Is the urinary neutrophil gelatinase-associated lipocalin concentration in children and adolescents with type 1 diabetes mellitus different from that in healthy children?

Introduction: Diabetic kidney disease (DKD) is one of the major microvascular complications of type 1 diabetes mellitus (T1DM). Some studies suggest that changes of renal tubular components emerge before the glomerular lesions thus introducing the concept of diabetic tubulopathy with urinary neutrophil gelatinase-associated lipocalin (uNGAL) as a potential marker of DKD. This concept was not confirmed in all studies.

Association of V600E Mutant Allele Proportion with the Dissemination Stage of Papillary Thyroid Cancer.

The early identification of aggressive forms of cancer is of high importance in treating papillary thyroid cancer (PTC). Disease dissemination is a major factor influencing patient survival. Mutation status of oncogene, V600E, is proposed to be an indicator of disease recurrence; however, its influence on PTC dissemination has not been deciphered.

GENOMICS OF PROSTATE CANCER: CLINICAL UTILITY AND CHALLENGES.

The studying of prostate cancer genomics is important for understanding prostate cancer biology, it can provide clinically relevant stratification into subtypes, the development of new prognostic and predictive markers in the context of precision medicine, and the development of new targeted therapies. Recent studies have provided detailed insight into genomics, epigenomics and proteomics of prostate cancer, both primary and metastatic castration-resistant (mCRPC). Many mutations have been discovered, both those that occur early in the carcinogenesis and progression as well as those responsible for the resistance to therapy occurring later under the influence of treatment.

CHALLENGES IN MANIPULATING IMMUNE SYSTEM TO TREAT PROSTATE CANCER.

First cancer vaccine that was approved for routine therapy was sipuleucel-T for treatment of patients with metastatic castration resistant prostate cancer. However, other immunotherapy drugs evaluated in prostate cancer, particularly immune checkpoint inhibitors, have failed to show therapeutic effect. There are several potential explanations for lack of response of prostate cancer to these drugs.

Quality of life of Croatian breast cancer patients receiving adjuvant treatment--comparison to long-term breast cancer survivors.

Quality of life (QoL) is an important outcome in assessment of breast cancer treatment. Data comparing QoL after different adjuvant treatments and QoL data on long-term survivors are modest. The aim of this study was to compare QoL scores of patients receiving adjuvant treatment with long-term breast cancer survivors, and to correlate QoL scores with clinical data.

Galectin-3 and CD44v6 as markers for preoperative diagnosis of thyroid cancer by RT-PCR.

The aim of the study was to determine the diagnostic value of reverse transcriptase polymerase chain reaction (RT-PCR) analysis of galectin-3 and CD44v6 as markers for preoperative diagnosis of malignancy in lesions of the thyroid. RT-PCR analysis of galectin-3 and CD44v6 expression was performed on RNA isolated from fine-needle aspirates of thyroid lesions from 428 patients. The results were evaluated against the postoperative histopathological diagnosis or definitive cytological diagnosis in cases of nodular goiter and Hashimoto thyroiditis.

Accuracy of fine needle aspiration biopsy with and without the use of tumor markers in cytologically indeterminate thyroid lesions.

We investigated if the use of two tumor markers, galectin-3 and CD44v6, could improve diagnostic accuracy of thyroid fine needle aspiration biopsy (FNAB) in cytologically indeterminate lesions (CIL). 351 patients with CIL [cellular follicular lesion/suspicious follicular neoplasm/suspicious Hürthle cell neoplasm (CFL/sFN/sHCN), Hürthle cell neoplasm (HCN), and follicular neoplasm (FN)] and surgical follow-up were investigated. 251 patients had FNAB diagnoses made without help of tumor markers and the rest of 100 patients had FNAB diagnoses made with a known expression of tumor markers determined by the reverse transcription (RT)-PCR.
