- Background/Aim: To assess preoperative blood levels of a biomarker panel in relation to the new classification system of epithelial ovarian cancer (EOC) type I and II. Patients and Methods: Preoperative plasma levels of B7-family protein homolog 4 (B7-H4), intact and cleaved soluble urokinase plasminogen activator receptor (suPAR), human epididymis protein 4 (HE4) and cancer antigen 125 (CA125) were analyzed in 350 patients with adnexal lesions. Results: The levels of suPAR(II-III), HE4, CA125 were all higher in EOC II than in EOC I, borderline and benign ovarian tumors. B7-H4 was increased in EOC II compared with benign ovarian tumors. The combination of suPAR(II-III), HE4, CA125 and age in premenopausal women discriminates EOC and borderline tumors from benign tumors to higher accuracy compared to the Risk of Ovarian Malignancy Algorithm (p=0.007). Conclusion: The biomarker panel suPAR(II-III), HE4, CA125 and age in premenopausal women improved discrimination of malignant and benign ovarian tumors. The plasma levels of B7-H4 were increased in patients with EOC II compared to those with benign ovarian tumors.

- In order to survey the side effects after cancer treatment, quality of life data were collected from females in clinical remission. MATERIALS AND METHODS The study was cross-sectional; every patient that visited the outpatient clinic during a period of three months was asked to anonymously complete the EORTC QLQ-C30 questionnaire and five additional specific questions related to gynaecological cancer. RESULTS In total, 235 patients (90%) returned the questionnaire. In general, both the levels of functioning and symptomatology were time-dependent. Patients with short treatment-free intervals reported more problems than the others. When using treatment modality as an independent variable in the statistical calculations, a treatment-related effect on functioning and symptomatology was demonstrated (p < 0.05 to p < 0.001). Patients previously treated with chemotherapy had poorer role- and cognitive functioning and more problems with fatigue, nausea, vomiting, dyspnoea, constipation and financial problems, compared with those not treated with chemotherapy (p < 0.05 to p < 0.01). Those patients who had been treated with external radiotherapy and/or brachytherapy had significantly more problems with flatulence and diarrhoea (p < 0.05 to p < 0.001). In conclusion, patients who underwent treatment for gynaecological cancer reported long-term side effects also many years after finishing treatment. The problems where related to treatment modality which should be considered, especially when planning adjuvant treatment.

- Background/Aim: For patients with locally recurrent rectal cancer (LRRC) extensive surgery is often the only curative option and patient selection is crucial. This study aimed to investigate whether magnetic resonance imaging (MRI) characteristics of the primary tumour can predict oncological outcome after surgery for locally recurrent rectal cancer (LRRC). Patients andMethods: All patients undergoing surgery for LRRC with a curative intent at the Karolinska University Hospital 2003-2013 were included. MRI examinations of the primary tumour were re-evaluated.Results: In total, 54 patients were included. A tumour volume decrease of <70% after preoperative radiotherapy or chemoradiotherapy (C)RT for the primary tumour was correlated with a lower proportion of R0 resection of the LRRC (OR=0.07, 95% CI=0.01-0.84). No association between MRI characteristics of the primary tumour and prognosis after LRRC surgery was found.Conclusion: Long-term outcomes after surgery for LRRC were not significantly associated with MRI characteristics of the index tumour. However, factors associated with increased risk of R1 resection of LRRC were identified.

- Aim: Epigenetic modifications, such as DNA methylation, are considered important in the regulation of target genes in cancer development. 5-Hydroxymethylcytosine (5hmC) was recently discovered to be related to the process of malignant transformation. The influence of DNA methylation in oral squamous cell carcinomas (OSCC) is not fully-understood. Therefore, the aim of the present study was to investigate the DNA methylation pattern in OSCC compared to healthy oral epithelium.

- Tamoxifen is the most used adjuvant drug in breast cancer treatment. Its main action is as an anti-oestrogen, but in the endometrium of some patients it acts as an oestrogen. Some investigators have even reported an increased risk of developing endometrial carcinoma. The question of how to follow-up these patients and how to identify patients at risk of developing endometrial premalignant changes was investigated by the noninvasive ultrasound method. The follow-up of 292 patients from before the start of adjuvant treatment with tamoxifen and 94 without tamoxifen treatment was conducted at regular intervals. The changes in endometrial thickness as measured by ultrasound and histopathological changes are reported. A thicker endometrium was found in patients with receptor positive breast cancer even before the treatment with tamoxifen started. Cumulative increasing thickness was found during treatment and this thicker endometrium remained until almost 3 years after the end of treatment. If the endometrium was <3 mm after 3 months of treatment the probability that it would be thin after 5 years was high. An increased risk of developing endometrial carcinoma was found, however due to this regular follow-up the cancer was identified at an early stage.

