OBJECTIVEIntraoperative seizures during craniotomy with functional mapping is a common complication that impedes optimal tumor resection and results in significant morbidity. The relationship between genetic mutations in gliomas and the incidence of intraoperative seizures has not been well characterized. Here, the authors performed a retrospective study of patients treated at their institution over the last 12 years to determine whether molecular data can be used to predict the incidence of this complication.METHODSThe authors queried their institutional database for patients with brain tumors who underwent resection with intraoperative functional mapping between 2005 and 2017. Basic clinicopathological characteristics, including the status of the following genes, were recorded: IDH1/2, PIK3CA, BRAF, KRAS, AKT1, EGFR, PDGFRA, MET, MGMT, and 1p/19q. Relationships between gene alterations and intraoperative seizures were evaluated using chi-square and two-sample t-test univariate analysis. When considering multiple predictive factors, a logistic multivariate approach was taken.RESULTSOverall, 416 patients met criteria for inclusion; of these patients, 98 (24%) experienced an intraoperative seizure. Patients with a history of preoperative seizure and those treated with antiepileptic drugs prior to surgery were less likely to have intraoperative seizures (history: OR 0.61 [95% CI 0.38–0.96], chi-square = 4.65, p = 0.03; AED load: OR 0.46 [95% CI 0.26–0.80], chi-square = 7.64, p = 0.01). In a univariate analysis of genetic markers, amplification of genes encoding receptor tyrosine kinases (RTKs) was specifically identified as a positive predictor of seizures (OR 5.47 [95% CI 1.22–24.47], chi-square = 5.98, p = 0.01). In multivariate analyses considering RTK status, AED use, and either 2007 WHO tumor grade or modern 2016 WHO tumor groups, the authors found that amplification of the RTK proto-oncogene, MET, was most predictive of intraoperative seizure (p < 0.05).CONCLUSIONSThis study describes a previously unreported association between genetic alterations in RTKs and the occurrence of intraoperative seizures during glioma resection with functional mapping. Future models estimating intraoperative seizure risk may be enhanced by inclusion of genetic criteria.

AbstractThis retrospective study was carried out to investigate factors affecting the prognosis of gliomas for better management of treatment. Clinical data from 186 glioma patients treated in our hospital from January 2013 to June 2016 were analyzed. There was slightly more male than female patients in the cohort. The main clinical symptoms included sudden limb twitching, headache and fatigue, vomiting, vision reduction and speaking disorders. The malignancy was high and the prognosis was poor in the patients, with an overall survival rate of 54.84 % by October 2017. Univariate analysis showed that the prognosis was mainly affected by age, tumor grade, preoperative Karnofsky performance status (KPS), surgical method, postoperative radiotherapy and chemotherapy, and postoperative use of temozolomide (TMZ). Multivariate Cox regression analysis showed that the independent risk factors for the prognosis were old age (≥ 60), advanced tumor, partial tumor resection, KPS of < 70, no chemotherapy after operation and < 4 courses of postoperative TMZ. The prognosis is negatively affected by age, tumor grade, KPS, and partial tumor resection. Surgical resection combined with chemotherapy and multi-course use of TMZ prolongs the survival time of patients.

