- Aim: To compare the clinical performance of human papillomavirus (HPV) mRNA and DNA assays in postmenopausal women. Materials and Methods: A total of 5,925 postmenopausal women were tested with cytology and the Luminex HPV DNA assay. High risk-HPV-positive women with benign cytology underwent a complimentary HPV mRNA assay (APTIMA). Both assays and the cytological testing were repeated after 12 months. Results: A total of 334 women were found to be high-risk HPV-positive; 272 out of these women met the inclusion criteria. At follow-up, 25 (9.2%) out of the 272 included women had cytological abnormalities. HPV mRNA assay at follow-up had a sensitivity of 84% (95% confidence interval=63.9-95.4%) and a specificity of 60.2% (95% confidence interval=53.7-66.3%; p=0.0003) to detect these lesions. Corresponding values for the HPV DNA assay were 88% (95% confidence interval=68.8-97.4%) and 43.5% (95% confidence interval=37.2-49.4%). Conclusion: The HPV mRNA assay offers a comparable sensitivity but a higher specificity than the HPV DNA assay in detecting precancerous cervical lesions.

- Background/Aim: To compare human papillomavirus (HPV) DNA detection in self-collected vaginal and urine samples with clinician-taken cervical samples in relation to histology. Materials and Methods: Self-collected vaginal, urine and clinician-taken cervical samples were analyzed from 218 women with the Cobas 4800 HPV test (Roche Molecular Diagnostics). Results: The sensitivity for detection of HPV in the vaginal self-sampling test was 96.4% and in urine was 83.9% relative to detection by clinician-taken cervical sample. The vaginal self-sampling and the clinician-taken HPV tests had the same sensitivity of 92.8% (95% confidence interval=86.3-96.8%) and specificity for detection of high-grade squamous intraepithelial lesion (HSIL) and adenocarcinoma in situ (AIS). Detection in urine samples had a sensitivity of 76.3% (95% confidence interval=67.9-84.2%) for HSIL/AIS. Conclusion: The Cobas 4800 HPV test detects high-grade pre-cancerous cervical lesions in self-collected vaginal samples with the same high sensitivity as in clinician-taken cervical samples.

- Background: The malignant brain tumour glioblastoma is a devastating disease that remains a therapeutic challenge. Materials and Methods: Effects of combinations of the US Food and Drug Administation (FDA) approved proteasome inhibitor bortezomib and the histone deacetylase (HDAC) inhibitors vorinostat, valproic acid and sodium phenylbutyrate were studied on primary glioblastoma stem cell lines and conventional glioblastoma cell lines. Cell survival, proliferation and death were analyzed by fluorometric microculture cytotoxicity assay (FMCA), propidium iodide labeling and flow cytometry, and cell cloning through limiting dilution and live-cell bright-field microscopy. Results: Bortezomib and the HDAC inhibitors showed synergistic cell killing at clinically relevant drug concentrations, while the conventional cell lines cultured in serum-containing medium were relatively resistant to the same treatments. Conclusion: These findings of synergistic glioblastoma stem cell killing by bortezomib and three different FDA-approved HDAC inhibitors confirm and expand previous observations on co-operative effects between these classes of drugs.

- Background/aim: Residual disease (RD) after primary debulking surgery (PDS) is a prognostic factor for survival in advanced ovarian cancer (AOC). This study aimed to examine whether the tumor extent affects overall survival (OS) and progression-free survival (PFS) in AOC patients treated with PDS.Patients and methods: A total of 118 patients treated with PDS were included. Age, ECOG score, AOC International Federation of Gynecology and Obstetrics (FIGO) stage, CA-125, RD, peritoneal cancer index (PCI), preoperative imaging (CT-PCI) and macroscopic visualization at the surgery start (S-PCI) were analyzed. Tumor extent was quantified using the PCI, and by CT-PCI and S-PCI. Cox regression, Kaplan-Meier and receiver operating curves (ROC) were performed for survival analyses.Results: S-PCI correlated with both OS (1.067, 95%CI=1.018-1.119, p<0.007) and PFS. Patients exhibiting S-PCI≥18.5, adjusted to age, performance status, and RD, had a two-fold risk of dying (HR=2.070, 95%CI=1.061-4.038, p=0.033) compared those with PCI<18.5. CT-PCI correlated with OS in crude data (1.037, 95%CI=1.005-1.071, p=0.025), but this was not sustained in multivariate analyses. RD of any size doubled the risk of dying (2.177, 95%CI=1.235-3.838, p=0.007).Conclusion: The tumor extent at the beginning of surgery seemed to affect OS in patients with AOC, regardless of the extent of RD at the end of the surgery. PCI above 18.5 doubled the risk of dying of the disease. No difference in major complications was noted in the two groups of patients. CT-PCI seemed to play a prognostic role for PFS; however, it is still to be investigated as a prognostic factor for OS.

