Comparison between invasive breast cancer with extensive peritumoral vascular invasion and inflammatory breast carcinoma: a clinicopathologic study of 161 cases.
Objectives: Extensive peritumoral neoplastic lymphovascular invasion (ePVI) is a marker of aggressiveness in invasive breast carcinoma (BC). Methods: We explored the impact of ePVI on different BC subtypes. In a total of 2,116 BCs, 91 ePVI-BCs, 70 inflammatory breast carcinomas (IBCs), and 114 casual BCs as a control group (CG-BC) were recruited. Results: Patients affected by ePVI-BC were younger, had larger tumors, higher histologic grade, elevated Ki-67 score, Her2/neu overexpressed, and more lymph node metastases compared with CG-BC ( P < .001). Interestingly, only younger mean age at diagnosis differentiated patients with ePVI-BC from patients affected by IBC. ePVI-BC showed a clinical outcome intermediate between the prognoses of IBC and CG-BC. Conclusions: Results suggest that ePVI-BC and IBC may share some pathologic processes, providing a novel perspective on the heterogeneity of BC. Epidemiologic data and molecular studies on gene expression features are needed to rationally classify these tumors into their identified subtypes
Laser microsurgery versus radiotherapy versus open partial laryngectomy for T2 laryngeal carcinoma: a systematic review of oncological outcomes
The aim of the current systematic review is to update the pooled survival outcome of patients with T2 glottic carcinoma treated with either laser surgery (CO2 transoral laser microsurgery [CO2 TOLMS]), radiotherapy (RT), or open partial laryngectomy (OPL)
Influence of different lipid emulsions on specific immune cell functions in head and neck cancer patients receiving supplemental parenteral nutrition: An exploratory analysis.
Abstract Objectives The effect of diet on immune responses is an area of intense investigation. Dietary lipids have been shown to differently influence and fine-tune the reactivity of immune cell subsets, thus potentially affecting clinical outcomes. Patients with head and neck squamous cell carcinoma face malnutrition, due to swallowing impairment related to the tumor site or to treatment sequalae, and may need supplemental parenteral nutrition (SPN) in addition to oral feeding when enteral nutrition is not feasible. Additionally, immune depression is a well-known complication in these patients. Parenteral nutrition (PN) bags contain amino acids, minerals, electrolytes and mostly lipids that provide calories in a concentrated form and are enriched with essential fatty acids. The aim of this study was to investigate multiple parameters of the immune responses in a cohort of patients with head and neck squamous cell carcinoma undergoing supplemental PN with bags enriched in ω-3 or ω-9 and ω-6 fatty acids. Methods To our knowledge, this was the first exploratory study to investigate the effects of two different PN lipid emulsions on specific immune cells function of patients with advanced head and neck squamous carcinoma. ω-3-enriched fish-oil-based- and ω-6- and ω-9-enriched olive-oil-basedSPN was administered to two groups of patients for 1 wk in the context of an observational multicentric study. Polychromatic flow cytometry was used to investigate multiple subsets of leukocytes, with a special focus on cellular populations endowed with antitumor activity. Results Patients treated with olive-oil-based PN showed an increase in the function of the innate (natural killer cells and monocytes) and adaptive (both CD4 and CD8 cells) arms of the immune response. Conclusion An increase in the function of the innate and adaptive arms of the immune response may favor antitumoral responses

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
Breast cancer and gastrointestinal metastasis. A case report and review of the literature
