title: Long-Term Results of Partial Laryngectomized Patients.
abstract: OBJECTIVE
  This study was to present long-term oncological results, as well as the variables, that can increase nodal metastasis and reduce survival in patients diagnosed in the early and late stages of laryngeal cancer.
  
  
  METHODS
  A total of 85 patients were included in the study. These patients were grouped as supracricoid partial laryngectomy (PL), supraglottic horizontal PL, and vertical frontolateral PL. Furthermore, at least 3 years of the long-term outcomes of the patients in these 3 groups were compared.
  
  
  RESULTS
  Twenty-two of the patients (26%) had nodal metastasis, 16 (72%) of these patients were in Group I (P = 0.017); 14 patients (51%) had preepiglottic space (P = 0.075); 12 patients (50%) had paraglottic space involvement (P = 0.002); 9 (45%) patients with nodal metastasis had a depth of invasion more than 20 mm (P < 0.001). Out of the 16 patients who had positive intraoperative surgery margins, 5 (18%) of them had nodal metastasis (P = 0.589) and 14 (16%) patients were positive for perineural invasion, 3 (19%) of these patients had lymph node involvement (P = 0.074). One (5%) patient died with nodal metastasis. Median survival rate of all the patients was 44 ± 0.836 (42.36-45.63) months and the overall survival rate was 92.9%.
  
  
  CONCLUSIONS
  Paraglottic space involvement and tumor invasion depth were statistically effective on increased nodal metastasis. However, we suggest that depth of invasion may not be effective alone as a prognostic factor. In contrast to the known effect on overall survival was less lymph node.
