OBJECTIVE:
To explore the value of transthoracic echocardiography (TTE) in transcatheter closure of atrial septal aneurysm (ASA) combined with secoundum-type atrial septal defect (ASD).
METHODS:
Fourteen patients (3 males and 11 females) who had ASA combined with secoundum-type ASD were diagnosed by TTE or transesophageal echocardiography. The ASA projected to the right atrium in all patients. The width of basilar part was 13 approximately 24 (18.5+/-3.9) mm, and the vertical extent was 7 approximately 11(9.7+/-1.8) mm. Ten patients combined with single hole ASD and 4 patients with multiple hole ASD. Blood shifting from the left atrium to the right atrium was displayed in color Doppler in all patients. All patients were treated by transcatheter closure under the guiding of X fluoroscopy and TTE, and examined with TTE during the follow-up.
RESULTS:
Transcatheter closure was successfully performed by 14 occluders in all patients. No residual shunt was detected immediately by TTE after the procedure in all patients. During the 6 approximately 12 month follow-up, no residual shunt or occluder shifting was found, the dimensions of the heart became normal in 11 patients (79%) and were significantly decreased in 4.
CONCLUSION
Transcatheter closure is feasible in patients with ASA combined with secoundum-type ASD, and extra attention must be paid to the specialty. TTE is very important in case selection before transcatheter closure, and it may be used to monitor and guide the procedure during transcatheter closure.

OBJECTIVETo evaluate the effect of thoracic radiation therapy (TRT) on patients with extensive stage small-cell lung cancer (SCLC).
METHODSOne hundred and fifty-four patients with extensive stage SCLC treated in our department between January 2003 and December 2006 were enrolled in this study. Eighty nine patients received chemotherapy and thoracic radiation therapy (ChT/TRT), and 65 patients were treated with chemotherapy alone (ChT without TRT). The chemotherapy was CE (carboplatin and etoposide), PE (cisplatin and etoposide) or CAO (CTX, ADM and VCR) regimens. The total dose of thoracic irradiation was 40-60 Gy with 1.8 - 2.0 Gy per fraction.
RESULTSFor the whole group, the median survival time (MST) was 13.7 months, the 2-year and 5-year overall survival rates were 27.9% and 8.1%, respectively. The MST, overall survival rates at 2 years and 5 years in the ChT/TRT group and ChT without TRT group were 17.2 months, 36.0%, 10.1% and 9.3 months, 16.9%, 4.6%, respectively (P = 0.001). The median progression-free survival (PFS) for all patients was 8.0 months, the 2-year and 5-year PFS were 13.6% and 8.2%, respectively. The median PFS, 2-year and 5-year PFS in the ChT/TRT group and ChT without TRT group were 10.0 months, 17.4%, 10.5% and 6.2 months, 9.8%, 4.9%, respectively (P < 0.001). The incidence of intra-thoracic local failure was 29.6% in the ChT/TRT group and 70.0% in the ChT/without TRT group (P = 0.000).
CONCLUSIONSChemotherapy plus thoracic radiation therapy can improve the overall survival, progress free survival and reduce local regional failure rate in patients with extensive stage SCLC compared with that by chemotherapy alone.

OBJECTIVETo develop quality of life questionnaire of Chinese medicine for postoperative patients with colorectal cancer (QLQ-CMPPCC), thus comprehensively and objectively evaluating the clinical efficacy of Chinese medicine and pharmacy in treating postoperative patients with colorectal cancer (CC).
METHODSThe theoretical structure model of the questionnaire was addressed in combined with basic theories of Chinese medicine according to the principle of WHO quality of life (QOL). The primary questionnaire was developed using methods of structuralization policy making after we extensively retrieve various universal and specific questionnaires for CC cancer patients at home and abroad. The 205 CC patients were tested by questionnaire. The items were screened using experts grading method, item selection analysis, dispersion trends of standard deviation, t-test, correlation coefficient method, factor analysis,and Cronbach's alpha.
RESULTSThe QLQ-CMPPCC was developed containing four domains of physical, psychological, independence, and social functions, involving 20 aspects and 54 items. Of them, non-fistula patients answered 43 items and fistula patients answered 46 items. One item covered the general QOL evaluation.
CONCLUSIONSQLQ-CMPPCC showed Chinese medical features. It comprehensively reflected the connotation of QOL for postoperative CC patients. It could be taken as a tool for evaluating Chinese medical efficacy for postoperative CC patients.

