ABSTRACT
Objective:To observe the changes of serum progastrin-releasing peptide (Pro-GRP) and neuron specific enolase (NSE) levels in patients with small cell lung cancer (SCLC) in the concurrent chemoradiotherapy and their significances.Methods:The data of 80 patients with SCLC who were admitted to Shanxi Provincial Cancer Hospital from June 2018 to December 2019 were retrospectively analyzed, and the patients were divided into the concurrent chemoradiotherapy group (26 cases) and chemotherapy alone group (54 cases). Enzyme-linked immunosorbent assay (ELISA) and electrochemiluminescence method were used to detect serum Pro-GRP and NSE levels before and after treatment; and the association of Pro-GRP and NSE levels with patients' condition, treatment method, treatment stage and treatment efficacy was analyzed.Results:Among 80 patients with SCLC, Pro-GRP level of patients with limited-stage [127.43 pg/ml (17.61- 1 547.30 pg/ml)] was lower than that of patients with extensive-stage [547.87 pg/ml (20.20-2 111.00 pg/ml)], and the difference was statistically significant ( U = 312.65, P < 0.01). NSE level of patients with limited-stage [25.02 μg/L (4.72-64.64 μg/L)] was also lower than that of patients with extensive-stage [88.08 μg/L (5.52-104.64 μg/L)], and the difference was statistically significant ( U = 203.14, P < 0.01). The levels of Pro-GRP and NSE in the concurrent chemoradiotherapy group and the chemotherapy alone group were decreased after 2 and 4 cycles of chemotherapy compared with those before treatment, and the differences were statistically significant (all P < 0.01); the decrease range in the concurrent chemoradiotherapy group was more than that in the chemotherapy alone group, but the differences between the two groups were not statistically significant (all P > 0.05). The objective response rate in the concurrent chemoradiotherapy group was 96.15% (25/26), which was higher than that in the chemotherapy alone group [70.37% (38/54)], and the difference was statistically significant ( χ2 = 6.972, P = 0.008). Conclusions:The serum levels of Pro-GRP and NSE for patients with SCLC in the concurrent chemoradiotherapy can reflect the changes of the condition of SCLC patients. Concurrent chemoradiotherapy is more effective compared with the chemotherapy alone in the treatment of SCLC.
ABSTRACT
Objective To study the clinical efficacy of sodium cantharidinate and vitamin B6 injection combined with concurrent chemoradiotherapy in treatment of locally advanced nasopharyngeal carcinoma (LA-NPC).Methods 115 patients with LA-NPC in Shanxi Cancer Hospital were randomly assigned to observation group (61 cases) and control group (54 cases) from February 2014 to April 2016.The patients in the observation group were treated with sodium cantharidate and vitamin B6 injection combined with concurrent chemoradiotherapy.The patients in the control group were treated with concurrent chemoradiotherapy.The differences between the two groups were compared in respect of recent curative effect,the quality of life (QOL) and the adverse reactions.Results The recent effective rate was 93.44 ％ (57/61) in the observation group and 79.63 ％ (43/54) in the control group,and there was significant difference between the two groups (x2 =4.818,P =0.049).The improvement rate of QOL was 73.77 ％ (45/61) in the observation group and 53.70 ％ (29/54) in the control group,and there was significant difference between the two groups (x2 =5.028,P =0.032).The incidence rates of oral cavity mucous membrane inflammation,hematology toxicity,pharynx and esophagus adverse reactions,the gastrointestinal tract adverse reactions and skin fibrosis in the observation group were lower than those in the control group,and there were significant differences between the two groups (all P ＜ 0.05).Conclusion The recent effect of sodium cantharidinate and vitamin B6 injection combined with concurrent chemoradiotherapy on the patients with LA-NPC is obvious.The comprehensive treatment can also reduce adverse reactions and improve the QOL.
ABSTRACT
Objective To evaluate the efficacy and untoward effects of brucea javanica oil emulsion combined with radiotherapy in the treatment of patients with esophageal cancer. Methods 50 initial treatment patients with esophageal squamous cell carcinoma were randomly assigned to observation group (25 cases) and control group (25 cases). All patients were treated with three dimensional conformal intensity modulated radiation therapy (3D-IMRT) and the radiation dose was 64 Gy/32 times (95 % PTV). The patients in observation group received the treatment of brucea javanica oil emulsion during radiotherapy. The differences between the two groups were compared in respect of the efficacy, the adverse reactions and the quality of life (QOL). Results The effective rate in observation group was 92%(23/25) and it was 68%(17/25) in control group, there was significant difference between the two groups (χ2 = 4.500, P= 0.034). The incidence of radiation esophagitis at the level of RTOG2 and above in observation group was 20%(5/25) and it was 60%(15/25) in the control group, there was significant difference between the two groups (χ2= 8.333, P=0.004). The improvement rate of QOL in observation group was 68 % (17/25) and it was 40 % (10/25) in control group, there was significant difference between the two groups (χ2 = 3.945, P= 0.047). Conclusion Brucea javanica oil emulsion combined with radiotherapy for the treatment of patients with esophageal cancer can improve the therapeutic effect and QOL,it can also reduce radiation reactions.
