PurposeTo investigate the value of 18 FDG PET/CT volumetric parameters in the prediction of overall survival (OS) in patients with pancreatic cancer and also, assess their independence relative to well-established clinico-pathological variables.MethodsWe conducted a retrospective analysis of patients with a confirmed diagnosis of pancreatic cancer who underwent 18 FDG PET/CT. The tumour maximum standardised uptake value (SUVmax) in addition to SUVmean, metabolic tumour volume (MTV) and total lesion glycolysis (TLG) were calculated. The prognostic value of 18 FDG PET/CT and clinico-pathological parameters for OS were assessed using univariate and multivariable analyses.ResultsA sum of 89 patients were analysed in this study. Median survival for patients categorised as having high TLG (≥55) and low TLG (<55) was 18 vs 5 months (p < 0.001). Similarly, the respective high vs low SUVmean, MTV and SUVmax were 18 vs 6 months (p = 0.001), 16 vs 6 months (p = 0.002) and 18 vs 6 months (p = 0.001). Univariate analysis showed SUVmax, SUVmean, MTV, TLG, tumour size, tumour differentiation and presence of distant metastasis as prognostic factors for OS. On multivariable analysis, TLG (HR 2.0, 95% CI 1.26–3.18, p = 0.004) and the presence of distant metastasis (HR 3.37, 95% CI 1.97–5.77, p < 0.001) emerged as independent prognostic factors. Subgroup analysis identified TLG as the only significant PET metric after adjusting for the presence of distant metastasis.Conclusions18 FDG PET/CT is a useful tool in the preoperative evaluation of patients with pancreatic cancer. Tumour TLG offer an independent prognostic value in both potentially operable and metastatic disease settings. 相似文献

ObjectiveOver the past decade numbers of bilateral mastectomy have increased steadily. As a result, bilateral breast reconstruction is gaining popularity. The presented study compares complications and outcomes of unilateral and bilateral DIEP free-flap breast reconstructions using the largest database available in Europe.MethodsFemale breast cancer patients (n = 3926) receiving DIEP flap breast reconstructions (n = 4577 free flaps) at 22 different centers were included in this study. Free flaps were stratified into two groups: a unilateral- (UL) and a bilateral- (BL) breast reconstruction group. Groups were compared with regard to surgical complications and free flap outcome.ResultsMean operative time was significantly longer in the BL group (UL: 285.2 ± 107.7 vs. BL: 399.1 ± 136.8 min; p < 0.001). Mean ischemia time was comparable between groups (p = 0.741). There was no significant difference with regard to total (UL 1.8% vs. BL 2.6%, p = 0.081) or partial flap loss (UL 1.2% vs. BL 0.9%, p = 0.45) between both groups. Rates of venous or arterial thrombosis were comparable between both groups (venous: UL 2.9% vs. BL 2.2%, p = 0.189; arterial: UL 1.8% vs. BL 1.2%, p = 0.182). However, significantly higher rates of hematoma at the donor and recipient site were observed in the UL group (donor site: UL 1.1% vs. BL 0.1%, p = 0.001; recipient site UL 3.9% vs. BL 1.7%, p < 0.001).ConclusionsThe data underline the feasibility of bilateral DIEP flap reconstruction, when performed in a setting of specialized centers. 相似文献

