An “all-season” mammoplasty

A reduction mammoplasty must produce a reduction in volume, a natural lasting shape, and minimal residual scarring. Many attempts to achieve this goal have been developed in recent years. The author described, in 1970, a vertical technique achieving an important reduction and a good shape but with the appearance of the end of the vertical scar below the brassiere line. In 1977, the author [3] modified the technique by the adjunction of a small horizontal scar to eliminate the inconvenience of the visible part of the vertical scar. In this article the author describes his technique which appears to be suitable for most types of breast deformities.     

乳腺髓样癌的超声检查与组织病理的相关性分析

目的:探讨超声检查在诊断乳腺典型髓样癌中的临床意义。方法:按严格的病理诊断学标准将病例重新分类为乳腺典型髓样癌和非典型髓样癌,比较两者间声像学特征的异同。结果:32例中有13侧重新诊断为乳腺典型髓样癌;另外19例为非典型髓样癌。13例典型髓样癌患者中的10例边界整齐光滑;全部19例非典型髓样癌病人没有一例边界光滑,或者边界呈锯齿状(16例),或者边界光滑伴局部不规则(3例)。非典型与典型髓样癌间肿瘤边界的规则性有明显的差异。结论:如果超声检查提示肿瘤边界呈锯齿状或肿瘤边界光滑伴局部不规则,应行整个肿瘤的病理评估防止典型髓样癌的过诊断。     

SARS-CoV-2 neutralizing antibodies after first vaccination dose in breast cancer patients receiving CDK4/6 inhibitors

Undoubtedly, the development of COVID-19 vaccines displays a critical step towards ending this devastating pandemic, considering their protective benefits in the general population. Yet, data regarding their efficacy and safety in cancer patients are limited. Herein we provide the initial analysis of immune responses after the first dose of vaccination in 21 breast cancer patients receiving cyclin-dependent kinase 4 and 6 (CDK4/6) inhibitors. The levels of neutralizing antibodies post vaccination were similar to the matched healthy controls, whereas no safety issues have been raised. Further exploration is needed to reduce the uncertainty of SARS-CoV-2 immunity among cancer patients under treatment.     

Contralateral prophylactic mastectomy: A narrative review of the evidence and acceptability

The uptake of contralateral prophylactic mastectomy (CPM) has increased steadily over the last twenty years in women of all age groups and breast cancer stages. Since contralateral breast cancer is relatively rare and the breast cancer guidelines only recommend CPM in a small subset of patients with breast cancer, the drivers of this trend are unknown. This review aims to evaluate the evidence for and acceptability of CPM, data on patient rationales for choosing CPM, and some of the factors that might impact patient preferences. Based on the evidence, future recommendations will be provided. First, data on contralateral breast cancer risk and CPM rates and trends are addressed. After that, the evidence is structured around four main patient rationales for CPM formulated as questions that patients might ask their surgeon: Will CPM reduce mortality risk? Will CPM reduce the risk of contralateral breast cancer? Can I avoid future screening with CPM? Will I have better breast symmetry after CPM? Also, three different guidelines regarding CPM will be reviewed. Studies indicate a large gap between patient preferences for radical risk reduction with CPM and the current approaches recommended by important guidelines. We suggest a strategy including shared decision-making to enhance surgeons’ communication with patients about contralateral breast cancer and treatment options, to empower patients in order to optimize the use of CPM incorporating accurate risk assessment and individual patient preferences.     

