Renal cell carcinoma: should radical nephrectomy be performed in the presence of metastatic disease?
Metastatic renal cell carcinoma is associated with an unfavorable prognosis and the treatment options are limited. Adjunctive radical nephrectomy, performed either before or after the administration of systemic immunotherapy, has been proposed as a means of improving outcome. The role of nephrectomy for patients with metastatic disease remains controversial. This article reviews the role of nephrectomy in metastatic renal cell carcinoma and the optimal timing for surgery relative to immunotherapy. 相似文献

This overview presents new insights into renal cell carcinoma (RCC). The search for new target structures for targeted therapy as well as diagnostic and prognostic markers continues to remain a desirable area of research. Investigations are focusing on the use of well-established and new therapeutic agents for metastatic RCC and an increasingly liberal indication for organ-sparing surgery for renal tumors. The response to systemic treatment in metastatic RCC is also being evaluated in defined subpopulations. 相似文献

OBJECTIVES: The role of simultaneous adrenalectomy in combination with radical nephrectomy in the treatment for renal cell carcinoma (RCC) remains controversial. With nephron-sparing surgery being commonly applied, the indication for adrenalectomy has to be critically assessed. PATIENTS AND METHODS: In a retrospective analysis the outcome of 589 patients, who underwent ipsilateral adrenalectomy along with radical nephrectomy in the treatment for RCC between 1985 and 1997 at our institution, was evaluated. The mean follow-up time was 34 months (range 1-95). RESULTS: Histologically an ipsilateral adrenal metastasis was found in 19/589 patients (3.2%). 16/19 patients had >/= T3, 3/19 had T1 tumours. The average size of the primary tumours with adrenal metastasis was 7.8 cm (range 2.3-13) in diameter with no preferential primary tumour site within the kidney (6/19 upper, 4/19 middle and 9/19 lower third). Only 4/19 patients had suspect adrenal findings in preoperative diagnostics (ultrasound, CT scan). 6/19 (31.5%) patients with adrenal metastasis are alive without evidence of disease at a mean of 41 months (range 11-95) after surgery for RCC. CONCLUSIONS: The probability of adrenal metastasis correlates with primary tumour stage, but not with its location within the kidney. The preoperative diagnostics are not reliable concerning small adrenal metastases. We thus still recommend simultaneous adrenalectomy in those cases where radical nephrectomy in patients with RCC is indicated. 相似文献

Laparoscopic sigmoid resection for diverticulitis: is learning phase associated with increased morbidity? 总被引:4,自引:0,他引:4
AIM: To assess retrospectively the results of laparoscopic sigmidectomy for diverticulitis, with intent to treat, in 58 consecutive patients operating by one surgeon compared with a control group operating by laparotomy. MATERIALS AND METHODS: From 1995 to 2001, 90 consecutive patients undergoing elective sigmoid resection for diverticulitis were divided into 3 groups: laparotomy (Group 1 : n = 32), first cases of laparoscopy (Group 2 : n = 29) and last cases of laparoscopy (Group 3 : n = 29). These 3 groups were similar according to age, sex, Body Mass Index (BMI), American society of anesthesia score (ASA), previous abdominal surgery, number of attacks of diverticulitis, and time between last attack and surgery. Following criteria were studied: operating time, conversation rate, intra-operative and post-operative morbidity, return of intestinal transit, and hospital stay. RESULTS: During laparoscopy, conversion was mandatory in 24% of the cases (7/29) in group 2 and 14% in group 3 (4/29; NS). No intra-operative morbidity was noted in the 58 laparoscopies. Mean operative time was 240 min in group 1, 259 min in group 2, and 241 min in group 3 (NS). Postoperative morbidity was observed in 31% of patients in group 1, 34% in group 2, and 10% in group 3 (p = 0.02). Returm of intestinal transit and oral ingestion and mean hospital stay were significantly shorter in group 2 and group 3 versus group 1 (p < 0.05). CONCLUSION: Our results confirm previous data demonstrating faisability of laparoscopic sigmodectomy for diverticulitis and its benefice in terms of return of intestinal transit and hospital stay. Furthermore, our study suggest that when surgeon gain experience, conversion rate, morbidity and operative time can be reduced. 相似文献

