ER/PR Positive HER2 Negative ILC

ER/PR Positive HER2 Negative ILC ER/PR positive HER2 negative invasive lobular carcinoma (ILC) is a type of breast cancer. It has estrogen and progesterone receptors but lacks the HER2 protein. This is important because it means the cancer might respond well to certain hormone treatments.

Knowing about ER/PR positive HER2 negative is key for making the right treatment plans. It helps doctors understand how the cancer grows. This knowledge makes finding and treating the cancer more effective.

Understanding Invasive Lobular Carcinoma

Invasive lobular carcinoma (ILC) is the second most common breast cancer type, making up about 10% of all cases. It starts in the milk-producing lobules and spreads to other tissues. This type of cancer is hard to spot because it can be in many places and on both sides of the breast. Doctors need to treat each patient carefully because of this.

This cancer grows in a way that makes it hard to find early. It spreads out in the breast tissue. This means it’s often found later than other cancers.

To understand how invasive lobular carcinoma compares to other breast cancers, here’s a quick look:

Because of these traits, doctors must be very careful and specific when treating invasive lobular carcinoma. This helps make treatment more effective.

Characteristics of ER/PR Positive HER2 Negative Breast Cancer

Patients with hormone receptor positive breast cancer have cancer cells that respond to estrogen and progesterone. These hormones help the cancer cells grow.

HER2 negative breast cancer means the cancer cells don’t have too much of a certain receptor. This receptor helps tumors grow fast and be aggressive. But without it, the cancer grows slower and is less likely to spread.

Invasive lobular carcinoma ER/PR positive HER2 negative is a special type of cancer. It’s hard to spot on scans and needs careful checks. This shows why regular screenings and new tests are key.

Here’s a look at how different breast cancers compare:

Knowing these differences helps doctors make better treatment plans. It’s important to test regularly to manage hormone receptor positive breast cancer well.

Role of Hormone Receptor Testing in Breast Cancer

Hormone receptor testing is key in fighting breast cancer. It checks if cancer cells have receptors for hormones like estrogen and progesterone. Knowing this helps doctors make better treatment plans, especially for ER/PR positive breast cancer.

What is Hormone Receptor Testing?

This test checks if breast cancer cells have estrogen and progesterone receptors. It’s important for picking the right treatment. If cancer cells have these receptors, they might respond well to hormone therapies.

How is Hormone Receptor Testing Conducted?

Doctors use tissue samples from biopsies or surgery for this test. They look for hormone receptors in the lab. The results help doctors choose the best treatments, making treatment more effective.

An Overview of Breast Cancer Subtypes

Breast cancer is divided into subtypes based on three main receptors: estrogen, progesterone, and HER2. Knowing which receptors are present helps doctors pick the best treatments. It also helps understand the cancer’s growth and spread.

There are three main types of breast cancer:

• ER/PR Positive: These cancers have receptors for estrogen (ER) and progesterone (PR). Hormone therapies work well against them.
• HER2 Negative: This type doesn’t have much HER2 protein. Doctors usually use chemotherapy and hormone therapy.
• Triple-Negative Breast Cancer: This cancer doesn’t have estrogen, progesterone, or HER2 receptors. Chemotherapy is the main treatment.

Knowing about these subtypes is key to finding the right treatments. Each type needs a different approach. For example, ER/PR positive cancers do well with hormone therapies. Triple-negative breast cancer needs strong chemotherapy because it doesn’t respond to hormones or HER2 treatments.

Here’s a table that shows what’s special about each subtype and how they’re treated:

This table shows why knowing the subtype is important for treatment. It helps doctors make the best plans for patients. This leads to better results for those fighting breast cancer.

Treatment Options for ER/PR Positive HER2 Negative Breast Cancer

Treating ER/PR positive HER2 negative breast cancer often means using different treatments together. Each treatment is chosen with the patient and cancer type in mind.

Hormonal Therapy

Hormonal therapy is key for ER/PR positive breast cancer. It targets cancer cells with hormone receptors. Drugs like Tamoxifen or aromatase inhibitors stop estrogen from helping cancer grow. This helps lower the chance of cancer coming back.

Chemotherapy

Chemotherapy is also important for ER/PR positive breast cancer, especially if there’s a high risk of cancer spreading. It uses strong drugs to kill cancer cells that grow fast. Chemotherapy can have side effects but is crucial for getting rid of cancer cells.

Surgery

Surgery is the first step in treating ER/PR positive HER2 negative breast cancer. The surgery type, like a lumpectomy or mastectomy, depends on the tumor and what the patient wants. Surgery removes the cancer, making way for other treatments to finish the job.

Lobular Carcinoma Characteristics

Invasive Lobular Carcinoma (ILC) is a type of breast cancer. It’s harder to find than ductal cancer. This is because it doesn’t form a lump. Instead, it spreads through the breast in a line.

ILC has low cell cohesion, which means cancer cells spread out in the breast. It often loses E-cadherin, a protein that helps cells stick together. Without E-cadherin, cells can’t stick well, helping ILC spread.

To diagnose ILC, doctors use imaging tests like mammography, ultrasound, and MRI. These tests help find signs of ILC. But, a biopsy is needed to confirm it. A biopsy takes a sample and looks at it under a microscope for ILC signs.

• Growth pattern: Single-file infiltration
• Cell cohesion: Low
• Protein expression: Frequent loss of E-cadherin

Prognosis for Patients with ER/PR Positive HER2 Negative ILC

People with ER/PR positive HER2 negative invasive lobular carcinoma (ILC) usually have a good chance of getting better with the right treatment. Finding out early helps a lot with treatment success.

Survival Rates

The survival rates for breast cancer in ER/PR positive HER2 negative ILC depend on many things. Catching it early and treating it fast usually means better survival chances. Studies show that the five-year survival rate can be over 90%, depending on the person’s health and how well they respond to treatment.

Factors Affecting Prognosis

Many things can change how likely someone is to survive with ILC. Important ones include:

• Tumor Size: Smaller tumors usually mean better chances of getting better.
• Lymph Node Involvement: Not having cancer in the lymph nodes is good news.
• Patient Age: Younger people often do better because they have fewer health problems.
• Overall Health: Being healthier helps you handle strong treatments better.
• Genetic Mutations: Some genes affect how well treatments work and the outcome.
• Cancer’s Hormone Receptor Status: Being ER/PR positive means hormone therapy can help a lot.
