RESUMO

BACKGROUND: Management of lymphoid malignancies requires substantial health system resources. Total national health expenditure might influence population-based lymphoid malignancy survival. We studied the long-term survival of patients with 12 lymphoid malignancy types and examined whether different levels of national health expenditure might explain differences in lymphoid malignancy prognosis between European countries and regions. METHODS: For this observational, retrospective, population-based study, we analysed the EUROCARE-6 dataset of patients aged 15 or older diagnosed between 2001 and 2013 with one of 12 lymphoid malignancies defined according to International Classification of Disease for Oncology (third edition) and WHO classification, and followed up to 2014 (Jan 1, 2001-Dec 31, 2014). Countries were classified according to their mean total national health expenditure quartile in 2001-13. For each lymphoid malignancy, 5-year and 10-year age-standardised relative survival (ASRS) was calculated using the period approach. Generalised linear models indicated the effects of age at diagnosis, gender, and total national health expenditure on the relative excess risk of death (RER). FINDINGS: 82 cancer registries (61 regional and 21 national) from 27 European countries provided data eligible for 10-year survival estimates comprising 890 730 lymphoid malignancy cases diagnosed in 2001-13. Median follow-up time was 13 years (IQR 13-14). Of the 12 lymphoid malignancies, the 10-year ASRS in Europe was highest for hairy cell leukaemia (82·6% [95% CI 78·9-86·5) and Hodgkin lymphoma (79·3% [78·6-79·9]) and lowest for plasma cell neoplasms (29·5% [28·9-30·0]). RER increased with age at diagnosis, particularly from 55-64 years to 75 years or older, for all lymphoid malignancies. Women had higher ASRS than men for all lymphoid malignancies, except for precursor B, T, or natural killer cell, or not-otherwise specified lymphoblastic lymphoma or leukaemia. 10-year ASRS for each lymphoid malignancy was higher (and the RER lower) in countries in the highest national health expenditure quartile than in countries in the lowest quartile, with a decreasing pattern through quartiles for many lymphoid malignancies. 10-year ASRS for non-Hodgkin lymphoma, the most representative class for lymphoid malignancies based on the number of incident cases, was 59·3% (95% CI 58·7-60·0) in the first quartile, 57·6% (55·2-58·7) in the second quartile, 55·4% (54·3-56·5) in the third quartile, and 44·7% (43·6-45·8) in the fourth quartile; with reference to the European mean, the RER was 0·80 (95% CI 0·79-0·82) in the first, 0·91 (0·90-0·93) in the second, 0·94 (0·92-0·96) in the third, and 1·45 (1·42-1·48) in the fourth quartiles. INTERPRETATION: Total national health expenditure is associated with geographical inequalities in lymphoid malignancy prognosis. Policy decisions on allocating economic resources and implementing evidence-based models of care are needed to reduce these differences.

RESUMO

Our aim was to analyse, on a population level, the year-long decline in cancer diagnoses in the region of Lombardy (Italy), and to characterise the tumours with the greatest reduction in diagnosis by patient age, sex and tumour stage at diagnosis. We used the health care utilisation databases of the Lombardy region to identify cancer patients' characteristics (eg, sex, age) and cancer-related information (eg, cancer site, stage at diagnosis). The frequency of new cancer diagnoses in 2019 and 2020 were compared in terms of percentage differences in undiagnosed cases. We observed two peaks in the decline in cancer diagnoses: March to May 2020 (-37%) and October to December 2020 (-19%). The decline persisted over the course of 2020 and was higher in males and patients aged 74+. Diagnoses of all four common cancers analysed (female breast, lung, colorectal and prostate) remained below pre-pandemic levels. For breast and colorectal cancers, the decline in diagnoses was high in the age groups targeted by population-based screening programmes. We observed a reduction in localised stage cancer diagnoses for all four cancers. Our data confirm that timely monitoring of cancer diagnoses and interventions to prevent disruption of routine diagnostic services are needed to mitigate the impact of emergencies on cancer patients.