The Impact

Background: Genetic alterations are increasingly being recognized to play an important role in both diagnosis and prognosis of MDS. In general, SF3B1 mutated MDS is known to have favorable outcomes whereas those with mutated TP53 have dismal survivals. However, it is unclear if the impact of these mutations applies to all subtypes of MDS including del(5q), a unique entity that is known for its sensitivity to lenalidomide and better prognosis. A prior study suggests TP53 mutations are associated with worse outcomes in del(5q) MDS (Jadersten et al. 2011), but a more recent study did not find this association and instead they showed SF3B1 mutants (MT) conferred shorter survival compared to wild-type (WT) (Meggendorfer et al. 2017). Herein, we describe our experience of del(5q) MDS patients and assess the prognostic impact of somatic mutations in this population. Methods: We retrospectively reviewed our database of 132 patients with del(5q) MDS who were treated at the Moffitt Cancer Center from 2001 to 2019. Sixty-three patients had molecular data available for analysis. Fisher's exact test of independence was used to determine significance for categorical variables. Univariate and multivariate analyses were conducted using log-rank and Cox regression, respectively. Kaplan-Meier analysis with log-rank test was used to estimate survival outcomes. Results: A total of 132 patients (47M/85F) with a median age of 70 at diagnosis were included in this analysis (Table 1). The majority had isolated del(5q) (86.3%) and the remaining with del(5q) plus other aberration(s) but not meeting criteria as complex cytogenetics. Among patients who received lenalidomide (n=98), 50%, 42.9%, and 7.1% achieved hematologic improvement (HI) or better, no response (NR), and disease progression (DP)/death with a median overall survival (OS) of 93.2, 72.4, and 25.6 months from the time of diagnosis, respectively (p&lt;0.0001) (Figure 1). The median OS of the entire cohort was 73.3 months (median follow-up of 131.3 months), and OS from the time patients stopped lenalidomide was only 26 months. Of the 63 patients with molecular data available, 23.8% were found to have TP53 mutations with a median variant allele frequency (VAF) of 20.4% and 10% SF3B1 MT (median VAF 38.9%). Other common mutations include TET2 (19%) and DNMT3A (17%) as shown in Figure 2. Interestingly, TP53 status did not impact OS (MT 86.4 vs. WT 73.3 months; p=0.72), but those with SF3B1 mutations had a significantly shorter median OS compared to WT (23.9 vs. 83.5 months; p=0.001) (Figure 3). When test for effects of multiple genes had on survival, no combinations were found to be predictive. Univariate analysis showed lenalidomide response significantly impacted OS (HI compared to NR: HR 0.19, 95% CI: 0.05-0.68, p=0.005). Multivariate regression confirmed lenalidomide response and SF3B1 status are independently associated with outcomes. Conclusions: SF3B1 mutations, typically correlate with favorable risk in MDS, are associated with significantly worse prognosis compared to WT in patients with del(5q) MDS. On the contrary, there was no significant difference in OS in patients with TP53 MT vs. TP53 WT. A substantial portion of patients benefited from lenalidomide; however, after lenalidomide failure survivals were limited. Despite the known overall associations between MDS and mutations such as SF3B1 and TP53, our data suggests the del(5q) subset behaves differently which adds to the heterogeneity of the disease. Further studies are needed to clarify the impact of treatments and somatic mutations on outcomes.

11 Background: Although metaplastic breast cancer (MBC) represents < 1% of breast cancer, stem cell research has stimulated interest in the genetics and biology of MBC. Because prognostic clinical and treatment factors remain ill-defined for this rare breast cancer subtype, we queried a public cancer data registry to identify factors predictive of overall survival (OS) in MBC. Methods: Patients diagnosed with breast cancer from 2001-2008 were identified using the Surveillance, Epidemiology, and End Results (SEER) database. We included only patients with infiltrating ductal carcinoma (IDC) and MBC who had non-metastatic disease. Patients were evaluated by standard demographic, clinicopathologic, and treatment factors including age, race/ethnicity, extent of disease, tumor marker expression and treatment received. Differences between IDC and MBC were assessed using Chi-Square methods. OS across groups was measured using the Kaplan-Meier method and compared using the log-rank test. Cox proportional hazard and stepwise models were used to identify prognostic variables and to adjust for covariates. Median follow-up was 31 months. Results: Of the total 508,071 breast cancer cases, there were 1,246 (0.25%) patients with MBC and 392,809 (77%) with IDC. 5-yr OS for locoregional MBC and IDC was 67% and 84%, respectively (p<0.0001). When compared with IDC, MBC patients were older, had larger ER/PR negative cancers, and were more likely to have nodal disease. Factors predictive of worse OS in MBC on multivariate analysis are listed below. Tumor grade, ER/PR expression, and type of surgery (partial v. total mastectomy) did not impact OS. Of the treatment factors, only radiation affected OS (p=0.0002). Conclusions: To our knowledge this is the largest report of clinical and treatment factors predictive of outcomes in patients with MBC. Studies integrating clinical factors with molecular data may advance therapy that is more specific for this rare breast cancer subtype. [Table: see text]

Background: Breast cancer is the most common cancer diagnosed in women worldwide. So it seems that there's a good chance of recovery if it's detected in its early stages even before the appearances of symptoms. Recent studies have shown that miRNAs play an important role during cancer progression. These transcripts can be tracked in liquid samples to reveal if cancer exists, for earlier treatment. MicroRNA-21 (miR-21) has been shown to be a key regulator of carcinogenesis, and breast tumor is no exception. Objective: The present study was aimed to track the miR-21 expression level in serum of the breast cancer patients in comparison with that of normal counterparts. Methods: Comparative real-time polymerase chain reaction was applied to determine the levels of expression of miR-21 in the serum samples of 57 participants from which, 42 were the patients with breast cancer including pre-surgery patients (n = 30) and post-surgery patients (n = 12), and the others were the healthy controls (n = 15). Results: MiR-21 was significantly over expressed in the serum of breast cancer patients as compared with healthy controls (P = 0.002). A significant decrease was also observed following tumor resection (P < 0.0001). Moreover, it was found that miR-21 overexpression level was significantly associated with tumor grade (P = 0.004). Conclusion: These findings suggest that miR-21 has the potential to be used as a novel breast cancer biomarker for early detection and prognosis, although further experiments are needed.

