Carboplatin + Paclitaxel (Endometrial Cancer): what to expect, day by day

Endometrial Cancer21-day cycle8 effects documented

An every-3-week infusion pair. Expect lowered blood counts (white cells low around day 11), hair loss, and — building up over cycles — tingling/numbness in the hands and feet from paclitaxel.

Carboplatin + paclitaxel IV every 3 weeks. Onset is nadir-based (days since infusion). Paclitaxel's nerve tingling is CUMULATIVE — it builds over cycles rather than tracking a single day.

Get help straight away — this is true on any regimen, on any day.

A temperature of 100.4°F (38°C) or higher during treatment can mean a serious infection while your blood counts are low. Call your team or go to the ER — do not wait it out.

Also urgent: trouble breathing or chest pain · swelling of the face, lips or throat · new confusion or fainting · shaking chills · not being able to keep fluids down.

This is standing guidance shown to everyone. Nothing on this page is based on anything about you, and nobody is monitoring you.

One of the 8 entries below is marked provisional. They are shown because leaving them out would be its own distortion, but they have not yet been checked against the source document by a person, and they are not presented as authoritative. Every provisional entry is labelled where it appears.

Timed to the cycle

Day 1 is the day of your infusion. These are the effects a retrievable document ties to a day range for this regimen — not a prediction about you.

Hypersensitivity / infusion reaction

During or just after an infusion

A reaction during the infusion (flushing, rash, back pain, trouble breathing) — most often in the first hour of the first or second dose. You'll get pre-medication to prevent it and be watched closely.

Call your team urgently: Trouble breathing, throat tightness, or dizziness during the infusion — tell staff at once.

reported by about 41% of people; severe in 2% · Timing is part of what this effect is · from Paclitaxel

Neutropenia

Typically around days 8–28

A temporary drop in infection-fighting white cells; the low point (nadir) is usually around day 11.

Call your team urgently: A temperature of 100.4°F (38.0°C) or higher — an emergency.

reported by about 80-90% of people; severe in 63% · Timing from the manufacturer’s prescribing information · from Carboplatin, Paclitaxel

Thrombocytopenia

Typically around days 8–28

A drop in platelets (which help blood clot) — carboplatin's main dose-limiting effect; the low point is usually around day 21. Watch for easy bruising or bleeding.

Call your team: Bleeding that won't stop, or black/tarry stools.

severe in 10% · Timing from the manufacturer’s prescribing information · from Carboplatin

Anemia

Typically around days 8–28

A drop in red cells that can cause tiredness and breathlessness, building over cycles.

Call your team: New or worsening breathlessness, chest pain, or a racing heart.

severe in 10% · Timing from the manufacturer’s prescribing information · from Carboplatin, Paclitaxel

Hair loss

Typically around days 14–21

Hair loss is common and starts about 2-3 weeks in; it grows back after treatment ends.

reported by about 87% of people · Timing from a drug-monograph reference · from Paclitaxel

Not tied to a cycle day

These build with the number of doses, or are measured from when treatment started, so a cycle day would be the wrong shape for them. Each keeps the timing its own source states.

Peripheral neuropathy (cumulative)

builds over cycles; dose-dependent

Numbness or tingling in the hands and feet that builds up with repeated cycles (dose-related). Report it early — your team may adjust the dose. It often improves after treatment but may not fully resolve.

Call your team: Numbness that makes it hard to button clothes, walk, or feel the floor.

reported by about 60% of people; severe in 10% · from Paclitaxel

Arthralgia / myalgiaPROVISIONAL

Aching joints and muscles that typically come on 2-5 days after the infusion and settle before the next cycle.

reported by about 60% of people; severe in 3-8% · from Paclitaxel

Nausea

Sickness in the first 24 hours is the "acute" phase and usually peaks 2-3 hours in; anything from 24 to 120 hours is the "delayed" phase.

Usually mild-moderate (carboplatin is only moderately nausea-causing) and well controlled with anti-nausea medicine.

Call your team: Can't keep fluids down for more than 12 hours.

severe in 15% · Timing from a clinical guideline · from Carboplatin, Paclitaxel

Where this comes from

S1. Schiller JH, ECOG 1594 (carboplatin+paclitaxel arm, advanced NSCLC) (2002) — PMID 11784875
S2. Paclitaxel (Taxol) FDA prescribing information — FDA label
S3. Carboplatin (Paraplatin) FDA prescribing information — FDA label

Timing windows on this page rest on:

Taxol (paclitaxel) FDA prescribing information — “Neutrophil nadirs occurred at a median of 11 days” source
Definitional — an infusion reaction is one that occurs during or shortly after the infusion — “The timing is part of what the term denotes; there is no empirical claim here to source.”
BC Cancer Drug Manual — paclitaxel — “usually complete, generally occurs 14-21 days after administration of paclitaxel; onset sudden, often occurring in a single day” source
MASCC/ESMO antiemetic consensus — emesis phases — “acute 0-24 h, delayed 25-120 h, overall 0-120 h” source

A window appears here only where a retrievable document ties it to a drug in this regimen. Where nothing could be found, the window was removed rather than estimated — so a missing time is an honest gap, not an oversight.