Introduction: Invasive lobular cancer (ILC) is the second most common type of a heterogeneous group of different histological types of invasive breast carcinoma. Breast cancer can metastatize anywhere, the most common sites are bones, liver, lungs and brain. Gastrointestinal tract (GI) metastases observed in autopsy studies account for about 6% to 18% of the overall metastases from breast cancer. Objective: We describe a 54-year old woman with recurrent ILC in the contralateral breast. She underwent right mastectomy 16 years before. After symptomatic presentation a duodenal invasion was found and subjected to diagnostic scrutiny (FDG PET/CT, diagnostic CT, MR, EGDS). In particular, we analyse if FDG PET/CT is enough accurate in the restaging of the patient. A review of our database and of the literature of similar cases were made. Results: In this patient CT and RM were suspicious for a slow developing process of the duodenum but FDG PET/CT did not show pathological uptake in the affected duodenal tract. A highly intense focus was described in a cervical lymph node, that there isn't metastatic lesion, whereas the recurrent breast lesion had only slight increased glycolytic activity. CONCLUSION: Metastatic lobular carcinoma of the breast is a rare entity with a heterogeneous range of clinical presentations. Detection of eventual gastrointestinal metastases are complicated to assess. ILC has various scale of glycolytic activity both in the primary lesion as well in the metastatic foci. When the level of suspicion is high and there is no uptake of FDG, further investigations are necessary
Breast cancer and neoadjuvant chemotherapy: indications for and limits of breast-conserving surgery
AIM: The aim of our study was to determine how many and what subtypes of breast cancer could be treated with breast-conserving surgery after NACT. Another outcome was to determine the applicability of MD Anderson Cancer Center nomogram to predict it. MATERIAL OF STUDY: We reviewed the histological examinations of 86 performed mastectomies according to the indications to BCS after NACT. For 73 cases, collected all the necessary data, we could use the nomogram available on the MDACC website to calculate the probability of BCS and pCR. RESULTS: In our experience the BCS rate would increase by 34,1%, from 3,7% to 3.,8%. Patients with Triple Negative and HER2+, ER- more than ER+, show higher rates of pCR and BCS. The MDACC nomogram predicts accurately the probability of pCR and BCS after NACT in HER2 negative cancers but not in HER2 positive ones treated with Trastuzumab. This suggests that a specific nomogram for HER2 positive carcinomas has to be developed. CONCLUSION: BCS after NACT is feasible and safe in terms of LRR, DFS and OS, if patients are properly studied and selected. Indication to BCS after NACT needs of a multidisciplinary assessment considering clinical staging, biological characteristics, the radiological response pattern and the expected concordance between imaging and histology
Male Breast Cancer: Surgical and Genetic Features and a Multidisciplinary Management Strategy
Background: Male breast cancer (MBC) is a rare disease with a rising incidence trend. The major risk factors related to MBC are a positive family history of breast cancer (BC) and BRCA1/2 mutations, which indicate a relevant genetic role. Methods: In this retrospective series, we enrolled 69 male patients presenting with male breast cancer (MBC) between 01/01/1992 and 31/12/2018, and 26 high-risk not-affected men presenting between 01/01/2016 and 31/12/2018. Participants' electronic clinical records were reviewed. Patients' data reported age at diagnosis, tumor characteristics, therapeutic management, and BRCA1/2 status as well as a family history of breast, ovarian, or prostate cancer (PCa) in first-degree relatives. Results: We analyzed 69 MBC patients. Median age was 64 years. The majority of tumors diagnosed were of an early TNM stage. The most frequent histological subtype was invasive ductal carcinoma (76.7%). Hormone receptors were positive in >90% of MBC cases. Nearly all patients underwent modified radical mastectomy or total mastectomy. Adjuvant endocrine therapy was delivered in 59.4%. Among MBC-affected patients, we recorded a high percentage of a positive family history of BC. Mutational analysis for the BRCA1/2 genes was performed in 17 MBC patients; 11.8% were carriers of BRCA2 pathogenic mutations. Among 26 healthy high-risk subjects included in this case series, 4 were BRCA1 mutation carriers and 9 were BRCA2 mutation carriers. Discussion: We evaluated the distribution of clinicopathological characteristics in MBC subjects and assessed the frequency of mutations in the BRCA genes in affected patients and healthy high-risk subjects, with the aim of proposing a surveillance program for BC and PCa