ABSTRACT
Objective To explore the related factors of tumor regression speed during radiotherapy for esophageal cancer and analyze the relationship between recent clinical curative effect and tumor regression speed.Methods 68 previously untreated esophageal cancer patients were treated with three dimensional conformal intensity modulated radiation therapy (3D-IMRT).The radiation dose was 64 Gy/32 times (95 ％ PTV).All the patients were divided into 3 groups according to the size of primary lesions during the entire course of radiotherapy.Fast regression was defined as a complete response before dose 32 Gy,slow regression with dose in the range of 64 Gy and other cases as residual disease.The correlations of tumor regression speed with age,gender,classification,length of lesion and the lesion location were analyzed.And the relationship between recent clinical curative effect and tumor regression speed was discussed.Results The age,gender,classification and the lesion location were not associated with tumor regression (P ＞ 0.05).There was a negative correlation between tumor regression speed and the length of lesion [88.9 ％ (16/18),69.2 ％ (18/26) and 12.5 ％ (3/24) in fast,slow and residual group,respectively,x2 =27.923,P ＜ 0.05].There was a positive correlation between recent clinical curative effect and tumor regression speed (r =0.415,P ＜ 0.05).Conclusion The length of primary lesion is an independent risk factor for recent clinical curative effect and tumor regression speed of esophageal cancer patients treated with 3D-IMRT.
ABSTRACT
Objective To investigate the expression of Survivin gene and the relationship between Survivin and genesis and development of cervical cancer. Methods The expression of Survivin gene in tissues of 40 patients with cervical cancer, 38 patients with cervical hyperplasia and 10 cases of normal cervical were detected by immunohistochemical SP method, and the relationships between Survivin and the clinical pathological factors were analyzed. Results The expression positive rate of Survivin in cervical cancer tissues (60 %) was significantly higher than that in cervical hyperplasia and normal cervical tissues (42.1 % and 0, respectively), and their differences were statistically significant (P < 0.05). The positive expression rate of Survivin was related with histological grade and the clinical stages of cervical cancer.Conclusion Survivin is related to the genesis and development of cervical cancer.
ABSTRACT
Objective To investigate the correlation of pathology factors and prognosis of gastrointestinal stroma tumors (GIST). Methods The expression of CD117, CD34, SMA, S-100 and Ki-67 in 91 GIST cases were studied by Envision method of immunohistocbemistory;Sequently, the relationship of the location, the size, the hemorrhage, cellular necrosis, stroma mucus, the mitosis, Ki-67 expression and the prognosis were analyzed by SPSS 12.0. Results The positive rate of CD117, CD34, SMA, S-100 were 80.21%, 73.63 %, 34.07 %, 7.69 % respectively. There had significant difference between the location, the mitosis, Ki-67 expression and the prognosis; but no significant difference between the location, the hemorrhage, cellular necrosis, stroma mucus, CD117 expression and the prognosis. Conclusion The tumor's size, mitosis, and Ki-67 expression are associated with prognosis; CD117 expression and prognosis. Even more, Ki-67 expression may be a more precise factor to judge the tumor's biological behaviour compared to the mitosis. As a wally classified method, the Flecther classification is worth to spread.
ABSTRACT
Objecfive Most prostate cancer contains two or more widely separate turnors.To study the origin of prostate cancer based on the analysis of microsatellite alteration in separate tumors from the same prostate.Methods A polymerase chain reaction (PCR) was used to examine the allelic loss pattern of 4 microsatellite polymorphic markers on chromosome 8p (D8S133,D8S136,D8S137) and 17q (D17S855) in multifocal tumors of prostate from 19 patients.DNA samples were obtained from different regions of distinctly separate tumors on single case using microdissection technique.Results The overall frequence of LOH at D8S133,D8S136,D8S137 and D17S855 for all informative cases was 74%,38%,86% and 46%respectively in 40 separate tumors of prostate from 19 patients.The pattern of allelic loss was not identical in 15 of 18 (83%) informative cases. It showed that the different regions of prostate cancer were independent origin respectively.Discordant pattern of histology was observe in distantly separate regions.whereas the same allele was consistently lost in samples from different regions of the same tumor in 3 cases. Condusion Current data supports independent origin of multiple tumors in most prostate cancer patients.
