RESUMO
BACKGROUND: Platelets support tumour progression. However, their prognostic significance and relation to circulating tumour cells (CTCs) in operable breast cancer (BrCa) are still scarcely known and, thus, merit further investigation. METHODS: Preoperative platelet counts (PCs) were compared with clinical data, CTCs, 65 serum cytokines and 770 immune-related transcripts obtained using the NanoString technology. RESULTS: High normal PC (hPC; defined by the 75th centile cut-off) correlated with an increased number of lymph node metastases and mesenchymal CTCs in the 70 operable BrCa patients. Patients with hPC and CTC presence revealed the shortest overall survival compared to those with no CTC/any PC or even CTC/normal PC. Adverse prognostic impact of hPC was observed only in the luminal subtype, when 247 BrCa patients were analysed. hPC correlated with high content of intratumoural stroma, specifically its phenotype related to CD8+ T and resting mast cells, and an increased concentration of cytokines related to platelet activation or even production in bone marrow (i.e. APRIL, ENA78/CXCL5, HGF, IL16, IL17a, MDC/CCL22, MCP3, MMP1 and SCF). CONCLUSIONS: Preoperative platelets evaluated alone and in combination with CTCs have prognostic potential in non-metastatic BrCa and define patients at the highest risk of disease progression, putatively benefiting from anti-platelet therapy.

AIM: The aim of the study was to analyze long term results and prognostic factors in women with preinvasive breast cancer (DCIS - ductal carcinoma in situ) who underwent breast conserving surgery with subsequent radiotherapy. MATERIALS AND METHODS: A total number of 106 patients was analyzed aged 29-78 years; mean age was 54,3 years and median 55 years. In 78 (73,5%) patients the tumor was diagnosed incidentally on mammography or ultrasound scan, 28 (26,5%) had palpable lesion. 57 patients had the tumor in the left breast and 49 in the right one. Most often the tumor was localized in external quadrants, namely in 56 (52,8%) patients. All patients had breast conserving surgery and then adjuvant radiotherapy of the breast in typical doses. For evaluation of survival we used the Kaplan-Meier test and for evaluation of cumulated loco-regional recurrence we have applied the method of competing risks. RESULTS: At present 101 patients are still alive, 85 have no relapse. 15 patients had local recurrence and 8 had another cancer. Five patients died during follow-up period. Overall 15-years survival in analyzed group was 88% and disease free survival was 74%. Of all prognostic factors only the value of Van Nuys index was relevant. Patients who had the index value less than 7 had significantly worse prognosis than patients with value 7 or more (p=0,043). CONCLUSIONS: At present 101 patients are still alive, 85 have no relapse. 15 patients had local recurrence and 8 had another cancer. Five patients died during follow-up period. Overall 15-years survival in analyzed group was 88% and disease free survival was 74%. Of all prognostic factors only the value of Van Nuys index was relevant. Patients who had the index value less than 7 had significantly worse prognosis than patients with value 7 or more (p=0,043).

An attempt was made to compare the usefulness of determining markers carcinoembryonic antigen (CEA) and tumor-associated trypsin inhibitor (TATI) in endometrial cancer patients in whom recurrence or distant metastasis was diagnosed in observation after treatment. The study included 316 patients aged 32-81, average age of 61 years, SD = 8.72, with diagnosed endometrial cancer, treated between 1994 and 1995 at the Oncology Center in Warsaw and then under observation from 4 months to 17 years after completion of treatment. The levels of the markers TATI and CEA were assessed from the first five serum samples taken during postoperative radiotherapy and in the initial period of observation after completed treatment. Receiver operating characteristic (ROC) curves were generated, determining the sensitivity and specificity of both CEA and TATI in patients who experienced treatment failure, i.e., recurrence and distant metastasis. Assessing the sensitivity of the marker CEA, it was found that if in the third sample, i.e., during radiation therapy, the marker level increased by more than 20 % compared with the first sample, then recurrence of cancer occurred during the observation period in 75.9 % of patients and metastatic occurred in 69.7 % of patients. In the evaluation of the marker TATI, it was found that if the level of TATI between the first and the third sample increases by 10.6 % from the initial level, then in 84.4 % (sensitivity) of cases, this means the occurrence of cancer recurrence and in 75.7 % (sensitivity) of cases, the occurrence of metastasis. The specificity of both markers is low and not useful diagnostically.

