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.
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 understand the relation between the occupation and long-term prognosis of the patients with colorectal cancer (CRC) based on the Database from Colorectal Cancer (DACCA). MethodsThe selected updated DACCA database as of June 29, 2022 was used for this study. The included patients were assigned into intellectual occupations group (intellectual group) and manual occupations group (manual group) referring to relevant regulatory documents in China. The survival status of the intellectual group and the manual group was compared, and then were stratified by pTNM stage. ResultsA total of 1 974 patients were included from the DACCA database according to the selection criteria, 349 of whom in the intellectual group and 1 625 of whom in the manual group. The intellectual group had higher 5-year cumulative overall survival rate (92.1% vs. 84.5%, P<0.001) and disease-specific survival rate (92.1% vs. 85.8%, P=0.002), as well as higher 10-year cumulative overall survival rate (72.4% vs. 55.2%, P<0.001) and disease-specific survival rate (75.4% vs. 59.1%, P<0.001) compared to the manual group. The stratified analysis by pTNM stage found that, for the patients with pTNM Ⅲ stage, the 5- and 10-year cumulative overall survival rates of the intellectual group were higher than those of the manual group (94.0% vs. 82.3%, P<0.001; 67.1% vs. 43.7%, P=0.014), simultaneous the 5- and 10-year cumulative disease-specific survival rates were the same as the overall survival rate (94.0% vs. 83.5%, P=0.001; 69.5% vs. 47.9%, P=0.026). Furthermore for the the patients with pTNM Ⅱ stage , it was found that the the 10-year cumulative disease-specific survival rate of the intellectual group was higher than that of the manual group (93.5% vs. 78.7%, P=0.009).ConclusionsFrom the analysis results of this study, occupation might be related to long-term prognosis in CRC cancer patients. A general trend is that the long-term prognosis of patients with intellectual occupations might be better than that of patients with manual occupations, and this difference might be relatively marked in the patients with pTNM Ⅱ and Ⅲ stages, but it needs to be autious and objective.

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.

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.
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.
Breast cancer is one of the most common malignant tumors in women, and its treatment and management strategies are crucial for improving patients’ prognosis and quality of life. Early breast cancer refers to lesions confined to the breast and regional lymph nodes (N1 stage) without distant metastasis. Thanks to the improvement of screening techniques, the detection rate of early breast cancer has increased. The “early diagnosis and early treatment” model has led to a decrease in breast cancer mortality, especially among young women. The 2024 European Society for Medical Oncology (ESMO) clinical practice guideline for the diagnosis, treatment, and follow-up of early breast cancer aims to provide comprehensive and standardized recommendations for the diagnosis and treatment of early breast cancer, helping clinicians make optimal decisions. This article interprets the main content of the guideline in order to provide references and assistance for the current clinical diagnosis and treatment of early breast cancer in China.
