IntroductionThe elderly, who suffer from multiple chronic diseases, represent a substantial proportion of Emergency Department (ED) frequent users, thus contributing to ED overcrowding, although they could benefit from other health care facilities, if those were available. The aim of this study was to evaluate and characterize hospital visits of older patients (age 65 or greater) to the ED of a university teaching hospital in Rome from the 1st of January to the 31st of December 2014, in order to identify clinical and social characteristics potentially associated with “elderly frequent users”.Material and MethodsA retrospective study was performed during the calendar year 2014 (1st January 2014 – 31st December 2014) analyzing all ED admissions to the University Hospital of Rome Tor Vergata. Variables collected included age, triage code, arrival data, discharge diagnosis, and visit outcome. We performed a risk analysis using univariate binary logistic regression models.ResultsA total number of 38,016 patients accessed the ED, generating 46,820 accesses during the study period, with an average of 1.23 accesses for patient. The elderly population represented a quarter of the total ED population and had an increased risk of frequent use (OR 1.5: CI 1.4–1.7) and hospitalization (OR 3.8: CI 3.7–4). Moreover, they showed a greater diagnostic complexity, as demonstrated by the higher incidence of yellow and red priority codes compared to other ED populations (OR 3.1: CI 2.9–3.2).DiscussionOlder patients presented clinical and social characteristics related to the definition of “elderly frail frequent users”. The fact that a larger number of hospitalizations occurred in such patients is indirect evidence of frailty in this specific population, suggesting that hospital admissions may be an inappropriate response to frailty, especially when continued care is not established.ConclusionEnhancement of continuity of care, establishment of a tracking system for those who are at greater risk of visiting the ED and evaluating fragile individuals should be the highest priority in addressing ED frequent usage by the elderly.
Despite advances in treatment, up to 30% of patients with early breast cancer (BC) experience distant disease relapse. However, a comprehensive understanding of tumor spread and site-specific recurrence patterns remains lacking. This retrospective case-control study included 103 consecutive patients with metastatic BC admitted to our institution (2000–2013). Cases were matched according to age, tumor biology, and clinicopathological features to 221 patients with non-metastatic BC (control group). The median follow-up period among the 324 eligible patients was 7.3 years. While relatively low values for sensitivity (71%) and specificity (56%) were found for axillary lymph node (ALN) involvement as an indicator of risk and pattern of distant relapse, nodal status remained the most powerful predictor of metastases (OR: 3.294; CL: 1.9–5.5). Rates of dissemination and metastatic efficiency differed according to molecular subtype. HER2-positive subtypes showed a stronger association with systemic spread (OR: 2.127; CL: 1.2–3.8) than other subgroups. Classification as Luminal or Non-Luminal showed an increased risk of lung and distant nodal recurrence, and a decreased risk in bone metastases in the Non-Luminal group (OR: 2.9, 3.345, and 0.2, respectively). Tumors with HER2 overexpression had a significantly high risk for distant relapse (OR: 2.127) compared with HER2-negative tumors and also showed higher central nervous system (CNS) and lung metastatic potential (OR: 5.6 and 2.65, respectively) and low risk of bone disease progression (OR: 0.294). Furthermore, we found significant associations between biological profiles and sites of recurrence. A new process of clinical/diagnostic staging, including molecular subtypes, could better predict the likelihood of distant relapses and their anatomical location. Recognition and appreciation of clinically distinct molecular subtypes may assist in evaluation of the probability of distant relapses and their sites. Our analysis provides new insights into management of metastatic disease behavior, to lead to an optimal disease-tailored approach and appropriate follow-up.
BackgroundExpression levels of CD133, a cancer stem cell marker, and of the α-subunit of the dystroglycan (α-DG) complex, have been previously reported to be altered in colorectal cancers.MethodsExpression levels of CD133 and α-DG were assessed by immunohistochemistry in a series of colon cancers and their prognostic significance was evaluated.ResultsScattered cells positive for CD133 were rarely detected at the bases of the crypts in normal colonic mucosa while in cancer cells the median percentage of positive cells was 5% (range 0–80). A significant correlation was observed with pT parameter and tumor stage but not with tumor grade and N status. Recurrence and death from disease were significantly more frequent in CD133-high expressing tumors and Kaplan-Meier curves showed a significant separation between high vs low expressor groups for both disease-free (p = 0.002) and overall (p = 0.008) survival.Expression of α-DG was reduced in a significant fraction of tumors but low α-DG staining did not correlate with any of the classical clinical-pathological parameters. Recurrence and death from the disease were significantly more frequent in α-DG-low expressing tumors and Kaplan-Meier curves showed a significant separation between high vs low expressor tumors for both disease-free (p = 0.02) and overall (p = 0.02) survival. Increased expression of CD133, but not loss of α-DG, confirmed to be an independent prognostic parameters at a multivariate analysis associated with an increased risk of recurrence (RR = 2.4; p = 0.002) and death (RR = 2.3; p = 0.003).ConclusionsLoss of α-DG and increased CD133 expression are frequent events in human colon cancer and evaluation of CD133 expression could help to identify high-risk colon cancer patients.