RESUMO

BACKGROUND: Evidence about late effects in adolescent and young adult (AYA) cancer survivors is scarce. This study assessed the risk of subsequent malignant neoplasms (SMNs) to identify the most common SMNs to be considered in follow-up care. METHODS: Population-based cancer registries retrospectively identified first primary tumors (between 1976 and 2013) and SMNs in AYAs (15-39 years old at their cancer diagnosis). AYA cancer survivors were those alive at least 5 years after their first cancer diagnosis. The excess risk of SMNs was measured as standardized incidence ratios (SIRs) and absolute excess risk together with the cumulative incidence of SMNs. RESULTS: The cohort included 67,692 AYA cancer survivors. The excess risk of developing any SMN (SIR, 1.6; 95% confidence interval, 1.5-1.7) was 60%. The excess risk of SMNs was significantly high for survivors of lymphomas; cancers of the breast, thyroid, female genital tract, digestive organs, gonads, and urinary tract; and melanomas. The cumulative incidence of all SMNs in AYA cancer survivors within 25 years of their first cancer diagnosis was approximately 10%. Subsequent tumors contributing to approximately 60% of all SMNs were breast cancer, colorectal cancer, corpus uteri cancer, and ovarian cancer in females and colorectal cancer, bladder cancer, prostate cancer, lung cancer, and lymphomas in males. CONCLUSIONS: These results highlight the need to personalize follow-up strategies for AYA cancer survivors.

RESUMO

BACKGROUND: Data on late mortality from pediatric germ cell tumors (GCTs) are limited to small case series. Our population-based study aimed to investigate excess risk of death in survivors of GCT in childhood and adolescence, whether long-term mortality changed over time and by period of diagnosis. METHODS: The PanCare Childhood and Adolescent Cancer Survivor Care and Follow-Up Studies (PanCareSurFup) cohort includes 2773 five-year survivors diagnosed under 21 years of age with gonadal and extragonadal GCT (from 1940 to 2008). We calculated standardized mortality ratios (SMRs) and absolute excess risks (AERs). We fitted a Cox's model to assess the impact of treatment period. We estimated 10-year survival and calculated average percentage changes between periods of diagnosis (1970-1979, 1980-1989, 1990-1999) to assess whether late mortality decreased. RESULTS: GCT survivors had an almost four-fold excess risk of dying compared to general population. The risk of death for patients treated after 1980 was nearly halved compared to patients treated before 1980. Survivors diagnosed in 1990-1999 had a 10-year survival rate of 99%, which was 2.4% and 1.1% higher than for patients treated in 1970-1979 and 1980-1989, respectively. CONCLUSIONS: This is the largest population-based study in Europe and showed a decrease in long-term mortality for survivors of GCTs in childhood and adolescence over the last decades. After the introduction of platinum compound in 1980, which is a paradigm of success compared to the previous treatments, no major changes in drug therapies have been made to treat GCTs in the last 40 years. However, GCT survivors maintain an excessive risk of death that requires long-term care.

RESUMO

Improvements during 1978 to 2006 in the 5-year survival rate of adolescents and young adults (AYAs, age 15-39) and children with cancers common to both age groups were evaluated for 1978 to 2006 in Europe and the USA. AYAs had absolute survival increases of 25% and 15% in Europe and the USA, respectively, but in both cases, AYA 5-year survival was, as of 2006, 4% lower than those in children. Acute lymphoblastic leukemia (ALL) explained most of the survival difference between AYAs and children on both the continents. In the USA, 20- to 39-year-olds with ALL have had less survival improvement than those in Europe.

RESUMO

The increasing incidence of infections caused by drug-resistant pathogens requires new efforts for the discovery of novel antibiotics. By screening microbial extracts in an assay aimed at identifying compounds interfering with cell wall biosynthesis, based on differential activity against a Staphylococcus aureus strain and its isogenic l-form, the potent enduracyclinones (1, 2), containing the uncommon amino acid enduracididine linked to a six-ring aromatic skeleton, were discovered from different Nonomuraea strains. The structures of 1 and 2 were established through a combination of derivatizations, oxidative cleavages, and NMR analyses of natural and 13C-15N-labeled compounds. Analysis of the biosynthetic cluster provides the combination of genes for the synthesis of enduracididine and type II polyketide synthases. Enduracyclinones are active against Gram-positive pathogens (especially Staphylococcus spp.), including multi-drug-resistant strains, with minimal inhibitory concentrations in the range of 0.0005 to 4 µg mL-1 and with limited toxicity toward eukaryotic cells. The combined results from assays and macromolecular syntheses suggest a possible dual mechanism of action in which both peptidoglycan and DNA syntheses are inhibited by these molecules.