BackgroundThe surgical management of retroperitoneal sarcomas frequently involves complex multivisceral resections, however retroperitoneal liposarcoma (LPS) rarely invade major abdominal vessels. The aim of the study was to assess association of major vascular resections with outcome of primary LPS.MethodsAll consecutive patients who underwent resection at our institutions for primary LPS between 2002 and 2019 were included. A propensity matched analysis was performed, adjusting the groups for the variables of Sarculator, to assess the effect of vascular resection on oncological outcomes.ResultsOverall 425 patients were identified. Twenty-four (5%) patients had vascular resection. At final pathology 18 patients had vascular infiltration, 2 vascular encasement and 4 involvement without infiltration. Vascular resection was associated with longer operative time (480′ vs. 330’; p < 0.001) and greater need for transfusions (4 vs. 0 units; p < 0.001), and was burdened by a higher rate of major complications (54% vs. 25%; p = 0.002). After propensity matched analysis, patients undergoing vascular resection had a lower 5-year OS (60% vs. 81%; p = 0.05), and a higher incidence of local and distant recurrence at 5 years (local: 45% vs. 24%, p = 0.05; distant: 20% vs. 0%, p = 0.04).ConclusionsVascular resection is feasible and safe even in the context of multivisceral resection for primary retroperitoneal liposarcomas, although associated to a higher complication rate. However, the independent association between vascular involvement and a higher risk of local recurrence, distant metastases and death may imply a more aggressive biology, which should be factored in the initial management of this complex disease. 相似文献

BackgroundT4 tumours comprise a heterogeneous group of locally invasive non-small cell lung cancers (NSCLC). Intrapericardial and extrapericardial involvement of the pulmonary artery (PA) may have a different prognosis. We compared the short and long-term surgery outcomes for NSCLC of the PA with intrapericardial or extrapericardial involvement.MethodsThis is a multicenter retrospective study that included 129 patients who received an anatomical resection with PA resection and reconstruction in our centres between January 2000 and December 2018. Extrapericardial group included 70 patients, while the intrapericardial included 59.ResultsDifferences in outcomes were found in terms of left side surgery (more common in extrapericardial, p = 0.010), type of lung resection (p < 0.001), Clavien-Dindo score (p = 0.012) and 90-day mortality (1.4 vs 16.9%, p = 0.002). Overall survival (OS, 91.11 ± 63.78 vs 63.78 ± 58.241 months, p = 0.008) and tumour-free survival (TFS, 68.17 ± 71.57 vs 45.44 ± 61.32 months, p = 0.007) were statistically different. OS stratification for performed pneumonectomy, pathological lymph node status and pattern of recurrence were statistically different (p = 0.017, 0.040, <0.001). Differences were found in terms of recurrence months stratified for recurrence pattern (p < 0.001).ConclusionsAccording to our results, the difference between PA involvement is significant in terms of survival and complications. A T4 subset or a shift to T3 for extrapericardial involvement of the PA may lead to a change in staging and surgical approach for these patients. 相似文献

BackgroundAdvanced age is associated with worse outcomes after open rectal cancer surgery. However, not much is known about outcomes of minimally invasive surgery (MIS) in the elderly. The aim of this study was to evaluate safety and efficacy of MIS in elderly rectal cancer patients using the Bi-national Colorectal Cancer Audit (BCCA) data from Australia and New Zealand (ANZ).Methods3451 patients were included, divided into three groups: <50 years (n = 364), 50–74 years (n = 2157) and ≥75 years (n = 930). Propensity-score matching was performed for the elderly group analysis to correct for differences in baseline characteristics.ResultsMIS was performed in 52.9% of elderly patients, slightly lower than rates in <50 year and 50–74 year old groups (61% and 55.5%, respectively, p = 0.022). Elderly patients had more postoperative complications (p < 0.0001) and had a longer length of hospital stay (LOS; median 11 vs. 8 days for both other groups; p < 0.0001). Elderly patients had higher (y)pT-stages compared to both other groups (p < 0.0001) and were less likely to receive adjuvant therapy (p < 0.0001). Propensity-score matched analysis of the elderly group showed a higher rate of superficial wound dehiscence and a longer LOS after open surgery compared to MIS (10.3% vs. 2.6%, p = 0.030; 12 days vs. 9.5 days, p = 0.001, respectively), with comparable short-term oncological outcomes.ConclusionsMIS is performed in just over half of elderly rectal cancer patients who are selected for elective rectal resection surgery in ANZ. When performed in the elderly, MIS appears safe and is associated with fewer wound complications and a shorter LOS. 相似文献

