Objective To determine the influence of combinative assessment of 64 multi-slice spiral computer tomography (MSCT) and serum amyloid A protein (SAA) on the selection of operative procedures of upper rectal cancer in multi-disciplinary team. Methods Prospectively enrolled 110 patients, who were diagnosed definitely as upper rectal cancer (distance of tumor to the dentate line gt;7 cm) at West China Hospital of Sichuan University from August 2007 to October 2008, randomly assigned into two groups. In one group named MSCT+SAA group, both MSCT and SAA combinative assessment were made for the preoperative evaluation. In another group named MSCT group, only MSCT was made preoperatively. Then, the pooled data were analyzed for the correlative relationship between the choice of surgery strategy and clinicopathologic factors. Furthermore, the preoperative staging and predicted operative procedures were compared with postoperative pathologic staging and practical operative procedures, respectively. Results According to the criteria, 106 patients with upper rectal cancer were randomly assigned into MSCT+SAA group (n=52) and MSCT group (n=54). The baseline characteristics of two groups were statistically identical. When analyzing the proportion of multiple clinicopathologic factors in different operative procedures of upper rectal cancer, there were statistical differences in the preoperative N staging (P=0.003), M staging (P=0.022), TNM staging (P=0.003), serum level of SAA (P=0.005) and general category of tumor (P=0.027). For MSCT+SAA group the accuracies of preoperative staging T, N, M and TNM were 84.6%, 86.5%, 100% and 86.5%, respectively; For MSCT group the corresponding rates were 83.3%, 2.9%, 100% and 64.8%, respectively. There were statistically significant differences accuracies of preoperative N staging and TNM staging (P=0.005, P=0.009, respectively) in two groups. There was a statistically significant difference of the accuracy of prediction to operative procedures in two groups (96.2% vs. 81.5%, P=0.017). Conclusion Combinative assessment of 64 MSCT and SAA could improve the accuracy of preoperative staging, and thus provide higher predictive coincidence rate to operative procedures for surgeon.
A 55-year-old male patient was admitted to the hospital due to "recurrent chest pain for 8 months, with worsening symptoms for 2 weeks". After admission, comprehensive relevant examinations led to the consideration of a giant chronic left ventricular pseudoaneurysm caused by myocardial infarction with non-obstructive coronary arteries. Surgical treatment was performed at our hospital. We discuss the diagnosis and treatment of this patient.
Preoperative evaluation is crucial for heart valvular surgery. This article discusses some issues that need to be emphasized: the impact of hypertension on the severity of aortic valve lesions, and how to improve the accuracy of clinical assessment; the identification of functional tricuspid regurgitation, in order to choose the appropriate surgical technique; the need for right ventricular function testing, and the use of risk scoring models, to better grasp surgical timing and indications and improve efficacy; and the importance of evaluating atrial mitral and/or tricuspid regurgitation complications in chronic atrial fibrillation, and making rational choices for interventional and surgical treatment.
Objective To determine the relationship between preoperative prognostic inflammatory and nutritional index (PINI) value and short-term prognosis in colorectal cancer. Methods Patients with colorectal cancer verified by pathologically examine were prospectively enrolled from April 2009 to June 2009. Serum alpha-1-acid glycoprotein, C-reactive protein, albumin and prealbumin were examined on day 3 before operation, and the value of preoperative PINI was calculated. The relationships between preoperative PINI and patho-TNM stage, complications, quality of life, and recurrence and metastasis after operation were analyzed. Results Total 38 patients with colorectal cancer underwent radical surgery were enrolled. Preoperative PINI value was 2.17±1.27. Preoperative PINI value was correlated with TMN stage and M stage: PINI value in patients of Ⅳ stage or M1 stage, were significantly higher than those in ones of Ⅰ, Ⅱ and Ⅲ stage （P＜0.001） or M0 stage （P＜0.001）. There was no significant correlation between preoperative PINI value and preoperative complications （Pgt;0.05）. Preoperative PINI value was correlated with postoperative diet, anorexia and overall quality of life: preoperative PINI value in patients with abnormal diet, anorexia or poor quality of life, were significantly higher than those in ones with normal diet (P=0.020), no-anorexia (P=0.020) or moderate (P=0.025) and well (P=0.020) quality of life. Conclusion Preoperative PINI value is an effective index to assess the short-term prognosis of colorectal cancer.
