Objective:To evaluate the value of preoperative peripheral blood neutrophil-lymphocyte ratio (NLR) and blood platelet-lymphocyte ratio (PLR) and immune indexes in the evaluation of the prognosis of cervical cancer patients.Methods:The clinical data of 283 patients with cervical cancer who underwent radical surgery in Shanxi Province Cancer Hospital from May 2017 to September 2018 were retrospectively analyzed, and 100 healthy people who underwent physical examination during the same period were collected as the healthy control group. Test results of blood cells and immune cells expressions of all subjects were collected. Peripheral blood NLR and PLR of cervical cancer patients, people in the healthy control group and cervical cancer patients with different pathological characteristics were compared. Kaplan-Meier method was used to make survival analysis and Cox regression risk model was used to analyze the factors influencing the prognosis of patients with cervical cancer.Results:The preoperative peripheral blood NLR and PLR in patients with cervical cancer was higher than that of the healthy control group (NLR: 2.53±1.35 vs. 2.00±1.21, t = 5.35, P < 0.001; PLR: 163±57 vs.144±38, t = 4.71, P = 0.006). Pathological results showed that there were no statistically significant differences in NLR and PLR in peripheral blood of cervical cancer patients with different pathological types, tumor diameter, vascular invasion, and nerve invasion (all P > 0.05), while there were statistically significant differences in NLR and PLR in peripheral blood of cervical cancer patients with different clinical staging and muscle wall invasion (all P < 0.05). When the proportions of the expression levels of preoperative CD3 positive cells, CD4 positive cells, CD8 positive cells, CD19 positive cells, CD56 positive cells, and CD127 positive cells were 60%-85%, 30%-40%, < 25%, 8%-15%, 15%-25% and < 5%, respectively, the overall survival of cervical cancer patients was the best. Univariate analysis showed that pathological type, clinical staging, vascular invasion, preoperative NLR, preoperative PLR,CD3 positive cells, CD4 positive cells, CD8 positive cells, CD19 positive cells, CD56 positive cells and CD127 positive cells were influencing factors of the overall survival of cervical cancer patients (all P < 0.05). Multivariate analysis showed that clinical staging, vascular invasion, preoperative NLR, preoperative PLR, and preoperative CD4 positive cells were independent influencing factors for the overall survival of cervical cancer patients (all P < 0.05). Conclusions:Preoperative high NLR and PLR in peripheral blood have a certain impact on the clinicopathological characteristics and poor prognosis of cervical cancer patients. When the immune cells in peripheral blood are in dynamic balance, the prognosis of cervical cancer patients is the best.

