Analysis of dosimetry and clinical efficacy of intracavitary/interstitial brachytherapy in Ⅲ B cervical cancer / 中华放射肿瘤学杂志

Objective:To compare the dosimetry and efficacy of intracavitary brachytherapy (ICBT) and intracavitary/interstitial brachytherapy (IC+ ISBT) based on CT image guidance in the treatment of stage Ⅲ B cervical cancer. Methods:Clinical data of 93 patients with stage Ⅲ B cervical cancer treated in Department of Radiotherapy of Jilin Cancer Hospital from June 2014 to February 2017 were analyzed retrospectively. According to the results of Gynecological examination and pelvic MRI before brachytherapy, confirming the size of residual tumor and the degree of parauterine infiltration, all patients were divided into the ICBT and IC+ ISBT groups. The D 90%, D 100%, V 100% and D 2cm 3 of bladder and rectum were compared, and the short-term and long-term efficacy was observed between two groups. Results:The median follow-up time was 60 months. The 5-year local control rate, distant metastasis-free survival rate and overall survival rate of all patients were 83%, 71% and 68%, respectively. Compared with the ICBT group, HR-CTV D 90% in the IC+ ISBT group was all more than 85 Gy, while there was no significant difference between two groups ( P=0.188). The D 2cm 3 of bladder and rectum in the IC+ ISBT group was significantly decreased by 7 Gy and 8 Gy (both P<0.01), and the distant metastasis-free survival rate was significantly improved ( P=0.009). The 5-year local control rate in the HR-CTV volume>60 cm 3 in the IC+ ISBT group was significantly higher than that in the IC group ( P=0.029). Conclusion:For patients with Ⅲ B cervical cancer, IC+ ISBT can not only ensure target coverage, but also significantly reduce the incidence of distant metastasis and the dose of organs at risk, and significantly improve the local control rate of large tumors.

Influence of low-dose occupational radiation exposure on peripheral blood cells in radiation workers / 国际生物医学工程杂志

Objective:To investigate the effect of low-dose ionizing radiation on blood cell parameters of radiation workers.Methods:A total of 124 staff members engaged in radiology were selected into the observation group, and they were divided into 4 subgroups of physicians, physicists, technicians, and maintainer according to their jobs. A total of 130 non-radiation-related staff members from the same hospital were selected into the control group. Blood cell parameters of peripheral blood of all subjects from 2016 to 2019 were collected, and the differences in blood cell parameters between the radiation group and the control group as well as 4 subgroups of the control group were analyzed and compared, and the correlation between the differences in blood cell parameters and the cumulative radiation dose was compared.Results:Compared with the control group, the white blood cell count, neutrophil count, red blood cell count and hemoglobin count in the observation group were lower than those in the control group (all P<0.05). There are no significant differences in cumulative radiation dose among different types of work (all P>0.05). Correlation analysis showed that the blood cell parameters of peripheral blood cells were not significantly correlated with the cumulative radiation dose. The blood cell count changes after 4-year low-dose ionizing radiation between the physicist group, the technician group and the maintainer sub-group were significantly different (all P<0.05), but the above differences were not related to the cumulative radiation dose (all P>0.05). Conclusions:Under the same exposure and protection conditions, the blood cell counts of different radiation-related workers are not significantly different, and the long-term cumulative radiation dose has no significant correlation with blood cell parameters. Therefore, peripheral blood cell parameters can no longer be used as a good indicator to reflect radiation damage, and it is urgent to find more convenient, intuitive and sensitive indicators of radiation damage.

Interpretation of guideline for breast cancer screening in Chinese women / 中国肿瘤临床

Breast cancer is the most common cancer for Chinese women. Early screening is the best way to improve the rates of early diagnosis and early treatment of breast cancer. The peak ages of breast cancer in Chinese women are obviously different from those in the European and American countries. It is imperative to develop a guideline for breast cancer screening that is suitable for Chinese women. Based on the analysis and summary of breast cancer screening data in China, and the latest guidelines and consensus on breast cancer screening in Europe, the United States and East Asia, China Anti-Cancer Association and National Clinical Research Center for Cancer (Tianjin Medical University Cancer Institute and Hospital) has developed a population-based guideline for breast cancer screening in Chinese women. This guideline has provided detailed recommendations on the screening starting age, screening modalities, and screening interval in Chinese women with average risk and high risk of breast cancer, respectively. This article aims to interpret the above guideline, providing references for professionals in breast cancer screening.

