Published: September 2024

Intra-abdominal splenosis is a rare finding which most commonly occurs following traumatic splenectomy. We present a case report of a patient who presented with abdominal pain in which peripancreatic and intrapancreatic lesions were found in the setting of mediastinal lymphadenopathy. Owing to concerns for pancreatic malignancy, we explored these lesions using endoscopic ultrasound with fine-needle biopsy (with rapid on-site evaluation). Ultimately, surgical pathologies revealed the presence of splenic tissues and the diagnosis of pancreatic splenosis.

Introduction: Prostate cancer (PCa) is the commonest urologic cancer worldwide and the leading cause of male cancer deaths in Nigeria. In Nigeria, orchidectomy remains the primary androgen deprivation therapy. Dihydrotestosterone (DHT) is the active prostatic androgen, but its relationship with PCa severity has not been extensively studied in Africa.

The development of resistance remains one of the biggest challenges in clinical cancer patient care and it comprises all treatment modalities from chemotherapy to targeted or immune therapy. In solid malignancies, drug resistance is the result of adaptive processes occurring in cancer cells or the surrounding tumor microenvironment (TME). Future therapy attempts will therefore benefit from targeting both, tumor and stroma compartments and drug targets which affect both sides will be highly appreciated.

Genetic association of lipid-lowering drug target genes with pancreatic cancer: a Mendelian randomization study.

Previous studies have found that dyslipidemia is a risk factor for pancreatic cancer (PC), and that lipid-lowering drugs may reduce the risk of PC. However, it is not clear whether dyslipidemia causes PC. The Mendelian randomization (MR) study aimed to investigate the causal role of lipid traits in pancreatic cancer and to assess the potential impact of lipid-lowering drug targets on pancreatic cancer.
