Tracheal cancer – treatment results, prognostic factors and incidence of other neoplasms

View Article: PubMed Central - PubMed

ABSTRACT

Background: Tracheal cancers (TC) are rare and treatment results that are reported are typically not satisfactory. The purpose of this research was assessment of the results of treatment of TC patients, identification of potential additional surgery candidates, evaluation of prognostic factors, and assessment of the occurrence of other malignancies.

Patients and methods: The Regional Cancer Database and the Hospital Database were searched for patients with tracheal neoplasms. Fifty-eight of 418 patients identified initially, met the inclusion criteria (primary TC with confirmed histology and complete treatment records). Standard statistical tests were used.

Results: Squamous cell carcinoma (SCC; 63.8%) and adenoid cystic carcinoma (ACC; 15.5%) were the most commonly diagnosed histological types of TC. Radiotherapy was delivered in 48 cases, surgery or endoscopic resection in 20, and chemotherapy in 14. TC was diagnosed as a second cancer in 10 patients, in 1 patient it occurred prior to the lung cancer, and in 1 was diagnosed simultaneously. During the median follow-up of 12.7 months, 85.5% of the patients died because of the disease. Local recurrence occurred in 17% cases. In univariate analysis, patients with ACC had statistically better five-year overall survival (77.8%) than those diagnosed with SCC (8.4%, p = 0.0001). Radiotherapy, performance status and haemoptysis were factors significantly influencing overall survival (OS) in the multivariate analysis. Among patients who were not treated surgically, 15–26% were found to constitute additional surgery candidates, depending on the selection criteria.

Conclusions: The diagnostic workup should be focused on the identification of TC patients suitable for invasive treatment and radiotherapy. Respiratory system cancer survivors can be considered a risk group for tracheal cancer. Radiotherapy constitutes an important part of the treatment of patients with TC.

Mentions: We conducted a retrospective study on patients diagnosed with TC in our institution between 1997 and 2015. The Regional Cancer Database and the Hospital Database were searched for patients with tracheal neoplasms. Among 418 patients (160 from the Regional Cancer Database and 258 from the Hospital Database), we found 58 cases that met the inclusion criteria (Figure 1).
