In this work, biochemical changes in sporadic adenoma during progression to colon cancer have been detected by spectral techniques. It is shown that spectra of all types of adenomas as well as adenocarcinoma have two maxima at 265 ÷ 270 nm and at 330 ÷ 340 nm. The first maximum is primarily defined by tryptophan containing peptides. The second maximum of the spectra is in the main defined by collagen presence in stroma of tumors and normal mucosa. Progression of precancer lesions to advanced cancer leads to increase of NADH concentration impacting on the second maximum of spectra. At the time, the spectra of both AC differ from each other by widths of the second maximum. For well-differentiated AC, the second maximum is wider. It gives reason to suggest that two fluorophores impact on its intensity. These fluorophores can be NADH and vitamin B. Correlation between microscopical and spectral results can allow to use fluorimetry for detail diagnostics and investigation of colon cancer development.

Epithelial ovarian cancer (EOC) is one of the most common causes of cancer-related deaths among women and is associated with age and age-related diseases. With increasing evidence of risks associated with metabolic inflammatory conditions, such as obesity and type 2 diabetes mellitus (T2DM), it is important to understand the complex pathophysiological mechanisms underlying cancer progression and metastasis. Age-related conditions can lead to both genotypic and phenotypic immune function alterations, such as induction of senescence, which can contribute to disease progression. Immune senescence is a common phenomenon in the ageing population, which is now known to play a role in multiple diseases, often detrimentally. EOC progression and metastasis, with the highest rates in the 75–79 age group in women, have been shown to be influenced by immune cells within the “milky spots” or immune clusters of the omentum. As T2DM has been reported to cause T cell senescence in both prediabetic and diabetic patients, there is a possibility that poor prognosis in EOC patients with T2DM is partly due to the accumulation of senescent T cells in the omentum. In this review, we explore this hypothesis with recent findings, potential therapeutic approaches, and future directions.

The appendix anomalies are extremely rare malformations. Preoperative diagnosis of appendiceal duplication is often difficult and usually discovered incidentally during surgery forappendicitis. A clinical case of the development of chronic residual appendicitis in a 32-year-old woman with the abnormality of the vermiform appendix identified duplicity, type A according to the Cave-Wallbridge classification is described. During the first hospitalization, the patient was treated conservatively with a diagnosis of «a dense appendiceal infiltrate»; later, a planned appendectomy was performed. A duplication of the vermiform appendix type A was revealed during the examination of the removed appendix. Histopathological examination detected the underdevelopment of the wall of the accessory vermiform appendix - a complete absence of the outer longitudinal layer of the muscular membrane. The abnormally thin wall of the accessory appendix, as well as the related with it hypoperistalsis provoked the onset of chronic inflammation in the wall, which easily spread to the periappendiceal adipose tissue with the formation of a dense appendiceal infiltrate, which required surgical intervention. Thus, a rare clinical case of duplication of the vermiform appendix type A with forming of appendiceal infiltrate, associated with abnomality of muscular tissue, shown by the surgical findings and corroborated by pathology samples of intestinal tissue has been presented.
