RESUMEN
In the frontline high-dose phase 3 FIL-MCL0208 trial (NCT02354313), 8% of enrolled mantle cell lymphoma (MCL) patients could not be randomised to receive lenalidomide (LEN) maintenance vs observation after autologous stem cell transplantation (ASCT) due to inadequate hematological recovery and 52% of those who started LEN, needed a dose reduction due to toxicity. We therefore focused on the role played by CD34 + hematopoietic stem cells (PBSC) harvesting and reinfusion on toxicity and outcome. Overall, 90% (n = 245) of enrolled patients who underwent the first leukapheresis collected ≥ 4 × 106 PBSC/kg, 2.6% (n = 7) mobilized < 4 × 106 PBSC/kg and 7.7% (n = 21) failed the collection. Similar results were obtained for the planned second leukapheresis, with only one patient failing both attempts. Median count of reinfused PBSC was 5 × 106/kg and median time to recovery from neutropenia G4 was 10 days from ASCT. No impact of mobilizing subtype or number of reinfused PBSC on hematological recovery and LEN dose reduction was noted. At a median follow-up of 75 months from ASCT, PFS and OS of transplanted patients were 50% and 73%, respectively. A long lasting G4 neutropenia after ASCT (> 10 days) was associated with a worse outcome, both in terms of PFS and OS. In conclusion, although the harvesting procedures proved feasible for younger MCL patients, long-lasting cytopenia following ASCT remains a significant issue: this can hinder the administration of effective maintenance therapies, potentially increasing the relapse rate and negatively affecting survival outcomes.

PURPOSE: To investigate whether intensive follow-up (INT) after surgery for endometrial cancer impact health-related quality of life (HRQoL) and healthcare costs compared to minimalist follow-up (MIN), in the absence of evidence supporting any benefit on 5-year overall survival. METHODS: In the TOTEM trial, HRQoL was assessed using the SF-12 and the Psychological General Well-Being (PGWB) questionnaires at baseline, after 6 and 12 months and then annually up to 5 years of follow-up. Costs were analyzed after 4 years of follow-up from a National Health Service perspective, stratified by risk level. The probability of missing data was analyzed for both endpoints. RESULTS: 1847 patients were included in the analyses. The probability of missing data was not influenced by the study arms (MIN vs INT OR: 0.97 95%CI: 0.87-1.08). Longitudinal changes in HRQoL scores did not differ between the two follow-up regimens (MIN vs INT SF-12 PCS: -0.573, CI95%: -1.31; 0.16; SF-12 MCS: -0.243, CI95%: -1.08; 0.59; PGWB: -0.057, CI95%: -0,88; 0,77). The mean cost difference between the intensive and minimalist arm was 531 for low-risk patients and 683 for high-risk patients. CONCLUSION: In the follow-up of endometrial cancer after surgery, a minimalist treatment regimen did not affect quality of life and was cost-saving in both low-risk and high-risk recurrence patients. As previous results showed no survival benefit, a minimalist approach is justified. The relevant proportion of missing data on secondary outcomes of interest could be a critical point that deserves special attention.

BACKGROUND: Multiple osteochondromas is genetic disorder characterized by the formation of multiple benign cartilage-capped bone tumors, named osteochondromas, during skeletal development. The most feared complication is the secondary peripheral chondrosarcoma, a malignant cartilaginous neoplasm that arises from the chondroid cap of pre-existent osteochondromas. We conducted a retrospective cohort study on patients diagnosed and followed up from 1960 to 2019 to describe the clinical and pathological features of individuals affected by peripheral chondrosarcoma in multiple osteochondromas, to evaluate follow up information and individual outcome and to compare the results with literature. Data, including age, gender, site, histological grade, cartilage cap thickness, surgical treatments, surgical margins, genotype mutational status as well as treatment details were captured from the hospital electronic health records and from Registry of Multiple Osteochondromas. In addition, a complete histological review of all hematoxylin and eosin (H&E)-stained sections has been performed by expert pathologists. RESULTS: One hundred five of the screened cases were included in the present study. The age at diagnosis of SPC ranges from 13 to 63, with median age at diagnosis of 34 years. The site most frequently affected by malignant degeneration was the pelvis (46 patients, 44%) with higher incidence in male patients (32 males vs.14 females). The second one was lower limbs (including femur, fibula, or tibia), identified in 35 patients. Histological information - available for 103 patients - showed: 59 patients with grade 1; 40 patients had a grade 2 and 4 patients had a grade 3. The most common surgical treatment was the complete resection, followed by debulking, amputation and partial resection. Most of cases did not have recurrence of the disease. Outcome in disease-free survival highlights that a worse course of the disease was associated with histological grade 2 or 3, and partial resection surgery. In most of analyzed cases (94%) a pathogenic variant was identified. CONCLUSIONS: In conclusion, the present study gives an overview of the secondary peripheral chondrosarcomas, confirming that this disease represents an impacting complication for multiple osteochondromas patients and suggests that malignant transformation can occur also in younger patient, in a not irrelevant number of cases.

