RESUMEN
PURPOSE: Patients with haematologic malignancies have less access to palliative care and are referred later than patients with solid tumours. We developed a survey to investigate this phenomenon, with the intention of analysing palliative care perceptions among health professionals who treat haematology patients and identifying barriers and facilitators to referrals to palliative care services. METHODS: This was a multicentre exploratory descriptive web-based survey. A questionnaire was administered to 320 medical and nursing staff members from five Italian haematological units and San Marino's hospital to investigate their perception of palliative care. Quantitative and qualitative analyses were performed. RESULTS: A total of 142/320 healthcare professionals completed the survey, achieving a 44% response rate. Most of the respondents supported the integration of haematology and palliative care and were aware of the role of palliative care. Despite this, only half had an in-hospital palliative care team, and only a few had previously attended a specific training course. The majority agreed with palliative care referral when the prognosis was less than 3 months or when the symptoms were incoercible and with blood transfusions even in the last stages of the disease. Many considered the presence of an in-hospital palliative care team or a case manager, as well as structured palliative care training, as fundamental facilitators of palliative care referrals. CONCLUSION: These results showed that healthcare professionals in haematology generally hold a favourable attitude and a high interest in integrating palliative care into their patients' care. The low referral rate could depend on clinical, cultural, and organisational issues.

BACKGROUND: Colon cancer in young patients is often associated with hereditary syndromes; however, in early-onset rectal cancer, mutations of these genes are rarely observed. The aim of this study was to analyse the features of the local immune microenvironment and the mutational pattern in early-onset rectal cancer. METHODS: Commonly mutated genes were analysed within a rectal cancer series from the University Hospital of Padova. Mutation frequency and immune gene expression in a cohort from The Cancer Genome Atlas ('TCGA') were compared and immune-cell infiltration levels in the healthy rectal mucosa adjacent to rectal cancers were evaluated in the IMMUNOlogical microenvironment in REctal AdenoCarcinoma Treatment 1 and 2 ('IMMUNOREACT') series. RESULTS: In the authors' series, the mutation frequency of BRAF, KRAS, and NRAS, as well as microsatellite instability frequency, were not different between early- and late-onset rectal cancer. In The Cancer Genome Atlas series, among the genes with the most considerable difference in mutation frequency between young and older patients, seven genes are involved in the immune response and CD69, CD3, and CD8ß expression was lower in early-onset rectal cancer. In the IMMUNOlogical microenvironment in REctal AdenoCarcinoma Treatment 1 and 2 series, young patients had a lower rate of CD4+ T cells, but higher T regulator infiltration in the rectal mucosa. CONCLUSION: Early-onset rectal cancer is rarely associated with common hereditary syndromes. The tumour microenvironment is characterized by a high frequency of mutations impairing the local immune surveillance mechanisms and low expression of immune editing-related genes. A constitutively low number of CD4 T cells associated with a high number of T regulators indicates an imbalance in the immune surveillance mechanisms.
RESUMEN
Isocitrate dehydrogenase wild-type glioblastoma is the most frequent primary brain tumor in adult patients and its prognosis is still dismal with a median survival of about 1 year. BRAF V600E mutation, an important target for personalized therapy, has been identified in about 3% of these patients, but few data are available from prospective studies on the role of anti-BRAF drugs in adult glioblastoma patients. Moreover, SOX2 gene amplification and overexpression can represent an important mechanism of resistance to BRAF inhibitors by STAT3 gene activation. We present the case of a heavily pretreated 42-year-old man with BRAF V600E mutant and SOX2 amplification glioblastoma having a radiologic and metabolic [analyzed by a brain 18F-fluoro-ethyl-tyrosine([18F]FET) PET/MRI] complete response to the combination therapy with dabrafenib plus trametinib and silybin, a potent STAT3 inhibitor. The patient is currently undergoing treatment after a total of 24 months of continuation therapy with a good safety profile. In conclusion, we showed a promising activity of the personalized treatment of BRAF and MEK inhibitors in patient with BRAF V600E mutant glioblastoma; silybin can play an important role in decreasing drug resistance during BRAF inhibitor therapy, especially in patients with SOX2 amplification.

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.

