In 2025, the American Cancer Society published "Cancer statistics, 2025", which projected cancer data for the upcoming year based on incidence data collected by central cancer registries (through 2021) and mortality data obtained from the National Center for Health Statistics (through 2022). Similarly, the National Cancer Center of China released "Cancer incidence and mortality in China, 2022" in December 2024, analyzing data from 22 cancer registries across the country. This study provides a comparative analysis of cancer incidence and mortality trends in China and the United States during the same period, with a focus on sex- and age-specific distributions and long-term changes in cancer patterns. Long-term trends indicate that lung and liver cancer mortality rates in China have declined, primarily due to tobacco control measures and hepatitis B vaccination programs. However, the burden of gastric and esophageal cancers remains substantial. In the United States, mortality rates for colorectal and lung cancers have continued to decline, largely attributed to widespread screening programs and advances in immunotherapy. As economic growth and social development, China’s cancer profile is gradually shifting towards patterns observed in countries with high human development index. However, the prevention and control of upper gastrointestinal cancers remains a critical public health challenge that requires further attention.
ObjectiveTo evaluate the therapeutic effect of liver transplantation (LT) combined with adenovirus-mediated delivery of herpes simplex virus thymidine kinase / ganciclovir (ADV-TK/GCV) in treatment of patients with hepatocellular carcinoma (HCC), so as to benefit more patients with HCC beyond the Milan criteria. MethodsThe clinicopathologic data of patients with HCC underwent LT by the author team since 2007 were collected and analyzed. The patients were assigned into simple LT group and LT+ADV-TK/GCV group. The 5-year cumulative overall survival rate and relapse free survival rate of all LT patients and the patients with LT beyond the Milan criteria by simple LT and LT+ADV-TK/GCV therapy were compared. Meanwhile, Cox regression was used to analyze the risk factors affecting long-term overall survival rate and relapse free survival rate of all patients with HCC after LT. ResultsA total of 216 patients eligible for inclusion were collected in this study, including 134 patients in the simple LT group and 82 patients in the LT+ADV-TK/GCV group, 162 of whom beyond the Milan criteria, including 101 patients underwent the simple LT and 61 patients underwent the LT+ADV-TK/GCV. There were no statistical differences in the baseline data between the simple LT and LT+ADV-TK/GCV in all patients and patients beyond the Milan criteria (P>0.05). There were no statistical differences in 5-year overall survival rate and relapse free survival rate of all patients with HCC (P>0.05). The 5-year cumulative overall survival rate of the LT+ADV-TK/GCV group was better than that of the simple LT group in the patients beyond the Milan criteria (χ2=4.11, P=0.047), but it was not found that the 5-year cumulative relapse free survival rate had statistical difference (27-month survival time as the critical value, P=0.46, P=0.06). Cox regression multivariate analysis results showed that the larger cumulative tumor diameter, the preoperative elevated serum alpha fetoprotein (>400 μg/L), later TNM stage, and without combination of ADV-TK/GCV therapy increased the probability of shorter overall survival of patients after LT; and the patient’s older age, the larger cumulative tumor diameter, and later TNM stage increased the probability of shorter relapse free survival after LT, and it was not found that the combination of ADV-TK/GCV therapy had an impact on the relapse free survival. ConclusionLT combined with ADV-TK/GCV therapy can obviously improve overall survival among patients beyond the Milan criteria, more patients with advanced HCC will be candidates for LT combined with ADV-TK/GCV therapy.
Objective To investigate the relative factors on tumor reocurrance or matastasis for over five years survival patients after esophageal carcinoma resection. Method We followed up the patients underwent esophageal carcinoma resection in our hospital and discharged between October 1997 and October 2002. We analyzed the clinical data of 181 over five years survival patients with complete follow-up data. There were 148 males and 33 females with the mean age of 63.9 years ranging from 60-70 years. We summarized the follow-up data and carried on the univariate analysis of relatively recurrent data. Result The result of univariate analysis showed that tumor recurrence as well as matastasis statistically related with degree of differentiation, pTNM stage, whether there was lymph node metastasis or not, and the number of lymph node metastasis (P<0.05), but not with gender, age, the length of tumor, the site of tunor, or other clinicopathologic characteristics (P>0.05). Conclusion The main factors influencing over five years survival rate after esophageal carcinoma resection are pTNM staging when operating, lymph node metastasis or not, and the number of lymph node metastasis.