Adults with obesity have a higher risk of hospitalization and high hospitalization-related healthcare costs. However, a predictive model for the risk of readmission in patients with severe obesity is lacking. We conducted a retrospective cohort study enrolling all patients admitted for severe obesity (BMI ≥ 40 kg/m2) between 2009 and 2018 to the Istituto Auxologico Italiano in Piancavallo. For each patient, all subsequent hospitalizations were identified from the regional database by a deterministic record-linkage procedure. A total of 1136 patients were enrolled and followed up for a median of 5.7 years (IQR: 3.1-8.2). The predictive factors associated with hospital readmission were age (HR = 1.02, 95%CI: 1.01-1.03, p < 0.001), BMI (HR = 1.02, 95%CI: 1.01-1.03, p = 0.001), smoking habit (HR = 1.17, 95%CI: 0.99-1.38, p = 0.060), serum creatinine (HR = 1.22, 95%CI: 1.04-1.44, p = 0.016), diabetes (HR = 1.17, 95%CI: 1.00-1.36, p = 0.045), and number of admissions in the previous two years (HR = 1.15, 95%CI: 1.07-1.23, p < 0.001). BMI lost its predictive role when restricting the analysis to readmissions within 90 days. BMI and diabetes lost their predictive roles when further restricting the analysis to readmissions within 30 days. In conclusion, in this study, we identified predictive variables associated with early and long-term hospital readmission in patients with severe obesity. Whether addressing modifiable risk factors could improve the outcome remains to be established.

Currently, treatment allocation of patients with Mantle Cell Lymphoma (MCL) is mainly based on age and medical fitness. The combined MCL International Prognostic Index (MIPI-c) allows to predict prognosis using clinical factors (MIPI) and the Ki-67 index. However, high p53 expression as surrogate for TP53 alterations has demonstrated to be an independent predictor for poor outcome. We aimed to define a clear high-risk group based on the combination of MIPI, Ki-67 and p53 expression/TP53 alteration. A total of 684 patients from the prospective European MCL-Younger and MCL-Elderly trials were evaluable. The classification of high-risk disease (HRD) as high-risk MIPI-c or p53 expression >50% versus low-risk disease (LRD) as low, low-intermediate or high-intermediate MIPI-c and p53 expression ≤50% allowed to characterize two distinct groups with highly divergent outcome. Patients with HRD had significantly shorter median failure-free survival (FFS) (1.1 vs. 5.6 years, p < 0.0001) and overall survival (OS) (2.2 vs. 13.2 years, p < 0.0001) compared to those with LRD. These major differences were confirmed in two validation cohorts from the Italian MCL0208 and the Nordic-MCL4 trials. The results suggest that this subset of HRD patients is not sufficiently managed with the current standard treatment and is asking for novel treatment strategies.

