Evolving standards and future directions for systemic therapies in cervical cancer.

Several groundbreaking clinical trials with the potential to transform the management paradigm of both locally advanced and persistent, recurrent, or metastatic cervical cancers have been presented in 2023. This review describes the reported data from INTERLACE and KEYNOTE-A18 in the locally advanced setting, as well as BEATcc, innovaTV 301 and DESTINY-PanTumor02 for advanced disease. The practice implications of their positive results are interpreted in the context of global health considerations, and updated treatment algorithms are proposed.

The cardioprotective potential of sodium-glucose cotransporter 2-inhibitors in breast cancer therapy-related cardiac dysfunction - A systematic review.

Background: Sodium-glucose cotransporter 2-inhibitors (SGLT2i) improve cardiovascular outcomes including reduction in risk of first hospitalisation for heart failure (HF), worsening HF and cardiovascular death regardless of HF or diabetes mellitus (DM) status. It is not known whether SGLT2i can prevent the development of incident HF or reduce the risk of HF in patients receiving trastuzumab with or without other concurrent anti-HER2 agent or sequential anthracycline for treatment of HER2 positive breast cancer. Patients with active malignancy or recent history of malignancy were excluded from participating in the main cardiovascular outcome trials involving SGLT2i.

Emerging systemic therapy options beyond CDK4/6 inhibitors for hormone receptor-positive HER2-negative advanced breast cancer.

Endocrine therapy (ET) with cyclin-dependent kinase 4/6 inhibitor (CDK4/6i) is currently the standard first-line treatment for most patients with hormone receptor (HR) positive, human epidermal growth factor receptor (HER2) negative advanced breast cancer. However, resistance to ET and CDK4/6i inevitably ensues. The optimal post-progression treatment regimens and their sequencing continue to evolve in the rapidly changing treatment landscape.

CRISPR-Cas9 screening identifies an IRF1-SOCS1-mediated negative feedback loop that limits CXCL9 expression and antitumor immunity.

CXCL9 expression is a strong predictor of response to immune checkpoint blockade therapy. Accordingly, we sought to develop therapeutic strategies to enhance the expression of CXCL9 and augment antitumor immunity. To perform whole-genome CRISPR-Cas9 screening for regulators of CXCL9 expression, a CXCL9-GFP reporter line is generated using a CRISPR knockin strategy.

Development and pilot testing of a decision aid for navigating breast cancer survivorship care.

Background: The predominant oncologist-led model in many countries is unsustainable to meet the needs of a growing cohort of breast cancer survivors (BCS). Despite available alternative models, adoption rates have been poor. To help BCS navigate survivorship care, we aimed to systematically develop a decision aid (DA) to guide their choice of follow-up care model and evaluate its acceptability and usability among BCS and health care providers (HCPs).

Differences in Practitioner Experience, Practice Type, and Profession in Attitudes Toward Growing Contact Lens Practice.

Objective: To investigate eye care practitioners' attitudes and perceptions toward potential interventions that can enhance contact lens (CL) practice across the world, and how this is influenced by their practice setting.

Methods: A self-administered, anonymized survey was constructed in English and then forward and backward translated into six more languages. The survey was distributed online via social media platforms and mailing lists involving reputed international professional bodies.

Disparities in Access to Systemic Treatment for Breast Cancer in Thailand and Major Asian Territories.

Purpose: Breast cancer (BC) treatment has shifted from chemotherapy to targeted therapy. Several targeted agents have demonstrated an improvement in survival. Given that national healthcare resources were correlated with the cancer mortality-to-incidence ratio, we compared access to BC drugs in Thailand with that in other Asian countries.

Fomite Transmission Follows Invasion Ecology Principles.

The invasion ecology principles illustrated in many ecosystems have not yet been explored in the context of fomite transmission. We hypothesized that invaders in fomite transmission are trackable, are neutrally distributed between hands and environmental surfaces, and exhibit a proximity effect. To test this hypothesis, a surrogate invader, Lactobacillus delbrueckii subsp.

Fatty acid oxidation is a druggable gateway regulating cellular plasticity for driving metastasis in breast cancer.

Cell state transitions control the functional behavior of cancer cells. Epithelial-to-mesenchymal transition (EMT) confers cancer stem cell-like properties, enhanced tumorigenicity and drug resistance to tumor cells, while mesenchymal-epithelial transition (MET) reverses these phenotypes. Using high-throughput chemical library screens, retinoids are found to be potent promoters of MET that inhibit tumorigenicity in basal-like breast cancer.

A Histone Deacetylase Inhibitor, Panobinostat, Enhances Chimeric Antigen Receptor T-cell Antitumor Effect Against Pancreatic Cancer.

Purpose: In this article, we describe a combination chimeric antigen receptor (CAR) T-cell therapy that eradicated the majority of tumors in two immunocompetent murine pancreatic cancer models and a human pancreatic cancer xenograft model.

Experimental Design: We used a dual-specific murine CAR T cell that expresses a CAR against the Her2 tumor antigen, and a T-cell receptor (TCR) specific for gp100. As gp100 is also known as pMEL, the dual-specific CAR T cells are thus denoted as CARaMEL cells.

