Phase 2 Study of Pomalidomide (CC-4047) Monotherapy for Children and Young Adults With Recurrent or Progressive Primary Brain Tumors.

Introduction: Treatment of recurrent primary pediatric brain tumors remains a major challenge, with most children succumbing to their disease. We conducted a prospective phase 2 study investigating the safety and efficacy of pomalidomide (POM) in children and young adults with recurrent and progressive primary brain tumors.

Methods: Patients with recurrent and progressive high-grade glioma (HGG), diffuse intrinsic pontine glioma (DIPG), ependymoma, or medulloblastoma received POM 2.

Epithelioid hemangioendothelioma, an ultra-rare cancer: a consensus paper from the community of experts.

Epithelioid hemangioendothelioma (EHE) is an ultra-rare, translocated, vascular sarcoma. EHE clinical behavior is variable, ranging from that of a low-grade malignancy to that of a high-grade sarcoma and it is marked by a high propensity for systemic involvement. No active systemic agents are currently approved specifically for EHE, which is typically refractory to the antitumor drugs used in sarcomas.

Real-world treatment outcomes with brigatinib in patients with pretreated ALK+ metastatic non-small cell lung cancer.

Background: The next-generation ALK inhibitor brigatinib is approved for use in patients with ALK inhibitor-naïve ALK-positive advanced NSCLC and in patients previously treated with crizotinib. A phase II trial showed that brigatinib is active in patients with ALK-positive metastatic NSCLC (mNSCLC) who had progressed on prior crizotinib (response rate 56 %, median PFS 16.7 months, median OS 34.

Phase 1 study of the ATR inhibitor berzosertib in combination with cisplatin in patients with advanced solid tumours.

Background: Berzosertib (formerly M6620, VX-970) is a highly potent and selective, first-in-class ataxia telangiectasia-mutated and Rad3-related protein kinase (ATR) inhibitor. We assessed the safety, tolerability, pharmacokinetics, and preliminary efficacy of berzosertib plus cisplatin.

Methods: Adult patients with advanced solid tumours refractory or resistant to standard of care therapies received ascending doses of cisplatin (day 1) and berzosertib (days 2 and 9) every 3 weeks (Q3W).

Updates and Ongoing Challenges in Imaging of Multiple Myeloma: Expert Panel Narrative Review.

Advances in the understanding and treatment of multiple myeloma have led to the need for more sensitive and accurate imaging of intramedullary and extramedullary disease. This role of imaging is underscored by recently revised imaging recommendations of the International Myeloma Working Group (IMWG). This narrative review discusses these recommendations from the IMWG for different disease stages, focusing on advanced whole-body modalities, and addresses related challenges and controversies.

Association of Bone Metastatic Burden With Survival Benefit From Prostate Radiotherapy in Patients With Newly Diagnosed Metastatic Prostate Cancer: A Secondary Analysis of a Randomized Clinical Trial.

Importance: Prostate radiotherapy (RT) improves survival in men with low-burden metastatic prostate cancer. However, owing to the dichotomized nature of metastatic burden criteria, it is not clear how this benefit varies with bone metastasis counts and metastatic site.

Objective: To evaluate the association of bone metastasis count and location with survival benefit from prostate RT.

A simple digital image analysis system for automated Ki67 assessment in primary breast cancer.

Aims: Ki67 is a well-established immunohistochemical marker associated with cell proliferation that has prognostic and predictive value in breast cancer. Quantitative evaluation of Ki67 is traditionally performed by assessing stained tissue slides with light microscopy. Automated image analysis systems have become available and, if validated, could provide greater standardisation and improved precision of Ki67 scoring.

Long-term multicentre experience of adjuvant radiotherapy for pN3 squamous cell carcinoma of the penis.

Objective: To present the long-term adjuvant radiotherapy outcomes of patients with pN3 squamous cell carcinoma of the penis (SCCp) treated at two UK centres.

