How to deal with second line dilemma in metastatic colorectal cancer? A systematic review and meta-analysis.

2019

e15006 Background: Monoclonal antibodies targeting epidermal growth factor receptor (EGFR) or vascular endothelial growth factor (VEGF) have demonstrated efficacy in combination with chemotherapy as second line for metastatic colorectal cancer (mCRC). However, there is still a paucity of evidence or guidelines suggesting the right sequential treatment in all RAS (KRAS/NRAS) wild type(wt)mCRC. Therefore, we aimed to evaluate the impact of these targeted therapies by reviewing literature data. Methods: We used Cochrane, EMBASE and Medline databases to select phase III clinical trials containing efficacy and safety data about chemotherapy (CT) or CT + targeted agents combination (Anti-VEGF an…

Colorectal Cancer: Metastatic Disease

2021

Most patients diagnosed with metastatic colorectal cancer (mCRC) develop metastases during the disease course after resection of the primary locoregional cancer. To date, the liver represents the most common site of metastatic involvement. Although several different biological and clinical hallmarks exist between the colon and rectum (different embryological origin, anatomy, and molecular biology), mCRC requires similar staging procedures and systemic treatment strategies (first and subsequent lines) in terms of a multimodal approach treatment as a part of a “continuum of care.” Patients affected by oligometastatic disease should undergo an upfront evaluation by a multidisciplinary team for…

Cell-free DNA and exoDNA analysis in metastatic colorectal cancer patients (mCRC).

2020

e16093 Background: Liquid biopsy is a growing field in translational cancer research. Two of the most studied liquid biopsy biomarkers are cell-free DNA (cfDNA) and exosomes, nano-sized vesicles that transport protein and nucleic acids including DNA (exoDNA). Therefore, both cfDNA and exoDNA are potentially useful to investigate the molecular landscape of tumor with a minimally invasive approach. Here we investigate the prognostic and predictive role of both cfDNA and exoDNA in mCRC using Next Generation Sequencing (NGS) analysis. Methods: From July 2017 to September 2018, samples of 40 mCRC patients were collected at the Medical Oncology of the AOUP Paolo Giaccone of Palermo. Blood sample…

Analysis of systemic inflammatory biomarkers in neuroendocrine carcinomas of the lung: prognostic and predictive significance of NLR, LDH, ALI, and L…

2020

Background: Lung neuroendocrine carcinoma (NEC) is characterized by aggressive clinical behavior and lack of treatment advances. We evaluate the prognostic and the predictive roles of systemic inflammatory biomarkers in patient circulating blood: neutrophil–lymphocyte ratio (NLR), lactate dehydrogenase (LDH), advanced lung cancer inflammation index (ALI), and the Lung Immune Prognostic Index (LIPI) score. Methods: A total of 120 patients with small-cell lung cancer (SCLC) ( n = 110) and large cell neuroendocrine carcinoma (LCNEC) ( n = 10) were enrolled. Overall survival (OS) was evaluated by Kaplan–Meier estimator and univariate and multivariate Cox proportional hazard analyses were perfor…

Virtual Multidisciplinary Tumor Boards: A Narrative Review Focused on Lung Cancer

2021

To date, the virtual multidisciplinary tumor boards (vMTBs) are increasingly used to achieve high-quality treatment recommendations across health-care regions, which expands and develops the local MTB team to a regional or national expert network. This review describes the process of lung cancer-specific MTBs and the transition process from face-to-face tumor boards to virtual ones. The review also focuses on the project organization's description, advantages, and disadvantages. Semi-structured interviews identified five major themes for MTBs: current practice, attitudes, enablers, barriers, and benefits for the MTB. MTB teams exhibited positive responses to modeled data feedback. Virtualiz…

An update on the conquests and perspectives of cardio-oncology in the field of tumor angiogenesis-targeting TKI-based therapy.

2019

Introduction: The angiogenesis mechanism is considered a crucial point in neoplastic development. A growing number of multi-targeted tyrosine kinase inhibitors (TKI) has been developed and approved for cancer treatment during the last few years. Cardiac side effects still remain an issue to manage nowadays. These drugs mechanisms and toxicities have already been discussed, hence the authors will report updates on these already available drugs. Area covered: This manuscript provides an updated review on the new mechanisms involved in angiogenesis and cardiotoxicity that are TKI-related. Here is reported an overview of the already available and the most recent TKIs under investigation in the …

Vulvar and Vaginal Cancers

2021

Vulvar cancer and vaginal cancer are relatively rare tumors, typically affecting elder women, although they still represent the fourth and fifth, respectively, most common cancers in the gynecologic oncology field. Treatment of the early stages includes surgery and radiotherapy (external beam radiotherapy and brachytherapy). The sentinel lymph node sampling procedure is becoming the new standard of care in vulvar cancer. Chemotherapy has a role in combination with radiotherapy for the locoregional management or as palliative therapy for stage IV patients.

