Background: The current embryo selection methods rely on subjective grading of embryo morphology or a real-time monitoring of the embryonic development and assessment of multiple quantitative endpoints. Even up to 40% of morphologically normal embryos harbour aneuploidies. Preimplantation genetic testing (PGT) is a technology, which gives opportunity to identify euploid embryos before implantation.
Aims: This study seeks to determine the role of PGT in poor prognosis patients, i.e., patients with advanced maternal age (AMA) (maternal age ≥35 years), recurrent pregnancy loss (RPL) (miscarriages ≥2) and recurrent implantation failures (RIFs) ( fertilisation failures ≥3).
Study Setting And Design: A retrospective case-control study was done on a group of patients who underwent intracytoplasmic sperm injection for the indications of AMA, RPL and RIF.
Materials And Methods: In 33 cases who opted for PGT, day 5 blastocysts were subjected to trophectoderm biopsy with the help of next-generation sequencing. Euploid blastocyst was transferred in hormone replacement cycle at a later date. In 154 controls, blastocyst transfer was done based on morphological grading. Pregnancy outcomes are compared in terms of implantation rate, pregnancy rate, miscarriage rate and multiple pregnancy rate.
Statistical Analysis: Chi-square test was used for comparisons between the study groups with respect to percentage. < 0.05 was considered statistically significant.
Results: The highest aneuploidy rate was found in embryos with AMA. Implantation rate was found to be statistically significantly higher in the PGT group as compared to the non-PGT group. However, take-home baby rates were not improved by PGT. There were less number of mean embryos transferred in the PGT group and lower multiple pregnancy rate.
Conclusions: With the application of PGT, embryo selection rates and implantation rates improved in poor prognosis patients.

Objective: TRIB3 has been confirmed to participate in and regulate biological metabolic activities in head and neck tumors such as nasopharyngeal carcinoma and oropharyngeal carcinoma, so the purpose of this study was to explore whether there is a correlation between TRIB3 and Laryngeal Squamous Cell Carcinoma (LSCC) and to preliminarily explore the biological characteristics of TRIB3 in LSCC.
Methods: TRIB3 expression in the LSCC was analyzed based on The Cancer Genome Atlas (TCGA) database. CCK-8 assay, Colony Formation Assay, wound healing assay, and Transwell assay were performed to investigate the roles of TRIB3 in the proliferation, invasion and metastasis of LSCC.

Background: Ras-GTPase-activating protein (GAP)-binding protein 1 (G3BP1) emerges as a pivotal oncogenic gene across various malignancies, notably including nasopharyngeal carcinoma (NPC). The use of automated image analysis tools for immunohistochemical (IHC) staining of particular proteins is highly beneficial, as it could reduce the burden on pathologists. Interestingly, there have been no prior studies that have examined G3BP1 IHC staining using digital pathology.

Metastatic uveal melanoma (UM) patients often initially present with limited symptoms despite a poor prognosis, complicating communication with patients and caregivers. Early Together (NCT04728113) is a randomized Phase III trial that integrates early palliative care through systematic joint visits involving the palliative care team and the medical oncologist, compared with standard oncological care, in 162 metastatic UM patients beginning systemic treatment. This collaboration aims to enhance patient functioning, improve quality of life and facilitate coping mechanisms.

Subungual melanoma accounts for 1.9% of cutaneous melanomas. Amelanotic cases, comprising 15-25%, poses a significant diagnostic challenge because it can be misdiagnosed as other traumatic, inflammatory, or neoplastic conditions.

In gastric cancer, the relationship between human epidermal growth factor receptor 2 (HER2), the cyclic GMP-AMP synthase-stimulator of the interferon genes (cGAS-STING) pathway, and autophagy remains unclear. This study examines whether HER2 regulates autophagy in gastric cancer cells via the cGAS-STING signaling pathway, influencing key processes such as cell proliferation and migration. Understanding this relationship could uncover new molecular targets for diagnosis and treatment.
