Axillary lymph node metastasis from papillary thyroid carcinoma with elevated CA 19-9 and CA 242 levels: a case report and literature review.
Article in Gland surgery, 2021. 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
Axillary lymph node metastasis is a rare event in thyroid carcinoma. The simultaneous expression of carbohydrate antigens 19-9 (CA 19-9) and 242 (CA 242) in thyroid tumors is also extremely rare. Herein, we report a case of axillary lymph node metastasis with elevated serum CA 19-9 and CA 242 in papillary thyroid carcinoma. In a 47-year-old woman with thyroid carcinoma, masses developed in the neck and axilla over a two-month period, which were surgically treated using total thyroidectomy, with neck and axillary lymph node dissection. Histopathological examination confirmed a diffuse sclerosing variant-papillary thyroid carcinoma, with 52 of 63 axillary lymph node metastases. Notably, serum CA 19-9 and CA 242 levels decreased from the initial values of 1,110 and 50 kU/L, respectively, to normal levels one month postoperatively and have remained stable for two years since. The aggressive biological behavior of diffuse sclerosing variant-papillary thyroid carcinoma and the abnormal anatomical distortion caused by tumors in this case most likely reflect the mechanisms underlying retrograde dissemination in lymphatic tubes. However, the mechanism leading to a simultaneous elevation of CA 19-9 and CA 242 secreted by the diffuse sclerosing variant-papillary thyroid carcinoma has not been elucidated. The patient has survived for two years suggesting that timely surgery can help such patients achieve a better prognosis.
