Abstract INTRODUCTION We retrospectively analyzed the impact on post-relapse survival of selected prognostic factors and salvage therapy (finalized to perform an allo-SCT) in 145 patients (pts) with non-APL AML who had been initially treated with standard induction and risk-adapted consolidation. The aim was to identify factors associated with a better outcome at first relapse. METHODS All pts were at first recurrence following consolidation of CR1 with (i) high-dose Ara-C (HiDAC) multicycle therapy supported by blood stem cells (standard risk, as defined by mixed clinico-cytogenetic criteria) or (ii) allo-SCT in case of high-risk prognostic profile. Median pt age was 55 y (range 21–68). CR1 duration was ≤ 6 months in 49 pts (34%), ranging from 0.6 to 6 mo (median 3.7). 25/68 pts (37%) had an unfavourable cytogenetics (CG), and 8.2 % had MDS-related AML. 96 pts (66%) had received HiDAC and 21 (15%) an allo-SCT according to study design. RESULTS 105 pts (72%) received salvage chemotherapy, 10 pts (7%) underwent directly allo-SCT, while the remaining 30 (21%) received palliation and all of them died. Salvage therapy consisted again of HiDAC alone or in combination with fludarabine or anthracyclines. After reinduction, 52/105 pts (49.5%) achieved CR2 and 15 (14%) died of complications. Altogether, 42 pts (29%, group 1) received an allo-SCT following relapse, 27 (64%) in CR2, 5 beyond CR2 and 10 soon after relapse. Of 20 more pts (14%, group 2) in CR2 but without HLA identical donor, 13 could be given further intensive consolidation therapy. Both groups were comparable regarding adverse prognostic features such as age >55 y, WBC count>50,000/μL, unfavourable CG, presence of FLT-3 ITD, prior allo-SCT and 1st CR lasting ≤ 6 mo. At the end of treatment, 37/42 pts (88%) receiving SCT and all 20 pts (100%) given only chemotherapy were in CR2. Logistic regression analysis showed that intensive treatment without HiDAC at induction (p=0.04) as well as CR1 lasting <6 mo (p=0.01) negatively affected CR2 rate. Median duration of CR2 was 7.5 mo (range 1–49) in group 1 compared to 4 mo (range 1–15) in group 2. Day 100 non-relapse mortality in the 2 groups was 7% and 10%. After a median follow-up of 9.4 mo in group 1 (range 3–49) and 10 mo in group 2 (range 2–65), 2-y OS was 24% and 15.5%, respectively. Notably, 2-y OS in allo-SCT group ranged from 42% in pts ≤ 45 years to 14% in older ones. Moreover, survival was affected by risk category. In fact 2-y OS of 14/37 (38%) standard risk pts undergoing allo-SCT at salvage was 41% vs 17% in 28/108 (26%) comparable high risk pts. Cox regression analysis revealed achievement of CR2 being the only independent prognostic factor related to overall survival (p=0.0001). CONCLUSIONS AML patients receiving intensive chemotherapy including HiDAC at 1st relapse reached a high CR2 rate, regardless of type of prior risk-adapted consolidation. Further intensification with allo-SCT may offer substantial salvage rates to younger standard risk patients, thus adding value to the underlying concept of a risk-oriented first-line therapy.