Patients And Methods: We conducted a retrospective audit of all pN3 SCCp patients, deemed suitable for adjuvant therapy by a specialist multidisciplinary team at St George's and Leeds Hospitals, who received adjuvant radiotherapy. Primary outcomes were recurrence-free survival (RFS), cancer-specific survival (CSS) and overall survival (OS).

Hairy Cell Leukaemia: From Hairy Beginnings to a BRAF New World.

For a disease initially described in 1958 as a leukaemic reticulo-endotheliosis associated with poor outcomes, we have come a long way in our understanding of Hairy cell leukaemia. The vast majority of patients diagnosed with this rare, often diagnostically challenging, leukaemia can now expect a lifespan that is similar to the general population. This article covers some of the highlights from the last 6 decades that have led to our current understanding of this fascinating leukaemia - from elucidation of its B-cell origin to discovery of the almost universal occurrence of the BRAF V600E mutation; from the initial successes reported with splenectomy to the more recent development of targeted therapies such as Vemurafenib and Moxetumomab Pasudotox.

The Automated Bone Scan Index as a Predictor of Response to Prostate Radiotherapy in Men with Newly Diagnosed Metastatic Prostate Cancer: An Exploratory Analysis of STAMPEDE's "M1|RT Comparison".

Background: Prostate radiotherapy (RT) is a first-line option for newly diagnosed men with low-burden metastatic prostate cancer. The current criterion to define this clinical state is based on manual bone metastasis counts, but enumeration of bone metastases is limited by interobserver variations, and it does not account for metastasis volume or lesional coalescence. The automated bone scan index (aBSI) is a quantitative method of evaluating bone metastatic burden in a standardised and reproducible manner.

Daily adaptive radiotherapy for patients with prostate cancer using a high field MR-linac: Initial clinical experiences and assessment of delivered doses compared to a C-arm linac.

Introduction: MR-guided adapted radiotherapy (MRgART) using a high field MR-linac has recently become available. We report the estimated delivered fractional dose of the first five prostate cancer patients treated at our centre using MRgART and compare this to C-Arm linac daily Image Guided Radiotherapy (IGRT).

Methods: Patients were treated using adapted treatment plans shaped to their daily anatomy.

Radiological Patterns of Drug-induced Interstitial Lung Disease (DILD) in Early-phase Oncology Clinical Trials.

Purpose: Drug-induced interstitial lung disease (DILD) is a rare, but potentially fatal toxicity. Clinical and radiological features of DILD in the early experimental setting are poorly described.

Patients And Methods: A total of 2,499 consecutive patients with advanced cancer on phase I clinical trials were included.

Hairy Cell Leukaemia.

Purpose Of Review: To summarise diagnostic clinical/laboratory findings and highlight differences between classical hairy cell leukaemia (HCLc) and hairy cell leukaemia variant (HCLv). Discussion of prognosis and current treatment indications including novel therapies, linked to understanding of the underlying molecular pathogenesis.

Recent Findings: Improved understanding of the underlying pathogenesis of HCLc, particularly the causative mutation BRAF V600E, leading to constitutive activation of the MEK/ERK signalling pathway and increased cell proliferation.

Pembrolizumab in paediatric patients with advanced melanoma or a PD-L1-positive, advanced, relapsed, or refractory solid tumour or lymphoma (KEYNOTE-051): interim analysis of an open-label, single-arm, phase 1-2 trial.

Background: Pembrolizumab is approved for the treatment of advanced cancer in adults; however, no information is available on safety and efficacy in paediatric patients. We aimed to establish the recommended phase 2 dose of pembrolizumab and its safety and antitumour activity in advanced paediatric cancer.

Methods: KEYNOTE-051 is an ongoing phase 1-2 open-label trial.

B and T cell prolymphocytic leukaemia.

Prolymphocytic leukaemias B-PLL and T-PLL are rare disorders, typically with an aggressive clinical course and poor prognosis. Combining morphology, immunophenotyping, cytogenetic and molecular diagnostics reliably separates B-PLL and T-PLL from one another and other disorders. In T-PLL discovery of frequent mutations in the JAK-STAT pathway have increased understanding of disease pathogenesis.

