Abstract
Introduction
Taxane-based chemotherapy is one of the main cornerstones for treatment of metastatic
prostate cancer (mPCa). In aged and well-fit patients, an indication for taxane chemotherapy
should remain similar to the general population. Aiming to explore predictive factors
of fitness to taxane chemotherapy in older adult patients, a prospective observational
study was carried out in our institution.
Materials and methods
We collected data from a prospective mono-centric database of patients aged ≥70 years
old that were treated in our department. All patients underwent taxane treatment (either
docetaxel or cabazitaxel, the latter only in second line setting) starting with standard
treatment schedules (75 mg/m2 or 25 mg/m2 every three weeks, respectively). Data about G8 score post treatment decreases were
collected and reported. We explored associations between baseline age, G8 score, and
Charlson Comorbidity Index (CCI) with taxane dose reduction (DR), treatment temporary
suspension (TS), or definitive interruption (TDI). Logistic regression analysis was
performed to explore potential predictive factors for tolerability in patients treated
with docetaxel.
Results
One hundred-eighteen patients underwent taxane chemotherapy between 2011 and 2022,
the majority of cases in metastatic castrate resistant prostate cancer (mCRPC) setting
(85.6%). In the overall population, DR was performed in 40.7% of cases, and TS and
TDI were deemed necessary in 28% and 22.9% of patients, respectively. Forty-seven
percent of patients reported a significant deterioration in terms of G8 score (from
> to ≤14). Sixty-two percent of the overall population were deemed fit for further
treatment after taxane chemotherapy. Rate of DR, TS, and TDI was 29.4%, 11.8% and
9.2% in the docetaxel subgroup, vs 48%, 60% and 12% of patients treated with cabazitaxel,
respectively. Lower baseline G8 was reported as a continuous variable and the only
independent predictive factor for TDI in docetaxel subgroup (odds ratio [OR] 0.41,
95% confidence interval [CI] 0.25–0.68, p = 0.0008).
Discussion
Our data suggest that tolerability of taxane regimens in a pre-treated population
of older patients with prostate cancer is acceptable, despite a non-negligible rate
of TDI. Taxane chemotherapy should not be denied a priori in order to avoid undertreatment
of older adult patients.