RESUMO

PURPOSE: The choice of the cast length in conservative management of distal radius fractures still represents a debated controversy. Historically, the elbow is immobilized to reduce the risk of secondary displacement; however, short-arm casts are currently felt to be equally effective with less complications and better patient comfort. This paper investigates whether immobilization of the elbow is actually effective in reducing the risk of loss of reduction in conservatively manipulated distal radius fractures. METHODS: We retrospectively studied 297 consecutive patients with distal radius fractures requiring manipulation and subsequently immobilized with above-elbow cast or below-elbow cast. Maintenance of reduction, radial height, radial inclination, and volar tilt were assessed after the reduction and at 35 days. Appropriate statistical analysis was performed to correct data selection bias and to assess any difference in the effectiveness among the two treatments. RESULTS: The mean difference of loss of radial height, inclination, and volar tilt between the two groups was 0.8 mm, 0.4°, and 0.9° respectively, being not statistically significant. Average difference in reduction maintenance probability between the two groups stratified with a statistical propensity score was 1.2%. CONCLUSIONS: Above- and below-elbow casts had comparable performance in maintaining reduction of manipulated distal radius fractures.

RESUMO

Four metabolites, designated paramagnetoquinone A, B, C, and D (1-4), were isolated from three strains belonging to the actinomycete genus Actinoallomurus. Compounds 1 and 2 showed potent antibacterial activity with MIC values lower than 0.015 µg/mL against Gram-positive pathogens, including antibiotic-resistant strains. Since compounds 1 and 2 were NMR-silent due to the presence of an oxygen radical, structure elucidation was achieved through a combination of derivatizations, oxidations, and analysis of 13C-labeled compounds. The paramagnetoquinones share the same carbon scaffold as tetracenomycin but carry two quinones and a five-membered lactone fused to the aromatic system. Compounds 2 and 1 are identical except for an unprecedented replacement of a methoxy in 2 by a methylamino group in 1. Related compounds devoid of methyl group(s) and of antibacterial activity were isolated from a different Actinoallomurus strain. The likely pmq biosynthetic gene cluster was identified from strain ID145113. While the cluster encodes many of the expected enzymes involved in the formation of aromatic polyketides, it also encodes a dedicated ketoacid dehydrogenase complex and an unusual acyl carrier protein transacylase, suggesting that an unusual starter unit might prime the polyketide synthase.

RESUMO

BACKGROUND: We used the comprehensive definition of AYA (age 15 to 39 years) to update 5-year relative survival (RS) estimates for AYAs in Europe and across countries and to evaluate improvements in survival over time. METHODS: We used data from EUROCARE-6. We analysed 700,000 AYAs with cancer diagnosed in 2000-2013 (follow-up to 2014). We focused the analyses on the 12 most common cancers in AYA. We used period analysis to estimate 5-year RS in Europe and 5-year RS differences in 29 countries (2010-2014 period estimate) and over time (2004-06 vs. 2010-14 period estimates). FINDINGS: 5-year RS for all AYA tumours was 84%, ranging from 70% to 90% for most of the 12 tumours analysed. The exceptions were acute lymphoblastic leukaemia, acute myeloid leukaemia, and central nervous system tumours, presenting survival of 59%, 61%, and 62%, respectively. Differences in survival were observed among European countries for all cancers, except thyroid cancers and ovarian germ-cell tumours. Survival improved over time for most cancers in the 15- to 39-year-old age group, but for fewer cancers in adolescents and 20- to 29-year-olds. INTERPRETATION: This is the most comprehensive study to report the survival of 12 cancers in AYAs in 29 European countries. We showed variability in survival among countries most likely due to differences in stage at diagnosis, access to treatment, and lack of referral to expert centres. Survival has improved especially for haematological cancers. Further efforts are needed to improve survival for other cancers as well, especially in adolescents.