OBJECTIVES: This article presents an analysis of the narratives of people with schizophrenia from the perspective of descriptions of activities. The goal is to look for changes in activity models under the influence of a psychotic crisis experience. METHODS: Three fragments of auto-narratives concerning periods: prior to illness, during illness and during remission periods, were compared. These were created after psychotic crisis. The narratives of 26 people with schizophrenia about their lives and self-perception during the aforementioned periods made up the research material. Linguistics textual analysis was conducted, distinguishing the determinants of six selected models of activity relating to sense of agency and intentionality of action. Frequency analysis and multivariable methods were applied to compare the relative frequency of their occurrence in narratives. RESULTS: Descriptions of activities during the illness are more strongly saturated with models of an extrinsic control site, impersonal control over action, avoidance, individual actions, states in comparison to the remission period, and in particular, descriptions of activity prior to the illness. CONCLUSIONS: The results of analysis of schizophrenia patients' narratives indicate a decreased sense of agency related to experiencing states of disorder (subjectively defined). This motivational deficit also concerns remission periods after the active phase of the illness, though to a lesser extent. Analysis of motivational models reveals differences of descriptions of own activity, indicating alterations in auto-narration and narrative identity under the influence of a psychotic crisis in a retrospective approach. These changes pertain to deep layers hidden in the relationship between the form of the narrative and its content. They indicate other images of oneself (self-positions or self-narrative voices) as a healthy, sick and in remission person - especially in terms of the perception of their own agency.

AIM: The aim of the study was to look for prognostic factors of metastasis or recurrence in patients with endometrial cancer. METHODS: Tumor-associated trypsin inhibitor (TATI) concentrations were measured in serum of 317 patients with endometrial cancer. The assay was done 7 times in each patient, from the moment of diagnosis until the start of follow-up after the completion of treatment. Observation of patients after treatment lasted from 0 to 16 years. RESULTS: The TATI levels in patients with adverse prognostic factors accumulated in the first 3 assays and then decreased to zero. Mean TATI concentrations were significantly higher in patients with clinically advanced disease (stage IIIB) than patients at stage I (Kruskal-Wallis p = 0.0446). An increase in the concentration by more than 10.6% in the first 3 assays was significantly correlated with disease relapse (Mann-Whitney Z = -6.06653, p = 0.00000) and local or distant recurrence (Mann-Whitney Z = -4.97475, p = 0.000001). A significant increase in the TATI level in the first 3 tests also occurred in patients who died during the study period (Kruskal Wallis p<0.001). In our series of patients with endometrial cancer, TATI proved to be a sensitive indicator of disease recurrence and distant metastasis, with a sensitivity of 84.4% and 75.7%, respectively. CONCLUSIONS: TATI seems to behave as a prognostic factor in certain subgroups of patients with endometrial cancer.

Ovarian cancer makes up 25-30% of all cases of cancers of the female genital tract. It has the highest mortality rate of any condition in oncological gynaecology. Early diagnosis is associated with a favourable 5-year survival prognosis. Many solid tumours have been detected with concomitant thrombocytosis. The tumour cell-induced platelet aggregation is a result of a direct integration of tumour cells with blood platelets. The aim of the present paper is an evaluation of platelet count as a prognostic parameter for ovarian cancer. Between 2000 - 2005, 349 patients with ovarian tumour (aged 12 - 88-years-old) underwent primary surgical treatment at a clinic. Ninety-seven patients with ovarian carcinomas underwent chemotherapy in the Oncology Centre. The control group comprised 252 women diagnosed with a histopathological lesion of mild intensity, whereas the cancer group constituted 97 women with a histopathologically-diagnosed malignant neoplasm. Thrombocytopaenia was assumed with a platelet count below 150G/L and thrombocythaemia at 350G/L and higher. Thrombocytosis often coincides with ascites and the cytoreduction decreases platelet count. There is a positive correlation between platelet count and tumour grading. Thrombocytosis was more frequently found in high grade tumours. There is also a positive correlation between platelet count and tumour stage according the International Federation of Gynaecology and Obstetrics (FIGO). Thrombocytosis was more frequently found in stage III and IV cancers. Patients with co-occurring thrombocytosis were found to have shorter survival periods and shorter time free from disease. This seems to give grounds for measuring platelet count before the primary surgical intervention, and suggests that the platelet count should be included in the panel of prognostic factors for patients with ovarian tumours.