BACKGROUND: Early hospital discharge planning can help to reduce the length of stay and unplanned readmission in high-risk patients. Therefore, it is important to select patients who can benefit from a personalized discharge planning based on validated tools. The modified Blaylock Risk Assessment Screening Score (BRASS) is routinely used in the Molinette Hospital (Turin, Italy) to screen patients at high risk for discharge, but the effectiveness of the discharge planning is uncertain in intermediate-risk patients. OBJECTIVE: To evaluate the best strategy for discharge planning by the Continuity of Care Hospital Unit (CCHU) in intermediate-risk patients according to modified BRASS. DESIGN: Cluster-randomized, multiple crossover trial. PARTICIPANTS: Adult patients admitted in the Medicine and Neurology departments of the Molinette Hospital in Turin, Italy, between June 2018 and May 2019 with a BRASS intermediate risk. INTERVENTIONS: A routine discharge planning strategy (RDP, Routine Discharge Plan), which involved the management of all intermediate-risk patients, was compared to an on-demand discharge planning strategy (DDP, on-Demand Discharge Planning), which involved only selected patients referred to the CCHU by ward staff. MAIN MEASURES: The primary outcome was the 90-day hospital readmission for any cause (HR90). Secondary outcomes included the prolonged length of stay (pLOS). KEY RESULTS: Eight hundred two patients (median age 79 years) were included (414 RDP and 388 DDP). Comparing RDP vs. DDP periods, HR90 was 27.6% and 27.3% (OR 1.01, 90%CI 0.76-1.33, p = 0.485); and pLOS was 47 (11.4%) and 40 (10.3%) (OR 1.24, 95%CI 0.72-2.13, p = 0.447), respectively. CONCLUSIONS: This is one of the largest randomized study conducted to compare the effectiveness of two different hospital discharge planning strategies. In patients with intermediate risk of hospital discharge, a RDP offers no advantage over a DDP and results in an unnecessary increase in staff workload. TRIAL REGISTRATION: Clinicaltrials.gov: NCT03436940.

The combination of rituximab, bendamustine, and low-dose cytarabine (R-BAC) has been studied in a phase 2 prospective multicenter study from Fondazione Italiana Linfomi (RBAC500). In 57 previously untreated elderly patients with mantle cell lymphoma (MCL), R-BAC was associated with a complete remission rate of 91% and 2-year progression-free survival (PFS) of 81% (95% confidence interval [CI], 68-89). Here, we report the long-term survival outcomes, late toxicities, and results of minimal residual disease (MRD) evaluation. After a median follow-up of 86 months (range, 57-107 months), the median overall survival (OS) and PFS were not reached. The 7-year PFS and OS rates were 55% (95% CI, 41-67), and 63% (95% CI, 49-74), respectively. Patients who responded (n = 53) had a 7-year PFS of 59% (95% CI, 44-71), with no relapse or progression registered after the sixth year. In the multivariate analysis, blastoid/pleomorphic morphology was the strongest adverse predictive factor for PFS (P = .04). Patients with an end of treatment negative MRD had better, but not significant, outcomes for both PFS and OS than patients with MRD-positive (P = 0.148 and P = 0.162, respectively). There was no signal of late toxicity or an increase in secondary malignancies during the prolonged follow-up. In conclusion, R-BAC, which was not followed by maintenance therapy, showed sustained efficacy over time in older patients with MCL. Survival outcomes compare favorably with those of other immunochemotherapy regimens (with or without maintenance), including combinations of BTK inhibitors upfront. This study was registered with EudraCT as 2011-005739-23 and at www.clinicaltrials.gov as #NCT01662050.

OBJECTIVES: Chemotherapy-induced neutropenia in acute myeloid leukaemia (AML) is a risk factor for life-threatening infections. Early diagnosis and prompt interventions are associated with better outcomes, but the prediction of infection severity remains an open question. Recently, National Early Warning Score (NEWS) and quick sequential organ failure assessment (qSOFA) scores were proposed as warning clinical instruments predicting in-hospital mortality, but their role in the haematological context is still unknown. METHODS: We retrospectively assess the predictive role of NEWS and qSOFA in a large and homogeneous cohort of adult AML patients treated with intensive chemotherapy. In a total of 1048 neutropenic episodes recorded in 334 consecutive patients, the scores were applied to predict outcomes on the same day of fever onset, and after 24 and 48 h from score calculation. RESULTS: Both NEWS and qSOFA significantly predicted death, with more accuracy on the same day (NEWS AUROC 0.984 and qSOFA AUROC 0.969) and after 24 h (NEWS AUROC 0.928 and qSOFA AUROC 0.887), while remained moderately accurate after 48 h. Furthermore, also ICU admission was accurately predicted at fever onset and after 24 h. CONCLUSIONS: Both scores were useful tools in the management of post chemotherapy neutropenic febrile AML patients.

