Fractal structures in nature offer a unique "fractal contact mode" that guarantees the efficient working of an organism with an optimized style. Fractal nanostructured biointerfaces have shown great potential for the ultrasensitive detection of disease-relevant biomarkers from small biomolecules on the nanoscale to cancer cells on the microscale. This review will present the advantages of fract...

As part of CALIPER program, a national research initiative aimed at closing the gaps in pediatric reference intervals, I sought to develop a database of covariate-stratified reference intervals in children for 11 circulating tumor markers in accordance with CLSI C28-A3 guidelines. Healthy children from birth to 18 years were recruited to participate in CALIPER and serum samples from 400-700 sub...

AIM OF THE STUDY The available data on serum leptin levels in ovarian cancer present contradictory results. The majority of authors report lower leptin levels in those patients in comparison to healthy individuals. However, there is no data regarding leptin concentrations during therapy in women with primary epithelial ovarian cancer. MATERIAL AND METHODS Blood samples were collected at the t...

OBJECTIVE Patient characteristics, CA125 level and two-dimensional (2D) ultrasonography can be used to predict the probability of malignancy of an ovarian mass. Three-dimensional (3D) ultrasonography might also contribute to the prediction of malignancy. We evaluated whether addition of 3D features to a diagnostic model could improve the discriminative capacity of the model. METHODS This mult...

Our objective was to evaluate the diagnostic value of squamous cell carcinoma antigen (SCC-ag) and cancer antigen (CA) 125 serum tumor markers for the detection of cervical cancer. Abnormal SCC-ag(>1.5 ng/mL) and CA125 (>35 U/mL) levels were found in 64.2% and 18.9% of a series of SCC patients and in 25.0% and 42.6% of adenocarcinoma (AC) patients. The SCC-ag and CA 125 markers appeared rather ...

OBJECTIVE Meigs' syndrome presenting as an ovarian tumor with elevated serum cancer antigen 125 (CA 125) levels is unusual. Only 37 cases have been reported, including three cases of ovarian sclerosing stromal tumor (SCT). Many reports have suggested that the presence of ascites is the major factor inducing mesothelial expression of CA 125. CASE REPORT An 18-year-old woman presented with mass...

Synchronous serum specimens from the systemic and portal circulations of 43 patients with gastrointestinal cancer were assayed for levels of carcinoembryonic antigen, CA 19-9, and CA 125 tumor-associated antigens. The number of patients having a mean ratio of portal to systemic levels greater than 1 and the observed quantity of tumor-associated antigens were significant for carcinoembryonic ant...

BACKGROUND Cancer antigen 125 (CA 125), a widely used tumor marker for monitoring epithelial ovarian cancer, is also found to be raised in non-gynecological tumors and non malignant disease involving peritoneum. We report a case of non-Hodgkin's lymphoma who presented with peritoneal and pleural effusions with a very high level of serum CA 125. CASE Fifty four years female presented with gros...

Veno-occlusive disease (VOD) is a potentially lethal complication of patients undergoing bone marrow transplantation (BMT). The diagnosis of VOD is currently based on clinical signs and unspecific laboratory findings. CA 125 is an oncofetal antigen used as a tumor marker in various malignancies, especially in those originating from the female reproductive tract or gastrointestinal organs, where...

BACKGROUND Little is known about the correlations between tumor markers (TMs), breast cancer subtypes, site(s) of metastasis and prognosis. METHODS Women diagnosed with metastatic breast cancer were included. Breast cancer subtypes were defined as LuminalA, LuminalB, LuminalHer2, Her2, Basal and non-Basal triple negative (TN). Levels of elevation of TM values [cancer antigen 15-3 (CA 15-3), c...
