Identifying and treating Adenocarcinoma of the lung is vital to a person’s survival. The disease can be difficult to diagnose and treat, but there are several treatments available.
Treatment
Various cancers require treatment, and adenocarcinoma of the lung is one of these. Depending on the stage of cancer, it is possible to get relief with chemotherapy, surgery, radiation, or immunotherapy. These treatments can either stop cancer or slow it down.
In the adenocarcinoma of the lung, the treatment is similar to that of normal adenocarcinoma. Chemotherapy is the standard of care. Adjuvant chemotherapy is also common. Patients who are diagnosed at an early stage have a better chance of recovering.
Molecular targeted therapy has been developed for patients with lung adenocarcinoma. However, the treatment is very expensive. It costs over $20,000 a month. The main risk factor for lung cancer is smoking. Several carcinogens, including radon, can increase the risk of the disease.
Molecular targeted therapy is sometimes used in combination with chemotherapy or angiogenesis inhibitors. This approach is thought to help prolong survival. In addition, patients with EGFR mutations may benefit from tyrosine kinase inhibitors. However, this approach is not very effective.
In a clinical trial, intermittent chemotherapy was used in a small group of patients with advanced adenocarcinoma of their lungs. Patients were eligible for this trial if they had microscopically confirmed adenocarcinoma of the lungs and a smoking history of fewer than 10 packs of cigarettes per year. Patients also had to have an ECOG performance status of 0 or 1.
The treatment consisted of erlotinib and cisplatin. The maintenance dose of erlotinib was associated with diarrhea in one patient.
After a year of treatment, one patient reported complete remission. However, one patient was later diagnosed with metastatic carcinoma of the pancreas. The median survival for all patients was 10.7 months.
Molecular targeted therapy is expensive. In addition, many patients have other health conditions. Consequently, it is important for doctors and patients to coordinate care.
Diagnosis
Symptoms of adenocarcinoma of the lung can vary from patient to patient. Symptoms may include cough, shortness of breath, weight loss, and hemoptysis (blood in the lungs). These symptoms are usually a result of cancer that has not yet spread to other parts of the body.
To diagnose lung cancer, your doctor will take a medical history, perform a physical examination, and look at your lungs. He or she will also consider any risk factors you may have. The doctor may also suggest further testing. This testing can include tests that determine the genetic mutations in cancer.
Your doctor may also suggest a chest x-ray to look for lung cancer. A chest x-ray is painless and can help diagnose lung cancer. You may also have a CT scan, which uses x-rays to create detailed cross-sectional pictures of your body. These tests may also be used to find out how far cancer has spread.
If you have lung cancer, you may also have genetic testing to determine the mutations in your genes. These genes play a role in how cancer grows and spreads.
If you have cancer of the lung that has spread, you may need a biopsy to determine its extent. A biopsy will also let your doctor know if your cancer is cancerous or not. A biopsy can take a tissue sample from the lung and send it to a pathologist to test.
Another imaging test is an MRI scan. MRI scans use radio waves to create images of the inside of the body. This test is especially useful for tumors near the center of the lung. It can also detect the presence of cancer in lymph nodes nearby.
Chemotherapy
Using chemotherapy to treat adenocarcinoma of the lung involves the use of drugs that target cancer cells. These drugs are usually given through a vein as an IV infusion. They can be used on their own or in combination with radiation therapy.
The chemotherapy drug that is used to treat adenocarcinoma depends on the type of cancer, the stage of cancer, the health of the patient, and the location of cancer. The chemotherapy may also include targeted therapy.
The chemotherapy drugs are usually given for a few days or a few weeks. It is important to undergo a blood test before each treatment. The blood test checks the patient’s health and determines if he or she is fit to receive the treatment. The treatment is usually accompanied by anti-sickness drugs.
Adjuvant chemotherapy is used after surgery or resection to kill any remaining cancer cells. This type of chemotherapy is standard for stage I to stage IIIA adenocarcinoma of the lung. The goal of the research is to identify the cellular mechanisms involved in lung cancer and to apply these findings to immunotherapy-based treatment strategies.
Another type of chemotherapy is neoadjuvant chemotherapy, which is used before surgery to shrink the tumor. The chemotherapy drugs are usually given for a couple of days and then stopped.
Chemotherapy is also used to treat cancer in other parts of the body. Several different types of chemotherapy are used for lung cancer. These include docetaxel, carboplatin, and pemetrexed.
The use of chemotherapy and radiation therapy has improved the survival rate of lung adenocarcinoma patients. However, there are also some negative side effects. These include damage to healthy cells and may be permanent. Some of these side effects are severe enough to lead to a decrease in quality of life.
Radiation therapy
During radiotherapy, high doses of radiation are delivered to a specific area of the body to kill cancer cells. It also can be used to ease symptoms related to the disease. It can be combined with chemotherapy, surgery, and other treatments.
The success of radiation depends on the type of radiation used and the stage of cancer. It may also be used to help people live longer. In some cases, it may be used before surgery to shrink the tumor.
Radiation therapy for lung cancer usually involves a series of sessions over a period of weeks or months. Some patients can work part-time during treatment. Others may be unable to work at all. During treatment, you may experience tiredness, weakness, and shortness of breath. You may need to take pain medication, fluids, and oxygen.
In some cases, chemotherapy may be given before radiation. This is done in order to reduce the symptoms of the disease after initial treatment. It also interferes with the ability of the cancer cells to reproduce.
In the early stage of the disease, chemotherapy is usually given before surgery. However, surgery may be used in conjunction with radiation to kill the remaining cancer cells.
A CT scan and positron-emission tomography (PET) scan are used to determine the location of the tumor. In some cases, stereotactic body radiation therapy (SBRT) may be used. This technique involves delivering high doses of radiation over a number of days or weeks. It is different from IMRT.
Radiotherapy for lung cancer can help shrink tumors and improve quality of life. It can also be used to treat cancer that has spread to other parts of the body. In some cases, radiation therapy is used to treat lung tumors before surgery.
Hepatoid Adenocarcinoma
Hepatoid adenocarcinoma of the lung (HAC), also known as pulmonary Hepatoid adenocarcinoma, is a rare primary lung cancer. It is highly malignant and has a poor prognosis. The incidence of this form of cancer is low, but the prognosis is worse than that of other lung cancers.
In most cases, HAL has an advanced stage at the time of diagnosis. The prognosis is poor because of its aggressive nature and its high incidence of invasions. The majority of cases are male, and the majority have a history of smoking.
The histologic features of HAC are similar to those of hepatocellular carcinoma. The tumor cells are eosinophilic, with prominent nucleoli. In some cases, intracytoplasmic lumina are present in a few cells. They produce alpha-fetoprotein (AFP).
Hepatoid adenocarcinoma can occur in any part of the body, including the liver, pancreas, stomach, gallbladder, and uterus. However, it is most commonly found in the stomach. Currently, adjuvant chemotherapy is the most common treatment for HAL. The combination of chemotherapy and immunotherapy is also used in metastatic HAL.
In addition to AFP, hepatoid adenocarcinoma also produces P53. In addition, the tumor cells show evidence of protein formation due to vitamin K deficiency.
In this case, a 57-year-old white male presented with a large mass in the anterior segment of the left upper lobe. Chest X-ray and CT scan showed an 8-cm mass. The tumor was resected and showed poorly differentiated hepatoid carcinoma-like cells. In addition, there was a necrotic appearance to the mass. The resected tumor had a trabecular arrangement, with large tumor cells.
In addition, the histology of the resected tumor revealed abundant HAC tumor cells. This tumor was treated with complete resection and adjuvant chemotherapy.
