Almost half of patients (361\/743, 45%) did not visit their PCP during treatment. Visit rate during treatment was 0.64 per person per year (PPPY) versus 1.4 PPPY among controls (adjusted rate ratio [aRR] 0.47, 95th confidence interval [95CI]: 0.40\u20130.54; <jats:italic>p<\/jats:italic>\u00a0&lt;\u00a0.0001). No disease\u2010 or PCP\u2010related factors were associated with visit rates. Total 711 patients completed frontline therapy; 287 (40.4%) did not have a PCP visit after treatment.
