It is recommended that the entire FACT-C (rather than simply the CCS) be used when studying patients with colorectal cancer in order to provide a comprehensive assessment of quality of life. Recommendations are offered concerning the appropriate use of these measures in clinical research and directions for future research with colorectal cancer patients.

Motor, sensory, and integrative activities of the brain are coordinated by a series of midline-bridging neuronal commissures whose development is tightly regulated. Here we report a novel human syndrome in which these commissures are widely disrupted, causing clinical manifestations of horizontal gaze palsy, scoliosis, and intellectual disability. Affected individuals were found to possess biallelic loss-of-function mutations in the axon guidance receptor Deleted in Colorectal Carcinoma (DCC), a gene previously implicated in congenital mirror movements when mutated in the heterozygous state, but whose biallelic loss-of-function human phenotype has not been reported. Structural MRI and diffusion tractography demonstrated broad disorganization of white matter tracts throughout the human CNS including loss of all commissural tracts at multiple levels of the neuraxis. Combined with data from animal models, these findings show that DCC is a master regulator of midline crossing and development of white matter projections throughout the human CNS.

Although limited by small sample size, the study found that parents who left geographically diverse weight management clinics/programs reported similar reasons for attrition. Future efforts should include offering alternative visit times, more treatment options, and financial and transportation assistance and exploring family expectations.
