Dedifferentiated liposarcoma (DDL), exhibiting divergent heterologous differentiation, is a rare entity with a variable reported incidence. These tumors typically arise in the retroperitoneum, often attaining substantial size and presenting at advanced stages, thereby posing significant diagnostic and therapeutic challenges. We report a rare case of recurrent DDL with dual heterologous differentiation—osteosarcomatous and chondrosarcomatous—in an elderly male initially presenting with symptoms m

Port-site metastasis after laparoscopic cholecystectomy in patients with gallbladder adenocarcinoma is an uncommon but serious concern in oncology. This disease is often challenging because of its delayed onset and the subsequent impact on prognosis. In this case, a 42-year-old woman developed a metastasis at the epigastric port site, 6 years following her laparoscopic cholecystectomy for gallbladder adenocarcinoma. The metastasis appeared as an ulcerative mass with features of squamous differen

Due to the widespread nature of breast cancer and its significant impact on the quality of life for those affected, this study aimed to evaluate how palliative care education affects the quality of life of women with breast cancer. In this clinical trial, 46 breast cancer patients were randomly assigned to either an intervention group or a control group. While the control group received standard care, the intervention group participated in 4 weeks of specialized palliative care training. The Mis

Angiogenesis is a key factor in cancer progression, which is influenced by the expression of VEGFR-1, VEGFR-2, and VEGFR-3. Several therapeutic agents, including axitinib, regorafenib, cediranib, and sorafenib, are commonly used in treating cancer, although they can cause side effects such as thrombocytopenia and leukopenia. The current study sought to evaluate how bicyclo derivatives (1-27) interact with VEGFR-1, VEGFR-2, and VEGFR-3, using the 3hng, 2oh4, and 4sbj proteins, along with axitinib

Oral cancer, a malignant growth originating in the tissues of the oral cavity, ranks as the eighth most common cancer globally. Its high mortality rate is largely attributed to diagnoses occurring at advanced stages. Although histological examination remains the gold standard of diagnostic, it necessitates invasive tissue sampling. In contrast, liquid biopsy has recently gained attention as a non-invasive and promising alternative for the diagnosis of oral cancer. This method analyzes tumor-deri

Access to accurate data concerning gynecological malignancies plays a critical role in effective health planning and policymaking. To date, no study has specifically examined the burden of gynecological cancer within the region of Tabuk, Saudi Arabia. This study sought to address that gap by evaluating its prevalence. A retrospective analysis was conducted at King Fahd Specialists Hospital, one of the four randomly selected main healthcare institutions in Tabuk City, Kingdom of Saudi Arabia. The

Merkel cell carcinoma (MCC) is an aggressive form of skin cancer that usually occurs in older individuals, often with a history of prolonged sun exposure. This rare malignancy has been associated with various factors, including ultraviolet light, compromised immune function, and the presence of the Merkel cell polyomavirus (MCPyV). Despite ongoing discussions regarding the origin of the cancer cells, this tumor exhibits characteristics similar to the Merkel cells normally found in the skin, both

Nicotinamide phosphoribosyltransferase (NAMPT) plays a pivotal intracellular role in maintaining nicotinamide adenine dinucleotide (NAD) metabolism, but it is also secreted into the extracellular space, where it functions as a cytokine (eNAMPT). Elevated circulating eNAMPT levels have been reported in inflammatory disorders and malignant diseases. In breast cancer patients, plasma eNAMPT concentrations are increased and show a strong association with disease stage and patient prognosis. On this

The link between specific circulating tumor cell (CTC) phenotypes or genotypes and the effectiveness of neoadjuvant chemotherapy (NAC) has not been clearly established. This investigation aimed to determine whether FTH1 gene–related CTCs (F-CTC), with or without epithelial–mesenchymal transition (EMT) markers, as well as their temporal variations, are associated with NAC outcomes in patients with non-metastatic breast cancer. A total of 120 patients with non-metastatic breast cancer scheduled fo

Triple-negative breast cancer (TNBC) is a highly aggressive form of breast cancer, marked by frequent metastasis and limited targeted therapies. The mechanisms by which epigenomic regulation influences matrix metalloprotease (MMP) activity—and thereby tumor invasiveness—remain incompletely understood. We integrated transcriptomic and chromatin conformation datasets to identify candidate insulator elements that might coordinate MMP gene expression and invasive potential. Using CRISPR/Cas9, we spe

Triple-negative breast cancer (TNBC) is a diverse subtype of breast cancer, constituting about 15–20% of all breast cancer cases. This study highlights KLHL29, an under-researched gene within the Kelch-like gene family, as an important tumor suppressor that influences chemoresistance in TNBC. Compared to adjacent normal tissues, KLHL29 expression was significantly reduced in breast cancer tissues, and lower levels of KLHL29 correlated with poor prognosis. Overexpression of KLHL29 inhibited, whil

CD73 functions as an ecto-enzyme that converts extracellular ATP (eATP), released under stress by tumor cells, into immunosuppressive adenosine (ADO). Many solid tumors exploit CD73 overexpression to evade immune responses, positioning it as an immune checkpoint target. Antibodies such as oleclumab are currently being tested in clinical trials. However, standard monospecific CD73 antibodies may affect normal tissues due to widespread CD73 expression, limiting tumor selectivity. Hence, strategies

Aberrant phosphorylation in cancer cells results in the selective presentation of phosphorylated peptides by MHC molecules. Peptides bound to HLA-A02:01 demonstrate greater stability compared to their nonphosphorylated forms, which may enhance immune recognition. However, it remains uncertain if phosphopeptides displayed by other common alleles share similar structural or immunogenic traits. To investigate this, we analyzed the identity, structure, and immunogenic potential of phosphopeptides pr

Retrospective evidence has suggested that removing the primary breast tumor in patients diagnosed with de novo metastatic breast cancer (MBC) might improve outcomes, yet randomized controlled trials (RCTs) have produced inconsistent findings. This analysis aimed to determine whether surgery of the primary tumor extends survival in this setting. We conducted a systematic literature search to identify RCTs comparing surgical excision of the primary breast tumor with no surgery in patients presenti

Previous research indicated a gradual reduction in the levels of S100P-binding protein (S100PBP) during the progression of pancreatic ductal adenocarcinoma (PDAC). In this study, we show that the loss of S100PBP contributes to the transformation of pancreatic cells into oncogenic forms. Both computational and laboratory analyses revealed that deregulation of S100PBP expression impacts several genes involved in the regulation of the cytoskeleton, cell movement, and survival. Overexpression of S10
