Adjuvant chemotherapy in older breast cancer patients: How to decide?

(6% vs. b 1%), dyspnea (4% vs. 1%), hyperglycemia (4% vs. b 1%), fatigue (4% vs. 1%), and pneumonitis (3% vs. 0%). In TAMRAD the main toxicities associated with tamoxifen plus everolimus were fatigue (72% vs. 53% with tamoxifen alone), stomatitis (56% vs. 7%, grades 34 11% vs. 0%), rash (44% vs. 7%), anorexia (43% vs. 18%), and diarrhea (39% vs. 11%). Conclusions: The reported efcacy data are extremely interesting but safety concerns are clearly present. Toxic effects can inuence the practical use of, and compliance with, this class of drugs, especially in an elderly patient population where compliance with oral agents, even with favourable safety proles, is lower than in the general population. EUSOMA and SIOG recommendations for the management of elderly patients with breast cancer clearly state that there is a delicate balance between overtreatment and undertreatment of advanced disease, in which maintenance of quality of life (QoL) is a priority.

While research is focused in identifying subgroups of patients who derive the greatest benet from these ET + everolimus combinations, it is essential that clinicians are educated about key recommenda- tions for toxicity management and specic guideline for dose modications.

Department of General Medical Oncology, University Hospitals Leuven, Belgium Adjuvant chemotherapy can decrease the risk of metastases signi- cantly in early breast cancer, but the optimal selection of patients remains a major challenge. A sizeable proportion of elderly with operable breast cancer dies of non-cancer related causes, but about 40% of patients 80y or older still die due to breast cancer. The benet of adjuvant chemotherapy should rst be driven by biological subtype: Luminal A tumors derive little benet from adjuvant chemotherapy even in younger women, so in older individuals with competing causes of death, it is generally not acceptable to administer adjuvant chemotherapy, even in more extended tumors. Luminal B tumors are the most difcult area in the general population for adjuvant chemotherapy decisions. The benet of adjuvant chemotherapy in the older population is expected to be less than in the younger population, so luminal B tumors probably don't require adjuvant chemotherapy in the majority of older cancer patients, although we are waiting the results from the recently started ASTER trial including gene expression data. In contrast, triple negative and HER2+ breast tumors generally require adjuvant chemotherapy in the general population, and this is probably the setting where most benet can be achieved in older cancer patients. The extent of the disease (tumor size and nodal status) can further help in the decision. But patient characteristics are much more important in older individuals than in younger women. Biological age, assessed by geriatric assessment can help in estimating the life expectancy and ability to tolerate and cope with side effects, and is a better decision tool than chronological age by itself. Last but not least, patient preference is of utmost importance, since different elderly might have different expectations and wishes. The choice of chemotherapy remains a difcult item. In theory, identical regimens can be used in older and younger women, but there is clear evidence that toxicity and toxic mortality increases with age, while dose reductions might decrease efcacy. AC/CMF has been shown to be superior to capecitabine, while anthracyclines are generally preferred above CMF. Taxanes can be added, or replace anthracyclines. Recent data suggest that 4 cycles of chemotherapy could be sufcient. doi:10.1016/j.jgo.2012.10.142 Melanoma F9 Epidemiology of melanoma in older patients 1 M.L.G. Janssen-Heijnen. Department of Clinical Epidemiology, VieCuri Medical Centre, Venlo, The Netherlands Purpose of the study: Giving insight into the epidemiology of melanoma in older patients. Methods: Besides evidence from peer-reviewed publications, popu- lation-based data from the Netherlands Cancer Registry and the Eindhoven Cancer Registry were used for giving insight into the age distribution of melanoma, the trends in incidence and survival, stage, histological subtype, the prevalence of co-morbidity, treatment and quality-of-life after treatment. Results: Elderly have an increase in incidence and mortality rates of melanoma that are up to 10-fold higher compared to younger patients. In addition, there is a more rapid increase in incidence among older males than older females, which has led to a reverse malefemale ratio among elderly. An increase in incidence of thick melanomas (N 4.0 mm) is also seen, but only among elderly males. Elderly melanoma patients have poorer survival compared to younger patients. The question is whether age itself is an indepen- dent prognostic factor or whether the poorer prognosis can be explained by the fact that factors for poor prognosis are more prevalent among older patients with melanoma (higher proportion of males, more late diagnosis, a weaker immune system, more nodular histology, more serious co-morbidity and decreased organ functions). In addition, treatment of melanoma in elderly is complex. Since elderly are often excluded from clinical trials, few data exist on the efcacy and safety of treatment of elderly with melanoma. Conclusions: Currently, early detection is the best chance of inuencing behaviour of melanoma in the elderly. Since there was a more rapid increase in incidence of melanoma among males, and an increase in thick melanomas was only seen among elderly males, future screening campaigns should especially focus on older men. Since prognosis is poorer among elderly and elderly are often excluded from clinical trials, safety and effects of (new) treatments need to be investigated in elderly, with a special emphasis on the inuence of treatment on changes in quality-of-life. doi:10.1016/j.jgo.2012.10.143 1 Not all the biographies were available at time of printing. 1 Not all the biographies were available at time of printing. 1 Not all the biographies were available at time of printing.

Adjuvant chemotherapy can decrease the risk of metastases signifi-cantly in early breast cancer, but the optimal selection of patientsremains a major challenge. A sizeable proportion of elderly withoperable breast cancer dies of non-cancer related causes, but about40% of patients 80y or older still die due to breast cancer. The benefit ofadjuvant chemotherapy should first be driven by biological subtype:Luminal A tumors derive little benefit from adjuvant chemotherapyeven in younger women, so in older individuals with competingcauses of death, it is generally not acceptable to administer adjuvantchemotherapy, even in more extended tumors. Luminal B tumors arethe most difficult area in the general population for adjuvantchemotherapy decisions. The benefit of adjuvant chemotherapy inthe older population is expected to be less than in the youngerpopulation, so luminal B tumors probably don't require adjuvantchemotherapy in the majority of older cancer patients, although weare waiting the results from the recently started ASTER trial includinggene expression data. In contrast, triple negative and HER2+ breasttumors generally require adjuvant chemotherapy in the generalpopulation, and this is probably the setting where most benefit canbe achieved in older cancer patients. The extent of the disease (tumor

Purpose of the study: Giving insight into the epidemiology ofmelanoma in older patients.Methods: Besides evidence from peer-reviewed publications, popu-lation-based data from the Netherlands Cancer Registry and theEindhoven Cancer Registry were used for giving insight into the agedistribution of melanoma, the trends in incidence and survival, stage,histological subtype, the prevalence of co-morbidity, treatment andquality-of-life after treatment.Results: Elderly have an increase in incidence and mortality rates ofmelanoma that are up to 10-fold higher compared to youngerpatients. In addition, there is a more rapid increase in incidenceamong older males than older females, which has led to a reversemale–female ratio among elderly. An increase in incidence of thickmelanomas (N4.0 mm) is also seen, but only among elderly males.Elderly melanoma patients have poorer survival compared toyounger patients. The question is whether age itself is an indepen-dent prognostic factor or whether the poorer prognosis can beexplained by the fact that factors for poor prognosis are moreprevalent among older patients with melanoma (higher proportionof males, more late diagnosis, a weaker immune system, morenodular histology, more serious co-morbidity and decreased organfunctions).