Consensus report from the 8th International Forum for Liver Magnetic Resonance Imaging.

Objectives: The 8th International Forum for Liver Magnetic Resonance Imaging (MRI), held in Basel, Switzerland, in October 2017, brought together clinical and academic radiologists from around the world to discuss developments in and reach consensus on key issues in the field of gadoxetic acid-enhanced liver MRI since the previous Forum held in 2013.

Methods: Two main themes in liver MRI were considered in detail at the Forum: the use of gadoxetic acid for contrast-enhanced MRI in patients with liver cirrhosis and the technical performance of gadoxetic acid-enhanced liver MRI, both opportunities and challenges. This article summarises the expert presentations and the delegate voting on consensus statements discussed at the Forum.

Radiotherapy in the Management of Childhood Rhabdomyosarcoma.

Rhabdomyosarcoma is the most common soft-tissue sarcoma of childhood, comprising over 50% of cases. It is considered to be an embryonal tumour of skeletal muscle cell origin, frequently occurring at genitourinary and head and neck sites, although it can arise throughout the body and at sites where there is no skeletal muscle. For most cases, multimodality therapy is required to achieve the best results, incorporating induction ifosfamide, vincristine and actinomycin D-based chemotherapy and local therapy (radiotherapy and/or surgery).

Surveillance of HPV-Positive Head and Neck Squamous Cell Carcinoma with Circulating and Salivary DNA Biomarkers.

Head and neck squamous cell carcinoma (HNSCC) manifests in the mucosal epithelial lining of the oral cavity, oropharynx, hypopharynx, nasopharynx or larynx and has a tremendous disease burden worldwide. Smoking and alcohol consumption were once major risk factors, but HPV-associated infection has emerged as the major contributor to HNSCC occurrence in developed countries. Circulating biomarker evaluations in biofluids, also known as liquid biopsy, are an attractive alternative for cancer screening as they are minimally invasive, potentially low cost, and easily repeatable on a serial basis.

Surgical management of metastatic gastrointestinal stromal tumour.

Background: Gastrointestinal stomal tumours (GISTs) are the most frequently diagnosed mesenchymal tumour of the gastrointestinal tract. The response of most GISTs to tyrosine kinase inhibitor (TKIs) treatment is spectacular; however progression and/or secondary resistance inevitably occurs with long-term treatment of recurrent or metastatic disease. Randomised studies investigating the potential additive benefit of metastasectomy in addition to TKI treatment unfortunately failed to accrue sufficient patients.

Managing Nonmetastatic Castration-resistant Prostate Cancer.

Context: Patients with nonmetastatic castration-resistant prostate cancer (nmCRPC) have rising prostate-specific antigen (PSA) and castrate testosterone levels, with no radiological findings of metastatic disease on computed tomography and bone scan. Given recent drug approvals for nmCRPC, with many other therapeutics and imaging modalities being developed, management of nmCRPC is a rapidly evolving field that merits detailed investigation.

Objective: To review current nmCRPC management practices and identify opportunities for improving care of nmCRPC patients.

Next Generation Cancer Vaccines-Make It Personal!

Dramatic success in cancer immunotherapy has been achieved over the last decade with the introduction of checkpoint inhibitors, leading to response rates higher than with chemotherapy in certain cancer types. These responses are often restricted to cancers that have a high mutational burden and show pre-existing T-cell infiltrates. Despite extensive efforts, therapeutic vaccines have been mostly unsuccessful in the clinic.

Detection of circulating tumour cell clusters in human glioblastoma.

Human glioblastoma (GBM) is a highly aggressive, invasive and hypervascularised malignant brain cancer. Individual circulating tumour cells (CTCs) are sporadically found in GBM patients, yet it is unclear whether multicellular CTC clusters are generated in this disease and whether they can bypass the physical hurdle of the blood-brain barrier.  Here, we assessed CTC presence and composition at multiple time points in 13 patients with progressing GBM during an open-label phase 1/2a study with the microtubule inhibitor BAL101553.
