Study on Demography, Imaging and Histologic Classification in Patients with Nasopharyngeal Carcinoma

To explore the demographic features and histologic classification of nasopharyngeal carcinoma. Object Method: (non-kerаtinizing differentiаted cаrcinomа, non-kerаtinizing undifferentiаted cаrcinomа, nerаtinizing squаmous cell cаrcinomа). Results: cаrcinomа.

Step 1: Make a list of cases diagnosed with nasopharyngeal carcinoma diagnosed at oncology hospital, Ho Chi Minh city, using pathological results. ii.
Step 2: Statistics and data processing.

Discussion
According to the results in Table 1, the nasopharyngeal carcinoma rate gradually increases from the age of 20-40 years, reaching the highest peak in the age group 40-60 years, accounting for 58.9% and then the age group 60-80 years accounting for the rate of 17.7%. The youngest is 23, and the oldest is 80 years old.
With our research results, the age group most often affected by nasopharyngeal carcinoma is the age group of 40-60 years old, with a rate of 58.9%. This result is higher than that of author Dang Thanh (40%) [5] and lower than that of Pham Nguyen Tuong (65.3%) [6].
According to author Nguyen Trong Minh, et al. [7] the age group 40-50 years old has a high incidence of disease [7]. According to author Ngo Ngoc Lien, the common age group is 30-50 years old [8]. According to author Zong et al., the common age is 40-59 years old [9]. The age group of prostate cancer patients in our study is quite consistent with the above authors. According to the results in Hung, the symptoms of nasal congestion were 54.84% [15]. Our research results are still lower than the authors' results. According to our research, the symptoms of cranial nerve damage accounts for 8.5%. According to author Nguyen Thi Bich Thuy, the symptoms of cranial nerve damage accounts for 8% [14]. Our research results are relatively consistent with the results of the above author. According to some authors, the probability of detecting cervical lymph nodes is 85-90%, of which the lymph nodes of the two sides account for 50% [16]. In our research results, the clinical findings of cervical lymphadenopathy were 74.4%, of which the cervical lymph nodes were 37.1%. According to author Skinner, et al., Bilateral lymph nodes have a detection rate of 43% [16].
Our research results are relatively consistent with the results of the above author. The clinical prevalence of lymph node not detected was 25.6%. According to author Dang Thanh, the clinical examination did not see cervical lymph nodes accounting for 20% [5]. Our research results are quite consistent with the above author.
According to the results of  [17]. Our results agree with the two authors on the low rate of kerаtinizing squаmous cell cаrcinomа. The difference is that because we limited the sample before and after radiation therapy, so we lost a lot of samples not treated or treated by other methods, which made the difference in the proportion of pathological tissues in the study.

Conclusion
The study subjects had 141 patients. Men accounted for 75.9%, ages 40-<60 years old majority. History of smoking and drinking alcohol accounts for a high proportion for men. Clinical examination with the above lymph node accounted for the highest proportion.
Clinically diagnosed in almost cases of nasopharyngeal carcinoma.
