ABSTRACT

BACKGROUND: People with advanced breast cancer (ABC) in New Zealand (NZ) have a poorer five-year survival than their peers in other developed countries. Comparisons of ABC care in NZ with other countries suggest that NZ is sometimes out of line with international standards and that inequities exist within the NZ healthcare system. Our aim was to develop nationwide consensus guidelines for diagnosis and treatment of ABC that are uniquely suited for the NZ context and can be applied across the nation. We describe the process of creating, voting on, and disseminating the guidelines, and provide insight into how we can better optimize these processes for the NZ context in the future. METHODS: The ABC5 ESO-ESMO consensus guidelines were used and adapted to the NZ clinical context. A panel of breast cancer clinicians voted on these guidelines using the same model of membership representation as ABC5. OUTCOME: Overall consensus was equally high between ABC5 and ABC-NZ. Four NZ specific guidelines were introduced. The European-style panel discussion needs some adaptations for the NZ situation and a wider and more thorough consultation process, before voting begins, is preferred. The NZ Breast Special Interest Group has endorsed and agreed to take ownership of these and future guidelines and to facilitate the next iteration of the ABC-NZ guidelines meeting. CONCLUSIONS: The process was successful in creating the guidelines but can be improved in future meetings to streamline the process of creating and updating guidelines in the manner most suited to the NZ context and audience.

ABSTRACT

Breast lymphomas are rare and consensus about their treatment is lacking. A population-based study of 38 breast lymphomas, registered in the databases of two Comprehensive Dutch Cancer Centers from 1981 to 1999, was performed. The median age of all female patients was 65 years (20-92): 25 patients had localized and 13 patients had disseminated lymphoma. The most common type was diffuse large B-cell lymphoma (DLBCL), which accounted for 17 of the localized and 4 of the disseminated cases. Burkitt's lymphoma (BL), three being disseminated, was found in four patients. There were six extranodal marginal zone lymphomas (ENMZL), three being localized. Seven DLBCL and one BL showed additional histological features of mucosa-associated lymphoid tissue (MALT) lymphoma. Localized aggressive lymphomas treated with surgery and/or radiation therapy had relapse rates of 100% and 67%, respectively. Cyclophosphamide, hydroxydaunomycin, vincristine, and prednisone (CHOP)-like chemotherapy with or without local irradiation led to 17% relapses in patients with localized aggressive lymphoma. Median follow-up time was 32 months (0.6-218); 37% of the patients relapsed and 24% had progressive disease. Response to salvage regimens, given to 91% of the patients with recurrent disease, was poor. The 2-year overall survival rate was 63%, 72% for patients with localized disease, and 46% for patients with disseminated lymphoma. The majority of breast lymphomas are localized aggressive lymphomas that should be treated initially with CHOP-like chemotherapy with or without irradiation. The initial choice of treatment is very important because response to salvage regimens is poor.