OBJECTIVETo investigate the prognostic factors and the principles of treatment of primary esophageal small cell carcinoma (SCEC) retrospectively.
METHODSThe data of 126 patients with histologically confirmed SCEC treated in our department between May 1985 and June 2005 were retrospectively analyzed. 85 patients were in limited disease stage (LD) and 41 patients as extensive disease stage (ED) according to the Veterans Administration Lung Study Group staging system. Among the 84 patients treated with esophagectomy, 8 cases were in stage I, 16 in stage IIa, 10 in stage IIb, 40 in stage III, 4 in stage IVa and 6 in stage IVb, according to the TNM system (6(th) edition, AJCC). Cox's hazard regression model was used to identify the prognostic factors, and Chi-square test to detect the difference of frequencies among different groups. Kaplan-Meier and log-rank methods were used to estimate and compare the survival rates.
RESULTSThe median follow-up duration of this series was 13 months. One hundred and eight patients died of the disease during the follow-up, 10 were still alive and 8 were lost to follow-up. The 1-, 3-, and 5-year overall survival rates (OS) were 52.2%, 15.9%, and 12.2%, respectively, with a median survival time (MST) of 12.5 months. The 1-, 2-, and 3-year OS were 62.1%, 30.8%, and 22.4% with a MST of 14.0 months for LD, and 29.3%, 13.6% and 2.7% with a MST of 7.0 months for ED, respectively. There was a statistically significant difference in OS between LD and ED (P = 0.0001). The MST of the patients treated with chemotherapy was 14.5 months, significantly longer than the 5.2 months of the patients without (P = 0.0001). Multivariate analysis showed that stage (HR 1.91, 95% CI 1.26 approximately 2.91, P = 0.002), length of the primary lesion (HR 1.75, 95% CI 1.17 approximately 2.63, P = 0.007), and chemotherapy (HR 0.42, 95% CI 0.28 approximately 0.65, P = 0.000) were independent prognostic factors.
CONCLUSIONEsophageal small cell carcinoma is a systemic disease. The tumor stage (LD or ED), length of the primary lesion and chemotherapy are independent prognostic factors. Therefore, a systemic therapy based on chemotherapy should be recommended.

OBJECTIVETo analyze the influence of the number of lymph node metastasis on survival and prophylactic postoperative radiotherapy after radical resection of thoracic esophageal carcinoma.
METHODSFour hundred and ninety-five patients with thoracic esophageal squamous cell cancer who had undergone radical resection were randomly divided into surgery group alone (S, 275) and surgery plus radiotherapy group (S + R, 220). The patients were classified into three groups: Group A: 234 patients (47.2%) without lymph node involvement; Group B: 146 patients (29.5%) with 1 to 2 involved lymph nodes and Group C: 115 patients (23.2%) with >or= 3 involved lymph nodes.
RESULTS1. The 5-year survival rate in Groups A, B and C for the same T stage (T3) was 52.6%, 28.8% and 10.9%, respectively (P = 0.0000); the 5-year survival rate in group C was 0% in S group and 19.3% in S + R group (P = 0.0336); 2. In the positive lymph node group, the metastatic rate of intra-thoracic and supraclavicular lymph node was 35.9% and 21.2% in S group and 19.7% and 4.4% in S+R group (P = 0.014 and P = 0.000). In the negative lymph node group, the metastatic rates of intra-thoracic lymph node was 27.8% in S group and 10.3% in S + R group (P = 0.003). The metastatic rate of intra-abdominal lymph node in Groups A, B and C was 3.9%, 9.4% and 17.5%, respectively (P = 0.0000). The occurrence of hematogenous metastasis was most frequent in group C (27.8%) with >or= 3 positive lymph nodes.
CONCLUSION1. The number of metastatic lymph node is one of the important factors which affects the survival of thoracic esophageal carcinoma. 2. Chemotherapy might be given to the patients with three or more lymph nodes involved who have the possibility of developing hematogenous metastasis. Postoperative radiotherapy can reduce the occurrence of intra-thoracic and supraclavicular lymph node metastasis and improve the survival of patients with three or more lymph nodes involvement.

