ABSTRACT
PURPOSE: Accurate evaluation of breast cancer on bioptic samples is of fundamental importance to guide therapeutic decisions, especially in the neoadjuvant or metastatic setting. We aimed to assess concordance for oestrogen receptor (ER), progesterone receptor (PR), c-erbB2/HER2 and Ki-67. We also reviewed the current literature to evaluate our results in the context of the data available at present. METHODS: We included patients who underwent both biopsy and surgical resection for breast cancer at San Matteo Hospital, Pavia, Italy, between January 2014 and December 2020. ER, PR, c-erbB2, and Ki-67 immunohistochemistry concordance between biopsy and surgical specimen was evaluated. ER was further analysed to include the recently defined ER-low-positive in our analysis. RESULTS: We evaluated 923 patients. Concordance between biopsy and surgical specimen for ER, ER-low-positive, PR, c-erbB2 and Ki-67 was, respectively, 97.83, 47.8, 94.26, 68 and 86.13%. Cohen's κ for interobserver agreement was very good for ER and good for PR, c-erbB2 and Ki-67. Concordance was especially low (37%) in the c-erbB2 1 + category. CONCLUSION: Oestrogen and progesterone receptor status can be safely assessed on preoperative samples. The results of this study advise caution in interpreting biopsy results regarding ER-low-positive, c-erbB2/HER and Ki-67 results due to a still suboptimal concordance. The low concordance for c-erbB2 1 + cases underlines the importance of further training in this area, in the light of the future therapeutic perspectives.

Background: The era of establishing tyrosine kinase inhibitors (TKIs) in the treatment of chronic myeloid leukemia (CML) changed the outcome and the course of this life-threatening malignancy. People suffering from CML have now a better prognosis and a longer life expectancy due to the development of TKIs, even if it requires long-term, often lifelong, treatments that are nonetheless associated with improved Health-related Quality of life (HRQoL). However, data on the effects of TKIs on HRQoL are not always systematic; sometimes the data have been obtained by studies different from RCTs, or without a clear definition of what HRQoL is. The main purpose of this systematic review is to summarize all randomized-controlled trials (RCTs) including HRQoL as main or secondary outcome in patients with CML treated with TKIs or with TKIs plus an add-on treatment. Methods: A systematic review has been conducted by searching the relevant papers in PubMed/Medline and Web of Science with the following keywords: "quality of life" OR "health-related quality of life" OR "QoL" OR "HRQoL" OR "H-QoL" AND "chronic myeloid leukemia". Interval was set from January 2000 to December 2020. Results: 40 papers were identified through the search. Out of them, 7 RCTs were included. All the studies used standardized measures to assess HRQoL, even not always specific for CML. 5 RCTs randomized subjects to 2 or 3 arms to evaluate the effects of TKIs of the first, second and third generation in monotherapy. 2 RCTs randomized subjects to TKI therapy plus an add-on treatment versus TKI therapy as usual. The results of all these trials were examined and discussed. Conclusion: All the included RCTs pointed out significant findings regarding the positive effects of TKIs on HRQoL of people with CML, both when they were used in monotherapy or, notably, with an add-on treatment to enhance TKIs effects.
ABSTRACT
PURPOSE: Breast lesions classified as of "uncertain malignant potential" represent a heterogeneous group of abnormalities with an increased risk of associated malignancy. Clinical management of B3 lesions diagnosed on vacuum-assisted breast biopsy (VABB) is still challenging: surgical excision is no longer the only available treatment and VABB may be sufficient for therapeutic excision. The aim of the present study is to evaluate the positive predictive value (PPV) for malignancy in B3 lesions that underwent surgical excision, identifying possible upgrading predictive factors and characterizing the malignant lesions eventually diagnosed. These results are compared with a subset of patients with B3 lesions who underwent follow-up. METHODS: A total of 1250 VABBs were performed between January 2006 and December 2017 at our center. In total, 150 B3 cases were diagnosed and 68 of them underwent surgical excision. VABB findings were correlated with excision histology. A PPV for malignancy for each B3 subtype was derived. RESULTS: The overall PPV rate was 28%, with the highest upgrade rate for atypical ductal hyperplasia (41%), followed by classical lobular neoplasia (29%) and flat epithelial atypia (11%). Only two cases of carcinoma were detected in the follow-up cohort, both associated with atypical ductal hyperplasia at VABB. CONCLUSION: Open surgery is recommended in case of atypical ductal hyperplasia while, for other B3 lesions, excision with VABB only may be an acceptable alternative if radio-pathological correlation is assessed, if all microcalcifications have been removed by VABB, and if the lesion lacks high-risk cytological features. KEY POINTS: ⢠Surgical treatment is strongly recommended in case of ADH, while the upgrade rate in case of pure FEA, especially following complete microcalcification removal by VABB, may be sufficiently low to advice surveillance as a management strategy. ⢠The use of 11-G- or 8-G-needle VABB, resulting in possible complete diagnostic excision of the lesion, can be an acceptable alternative in case of RS, considering open surgery only for selected high-risk patients. ⢠LN management is more controversial: surgical excision may be recommended following classical LN diagnosis on breast biopsy if an additional B3 lesion is concurrently detected while in the presence of isolated LN with adequate radiological-pathological correlation follow-up alone could be an acceptable option.