Objective To determine the influence and significance of combinative assessment of 64 multi-slice spiral computed tomography (MSCT) with serum amyloid A protein (SAA) or C-reactive protein (CRP) on the selection of operative procedures of rectal cancer under the multi-disciplinary team. Methods Prospectively enrolled patients diagnosed definitely as rectal cancer at West China Hospital of Sichuan University from February to August 2009 were randomly assigned into two groups. In one group named MSCT+SAA group, both 64 MSCT and SAA combinative assessment were made for the preoperative evaluation. In another group named MSCT+CRP group, both MSCT and CRP combinative assessment were made for preoperative evaluation. Furthermore, the preoperative staging and predicted operation procedures were compared with postoperative pathologic staging and practical operation procedures, respectively, and the relationship between the choice of operation procedures and clinicopathologic factors was analyzed. Results All 165 patients were randomly assigned into MSCT+SAA group (n=83) and MSCT+CRP group (n=82). The baseline characteristics of two groups were statistically similar (Pgt;0.05). For MSCT+SAA group, the accuracies of preoperative staging T, N, M and TNM were 74.7%， 68.7%, 100% and 66.3%, respectively. For MSCT+CRP group, the accuracies of preoperative staging T, N, M and TNM were 72.0%, 86.6%, 100% and 81.7%, respectively. There were statistically significant differences in the accuracies of N staging and TNM staging between two groups (P＜0.05). However, there was no statistically significant difference of the accuracy of prediction to operative procedures between two groups (90.4% vs. 95.1%, Pgt;0.05). The pathological T staging (P＜0.001), N staging (P＜0.001), TNM staging (P＜0.001), preoperative serum level of SAA (P=0.010), serum level of CRP (P=0.042), and distance of tumor to the dentate line (P=0.011) were associated with the operative procedures. Conclusion Combinative assessment of MSCT+CRP could improve the accuracy of preoperative staging and operative procedures prediction, which may be superior to MSCT+SAA.
Objective To summarize the progress in diagnosis and treatment of hilar cholangiocarcinoma at present. Methods The literatures about diagnosis and treatment of hilar cholangiocarcinoma at home and aboard were collected to make an review. Results The diagnosis of hilar cholangiocarcinoma mainly depended on serum tumor molecular markers and imaging examinations. Preoperative excision and prognostic evaluation were required, including tumor classification and staging, preoperative yellow reduction, residual liver volume assessment, and so on. Radical resection was the first choice, as well as liver transplantation, radiotherapy, chemotherapy, and photodynamic therapy could be selected according to the patient’s condition. Conclusions The appearance of new diagnosis and treatment technology promotes the clinical development of hilar cholangiocarcinoma. The integrated diagnosis and treatment mode, which is based on surgery, will become the inevitable direction of the development of hilar cholangiocarcinoma.
Objective To investigate the relationship of serum amyloid A protein (SAA) and surgical choice in low locally advanced rectal cancer (LLARC). Methods Fifty-two patients with LLARC at West China Hospital of Sichuan University were retrospectively analyzed. According to operative methods the patients were divided into 2 groups: curative surgery group (n=35) and palliative surgery group (n=17). Then, venous blood specimens were taken to measure preoperative serum SAA level. Results The analysis showed the option of surgical procedures was associated with preoperative SAA concentration (P=0.004) in LLARC, but irrelative with pathological characteristics and preoperative imaginologic staging (Pgt;0.05). High concentration of serum SAA (≥10.5 mg/L) significantly increased the odds of palliative surgery 〔OR=7.47, 95% CI (1.62-34.40), P＝0.010〕.Conclusion High level of SAA is a useful marker to predict the possibility of palliative surgery in LLARC, which is helpful to screen the patients for the surgical decision and adjuvant therapy.