Background and aimsWe aimed to investigate the impact of the site of the primary on postoperative and oncological outcomes in patients undergone simultaneous approach for colon (CC) and rectal cancer (RC) with synchronous liver metastases (SCRLM).Patients and methodsOf the 220 patients with SCRLM operated on between Mar 2006 and Dec 2017, 169 patients (76.8%) were treated by a simultaneous approach and were included in the study. Two groups were considered according to the location of primary tumor RC-Group (n = 47) and CC-group (n = 122).ResultsMultiple liver metastases were observed in 70.2% in RC-Group and 77.0% in CC-Group (p = 0.233), whilst median Tumor Burden Score (TBS) was 4.7 in RC-Group and 5.4 CC-Group (p = 0.276). Severe morbidity (p = 0.315) and mortality at 90 days (p = 0.520) were comparable between RC-Group and CC-Group. The 5-year overall survival (OS) rate was similar comparing RC-Group and CC-Group (48.2% vs. 45.3%; p = 0.709), but it was significantly different when considering left-CC, right-CC and RC separately (54.5% vs. 35.2% vs. 48.2%; p = 0.041). Primary tumor location (right-CC, p = 0.001; RC, p = 0.002), microscopic residual (R1) disease at the primary (p < 0.001), TBS ≥6 (p = 0.012), bilobar metastases (p = 0.004), and chemotherapy strategy (preoperative ChT, p = 0.253; postoperative ChT, p = 0.012; and perioperative ChT, p < 0.001) resulted to be independent prognostic factors at multivariable analysis.ConclusionIn patients with SCRLM, simultaneous resection of the primary tumor and liver metastases seems feasible and safe and allows satisfactory oncological outcomes both in CC and RC. Right-CC shows a worse prognosis when compared to left-CC and RC. 相似文献

IntroductionMulticenter retrospective analysis of robotic partial nephrectomy for completely endophytic renal tumors (i.e. 3 points for the ‘E’ domain of the R.E.N.A.L. nephrometry score) was performed.Materials and methodsPatients’ demographics, tumor characteristics, perioperative, functional, pathological and oncological data were analyzed and compared with those of patients with exophytic and mesophytic masses (i.e. 1 and 2 points for the ‘E’ domain, respectively). Multivariable logistic regression analysis was used to assess variables for trifecta achievement (negative margin, no postoperative complications, and 90% estimated glomerular filtration rate [eGFR] recovery).ResultsOverall, 147 patients were included in the study group. Patients with a completely endophytic mass had bigger tumors (mean 4.2 vs. 4.1 vs. 3.2 cm; p < 0.001) on preoperative imaging and higher overall R.E.N.A.L. score. There was no difference in mean operative time. Estimated blood loss was higher in the endophytic group (mean 177.75 vs. 185.5 vs. 130 ml; p = 0.001). Warm ischemia time was shorter for the exophytic group (median 16 vs. 21 vs. 22 min; p < 0.001). Postoperative complications were more frequent in patients with endophytic tumor (24.8% vs. 19.5% vs. 14.8%; p < 0.001). Six (4.5%) patients had positive surgical margins, there was no difference between groups. Trifecta was achieved in 44 patients in endophytic group (45.4 vs. 68.8 and 50.9%, p < 0.001). Multivariable analysis for trifecta revealed that clinical tumor size (odds ratio: 0.667, 95% confidence interval: 0.56–0.79, p < 0.001) was only significant predictor for trifecta achievement.ConclusionsOur findings confirm that RAPN in case of completely endophytic renal masses can be performed with acceptable outcomes in centers with significant robotic expertise. 相似文献

