目的分析Ⅰ-ⅡA期肺腺癌根治术后复发转移的危险因素,构建Ⅰ-ⅡA期肺腺癌根治术后复发转移的预测模型。方法行肺癌根治术并经病理确诊为Ⅰ-ⅡA期LUAD患者205例,收集患者的临床资料,包括性别、年龄、吸烟史、术前肺功能、肿瘤位置、肿瘤... 目的分析Ⅰ-ⅡA期肺腺癌根治术后复发转移的危险因素,构建Ⅰ-ⅡA期肺腺癌根治术后复发转移的预测模型。方法行肺癌根治术并经病理确诊为Ⅰ-ⅡA期LUAD患者205例,收集患者的临床资料,包括性别、年龄、吸烟史、术前肺功能、肿瘤位置、肿瘤最大直径、淋巴结清扫数目、术后病理见微乳头结构、胸膜侵犯、脉管癌栓、辅助化疗情况、术前血清癌胚抗原(CEA)水平、术前中性粒细胞计数与淋巴细胞比值(NLR)、术前预后营养指数(PNI),统计患者术后复发转移情况;采用Kaplan-Meier法绘制生存曲线,联合log-rank法分析Ⅰ-ⅡA期LUAD术后复发转移的相关因素;采用COX比例风险模型分析Ⅰ-ⅡA期LUAD术后复发转移的独立危险因素。使用R语言软件构建Ⅰ-ⅡA期LUAD根治术后复发转移风险预测列线图。采用Bootstrap法对列线图进行内部验证,计算该列线图的C-index值;绘制列线图的ROC曲线,评价列线图的区分度;采用校准曲线评价列线图的一致性。结果肿瘤最大直径、术后病理见微乳头结构、术前肺功能、术前血清CEA水平、术前NLR、术前PNI与Ⅰ-ⅡA期LUAD根治术后复发转移有关(P均<0.05),其中肿瘤最大直径>3 cm、术前血清CEA>5 ng/mL、术前NLR>2.285、术前PNI≤46.625是Ⅰ-ⅡA期LUAD根治术后复发转移的独立危险因素(P均<0.05)。构建了Ⅰ-ⅡA期LUAD根治术后复发转移风险预测列线图。列线图的C-index值为0.814(95%CI为0.751~0.877),该列线图预测Ⅰ-ⅡA期LUAD根治术后2年、3年、5年复发转移的ROC的AUC分别为0.757(95%CI为0.641~0.874)、0.696(95%CI为0.595~0.797)、0.675(95%CI为0.589~0.762),Ⅰ-ⅡA期LUAD根治术后复发转移风险预测列线图的校准曲线均接近参考线。结论Ⅰ-ⅡA期LUAD根治术后复发转移的独立危险因素为肿瘤最大直径>3 cm、术前血清CEA>5 ng/mL、术前NLR>2.285、术前PNI≤46.625。成功构建了Ⅰ-ⅡA期LUAD根治术后复发转移风险预测模型,且模型的区分度与一致性均较好。 展开更多

Objective:To evaluate the current approaches for multimodality therapy for stage ⅠB cervical cancer.Methods:The relevant literature has served as a source for identified high or intermediate risks and management of stage ⅠB cervical cancer.Result:The high risks include pelvic lymph node metastasis(PLNM),positive resection margin(PRM),and the involvement of parametrium(IPM).The intermediate risks include deep stromal invasion(DSI),bulky tumor size(BTS),lymphovascular space invasion(LVSI).Adeno-carcinomatous histotype is the new risk feature relevant to poor prognoses.Both radical hysterectomy plus bilateral pelvic lymph node dissection(PLND) and radical radiotherapy have proven to be equally effective.Surgery is more performed for stage ⅠB1 disease;radiotherapy or chemoradiotherapy is preferable for stage ⅠB2 disease.For patients with one high risk or two of intermediate risks,radical hysterectomy plus PLND followed by concurrent chemoradiotherapy can improve overall survival(OS) and disease-free survival(DFS).Conclusion:The management should be individualized for stage ⅠB cervical cancer.The optimized multidisciplinary therapy can benefit patients with the best cure and minimum morbidity and complications. 展开更多

Objective:To evaluate the toxicity of paclitaxel and cisplatin combination in patients with advanced ovarian cancer.Methods:A retrospective review was performed on patients with stage Ⅲ or stage Ⅳ ovarian cancer treated in QiLu hospital between October 1996 and June 1999 Results:26 patients received adjuvant paclitaxel and cisplatin chemotherapy.The significant toxicity included:anemia 7/26(27%),thrombocytopenia 10/26(38%),neutropenia 19/26(73%),nausea or vomiting 24/26(92%) and neurotoxicity 11/26(42%).No patient delayed.No patient died during treatment.Conclusion:The dosages of primary paclitaxel and cisplatin chemotherapy is reasonably well tolerated for patients with stage Ⅲ or Ⅳ ovarian cancer. 展开更多