- Background/aim: The role of single nucleotide polymorphisms (SNPs) in the frequency and intensity of chemotherapy-induced nausea and vomiting (CINV) in women with breast cancer (BC) is unclear. The primary purpose of this study was to compare/evaluate the effect of SNP-guided antiemetic treatment versus standard CINV treatment.Patients and methods: A randomised, factorial, phase II multicentre study design was used. Women planned for neoadjuvant or adjuvant chemotherapy with epirubicin, cyclophosphamide and fluorouracil (FEC /EC, with or without fluorouracil) for BC were randomised to SNP-guided antiemetic treatment (based on the results of SNP analyses) versus standard CINV treatment. Blood samples were taken before the treatment was initiated. Patient-reported data on CINV (during 10 days from onset of cancer treatment) and health-related quality of life (HRQoL), were collected before and after the first cancer treatment.Results: A total of 188 women were included. Overall, nausea was reported by 86% (n=129) of the patients during the ten-day period from the start of cancer treatment. The SNP genotype studied varied. In FAS-CD95, the genotypes AG and GG were overrepresented; in RB1-LPAR6, GG was overrepresented, and in CCL2, both AA and GG were overrepresented. We found no statistically significant difference in CINV between SNP-guided antiemetic treatment versus standard CINV treatment.Conclusion: SNP-guided antiemetic treatment could be as effective as standard treatment. SNP-guided antiemetic treatment of CINV is possibly useful in detecting patients with a higher or lower risk for CINV and thus may help in avoiding over-treatment with toxic components. CINV negatively affects the HRQL.Keywords: Breast cancer; chemotherapy-induced nausea and vomiting; single nucleotide polymorphism.

- Filamin A (FLNA) is the most abundant and widely expressed isoform of filamin in human tissues. It is cleaved by calpain at the hinge 1 and 2 domains, producing a 90-kDa carboxyl-terminal fragment (FLNACT). Recently, it has been shown that FLNACTmediates cell signaling and transports transcription factors into the cell nucleus. However, the significance of cleavage of FLNA by calpain has not been studied in cancer cell growth. Calpeptin is a chemical inhibitor of both calpain 1 and 2 that cleaves FLNA. In this study, we questioned if inhibiting calpain using calpeptin would decrease tumor cell proliferation, migration, invasion, and colony formation.Human melanoma (A7), prostate cancer (PC3), mouse fibrosarcoma (T241) and endothelial (MS1) cells were assayed for proliferation, migration, invasion and colony formation after treatment with calpeptin. Cell lysates were immunoblotted for FLNA and FLNACTResults: Calpeptin treatment of these cells resulted in a decreased production of FLNACTCalpeptin-treated human and mouse tumor cells displayed impaired proliferation, migration, and colony formation.These data suggest that the cleavage of FLNA by calpain is an important cellular event in the regulation of tumor cell growth.

- BACKGROUND/AIM: Cancer is a leading cause of death. Hence, this study aimed at the optimization of niclosamide derivatives for the development of new potential anticancer agents.MATERIALS AND METHODS: Niclosamide derivatives were synthesized and tested against a panel of human cancer cells: MDA and MCF7 breast cancer cells, PC3 and DU-145 prostate cancer cells, Hela cervical cancer cells, and HL-60 acute promyelocytic leukemia cells. They were also tested in nuclear factor-ĸappa B (NFĸB), V-Ki-ras2 Kirsten rat sarcoma viral oncogene (KRAS), and mitochondria transmembrane potential (MTP) assays.RESULTS: N-(3,5-Bis(trifluoromethyl)phenyl)-5-chloro-2-hydroxybenzamide exhibited the most significant cytotoxicity against HL-60 cells, while 5-chloro-N-(2-chlorophenyl)-2-hydroxybenzamide was the most active in the NFĸB assay and 5-chloro-N-(3,5-difluorophenyl)-2-hydroxybenzamide in the MTP assay. 5-chloro-N-(2-chloro-4-(trifluoromethyl) phenyl)-2-hydroxybenzamide and 5-chloro-2-hydroxy-N-(4-hydroxyphenyl)benzamide inhibited both HL-60 cell proliferation and NFĸB.CONCLUSION: In-depth study of the most promising compounds is highly encouraged to further develop into potential anticancer agents those derivatives found to be significantly active.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND:Fitzpatrick's classification is the most common way of assessing skin UV sensitivity. The study aim was to investigate how self-estimated and actual UV sensitivity, as measured by phototest, are associated with attitudes towards sunbathing and the propensity to increase sun protection, as well as the correlation between self-estimated and actual UV sensitivity.PATIENTS AND METHODS:A total of 166 primary healthcare patients filled-out a questionnaire investigating attitudes towards sunbathing and the propensity to increase sun protection. They reported their skin type according to Fitzpatrick, and a UV sensitivity phototest was performed.RESULTS:Self-rated low UV sensitivity (skin type III-VI) was associated with a more positive attitude towards sunbathing and a lower propensity to increase sun protection, compared to high UV sensitivity. The correlation between the two methods was weak.CONCLUSION:The findings might indicate that individuals with a perceived low but in reality high UV sensitivity do not seek adequate sun protection with regard to skin cancer risk. Furthermore, the poor correlation between self-reported and actual UV sensitivity, measured by phototest, makes the clinical use of Fitzpatrick's classification questionable.