Abstract Some data suggest that there are been no improvement in survival of FL Pts in the last three decades of the 20th century. However that review ended in 1992, before the introduction of R treatment. Most recently reported data, show that evolving chemotherapies, including the incorporation of R has led to outcome improvement. Between 1994 and 2004, 344 Pts with FL were enrolled in different GISL Trials. For the purpose of this study we considered 270 Pts with similar characteristics enrolled in trials including or not R. The first group accounts for 176 naive Pts treated with Antracycline plus Fludarabine containing regimens (Cohort #1: 125 Pts) or plus R (Cohort #2: 51Pts). The second group accounts for 99 relapsed Pts treated with Antracycline plus Fludarabine containing regimens (Cohort #3: 40 Pts) or plus R (Cohort #4: 59 Pts). To evaluate the impact of the incorporation of R in front line and salvage therapies we assessed the patients OS, FFS, TTF, SAR in these different Cohorts of Pts. Descriptive analysis of prognostic features showed differences in the distribution among groups. To compensate for these variations we also performed Cox regression analysis. Previously Untreated patients. Regarding group #1 and #2 that enrolled Pts with clinical stage IIB, III and IV, FFS and OS according to treatment did not show any statistical differences. The univariate analysis of baseline clinical features showed an impact on OS and FFS for clinical stage, LDH level, involvement of more than 4 nodal sites and presence of extranodal involvement. The prevalence of this characteristics were higher in group #2 than group #1. Thus the FFS from group #2 vs. group #1 was adjusted for variation in prognostic features by Cox regression analysis, that shows a failure Hazard Radio reduction (HR) of 40 % in Pts who received R. Because of difference in follow up (FU) (49 months in Cohort #1 vs 21 months in Cohort #2), to evaluate differences in OS we utilized exact Log Rank test for unequal FU. So far, a trend exists for better OS in R treated patients, although the difference is not statistically significant. Relapsed Patients. Clinical characteristics were similar in the two Cohorts of pts. TTF was better in R treated Pts and the difference was statistically significant (66% vs. 53% at 3 yrs, p=0.023) The analysis of SAR demonstrated a better result for R Cohort with a statistically significant difference (88% vs. 68% at 3 yrs, p=0.022). OS according to treatment protocol, showed advantage for patients in R Cohort and the difference was statistically significant (92% vs. 70% at 5 yrs, p=0.004). Conclusion. In naïve patients our retrospective analysis showed a reduction of HR for FFS and a trend toward better OS in R treated Pts. In relapsed Pts all outcome parameters as OS, TTF and SAR had significant improvement in the Cohort treated with R. Although any conclusions between nonrandomized groups maybe subject to differences in observed and unobserved prognostic features, we believe that improvement have occurred in the management of FL Pts with the introduction of combined chemotherapy with R.

Abstract INTRODUCTION The impact on post-relapse survival of selected prognostic factors and salvage therapy (finalized to perform an allo-SCT) was retrospectively analyzed in 172 patients (patients) with relapsed non-APL AML, who had been initially treated with standard induction and risk-adapatiented consolidation. The aim was to identify factors associated with a better outcome at first relapse. METHODS All 172 patients were at first recurrence following consolidation of CR1 with high-dose Ara-C (HiDAC) multicycle therapy supported by blood stem cells (standard risk, as defined by mixed clinical-cytogenetic criteria) or allo-SCT in case of high-risk prognostic profile. Median age at relapse was 55 y (range 21–70). CR1 duration was &lt;6 months in 50 patients (29%), ranging from 0.6 to 52,7 mo (median 9,1). High risk patients were 128/172 (74%) and 43/172 patients (25%) had an unfavourable cytogenetics (CG). One hundred-eleven patients (64%) received HiDAC and 24 (14%) an allo-SCT according to study design. RESULTS 140 patients (81%) received salvage treatment. The remaining 32 patients (19%) received palliation and all of them died. The median OS was 17.1 mo, with a 2yOS of 34%. Favorable prognostic factors identified by univariate analisys were: favourable or intermediate CG (p=0,007), standard risk category according to first line protocol (p=0.004), availibility of a HLA matched donor (p= 0.048), achievement of an early CR1(p=0,000), HiDAC as first line therapy(p=0,000), alloHSCT perfomed at relapse (p=0,000) and a DFS from CR1&gt;12 mo (p=0,000). In multivariate analysis favourable or intermediate CG and DFS &gt;12 mo were confirmed as independent prognostic factors (p=0,036 and p=0,001 respectively). Among the 140 patients, 50 received an allo-SCT following relapse (36%, group 1), and the remaining 90 (64%, group 2) received high dose chemotherapy alone (85), autologous SCT (2), or DLI (3, in case of previous alloSCT). Both groups were comparable regarding age &gt;55 y, prior allo-SCT and risk class at diagnosis. After salvage therapy, 44 patients(88%) in the group 1 achieved CR2, compared to 26 patients (29%) in the group 2. The median duration of CR2 was 9 mo (range 2–64) and 3 mo (range 1–34) in group 1 and 2 respectively. NRM was 17/140: 12 patients (24%) in the allo-SCT group and 5 (6%) in group 2. The 2yOS was 57% and 23% respectively (p=0,000). Moreover, among 50 alloSCT patients, survival was affected by risk category at diagnosis: 2yOS of 19 (38%) standard risk patients was 83% compared to 42% in 31 high risk patients (62%) (p=0.01). This risk stratification has no impact on OS in the group 2. CONCLUSIONS DFS &gt; 12 mo and standard risk category at diagnosis, according to NILG protocol, are the most important independent positive prognostic factors impacting OS of AML relapsed patients. The availibility of a HLA matched donor and a subsequent intensification with alloSCT may offer substantial salvage rates and its outcome is affected by the risk stratification at diagnosis. Nevertheless, high risk patients could benefit from alloSCT, reaching an 2yOS of 42%.

