27. 10. 2015 Cancer in the older population of the Czech Republic
Population ageing has become a challenge to cancer care in developed countries. Particularities of the older population must be taken into account when considering cancer treatment. However, there is a lack of consensus on guidelines for this population due to the underrepresentation of older patients in clinical trials.
15. 1. 2014 Personalised invitations of Czech citizens to cancer screening programmes
In January 2014, a project of personalised invitations for cancer screening programmes was launched in the Czech Republic. In particular, citizens are invited to participate in colorectal cancer screening (men and women), as well as breast cancer screening and cervical cancer screening (women). Personalised invitations are aimed at citizens who have not participated in cancer screening programmes in the long term, and therefore are at a higher risk of developing cancer. The project is expected to increase participation rates in Czech cancer screening programmes.

Colon cancer growth reduced by exercise
Exercise may play a role in reducing the growth of colon cancer cells according to new research published in The Journal of Physiology [1]. The study found that after a short session of high intensity interval training (HIIT), growth of colon cancer cells was reduced, and this also increased indicators of inflammation.
For a long time, the focus on exercise has been on the positive changes in the body that occur following a longer period of training. However, these findings suggest that the effects following a single session of HIIT, an exercise regime involving short, high energy bursts are also important.
The changes following HIIT suggest that repeated exposure to the acute effects of exercise may contribute to the fight against the cancer. These results reinforce the importance of doing regular exercise and maintaining a physically active lifestyle.
The study conducted by The University of Queensland in conjunction with the University of Waterloo, Ontario, involved colorectal cancer survivors completing either a single session of HIIT or 12 sessions over 4 weeks. Their blood samples were collected either immediately after the single session of exercise or at rest after 4 weeks of training, and were then analysed to study the growth of colon cancer cells.
Importantly the method used to model the colon cancer cells in the laboratory is very different to how they grow in the human body, requiring future research to translate these findings into human tumours.
James Devin, lead author on the research said:
“We have shown that exercise may play a role in inhibiting the growth of colon cancer cells. After an acute bout of HIIT there were specific increases in inflammation immediately after exercise, which are hypothesised to be involved in reducing the number of cancer cells.”
“This suggests that a physically active lifestyle may be important in tackling human colorectal tumours. We would now like to look at how these changes in growth occur and understand the mechanisms by which biomarkers in the blood can impact cell growth.”
