Magnetic resonance imaging tumor regression shrinkage patterns after neoadjuvant chemotherapy in patients with locally advanced breast cancer: correlation with tumor biological subtypes and pathological response after therapy

The objective of this study is to analyze magnetic resonance imaging shrinkage pattern of tumor regression after neoadjuvant chemotherapy and to evaluate its relationship with biological subtypes and pathological response. We reviewed the magnetic resonance imaging studies of 51 patients with single mass-enhancing lesions (performed at time 0 and at the II and last cycles of neoadjuvant chemotherapy). Tumors were classified as Luminal A, Luminal B, HER2+, and Triple Negative based on biological and immunohistochemical analysis after core needle biopsy. We classified shrinkage pattern, based on tumor regression morphology on magnetic resonance imaging at the II cycle, as concentric, nodular, and mixed. We assigned a numeric score (0: none; 1: low; 2: medium; 3: high) to the enhancement intensity decrease. Pathological response on the surgical specimen was classified as complete (grade 5), partial (grades 4-3), and non-response (grades 1-2) according to Miller and Payne system. Fisher test was used to relate shrinkage pattern with biological subtypes and final pathological response. Seventeen patients achieved complete response, 25 partial response, and 9 non-response. A total of 13 lesions showed nodular pattern, 20 concentric, and 18 mixed. We found an association between concentric pattern and HER2+ (p < 0.001) and mixed pattern and Luminal A lesions (p < 0.001). We observed a statistical significant correlation between concentric pattern and complete response (p < 0.001) and between mixed pattern and non-response (p = 0.005). Enhancement intensity decrease 3 was associated with complete response (p < 0.001). Shrinkage pattern and enhancement intensity decrease may serve as early response indicators after neoadjuvant chemotherapy. Shrinkage pattern correlates with tumor biological subtypes

Secondary cytomegalovirus infections: How much do we still not know? Comparison of children with symptomatic congenital cytomegalovirus born to mothers with primary and secondary infection

Congenital cytomegalovirus (cCMV) infection can follow primary and secondary maternal infection. Growing evidence indicate that secondary maternal infections contribute to a much greater proportion of symptomatic cCMV than was previously thought. We performed a monocentric retrospective study of babies with cCMV evaluated from August 2004 to February 2021; we compared data of symptomatic children born to mothers with primary or secondary infection, both at birth and during follow up. Among the 145 babies with available data about maternal infection, 53 were classified as having symptomatic cCMV and were included in the study: 40 babies were born to mothers with primary infection and 13 babies were born to mothers with secondary infection. Analyzing data at birth, we found no statistical differences in the rate of clinical findings in the two groups, except for unilateral sensorineural hearing loss (SNHL) which was significantly more frequent in patients born to mother with secondary infection than in those born to mother with primary infection (46.2 vs. 17.5%, P = 0.037). During follow up, we found a higher rate of many sequelae (tetraparesis, epilepsy, motor and speech delay, and unilateral SNHL) in the group of children born to mothers with secondary infection, with a statistical difference for tetraparesis and unilateral SNHL. Otherwise, only children born to mothers with primary infection presented bilateral SNHL both at birth and follow up. Our data suggest that the risk of symptomatic cCMV and long-term sequelae is similar in children born to mother with primary and secondary CMV infection; it is important to pay appropriate attention to seropositive mothers in order to prevent reinfection and to detect and possibly treat infected babies

How future surgery will benefit from SARS-COV-2-related measures: a SPIGC survey conveying the perspective of Italian surgeons

COVID-19 negatively affected surgical activity, but the potential benefits resulting from adopted measures remain unclear. The aim of this study was to evaluate the change in surgical activity and potential benefit from COVID-19 measures in perspective of Italian surgeons on behalf of SPIGC. A nationwide online survey on surgical practice before, during, and after COVID-19 pandemic was conducted in March-April 2022 (NCT:05323851). Effects of COVID-19 hospital-related measures on surgical patients' management and personal professional development across surgical specialties were explored. Data on demographics, pre-operative/peri-operative/post-operative management, and professional development were collected. Outcomes were matched with the corresponding volume. Four hundred and seventy-three respondents were included in final analysis across 14 surgical specialties. Since SARS-CoV-2 pandemic, application of telematic consultations (4.1% vs. 21.6%; p < 0.0001) and diagnostic evaluations (16.4% vs. 42.2%; p < 0.0001) increased. Elective surgical activities significantly reduced and surgeons opted more frequently for conservative management with a possible indication for elective (26.3% vs. 35.7%; p < 0.0001) or urgent (20.4% vs. 38.5%; p < 0.0001) surgery. All new COVID-related measures are perceived to be maintained in the future. Surgeons' personal education online increased from 12.6% (pre-COVID) to 86.6% (post-COVID; p < 0.0001). Online educational activities are considered a beneficial effect from COVID pandemic (56.4%). COVID-19 had a great impact on surgical specialties, with significant reduction of operation volume. However, some forced changes turned out to be benefits. Isolation measures pushed the use of telemedicine and telemetric devices for outpatient practice and favored communication for educational purposes and surgeon-patient/family communication. From the Italian surgeons' perspective, COVID-related measures will continue to influence future surgical clinical practice

