Cervical Lymph Node Metastasis As the Initial Manifestation of Colorectal Cancer: Progression to Complete Clinical Response After Systemic Treatment.
Article in Cureus, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Colorectal cancer has well-established metastatic patterns, with the liver and lungs being the most frequent sites of dissemination. Cervical lymph node involvement as an initial manifestation is extremely rare and represents a significant diagnostic challenge. We describe the case of a 68-year-old female patient with no relevant comorbidities, who initially presented with left cervical lymphadenopathy at levels IV and V, associated with weight loss and a marked elevation of carcinoembryonic antigen. Histopathological examination of the cervical lymph node confirmed metastatic adenocarcinoma, and after extension studies and colonoscopy were performed, a primary tumor was identified in the transverse colon. The patient began systemic treatment with a chemotherapy regimen based on capecitabine and oxaliplatin (XELOX) in combination with bevacizumab. Subsequently, after completing the induction phase, maintenance treatment with capecitabine plus bevacizumab was administered. During follow-up, the patient showed a gradual and sustained response, ultimately achieving a complete clinical response, confirmed by imaging studies, including computed tomography, colonoscopy, and positron emission tomography (PET). This case highlights the importance of considering a gastrointestinal origin in patients with atypical cervical lymphadenopathy, as well as the impact of combined systemic treatment and maintenance therapy in achieving complete responses, even in unusual presentations of metastatic disease.