A novel predictive biomarker of immunotherapy response in metastatic renal cell carcinoma (mRCC): The lymphocyte microRNA expression profile.

2019

e16109 Background: Predicting which patient with metastatic renal cell carcinoma (mRCC) will benefit from immune checkpoints inhibitors (ICPIs) still remain an issue. Biological factors particular to certain individuals have a clear effect on variation in response. Emerging evidence suggests that small non-coding RNA, such as microRNAs (miRNAs), are critical modulators of numerous cellular processes, including immune surveillance. The main aim of this study was to analyze the lymphocyte miRNA expression profile in mRCC patients and dynamic changes after the treatment with ICPI, in order to investigate the molecular mechanisms and signaling pathways involved in ICPI response and their poten…

How to Deal with Second Line Dilemma in Metastatic Colorectal Cancer? A Systematic Review and Meta-Analysis

2019

Monoclonal antibodies targeting epidermal growth factor receptor (EGFR) or vascular endothelial growth factor (VEGF) have demonstrated efficacy with chemotherapy (CT) as second line treatment for metastatic colorectal cancer (mCRC). The right sequence of the treatments in all RAS (KRAS/NRAS) wild type (wt) patients has not precisely defined. We evaluated the impact of aforementioned targeted therapies in second line setting, analyzing efficacy and safety data from phase III clinical trials. We performed both direct and indirect comparisons between anti-EGFR and anti-VEGF. Outcomes included disease control rate (DCR), objective response rate (ORR), progression-free survival (PFS), overall su…

Impact of phospho-Akt expression on the clinical outcome and activity of gemcitabine and Akt inhibitors in pancreatic ductal adenocarcinoma

2017

Background: Pancreatic ductal adenocarcinoma (PDAC) is among the most lethal solid tumors. Despite extensive preclinical and clinical research, the prognosis of this disease has not significantly improved, with a 5-year survival rate around 7%. There is an urgent need to better understand the molecular pathology of PDAC in order to improve patient selection for current treatment options and to develop novel therapeutic strategies. The PI3K/AKT/mTOR pathway plays a crucial role in PDAC: activation of Akt is a frequent event and has been correlated to poor prognosis and resistance to chemotherapy. Against this background, effective blockage of Akt signaling can lead to programmed cell death a…

Can the plasma PD-1 levels predict the presence and efficiency of tumor-infiltrating lymphocytes in metastatic melanoma patients?

2019

e14035 Background: The immune response to melanoma has been shown to be locally affected by presence of tumor-infiltrating lymphocytes (TILs), generally divided into brisk (infiltrating the entire base of the invasive tumor), non-brisk (infiltrating only focally) and absent. Several studies showed that greater presence of TILs, especially brisk, in primary melanoma is associated with a better prognosis and a higher survival rate. Since recent studies revealed an association between PD-1/PD-L1 expression levels and tumor response, the aim of our study was to investigate the correlation between plasma PD-1 and presence/absence/class of TILs in metastatic melanoma patients. Methods: The plasm…

Mini-Invasive Approach Contributes to Expand the Indication for Liver Resection for Hepatocellular Carcinoma Without Increasing the Incidence of Post…

2016

Liver resection (LR) for hepatocellular carcinoma (HCC) is the best alternative option for increasing the survival of many patients with intermediate or advanced stages of the Barcelona Clinic Liver Cancer staging classification. Mini-invasive approach may play a positive role in treating a tumor rising almost exclusively in a diseased liver.A prospectively collected database was retrospectively reviewed for 167 consecutive patients who underwent LR between 1999 and 2015.A total of 38 LRs were performed from 1999 to 2009 (Period I), and 129 between 2010 and 2015 (Period II). Laparoscopic procedures increased from 5.3% to 38.1%. Not undergoing laparoscopic LR increased length of stay, and Cl…

E26The effects of LIPUS on ctDNA release in the medium of NSCLC cell lines

2017

Low Intensity Pulsed Ultrasound (LIPUS) application has been shown to have an encouraging effect in inducing a transient pore formation through cellular membranes. This permeability condition has been demonstrated to be useful in enhancing gene and drug delivery. Nowadays, in the management of NSCLC patients, the use of liquid biopsy has entered the clinical practice. One of the main limits in the analysis of circulating tumor DNA is the low concentration rate of nucleic acids in body fluids. Ultrasound stimulation (US) has been recently demonstrated to be effective for the release of specific circulating tumor biomarkers in many mouse models. We demonstrated the role of US in inducing the …