Aims Guided growth has been used to treat coxa valga for cerebral palsy (CP) children. However, there has been no study on the optimal position of screw application. In this paper we have investigated the influence of screw position on the outcomes of guided growth. Methods We retrospectively analyzed 61 hips in 32 CP children who underwent proximal femoral hemi epiphysiodesis between July 2012 and September 2017. The hips were divided into two groups according to the transphyseal position of the screw in the coronal plane: across medial quarter (Group 1) or middle quarter (Group 2) of the medial half of the physis. We compared pre- and postoperative radiographs in head-shaft angle (HSA), Reimer’s migration percentage (MP), acetabular index (AI), and femoral anteversion angle (FAVA), as well as incidences of the physis growing-off the screw within two years. Linear and Cox regression analysis were conducted to identify factors related to HSA correction and risk of the physis growing-off the screw. Results A total of 37 hips in Group 1 and 24 hips in Group 2 were compared. Group 1 showed a more substantial decrease in the HSA (p = 0.003) and the MP (p = 0.032). Both groups had significant and similar improvements in the AI (p = 0.809) and the FAVA (p = 0.304). Group 1 presented a higher incidence of the physis growing-off the screw (p = 0.038). Results of the regression analysis indicated that the eccentricity of screw position correlated with HSA correction and increases the risk of the physis growing-off the screw. Conclusion Guided growth is effective in improving coxa valga and excessive femoral anteversion in CP children. For younger children, despite compromised efficacy of varus correction, we recommend a more centered screw position, at least across the middle quarter of the medial physis, to avoid early revision.

Abstract Abstract 3540 Historically, allogeneic hematopoietic cell transplantation (HCT) has been offered only to patients with good performance status and below the age of 60. However, the peak incidence of most hematologic malignancies is above 60 years of age. The introduction of reduced intensity conditioning (RIC) regimens enabled successful allogeneic HCT in patients with considerable comorbidities and older than 60 years. The impact of age on outcome of allogeneic HCT in patients ≥60 years has not been evaluated extensively. We retrospectively analyzed 109 consecutive patients (f=43, m=66) aged≥60 who received allogeneic HCT 2000–2010 at our institution. Median age of the patients was 65 years (range, 60–76). Patients were grouped in two cohorts depending on age: group 1 aged 60–65 years (n=60, median age=63) and group 2 aged 66–76 years (n=49, median age=68). Diagnoses were acute leukemia (AML n=65, ALL n=1), myelodysplastic syndrome (n=14), osteomyelofibrosis (n=7), non-Hodgkin lymphoma (n=9), multiple myeloma (n=8), aplastic anemia (n=1), chronic myeloid leukemia (n=2) and chronic lymphatic leukemia (n=2). At time of HCT, 41 of the patients were in complete remission (CR), 68 in partial remission (PR) (group 1: CR 21, PR 39; group 2: CR 20, PR 29) and 18 patients had a preceding HCT, 14 in group 1. Conditioning regimens were grouped in high (TBI/Bu+Cy, n=5, all group 1), intermediate (FLAMSA, Flu/Mel/BCNU, n=28, group 1=11, group 2=17), low (FLU+alkylans, n=48, group 1=32, group 2=16) and minimal (2GyTBI/Flu, n=28, group 1=12, group 2=16) intensity. Intermediate intensity conditioning was particularly used for high risk patients in PR (25/28). 22 patients were transplanted from matched related (MRD), 46 from matched unrelated (MUD) and 41 from mismatched unrelated donors (MMUD). Kaplan-Meier-estimated 3-year overall survival (OS) was 45% for all patients, 32% for group 1 and 62%, for group 2, respectively (p=0.02), with more patients with high risk constellation in group 1. 