- Ages 18 to 50 years
- All sexes
- No healthy volunteers
- Adult
Study population: Potential research subjects will be identified through the Center for Young Onset Colorectal Cancer, a member of the patient's treatment team, the principal investigator, or research team at Memorial Sloan Kettering Cancer Center (MSKCC). All study participants will be recruited from patients under the care of consenting professionals. If the investigator is a member of the treatment team, s/he will screen their patient's medical records for suitable research study participants and discuss the study and their potential for enrolling in the research study. Potential subjects contacted by their treating physician will be referred to the investigator/research staff of the study.
Who may be able to join
- 18-40 years of age and premenopausal (female) or 18-50 years of age (male) at time of diagnosis
- Histologic diagnosis of colorectal adenocarcinoma
- Able and willing to participate in the informed consent process
- Eligible for curative adjuvant or neoadjuvant therapy for colon or rectal cancer
- Willing and able to complete protocol questionnaires
- Rectal patients only: Individuals who will be receiving chemotherapy, followed by chemoradiotherapy (ChemoRT)
Who cannot join
- Prior systemic treatment for this malignancy
- Active or prior secondary malignancy
- History of ovarian resection (if female)
- Pregnant or nursing (lactating) women, where pregnancy is defined as the state of a female after conception until the termination of gestation, confirmed by a positive hCG laboratory test.

About this study
Official title: The Effects of Chemotherapy or Radiotherapy on Reproductive and Sexual Health of Early Onset Colorectal Cancer Patients
The purpose of this study is to find out how cancer treatments (chemotherapy and/or radiation therapy) affect reproductive and sexual health in people with early onset colorectal cancer. The study researchers will observe and track changes in hormone levels and in sexual and reproductive health in people with early onset colorectal cancer. This information will help researchers know more about how cancer treatments affect reproductive and sexual health, including the ability to have children (fertility).

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Hormone biomarker analysisDiagnostic test
For female patients, hormone biomarker analysis will be performed to measure: anti-Mullerian hormone (AMH), estradiol and FSH in the blood. In male patients, hormone biomarkers of testicular function and spermatogenesis will be monitored: testosterone, inhibin B, steroid hormone binding globulin (SHBG) and FSH. Sperm analysis will also be performed in male patients to monitor changes in sperm count.
QoL QuestionnairesBehavioural
All participants will respond to protocol questionnaires, which will include both validated questionnaires as well as non-validated ones. This design will allow for basic demographic, psychosocial and sexual-health-related data to be obtained.
| Study group | Role | What they receive |
|---|---|---|
| Participants with Colon Cancer | This patient population will have hormone biomarker analysis, questionnaire (QOL) administration, and, if the patient is male, semen analysis Receives: Diagnostic Test: Hormone biomarker analysis; Behavioral: QoL Questionnaires | |
| Participants with Rectal Cancer | This patient population will have hormone biomarker analysis, QOL administration, and, if the patient is male, semen analysis Receives: Diagnostic Test: Hormone biomarker analysis; Behavioral: QoL Questionnaires |
What is being measured
The primary outcome is the main question the study is designed to answer.
Change in anti-Mullerian hormone (AMH), estradiol and FSH of oxaliplatin-induced gonadal toxicity in pre-menopausal female patients (<40y)
Measured: Up to 30 months
Change in testosterone, inhibin B, steroid hormone binding globulin (SHBG) and FSH in young male patients (<50y) undergoing therapy for colorectal cancer
Measured: Up to 30 months

What does the primary outcome measure?
Change in anti-Mullerian hormone (AMH), estradiol and FSH of oxaliplatin-induced gonadal toxicity in pre-menopausal female patients (<40y) (time frame: Up to 30 months). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
