⁶⁸Ga-DOTA⁰-Tyr³-octreotide positron emission tomography in head and neck squamous cell carcinoma.
Article in European journal of nuclear medicine and molecular imaging, 2013. 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
purpose⁶⁸Ga-labelled DOTA⁰-Tyr³-octreotide positron emission tomography (PET)/CT (⁶⁸Ga-DOTATOC PET/CT) is a routinely used imaging modality for neuroendocrine tumours expressing somatostatin receptors (SSTRs). Recent studies have shown that SSTRs are also expressed in head and neck squamous cell carcinoma (HNSCC). This is the first prospective clinical trial investigating SSTR expression in patients with HNSCC using ⁶⁸Ga-DOTATOC.
methodsPatients with previously untreated HNSCC underwent ⁶⁸Ga-DOTATOC PET/CT (120 MBq, range 81-150 MBq). Tumour tracer uptake was scored, the maximum standardized uptake value (SUVmax) was measured and the tumour to background uptake ratio was calculated. For each patient, PET/CT findings were correlated with immunohistochemical SSTR expression in tumour specimens.
resultsFifteen HNSCC patients were included in the study from May 2011 to May 2012. Tumour-specific ⁶⁸Ga-DOTATOC uptake was detected in all patients with an median SUVmax of 4.0 (range 2.2-6.5). Uptake was weak in seven (47%), moderate in five (33%) and strong in three (20%) patients. All tumour specimens were SSTR positive on immunohistochemistry. Of the 15 patients, 14 were positive for SSTR subtype 2, characterized by the highest affinity to octreotide.
conclusionSSTR expression in HNSCC can be visualized clinically using ⁶⁸Ga-DOTATOC PET/CT. SSTR expression in HNSCC could provide a potential target for SSTR-based therapy in patients not amenable to standard treatment modalities, but this cannot be predicted by SSTR immunohistochemistry.