Opportunities and threats to contact lens practice: A global survey perspective.

Aim: To understand the views of contact lens (CL) practitioners across the globe regarding what they perceive as opportunities and threats in CL practice.

Methods: A self-administered anonymised questionnaire, constructed in English and translated in six more languages, was distributed through reputed international professional bodies and academic institutions worldwide. The questionnaire included items on demographic characteristics, type of practice, and questions designed to explore practitioners' perspective on the future of their CL practice over the next five years.

MAIT cells regulate NK cell-mediated tumor immunity.

The function of MR1-restricted mucosal-associated invariant T (MAIT) cells in tumor immunity is unclear. Here we show that MAIT cell-deficient mice have enhanced NK cell-dependent control of metastatic B16F10 tumor growth relative to control mice. Analyses of this interplay in human tumor samples reveal that high expression of a MAIT cell gene signature negatively impacts the prognostic significance of NK cells.

Analysis of efficacy of intervention strategies for COVID-19 transmission: A case study of Hong Kong.

By the end of February 2021, COVID-19 had spread to over 230 countries, with more than 100 million confirmed cases and 2.5 million deaths. To control infection spread with the least disruption to economic and societal activities, it is crucial to implement the various interventions effectively.

Cellular networks controlling T cell persistence in adoptive cell therapy.

The antitumour activity of endogenous or adoptively transferred tumour-specific T cells is highly dependent on their differentiation status. It is now apparent that less differentiated T cells compared with fully differentiated effector T cells have better antitumour therapeutic effects owing to their enhanced capacity to expand and their long-term persistence. In patients with cancer, the presence of endogenous or adoptively transferred T cells with stem-like memory or precursor phenotype correlates with improved therapeutic outcomes.

Cost-effectiveness of olaparib versus routine surveillance in the maintenance setting for patients with -mutated advanced ovarian cancer after response to first-line platinum-based chemotherapy in Singapore.

Objective: To evaluate the cost-effectiveness of olaparib as a maintenance treatment versus routine surveillance (RS) in patients with mutated (m) advanced ovarian cancer (OC) following response to first-line platinum-based chemotherapy in Singapore.

Methods: A 4-health state partitioned survival model was developed to simulate the lifetime (50 years) incremental cost-effectiveness ratio (ICER) of olaparib versus RS from a healthcare payer perspective. Progression-free survival, time to second disease progression, and overall survival were estimated using SOLO-1 data and extrapolated beyond the trial period using parametric survival models.

Early Outcomes of a National Cancer Center's Strategy Against COVID-19 Executed Through a Disease Outbreak Response Taskforce.

Purpose: We present the strategy of a comprehensive cancer center organized to make operations pandemic proof and achieve continuity of cancer care during the COVID-19 pandemic.

Methods: Disease Outbreak Response (DORS) measures implemented at our center and its satellite clinics included strict infection prevention, manpower preservation, prudent resource allocation, and adaptation of standard-of-care treatments. Critical day-to-day clinical operations, number of persons screened before entry, staff temperature monitoring, and personal protection equipment stockpile were reviewed as a dashboard at daily DORS taskforce huddles.

Impact of Cryotherapy on Sensory, Motor, and Autonomic Neuropathy in Breast Cancer Patients Receiving Paclitaxel: A Randomized, Controlled Trial.

We conducted a randomized controlled trial evaluating the efficacy and tolerability of cryotherapy in preventing chemotherapy-induced peripheral neuropathy (CIPN) in patients with early breast cancer receiving neo/adjuvant weekly paclitaxel. Patients were recruited from the National Cancer Centre Singapore and randomized (1:1) to receive either cryotherapy or usual care. Cryotherapy was applied as frozen gloves and socks on all extremities from 15 min before paclitaxel until 15 min post-infusion every cycle.

Integrating immunotherapy in the (neo)adjuvant setting of early breast cancer.

Purpose Of Review: Breast cancer is a relative latecomer in the success story of immuno-oncology. In this review, we focus on the preclinical and clinical lines of evidence to justify the evaluation of immune checkpoint inhibition (ICI) for the curative-intent treatment of breast cancer, the latest and ongoing trials of (neo)adjuvant immunotherapy, and practical considerations in clinical practice associated with this new treatment paradigm.

Recent Findings: Insights from the immunobiology of breast cancer have paved the way for the new frontier of immunotherapy in this malignancy, starting from advanced stages and moving onto curable cases.

Enhancing chimeric antigen receptor T-cell immunotherapy against cancer using a nanoemulsion-based vaccine targeting cross-presenting dendritic cells.

Objectives: Adoptive transfer of chimeric antigen receptor (CAR)-modified T cells is a form of cancer immunotherapy that has achieved remarkable efficacy in patients with some haematological cancers. However, challenges remain in CAR T-cell treatment of solid tumours because of tumour-mediated immunosuppression.

Methods: We have demonstrated that CAR T-cell stimulation through T-cell receptors (TCRs) can generate durable responses against solid tumours in a variety of murine models.