⋄ Objective Loss of residual renal function (RRF) in peritoneal dialysis (PD) patients is a powerful predictor of mortality. The present study was conducted to determine the predictors of faster decline of RRF in PD patients in Taiwan. ⋄ Methods The study enrolled 270 patients starting PD between January 1996 and December 2005 in a single hospital in Taiwan. We calculated RRF as the mean of the sum of 24-hour urea and creatinine clearance. The slope of the decline of residual glomerular filtration rate (GFR) was the main outcome measure. Data on demographic, clinical, laboratory, and treatment parameters; episodes of peritonitis; and hypotensive events were analyzed by Student t-test, Mann–Whitney U-test, and chi-square, as appropriate. All variables with statistical significance were included in a multivariate linear regression model to select the best predictors ( p < 0.05) for faster decline of residual GFR. ⋄ Results All patients commencing PD during the study period were followed for 39.4 ± 24.0 months (median: 35.5 months). The average annual rate of decline of residual GFR was 1.377 ± 1.47 mL/min/m2. On multivariate analysis, presence of diabetes mellitus ( p < 0.001), higher baseline residual GFR ( p < 0.001), hypotensive events ( p = 0.001), use of diuretics ( p = 0.002), and episodes of peritonitis ( p = 0.043) independently predicted faster decline of residual GFR. Male sex, old age, larger body mass index, and presence of coronary artery disease or congestive heart failure were also risk factors on univariate analysis. ⋄ Conclusions Our results suggested that diabetes mellitus, higher baseline residual GFR, hypotensive events, and use of diuretics are independently associated with faster decline of residual GFR in PD patients in Taiwan.

Abstract INTRODUCTION Renal cell carcinoma (RCC) represents 3% of overall malignant neoplasms in adults. However, its aetiology has not been clearly established. Although surgery represents the cornerstone in treatment, recurrence postoperative rates are around 20-30%, what implies prognostic factors search must be mandatory in order to help to plan de follow-up and the different adjuvant therapy possibilities available in case they were necessary. MATERIAL AND METHODS A retrospective observational study was carried out in 110 patients who underwent radical nephrectomy between 2004 and 2018, with the aim of identifying possible prognostic factors of recurrence of RCC after these surgeries. Preoperative data (epidemiological, comorbidities and laboratory tests), surgical, pathological and variables related to follow-up were taken into account. A univariate and multivariate analysis were performed, using chi-square test and logistic regression, respectively. RESULTS The median follow-up time was 53.5 months (SD = 35.8), time in which 19 patients had a recurrence of RCC after radical nephrectomy (17.2%). Histopathological items such as the surgical piece size, the nodal and microvascular invasion, the renal sinus invasion and the presence of necrosis in the surgical piece were associated with RCC recurrence in the univariate analysis, while only the presence of necrosis in the surgical piece showed a significant result in the multivariate analysis (p = 0.004). CONCLUSIONS Histopathological analysis, highlighting the presence of necrosis in the histological sample, was proved to be the main risk factor of RCC recurrence.

Metastatic Spine Tumor

OBJECTIVEResection of metastatic spine tumors can improve patients’ quality of life by addressing pain or neurological compromise. However, resections are often complicated by wound dehiscence, infection, instrumentation failures, and the need for reoperation. Moreover, when reoperations are needed, the most common indication is surgical site infection and wound breakdown. In turn, wound reoperations increase morbidity as well as the length and cost of hospitalization. The aim of this study was to examine perioperative risk factors associated with increased rate of wound reoperations after metastatic spine tumor resection.METHODSA retrospective study of patients at a single institution who underwent metastatic spine tumor resection between 2003 and 2013 was conducted. Factors with a p value < 0.200 in a univariate analysis were included in the multivariate model.RESULTSA total of 159 patients were included in this study. Karnofsky Performance Scale score > 70, smoking status, hypertension, thromboembolic events, hyperlipidemia, increasing number of vertebral levels, and posterior approach were included in the multivariate analysis. Thromboembolic events (95% CI 1.19–48.5, p = 0.032) and number of levels involved were independently associated with increased wound reoperation rates in the multivariate model. For each additional spinal level involved, the risk for wound reoperations increased by 21% (95% CI 1.03–1.43, p = 0.018).CONCLUSIONSAlthough wound complications and subsequent reoperations are potential risks for all patients with metastatic spine tumor, due to adjuvant radiotherapy and other medical comorbidities, this study identified patients with thromboembolic events or those requiring a larger incision as being at the highest risk. Measures intended to decrease the occurrence of perioperative venous thromboembolism and to improve wound care, especially for long incisions, may decrease wound-related revision surgeries in this vulnerable group of patients.
