【Abstract】Objective To study the surgical therapy and staging investigation about stage Ⅳ breast carcinoma. Methods The clinical data of 38 patients with stage Ⅳ breast carcinoma were summarized, and the patients were followed up. Results The stage Ⅳ patients who had isolated metastasis and removable primary tumor were treated by radical surgery with good effect. On the other hand, the stage Ⅳ patients who had extensive metastasis and primary tumor unresectable were treated by palliative operation with the living quality of patients becoming better and chemotherapy load cutting down. Conclusion The stage Ⅳ patients should be divided into stage Ⅳa and stage Ⅳb. And the stage Ⅳa patients should be treated by radical operation, and the stage Ⅳb by palliative operation.
ObjectiveTo explore the evaluation value of preoperative multislice spiral computed tomography angiography (MSCTA) for normative radical gastrectomy. MethodsThe anatomic distributions of celiac trunk and its three branches and their tributaries (common hepatic artery, right hepatic artery, left hepatic artery, splenic artery, and left gastric artery) of 86 patients with gastric cancer were comprehended by preoperative MSCTA, which were verified during the surgery. Simultaneously preoperative TNM staging was evaluated by MSCTA, which compared with postoperative pathological results. ResultsThe accuracy rate of preoperative MSCTA evaluating the distribution of celiac trunk and its three branches and their tributaries was 100%. Abnormal hepatic arteries were found in 22 cases by MSCTA, the mutation rate was 25.58%. Abnormal right hepatic arteries were found in 11 cases (12.79%), abnormal left hepatic arteries in 7 cases (8.14%), both abnormal right and left hepatic arteries in 1 case (1.16%), and abnormal common hepatic arteries in 3 cases (3.49%). Straight splenic arteries were found in 24 cases (27.91%), slightly curved splenic arteries in 44 cases (51.16%), and significantly curved splenic arteries in 18 cases (20.93%). Compared with postoperative pathological results, the accuracy rates of preoperative MSCTA evaluating gastric cancer T, N, and M staging were 75.58%（65/86）, 74.42%(64/86), and 91.86%(79/86), respectively. ConclusionsPreoperative MSCTA is an objective way to assess the distributions of celiac artery trunk and related tributaries of patients with gastric cancer. Also, it is an accurate method to evaluate the preoperative TNM stage of gastric cancer, which can help to make an individual operative plan and avoid the intraoperative injury of the artery.
ObjectiveTo detect the expression of Prox1 (prospero-related homeobox 1) gene in primary hepatocellular carcinoma (HCC), and to analyze the correlation of Prox1 gene expression with pathological grade and clinical stage of HCC. MethodsThe expressions of Prox1 gene in carcinoma tissues and adjacent cancerous tissues in HCC as well as normal liver tissues were detected by semi-quantitative RT-PCR, then the correlation of Prox1 gene expression with HCC pathological grade and clinical stage were analyzed. ResultsThe expression of Prox1 gene in carcinoma tissues (0.243±0.102) and adjacent cancerous liver tissues (0.537±0.235) was significantly lower than that in normal liver tissue (0.812±0.372), respectively （ Plt;0.01 or Plt;0.05）. Furthermore, the expression of Prox1 gene in carcinoma tissues was significantly lower than that adjacent cancerous liver tissues (Plt;0.05). The expressions of Prox1 gene in different pathological grade (F=97.950, Plt;0.001) and clinical stage were significantly different (F=228.300, Plt;0.001), and when compared with each other, the differences of pathological grade and clinical stage were also significant (Plt;0.001 or Plt;0.01). The expressions of Prox1 gene in HCC carcinoma tissue were negatively correlated with pathological grade (r=-0.930, Plt;0.01) and clinical stage (r=-0.980, Plt;0.01) of HCC. ConclusionsExpression of Prox1 gene may be related to the initiation and development of HCC, however, that whether Prox1 gene functions as tumor suppressor in HCC needs further investigation.
