ObjectiveTo evaluate the value of serum procalcitonin (PCT) level after conventional intravenous antibiotic treatment to predict the risk of re-exacerbation, and vertify the feasiblity of an additional course of oral antibiotics after discharge to reduce the risk of re-exacerbation. MethodsThe patients who hospitalized in West China Hospital from October 2012 to October 2013 because of infectious acute exacerbation of chronic obstructive pulmonary disease (AECOPD) were recruited. The concentrations of PCT and C-reactive protein (CRP), the number of white blood cell (WBC) and neutrophil percentage at the end of intravenous antibiotic therapy were recorded. The information about additional course of antibiotics was collected according to the medical instruction and visit. The subjects were followed up for 1 year.The time to the first re-exacerbation and frequencies of exacerbations were recorded. The Cox regression model was used to estimate the hazard rations (HR). ResultsOne hundred and thirty-eight eligible patients were included totally. The HRs in PCT≥0.11μg/L and neutrophil percentage≥70% were 1.462 (P=0.035) and 1.673 (P=0.005) respectively, suggesting higher risk of re-exacerbation. There was no relationship of CRP (P=0.330) or WBC (P=0.432) with the risk of re-exacerbation. Generally an additional course of antibiotics had no effects on re-exacerbation (P=0.231) but this therapy could reduce the risk of re-exacerbation in high PCT level group (HR=2.29, P=0.004). ConclusionsSerum PCT concentrations and neutrophil percentage after conventional intravenous antibiotic treatment can predict the risk of re-exacerbations in the future. An additional course of antibiotics in the patients with high PCT level can reduce the risk of re-exacerbation.
Objective To discuss the influence of the progress and result in rectal cancer operation through application of neo-adjuvant chemotherapy in multi-disciplinary team (MDT). Methods The patients treated in MDT model and non-MDT model between June to September 2007 were respectively analyzed, and the index about pathologic change, histologic transform and operative result between the two groups were compared.Results In the index of pathologic change, the incidence of abdominal adherence (13.5%, 7/52), ascites (7.7%, 4/52) and latent malignant intestinal obstruction (5.8%, 3/52) in MDT model group were obviously less than non-MDT model group (P=0.000). In the index of histologic transform, texture of mesentery in MDT model group was more fragile than non-MDT model group (P=0.000). The incidence of edema of pelvic tissues in MDT model group were more than non-MDT model group (P=0.000). However, the differences between the incidence of edema of pelvic peritoneum and adherence of mesorectum in two groups were insignificant (Pgt;0.05). In the index of operative results, the operative duration and intra-operative bleeding in MDT model group were less than non-MDT model group (P=0.000). And the protection of pelvic autonomic nerve in MDT model group was better than non-MDT model group (P=0.000). Meanwhile, accuracy rate in prediction of radical resection with anus-preserving in both groups were in high level (92.3% vs 76.2%). Conclusion Neo-adjuvant chemotherapy has certain influence in rectal cancer operation, but the successful operations are performed by standard and correct procedures. Therefore, optimizing combined therapy in MDT model and constructing preoperative evaluation system with neo-adjuvant chemotherapy, would be the next important focus.
【Abstract】Objective Through using neoadjuvant chemotherapy of different circles combined colorectal cancer operations under multi-disciplinary team (MDT), we evaluate effective treatment strategies that suit to colorectal cancer patients in this country. Methods The retrospective study reviewed patients with colorectal cancer treated in general surgery department Ⅲ in West China Hospital of Sichuan University from October 2006 to April 2007. According to the circle times of neoadjuvant chemotherapy, the patients were divided into single-circle group, double-circle group and triple-circle group. And comparing the difference of treatment time, effect index of neoadjuvant chemotherapy and operative results used these stratagies. Results The difference between the time from the end of neoadjuvant chemotherapy to the operation in three groups had no statistical significance （Pgt;0.05）, which were （5.64±2.00） d in single-circle group, (5.80±3.74） d in double-circle group, （6.22±2.76） d in triple-circle group. According to the treatment effects, CEA value decreased during pre- and post-neoadjuvant chemotherapy in each groups （Plt;0.01）. Subjective reception such as hemafecia, anal tenemus and defecation obstruction in double-circle group and triple-circle group were obviously improved than that in single-circle group （Plt;0.01）. Evaluating the tumor condition, the ratio of CR and PR in double-circle group and triple-circle group was higher than that in single-circle group （Plt;0.01）. According to the adverse effect, WBC value of double-circle group and triple-circle group decreased during pre- and post-neoadjuvant chemotherapy, their difference had statistical significance （Plt;0.01）. The difference of WBC pre- and post- neoadjuvant chemotherapy in single-circle group decreased fewer than that in double-circle group and triple-circle group （Plt;0.01）. Nausea and vomit response in triple-circle group were obviously more serious than that in single-circle group and double-circle group （Plt;0.01）. But abdominal distention and diarrhea response had no difference among three groups （Pgt;0.05）. Through our survey, used different neoadjuvant chemotherapy circle, patients in single-circle group and double-circle group were completely accepted within full confidence; but receptance of strategy in triple-circle group was 66.7％(12/18）. All operations were successful. The difference of postoperative aerofluxus time between single-circle group and double-circle group had statistical significance （Plt;0.05）. The difference of postoperative intake time, between triple-circle group and single-circle group, between triple-circle group and double-circle group, had statistical significance （Plt;0.05）. But wound recover time among three groups had no obvious difference （Pgt;0.05）. Conclusion Analyzing neoadjuvant chemotherapy circles, time between neoadjuvant chemotherapy and operation, treatment effect and operation results, it is a feasible and secure colorectal cancer multi-discipinary strategy for patients in West China that choose the treatment of neoadjuvant chemotherapy with double-circle and short preparation time.
Objective To deeply explore the consultation model of multi-disciplinary team (MDT) for colorectal cancer (CRC) reconstruction. Methods After analyzing early consultation model of CRC-MDT, some unreasonable factors were discovered and more suitable model was found. Results With analyzing the problems of members, time and management in early consultation model, reconstructing consultative joints and links, and optimizing flow-sheet were choosed. Finally, the MDT project was set up inter-project clinical round and network consultation. Conclusion The feedback from patients after consultation model reconstruction shows good results. Total consultative system in CRC-MDT will be completely finished step by step. However, advanced researches are still needed.
Objective To further discuss the strategies for building the framework of team culture of multi-disciplinary team (MDT) for colorectal cancer. Methods By analyzing the present situation of volunteer team of MDT and exploring the problems existed, look for new strategies to develop the volunteer team. Results The new strategies, such as optimizing the framework of the volunteer team and introducing into systematic and standardized training program, together with the gradually enlarged propaganda for the volunteer team, promote the development of MDT effectively. Conclusion By the exploration and practice in early stage, the volunteer team of MDT is gradually working smoothly. It is necessary to improve the strategies for developing the volunteer team of MDT constantly to make it integrate the MDT.