OBJECTIVETo evaluate the association between polymorphism of transforming growth factor-β1 (TGF-β1)-509C/T and radiochemotherapy response and survival in esophageal squamous cell carcinoma (ESCC) patients.
METHODSThe genotype of TGF-β1-509C/T was detected by polymerase chain reaction-based restriction fragment length polymorphism assay (PCR-RFLP) in 230 ESCC patients receiving radiotherapy alone or in combination with chemotherapy. Unconditional multivariate logistic regression analysis was done to estimate adjusted odds ratios (ORs) along with the corresponding 95% confidence intervals (CIs) for the polymorphism and radiochemotherapy response. The associations between overall survival time or hazard ratio (HR) of ESCC patients and genetic variation or the clinical data were estimated by applying univariate and multivariate Cox-regression analyses.
RESULTSAmong 208 patients with upper gastrointestinal contrast assessment, 87 cases were susceptible to radiochemotherapy treatment and the TGF-β1-509CC, CT and TT genotype patients were 17 (19.5%), 48 (55.2%) and 22 (25.3%), respectively. Among the patients who were insensitive to radiochemotherapy treatment (n = 121), the TGF-β1-509CC, CT and TT genotype patients were 39 (32.2%), 54 (44.6%) and 28 (23.2%), respectively. Compared with TGF-β1-509CC genotype, the CT and TT genotype carriers had a significantly better treatment response (adjusted OR = 2.07, 95%CI, 1.05 - 4.09, P = 0.036). The median survival time of CC genotype patients was 17.0 (95%CI, 12.0 - 23.0) months, CT genotype patients was 22.0 (95%CI, 16.0 - 33.0) months and TT genotype patients was 25.0 (95%CI, 15.0 - 41.0) months. Compared to CC genotype patients, the survival time difference of CT and TT group was close to the statistical break point (P = 0.063). Our data showed that the subjects with CT or TT genotype had an decreased HR respectively as compared with those with CC genotype (CT, adjusted HR = 0.81, 95%CI, 0.52 - 1.24; TT, adjusted HR = 0.86, 95%CI, 0.65 - 1.12), but the difference was not statistically significant (P > 0.05). However, tumor location, clinical stage and radiochemotherapy response affected the overall survival time of the patient significantly (adjusted HR = 1.28, 95%CI: 1.01 - 1.61, P = 0.040; 1.49, 95%CI, 1.17 - 1.88, P = 0.001; 1.55, 95%CI, 1.06 - 2.26, P = 0.023, respectively).
CONCLUSIONThese results suggest that TGF-β1-509C/T polymorphisms were associated with radiochemotherapy for esophageal squamous cell carcinoma which might be genetic markers for prediction of the radiochemotherapy response in ESCC patients.

OBJECTIVETo compare the treatment results of three-dimensional conformal radiotherapy (3D-CRT) and conventional radiotherapy (2D) for patients with locally advanced non-small-cell lung cancer (NSCLC).
METHODSFive hundred and twenty seven patients with stage III NSCLC treated between Jan 2000 and Dec 2006 were included in this study. Among them, 253 cases were treated with 3D-CRT, and 274 with conventional radiotherapy. In the 3D group, 159 (62.8%) patients received chemoradiotherapy, 77 with total radiotherapy dose of > 60 Gy, 49 with 50 - 60 Gy. In the 2D group, 127 (46.4%) patients received chemoradiotherapy, 48 with total radiotherapy dose of > 60 Gy, 75 with 50 - 60 Gy.
RESULTSThe 1-, 3-, 5-year overall survival rates (OS) and median survival time for patients treated with 3D-CRT were 73.3%, 26.1%, 14.4% and 20.1 months, respectively, and that of patients treated with 2D radiotherapy were 61.0%, 13.8%, 8.0% and 15.6 months, respectively (P = 0.002). The 1-, 3-, 5-year cause-specific survival rates (CSS) were 79.0%, 33.3%, and 20.8% for the 3D group and 65.1%, 16.7%, 11.2%, respectively, for the 2D group (P = 0.000). The 1-, 3-, and 5-year locoregional control rates were 71.6%, 34.3% and 31.0% for patients treated with 3D radiotherapy and 57.3%, 22.1% and 19.2%, respectively, for patients treated with 2D treatment (P = 0.002). The results of multivariate analysis showed that 3D-CRT, KPS, clinical tumor response and pretreatment hemoglobin level were independently associated with increased OS and CSS. No statistically significant differences were found between the radiation complications in the two groups.
CONCLUSIONSThe results of our study demonstrate that 3D-conformal radiotherapy improves the survival rate in patients with stage III NSCLC compared with that of 2D radiation therapy.
