Objective To compare the clinical effect between neo-adjuvant chemotherapy combined with operation and simple operation under multi-disciplinary team in rectal cancer. Methods A survey of 72 patients with rectal cancer from Nov. 2007 to Mar. 2008 were studied. Patients were divided into two groups using a simple random method: 33 cases in combined therapy group were treated with single period neo-adjuvant chemotherapy as well as operation and 39 cases in control group received operation only. To compare the differences of perioperative period indexes between two groups. Results During the differences of indexes of age, gender, differentiation degree, clinicopathologic stage as well as the distance to dentate line of tumor, there was no statistical significance between combined therapy group and control group (Pgt;0.05). And at the same time, the operative type, operative time and bleeding quantity in operation had no statistically significant difference between two groups (Pgt;0.05). As for the postoperative rehabilitation indexes, the time of vent to normal in combined therapy group was earlier than that in control group, but the intake time was later than that in control group （Plt;0.05）. Falling range from preoperative CEA to postoperative CEA was larger in combined therapy group than that in control group （Plt;0.05）; and the falling range from preoperative WBC to postoperative WBC had no significant difference between two groups （Pgt;0.05）. Conclusion The clinical effect of combined therapy is obviously superior to simple operation, suggesting that neo-adjuvant chemotherapy combined with operation is feasible and safe.
Objective To discuss the safety and clinical differences among elderly people being treated with neo-adjuvant chemotherapy combined with operation. Methods To analyze retrospectively the data of patients diagnosed definitely as colorectal cancer in West China Hospital of Sichuan University from June 2007 to December 2007, and to compare the clinical effect differences between elderly group (≥60 years) and non-elderly group (lt;60 years) with combined therapy. Results Among preoperative indexes, the constituent ratios of elderly group combined with cardiac vessels system diseases, endocrine system diseases or other system diseases were all obviously higher than those of non-elderly group, the differences showed statistical significance (Plt;0.05); Constituent ratio of elderly patients with hypertension or diabetes mellitus was also higher than that of non-elderly patients, there were still statistical significance (Plt;0.05), but no statistical significances among other preoperative indexes (Pgt;0.05); Differences of indexes during operation between two groups showed no statistical significance (Pgt;0.05). But during postoperative indexes, complications in elderly group were higher than those of non-elderly group, and the differences had statistical significance (Plt;0.05), and the time of removing gastric canal, urinary catheter and drainage tube between two groups showed no statistical significance (Pgt;0.05); Meanwhile, the intake time, venting time and defecation time after operation and out-of-bed activity time after operation also had no statistical significance (Pgt;0.05). As to the adverse effect relate to chemotherapy, there were no statistical significances (Pgt;0.05). Conclusion Elderly patients may have more poor physical condition and it maybe more difficult to treat them. In spite of this, the comprehensive treatment of neo-adjuvant chemotherapy combined with surgical operation will not lead to the delay of surgical therapy, in addition, operating modus during surgical intervention will not be effected and its therapeutic effect in the near future was optimistic. So the application of this combined therapy has some clinical effects and would be safety.
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.
Objective To explore the clinical effect of different strategies for surgical treatment of cancer of rectum combined with neo-adjuvant chemotherapy under multi-disciplinary team. Methods From January 2007 to December 2007, the patients diagnosed definitely as rectal cancer were analyzed retrospectively, of whom accept surgery combined with neo-adjuvant chemotherapy were included. The clinical effects were studied and observed, the differences among the strategies for different surgical treatment 〔high anterior resection (HAR), low anterior resection (LAR), out-pouching with colo-anal anastomosis (OCAA), radical resection with non-saving anus (RNSA), and palliation colostomy (PCO)〕 in the multi modality therapy were compared. Results Comparing the constituent ratio of gross type of tumor in five groups, the difference between PCO group and the other 4 groups had mainly statistical significance （P＜0.05）. The difference of constituent ratio of Dukes staging had statistical significance between HAR group and OCAA group, HAR group and PCO group, LAR group and PCO group （P＜0.05）. According to the duration of operation, the persisting time of PCO group was obviously shorter than that of the other 4 groups （P＜0.05）, meanwhile, the persisting time of LAR group was shorter than that of OCAA group and RNSA group （P＜0.05）. According to the volume of ascites discovered in operation, mainly between HAR group and LAR group, between HAR group and RNSA group, the incidence of a seroperitoneum more than 200 ml in the former was less than the latter （P＜0.05）. Regarding to indexes of laboratory, CEA value in PCO group was higher than the other 4 groups, serum amyloid A value in RNSA group was higher than the other 4 groups, and the differences had statistical significances （P＜0.05）. Conclusion Mini-invasive surgery may have certain significance in clinical effect of the comprehensive treatment for advanced rectal cancer when different operative methods were combined with neo-adjuvant chemotherapy. And by the way, better clinical effect will take place when the anus-retained operation is possibly performed.
