Summary
POSNOC (POsitive Sentinel NOde – adjuvant therapy alone versus adjuvant therapy plus Clearance or axillary radiotherapy) will address the key unresolved challenge in breast cancer surgery. A controversial US trial, ACOSOG Z0011, indicates that many breast cancer patients with limited disease in the sentinel node can safely avoid further nodal surgery. This would be a major advance, but there is widespread doubt that the results are broadly applicable. POSNOC will clarify this key issue.

Summary
Lymph gland screening with isotopes (Lymphoscintigraphy) has revealed unexpected pathways of cancer spread. This study, using an X-ray injection technique in human cadavers, is re-evaluating the outdated Melways Roadmap of lymph vessel pathways. The aims are to give accurate predictions of cancer spread, explain unusual clinical manifestations and to provide a new method of treating lymphoedema, the incapacitating swelling of limbs that may complicate lymph gland surgery or radiotherapy.