Clinical experience has shown an increase of behavioural and mood symptoms, especially in the areas of aggressiveness, sexuality and obsessiveness, during the late stages of ALS. The lack of conclusive data concerning these symptoms prompted us to assess the psychological aspects of ALS patients in advanced stages of the disease. Moreover, we evaluated the personality of their caregivers in order to analyse the relationship between the pair. For these purposes, we studied 10 patients with ALS in late stages (tracheostomized for 36 months) and their caregivers using a questionnaire specifically elaborated for patients' communication limits. To assess the state of anxiety and depression of both patients and caregivers, we used the Hospital Anxiety and Depression Scale (HADS). To investigate caregivers' personality, we administered the Big Five Questionnaire (BFQ). Data showed a trend of aggression and high level of obsessiveness in ALS patients, associated with several clinical characteristics. High levels of anxiety emerged in both patients and caregivers. Regarding BFQ, caregivers obtained higher scores in the dimension of Conscientiousness and very low scores in Extraversion and Emotional Stability. In conclusion, the study showed a potential and considerable effect of the long duration of ALS on patients' personality and caregivers' distress.

Marfan Syndrome (MFS) is an autosomal dominant disorder of the connective tissue due to mutations of Fibrillin-1 gene (FBN1) in more than 90% of cases and Transforming Growth Factor-Beta-Receptor2 gene (TGFB2R) in a minority of cases. Genotyping is relevant for diagnosis and genotype-phenotype correlations. We describe the FBN1 genotypes and related phenotypes of 81 patients who were referred to our attention for MFS or Marfan-like phenotypes. Patients underwent multidisciplinary pertinent evaluation in the adult or paediatric setting, according to their age. The diagnosis relied on Ghent criteria. To optimise DHPLC analysis of the FBN1 gene, all coding regions of the gene were directly sequenced in 19 cases and 10 controls: heterozygous amplicons were used as true positives. DHPLC sensitivity was 100%. Then, DHPLC was used to screen 62 other cases. We identified 74 FBN1 mutations in 81 patients: 64 were novel and 17 known. Of the 81 mutations, 41 were missense (50.6%), 27, either nonsense or frameshift mutations and predicted a premature termination codon (PTC) (33%), 11 affected splice sites (13.6%), and two predicted in-frame deletions (2.5%). Most mutations (67.9%) occurred in cbEGF-like modules. Genotype was clinically relevant for early diagnosis and conclusion of the diagnostic work-up in patients with incomplete or atypical phenotypes.

Central diabetes insipidus (CDI) has been linked to vascular central nervous system damage, although the pathophysiology of the mechanism has never been perfectly understood. Indeed, the vascular system of human pituitary gland has rarely been the subject of rigorous investigation except at postmortem. Recently, studies of pituitary gland blood supply have been carried out by means of a time evaluation of pituitary gland enhancement with noninvasive dynamic magnetic resonance (MR) imaging after contrast medium injection. In the present study, we decided to investigate the status of posterior pituitary blood supply by evaluating vascular pituitary patterns in a group of 19 patients with idiopathic CDI in whom previous standard MR imaging had failed to identify causal specific lesions. The control group was composed of 55 subjects with a median age of 12 yr (range, 4.2-17 yr) who had idiopathic isolated GH deficiency and normal pituitary morphology and 15 young adults (18-25 yr) who had normal pituitary gland and no endocrine dysfunction. Nineteen patients (12 females and seven males), ranging in age at the time of diagnosis of CDI from 0.5-14.9 yr (median, 5 yr), were examined with dynamic MR imaging between 1990 and 1997 at a median age of 14.1 yr (range, 5.0-26.3 yr). CDI was diagnosed according to clinical findings of polyuria and polydipsia, water deprivation test, and desmopressin acetate therapeutic trial. All of the patients had permanent CDI and were being treated with satisfactory results with desmopressin, two to three times daily, either intranasally or orally. The previous MR imaging findings of the 19 CDI patients had shown the absence of posterior pituitary hyperintensity, normal pituitary stalk, and normal anterior pituitary size. Enhancement of the straight sinus, representing a temporal reference point and occurring in normal subjects simultaneously to that of the posterior pituitary gland, was observed in all subjects after iv gadopentetate dimeglumine administration, with no substantial differences between patients and controls. However, the enhancement of the posterior pituitary lobe occurred simultaneously with the enhancement of the straight sinus in all of the controls but in only 14 of the 19 patients with CDI. In the remaining five patients, the enhancement of the straight sinus was not associated with the expected contrast enhancement of the posterior pituitary gland, suggesting abnormal blood supply to the posterior pituitary lobe. This is in keeping with vascular impairment of the inferior hypophyseal artery system and suggests that abnormal blood supply to the posterior pituitary gland is associated with what, until now, has been considered idiopathic CDI.

