Circulating tumor DNA dynamics and clinical outcome in metastatic colorectal cancer patients undergoing front-line chemotherapy.

Purpose: we tested whether ctDNA changes may be used to assess early response and clinical outcome in metastatic colorectal cancer (mCRC) patients undergoing front-line systemic anti-cancer therapy (SACT).

Experimental Design: 862 plasma samples were collected 4-weekly from baseline (BL) until disease progression in mCRC patients receiving front line SACT. ctDNA normalization was defined as ≥99% clearance after 1 month of therapy (Mo1) in the 3 variants with the highest allele frequency in BL ctDNA.

Pregnancy and Breast Cancer: A Challenge for the Multidisciplinary Team. A Single Center Experience and Narrative Review.

Purpose: The diagnosis of breast cancer during pregnancy is a rare event, but it is more frequent in our daily clinical practice due to the progressing aging of pregnant women. The management of a woman affected by pregnancy-associated breast cancer (PABC) remains a challenge for the clinician as it is related to ethical and psychological decisions.

Patients And Methods: Here, we retrospectively described 10 cases of PABC in women treated at our Institution.

Comparative Efficacy of 21 Treatment Strategies for Resectable Pancreatic Cancer: A Network Meta-Analysis.

The primary treatment for operable pancreatic cancer (PC) involves surgery followed by adjuvant therapy. Nevertheless, perioperative or neoadjuvant chemotherapy (CT) may be used to mitigate the likelihood of recurrence and mortality. This network meta-analysis (NMA) assesses the comparative efficacy of various treatment approaches for resectable PC.

Moderate physical activity during neoadjuvant chemotherapy in breast cancer patients: effect on cancer-related inflammation and pathological complete response-the Neo-Runner study.

Background: Physical activity (PA) reduces the risk of developing breast cancer (BC) and mortality rate in BC patients starting PA after diagnosis. Immunomodulation is considered responsible for these effects. However, limited data exist on the immunomodulation induced by moderate PA (mPA) during neoadjuvant chemotherapy (NACT).

Clinical impact of drug-drug interactions on abemaciclib in the real-world experience of AB-ITALY study.

Abemaciclib demonstrated clinical benefit in women affected by HR+/HER2- advanced breast cancer (aBC). Drug-drug interactions (DDIs) can lead to reduced treatment efficacy or increased toxicity. This retro-prospective study aimed to evaluate outcomes, DDIs' impact, and toxicities of abemaciclib combined with endocrine therapy in a real-world setting.

Different prognosis of left compared to right breast cancer: A systematic review and meta-analysis.

Background: There is an ongoing debate in the medical community about the association between the laterality of breast cancer (BC: whether it arises in the left or right breast) and its outcome. This study aims to assess the disparities in overall survival (OS), cardiac mortality, and cancer-specific survival (CSS) between BC affecting the left side and BC affecting the right side.

Materials And Methods: We conducted a thorough search of databases, such as PubMed, EMBASE, and the Cochrane Library, starting from their inception up until December 1, 2023.

RNA-based next-generation sequencing (NGS) is being used with increasing frequency for solid tumors. The purpose of our study is to investigate the feasibility and utility of an RNA-based NGS fusion panel for solid tumors.

Chromobacterium violaceum in a U.S. Marine: A Case Report.

Chromobacterium violaceum is associated with severe sepsis leading to cutaneous and visceral organ abscesses, with mortality rates up to 73%. Around 200 cases of C. violaceum infection have been reported globally.

Prognostic Value of HER2-low Status in ER+ Early Breast Cancer: A Systematic Review and Meta-Analysis.

Background/aim: Low human epidermal growth factor receptor 2 expression (HER2-low: 1+/2+ by immunohistochemistry without HER2 amplification) is emerging as defining a specific breast cancer (BC) subgroup owing to its distinct biological features. However, its prognostic role has not been confirmed in clinical practice. We conducted a systematic review and meta-analysis to determine the prognostic role of HER2-low status in patients with estrogen receptor-positive (ER+) early BC.

Inflammatory Bowel Diseases: An Updated Overview on the Heat Shock Protein Involvement.

