Prediction of survival prognosis after surgery in patients with symptomatic metastatic spinal cord compression from non-small cell lung cancer

Table 2 The Cox proportional hazards model analysis of preoperative factors for postoperative survival in patients with MSCC from NSCLC

Factors	Simple cox regression		Multiple cox regression
Factors	HR (95 % CI)	P	HR (95 % CI)	P
Preoperative ambulatory status	2.24 (1.30–3.86)	0.004	Excluded^a
ECOG performance status	2.78 (1.54–5.02)	<0.001	2.18 (1.15–4.16)	0.017
Number of involved vertebrae	2.46 (1.39–4.35)	0.002	2.05 (1.11–3.76)	0.021
Visceral metastases	2.29 (1.33–3.94)	0.003	2.00 (1.10–3.62)	0.022
Time developing motor deficits	3.44 (1.90–6.22)	<0.001	2.70 (1.45–5.03)	0.002

MSCC indicates metastatic spinal cord compression; NSCLC, non-small cell lung cancer; ECOG, Eastern Cooperative Oncology Group; HR, hazard ratio; CI, confidence interval
^aSelection = stepwise, preoperative ambulatory status was excluded in the model
