Molecular biological markers and micrometastasis in resected non-small-cell lung cancer. Prognostic implications.
Article in The Japanese journal of thoracic and cardiovascular surgery : official publication of the Japanese Association for Thoracic Surgery = Nihon Kyobu Geka Gakkai zasshi, 2001. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectivesRecent advances in molecular biology and genetics have created new diagnostic and treatment possibilities in clinical oncology. We evaluated the usefulness of molecular biological factors in primary tumor and micrometastasis in the bone marrow and pathological negative (pN0) lymph nodes as prognostic parameters in non-small-cell lung cancer (NSCLC) patients.
methodsPathological specimens were collected from 129 NSCLC patients to analyze molecular biological markers, including K-ras, p53, Rb, p16, loss of heterozygosity (LOH) at 3p, vascular endothelial growth factor (VEGF), and telomerase activity. Bone marrow samples from 250 NSCLC patients and pN0 lymph nodes from 85 of these patients were collected for micrometastasis detection by immunohistochemistry against cytokeratin.
resultsp53 abnormalities and 3p LOH were significantly associated with reduced patient survival in adenocarcinoma, whereas VEGF expression was significantly associated with reduced survival in a squamous cell carcinoma histological subtype by univariate or multivariate analysis. We identified micrometastatic tumor cells in bone marrow of 78 (31.2%) of 250 patients and in pN0 lymph nodes of 26 (30.6%) of 85 patients. Both bone marrow and lymph nodal micrometastases were associated with decreased survival among patients with stage I, however, only lymph nodal micrometastasis had a significant impact on survival.
conclusionsMolecular biological features of primary tumor and micrometastatic status appear useful in defining groups of patients with a poor prognosis who could benefit from adjuvant systemic treatment.