The role of immune suppression in COVID-19 hospitalization: clinical and epidemiological trends over three years of SARS-CoV-2 epidemic

Specific immune suppression types have been associated with a greater risk of severe COVID-19 disease and death. We analyzed data from patients >17 years that were hospitalized for COVID-19 at the “Fondazione IRCCS Ca′ Granda Ospedale Maggiore Policlinico” in Milan (Lombardy, Northern Italy). The study included 1727 SARS-CoV-2-positive patients (1,131 males, median age of 65 years) hospitalized between February 2020 and November 2022. Of these, 321 (18.6%, CI: 16.8–20.4%) had at least one condition defining immune suppression. Immune suppressed subjects were more likely to have other co-morbidities (80.4% vs. 69.8%, p < 0.001) and be vaccinated (37% vs. 12.7%, p < 0.001). We evaluated the contribution of immune suppression to hospitalization during the various stages of the epidemic and investigated whether immune suppression contributed to severe outcomes and death, also considering the vaccination status of the patients. The proportion of immune suppressed patients among all hospitalizations (initially stable at <20%) started to increase around December 2021, and remained high (30–50%). This change coincided with an increase in the proportions of older patients and patients with co-morbidities and with a decrease in the proportion of patients with severe outcomes. Vaccinated patients showed a lower proportion of severe outcomes; among non-vaccinated patients, severe outcomes were more common in immune suppressed individuals. Immune suppression was a significant predictor of severe outcomes, after adjusting for age, sex, co-morbidities, period of hospitalization, and vaccination status (OR: 1.64; 95% CI: 1.23–2.19), while vaccination was a protective factor (OR: 0.31; 95% IC: 0.20–0.47). However, after November 2021, differences in disease outcomes between vaccinated and non-vaccinated groups (for both immune suppressed and immune competent subjects) disappeared. Since December 2021, the spread of the less virulent Omicron variant and an overall higher level of induced and/or natural immunity likely contributed to the observed shift in hospitalized patient characteristics. Nonetheless, vaccination against SARS-CoV-2, likely in combination with naturally acquired immunity, effectively reduced severe outcomes in both immune competent (73.9% vs. 48.2%, p < 0.001) and immune suppressed (66.4% vs. 35.2%, p < 0.001) patients, confirming previous observations about the value of the vaccine in preventing serious disease

Reducing the environmental impact of surgery on a global scale: systematic review and co-prioritization with healthcare workers in 132 countries

Abstract Background Healthcare cannot achieve net-zero carbon without addressing operating theatres. The aim of this study was to prioritize feasible interventions to reduce the environmental impact of operating theatres. Methods This study adopted a four-phase Delphi consensus co-prioritization methodology. In phase 1, a systematic review of published interventions and global consultation of perioperative healthcare professionals were used to longlist interventions. In phase 2, iterative thematic analysis consolidated comparable interventions into a shortlist. In phase 3, the shortlist was co-prioritized based on patient and clinician views on acceptability, feasibility, and safety. In phase 4, ranked lists of interventions were presented by their relevance to high-income countries and low–middle-income countries. Results In phase 1, 43 interventions were identified, which had low uptake in practice according to 3042 professionals globally. In phase 2, a shortlist of 15 intervention domains was generated. In phase 3, interventions were deemed acceptable for more than 90 per cent of patients except for reducing general anaesthesia (84 per cent) and re-sterilization of ‘single-use’ consumables (86 per cent). In phase 4, the top three shortlisted interventions for high-income countries were: introducing recycling; reducing use of anaesthetic gases; and appropriate clinical waste processing. In phase 4, the top three shortlisted interventions for low–middle-income countries were: introducing reusable surgical devices; reducing use of consumables; and reducing the use of general anaesthesia. Conclusion This is a step toward environmentally sustainable operating environments with actionable interventions applicable to both high– and low–middle–income countries

An incidental finding of breast cancer after breast injury.

We report of a 52-year-old woman presenting with a breast palpable mass after a trauma due to accidental fall. The patient came to our attention to perform an ultrasonographic examination because of the persistence of the mass after the trauma. The exam showed an hypoanechoic oval formation with blurred margins and no vascularization at Power Doppler, located to the union of the upper quadrants of the right breast. The patient also performed mammographic examination, which showed an unknown oval radiopaque area. The findings were consistent with post-traumatic hematoma, even in relation to the anamnestic data, therefore we recommended anti-inflammatory therapy and a new check in fifteen days. The next ultrasonographic examination showed the persistence of the mass, slightly reduced in size, so we tried to achieve a more detailed diagnosis by performing MRI; however, the diagnostic doubt still remained, so we decided to perform a US-guided core-biopsy: the histological diagnosis was infiltrating ductal carcinoma of the breast. A review of the literature confirmed that breast lesions often are incidental findings after a breast trauma

