液基涂片细胞学检查联合高危型HPV检测在宫颈病变诊断中的价值

目的 探讨液基涂片细胞学(TCT)检查联合高危型人乳头瘤病毒(HPV)检测在宫颈病变诊断中的价值.方法 收集500例宫颈脱落细胞标本,采用宫颈细胞学检查、HPV DNA检测或2种方法联合检查后,选择所有的HPV阳性和TCT报告为意义不明确的不典型鳞状细胞(ASC-US)以上者,均通过阴道镜取活检,以组织学诊断为金标准,比较宫颈细胞学检查、HPV DNA检测及以上2种方法联合检查与组织病理学诊断的符合率、灵敏度和特异度.结果 313名TCT报告为ASC-US以上者,与组织病理学诊断的符合率为82.4％.268名检测结果为HPV DNA阳性的女性与组织病理学诊断的符合率为77.2％.2种方法联合检查251名女性,与组织病理学诊断的符合率为92.0％.TCT联合HPV DNA检测与单纯HPV DNA检测比较,差异有统计学意义(P＜0.01).TCT联合HPV DNA检测与单纯TCT比较,差异有统计学意义(P＜0.01).HPV DNA检测诊断宫颈癌的灵敏度为83.8％,特异度为75.9％,TCT检测诊断宫颈癌的灵敏度为93.5％,特异度为75.4％,TCT检查联合HPV DNA检测诊断宫颈癌的灵敏度为96.3％,特异度为87.5％.结论 TCT联合HPV DNA检测在宫颈病变筛查中比单纯TCT或单纯HPV DNA检测更具有实用价值.     

Timely follow‐up of positive cancer screening results: A systematic review and recommendations from the PROSPR Consortium

Timely follow‐up for positive cancer screening results remains suboptimal, and the evidence base to inform decisions on optimizing the timeliness of diagnostic testing is unclear. This systematic review evaluated published studies regarding time to follow‐up after a positive screening for breast, cervical, colorectal, and lung cancers. The quality of available evidence was very low or low across cancers, with potential attenuated or reversed associations from confounding by indication in most studies. Overall, evidence suggested that the risk for poorer cancer outcomes rises with longer wait times that vary within and across cancer types, which supports performing diagnostic testing as soon as feasible after the positive result, but evidence for specific time targets is limited. Within these limitations, we provide our opinion on cancer‐specific recommendations for times to follow‐up and how existing guidelines relate to the current evidence. Thresholds set should consider patient worry, potential for loss to follow‐up with prolonged wait times, and available resources. Research is needed to better guide the timeliness of diagnostic follow‐up, including considerations for patient preferences and existing barriers, while addressing methodological weaknesses. Research is also needed to identify effective interventions for reducing wait times for diagnostic testing, particularly in underserved or low‐resource settings.

子宫颈鳞癌患者放疗前后血清铜、锌的变化

目的检测子宫颈癌患者放疗前后血清铜、锌的变化，检测子宫颈癌患者与正常人血清铜、锌水平的比较。材料与方法采用三电极直流等离子原子发射光电直读光谱仪法检测。结果子宫颈鳞癌患者血清铜（ＳＣｕ）、铜锌比值（Ｃｕ／Ｚｎ）显著高于正常对照组（Ｐ＜０．００１），Ⅲ期患者又显著高于Ⅱ期患者（Ｐ＜０．００１）；放疗后癌灶完全消退者（ＣＤ）ＳＣｕ、Ｃｕ／Ｚｎ明显下降（Ｐ＜０．０１）；部分消退者（ＰＤ）二值仍处于高水平。结论：ＳＣｕ和Ｃｕ／Ｚｎ可以检测放疗疗效，估计预后，有一定临床意义。     

HPV genotyping in cervical cancer in Northern Thailand: adapting the linear array HPV assay for use on paraffin-embedded tissue

ObjectiveThe objective of this study was to review our experience with abdominal radical trachelectomy in patients with early-stage cervical cancer.MethodsWe performed a retrospective review of all patients who underwent an abdominal radical trachelectomy at the Instituto de Cancerologia—Clinica las Americas in Medellin, Colombia, between April 2002 and January 2008. Data collected included age, stage, histopathologic subtype, tumor size, evidence of lymph-vascular space invasion, estimated blood loss, number of perioperative blood transfusions, number and disease status of lymph nodes removed, disease status of surgical specimen, length of hospital stay, intraoperative and postoperative complications, follow-up time, and fertility outcomes.ResultsFifteen patients underwent an abdominal radical trachelectomy during the study period. The median patient age was 30 years (range, 25–38). Three patients had stage IA2 and 12 had stage IB1 cervical cancer. Eleven patients had squamous cell carcinoma and 4 had adenocarcinoma. Thirteen patients were diagnosed by cervical conization and 2 by colposcopically directed biopsy. All patients had tumors smaller than 2 cm. The median estimated blood loss was 400 ml (range, 200–1000). The median surgical time was 265 min (range, 210–330). The median number of units of packed red blood cells transfused per patient was 2. The median number of lymph nodes removed was 26 (range, 11–48). The median length of hospitalization was 3 days (range, 2–7). The median follow-up time was 32 months (range, 5–32). There was 1 intraoperative complication and 6 postoperative complications in 4 patients. No patient has had a recurrence. Three patients were able to conceive spontaneously; 1 delivered at 31 weeks' gestation, and 2 delivered at term.ConclusionAbdominal radical trachelectomy is feasible and can be performed safely in a developing country in well-selected patients with early cervical cancer who wish to preserve their fertility.
