“…The exact frequency and risk of this recurrence is difficult to assess, and reflects the composition of the case series, with higher rates of theoretical ‘miss’ associated with higher nodal disease burden, stage IV disease, and possibly lower rates of current standard chemotherapy. In both papers by Chang et al ., which only examined recurrent lesions, the rate of SCF LN metastases outside the ESTRO/RTOG CTV was lower than in the other two series, which also included patients who presented with SCF metastases at diagnosis . However, taken together, these studies suggest that the posterior volume, which extends beyond the scalene muscles, is at risk from metastatic breast cancer.…”

“…There is a greater risk of recurrence if microscopic disease is inadequately treated, but the risk of acute and late toxicity increases if excessive normal tissue is included in the field . Several international studies have been published recently reporting failure patterns of the commonly utilised breast contouring guidelines . These are timely to inform debate.…”

Contouring consensus guidelines in breast cancer radiotherapy: Comparison and systematic review of patterns of failure

Summary Adequate coverage of sites harbouring potential microscopic disease is paramount, where the clinical decision has been made to include regional lymph node radiotherapy for patients with breast cancer. This must be achieved in balance with minimising dose to normal tissues. Several international consensus guidelines detailing clinical target volumes (CTVs) are available, but there is currently no agreement as to which is most appropriate for a given clinical situation. Contouring guidelines are beneficial for routine practice and essential for clinical trial quality assurance. The aims of this study were as follows: to provide a single point of comparison of four commonly used contouring guidelines, including one used in a current Trans‐Tasman Radiation Oncology Group trial; and to undertake a systematic review of existing studies which map sites of breast cancer recurrence against contouring guidelines. Two international consensus guidelines (European Society for Radiotherapy and Oncology, and Radiation Therapy Oncology Group) were compared with two clinical trial guidelines (TROG 12.02 PET LABRADOR and the Proton/Photon trial NCT02603341 RADCOMP). Comprehensive literature search for patterns of failure studies was undertaken using Embase and Pubmed. We detail the small but significant differences between the breast consensus guidelines, particularly the supraclavicular (SCF) and internal mammary chain CTVs. Seven series were found mapping recurrence patterns. These results are discussed in the context of the contouring guidelines. Several studies found the SCF CTV is the area at greatest risk of geographical ‘miss’. This review will facilitate further discussion about guideline selection and modification, particularly for future clinical trials in Australia and New Zealand.

Breast cancer is one of the most common malignancies in women. It frequently metastasizes to the lungs, liver, and bone. Breast cancer metastasis to skeletal muscles is rare. Chest wall recurrence in patients that have undergone mastectomy is the most frequent form of local recurrence, and it is generally accompanied by nodules or masses on the chest wall. Here, we describe a case of the unusual appearance of invasive lobular cancer metastasis to the pectoral muscles without discrete nodules or masses in a patient who had undergone mastectomy 12 years ago.