Implication of BRCA1/2 gene detection in malignant tumors / 中国肿瘤临床

Tumor suppressor genes breast cancer gene 1/2 ( BRCA1/2) play key roles in DNA damage repair pathways and are essential for maintaining genome integrity. The earliest studies found that BRCA1/2 are the main pathogenic factors of hereditary breast/ovari-an cancer syndrome, and the risk of breast cancer and ovarian cancer is greatly increased in BRCA1/2 mutation carriers. Recent studies have demonstrated that BRCA1/2 mutations also increased the risk of developing colon cancer, pancreatic cancer, skin cancer, and male prostate cancer. BRCA1/2 mutation patients have common molecular pathological basis, which may be independent of pathologi-cal tissue diagnosis in the future. Furthermore, it can serve as an important basis for clinical drug therapy, including chemotherapy drugs represented by platinum, PARP inhibitors, PD-1 antibodies, ALDH2 inhibitors, and mTOR inhibitors.

Objective To explore the clinicopathological characteristics,diagnosis,treatment and prognosis of accessory breast cancer.Methods Clinical and pathological data of 37 accessory breast cancer patients from Dec 2005 to Aug 2017 were reviewed.Results 12 patients underwent breast-conserving local wide excision plus axillary lymph node dissection.5 cases were treated by segmental resection and 19 patients by Auchincloss or Halsted mastectomy;One patient abandoned surgery.The most common histological type of accessory breast cancer was infiltrating ductal carcinoma (26 cases,70.3％) followed by adenocarcinoma (4 cases) and miscellaneous type (7 cases).The most common AJCC pathological stages were stage Ⅱ (n =24,65 ％),Ⅰ (n =8),Ⅲ(n =3) and Ⅳ (n =2).The median follow-up time was 6 (1-12) years,the followup rate was 100％.Until Dec 2017,7 patients died from metastasis and the others were alive.Conclusions Accessory breast cancer is rare and with poor prognosis.The diagnosis depends on clinical manifestations,imaging and pathology.Surgery is the mainstay therapy,adjuvant chemo therapy is recommanded.

The association between the expression and activity of indoleamine 2,3-dioxygenase and the efficacy of neoadjuvant chemotherapy in patients with breast cancer / 中国肿瘤临床

Objective:To investigate the association between indoleamine 2,3-dioxygenase(IDO)expression in tumor tissue,its periph-eral blood activity, and the efficacy of neoadjuvant chemotherapyin patients with breast cancer. Methods: Immunohistochemistry (IHC)and high-performance liquid chromatography(HPLC)were used to measure IDO protein expression in tumor tissue,and kynuren-ine(Kyn),tryptophan(Trp),and IDO activity(Kyn/Trp)in peripheral blood before neoadjuvant chemotherapy in 53 patients with breast cancer from Tianjin Medical University Cancer Institute and Hospital between September 2015 and December 2016.The correlations between the expression and activity of IDO and the efficacy of chemotherapy were analyzed.Results:In tumor tissue,IDO expression-before neoadjuvant chemotherapy was related to clinical tumor stages(P=0.006),node stages(P=0.020),clinical stages(P=0.045),and estrogen receptor(ER)status(P=0.014).High IDO activity before neoadjuvant chemotherapy in peripheral blood was associated with high IDO expression in tumor tissue(P=0.004),and was also correlated with clinical tumor stages(P=0.019)and node stages(P=0.047). Univariate analysis showed that the clinical efficacy of neoadjuvant chemotherapy was associated with pre-chemotherapeutic clinical tumor stages(P=0.049),ER status(P=0.025),and molecular subtype(P=0.014),while pathologic complete response(pCR)was related to pre-chemotherapeutic clinical tumor stages(P=0.014).Importantly,the clinical efficacy of neoadjuvant chemotherapy and pCR were both related to IDO expression and activity before chemotherapy(all P<0.05).Multivariate analysis showed that pre-chemotherapeu-tic IDO activity in peripheral blood was the only independent factor that affected pCR(P=0.032).Conclusions:Tumor tissue IDO expres-sion and peripheral blood IDO activity before chemotherapy were associated with chemotherapy efficacy,and could provide promising information for the clinical prediction of chemotherapy sensitivity.