Neuroendocrine lung cancer presenting as a breast lump

We report the case of a 54-year-old woman presenting to our attention for a palpable breast lump. The mammographic examination showed multiple round/oval areas of increased opacity spread on both breasts. The ultrasonographic examination showed multiple hypo-anechoic nodularities without retro-tumor acoustic shadowing. The mammo/ultrasonographic findings were worthy of histological analysis, thus we performed a ultrasound (US)-guided core-biopsy, obtaining a histological diagnosis of neuroendocrine carcinoma, probably originating from the lungs. The subsequent whole body CT scan, performed to search the primary neoplasm, put in evidence a neoplasm in the left lung, involving the pulmonary hilum, and infiltrating the bronchial branches. Moreover, there were multiple secondary lesions involving adrenal glands, brain and bowel. A review of the literature confirmed that breast lumps may be the first manifestation of a metastatic disease

Skin thickening as unique pathologic sign of an inflammatory breast cancer: a case report and review of the literature.

We report the case of a 42-year-old woman with inflammatory cancer of the right breast treated with neoadjuvant chemotherapy, surgery, additional chemotherapy, and consolidative radiotherapy (RT), that has metastatized to the chest wall and presented a resumption of disease on the contralateral breast. Magnetic Resonance (MR), performed after the second phase's fourth round of additional chemotherapy, showed a modest reduction of scar metastases on the right and a contralateral anomalous skin thickening with high signal intensity in T2 weighted images (WI) with multiple mass-like enhancements located in a wide area of the central region at the union of higher quadrants. These findings were suggestive for resumption of contralateral disease; the biopsy confirmed an inflammatory breast cancer (IBC) infiltrating lobular type with high mitotic rate. A retrospective evaluation of the previous MR exam, performed 5 months before, was conducted: on the left side only a modest skin thickening was found as an early sign. A careful review of the literature has confirmed that skin thickening, increased density and clinical signs of inflammation are the most common findings in inflammatory cancer. We report the case of a patient affected by IBC whose unique early sign of resumption on the contralateral breast was skin thickening

Lipofilling outcomes mimicking breast cancer recurrence. Case report and update of the literature

Breast [ipofilling uses autologous fat grqfling m correct breast defects afier radical m' conservative surgery. After early concern; regarding its application in reconstruction afire breast cancer (BC), in 2009 rhe American Society of Plastic Surgeons forrned a task force to assess the indications, safety and efficacy af autologous graft fat grafting. We report the case of a woman who came to our attention for a painful swelling off the left breast. She had undergone breast-comeruing therapy far BC, followed by Îipofilling. The breast ultrasound ( US) examinatian showed diffuse structural alteration and multiple ipohecoic areas with acoustic shadowing, mainly localized in the subcutaneaus tissue. Afier pharnacological treatment and short term follow-up US examination, considering the persistence of rhe clinical symptoms and structural alteration we performed contrast enhanced magnetic resonance imaging, thai showed multiple enhancing areas in the left breast. Suspecting local rumor recurrence, we carried out US-guided breast core—biopsy, whose histological examination documented liponecrosis. This observation raised a series of diagnostic and therapeutic issues highlighting the diagnostic pirfalls that the radiologist may encounter during the evaluation of patients who have undergone BC surgery and breast reconstruction through lipofilling

Breast MRI in Patients with Unilateral Bloody and Serous-Bloody Nipple Discharge: A Comparison with Galactography

Purpose. Assessing the role of breast MRI compared to galactography in patients with unilateral bloody or serous-bloody nipple discharge. Materials and Methods. Retrospective study including 53 unilateral discharge patients who performed galactography and MRI. We evaluated the capability of both techniques in identifying pathology and distinguishing between nonmalignant and malignant lesions. Lesions BIRADS 1/2 underwent follow-up, while the histological examination after surgery has been the gold standard to assess pathology in lesions BIRADS 3/4/5. The ROC analysis was used to test diagnostic MRI and galactography ability. Results. After surgery and follow-up, 8 patients had no disease (15%), 23 papilloma (43%), 11 papillomatosis (21%), 5 ductal cancer in situ (10%), and 6 papillary carcinoma (11%) diagnoses. Both techniques presented 100% specificity; MRI sensitivity was 98% versus 49% of galactography. Considering MRI, we found a statistical association between mass enhancement and papilloma (P<0.001; AUC 0.957; CI 0.888–1.025), ductal enhancement and papillomatosis (P<0.001; AUC 0.790; CI 0.623–0.958), segmental enhancement and ductal cancer in situ (P=0.007; AUC 0.750; CI 0.429–1.071), and linear enhancement and papillary cancer (P=0.011). Conclusions. MRI is a valid tool to detect ductal pathologies in patients with suspicious bloody or serous-bloody discharge showing higher sensitivity and specificity compared to galactography
