The researchers aim to investigate the outcome (overall survival) of mothers who are diagnosed and/or treated for cancer during pregnancy. Furthermore they want to test the hypothesis that children who were exposed to cytotoxic drugs in utero, or radiotherapy, develop normally (neurologic and cardiologic examination).


Study Type: Observational [Patient Registry]
Study Design: Observational Model: Cohort
Time Perspective: Prospective
Target Follow-Up Duration: 18 Years
Official Title: Oncological Treatment During Pregnancy: Pharmacokinetics of Chemotherapy and Long Term Follow up of the Offspring

Further study details as provided by University Hospital, Gasthuisberg:

Primary Outcome Measures:
  • Follow-up of the mothers diagnosed with cancer during pregnancy [ Time Frame: anticipated ]
    Overall survival

  • Follow-up of the children antenatally exposed to chemotherapy or radiotherapy [ Time Frame: anticipated ]
    neurologic and cardiologic outcome

Biospecimen Retention:   None Retained
serum and sediment of blood; from 2010 on we collect umbilical cord blood

Estimated Enrollment: 5000
Study Start Date: August 2005
Estimated Study Completion Date: April 2025
Estimated Primary Completion Date: April 2025 (Final data collection date for primary outcome measure)
Cancer in Pregnancy - all diagnoses and treatments Children born from mothers diagnosed with cancer during pregnancy
Control group
Children from the general population

Detailed Description:

Prospectively the outcome of mothers diagnosed and/or treated for cancer during pregnancy will be registered and investigated.

In a prospective trial we invite children that were exposed to cytotoxic drugs or radiotherapy in utero for a standardized neurological and cardiological examination. The examinations will be done by qualified psychologists, neurological and cardiological pediatricians.


Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   Female
Accepts Healthy Volunteers:   Yes
Sampling Method:   Non-Probability Sample
Study Population
pregnant women diagnosed with cancer

Inclusion Criteria:

Patients must meet all of the following inclusion criteria:

  • Histologically proven cancer during pregnancy
  • Patients must have adequate bone marrow, renal, hepatic and pulmonary function.
  • World Health Organization (WHO) performance status of 0 or 1
  • > 18 years of age
  • Patients who have given their signed and written informed consent to participate in the trial after fully understanding the implication of the protocol
  • Women receiving any cytotoxic drug during pregnancy are allowed for the assessment of the maternal and fetal outcome
  • Patients are allowed to opt for the pharmacokinetic part or clinical follow-up part of the study only and do not need to participate in both; however, preferentially both study parts should be performed.
  • Women receiving any kind of radiotherapy during pregnancy

Exclusion Criteria:

  • Mentally disabled or significantly altered mental status that would prohibit the understanding and giving of informed consent