Objective To analyze the relationship between age and prognosis of colorectal patients in the database from colorectal cancer (DACCA). Methods The DACCA version selected for this data analysis was updated on January 5, 2022. The data items analyzed included age, sex, tumor site, tumor pathological nature, obstruction, pathological TNM (pTNM) stage, positive lymph node ratio, survival status and survival time. According to China’s age segmentation standard, the included data were grouped into younger group (<35 years old), middle-aged group (35–59 years old) and elderly group (>59 years old). Overall survival (OS) and disease specific survival (DFS) were analyzed in three age group, and OS and DSS in three age group were analyzed in pTNM stage stratification. Results Three thousand six hundred and twenty-five rows of data were obtained from DACCA database according to the screening conditions. The survival analysis results of different age groups show that: The middle-aged group had better OS compared with the elderly group at 1-year (97.4% vs. 96.0%, P=0.037), 3-year (90.9% vs. 88.0%, P=0.030) and 5-year (81.7% vs. 75.7%, P=0.002). Also, the middle-age group had better 5-year DSS (82.2% vs. 77.7%, P=0.020). There was no statistical difference in survival between the younger group and the elderly group (P>0.05). The survival analysis results of different age groups in each pTNM stage show that: ① The middle-aged group had better medium-term and long-term OS than the elderly group. In the pTNM Ⅰ stage, the 3- and 5-year OS in the middle-aged group were better than those in the elderly group (100% vs. 93.4%, P=0.004; 100% vs. 91.4%, P=0.005). In the pTNM Ⅱ stage, the 5- and 10-year OS in the middle-aged group were better than those in the elderly group (96.5% vs. 91.3%, P=0.018; 88.2% vs. 54.3%, P<0.001). In pTNM Ⅲ stage, 10-year OS in the middle-aged group was better than that in the elderly group (36.5% vs. 36.0%, P<0.001). In pTNM Ⅳ stage, the 5- and 10- year of OS in the middle-aged group were better than those in the elderly group (67.7% vs. 58.4%, P=0.016; 19.1% vs. 7.2%, P=0.049). ② The middle-aged group had better medium-term and long-term DSS than the elderly group. In the pTNM Ⅰ stage, the 3- and 5- year DSS in the middle-aged group wrer better compared to the elderly group (100% vs. 96.9%, P=0.047; 100% vs. 94.9%, P=0.049). In the pTNM Ⅱ stage, the 10-year DSS in the middle-aged group outperformed that in the elderly group (88.2% vs. 61.9%, P=0.002). In the pTNM Ⅳ stage, the 5- and 10-year DSS in the middle-aged group were better than the elderly group (68.3% vs. 59.1%, P=0.020; 20.9% vs. 7.7%, P=0.040). ③ Except pTNM I stage, there was no significant difference in survival of other pTNM stages between young group and old group (P>0.05). In the pTNM Ⅰ stage, 3- and 5- year OS were better in the younger group compared with the elderly group (100% vs. 93.4%, P=0.004; 100% vs. 91.4%, P=0.005), and better 3- and 5- year DSS in the younger group (100% vs. 96.9%, P=0.047; 100% vs. 94.9%, P=0.049). Conclusions The age of colorectal cancer patients may have an impact on long-term survival. Middle-aged patients have better prognosis compared with elderly patients, and the younger group patients have better prognosis in pTNM stage Ⅰ only.
ObjectiveTo analyze the relation between the literacy and prognosis in the patients with colorectal cancer (CRC) in the current version of the Database from Colorectal Cancer of West China (DACCA). MethodsThe version of DACCA selected for this data analysis was updated on September 12, 2022. The data items analyzed included age, gender, literacy, tumour site, nature of tumour, pathological TNM (pTNM) stage, survival status, and survival time. The overall survival and disease-specific survival of the CRC patients with different literacy (illiteracy, primary, secondary, and tertiary educations) after radical resection were compared, and then which were analyzed in the patients with different pTNM stages. ResultsA total of 3 692 data eligible for the study were screened, of which 202 were illiteracy, 1 054 were primary education, 1 809 were secondary education, and 627 were tertiary education; And there were 13 of stage 0, 406 of stage Ⅰ, 1 193 of stage Ⅱ, 1 139 of stage Ⅲ, and 941 of stage Ⅳ. The differences in the comparison of the pTNM stage and the nature of the tumour among the patients with the four levels of literacy were not statistically significant (P>0.05), while the differences in the comparison of the gender, age, and tumour site were statistically significant (P<0.001). The overall survival and disease-specific survival curves of the CRC patients with different literacy had no statistical differences (χ2=1.982, P=0.576; χ2=2.618, P=0.454), and the stratified overall survival curves had no statistical differences among the patients with pTNM stages Ⅰ to Ⅳ (stage Ⅰ: χ2=1.361, P=0.715; stage Ⅱ: χ2=3.507, P=0.320; stage Ⅲ: χ2=3.144, P=0.370; stage Ⅳ: χ2=4.993, P=0.172), and the stratified disease-specific survival curves had no statistical differences (stage Ⅰ: χ2=0.723, P=0.868; stage Ⅱ: χ2=3.295, P=0.348; stage Ⅲ: χ2=4.767, P=0.190; stage Ⅳ: χ2=6.177, P=0.103). ConclusionsThe results of this study based on real-world big data analysis suggests that the differences of overall survival and disease-specific survival of CRC patients with different literacy levels (illiterate, primary, secondary, and tertiary education) are not statistically significant, and the results of stratified analysis based on pTNM staging are consistent with this. In the future, limitations of this study can be excluded and further analysis can be conducted by combining treatment details or expanding sample data to seek more realistic results.