BACKGROUND: Patients with Turner's syndrome have an increased risk of cardiac death caused by aortic disease. Consensus has not been reached about the best method to image the aorta in this syndrome. AIM: This present study aimed: (i) to evaluate thoracic and abdominal aortic dimensions by two-dimensional echo (2-DE) and magnetic resonance imaging (MRI) and (ii) to assess agreement between 2-DE and MRI measurements. MATERIAL AND METHODS: Among 75 kariotypically proven Turner's syndrome patients, 59 (79%) (mean age: 22 +/- 7 years) underwent a 2-DE and an MRI study of the thoracic and proximal abdominal aorta. The aortic root (AR), the sino-tubular aortic junction (STJ), the first part of the ascending thoracic aorta (AscTA), the aortic arch (AArch), the descending thoracic aorta (DTAp) a few centimetres below the isthmus and the abdominal aorta (AbA) were analysed. The Bland and Altman method and Lin's concordance correlation coefficient were utilized to compare 2-DE and MRI aortic dimensions. RESULTS: Compared to MRI, feasibility of aortic imaging by 2-DE was identical at AR level, but lower when measuring distal aorta (88% at DTAp and 91.5% at AbA level versus 100%). The 2-DE and MRI showed a very slight difference between measurements and a high concordance correlation coefficient at the level of AR and AscTA; correlations were weaker at the other aortic levels. Absolute differences calculated at each measurement level showed that concordance (defined as differences within 1 mm between 2-DE and MRI absolute measures) was highest at AR (45.6%) and AscTA (28%) level and lowest at STJ (12.2%) level. The 2-DE overestimated aortic arch diameters in approximately 70% of cases, whereas at the remaining aortic levels MRI measurements were usually 1 mm higher compared to the corresponding 2-DE values. CONCLUSIONS: Concordance between 2-DE and MRI was found to be very good at the AR and AscTA levels. Because the risk of aortic complication is higher when AR and proximal thoracic aorta are dilated, 2-DE may be considered a useful method to screen for aortic disease and a good choice to follow proximal aortic dimensions over time in Turner's syndrome patients.

OBJECTIVES: We sought to evaluate the capability of the right ventricle to regain normal morphology and function after pulmonary endarterectomy, to correlate right ventricular reverse remodeling with functional status, and to identify independent predictors of clinical failure after surgical intervention. METHODS: From December 2000 through August 2003, 45 patients underwent isolated pulmonary endarterectomy. Morphology and function of the right ventricle were studied by using a combination of right heart catheterization, cardiac magnetic resonance, and transthoracic echocardiography. Functional status was evaluated by using New York Heart Association class. Full preoperative data were available for 37 candidates. All patients were evaluated before discharge, at 3 months, and at 1, 2, and 3 years postoperatively using the same modalities. RESULTS: Immediately after surgical intervention, right ventricular cavitary dimensions decreased significantly, and tricuspid regurgitation radically improved. Right ventricular ejection fraction and functional status improved and right ventricular hypertrophy reversed over a longer time period. Higher ventricular dimensions and lower ejection fraction of the right ventricle were associated with poorer functional status at any time postoperatively. At discharge, pulmonary vascular resistance of greater than 509 dyne x sec x cm(-5) and right ventricular ejection fraction of 24% or less predicted clinical failure at 12 months' follow-up. CONCLUSIONS: After pulmonary endarterectomy, the right ventricle recovers and maintains normal architecture and function over time, regardless of the severity of preoperative disease. Accurate preoperative evaluation of the hemodynamics and anatomy of the thromboembolic lesions are mandatory. If pulmonary endarterectomy is not expected to decrease pulmonary vascular resistance to less than 509 dyne x sec x cm(-5), indication for surgical intervention needs to be carefully evaluated.
