ObjectiveTo analyze the relationship between occupational type of patients with colorectal cancer (CRC) and decision-making and curative effect of neoadjuvant therapy in the current version of the Database from Colorectal Cancer (DACCA). MethodsThe eligible CRC patients were collected from June 29, 2022 updated DACCA according to the screening criteria, in which the data items analyzed included: gender, age, BMI, blood type, marriage, occupation, neoadjuvant therapy, symptomatic changes, imaging changes, and tumor regression grade (TRG), and the occupations were classified into the mental labour group, physical labour group, and the unemployed and resident groups according to the type of labour, then compared the decision-making and curative effect of neoadjuvant therapy among the 3 groups. ResultsA total of 2 415 eligible data were screened, of which 1 160 (48.0%) were the most in the manual labour group, followed by 877 (36.3%) in the unemployed and resident group, and finally 378 (15.7%) in the mental labour group. The proportion of those who did not use targeted drugs was higher in both patients ≤60 years old and >60 years old [75.6% (958/1 267) vs. 82.5% (947/1 148)], with both differences being statistically significant (P=0.004 and P=0.019), and among patients >60 years old, the different occupational types were associated with symptomatic changes and imaging changes after neoadjuvant therapy, with the highest number of both changes to partial remission [71.5% (161/225) vs. 66.7% (148/222)], both differences being statistically significant (P=0.001 and P=0.017). ConclusionThe analysis results of DACCA data reveal that the occupational type of CRC patients was associated with the choice of neoadjuvant therapy, and that different occupational types were associated with changes in curative effect before and after neoadjuvant therapy in CRC patients >60 years old, which needs to be further analysis for the reasons.
Objective To investigate the perioperative differences between video-assisted thoracoscopic surgery (VATS) and thoracotomy after neoadjuvant therapy in patients with non-small cell lung cancer (NSCLC). Methods Clinical data of NSCLC patients who underwent VATS or thoracotomy after neoadjuvant therapy at Shanghai Pulmonary Hospital from June 2020 to May 2022 were retrospectively collected. Perioperative outcomes were compared between the two groups. Results A total of 260 patients were enrolled, 184 (70.8%) patients underwent VATS and 76 (29.2%) patients underwent thoracotomy. After propensity matching, there were 113 (62.4%) patients in the VATS group and 68 (37.6%) patients in the thoracotomy group. VATS had similar lymph node dissection ability and postoperative complication rate with thoracotomy (P>0.05), with the advantage of having shorter operative time (146.00 min vs. 165.00 min, P=0.006), less intraoperative blood loss (50.00 mL vs. 100.00 mL, P<0.001), lower intraoperative blood transfusion rate (0.0% vs. 7.4%, P=0.003), less 3-day postoperative drainage (250.00 mL vs. 350.00 mL, P=0.011; 180.00 mL vs. 250.00 mL, P=0.002; 150.00 mL vs. 235.00 mL, P<0.001), and shorter postoperative drainage time (9.34 d vs. 13.84 d, P<0.001) and postoperative hospitalization time (6.19 d vs. 7.94 d, P=0.006). Conclusion VATS after neoadjuvant therapy for NSCLC is safer than thoracotomy and results in better postoperative recovery.
Objective To formulate an evidence-based adjuvant therapeutic plan for a patient with large area pressure ulcers. Methods Based on an adequate assessment of the patient’s condition and using the principle of PICO, we searched The Cochrane Library (Issue 1, 2008), DARE (Issue 3, 2008), CCRT (Issue 1, 2008), MEDLINE (1980~ March 2008) and Chinese Journal Full-text Database CNKI (1979~2008) for the best available clinical evidence on adjuvant therapy of large area pressure ulcers with infrared rays, nutrition support and some special overlays. Results Two systematic reviews and three randomized controlled trials were included. According to the current evidence, as well as the patient’s clinical condition and preference, a comprehensive therapeutic plan was given to the patient. And in the next three months with the therapeutic plan, the patient’s large area pressure ulcers had already recovered. Conclusion Evidence based approaches can help us develop the best comprehensive therapeutic plan for the patient and will help improve the therapeutic results for patients with large area pressure ulcers.
