ABSTRACT Breast lymphography revealed linkage between the axillary and parasternal lymph nodes in three out of 55 patients with breast cancer. In all the cases the efferent lymph vessels outlined laterally and, according to Berg's scheme, lymph node groups I, II and III were filled. Lymph vessel responsible for the filling of the parasternal lymph nodes branched from the area of group I lymph nodes. In two out of the 3 cases axillary metastasis was detected in one case, however, the axillary was found unaffected. The lymph vessel linkage observed doesn't seem to support the widely accepted concept, according to which there are only direct efferent lymph vessels running from the breast to the parasternal lymph nodes. This finding also explains why the incidence of parasternal metastases in the breast is higher in the case of tumorous obstruction of the axillary lymph nodes.

    ABSTRACT: Axillary lymph node involvement is the best prognostic factor for breast cancer survival. Staging breast cancers by axillary dissection remains standard management and is part of the UK national guidelines for breast cancer treatment. In the presence of involved axillary lymph nodes best treatment has been shown to be axillary clearance (Fentiman and Mansell, 1991), but clearly for women whose nodes are uninvolved avoidance of morbidity is optimal and this will be achieved by minimal dissection of the axilla. Thus, for node-negative women the introduction of the sentinel node biopsy technique may revolutionise the approach to the axilla. These will be women with mammographic screen detected small well and moderately differentiated tumours (Hadjiloucas and Bundred, 2000). The impact of sentinel node biopsy in women who have symptomatic large tumours is unproven, and around half of these women will require a second procedure to clear their axilla or radiotherapy as treatment. Even for those women found to have involved sentinel lymph nodes the ability to use early systemic chemotherapy followed by axillary clearance or radiotherapy may provide long-term survival gains. Sentinel node biopsy should not, however, become routine practice until randomised controlled trials have proven its benefit and safety in reducing morbidity. Several randomised controlled trials (including ALMANAC) are currently underway.
