The surgical management of male breast cancer: Time for an easy access national reporting database?

Introduction Male breast cancer is extremely rare with an incidence of less than 1% of all breast cancers. Literature reports a peak of incidence at roughly 71 years of age. Management currently follows the same clinical pathways as female breast cancer as a general rule. Methods A retrospective search for all patients who were referred and diagnosed with male breast cancer at our centre was undertaken. Patients notes were then explored for demographics, histological staging, multidisciplinary team meeting outcome and treatment. A literature search including the search terms ‘Male Breast Cancer AND Surgery’ or ‘Male Breast Cancer AND Experience’ were used. Non English language articles, or those without abstracts were excluded. Results Seven patients were reviewed over 3 years (2006–2009). Mean agea was 69 years and mean lesion size was 15 mm. Histology was invasive ductal carcinoma for all patients. All patients were ER receptor positive. Two patients were HER2 positive. Five patients were offered mastectomy. One patient refused treatment. In follow up at 36 months there were 3 recurrences. 1 patient was lost to follow up. There were 3 mortalities. The literature search identified 72 articles. Articles were subdivided into those that discussed the surgical management of male breast cancer (n = 8), articles that discussed male breast cancer as podium presentations or posters with no full text article publication (n = 13) and finally full text publications of case experience of male breast cancer (n = 21). Discussion We report a series of seven cases of male breast cancer encountered over three years, evaluating patient demographics as well as treatment and outcomes. In our series patients were managed with mastectomy. New evidence is questioning the role of mastectomy against breast conserving surgery in male patients. Furthermore there is a lack of reporting infrastructure for national data capture of the benefits of surgical modalities. Literature review highlights the varied clinical experience between units that remains reported as podium presentation but not published. The establishment of an online international reporting registry would allow for efficient analysis of surgical outcomes to improve patient care from smaller single centres. This would facilitate large scale meta analysis by larger academic surgical centres

Flow cytometric analysis of cellular changes in mice after intradermal inoculation with a liposome-iscom adjuvanted vaccine

As it is not known what changes to leucocyte homeostasis are mandatory for effective adjuvant action, the biological relevance of systemic changes elicited by different vaccine formulations can only be interpreted in the context of the immunological outcomes. We used flow cytometry to quantify the changes in leucocyte subsets induced in mice intradermally immunized with SAMA4 (adjuvant group), outer membrane proteins (OMP) purified from Actinobacillus pleuropneumoniae (OMP antigen group), SAMA4 adjuvanted OMP (OMP vaccine group), or phosphate-buffered saline (PBS: control group). This approach allowed direct comparisons to be made between the effects of antigen, adjuvant or antigen-adjuvant complexes on immune effector cell populations. Antigens complexed with the liposome-iscom hybrid adjuvant, SAMA4, generated strong antibody responses and cytotoxic T-cell activity in animals immunized intradermally, reflecting remobilization and recruitment of specific cell populations. Splenomegaly, due to granulocytosis, monocytosis and megakaryocytosis, was most prominent in the OMP vaccine group. Histological examination of spleen sections confirmed that these changes were due primarily to splenic haematopoiesis. Circulating numbers of granulocytes and monocytes increased significantly (