- BACKGROUND:Insulin-like growth factor 1 (IGF-1) may influence cellular growth, differentiation and secretion.MATERIAL AND METHODS:Cryosectioned normal human adrenal glands (n = 6), cortical adenoma (n = 21), and carcinoma (n = 17) were stained immunohistochemically for IGF-1 and its receptor, and human adrenocortical cancer cells expressing the receptor were analysed for influences on proliferation.RESULTS:Normal cortical parenchyma generally displayed faint IGF-1 reactivity and intracellular receptor staining. Similar labelling encompassed the adenomas, but only 6 of them were receptor reactive. IGF-1 expression was conspicuous in 11 carcinomas, and 6 of them displayed cell surface receptor reactivity. All aldosterone producing lesions were receptor antibody unreactive. Recombinant IGF-1 dose-dependently stimulated the cell proliferation, and this effect was reversed by the receptor antibody.CONCLUSION:IGF-1 may interact with function and proliferation of the human adrenal cortex with particular reference to cortical carcinomas lacking discernible aldosterone excess.

- Mutations affecting the mechanistic target of rapamycin (MTOR) signalling pathway are frequent in human cancer and have been identified in up to 15% of pancreatic neuroendocrine tumours (NETs). Grade A evidence supports the efficacy of MTOR inhibition with everolimus in pancreatic NETs. Although a significant proportion of patients experience disease stabilization, only a minority will show objective tumour responses. It has been proposed that genomic mutations resulting in activation of MTOR signalling could be used to predict sensitivity to everolimus.PATIENTS AND METHODS: Patients with NETs that underwent treatment with everolimus at our Institution were identified and those with available tumour tissue were selected for further analysis. Targeted next-generation sequencing (NGS) was used to re-sequence 22 genes that were selected on the basis of documented involvement in the MTOR signalling pathway or in the tumourigenesis of gastroenterpancreatic NETs. Radiological responses were documented using Response Evaluation Criteria in Solid Tumours.RESULTS: Six patients were identified, one had a partial response and four had stable disease. Sequencing of tumour tissue resulted in a median sequence depth of 667.1 (range=404-1301) with 1-fold coverage of 95.9-96.5% and 10-fold coverage of 87.6-92.2%. A total of 494 genetic variants were discovered, four of which were identified as pathogenic. All pathogenic variants were validated using Sanger sequencing and were found exclusively in menin 1 (MEN1) and death domain associated protein (DAXX) genes. No mutations in the MTOR pathway-related genes were observed.CONCLUSION: Targeted NGS is a feasible method with high diagnostic yield for genetic characterization of pancreatic NETs. A potential association between mutations in NETs and response to everolimus should be investigated by future studies.

- Malignant pleural mesothelioma (MPM) is a rare but aggressive malignancy mainly localized to the pleura. Malignant mesothelioma grows highly invasive into surrounding tissue and has a low tendency to metastasize. The median overall survival (OS) of locally advanced or metastatic disease without treatment is 4-13 months but, during recent years, improvement in survival has been achieved since treatment for patients with mesothelioma has improved with better palliative care, systemic medical treatment, surgery and improved diagnostics methods. The present review aims at describing available data from randomized trials considering systemic medical treatment for this patient category.

- BACKGROUND/AIM: To discover candidate protein biomarkers in the serum of patients with cervical cancer that differentiate between patients with relapse from those who are tumor-free after primary treatment with (platinum-based chemo-) radiation.PATIENTS AND METHODS: Surface-enhanced laser desorption/ionization time-of-flight mass spectrometry (SELDI-TOF-MS) with cation exchange (CM10) and hydrophobic/reverse-phase (H50) was used to examine 44 serum samples from patients with advanced cervical cancer, primarily treated with (platinum-based chemo-) radiation.RESULTS: Ten candidate biomarkers were identified in the serum of 34 patients. Six candidate markers were elevated in patients with no relapse and four were elevated in patients with relapse [p=0.007-0.11; area under the curve (AUC)=0.70-0.75]. Masses of candidate biomarkers ranged from 2,022 to 116,165 Da.CONCLUSION: Patients with relapse from primary advanced cervical cancer exhibit different serum protein expression profiles from those with no relapse.
