Objective To study the relationship between metalloproteinases (MMPs) and breast cancer. Methods The literature in recent years on the relationship between the expression of MMPs and breast cancer was reviewed. Results The balance between MMPs and tissue inhibitors of metalloproteinases (TIMPs) is keeping normally kept in human body. Many of the studies showed that the expression of MMPs is increased in breast cancer. Conclusion The growth, invasion and metastasis of breast cancer is closely related with the increased expression of MMPs. This suggests that MMPs is a valuable prognostic marker and TIMPs would be a novel drug against cancer.
ObjectiveTo analyze the follow-up data of colorectal cancer in the Database from Colorectal Cancer (DACCA).MethodsThe information in the Dacca database was screened, and the one whose operative date and follow-up date were not blank in the total data was selected. The follow-up data were analyzed, including length of follow-up, survival outcomes, coping styles (doctors’ attitude and reaction for follow-up), follow-up path (whether to choose out-patient, Wechat, QQ tools, phone call, text message, mobile application, face-to-face), the number of follow-up (the number of out-patient follow-up, the number of telephone follow-up, and the number of follow-up within 5 years).ResultsA total of 6 437 data items were analyzed for colorectal cancer adjuvant follow-up. ① The follow-up period of five years (2004–2015) was 56.6% (3 642/6 437), and the follow-up time was 0–201, 67 (26, 97) months. ② The highest data composition ratio of survival outcomes was “Survival” (79.7%, 4 611/5 787), and in the data with five-year follow-up period (2004–2015), the highest data composition ratio of survival outcomes was “Survival” (75.0%, 2 550/3 401), and the survival rate of the five-year follow-up period in 2008 was the highest (91.4%, 235/257). ③ The highest data composition ratio of the coping styles was the doctors’ active follow-up (76.8%, 2 121/2 762). ④ The highest data composition ratio of the follow-up path was out-patient service (90.6%, 4 236/4 676). ⑤ The highest data composition ratio of the number of out-patient follow-up was conducted by the original surgical team (100%, 4 380/4 380), the specific number was 0–130、5 (2, 10) times. The data composition ratio of telephone follow-up was 86.9% (3 808/4 380) and the specific number was 0–68、0 (0, 1) times. The highest frequency of follow-up was in the first year (89.9%, 3 044/3 386) and the specific number was 0–73、5 (3, 9) times.ConclusionBy expounding the characteristics of the colorectal cancer follow-up from colorectal cancer in DACCA, it provides some references for using big data to determine prognosis.

ObjectiveTo explore the expression of collagen Ⅳ in breast cancer and its clinical significance. We analyzed the correlation of the results with other prognostic parameters which included tumor size, status of estrogen receptor, axillary nodal status, TNM grade, and 5 years survival. The expression of collagen Ⅳ in 93 cases of human primary breast cancer as well as 5 cases of benign breast masses were examined.MethodsUsing monoclonal antibodies of collagen Ⅳ, the expression of collagen Ⅳ in breast masses were detected with immunohistochemical technique (LSAB).ResultsThe absent expression of collagen Ⅳ in the tumor masses was correlated with axillary lymph node involvement, tumor size and poor prognosis (5 years survival). The patients who had no expression of collagen Ⅳ in tumor masses had a shorter survival. ConclusionThe expression of collagen Ⅳ in tumor samples are correlated with axillary node involvement and prognosis. Collagen Ⅳ would be helpful for evaluation of invasion and treatment in breast carcinoma.
ObjectiveTo unscramble personal data and its tags and structures of Database from Colorectal Cancer (DACCA) in West China Hospital.MethodThe way of words for description was used.ResultsThe definition and setting of 23 items with 18 categories for the personal data from DACCA in West China Hospital was performed. The relevant data label of each item and the structured way needed at the big data application stage were elaborated and the corrective precautions of classification items were described. The three classification items involved privacy attention were described in detailed.ConclusionsBased on description about personal data from DACCA in West China Hospital, it is provided a clinical standard and guide for analyzing of DACCA in future. It also could provide enough experience for construction of colorectal cancer database by staff from same occupation.
