Case report form (CRF) is a key document for data collection in clinical trials. A well-designed CRF is required for database construction, data accuracy, data query/cleaning, CRF completion and statistical analysis. A well-defined process or SOP should be in place for CRF design. Data collection should fully meet the demand of study protocol. The layout of CRF should be clear with well-structured fields and standard coding for fields.

Objective To investigate essentiality of bone scintigraphy in patients with renal cellcarcinoma.Methods The clinical data of 152 patients with confirmed renal cell carcinoma from Jan uary 1999 to June 2007 were retrospectively analyzed.There were 106 men and 46 women with a meanage of 56 years (range 11-86 years).The tumor size was 1.5-20.0 cm (mean 6.0 cm).Accordingto the TNM and AJCC staging classification,88 patients had stage I,included of T1a in 47 cases,T1bin 41; 38 had stage Ⅱ; 16 had stage Ⅲ,included of T3a,in 10 cases,T3b in 6; and 10 had stage Ⅳ.Histological grade was well differentiated in 90 cases,moderately in 43,poor in 19.Ten clinical pa thology factors were evaluated by Logistic analysis to present the significant factors related to osseousmetastatic lesions.Results Overall osseous metastatic lesions were present in 22 of the 152 patients(14.5%).Of the 126 patients with clinically localized,11 cases (8.7%) had osseous metastatic le sions.Of the 16 patients with clinically advanced,5 eases (31.2%) had osseous metastatic lesions.Ofthe 10 patients with metastasis,6 cases(60%) had osseous metastatic lesions.Clinical stage was re lated to osseous metastatic lesions by Logistic analysis.The incidence of osseous metastatic lesionswas 40.9% in localized renal cell carcinoma patients with bone pain.Conclusions Bone seintigraphymay be omitted in patients with clinically localized renal ceil carcinoma(stage Ⅰ,Ⅱ) unless bone pain is pres ent.Bone scintigraphy should be performed in patients with stage Ⅲ or Ⅳ regardless of symptoms.

Objective To assess the depression and cognition function in patients with severe obstructive sleep apnea (OSAHS) , and to study the relationship between the depression and severity of OSAHS, cognition disorders. Methods A total of 74 OSAHS patients (OSAHS group) and 39 normal controls ( control group) which all diagnosed by polysomnography (PSG) were chosen, and they were assessed the state of depression by self-rating depression scale ( SDS) and for cognition disorders by mini-mental state examination ( MMSE ). Results The score of SDS in OSAHS group was significantly higher than that in the control group(P<0.01). In patients with OSAHS , the score of SDS was positively correlated with apnea hyponea index ( AHI) , which was negatively correlated with mean level of SaO_2 ( MSaO_2 ) and the lowest SaO_2 ( LSaO_2 ) (P<0.01 ). The score of MMSE in OSAHS group was significantly lower than that in the control group, which was negatively correlated with AHI(P<0.01) and positively correlated with MSaO_2 and the lowest LSaO_2(P<0.01 ). The score of SDS was negatively correlated with MMSE( r= -0.505, P<0.01). Conclusion OSAHS patients exit depression and cognition disorders, which was correlation to intermitten hypoxemia in frequently.

Objective To evaluate the impact of different anatomical landmarks on registration in imaging-guided radiation (IGRT) for lung cancer. Methods For 20 patients with non-small cell lung cancer receiving stereotactic body radiotherapy (SBRT) in Fudan University Cancer Hospital, 100 frames of kilo-voltage cone-beam computed tomography scanning were evaluated in this study. The spine, carina and tumor were selected as landmarks for registration, respectively. Results of registration using different landmarks were documented and compared. Results The average set-up errors in the left-right, superiorinferior and anterior-posterior directions were -0. 08 cm ±0. 32 cm, -0. 16 cm ±0. 45 cm and 0. 06 cm ±0. 23 cm with the spine for registration;0. 06 cm ±0. 34 cm, -0. 13 cm ±0. 45 cm and -0. 02 cm±0.23 cm with the carina;and -0. 17 cm ±0.25 cm, 0.03 cm ±0.47 cm and 0. 15 cm ±0.38 cm with tumor. The registration results between using the carina and tumor as landmarks were statistically significant different (q=4.61, P=0. 002 ;q = 2. 23 , P=0. 118;q=3.44, P=0. 017). The registration results were equal when using the spine and tumor as landmarks ( q = 1.85, P = 0. 195; q = 2. 54, P = 0. 075; q = 1.89,P=0. 185), as well as using the carina and tumor as landmarks (q=2.76, P=0. 054;q=0.31, P=0. 826 ;q = 1.55, P = 0. 276). Conclusions For early stage lung cancer, the spine and tumor can be used equally as registration landmarks in imaging-guided SBRT. The carina is not suggested for its poor reproducible position.
