OBJECTIVE: The aim of this study was to determine whether aggressive management of neuroendocrine hepatic metastases improves survival. SUMMARY BACKGROUND DATA: Survival in patients with carcinoid and pancreatic neuroendocrine tumors is significantly better than adenocarcinomas arising from the same organs. However, survival and quality of life are diminished in patients with neuroendocrine hepatic metastases. In recent years, aggressive treatment of hepatic neuroendocrine tumors has been shown to relieve symptoms. Minimal data are available, however, to document improved survival with this approach. METHODS: The records of patients with carcinoid (n = 84) and pancreatic neuroendocrine tumors (n = 69) managed at our institution from January 1990 through July 2004 were reviewed. Eighty-four patients had malignant tumors, and hepatic metastases were present in 60 of these patients. Of these 60 patients, 23 received no aggressive treatment of their liver metastases, 19 were treated with hepatic resection and/or ablation, and 18 were managed with transarterial chemoembolization (TACE) frequently (n = 11) in addition to resection and/or ablation. These groups did not differ with respect to age, gender, tumor type, or extent of liver involvement. RESULTS: Median and 5-year survival were 20 months and 25% for the Nonaggressive group, >96 months and 72% for the Resection/Ablation group, and 50 months and 50% for the TACE group. The survival for the Resection/Ablation and the TACE groups was significantly better (P < 0.05) when compared with the Nonaggressive group. Patients with more than 50% liver involvement had a poor outcome (P < 0.001). CONCLUSIONS: These data suggest that aggressive management of neuroendocrine hepatic metastases does improve survival, that chemoembolization increases the patient population eligible for this strategy, and that patients with more than 50% liver involvement may not benefit from an aggressive approach. 相似文献

Purpose To assess the outcome and prognostic factors of liver surgery for breast cancer metastasis.
Methods We retrospectively examined 16 patients who underwent partial liver resection for breast cancer liver metastasis (BCLM). All
patients had been treated with chemotherapy or hormonotherapy, or both, before referral for surgery. We confirmed by preoperative
radiological examinations that metastasis was confined to the liver. The survival curve was estimated using the Kaplan-Meier
method. Univariate and multivariate analysis were conducted to evaluate the role of the known factors of breast cancer survival.
Results The median age of the patients was 54 years (range 38–68) and the median disease-free interval between the diagnoses of breast
cancer and liver metastasis was 54 months (range 7–120). Nine major and 7 minor hepatectomies were performed. There was no
postoperative death. The overall 1-, 3-, and 5-year survival rates were 94%, 61%, and 33%, respectively. The median survival
rate was 42 months. Univariate analysis revealed that hormone receptor status, number of metastases, a major hepatectomy,
and a younger age were associated with a poorer prognosis. The survival rate was not influenced by the disease-free interval,
grade or stage of breast cancer, or intraoperative blood transfusions. The number of liver metastases was identified as a
significant independent factor of survival according to the Cox proportional hazard model (P = 0.04).
Conclusions Liver resection, when done in combination with adjuvant therapy, can improve the prognosis of selected patients with BCLM. 相似文献

Does complete resection of melanoma metastatic to solid intra-abdominal organs improve survival? 总被引:1,自引:2,他引:1

Background:Patients with distant melanoma metastases have median survivals of 4 to 8 months. Previous studies have demonstrated improved survival after complete resection of pulmonary and hollow viscus gastrointestinal metastases. We hypothesized that patients with metastatic disease to intra-abdominal solid organs might also benefit from complete surgical resection.Methods:A prospectively acquired database identified patients treated for melanoma metastatic to the liver, pancreas, spleen, adrenal glands, or a combination of these from 1971 to 2010434_2001_Article_658. The primary intervention was complete or incomplete surgical resection of intra-abdominal solid-organ metastases, and the main outcome measure was postoperative overall survival (OS). Disease-free survival (DFS) was a secondary outcome measure.Results:Sixty patients underwent adrenalectomy, hepatectomy, splenectomy, or pancreatectomy. Median OS was significantly improved after complete versus incomplete resections, but median OS after complete resection was not significantly different for single-site versus synchronous multisite metastases. The 5-year survival in the group after complete resection was 24%, whereas in the incomplete resection group, there were no 5-year survivors. Median DFS after complete resection was 15 months. Of note, the 2-year DFS after complete resection was 53% for synchronous multi-site metastases versus 26% for single-site metastases.Conclusions:In highly selected patients with melanoma metastatic to intra-abdominal solid organs, aggressive attempts at complete surgical resection may improve OS. It is important that the number of metastatic sites does not seem to affect the OS after complete resection. 相似文献

