This study aims to systematically investigate somatic mutations in breast cancer patients from Latin America to gain a better understanding of tumor biology in the region.

An overview of resistance to chemotherapy in osteosarcoma and future perspectives.

Osteosarcoma (OS) is the most common type of bone sarcoma. Despite the availability of multimodal treatment with surgery and chemotherapy, the clinical results remain unsatisfactory. The main reason for the poor outcomes in patients with OS is the development of resistance to methotrexate, cisplatin, doxorubicin, and ifosfamide.

and Gene Variants Are Associated With Severe Outcomes of COVID-19 in Men.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is responsible for the current coronavirus disease 2019 (COVID-19) pandemic, affecting more than 219 countries and causing the death of more than 5 million people worldwide. The genetic background represents a factor that predisposes the way the host responds to SARS-CoV-2 infection. In this sense, genetic variants of and could explain the observed interindividual variability to COVID-19 outcomes.

Prospective Study of Fertility Preservation in Young Women With Breast Cancer in Mexico.

Background: Despite the risk of treatment-related infertility, implementation of fertility-preservation (FP) strategies among young patients with breast cancer is often suboptimal in resource-constrained settings such as Mexico. The "Joven & Fuerte: Program for Young Women With Breast Cancer" strives to enhance patient access to supportive care services, including FP measures through alliances with assisted-reproduction units and procurement of coverage of some of these strategies. This study describes patients from Joven & Fuerte who have preserved fertility, and assesses which characteristics were associated with the likelihood of undergoing FP.

Adjuvant endocrine therapy for premenopausal women with breast cancer: Patient adherence and physician prescribing practices in Mexico.

Methods: Premenopausal women with stage 0-III hormone-sensitive breast cancer and receiving adjuvant ET during the past 1-5 years were identified in three Mexican referral centers.

Improving Collection of Real-World Data: The Experience of the Joven & Fuerte Prospective Cohort for Mexican Young Women With Breast Cancer.

The prospective collection of clinical data can generate detailed information on heterogeneous populations. This article reviews the strengths and limitations of the collection of real-world data and provides insight into the feasibility of routine collection of high-quality evidence even in a resource-constrained setting. The acquisition of high-quality data to assess the clinical and psychosocial needs of young Mexican patients with breast cancer has been enhanced through the use of preplanned, standardized data definitions and instrumentation to provide internally and externally comparable results, optimization of data collection with web-based surveys, engagement of participants to minimize missing data, and routine review for data consistency.

Acellular fraction from malignant effusions has cytotoxicity in breast cancer cells.

Malignant ascites (MA) and malignant pleural effusion (MPE) are frequently developed in patients with metastatic cancer; however, the biological properties of these fluids have not been clarified. The present study explored the biological role of a low molecular fraction derived from malignant effusions on the activation of peripheral blood mononuclear cells and on the proliferation of breast cancer cells and fibroblast 55x cells. A <10-kDa fraction from effusions of 41 oncological patients and 34 individuals without cancer was purified, and its potential role in inhibiting nitric oxide (NO) production on lipopolysaccharide (LPS)-stimulated peripheral blood mononuclear cells was explored, as well as its cytotoxicity on MCF-7 breast cancer cells and fibroblast 55x cells.

NLRP3 Inflammasome: The Stormy Link Between Obesity and COVID-19.

Several countries around the world have faced an important obesity challenge for the past four decades as the result of an obesogenic environment. This disease has a multifactorial origin and it is associated with multiple comorbidities including type 2 diabetes, hypertension, osteoarthritis, metabolic syndrome, cancer, and dyslipidemia. With regard to dyslipidemia, hypertriglyceridemia is a well-known activator of the NLRP3 inflammasome, triggering adipokines and cytokines secretion which in addition induce a systemic inflammatory state that provides an adequate scenario for infections, particularly those mediated by viruses such as HIV, H1N1 influenza, and SARS-CoV-2.

Correction to: Afatinib is active in osteosarcoma cell lines.

The title of the article is incorrectly published in the original article. The correct article title is "Afatinib is active in osteosarcoma cell lines".

Afatinib is active in osteosarcoma in osteosarcoma cell lines.

Purpose: Osteosarcoma is the most common bone tumor, mainly affecting adolescents and young adults, and metastatic disease has poor outcomes with a dismal overall survival. Currently, chemotherapy is the standard of care with limited results, finding that new therapies could improve these outcomes. Preclinical and clinical studies have suggested a possible important role of ErbB pathway aberrations in osteosarcoma etiology.

Communication Challenges Among Oncologists in Mexico.

Prognostic significance of neutrophil-to lymphocyte ratio and platelet-to lymphocyte ratio in older patients with metastatic colorectal cancer.

Unlabelled: Aging is associated with a higher risk of cancer, >70% of cancer-related deaths occur in aged patients; however, this population is underrepresented in clinical trials, therefore, clinical information regarding this age group is rather limited.

Objectives: Neutrophil-to lymphocyte ratio (NLR) and platelet-to lymphocyte ratio (PLR) have been described as biomarkers in cancer, thus, we have assessed their impact in an aged cohort of patients with metastatic colorectal cancer (mCRC).

Patients And Methods: 110 patients with a mean age of 72.

Predictive value of vrk 1 and 2 for rectal adenocarcinoma response to neoadjuvant chemoradiation therapy: a retrospective observational cohort study.

Background: Neoadjuvant chemoradiotherapy (NACRT) followed by surgical resection is the standard therapy for locally advanced rectal cancer. However, tumor response following NACRT varies, ranging from pathologic complete response to disease progression. We evaluated the kinases VRK1 and VRK2, which are known to play multiple roles in cellular proliferation, cell cycle regulation, and carcinogenesis, and as such are potential predictors of tumor response and may aid in identifying patients who could benefit from NACRT.

Focal adhesion kinase: predictor of tumour response and risk factor for recurrence after neoadjuvant chemoradiation in rectal cancer.

Rectal cancer represents about 30% of colorectal cancers, being around 50% locally advanced at presentation. Chemoradiation (CRT) followed by total mesorectal excision is the standard of care for these locally advanced stages. However, it is not free of adverse effects and toxicity and the complete pathologic response rate is between 10% and 30%.
