Hypothesis
Can multispectral fluorescence imaging effectively distinguish lymphatic drainage patterns during robot-assisted lymph node dissection in prostate cancer patients?
Conclusion
Multispectral imaging can distinguish lymphatic drainage patterns, but fluorescein is unsuitable for confirming fluorescence at histopathology.
Supporting Evidence
- Fluorescein was visible in lymph vessels but not in tumor-positive nodes.
- Indocyanine green and fluorescein co-accumulated in lymph vessels in vivo.
- Administration of fluorescein did not result in discomfort or abnormal recovery.
Takeaway
Doctors used special cameras to see how lymph flows during prostate cancer surgery, helping them avoid unnecessary cuts.
Methodology
A prospective study involving 16 patients undergoing robot-assisted radical prostatectomy with multispectral fluorescence imaging.
Potential Biases
Potential bias due to varying surgeon experience and patient selection.
Limitations
Small sample size and single-center study may limit generalizability.
Participant Demographics
16 male patients, median age 66.5 years, with a calculated risk of lymph node invasion >5%.