3-year OS for patients transplanted with MUD was 57%, with MMUD 46% vs. with MRD 0% (p=0.01). Non-relapse-mortality was 28% for all patients, 40% in group 1 and 12% in group 2, probably due to the higher intensity in conditioning in group 1. The outcomes with intermediate, low and minimal intensity conditioning were comparable, while all patients after high intensity conditioning died. Table 1 describes Kaplan-Meier estimated 3-year-OS and statistical univariate analysis by log-rank test in the different subgroups. Table 1. 3-year OS (in%) All Group 1 Age 60–65 Group 2 Age 66–76 Remission CR 52 p=0.25 31 p=0.76 77 p=0.15 PR 40 32 50 Conditioning high 0 p=0.5 0 p=0.08 – p=0.38 intermediate 52 50 53 low 48 43 57 minimal 45 17 67 Donor MRD 0 p=0.01 0 p=0.06 73 p=0.45 MUD 57 53 65 MMUD 46 40 33 GVHD acute no 18 p=0.003 13 p=0.008 33 p=0.27 ≥II 43 53 58 chronic no 39 p=0.25 36 p=0.70 52 p=0.08 limited 52 30 100 extensive 50 30 67 In group 1 the outcome of minimal conditioning was inferior compared to intermediate and low conditioning while patients in group 2 had a better outcome with minimal vs. low and intermediate conditioning. Incidences of acute GVHD ≥II, limited and extensive chronic GVHD (cGVHD) were 10%, 28% and 13%, respectively. In group 1, acute GVHD ≥II occurred in 13% and cGVHD in 35%, in group 2 in 5% and 41% of the patients, respectively. Acute GVHD ≥II was associated with inferior outcome (3-year OS of 18% vs. 43%, p=0.003) while cGVHD had a positive impact on OS. In group 2 patients with limited cGVHD showed better 3-year OS than patients without cGVHD (67% vs. 52%, p=0.12). Age alone had no major impact on outcome of allogeneic HCT. Patients aged ≥60 seemed to benefit from the use of MUD rather than an older MRD. Chronic GVHD had a positive influence on survival. Our data indicate that the regimen used should be tailored to disease risk and patient performance status. Disclosures: No relevant conflicts of interest to declare.

ABSTRACT OBJECTIVE Stereotactic radiosurgery (SRS) has become an effective therapeutic modality for the treatment of patients with glioblastoma multiforme (GBM). This retrospective review evaluates the impact of SRS delivered on a gamma knife (GK) unit as an adjuvant therapy in the management of patients with GBM. METHODS Between August 1993 and December 1998, 82 patients with pathologically confirmed GBM received external beam radiotherapy (EBRT) at the University of Maryland Medical Center. Of these 82 patients, 64 with a minimum follow-up duration of at least 1 month are the focus of this analysis. Of the 64 assessable patients, 33 patients were treated with EBRT alone (Group 1), and 31 patients received both EBRT plus a GK-SRS boost (Group 2). GK-SRS was administered to most patients within 6 weeks of the completion of EBRT. The median EBRT dose was 59.7 Gy (range, 28–70.2 Gy), and the median GK-SRS dose to the prescription volume was 17.1 Gy (range, 10–28 Gy). The median age of the study population was 50.4 years, and the median pretreatment Karnofsky performance status was 80. Patient-, tumor-, and treatment-related variables were analyzed by Cox regression analysis, and survival curves were generated by the Kaplan-Meier product limit. RESULTS Median overall survival for the entire cohort was 16 months, and the actuarial survival rate at 1, 2, and 3 years were 67, 40, and 26%, respectively. When comparing age, Karnofsky performance status, extent of resection, and tumor volume, no statistical differences where discovered between Group 1 versus Group 2. When comparing the overall survival of Group 1 versus Group 2, the median survival was 13 months versus 25 months, respectively (P = 0.034). Age, Karnofsky performance status, and the addition of GK-SRS were all found to be significant predictors of overall survival via Cox regression analysis. No acute Grade 3 or Grade 4 toxicity was encountered. CONCLUSION The addition of a GK-SRS boost in conjunction with surgery and EBRT significantly improved the overall survival time in this retrospective series of patients with GBM. A prospective, randomized validation of the benefit of SRS awaits the results of the recently completed Radiation Therapy Oncology Group's trial RTOG 93-05.

