Guide for use:
Chemotherapy is cancer treatment that achieves its antitumour effect through the use of antineoplastic drugs that inhibit the reproduction of cancer cells by interfering with DNA synthesis and mitosis.
Record the first or earliest date chemotherapy was administered during the initial course of treatment. The initial course of treatment includes all treatments administered to the patient from diagnosis and before disease progression or recurrence.
The start date of the chemotherapy is recorded regardless of whether the course of treatment is completed as intended, and regardless of the intent or timing of chemotherapy.
Multiple entries are not permitted.
Dates relating to targeted therapies using a chemotherapy agent are included. Targeted therapies are treatments that use drugs or other substances to identify and attack specific cancer cells.
Dates of surgery, radiotherapy and other systemic treatments are collected as separate items. However, if a patient receives treatment with a protocol that includes different types of systemic therapy agents, for example, a chemotherapy agent and a hormone therapy agent, record the start date of treatment in both relevant data items.

Collecting the start and finish dates for treatment modalities will enable an estimate of treatment duration.
