Eksperimentel: Postoperative radiotherapy
intensity modulated radiotherapy (IMRT)
|
Postoperative radiotherapy clinical target volume (CTV) design: The conventional postoperative laryngeal radiotherapy target is defined as CTV1, which encompasses the entire laryngeal structure, piriform sinus, gloss-epiglottic vallecula, paraglottic space, pre-epiglottic space, thyroid cartilage, and extends to the inferior border of the cricoid cartilage. For T2 tumours, CTV2 is delineated to include bilateral cervical lymph node regions II-III. PTV1 and PTV2 are defined as the regions expanded by 3 mm outward from CTV1 and CTV2, respectively. The prescribed dose for PTV1 is 60 Gy in 30 fractions (60 Gy/30F), and the prescribed dose for PTV2 is 54 Gy in 30 fractions (54 Gy/30F). |

Tidsramme |
|---|---|---|
|
3-year local-regional failure-free survival (LRFS)
Tidsramme: From the date of surgery to the date of local recurrence, , assessed up to 3 year.
|
3-year local-regional failure-free survival (LRFS): defined as the time from the date of surgery to recurrence of the primary lesion and perilesional tissues.
The index date for recurrence is the date when a measurable new lesion is first identified.
For patients who die of any other cause prior to documented disease recurrence, LRFS is calculated from the date of surgery to the date of death.
For patients without documented disease recurrence or death at the time of analysis (i.e., recurrence-free survivors), the time of the last efficacy assessment will be used as the endpoint.

Adverse events
Tidsramme: From enrollment to the end of treatment at 5 years.
|
The incidence, type, and severity of adverse events (AEs), serious AEs, and immune-related AEs (irAEs) were assessed in accordance with the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI-CTCAE version 5.0).
|
From enrollment to the end of treatment at 5 years.
|
|
5-year local-regional failure-free survival (LRFS)
Tidsramme: From the date of surgery to the date of local recurrence, assessed up to 5 year.
|

The index date for recurrence is the date when a measurable new lesion is first identified.

For patients without documented disease recurrence or death at the time of analysis (i.e., recurrence-free survivors), the time of the last efficacy assessment will be used as the endpoint.
|
From the date of surgery to the date of local recurrence, assessed up to 5 year.
|
|
5-year overall survival (OS)
Tidsramme: From the date of surgery until the date of surgery due to any cause, assessed up to 5 year.
|
Overall Survival(OS) is defined as the period from the date of surgery to the date of death due to any cause.
|
From the date of surgery until the date of surgery due to any cause, assessed up to 5 year.
|
|
5-year disease-free survival (DFS)
Tidsramme: Time from the date of surgery to any evidence of tumour growth or death, assessed up to 5 year.
|
5-year disease-free survival (DFS): defined as the time from the date of surgery during which the patient remains alive without evidence of tumour growth.
Recurrence is defined as the emergence of new lesions, including recurrence of the primary lesion and perilesional tissues, cervical lymph-node metastasis, and distant metastasis.
The index date for recurrence is the date on which a measurable new lesion is first identified.
For patients who die of any other cause prior to documented disease recurrence, DFS is calculated from the date of surgery to the date of death.
For patients with no documented disease recurrence or death at the time of analysis (i.e., disease-free survivors), the time of the last efficacy assessment will serve as the endpoint.
