timing of supportive therapy is crucial; for example, long-acting G-CSF should be administered 24-72 h after chemotherapy administration. Each biological agent has a recommended administration dose and duration, and it is important to follow these recommendations to avoid complications associated with under-prophylaxis. CONCLUSION: It is hoped that these statements will help to increase adherence to guideline recommendations for appropriate G-CSF use and improve patient care.

Incidence of malignant mesothelioma and asbestos exposure in the Emilia-Romagna region, Italy.

BACKGROUND: The aim of this study is to describe the incidence of malignant mesothelioma (MM) and asbestos exposure in an Italian region in the period 1996-June 2021. METHODS: The study included cases with microscopic confirmation and those with instrumental confirmation. For each case, information on sex, age, tumour site, morphology and date of diagnosis was collected, along with details of exposure to asbestos. RESULTS: 3,097 cases of MM (2,233 males and 864 females) were registered: 90.8% with microscopic confirmation. A total of 2,840 cases involved the pleura (92%), 230 cases the peritoneum (7%), and a small number of cases the pericardium and testis (9 and 18, respectively). Most cases (78.0%) occurred after 65 years of age, while only 1.5% concerned individuals with age < 45 years. The standardized incidence rate for the entire period (adjusted to the 2000 Italian standard population and calculated per 100,000 person-years) was equal to 3.9 in males and 1.4 in females, and the trend showed an increase with age in both sexes. Concerning asbestos exposure, 79.7% of cases were exposed (86.7% males and 60.1% females). In 70.3%, exposure was occupational (83.4% males and 33.2% females), while 20.7% of females and 0.8% of males had familial exposure. Building construction, rolling stock manufacture/repair and metalworking were the most prevalent economic activities associated with occupational exposure. CONCLUSIONS: This study offers an overview of MM in an Italian region characterized by high incidence and high exposure due to its particular production activities.

Gemcitabine with or without ramucirumab as second-line treatment for malignant pleural mesothelioma (RAMES): a randomised, double-blind, placebo-controlled, phase 2 trial.

BACKGROUND: There is a preclinical rationale for inhibiting angiogenesis in mesothelioma. We aimed to assess the efficacy and safety of the anti-VEGFR-2 antibody ramucirumab combined with gemcitabine in patients with pretreated malignant pleural mesothelioma. METHODS: RAMES was a multicentre, randomised, double-blind, placebo-controlled, phase 2 trial done at 26 hospitals in Italy. Eligible patients were aged 18 years or older, had Eastern Cooperative Oncology Group performance status 0-2, and histologically proven malignant pleural mesothelioma progressing during or after first-line treatment with pemetrexed plus platinum. Patients were randomly assigned (1:1) to receive intravenous gemcitabine 1000 mg/m2 on days 1 and 8 every 3 weeks plus either intravenous placebo (gemcitabine plus placebo group) or ramucirumab 10 mg/kg (gemcitabine plus ramucirumab group) on day 1 every 3 weeks, until tumour progression or unacceptable toxicity. Central randomisation was done according to a minimisation algorithm method, associated with a random element using the following stratification factors: ECOG performance status, age, histology, and first-line time-to-progression. The primary endpoint was overall survival, measured from the date of randomisation to the date of death from any cause. Efficacy analyses were assessed in all patients who had been correctly randomised and received their allocated treatment, and safety analyses were assessed in all patients who received at least one dose of their assigned treatment. This trial is registered with ClinicalTrials.gov, NCT03560973, and with EudraCT, 2016-001132-36. FINDINGS: Between Dec 22, 2016, and July 30, 2018, of 165 patients enrolled 161 were correctly assigned and received either gemcitabine plus placebo (n=81) or gemcitabine plus ramucirumab (n=80). At database lock (March 8, 2020), with a median follow-up of 21·9 months (IQR 17·7-28·5), overall survival was longer in the ramucirumab group (HR 0·71, 70% CI 0·59-0·85; p=0·028). Median overall survival was 13·8 months (70% CI 12·7-14·4) in the gemcitabine plus ramucirumab group and 7·5 months (6·9-8·9) in the gemcitabine plus placebo group. Grade 3-4 treatment-related adverse events were reported in 35 (44%) of 80 patients in the gemcitabine plus ramucirumab group and 24 (30%) of 81 in the gemcitabine plus placebo group. The most common treatment-related grade 3-4 adverse events were neutropenia (16 [20%] for gemcitabine plus ramucirumab vs ten [12%] for gemcitabine plus placebo) and hypertension (five [6%] vs none). Treatment-related serious adverse events were reported in five (6%) in the gemcitabine plus ramucirumab group and in four (5%) patients in the gemcitabine plus placebo group; the most common was thromboembolism (three [4%] for gemcitabine plus ramucirumab vs two [2%] for gemcitabine plus placebo). There were no treatment-related deaths. INTERPRETATION: Ramucirumab plus gemcitabine significantly improved overall survival after first-line standard chemotherapy, with a favourable safety profile. This combination could be a new option in this setting. FUNDING: Eli Lilly Italy. TRANSLATION: For the Italian translation of the abstract see Supplementary Materials section.

