Abstract

Background

The aim of the study was to assess the proportion of women that would be classified as at above-average risk of breast cancer based on the 10 year-risk prediction of the Slovenian breast cancer incidence rate (S-IBIS) program in two presumably above-average breast cancer risk populations in age group 40-49 years: (i) women referred for any reason to diagnostic breast centres and (ii) women who were diagnosed with breast cancer aged 40–49 years. Breast cancer is the commonest female cancer in Slovenia, with an incidence rate below European average. The Tyrer-Cuzick breast cancer risk assessment algorithm was recently adapted to S-IBIS. In Slovenia a tailored mammographic screening for women at above average risk in age group 40–49 years is considered in the future. S-IBIS is a possible tool to select population at above-average risk of breast cancer for tailored screening.

Patients and methods

In 357 healthy women aged 40–49 years referred for any reason to diagnostic breast centres and in 367 female breast cancer patients aged 40–49 years at time of diagnosis 10-years breast cancer risk was calculated using the S-IBIS software. The proportion of women classified as above-average risk of breast cancer was calculated for each subgroup of the study population.

Results

48.7% of women in the Breast centre group and 39.2% of patients in the breast cancer group had above-average 10-year breast cancer risk. Positive family history of breast cancer was more prevalent in the Breast centre group (p < 0.05).

Conclusions

Inclusion of additional risk factors into the S-IBIS is warranted in the populations with breast cancer incidence below European average to reliably stratify women into breast cancer risk groups.

Abstract

Background

Breast hematoma is an often underrated and disregarded post-procedural complication in the literature. Current treatment modalities are comprised of either surgical or expectant therapy, while percutaneous procedures play a smaller role in their treatment. We aimed to examine the efficacy of vacuum-assisted evacuation (VAE) in the treatment of clinically significant large breast hematomas as an alternative to surgery.

Patients and methods

We retrospectively analysed patients that underwent breast interventions (surgical and percutaneous), who later developed clinically significant large hematomas and underwent a trial of VAE of hematoma in our hospital within the period of four years. Patient and procedure characteristics were acquired before and after VAE. Success of intervention was based on ≥ 50% clearance of hematoma volume and patients’ subjective resolution of symptoms. All patients were followed clinically and by ultrasound if needed at different intervals depending on the severity of presenting symptoms.

Results

Eleven patients were included in the study. The mean largest diameter of hematomas was 7.9 cm and mean surface area was 32.4 cm2. The mean duration of the procedure was 40.5 min. In all patients VAE of hematoma was implemented successfully with no complications. Control visits showed no major residual hematoma or seroma formation.

Conclusions

Our results show that VAE of hematoma can be implemented as a safe alternative to surgery in large, clinically significant hematomas, regardless of aetiology or duration. The procedure carries less risk, stress and cost with the added benefit of outpatient treatment when compared to surgical treatment.

Abstract

Background

Stereotactic ablative radiotherapy (SABR) is effective for thoracic cancer and metastases; however, adverse effects are greater for central tumors. We evaluated factors affecting outcomes and toxicities after SABR for patients with primary lung and oligometastatic tumors.

Patients and methods

We retrospectively identified consecutive patients with centrally located lung tumors that were treated at our hospital from 2009-2016. The effects of patient, disease, and treatment-related parameters on local control (LC), overall survival (OS), and toxicity-free survival (TFS) were evaluated with multivariate analyses.

Results

Among 65 consecutive patients identified with 70 centrally located tumors, 20 tumors (28%) were reirradiated. Median (range) total dose for all tumors was 55 (30–60) Gy in 5 (3–10) fractions. Radiographic complete response was obtained in 43 lesions (61%). None of the analyzed factors were correlated with complete response. After a median follow-up of 57 (95% CI, 48–65) months, 10 tumors (14%) relapsed and 37 patients (57%) died; the actuarial 2- and 5-year OS rates were 52% and 28%, respectively. Median OS was significantly lower in patients with grade 3 or higher toxicity vs. lower toxicity (5 vs. 39 months; P < 0.001). Among 17 severe toxicities, 5 were grade 5, and 3 of them were reirradiated to the same field. Grade 3 to 5 TFS was lower with vs. without reirradiation (2-year TFS, 63% vs. 96%; P = 0.02).

Conclusions

Our study showed that modern SABR is effective for central lung tumors, and toxicities are acceptable. SABR for reirradiated central lung lesions and possibly for lesions abutting the tracheobronchial tree may result in higher risk of serious toxicities.

Abstract

COVID-19 has become a global pandemic and requires the whole world to respond together. There is no specific antiviral treatment recommended at present for COVID-19. The patients must receive the supportive care to help relieve the symptoms and ensure appropriate infection control. Whether or not to use corticosteroids clinically caused controversy. This article has summarized previous researches about the using of corticosteroids in other viral pneumonia, related clinical data in COVID-19, and recommendations in Chinese guideline.

Abstract

On March 11, 2020, the WHO declared that coronavirus disease 2019 (COVID-19) can be characterized as a pandemic based on the alarming levels of spread and severity and on the alarming levels of inaction. COVID-19 has received worldwide attention as emergency, endangering international public health and economic development. There is a growing body of literatures regarding severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) as well as COVID-19. This review will focus on the latest advance of epidemiology, pathogenesis, and clinical characteristics about COVID-19. Meanwhile, tuberculosis (TB) remains the leading representative respiratory tract communicable disease threatening public health. There are limited data on the risk of severe disease or outcomes in patients with concurrence of TB and COVID-19. Nevertheless, co-infection of some virus would aggravate TB, such as measles. And tuberculosis and influenza co-infection compared with tuberculosis single infection was associated with increased risk of death in individuals. This review will also introduce the characteristics about the concurrence of TB and emerging infectious diseases to provide a hint to manage current epidemic.

