Primary tumor location and metastatic site in bone-metastatic LADC patients. (A) Peripherally located primary tumors are associated with femoral (OR 3.486, 95%CI 1.09–14.71, p = 0.022) and rib (OR 2.338, 95%CI 1.16–4.86, p = 0.012) metastases, whereas central LADCs give rise to humeral metastases (OR 0.262, 95%CI 0.06–0.83, p = 0.018). (B) Left-sided tumors are more frequently associated with skull metastases compared to right-sided primary LADCs (OR 4.836, 95%CI 1.19–28.19, p = 0.018). (C) No significant differences were found in metastasis pattern with regards to upper/middle lobe vs. lower lobe classification.
