Background: Cylin D1(CCDN1) is an important regulator of the cell cycle whose alterations are thought to be involved in cancer development. There have been many studies indicating CCDN1 amplification or over- expression in a variety of cancer types. In addition to gene amplification, the G870A polymorphism may be related with altered CCDN1 activity, and therefore with cancer development. This hypothesis has been tested in different cancer types but results have been contradictory. We therefore aimed to investigate any relationship between CCDN1 A870G genotypes and laryngeal squamous cell cancer development and progression.
Materials And Methods: A total of 68 Turkish patients with primary laryngeal squamous cell cancer and 133 healthy controls were enrolled. Polymerase chain reaction-restriction fragment length polymorphism analysis was used to determine the CCDN1 genotypes.
Results: No significant association was detected between CCDN1 genotypes and laryngeal squamous cell cancer (LxSCCa) development. Similarly CCDN1 genotypes were not related to clinical parameters of Lx SCCa. However, there was a very significant association between CCDN1 G allele and presence of perineural invasion (p= 0.003; OR: 1.464; CI% 1.073-1.999). CCDN1 G allele frequency was significantly higher in the individuals with perineural invasion (85.7%) when compared to those without (58.5%). The 2 patients who died of disease were both found to possess the GG genotype.
Conclusions: These results pose a controversy in suggesting a protective role of the G allele against LxSCCa development and support the association of CCDN1 gene GG genotype with mortality in patients with LxSCCa.

Myelodysplastic Neoplasm (MDS) is a cancer associated with aging, often leading to acute myeloid leukemia (AML). One of its hallmarks is hypermethylation, particularly in genes responsible for DNA repair. This study aimed to evaluate the methylation and mutation status of DNA repair genes (single-strand - XPA, XPC, XPG, CSA, CSB and double-strand - ATM, BRCA1, BRCA2, LIG4, RAD51) in MDS across three patient cohorts (Cohort A-56, Cohort B-100, Cohort C-76), using methods like pyrosequencing, real-time PCR, immunohistochemistry, and mutation screening.

The incidence of keratinocyte carcinoma (KC) is rising globally, significantly burdening healthcare resources. Treatment options include medical treatment, non-invasive procedures, and surgery, each associated with their distinct benefits and risks. With advanced treatment, the procedures become increasingly invasive for the patients and expensive for the society.

Purpose: To develop and validate an MRI-based model for predicting postoperative early (≤2 years) recurrence-free survival (RFS) in patients receiving upfront surgical resection (SR) for beyond Milan hepatocellular carcinoma (HCC) and to assess the model's performance in separate patients receiving neoadjuvant therapy for similar-stage tumors.
Method: This single-center retrospective study included consecutive patients with resectable BCLC A/B beyond Milan HCC undergoing upfront SR or neoadjuvant therapy. All images were independently evaluated by three blinded radiologists.

Background: Skin cancers, including melanoma and keratinocyte cancers, are among the most common cancers worldwide, and their incidence is rising in most populations. Earlier detection of skin cancer leads to better outcomes for patients. Artificial intelligence (AI) technologies have been applied to skin cancer diagnosis, but many technologies lack clinical evidence and/or the appropriate regulatory approvals.

Background: Parents of children treated for cancer may experience psychological difficulties including depression, anxiety, and posttraumatic stress. Digital interventions, such as internet-administered cognitive behavioral therapy, offer an accessible and flexible means to support parents. However, engagement with and adherence to digital interventions remain a significant challenge, potentially limiting efficacy.
