What the full journey looks like.
Lutetium therapy isn't a single appointment — it's a 6 to 8 month process with distinct phases. Most patients say the biggest source of stress isn't the treatment itself but not knowing what's coming next. This guide walks you through every phase, in detail.
Before treatment
1–4 weeks
Eligibility scan, blood tests, decisions about timing and center.
During treatment
6–8 months
4–6 cycles, repeated every 6–8 weeks. Hour-by-hour walkthrough of each cycle.
After each cycle
Days 1–7 after each
Radiation safety at home, managing mild side effects, recovery routines.
After treatment ends
Lifelong
Follow-up scans, monitoring markers, planning if cancer returns.
What this guide covers
Each phase has its own deep-dive page. Some highlights:
- Before treatment — what scans you need, how to prepare, decisions about timing
- A day in the cycle — hour-by-hour walkthrough of a treatment day
- How many cycles will I need? — 4 vs 6, and when to adjust
- Radiation safety at home — practical guidance for the first few days
- Long-term outlook — what to expect for years after treatment
A typical timeline
For a hypothetical 6-cycle Lu-177 PSMA therapy course starting January 2026:
- Late Dec 2025: PSMA PET scan, eligibility confirmed
- Mid Jan 2026: Cycle 1
- Feb 2026: Cycle 2
- Apr 2026: Cycle 3 (often with interim scan around now)
- May 2026: Cycle 4
- Jun 2026: Cycle 5
- Aug 2026: Cycle 6 (last cycle)
- Nov 2026: First follow-up PSMA PET (3 months after last cycle)
- Then every 3–6 months for years
For Lu-177 DOTATATE therapy (4 cycles, 8 weeks apart), the schedule is similar but compressed to about 6 months.