Background
Laparoscopic surgery for penetrating Crohn’s disease (CD) still remains highly conflicting due to a lack of sufficient data. Therefore, the following large study was designed to compare postoperative outcomes after minimal-invasive resections for penetrating and non-penetrating CD.Methods
Consecutive patients, who underwent laparoscopic intestinal resection for symptomatic CD at a tertiary academic referral center, were included. Patients were divided according to perioperative findings in penetrating and non-penetrating type of disease. All clinical data were obtained from an institutional database and analyzed retrospectively.Results
Of 234 patients enrolled, 101 patients [females: n = 54 (53.5 %)] were operated on for non-penetrating CD and 133 patients [females: n = 50 (37.6 %)] for penetrating CD. Fistulas (p < 0.001), inflammatory mass (p < 0.001) and abscess formation (p < 0.001) were observed more frequently in the perforating group. Ileocolic resections were performed predominantly in both groups [perforating CD: n = 110 (82.7 %), non-perforating CD: n = 82 (81.2 %)], with more complex resections (>1 intestinal resection) found in perforating CD (p < 0.001). Conversion rates did not differ significantly. Notably, 30-day postoperative morbidity was comparable for both groups [perforating CD: n = 20 (15 %), non-perforating CD: n = 19 (18.8 %), p = 0.44]. Postoperative complication rates graded according to the Clavien–Dindo classification showed no difference too (p = 0.49).Conclusion
Laparoscopic surgery can be conducted safely in selected patients with penetrating CD without increasing the risk of postoperative complications. This finding needs to be implemented in future guidelines.10.

ObjectivesThe incidence of metastatic disease in patients with renal cell carcinoma (RCC) correlates with tumor size. We sought to determine the incidence of metastatic disease by tumor size, and the utilization and impact of nephron-sparing surgery on survival in those with metastatic disease.Materials and methodsUtilizing the Surveillance, Epidemiology, and End Results (SEER) database, we identified 56,011 patients between 1988 and 2005 diagnosed with RCC. Patients were initially separated into two groups—those with and without metastatic disease—and stratified by tumor size. Cox proportional hazard modeling and Kaplan-Meier analyses were then utilized to evaluate the role of gender, age, grade, histology, tumor size, and type of surgery (radical vs. partial nephrectomy) on overall- and cancer-specific survival in patients with metastatic disease.ResultsEight thousand four hundred ninety-eight patients (15%) had metastatic disease. Four percent of patients with tumors less than 2 cm and 5% of patients with tumors between 2 and 3 cm presented with metastatic disease. Two thousand nine hundred fifty patients (35%) with metastatic disease underwent surgery (radical or partial nephrectomy). Seventy patients (2% of those undergoing surgery) had a partial nephrectomy. Those who underwent partial nephrectomy were 0.49 times less likely to die of RCC than those who underwent radical nephrectomy (95% CI 0.35–0.69, P < 0.001).ConclusionsAlbeit small, the risk of metastases in patients with small kidney tumors is distinct and should be considered in management discussions. Partial nephrectomy, when able to be done, should be utilized in the setting of metastatic disease. 相似文献

OBJECTIVE
To evaluate the prognostic impact of capsular involvement (CaI) in patients treated exclusively with partial nephrectomy (PN) for localized renal cell carcinoma (RCC), as in these patients CaI was recently reported as an adverse prognostic factor.PATIENTS AND METHODS
We retrospectively reviewed the medical records of patients treated with PN for a sporadic and localized RCC (pT1‐pT2N0M0) in our institution between 1985 and 2005. Univariate and multivariate analysis using a Cox proportional‐hazards regression analysis were conducted to identify significant predictors of oncological outcome for several clinical and pathological factors, i.e. imperative indication, histological type, Fuhrman grade, tumour size, T stage, CaI, and surgical margins. Disease‐free and ‐specific survival rates of patients with CaI and no evidence of CaI were compared using the log‐rank test.RESULTS
In all, 305 patients had a PN for localized RCC, of whom 22 (7.2%) had CaI in the PN specimen. The median (range) follow‐up was 6 (1.5–23) years. Multivariate statistical analysis showed that imperative indication for PN and high‐grade RCC were independently associated with worse disease‐free and ‐specific survival, whereas CaI had no prognostic value. Disease‐free and ‐specific survival in patients with and without CaI were not significantly different at 5 and 10 years.CONCLUSIONS
In a contemporary series of patients exclusively treated with PN for localized RCC, CaI was not predictive of disease recurrence and disease‐specific mortality. These results do not support the use of any change in postoperative management in patients with CaI after PN. 相似文献13.
Laparoscopic radical nephrectomy for renal cell carcinoma: the standard of care already? 总被引:4,自引:0,他引:4

