Clinicopathological features of adult Wilms tumor with BRAF V600E mutation / 中华病理学杂志

Objective: To identify BRAF V600E mutations in adult Wilms tumor (WT) with overlapping histologic features of metanephric adenoma (MA) and to investigate the clinicopathological features of adult WT. Methods: The clinical features of adult WT diagnosed at the Fudan University Shanghai Cancer Center, Shanghai, China from 2012 to 2021 were reviewed. HE-stained slides of all cases were reviewed by 2 expert pathologists. Representative tissues were selected for BRAF V600E immunohistochemical (IHC) staining and gene sequencing. Results: In adult WT with MA-like areas (cohort Ⅰ, n=6), 5 of the 6 cases were composed of epithelial-predominant and were positive for WT-1 and CD56, respectively, and all were positive for CD57. All 6 cases revealed highly variable Ki-67 indices, ranging from 1% in some areas to 60% in others. 5 of the 6 cases harbored a BRAF V600E mutation. All cases in cohort I were followed up for 23 to 71 months, and all survived. In classical adult WT without MA-like areas cohort (cohort Ⅱ, n=13), all 7 cases with available material were negative for BRAF by IHC and none of them had any BRAF mutation. Conclusions: BRAF V600E mutations are frequently present in adult WT with overlapping morphologically features of MA, but not in those without. More importantly, adult WTs with overlapping histologic features of MA may be an intermediate entity between typical MA and WT that may have a favorable prognosis and possible therapeutic targets.

Assessment on the capacity for prevention and control programs for chronic non-communicable diseases in China, in 2014 / 中华流行病学杂志

Objective: To assess the capacity of prevention and control on chronic non- communicable diseases (NCDs) in China. Methods: On-line questionnaire survey was adopted by 3 395 CDCs at provincial, municipal and county (district) levels and 3 000 primary health care units, and assess on capacity of policy, infrastructure, capacity of training and guidance, cooperation, surveillance, intervention and management, assessment and scientific research from September 2014 to March 2015. Results: (1) Capacity of policy: 23 (71.9%) provincial, 139 (40.6%) municipal and 919 (31.2%) county (district) governments or health administrative departments had existing plans for prevention and control of NCDs. (2) Capacity of infrastructure: 25 (78.1%) provincial, 136 (39.8%) municipal and 529 (18.0%) county (district) CDCs had set up departments dedicated to the prevention and control of NCDs, with 9 787 staff members, accounting for 5.0% of the total CDC personnel, working on NCDs prevention and control programs. 68.1% of the CDCs had special funding set for NCDs prevention and control. (3) Capacity of training and guidance: 2 485 CDCs (74.9%) held all kinds of training on prevention and control of NCDs. 2 571 (87.3%) CDCs at the county (district) level provided technical guidance for primary health care units. (4) Capacity of cooperation: 42.0% of the CDCs had experiences collaborating with the mass media. (5) Capacity of surveillance: 73.8% of the CDCs had set up programs for death registration while less than 50.0% of the CDCs had implemented surveillance programs on major NCDs and related risk factors. In terms of primary health care units, 32.4% of them had set up reporting system for newly developed stroke case and 29.9% of them having programs on myocardial infarction case reporting. (6) Capacity of intervention and management: 69.1% and 68.2% of the CDCs conducted individualized intervention programs on hypertension and diabetes, while less than 40.0% CDCs conducting intervention programs on other NCDs and risk factors. More than 90.0% of the primary health care units carried out follow-up surveys on hypertension and diabetes. However, only 17.4% and 13.7% of the CDCs working on hypertension and diabetes patient management programs while 83.7% and 80.4%, of them following the standardized guidelines for management, with successful rates of control as 59.2% and 55.2%, respectively. (7) Capacity of assessment: 32.4% of the CDCs or health administrations carried out evaluation programs related to the responses on NCDs. (8) Capacity of scientific research: the capacity on scientific research among provincial CDCs was apparently higher than that at the municipal or county (district) CDCs. Conclusions: Compared with the results of previous two surveys, the capacity on policies set for the prevention and control programs improved continuously, at all level NCDs, but remained relatively weak, especially at both county (district) and primary health care units.