直肠癌围手术期辅助治疗的提出缘由是直肠癌发病率和死亡率仍不断上升。全球结、直肠癌发病率平均每年递增2%，在欧美国家其死亡率仍居癌症死亡第二位。我国情况亦相似，以上海为例，发病率每年递增4.2%，比全球平均递增速度还要高。1990～1992年我国十分之一人口的抽样调查显示，结、直肠癌平均调整死亡率为4.54/10万人口，居癌症死亡第五位。而直肠癌在美国占结、直肠癌的40%，在中国占50%以上。更甚的是，直肠癌治疗效果还不够理想，近30多年来提高并不显著。美国癌症协会Cutler统计分析25 000例结、直肠癌资料，其中外科治疗直肠癌5年生存率自1940～1960年由44%提高到50%。英国牛津大学临床试验研究中心收集1960～1987年世界各地所有结、直肠癌临床随机治疗资料共计97组154项研究，包含32 000余例，其中直肠癌3年和5年生存率分别为65.0%和45.1%。迄今，大宗直肠癌病例报告的术后5年生存率都徘徊在50%左右，扩大手术范围生存率提高不多，但随之而来的却是更大的手术损伤、合并症增加。术后远处转移，特别是局部复发是直肠癌治疗失败的原因，如何防止局部复发和肝转移，一直是困扰医学家们的临床课题。此外，随着社会进步和科学技术水平的提高，人们对生活质量要求也提高，更多直肠癌患者要求保留肛门。
ObjectiveTo analyze the relation between educational level of patients with colorectal cancer (CRC) and decision-making and curative effect of neoadjuvant therapy (NAT) in the current version of the Database from Colorectal Cancer (DACCA). MethodsThe eligible CRC patients were collected from June 29, 2022 updated DACCA according to the screening criteria and were assigned into 4 groups according to their educational level, namely, uneducated, primary educated, secondary educated, and tertiary educated. The differences in NAT decision-making, cancer marker change, symptomatic change, gross change, imaging change, and tumor regression grade (TRG) among the CRC patients with different educational levels were compared. ResultsA total of 2 816 data that met the screening criteria were collected, 138 of whom were uneducated, 777 of whom were primary educated, 1 414 of whom were secondary educated, and 487 of whom were tertiary educated. The analysis results revealed that the difference in the composition ratio of patients choosing NAT regimens by educational level was statistically significant (χ2=30.937, P<0.001), which was reflected that the composition ratio of choosing a simple chemotherapy regimen in the uneducated CRC patients was highest, while which of choosing combined targeted therapy regimen in the tertiary educated CRC patients was highest. In terms of treatment outcomes, the composition ratios of changes in cancer markers (H=4.795, P=0.187), symptoms (H=1.722, P=0.632), gross (H=2.524, P=0.471), imaging (H=2.843, P=0.416), and TRG (H=2.346, P=0.504) had no statistical differences. ConclusionsThrough data analysis in DACCA, it is found that the educational level of patients with CRC can affect the choice of NAT scheme. However, it is not found that the educational level is related to the changes in the curative effect of patients with CRC before and after NAT, and further analysis is needed to determine the reasons for this.
The incidence of esophagogastric junction adenocarcinoma is gradually increasing, and gastrointestinal surgery and thoracic surgery are paying more and more attention to its surgical treatment. “Chinese expert consensus on the surgical treatment of adenocarcinoma of esophagogastric junction (2018 edition)” discussed the core issues in the field of surgical treatment such as definition, classification, surgical approach, lymphadenectomy, digestive tract reconstruction, and neoadjuvant therapy for esophagogastric junction adenocarcinoma, and gave recommendations. However, there is still some controversy about these issues. The author discussed the consensus and controversial issues relevant to esophagogastric junction adenocarcinoma and related research progress in recent years.
In this paper, systematic reviews, randomized controlled trials and other relevant studies on surgical and adjuvant therapy following operative therapy in renal cancer were identified by searching the Guidelines International Network, ACP Journal Club, the Cochrane Library （Issue 3, 2005 ） , MEDLINE, EMBASE and CBMdisc （ from 1996 to Sept. 2005）. In operative therapy, we found no study comparing operative therapy with no treatment or adjuvant therapy alone; A meta-analysis of cytoreductive nephrectomy in patients with metastatic renal cancer showed adjuvant therapy following nephrectomy was more effective than adjuvant therapy alone; a review comparing radical nephrectomy with nephron-sparing surgery in small-volume renal tumors found similar effectiveness between the two procedures. In the adjuvant therapy following nephrectomy, ten RCTs found adjuvant cytokine therapy （Interferon and Interleukin-2 ） and 5-FU not effective in the adjuvant setting, and could increase adverse reaction; Four RCTs found adjuvant vaccine therapy effective in the adjuvant setting with only a few side effects.
Surgery remains as the primary definitive therapy for resectable non-small cell lung cancer (NSCLC) currently. However, quite a few NSCLC patients, especially in the later stage, suffered tumor recurrence after resection. Safer and more effective perioperative treatment is urgently needed to reduce the recurrence risk after NSCLC surgery. Immune checkpoint inhibitors can effectively prevent tumor immune evasion and have been shown to be a feasible, safe and effective neoadjuvant therapy for resectable NSCLC. Nevertheless, certain crucial problems, including the final effect on NSCLC recurrence, the selection of beneficial group and optimal treatment protocol are yet unsolved. Fortunately, several phase Ⅲ randomized controlled trials are ongoing to answer these questions and will hopefully provide stronger evidence.
ObjectiveTo explore the clinical protocols of neoadjuvant therapy for hepatocellular carcinoma and to provide a perspective on its future prospects. MethodLiterature search and review were conducted in CNKI, Wanfang, VIP, PubMed and other databases using keywords such as “hepatocellular carcinoma”, “neoadjuvant therapy”, “interventional therapy”, “radiotherapy”, “targeted therapy”, “immunotherapy”, etc in recent five years. ResultsNeoadjuvant therapy for hepatocellular carcinoma included neoadjuvant interventional therapy, radiotherapy, targeted therapy, and immunotherapy. Neoadjuvant interventional therapy and radiotherapy had significant advantages for hepatocellular carcinoma patients with portal vein tumor thrombus, while neoadjuvant targeted therapy and immunotherapy had achieved initial results in tumor pathological remission rate, providing more ideas for the diagnosis and treatment of patients with resectable hepatocellular carcinoma. ConclusionsNeoadjuvant therapy is an emerging treatment for hepatocellular carcinoma, which has shown great potential in clinical applications and is moving towards individualization, precision, and systematization. We believe that with in-depth research on the mechanism of immunotherapy for hepatocellular carcinoma and continuous clinical practice, a comprehensive treatment strategy based on immunotherapy will become the key to neoadjuvant therapy for hepatocellular carcinoma in the future.