ObjectiveTo summarize research progress of comprehensive treatment based on gene therapy, immunotherapy, and targeted therapy in recent years in order to improve understanding and treatment level of triple negative breast cancer (TNBC).MethodThe literatures about TNBC treatment in recent 5 years were reviewed and summarized.ResultsTNBC was more invasive than other types of breast cancer due to its lack of targeted receptors, and its recurrence and metastasis were earlier. The treatment plan was still mainly surgical treatment, supplemented by the chemotherapy and radiotherapy.ConclusionsAlthough recent studies of TNBC in surgical treatment, chemoradiotherapy, targeted therapy and other aspects have shown a good clinical application prospect, more evidences of clinical trials with large samples are still needed. With the deepening of molecular mechanism research, endocrine therapy and targeted drug therapy, including androgen-receptor-positive, have provided some new ideas for treatment of TNBC.

ObjectiveTo understand the status of application of Colorectal Cancer Predicted Risk Online (CRC-PRO) in colorectal cancer screening, and to analyze the possible practical value in our country.MethodsThe research literatures on the colorectal cancer risk prediction tool of CRC-PRO at home and abroad were searched. The overview and application status of this tool were reviewed.ResultsCRC-PRO could predict the 10-year risk rate of individuals developing colorectal cancer. It could quickly provide clinicians with accurate estimates of patient risk to help clinicians and patients identify screening programs and improve prevention strategies.ConclusionsCRC-PRO can not only give specific probability of risk, but also easy to operate. But based on regional differences, in the promotion of CRC-PRO, it is necessary to carry out multi-center research in more diverse populations for more extensive clinical analysis and verification, to further expand the scope of application of this tool.
ObjectiveBased on the current version of Database from Colorectal Cancer (DACCA), we aimed to analyze the comorbidities and preoperative physical status of colorectal cancer patients.MethodsThe DACCA version selected for this data analysis was updated on May 9, 2019. The data items included: surgical comorbidities and classified by systems, surgical history, pelvic disease history, medical comorbidities, and some important subdivision types, infectious disease status, allergic history, nutrition risk screening 2002 (NRS2002) score, amount of weight loss after illness, anemia, low protein status, preoperative ascites status, preoperative pleural effusion status, immune system disease and immunocompromised status, and preoperative nutritional support. Characteristic analysis was performed on each selected data item.ResultsA total of 6 166 admitted data were filtered from the DACCA database. Among them, surgical comorbidities, surgical history, medical comorbidities, and allergy history had 6 166 admitted data, and weight loss had admitted 4 703. There were 2 923 (47.4%) with surgical comorbidities. According to the system, the most common one was digestive system (2 005, 68.6%), and the least one was skin tissue system (24, 0.8%). There were 4 361 (70.7%) patients without surgical history and 1 805 (29.3%) patients had surgical history. There were 2 397 (38.9%) patients without medical comorbidities and 3 769 (61.1%) had medical comorbidities, of which pneumonia/pulmonary infection/chronic bronchopneumonia/lung indeterminate nodules were the most common(2 330, 37.8%), the least was cerebral infarction (unspecified type, 63, 1.0%). There were 5 813 (94.3%) without allergy history and 353 (5.7%) had allergy history. According to the NRS2002 nutrition screening criteria, the scores ranged from 1 to 7 points, with an average of 1.22 points, which could be classified as non-nutrition risk (5 279, 85.6%, included 1 point of 4 310, 2 points of 969), nutritional risk (887, 14.4%, included 3 points of 415, 4 points of 358, 5 points of 100, 6 points of 12, and 7 points of 2), the result of linear regression analysis of NRS2002 scores with the trend of the year showed that: ŷ=0.000 2x–6.275 8, R2=0.716 2, P<0.001. A total of 2 840 (60.4%) had no weight loss while 1 863 (39.6%) had, and weight loss with the trend of year were analyzed by linear regression analysis: ŷ=0.000 2x–3.956, R2=0.685 7, P<0.001. The number of cases of other physical status and the proportion of valid data were anemia (1 194, 33.1%), preoperative ascites (1829, 51.7%), preoperative pleural effusion (171, 5.7%), hypoproteinemia (1 206, 33.6%), immune system disease and immunocompromised status (495, 56.6%), and nutritional support (824, 25.0%).ConclusionsThrough the analysis of the DACCA database, nearly 1/2 of colorectal cancer surgery patients have surgical comorbidities before surgery, more than 1/2 of the patients have medical comorbidities, and the types of diseases are various. Preoperative nutritional status in patients with colorectal cancer also shows certain characteristics, suggesting the state of preoperative risk. These data will provide a detailed big data basis for future preoperative risk assessment of colorectal cancer.
