The analysis of effectiveness and undesirable effects of the radical chemoradiotherapy of anal cancer
Vácha, Ondřej ; Vítek, Pavel (advisor) ; Konopásek, Bohuslav (referee)
The subject of presented bachelor thesis is an analysis of efficacy and side effects in chemoradiotherapy of anal canal cancer. High anticancer activity besides severe adverse effects are specific for anal canal cancer. Adverse effect may finally negatively influence even overall survival. The data of 110 patients treated within the last 20 years at the Institute of Radiation Oncology, University Hospital Na Bulovce, Prague were analyzed to determine an impact of radiation delivery technique, chemotherapy and other variables on treatment results. Common chemoradiation regimen of mitomycin + 5-FU and radiation up to 60 Gy was employed. The single-institution data confirm high efficacy of standard treatment in terms of survival and relapse rate. There is a substantial rate of acute and delayed toxicity. Therefore there is a significant reduction of chemotherapy in elderly patients. However the survival and time to relapse data do not significantly differ in elderly patients. The age at diagnosis as a continuous variable does not significantly influence either survival or time to relapse. More advanced radiation delivery technique IMRT brings significantly less side effects compared to classic 2D and 3D conformal radiation therapy. Conclusions: High toxicity of standard chemoradiation for anal canal...

Toxicity of chemoradiotherapy in patients older 60 years with rectum cancer
BABOROVÁ, Monika
The Czech Republic belongs to countries with high incidence of rectal cancer . Annually, 2600 cases of rectal tumors are detected. In the Czech Republic the rectal cancer is the second most frequent tumor disease in men and women. Mortality is also high, it is the cause of more than 4000 deaths per year. The treatment of particular malignant tumors combines radiotherapy and chemotherapy. The reason for combining radiotherapy with chemotherapy is the enhanced treating effect on the tumor tissue while adverse effects on healthy tissues are still bearable. The administration of appropriate cytostatics may potentiate the effect of the combined treatment. The method of concomitant chemoradiotherapy leads to better therapeutic effects in patients. However, the combined treatment is more toxic both for the tumor and the patient´s healthy tissues in areas affected by both the curative methods.
