11. Cathepsin X in serum from patients with colorectal cancer: relation to prognosisTjaša Vižin, Ib Jarle Christensen, Hans Jørgen Nielsen, Janko Kos, 2012, original scientific article Abstract: Background. Up-regulation of lysosomal cysteine protease cathepsin X (Cat X) is associated with disorders of the immune system and neurodegenerative diseases, while its role in the development and progression of cancer is less understood. Enhanced secretion of pro-Cat X was observed in malignant processes, and therefore, the level of total serum Cat X rather than the active enzyme may better reflect the tumour status. Patients and methods. Seventy-seven patients with colorectal cancer (CRC) were included in a retrospective study. Blood samples were collected prior to therapy. Using ELISA, the values of total Cat X were measured in serum. Groups of healthy persons (n=77), patients with adenomas (n=77) and patients with non-neoplastic findings (n=77) were included. Results. Significant differences between the group of colorectal patients and the groups of healthy persons, adenoma patients and patients with non-malignant findings could not be shown (p=0.89). Within the group of CRC, higher levels of total Cat X significantly correlated to shorter overall survival (HR=2.08, 95% CI:1.07-4.05, p=0.028). Conclusions. Total serum Cat X could be a useful prognostic indicator for determining survival of patients with CRC. Increased serum levels of total CatX may reflect more aggressive tumour cell phenotypes and suggest the involvement of Cat X in processes involved in later stages of tumour progression.

12. Coping strategies of patients with advanced lung or colorectal cancer in six European countries : insights from the ACTION studyLea J. Jabbarian, Ida Joanna Korfage, Branka Červ, Johannes JM van Delden, Luc Deliens, Guido Miccinesi, Sheila Payne, Anna Thit Johnsen, Mariette Verkissen, Andrew Wilcock, Agnes van der Heide, Judith Anna Catharina Rietjens, 2020, review article Abstract: Objective: Even when medical treatments are limited, supporting patients' coping strategies could improve their quality of life. Greater understanding of patients' coping strategies, and influencing factors, can aid developing such support. We examined the prevalence of coping strategies and associated variables. Methods: We used sociodemographic and baseline data from the ACTION trial, including measures of Denial, Acceptance and Problem-focused coping (COPE; Brief COPE inventory), of patients with advanced cancer from six European countries. Clinicians provided clinical information. Linear mixed models with clustering at hospital level were used. Results: Data from 675 patients with stage III/ IV lung (342, 51%) or stage IV colorectal (333, 49%) cancer were used; mean age 66 (10 SD) years. Overall, patients scored low on Denial and high on Acceptance and Problem-focused coping. Older age was associated with higher scores on Denial than younger age ([beta] = 0.05; CI[0.023; 0.074]), and patients from Italy ([beta] = 1.57 CI[0.760; 2.388]) and Denmark ([beta] = 1.82 CI[0.881; 2.750]) scored higher on Denial than patients in other countries. Conclusions: Patients with advanced cancer predominantly used Acceptance and Problem-focused coping, and Denial to a lesser extent. Since the studied coping strategies of patients with advanced cancer vary between subpopulations, we recommend taking these factors into account when developing tailored interventions to support patients' coping strategies.