Abstract Background Myelodysplastic syndromes (MDS) comprise a heterogeneous group of clonal myeloid disorders characterized by marrow failure and variable risk for acute leukemia transformation. The revised International prognostic scoring system (R-IPSS) biologically defines 5 risk disease categories and assists in logistic outcome prediction and treatment algorithm. For those patients (pts) with high risk MDS, treatment with hypomethylating agents (HMAs) such as azacitidine (AZA) and decitabine (DAC) is associated with prolonged survival. However primary and secondary treatment failures are common phenomenon and treatment outcomes after failure are dismal (Prebet T et al. JCO. 2011; Prebet T. Haematologica.2013). Mechanisms of loss of response to azanucleosides are largely unknown. Cytogenetic evolution (CE) defined as the acquisition of additional clones or karyotypic abnormalities in pts with preexisting normal or aberrant karyotype, during disease course or after treatment, is observed in about 30% of MDS patients, and is linked to genomic instability resulting in adverse outcomes. We investigated risk factors for CE in MDS pts treated with HMAs and its impact of OS. Method From 2000-2012, 13/124 pts (16%) (Median age 59 years; range 54-80) with confirmed diagnosis of MDS treated with HMAs were identified from the Michael E. Medical Center Cancer Registry. Patients were included if at least 2 G-banding metaphases studies were available and corresponded to: (1) karyotyping at disease diagnosis; and (2) at the time of azanucleoside failure. Overall Survival (OS) was analyzed for pts who have received HMAs with and without evidence of CE. Multivariate Cox regression analysis was performed to assess the impact of multiple independent variables on clinical outcome. Results The incidence of CE in patients treated with HMAs was 38%. Median R-IPSS scores at diagnosis for pts with and without CE were 7.5 (5-very high; WHO subgroups: RCMD [2] and RAEB-2 [3]) vs. 4.75 (4-high and 4-Int; WHO subgroups: RCMD [3], RCUD [1] CMML [2]; MDS/MPN [2]) P=0.003. OS for pts with and without CE treated with HMAs was 419 days (d) vs 743 d, respectively P=0.001;CI= 0.23-0.89. In patients with CE, univariate analysis identified platelets and blast count at disease initiation (P=0.03, each) as prognostic variables impacting clinical outcome; however, by multivariate analysis a non-statistically significant trend was observed only for R-IPSS, P=0.21. (Table 1). Conclusion In our retrospective analysis, acquisition of CE at the time of azanucleoside failure was associated with unfavorable outcome. Exploratory logistic regression analysis suggests that high-risk disease biology at disease initiation modulates incidence of CE in MDS pts treated with azanucleosides. Larger coalesced cohort of MDS pts experiencing CE could facilitate understanding of mechanisms associated with acquisition of genomic instability during azanucleoside failure and assist in identification of novel MDS targeted therapies that could ensure sustained response.

