Effect of Menstrual Cycle on Traumatic Systemic Response

An interventional study of modified radical mastectomy in Systemic Inflammatory Response Syndrome, sponsored by Kocaeli University. Status unknown. Open to female participants, including healthy volunteers. Per ClinicalTrials.gov, last updated 2017-09-18.

The sponsor has not verified this record recently (last verified Sep 2017), so the status shown — last known as Active, not recruiting — may be out of date.

Study summary

It is aimed to evaluate pathophysiology of systemic responses to trauma via using interleukin (IL) -1 and IL-6 levels and determining timing of surgery through phases of menstrual cycle.

Read the detailed description

89 female breast cancer patient who underwent modified radical mastectomy included into study. Menstrual history and hormone levels were used to determine menstrual phase: luteal, follicular, and other. IL-1β and IL-6 levels, which are related to severeness of inflammation, were measured one day before and one day after surgery. Those are statistically analysed to show effect of timing of breast surgery on responses to trauma in postmenopausal and premenopausal women during different phases of their menstrual cycles

Inclusion criteria

  • female patients
  • who underwent modified radical mastectomy for breast cancer
  • who signed forms

Exclusion criteria

Exclusion Criteria:

  • For premenopausal patients taking oral
  • for patients taking hormone replacement therapy.
Terms in these criteria, in plain language(3)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

Postmenopausal

Periods have stopped for good: usually no period for 12 months in a row without another medical reason, sometimes confirmed by a blood test (FSH).

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Sep 18, 2017, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
