    A comprehensive geriatric assessment systematically collects information on geriatric conditions and is propagated in oncology as a useful tool when assessing older cancer patients. The objectives were: (a) to study the prevalence of geriatric conditions in cancer patients aged ≥ 65 years, acutely admitted to a general medicine ward; (b) to determine functional decline and mortality within 12 months after admission; and (c) to assess which geriatric conditions and cancer-related variables are associated with 12-month mortality. This was an observational cohort study of 292 cancer patients aged ≥ 65 years, acutely admitted to the general medicine and oncology wards of two university hospitals and one secondary teaching hospital. Baseline assessments included patient characteristics, reason for admission, comorbidity, and geriatric conditions. Follow-up at 3 and 12 months was aimed at functional decline (loss of one or more activities of daily living [ADL]) and mortality. The median patient age was 74.9 years, and 95% lived independently; 126 patients (43%) had metastatic disease. A high prevalence of geriatric conditions was found for instrumental ADL impairment (78%), depressive symptoms (65%), pain (65%), impaired mobility (48%), malnutrition (46%), and ADL impairment (38%). Functional decline was observed in 8% and 33% of patients at 3 and 12 months, respectively. Mortality rates were 38% at 3 months and 64% at 12 months. Mortality was associated with cancer-related factors only. In these acutely hospitalized older cancer patients, mortality was only associated with cancer-related factors. The prevalence of geriatric conditions in this population was high. Future research is needed to elucidate if addressing these conditions can improve quality of lif

    Low and variable tumor reactivity of the intratumoral TCR repertoire in human cancers

    Infiltration of human cancers by T cells is generally interpreted as a sign of immune recognition, and there is a growing effort to reactivate dysfunctional T cells at such tumor sites1. However, these efforts only have value if the intratumoral T cell receptor (TCR) repertoire of such cells is intrinsically tumor reactive, and this has not been established in an unbiased manner for most human cancers. To address this issue, we analyzed the intrinsic tumor reactivity of the intratumoral TCR repertoire of CD8+ T cells in ovarian and colorectal cancer—two tumor types for which T cell infiltrates form a positive prognostic marker2,3. Data obtained demonstrate that a capacity to recognize autologous tumor is limited to approximately 10% of intratumoral CD8+ T cells. Furthermore, in two of four patient samples tested, no tumor-reactive TCRs were identified, despite infiltration of their tumors by T cells. These data indicate that the intrinsic capacity of intratumoral T cells to recognize adjacent tumor tissue can be rare and variable, and suggest that clinical efforts to reactivate intratumoral T cells will benefit from approaches that simultaneously increase the quality of the intratumoral TCR repertoire

    BACKGROUND: Leiomyosarcoma is an aggressive soft tissue sarcoma with a 5-year survival rate of 15 to 60%. Treatment options for inoperable or metastatic patients are limited owing to frequent resistance of tumours to chemotherapy and radiation. In this study, we hypothesised that antiapoptotic Bcl-2 family proteins might contribute to leiomyosarcoma chemoresistance and therefore inhibition of Bcl-2 family proteins might sensitise leiomyosarcomas to conventional chemotherapy. METHODS: Expression of the Bcl-2 family proteins Bcl-xL, Bcl-w and Bcl-2 was investigated using immunohistochemistry on a tissue microarray containing 43 leiomyosarcomas. Furthermore, we investigated whether ABT-737, a potent BH3 mimetic, sensitises leiomyosarcoma cells to doxorubicin treatment in vitro. RESULTS: Seventy-seven per cent, 84% and 42% of leiomyosarcomas demonstrated high expression of Bcl-2, Bcl-xL and Bcl-w, respectively. Single-agent treatment with ABT-737 resulted in a minor reduction of cell viability. However, combination treatment of ABT-737 and doxorubicin revealed synergism in all four cell lines, by inducing apoptosis. CONCLUSIONS: In conclusion, Bcl-2 family proteins contribute to soft tissue leiomyosarcoma chemoresistance. Antiapoptotic proteins are highly expressed in leiomyosarcoma of soft tissue, and inhibition of these proteins using a BH3 mimetic increases leiomyosarcoma sensitivity to doxorubicin