RESUMO

BACKGROUND: A strong relationship has been observed between comorbidities and the risk of severe/fatal COVID-19 manifestations, but no score is available to evaluate their association in cancer patients. To make up for this lacuna, we aimed to develop a comorbidity score for cancer patients, based on the Lombardy Region healthcare databases. METHODS: We used hospital discharge records to identify patients with a new diagnosis of solid cancer between February and December 2019; 61 comorbidities were retrieved within 2 years before cancer diagnosis. This cohort was split into training and validation sets. In the training set, we used a LASSO-logistic model to identify comorbidities associated with the risk of developing a severe/fatal form of COVID-19 during the first pandemic wave (March-May 2020). We used a logistic model to estimate comorbidity score weights and then we divided the score into five classes (<=-1, 0, 1, 2-4, >=5). In the validation set, we assessed score performance by areas under the receiver operating characteristic curve (AUC) and calibration plots. We repeated the process on second pandemic wave (October-December 2020) data. RESULTS: We identified 55,425 patients with an incident solid cancer. We selected 21 comorbidities as independent predictors. The first four score classes showed similar probability of experiencing the outcome (0.2% to 0.5%), while the last showed a probability equal to 5.8%. The score performed well in both the first and second pandemic waves: AUC 0.85 and 0.82, respectively. Our results were robust for major cancer sites too (i.e., colorectal, lung, female breast, and prostate). CONCLUSIONS: We developed a high performance comorbidity score for cancer patients and COVID-19. Being based on administrative databases, this score will be useful for adjusting for comorbidity confounding in epidemiological studies on COVID-19 and cancer impact.

RESUMO

BACKGROUND: To estimate risk of recurrence for women diagnosed with nonmetastatic breast cancer considering the risks of other causes mortality. METHODS: We extend a method based on the diagnosis-metastasis-death pathway to include risks of other causes mortality. We estimate three probabilities as cumulative incidence of: (i) being alive and recurrence-free, (ii) death for other causes before a recurrence, and (iii) recurrence. We apply the method to female breast cancer relative survival from the Surveillance, Epidemiology, and End Results Program registries (2000-2018) data. RESULTS: The cumulative incidence of recurrence shows a higher increase with more advanced cancer stage and is less influenced by age at diagnosis. At 5 years from diagnosis, the cumulative incidence of recurrence is less than 3% for those diagnosed with stage I, 10% to 13% for those diagnosed with stage II, and 37% to 47% for those diagnosed with stage III breast cancer. The estimates of recurrence considering versus ignoring the risks of dying from other causes were generally consistent, except for older women with more advanced stage, and longer time since diagnosis. In these groups, the net probability of recurrence, excluding the risks of dying from other causes, were overestimated. CONCLUSIONS: For patients with cancer who are older or long-term survivors, it is important to include the risks of other cause mortality as the crude cumulative incidence of recurrence is a more appropriate measure. IMPACT: These estimates are important in clinical decision making, as higher competing mortality may preclude the benefits of aggressive treatments.

RESUMO

We studied the COVID-19 impact in newly-diagnosed breast cancer (7,349 patients in 2019, and 5,563 in 2020). In 2020 there were two diagnostic drops: -37.2% (March-May), -15.8% (October-December). Early-stage at presentation (76.4% vs. 74.4%, p = 0.0013), conserving surgery (71.0% vs. 67.0%, p < 0.0001), chemotherapy (86.2% vs. 53.4%, p < 0.0001), and radiotherapy (65.7% vs. 42.1%, p < 0.0001) decreased in 2020 compared to 2019. COVID-19 occurred in 250 patients (4.49%). The time-dependent COVID-19 effect was associated with mortality (multivariable Cox analysis HR [95% CI] 2.26 [1.35-3.74]; p = 0.0018). Survival within the year of diagnosis was 97.6% in 2020 and 98.3% in 2019; 30-day mortality was 1.13% in 2020 (1.07 in uninfected patients), and 0.61% in 2019. The year of diagnosis lost its prognostic relevance after adjusting for stage and treatment. These findings emphasize the critical role of continuity of care, which was disrupted during the pandemic, and underscore the need for policies minimizing treatment initiation delay in newly diagnosed breast cancer patients.

