Wild-type status of KRAS and the NRAS gene (exon 2, 3, and 4) in the tumor should be determined before treatment of metastatic colorectal cancer (mCRC) patients with EGFR-targeting agents. There is a large variation in test methods to determine RAS status, and more sensitive detection methods were recently introduced. Data from quality assessment programs indicate substantial error rates. This study assessed the completeness and correctness of RAS testing in European laboratories that successfully passed external quality assessment (EQA)...

IMPORTANCE: Significant variation in the number and types of oncologists that provide breast cancer follow-up exists. However, there is limited understanding regarding breast cancer survivors' preferences for who provides their follow-up. Our objective was to explore breast cancer survivors' perspectives on the goals of breast cancer follow-up, the preferred role for primary care providers, and the perceived roles of different types of oncologists during follow-up. METHODS: A convenience sample of stage 0-III breast cancer survivors was identified and in-depth one-on-one interviews conducted...

Insufficient chemotherapy response and rapid disease progression remain concerns for small-cell lung cancer (SCLC). Oncologists rely on serial CT scanning to guide treatment decisions, but this cannot assess in vivo target engagement of therapeutic agents. Biomarker assessments in biopsy material do not assess contemporaneous target expression, intratumoral drug exposure, or drug-target engagement. Here, we report the use of PARP1/2-targeted imaging to measure target engagement of PARP inhibitors in vivo. Using a panel of clinical PARP inhibitors, we show that PARP imaging can quantify target engagement of chemically diverse small molecule inhibitors in vitro and in vivo...

Even in 21st century, >90% cancer-associated deaths are caused by metastatic disease. Circulating tumor cells (CTCs), which circulate in the blood stream after release from primary tumors, extravasate and form fatal metastases in different organs. Several clinical trials indicate that CTCs can be used as a liquid biopsy of tumors for early diagnosis of cancers. Since CTCs are extremely rare and exhibit heterogeneous biology due to epithelial-mesenchymal transition (EMT), oncologists continue to face enormous challenges in using CTCs as a true "liquid biopsy" for cancer patients...

REVIEW
Daniel F Pease, Vicki A Morrison
Mantle cell lymphoma (MCL) predominantly affects older adults, with a median age at diagnosis of 70years. A frequently aggressive yet incurable lymphoma, the goal of therapy for MCL is to turn a potentially life-threatening illness into a chronic disease with prolonged periods of remission. Large randomized trial data supports the standard treatment in younger patients of cytarabine-based induction followed by autologous stem cell transplant. Most patients will not be eligible for this intensive approach based on older age, comorbidities, and functional status, making the geriatric assessment an essential step in choosing the appropriate strategy...

Background: Breast cancer oncologists are challenged to personalize care with rapidly changing scientific evidence, drug approvals, and treatment guidelines. Artificial intelligence (AI) clinical decision-support systems (CDSSs) have the potential to help address this challenge. We report here the results of examining the level of agreement (concordance) between treatment recommendations made by the AI CDSS Watson for Oncology (WFO) and a multidisciplinary tumor board for breast cancer...

Birt-Hogg-Dubé syndrome (BHDS) is a rare hereditary autosomal dominant condition characterised by benign cutaneous lesions, lung cysts, increased risk of spontaneous pneumothorax and renal cancer. It shows great heterogenous presentation within and between affected families. We report a case of a Danish female patient with recurrent pneumothoraces as the first symptom of BHDS. Over the years, she developed skin changes, and a family history of skin changes, pneumothoraces and renal cancer was discovered. BHDS was suspected, a genetic analysis was performed and a pathogenic variation c...

INTRODUCTION: Use of chemotherapy for muscle-invasive bladder cancer (MIBC) is known to be low. To understand factors driving practice we use the Theoretical Domains Framework (TDF) to identify barriers and enablers of chemotherapy use. METHODS: A convenience sample of Canadian urologists, medical oncologists (MOs) and radiation oncologists (ROs) participated in individual, semi-structured, one-hour telephone interviews. An interview guide was developed using the TDF to assess potential barriers and enablers of chemotherapy use...

The vast majority of women diagnosed with ovarian cancer present with advanced-stage disease with a five-year survival rate less than 50%. Studies have shown that in the past, gynecologic oncologists were not routinely collaborating with palliative care physicians resulting in goals of care planning often not occurring until the last 30 days before death. In recent years, professional societies have been increasingly more vocal about the importance of incorporating palliative care early in a patient's disease course...

OBJECTIVE: Family members can significantly impact advanced cancer patients' treatment and are important participants in goals of care (GoC) conversations. Yet, research on patient and physician perspectives about family involvement and influence on GoC conversations is limited. Our purpose was to describe patients' and oncologists' perspectives about family involvement and influence on GoC conversations among patients with advanced cancer. METHODS: We conducted semi-structured interviews at academic, community and municipal hospitals (n=4) with patients with advanced cancer (n=39) and their oncologists (n=21)...

BACKGROUND: Li-Fraumeni syndrome (LFS) is a cancer predisposition syndrome caused by mutations in the tumor-suppressor gene TP53. Osteosarcoma is a sentinel cancer in LFS. Prior studies using Sanger sequencing platforms have demonstrated that 3% of individuals with osteosarcoma harbor a mutation in TP53. New data from next-generation sequencing have demonstrated that 3.8% of patients with osteosarcoma have a known pathogenic variant, and an additional 5.7% carry exonic variants of unknown significance in TP53...

Hepatocellular carcinoma (HCC) is the fourth most common and the third most lethal cancer in China. An updated version of consensus-based recommendations on the management of HCC has been recently published by a multidisciplinary group of Chinese experts including liver surgeons, hepatic oncologists, radiologists and pathologists. Major changes have been made to the diagnostic criteria. In addition to dynamic multi-detector computed tomography (CT) and magnetic resonance imaging (MRI), gadoxetic acid-enhanced MRI and contrast-enhanced ultrasound (CEUS) are added to the diagnostic imaging tests...