Cumulative COVID-19 incidence, mortality and prognosis in cancer survivors: A population-based study in Reggio Emilia, Northern Italy.

The aim of this population-based study was to evaluate the impact of being a cancer survivor (CS) on COVID-19 risk and prognosis during the first wave of the pandemic (27 February 2020 to 13 May 2020) in Reggio Emilia Province. Prevalent cancer cases diagnosed between 1996 and 2019 were linked with the provincial COVID-19 surveillance system. We compared CS' cumulative incidence of being tested, testing positive for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), being hospitalized and dying of COVID-19 with that of the general population; we compared COVID-19 prognosis in CS and in patients without cancer. During the study period, 15 391 people (1527 CS) underwent real-time polymerase chain reaction for SARS-CoV-2, of whom 4541 (447 CS) tested positive; 541 (113 CS) died of COVID-19. CS had higher age- and sex-adjusted incidence rate ratios (IRR) of testing (1.28 [95% confidence interval, CI = 1.21-1.35]), of positive test (IRR 1.06 [95% CI = 0.96-1.18]) and of hospitalization and death (IRR 1.27 [95% CI = 1.09-1.48] and 1.39 [95%CI = 1.12-1.71], respectively). CS had worse prognosis when diagnosed with COVID-19, particularly those below age 70 (adjusted odds ratio [OR] of death 5.03; [95% CI = 2.59-9.75]), while the OR decreased after age 70. The OR of death was higher for CS with a recent diagnosis, that is, <2 years (OR = 2.92; 95% CI = 1.64-5.21), or metastases (OR = 2.09; 95% CI = 0.88-4.93). CS showed the same probability of being infected, despite a slightly higher probability of being tested than the general population. Nevertheless, CS were at higher risk of death once infected.

Avelumab treatment in Italian patients with metastatic Merkel cell carcinoma: experience from an expanded access program.

BACKGROUND: The incidence of Merkel cell carcinoma (MCC), a rare form of skin cancer with a poor prognosis, has increased in Italy in recent decades. Avelumab, an anti-programmed death ligand 1 monoclonal antibody, is approved for the treatment of metastatic MCC (mMCC) based on the results of the phase 2 JAVELIN Merkel 200 trial. The global avelumab expanded access program (EAP) was designed to provide compassionate use of avelumab prior to approval for patients with mMCC who had limited treatment options. We report findings from a subgroup of Italian patients enrolled in the avelumab EAP. METHODS: Eligible patients had mMCC and progressive disease following ≥ 1 prior line of chemotherapy or were ineligible for chemotherapy or clinical trial participation. Patients received avelumab 10 mg/kg intravenously every 2 weeks. Treating physicians were provided with an initial 3-month supply of avelumab; resupply was permitted if the patient achieved a complete response, partial response, stable disease, or other clinical benefit per physician assessment. Safety and efficacy data for the EAP were reported at the treating physician's discretion. RESULTS: Between April 1, 2016, and September 14, 2018, 109 requests for avelumab were received from Italy, and 102 were approved. All but 1 of the approved patients had received ≥ 1 prior line of therapy. At data cutoff (March 22, 2019), 95 patients had been supplied with avelumab and response data were available for 55 patients. The objective response rate in response-evaluable patients was 29.1%, including 6 patients (10.9%) who achieved a complete response and 10 patients (18.2%) who achieved a partial response; in the total population supplied with avelumab (n = 95), the proportion who had an objective response was 16.8%. The median duration of treatment in responding patients was 9.7 months (range, 3.5-41.7 months). The most frequently reported treatment-related adverse events were infusion-related reaction (single preferred term; n = 3 [3.2%]) and pyrexia (n = 2 [2.1%]). CONCLUSIONS: Results from Italian patients enrolled in the avelumab EAP are consistent with the findings of the JAVELIN Merkel 200 trial and confirm the efficacy and safety of avelumab treatment in this population.

Baseline liver steatosis has no impact on liver metastases and overall survival in rectal cancer patients.