RESUMO

Background: Increased success in the treatment of hematological cancers contributed to the increase of 5-year survival for most adolescent and young adults (AYAs) with these tumours. However, as 5-year survival increased, it became clear that AYA long-term survivors were at increased risk for severe late effects. Moreover, limited information on long-term cancer impact is available for AYAs, since most studies focused on children and adolescents. We aimed to assess various long-term outcomes on AYA survivors of hematological cancers. Methods: We selected patients diagnosed with a first primary hematological cancer between 1997 and 2006, in the Italian nationwide population-based cohort of AYA cancer survivors (i.e. alive at least 5 years after cancer diagnosis). Long-term outcomes of interest were: second malignant neoplasms (SMNs), hospitalizations and overall mortality. We calculated standardized incidence ratios (SIRs), standardized hospitalization rate ratios (SHRs) and standardized mortality rate ratios (SMRs). To study morbidity patterns over time, we modeled observed incidence rates by fitting flexible parametric models for nonlinear patterns and we used linear regression for linear patterns. Results: The study cohort included 5,042 AYA hematological cancer survivors of which 1,237 and 3,805 had a leukaemia and lymphoma diagnosis, respectively. AYA survivors were at substantially increased risk for SMN (SIR=2.1; 95%CI=1.7; 2.6), hospitalisation (SHR=1.5; 95%CI=1.5; 1.6), and mortality (SMR=1.4; 95%CI=1.2; 1.6) with differences between leukaemia and lymphoma survivors. The highest excess risks of hospitalisations were for infectious diseases, respiratory diseases, and diseases of blood and blood-forming organs. The morbidity pattern differs over time by morbidity type. Conclusions: Our results support the need for strict follow-up plans for survivors, and call for further study to better personalised follow-up plans for AYA cancer survivors.

RESUMO

BACKGROUND: Distal radius fractures (DRFs) are a common challenge in orthopaedic trauma care, yet for those fractures that are treated nonoperatively, strong evidence to guide cast treatment is still lacking. AIM: To compare the efficacy of below elbow cast (BEC) and above elbow cast (AEC) in maintaining reduction of manipulated DRFs. METHODS: We conducted a prospective, monocentric, randomized, parallel-group, open label, blinded, noninferiority trial comparing the efficacy of BEC and AEC in the nonoperative treatment of DRFs. Two hundred and eighty patients > 18 years of age diagnosed with DRFs were successfully randomized and included for analysis over a 3-year period. Noninferiority thresholds were defined as a 2 mm difference for radial length (RL), a 3° difference for radial inclination (RI), and volar tilt (VT). The trial is registered at Clinicaltrials.gov (NCT03468023). RESULTS: One hundred and forty-three patients were treated with BEC, and 137 were treated with AEC. The mean time of immobilization was 33 d. The mean loss of RL, RI, and VT was 1.59 mm, 2.83°, and 4.11° for BEC and 1.63 mm, 2.54°, and 3.52° for AEC, respectively. The end treatment differences between BEC and AEC in RL, RI, and VT loss were respectively 0.04 mm (95%CI: -0.36-0.44), -0.29° (95%CI: -1.03-0.45), and 0.59° (95%CI: -1.39-2.57), and they were all below the prefixed noninferiority thresholds. The rate of loss of reduction was similar. CONCLUSION: BEC performs as well as AEC in maintaining the reduction of a manipulated DRF. Being more comfortable to patients, BEC may be preferable for nonoperative treatment of DRFs.

RESUMO

Cancer patients are identified as fragile patients who are often immunodepressed and subject to secondary diseases. The Ada cohort comprises cancer survivors aged 15-39 years at diagnosis included in 34 Italian cancer registries. This study aimed to analyze the possible excess of non-cancer medicines use on the basis of the medicine database of the Ada cohort. Records of medicines present in the pharmaceutical flows collected by eight Lombardy cancer registries and used by patients with any type of cancer were extracted for the year 2012. Medicine consumption data were processed to assign a defined daily dose value and to evaluate the consumption of medicines belonging to different groups of the ATC (Anatomical Therapeutic Chemical) classification. The values were compared with values in the Lombardy population. Medicine consumption related to 8150 patients was analyzed, for a total of 632,675 records. ATC groups A and C for females and group N for both sexes showed significant increases. Group J for males and group M for females showed intermediate increases, and group H for both sexes showed smaller increases. This method allowed the identification of excess medicine use to reduce cancer therapy side effects and primary disease sequelae in this group of patients.