PURPOSE OF REVIEW: Laparoscopic radical nephrectomy has been developed and applied for patients with renal cell carcinoma since 1992. The number of patients undergoing laparoscopic radical nephrectomy has increased explosively worldwide in recent years, and laparoscopy is now extended to patients with advanced disease. It is very important to clarify the present status of laparoscopic radical nephrectomy among the treatment modalities for patients with renal cell carcinoma. RECENT FINDINGS: Laparoscopic radical nephrectomy has a minimally invasive nature as well as comparable long-term cancer control in patients with pT1-3a renal cell carcinoma to open surgery. It is technically applicable for N1-2 disease and T3b disease if the tumor thrombus is within the renal vein. Also, it is feasible as a cytoreductive surgery for patients with M1 disease. SUMMARY: Laparoscopic radical nephrectomy is a standard treatment modality for T1-3a renal cell carcinoma patients. It is also available for treating patients with N1-2 disease, and for patients with M1 disease as a cytoreductive surgery. 相似文献

Objective
To find a cutoff of hospital volume for elective partial nephrectomy (PN) for kidney cancer that can minimize the inpatient morbidity of this procedure.Material and methods
Analyzing the National Inpatient sample, from 2008 to 2011, we selected 8,753 records of adult patients undergoing elective PN for nonmetastatic kidney cancer, representing an estimated 43,178 partial nephrectomies performed in the United States during this period. Of these, 2,187 (estimated 10,848) PNs were performed via the robotic approach. International Classification of Diseases, Ninth Revision, diagnosis and procedure codes were used to define complications. Logistic regression within generalized estimating equation framework, with restricted cubic splines was used to identify the relationship of any inpatient complications and major inpatient complications with annual hospital PN volume, after adjusting for demographic characteristics, insurance status, location, and comorbidities. A similar analysis was done for a subset of patients undergoing robot-assisted PN.Results
Overall, rate of any inpatient complication and major inpatient complications was 1,801/8,753 (20.6%) and 839/8,753 (9.6%), respectively. Median annual hospital volume was 27 cases (interquartile range: 11–64). Restricted cubic spline analysis revealed a significant inverse nonlinear association between annual hospital volume and any inpatient complications (P<0.001). The odds of complications decreased with increasing annual hospital volume, with plateauing seen at 35 to 40 cases for both any inpatient complications and major inpatient complications. Analysis on a subset of robot-assisted PN revealed a similar inverse nonlinear relationship, with plateauing at 18 to 20 cases annually.Conclusion
There is an inverse nonlinear relationship of hospital volume with morbidity of PN, with a plateauing seen at 35 to 40 cases annually overall, and at 18 to 20 cases for robot-assisted PN. 相似文献15.

Conservative renal surgery for cancer has now achieved consensus for imperative, relative, and elective indications (tumor < 4 cm with healthy contralateral kidney). The results show 90%-100% 10-year survival rates and 0%-3% recurrence rates. Surgical techniques are improving and complication rates are decreasing with experience. It is now recognized that margin thickness has no real significance provided that it is negative, even if excision is flush with the tumor capsule. Finally, the frequently cited multifocal lesions are no longer an argument against conservative surgery. The usual limitations of conservative surgery are the size and location of the tumor. Nevertheless, there is no statistically significant difference in the survival and recurrence rates between T1a (< 4 cm) and T1b (4-7 cm) tumors, even if the risk of renal sinus fat tissue involvement increases proportionally with tumor size. Finally, resecting tumors of the renal sinus is possible without adding to the risk of metastasis but increases the risk of surgical complications. The risk of deteriorated renal function with radical nephrectomy is now well documented. Laparoscopy, which has become the reference treatment mode for radical nephrectomy, remains reserved for conservative surgery for exophytic tumors less than 3-4 cm because of the technical difficulties involved in resection and hemostasis. Although conservative surgery is now recognized, extending its indications to tumors greater than 4 cm or in cases of parenchymatous location is supported by real arguments that need to be confirmed. The limit remains the surgical feasibility. 相似文献