The standard treatment for young patients with untreated PTCLs is based on anthracycline containing-regimens followed by high-dose-chemotherapy and stem-cell-transplantation (HDT + SCT), but only 40% of them can be cured. Romidepsin, a histone-deacetylase inhibitor, showed promising activity in relapsed PTCLs; in first line, Romidepsin was added with CHOP. We designed a study combining romidepsin and CHOEP as induction before HDT + auto-SCT in untreated PTCLs (PTCL-NOS, AITL/THF, ALK-ALCL), aged 18-65 years. A phase Ib/II trial was conducted to define the maximum tolerated dose (MTD) of Ro-CHOEP, and to assess efficacy and safety of 6 Ro-CHOEP as induction before HDT. The study hypothesis was to achieve a 18-month PFS of 70%. Twenty-one patients were enrolled into phase Ib; 7 dose-limiting toxicities were observed, that led to define the MTD at 14 mg/ms. Eighty-six patients were included in the phase II. At a median follow-up of 28 months, the 18-month PFS was 46.2% (95%CI:35.0-56.7), and the 18-month overall survival was 73.1% (95%CI:61.6-81.7). The overall response after induction was 71%, with 62% CRs. No unexpected toxicities were reported. The primary endpoint was not met; therefore, the enrollment was stopped at a planned interim analysis. The addition of romidepsin to CHOEP did not improve the PFS of untreated PTCL patients.

An underdosing of collagenase clostridium histolyticum (0.32 mg) is proposed as a potentially effective option in patients with additional cords in the same hand, after the first cord has been treated with the regular dose of 0.58 mg. The aim of this study was to analyze whether this additional dose is tolerated and effective. Methods: Patients with Dupuytren's disease affecting MCP joints with at least two independent pathological cords, causing deformity of two digits, were considered, with their written informed consent, for a simultaneous injection of the two cords with a single vial of collagenase. Digits treated with the standard dose of 0.58 mg were compared with digits injected with the smaller dose of 0.32 mg. Passive extension deficit and range of motion were evaluated after injection. Complications were also compared. Results: A total of 26 patients (29 hands) were included in the study. Of these, nine patients had two independent cords within one hand, and 17 patients had a single cord (three of these with a cord in each hand). Thirty-five digits were injected, 23 with 0.58 mg and 12 with 0.32 mg. Apart from a smaller mean percentage variation in passive extension deficit within 24 hours in the 0.58-mg dose compared with 0.32 mg (29% versus 40%, P = 0.031), no other differences emerged if a dose of 0.32 mg is used instead of 0.58 mg, in terms of selected outcome measures and rate of complications (P > 0.05). Conclusion: Underdosing collagenase clostridium histolyticum is equally effective in the treatment of Dupuytren's disease.
RESUMEN
Donor selection may contribute to improve clinical outcomes of T cell-replete haploidentical stem cell transplantation (Haplo-SCT) with post-transplant cyclophosphamide (PT-Cy). Impact of second-degree related donor (SRD) was not fully elucidated in this platform. We retrospectively compared the outcome of patients receiving Haplo-SCT either from a SRD (n = 31) or a first-degree related donor (FRD, n = 957). Median time to neutrophil and platelet recovery did not differ between a SRD and a FRD transplant (p = 0.599 and 0.587). Cumulative incidence of grade II-IV acute graft-versus host disease (GVHD) and moderate-severe chronic GVHD was 13% and 19% after SRD vs 24% (p = 0.126) and 13% (p = 0.395) after FRD transplant. One-year cumulative incidence of non-relapse mortality (NRM) was 19% for SRD and 20% for FRD (p = 0.435) cohort. The 3-year probability of overall survival (OS) and progression-free survival (PFS) was 42% vs 55% (p = 0.273) and 49% vs 35% (p = 0.280) after SRD and FRD transplant, respectively. After propensity score adjustment or matched pair analysis, the outcome of patients receiving Haplo-SCT from a SRD or a FRD did not differ in terms of NRM, OS, PFS, acute and chronic GVHD. Our results suggest that a SRD is a viable option for Haplo-SCT with PT-Cy when a FRD is not available.