BackgroundDue to the risk of postoperative hypotension (PH), invasive monitoring is recommended for patients who undergo adrenalectomy for phaeochromocytoma. Due to high costs and limited availability of intensive care, our aim was to identify patients at low risk of PH who may not require invasive monitoring.MethodsData for patients who underwent adrenalectomy for phaeochromocytoma between 2012 and 2020 were retrospectively collected by nine UK centres, including patient demographics, intraoperative and postoperative haemodynamic parameters. Independent risk factors for PH were analysed and used to develop a clinical risk score.ResultsPH developed in 118 of 430 (27.4%) patients. On univariable analysis, female sex (p = 0.007), tumour size (p < 0.001), preoperative catecholamine level (p < 0.001), open surgery (p < 0.001) and epidural analgesia (p = 0.006) were identified as risk factors for PH. On multivariable analysis, female sex (OR 1.85, CI95%, 1.09–3.13, p = 0.02), preoperative catecholamine level (OR: 3.11, CI95%, 1.74–5.55, p < 0.001), open surgery (OR: 3.31, CI95%, 1.57–6.97, p = 0.002) and preoperative mean arterial blood pressure (OR: 0.59, CI95%, 0.48–1.02, p = 0.08) were independently associated with PH, and were incorporated into a clinical risk score (AUROC 0.69, C-statistic 0.69). The risk of PH was 25% and 68% in low and high risk patients, respectively.ConclusionThe derived risk score allows stratification of patients at risk of postoperative hypotension after adrenalectomy for phaeochromocytoma. Postoperatively, low risk patients may be managed on a surgical ward, whilst high risk patients should undergo invasive monitoring. 相似文献

BackgroundThe surgical treatment of advanced non-small-cell-lung-cancer (NSCLC) invading mediastinal organs and great vessels is still controversial. The aim of this multicentre study is to analyse oncological outcomes, surgical outcomes and prognostic factors of patients with NSCLC involving heart and great vessels.Methods362 patients treated surgically for locally advanced T4-NCSLC between 1990 and 2020 were retrospectively reviewed. Patients were divided into five subgroups: pulmonary artery(n = 129), left atrium(n = 82), superior vena cava(n = 80), aorta(n = 43), and multiple vascular structures(n = 28). Resection was complete in 327(90%) patients.ResultsOverall 90-day mortality was 8.8%, influenced by poly-transfusions, pneumonectomy, bronchopleural fistula and previous cardiovascular disease (4.5HR.p = 0.03, 3.7HR p = 0.01, 14.0HR.p < 0.001 and 3.0HR p < 0.01). One-, 3- and 5-year survival rates were 75%, 43%, 33%, respectively and there were significant differences among the five groups(p < 0.001). Survival was significantly affected by induction radiotherapy, nodal status, pTNM-stage and radicality (3.8HR p = 0.03, 2.6HR p = 0.001, 1.6HR p < 0.05 and 1.6HR p < 0.05).ConclusionsSurgery provided acceptable results in selected patients with T4-NSCLC with major vascular infiltration in expert centres. Nodal-status and radicality influenced the overall-survival and disease-free survival. Neoadjuvant chemotherapy appears to have a positive effect on long-term results, particularly in N2-patients. 相似文献

