To evaluate the perioperative morbidity and long-term oncological survival of local excision using the transanal endoscopic microsurgery (TEM) technique for sessile rectal adenomas and early rectal cancer, highlighting the differences in treatment approaches.
Key Findings:
TEM technique demonstrated low local recurrence rates for early distal rectal tumors, indicating its effectiveness.
Patients with benign lesions (Group A) required no further treatment post-excision, suggesting a favorable outcome.
Patients with high-risk (HR) or stage II lesions (Group B) were offered salvage surgery or adjuvant radiotherapy, highlighting the need for tailored treatment strategies.
Interpretation:
The study supports the use of local excision for selected rectal adenomas and early rectal cancers, emphasizing the importance of careful patient selection and surgical technique.
Limitations:
The study is limited to a single institution, which may affect the generalizability of the results; further multicenter studies are needed.
Long-term outcomes may vary based on patient demographics and tumor characteristics not fully addressed, which could influence treatment decisions.
Conclusion:
Local full-thickness excision using TEM is a viable option for treating sessile adenomas and early rectal cancer, with favorable long-term oncological outcomes, underscoring the importance of careful patient selection.
The Eugene M. & Christine E. Lynn Cancer Institute at Boca Raton Regional Hospital, part of Baptist Health, reached an important milestone in the advancement of cancer care with the successful treatment of its first patient utilizing proton therapy, according to physicians at both the Institute and the hospital.
