Background: Cervical cancer is primarily caused by persistent human papilloma virus (HPV) infections, with significant disparities observed in its burden, especially affecting immigrant populations from high HPV prevalence regions. This study evaluates the incidence and severity of cervical cancer in immigrant women in the Marche region, Italy, from 2010 to 2019.

Methods: We employed a detailed analysis of population-based data from the Marche Cancer Registry using the age-standardised incidence rates (IRs) and Poisson regression models for in situ cervical cancer (ISCC) and infiltrating cervical cancer (ICC).

Background: The MILES and ELVIS studies showed that vinorelbine is one of the best options for elderly patients with advanced non-small-cell-lung cancer (NSCLC). Oral vinorelbine at standard schedule (60-80 mg/m/weekly) has good activity in terms of response rates and progression-free survival. In recent years, a metronomic schedule of oral vinorelbine (40-50 mg/m three times a week, continuously) has been studied in phase II trials, especially in unfit and elderly patients.

Background: Regorafenib (REG) has now been approved as the standard third-line therapy in metastatic gastrointestinal stromal tumour (GIST) patients at the recommended dose and schedule of 160 mg once daily for the first 3 weeks of each 4-week cycle. However, it has a relevant toxicity profile that mainly occurs within the first cycles of therapy, and dose and schedule adjustments are often required to reduce the frequency or severity of adverse events and to avoid early treatment discontinuation. To date, large amounts of data on the use of REG in metastatic GIST patients in daily clinical practice are not available, and we lack information about how this treatment personalization really affects the quality of life (QoL) of patients.

Lynch syndrome is caused by germline mutations in any of the MisMatch Repair (MMR) genes. About 37% of MSH2 variants are missense variants causing single amino-acid substitutions. Whether missense variants affect the normal function of MMR proteins is crucial both to provide affected families a more accurate risk assessment and to offer predictive testing to family members.

Purpose: The majority of gastrointestinal stromal tumors (GIST) are driven by KIT, PDGFRA, or, less commonly, BRAF mutations, and SDH gene inactivation is involved in a limited fraction of gastric lesions. However, about 10% of GISTs are devoid of any of such alterations and are poorly responsive to standard treatments. This study aims to shed light on the molecular drivers of quadruple-negative GISTs.

Article Synopsis
  • The study investigates the role of phosphorylated mTOR (p-mTOR) in triple-negative breast carcinoma (TNBC) and its relation to androgen receptor (AR) expression and disease outcomes.
  • Out of 98 TNBC patients analyzed, about 33% showed positive p-mTOR expression; however, no significant correlation was found between p-mTOR positivity and disease-free survival (DFS) or overall survival (OS).
  • Positive p-mTOR expression was linked to smaller tumor sizes and AR expression, suggesting that targeting both AR and mTOR pathways may be beneficial for certain TNBC patients.

Introduction: The microsatellite-instable gastric cancer subtype, because of its supposed high antigenic potential, is a promising candidate for immunotherapy. We analyzed if the presence of a defective mismatch repair (MMR) system is associated with other markers of immune response and their relationship with outcome in advanced gastric cancer patients.

Methods: We analyzed the relationship between clinical outcome and MMR status, the presence of tumor-infiltrating lymphocytes (TIL), lymphocytosis, and neutrophil-to-lymphocyte ratio (NLR) in metastatic gastric cancer patients treated with a chemotherapy doublet in the first-line setting.

Background: Lynch syndrome (LS) is the most common hereditary colorectal cancer (CRC) syndrome, caused by germline mutations in MisMatch Repair (MMR) genes, particularly in MLH1, MSH2 and MSH6. Patients with LS seem to have a more favourable prognosis than those with sporadic CRC, although the prognostic impact of different mutation types is unknown. Aim of our study is to compare survival outcomes of different types of MMR mutations in patients with LS-related CRC.

Purpose: The discovery of Imatinib mesylate (Gleevec®) has revolutionized the treatment of GIST, increasing diseasefree survival (DFS) after complete surgical resection of a primary localized GIST and extending overall survival in metastatic disease. The definition of an accurate prognostic system is critical for the therapeutic decision making process. In literature, there are three main prognostic criteria F/NIH consensus, AFIP standards and modified NIH standards.

Background: There is a growing body of evidence that immune response plays a large role in cancer outcome. The neutrophil to lymphocyte ratio (NLR) has been used as a simple parameter of systemic inflammation in several tumors. The purpose was to investigate the association between pre-treatment NLR, disease-free survival and overall survival in patients with early triple negative breast cancer (TNBC).

Background: Triple-negative breast cancers (TNBC) are characterized by aggressive tumour biology resulting in a poor prognosis. Androgen receptor (AR) is one of newly emerging biomarker in TNBC. In recent years, ARs have been demonstrated to play an important role in the genesis and in the development of breast cancer, although their prognostic role is still debated.

Objectives: To evaluate the short-term efficacy of muscle shortening manoeuvre (MSM), by inducing an increase in strength of the shoulder muscles, for the treatment of shoulder impingement syndrome (SIS).

Methods: Sixty subjects (mean age: 58.6 years) with SIS were assigned to one of 3 different treatment interventions: 1) MSM: a series of fast accelerations in the upward direction was applied to the upper limb that was also submitted to forces acting in the opposite direction (added mass); 2) traditional physiotherapeutic technique: scapulothoracic gliding; 3) simple traction: the added mass was applied to the limb without the series of fast accelerations.

Nearly one-third of the identified MSH6 germline mutations deal with single amino acid substitutions. For an effective genetic counselling it is necessary to clearly elucidate by functional tools the specific sub-processes underlying the mismatch repair (MMR) misfunctioning in MSH6 non-truncating mutants. Since the MMR repair pathway occurs in the nucleus, we suppose the impairment of MutSα nuclear trafficking to be a possible Lynch syndrome susceptibility causative mechanism.

Single base substitutions can lead to missense mutations, silent mutations or intronic mutations, whose significance is uncertain. Aberrant splicing can occur due to mutations that disrupt or create canonical splice sites or splicing regulatory sequences. The assessment of their pathogenic role may be difficult, and is further complicated by the phenomenon of alternative splicing.

Hereditary Non-Polyposis Colorectal Cancer (HNPCC) is associated with germline mutations in one of several MisMatch Repair (MMR) genes. An increasing proportion (20-25%) of the reported MSH2 variants consists of single amino-acid substitution with uncertain disease-causing significance. The present study was undertaken to functionally characterize 3 MSH2 nontruncating variants: p.

Gastrointestinal Stromal Tumors (GISTs) are the most common mesenchimal tumors of the gastrointestinal tract. Such tumors usually have activating mutations in either KIT (75-80%) or Platelet Derived Growth Factor Receptor alpha (PDGFRa) (5-10%) which lead to ligand-independent signal transduction. Targeting these activated proteins with Imatinib mesylate, a small-molecule kinase inhibitor, has proven useful in the treatment of recurrent or metastatic GISTs.

Background: Complete surgical resection of gastric cancer is potentially curative, but long-term survival is poor.

Methods: Patients with histologically proven adenocarcinoma of the stomach of stages IB, II, IIIA and B, or IV (T4N2M0) and treated with potentially curative surgery were randomly assigned to follow-up alone or to intravenous treatment with four cycles (repeated every 21 days) of PELF (cisplatin [40 mg/m(2), on days 1 and 5], epirubicin [30 mg/m(2), days 1 and 5], L-leucovorin [100 mg/m(2), days 1-4], and 5-fluorouracil [300 mg/m(2), days 1-4] in a hospital setting. Frequencies and severity of adverse events were determined.