BACKGROUND: The RCC treatment landscape has evolved dramatically over the past decade. The purpose of this study is to present a real-world data estimation of RCC's cost-of-illness for this tumour's clinical pathway. METHODS: This investigation is a population-based cohort study using real-world data, which considers all RCC incident cases diagnosed in Local Unit 6 of the Province of Padua in 2016 and 2017 as registered by the Veneto Cancer Registry. Data on drug prescriptions, the use of medical devices, hospital admissions, and visits to outpatient clinics and emergency departments were collected by means of administrative databases. We evaluated the costs of all healthcare procedures performed in the 2 years of follow-up post-RCC diagnosis. The overall and annual average real-world costs per patient, both as a whole and by single item, were calculated and stratified by stage of disease at diagnosis. RESULTS: The analysis involved a population of 148 patients with a median age of 65.8 years, 66.22% of whom were male. Two years after diagnosis, the average total costs amounted to 21,429 per patient. There is a steady increment in costs with increasing stage at diagnosis, with a total amount of 41,494 spent 2 years after diagnosis for stage IV patients, which is 2.44 times higher than the expenditure for stage I patients (17,037). In the first year, hospitalization appeared to be the most expensive item for both early and advanced disease. In the second year, however, outpatient procedures were the main cost driver in the earlier stages, whereas anticancer drugs accounted for the highest costs in the advanced stages. CONCLUSIONS: This observational study provides real-world and valuable estimates of RCC's cost-of-illness, which could enable policymakers to construct dynamic economic cost-effectiveness evaluation models based on real world costs' evaluation.

The novel coronavirus disease 2019 has grown to be a global public health emergency. The rapid spread of the infection has raised many questions in the oncohematological scientific community regarding the appropriateness of high-dose chemotherapy with autologous stem cell transplantation (ASCT). We here report two cases of patients who received ASCT at our Institute during the epidemic in Italy, affected with Hodgkin lymphoma and germ cell tumor, respectively. The two patients underwent a nasopharyngeal swab for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) on hospital admittance and during the period of bone marrow aplasia. They were attended to exclusively by dedicated health care staff who followed specifically implemented protocols for bedside nursing and care. They completed the procedure without unexpected side effect. Our experience demonstrates how ASCT can be performed safely if procedures are reorganized ad hoc to reduce the risk of SARS-CoV-2 infection.

BACKGROUND: Circulating tumor cells (CTCs) correlate with adverse prognosis in patients with breast, colorectal, lung, and prostate cancer. Little data are available for renal cell carcinoma (RCC). MATERIALS AND METHODS: We designed a multicenter prospective observational study to assess the correlation between CTC counts and progression-free survival (PFS) in patients with metastatic RCC treated with an antiangiogenic tyrosine kinase inhibitor as a first-line regimen; overall survival (OS) and response were secondary objectives. CTC counts were enumerated by the CellSearch system at four time points: day 0 of treatment, day 28, day 56 and then at progression, or at 12 months in the absence of progression. RESULTS: One hundred ninety-five eligible patients with a median age of 69 years were treated with sunitinib (77.5%) or pazopanib (21%). At baseline, 46.7% of patients had one or more CTCs per milliliter (range, 1 to 263). Thirty patients had at least three CTCs, with a median PFS of 5.8 versus 15 months in the remaining patients (p = .002; hazard ratio [HR], 1.99), independently of the International Metastatic RCC Database Consortium score at multivariate analysis (HR, 1.91; 95% confidence interval [CI], 1.16-3.14). Patients with at least three CTCs had a shorter estimated OS of 13.8 months versus 52.8 months in those with fewer than three CTCs (p = .003; HR, 1.99; multivariate analysis HR, 1.67; 95% CI, 0.95-2.93). Baseline CTC counts did not correlate with response; neither did having CTC sequencing counts greater than or equal to one, two, three, four, or five. CONCLUSION: We provide prospective evidence that the presence of three or more CTCs at baseline is associated with a significantly shorter PFS and OS in patients with metastatic RCC. IMPLICATIONS FOR PRACTICE: This prospective study evaluated whether the presence of circulating tumor cells (CTCs) in the peripheral blood correlates with activity of first-line tyrosine kinase inhibitors in metastatic renal cell carcinoma (RCC). This study demonstrated that almost half of patients with metastatic RCC have at least one CTC in their blood and that those patients with at least three CTCs are at increased risk of early progressive disease and early death due to RCC. Studies incorporating CTC counts in the prognostic algorithms of metastatic RCC are warranted.