RESUMO

The stambomycins are a family of bioactive macrolides isolated from Streptomyces ambofaciens. Aside from two stereocenters installed through cytochrome P450 oxidations, their stereochemistry has been predicted by sequence analysis of the polyketide synthase. We report a synthesis of the C1-C27 fragment of stambomycin D, the spectroscopic data of which correlates well with that of the natural product, further validating predictive sequence analysis as a powerful tool for stereochemical assignment of complex polyketide natural products.

AIM: Recommendations for managing patients with nasopharyngeal carcinoma (NPC) in non-endemic areas are largely derived from studies conducted in endemic areas. We analysed the impact of treatment approaches on survival in non-endemic areas. METHODS: In an international, multicentre, retrospective study, we analyse consecutive patients with NPC diagnosed between 2004 and 2017 in 36 hospitals from 11 countries. Treatment was categorised as non-intensive (NIT), including radiotherapy alone or concomitant chemoradiotherapy (cCRT), and intensive (IT) including cCRT preceded by and/or followed by chemotherapy (CT). The impact of IT on overall survival (OS) and disease-free survival (DFS) was adjusted for all the available potential confounders. RESULTS: Overall, 1021 and 1113 patients were eligible for overall survival (OS) and disease-free survival (DFS) analyses, respectively; 501 and 554 with Epstein Barr-encoded RNA (EBER) status available. In the whole group, 5-year OS was 84% and DFS 65%. The use of NIT was associated with a risk of death or recurrence 1.37 times higher than patients receiving IT. Patients submitted to NIT and induction CT + concurrent concomitant chemo and three-dimensional Conformal Radiation Therapy (3DCRT) had a risk of death or recurrence 1.5 and 1.7 times higher than patients treated with induction CT + cCRT with intensity-modulated radiotherapy (IMRT), respectively. The IT had no impact on OS in neither patients with EBER+ nor in patients with EBER-; IT showed better DFS in EBER+ but not in patients with EBER-. CONCLUSIONS: In low-incidence areas, patients with NPC treated with induction CT followed by concurrent IMRT cCRT achieved the highest DFS rate. The benefit of IT on DFS was restricted to patients with EBER+, suggesting that additional therapy offers no advantages in EBER- cases.

RESUMO

Purpose: Rhabdomyosarcoma (RMS) has a worse prognosis in adults than in children, but there is evidence of a better outcome in the former if treated using a pediatric-like approach. This study describes treatment for RMS in patients more than 10 years old and examines to what extent treatment contributes to explain the different age-related survival observed and to what extent treatment centers impact treatment appropriateness. Methods: A retrospective population-based study was developed considering 104 RMS cases (excluding the pleomorphic subtype) diagnosed in Italy between 2000 and 2015. Patients were grouped by age (10-19 vs. 20-60 years old) and scored according to whether or not their chemotherapy was consistent with the schemes used in pediatric protocols (score 1 = chemotherapy in line with pediatric protocols). Treatment centers were grouped according to whether or not they have a pediatric-dedicated unit affiliated to the national pediatric oncology network (Associazione Italiana Ematologia Oncologia Pediatrica [AIEOP]). Results: Older patients were more likely to have tumors at unfavorable sites (p = 0.045). A treatment score of 1 was assigned to 85% of younger patients, but only to 32% of older patients (p < 0.001). Furthermore, the proportion of score 1 was higher in younger patients treated in centers with an AIEOP Unit. A multivariate model confirmed age as a significant prognostic factor (Hazard rate ratio [HR] = 2.06; p = 0.04) and showed a significant impact of treatment on survival (HR = 2.13; p = 0.03). Conclusions: Adult RMS patients are still relatively unlikely to be treated with pediatric protocols and in centers with a pediatric oncology expertise. This may explain the survival gap between older and younger patients.

RESUMO

A variety of 3-vinyl-substituted imidazo[1,5-a]indole derivatives were synthesized by intramolecular Pd-catalyzed cyclization of the title allenamides through either a domino carbopalladation/exo-cyclization process or a novel hydroamination reaction that proceeds smoothly under microwave irradiation. Both the observed pathways involve a π-allyl-palladium(II) complex arising from insertion of the allene group into a palladium(II) species, the latter being formed in situ by the intervention of an aryl iodide or of the N-H group. In both cases, the role of nucleophile is covered by the indole nitrogen.
