Does immunostaining effectively upstage colorectal cancer by identifying micrometastatic nodal disease?
Article in International journal of colorectal disease, 2007. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers, 1 of them a synthesis that pooled it.
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
purposeMeasure the association between the incidence of primary tumor staining and the identification of mediastinal lymph node (MLN) using cytokeratins, NM23, DCC-positive tumors, and vascular endothelial growth factor (VEGF) expression in T(2) and T(3)/N(0) colorectal cancers. The impact of MLN on both recurrence and survival was assessed. MATERIALS AND
methodsThere were 153 CORC patients (T(2), T(3)/N(0)) selected from a prospectively accrued database. All patients had been staged by routine histopathology after a curative resection and no patients received adjuvant chemotherapy. The primary tumors (PT) were assessed with a panel of immunohistochemical stains (cytokeratin, DCC, Nm23, and VEGF). If the PT was positive, the regional nodes were assessed with that marker(s). For any positive tumor marker, all lymph nodes (LNs, mean of 12.6+/-4.2) were stained for this marker.
resultsPatient age ranged from 38 to 86 years with a mean age of 61.56+/-25.56 years. Mean follow-up was 72.1+/-32.4 months. Recurrence rate of the whole group was 19/153 (12.4%) and the mean time to recurrence was 37.6+/-23.6 months (15 to 77 months). Crude mortality was 39.9%, while the cancer specific mortality was 11.2% after the whole follow-up period. The relationship between PT staining and MLNs was: cytokeratin-PT 143 (93.5%)/MLN 9 (6.3%); NM23-PT 51 (33.3%)/MLN 3 (5.9%); DCC-PT 79 (53%)/MLN 3 (3.8%); and VEGF-PT 72 (47%)/MLN 4 (5.6%). Nineteen (12.4%) patients experienced tumor recurrence. No correlation exist between PT and/or MLN staining and either recurrence or survival. No patient with MLN with any stain experienced a recurrence. There was no advantage to using an individual stain or all four stains.
conclusionImmunohistochemical stains for PT and focused analysis of regional nodes did not improve prediction of survival or recurrence. Sentinel LN evaluation and the provision of adjuvant chemotherapy in node-negative patients should be questioned and not be utilized outside of a research protocol.
