1. Qol (EORTC QLQC30) absolute values and change over time (Time Frame - day 0, end of week 6, 12, 19, 32, 58, 84, 110, 162, 214, 266): Quality of life measured by EORTC questionaire QLQC30 in absolute values at different time points and change over time
2. Qol (EORTC QLQCR29) absolute values and change over time (Time Frame - day 0, end of week 6, 12, 19, 32, 58, 84, 110, 162, 214, 266): Quality of life measured by EORTC questionaire QLQCR29 in absolute values at different time points and change over time
Secondary outcome:
1. local control (Time Frame - end of week 6, 12, 19, 32, 58, 84, 110, 162, 214, 266): absence of disease progression inside the target volume of radiation therapy
2. distant control (Time Frame - end of week 6, 12, 19, 32, 58, 84, 110, 162, 214, 266): absence of disease progression outside the target volume of radiation therapy
3. freedom from treatment failure (Time Frame - end of week 6, 12, 19, 32, 58, 84, 110, 162, 214, 266): absence of disease progression inside or outside the target volume of radiation therapy
4. overall survival (Time Frame - end of week 6, 12, 19, 32, 58, 84, 110, 162, 214, 266): absence of death from any cause
5. acute toxicity (Time Frame - day 0, end of week 6, 12, 19): acute toxicity caused by chemoradiation according to CTCAE 4.03
6. late toxicity (Time Frame - end of week 32, 58, 84, 110, 162, 214, 266): late toxicity caused by chemoradiation according to CTCAE 4.03