Objective To explore the intervention effect on colorectal cancer operation by neo-adjuvant chemotherapy in multi-disciplinary team. Methods To analyze retrospectively the data of patients diagnosed definitely as colorectal cancer in the West China Hospital of Sichuan University from July 2007 to December 2007, and the planned and actual operative strategy were compared between MDT group and non-MDT group. Results According to the inclusion criteria, 251 colorectal cancer patients were included which had 183 rectal cancer and 68 colon cancer. The baseline between MDT group and non-MDT group was equal, and there was no difference of planned operative strategy between two groups. For patients planned undergoing standard ano-saving radical procedure, the ratio of actual procedure same to the planned and the ratio of radical procedure changed to expansive ano-saving radical procedure showed no significant differences between MDT group and non-MDT group (Pgt;0.05), whereas the difference of the ratio of radical procedure changed to local radical procedure between two groups was statistically significant (Plt;0.01). And the constituent ratio of actual procedure between two groups for patients which planned accepted non-ano-saving procedure didn’t have any significant difference (Pgt;0.05). For the cancer focus, the relief differences of complete remission and partial remission were statistically significant between two groups (P＜0.01), but the difference of the constituent ratio of T staging change was not statistically significant (Pgt;0.05). Conclusion The value of neo-adjuvant chemotherapy should not be limited to decrease the stage of cancer, and it is important to pay more attention to the high quality of combined therapy. Further research should be carried out to find the contribution of neo-adjuvant chemotherapy to mini-invasive surgery.
Objective To explore the clinical effect of neo-adjuvant/adjuvant chemotherapy combined with operation on colorectal cancer patients in the multi-disciplinary team (MDT). Methods The data were collected retrospectively from January to December in 2007. The patients were classified as non-adjuvant chemotherapy group and adjuvant chemotherapy group according to the treatment strategy. Non-adjuvant chemotherapy group had accepted only surgery followed by preoperative neo-adjuvant chemotherapy, and adjuvant chemotherapy group had taken postoperative adjuvant chemotherapy after preoperative neo-adjuvant chemotherapy and operation. The clinical effect of two groups were compared. Results Totally 789 patients were treated among 2007, and 195 patients who were firstly diagnosed as colorectal cancer were included, and there were 109 males and 86 females, 59 colonic cancers and 136 rectal cancers. Average age was 59.98 years old. All of the included patients were followed up for 5-17 months. Three cases missed, no recurrence and no death happened. The baseline between non-adjuvant chemotherapy and adjuvant chemotherapy group was nearly same. There were no differences between two groups about the internal medicine complications, the cancer related obstruction, preoperative transfusion or not (P＞0.05). Whether the patients were transfused or not during the procedure and Dukes stage were significantly different between two groups(P＜0.05), while the other surgical and pathological index didnt show any statistical significance (P＞0.05). After operation, more patients in non-adjuvant chemotherapy group had accepted transfusion (P＜0.05). However, the postoperative rehabilitative indexes during hospitalization were not different between two groups. And the differences about the postoperative complications and defecation were not significant (P＞0.05). The values of CEA and CA19-9 were greatly different between two groups in the 1st and 3rd month follow-up. Conclusion The strategy of neo-adjuvant chemotherapy/operation/adjuvant chemotherapy didnt affect the rehabilitation and increase the risk of complications, however, more researches were necessary to prove whether the clinical effect were improved or not.