BACKGROUND: The liver is one of the most frequent sites of metastases in rectal cancer. This study aimed to evaluate how the development of synchronous or metachronous liver metastasis and overall survival are impacted by baseline liver steatosis and chemotherapy-induced liver damage in rectal cancer patients. METHODS: Patients diagnosed with stage II to IV rectal cancer between 2010 and 2016 in our province with suitable baseline CT scan were included. Data on cancer diagnosis, staging, therapy, outcomes and liver function were collected. CT scans were retrospectively reviewed to assess baseline steatosis (liver density < 48 HU and/or liver-to-spleen ratio < 1.1). Among patients without baseline steatosis and treated with neoadjuvant chemotherapy, chemotherapy-induced liver damage was defined as steatosis appearance, ≥ 10% liver volume increase, or significant increase in liver function tests. RESULTS: We included 283 stage II to IV rectal cancer patients with suitable CT scan (41% females; mean age 68 ± 14 years). Steatosis was present at baseline in 90 (31.8%) patients, synchronous liver metastasis in 42 (15%) patients and metachronous liver metastasis in 26 (11%); 152 (54%) deaths were registered. The prevalence of synchronous liver metastasis was higher in patients with steatosis (19% vs 13%), while the incidence of metachronous liver metastasis was similar. After correcting for age, sex, stage, and year of diagnosis, steatosis was not associated with metachronous liver metastasis nor with overall survival. In a small analysis of 63 patients without baseline steatosis and treated with neoadjuvant chemotherapy, chemotherapy-induced liver damage was associated with higher incidence of metachronous liver metastasis and worse survival, results which need to be confirmed by larger studies. CONCLUSIONS: Our data suggest that rectal cancer patients with steatosis had a similar occurrence of metastases during follow-up, even if the burden of liver metastases at diagnosis was slightly higher, compatible with chance.

Molecular tests and target therapies in oncology: recommendations from the Italian workshop.

Next-generation sequencing (NGS) and liquid biopsy are new technologies that can allow overall tumor profiling in a single analysis and play an important role in the implementation of precision oncology. However, the lack of guidelines in this setting has limited the development of precision oncology in Italy. This article summarizes recommendations for the appropriate use of NGS in tumor gene profiling, as well as access to tests and target drugs, that were prepared by a group of key opinion leaders and relevant stakeholders. In particular, the need to create laboratory networks capable of carrying out NGS tests in Italy is highlighted. It also appears necessary to establish an adequate reimbursement system for NGS tests. However, the expert panel recommends that the use of NGS tests in clinical practice should be limited to specific tumor types, based on the number and complexity of biomarkers and the availability of treatments.

Lay abstract The increasingly precise and extensive characterization of tumors through gene profiling allows a greater understanding of the molecular mechanisms underlying tumor growth, thus permitting better, more personalized therapeutic options. In the past two decades, tests to individually profile genes (molecular alterations) of different tumors ­ including lung, stomach, colorectal, breast, ovarian cancer and melanoma ­ into clinical practice have been introduced, allowing patients who carry specific genomic alterations greater access to more effective therapies. The first phase of the era of genomic profiling was limited to the identification of molecular alterations, each detectable with a specific test, aiming to define the sensitivity/resistance to a single drug and for a specific cancer site. The second phase of precision medicine determined several molecular alterations tested for single cancer types, often with different techniques. We have now reached a third phase, characterized by important technological developments and, in particular, by the introduction of next-generation sequencing (NGS) and liquid biopsy (using patients' blood). These techniques allow a comprehensive genomic profile of the tumor in a single analysis using the same biological sample. These new techniques have led to the selection of increasingly precise patient candidates for target therapy and then to the monitoring of their treatment, together with identification of resistant tumor clones. However, the lack of guidelines in this setting has limited the development of precision medicine in Italy. This article reports a summary of recommendations for appropriate indications in tumor gene profiling, as well as for access to tests and target drugs, that were prepared by a group of key opinion leaders and relevant stakeholders.

Appropriateness of trifluridine/tipiracil in the clinical practice of third-line therapy in metastatic colorectal cancer.

Aim: To help to remove misperception of an appropriate position of trifluridine/tipiracil (FTD/TPI) in the treatment of metastatic colorectal cancer. Materials & methods: The RAND Corporation/UCLA Appropriateness Method was used by a panel of Italian experts to develop recommendations concerning daily practice with FTD/TPI. Forty-three clinical scenarios were discussed in two rounds and the resulting statements were rated as appropriate, uncertain or inappropriate, according to the median score. Results: Several topics were dealt with, covering the profile of eligible patients, therapeutic options beyond the second line, the practice of treatment with FTD/TPI, evaluation and efficacy and toxicity, as well as costs and compliance. Conclusion: FTD/TPI is an important therapeutic resource in refractory metastatic colorectal cancer that combines manageability and safety.