ObjectiveTo analyze histological factors possibly associated with lymphovascular space invasion (LVSI) and to determine which of those can act as independent surrogate markers.MethodsRetrospective cohort study performed between January 2001 and December 2014. LVSI was defined as the presence of tumor cells inside a space completely surrounded by endothelial cells. Risk factors evaluated included myometrial invasion, tumor grade, size, location, and cervical invasion. Univariate logistical regression models were applied to study any possible association of LVSI with these factors. Values were adjusted by multivariate logistic regression analysis.ResultsA total of 327 patients with endometrial carcinoma treated in our Centre were included. LVSI was observed in 120 patients (36.7%). Lower uterine segment involvement (OR 5.21, 95% CI:2.6–10.4, p < 0.001) and size ≥2 cm (OR 2.62, 95% CI: 1.14–6.1, p < 0.001) were independent factors for LSVI in multivariate analysis. In univariate analysis, LVSI was a surrogate marker in type 1 tumors with deep myometrial invasion (IB, 51.9% vs. IA, 16.0%; p < 0.001), grade 3 (G3 55.8% vs. G1 16.2%; p < 0.001), size ≥2 cm (37.9% vs. 16.1%, p = 0.005), those with involving the lower segment of the uterus (58.9% vs. 22.5%, p < 0.001) and/or with cervical stromal invasion (65.4% vs. 26.1%, p < 0.001), and in type 2 tumors (61.5% vs. 30.5%, p < 0.001). The use of uterine manipulator did not increase the rate of LVSI (35.5% vs. 40.5%, p = 0.612) as compared to no manipulator use.ConclusionsSize ≥2 cm and involvement of the lower uterine segment are independent factors for LSVI, in type 1 tumors, which can be used for surgical planning. LVSI is also more common in type 1 tumors with deep myometrial invasion, grade 3 and/or cervical stromal invasion, and also in type 2 tumors. The use of a uterine manipulator does not increase LVSI. 相似文献

PurposeRadical nephroureterectomy is the gold standard of treatment for high-risk non-metastatic urothelial carcinoma of the upper urinary tract. However, the optimal surgical approach remains a controversial debate. This study compared the perioperative and oncological outcomes of open and robot-assisted radical nephroureterectomies.Methods131 consecutive radical nephroureterectomies (66 robot-assisted nephroureterectomies vs. 65 open nephroureterectomies) for urothelial carcinoma of the upper urinary tract at a single tertiary referral center were included from 2009 to 2019. The perioperative and oncological outcomes were compared between both surgical approaches, including logistic regression analysis, propensity score matching, Kaplan Meier analyses, and Cox regression models.ResultsOverall, robot-assisted surgery had less blood loss (150 ml vs. 250, p = 0.004) and less positive surgical margins (1.5% vs. 15.4%, p = 0.004) at a comparable operating time (robotic 188min vs. 178). Any grade complications were more frequent after open surgery (40.9% vs. 63.1%, p = 0.011), and the length of stay was shorter after robotic nephroureterectomy (9 days vs. 12, p < 0.001). These differences remained significant in the propensity score matched analysis, except for the complication rates, which were still lower for the robotic approach, but no longer significant. At a median follow-up of 30.9 months (range 1.4–129.5), neither the progression-free survival (PFS, 2-year: robotic 66.7% vs. open 55.3%), nor the overall survival differed significantly (OS, 2-year: robotic 76.2% vs. open 68.4%). In the Cox regression, the surgical approach did not impact the PFS or OS. Lymph node metastases (HR 3.32, p = 0.008) had the strongest impact on the PFS besides patient age (HR 1.51 per 10 years, p = 0.025) and prior cystectomy (HR 2.42, p = 0.026) in the multivariate analysis.ConclusionsRobot-assisted radical nephroureterectomy had significant perioperative advantages at comparable oncological outcomes compared to open surgery for the treatment of urothelial carcinoma of the upper urinary tract at a high volume center, experienced in robotic surgery. 相似文献

BackgroundSurgical resection is recommended for patients with resectable acinar cell carcinoma (ACC). The aim of this study was to investigate the clinical characteristics and surgical outcomes of resectable ACC in comparison to pancreatic ductal adenocarcinoma (PDAC).MethodA retrospective analysis was performed on all patients who consecutively underwent radical resection with pathologically confirmed ACC and PDAC from December 2011 to December 2018. Clinicopathologic characteristics and follow-up information were analyzed. A 1:3 propensity score matching (PSM) method was used to minimize the bias between ACC and PDAC.ResultsA total of 26 patients with ACC and 1351 with PDAC were included. Compared to PDAC, ACC tended to be larger (4.5 vs. 3.0 cm; p < 0.001) and more frequently located in the pancreatic body/tail (61.5% vs. 36.6%, p = 0.009), with lower total bilirubin levels, lower neutrophil lymphocyte ratio (NLR) levels and lower carbohydrate antigen 19-9 (CA19-9) levels and carcinoembryonic antigen (CEA) levels. There was no difference in postoperative morbidities in patients with ACC and PDAC. The median OS and RFS were longer in ACC when compared to PDAC (OS: 43.5 mo vs. 19.0 mo, p = 0.004; RFS: 24.5 mo vs. 11.6 mo, p = 0.023). After the 1:3 PSM, ACC remained to be a better histological type for OS (p = 0.024), but had comparable RFS with PDAC (p = 0.164).ConclusionPatients with ACC after radical resection had better OS than that with PDAC. However, ACC is also an aggressive tumor with a similar trend of RFS with PDAC after the matching, necessitating the multidisciplinary treatment for resectable ACC disease. 相似文献

