Background:
The burden of having neurologic symptoms (NS) in cancer patients has scantly been studied; therefore, we performed a study whose purpose was to measure the impact of having clinically active (NS) on the quality of life (QoL) of non-primary CNS cancer patients.
Methods:
Patients with systemic cancer (non-primary CNS cancer) sent for neurological evaluation at a single cancer center (INCAN) were prospectively invited to respond the EORTC-QLQ-C30 and BN20 questionnaires. Associations of the questionnairés items were blindly measured for the following groups: NS+ or not (NS-) and having active cancer (AC+) or not (AC-).
Results:
Of 205 patients aged 55.4 ± 15.4 years, 122 (60%) had NS+ and 107 (52%) AC +. The NS+ group (compared with the NS-) showed a significant worse perception in the following scales/items of the EORTC QLQ-C30: physical functioning (median 86 vs. 92, P = 0.012), role functioning (66 vs. 100, P < 0.001), emotional functioning (75 vs. 83, P = 0.005), cognitive functioning (66 vs. 83, P < 0.001), fatigue (33 vs. 22, P < 0.001), nausea and vomiting (P = 0.021), pain (33 vs. 16, P < 0.001), insomnia (33 vs. 0, P = 0.011), appetite loss (P = 0.021), and global health (66 vs. 75, P = 0.001).
Conclusion:
In patients with systemic (non-CNS) cancer, the QoL is significantly worse for patients with active neurologic symptoms.

However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