Objective:To explore the differences in clinicopathological features, survival status and prognostic influencing factors of breast cancer patients with different molecular subtypes, and to provide bases for the prevention and treatment of breast cancer.Methods:The clinicopathological data of new-onset female breast cancer patients hospitalized in Shanxi Province Cancer Hospital from January 2015 to December 2016 were retrospectively analyzed, and patients were followed up. The clinicopathological features of patients with different molecular subtypes were compared. The follow-up was performed until June 30, 2021. Kaplan-Meier method was used to analyze the survival of patients, and Cox proportional hazards model was used to analyze the factors affecting overall survival (OS) of patients with different molecular subtypes.Results:There were 272 (14.9%), 1 005 (55.2%), 277 (15.2%) and 268 (14.7%) patients with subtypes of Luminal A, Luminal B, human epidermal growth factor receptor 2 (HER2) overexpression and triple-negative breast cancer (TNBC), respectively. The differences in the distribution of patients with age at diagnosis, age at menarche, menopausal status, age at menopause, pathological type, longest tumor diameter, T staging, N staging, histological grading, and TNM staging were statistically significant among the four groups (all P < 0.05). At a median follow-up of 60 months, the 5-year OS rates of Luminal A, Luminal B, HER2 overexpression and TNBC subtypes were 93.8%, 89.2%, 77.6% and 78.0%, respectively, and the difference was statistically significant ( χ2 = 58.76, P < 0.001). M staging was an independent influencing factor for OS in patients with Luminal A breast cancer ( HR = 16.789, 95% CI 4.972-56.690, P < 0.001); T staging ( HR = 2.721, 95% CI 1.715-4.319), N staging ( HR = 4.460, 95% CI 2.399-8.291) and M staging ( HR = 3.364, 95% CI 1.988-6.670) were independent influencing factors for OS in patients with Luminal B breast cancer (all P < 0.001); N staging ( HR = 4.428, 95% CI 1.836-10.677) and M staging ( HR = 13.489, 95% CI 6.043-30.107) were independent influencing factors for OS of patients with HER2 overexpression breast cancer (both P < 0.01); T staging ( HR = 3.052, 95% CI 1.575-5.915), N staging ( HR = 2.492, 95% CI 1.298-4.785) and M staging ( HR = 33.012, 95% CI 8.606-126.637) were independent influencing factors for OS of patients with TNBC (all P < 0.01). Conclusions:The clinicopathological features and prognostic influencing factors of breast cancer patients with different molecular subtypes are different, and the prognosis of HER2 overexpression and TNBC patients is poor. Clinicians should provide individualized treatment and follow-up programs for patients with different molecular subtypes of breast cancer.

Objective:To investigate the association between breast cancer and thyroid diseases, and to provide evidence for the prevention and treatment of thyroid diseases in breast cancer patients.Methods:A total of 511 newly diagnosed breast cancer patients were recruited between March 2018 and August 2019 from Shanxi Province Cancer Hospital, and 303 age-matched newly diagnosed breast benign disease patients and 341 age-matched healthy controls were recruited during the same time-frame. Thyroid B-ultrasound and thyroid function test were performed in the three groups. By reviewing the medical records, the general and clinicopathological data of the patients were collected, and the differences in the prevalence of thyroid diseases among the three groups were compared. The changes of thyroid function in breast cancer patients before treatment, in the middle stage of chemotherapy and at the end of chemotherapy were compared.Results:Among breast cancer group, breast benign disease group and healthy control group, the differences in the prevalence rates of hypothyroidism [32.5% (166/511), 25.7% (78/303) and 21.7% (74/341)], thyroid nodules [50.7% (259/511), 43.2% (131/303) and 41.6% (142/341)] and Thyroid Imaging Reports and Data System(TI-RADS) grade 4 and above thyroid nodules [15.4% (40/259), 14.5% (19/131) and 4.9% (7/142)] were statistically significant (all P < 0.05). The abnormal rates of thyroid stimulating hormone (TSH) and free thyroxine (fT4) in breast cancer group were higher than those in breast benign disease group and healthy control group [34.1% (174/511) vs. 26.1% (79/303), 23.5% (80/341); 24.9% (127/511) vs. 8.6% (26/303), 3.2% (11/341)], and the differences were statistically significant (both P < 0.05). The levels of fT4, free three iodide thyroxine (fT3), thyroid immunoglobulin antibody (TgAb) and thyroid peroxidase antibody (TPOAb) in breast cancer patients before treatment, in the middle stage of chemotherapy and at the end of chemotherapy were statistically different (all P < 0.05). The abnormal rates of fT4, TgAb and TPOAb in the last chemotherapy cycle were lower than those before chemotherapy [11.5% (59/511) vs. 24.9% (127/511), 5.1% (26/511) vs. 17.4% (89/511), 11.9% (61/511) vs. 20.4% (104/511)] in breast cancer patients, and the differences were statistically significant (all P < 0.001). Conclusions:The breast cancer is associated with thyroid diseases. Clinicians should pay more attention to the changes of thyroid diseases and thyroid function during the treatment and in the follow-up process of breast cancer patients, so as to detect the thyroid diseases early and carry out standardized treatment.