动态增强磁共振成像在评估女性乳房乳头乳晕血供的应用

目的探究动态增强磁共振成像(DCE-MRI)用于评估女性乳房乳头乳晕血供特点的可行性,为乳房整形手术提供乳头乳晕的血供参考。方法从2012年3月至2019年10月华中科技大学同济医学院附属同济医院影像数据库中收集女性乳腺DCE-MRI图像资料,选择未发现肿物的正常乳房的DCE-MRI图像进行研究。在西门子工作站将患者乳腺DCE-MRI图像通过图像减影获取乳房血管图像,分别对轴位、冠状位和矢状位的最大密度投影(MIP)图像进行评估,结合三维MIP图像识别所有供应乳头乳晕的血管。乳头乳晕的血供被划分为内上、内侧、内下、外上、外侧、外下、中央、上方和下方9个象限,对各个象限血管进行统计和分析,并测量血管至乳房皮肤表面投影的最大距离。采用SPSS 19.0软件进行统计分析,通过卡方检验分别比较左侧与右侧乳房的乳头乳晕复合体(NAC)血供象限分布构成比。计算血管到皮肤距离的平均值、标准差及95%置信区间,通过方差分析比较各象限血管至皮肤距离的差异。P<0.05为差异具有统计学意义。结果共收集到245例患者490只女性乳房DCE-MRI图像,其中97例患者97只乳房发现有乳腺肿物,其余393只为正常乳房(97例单侧乳房、148例双侧乳房),将其作为研究对象。患者年龄23~72岁,平均43.7岁。393只乳房(左侧200只、右侧193只)共发现有637条(左侧311条、右侧326条)乳头乳晕供应血管。在637条血管中,内上象限269条(42.2%),外上180条 (28.3%),内侧57条(8.9%),下方37条(5.8%),中央30条(4.7%),内下25条(3.9%),外下25条(3.9%),上方11条(1.7%),外侧3条(0.5%)。卡方检验表明左侧乳房和右侧乳房在NAC血供象限分布构成比差异无统计学意义(χ2 =6.4,P=0.602)。除中央象限血管以外,所有血管到皮肤表面投影最大距离的平均值为0.91 cm, 95%置信区间为0.86~0.96 cm。方差分析表明各象限供血血管到皮肤投影的最大距离,差异有统计学意义(F=11.4,P<0.001)。结论 DCE-MRI可以清晰地显示乳头乳晕的血供来源。乳头乳晕血供主要来源于内上象限和外上象限的血管,血管在皮下约1 cm深度走行。     

Protroca: A Noninterventional Study on Prophylactic Lipegfilgrastim against Chemotherapy-Induced Neutropenia in Nonselected Breast Cancer Patients

BackgroundProtroca evaluated the efficacy and safety of primary and secondary prophylaxis of neutropenia with lipegfilgrastim (Lonquex®) in breast cancer patients receiving neoadjuvant or adjuvant chemotherapy (CT).Patients and MethodsOf the 255 patients enrolled, 248 patients were evaluable for the intent-to-treat (ITT) and 194 patients for the per-protocol set. Primary and secondary end points after lipegfilgrastim treatment were assessed.ResultsNine patients of the ITT set receiving lipegfilgrastim as primary prophylaxis (n = 222) had febrile neutropenia of grade 3–4 (5 patients) or infection of grade 3–4 (4 patients); 1/26 of those receiving secondary prophylaxis had an event. Dose reductions were performed in 9.5% of the patients. Postponement of cancer CT cycles for >3 days occurred in <15% of patients; 10.8% (92/851 AEs) and 8% (2/25 SAEs) of documented adverse events and serious adverse events, respectively, were related to lipegfilgrastim.ConclusionsApplication of lipegfilgrastim was effective as primary and secondary prophylaxis in the prevention of CT-induced neutropenia in breast cancer.     

Successful salvage of an infected breast prothesis by changing from continuous to intermittent suction under continuous irrigation

IntroductionImplant-based breast reconstruction is a widely performed procedure. However, prostheses are susceptible to infection and there are currently no established guidelines on treatment. In the present case, a prosthesis was salvaged by changing from continuous irrigation and suction to continuous irrigation and intermittent suction. This case report has been reported in line with the SCARE criteria [1].Presentation of caseA 50-year-old female patient underwent implant-based breast reconstruction following surgery for breast cancer. One month later, the left breast prosthesis was infected with abscesses. Surgical treatment and continuous irrigation were performed as postoperative therapy. However, recurrent infection was detected a few days after surgery. Continuous irrigation was changed to continuous irrigation with intermittent aspiration, which successfully controlled the infection.DiscussionFactors that limit the effectiveness of continuous irrigation and aspiration have not yet been identified. Inflow/discharge shunt routes may be established in continuous aspiration, and, thus, sufficient cleaning may not be possible. On the other hand, the storage of water throughout the wound in intermittent aspiration may facilitate cleaning.ConclusionIntermittent suction worked well in this patient and, thus, warrants further study.