【Abstract】Objective To evaluate the value of pTNM classification in predicting the prognosis of hepatic cell carcinoma after liver transplantation. Methods Fifty-nine HCC cases undergoing liver transplantation between April 1993 and January 2003 were retrospectively reviewed. Fiftynine cases were staged by using the pTNM classification. Results The 1-year survival rates were 66.67%, 66.67%, 40.91% and 31.75% for Ⅰ，Ⅱ，Ⅲa and Ⅳa stages，2-year survival rates were 66.67%, 66.67%, 21.29% and 31.75%, the difference was not statistically significant. Conclusion The pTNM classification is not good enough to predict the prognosis of hepatic cell carcinoma after liver transplantation.
Objective To investigate the accuracy of preoperative high-resolution magnetic resonance imaging (MRI) scans to predict tumor stage, lymph node stage, and circumferential resection margin (CRM) involvement. Methods Between September 2006 and May 2009, 42 patients with histologically proven rectal cancer by the colonoscopic biopsy in Peking Union Medical College Hospital were staged preoperatively using MRI. All of the patients underwent total mesorectum excision (TME) operation within 1 week after MRI examination. The specimens were reported according to the 2002 TNM staging system for primary colorectal cancer of the American Joint Committee on Cancer (AJCC). Concordance between radiologic staging of tumor, local lymph node, and CRM involvement and pathologic reporting was assessed by means of the Kappa statistic.Results For all of 42 patients, MRI correctly staged the tumor in 36 patients, understaged in 3 patients and overstaged in 3 patients. Statistically, there was a better correlation between pathologic and radiologic tumor staging (Kappa=0.731, P=0.000). MRI correctly staged lymph node status in 31 patients, understaged in 5 patients and overstaged in 6 patients. Statistically, there was a common correlation between pathologic and radiologic lymph node staging (Kappa=0.410, P=0.009). MRI correctly reported the status of the CRM in 40 patients. Statistically, there was the best correlation between pathologic and radiologic reporting of CRM involvement (Kappa=0.829, P=0.000). Conclusion Preoperative highresolution MRI scans has a good concordance with pathologic tumor stage but common with pathologic lymph node stage. Preoperative highresolution MRI can provide reliable information about CRM and thus help to choose which patient could benefit from the preoperative neoadjuvant therapy.
The TNM staging of lung cancer which is now widely used in clinic was formally proposed in 1997. It has played quite an important role in directing the diagnosis and treatment of lung cancer as well as the clinical research in the past decade. However, at the same time, there are some insufficiencies which are emerging gradually. By collecting the clinical information from 100 869 patients, in 2007, International Association for the Study of Lung Cancer(IASLC) made a deep analysis on the relativity between TNM staging and prognosis, and put forward the suggestions to revise the Seventh Edition of the TNM staging of lung cancer: (1) According to the size of tumor, the primary T staging is divide into T1a (the maximum tumor diameter≤2 cm), T1b (3 cm≥the maximum tumor diameter＞2 cm), T2a (5 cm≥the maximum tumor diameter＞3 cm) and T2b (7 cm≥the maximum tumor diameter＞5 cm); (2) T 2c (the maximum tumor diameter gt;7 cm) and additional nodules in the same lobe are classified as T3, while nodules in the ipsilateral nonprimary lobe are classified as T4;(3) Cancerous hydrothorax, pericardial effusion and the additional nodules in the contralateral lung are classified as M1a, while the extrapulmonary metastases are classified as M1b. It is believed that the new revised edition will has higher international authority and identification degree, and it will play a more meticulous and accurate guiding role in the treatment of lung cancer and its predicting prognosis in the future. At the same time, it will provide a new starting point to the research of lung cancer.
