Summary
KTP 532 laser excision effectively treats early oral cancers without reconstruction, showing high survival rates and minimal recurrence. This laser surgery offers a precise alternative with better patient outcomes.
Area of Science:
- Oncology
- Surgical Oncology
- Laser Medicine
Background:
- Oral malignancy presents significant treatment challenges.
- Conventional surgical approaches may involve extensive reconstruction and morbidity.
- Minimally invasive techniques are sought to improve patient outcomes.
Purpose of the Study:
- To evaluate the efficacy of KTP 532 laser in surgically managing early and early-advanced oral cancers.
- To assess outcomes without the need for primary site surgical reconstruction.
- To determine the safety and effectiveness of laser-assisted tumor excision.
Main Methods:
- Retrospective analysis of 67 patients with T1, T2, and early T3 oral malignancy (2000-2013).
- Tumor excision performed using KTP 532 laser, with or without neck dissection or adjuvant radiotherapy.
- Wound healing by secondary intention without reconstruction.
Main Results:
- High rate of no loco-regional residual disease (61/67 cases) at last follow-up.
- Overall mean survival of 81 months, with 3-year disease-free survival at 91%.
- Laser excision demonstrated precision, reduced morbidity, shorter hospital stays, and better functional results.
Conclusions:
- KTP 532 laser excision is a viable alternative for early oral malignancy treatment.
- This technique offers advantages in precision, reduced morbidity, and improved functional outcomes.
- Laser-assisted surgery provides a less invasive option compared to conventional methods.
