November 8, 2026 updated by: GenMont Biotech Incorporation

To Evaluate the Efficacy of Probiotics in Improvement and Prevention of Chemotherapy Associated Side Effectes in Patients With the Breast Cancer

Chemotherapy-associated side-effects would affect therapeutic effect, quality of life, and cause permanent harm to breast cancer patients. This study is designed to explore after consumption of probiotics of lactobacillus composite strain powder sachets for 6 months in breast cancer chemotherapy, and whether the improvement of meliorate the side effects, further assists patients completing the chemotherapy.

Status

Status

Indicates the current recruitment status or the expanded access status.
Active, not recruiting

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

In 2020, the incidence rate of women's breast cancer in Taiwan was up to 82.1% . The death rate increased to 16%; in 2021, the ranking rose to no.3, and the death rate grew up to 24.6%. In the decades, breast cancer gradually becomes the dominant malignant women's cancer in Taiwan. Besides the lumpectomy, chemotherapy is one of the dominant and important treatments for breast cancer. Beyond the effects of chemotherapy, several side effects rise up. The most common chemotherapy are anthracyclin drugs (doxorubicin and epirubicin) and taxane (docetaxel and paclitaxel ). There are common side effects including neutropenia, hair loss, vomiting, diarrhea, stomatitis, mucositis, peripheral neuropathy, dermatitis, nephrotoxicity, and hepatotoxicity. Currently, most treatments for chemotherapy-induced side effects are symptomatic treatment, but there is no good solution to prevent it.
