前列腺癌大分割调强放疗副反应初步分析

Objective To analyze the acute and late toxicities in patients with prostate cancer trea-ted with hypofractionated intensity-modulated radiotherapy (IMRT). Methods Between June 2006 and June 2008, 37 patients with prostate cancer were treated with hypofractionated IMRT. The clinical target vol-ume (CTV) was the prostate, seminal vesicles and pelvic lymph nodes in 24 patients, the prostate and semi-hal vesicles in 12, and only the tumor bed in 1. The dose per fraction was 2.3 - 2.8 Gy, with 2.7 Gy in 26 patients. The minimal dose was 62.5-75.0 Gy to the prostate and seminal vesicles, and 50 Gy to the pelvic lymph nodes. Results The median follow-up was 14 months. None of the patients experienced grade 4 a-cute gastro-intestinal (GI) toxicity. Grade 1, 2 and 3 acute GI toxicity occurred in 24.3%, 35.1% and 2.7% of the patients, respectively. The rectal V50>27% and V55>20% were highly significantly associat-ed with grade ≥1 acute GI toxicity. Grade 1,2 and 3 acute genitourinary (GU) toxicity occurred in 68%, 0% and 3% of the patients, respectively. The bladder V50> 10% was significantly associated with grade ≥1 acute GU toxicity. The incidence of late GI toxicity was low. No grade ≥3 late GI toxicity was observed. The incidence of late grade 1 and 2 GI toxicity was 24% and 5%, respectively. The rectal V65> 10% was highly significantly associated with grade ≥1 late GI toxicity. No late grade 4 GU toxicity was observed. The incidence of grade 1, 2 and 3 late GU toxicity was 49%, 11% and 3%, respectively. Grade ≥2 late GU toxicity was correlated with V40, V50 and mean dose of the bladder. Conclusions Acute and late toxicity of hypofractionated IMRT is acceptable in patients with prostate cancer.

骨髓涂片免疫组化在形态学难以诊断的急性白血病中的临床研究

目的 分析骨髓涂片免疫组化在急性白血病中的诊断价值.方法 采用骨髓涂片免疫组化,对40例形态学难以诊断的急性白血病进行免疫表型分析,与单独用形态学诊断的结果比对,对两种结果进行一致性检验有差异的与流式细胞仪分型对照.结果 骨髓涂片免疫组化的结果和FCM有较好的一致性,采用免疫表型分析的结果为临床诊断和预后提供了更有力的帮助,对M0和MAL的诊断有决定性的意义,较形态学诊断的结果更好.结论 骨髓涂片免疫组化在形态学难以诊断的急性白血病分型中有较好的临床价值,能更好地进一步分型.

关于医院定编和人事管理若干问题的探讨

目前我国医院编制仍执行１９７８年卫生部颁布的《综合医院组织编制原则试行草案》，２０年来医院实际情况发生了很大变化，如何科学合理地制定医院各类人员的编制标准是卫生改革应研究的问题之一，也是深化人事制度改革的重要课题。一、医院人员编制存在的问题传统的人事...     

急性心肌梗死患者Plt、MPV、PDW的变化观察

目的观察急性心肌梗死（AMI）患者血小板计数（Plt）、血小板平均体积（MPV）、血小板分布宽度（PDW）的变化情况。方法用血细胞分析仪检测23例AMI患者1周内的Plt、MPV、PDW,并与非梗死组作对照。结果AMI组患者MPV、PDW明显高于对照组（P均〈0.05）,Plt减少至第5—6天恢复正常。结论AMI患者Plt、MPV、PDW均发生变化,MPV的增加是AMI重要的危险因素之一,在临床上有一定的应用价值。     

Comparison of acute toxicities between two postoperative concurrent chemoradiotherapy regimens of capecitabine with or without oxaliplatin in patients with stage Ⅱ and Ⅲ rectal cancer

Objective To compare the acute toxicities between two prospective, non-randomize phase Ⅱ trials on adjuvant radiochemotherapy of capecitabine with or without oxaliplatin in patients with stage Ⅱ and Ⅲ rectal cancer. Methods From March 2005 to November 2007,based on two fulfilled phase Ⅰ studies,two phase Ⅱ trials were launched respectively to further observe the tolerance and toxicity. In one tria1,118 patients were treated with concurrent capecitabine and radiotherapy (Cap-CRT trial), with radio-therapy of DT50 Gy/25 F/5 wks to the pelvis, and capecitabine at a dose of 1600 mg/m2/d(d1-d14,3 weeks per cycle). In the other trial, 90 patients received concurrent oxaliplatin, capecitabine and radiothera-py(Cap-Oxa-CRT trial), with the same radiotherapy schedule, while oxaliplatin at a dose of 70 mg/m2(d1, d8) and capecitabine of 1300 mg/m2/d(d1-d14,3 weeks per cycle). Results There was no significant difference in the delay of radiotherapy (10.2% vs 6.7%, X2=0.80, P=0.460) or chemotherapy (9.3% vs 19.1%, X2=4.80,P=0.090) between Cap-CRT and Cap-Oxa-CRT trials. Grade 1-4 leukopenia,diar-rhea and nausea were the most common acute side-effects in the both trials, accounting for 70.2%, 65.9% and 42.3%, respectively. When comparing with Cap-CRT trial, Cap-Oxa-CRT trial had significantly more grade 1-4 non-hemotological toxicities, mainly in Gl,including nausea (68.9% vs 22.0%, X2=46.90, P= 0.000), diarrbea(76.7% vs 57.6%, X2=13.50, P=0.009), fatigne(47.8% vs 13.7%, X2=18.90,P= 0.000), hand-foot syndrome (14.4% vs 4.2%, X2=7.10, P=0.029), and inappetence (50.0% vs. 27.9%, X2 = 25.70, P=0.000), but not in hematological toxities of leukopenia, anemia or thrombocytope-nia. Of all the patients,grade 3 and grade 4 toxicities were diarrhea(24.0% and 1.0%),leukopenia(4.3% and 0.0%),radiation-induced dermatitis(3.8% and 0.0%),cramping abdominal pain(1.0% and 0.0%) and fatigue(0.5% and 0.0%). Only grade 3 and 4 diarrhea was significantly more in Cap-Oxa-CRT trial than in Cap-CBT trial(33.0% vs 18.6%, X2=5.90,P=0.023). Conclusions For patients with stage Ⅱ and Ⅲ rectal cancer,both the postoperative concurrent radiochemotherapy regimens are tolerable,though Cap-Oxa-CRT trial has more grade 3 and 4 diarrhea.
