Abstract:
ObjectiveTo evaluate the outcomes and toxicities of elderly nasopharyngeal carcinoma (NPC) treated with conventional radiotherapy alone.MethodsFrom January 1995 to December 1998,95 newly diagnosed nasopharyngeai carcinoma with age ≥65 years treated in our hospital.The clinical data were analyzed retrospectively.Kaplan-Meier method was used for analysis of local-regional control survival and distant metastasis-free survival. The Logrank test was used for univariate prognostic analysis and Cox regression was used for multivariable prognostic analysis.ResultsThe follow-up rate was 98%.The 3-,5- and 8-year local-regional control (LRC) and distant metastasis-free survival (DMFS) rates were 89%,87%,84% and 85%,79%,79%,respectively. The most common acute toxicities were grade1-2 leukopenia (36%),skin reaction (64%) and mucositis (66%).The most frequent late toxicities were hearing impairment (8%),trismus ( 10% ) and radiation-induced cranial neuropathy (5%).In univariate analysis,interruption of radiotherapy ( χ2 =7.45,P =0.006 ) and regional neck lymph nodes response (χ2 =4.17,P=0.041 ) was the prognostic factors for LRC,T stage (χ2 =4.16,P=0.032),N stage ( χ2 =4.66,P =0.031 ) and interruption of radiotherapy ( χ2 =9.42,P =0.002 ) was the prognostic factors for DMFS. In multivariable analysis,interruption of radiotherapy and the regional neck lymph nodes response were the prognostic factors for LRC (χ2=6.19,P=0.013 and χ2=12.16,P=0.002;respectively),N stage and radiotherapy interruption were prognostic factors for DMFS.(χ2=15.06,P =0.000 and χ2 =21.62,P =0.000 ; respectively ).ConclusionsConventional radiotherapy alone for elder NPC can produce satisfactory results with acceptable treatment-relative toxicities.Our experience showed that the early N stage,without radiotherapy interruption and good regional lymph nodes response had a good longterm prognosis.
