The announcement of the 9th edition of TNM staging system for thymic tumors was one of the highlights at the World Conference on Lung Cancer 2023. The revision, based on a larger and more detailed database, provides changes and confirmation from the last system. The 9th edition of TNM staging system aims to balance statistical significance and clinical feasibility. The birth of an improved TNM staging system heralds the changes that will follow in clinical practice and scientific research.
In this report, 1175 cases of resected gastric cancer were staged, followed up and statistincally calculated by using the international unifying new TNM staging system for gastric cancer. The prognostic value of the TNM staging system was also tested with relevant statistics. The results showed that:(1)the 5-year survival rates of Ⅰa、Ⅰb、Ⅱ、Ⅲa、Ⅲb and Ⅳ were 100%,84%,65%,43%,25% and 13% respectively; (2)The 5-year survival rates of the subgroups withing same stage were quite; (3)the analysys of correlation and regression between the new staging and the prognosis provided that correlation coefficient r equals to -0.990(Ｐ＜0.005), and regression coefficient b equals to -0.1345(Ｐ＜0.005). These results indicate that there is statistical identity beween the new TNM staging for gastric cancer and the prognosis, and certify the rationality for the new staging in application and its accuracy to reflect the prognosis.
Objective To improve esophageal lymph node staging and investgate an ideal esophageal lymph node metastasis staging method. Methods The clinical pathological data and followup data of the 236patients who had undergone thoracic esophagectomy with at least 6 lymph nodes (LN) removed from January 1985 to December 1989 were analyzed retrospectively. Cox proportional hazard model was used to screen risk factors, and Logrank test was applied to perform survival analysis according to lymph node metastasis staging (number, distance and extent). Results The 10-year follow-up rate was 92.3%（218/236）. The overall 1-year, 5-year and 10-year survival rates were 80.2%, 43.1% and 34.2% respectively. One hundred and twelve (47.4%) patients had LN metastasis, and their 5-year survival rates were lower than that of patients without LN metastasis (14.8% vs. 66.6%; χ2=77.18, P=0.000). Cox regression analysis showed that besides depth of invasion, differentiation grade and LN metastasis, the number, distance and extent of LN metastasis were the independent risk factors which could influence prognosis. A further analysis was given via univariate Logrank test. When grouped according to the number of LN metastasis, there were significant differences in overall survival rates (χ2=96.00,P=0.000), but no significant difference was found in survival rates between N2 and N3 group(Pgt;0.05). When grouped according to the distance of LN metastasis, there were significant differences in overall survival rates (χ2=79.29, P=0.000), but no significant difference was found in survival rates among S1, S2 and S3 group(Pgt;0.05). When grouped according to the extent of LN metastasis (0, 1, and ≥2 fields), there were significant differences in overall survival rates (χ2=87.47, P=0.000), and so were the survival rates among groups (χ2=5.14, P=0.023). Conclusion Revising the current Nclassification of TNM staging of esophageal cancer according to the extent of LN metastasis(0, 1, and ≥2 fields) is more reasonable, and can reflect the prognosis of patients with esophageal cancer after esophagectomy better.

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.
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.
【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.
Lung cancer management is complex and requires a multi-disciplinary approach to provide comprehensive care. Interventional pulmonology (IP) is an evolving field that utilizes minimally invasive modalities for the initial diagnosis and staging of suspected lung cancers. Endobronchial ultrasound guided sampling of mediastinal lymph nodes for staging and detection of driver mutations is instrumental for prognosis and treatment of early and later stage lung cancers. Advances in navigational bronchoscopy allow for histological sampling of suspicious peripheral lesions with minimal complication rates, as well as assisting with fiducial marker placements for stereotactic radiation therapy. Furthermore, IP can also offer palliation for inoperable cancers and those with late stage diseases. As the trend towards early lung cancer detection with low dose computed tomography is developing, it is paramount for the pulmonary physician with expertise in lung nodule management, minimally invasive sampling and staging to integrate into the paradigm of multi-specialty care.
ObjectiveTo explore the value of multi-slice spiral CT (MSCT) in ycT stage and ycN stage evaluation of patients with locally advanced gastric cancer (cT4bN0-3M0) who underwent surgery after transformation therapy.MethodsClinical data of 32 patients with locally advanced gastric cancer (cT4bN0-3M0) in Affiliated Yantai Yuhuangding Hospital of Qingdao University form January 2017 to April 2019 were retrospective analyzed. All the patients underwent surgery after SOX regimen transformation therapy. Preoperative MSCT plain and enhanced scan were used to evaluate clinical T stage (ycT) and clinical N stage (ycN). The accuracy of MSCT scanning was evaluated by comparing with the gold standard for postoperative pathological ypT stage and ypN stage.ResultsThe accuracy of preoperative MSCT examination on ycT stage after transformation therapy was 78.1% (25/32), and that of ycN was 56.3% (18/32).ConclusionThe accuracy of MSCT in preoperative ycT stage and ycN stage after successful transformation therapy for locally advanced gastric cancer (cT4bN0-3M0) is relatively high.
【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.