    Vaccination guidelines for patients treated for hematological diseases are typically conservative. Given their high risk for severe coronavirus infectious disease 2019 (COVID-19) it is important to identify those patients that benefit from vaccination. We prospectively quantified serum IgG antibodies to spike subunit 1 (S1)antigensduring and after 2-dose mRNA-1273 (Spikevax/Moderna) vaccination in hematology patients. Obtaining S1 IgG≥300 binding antibody units (BAU)/mlwas considered adequate as it represents the lower level of S1 IgG concentration obtained in healthy individuals andit correlates with potent virus neutralization. Selected patients (n=723) were severely immunocompromised due to their disease or treatment thereof. Nevertheless, more than 50% of patients obtained S1 IgG ≥300 BAU/ml after 2-dose mRNA-1273. All patients with sickle cell disease or chronic myeloid leukemia obtained adequate antibody concentrations.Around 70% ofpatients with chronic graftversushostdisease (GvHD), multiple myeloma, or untreated chronic lymphocytic leukemia (CLL) obtained S1 IgG≥300 BAU/ml.Ruxolitinib or hypomethylating therapy but not high-dose chemotherapy blunted responses in myeloid malignancies. Responses inlymphoma patients, CLL patients on ibrutinib, and chimeric antigen receptor T cell recipients were low.The minimal time-interval after autologous hematopoietic cell transplantation (HCT) to reach adequate concentrations was <2 months for multiple myeloma, 8 months for lymphoma, and 4-6 months after allogeneic HCT.Serum IgG4, absolute B and NK cell number and number of immunosuppressants predicted S1 IgG ≥300 BAU/ml. Hematology patients on chemotherapy, shortly after HCT, or with chronic GvHD should not be precluded from vaccination. Netherlands Trial Register NL9553

    There is insufficient knowledge on intermediate-term survival of non-metastatic muscle-invasive bladder cancer (MIBC) after open (ORC) versus robot-assisted (RARC) cystectomy, with or without neo-adjuvant chemotherapy (NAC). This retrospective study was performed in 19 Dutch hospitals between 2012 and 2015 to assess the five-year survival after both interventions and the influence of NAC. Out of 1,534 cT1-4N0-1-patients, 1,086 patients were treated with ORC and 389 with RARC. The 5-year survival rate after ORC was 51% (95% CI 47–53) versus 58% after RARC (95% CI 52–63), hazard ratio 1.00 (95% CI 0.84–1.20) after multivariable analysis. 226 of 965 cT2-4aN0 patients were treated with NAC. More patients had ypT0 after NAC than after no NAC (31% vs 15%; p?&lt; 0.01). The best five-year survival was in patients with ypT0 after NAC (89%; 95% CI 81–97). This study shows similar five-year survival of MIBC patients treated with ORC or RARC and shows that the best survival was after NAC

    Fourth mRNA COVID-19 vaccination in immunocompromised patients with haematological malignancies (COBRA KAI): a cohort studyResearch in context

    Summary: Background: Patients with haematological malignancies have impaired antibody responses to SARS-CoV-2 vaccination. We aimed to investigate whether a fourth mRNA COVID-19 vaccination improved antibody quantity and quality. Methods: In this cohort study, conducted at 5 sites in the Netherlands, we compared antibody concentrations 28 days after 4 mRNA vaccinations (3-dose primary series plus 1 booster vaccination) in SARS-CoV-2 naive, immunocompromised patients with haematological malignancies to those obtained by age-matched, healthy individuals who had received the standard primary 2-dose mRNA vaccination schedule followed by a first booster mRNA vaccination. Prior to and 4 weeks after each vaccination, peripheral blood samples and data on demographic parameters and medical history were collected. Concentrations of antibodies that bind spike 1 (S1) and nucleocapsid (N) protein of SARS-CoV-2 were quantified in binding antibody units (BAU) per mL according to the WHO International Standard for COVID-19 serological tests. Seroconversion was defined as an S1 IgG concentration >10 BAU/mL and a previous SARS-CoV-2 infection as N IgG >14.3 BAU/mL. Antibody neutralising activity was tested using lentiviral-based pseudoviruses expressing spike protein of SARS-CoV-2 wild-type (D614G), Omicron BA.1, and Omicron BA.4/5 variants. This study is registered with EudraCT, number 2021-001072-41. Findings: Between March 24, 2021 and May 4, 2021, 723 patients with haematological diseases were enrolled, of which 414 fulfilled the inclusion criteria for the current analysis. Although S1 IgG concentrations in patients significantly improved after the fourth dose, they remained significantly lower compared to those obtained by 58 age-matched healthy individuals after their first booster (third) vaccination. The rise in neutralising antibody concentration was most prominent in patients with a recovering B cell compartment, although potent responses were also observed in patients with persistent immunodeficiencies. 19% of patients never seroconverted, despite 4 vaccinations. Patients who received their first 2 vaccinations when they were B cell depleted and the third and fourth vaccination during B cell recovery demonstrated similar antibody induction dynamics as patients with normal B cell numbers during the first 2 vaccinations. However, the neutralising capacity of these antibodies was significantly better than that of patients with normal B cell numbers after two vaccinations. Interpretation: A fourth mRNA COVID-19 vaccination improved S1 IgG concentrations in the majority of patients with a haematological malignancy. Vaccination during B cell depletion may pave the way for better quality of antibody responses after B cell reconstitution.
