Treatment outcomes of patients with primary tracheal tumors - analysis of a large retrospective series.

OBJECTIVE: Primary tracheal tumors are very rare and their management is not definitely established. Due to its rarity, providing patient care in terms of optimal management poses a considerable challenge. The purpose of this study was to investigate treatment outcomes in patients with these rare tumors. METHODS: We carried out a retrospective analysis of 89 patients with primary tracheal tumors treated at the Maria Sklodowska-Curie National Research Institute of Oncology in Warsaw, Poland, over sixteen years. The study assessed patient demographics, tumor characteristics and treatment. Different treatment options were compared in terms of overall survival, disease-free survival, and progression-free survival. RESULTS: A total of 89 patients were included in the study. In the group presented, 45 patients underwent primary radical treatment and 44 were qualified for palliative treatment. Surgical resection was performed in 13 patients out of radically treated patients. The 5 year OS rates in the group of patients who underwent radical treatment and in the group of patients who underwent palliative treatment were 45.9% and 2.3%, respectively. In the group of patients who underwent radical surgical treatment, the 5 year OS was 76.9% compared to 35.8% in the group of patients who underwent nonsurgical treatment. CONCLUSION: A multidisciplinary team should decide treatment options, including in-depth consideration of surgical treatment options.

Clinicopathological characteristics of patients with primary tracheal tumors: Analysis of eighty-nine cases.

BACKGROUND: Primary tracheal tumors are very rare and the literature on this subject is limited. The most common histological type of primary tracheal tumors is squamous cell carcinoma (SCC), followed by adenoid cystic carcinoma (ACC). Limited knowledge exists regarding the behavior and outcomes of different histological types of tracheal cancers. The present study aimed to address this gap by assessing the significance of the histological type of primary tracheal tumors based on our own data and to review the literature. METHODS: We carried out a retrospective analysis of 89 patients with primary tracheal tumors treated at the Maria Sklodowska-Curie National Research Institute of Oncology in Warsaw, Poland, between 2000 and 2016. The study assessed patient demographics, tumor characteristics and treatment, with a focus on SCC, ACC, and other histological types. Different histological types were compared in terms of overall survival, disease-free survival, and progression-free survival. RESULTS: SCC was the most frequently diagnosed histological type (56.2%), followed by ACC (21.3%). Patients with SCC were typically older (78% over 60 years), predominantly male (66%), and associated with smoking. In contrast, the ACC had a more balanced gender distribution and did not correlate with smoking. ACC displayed a significantly better prognosis, with a median overall survival of 129.4 months, compared with 9.0 months for SCC. CONCLUSION: Histological type plays a crucial role in the prognosis of primary tracheal tumors. ACC demonstrated a more favorable outcome compared with SCC.
