Zhao Cheng at the Surgical Care Science research group, Department of Molecular Medicine and Surgery, will defend her thesis "Outcomes of surgery for oesophageal cancer with focus on fatigue" on November 29, 2022.
Main Supervisor is Pernilla Lagergren.

What's the main focus of your thesis?

The main focus of my thesis is to provide knowledge that can improve outcomes and survivorship in patients who underwent curatively intended surgical treatment for oesophageal cancer.

Which are the most important results?

In the studies, we found that preoperative comorbidities were associated with increased risk of reoperation or death after oesophagectomy, and patients after oesophageal cancer surgery might have distinctly different cancer-related fatigue trajectories. Factors that might be associated with higher levels of cancer-related fatigue trajectories included more comorbidities, advanced tumour stage, postoperative complications, anxiety, depression, and pain.

How can this new knowledge contribute to the improvement of people's health?

This thesis provides evidences regarding the risk factors of poor postoperative outcomes. The identified longitudinal trajectories offer a clearer picture of the development of cancer-related fatigue during the survivorship of oesophageal cancer patients.

What are your future ambitions?

I very much look forward to being an experienced epidemiologist, using my knowledge to help provide health-related evidence and improve people’s health.