BACKGROUND: The aim of the study was to examine the relationship among patients' characteristics, intraoperative pathology and pre/post-operative symptoms in a cohort of patients undergoing arthroscopic partial meniscectomy for symptomatic meniscal tears. METHODS: Clinical data were collected (age, sex, body mass index, time to surgery, trauma). Intraoperative cartilage pathology was assessed with Outerbridge score. Meniscal tears were graded with the ISAKOS classification. Synovial inflammation was scored using the Macro-score. Patient symptoms were assessed pre/post-operatively using the KOOS instrument. RESULTS: In the series of 109 patients (median age 47 years), 50% of the meniscal tears were traumatic; 85% of patients showed mild to moderate synovitis; 52 (47.7%) patients had multiple cartilage defects and 31 (28.4%) exhibited a single focal chondral lesion. Outerbridge scores significantly correlated with patient age, BMI and synovial inflammation. There was a correlation between severity of chondral pathology and high-grade synovial hyperplasia. Pre-operative KOOS correlated with BMI, meniscal degenerative changes and symptom duration. Obesity, time to surgery, presence of high-grade synovial hyperplasia and high-grade cartilage lesions were independent predictors of worse post-operative pain and function. CONCLUSION: We demonstrated that pre-operative symptoms and post-operative outcomes correlate with synovitis severity and cartilage pathology, particularly in old and obese patients that underwent arthroscopic partial meniscectomy. Importantly, patients with a degenerative meniscal pattern and with longer time to surgery experienced more severe cartilage damage and, consequentially, pain and dysfunction. These findings are fundamental to identify patients suitable for earlier interventions.
RESUMEN
(1) Background: The Pediatric Outcomes Data Collection Instrument (PODCI) is an English-language questionnaire specifically designed to assess health-related quality of life in children and adolescents with musculoskeletal disorders. This scoring system has been translated into several languages. Given the lack of an Italian version of the PODCI, this study aimed to translate, cross-culturally adapt, and assess the psychometric properties of the PODCI score in the Italian pediatric population. (2) Methods: The PODCI questionnaire was culturally adapted to Italian patients in accordance with the literature guidelines. The study included 59 participants from a single orthopedic institution who underwent orthopedic surgery for various skeletal conditions. The questionnaire was administered to participants at multiple time-points (T0, T1, T2). Internal consistency was evaluated using Cronbach's alpha. Reproducibility was assessed using the intraclass correlation coefficient (ICC) between T0 and T1 assessment. Criterion validity was assessed using Spearman's correlation coefficients between PODCI and the Hospital for Special Surgery Pediatric Functional Activity Brief Scale (HSS Pedi-FABS). Responsiveness was evaluated by the difference between T0 and T2 using the effect size (ES) and the standardized response mean (SRM) calculation. (3) Results: Cronbach's alpha was acceptable in both the self- and parent-reported versions with values of 0.78 (0.68-0.90) and 0.84 (0.60-0.92), respectively. The ICC fluctuated between 0.31 and 0.89 for self-reported and 0.49 to 0.87 for pediatrics. The Spearman's r showed a moderate correlation between HSS Pedi-FABS and the "Sport & Physical Functioning" and "Global Functioning" domains. ES and SRM varied from small to moderate across all the domains. (4) Conclusions: This study demonstrates that the Italian version of the PODCI, translated following the international standardized guidelines, is reliable, valid, and responsive in pediatric patients who underwent orthopedic surgery.
RESUMEN
Minimal residual disease (MRD) analysis is a known predictive tool in mantle cell lymphoma (MCL). We describe MRD results from the Fondazione Italiana Linfomi phase 3 MCL0208 prospective clinical trial assessing lenalidomide (LEN) maintenance vs observation after autologous stem cell transplantation (ASCT) in the first prospective comprehensive analysis of different techniques, molecular markers, and tissues (peripheral blood [PB] and bone marrow [BM]), taken at well-defined time points. Among the 300 patients enrolled, a molecular marker was identified in 250 (83%), allowing us to analyze 234 patients and 4351 analytical findings from 10 time points. ASCT induced high rates of molecular remission (91% in PB and 83% in BM, by quantitative real-time polymerase chain reaction [RQ-PCR]). Nevertheless, the number of patients with persistent clinical and molecular remission decreased over time in both arms (up to 30% after 36 months). MRD predicted early progression and long-term outcome, particularly from 6 months after ASCT (6-month time to progression [TTP] hazard ratio [HR], 3.83; P < .001). In single-timepoint analysis, BM outperformed PB, and RQ-PCR was more reliable, while nested PCR appeared applicable to a larger number of patients (234 vs 176). To improve MRD performance, we developed a time-varying kinetic model based on regularly updated MRD results and the MIPI (Mantle Cell Lymphoma International Prognostic Index), showing an area under the ROC (Receiver Operating Characteristic) curve (AUROC) of up to 0.87 using BM. Most notably, PB reached an AUROC of up to 0.81; with kinetic analysis, it was comparable to BM in performance. MRD is a powerful predictor over the entire natural history of MCL and is suitable for models with a continuous adaptation of patient risk. The study can be found in EudraCT N. 2009-012807-25 (https://eudract.ema.europa.eu/).

