Changes in clinical presentation, management, and survival outcomes in patients affected by colorectal cancer following COVID-19 pandemic.

Background: As an extended analysis of the COVID-DELAY study, we aimed to assess the impact of the COVID-19 pandemic on diagnosis, staging, and survival outcomes among patients with colorectal cancer (CRC) diagnosis performed from 2019 to 2022.

Methods: All consecutive newly diagnosed CRC patients referred to 11 Italian Oncology Departments between March and December 2019, 2020, 2021, and 2022 were enrolled. Access rate, demographics, diagnostic-therapeutic temporal intervals, and first-line progression-free survival (PFS) and OS among metastatic patients were assessed.

Modulation of pancreatic cancer cell sensitivity to FOLFIRINOX through microRNA-mediated regulation of DNA damage.

FOLFIRINOX, a combination of chemotherapy drugs (Fluorouracil, Oxaliplatin, Irinotecan -FOI), provides the best clinical benefit in pancreatic ductal adenocarcinoma (PDAC) patients. In this study we explore the role of miRNAs (MIR) as modulators of chemosensitivity to identify potential biomarkers of response. We find that 41 and 84 microRNA inhibitors enhance the sensitivity of Capan1 and MiaPaCa2 PDAC cells respectively.

An observational retrospective analysis of the main metastatic site and corresponding locoregional treatment as a prognostic factor in metastatic gastric cancer.

Despite novel drugs, the prognosis for patients with metastatic gastric cancer remains poor. In rare instances, locoregional therapies are used in addition to standard chemotherapy in patients with oligometastatic involvement. This type of approach has not been supported by solid published evidence.

Systemic immune-inflammation index: a prognostic tiebreaker among all in advanced pancreatic cancer.

Background: Pancreatic ductal adenocarcinoma (PDAC) detains a dismal prognosis and has a limited number of prognostic factors. Inflammation has been demonstrated to play a key role both in PDAC initiation and progression and several inflammation-based prognostic scores have been investigated in a wide range of malignancies. We compared the most analyzed inflammation-based prognostic scores in order to establish their potential impact on prediction of the outcome in advanced PDAC patients.

Old but gold: the role of drug combinations in improving response to immune check-point inhibitors in thoracic malignancies beyond NSCLC.

The introduction of immune checkpoint inhibitors (ICIs) in non-oncogene addicted non-small cell lung cancer (NSCLC) has revolutionized the treatment scenario and led to a meaningful improvement in patient prognosis. Disappointingly, the success of ICI therapy in NSCLC has not been fully replicated in other thoracic malignancies as small cell lung cancer (SCLC), malignant pleural mesothelioma (MPM), and thymic epithelial tumors (TETs), due to the peculiar biological features of these disease and to the difficulties in the conduction of well-designed, biomarker-driven clinical trials. Therefore, combination strategies of ICIs plus conventional therapies (either chemotherapy, alternative ICIs or targeted agents) have been implemented.

High-intensity statins are associated with improved clinical activity of PD-1 inhibitors in malignant pleural mesothelioma and advanced non-small cell lung cancer patients.

Background: In preclinical models, statins showed vaccine adjuvant activities and synergized with PD-1 inhibitors. We analyzed the impact of statin treatment on clinical outcome in thoracic cancer patients treated with PD-1 inhibitors.

Methods: A total of 82 malignant pleural mesothelioma (MPM) and 179 advanced non-small cell lung cancer (aNSCLC) patients treated with PD-1 inhibitors as second or further line treatment were examined.

Impact of Polypharmacy for Chronic Ailments in Colon Cancer Patients: A Review Focused on Drug Repurposing.

Colorectal cancer is characterized by high incidence worldwide. Despite increased awareness and early diagnosis thanks to screening programmes, mortality remains high, particularly for patients with metastatic involvement. Immune checkpoint inhibitors or poly (ADP-ribose) polymerase (PARP)-inhibitors have met with disappointing results when used in this setting, opposed to other malignancies.

Acute Peripheral Motor Neuropathy Induced by Oxaliplatin-Correlated Hypokalaemia.

Neurotoxicity is one of the most common side effects of oxaliplatin-based therapy. Most patients who receive at least 3-4 months of treatment suffer from peripheral sensory neurotoxicity (PSN), characterised by the loss or impairment of tactile and proprioceptive sensory function. Motor impairment, such as muscle weakness or palsy, has been rarely described, and the physiopathology of PSN, as well as the motor symptoms due to oxaliplatin-based treatment, are not adequately understood.

The Risk Assessment in Low-Grade Gliomas: An Analysis of the European Organization for Research and Treatment of Cancer (EORTC) and the Radiation Therapy Oncology Group (RTOG) criteria.

Diffuse low-grade gliomas (LGG) are rare tumors that affect young adult patients. The European Organization for Research and Treatment of Cancer (EORTC) and the Radiation Therapy Oncology Group (RTOG) have both developed their own clinical prognostic scores to assist clinicians in treatment decision-making. These criteria have been used to include patients in phase III studies.

