Pertuzumab + trastuzumab maintenance
A record of what you experience
One cycle per page. Each medicine has its own symptom table. Mark the worst symptoms since your last review, when they occurred and what they stopped you doing. Overlapping symptoms can be recorded under more than one medicine; you do not have to identify the cause.
These are patient-language severity prompts, not a validated questionnaire or a formal CTCAE grading tool. Your team assigns the clinical grade. Serious symptoms override the columns: call without waiting to decide a severity level.
Pertuzumab and trastuzumab are given by infusion every 21 days after the chemotherapy phase of the metastatic treatment plan. Duration depends on benefit, tolerance and the agreed plan; this is not a fixed one-year adjuvant course.
The four pages are reusable recording sheets, not a prescribed four-cycle course. Ask for additional sheets as needed.
