The objective of this study was to compare perioperative outcomes and total and split renal function between laparoscopic partial nephrectomy (LPN) and robot-assisted partial nephrectomy (RAPN). Predictive risk factors of preservation of operated renal function were also assessed.
Methods
We retrospectively analyzed 173 patients who underwent LPN (n?=?84) or RAPN (n?=?89) between 2010 and 2020. After propensity score matching (1:1), perioperative outcomes and total and split renal function were assessed. Logistic regression analysis was used to evaluate predictive risk factors of preservation of operated renal function. Trifecta criteria were defined as negative surgical margins, warm ischemia time (WIT)?<?25 min, and no complications more than Clavien–Dindo grade II within 4 weeks after surgery. Split renal function was evaluated by mercaptoacetyltriglycine renal scan.
Results
After propensity score matching, 42 patients were allocated to each group. RAPN was associated with significantly shorter WIT (RAPN vs LPN: 12 vs 22 min; p?<?0.0001) and higher trifecta achievement rate (93.3 vs 64.2%; p?<?0.0001). Other perioperative outcomes and total and split renal function were not significantly different between LPN and RAPN. The R.E.N.A.L. nephrometry score (RNS) was a predictive risk factor of preservation of operated renal function in the multivariable logistic regression analysis (odds ratio 1.68, 95% confidence interval 1.29–2.20, p?<?0.0001).
Conclusions
RAPN improved WIT and trifecta achievement rate, but it did not improve the preservation of operated renal function, for which RNS was found to be a strong predictive risk factor.
Inflammation-based markers predict the long-term outcomes of various malignancies. We investigated the relationship between the modified Glasgow prognostic score (mGPS) and the long-term outcomes of obstructive colorectal cancer in patients who underwent self-expandable metallic colonic stent placement and subsequently received curative surgery. We retrospectively analyzed 63 consecutive patients with pathological stage II and III obstructive colorectal cancer from 2013 to 2018. The mGPS was calculated before stenting and surgery, and the difference of the scores was defined as the d-mGPS. All d-mGPS = 2 patients were > 70 years of age (p = 0.01). Postoperative complications were more common in the preoperative mGPS = 2 group (p = 0.02). The postoperative hospital stay was significantly longer in the mGPS = 2 group (p = 0.007). Multivariate analyses revealed that d-mGPS was an independent prognostic factor for overall survival (OS) (hazard ratio [HR] = 9.18, p = 0.004) and cancer-specific survival (HR = 9.98, p = 0.01). Preoperative mGPS = 2 was significantly associated with poor OS (HR = 5.53, p = 0.04). The results indicated that mGPS might serve as a valuable indicator of the immunonutritional status of preoperative patients, and a preoperative change of the status might affect the long-term outcomes of patients with obstructive colorectal cancer. 相似文献
Previously, we reported the isolation of cassane-type diterpenes, sucutiniranes A–F, from the seeds of Bowdichia nitida. In this study, a series of sucutinirane derivatives was prepared, and their in vitro toxicity in the HL-60 cell line was evaluated. Then the action mechanism of a representative compound that induces cell death was investigated. Whereas C-6 or C-7 diol esters and ether decreased the activity against the HL-60 cell line, furan-oxidized derivatives 12 and 13 showed improvement or retention of the activity compared with those of the natural products sucutinirane A (11), E (1), and F (2). Treatment with sucutinirane derivative 13 elevated caspase 3/7 activity and also decreased expression of Bcl-2 family proteins, Mcl-1, and Bid. Derivative 13 generated reactive oxygen species in HL-60 cells, whose apoptotic effects were attenuated by the addition of an antioxidant, N-acetyl-l-cysteine. These results suggest that cassane butenolide 13 induces apoptosis in HL-60 via its oxidative effects. 相似文献
Recent studies have shown that the modified Glasgow Prognostic Score (mGPS), which is an inflammation-based prognostic score, is useful as a prognostic index for some cancer cases. The purpose of this study was to create a prognostic scoring system for patients with esophageal squamous cell carcinoma (ESCC) that was more independent and sensitive than the mGPS.
Methods
One hundred sixty-eight patients who had undergone esophagectomy for ESCC were included in the study. The new mGPS (NmGPS) was calculated based on the following cutoff values: CRP >0.75 mg/dL indicated NmGPS 1 or 2, depending on the absence or presence of hypoalbuminemia (<3.5 g/dL); and CRP ≤0.75 mg/dL indicated NmGPS 0. We also performed an analysis based on cutoff values of 0.5 and 0.25 mg/dL for CRP.
Results
Only the NmGPS with a cutoff CRP value of 0.5 mg/dL was able to divide into three independent patient groups in the survival curves. In the multivariate analyses, a NmGPS (CRP cutoff; 0.5 mg/dL) of 2 was a more significant independent prognostic factor (HR 4.437, 95 % CI 2.000–9.844, p = 0.0002) than a mGPS of 2 (HR 2.726, 95 % CI 1.021–7.112, p = 0.0449).
