Purpose : This study was performed to find out the prognostic factors affecting local
control, survival and disease free survival rate in nasopharyngeal carcinomas treated
with chemotherapy and radiation therapy.
Materials and Methods : analysed 47 patients of nasopharyngeal carcinomas,
histologically confirmed and treated at Chonnam University Hospital between July 1986
and June 1996, retrospectively. Range of patients' age were from 10 to 80 years
(median; 52 years). Thirty three (70%) patients was male. Histological types were
composed of 3 (6%) keratinizing, 30 (64%) nonkeratinizing squamous cell carcinoma and
13 (28%) undifferentiated carcinoma. Histological type was not known in 1 patient (2%).
We restaged according to the staging system of 1997 American Joint Committee on
Cancer. Forty seven patients were recorded as follows: T1; 11 (23%), T2a; 6 (13%),
T2b; 9 (19%), T3; 7 (15%), T4; 14 (30%), and NO; 7 (15%), N1; 14 (30%), N2; 21
(45%), N3; 5 (10%). Clinical staging was grouped as follows: Stage ¥°; 2 (4%), ¥±A; 2
(4%), ¥±B; 10 (21%), ¥²; 14 (30%), IVA; 14(30%) and IVB; 5 (11%). Radiation therapy
was done using 6 MV and 10 MV X- ray of linear accelerator. Electron beam was used
for the lymph nodes of posterior neck after 4500 cGy. The range of total radiation dose
delivered to the primary tumor was from 6120 to 7920 cGy (median; 7020 cGy).
Neoadiuvant chemotherapy was performed with cisplatin£«5-fluorouracil (25 patients) or
cisplatin£«pepleomycin (17 patients) with one to three cycles. Five patients did not
received chemotherapy. Local control rate, survival and disease free survival rate were
calculated by Kaplan-Meier method. Generalized Wilcoxon test was used to evaluate the
difference of survival rates between groups. Multivariate analysis using Cox proportional
hazard model was done for finding prognostic factors.
Results : Local control rate was 81% in 5 year. Five year survival rate was 60%
(median survival: 106 months). We included age, sex, cranial nerve deficit, histologic
type, stage group, chemotherapy, elapsed days between chemotherapy and radiotherapy,
total radiation dose, period of radiotherapy as potential prognostic factors in multivariate
analysis. As a result, cranial none deficit (p=0.004) had statistical significance in local
control rate. Stage group and total radiation dose were significant prognostic factors in
survival (p=0.006, p=0.012), and in disease free survival rates (p=0.003, p=0.008),
respectively. Common complications were xerostomia, tooth and ear problems.
Hypothyroidism was developed in 2 patients.
Conclusion : In our study, cranial nerve deficit was a significant prognostic factor in
local control rate, and stage group and total radiation dose were significant factors in
both survival and disease free survival of nasopharyngeal carcinoma. We have concluded
that chemotherapy and radiotherapy used in our patients were effective without any
serious complication.
