HOrmone Therapy Immediately After Histological Diagnosis of Breast Cancer (HOTBreast)

Hormone Therapy Initiation Immediately After Histological Diagnosis of Breast Cancer, Can it Make Any Difference?

Breast Cancer is a public health issue worldwide. The time from diagnosis to treatment initiation varies from country to country and regionally within a country. Early diagnosis and prompt treatment initiation are key factors in patient survival rates.

Currently there is a rising trend, with a high percentage of patients with "Luminal" like breast cancer only undergoing adjuvant endocrine therapy.

Authors argue that tumor biology alterations after introducing very early endocrine therapy might have a prognostic and therapeutic impact and should be studied.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Unknown

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Selected patients of female gender, above 50 y.o, and after a biopsy of Luminal-like Breast Cancer will go under aromatase inhibitor, from the diagnosis day till the surgical therapy to be decided (if so).In this study are going to be included patients that refuse surgical treatment, remaining this way in an "active surveillance". This last group is going to be randomised in order to recieve hormontherapy plus placebo vs hormontherapy plus acetolisalicilic acid.

In this way, authors want to investigate if:

  1. st This approach influences the tumor biology
  2. nd This approach influences tumor pathologic response and progression free survival.
  3. rd It is a valid approach and in which grade, for patients that refuse surgical treatment

Phase

Phase