ObjectiveTo review and analyze the long-term results of delayed repair of median nerve injury. MethodsBetween January 2004 and December 2008, 228 patients with median nerve injury undergoing delayed repair were followed up for more than 4 years, and the clinical data were retrospectively analyzed. There were 176 males (77.19%) and 52 females (22.81%), aged 2-71 years (median, 29 years). The main injury reason was cutting injury in 159 cases (69.74%);203 cases had open injury (89.04%). According to the injury level, injury located at area I (upper arm) in 38 cases (16.67%), at area II (elbow and proximal forearm) in 53 cases (23.25%), at area III (anterior interosseous nerve) in 13 cases (5.70%), and at area IV (distal forearm to wrist) in 124 cases (54.39%). The delayed operations included delayed suture (50 cases, 21.93%), nerve release (149 cases, 65.35%), and nerve graft (29 cases, 12.72%). ResultsFor patients with injury at area I and area II, the results were good in 23 cases (25.27%), fair in 56 cases (61.54%), and poor in 12 cases (13.18%) according to modified Birch and Raji’s median nerve grading system;there was significant difference in the results between 3 repair methods for injury at area II (χ2=6.228, P=0.044), but no significant difference was found for injury at area I (χ2=2.241, P=0.326). Twelve patients (13.18%) needed musculus flexor functional reconstruction. Recovery of thenar muscle was poor in all patients, but only 5 cases (5.49%) received reconstruction. Thirteen cases of nerve injury at area III had good results, regardless of the repair methods. For patients with injury at area IV, the results were excellent in 6 cases (4.84%), good in 22 cases (17.74%), fair in 72 cases (58.06%), and poor in 24 cases (19.35%) according to Birch and Raji’s grading system;there was significant difference in the results between 3 repair methods (χ2=12.646, P=0.002), and the result of delayed repair was better. ConclusionThe results of delayed repair is poor for all median nerve injuries, especially for high level injury. The technique of repair methods vary with injury level. For some delayed median nerve injuries, early nerve transfer may be a better choice for indicative patients.
ObjectiveTo explore the influence of evidence-based nursing care of catheterization on the incidence of urinary tract injury and urinary tract infection in patients with spinal cord injury and long-term indwelling catheters.MethodsFrom July 1st, 2017 to November 30th, 2018, 100 patients with spinal cord injury indwelling catheters in Department of Spinal Surgery were prospectively selected as the research objects. According to the admission time, patients admitted between July 2017 and February 2018 were assigned into the control group (n=50), and patients admitted between March 2018 and November 2018 were assigned into the observation group (n=50). Traditional catheter placement was used in the control group, while evidence-based catheter placement was used in the observation group. The incidences of catheter-related urethral injury and urinary tract infection after the catheterization were compared between the two groups.ResultsThere was no statistically significant difference in gender, age, diagnosis, or length of hospital stay between the two groups (P>0.05). Catheter placement was performed 57 times in the control group and 59 times in the observation group during hospitalization. After catheterization, the incidences of urethral hemorrhage and gross hematuria in the control group [22.80% (13/57) and 15.78% (9/57), respectively] were higher than those in the observation group [both were 1.69% (1/59)], with statistical differences between the two groups (P<0.05). The incidence of urinary tract infection in the control group differed from that in the observation group [42.0% (21/50) vs. 18.0% (9/50), P=0.009].ConclusionThe evidence-based urinary catheterization method for patients with spinal cord injury and long-term indwelling catheter can effectively prevent catheter-related urinary tract injury, reduce the incidence of catheter-related urinary tract infection during hospitalization, and improve the quality of clinical care.