BACKGROUND: Cabozantinib inhibits tyrosine kinases, including vascular endothelial growth factor receptors 1, 2, and 3, MET, and AXL, which are implicated in the progression of hepatocellular carcinoma and the development of resistance to sorafenib, the standard initial treatment for advanced disease. This randomized, double-blind, phase 3 trial evaluated cabozantinib as compared with placebo in previously treated patients with advanced hepatocellular carcinoma. METHODS: A total of 707 patients were randomly assigned in a 2:1 ratio to receive cabozantinib (60 mg once daily) or matching placebo. Eligible patients had received previous treatment with sorafenib, had disease progression after at least one systemic treatment for hepatocellular carcinoma, and may have received up to two previous systemic regimens for advanced hepatocellular carcinoma. The primary end point was overall survival. Secondary end points were progression-free survival and the objective response rate. RESULTS: At the second planned interim analysis, the trial showed significantly longer overall survival with cabozantinib than with placebo. Median overall survival was 10.2 months with cabozantinib and 8.0 months with placebo (hazard ratio for death, 0.76; 95% confidence interval [CI], 0.63 to 0.92; P=0.005). Median progression-free survival was 5.2 months with cabozantinib and 1.9 months with placebo (hazard ratio for disease progression or death, 0.44; 95% CI, 0.36 to 0.52; P<0.001), and the objective response rates were 4% and less than 1%, respectively (P=0.009). Grade 3 or 4 adverse events occurred in 68% of patients in the cabozantinib group and in 36% in the placebo group. The most common high-grade events were palmar-plantar erythrodysesthesia (17% with cabozantinib vs. 0% with placebo), hypertension (16% vs. 2%), increased aspartate aminotransferase level (12% vs. 7%), fatigue (10% vs. 4%), and diarrhea (10% vs. 2%). CONCLUSIONS: Among patients with previously treated advanced hepatocellular carcinoma, treatment with cabozantinib resulted in longer overall survival and progression-free survival than placebo. The rate of high-grade adverse events in the cabozantinib group was approximately twice that observed in the placebo group. (Funded by Exelixis; CELESTIAL ClinicalTrials.gov number, NCT01908426 .).

High-grade gliomas, including anaplastic oligodendroglioma, represent the most common malignant neoplasms of the central nervous system in the adult. The standard treatment of anaplastic oligodendroglioma consists of maximum surgical resection, radiotherapy and subsequent chemotherapy. Despite multimodal treatment, theoretically, all cases can relapse. Immune checkpoint inhibitors (ICIs) as pembrolizumab demonstrated promising results in many types of tumors, particularly in the presence of mismatch repair deficiency (MMRd). However, no ICI benefit was demonstrated in high-grade glioma prospective studies, although no biomarker was analyzed. Here, we describe an interesting case of recurrent anaplastic oligodendroglioma with MMRd, reporting a prolonged disease stability during pembrolizumab treatment.

PURPOSE: Therapeutic strategies for prostate cancer (PCa) have been evolving dramatically worldwide. The current article reports on the evolution of surgical management strategies for PCa in Italy. METHODS: The data from two independent Italian multicenter projects, the MIRROR-SIU/LUNA (started in 2007, holding data of 890 patients) and the Pros-IT-CNR project (started in 2014, with data of 692 patients), were compared. Differences in patients' characteristics were evaluated. Multivariable logistic regression models were used to identify characteristics associated with robot-assisted (RA) procedure, nerve sparing (NS) approach, and lymph node dissection (LND). RESULTS: The two cohorts did not differ in terms of age and prostate-specific antigen (PSA) levels at biopsy. Patients enrolled in the Pros-IT-CNR project more frequently were submitted to RA (58.8% vs 27.6%, p < 0.001) and NS prostatectomy (58.4% vs. 52.9%, p = 0.04), but received LND less frequently (47.7% vs. 76.7%, p < 0.001), as compared to the MIRROR-SIU/LUNA patients. At multivariate logistic models, Lower Gleason Scores (GS) and PSA levels were significantly associated with RA prostatectomy in both cohorts. As for the MIRROR-SIU/LUNA data, clinical T-stage was a predictor for NS (OR = 0.07 for T3, T4) and LND (OR = 2.41 for T2) procedures. As for Pros-IT CNR data, GS ≥ (4 + 3) and positive cancer cores ≥ 50% were decisive factors both for NS (OR 0.29 and 0.30) and LND (OR 7.53 and 2.31) strategies. CONCLUSIONS: PCa management has changed over the last decade in Italian centers: RA and NS procedures without LND have become the methods of choice to treat newly medium-high risk diagnosed PCa.

