Trial summary

The endogenous digitalis-like compounds (DLC)are steroid hormones synthesized and released from the adrenal gland.They are integrated in the feed-back system of the Hypothalami-Pituitary-Adrenal gland axis.One of their remarkable function is to induce apoptosis in malignant cells.

About this study

The endogenous digitalis-like compounds (DLC)are steroid hormones synthesized and released from the adrenal gland.They are integrated in the feed-back system of the Hypothalami-Pituitary-Adrenal gland axis.One of their remarkable function is to induce apoptosis in malignant cells. Recently, accumulating data point to the possibility of using synthetic DLC as new anti-cancer drugs. Less is known about the endogenous metabolism of these compounds in cancer patients.

Proceeding from preliminary clinical data which demonstrated significantly reduced DLC plasma levels in breast cancer patients and from in vitro data which showed an impaired release of DLC towards stress stimuli in athymic nude mice,we put up the hypothesis that a latent adrenal insufficiency with low DLC levels facilitates the induction and progression of tumor diseases.

Read the detailed description

To pursue this question about endogenous DLC metabolism in cancer patients we intend to start with the measurement of DLC plasma levels in breast cancer patients at the time of first diagnosis and compare them to women with benign breast disease as well as healthy women.

Aim of the Study

  • To evaluate the basal DLC plasma concentrations in cancer patients at the time of first diagnosis and the function of the HPA axis, with focussing on breast cancer patients.
  • To analyze a potential change of HPA function and, in parallel, DLC plasma concentrations in the course of therapy, with special respect to treatment failure.
  • To establish a potential correlation between DLC plasma concentrations and risk factors in BC.

Patients and Methods

Patients:

  1. 50 - (100) patients with breast cancer at the time of first diagnosis

II. 50 - (100) patients with a benign disease of the breast

III. 50 - (100) women undergoing plastic surgery of the breast

IV. 50 - (100) women who need no further exploration after visit in ambulance (=normal population)

  1. additionally a group of 25 - 50 students (age 20-40) will be analyzed in a pilot study

Methods:

Time-schedule for Group I (Group II. - IV. alike, according to disease and/or situation)

  • Day of first presentation of the woman at the clinic
  • Day of first diagnosis, i.e. biopsy/FNA
  • Day of start of treatment: operation, chemo-/radiotherapy (tst = 0)
  • Day + 30, + 60, + 90
  • 6 month and 1 year after start of treatment

The Group V. (students) will be analyzed in a special schedule, preceding the study 1-2 months:

  • 4 weeks before an important exam
  • a day before the exam (-3 days)
  • a day after the exam (+ 3 days)
  • 2 weeks after the exam
  • 6 weeks after the exam

Parameters

Biochemistry (Group I. - V.)

  • Basal DLC plasma concentration
  • Basal serum Cortisol concentration
  • Basal plasma ATCH concentration
  • Basal Aldosterone/Renin concentration
  • Electrolytes (potassium, sodium, calcium, chloride)

Pathology/Immunohistochemistry (Group I. + II., when benign, including last 4 points)

  • Tumor size
  • lymph node status
  • E/P receptors
  • Grade
  • HER2/neu
  • Bcl-2
  • Ki67
  • p53

Radiology (Group I.)

If abdominal CT available measurement of size of the adrenal glands

Endocrinologic tests (Group I. - IV.)

  • Dexamethasone-test (low dose):
  • 2 mg Dexamethasone p.o. at 24:00
  • measurement of Cortisol and DLC at 8:00 the next morning
  • ACTH-test:
  • basal plasma concentrations of Cortisol, DLC and ACTH
  • administration of 250 µg ACTH (Synachten®) i.v.
  • measurement of Cortisol and DLC after 30 min. and 60 min.
  • Facultative: Metapyrone test at following time intervals:
  1. Dexamethasone-test
  • around the time of first presentation (± 5 days)
  • around the time of start of treatment (± 5 days); corresponding times for Group II.- IV.
  • Day + 30, +60, +90
  • 6 month and a year after start of treatment
  1. ACTH-test
  • On the day of first presentation
  • On the day of start of treatment; corresponding times for Group II.- IV.
  • Day + 30, +60, +90
  • 6 months and one year after start of treatment

Psychometric test for Stress Evaluation (Group I. - V.)

  • at the day of first presentation (Students: in between the last 2 weeks before an exam)
  • at the end of the study

Questions about this trial

What is this clinical trial studying?

An observational study of Breast Neoplasms and Fibrocystic Disease of Breast, run by Hadassah Medical Organization at 1 site in Israel.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: withdrawn, as of the sponsor's last update on 8 Apr 2011. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Israel. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study was withdrawn before enrolling participants, so there are no results.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 8 Apr 2011.