BackgroundThe ETR that should be undertaken in patients with GBM remains controversial. This study aims to reiterate some independent predicting factors and to underscore the role and the ETR in increasing the survival of patients in the situation of developing countries, that is, without preoperative MRI or tractography. The authors submit additional information to be added to the list of CTRs in the management of malignant brain tumors.MethodsThe authors prospectively analyzed a cohort of 35 consecutive patients with histologically proven GBM who underwent tumor resection in surgically amenable areas for the first time at Sina Hospital, Tehran, between 2003 and 2005. Demographic data, volumetric measurements, and other characteristics identified on preoperative and immediate postoperative MR imaging as well as intraoperative and postoperative clinical data were collectively analyzed by SPSS for Windows, version 11.5 (SPSS, Chicago, Ill).ResultsCox proportional hazards model multivariate analysis identified the following independent predictors of survival: Karnofsky performance scale ≥80 (P = .01), ETR (P = .01), tumor location in functionally silent prefrontal area (P = .002) vs tumor location in corpus callosum (P = .001), postoperative RT (P = .004), and postoperative chemotherapy (P = .001)ConclusionMaximal resection of the tumor volume is an independent variable associated with longer survival times in patient with GBM. Gross total resection should be performed whenever possible, although not at the expense of increased morbidity. 相似文献

BACKGROUND: The clinical outcome of patients with ampullary carcinoma is significantly more favorable than for patients with pancreatic head carcinoma. The Whipple procedure is the operation of choice for both diagnoses. Still local resection is recommended in selected cases. The aim of this study was to assess the outcome of local resection of cancer of the ampulla of Vater by comparison with pancreaticoduodenectomy. METHOD: 92 patients with cancer of the ampulla of Vater treated between 1975 and 1999 with local resection (n = 10), pancreatic resection (n = 49) or laparotomy and no resection (n = 33) were studied retrospectively. The main outcome measures were postoperative morbidity and mortality, surgical radicality and long-term survival. RESULTS: The postoperative complication rate was significantly lower after local resection (p = 0.036) whereas mortality did not differ between the 2 resection groups. UICC stages were less advanced in the local resection group (p < 0.04). Still, the frequency of positive resection margins and RO resections was the same in both groups, as was long-term survival. Local recurrence was diagnosed in 8/10 (80%) patients after local and in 11/49 (22%) patients after pancreatic resection (p = 0.001). CONCLUSION: Pancreaticoduodenectomy is the preferred operation for cancer of the ampulla of Vater in patients who are fit for the procedure. Local resection plays a limited role in carefully selected patients. 相似文献

A best evidence topic in cardiac surgery was written according to a structured protocol. The question addressed was whether re-operative surgery or radiotherapy should be given to patients with residual microscopic tumour at the bronchial resection margin. Altogether 427 papers were identified using the reported search of which 13 represented the best evidence on this topic. The author, journal, date and country of publication, patient group studied, study type, relevant outcomes, results and study weaknesses were tabulated. We conclude that for patients with stage I-II tumours who could easily tolerate re-operation, further resection is an acceptable treatment option and may improve survival. However, only 4 of the 13 studies that we identified recommend this strategy. In addition, there is no convincing evidence that radiotherapy significantly improves survival for patients not selected for re-operation. 相似文献

Does radical resection improve the survival in patients with carcinoma of the gallbladder who are 75 years old and older? 总被引:2,自引:0,他引:2
Radical resections have been reported to improve the surgical outcome for patients with carcinoma of the gallbladder. In recent years surgeons have had more opportunities to operate on elderly patients. We investigated whether the survival rate of aged patients who had radical resections were better than rates for those who had simple cholecystectomy. Of the 300 patients treated for carcinoma of the gallbladder between 1971 and 1999, 206 resected cases (except pancreaticoduodenectomy and hepatectomy) were divided into two groups: age 75 years or older, 54 patients (the older group), and age less than 75 years, 152 patients (the younger group). Clinical features and progression of the carcinomas did not differ between the two groups. In the older group, 22 patients (40.7%) had simple cholecystectomy, 32 (59.3%) had radical resections; in the younger group, 65 patients (42.8%) had simple cholecystectomy, and 87 (57.3%) had radical resection. None of the older patients who had radical resection died postoperatively. Postoperative survival was not different between the two groups. In the older group the 5-year survival rate for patients who had radical resections was better (60.9%) than the rate for those who had simple cholecystectomy (14.1%) (p = 0.0098). Radical resection is effective for the aged patients with the carcinoma of gallbladder. 相似文献

Aim A poor functional outcome is often reported after total mesorectal excision (TME) for rectal cancer, especially when sphincter‐saving resection with intersphincteric dissection is performed for low tumours. Anal sphincter rehabilitation is widely proposed for faecal incontinence. Very few studies have reported results to improve anal dysfunction following rectal surgery. This prospective study aimed to assess the benefits of sphincter training after TME in terms of functional outcome and quality of life. Methods Anal sphincter training was performed in patients undergoing laparoscopic sphincter‐saving TME for rectal cancer. Rehabilitation was performed after ileostomy closure. This group was compared with 24 matched patients. Assessment included one functional and two quality of life questionnaires (SF‐36 Health Status and Faecal Incontinence Quality of Life score). Results From 2007 to 2009, 22 patients underwent laparoscopic TME. The median follow‐up after stoma closure was 21.2 (range 8–46) months. The mean stool frequency per day was significantly lower after sphincter training (2.6 in the training group vs 4.0 in the control group, P = 0.025). Following rehabilitation, patients complained significantly less about dyschezia (22 vs 63%, P = 0.008). Both groups had similar continence (Wexner score 8.3 after training vs 9.9 in controls, NS). Quality of life was significantly improved by sphincter training as measured by the vitality (P = 0.004) and mental functioning (P = 0.02) subscales on the SF‐36 Health Status questionnaire and by the depression and self‐perception (P = 0.005) categories of the Faecal Incontinence Quality of Life score. Conclusion This study suggests that anal sphincter training following TME could decrease stool frequency and improve both general and specific quality of life. 相似文献

