Clinicopathological characteristics of carcinoma from unknown primary in cervical lymph nodes.

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
Carcinoma in cervical lymph nodes of unknown origin represents a rare clinical entity where optimal diagnostic and therapeutic management is still a widely debated issue. Molecular classification of these metastases is thus of utmost importance. We analyzed the expression of eight basic molecular markers in 26 metastases from unknown primaries, 31 metastases from overt primaries and their associated primaries. Medical records of the respective patients were reviewed for main clinicopathological parameters. The expression rates showed no significant differences between the two tumor entities, neither in absolute terms nor in comparison among the parameters. Surprisingly, patients with metastases from unknown primary demonstrated improved progression-free survival (p = 0.046) despite advanced age (p = 0.029), advanced nodal stage (p = 0.006) and higher incidence of extracapsular spread (p = 0.045) compared to patients with metastases from overt primaries. Presence of extracapsular spread was associated with increased expression of epidermal growth factor receptor in metastases from overt primaries (p = 0.035) and reduced expression of matrix metalloproteinase-2 in metastases from unknown primary (p = 0.031). We thus conclude that cervical metastases from unknown and overt primaries show similarities in their molecular profile, but fundamental differences in clinical parameter.