IntroductionLong bone fractures are assumed to be an independent risk factor for systemic complications and death after trauma. Multiple studies have identified an increased risk for mortality and morbidity in patients with bilateral femoral fractures. Data about bilateral tibial shaft fractures is rare. The aim of our study was to analyze if patients with bilateral tibial shaft fractures are at higher risk for systemic complications.MethodsWe performed a retrospective analysis of the TraumaRegister DGU® from 1993 to 2008. Inclusion criteria were unilateral or bilateral tibial shaft fractures and an age ≥16. Additionally to the overall collective we analyzed different subgroups (divided into different injury severities and treatment periods).Results1899 patients with unilateral and 175 patients with bilateral tibial shaft fractures were included. Age, gender and mean ISS (25.8 vs. 26.2, p = 0.51) in the two groups were comparable. Regarding the entire study population, patients with bilateral tibial shaft fractures showed no significant higher incidence of respiratory organ failure (29.5% vs. 23.1%, p = 0.076) or mortality (20.0% vs. 16.3%, p = 0.203). However, subgroup analysis showed a significant higher rate of pulmonary organ failure for bilateral tibial shaft fractures as compared to unilateral tibial shaft fractures in the group ISS < 25 (20.7% vs. 11.7%, p = 0.023). Multivariate regression analysis identified the additional tibial shaft fracture as an independent risk factor for pulmonary organ failure (OR = 1.56) but not for mortality.DiscussionThe additional tibial shaft fracture is an independent risk factor for pulmonary organ failure but not for multiple organ failure or mortality. The impact of the additional tibial shaft fracture is especially pronounced in less severely injured patients (ISS < 25). These findings are comparable to results of bilateral femoral fracture studies and we therefore suggest to treat patients with bilateral tibial shaft fractures with the same caution as those with bilateral femoral fractures. 相似文献

BACKGROUND: Thyroid carcinoma occurring as a second primary associated with head and neck squamous cell carcinoma (HNSCC) is unusual. The clinical management of thyroid cancer in such cases has been debated. METHODS: Between 1975 and 2004, we collected 33 cases. The associated thyroid carcinoma was diagnosed either during or as a consequence of surgery planned as head and neck cancer treatment. RESULTS: The associated thyroid carcinoma was never seen to recur. Five-year overall survival was 41%. Disease-free survival after 40 and 66 months was 11.1% and 5.6%, respectively. CONCLUSIONS: We consider the treatment of thyroid cancer to be complete when the thyroid gland, either with or without lymph nodes, has been included in the specimen obtained during surgery for HNSCC. In the group of cases in which associated thyroid carcinoma was only found within the neck lymph nodes and the thyroid gland has not been treated, we discourage further surgical treatment or radioactive iodine therapy. 相似文献

Renal paratransplant hernia constitutes an unusual variant of internal hernia caused by entrapment of bowel through a defect in the peritoneum covering the transplanted kidney. Only three cases have been previously reported. We present three new cases of renal paratransplant hernia. Abdominal pain and vomiting were the main symptoms. Clinical diagnosis of bowel obstruction and paratransplant hernia was reached using abdominal CT scan. All patients underwent an emergency surgical procedure, and one patient needed resection of necrotic bowel. The three patients survived owing to early surgical intervention, and they were discharged asymptomatic. Paratransplant hernia represented 1.1% of our series of transplant patients. Early diagnosis and surgical treatment are esential in transplant patients with bowel obstruction to avoid high morbidity and mortality rates. 相似文献