Inflammatory bowel diseases (IBDs) represent chronic idiopathic disorders, including Crohn's disease (CD) and ulcerative colitis (UC), in which one of the trigger factors is represented by aberrant immune interactions between the intestinal epithelium and the intestinal microbiota. The involvement of heat shock proteins (HSPs) as etiological and pathogenetic factors is becoming of increasing interest. HSPs were found to be differentially expressed in the intestinal tissues and sera of patients with CD and UC.

A new method for oral cancer biomarkers detection with a non-invasive cyto-salivary sampling and rapid-highly sensitive ELISA immunoassay: a pilot study in humans.

Introduction: Oral squamous cell carcinoma (OSCC) accounts for approximately 90% of oral malignancies and has a 5-year mortality rate close to 50%. A consistent part (70%) of all oral cancers is diagnosed at an advanced stage since available screening techniques are ineffective. Therefore, it would be urgent to improve them.

Efficacy of different maintenance strategies for RAS wild-type colorectal cancer: A network meta-analysis.

Introduction: In metastatic RAS wild-type colorectal cancer (CRC), induction combination chemotherapy doublets (CT) with an anti-EGFR agent are considered the primary treatment. We performed a network meta-analysis (NMA) to compare the relative efficacy of different maintenance treatments for advanced RAS wild-type CRC.

Materials And Methods: PubMed, EMBASE and Cochrane, from database inception until December 2021 were used.

Comparison of different second line treatments for metastatic pancreatic cancer: a systematic review and network meta-analysis.

Background: In metastatic pancreatic ductal adenocarcinoma (mPDAC), first line treatment options usually include combination regimens of folinic acid, 5-fluorouracil (5-FU), irinotecan, and oxaliplatin (FOLFIRINOX or mFOLFIRINOX) or gemcitabine based regimens such as in combination with albumin-bound paclitaxel (GEM + nab-PTX). After progression, multiple regimens including NALIRI + 5-FU and folinic acid, FOLFIRINOX, 5-FU-based oxaliplatin doublets (OFF, FOLFOX, or XELOX), or 5-FU-based monotherapy (FL, capecitabine, or S-1) are considered appropriate by major guidelines. This network meta-analysis (NMA) aimed to compare the efficacy of different treatment strategies tested as second-line regimens for patients with mPDAC after first-line gemcitabine-based systemic treatment.

Adverse events during first-line treatments for mCRC: The Toxicity over Time (ToxT) analysis of three randomised trials.

Background: In clinical trials, the assessment of safety is traditionally focused on the overall rate of high-grade and serious adverse events (AEs). A new approach to AEs evaluation, taking into account chronic low-grade AEs, single patient's perspective, and time-related information, such as ToxT analysis, should be considered especially for less intense but potentially long-lasting treatments, such as maintenance strategies in metastatic colorectal cancer (mCRC).

Patients And Methods: We applied ToxT (Toxicity over Time) evaluation to a large cohort of mCRC patients enroled in randomised TRIBE, TRIBE2, and VALENTINO studies, in order to longitudinally describe AEs throughout the whole treatment duration and to compare AEs evolution over cycles between induction and maintenance strategies, providing numerical and graphical results overall and per single patient.

Dissecting the genetic heterogeneity of gastric cancer.

Background: Gastric cancer (GC) is clinically heterogenous according to location (cardia/non-cardia) and histopathology (diffuse/intestinal). We aimed to characterize the genetic risk architecture of GC according to its subtypes. Another aim was to examine whether cardia GC and oesophageal adenocarcinoma (OAC) and its precursor lesion Barrett's oesophagus (BO), which are all located at the gastro-oesophageal junction (GOJ), share polygenic risk architecture.

Anti-Claudin Treatments in Gastroesophageal Adenocarcinoma: Mainstream and Upcoming Strategies.

Claudins (CLDNs) are a multigene family of proteins and the principal components of tight junctions (TJs), which normally mediate cell-cell adhesion and selectively allow the paracellular flux of ions and small molecules between cells. Downregulation of claudin proteins increases the paracellular permeability of nutrients and growth stimuli to malignant cells, which aids the epithelial transition. Claudin 18.
