Table 4 Comparison of recurrence models in patients with disease recurrence between the aBVA and VAB cohorts

From: Different dissecting orders of the pulmonary bronchus and vessels during right upper lobectomy are associated with surgical feasibility and postoperative recovery for lung cancer patients

Variable Total [cases (%)] (n = 301) aBVA cohort [cases (%)] (n = 109) VAB cohort [cases (%)] (n = 192) P value
Total 64 (21.3) 22 (20.2) 42 (21.9) 0.709
Intrathoracic local recurrencea 22 (7.3) 7 (6.4) 15 (7.8) 0.790
Distant recurrence 27 (9.0) 11 (10.1) 16 (8.3) 0.429
Intrathoracic local recurrence and distant recurrence 5 (1.7) 2 (1.8) 3 (1.6) 1.000*
Unknown 10 (3.3) 2 (0.7) 8 (4.2) 0.472*
  1. aBVA RUL with the dissecting order of the posterior ascending arterial branch [a], followed by the right upper bronchus [B] and pulmonary vessels [VA]; VAB RUL with the dissecting order of the right upper pulmonary veins and arteries [VA], followed by the right upper bronchus [B]
  2. * Fisher’s exact test
  3. aOne patient was diagnosed with the progression of multiple primary lesions in each group, which should also be classified as having intrathoracic local recurrence
