目的探讨腹腔热灌注化疗(HIPEC)在非根治性阑尾来源低级别腹膜假黏液瘤(PMP)中的应用价值。方法回顾性分析300例非根治性阑尾来源低级别PMP患者的临床资料,分析其预后影响因素及HIPEC对其治疗价值。结果237例接受术中HIPEC治疗的患者10年生存率显著高于未接受HIPEC治疗的患者(52%vs.26%,P<0.001);同时接受术中及术后HIPEC治疗的患者10年生存率显著高于单纯接受术中HIPEC治疗的患者(57%vs.44%,P=0.004)。单因素分析显示HIPEC、根治程度、减瘤前PCI>30、减瘤后PCI>30、CA19-9异常为预后影响因素。多因素分析结果提示未接受术中HIPEC治疗以及CA125异常为预后不良的独立危险因素。结论对于无法达到完全减瘤的阑尾来源低级别PMP患者,姑息性减瘤术联合HIPEC治疗仍可显著改善远期预后。 相似文献

A case of pseudomyxoma peritonei that was first recognized bydyspnea and abnormal shadows on chest X-ray film is reported.The patient is a 67-yr-old woman who was found to have an abnormalshadow on chest X-ray filni on routine physical examinationwhen she was 47 yr old (1960). She had been asymptoniatic untilabout 2 yr before admission when she began to experience dyspneawith increased severity. On admission, the chest X-ray filmand com puted tomography showed bilateral pleural thickening.Drainage and decortica tion was carried out, and multiple cystsfilled with a gelatinous substance were found bilaterally inthe thoracic cavity. On the 66th hospital day, pan- peritonitisfollowing perforation of the appendix occurred and an emergencyoperation was performed. The patient died of acute renal failureon the 13th postoperative day. Pseudomyxoma peritonei originatingfrom pseudomucinous cystadenocarcinoma of the appendix was diagnosedon the basis of the findings of the histopathological examination.At autopsy, the gelatinous substance was found in both pleuralcavities, the right subphrenic area, and part of the large omentum.The case presented here is a very rare case of pseudomyxoniaperitonei, because dyspnea was the main feature and abdominalsymptoms such as abdominal distension and pain were lacking.Then high level of serum carcinoenibryonic antigen seen in thiscase is also pointed out. 相似文献

Pseudomyxoma peritonei (PMP) is a rare clinical syndrome. It originates from neoplasms of the appendix and leads to the formation of peritoneal implants and the accumulation of mucinous ascites. PMP represents a spectrum of low to high-grade disease. Despite aggressive management, many PMP patients recur, leading to debilitating symptoms and few treatment options. Therefore, scientists have continued to look for ways to improve treatment and further understand disease pathogenesis. Microorganisms were previously hypothesized to play a role in PMP progression and development. Hence, antibacterial treatment was suggested by some authors, but the data were limited. In this paper, we review the current data on the role of bacteria in PMP, discuss the significance, and suggest possible solutions to the inherent challenges in these studies. Given the limitations of the discussed studies, we remain skeptical about introducing novel antibacterial treatment into clinical practice at this time; however, the available data are valuable and indicate that more research into the molecular mechanisms of PMP is needed. 相似文献

Introduction
For the 3 histologic subtypes of malignant pleural mesothelioma (MPM)—epithelioid, sarcomatoid, and biphasic—the magnitude of benefit with surgical management remains underdefined.Materials and Methods
The National Cancer Data Base was queried for newly diagnosed nonmetastatic MPM with known histology. Patients in each histologic group were dichotomized into those receiving gross macroscopic resection versus lack thereof/no surgery. Kaplan-Meier analysis evaluated overall survival (OS) between cohorts; multivariable Cox proportional hazards modeling assessed factors associated with OS. After propensity matching, survival was evaluated for each histologic subtype with and without surgery.Results
Overall, 4207 patients (68% epithelioid, 18% sarcomatoid, 13% biphasic) met the study criteria. Before propensity matching, patients with epithelioid disease experienced the highest median OS (14.4 months), followed by biphasic (9.5 months) and sarcomatoid (5.3 months) disease; this also persisted after propensity matching (P < .001). After propensity matching, surgery was associated with significantly improved OS for epithelioid (20.9 vs. 14.7 months, P < .001) and biphasic (14.5 vs. 8.8 months, P = .013) but not sarcomatoid (11.2 vs. 6.5 months, P = .140) disease. On multivariable analysis, factors predictive of poorer OS included advanced age, male gender, uninsured status, urban residence, treatment at community centers, and T4/N2 disease (all P < .05). Chemotherapy and surgery were independently associated with improved OS, as was histology (all P < .001).Conclusion
This large investigation evaluated surgical practice patterns and survival by histology for MPM and found that histology independently affects survival. Gross macroscopic resection is associated with significantly increased survival in epithelioid and biphasic, but not sarcomatoid, disease. However, the decision to perform surgery should continue to be individualized in light of available randomized data. 相似文献17.
目的:探讨手术切除联合化疗对晚期结肠癌肝转移患者生存状况的影响。方法选择晚期结肠癌肝转移患者102例,将采用手术切除联合化疗的35例患者纳入观察组,将单纯采用化疗的67患者纳入对照组。随访3年,观察两组患者治疗开始至肿瘤病灶进展的时间( TTP),化疗过程中出现的不良反应,对比两组患者的1、2、3年累积生存率。结果观察组患者共化疗160个疗程,平均4.57个疗程,TTP为14个月;对照组患者共化疗359个疗程,平均5.35个疗程,TTP为8个月,两组之间差异有统计学意义(P<0.05)。观察组患者贫血发生率显著高于对照组(P<0.05),其余不良反应发生率差异无统计学意义(P>0.05)。观察组中位生存时间为26.5个月,对照组中位生存时间为22.7个月,差异有统计学意义(P<0.05)。观察组1、2、3年生存率分别为88.6%,57.1%和42.9%;对照组1、2、3年生存率分别为71.6%,44.8%和34.3%。其中1年生存率两组之间差异显著(P<0.05),2、3年生存率两组之间的差异无统计学意义(P>0.05)。结论手术联合化疗治疗晚期结肠癌肝转移患者不会增加化疗的不良反应,可以提高患者的疗效和生存率。有手术指征的晚期结肠癌肝转移患者应积极采取手术治疗。 相似文献

Two cases of pseudomyxoma peritonei with high serum carcinoembryonicantigen (CEA) are reported. CEA levels in serum increased incorrelation with the accumulation of ascites. Systemic chemotherapywith anticancer agents such as 5-fluorouraciI (5-FU), cyclophosphamide,mitomycin C (MMC) and chromomycin Aa showed no effect on reducingeither the production of mucinous materials or the CEA level,but repeated intraperi-toneal instillation of large amountsof MMC reduced them in one case. In the other case, the CEAlevel returned to normal after removal of the tumor. These resultssuggest that CEA may be a useful indicator of the effect oftreatment and of the prognosis of pseudomyxoma peritonei. 相似文献
