Intensive follow-up strategies improve overall survival, increase the detection of asymptomatic recurrences and curative surgery attempted at recurrence, and are associated with a shorter time in detecting recurrences. This more intensive follow-up could not be associated with an improvement in cancer-specific survival nor with an increased detection of total tumor recurrences. Follow-up with serum carcinoembryonic antigen and colonoscopies are related to an increase in overall survival.

QoL was consistently associated with depressive symptoms independently of the measures as well as functional ability and social leisure activities when the QoL questionnaire was rated by proxy. Treating depressive symptoms, increasing social activities and maintaining the functional ability may decrease the deterioration of QoL in institutionalized older adults with dementia.
