Gastrointestinal cancers are a subset of molecularly heterogeneous diseases. In the era of personalised medicine, major efforts are being made towards stratifying patients according to molecular profiling. However, although most treatments are currently based on targeted therapy in relation to specific genomic alterations, acquired resistance emerges during anticancer therapies and subsequently treatment failure occurs. Intratumour heterogeneity plays a significant role in the acquisition of resistance by clonal evolution of tumour cell populations under therapeutic pressure. Despite a single tumour biopsy represents the standard for cancer research and drives our therapeutic decisions, lim…

Glioblastoma (GBM) remains an unmet need in Medical Oncology considering its poor prognosis and the lack of advances in therapeutics in more than one decade.1 Despite the initial enthusiasm, the development of immunotherapy in GBM has proved to be challenging, with a disappointing negative phase III clinical trial.2 Some of the phenotypic hallmarks of GBM make immunotherapy difficult. Its relatively low mutational load, its immunologically ‘cold’ microenvironment with scarce infiltrating immune effector cells, a dominant myeloid compartment composed by microglia and myeloid-derived suppressor cells and a strong immunosuppression, both local, mediated by immunosuppressive regulatory T cells …
Treatment of Lenalidomide Exposed or Refractory Multiple Myeloma: Network Meta-Analysis of Lenalidomide-Sparing Regimens.
2021
Over the past 10 years, the treatment of multiple myeloma (MM) dramatically changed due to the introduction of a number of new agents and combination regimens both in the frontline and in the relapsed/refractory setting. Currently, at least 11 classes of therapeutic agents, including steroids, alkylators (melphalan and cyclophosphamide), proteasome inhibitors (PI: bortezomib, carfilzomib, ixazomib), immunomodulatory agents (thalidomide, lenalidomide, pomalidomide), monoclonal antibodies (mAbs: elotuzumab, daratumumab), HDAC-inhibitors (panobinostat), BCL2 inhibitors (venetoclax), selective inhibitors of nuclear export (selinexor), drug-conjugated mAbs (belantamab mafodotin), bispecific agen…

Immune checkpoint inhibitors are widely used as treatment for an increasing number of solid tumours. Nevertheless, the lack of predictive biomarker represents a limitation across several cancer types. During the last years, the possibility to dynamically study tumour evolution through circulating tumour DNA (ctDNA) in plasma has opened novel possibility in evaluating disease status and therapeutic response, especially in localised disease to predict the possibility of relapse. However, the specific opportunities for application in the context of immunotherapy remain to be clarified.1 In an article recently published in Cancer Discovery by Zhang et al ,2 a comprehensive analysis of ctDNA dat…
Diffusion-weighted imaging in oncology: An update
2020
To date, diffusion weighted imaging (DWI) is included in routine magnetic resonance imaging (MRI) protocols for several cancers. The real additive role of DWI lies in the “functional” information obtained by probing the free diffusivity of water molecules into intra and inter-cellular spaces that in tumors mainly depend on cellularity. Although DWI has not gained much space in some oncologic scenarios, this non-invasive tool is routinely used in clinical practice and still remains a hot research topic: it has been tested in almost all cancers to differentiate malignant from benign lesions, to distinguish different malignant histotypes or tumor grades, to predict and/or assess treatment resp…
Cancer: New Needs, New Models. Is It Time for a Community Oncologist? Another Brick in the Wall
2021
Simple Summary Community care activity in the oncology field does not exist. This unmet need contrasts with the increasing number of patients with a previous diagnosis of cancer. Abstract Over the last few decades, thanks to early detection, effective drugs, and personalized treatments, the natural history of cancer has radically changed. Thanks to these advances, we have observed how survival of cancer patients has increased, becoming an ever more important goal in cancer care. Effective clinical governance of survivorship care is essential to ensure a successful transition between active and post-treatment life, identifying optimization of healthcare outcomes and quality of life for patie…
Do BARD1 Mutations Confer an Elevated Risk of Prostate Cancer?
2021
Simple Summary Current cancer testing gene panels tend to be comprehensive. One of the genes commonly included in the testing panels is BARD1. To establish whether BARD1 mutations predispose to prostate cancer, we sequenced BARD1 in 390 hereditary prostate cancer cases, genotyped 5715 men with unselected prostate cancer and 10,252 controls for three recurrent rare BARD1 variants in Poland. We did not see an elevated prostate risk cancer given p.Q564X truncating mutation, p.R658C missense mutation and p.R659= synonymous variant. Neither variant influenced prostate cancer characteristics or survival. Our study is the first to evaluate the association between BARD1 mutations and prostate cance…
NCOG-03. PERSONALITY TRAITS IN PATIENTS WITH NEUROEPITHELIAL TUMORS – A PROSPECTIVE STUDY
2017
Aim of this study was to analyze personality traits in patients with neuroepithelial brain tumors. Personality alteration is a common feature in brain tumor patients, but not much is known about associations between specific personality changes and brain tumors. We assessed potential factors influencing personality such as tumor location, tumor grade and tumor volume and compared them with neuropsychological tests. 73 patients with intrinsic brain tumors were included in this prospective study. Pre- and postoperatively and 3 and 9 months after surgery, the following data were acquired: mini-mental state examination (MMSE), short form health survey (SF-36), Beck’s Depression Inventory II (BD…

Biliary tract cancer (BTC) includes cholangiocarcinoma and gallbladder cancer. BTCs are known to have a poor prognosis, with a 5-year overall survival below 20%.1 Unfortunately, majority of patients are diagnosed with advanced stage, being palliative chemotherapy with cisplatin and gemcitabine the current standard of care.2 Poor prognosis is due to the fact that only 20% of patients are diagnosed in early stages3 and the high risk of relapse following curative surgery. Unfortunately, the lack of randomised studies has made the role of adjuvant treatment in BTC following surgery an unresolved matter for many years.4 5 Adjuvant therapy (either in the form of chemotherapy or chemoradiotherapy)…
Correction to: Assessment of intratumor immune-microenvironment in colorectal cancers with extranodal extension of nodal metastases
2019
No data is available on the molecular background of the extra-nodal extension (ENE) of lymph node metastasis (LN) in colorectal cancer (CRC).A series of 22 ENE-positive CRCs was considered and three samples per case were selected (the primary CRC, an ENE-negative and an ENE-positive metastatic LN). Samples (n = 66) were analysed by immunohistochemistry for PD-L1, CD4, CD8, CD68 and CD80. Fifteen out of twenty-two cases were further profiled through a hotspot multigene mutational custom panel, including 164 hotspot regions ofA significantly higher percentage of CD4-, CD8- and CD68-positive cells was observed at the invasive front of both CRCs and in ENE in contrast with what observed at the …
