Nearly all cervical cancers are caused by persistent high-risk human papillomavirus (hrHPV) infection. There are 14 recognized hrHPV genotypes (HPV 16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59, 66, and 68), and hrHPV genotypes 16 and 18 comprise approximately 66% of all cases worldwide. An additional 15% of cervical cancers are caused by hrHPV genotypes 31, 33, 45, 52, and 58. Screening patients for hrHPV as a mechanism for implementation of early treatment is a proven strategy for decreasing the incidence of HPV-related neoplasia, cervical cancer in particular. Here, we present population data from an HPV screening initiative in Kosovo designed to better understand the prevalence of the country’s HPV burden and local incidence of cervical cancer by hrHPV genotype. Nearly 2000 women were screened for hrHPV using a real-time polymerase chain reaction (real-time PCR) assay followed by melt curve analysis to establish the prevalence of hrHPV in Kosovo. Additionally, DNA was extracted from 200 formalin-fixed, paraffin embedded cervical tumors and tested for hrHPV using the same method. Cervical screening samples revealed a high prevalence of hrHPV genotypes 16 and 51, while cervical cancer specimens predominantly harbored genotypes 16, 18, and 45. This is the first comprehensive screening study for evaluating the prevalence of hrHPV genotypes in Kosovo on screening cervical brush samples and cervical neoplasms. Given the geographic distribution of hrHPV genotypes and the WHO’s global initiative to eliminate cervical cancer, this study can support and direct vaccination efforts to cover highly prevalent hrHPV genotypes in Kosovo’s at-risk population.

Evaluation of HER2 (ERBB2) gene amplification or protein expression is standard of care in breast (BR) and advanced stage gastro-oesophageal cancers to identify patients eligible for anti-HER2 therapies. Here, we evaluate a rapid fluorescence in situ hybridisation (FISH) technology (HER2 instant quality (IQ) FISH pharmDx Kit) for detection of HER2 in patients with BR and gastro-oesophageal cancer using 30 FFPE samples that had been previously evaluated with the PathVysion HER2 DNA Probe Kit. Cases were scored as positive (HER2:CEN-17 ≥2.0), negative (HER2:CEN-17 <2.0) or equivocal according to the ASCO/CAP 2013 BR cancer guidelines. Ten samples were positive for HER2 amplification while 20 were negative; none were equivocal. The IQ FISH was able to detect low level amplification (HER2:CEN-17 ratio 2.4). The HER2 IQ FISH pharmDx Kit is a FDA approved kit that offers a rapid turnaround time (approximately 3.5 h) and in our laboratory was 100% concordant with prior PathVysion results.
