Background: Colorectal cancer (CRC) is the third most diagnosed globally and second leading cause of cancer-related deaths. Despite advancements, metastatic CRC (mCRC) has a five-year survival rate below 20%. Next-generation sequencing (NGS) recommended nowadays to guide mCRC treatment; however, its clinical utility when compared with traditional molecular testing in debated due limited improvement cost-effectiveness concerns. Methods: This retrospective study included patients (≥18 years)...

The multitarget oral tyrosine kinase inhibitor sorafenib is an effective first-line treatment option in unresectable hepatocellular carcinoma. Through its mechanism of action, it has been associated with cardiotoxicity, mainly hypertension, which usually low-grade and well-managed behavioral changes antihypertensor adjustment, if needed. Acute, symptomatic heart failure rarely described. We present the case a patient priors arterial dyslipidemia, type 2 diabetes mellitus, non-alcoholic...

INTRODUCTION: In patients with metastatic colorectal cancer (mCRC) without RAS/BRAF somatic variants, first-line anti-EGFR antibodies plus chemotherapy improve survival. Retreatment of responders rechallenge accumulates less evidence for benefit when compared other available third-line treatments. MATERIAL AND METHODS: A unicentric retrospective cohort wild type (wt) mCRC, treated irinotecan/cetuximab within the definition rechallenge, was selected between 2018 and 2023. Liquid biopsy...

Synchronous primary malignancies are uncommon and represent diagnostic therapeutic challenges, particularly for elderly patients with comorbidities. We report the case of a 78-year-old man distinct adenocarcinomas lung pancreas who was successfully treated curative-intent approach. Initially exhibiting unintentional weight loss, asthenia, gastrointestinal complaints, initial workup, which included computed tomography (CT) positron emission tomography/computed (PET/CT), revealed spiculated...

This case report describes the clinical course, diagnosis, and management of a premenopausal woman with history estrogen receptor (ER)-positive human epidermal growth factor 2 (HER2)-positive early breast cancer (EBC) who developed severe thrombocytopenia. After six years diagnosis EBC (treated curative intent), she presented back pain, significant bruising, menorrhagia. During work-up, laboratory tests revealed thrombocytopenia, imaging studies, including computed tomography scan bone...

The distribution of blood pressure (BP) in children and adolescents remains relatively unknown. Thus, it is imperative to ascertain BP at a young age, which constitutes the main objective this registry.Cross-sectional assessment 5381 Portuguese adolescents, mean age 12.50±3.23 years (4-18 years), body mass index (BMI) 19.65±4.00 kg/m(2) (9.37-60.30 kg/m(2)), mostly male (4519), 12.70±3.16 years, with 862 females, 11.44±3.34 years. heart rate were measured three times after 10-min resting...

<ns4:p>Background Breast cancer frequently leads to reduced work capacity and increased absenteeism among working-age women diagnosed with this condition. In study, we aimed assess the effect of CDK4/6i combined aromatase inhibitors (AIs) or fulvestrant on quality life (QoL) activity in a cohort Portuguese patients hormone receptor-positive/human epidermal growth factor receptor 2-negative (HR+/HER2-) metastatic breast who started treatment regimen. Methods This unicentric prospective...

<title>Abstract</title> Despite advancements in cancer immunotherapy, most lymphomas remain unresponsive to checkpoint inhibitors. P-selectin glycoprotein ligand-1 (PSGL-1), recently identified as a promoter of T cell exhaustion melanoma murine models, has emerged novel immune protein and promising immunotherapeutic target. In this study, we investigated the potential PSGL-1 antibody targeting B-cell lymphoma. Using allogeneic coculture systems, demonstrated that targeted interventions...

Neuroendocrine carcinoma of the cervix (NECC) is a rare and extremely aggressive disease. Treatment options are scarce (mainly consisting platinum-based chemotherapy combinations), randomized controlled trials lacking, leading to very poor prognosis. It prone early metastasis, often with more than one affected site at diagnosis. The lung, liver, brain, bone most frequent sites. We present case 33-year-old female patient no significant medical history. Postcoital bleeding led diagnosis human...

Fibrotic Hypersensitivity Pneumonitis (fHP) often presents a progressive fibrosing (PF) phenotype. Elevated levels of both circulating monocytes and alveolar macrophages have been pointed to play role in the pathogenesis idiopathic pulmonary fibrosis, but no substantive data exists regarding their contribution on PF-HP. We performed multicenter analysis retrospective cohort 210 patients with fHP determine predicting variables early (&lt;2 years) PF phenotype or death. The relationship...