The role of clinical and molecular factors in low-grade gliomas: what is their impact on survival?

Aim: To evaluate relevance of clinical and molecular factors in adult low-grade gliomas (LGG) and to correlate with survival.

Methods: We reviewed records from adult LGG patients from 1991 to 2015 who received surgery and had sufficient tissue to molecular biomarkers characterization.

Results: 213 consecutive LGG patients were included: 17.

Are liver nested stromal epithelial tumors always low aggressive?

Nested stromal-epithelial tumor (NSET) is a non-hepatocytic and non-biliary tumor of the liver consisting of nests of epithelial and spindled cells with associated myofibroblastic stroma and variable intra-lesional calcification and ossification, which represents a very rare and challenging disease. Most of the reported cases have been treated with surgery, obtaining a long survival outcome. Here, we report the case of a 31-year-old Caucasian man who underwent surgery at our institution for a large, lobulated, multinodular mass of the right hemi-liver.

Immunotherapy in head and neck cancer: evidence and perspectives.

Head and neck squamous cell carcinomas evade immune response through multiple immunologic resistance mechanisms. Two of the most commonly involved checkpoint inhibitory mechanisms are CTLA-4 and PD-1/PD-L1, which act at earlier and later stages of immune response to tumors. Pembrolizumab and nivolumab are PD-1 antibodies that interrupt the immunosuppressive pathway of inhibitory checkpoints, which are used by tumor cells to prevent immune reaction.

KRAS mutation status is associated with specific pattern of genes expression in pancreatic adenocarcinoma.

Aims: To evaluate potential differences at a molecular level between KRAS mutant tumors (MT) and KRAS wild-type (WT) pancreatic tumors and the biological and prognostic significance of different KRAS mutations.

Materials & Methods: Expression of a panel of 29 genes was analyzed in KRAS WT and MT tumors. Effects of KRAS mutation and gene expression levels were assessed on patients' survival.

HER family receptor expression and prognosis in pancreatic cancer.

Background: HER family receptors play a key role in tumor progression in several malignancies, such as colorectal, lung or breast cancer. The aims of this study were to investigate expression of HER-1, HER-2 and HER-3 in pancreatic cancer (PC) samples and evaluate the association between HER-family receptor expression and patients' clinical outcomes.

Methods: Tissue samples from 91 PC patients were subjected to immunohistochemical staining to assess the expression of HER-1, HER-2 and HER-3.

Risk of pruritus in cancer patients treated with biological therapies: A systematic review and meta-analysis of clinical trials.

Background: Pruritus has been described with targeted therapies in cancer patients. We performed an up-to-date meta-analysis to determine the incidence and RR in patients with cancer treated with these agents.

Methods: PubMed databases were searched for articles published till October 2014.

Toll like receptors and pancreatic diseases: From a pathogenetic mechanism to a therapeutic target.

Toll-like receptors (TLRs) mediate interactions between environmental stimuli and innate immunity. TLRs play a major role in the development of numerous pancreatic diseases, making these molecules attractive as potential therapeutic targets. TLR2, TLR7 and TLR9 are involved in the initiation of type 1 diabetes mellitus (T1DM), whereas TLR2 and TLR4 play a major role in the onset of type 2 diabetes mellitus (T2DM).

[Treatment of pancreatic cancer. Actuality and perspective].

Pancreatic ductal adenocarcinoma (PDAC) is still one of the deadliest solid malignancies, with an extremely poor prognosis, with a 1-year survival rate of approximately 20%. Low survival rates of PDAC mainly derive from late diagnosis, with only a minority of patients amenable to surgery, as well as high rates of relapse and lack of effective treatments for advanced disease stages. As a result, there is an urgent need for the development of new effective therapies.

Lgr5 expression, cancer stem cells and pancreatic cancer: results from biological and computational analyses.

Aims: To determine the relationship between Lgr5 and other stemness markers and pathologic features in pancreatic ductal adenocarcinoma (PDAC) samples.

Materials & Methods: In 69 samples, Lgr5 was analyzed by qRT-PCR together with a panel of 29 genes. Bioinformatic analysis was carried out to identify a possible pathway regulating Lgr5 expression in PDAC.

Neoadjuvant therapy in pancreatic cancer: an emerging strategy.

Pancreatic adenocarcinoma (PDAC) is the fourth leading cause of cancer deaths among men and women, being responsible for 6% of all cancer-related deaths. Surgical resection offers the only chance of cure, but only 15 to 20 percent of cases are potentially resectable at presentation. In recent years, increasing evidences support the use of neoadjuvant strategies in pancreatic cancer in patients with resectable pancreatic cancer as well as in patients with borderline resectable or locally advanced PDAC in order to allow early treatment of micrometastatic disease, tumour regression, and reduced risk of peritoneal tumour implantation during surgery.
