Prognostic factors for survival and nonfunctional larynx in patients with squamous cell carcinoma of the larynx

Abstract

Objectives/Hypothesis: Prognostic variables upon presentation can assist in recommending the optimal treatment for patients and may help in management of patient's expectations and side effects. Our objective was to evaluate prognostic factors for survival and nonfunctional larynx in patients with laryngeal squamous cell carcinoma (SCC). in a tertiary, university-affiliated medical center were reviewed. Main outcomes were survival and nonfunctional larynx rate.Results: Two hundred sixty-five patients were identified; the male:female ratio was 4.5:1. Mean age at diagnosis was 64 AE 11.8 years. Overall and disease-free survival were 7.9 and 6.7 years, respectively. A univariate analysis found that older age significantly affected survival. Alcohol abuse, diabetes mellitus, and advanced disease stage at presentation were also found to decrease survival but were not significant. A multivariate Cox regression found age, alcohol abuse, and advanced disease stage to significantly affect and lower survival (P < .05). Of the entire cohort 19% were defined as having a nonfunctional larynx (e.g., tracheostomy or feeding-tube dependent). A backward logistic regression found that male sex and advanced disease stage increased the risk, and anterior commissure involvement was found to lower the probability of nonfunctional larynx (P < .01).Conclusions: Older age, history of alcohol use, and advanced disease stage at presentation negatively affect survival in larynx cancer patients. Male gender and advanced disease stage increased the risk, and anterior commissure involvement was found to lower the risk for tracheostomy or feeding-tube dependency.

The deubiquitinase USP34 stabilizes SOX2 and induces cell survival and drug resistance in laryngeal squamous cell carcinoma

“…With the development of therapy technology, the survival rate and quality of life of patients with LSCC have been greatly improved. 13 However, the recurrence, metastasis, and insensitivity to radiotherapy or chemoresistance often lead to poor therapeutic effects for LSCC, which cannot be solved by traditional therapies. 14,15 Therefore, it is urgent to identify novel targets for the treatment of LSCC.…”

Reduction in healthcare services during the COVID-19 pandemic: Patient screening based on symptoms is an effective strategy for avoiding delayed laryngeal cancer diagnosis

“…Laryngeal squamous cell carcinoma (SCC) is the most frequent head and neck cancer. Advanced stages are the strongest negative prognostic factors and requires more aggressive treatments [2] . Therefore, it is imperative to early diagnose and promptly treat it.…”

Development and Validation of an Immune-Related Signature for the Prediction of Recurrence Risk of Patients With Laryngeal Cancer

“…Even if salvage whole laryngectomy or re-radiotherapy is taken, patients who relapse within 2 years after initial treatment may still die from recurrence ( 3 ). Some clinical indicators have been reported as prognostic predictors for patients with recurrent head and neck carcinoma such as presence or absence of complications as well as tumor cell differentiation ( 4 ). Thus, how to reduce mortality and risk of recurrence remains a major clinical challenge for head and neck surgeons ( 5 ).…”
