RESUMO
BACKGROUND: Smoking and alcohol are the main risk factors for head and neck cancer. Despite the significant psychological impact, many patients continue to smoke and drink alcohol after diagnosis of cancer. This study aims to analyze the patients' behavior post diagnosis and treatment of head and neck cancer. METHODS: An observational retrospective study was conducted on patients suffering from head and neck cancer. Their smoking and alcohol habits before and after diagnosis of cancer were studied. RESULTS: A total of 85 patients were recruited: 80â¯% males, mean age 61.77±9.30 years. Among smokers, 35.80â¯% continued smoking post-diagnosis. A statistically significant correlation was found between smoking habit after diagnosis of cancer and type of treatment and tracheostomy. Among drinkers, 65.52â¯% continued to consume alcohol after diagnosis of cancer. A statistically significant correlation was found between alcohol consumption post-diagnosis and sex. CONCLUSIONS: Patients undergoing more invasive treatments are more likely to quit smoking and/or drinking alcohol, suggesting the strong psychological impact of cancer and its therapy. Many patients continue smoking and consuming alcohol due to unawareness, depression, or addiction. However, most patients reduced cigarette smoking and alcohol consumption. Comprehensive care, including psychological support, is essential for these patients.

PURPOSE: The overall survival of laryngeal squamous cell carcinoma (LSCC) hasn't changed significantly in the last decades, leading to a negative prognosis in advanced stages. So, the immunotherapy takes space with the inhibition of PD-1/PD-L1 checkpoint, involved in suppression of immune response. METHODS: A prospective study was conducted on LSCC patients, selected according to strict criteria. The study was approved by the ethics committee of our Hospital. Parameters were: sex, age, smoking and alcohol habits, C-reactive protein (CRP) level in the serum, laryngeal subsite involved, differentiation-based histopathologic grading of tumor, neck node involvement, tumor stage, expression levels of PD-L1 (as Combined Positive Score - CPS). P-value < 0.05 was statistically significant. RESULTS: 58 patients were included: 31.03% were females, mean age 63.55±10.09. A statistically significant correlation between CPS and smoking habits and N stage was found. CRP resulted increased in 44.83% of patients with a statistically significant correlation with CPS. The most cases were glottic cancers (46.55%). 75.86% of tumors were moderately-differentiated, without correlation with CPS. CONCLUSION: PD-L1 expression levels are variables independent of sex, age, alcohol consumption, differentiation degree of LSCC. A statistically significant correlation between PD-L1 expression levels and smoking habits, neck node status and CRP was found. This last finding demonstrates the involvement of PD-1/PD-L1 checkpoint in immune response in case of cancer. However, these results need further studies to detect the best patients tailored for treatment with anti-PD-1/PD-L1 blocking antibodies.
