The correlation between the levels of tissue inhibitor of metalloproteinases 1 in plasma and tumour response and survival after preoperattive radiochemotherapy in patients with rectal cancer
Irena Oblak, Vaneja Velenik, Franc Anderluh, Barbara Možina, Janja Ocvirk, 2013, original scientific article

Abstract: Background. The aim of this study was to analyse whether the level of tissue inhibitor of metalloproteinases (TIMP) 1 is associated with the tumour response and survival to preoperative radiochemotherapy in rectal cancer patients. Patients and methods. Ninety-two patients with histologically confirmed non-metastatic rectal cancer of clinical stage I- III were treated with preoperative radiochemotherapy, surgery and postoperative chemotherapy. Plasma TIMP-1 concentrations were measured prior to the start of the treatment with an enzyme-linked immunosorbent assay (ELISA). Results. Median follow-up time was 68 months (range: 3-93 months) while in survivors it was 80 months (range: 68-93 months). The 5-year locoregional control (LRC), disease-free survival (DFS), disease-specific survival (DSS) and overall survival (OS) rates for all patients were 80.2%, 56.4%, 63.7% and 52.2%, respectively. The median TIMP-1 level was 185 ng/mL (range: 22-523 ng/mL) and the mean level (standard deviation) was 192 (87) ng/mL. Serum TIMP-1 levels were found to be significantly increased in patients with preoperative CRP>12 mg/L and in those who died from rectal cancer or had cT4 tumours. No correlation was established for age, gender, carcinoembriogenic antigene (CEA) level, platelets count, histopathological grade, response to preoperative therapy, resectability and disease reappearance. On univariate analysis, various parameters favourably influenced one or more survival endpoints: TIMP-1 <170 ng/mL, CRP <12 mg/L, platelets count <290 10E9/L, CEA <3.4mg/L, age <69 years, male gender, early stage disease (cN0 and/or cT2-3), radical surgery (R0) and response to preoperative radiochemotherapy. In multivariate model, LRC was favourably influenced by N-downstage, DFS by lower CRP and N-downstage, DSS by lower CRP and N-downstage and OS by lower TIMP-1 level, lower CRP and N-downstage. Conclusions. Although we did not find any association between pretreatment serum TIMP-1 levels and primary tumour response to preoperative radiochemotherapy in our cohort of patients with rectal cancer, TIMP-1 levels were recognized as an independent prognostic factor for OS in these patients.

Triple negative breast cancer : prognostic factors and survival
Tanja Ovčariček, Snježana Frković-Grazio, Erika Matos, Barbara Možina, Simona Borštnar, 2011, original scientific article

Abstract: Background. Triple negative breast cancer (TNBC) is defined by a lack of expression of both estrogen (ER) and progesteron(PgR) receptors as well as human epidermal growth factor receptor 2 (HER2). Our retrospective analysis addressed prognostic factors for short- and long-term outcomes of patients (pts) with TNBC pts treated in routine clinical practice. Patient and methods.Our retrospective study included 269 TNBC treated at Institute of Oncology Ljubljana between March 2000 and December 2006. The collected data included patientsć, tumoursć and treatmentsć characteristics. The survival analyses were performed using the Kaplan-Meier method. The Cox proportional hazard model was used in the multivariate analysis. Results. The median age ofour patients was 55.3 yrs (23-88.5) and the median follow-up was 5.9 yrs (0.3-9.6). Six (2%) pts experienced local only, 79 (92%) pts distal recurrenceand 66 (24%) died. The predominant localisation of the first relapsewas in visceral organs (70.4%). The 5-year disease-free survival (DFS) for the entire group was 68.2% and the 5-year overall survival (OS) was 74.5%.We found a pattern of high recurrence rate in the first 3 years following the diagnosis and a clear decline in recurrence rate over the next 3years. In the univariate analysis age, nodal status, size and lymphovascular invasion (LVI) were found to have a significant impact on DFS as well as on OS. In the multivariate analysis only age (HR=1.79; 95%CI=1.14-2.82; p=0.012) and nodal status (HR=2.71; 95%CI=1.64-4.46; p<0.001) retained their independent prognostic value for DFS and for OS only the nodal status (HR=2.96; 95%CI=1.51-5.82; p=0.002).

Laboratorijski vodnik za paciente
Alenka Grošel, Blaž Krhin, Katarina Lenart, Barbara Možina, 2016, dictionary, encyclopaedia, lexicon, manual, atlas, map

Abstract: V pričujoči knjižici smo na enem mestu zbrali vse pomembne informacije v zvezi z odvzemom različnih bioloških vzorcev na Oddelku za laboratorijske dejavnosti Onkološkega inštituta Ljubljana. Upamo, da boste našli uporabne informacije tudi v drugem delu knjižice, kjer so na kratko predstavljene vse laboratorijske preiskave, ki jih na oddelku izvajamo ter njihov pomen za onkološke paciente.