OBJECTIVE: Burnout may represent a significant source of distress in health care professionals. Many studies have reported its negative effect on career satisfaction and personal life. The aim of the present study was to investigate the relation between burnout and life satisfaction in a large sample of Italian oncologists. METHODS: An online survey was conducted of 14.5% of the Italian oncologists' population (n = 533) using Copenhagen Burnout Inventory, Satisfaction with Life Scale and additional questions exploring professional and personal factors. Moderated regression analysis was carried out to explore how burnout may relate to life satisfaction. RESULTS: One out of 10 (10.5%) oncologists showed significant burnout symptoms, whereas 1 out of 3 (33.8%) reported being at least slightly dissatisfied with their own life. Family concerns significantly moderated the relationship between burnout and life satisfaction. Men and chiefs of cancer units or departments showed lower rates of burnout and life dissatisfaction than women and other oncologists, respectively. CONCLUSIONS: Reported results are in line with existing data about a limited burnout prevalence in Italian oncologists. We discuss the potential role of gender inequality in explaining our findings. The present study suggests that family concerns may be considered a risk factor for both burnout and life dissatisfaction in oncologists.

PURPOSE: Brain tumor-related epilepsy (BTRE) is frequent in patients affected with glioma. Most patients have refractory seizures and require polytherapy. Promising treatment options derive from the development of novel anti-epileptic drugs (AEDs), like Eslicarbazepine (ESL), whose role in BTRE has not yet been explored. Our aim was to report a retrospective cohort of patients affected by BTRE treated with ESL as an adjunctive therapy and to discuss the potential role of this third-generation AED in this clinical context. METHODS: We analyzed a single-center, retrospectively collected cohort of patients affected by glioma and BTRE, treated with ESL as an adjunctive therapy. RESULTS: Analysis included 5 males and 3 females with age ranging from 37 to 75 years (mean = 55.5). Mean baseline Karnofsky performance status was 87.5 (range 70-100). Patients were affected by diffuse astrocytoma (3), low grade oligodendroglioma (2), anaplastic glioma (2) and glioblastoma (1). Mean follow-up was 19 months (range 6-59). Mean dose at the last follow-up was 950 mg daily. Mean weekly seizures in the month before initiation of ESL numbered 17.6 (range 0.25-50). At the last follow-up, mean weekly seizures were 2.2 (range 0-10), i.e. significantly lower than baseline (p = 0.03). The mean reduction of seizures achieved after introduction of ESL was 65%, with 6/8 patients (75%) showing a reduction of more than 50%. Two patients (25%) were seizure free. CONCLUSIONS: This single-center experience suggests that ESL may be a well-tolerated, efficacious option as an add-on drug in the treatment of BTRE.

BACKGROUND AND AIM: The aim of our retrospective study is to evaluate the prognostic significance of aspirin in patients with advanced HCC treated with sorafenib. METHODS: 304 patients with HCC,consecutively treated with sorafenib from May 2007 to September 2018, were included in the clinical study. Of Them 93 patients token aspirin. Progression-free survival (PFS)and overall survival (OS)were estimated with the Kaplan-Meier method and compared with the log-rank test. RESULTS: The concomitant use of sorafenib and aspirin was associated with a median OS of 18.3 months compared to 8.8 months of patients who did not receive aspirin (HR 0.57; P < 0.0001). The concomitant use of sorafenib and aspirin was associated with a median PFS of 7.3 months compared to 3.0 months of patients who did not receive aspirin (HR 0.61; P = 0.0003). In the multivariate analysis, the use of aspirin maintained an independent prognostic value for OS(HR 0.61; P = 0.0013). In second line the concomitant use of regorafenib and aspirin was associated with a median OS of 16.9 months compared to 8.0 months of patients who did not receive aspirin (HR 0.30; P = 0.02). CONCLUSION: Globally, our data seem to suggest that aspirin use may improve the clinical outcome of patients with advanced hepatocellular carcinoma receiving sorafenib and regorafenib.

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.

