    Summary Objective: To determine the usefulness of the SCC, CEA, CYFRA 21.1, and CRP markers for the diagnosis and early monitoring after treatment completion in women diagnosed with cervical squamous cell carcinoma. Material and methods: Serum of 140 patients with diagnosed cervical squamous cell carcinoma was investigated. The women with the advanced stage of cervical carcinoma (FIGO IIIB) were divided into two subgroups: with positive and negative outcomes of the treatment. Levels of SCC, CEA, CYFRA 21.1, and CRP were measured before the treatment and immediately after the completion of radiotherapy. Immunochemical methods were used to measure proteins in both serum and plasma samples. Results: 75% of the markers measured were within the reference range for FIGO stage I. The marker levels rose with the clinical progression of the disease. The median levels of all markers and the CRP levels in both groups were compared before the treatment. Only in case of CEA a considerable variation between these groups was observed. Elevated levels of CRP were observed twice more often in patients with negative outcome of the treatment. After the treatment, a significant decrease in all marker levels was observed in patients with positive outcome when compared to the levels at the moment of the diagnosis. Conclusions: SCC, CEA and CYFRA 21.1 markers show low diagnostic sensitivity in early stages of the disease in women diagnosed with cervical squamous cell carcinoma. The concentration of markers measured before the treatment, particularly CEA, may prove to be of prognostic value for women diagnosed with advanced cervical cancer. Certain markers may prove useful in the assessment of the therapy used. Measuring the CRP before the treatment may aid the prognosis of response to treatment in these patients

    Abstract Introduction: Currently CA 125 is a marker of choice for monitoring ovarian cancer. Nonetheless, scientists are still searching for new markers, which could provide additional information for the evaluation of treatment, especially in patients with normal CA 125 levels, despite the progression of the disease. According to the latest reports, OPN can be a potential new marker. Aim: Estimation of usefulness of OPN determinations in the monitoring of ovarian cancer patients. Material and Methods: The study included 54 ovarian cancer patients, undergoing chemotherapy. Markers were measured before, during and after treatment. The dynamics of the change of OPN levels was shown on line graphs, using Microsoft Excel programme. Statistical analysis was performed by Kaplan-Meier method and log-rank test. Results: 44% of patients from the study group were found to have low CA 125 levels. In these cases only the increase of OPN concentration indicated recurrence of the disease. In 43% of patients the high initial CA 125 and OPN levels decreased during chemotherapy and complete regression was stated in these patients. Nevertheless, in 13/17 patients a repeated increase of OPN concentration signalling the recurrence, earlier than CA 125 and clinical recurrence manifestation, was observed. In 13% of patients high initial levels of markers did not decrease during chemotherapy, which correlated with the progression of the disease. Our study showed that only the CA 125 levels had a significant influence (p=0.00063) on the disease-free survival time. Conclusions: Our data suggest a potential usefulness of the OPN determinations in estimating ovarian cancer recurrence. Nonetheless, there was no correlation between the initial OPN concentration and the disease-free survival time

    Summary Objective: an attempt to determine the value of the simultaneous quantization of osteopontin (OPN), insulingrowth factor II (IGF II), leptin, prolactin and CA 125 for early detection of ovarian cancer Materials and methods: Prospective study of 69 women including: - 15 females with ovarian cancer - 33 females with benign ovarian neoplasm - 21 disease-free females The levels of IGF II, prolactin, leptin and CA 125 were determined in serum, while the level of OPN was checked in plasma. Results: The concentrations of IGF II, leptin and prolactin do not let us distinguish among disease-free females, females with ovarian cancer and those with benign ovarian neoplasms on the basis of biochemical markers. The comparison of OPN and CA 125 levels showed significant differences in the concentrations of the biomarkers between disease-free females and females with ovarian cancer, as well as between females with benign ovarian neoplasms and females with ovarian cancer. The ROC curves for two groups: disease-free females and females with ovarian cancer, proved the diagnostic value of OPN and CA 125. Conclusions: The simultaneous quantization of OPN, IGF II leptin and prolactin has not been proved useful for the early detection of ovarian cancer. Statistically significant increase of OPN & CA 125 levels was noted in case of women with ovarian cancer diagnosed through microscopic examination. The analysis of ROC curves showed comparable diagnostic usefulness of both markers. Quantization of OPN may have an additional value for treatment monitoring of women diagnosed with ovarian cancer but with concentration of CA 125 within the reference value

    Common Variants in Osteopontin and <i>CD44</i> Genes as Predictors of Treatment Outcome in Radiotherapy and Chemoradiotherapy for Non-Small Cell Lung Cancer

    Osteopontin (OPN)-CD44 signaling plays an important role in promoting tumor progression and metastasis. In cancer, OPN and CD44 overexpression is a marker of aggressive disease and poor prognosis, and correlates with therapy resistance. In this study, we aimed to evaluate the association of single nucleotide polymorphisms (SNPs) in the OPN and CD44 genes with clinical outcomes in 307 non-small cell lung cancer (NSCLC) patients treated with radiotherapy or chemoradiotherapy. The potential impact of the variants on plasma OPN levels was also investigated. Multivariate analysis showed that OPN rs11730582 CC carriers had a significantly increased risk of death (p = 0.029), while the CD44 rs187116 A allele correlated with a reduced risk of locoregional recurrence (p = 0.016) in the curative treatment subset. The rs11730582/rs187116 combination was associated with an elevated risk of metastasis in these patients (p = 0.016). Furthermore, the OPN rs1126772 G variant alone (p = 0.018) and in combination with rs11730582 CC (p = 7 × 10−5) was associated with poor overall survival (OS) in the squamous cell carcinoma subgroup. The rs11730582 CC, rs187116 GG, and rs1126772 G, as well as their respective combinations, were independent risk factors for unfavorable treatment outcomes. The impact of rs11730582-rs1126772 haplotypes on OS was also observed. These data suggest that OPN and CD44 germline variants may predict treatment effects in NSCLC

    We propose a one-day transdisciplinary creative workshop in the broad area of HCI focused on multiple opportunities of incorporating participatory design into research and industry practice. This workshop will become a venue to share experiences and novel ideas in this area. At the same time, we will brainstorm and explore frontiers of HCI related to engaging end users in design and development practices of established and emerging ICT solutions often overlooked in terms of co-design. We welcome a wide scope of contributions in HCI which explore sustainable opportunities for participatory design and development practices in the context of interconnected business, social, economic and environmental issues. The contributions ought to explore challenges and opportunities related to co-design at the frontiers of HCI - participatory design of newest and complex technologies, not easily explainable or intuitive, novel collaborative (remote or distributed) approaches to empowering users to prepare them to contribute as well as to engaging them directly in co-design.Comment: 6 pages, 1 figure, workshop held at Interact 202