Sequencing radium 223 and other life-prolonging agents in castration-resistant prostate cancer patients.

Background: Radium 223 (RA223) is currently administered as part of a therapeutic sequence with the other life-prolonging agents (LPAs) for metastatic castration-resistant prostate cancer (mCRPC). Patients & methods: We retrospectively reviewed the clinical records of patients who had received at least three LPAs including RA223. Results: Median overall survival (OS) from the start of first-line treatment was 39.8 months, with the patients who completed all six planned courses of RA223 having a longer OS than those who did not (53.2 vs 29.5 months; p < 0.0001). Conclusions: Our study confirms the activity of RA223 regardless of the treatment line in which it is administered and suggests that patient selection plays a central role in maximizing this activity.

Colon cancer survival differs from right side to left side and lymph node harvest number matter.

BACKGROUND: Right-sided colorectal cancer (CRC) has worse survival than does left-sided CRC. The objective of this study was to further assess the impact of right-side location on survival and the role of the extent of lymphadenectomy. METHODS: All CRCs diagnosed between 2000 and 2012 in Emilia-Romagna Region, Italy, were included. Data for stage, grade, histology, screening history, and number of removed lymph nodes (LN) were collected. Multivariable Cox regression models were used to estimate hazard ratios (HR), with relative 95% confidence intervals (95%CI), of right vs. left colon and of removing < 12, 12-21 or > 21 lymph nodes by cancer site. RESULTS: During the study period, 29,358 patients were registered (8828 right colon, 18,852 left colon, 1678 transverse). Patients with right cancer were more often older, females, with advanced stage and high grade, and higher number of removed LNs. Five-year survival was lower in the right than in the left colon (55.2% vs 59.7%). In multivariable analysis, right colon showed a lower survival when adjusting for age, sex, and screening status (HR 1.12, 95%CI 1.04-1.21). Stratification by number of lymph nodes removed (12-21 or > 21) was associated with better survival in right colon (HR 0.54, 95%CI 0.40-0.72 and HR 0.40, 95%CI 0.30-0.55, respectively) compared to left colon (HR 0.89, 95%CI 0.76-1.06 and HR 0.83, 95%CI 0.69-1.01, respectively). CONCLUSIONS: This study confirms that right CRC has worse survival; the association is not due to screening status. An adequate removal of lymph nodes is associated with better survival, although the direction of the association in terms of causal links is not clear.

Phase II study on first-line treatment of NIVolumab in combination with folfoxiri/bevacizumab in patients with Advanced COloRectal cancer RAS or BRAF mutated - NIVACOR trial (GOIRC-03-2018).

BACKGROUND: FOLFOXIRI (fluorouracil, leucovorin, oxaliplatin, and irinotecan) plus bevacizumab has shown to be one of the therapeutic regimens in first line with the highest activity in patients (pts.) with metastatic colorectal cancer (mCRC) unselected for biomolecular alterations. Generally, tumors co-opt the programmed death-1/ligand 1 (PD-1/PD-L1) signaling pathway as one key mechanism to evade immune surveillance. As today, anti-PD-1 monoclonal antibodies are FDA approved only for DNA mismatch repair deficient/microsatellite instability-high (MMRd/MSI-H), which represent only about 5% among all mCRC. Nowadays, there are no data demonstrating anti PD-1 activity in proficient and stable disease (MMRp/MSS). A different target in mCRC is also the Vascular Endothelial Growth Factor A (VEGF-A), which acts on endothelial cells to stimulate angiogenesis. VEGF-A inhibition with bevacizumab has shown to increase the immune cell infiltration, providing a solid rationale for combining VEGF targeted agents with immune checkpoint inhibitors. Based on these evidences, we explore the combination of triplet chemotherapy (FOLFOXIRI) with bevacizumab and nivolumab in pts. with mCRC RAS/BRAF mutant regardless of microsatellite status. METHODS/DESIGN: This is a prospective, open-label, multicentric phase II trial where pts. with mCRC RAS/BRAF mutated, in first line will receive nivolumab in combination with FOLFOXIRI/bevacizumab every 2 weeks for 8 cycles followed by maintenance with bevacizumab plus nivolumab every 2 weeks. Bevacizumab will be administered intravenously at dose of 5 mg/kg every 2 weeks and nivolumab intravenously as a flat dose of 240 mg every 2 weeks. The primary endpoint is the overall response rate (ORR). This study hypothesis is that the treatment is able to improve the ORR from 66 to 80%. Secondary endpoints include OS, safety, time to progression, duration of response. Collateral translational studies evaluate the i) tumor mutational burden, and ii) genetic alterations by circulating free DNA (cfDNA) obtained from plasma samples. The trial is open to enrollment, 9 of planned 70 pts. have been enrolled. TRIAL REGISTRATION: NIVACOR is registered at ClinicalTrials.gov: NCT04072198 , August 28, 2019.

