Yes "stable" is good. I can't wait.
I found the following - which explains some. If you haven't had surgery since STAS became official, your pathology report would not indicate it I suspect. WHO only made it official as a means of cancer spread in 2015. So then pathology reports started to carry that info.

Spread Through Air Spaces (STAS) in Lung Cancer: A Multiple-Perspective and Update Review Published 23 April 2020 Volume 2020:12 Pages 2743—27 Dovepress
Conclusion:
Above all, in this review, we comprehensively summarized current discoveries concerning STAS from multiple perspectives. STAS is a conspicuous spreading phenomenon of lung cancers indicating worse prognosis; nevertheless, the treatment strategy for patients with STAS remains to be discussed. Further studies are needed to elaborate whether a STAS-positive patient who underwent limited resection needs a second operation or postoperative adjuvant treatment. Meanwhile, although the nutrition resource has been studied, the internal mechanism of STAS formation is largely undiscovered. Whether the capability of detachment-migration-reattachment in STAS tumor cells is achieved at the time of primary tumorigenesis or in the progress of tumor development needs to be studied, and the related signal pathways or genetic alterations need to be explored. With this information, it may be possible to improve the prognosis of patients with STAS-positive lung cancers.