Objective To explore the quality of life of colorectal cancer patients undergoing multi-disciplinary comprehensive treatment by neo-adjuvant chemotherapy combined with radical resection. Methods From May 2007 to August 2007, the patients diagnosed definitely as colorectal cancer were analyzed retrospectively, of whom accepted neo-adjuvant chemotherapy combined with surgery were included and evaluated by quality of life questionnaire-core 30 (QLQ-C30) of European Organization for Research and Treatment of Cancer (EORTC), and there were 3 time points chosen for assessment which were pre-neoadjuvant chemotherapy stage (point A), preoperative stage after neo-adjuvant chemotherapy (point B), and one month after surgery (point C). Results A total of 57 patients with an average age of 56.33 years (41-69 years) were incorporated in this study, and among which there were 34 male and 23 female; and 10 right-sided hemi-colonic cancer, 4 left sided hemi-colonic cancer, 43 rectal cancer. The global health differences between the A and B point or A and C point were statistically significant (Plt;0.001) whereas no significant difference existed between B and C point (Pgt;0.05). For the functioning scales of physical, physical, role, cognitive, and social function, no statistically difference among A, B and C time point. Although there wasn’t any emotional difference existed between A and B point (Pgt;0.05), obvious differ between C and A or C and B point were showed out (Plt;0.005). And for symptom scales, no remarkable differences came out among A, B and C point for dyspnoea and constipation (Pgt;0.05); reversely, great differences were found for fatigue, pain, insomnia, appetite loss, and diarrhoea between C and A or C and B point (Plt;0.01), but nope for A and B in the 5 items of symptom (Pgt;0.05). And the score of nausea and vomiting presented significantly differences between A and B or B and C point (Plt;0.01), but nope for A and C in this item (Pgt;0.05). There came out distinct significantly for financial impact among A, B and C point with a worsen score from early to late stage (Plt;0.001). Conclusion The intervention of chemotherapy could worsen the quality of life during the treatment of neo-adjuvant chemotherapy combined with surgery which may be attributed to the side reaction, but such adverse reaction may not affect actually the postoperative subjective feeling; On the other hand, the colorectal surgery may not decrease the quality of life although which could lead more early postoperative uncomforting. However, it needs more researches to discuss about the contribution of different comprehensive treatment strategy to the quality of life as well as the cost-effective analysis.
Objective To evaluate the risk of management decision combined neo-adjuvant chemotherapy with operation for colorectal cancer by means of the colorectal cancer model of the Association of Coloproctology of Great Britain and Ireland (ACPGBI-CCM). Methods One hundred and eighty-one eligible patients (102 male, 79 female, mean age 58.78 years), which were pathologically proved colorectal cancer in our ward from July to November 2007, involved 62 colonic and 119 rectal cancer. The enrollment were assigned into multi-disciplinary team (MDT) group (n=65) or non-MDT group (n=116), according to whether the MDT was adopted, and the operative risk was analyzed by ACPGBI-CCM. Results The baseline characteristics of MDT and non-MDT group were coherent. The watershed of lower risk group (LRG) and higher risk group (HRG) was set as predictive mortality=2.07%. The time involving extraction of gastric, urethral and drainage tube, feeding, out-of-bed activity after operation in MDT group, whatever in LRG or HRG, were statistically earlier than those in non-MDT group (P＜0.05). The resectable rate in LRG was statistically higher than that in HRG (P＜0.05), and the proportion of Dukes staging was significantly different (P＜0.05) between two groups; Moreover, predictive mortality in HRG was statistically higher than that in LRG (P＜0.05), while actually there was no death in both groups. Conclusion Dukes staging which is included as an indispensable option by ACPGBI-CCM is responsible for the lower predictive mortality in LRG.Hence, the value of ACPGBI-CCM used to asses the morbidity of complications within 30 days postoperatively would be warranted by further research. The postoperative risk evaluation can serve as a novel routine to comprehensively analyze the short-term safe in the MDT.
Objective To investigate the efficacy and safety of neo-adjuvant chemotherapy for stage ⅠB2-ⅡB cervical cancer. Methods From June 2012 to December 2014, 66 patients with stage ⅠB2-ⅡB cervical cancer were selected and treated by PT (cisplatin/ carboplatin and taxol/docetaxel) as neo-adjuvant chemotherapy prior to surgery. Neo-adjuvant chemotherapy response and toxicity were collected and analyzed. Results The extinctive condition of tumor by neo-adjuvant chemotherapy: the complete remission rate was 10.6% (7/66), partial remission rate was 59.1% (39/66), and the total effective rate was 69.7%. The main toxicities were myelosuppression (59.1%, 39/66) and gastrointestinal reactions (33.3%, 22/66). The toxicities could be tolerated or relieved by prevention and treatment. The effective rate of chemotherapy for cervical squamous cell carcinoma, adenocarcinoma, adenosquamous carcinoma was 72.6%, 33.3% and 0%, respectively, with significant differences among the three types (P<0.05). The effective rate of chemotherapy for high, medium and low differentiated cervical cancer was 100.0%, 77.3% and 55.9%, respectively, with significant differences among the three degrees (P<0.05). Conclusions Neo-adjuvant chemotherapy is proved to be a safe and effective complementary treatment for most patients with locally advanced cervical cancer. Due to the limitation of sample size, the correlations between therapeutic effect and tumor differentiation degree and between therapeutic effect and pathological type need further study.
