Fundamental steps
• Task Force (TF) on Use of Taxanes in Older Breast
Cancer Patients
• First meeting: 26th October in Copenhagen, during the
SIOG 2013 Annual Conference
• Several drafts…..(thanks to Rob Stepney, medical writer)
• Last draft circulated to all the members of the TF on
September 2014… document still to be finalized

Rationale & aims
• Taxanes are key agents in the treatment of breast
cancer both in the neo/adjuvant and metastatic setting
• Review available data on the use of docetaxel, paclitaxel
and nab-paclitaxel in elderly breast cancer patients
• Expert recommendations (position paper)

� There is no significant data to support dose modification of docetaxel and paclitaxel based on age alone

Taxanes in early breast cancer
• In sequence with anthracyclines in the
neo/adjuvant setting ie. (F)AC->T
• In anthracycline-free regimens in low-risk
patients ie. TC
F, 5-fluorouracil; A, anthracycline; T, taxane; TC, docetaxel plus cyclophosphamyde

Age groups (< 60, 60 to 64, 64+)
• Higher rates of dose delays and reductions, hospitalization,
therapy discontinuation, hematological toxicity, and some non-
hematological toxicities (ie, loss of appetite, severe fatigue,
and mucositis)
• The incidence of treatment-related deaths increased
linearly with advancing patient age (P.0022)

Focusing on elderly patients…
Adapted from Biganzoli et al. Crit Rev Oncol Hematol 2009
Weekly docetaxel and paclitaxel in elderly patients: safety data
• Efficay was age indepedent
• Grade ≥3 leucopenia,granulocytopenia, anorexia, bilirubin elevation and
neurotoxicity increased linearly with age
• Patients over 65 years receiving second-line therapy had the shortest time to
neurotoxicity (35% at 6 cycles)Ann Oncol 2011

Nab-paclitaxel
• Solvent-free paclitaxel; no need for premedication; at
least as effective as standard taxanes

• In the adjuvant setting taxanes are associated with
increased toxicity compared with younger women, but
can be added to anthracyclines in high-risk healthy
elderly patients, or replace anthracyclines to reduce the
cardiac risk (SIOG and Eusoma Recommendations1)
• In HER-2 positive patients, the combination of docetaxel
plus cyclophosphamide offers an alternative to
anthracycline-taxane based chemotherapy and reduces
the risk of trastuzumab-related cardiac toxicity

• Weekly taxanes are a reasonable option for the treatment of older patients with advanced breast cancer
• Close monitoring of side effects is recommended since fatigue (docetaxel) and neurotoxicity (paclitaxel) might have a negative impact on function
• Nab-paclitaxel represents a potential alternative to standard taxanes due to a favorable safety profile (when
the 100-125 mg/m2 weekly dose-schedule is used) and shorter time to resolution of sensory neuropathy to a lesser grade without the the need for steroid premedication
• Studies are ongoing to define the role of nab paclitaxel in older patients

• Interim safety analysis after 207 patients completed treatment
• Treatment A better tolerated than nab-paclitaxel plus capecitabine

• More G 3-4 non-hematological AEs in arm B (59% vs 19%)
• At 48 months, rates of invasive disease-free survival equivalent between the
treatments(hazard ratio [HR] 0.98, [P = .9597])
Age ≥ 65 yearsStage pT3/4 or pN2/3 or stage pT1/2 and pN0/1 (0-3 involved lymph nodes) with an increased risk according to the clinico-pathological or uPA/PAI-1 criteria
nab-Paclitaxel 100 mg/m2 on days 1, 8, 15 q22 with a week of rest every 6 weeks in combination with
capecitabine 2000 mg/m2, days 1 - 14 orally, divided into 2 daily doses every 3 weeks for 6 cycles
