Global and sex-specific epigenome-wide association studies for the identification of the main methylated loci related to smoking in a mediterranean p…
2019
Abstract Background Tobacco use has been reported to be the main cause of 90% of male and 80% of female lung cancers, as well as a relevant risk factor for other cancers such as oropharynx, larynx, esophagus, stomach, liver, pancreas, kidney, bladder, and colorectum. Smoking directly affects DNA methylation and although several genes have been reported to be differentially methylated in smokers, gender differences and population-specific differences remain to be further investigated. Our aim was to undertake global and sex-specific genome-wide epigenomic studies (EWAS) in a Mediterranean population to identify the main smoking DNA-methylated genes. Methods We analyzed 88 participants in the…
Central Nervous System Malignancies
2021
The primitive neoplasms of the central nervous system (CNS) are a rare and heterogeneous group of malignancies. Brain metastases (BMs) are the most frequent intracranial tumor, and their incidence is rising in the last few decades. Primary tumors more often complicated by BMs are lung cancer, breast cancer, and melanoma. Neuroimaging techniques, mainly magnetic resonance imaging (MRI), play a key role for the diagnosis of BMs. The management of BMs is based on a multimodal approach, including symptomatic treatment, local treatment, such as surgery, stereotactic radiosurgery (SRS), and whole brain radiotherapy (WBRT), and systemic therapy, such as chemotherapy, target therapy, or immunothera…
Is there any place for PD-1/CTLA-4 inhibitors combination in the first-line treatment of advanced NSCLC?—A trial-level meta-analysis in PD-L1 selecte…
2021
BACKGROUND: The advent of immuno-oncology (IO) represented a breakthrough in non-small cell lung cancer (NSCLC) therapy over the last few years. However, establishing the optimal therapeutic options among programmed death-ligand 1 (PD-L1) selected subgroups still addresses an unmet need in the clinical setting. METHODS: We performed a systematic review and finally included eleven first-line randomized controlled trials to compare efficacy and safety outcomes among first-line IO treatment strategies versus standard platinum-based chemotherapy (CT) according to PD-L1 expression level (<1%, 1–49%, ≥50%). Pooled hazard ratios (HRs) and risk ratios (RRs) for progression-free survival (PFS), over…
Tea Consumption and Risk of Cancer
2020
Tea is one of the most widely consumed beverages, but its association with cancer risk remains controversial and unclear. We performed an umbrella review to clarify and determine the associations between tea consumption and various types of cancer by summarizing and recalculating the existing meta-analyses. Meta-analyses of observational studies reporting associations between tea consumption and cancer risk were searched on PubMed and Embase. Associations found to be statistically significant were further classified into levels of evidence (convincing, suggestive, or weak), based on P value, between-study heterogeneity, prediction intervals, and small study effects. Sixty-four observational…
Neoadjuvant chemotherapy for stage IIIA-N2 non-small cell lung cancer
2005
Neoadjuvant chemotherapy in potentially resectable stage IIIA-N2 non-small cell lung cancer (NSCLC) has become standard of treatment in the last years. Two randomised pioneer phase III trials conducted with second generation platinum combinations had demonstrated an advantage in survival of induction chemotherapy followed by surgery versus surgery alone. Subsequently, a wide number of phase II studies with third generation platinum-based doublets or triplets have increased the evidence of the activity as well as the good tolerability of this approach. Nowadays, the main topics of ongoing clinical research are to assess the role of induction chemotherapy in early stage disease, and the role …
“Comparison of the safety and efficacy of paclitaxel plus gemcitabine combination in young and elderly patients with locally advanced or metastatic n…
2008
We retrospectively assessed tolerability and efficacy of paclitaxel plus gemcitabine combination in 259 patients with locally advanced or metastatic non-small cell lung cancer (NSCLC) enrolled in three randomized SICOG trials according to their age (70 years) at study entry. Apart from age, demographic and clinical characteristics were similar in the two groups. Response rate of paclitaxel plus gemcitabine was similar in younger and in elderly (36% versus 30%). Chemotherapy was well tolerated, but severe neutropenia (12% versus 7%), anaemia (6.6% versus 1.8%), and vomiting (5% versus 0) were more frequent in elderly patients. Both median progression-free survival (PFS, 5.5 months versus 4.2…
Interstitial lung disease associated with drug therapy
2004
Drug-associated interstitial lung disease (ILD) is not uncommon, with diverse patterns ranging from benign infiltrates to the potentially fatal acute respiratory distress syndrome. As acute respiratory failure due to drug-associated ILD has an unpredictable onset and rapid time course, establishing a diagnosis is often difficult. An accurate diagnosis is based on clinical, radiological (including high-resolution computed tomography) and histological manifestations, although is often only possible by exclusion. Cancer chemotherapy is commonly associated with acute disease that, on pathology, is often diffuse alveolar damage. Furthermore, a combination of drugs with or without radiotherapy ca…
Parathyroid hormone-related protein (PTHrP)-dependent modulation of gene expression signatures in cancer cells
2022
PTHrP is encoded by PTHLH gene which can generate by alternative promoter usage and splicing mechanisms at least three mature peptides of 139, 141 and 173 amino acids with distinct carboxy terminus. PTHrP may undergo proteolytic processing into smaller bioactive forms, comprising an amino terminus peptide, which is the mediator of the "classical" PTH-like effect, as well as midregion and carboxy terminus peptides that act as multifaceted critical regulator of proliferation, differentiation and apoptosis via the reprogramming of gene expression in normal and neoplastic cells. Moreover, a nuclear/nucleolar localization signal sequence is present in the [87-107] domain allowing PTHrP nuclear i…
Antiamphiphysin-positive stiff-person syndrome associated with small cell lung cancer
2006
The paraneoplastic amphiphysin(+) stiff-person syndrome (SPS) has so far only been described in women with breast adenocarcinoma. Here, we describe the rare case of a female patient with antiamphiphysin(+) SPS due to small cell cancer of the lung.