Objective:To explore the clinicopathological characteristics and factors influencing the survival of young breast cancer patients with diagnostic age below 35 years, and to provide the basis for the prevention and treatment of young breast cancer patients.Methods:Epidemiological and clinicopathological data of young female patients with newly diagnosed breast cancer from Shanxi Province Cancer Hospital between January 2015 and December 2016 were retrospectively analyzed. The data included age at diagnosis, reproductive history, history of abortion, menopausal status, and immunohistochemical results. Univariate and multivariate analysis were performed by using Cox regression model.Results:A total of 118 young breast cancer patients were collected, and the median age was 31 years old. Among them, the vast majority of 118 young breast cancer patients were invasive cancer (113 cases, accounting for 95.8%); there were 65 cases (55.1%) with tumor diameter ≤ 20 mm, 61 cases (51.7%) at N 0 stage, and 112 cases (94.9%) at M 0 stage. The positive rates of estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor receptor-2 (HER2) were 73.7% (87/118), 69.5% (82/118) and 28.8% (34/118), respectively. Luminal B breast cancer was the predominant molecular subtype, accounting for 55.1% (65/118). By the end of follow-up (median follow-up period of 60 months), the overall survival rate of young breast cancer patients was 78.8%. Multivariate analysis showed that TNM staging was an independent factor affecting overall survival in young breast cancer patients ( HR = 7.858, 95% CI 2.924-21.120, P < 0.001). Conclusions:Young breast cancer patients have unique clinicopathological features and TNM staging is an independent factor affecting the prognosis. Individualized treatment helps to improve the quality of life and prolong the survival time of patients.

Objective:The aim of the study was to investigate the association between epidermal growth factor receptor (EGFR) mutation and chemotherapeutic efficacy in advanced non-small cell lung cancer (NSCLC) patients.Methods:A total number of 490 patients with advanced non-small cell lung cancer were investigated in this retrospective study. Clinical outcomes were analyzed according to EGFR mutation status and mutation type based on Kaplan-Meier method and Cox regression model.Results:EGFR mutation was detected in 202 (41.2%) NSCLC patients. There was a trend that EGFR mutant patients had a higher response rate compared with wild type NSCLC patients, with non statistical significance (72.8% versus 66.0%, P=0.11). No difference was observed in progression free survival of first-line chemotherapy between EGFR negative and positive patients (6.00 versus 6.13 months, P=0.55). Patients harboring exon 19 deletion and exon 21 L858R point mutation derived similar progression free survival (PFS) (5.97 versus 6.23 months, P=0.79). Conclusions:EGFR mutation status and mutation type are not prognostic factors to first-line platinum-based chemotherapy in advanced NSCLC.

Breast cancer and thyroid diseases mostly occur in women, and both have seriously affected women's physical and mental health. Breast cancer patients have a higher risk of thyroid diseases before and after the onset of the disease compared with other malignant tumors. There are some common risk factors between them, and breast and thyroid are hormone-responsive organs, so they can also influence each other in some regulatory pathways. Iodine, thyroid hormone receptor and estrogen receptor are considered to be the possible pathogenesis of breast cancer. This paper explores the relationship between breast cancer and thyroid diseases with the help of researches in breast cancer, thyroid benign diseases, thyroid cancer, thyroid hormones and antibodies in recent years, so as to provide a basis for disease prevention and treatment.

