Survival of all patients was calculated and prognostic factors for survival were assessed in univariate and multivariate analysis. In 31 patients QoL was assessed in median 3 years (range 2-8 years) after treatment. QoL was compared to published normative data and the influence of age, tumour stage, treatment and observed acute toxicities was analyzed.</p></div><div id="j_raon-2018-0029_s_003_w2aab2b8b8b1b7b1aab1c16b3Aa" class="section"><h3 class="abstractTitle text-title my-1" id="d6e11">Results</h3><p>Thirty-six patients (43.4%) died, 18 (21.7%) had a local recurrence and 24 (28.9%) had a distant progression. Parametrial boost (p = 0.027) and ChT (p = 0.041) were independent prognostic factors for overall survival in multivariate analysis. Specifically, a parametrial equivalent doses in 2-Gy fractions (EQD2) > 50 Gy was associated with an improved overall survival (OS) (p = 0.020), but an EQD2 > 53 Gy did not further improve OS (p = 0.194). Tumour size was the only independent prognostic factor for local control (p = 0.034). Lymph node status (p = 0.038) and distant metastases other than in paraaortic lymph nodes (p = 0.002) were independent prognostic factors for distant progressionfree survival. QoL was generally inferior to the reference population. Age only correlated with menopausal symptoms (p = 0.003). The degree of acute gastrointestinal (p = 0.038) and genitourinary (p = 0.041) toxicities correlated with the extent of chronic symptom experience. Sexual/vaginal functioning was reduced in patients with larger tumours (p = 0.012). Parametrial EQD2 > 53 Gy correlated with reduced sexual/vaginal functioning (p = 0.009) and increased sexual worry (p = 0.009). Whether parametrial dose escalation was achieved by sequential boost or SIB, did not affect survival or QoL.</p></div><div id="j_raon-2018-0029_s_004_w2aab2b8b8b1b7b1aab1c16b4Aa" class="section"><h3 class="abstractTitle text-title my-1" id="d6e14">Conclusions</h3><p>Primary RChT is an effective treatment, but long-term QoL is reduced. The degree of acute side effects of RChT correlates with the extent of chronic symptoms. Patients benefit from parametrial SIB or sequential boost, but an EQD2 > 53 Gy does not further improve survival and negatively affects QoL.</p></div></section>
