Survival rates of patients with cancer of the lip, mouth and pharynx: a cohort study of 10 years

Abstract

Introduction: Cancer of the lip, mouth and pharynx is a serious health problem. High incidence rates are found worldwide. In Brazil, the Southern and Southeastern regions have the highest incidences in the country. Objective: To describe 5 and 10-year survival rates in patients with cancer of the lip, mouth and pharynx at a referral center in Florianopolis, Santa Catarina, Brazil. Methods: Retrospective cohort study using data from patients diagnosed between January 1 st and December 31 st , 2001, with follow-up until December 31 st , 2011. Descriptive analysis was performed and survival was estimated by Kaplan-Meier method. Cox semiparametric model was used to estimate death risk. Results: Survival rates at 5 and 10 years were 33.3 and 26.9%, respectively. Advanced clinical stage in the diagnosis increased death risk by 2.88 and 2.51, respectively. Sex, ethnicity, level of education, previous diagnosis and treatment, as well as age, did not show significant association. Conclusion: Survival rate at 5 years was 33.3% and, at 10 years, was 26.9%. Advanced stage was an independent risk factor for death due to cancer of the lip, mouth and pharynx in both periods analyzed.

Survival trends of patients with oral and oropharyngeal cancer treated at a cancer center in São Paulo, Brazil

“…In Chile, the survival estimate for OC was 46% in private hospitals (11). In Brazil, Santa Catarina reported a 5-year OS for OC and pharyngeal cancer of 33.3% (12). In Maceio, northeast of Brazil, the 5-year OS for oropharyngeal cancer was 27.8% (12,13).…”

In Santa Maria, south of Brazil, the 5-year OS for OC and oropharyngeal cancer was 42%; however, patients with oropharyngeal cancer had the worst survival rates (14).…”

Oral cancer in Brazil: dentists' lack of technical knowledge

“…We have recently published an article showing that the 5-year survival rate in patients with cancer of the lips, mouth, and pharynx was only 33.3% in a cohort treated at the main referral center in the state of Santa Catarina, Brazil. 2 The survival rate at 10 years was even lower (26.9%).…”

Primāras mutes dobuma rekonstrukcijas ar mikrovaskulāriem lēveriem pacientiem ar mutes vēzi vēlīnās stadijās, ietekme uz pacientu dzīvildzi un dzīves kvalitāti. Promocijas darba kopsavilkums

“…Pasaulē 5 gadu dzīvildzes dati pacientiem ar mutes vēzi vēlīnās stadijās ir dažādi, kas būtu skaidrojams ar veselības aprūpes pieejamību, sabiedrības izglītības līmeni un labklājību noteiktajā reģionā. Schneider et al savā pētījumā, analizējot Brazīlijā ārstēto pacientu 5 gadu dzīvildzi, konstatēja, ka pacientiem ar vēlīnās stadijas mutes vēzi 5 gadu dzīvildze ir 30,8% (Schneider, Flores et al 2014). Savukārt Vašingtonas Universitātē veiktais pētījums rāda, ka ārstēto pacientu ar mutes vēzi 5 gadu dzīvildze ir 57% (Sessions, Spector et al 2002).…”
