Prospective evaluation of legal difficulties and quality of life in adult survivors of childhood cancer

BACKGROUND

Adult survivors of childhood cancer (ASCC), especially those of the central nervous system (CNS), have increased risks of educational and social difficulties. It is therefore hypothesized they are more likely to encounter legal difficulties (LDs), such as workplace discrimination and disability insurance denials, which may negatively affect their quality of life (QoL).

PROCEDURE

We developed a survey to collect information on patients' legal needs. QoL was assessed using the Functional Assessment of Cancer Therapy (FACT).

RESULTS

We prospectively approached 112 ASCC, 111 (99.1%) of whom completed the survey. The median age of respondents was 7 years at diagnosis and 31 years at survey completion. CNS tumors were the most common malignancy (32.4%). LDs were common overall (40.7%), though more prevalent in patients with CNS versus non-CNS tumors (58.6% vs. 32.3%; P = 0.023). The most prevalent LD was workplace discrimination (58.3%). On multivariate analysis, CNS tumor was the only variable significantly associated with LDs (OR = 4.49, P = 0.041). Individuals with LDs had lower QoL scores compared to those without LDs (79.96 versus 91.83 on the FACT; P =  0.005). On multivariate analysis, individuals with LDs had lower QoL scores (14.95 points lower on the FACT), which is both clinically and statistically significant (P = 0.047).

CONCLUSIONS

Legal difficulties are common in adult survivors of childhood cancer, especially those with brain tumors. Furthermore, individuals with legal difficulties have worse quality of life. Research is needed to develop effective and accessible legal resource programs.

Prospective comparison of the prognostic utility of the Mini Mental State Examination and the Montreal Cognitive Assessment in patients with brain metastases

PURPOSE

The Mini Mental State Examination (MMSE) is the most commonly chosen cognitive screening test (CST) in clinical practice and trials, despite its poor sensitivity, likely because of its prognostic utility. The Montreal Cognitive Assessment (MoCA) is an alternative CST, is more sensitive, and is better correlated with quality of life.

METHODS

Sixty-five patients with brain metastases were prospectively accrued and completed both the MMSE and MoCA. We compared the prognostic utility of both CSTs.

RESULTS

The mean age of patients was 59.0 years; 42.0% had single brain metastases. Median MMSE and MoCA scores were 28 and 22, respectively. Median overall survival (OS) was worse for individuals with below- versus above-average MMSE scores (10.4 versus 36.3 weeks, p = 0.007). Likewise, below- versus above-average MoCA scores were prognostic (6.3 versus 50.0 weeks, p < 0.001). Median OS for MoCA scores <22, 22-26, and >26 were 6.3, 30.9, and 61.7 weeks, respectively (p < 0.001). On multivariable analysis, below-average MMSE scores were no longer prognostic (hazard ratio [HR] = 1.71 [0.90-3.26]), though below-average MoCA scores were (HR = 5.44 [2.70-10.94]). Furthermore, the MoCA demonstrated superior prognostic utility when comparing multivariable models with continuous CST scores.

CONCLUSIONS

Our results indicate that the MoCA is a superior prognostic indicator than the MMSE. Furthermore, given its superior sensitivity and better correlation with quality of life, the MoCA should be preferentially chosen in clinical practice and trials.
