Urine and bladder washing cytology for detection of urothelial carcinoma : standard test with new possibilities
Margareta Strojan Fležar, 2010, review article

Abstract: Background. Light microscopic evaluation of cell morphology in preparations from urine or bladder washing containing exfoliated cells is a standard and primary method for the detection of bladder cancer and also malignancy from other parts of the urinary tract. The cytopathologic examination is a valuablemethod to detect an early recurrence of malignancy or new primary carcinoma during the follow-up of patients after the treatment of bladder cancer. Conclusions. Characteristic cellular and nuclear signs of malignancy indicate invasive or in situ urothelial carcinoma or high-grade papillary urothelial carcinoma. However, low sensitivity of the method reflects the unreliable cytopathologic diagnosis of low-grade urothelial neoplasms as cellular and nuclear signs of malignancy in these neoplasms are poorly manifested. Many different markers were developed to improve the diagnosis of bladder carcinoma on urinary samples. UroVysionT test is among the newest and most promising tests. By the method of in situ hybridization one can detect specific cytogenetic changes of urothelial carcinoma.

Intrahepatic cauda/inferior vena cava interruption with azygos/hemiazygos continuation. Vascular anomaly in swine
Miran Jeromel, Dušan Pavčnik, 2010, original scientific article

Abstract: Background. Electrochemotherapy is a local treatment combining application of electric pulses and chemotherapy. Two chemotherapeutic drugs, bleomycin and cisplatin, have proved to be effective in electrochemotherapy. The effectiveness of electrochemotherapy was demonstrated in the treatment of various cutaneous and subcutaneous tumours in cancer patients. Only a few preclinical studies were performed in colorectal carcinoma, mostly using bleomycin. Our aim was to evaluate the sensitivity of the murine colorectal carcinoma cell line CMT-93 to electrochemotherapy with bleomycin and cisplatinfor potential use in preclinical and clinical studies. Methods. CMT-93 cells were exposed to either the chemotherapeutic drug alone or electrochemotherapy. A clonogenic assay was used to determine cell survival after treatment. Apoptosis was measured by caspase-3/7 activity, necrosis by changes in cell morphology and cell viability by the MTS assay 16 hours after electrochemotherapy. Results. Cells treated with electrochemotherapy were 500-fold more sensitive to bleomycin and 2.8-fold more sensitive to cisplatin compared to cells treated with the drugs alone. At the highest concentrations,a significant reduction in cell viability, increase in caspase-3/7 activity and necrotic cells were observed after electrochemotherapy. Conclusions. Exposure of cells to electric pulses enhanced cytotoxicity of both bleomycin and cisplatin. Reduced cell viability was due to apoptotic and necrotic cell death. Furthermore, electrochemotherapywith bleomycin was more cytotoxic than electrochemotherapy with cisplatin in this colorectal carcinoma cell line.

Evaluation of clinical interventions made by pharmacists in chemotherapy preparation
Lea Knez, Raisa Laaksonen, Catherine Duggan, 2010, original scientific article

Abstract: Background. Cancer drugs are high risk drugs and medication errors in their prescribing, preparation and administration have serious consequences, including death. The importance of a multidisciplinary approach and the benefits of pharmacistsć contribution to cancer treatment to minimise risk have been established. However, the impact of services provided by pharmaciststo cancer patient care is poorly studied. This study explored the clinical interventions made by pharmacists in dispensing of chemotherapy doses, and evaluated pharmacistsć contribution to patient care. Methods. Pharmacists at the Chemotherapy Preparation Unit at a tertiary cancer centre in London were shadowed by two research pharmacists during the clinical screening of chemotherapy prescriptions and release of prepared drugs. An expert panel of pharmacy staff rated the clinical significance of the recordedinterventions. Results. Twenty-one pharmacistsć interventions were recorded during the screening or releasing of 130 prescriptions or drugs. ĆDrug and therapyĆ (38%), ĆclericalĆ (22%) and Ćdose, frequency and durationĆ (19%) related problems most often required an intervention, identifying areas in chemotherapy prescribing that need improvement. The proposed recommendations were implemented in 86% of the cases. Many recorded interventions (48%) were ranked to have had a Ćvery significantĆ influence on patient care. Conclusion. Clinical interventions made by pharmacists had a significant impact on patient care. The integration of pharmacistsć technical and clinical roles into dispensing of chemotherapy doses is required for providing high-quality cancer services.

Antigen expression on recurrent meningioma cells
Andrej Vranič, 2010, original scientific article

Abstract: Introduction. Meningiomas are intracranial brain tumours that frequently recur. Recurrence rates up to 20% in 20 years for benign meningiomas, up to 80% for atypical meningiomas and up to 100% for malignant meningiomas, have been reported. The most important prognostic factors for meningioma recurrenceare meningioma grade, meningioma invasiveness and radicality of neurosurgical resection. The aim of our study was to evaluate the differences in antigenic expression on the surface of meningioma cells between recurrent and non-recurrent meningiomas. Methods. 19 recurrent meningiomas and 35 non-recurrent meningiomas were compared regarding the expression of MIB-1 antigen, progesterone receptors, cathepsin B and cathepsin L, using immunohistochemistry. Results. MIB-1 antigen expression was higher in the recurrent meningioma group (p=0.001). No difference in progesterone receptor status between recurrent and non-recurrent meningiomas was confirmed. Immunohistochemical intensity scores for cathepsin B (p= 0.007) and cathepsin L (p<0.001) were both higher in the recurrent than in the non-recurrent meningioma group. Conslusions. MIB-1 antigen expression is higher in recurrentcompared to non-recurrent meningiomas. There is no difference in expression of progesterone receptors between recurrent and non-recurrent meningiomas. Cathepsins B and L are expressed more in recurrent meningiomas.

Genetic markers in oligodendroglial tumours
Tomaž Velnar, Uroš Smrdel, Mara Popović, Gorazd Bunc, 2010, review article

Abstract: Background. Oliogodendrogliomas are brain tumours composed of the cells resembling oligodendrocytes. They represent the third most common glial tumour, comprising 2.5% of all primary brain tumours and 5-20% of all gliomas. Conclusions. Oligodendroglial tumours with 1p and 19q loss demonstrate a better overall prognosis due to more indolent clinical behaviour and higher sensitivity to treatment. Additionally, 1p and 19q loss is a marker of clinical utility, helping to assess tumour sensitivity to chemotherapy and harbouring the potential for improving the diagnosis and survival of oligodendroglioma patients as well as future clinical practice.
