[Abstract]:Changes in nasopharyngeal carcinoma radiotherapy and chemotherapy in the process of nutritional status and related blood indexes: through the analysis of nasopharyngeal carcinoma radiotherapy and chemotherapy in the process of nutritional status and related blood index changes, radiotherapy and to understand the impact of chemotherapy on the nutritional status of patients with nasopharyngeal carcinoma, and to discuss the reliable monitoring factors of malnutrition in nasopharyngeal carcinoma. Methods: a retrospective analysis of 134 cases of nasopharyngeal carcinoma patients with initial treatment in August 2010 -2011 year in December the Department of radiation oncology Affiliated Hospital of Guangxi Medical University, which meet the following conditions: 18 years of age; pathological diagnosis of non keratinizing nasopharyngeal carcinoma radiotherapy using IMRT (intensity-modulated radiotherapy IMRT) technology, to exclude distant metastases and other malignant tumors history. With complete personal information, nutritional status and related blood indicators: information age and gender, disease history, smoking, drinking, nutritional support, height, KPS score (Karnofsky performance status, KPS), chemotherapy, body mass index (Body mass index BMI TNM (Tumor-node), clinical stage, pathological metastasis classification) type and nutritional risk screening (Nutritional risk, screening, NRS) in patients with subjective global assessment (Patient-generated subjective global assessment, PG-SGA) of qualitative and quantitative determination, hematological indicators such as total protein (Total, Protein, TP), serum albumin (albumin, ALB), immunoglobulins (Globulin, GLOB), iron protein (Transferrin, TRF), creatinine (Creatinine, Cre), blood urea nitrogen (Blood urea, nitrogen, BUN), platelet (Blood platelet, PLT), white blood cell (White blood cell, WBC), neutrophil count (Neutro Phil count, NC), lymphocyte count (Lymphocyte count, LC), red blood cell (Red blood corpuscle, RBC), hemoglobin (Hemoglobin, Hb) level. To investigate the changes of nutritional status and related hematological indexes in patients with nasopharyngeal carcinoma during radiotherapy and chemotherapy. For a normal distribution or approximate normal distribution of the data is measured by the mean and standard deviation (s) in the form of description, comparison between groups at different time points of the quantitative data by variance analysis, further use of LSD-t to test the 22 comparison, correlation with Pearson correlation analysis and Spearman test analysis the hematological indicators of NRS2002 and PG-SGA- and qualitative, 0.05 said the difference was statistically significant. Results: l and nasopharyngeal carcinoma patients had 5.97% (8/134) of BMI18.5 before radiotherapy and chemotherapy, and 27.61% (37/134) patients lost 5% of their weight in the past 3 months. The total score of NRS is greater than or equal to 3 points (i.e., risk of malnutrition need nutritional support therapy) 30.6% patients (41/134), PG-SGA- qualitative C grade (9 minute) was 3.73% (5/134), B (2-8) was 43.28% (58/134). 2. in the mid-term of radiotherapy, 11.9% (16/134) was found in patients with BMI18.5 (low weight malnutrition), and the proportion of people with weight loss was -5.45%~11.32%, with an average of 2.4%. Among them, the weight loss was 82.09% (110/134), more than 5% accounted for 21.64% (29/134), and 7.46% (10/134) was reduced by more than 10%. Score of NRS were higher than 3 in 75.37% (101/134), PG-SGA- qualitative C grade (9 minute) was 20.9% (28/134), B (2-8) was 55.97% (75/134). 3 at the end of radiotherapy, 18.66% (25/134) of BMI18.5 patients (low weight dystrophy) were found. The range of weight loss was -3.64%~19.51%, with an average of 6.27%. Among them, the weight loss was 89.55% (120/134), more than 5% accounted for 32.09% (43/134), and 28.36% (38/134) was reduced by more than 10%. The total score of NRS is greater than or equal to 3 points with 85.82% (115/134), PG-SGA- qualitative C grade (9 minute) was 32.09% (43/134), B (2-8) was 58.96% (79/134). 4. compared with before treatment, patients with nasopharyngeal carcinoma radiotherapy in the middle and at the end of radiotherapy, body mass index, NRS and PG-SGA were significantly worse than before (p0.001), corresponding to the hematological indexes, but no obvious change of creatinine, total protein, serum albumin, globulin, urea nitrogen, leukocyte, neutrophil count, lymphocyte count, erythrocyte, hemoglobin levels decreased progressively, ferritin increased, the difference was statistically significant (p0.001). 5. pre - treatment albumin and NRS2002 score, red blood cell and hemoglobin, NRS2002 score and PG-SGA score were negatively correlated (p0.001). The total protein, albumin and hemoglobin at the 4 week of treatment were negatively correlated with PG-SGA (p0.001). At the end of treatment, WBC, neutrophil count, lymphocyte count, red blood cell and hemoglobin and NRS2002 score were negatively correlated, while the total protein and albumin and PG-SGA score were negatively correlated, white blood cells, neutrophils, lymphocytes and red blood cells and red blood protein and PG-SGA score was negatively correlated. Conclusion: Patients with nasopharyngeal carcinoma have a higher risk of malnutrition before treatment. During the concurrent radiotherapy and chemotherapy, the corresponding nutritional status and hematological indexes all showed continuous deterioration. Albumin, red blood cells and hemoglobin have a certain correlation with the nutritional status score, so it can be used as a monitoring factor for the nutritional status of patients. The second part is about the influencing factors of malnutrition in patients with nasopharyngeal carcinoma during concurrent chemoradiotherapy. Objective: To study the influencing factors of malnutrition in nasopharyngeal carcinoma patients during concurrent chemoradiotherapy. Methods: a retrospective analysis of 134 cases of newly diagnosed nasopharyngeal carcinoma with IMRT confirmed by pathology was performed. The tumor was measured on the MR images of 2 radiology doctors and radiology doctors before treatment. According to the extent of tumor invasion, the tumor boundaries were delineated on MRI, and the area of each tumor was obtained, and the Gross tumor volume (GTV) was calculated. Nasopharyngeal and neck MR images were used to record anatomical locations of tumor invasion: parapharyngeal space, palatine muscle / anterior vertebral muscles, nasal cavity, oropharynx, hypopharynx, skull base, pterygopalatine fossa, paranasal sinus, pterygoid muscle, lateral pterygoid muscle, and intracranial. According to the histopathological classification of WHO nasopharyngeal carcinoma in 1991, WHO- II and type III were selected and divided into two types.