ObjectivesSarcopenia and metabolic syndrome (MetS) are associated with the prognosis from malignant tumors. However, evidence of the relationship between sarcopenia and MetS among gastric cancer (GC) patients following radical gastrectomy is lacking. This study assessed the association between preoperative sarcopenia and MetS among GC patients and analyzed the prognosis of patients with different malnutrition statuses.MethodsWe prospectively assessed the preoperative statuses of sarcopenia and MetS among patients who underwent radical gastrectomy from July 2014 to December 2017. We combined sarcopenia and MetS to generate four groups: MetS-related sarcopenia group (MSS), sarcopenia group (S), MetS group (MS), and normal group (N).ResultsA total of 749 patients with resectable GC were included in this study. Preoperative MetS was associated with sarcopenia (p < 0.001). Multivariate logistic regression presented that MetS-related sarcopenia (OR = 2.445; p = 0.010) and sarcopenia alone (OR = 2.117; p = 0.001) were independent predictors of grade Ⅱ and above complications, while MetS alone was not (p = 0.342). Cox regression analysis revealed that MetS-related sarcopenia led to the worst prognosis in the four groups (MSS vs MS: HR = 3.555, p < 0.001; MSS vs N: HR = 2.020, p = 0.003; MSS vs S: HR = 1.763, p = 0.021). However, the MetS group had better prognosis than the normal group (MS vs N: HR = 0.568, p = 0.048).ConclusionPreoperative MetS was associated with sarcopenia among GC patients. MetS-related sarcopenia resulted in a significantly worse prognosis. The long-term prognoses of patients with sarcopenia were impaired by preoperative MetS, while patients without sarcopenia benefited. Thus, patients with both sarcopenia and MetS require more medical interventions. 相似文献

BackgroundThoracoscopic lobectomy (VATS-L) for non-small-cell lung cancer (NSCLC) is a well-established option for early stage NSCLC, but the evidences are limited for octogenarians.ObjectiveThe objectives of this multi-institutional study were to evaluate the post-operative outcomes of VATS-L in octogenarians and to estimate the post-operative quality of life (QoL) using a validated questionnaire (EuroQoL5D).MethodsData from patients underwent VATS-L between 2014 and 2019 were analysed and divided into two groups: Group A (younger patients) and Group B (octogenarians). To define predictors for complications, univariate and multivariable logistic regression analysis were performed.Results7023 patients underwent VATS-L and 329 (4.6%) were octogenarians. 30-day and 90-day post-operative mortality were similar (0.95% vs 0.91%, p = 0.84 and 1.3% vs 1.2%, p = 0.58), whereas the percentage of patients who suffered from any complication (25.5% vs 31.9%, p = 0.012) and the complication rate (31.6% vs 45.2%, p=<0.01) were higher for octogenarians. At discharge, the values of EuroQoL5D were worse in group B, but after one month these levels became similar. Age >80 years had a significant influence on morbidity on both univariate and multivariable analyses (p = 0.025).ConclusionsVATS-L for NSCLC can be performed in selected octogenarians without increased risk of post-operative death, acceptable not-life-threatening complications and a moderate impact on QoL. 相似文献