Abstract Introduction. Conventional induction treatment in young non APL-Acute Myeloid Leukemia (AML) patients is still represented by the association of an antracycline and Cytarabine, which offers a complete remission (CR) rate not inferior to 60%. The addition of Gemtuzumab Ozogamicin (GO) as a third or fourth drug, already demonstrated to improve clinical outcome, in terms of CR rates. Aims of the study. We retrospectively evaluated and compared the efficacy of different induction schedules, in terms of CR rates and Overall Survival (OS), administered to two groups of AML patients. Group 1 (n=139) was treated with a GO containing course (MyFLAI or MyAIE schedules); Group 2 (n=270) received a non-GO based regimen including or not Fludarabine (FLAI, FLAN, FLAG, 3+7 or DAE). Patients and Methods. From 1997 to 2014,409 newly diagnosed AML patients were treated in 3 Italian Institutions. Their median age was 53 (range 19-74) and 52 (range 17-75) years, respectively. According to karyotype (performed in 392/409 patients), FLT3 (available for 244/409 patients), and NPM1 mutational status (available for 157/409 patients), based on the NCCN-2013 risk stratification criteria, 35.2% of the patients were considered at High Risk (HR) (31.6% and 36.4% in the two groups, respectively) and 7.6% at low risk (LR) (7.8% and 7.0%, respectively). Results. The complete remission (CR) rate after induction was 81.4% and 70.4% for Group 1 and 2, respectively (p=0.01). Deaths during induction (DDI), occurring in the first 50 days from 1st line therapy, were 4/139 (2.9%) in Group 1 and 22/270 (8.1%) in Group 2 (p=0.003). Patients treated with GO showed a better OS than patients of Group 2 (Figure 1); the 5-years OS in the two groups was 54.01% and 34.9%, respectively, and different according to age (54.0% and 34.9% respectively (p=0.0003) in patients <60 years, 30.2% and 13.5% respectively (p=0.001) in patients ³60 years). The 5-years Event Free Survival (EFS) in the two groups was 45.6% and 30.8% respectively (p=0.0003) (Figure 2). Then, with a logistic univariate regression analysis.,we explored the impact of GO therapy in terms of CR rate. The use of GO was identified as a strong predictor of the achievement of a 1st CR (p=0.008). Moreover, a logistic multivariate regression analysis (risk and age) confirmed the role of the compound as a predictor of higher CR rate (p=0.013). We also performed a Cox Regression analysis, to investigate the impact of GO therapy, age and risk on OS: the use of GO was confirmed to be an independent predictor of better OS (p<0.0001) with a Hazard Ratio of 1.966 (p<0.0001). In a sub-analysis performed on HR patients, we observed a significantly better outcome in Group 1 than in Group 2 in terms of OS (p=0.0074, 5-year OS 47.7%; in group 2 OS 21.0% respectively, Figure 3) and EFS (p=0.001). However, there was no difference in terms of CR rate (p=ns). In particular, HR patients with adverse karyotype, may benefit from GO induction therapy in terms of OS (5-years OS 42.9% and 12.8% in Group 1 and 2, respectively, p=0.02); nevertheless FLT3 mutations negative impact canÕt be overcome by the drug administration (5-years OS 66.6% and 61.3% in Group 1 and 2, respectively). In SR AML, GO offered a better OS (p=0.036, 5-years OS 51.4% and 41.9% respectively). Comparing with Fisher's exact test the rate of increment in 5-years OS between Group1 and Group2 in HR and SR AML, we demonstrate that treatment with GO gave the higher benefit in HR AML (p=0.0005). Conclusions. These data showed that a four-drugs intensified induction therapy is a feasible approach in AML patients: adding GO at any induction regimen is an independent and strong predictor of better OS and higher CR rates. In our population, GO was not associated with a higher incidence of DDI. This approach, could be strongly recommended in SR and HR AML patients, due to karyotype abnormalities, in which showed an advantage in term of OS if compared with other standard regimens. On the contrary, we donÕt suggest the same schedule in FLT3 mutated patients, in which no benefits have been observed.

AbstractShort CommunicationsEXIT (ex-utero intrapartum treatment) procedure is a fetal survival-increasing modification of cesarean section. Previously we found an increase incidence of fetal vascular malperfusion (FVM) in placentas from EXIT procedures which indicates the underlying stasis of fetal blood flow in such cases. This retrospective analysis analyzes the impact of the recently introduced CD34 immunostain for the FVM diagnosis in placentas from EXIT procedures.Objectives and MethodsA total of 105 placentas from EXIT procedures (48 to airway, 43 to ECMO and 14 to resection) were studied. In 73 older cases, the placental histological diagnosis of segmental FVM was made on H&E stained placental sections only (segmental villous avascularity) (Group 1), while in 32 most recent cases, the CD34 component of a double E-cadherin/CD34 immunostain slides was also routinely used to detect the early FVM (endothelial fragmentation, villous hypovascularity) (Group 2). 23 clinical and 47 independent placental phenotypes were compared by χ2 or ANOVA, where appropriate.ResultsThere was no statistical significance between the groups in rates of segmental villous avascularity (29 vs. 34%), but performing CD34 immunostain resulted in adding and/or upgrading 12 more cases of segmental FVM in Group 2, thus increasing the sensitivity of placental examination for FVM by 37%. There were no other statistically significantly differences in clinical (except for congenital diaphragmatic hernias statistically significantly more common in Group 2, 34 vs 56%, p=0.03) and placental phenotypes, proving the otherwise comparability of the groups.ConclusionsThe use of CD34 immunostain increases the sensitivity of placental examination for FVM by 1/3, which may improve the neonatal management by revealing the increased likelihood of the potentially life-threatening neonatal complications.

