1 Isolated tumor cells in bone marrow predict reduced survival in node-negative non-small cell lung cancer  Bernward Passlick, MD, Boris Kubuschok, MD, Jakob R Izbicki, MD, Olaf Thetter, MD, Klaus Pantel, MD  The Annals of Thoracic Surgery  Volume 68, Issue 6, Pages (December 1999) DOI: /S (99)01125-X

2 Fig 1 Isolated CK18+ cell in the bone marrow of a patient with a resectable NSCLC (adenocarcinoma; pT1, pN0, M0). Alkaline phosphate-anti-alkaline phosphatase (APAAP) staining using monoclonal antibody CK2 against CK18; in order to facilitate the detection of immunocytochemical positive cells, no counter staining was done. The Annals of Thoracic Surgery  , DOI: ( /S (99)01125-X)

3 Fig 2 Frequency of CK18+ tumor cells in bone marrow of patients with completely resected NSCLC. The Annals of Thoracic Surgery  , DOI: ( /S (99)01125-X)

4 Fig 3 Overall survival (Kaplan-Meier analysis) in pN0 patients (n = 66) with surgically resected NSCLC depending on the presence (thick line) or absence (thin line) of immunocytochemically CK18+ tumor cells (≥ 2 cells per 4 × 105) in bone marrow. The difference is significant: p = by log-rank test. The Annals of Thoracic Surgery  , DOI: ( /S (99)01125-X)