IntroductionIn advanced epithelial ovarian cancer (EOC), longer time-interval from surgery to initiation of adjuvant chemotherapy (TITC) is associated with decreased survival. Adding upper abdominal surgical procedures (UAP) increases rates of both complete gross resection and postoperative complications in EOC. Our objective was to investigate the association of UAP and TITC. Moreover, if specific postoperative monitoring after the most prevalent UAP increases early detection and management of complications.Material and methodsWomen diagnosed with EOC 2014–2016 in the Stockholm/Gotland Region in Sweden were identified in the Swedish Quality Registry for Gynaecologic Cancer. The association between UAP and TITC was investigated by multivariable linear regression and adjusted for predefined confounders. The follow-up and detection of postoperative complications after diaphragm resection, splenectomy and cholecystectomy was examined.Results240 women were selected for analysis. The TITC in women subjected to UAP was similar with a median of 30 days (p = 0.99). Moreover, despite a higher rate of postoperative and major complications (p < 0.001) and longer hospital stay (p < 0.001), in the adjusted analysis there was no association between UAP and prolonged TITC, with a mean difference of −2.27 days (95% Confidence Interval (CI), −5.99 to −1.45, p = 0.23). After the most prevalent UAP (diaphragm resection, splenectomy and cholecystectomy), eventual postoperative interventions were based on routine clinical management rather than procedure-specific postoperative surveillance.ConclusionUAP does not prolong TITC despite an increased rate of postoperative complications and longer length of hospital stay. Clinical non-specific surveillance is sufficient to detect postoperative complications after the most prevalent UAP. 相似文献

BackgroundSeveral studies showed that women with low-risk endometrial cancers staged by minimally invasive surgery (MIS) experience fewer postoperative complications compared to those staged by laparotomy with similar disease-free survival (DFS) and overall survival (OS). However, high-risk patients were poorly represented. In this study, we compared DFS and OS in high-risk endometrial cancer patients who underwent surgical staging via MIS versus laparotomy.MethodsUsing a multicentric database, we compared DFS and OS between 114 patients with high-risk histology who underwent surgical staging via MIS and 114 patients who underwent laparotomy. Patients were matched for age, tumour type, FIGO stage and management criteria.ResultsAmong the 114 patients who underwent MIS, 93 underwent laparoscopy and 21 robotic surgery. Groups were comparable for stage, body mass index, histology and adjuvant therapies. However, patients in the MIS group underwent paraaortic lymphadenectomy less frequently (13% versus 29%; p = 0.01), had less lymph nodes removed (19.0 versus 28.6; p < 0.01) and had lower mean tumour size (30 versus 40 mm; p < 0.01). With a median follow-up time of 49 months, DFS and OS were not significantly different between the surgical cohorts. In multivariable analysis, both higher stage (hazard ratio [HR] = 2.2) and histology (HR = 4.9) were associated with DFS in contrast to surgical procedure (HR = 0.9).ConclusionsBeyond the benefit of MIS on immediate surgical outcome, our results show that fear for a poor long-term outcome should not be the reason to refrain from MIS in patients with high-risk endometrial cancer. 相似文献

