Fluoropyrimidines have been the standard care as ajuvant or palliative treatment for malignant gastrointestinal carcinoma over several decades. Their common adverse effects include gastrointestinal effects, myelosuppression, and hand-foot syndrome. Besides, fluoropyrimidines are the second cause of chemotherapy-induced cardiotoxicity and have the different manifestation and machanisms from anthracyclines. With the development of onco-cardiology, increasing concern is raised on fluoropyrimidine-induced cardiotoxicity. This review addresses the epidemiology, clinical manifestation, and proposed mechanisms; and also highlights the diagnosis, monitoring and management of fluoropyrimidine-induced cardiotoxicity.
This study aims to investigate the value of pre-treatment computed tomography (CT) texture analysis in predicting therapeutic response of liver metastasis from colorectal cancer after combined targeting chemotherapy. A total of 82 patients with colorectal cancer liver metastases who underwent chemotherapy combined with targeted therapy (cetuximab) between March 2011 and October 2017 comprised this retrospective study population. According to the RECIST1.1, the best curative effect evaluation of patients was recorded. Complete response (CR) and partial response (PR) were assigned to the response group, and the stable disease (SD) and progressive disease (PD) were assigned to the non-response group. The CT texture analysis was based on the Omini-Kinetics software, and the three-dimensional (3D) texture analysis was performed on the marked lesion on portal phase. The differences of texture parameters between the response group and the non-response group were compared. The receiver operating characteristic (ROC) curves were depicted on the parameters which with statistically difference, to characterize value in predicting the response to target-combined chemotherapy. The differences of Entropy, Energy, Variance, std. Deviation, Quantile95 and sumEntropy between the two groups in pre-treatment lesions were significant (P < 0.05). And lesions with higher Entropy, lower Energy, higher Variance, higher std Deviation and higher sumEntropy seemed to indicate a better therapeutic response. When sumEntropy > 0.867, good diagnostic efficiency could be obtained, with sensitivity of 60.5% and specificity of 79.5%, respectively. In conclusion, texture parameters derived from baseline CT images of colorectal cancer liver metastasis have the potential value acting as imaging biomarkers in predicting tumor response to combined target chemotherapy.
Chemotherapy-induced mucositis, one of the most common complications of chemotherapy, can be subdivided in oral and gastrointestinal mucositis. The patients always suffer from oral pain and ulcers, nausea, vomiting, abdominal pain and diarrhea. 5-Fluorouracil- and irinotecan-based regimens are frequently associated with a higher risk and more severe grade of mucositis. The onset of mucositis is also influenced by the patient’s characteristics including age, sex, genetic polymorphisms, systemic comorbidities. At present, the diagnosis of chemotherapy-induced mucositis is mainly based on medical history, physical examination and gastroenteroscopy, lack of reliable biomarkers for early diagnosis. The principles of diagnosis and treatment mainly refer to the clinical practice guidelines issued. Therefore, this article will review the mechanism, diagnosis, latest preventive and treatment strategies of chemotherapy-induced mucositis for helping clinicians to further correctly understand and deal with the adverse reactions.
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.
【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 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 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.