Objective:To investigate the levels of glypican 3 (GPC3) and alpha-fetoprotein (AFP) in the serum of patients with primary liver cancer and its diagnostic value in liver cancer.Methods:A total of 277 patients with primary liver cancer, 108 patients with gastric cancer, 40 patients with hepatitis alone, 19 patients with hepatitis combined with other cancers other than liver cancer and 54 healthy controls in Shanxi Provincial Cancer Hospital between June 2018 and January 2019 were collected. The serum samples from all patients were taken. Enzyme linked immunosorbent assay (ELISA) was used to detect GPC3 level in all specimens. Electrochemiluminescence was used to detect the level of AFP. The diagnostic value of GPC3 or AFP alone and a combination of both for liver cancer was also compared. The relationship between GPC3 and AFP was also analyzed.Results:The serum GPC3 level [median (interquartile range)] in primary liver cancer, gastric cancer, the hepatitis only, the hepatitis combined with other cancer and healthy control was 0.079 ng/ml (0.198 ng/ml), 0.048 ng/ml (0.044 ng/ml), 0.073 ng/ml (0.053 ng/ml), 0.050 ng/ml (0.018 ng/ml), 0.023 ng/ml (0.011 ng/ml), respectively. The GPC3 level in the primary liver cancer was higher than that in the gastric cancer, hepatitis combined with other cancers other than liver cancer, the healthy controls (all P < 0.05), and there was no statistically significant difference in the level of GPC3 between the primary liver cancer and the hepatitis only ( P = 0.520). The sensitivity and specificity of GPC3 for the diagnosis of primary liver cancer was 69.5% and 94.4%, respectively. The sensitivity and specificity of AFP for the diagnosis of primary liver cancer was 63.9% and 94.0%, respectively. The sensitivity and specificity of the combined detection of liver cancer was 80.2% and 94.3%, respectively. The ratio of positive likelihood ratio and negative likelihood ratio was 38.42, 27.73 and 67.01, respectively in liver cancer diagnosed with GPC3, AFP and both of them. The expression of serum GPC3 was associated with AFP ( r = 0.34, P < 0.01). Conclusions:The detection of GPC3 combined with AFP can increase the detection rate of primary liver cancer, and it has a certain clinical significance in the early screening and diagnosis of primary liver cancer.

Objective: The aim of the study was to investigate association of response depth and prognosis in epidermal growth factor receptor (EGFR)-mutant non-small cell lung cancer (NSCLC)patients treated with first-line tyrosine kinase inhibitors (TKIs). Methods: The clinicopathological data and prognosis information of patients with locally advanced or metastatic (ⅢB or Ⅳ) lung adenocarcinoma with EGFR classical (19del or 21L858R) mutation who were treated in our hospital from 2015 to 2016 were collected. The tumor remission depth [stable disease (SD), partial response (PR), complete response (CR)] was measured by recist 1.1 standard. The survival curve was drawn by Kaplan-Meier method and log rank test was performed. Results: During the study period, 204 advanced lung adenocarcinoma patients with 19del or 21L858R mutation were treated with TKI drugs of the first generation. Among them, 24 patients were lost or unable to evaluate the efficacy, 20 patients were evaluated as progression disease (PD), 62 patients as SD, 98 patients as CR or PR. Disease control rate (DCR) and objective remission rate (ORR) were 88.9% and 54.4%, respectively. The median progression free survival time (PFS) was 12.6 months (95% CI: 10.9-14.4 months) and 13.1 months (95% CI: 11.6-14.7) for patients assessed as SD (group A) and CR or PR (group B), respectively, with no significant difference (P=0.27). Subgroup analysis showed that the median overall survival of patients with EGFR 19del and 21L858R mutations was 12.5 months (95% CI: 9.9-15.4) and 12.7 months (95% CI: 9.4-16.1), respectively, with no significant difference (P=0.66); Similar result was also observed in Group B with a median PFS of 13.9 months (95% CI: 12.3-15.5 months) and 12.3 months (95% CI: 9.5-15.1 months) in patients who had EGFR 19del or 21L858R mutations (P=0.41). Conclusions Response depth was not a positive predictor for prognosis in EGFR-mutant NSCLC patients treated with first-line TKIs.

