47 clinical anxiety in those with higher mental distress. No effects are reported on patients’ quality of life (QoL). Conclusion Interventions designed to actively involve the GP during curative cancer treatment are scarce and diverse. Even though uptake of interventions is low, results suggest a positive effect of GP involvement on patient satisfaction with care, but not on QoL. Additional effects for vulnerable subgroups were found. More robust evidence for tailored interventions is needed to enable the efficient and effective involvement of the GP during curative cancer treatment. PROSPERO registration number: CRD42018102253 3
