Objective: To evaluate the role of partial laryngectomy to treat glottic cancer after failure of radiation therapy.
Design: A 12-year retrospective outcome analysis.
Setting: University referral center.
Patients: A total of 19 patients who underwent partial laryngectomy to treat glottic cancer after failure of radiation therapy.
Results: The follow-up period in this group ranged from 31 to 144 months. After surgery, a laryngocutaneous fistula was observed in 4 cases, and flap necrosis occurred in 2, but these complications were successfully managed. Maximum phonation time after surgery ranged from 3 to 28 seconds (median phonation time, 10.2 seconds). Of these 19 patients, 3 developed local recurrence. These cases were successfully treated with total laryngectomy. A surgical margin of less than 1 mm was found to be a significant risk factor for local recurrence after partial laryngectomy.
Conclusions: These results indicate that partial laryngectomy is a useful option for the treatment of irradiation failure in the treatment of stage I and stage II vocal cord carcinomas. However, careful follow-up is mandatory for patients with a small surgical margin.

Purpose Of Review: To summarize current evidence regarding the indication of adjuvant treatment after transoral laser microsurgery (TOLMS).
Recent Findings: Apart from well known risk factors, margins represent the key point in the decision-making. If margins are affected, additional treatment is mandatory.

To investigate optimal treatment strategy for pT3N0 laryngeal squamous cell carcinoma（SCC）. A retrospective study of 150 patients with pT3N0 laryngeal SCC treated in the First Affiliated Hospital of Chongqing Medical University was performed. The efficacies of partial laryngectomy and total laryngectomy, as well as surgery alone and postoperative radiotherapy were evaluated.

Objective: To evaluate whether supracricoid partial laryngectomy (SCPL) may be a viable alternative to radiation therapy (RT) for patients with glottic cT3N0M0 squamous cell carcinoma (SCC) who are surgical candidates for total laryngectomy (TL) and respond well to platinum-based induction chemotherapy.
Methods: Retrospective case series review of 18 consecutive patients with cT3N0M0 glottic SCC, initially considered surgical candidates only for TL who showed a good response to platinum-based induction chemotherapy, managed at a French university teaching institution with either SCPL (n = 9) or RT (n = 9). The main endpoints were 10-year local control and laryngeal preservation.