Abstract

Background

Electrochemotherapy is an effective treatment of colorectal liver metastases and hepatocellular carcinoma (HCC) during open surgery. The minimally invasive percutaneous approach of electrochemotherapy has already been performed but not on HCC. The aim of this study was to demonstrate the feasibility, safety and effectiveness of electrochemotherapy with percutaneous approach on HCC.

Patient and methods

The patient had undergone the transarterial chemoembolization and microwave ablation of multifocal HCC in segments III, V and VI. In follow-up a new lesion was identified in segment III, and recognized by multidisciplinary team to be suitable for minimally invasive percutaneous electrochemotherapy. The treatment was performed with long needle electrodes inserted by the aid of image guidance.

Results

The insertion of electrodes was feasible, and the treatment proved safe and effective, as demonstrated by control magnetic resonance imaging.

Conclusions

Minimally invasive, image guided percutaneous electrochemotherapy is feasible, safe and effective in treatment of HCC.

Abstract

Background

Effect of isocitr ate dehydrogenase 1 (IDH1) mutation in neovascularization might be linked with tissue perfusion in gliomas. At present, the need of injection of contrast agent and the increasing scanning time limit the application of perfusion techniques. We used a simplified intravoxel incoherent motion (IVIM)-derived perfusion fraction (SPF) calculated from diffusion-weighted imaging (DWI) using only three b-values to quantitatively assess IDH1-linked tissue perfusion changes in WHO grade II-III gliomas (LGGs). Additionally, by comparing accuracy with dynamic contrast-enhanced (DCE) and full IVIM MRI, we tried to find the optimal imaging markers to predict IDH1 mutation status.

Patients and methods

Thirty patients were prospectively examined using DCE and multi-b-value DWI. All parameters were compared between the IDH1 mutant and wild-type LGGs using the Mann–Whitney U test, including the DCE MRI-derived K trans, v e and v p, the conventional apparen t diffusion coefficient (ADC 0,1000), IVIM-de rived perfusion fraction (f), diffusion coefficient (D) and pseudo-diffusion coefficient (D*), SPF. We evaluated the diagnostic performance by receive r operating characteristic (ROC) analysis.

Results

Significant differences were detected between WHO grade II-III gliomas for all perfusion and diffusion parameters (P < 0.05). When compared to IDH1 mutant LGGs, IDH1 wild-type LGGs exhibited significantly higher perfusion metrics (P < 0.05) and lower diffusion metrics (P < 0.05). Among all parameters, SPF showed a higher diagnostic performance (area under the curve 0.861), with 94.4% sensitivity and 75% specificity.

Conclusions

DWI, DCE and IVIM MRI may noninvasively help discriminate IDH1 mutation statuses in LGGs. Specifically, simplified DWI-derived SPF showed a superior diagnostic performance.

Abstract

Invasive fungal disease (IFD) is one of the most serious complications of therapy in patients with immune suppression. It particularly concerns patients treated for malignant hematological diseases, immune deficiencies, or undergoing hematopoietic cell transplantation (HCT). Development of IFD can abrogate the effect of previous therapy and contributes to dismal outcome of the underlying disease. The Working Group consisting of members of the Polish Society of Hematology and Blood Transfusion, the Polish Society of Pediatric Oncology and Hematology, and the Polish Adult Leukemia Study Group has prepared recommendations for the diagnostic and therapeutic management of IFD in adults and children. This paper presents the current recommendations for patients in immune suppression treated in Polish pediatric and adult hematology and HCT centers, based on the guidelines of the European Conference on Infections in Leukaemia (ECIL) 2015–2019. Levels of diagnosis of IFD (possible, probable, and proven) and antifungal management (prophylaxis, as well as empirical and targeted therapies) are declared according to updated international criteria of the European Organization for Research and Treatment of Cancer and the Mycoses Study Group (EORTC/MSG) 2019. Patients with primary diagnosis of acute lymphoblastic leukemia, acute myeloblastic leukemia, severe aplastic anemia, chronic granulomatous disease, and severe combined immunodeficiency, as well as patients after allogeneic HCT, are included in the high-risk groups for development of IFD. For these patients, antifungal prophylaxis based on azoles or micafungin is recommended. In empirical therapy, caspofungin or liposomal/lipid formulas of amphotericin B are recommended. The Working Group has discouraged the use of itraconazole in capsules and amphotericin deoxycholate. Detailed guidelines for first- and second-line targeted therapies for invasive candidiasis, aspergillosis, mucormycosis, fusariosis, and scedosporiosis, as well as the principles of the recommended dosing of antifungals, are presented in this paper.

Abstract

Proton pump inhibitors (PPIs) are drugs commonly used for many diseases of the gastrointestinal tract, such as gastroesophageal reflux disease, erosive esophagitis, and peptic ulcers of the stomach and duodenum. Used for about 30 years, they are currently the most effective drugs that reduce the gastric secretion of hydrochloric acid. However, a dramatic increase in their consumption has been recently observed. Very often, they are used not in accordance with the guidelines. The consequences of the long-term use of PPIs may be various, with the most common side effects being bone fractures, cardiovascular events, recurrent infections, and vitamin and mineral deficiencies. Case report: An 82-year-old and a 58-year-old patients who had been taking omeprazole, a PPI for several years, developed vitamin B12 and iron deficiency anemia. Both patients were administered PPI orally for nonspecific dyspeptic symptoms. An evaluation of the gastrointestinal tract did not reveal the evident causes of gastrointestinal blood loss. They were also screened negative for Helicobacter pylori infection. Conclusions: There are no definitive pieces of evidence that the long-term use of PPIs can induce anemia, but our cases strongly suggest this thesis. Physicians should be aware of this potential side effect and consider monitoring in high-risk patients.