IntroductionSurgery of GCTB in sacrum and pelvis is challenging, with high rates of complications and local recurrence. Denosumab can consolidate the peripheral rim of the tumour, thus reducing the rate of morbidities of surgery. The aim of this paper is to evaluate the use of denosumab in pelvic/sacrum giant cell tumours of bone (GCTB).Patients and methodsWe retrospectively reviewed a cohort of 26 patients with aggressive GCTB in sacrum or pelvis treated with denosumab at two referral centres. Clinical response and local recurrence were recorded and the radiologic responses were evaluated with the MDA criteria.Results69% of the pelvic GCTB treated with denosumab presented partial or good radiologic responses (type 2A or 2B) after 49 weeks of treatment. Denosumab was administered as adjuvant therapy prior and after surgery in 11 patients (group A), and as the only treatment in 15 patients (group B). In group A, 62% of local recurrence was observed in patients treated with intralesional curettage. No recurrences were identified after en bloc resection. In group B, 9 patients were on continuous bimonthly long term denosumab administration with type 2A and 2B responses. Six patients stopped denosumab and 66% remained stable after 10 months of follow-up.ConclusionsLong-term denosumab therapy can be considered with curative intent for pelvic and sacrum GCTB. If surgical intervention is required wide resection may be advisable to reduce the risk of recurrence. 相似文献

Pneumonectomy vs lobectomy in the treatment of pathologic N1 NSCLC: could the type of surgical resection dictate survival? 总被引:3,自引:0,他引:3

AIM: To define the prognostic significance of specific types of N1 lymph node involvement in patients operated on for stage II (N1) NSCLC and to evaluate if the extent of resection affects survival. METHODS: Of 1117 patients operated on from 1985 to 1998, an homogeneous group of 124 consecutive patients with pathologic T1-T2 N1 disease who had undergone a complete resection with systematic nodal dissection were analysed. No patients received adjuvant radio- or chemotherapy. RESULTS: The overall 5-year survival rate was 48.8%. Survival was not related to pathologic T factor, histology, number, percentage or level of N1 involved, visceral pleura involvement, number of lymph nodes dissected. Patients were then divided into 3 groups depending on the level of lymph node involvement (stations 10, 11 and 12-13) and survival analysed according to the extent of resection (pneumonectomy vs lobectomy). No significant difference was found, however, in the group of level 10, patients treated by pneumonectomy showed a better 5-year survival (58%) compared to patients treated by lobectomy (33%) with a median survival of 110 against 58 months. This data was confirmed by a lower incidence of local recurrence in the pneumonectomy group than lobectomy group (0% vs 24%), whereas the same incidence of distant metastases was observed in the two groups (29% vs 23%). CONCLUSIONS: In patients with stage II (N1) NSCLC, only in case of station 10 involved, pneumonectomy could allow a better survival lowering the incidence of local recurrence. However the major part of patients with stage II (N1) NSCLC die for distant metastasis. This supports the necessity to develop a specific systemic treatment. 相似文献

Osteochondral plugs were harvested from eight fresh human femoral condyles within 96 hours of donor death. The plugs were either stored in a serum-free media containing glucose, salts, and amino acids or 10% fetal bovine serum at 4 degrees C. After 28 days of storage, the osteochondral plugs were analyzed for chondrocyte viability and viable cell density using confocal microscopy, proteoglycan synthesis by (35)SO4 incorporation, and glycosaminoglycan content. Chondrocyte viability and cell density were significantly lower in grafts stored in serum-free media compared to fetal bovine serum, 27% versus 68% (P < .001) and 3250 cells/mm3 versus 8960 cells/mm3, respectively (P < .001). The metabolic activity determined by proteoglycan synthesis was significantly better in the specimens stored in fetal bovine serum (P < .01). No significant difference was detected between the glycosaminoglycan content in any of the specimens. These data suggest that the quality of osteochondral allografts as measured by chondrocyte viability, viable cell density, and proteoglycan synthesis is superior after storage in fetal bovine serum versus serum-free media. These results must be taken cautiously, however, as the clinical ramifications of storage in fetal bovine serum, including potential infectious disease transmission risks and immunogenic factors, have yet to be studied. 相似文献

Since the advent of cemented hip replacements inthe 1950s, outcomes of cementing techniques in the stem have improved significantly. These improvements have not translated as readily to the acetabulum. This article suggests further techniques of improving cementiig techniques in the acetabulum. 相似文献
