Durvalumab and tremelimumab plus local partial tumour ablation (radiofrequency ablation or stereotactic radiotherapy) in patients with unresectable liver metastases from metastatic colorectal cancer: results of the EORTC-1560-GITCG multicentre, single-arm phase II study (ILOC).

Background: Treatment strategies for metastatic colorectal cancer (mCRC) patients with unresectable liver metastases include systemic therapy and local ablative treatments (LATs). While immunotherapy outcomes in patients with microsatellite stable mCRC have been disappointing, LATs may induce local immune activation and potentially prime the tumour microenvironment for a systemic immunotherapy response. This study investigates the combination of partial liver ablation with tremelimumab and durvalumab to induce responses in unablated liver metastases.

Intra-Arterial Drug Delivery of Both a Small and Large Molecule Theranostic Radiotracer Probe into an Orthotopic OncoPIG Liver Tumor Model After Pseudovascular Isolation.

Purpose: Directed therapies employing small (SM) and large (LM) molecule drugs to target tumor antigens are used for treatment. Theranostics radiolabels them for imaging and radiation treatment. Poor radiopharmaceutical kinetics, prolonged circulating times, and high nontarget radiation to normal tissues after intravenous (i.

Dose adaptation to compensate for cumulative intra-fraction motion effects in online adaptive radiotherapy.

The objective of this work was to investigate the feasibility of using 0 mm PTV margin in online adaptive radiotherapy for the first fractions, in combination with treatment-specific local compensation of accumulated underdosage to the target in the last fraction.Intrafraction motion patterns and delineations of twelve patients with prostate cancer were selected to cover a range of observed systematic and random inter- and intrafraction motion patterns. Treatment plans with 0 and 3 mm margins were created and dose was accumulated rigidly using the observed motion patterns.

Acute pulmonary embolism treatment in lung transplant recipients: mechanical thrombectomy and catheter directed thrombolysis.

Purpose: Acute pulmonary embolism (PE) presents a significant challenge in lung transplant recipients (LTR), even with prophylactic anticoagulation. Due to the heightened risk of complications in this population, the optimal treatment approach for acute PE remains uncertain. This retrospective case series aims to elucidate the outcomes of percutaneous mechanical thrombectomy with the Inari device (MT) and catheter-directed thrombolysis (CDT) in managing acute PE in lung transplant patients.

Local and systemic biodistribution of a small-molecule radiopharmaceutical probe after transcatheter embolization and intra-arterial delivery in a porcine orthotopic renal tumor model.

Background: Small-molecule biomacromolecules target tumor-specific antigens. They are employed as theranostic agents for imaging and treatment. Intravenous small-molecule radioligands exhibit rapid tumor uptake and excretion.

Transcatheter pseudo-vascular isolation for localization and concentration of a large molecule theranostic probe into a transgenic OncoPIG kidney tumor.

Introduction: Great strides have been made identifying molecular and genetic changes expressed by various tumor types. These molecular and genetic changes are used as pharmacologic targets for precision treatment using large molecule (LM) proteins with high specificity. Theranostics exploits these LM biomolecules via radiochemistry, creating sensitive diagnostic and therapeutic agents.

Long-Term Follow-Up of the Response-Adapted Intergroup EORTC/LYSA/FIL H10 Trial for Localized Hodgkin Lymphoma.

JCO The primary analysis of the Early positron emission tomography (ePET) Response-Adapted Treatment in localized Hodgkin Lymphoma H10 Trial demonstrated that in ePET-negative patients, the risk of relapse increased when involved-node radiotherapy (INRT) was omitted and that in ePET-positive patients, switching from doxorubicin, bleomycin, vinblastine, and dacarbazine (ABVD) to bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine, and prednisone (BEACOPPesc) significantly improved 5-year progression-free survival (PFS). Here, we report the final results of a preplanned analysis at a 10-year follow-up. In the favorable (F) ePET-negative group, the 10-year PFS rates were 98.

Designing clinical trials based on modern imaging and metastasis-directed treatments in patients with oligometastatic breast cancer: a consensus recommendation from the EORTC Imaging and Breast Cancer Groups.

Breast cancer remains the most common cause of cancer death among women. Despite its considerable histological and molecular heterogeneity, those characteristics are not distinguished in most definitions of oligometastatic disease and clinical trials of oligometastatic breast cancer. After an exhaustive review of the literature covering all aspects of oligometastatic breast cancer, 35 experts from the European Organisation for Research and Treatment of Cancer Imaging and Breast Cancer Groups elaborated a Delphi questionnaire aimed at offering consensus recommendations, including oligometastatic breast cancer definition, optimal diagnostic pathways, and clinical trials required to evaluate the effect of diagnostic imaging strategies and metastasis-directed therapies.

Efficacy and safety of nivolumab for patients with pre-treated type B3 thymoma and thymic carcinoma: results from the EORTC-ETOP NIVOTHYM phase II trial.

Background: Thymic malignancies are rare intrathoracic tumors, which may be aggressive and difficult to treat. They represent a therapeutic challenge in the advanced/metastatic setting, with limited treatment options after the failure of first-line platinum-based chemotherapy. They are frequently associated with autoimmune disorders that also impact oncological management.

Guidelines for the definition of time-to-event end points in renal cell cancer clinical trials: results of the DATECAN project†.

Background: In clinical trials, the use of intermediate time-to-event end points (TEEs) is increasingly common, yet their choice and definitions are not standardized. This limits the usefulness for comparing treatment effects between studies. The aim of the DATECAN Kidney project is to clarify and recommend definitions of TEE in renal cell cancer (RCC) through a formal consensus method for end point definitions.

Local treatment of pulmonary metastases: from open resection to minimally invasive approach? Less morbidity, comparable local control.

Background: The level of evidence for efficacy of local treatment of pulmonary metastases is low; therefore, complication rates should be minimized. Minimally invasive techniques may have the potential to reduce morbidity but potentially lead to more local and/or ipsilateral recurrences. The objective of this study was to evaluate the introduction of a new treatment strategy incorporating the increased use of video-assisted thoracic surgery (VATS) and radiofrequency ablation (RFA), weighing complications against recurrence rates.

Oligoclonal peripheral T-cell lymphocytosis as a result of aberrant T-cell development in a cortical thymoma.

A 42-year-old man presented with a locally invasive cortical thymoma. Before chemotherapy was commenced 36 months after presentation, an unusual peripheral lymphocytosis of 19 x 10(9)/l had slowly developed over time. After the first course of chemotherapy, the lymphocytosis showed a sharp decline to normal absolute cell numbers and subsequently remained at normal levels.