Abstract Background The aim of this retrospective comparative study was to assess the impact of COVID-19 and delayed emergency department access on emergency surgery outcomes, by comparing the main clinical outcomes in the period March–May 2019 (group 1) with the same period during the national COVID-19 lockdown in Italy (March–May 2020, group 2). Methods A comparison (groups 1 versus 2) and subgroup analysis were performed between patients’ demographic, medical history, surgical, clinical and management characteristics. Results Two-hundred forty-six patients were included, 137 in group 1 and 109 in group 2 (p = 0.03). No significant differences were observed in the peri-operative characteristics of the two groups. A declared delay in access to hospital and preoperative SARS-CoV-2 infection rates were 15.5% and 5.8%, respectively in group 2. The overall morbidity (OR = 2.22, 95% CI 1.08–4.55, p = 0.03) and 30-day mortality (OR = 1.34, 95% CI 0.33–5.50, =0.68) were significantly higher in group 2. The delayed access cohort showed a close correlation with increased morbidity (OR = 3.19, 95% CI 0.89–11.44, p = 0.07), blood transfusion (OR = 5.13, 95% CI 1.05–25.15, p = 0.04) and 30-day mortality risk (OR = 8.00, 95% CI 1.01–63.23, p = 0.05). SARS-CoV-2-positive patients had higher risk of blood transfusion (20% vs 7.8%, p = 0.37) and ICU admissions (20% vs 2.6%, p = 0.17) and a longer median LOS (9 days vs 4 days, p = 0.11). Conclusions This article provides enhanced understanding of the effects of the COVID-19 pandemic on patient access to emergency surgical care. Our findings suggest that COVID-19 changed the quality of surgical care with poorer prognosis and higher morbidity rates. Delayed emergency department access and a “filter effect” induced by a fear of COVID-19 infection in the population resulted in only the most severe cases reaching the emergency department in time.

Abstract INTRODUCTION Children treated for CNS tumours experience a very high burden of adverse effects. Platinum-based chemotherapy and cranial radiotherapy can cause ototoxicity, which may be particularly problematic in patients who have impaired vision and cognition as a result of their tumour and associated treatment. This study assessed the prevalence of impaired hearing and vision and how this may impact upon education. METHODS 53 patients diagnosed with solid tumours in Edinburgh, UK between August 2013–2018 were included in the study. Patients were split into three groups according to treatment received: Group 1 – cisplatin-based chemotherapy and cranial radiotherapy; Group 2 - platinum-based chemotherapy, no cranial radiotherapy; Group 3 – benign brain tumours treated with surgery only. Data was collected retrospectively from patient notes. RESULTS Overall 69.5% of those treated with platinum-based chemotherapy experienced ototoxicity as assessed by Brock grading and 5.9% of patients had reduced visual acuity. Patients in Group 1 had the highest prevalence of both. 44.4% of patients in Group 1 needed increased educational support following treatment, either with extra support in the classroom or being unable to continue in mainstream school. 12.5% of Group 2 patients required such support and 31.3% in Group 3. CONCLUSIONS Children with CNS tumours frequently require support for future education but those treated with both platinum-based chemotherapy and cranial radiotherapy are at particular risk, which may be compounded by co-existent ototoxicity and visual impairment. It is essential to provide appropriate support for this patient cohort in order to maximise their educational potential.