Conclusions
The new prognostic score NmGPS (CRP cutoff; 0.5 mg/dL) was more independent and sensitive than the mGPS for patients with ESCC. 相似文献
Meningeal carcinomatosis is a well‐known complication of malignant neoplasms. We report a case of meningeal carcinomatosis of 2 months' duration in a 22‐year‐old man, in whom the initial symptom was gradually worsening headache. Postmortem examination revealed infiltrating adenocarcinoma of the stomach. Carcinoma cells showed diffuse spread to the subarachnoid space of the brain and spinal cord. In many places, subarachnoid tumor cells had infiltrated to the cranial and spinal nerves. Moreover, carcinoma cells in the nerve roots extended to the parenchyma of the brain and spinal cord beyond the CNS‐peripheral nervous system junction. These findings suggest that cranial and spinal nerve roots can be a possible route of parenchymal invasion in meningeal carcinomatosis. 相似文献
Aims/IntroductionSodium–glucose cotransporter 2 inhibitors (SGLT2i) improve renal outcome in patients with type 2 diabetes mellitus, but the mechanism is not fully understood. The aim of this retrospective study was to assess the association of achieved blood pressure with renal outcomes in Japanese type 2 diabetes mellitus patients with chronic kidney disease.Materials and MethodsWe assessed 624 Japanese type 2 diabetes mellitus patients with chronic kidney disease taking SGLT2i for >1 year. The patients were classified as those with post‐treatment mean arterial pressure (MAP) of ≥92 mmHg (n = 344) and those with MAP of <92 mmHg (n = 280) for propensity score matching (1:1 nearest neighbor match with 0.04 of caliper value and no replacement). The end‐point was a composite of progression of albuminuria or a decrease in the estimated glomerular filtration rate by ≥15% per year.ResultsBy propensity score matching, a matched cohort model was constructed, including 201 patients in each group. The incidence of renal composite outcome was significantly lower among patients with MAP of <92 mmHg than among patients with MAP of ≥92 mmHg (n = 11 [6%] vs n = 26 [13%], respectively, P = 0.001). The change in estimated glomerular filtration rate was similar in the two groups; however, the change in the albumin‐to‐creatinine ratio was significantly larger in patients with MAP of <92 mmHg.ConclusionsIn Japanese type 2 diabetes mellitus patients with chronic kidney disease, blood pressure after SGLT2i administration influences the renal composite outcome. Blood pressure management is important, even during treatment with SGLT2i. 相似文献
To assess the relationship between venous thrombosis and plasma glucosylceramide (GlcCer) or phosphatidylethanolamine (PE), plasma levels of GlcCer and PE were determined for 70 venous thrombosis patients referred for evaluation and 70 healthy blood donors. The mean GlcCer level, but not the PE level, was lower in patients versus controls (4.9 vs 6.5 microg/mL [P =.0007] and 66 vs 71 microg/mL [P =.48], respectively). As a measure of relative risk, the odds ratio for deep vein thrombosis in subjects with GlcCer levels below the 10th percentile of controls was 5.7 (95% CI, 2.3-14). To assess the influence of glycolipids on anticoagulant response to activated protein C (APC):protein S in modified prothrombin time assays, the effects of depleting endogenous plasma GlcCer by glucocerebrosidase treatment or of adding exogenous purified GlcCer or other neutral glycolipids to plasma were tested. Glucocerebrosidase treatment reduced plasma sensitivity to APC:protein S in parallel with GlcCer reduction. Exogenously added GlcCer and the homologous Glc-containing globotriaosylceramide (Gb3Cer), but not galactosylceramide, dose-dependently prolonged clotting times of normal plasma in the presence, but not absence, of APC:protein S, which suggests that GlcCer or Gb3Cer can enhance protein C pathway anticoagulant activity. In studies using purified proteins, inactivation of factor Va by APC:protein S was enhanced by GlcCer alone and by GlcCer in multicomponent vesicles containing phosphatidylserine and phosphatidylcholine. These results suggest that the neutral glycolipids GlcCer and Gb3Cer may directly contribute to the anticoagulant activity of the protein C pathway and that deficiency of plasma GlcCer may be a risk factor for venous thrombosis.

Hepatocellular carcinoma may manifest various paraneoplastic syndromes. There are some reports describing hematological change due to hepatocellular carcinoma. However, there have been no reports on hepatocellular carcinoma accompanied by hemophagocytic syndrome. We report here for the first time a 51-year-old man with a liver tumor and pancytopenia. Since the patient had showed a strong hemorrhagic diathesis because of thrombocytopenia, we treated him with blood transfusion, but there was no response. Thereafter, we administered the anticancer agents thinking that the hematological change was due to the liver tumor. Though a slight curative effect was obtained, we had to discontinue the treatment because the patient complained of severe side effects. Finally, the patient died of acute cholangitis. Although we could not determine the cause of the pancytopenia before he died, autopsy findings indicated that hemophagocytic syndrome had occurred. Hemophagocytic syndrome related to a solid tumor very rarely occurs. However, when malignant tumor is accompanied by pancytopenia, hemophagocytic syndrome should be considered. 相似文献