Fighting cancer in coronavirus disease era: organization of work in medical oncology departments in Emilia Romagna region of Italy.

Aim: To assess the measures applied to reduce the spread of coronavirus disease (COVID-19) and the timing of their application in medical oncology departments. Materials & methods: We surveyed all medical oncology departments from the Italian Emilia Romagna region via a multidomain questionnaire. The questions covered items on patients, healthcare workers, risk reduction measure and clinical trials. Results: A total of 12 centers involving 861 healthcare members joined the survey. The measures applied to patients and health workers partially converged in all the departments while major divergences were found in the clinical trials domain. High rate of COVID-19 infection occurred among medical doctors (21/208, 10.1%) and social care workers (13/110, 11.8%). Rate of infection among nurses was 5.7% (24/418). Conclusion: All measures able to reduce risk of COVID-19 infection must be applied in medical oncology departments. Early introduction of risk reduction measures may be a critical issue.

Oral anticancer therapy project: Clinical utility of a specific home care nursing programme on behalf of Italian Association of Medical Oncology (AIOM).

AIMS AND OBJECTIVES: To assess the effectiveness of a specific home care nursing programme in addition to standard care in patients (pts) receiving oral anticancer treatments. BACKGROUND: Oral anticancer therapy present challenges for pts since treatment is a home-based therapy. This study evaluates the potentiality of a home care nursing programme in decreasing hospital accesses for not severe toxicity. METHODS: This is an open-label, multicentre, randomised trial including pts who were receiving an anticancer oral drug. The study complies with the CONSORT checklist published in 2010. Concomitant use of radiation therapy, intravenous or metronomic therapies, or the intake of previous oral drugs was not allowed. Pts were randomly assigned to home care nursing programme (A) or standard care (B). In arm A, dedicated nurses provided information to pts, a daily record on which pts would take note of drugs and dosages and a telephone monitoring during the first two cycles of therapy. The primary outcome was the reduction in improper hospital accesses for grade 1-2 toxicity according to CTCAE v4.0. RESULTS: Out of 432 randomised pts, 378 were analysed (184 pts in arm A and 194 in arm B). Hospital accesses were observed in 41 pts in arm A and in 42 pts in arm B (22.3% vs. 21.6%, respectively). No difference was detected in proportion of improper accesses between arm A and arm B (29.3% vs. 23.8%, respectively). CONCLUSIONS: Our experience failed to support the role of a specific home care nursing programme for pts taking oral chemotherapy. An improved attention to specific educational practice and information offered to pts can explain these results. RELEVANCE TO CLINICAL PRACTICE: Our results underline the role of nurse educational practice and information offered to patients. A careful nurse information of patients about drugs is essential to reduce toxicities avoiding the opportunity of a specific home monitoring.

The clinical relevance of multiple DPYD polymorphisms on patients candidate for fluoropyrimidine based-chemotherapy. An Italian case-control study.

BACKGROUND: Deleterious polymorphisms in the gene encoding DPD (DPYD) may result in severe reduction of DPD enzymatic activity that causes life-threatening toxicities when the standard dose of fluorouracil is used. The best panel of single-nucleotide polymorphism (SNPs) of DPYD is not well defined. METHODS: In 2011, we began screening DPYD*2A in patients candidate for fluoropyrimidine-based chemotherapy. We planned a case-control study with all cases of DPYD*2A wild type who developed toxicity ≥G3 and with a cohort of patients who did not present severe toxicities. Then, we tested the additional SNPs: c.2846A>T, c.1679T>G, c.2194G>A. RESULTS: From 2011 to 2016, we screened 1827 patients for DPD deficiency; of those, 31 subjects (1.7%) showed DPYD*2A SNP. We selected 146 subjects who developed severe toxicities (Cases) and 220 patients who experienced no or mild toxicities (Controls); 53 patients carried one of the additional SNPs: 35 subjects (66%) fell into the Cases and 18 (34%) into the Controls (p < 0.0001). c.2194G>A was the most frequent SNP (12.5%) and showed a correlation with neutropenia. We confirmed that c.2846A>T and c.1679T>G were related to various toxicities. CONCLUSIONS: The additional DPYD polymorphisms could enhance the prevention of fluoropyrimidine toxicity. c.2194G>A is the most frequent polymorphism and it was found to be associated with neutropenia.