According to this study, sentinel nodal ratio and BC subtypes as per ER, PR, and HER2 status significantly predicted the likelihood of additional lymphatic involvement. Validation of these parameters in prospective studies is indicated, and may help individualize treatment modalities.
Aim: Acute post-operative pain following modified radical mastectomy (MRM) in patients with breast cancer is challenging for anesthesiologists. This study aimed to prospectively compare the quality outcome of interfascial plane blocks performed with ultrasound guidance, and evaluate the consequences of sharing tasks with the breast surgeon. Patients and Methods: The study involved 255 patients scheduled for unilateral MRM, who were divided into two groups: Pecs group: General anesthesia plus ultrasound-guided modified pectoral nerves blocks type I and II, including serratus and parasternal infiltration according to surgical requirements; and Control group: general anesthesia only. Quality was evaluated based on perioperative opioid consumption, reported pain intensity, rescue analgesic requirement, side-effects and length of hospital stay. Moreover, a breast surgeon with expertise in ultrasound-guided breast biopsy was trained to perform the blocks. The patient benefits from regional anesthesia delivered by a non-anesthesiologist were assessed. Results: Significant reductions were noted in all of the following: Intraoperative opioid consumption (p<0.001), Numerating Rating Scale pain scores taken 0 and 24 h after surgery (p<0.001), post-operative analgesic administration (p<0.001), nausea and vomiting at 0, 6, and 12-h intervals (p<0.05), and hospital stay (p<0.001) were observed in the Pecs group compared with the control group. Furthermore, data obtained from patients receiving the block from the surgeon showed comparable benefits with no complications. Conclusion: Interfascial plane blocks may be an important alternative protocol in MRM, enhancing patient safety and cost benefits. Improvements in cross-disciplinary expertise through flexibility in the training of professionals with other backgrounds may provide effective analgesia and favorable outcomes.
These findings demonstrate that CD133 immunostaining is a useful predictor of high risk progression in stage I CRC patients and might help to identify patients eligible for adjuvant chemotherapy.
Background/Aim: Positron emission tomography/ computed tomography (PET/CT) with 18 F-fluorodeoxyglucose (18F-FDG) has recently been used to investigate lymph node (LN) metastases and several predictive features in patients with breast cancer (BC). The aim of this study was to assess the value of this non-invasive imaging procedure for axillary staging. Patients and Methods: Fifty patients with early primary unilateral, locally advanced, or recurrent invasive operable BC were enrolled. All patients underwent preoperative 18F-FDG PET/CT, and the results were compared with the histopathology of dissected axillary LNs and their biological and immunohistochemical characteristics. The diagnostic performance of 18F-FDG PET/CT in detecting LN metastases from primary or recurrent BC was analyzed. The mean values of the initial PET/CT parameters, including the primary tumour (SUV T) and ipsilateral axillary LNs (SUV LN), were compared with the clinicopathological features of patients to determine their usefulness for predicting clinical interactions. Results: The sensitivity, specificity, overall accuracy, positive predictive value, and negative predictive value of 18F-FDG PET/CT for axillary LN staging were 87%, 90%, 88%, 93%, and 82%, respectively. Bivariate analyses showed strong interactions of nuclear grade (p=0.05), progesterone receptor expression (p=0.001), Ki-67 index (0.027), and local relapse with the SUV T. A high SUV LN value was significantly correlated with a higher nuclear grade score (p=0.05), oestrogen receptor negativity (p=0.001), progesterone receptor negativity (p=0.014), a high Ki-67 index (>20%; p=0.048), LN metastasis (p<0.001), a basal tumour (p=0.04), and locoregional recurrence (p<0.001). Conclusion: PET/CT is a reproducible, non-invasive imaging modality that is useful for evaluating a primary BC mass and its relationship with metastatic axillary LNs, thereby predicting tumour behaviour and guiding clinical practice.
Background: Most cases of breast lesions of uncertain malignant potential (B3) undergo surgical intervention. We aimed to analyze the outcome of B3 lesion subtypes in a large series of screen-detected cases. Methods: We screened 2,986 core needle biopsies to classify B3 lesions. Positive predictive values (PPVs) for malignancy were calculated for a comprehensive risk characterization according to clinicopathologic and morphologic variables. Results: B3 lesions comprised 35% atypical ductal hyperplasia (PPV = 20%), 16.7% flat epithelial atypia (PPV = 12%), 22.7% lobular neoplasia (PPV = 16.2%), 9% papillary lesion (PPV = 18.5%), 8.6% phyllodes tumor (PPV = 3.8%), and 8% radial scars (PPV = 4.1%) based on histopathologic diagnosis. Upgrade rates were 15.9% for calcifications, 13.7% for mass lesions, and 16.7% for architectural deformities, with 8.3% of malignant lesions classified as ductal carcinoma in situ and 6.7% as invasive cancers (PPV = 15%). Conclusion: B3 lesions entail a heterogeneous risk of malignancy, and careful radiologic–pathologic correlation is required for optimal treatment.
