Intramedullary thoracic spinal metastasis from small-cell lung cancer. S. Katsenos, M. Nikolopoulou. Lung cancer with intramedullary spinal cord metastasis (ISCM) is a rare event exhibiting dismal prognosis. In the present paper, we describe a 74-year-old male who developed bilateral leg weakness with associated backache and non-productive cough. Chest imaging evaluation demonstrated pronounced bilateral mediastinal lymphadenopathy and a nodular opacity in the right lower lobe. The patient was diagnosed with small cell lung cancer through bronchoscopic procedures. Magnetic resonance imaging of the spinal cord with contrast-enhancement revealed an intramedullary lesion consistent with metastasis at the T5-T6 level. Despite chemotherapy and thoracic spine radiotherapy, he eventually succumbed to the disease 3 months after diagnosis. A brief overview of the current literature is also provided laying emphasis on the therapeutic strategies of this unusual extrathoracic metastatic disease.

Nsclc Patients

Molecular target therapies have markedly improved the survival of non-small cell lung cancer (NSCLC) patients, especially those with epidermal growth factor receptor (EGFR) mutations. A positive EGFR mutation is even more critical when the chronicity of spinal metastasis is considered. However, most prognostic models that estimate the life expectancy of spinal metastasis patients do not include these biological factors. We retrospectively reviewed 85 consecutive NSCLC patients who underwent palliative surgical treatment for spinal metastases to evaluate the following: (1) the prognostic value of positive EGFR mutation and the chronicity of spinal metastasis, and (2) the clinical significance of adding these two factors to an existing prognostic model, namely the New England Spinal Metastasis Score (NESMS). Among 85 patients, 38 (44.7%) were EGFR mutation-positive. Spinal metastasis presented as the initial manifestation of malignancy in 58 (68.2%) patients. The multivariate Cox proportional hazard model showed that the chronicity of spinal metastasis (hazard ratio (HR) = 1.88, p = 0.015) and EGFR mutation positivity (HR = 2.10, p = 0.002) were significantly associated with postoperative survival. The Uno’s C-index and time-dependent AUC 6 months following surgery significantly increased when these factors were added to NESMS (p = 0.004 and p = 0.022, respectively). In conclusion, biological factors provide an additional prognostic value for NSCLC patients with spinal metastasis.
