The knowledge about the quality of samples and associated clinical data in biospecimen collections is a premise of clinical research. An electronic biosample register aims to facilitate the discovery of information about biosample collections in a hospital. Moreover, it might improve scientific collaboration and research quality through a shared access to harmonized sample collection description data.

The recently discovered metastasis-associated in colon cancer-1 (MACC1) gene is a key regulator of the HGF/MET pathway. Potential links between genetic variants of the MACC1 gene and survival in breast cancer patients are unknown.

High circulating IGF-1 levels are linked with an increased risk of colorectal and breast cancer. Recently, IGF-1 single nucleotide polymorphisms (SNPs), especially variant rs2946834, have been associated with poor clinical outcome in patients with colorectal cancer.

The aim of the present study was to examine the clinical relevance of the MDM2 SNP309 in ovarian cancer.MDM2 SNP309 genotype was analyzed in 198 patients with primary ovarian cancer.

The clinical relevance of TAp73 and ΔNp73 protein expression has not yet been evaluated in ovarian cancer. TAp73 and ΔNp73 expression was examined using immunohistochemistry and reverse transcription-polymerase chain reaction in 83 and 64 ovarian cancer specimens, respectively.

Materials And Methods: Activated (phosphorylated) p38-MAPK was immunohistochemically assessed in paraffin-embedded tumors obtained at primary debulking surgery from 45 patients treated with gemcitabine for platinum-resistant recurrence. The value of activated p38-MAPK in predicting sensitivity to gemcitabine treatment was statistically evaluated.