IntroductionSentinel lymph node (SLN) biopsy algorithm has been routinely applied in all endometrial endometrioid tumors, however, no studies analyzed the feasibility of SLN mapping in endometrioid variants (EV), which included villoglandular, secretory, ciliated cell, mucinous, and squamous differentiation. This study aimed to demonstrate the feasibility of SLN biopsy in EV of EC.Materials and methodsAll patients undergoing minimally invasive surgical treatment for early-stage EC were included in the study. Patients were divided into 2 study groups: Group 1 which included patients with EV, and Group 2 which included patients with typical endometrioid histology. A propensity match analysis was performed according to age (≥65 years vs. no), BMI (≥30 kg/m2 vs. no), and LVSI (present vs. absent).ResultsAfter a 1:5 propensity-matched analysis, a total of 458 patients were identified (Group 1 n = 77, Group 2 n = 381). Overall detection rate was not statistically significant between the EV and the typical endometrioid group (94.8% vs. 92.4%, p = 0.319). Furthermore, neither bilateral nor unilateral detection rate was different between the two groups (70.1% vs. 74.8%, p = 0.267, and 23.4% vs. 17.8%, p = 0.120). BMI ≥30 kg/m2 was the only factor influencing SLN failure (p = 0.013). SLN technique showed excellent sensitivity in both the EV (100% sensitivity, p < 0.001) and the typical endometrioid unit (93.8% sensitivity, p < 0.001).ConclusionSLN research/detection for EV of endometrial cancer is a feasible and highly sensitive technique. Obesity was confirmed to be a risk factor for SLN failure. 相似文献

IntroductionSurgical resection improves survival in pancreatic ductal adenocarcinoma (PDAC) and adjuvant chemotherapy adds an additional survival-benefit. While surgical technique has improved in recent years, it remains unclear whether these improvements translate into a survival benefit independent of adjuvant chemotherapy. Thus, we aimed to clarify whether survival of patients who were treated with either Gemcitabine (GEM) or who were observed only in randomized controlled trials on adjuvant chemotherapy of PDAC improved over time.MethodsA systematic search of MEDLINE/PubMed was performed to identify randomized controlled trials on adjuvant chemotherapy of PDAC. The search was limited to studies with arms on GEM monotherapy or postoperative observation and studies were grouped by the median year of enrolment and the use of GEM. Subsequently, a meta-regression on the effect of the median year of enrolment on patient survival was performed.ResultsA total of 13 studies with 2469 patients was included, with median years of enrollment ranging from 1996 to 2015. While disease-free survival decreased in patients with postoperative observation (18.0 vs. 5.0 months, p = 0.001), median survival improved over time in patients with postoperative observation (15.8 vs. 18.4 months, p = 0.01) and in patients treated with adjuvant GEM (22.8 vs. 35.0 months, p < 0.001). One- (p ≤ 0.01) and two-year survival (p = 0.056) improved in both patients treated with adjuvant GEM and those observed only.ConclusionSurvival after surgical resection of PDAC has improved since 1996, even in patients who did not receive adjuvant chemotherapy. Improved surgical technique and postoperative management are likely to be causative factors. 相似文献

IntroductionOncological outcome might be influenced by the type of resection in total mesorectal excision (TME) for rectal cancer. The aim was to see if non-restorative LAR would have worse oncological outcome. A comparison was made between non-restorative low anterior resection (NRLAR), restorative low anterior resection (RLAR) and abdominoperineal resection (APR).Materials and methodsThis retrospective cohort included data from patients undergoing TME for rectal cancer between 2015 and 2017 in eleven Dutch hospitals. A comparison was made for each different type of procedure (APR, NRLAR or RLAR). Primary outcome was 3-year overall survival (OS). Secondary outcomes included 3-year disease-free survival (DFS) and 3-year local recurrence (LR) rate.ResultsOf 998 patients 363 underwent APR, 132 NRLAR and 503 RLAR. Three-year OS was worse after NRLAR (78.2%) compared to APR (86.3%) and RLAR (92.2%, p < 0.001). This was confirmed in a multivariable Cox regression analysis (HR 1.85 (1.07, 3.19), p = 0.03). The 3-year DFS was also worse after NRLAR (60.3%), compared to APR (70.5%) and RLAR (80.1%, p < 0.001), HR 2.05 (1.42, 2.97), p < 0.001. The LR rate was 14.6% after NRLAR, 5.2% after APR and 4.8% after RLAR (p = 0.005), HR 3.22 (1.61, 6.47), p < 0.001.ConclusionNRLAR might be associated with worse 3-year OS, DFS and LR rate compared to RLAR and APR. 相似文献
