RESUMO

Objective To evaluate the effect of time between surgery and postoperative radiation therapy on local recurrence of squamous cell carcinoma of the tongue and floor of the mouth. Methods A total of 154 patients treated between 1996 and 2007 were selected considering local recurrence rate and time of the adjuvant radiotherapy. Results Local recurrence was diagnosed in 54 (35%) patients. Radiation therapy reduced the rate of local recurrences, although with no statistical significance. The time between surgery and initiation of postoperative radiotherapy did not significantly influence the risk of local recurrence in patients referred to adjuvant treatment (p=0.49). Conclusion In the presence of risk factors for local recurrence, a short delay in starting the adjuvant radiation therapy does not contraindicate its performance. .


Objetivo Avaliar o efeito do tempo entre o tratamento cirúrgico e a radioterapia pós-operatória nas recidivas locais do carcinoma epidermoide de língua e soalho da boca. Métodos Foram selecionados 154 pacientes tratados entre 1996 e 2007, considerando a frequência das recidivas locais e o tempo para início da radioterapia adjuvante. Resultados As recidivas locais foram diagnosticadas em 54 (35%) pacientes. A radioterapia reduziu a frequência de recidivas locais, embora sem significância estatística. O tempo entre a cirurgia e o início da radioterapia pós-operatória não influenciaram, de forma significante, no risco de recidivas locais entre o pacientes que tinham indicação de tratamento adjuvante (p=0,49). Conclusão Na presença de fatores de risco para recidiva local, um pequeno atraso no início da radioterapia adjuvante não contra-indica sua realização. .

RESUMO

Objective To analyze the therapeutic effects of different treatment modalities in patients with tongue squamous cell carcinoma.Methods A retrospective analysis was performed on the complete clinical and follow-up data of 132 patients with pathologically confirmed tongue squamous cell carcinoma,who were initially treated at the First Affiliated Hospital of Xinjiang Medical University from 2003 to 2011.The Kaplan-Meier method was used to calculate the overall survival (OS) rates for patients who received surgery alone (S),radiotherapy alone (R),surgery plus radiotherapy (S + R),chemotherapy plus surgery (C + S),chemotherapy plus radiotherapy (C + R),and surgery,radiotherapy,and chemotherapy (S + R + C).The OS was compared between these groups by log-rank test.Multivariate analysis was performed using the Cox proportional hazard model to establish independent treatment modalities as prognostic factors.Results The follow-up rate was 100%.The 3-year sample size was 94.The 3-year OS rate for all patients was 72.7%.The univariate analysis showed that among 70 stage Ⅰ and Ⅱ patients,the S,R,S + R,C + S,and S + R + C groups had 3-year OS rates of 86%,67%,97%,100%,and 82%,respectively (P =0.018) ;among 62 stage Ⅲ and Ⅳ patients,the S,R,S + R,C + S,C + R,and S + R + C groups had 3-year OS rates of 38%,14%,92%,40%,14%,and 67%,respectively (P =0.000).The multivariate analysis showed that S + R and S + R + C were independent prognostic factors (P =0.000 and 0.005).onclusions Surgery alone or combination therapy including surgery has a good therapeutic effect for stage Ⅰ-Ⅱ tongue squamous cell carcinoma,while S + R and S + R + C are better treatment modalities for stage Ⅲ-Ⅳ disease;however,advanced patients have a poor prognosis after being treated with R and C + R modalities.
