ABSTRACT
Objective To investigate the relationship between prothrombin fragment 1+2 (F1+2) and peripherally inserted central catheter (PICC) associated thrombosis in cervical cancer patients, and provide certain clinical basis of early prevention in peripherally inserted central catheter associated thrombosis in cervical cancer patients. Methods One hundred and forty cervical patients with PICC were enrolled in this study, and they were divided into thrombosis group (35 patients) and non-thrombosis group (105 patients). The level of F1+2 was examined using enzyme-linked immunoassay, and was analyzed according to the clinic features. Results The level of F1+2 was correlated with clinical stage (r = 0.640, P = 0.004);but was not correlated with age, type of tumor and concurrent radiochemotherapy (P>0.05). The level of F1+2 in thrombosis group was (520.343 ± 121.759) pmol/L, in non- thrombosis group was (388.361 ± 104.873) pmol/L, and there was significant difference (P =0.001). The multi-factors Logistic analysis showed that the level of F1+2 (OR=1.011, P=0.001) and age (OR = 21.025, P = 0.031) were independent risk factors for the PICC associated with thrombosis in cervical cancer. Conclusions The level of F1+2 is closely related with clinical stage and PICC associated thrombosis, and it is an independent risk factor for the PICC associated with thrombosis in cervical cancer.
ABSTRACT
Objective To investigate the application value of extracorporeal extended field radiotherapy in locally advanced cervical cancer. Methods A total of one hundred and twenty patients with stage IIB?IVA cervical cancer in the First Affiliated Hospital of Hebei North University from June 2012 to June 2014 were randomly divided into two groups:the control group and the observation group,each with 60 cases. The routine concurrent chemoradiotherapy was adopted in the control group. The observation group was treated with extracorporeal extended field radiotherapy combined with concurrent chemotherapy. The patients have been followed up for three years. The total efficacy rate,toxicity reaction,local progression free survival time ( PFS) and survival rate of the two groups were compared. Results The total efficacy rate in the observation group was significantly higher than that of the control group ( 88. 3%( 53/60 ) vs. 73. 3%( 44/60 ) , χ2 = 4. 357, P=0. 037),while the incidences of toxicity reaction in the two groups were 18. 3%(11/60) and 16. 7%(10/60), the difference was not statistically significant (χ2=0. 058,P=0. 810) ,the percentages of I and II degree in the two groups were 3. 4%( 2/60 ) and 3. 4%( 2/60 ) , the difference between the two groups was not statistically significant (Z=0. 000,P=1. 000). The PFS value in the observation group was significantly longer than that of the control group ( 25. 6 months vs. 13. 8 months,χ2 = 25. 624, P= 0. 000 ) , and the survival rate in the observation group improved significantly ( 53. 3%( 32/60 ) vs. 33. 3%( 20/60 ) , the difference was statistically significant (χ2 = 4. 887, P= 0. 027 ) . Conclusion Extracorporeal extended field radiotherapy is safe and effective in the treatment of locally advanced cervical cancer.
ABSTRACT
ObjectiveTo discuss the application value of high frequency ultrasound (HFUS) characteristics, acoustic radiation force impulse (ARFI) imaging technology and contrast-enhanced ultrasound (CEUS) in the diagnosis of soft tissue hemangioma.MethodsTo retrospectively analyze the clinical data of 44 cases of soft tissue hemangioma that were treated in Capital Medical University Affiliate Beijing Chaoyang Hospital from August, 2013 to May, 2014, and to analyze the difference between the characteristics of HFUS, ARFI and CEUS in soft tissue hemangioma and normal surrounding tissue.ResultsHFUS shows the features of morphological diversity of sinus shape expansion tube structure, unclear boundary, irregular configuration, compressibility and partial strong echo in the phlebolith. Color Doppler ultrasound (CDFI), detects abundant interphase red-blue bloodstream signal slowly and consistently. The blood signal is strengthened after partial compression. CDFI shows more vein spectrum in the lesion. The discrepancy of comparison between VTQ and SWV value of soft tissue hemangioma and surrounding muscular tissue possesses statistical significance [(1.082±0.183) m/svs (1.414±0.331) m/s,P<0.01]. Ultrasound contrast can show the relationship between diseased region and surrounding tissue clearly, which is beneficial to the selection of operation method and prognosis.ConclusionThrough conventional two-dimensional ultrasound and high frequency CDFI, and further combining the acoustic pulse radiation ARFI technology and CEUS technology, the soft tissue hemangioma can’t only be more accurately diagnosed, but also provides more reliable diagnostic basis for clinic.