The aim of our study was to develop and validate a machine learning algorithm to predict response of individual HER2-amplified colorectal cancer liver metastases (lmCRC) undergoing dual HER2-targeted therapy. Twenty-four radiomics features were extracted after 3D manual segmentation of 141 lmCRC on pretreatment portal CT scans of a cohort including 38 HER2-amplified patients; feature selection was then performed using genetic algorithms. lmCRC were classified as nonresponders (R-), if their largest diameter increased more than 10% at a CT scan performed after 3 months of treatment, responders (R+) otherwise. Sensitivity, specificity, negative (NPV) and positive (PPV) predictive values in correctly classifying individual lesion and overall patient response were assessed on a training dataset and then validated on a second dataset using a Gaussian naïve Bayesian classifier. Per-lesion sensitivity, specificity, NPV and PPV were 89%, 85%, 93%, 78% and 90%, 42%, 73%, 71% respectively in the testing and validation datasets. Per-patient sensitivity and specificity were 92% and 86%. Heterogeneous response was observed in 9 of 38 patients (24%). Five of nine patients were carriers of nonresponder lesions correctly classified as such by our radiomics signature, including four of seven harboring only one nonresponder lesion. The developed method has been proven effective in predicting behavior of individual metastases to targeted treatment in a cohort of HER2 amplified patients. The model accurately detects responder lesions and identifies nonresponder lesions in patients with heterogeneous response, potentially paving the way to multimodal treatment in selected patients. Further validation will be needed to confirm our findings.

BACKGROUND: Immunotherapy with immune checkpoint inhibitors (ICIs) is highly effective in microsatellite instability-high (MSI-H) metastatic colorectal cancer (mCRC); however, specific predictive biomarkers are lacking. PATIENTS AND METHODS: Data and samples from 85 patients with MSI-H mCRC treated with ICIs were gathered. Tumor infiltrating lymphocytes (TILs) and tumor mutational burden (TMB) were analyzed in an exploratory cohort of "super" responders and "clearly" refractory patients; TILs were then evaluated in the whole cohort of patients. Primary objectives were the correlation between the number of TILs and TMB and their role as biomarkers of ICI efficacy. Main endpoints included response rate (RR), progression-free survival (PFS), and overall survival (OS). RESULTS: In the exploratory cohort, an increasing number of TILs correlated to higher TMB (Pearson's test, p = .0429). In the whole cohort, median number of TILs was 3.6 in responders compared with 1.8 in nonresponders (Mann-Whitney test, p = .0448). RR was 70.6% in patients with high number of TILs (TILs-H) compared with 42.9% in patients with low number of TILs (odds ratio = 3.20, p = .0291). Survival outcomes differed significantly in favor of TILs-H (PFS: hazard ratio [HR] = 0.42, p = .0278; OS: HR = 0.41, p = .0463). CONCLUSION: A significant correlation between higher TMB and increased number of TILs was shown. A significantly higher activity and better PFS and OS with ICI in MSI-H mCRC were reported in cases with high number of TILs, thus supporting further studies of TIL count as predictive biomarker of ICI efficacy. IMPLICATIONS FOR PRACTICE: Microsatellite instability is the result of mismatch repair protein deficiency, caused by germline mutations or somatic modifications in mismatch repair genes. In metastatic colorectal cancer (mCRC), immunotherapy (with immune checkpoint inhibitors [ICIs]) demonstrated remarkable clinical benefit in microsatellite instability-high (MSI-H) patients. ICI primary resistance has been observed in approximately 25% of patients with MSI-H mCRC, underlining the need for predictive biomarkers. In this study, tumor mutational burden (TMB) and tumor infiltrating lymphocyte (TIL) analyses were performed in an exploratory cohort of patients with MSI-H mCRC treated with ICIs, demonstrating a significant correlation between higher TMB and increased number of TILs. Results also demonstrated a significant correlation between high number of TILs and clinical responses and survival benefit in a large data set of patients with MSI-H mCRC treated with ICI. TMB and TILs could represent predictive biomarkers of ICI efficacy in MSI-H mCRC and should be incorporated in future trials testing checkpoint inhibitors in colorectal cancer.

Secreting pituitary adenomas are tumors for which few treatment options are available, including surgical treatment and management of hormonal imbalance due to altered pituitary secretion. In case of inoperable relapse, radiotherapy or chemotherapeutic treatment can be considered; the effectiveness of these treatments, however, remains limited. In the immunotherapy era, it is necessary to select patients who can benefit from immunotherapeutic treatment. Mismatch repair deficiency is strongly associated with responsiveness to anti-PD-1 in other cancers and can be detected using immunohistochemistry for MLH1, MSH2, MHS6, and PMS2. In this case report, we report a case of rapid disease progression to pembrolizumab in a patient with a MMRd pituitary adrenocorticotropic hormone (ACTH)-secreting adenoma. For the best of our knowledge, we described for the first time, a poor efficacy of pembrolizumab in a patient with ACTH-secreting pituitary adenoma having mismatch repair deficiency probably caused by high levels of cortisol in this patient. Prospective study should be performed to assess the activity of immune checkpoint inhibitor alone or in association with temozolomide in this subsetting of pituitary adenomas.