Salvage immunochemotherapy and transplant consolidation is the standard treatment for relapsed or refractory (R/R) diffuse large B-cell lymphoma (DLBCL). We tested a combination of Obinutuzumab and DHAP for treating R/R DLBCL. The primary end point was the rate of complete metabolic response (CMR). Secondary end points were stem cell mobilization, stem cell engraftment, overall survival, and feasibility. In this prospective, phase-2, single-arm trial (EudraCT 2014-004014-17) patients received the standard three doses of Obinutuzumab for the first cycle, and then one dose. Patients with CMR were consolidated with an autologous stem cell transplantation (ASCT). An interim analysis was provided after the first 29 patients to confirm the initial null hypothesis that at least 10/29 patients would achieve CMR. Among the 29 patients evaluated for the first stage only six patients (6/29, 21%) achieved CMR, thus, study enrollment was stopped. Nine patients exhibited extra-hematologic toxicities ≥ grade 3. Among the 19 patients that started stem cell mobilization, one failed (5%) and 18 achieved mobilization (95%). Of these 18 patients, nine were reinfused. Mobilization was observed in 16 patients (89%) after one or two apheresis rounds. The mean number of CD34 + cells mobilized was 5.8 × 106 /Kg (median: 5.5, IQR: 5-6.75). The mean number of reinfused CD34 + cells in the nine patients was 4.1 × 106 /Kg (median: 4.1, IQR: 3.5-5). Obinutuzumab combined with DHAP did not compromise stem cell mobilization or engraftment after ASCT in patients with DLBCL. However, Obinutuzumab + DHAP provided a lower CMR rate than expected.

BACKGROUND: Secondary peripheral chondrosarcomas arising in solitary osteochondromas is an unusual complication, reported in small series. In this study, we aimed to present our experience with this rare variant of chondrosarcoma and compare results with already published data in order to determine prognostic factors for overall and disease-free survival. METHODS: The case study includes retrospective data from patients diagnosed at a single institution from 1943 to 2019. Clinical data were collected reviewing all available medical records from first to last follow-up visits. To exclude the presence of the Multiple Osteochondroma Hereditary Syndrome, few patients, with a suspect of a familial form of the disease, were evaluated for the presence of germline heterozygous variants in EXT1 and EXT2 genes. Results were summarized using descriptive statistics and statistical analysis were performed to reveal associations between variables. RESULTS: Two hundred and fourteen secondary peripheral chondrosarcomas that arose exclusively from solitary osteochondromas diagnosed in a multidisciplinary setting at the IRCCS Istituto Ortopedico Rizzoli were retrospectively identified, 66.4% males and 33.6% females with a median age at diagnosis of 38 years. The local recurrence rate was 17.3%, while the metastases one was 5.1%. Besides age, a high histologic grade is the only factor associated with worse 5-year and 10-year overall survival (log-rank p = 0.0005, HR = 3.74; 95% CI 1.69-8.26). Moreover, high histological grade (HR = 3.75; 95% CI = 1.69-8.34; p = 0.001) and surgical debulking (HR = 3.71; 95% CI = 1.57-8.79; p = 0.003) were associated with a significantly worse disease-free survival. CONCLUSIONS: Our study confirm the low-grade behavior of secondary peripheral chondrosarcomas and demonstrate that the best choice of treatment for those arising in solitary osteochondromas is the wide surgical excision, when possible. Location per se is not a factor that affects prognosis, while the accurate histological grade assessment is correlated with the tumor aggressiveness and a long term follow up is necessary for this rare variant of chondrosarcoma.

