Identification of early symptoms and changes in QoL and functioning among men with primary localized prostate cancer who later develop metastases : a matched, prospective study

• Objective To identify early symptoms and changes in QoL among men with primary localized prostate cancer (PC) who later develop metastases. Methods From an ongoing prospective study of 3.885 men with localized PC, primarily treated with radiotherapy (RT), a subsample of men developing metastatic PC (mPC) following the first year after the start of RT and that had died during the follow-up (mPC group, n = 107) were matched against men who did not develop metastases (non-mPC group, n = 214). Data were collected using the EORTC QLQ-C30 and PCSS instruments. Non-parametric tests were performed for comparisons at baseline, end of RT, 3 months, and 1, 2, 3, and 5 years after RT. Results The final sample consists of 317 men (mPC n = 106; non-mPC n = 211) who had completed at least one questionnaire. Initially, symptom levels were generally low and QoL and functioning high in both groups. An increasing difference between the groups was found, where the mPC group gradually deteriorated from the 2-year follow-up. Significant differences were found for several outcomes at 3 and 5 years. In a sensitivity analysis, where metastatic patients were removed from the time-point of verified metastases, most differences did not remain significant. Significant deterioration over time was seen within both groups for some outcomes. Significance of results The results indicate that unmet supportive needs occur over time among these men. Worsening QoL or functioning and symptoms may be difficult to recognize when the development is gradual over several years, and with various access to systematic follow-up in late phases. This highlights the need for continuous monitoring of PC patients to detect needs for supportive interventions early and throughout the disease course, also among those with non-metastatic disease who have undergone curatively intended treatment.