Effects of Moxibustion and Moxa Smoke on Blood Lipids, and Hepatic Pathologic Morphology and CD36 and ABCA1 Expressions in ApoE-/-mice / 上海针灸杂志

ObjectiveTo investigate the intervention effects of moxibustion and moxa smoke on blood lipids,hepatic pathological changes and intrahepatocytic molecules related to cholesterol metabolism and analyze the regulating effects of moxibustion and moxa smoke on cholesterol metabolism and explore the mechanisms of actions of moxibustion and moxa smoke. MethodFifty-one 8-week-old ApoE-/-mice were randomized into model, moxa smoke and moxibustion groups, 17 mice each. Twenty C57BL/6 mice comprised a blank control group. The normal and model groups of mice were routinely grabbed and fastened. The moxa smoke group of mice was exposed to 10-15 mg/m3moxa smoke circumstances. The moxibustion group of mice was given moxibustion on point Guanyuan(CV4). All interventions were made 20 min daily, 6 times a week, for 12 consecutive weeks. Total cholesterol (TC), triglyceride (TG), high density lipoprotein-cholesterol (HDL-C) and low density lipoprotein-cholesterol (LDL-C) were measured using an automatic biochemical analyzer. Hepatic pathologic morphology was observed by HE staining. Hepatic CD36 and ABCA1 expressions were determined by immunohistochemical method.ResultIn the model group of mice, serum TG and LDL-C contents were significantly higher than in the normal group (P=0.003;P=0.001);HDL-C content was significantly lower than in the normal group (P=0.007); TC content had no significant difference compared with the normal group (P>0.05). In the moxibustion group of mice, serum TG and LDL-C contents were significantly lower than in the model group (P=0.03;P=0.001) and HDL-C content had no significant difference compared with the model group (P=0.11). In the moxa smoke group of mice, serum TG and LDL contents were significantly lower than in the model group (P=0.01;P=0.008) and HDL content had no significant difference compared with the model group (P=0.11). There were no significant differences in various blood lipid indicators between the moxibustion and moxa smoke groups (P>0.05). There were hepatic cell cord and sinusoid derangement and obvious hepatocytic swelling in the model group of mice. In the moxa smoke and moxibustion groups, hepatocytic swelling subsided significantly, and inflammatory cell infiltration reduced compared with the model group. In the model group,CD36 expression was significantly higher than in the normal group (P=0.004) and ABCA1 expression was significantly lower than in the normal group (P=0.001). In the moxibustion group, CD36 expression had no significant difference compared with the model group (P=0.09) and ABCA1 expression was significantly higher than in the model group (P=0.03). In the moxa smoke group, CD36 expression was significantly lower than in the normal group (P=0.02) and ABCA1 expression was significantly higher than in the model group (P=0.002). There were no significant differences in CD36 and ABCA1 expressions between the moxibustion and moxa smoke groups (P>0.05).ConclusionEarly moxibustion on point Guanyuan can regulate disorders of blood lipid metabolism, delay the occurrence of hepatic lesions and reduce intrahepatic accumulation of cholesterol to a certain extent in an ApoE-/-mouse model of atherosclerosis. That may be one of the mechanisms by which moxibustion therapy prevents atherosclerosis. Moxa smoke as the product of moxibustion is an effective factor in moxibustion producing a therapeutic effect.

Micronucleus in vitro induced by inhalable particulate matters in moxa smoke / 中国针灸

<p><b>OBJECTIVE</b>To investigate whether inhalable particulate matters can cause the damage of chromosome or mitotic apparatus to produce micronucleus, and to evaluate genetic toxicology of moxa smoke on chromosome.</p><p><b>METHODS</b>By MTT method, the 24 h half maximal inhibitory concentration (IC50) of moxa smoke condensation (MSC) on Chinese hamster ovary (CHO) cells was 0.087 mg/mL. CHO cells, which were cultured in vitro, were divided into a solvent control group, a positive control group (cyclophosphamide as solvent), a low concentration group, a moderate concentration group and a high concentration group. The low concentration group, moderate concentration group and high concentration group were set approximately 1/8, 1/4, 1/2 of IC50, respectively. Whether micronucleus had dose-effect response induced by the damage of chromosome or mitotic apparatus was observed after CHO cells were contaminated by MSC in the low concentration group, moderate concentration group and high concentration group.</p><p><b>RESULTS</b>The rate of micronucleus induced by MSC in the low concentration group, moderate concentration group and high concentration group was higher than that in the solvent control group (all P < 0.05), which presented dosage-effect response. The experiment was repeated 3 times, indicating it was repeatable with statistical significance.</p><p><b>CONCLUSION</b>High concentration of MSC shows toxicity to induce chromosome damage, which disappears at low concentration. The genetic toxicology is also dependent on concentration, and the concentration of moxa smoke is essential. In clinical treatment, it is noted to control the level of moxa smoke, while the clinical safety standard of moxa smoke concentration is in need of further study.</p>
