Oesophageal adenocarcinoma stage III is a serious form of cancer where the disease has grown beyond the inner layers of the oesophagus and may have spread to nearby tissues or lymph nodes, though not to distant organs. Understanding this stage helps patients and families make informed decisions about treatment and care.

What is Stage III Oesophageal Adenocarcinoma?

Stage 3 oesophageal adenocarcinoma represents a significant advancement of cancer within the oesophagus. At this stage, the disease may have grown through the thick muscle wall and outer layer of the oesophagus, sometimes reaching nearby structures. These structures can include the tissue covering the lungs, called the pleura, the outer covering of the heart known as the pericardium, or the diaphragm, which is the muscle at the bottom of the rib cage that helps with breathing.^[2]

In stage 3 disease, the cancer might also have spread to up to six nearby lymph nodes, which are small structures that are part of the body’s immune system. However, there is no sign of the cancer spreading to distant body parts like the liver or lungs at this stage.^[2]

Adenocarcinomas are cancers that develop in gland cells. In the oesophagus, these cells produce mucus in the lining. This type of cancer usually forms in the lower part of the oesophagus, near the stomach, and is often linked to a condition called Barrett oesophagus.^[14]

How Stage 3 Oesophageal Adenocarcinoma is Classified

The staging of oesophageal cancer is quite complex. It depends on the type of cancer, how abnormal the cells look under a microscope (the grade), and whether doctors are staging based on scans and tests before treatment or after surgery. When doctors use scans and tests to determine the stage, this is called clinical staging. When they examine tissue removed during surgery, this is pathological staging.^[2]

Stage 3 adenocarcinoma can be further divided into subcategories depending on how far the cancer has grown and how many lymph nodes are involved. The staging system uses letters and numbers to describe the tumor size (T), lymph node involvement (N), and whether the cancer has spread to other parts of the body (M).^[4]

For clinical staging, stage 3 adenocarcinoma means the cancer has spread into the thick muscle wall or further, and may be present in nearby lymph nodes. In pathological staging, after surgery, doctors might classify the disease as stage 3A or 3B based on more precise measurements of tumor depth and the exact number of affected lymph nodes.^[2]

Symptoms of Stage 3 Oesophageal Adenocarcinoma

Symptoms of oesophageal cancer often develop gradually and can significantly affect daily life. One of the most common symptoms is painful or difficult swallowing, a condition doctors call dysphagia. Patients may first notice trouble swallowing solid foods, and as the tumor grows, even liquids can become difficult to swallow.^[14]

Weight loss is another frequent symptom. This happens partly because eating becomes uncomfortable or difficult, leading people to eat less. The body may also lose weight because the cancer itself changes how the body uses energy and nutrients.^[7]

Many people experience pain behind the breastbone. This chest discomfort can be persistent and may worsen when eating. Some patients also develop a persistent cough or hoarseness in their voice if the tumor affects nearby structures.^[14]

Indigestion and heartburn are common, especially since oesophageal adenocarcinoma often develops in the lower part of the oesophagus. Daily chest pains and fatigue can also occur as the disease progresses. Some patients may notice they feel tired all the time, even when they haven’t been particularly active.^[19]

Treatment Approaches for Stage 3 Oesophageal Adenocarcinoma

Treatment for stage 3 oesophageal adenocarcinoma typically involves a combination of different therapies. The healthcare team will suggest treatments based on individual needs and circumstances, working with patients to develop a personalized treatment plan.^[6]

Chemotherapy is usually combined with radiation therapy to treat stage 3 disease. When these two treatments are given during the same time period, it’s called chemoradiation. This combination may be offered before surgery to shrink the tumor, a strategy called neoadjuvant therapy. It can also be given after surgery, which is known as adjuvant therapy.^[6]

For patients who aren’t healthy enough for surgery or who prefer not to have surgery, chemoradiation may be offered as the main treatment. The most common chemotherapy drugs used include combinations such as cisplatin with fluorouracil, carboplatin with paclitaxel, or other similar pairings.^[11]

Surgery is often a key part of treatment when possible. The most common operation is called an esophagectomy, where surgeons remove part or most of the oesophagus and sometimes part of the stomach. The remaining stomach is then pulled up and connected to the remaining oesophagus. This can now be done using minimally invasive robotic techniques, which can lead to better recovery.^[9]

Targeted therapy drugs may be used for stage 3 adenocarcinoma tumors, particularly those at the junction between the oesophagus and stomach. These are usually combined with chemotherapy. For example, trastuzumab is used for tumors that test positive for a protein called HER2. These drugs work by targeting specific features of cancer cells.^[6]

Immunotherapy is a newer treatment approach that helps the body’s own immune system fight cancer. Drugs like pembrolizumab or nivolumab may be offered for stage 3 oesophageal cancer, either in combination with chemotherapy as a first treatment or after surgery if cancer cells remain.^[11]

Nutrition During Treatment

Good nutrition is extremely important for people with stage 3 oesophageal cancer. Because swallowing can be difficult and treatment can affect appetite, patients may have a feeding tube placed to help them gain weight and maintain good nutrition during treatment. This tube allows nutritious liquids to be delivered directly to the stomach, bypassing the narrowed or damaged oesophagus.^[6]

After surgery, when part of the stomach has been removed, patients typically need to eat smaller, more frequent meals throughout the day. Instead of three large meals, eating four to six smaller meals helps the body digest food more comfortably. This adjustment is necessary because the restructured digestive system has less capacity than before.^[9]

Life After Treatment

Recovery from stage 3 oesophageal cancer treatment is a journey that requires patience and adjustment. Physical restrictions are common after surgery, and the body needs time to heal and adapt to changes in the digestive system. Some people experience ongoing side effects like brain fog, memory lapses, or fatigue that can last for months.^[9]

However, many patients find ways to maintain quality of life through staying physically active, keeping journals to track symptoms and important information, and connecting with support groups. These strategies help people cope with the physical and emotional challenges that come with cancer treatment and recovery.^[19]

Survival and Outlook

The outlook for stage 3 oesophageal cancer depends on many individual factors, and statistics cannot predict what will happen in any particular case. According to data from England, around 20 out of 100 people with stage 3 oesophageal cancer survive their cancer for five years or more after diagnosis.^[17]

These statistics don’t take into account what treatments people received or other health conditions they might have had. Individual outcomes can vary significantly based on factors like overall health, response to treatment, and the specific characteristics of the cancer.^[17]

Advances in treatment approaches, including minimally invasive surgery techniques, new chemotherapy combinations, targeted therapies, and immunotherapy, continue to improve outcomes for patients with stage 3 oesophageal cancer. Choosing a treatment center with experience in treating this disease and having access to the latest treatment options can make a difference.^[16]

Support and Care

Living with stage 3 oesophageal cancer involves more than just medical treatment. Palliative care is a medical specialty that focuses on providing comprehensive care for people with serious illness. It helps manage symptoms, provides emotional support, and helps patients and families make decisions about care.^[24]

Palliative care specialists work alongside the cancer treatment team to address pain, difficulty swallowing, nutritional issues, and psychological symptoms like anxiety or depression. This type of care isn’t just for the end of life—it’s beneficial throughout the cancer journey to help people live as fully as possible.^[24]

Many treatment centers offer multidisciplinary teams that include surgical oncologists, medical oncologists, radiation oncologists, nutritionists, social workers, and other specialists. This team approach ensures that all aspects of a patient’s care are coordinated and that no need goes unaddressed.^[9]
