P3.13-024 - Is Alveolar Spread May Be Predictive with PET CT Scanning? (ID 9921)
09:30 - 09:30 | Author(s): O. Falay
- Abstract
Background:
In this study we aim to investigate predictivity of alveolar spread in primary lung cancer by using preoperatively scanning methods
Method:
In order to re-evaluate alveolar spread, pathology preparations of 45 patients had operated for primary lung cancer diagnosis and scanned preoperatively with PET CT all in our hospital which interpreted by same nuclear medicine specialists implicated in this study. As using the patients pet CT findings, CTV (computerized tomography volume), MTV (metabolic tumor volume), TLG(total lesion glycolysis), SUDmax, SUDort values and their relation with alveolar spread analyzed
Result:
Preoperatively PET-CT scanned all in our hospital 45 patients has included and cause of couldn't reach their pathological preparations, 6 of them exluded from the study. 21 of 39 patients were men (53.8%) , 18 of them were women (46.2%) and mean age was 66.67/+-7.88 (42-80). We didn't detect any relation between CTV, MTV, TLG, SUDmax, SUDort values and alveolar spread (p>0.05). However when the CTV/ MTV ratio analyzed, alveolar spread was statistically more common in the group of patients had ratio lower than 1. (62.9% versus 0% , p:0.01)
Conclusion:
High local recurrence risk in sublober rejected patients with alveolar spread has indicated in various studies. Regarding this matter, we recommend re-evaluation of the patients for sublober rejections whose CTV/MTV ratio is lower than 1.
