Diagnosis
The treatment of a genetically present lynch syndrome is first of all a preventive measure. Affected persons must therefore have regular check-ups, first of all of the intestine, and later also of the stomach. This allows tumors to be detected early and treated accordingly. The therapy of the developing tumor does not differ from the treatment of other tumors in the respective area. Whether and which method of tumor therapy (surgery, radiation, drug-based chemotherapy) is used depends on the exact type and location of the tumor.
Life expectancy and course of disease
Regular check-ups are crucial for the prognosis of Lynch syndrome. Ultimately, this syndrome involves an increased risk of the affected person developing a malignant tumor. As with all types of cancer, early detection and treatment therefore has a very positive effect on the course of the disease and the chances of recovery.
People with a statistically increased risk of cancer should be regularly checked for the development of a new tumor: This means that relatives of an affected person should undergo a colonoscopy every year from the age of 25 onwards and additionally a gastroscopy from the age of 35 onwards. If these recommendations are followed, the course of the disease is good and life expectancy is not significantly lower than in persons not affected by Lynch syndrome.
