Interleukin-30 feeds breast cancer stem cells via CXCL10 and IL23 autocrine loops and shapes immune contexture and host outcome
2021
BackgroundBreast cancer (BC) progression to metastatic disease is the leading cause of death in women worldwide. Metastasis is driven by cancer stem cells (CSCs) and signals from their microenvironment. Interleukin (IL) 30 promotes BC progression, and its expression correlates with disease recurrence and mortality. Whether it acts by regulating BCSCs is unknown and could have significant therapeutic implications.MethodsHuman (h) and murine (m) BCSCs were tested for their production of and response to IL30 by using flow cytometry, confocal microscopy, proliferation and sphere-formation assays, and PCR array. Immunocompetent mice were used to investigate the role of BCSC-derived IL30 on tumor…

Malignant pleural mesothelioma (MPM) is a rare and lethal cancer associated to asbestos exposure. Currently, the pemetrexed and cisplatin combination chemotherapy remains the only approved treatment. In the last 5 years, a growing knowledge on mesothelioma pathobiology has translated into the development of multiple novel therapeutic strategies.1 One of the largest reports of comprehensive genomic profiling of MPM was conducted by Bueno and colleagues. Using RNA-seq data, they identified four distinct molecular subtypes, and through exome analysis, they found that BAP1 , NF2 , TP53 , SETD2 , DDX3X , ULK2 , RYR2 , CFAP45 , SETDB1 and DDX51 were significantly mutated.2 In an article recently …

Poly (ADP-ribose) polymerase (PARP) inhibitors (PARPi) are a highly active family of compounds that have changed the scenario in ovarian and human epidermal growth factor receptor 2 (HER2) non-amplified breast cancer management in the recent years. Despite impressive clinical activity, a prolonged treatment with PARPi is frequently associated with acquired resistance to this therapy. The identification of mechanisms and strategies to overcome resistance are crucial. Bromodomain containing 4 (BRD4) is a member of the bromodomain and extraterminal (BET) protein family that facilitates oncogenic transcription. BRD4 is frequently amplified in high-grade serous ovarian cancer (HGSOC) and can be …

Immunotherapy based on checkpoint blockade has revolutionised cancer treatment during last years. Whereas this approach fails in a relevant group of patients, the knowledge on tumour microenvironment (TME) opened the possibility to the use of additional therapeutic strategies to potentiate antitumour immunity, including depletion of protumourigenic or immune suppressive and activation of specific immune populations using agonistic antibodies. Nevertheless, due to the complexity of the TME, many of these strategies have been indiscriminately advanced to the clinic without clear mechanistic hypotheses. Nowadays, single-cell RNA sequencing (scRNA-seq)-based transcriptome analyses identify T ce…
Aurora kinases in ovarian cancer
2020
Aurora kinases (AURK) are key regulators of the mitotic spindle formation. AURK is frequently overexpressed in ovarian cancer and this overexpression has been frequently associated with prognosis in these tumours. Interestingly, AURK have been shown to interact with DNA repair mechanisms and other cell cycle regulators. These functions have brought light to Aurora family as a potential target for anticancer therapy. In the last years, two clinical trials with different AURK inhibitors have shown activity in epithelial and clear-cell ovarian cancer. Although there is a lack of predictive factors of AURK inhibition activity, recent trials have identified some candidates. This review will focu…

The introduction of new high-throughput technologies in oncology and the need to apply precision medicine for cancer patients has led to the detection of several molecular alterations. Among them, activating mutations of ERBB2 have been reported in many solid tumours. In the last years, several clinical trials with covalent tyrosine kinase inhibitors (TKIs) for ERBB2 mutant cancers have been conducted, with different results among several cancer types. In the SUMMIT trial, neratinib was most effective in breast cancer patients, with the majority of responders having tumours with L755S, V777L, or L869R ERBB2 mutations.1 In an elegant article published in C ancer C ell by Robichaux et al ,2 d…

The phosphatidylinositol-3-kinase (PI3K)/Akt and the mammalian target of rapamycin (mTOR) signaling pathways is one of the most frequently deregulated pathways in human cancers. This pathway controls multiple cellular processes, including metabolism, motility, proliferation, growth and survival. It can be aberrantly activated through multiple mechanisms, including diverse genomic alterations involving oncogenes and tumour suppressor genes.1 These alterations offer opportunities for therapeutic targeting of the pathway. PI3Kα protein complex is composed of regulatory (p85α) and catalytic (p110α) subunits. Pik3ca codes for p110α, which is the most frequently mutated oncogene across different …
Management of orphan symptoms: ESMO Clinical Practice Guidelines for diagnosis and treatment†
2020
### Highlights There is no clear definition of orphan symptoms. There is a group of symptoms that are seldom evaluated in most symptom assessment tools which can be considered as orphan symptoms.1 These are generally prevalent symptoms that are unaddressed in clinical practice, yet often not reported by the patients or by healthcare professionals.2 Orphan symptoms may be defined as symptoms not regularly assessed in clinical practice, and consequently little studied and not properly treated. No epidemiological or clinical studies generally exist to gauge the prevalence of the symptoms chosen; nevertheless, these symptoms are distressing for patients and their families. Orphan symptoms remai…

Immune checkpoint inhibitors (ICI) have become a key component of therapy for several solid tumours. In patients diagnosed with advanced clear cell renal cell carcinoma (ccRCC), immunotherapy has always been considered as a treatment option, and anti-PD-1-based therapies are approved in both the frontline and refractory settings. Response to PD-1 blockade has been associated with numerous tumour-intrinsic and microenvironment features. Genetic characterisation of ccRCC has significantly contributed to the knowledge of tumour biology and the mechanisms of disease progression, but the interplay of genomic alterations with patterns of immune infiltration in response to PD-1 blockade remains un…
Overall survival at 5 years of follow-up in a phase III trial comparing ipilimumab 10 mg/kg with 3 mg/kg in patients with advanced melanoma
2020
BackgroundWe have previously reported significantly longer overall survival (OS) with ipilimumab 10 mg/kg versus ipilimumab 3 mg/kg in patients with advanced melanoma, with higher incidences of adverse events (AEs) at 10 mg/kg. This follow-up analysis reports a 5-year update of OS and safety.MethodsThis randomized, multicenter, double-blind, phase III trial included patients with untreated or previously treated unresectable stage III or IV melanoma. Patients were randomly assigned (1:1) to ipilimumab 10 mg/kg or 3 mg/kg every 3 weeks for 4 doses. The primary end point was OS.ResultsAt a minimum follow-up of 61 months, median OS was 15.7 months (95% CI 11.6 to 17.8) at 10 mg/kg and 11.5 mont…
