Partial laryngectomy following irradiation

H Sørensen, H S Hansen, K A Thomsen

    Summary

    Salvage partial laryngectomy after radiation therapy shows promise for glottic cancers. However, for supraglottic recurrences, total laryngectomy is preferred due to high morbidity with horizontal laryngectomy.

    Area of Science:

    • Otolaryngology
    • Surgical Oncology
    • Radiation Oncology

    Background:

    • Laryngectomy is a surgical option for laryngeal cancer.
    • Radiation therapy is a common treatment for laryngeal cancer.
    • Salvage surgery may be necessary for residual tumors or recurrences after radiation.

    Purpose of the Study:

    • To evaluate the outcomes of partial laryngectomy as a salvage procedure after radiation therapy.
    • To compare salvage partial laryngectomy with primary surgical operations.
    • To determine the optimal surgical approach for irradiation failures in different laryngeal subsites.

    Main Methods:

    • Retrospective review of 65 patients who underwent partial laryngectomy post-irradiation.
    • Comparison of outcomes between vertical laryngectomy (glottic) and horizontal laryngectomy (supraglottic).
    • Analysis of complication rates and functional outcomes.

    Main Results:

    • Vertical laryngectomy for glottic lesions yielded excellent results with no increased complication rate due to prior irradiation.
    • Horizontal laryngectomy for supraglottic tumors was associated with increased postoperative morbidity and significantly impaired function.
    • Total laryngectomy emerged as the preferred option for salvage in supraglottic recurrences post-irradiation.

    Conclusions:

    • Partial laryngectomy, specifically vertical laryngectomy, can be effective for salvage of glottic cancer after irradiation.
    • Horizontal laryngectomy for supraglottic salvage post-irradiation is associated with poor functional outcomes and high morbidity.
    • Total laryngectomy is recommended for irradiation failures in supraglottic laryngeal cancer.
