Predictive fActors for toleraNce to Taxane Based CHemotherapy In Older adultS Affected by mEtastatic Prostate Cancer

Study Overview
=================
Brief Summary
-----------------
Aiming to explore predictive factors of fitness to taxane chemotherapy in elderly patients, the investigators collected data from a prospective mono-centric database of patients aged >/= 70 years old treated in our department, and explored association between baseline age, G8 score and Charlson comorbidity index with taxane dose reduction, treatment temporary suspension or definitive interruption.

Detailed Description
-----------------
Patients included in the analysis were affected by metastatic prostate cancer with >/=70 years old. All patients underwent Taxane treatment starting with standard treatment schedules (75 mg/m2 or 25 mg/m2 every 3 weeks, respectively). Chemotherapy with Docetaxel was scheduled for a total of 6-8 cicles in the mHSPC-mCRPC setting, respectively, and up to 9 cycles for Cabazitaxel treatment. Indication to taxane chemotherapy was based on treating physician choice. G8 Questionnaires were collected before start and at the end of chemotherapy. Charlson comorbidity index was recorded for all patients before chemotherapy start. Data comprehensive of age, castrate resistant status , type of taxane used , Growth factors use during treatment, previous and following treatment with ARTAs or other taxanes, number of cycles administered, dose reductions , treatment suspension and treatment definitive interruptions unrelated to progressive disease, were collected and reported. Logistic regression was performed to explore the association between outcomes and baseline age, CCI and G8 score. Receiver Operating Characteristic curves analysis was performed to look for the optimal cut-off value for features significantly associated with treatment outcomes.