ObjectiveBased on the latest version of the Database from Colorectal Cancer(DACCA), this study analyzed the long-term effect of neoadjuvant therapy combined with intersphincteric resection (ISR) in patients with rectal cancer. MethodsAccording to the established screening criteria, clinical data of 944 patients with rectal cancer admitted from January 2009 to December 2020 were collected from the DACCA updated on March 21, 2022, to explore the influencing factors for overall survival (OS) and disease specific survival (DSS) of rectal cancer treated with neoadjuvant therapy combined with ISR, by Cox proportional hazard regression model. Results① The 3-year OS and DSS survival rates of neoadjuvant therapy combined with ISR for rectal cancer were 89.2% and 90.4%, respectively, and the 5-year OS and DSS survival rates were 83.9% and 85.4%, respectively. ② For different ISR surgical methods and neoadjuvant therapy plans, there were no significant differences in OS and DSS (P>0.05), but there were significant differences in OS and DSS among different ypTNM stage groups (P<0.001), patients with ypTNM 0–Ⅱ had better OS and DSS. ③ BMI, ypTNM stage and R0 resection were influencing factors for OS and DSS (P<0.05). ④ The overall incidence of postoperative complications was low, including 6.4% (60/944) within 30 days, 7.5% (71/944) within half a year and 3.3% (31/944) over half a year after operation. ConclusionsIn the comprehensive treatment of patients with low/ultra-low rectal cancer, neoadjuvant therapy combined with ISR can achieve relatively stable and good long-term oncological efficacy, and the incidence of short-term postoperative complications is not high, which is one of the options.
Aiming at the shortcomings in the theory and practice of integrated elderly care and medical services in China, using the methods of literature analysis and comparative analysis, we summarize four typical models of integrated elderly care and medical services, namely, the American commercial pension model, the British national tax financing system pension model, the Japanese national security transformation, and the German long-term care insurance system, and compare the four models systematically from the aspects of system overview, service principle, operation mode, financing supervision, etc. The enlightenment for the policy and practice development of integrated elderly care and medical services in China is obtained: firstly, the service concept should be innovated; secondly, it is important to improve the relevant legal protection and supporting measures; thirdly, the refinement of the integrated elderly care and medical service projects are supposed to be promoted; fourthly, a multi-party linkage mechanism ought to be establishd; and fifthly, community endowment model should be advocated.
ObjectiveTo evaluate the medium-and long-term effectiveness of the 3rd-generation ceramic-on-ceramic total hip arthroplasty (THA) for end-stage hip disease. MethodsA retrospective analysis was made on the clinical data of 142 patients (148 hips) who underwent the 3rd-generation ceramic-on-ceramic THA between May 2001 and May 2005. There were 78 males and 64 females, aged 57.2 years on average (range, 23-81 years). Preoperative diagnosis was avascular necrosis of femoral head in 73 patients (77 hips), degenerative osteoarthritis in 35 patients (36 hips), femoral neck fracture in 18 patients (18 hips), rheumatoid arthritis in 14 patients (15 hips), and septic hip sequelae in 2 patients (2 hips). The preoperative Harris hip score was 58.3±12.9. ResultsAll incisions healed by first intention without complication. All patients were followed up 8.8 years on average (range, 7-12 years). At the last follow-up, the Harris hip score (92.5±10.2) was significantly higher than that at pre-operation (t=-25.29, P=0.00). At the last follow-up, there were 4 hips with groin pain, 6 hips with thigh pain. Complications occurred in 6 cases (6 hips), including loosening cups in 2 hips, hip dislocation in 2 hips, ceramic head fracture in 1 hip, and squeaking in 1 hip. The revision rate was 1.35% (3/148). X-ray film showed that acetabular cup loosening in 2 hips, discontinuous radiolucent line in 4 hips, and new bone formation in 88 hips; discontinuous radiolucent line around femoral component was observed in 25 hips, endosteal new bone formation in 95 hips, cortical bone hypertrophy in 2 hips, and femoral component subsidence in 9 hips (less than 2 mm). ConclusionThird-generation ceramic-on-ceramic THA is an effective treatment for end-stage hip disease, and can achieve satisfactory medium-and long-term effectiveness and a high implant survival rate.
