Totally implantable venous access port implantation in a breast cancer patient with situs inversus totalis: A case report.

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
Situs inversus totalis, a rare congenital condition characterized by complete mirror-image transposition of the thoracic and abdominal organs, has not previously been reported in patients with breast cancer. A 60-year-old woman with a 5-year history of left breast nodules was admitted. Contrast-enhanced breast magnetic resonance imaging and abdominal ultrasound revealed mirror-image transposition of the thoracic and abdominal organs. The patient was diagnosed with left breast cancer concomitant with situs inversus totalis. Preimplantation computed tomography revealed that the left internal jugular vein followed a straighter course to the right atrium than the right internal jugular vein. Under ultrasound guidance, a totally implantable venous access port was successfully placed via the left internal jugular vein. Neoadjuvant taxotere adriblastina cyclophosphamide chemotherapy was subsequently administered through the totally implantable venous access port before the patient underwent modified radical mastectomy for left breast cancer. Given the mirror-image anatomy, the anatomically relocated left internal jugular vein should be preferentially selected for totally implantable venous access port placement because of its more favorable anatomical course compared with the right internal jugular vein. To the best of our knowledge, this is the first reported case of totally implantable venous access port implantation in a patient with breast cancer and concurrent situs inversus totalis.
