The Uncommon Cancer: Lymphohistocytoid Mesothelioma (LHM) 🧬

A Rare Type of Mesothelioma That Needs Immediate Attention

Greetings to all readers! We are grateful to have your attention as we bring you information about Lymphohistocytoid Mesothelioma (LHM), a rare type of mesothelioma that needs immediate attention. Mesothelioma is a rare form of cancer that develops in the lining of the lungs, heart, and abdomen. However, the incidence of LHM is even rarer compared to other types of mesothelioma. Thus, there is a critical need to educate people about this uncommon cancer.

This article aims to provide comprehensive knowledge about LHM, including its definition, diagnosis, causes, and treatment options. We will also discuss the symptoms, prognosis, and advancements in research regarding LHM. Keep reading to learn more about this rare form of mesothelioma that needs immediate medical attention.

What is Lymphohistocytoid Mesothelioma (LHM)?

Lymphohistocytoid Mesothelioma is a rare type of cancer that develops in the mesothelial tissue. It is a subtype of biphasic mesothelioma, which has a combination of epithelioid and sarcomatoid subtypes. The cancerous tumors in LHM show a unique pattern, wherein the mesothelial tissue has lymphocyte and plasma cell infiltration. This pattern is an unusual one, and thus, clinicians may struggle to diagnose LHM.

Who is at Risk of Developing LHM?

There is no direct correlation between the history of asbestos exposure and LHM. However, studies suggest that people who were exposed to asbestos, radiation, and other environmental factors, such as chemicals, have a higher predisposition to developing mesothelioma. Generally, LHM affects men more than women, and the median age of diagnosis is 60 years old.

What Are the Symptoms of LHM?

Like other types of mesothelioma, LHM symptoms may take years to manifest, and the symptoms may vary depending on the affected area. Some of the typical symptoms of LHM include the following:

SYMPTOMS	DESCRIPTION
Chest pain	Continuous pain in the chest area, especially while breathing or coughing.
Shortness of breath	Difficulty in breathing or feeling breathless even with light physical activity.
Fever	Unusual elevation of body temperature, which indicates an infection or inflammation.
Coughing	Continuous cough that lasts for over two weeks.
Fatigue	Extreme weakness, tiredness or lack of energy.

How is LHM Diagnosed?

Since LHM is a rare type of cancer, it can be difficult to diagnose. Your doctor will ask for a detailed medical history, conduct a physical examination, and order diagnostic tests to confirm LHM. The following are the most common diagnostic tests used to diagnose LHM:

1. Imaging Tests: This includes X-rays, CT scans, MRI, and PET scans. These tests can determine the location, size, and shape of the tumor.

2. Biopsy: This is a crucial diagnostic test. During a biopsy, a small tissue sample is extracted from the affected area for further laboratory analysis to confirm the existence of LHM cells.

3. Blood Tests: Blood tests are used to check the level of tumor markers in the blood. If the tumor marker levels are high, it may indicate the presence of cancer cells in the body.

What are the Treatment Options for LHM?

The treatment for LHM is similar to other types of mesothelioma. The goal is to remove as much of the cancer cells as possible, alleviate symptoms, and prolong life expectancy. The following are the common treatment options for LHM:

1. Surgery: Surgery is an option if the cancer is localized and has not metastasized to other parts of the body. The surgeon will remove as much of the tumor as possible.

2. Chemotherapy: Chemotherapy uses a combination of drugs to attack cancer cells in the body. Chemotherapy is effective in reducing the size of the tumor and alleviating symptoms.

3. Radiation Therapy: Radiation therapy or radiotherapy uses high-energy radiation to kill cancer cells. It is often used when surgery is not possible or the tumor is inoperable.

What is the Prognosis for LHM?

The prognosis for LHM is often poor since most people are diagnosed in advanced stages of the disease. However, the prognosis depends on several factors such as the age, overall health, and stage of cancer. It is important to note that early diagnosis and prompt treatment can improve the prognosis and quality of life of the patient.

What are the Advances in LHM Research?

There are ongoing studies and clinical trials to develop new treatments and improve the prognosis of patients with LHM. Researchers are exploring new diagnostic methods, targeted therapies, and immunotherapies to treat LHM.