BACKGROUND: There is need for improvement in effective pressure ulcers preventive strategies. OBJECTIVE: To study whether a multi-layer silicone-adhesive polyurethane foam dressing shaped for the sacrum prevents PUs development in addition to standard PU preventive care for at-risk hospitalized patients. DESIGN: Open-label, parallel group, multi-center randomized controlled trial. PARTICIPANTS AND SETTING: 709 in-hospital patients at risk for pressure ulcers from 25 medical, surgical, and intensive care units of 12 Italian hospitals. METHODS: A multi-layer silicone-adhesive polyurethane foam was applied to the sacrum in addition to standard PUs preventive care in the intervention group. In the control group, standard preventive care alone, including systematic pressure ulcer risk assessment, skin assessment three times per day, routine positioning every 4 h, use of active support surface as appropriate, and incontinence skin care, was guaranteed. Primary outcome was incidence of sacral pressure ulcers of any stage at seven days from hospital admission. Secondary outcomes were incidence of sacral pressure ulcers ≥ II stage, number of days needed to PU development, number of skin adverse events due to the foam dressing, number of dressings used for each patient, number of withdrawing patients due to discomfort caused by the foam dressing. Participants were evaluated at baseline and at seven days. RESULTS: In patients admitted to medical units, 15/113 controls and 4/118 in the intervention group developed sacral pressure ulcers (p = 0.010; absolute reduction 9.2%; NNT for benefit 11, 95% CI 6 to 44). In patients admitted to surgical units, 21/144 controls and 8/142 in the intervention group developed sacral pressure ulcers (p = 0.010; absolute reduction 8.9%; NNT for benefit 11 95% CI 6 to 49). Pressure ulcers incidence was not significantly different between the randomization arms (5.2% experimental vs 10.4% control, p = 0.141) in patients admitted to intensive care units. Overall, 46/358 (12.8%) controls and 17/351 (4.8%) in the intervention group developed sacral pressure ulcers (p<0.001; absolute reduction 8%; number needed to treat (NNT) for benefit 12, 95% CI 8 to 26). Incidence of sacral pressure ulcers ≥ II stage did not differ significantly between the two groups. No adverse skin reactions and discomfort attributable to the foam application were reported. CONCLUSION: A sacral multi-layer silicone-adhesive polyurethane foam in addition to standard preventive care is effective for pressure ulcers prevention in at-risk hospitalized patients admitted to medical and surgical units. TRIAL REGISTRATION: ClinicalTrials.gov NCT03900455. The registration (April 1st, 2019) occurred before the first patient was enrolled (October 21st, 2019).

BACKGROUND: Bone tumors are not a frequent occurrence and bone infarct-associated sarcomas are even rarer. The prognosis of patients experiencing this disease is poor and treatment for them remains a challenge. Nevertheless, hardly any analyses in literature report on secondary osteosarcoma (SO) on bone infarct and most of the data available do not provide sufficient details. We evaluated whether this condition could be further characterized and if prognosis could be influenced by the chemotherapy (ChT) treatment. We sought to determine: (1) the main features of this rare disease; (2) the overall survival (OS) rate; (3) the OS rate associated to ChT treatment; and (4) the correspondence between our results and published data in terms of survival. METHODS: We retrospectively reviewed patients admitted at the Rizzoli Orthopedic Institute of Bologna between 1992 and 2018 (1,465 total cases of osteosarcoma). We identified a list of 11 cases of SO on bone infarct (cohort 1). We conferred about the epidemiology, surgical and ChT treatment, and surveillance of infarct-associated osteosarcoma showing the correlation to data present in literature, corresponding to 14 case reports published within 1962-2018 (cohort 2). RESULTS: (1) Cohort 1 was made of 11 patients: six females and five males, median age was 55 years. Nine (81%) were grade 4 and two (19%) were grade 3. Tumor predominantly arose on distal femur (64%). Most of patients had localized osteosarcoma at the diagnosis (81%); resection surgery was the elective treatment (73%) followed by amputation (18%). Of 11 patients, seven received also ChT (64%). (2) Five-year OS was 62% (95% confidence interval [CI]: 28-84). Median OS was 74 months (95% CI: 12-not reached). The cumulative incidence of cancer-related deaths (CICRD) was 37.7% (95% CI: 11.4-64.5) at 120 months. (3) In the group treated with only surgery, OS was 50% at 5 years. For patients treated with any form of ChT, OS was 71% at 5 years (p = 0.4773) and hazard ratio (HR) 0.56. The CICRD was 29% (at 2 years of follow-up. Instead, it was of 50% for patients treated only with surgery. (4) Median survival was 74 months and 12 months for cohort 1 and cohort 2, respectively (p = 0.0247). Data analysis showed a decreased HR for cohort 1 compared to cohort 2 (HR 0.315). Results confirmed also stratifying for age and ChT administration (HR 0.333). CONCLUSIONS: Based on this work, our opinion is that the treatment of SO patients with ChT combined to surgery improves patients' survival.