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.

BACKGROUND: DNA mismatch repair (MMR) is a system for repairing errors in DNA replication. Cancer cells with MMR deficiency can have immunohistochemical loss of MMR protein expression leading to a hypermutable phenotype that may correlate with anti-PD1 efficacy. Scant data exist about immunohistochemical loss of MMR protein expression in high-grade gliomas (HGG). MATERIALS AND METHODS: We performed a large multicenter retrospective study to investigate the frequency and the prognostic role of immunohistochemical loss of MMR protein expression in HGG patients; we nevertheless evaluated the association between this status and clinical or molecular characteristics. Immunohistochemical loss of MMR protein expression was recorded as partial or complete loss of at least 1 MMR protein. RESULTS: We analyzed the expression of MMR proteins in tumor tissue of 355 consecutive patients. Partial and complete immunohistochemical loss of MMR proteins was found in 43/355 samples (12.1%) and among these, 15 cases (4.2%) showed a complete loss of at the least one MMR protein. Alteration of MSH2 expression was found in 55.8%, MSH6 in 46.5%, PMS2 in 34.9%, and MLH1 in 30.2%. Alteration of MMR protein expression was statistically more frequent in anaplastic gliomas, in recurrent disease, in patients treated with temozolomide, and in IDH-mut gliomas. Immunohistochemical loss of MMR proteins was not associated with survival, adjusting for clinically relevant confounders. CONCLUSIONS: MMR protein expression status did not affect survival in HGG patients. We identified clinical and molecular characteristics correlating with immunohistochemical loss of MMR proteins expression. A large study should be performed to analyze its predictive role of immune checkpoint inhibitor efficacy in these subgroups of patients.

BACKGROUND: Glioblastoma is a highly vascularised tumour and there are few treatment options after disease recurrence. Regorafenib is an oral multikinase inhibitor of angiogenic, stromal, and oncogenic receptor tyrosine kinases. We aimed to assess the efficacy and safety of regorafenib in the treatment of recurrent glioblastoma. METHODS: REGOMA is a randomised, multicentre, open-label phase 2 trial done in ten centres in Italy. Eligible patients (aged ≥18 years) with histologically confirmed glioblastoma, Eastern Cooperative Oncology Group performance status 0 or 1, and documented disease progression after surgery followed by radiotherapy and temozolomide chemoradiotherapy were randomly assigned (1:1) by a web-based system, stratified by centre and surgery at recurrence (yes vs no), to receive regorafenib 160 mg once daily for the first 3 weeks of each 4-week cycle or lomustine 110 mg/m2 once every 6 weeks until disease progression, death, unacceptable toxicity, or consent withdrawal. The primary endpoint was overall survival in the intention-to-treat population. This trial is registered with ClinicalTrials.gov, NCT02926222, and is currently in follow-up. FINDINGS: Between Nov 27, 2015, and Feb 23, 2017, 124 patients were screened and 119 eligible patients were randomly assigned to receive regorafenib (n=59) or lomustine (n=60). Median follow-up was 15·4 months (IQR 13·8-18·1). At the analysis cutoff date, 99 (83%) of 119 patients had died: 42 (71%) of 59 in the regorafenib group and 57 (95%) of 60 in the lomustine group. Overall survival was significantly improved in the regorafenib group compared with the lomustine group, with a median overall survival of 7·4 months (95% CI 5·8-12·0) in the regorafenib group and 5·6 months (4·7-7·3) in the lomustine group (hazard ratio 0·50, 95% CI 0·33-0·75; log-rank p=0·0009). Grade 3-4 treatment-related adverse events occurred in 33 (56%) of 59 patients treated with regorafenib and 24 (40%) of 60 with lomustine. The most frequent grade 3 or 4 adverse events related to regorafenib were hand-foot skin reaction, increased lipase, and blood bilirubin increased (in six [10%] of 59 patients each). In the lomustine group, the most common grade 3 or 4 adverse events were decreased platelet count (eight [13%] of 60 patients), decreased lymphocyte count (eight [13%]), and neutropenia (seven [12%]). No death was considered by the investigators to be drug related. INTERPRETATION: REGOMA showed an encouraging overall survival benefit of regorafenib in recurrent glioblastoma. This drug might be a new potential treatment for these patients and should be investigated in an adequately powered phase 3 study. FUNDING: Veneto Institute of Oncology and Bayer Italy.