Objective To explore the correlation between lymphatic metastasis and central lymph node metastasis and pre-surgery levels of serum thyrotropin (TSH), thyrobolulin (TG), anti-thyrobolulin antibodies (A-TG), anti-thyroid peroxidase antibodies (A-TPO) in patients with papillary thyroid carcinoma (PTC). Methods The clinical characteristics such as sex, age, tumor diameter, and some markers of thyroid function detection in 289 simple PTC cases were retrospectively analyzed, and their roles in lymphatic metastasis and central lymph node metastasis were discussed. Results Age < 45 years old (χ2= 5.86, P =0.02),multifocal(χ2=38.95, P<0.001), serum increased A-TG level(χ2=13.31,P <0.001) or A-TPO level (χ2= 7.30, P< 0.01) leaded to higher rate of lymphatic metastasis. Different TSH levels had different impact on lymphatic metastasis (χ2= 11.81, P = 0.02). When at 1.81-2.52 mU/L, the lowest rate of lymphatic metastasis was 34.68 %. Multivariable logistic regression analysis showed that focus (OR= 3.29, 95 % CI 1.85-5.52) and serum A-TG level (OR= 2.17, 95 % CI 1.11-4.26) were risk factors, whereas TSH at 1.81-2.52 mIU/L was more safe factor in simple PTC cases with lymphatic metastasis (OR= 0.28,95 % CI 0.09-0.85). Different groups of age (χ2= 11.54, P= 0.001), focal (χ2= 38.95, P< 0.001), serum TG level (χ2=9.01, P=0.01), A-TG level (χ2=14.51, P <0.001) or A-TPO level (χ2= 6.78, P= 0.02) leaded to statistically different central lymph node metastasis ending; further analysis showed that age (OR= 0.96, 95 % CI 0.94-0.98) and focus (OR= 5.47, 95 % CI 3.09-9.69) were risk factors of central lymph node metastatic in PTC patients. Conclusion Higher pre-surgery serum A-TG level and multifocal predict lymphatic metastasis, TSH level in 1.81-2.52 mU/L indicates lower rate of lymphatic metastasis, but age<45 years old and multifocal PTC patients are apt to occur central lymph node metastasis.

Objective To investigate the association between the positive rate of circulating tumor cells (CTC) and clinicopathological parameters, recurrence and metastasis in patients with colorectal cancer. Methods 7.5 ml peripheral blood of 138 cases of newly diagnosed colorectal cancer who met inclusion criteria, 82 post-operative cases of colorectal cancer and 34 healthy controls were collected. The CTC was enriched by beads which packaged the anti epithelial cell adhesion molecule and counting the CTC (CK+ DAPI+ CD45-). To investigate the association between the preoperative positive rate of CTC and clinicopathological parameters, and the relationship between the positive rate of CTC and recurrence and metastasis in post-operative colorectal cancer patients who have not accepted any therapy more than one month. Results The positive rate of CTC in patients with colorectal cancer and healthy controls were 47.1%(65/138), and 0 (0/34) respectively, and the difference was statistically significant (χ2= 25.743, P< 0.001). No association between CTC positive rate and age, gender, primary tumor site, T staging, platelets, cancer embolus, NK cells, regulatory T cell was observed (all P> 0.05); The significant association between the positive rate of CTC and N or M staging was found. CTC positive rates in N0, N1, N2 stage were 38.3 %(23/60), 37.9 % (11/29), and 63.9 % (23/36) respectively (χ2= 6.819, P= 0.033); CTCs positive rates of M0, M1 stage were 38 . 0 % ( 38/100 ) and 71 . 1 % ( 27/38 ) respectively , and there was a statistical difference (χ2= 12.074, P= 0.001). In 82 post-operative cases of colorectal cancer, the positive rates of CTC were 51.6 % (32/62) and 90.0 % (18/20) in non-recurrence and recurrence, respectively, and the difference was statistically significant (χ2=9.365, P=0.002). Conclusion CTC detection may assess the occurrence of metastasis and recurrence in colorectal cancer patients.
