Stage IV colon cancer, the most advanced stage, indicates that the cancer has spread from the original location in the colon to other parts of the body, a process known as metastasis. The symptoms of metastatic colon cancer can vary widely based on the location of metastasis. Some common symptoms include abdominal pain, changes in bowel habits, or blood in the stool. However, the manifestation of symptoms can be more complex, depending on whether the cancer has spread to the liver, lungs, peritoneum, bones, or other organs.

In this article, we will discuss the symptoms of stage IV colon cancer, which is one of the colon cancer stages. More details will be elaborated in subsequent sections.

Identifying Common Symptoms

Common symptoms of stage IV colon cancer can include:

  • Constipation

  • Diarrhea

  • Changes in stool color or shape

  • Rectal bleeding

  • Abdominal pain

These symptoms are typically detected through colon cancer screening methods and can be managed with medications and nutritional support.

Fatigue is a common symptom, often characterized by a sudden onset, not related to activity or exertion, and not relieved by rest or sleep. Weight loss is another symptom attributed to various factors, including the direct impact of tumor growth, which may result in abdominal pain, alterations in bowel habits, and bleeding.

Anemia, resulting from chronic hemorrhage from the tumor, leading to decreased levels of red blood cells, can serve as an early warning sign and may contribute to a delayed diagnosis of colon cancer.

When Cancer Spreads Beyond the Colon

When colon cancer spreads beyond the colon, it can affect other organs such as the liver and lungs. This process is called metastasis, where cancer cells detach from the original tumor and spread via the bloodstream or lymphatic system to establish new tumors in other organs.

Signs that the cancer has spread to the liver may include:

  • Jaundice

  • Abdominal pain

  • Swelling

  • Itching

  • Loss of appetite

  • Liver enlargement

Shortness of breath can indicate that the cancer has spread to the lungs.

Regular colorectal cancer screening can help detect colon cancer, including colon cancers and bowel cancer, in its early stages and prevent individuals from the risk to develop colon cancer as it spreads to other organs.

Recognizing Less Common Signs

Beyond the physical symptoms, stage IV colon cancer may also produce psychological effects, including anxiety and depression. The overwhelming diagnosis, fear of disease progression, and the physical symptoms and side effects of treatment often contribute to the development of anxiety and depression.

Psychological symptoms like heightened anxiety and depressive symptoms are often associated with the physical manifestations of cancer, such as pain, fatigue, and cancer-specific distress, which can be considered as risk factors.

Less common physical symptoms may include bone pain, which can be caused by bone metastasis, bone weakness, fractures, or high calcium levels in the blood, among other reasons.

Diagnostic Procedures for Advanced Colorectal Cancer

Diagnosing stage IV colon cancer is a significant step in identifying the best treatment plan. Diagnostic procedures, such as imaging tests, biopsies, and blood tests, help determine the extent of the metastasis and inform subsequent treatment decisions.

The subsequent sections will provide more details about these diagnostic procedures.

Imaging Tests to Visualize Metastasis

Imaging tests are instrumental in the diagnosis of stage IV colon cancer. Tests like CT scans provide a detailed image of the colon, which is essential for understanding the spread of cancer to other organs. A virtual colonoscopy, also known as a CT scan for colon cancer diagnosis, uses imaging to internally visualize the colon without the requirement of endoscope insertion.

Other imaging tests like chest X-rays can visualize metastasis by identifying the spread of cancer to the lungs or any bone metastases. Positron emission tomography (PET) scans are crucial in identifying metabolically active tumors and assessing the extent of cancer spread to other tissues or organs. These scans are especially important for monitoring the effectiveness of treatment and identifying any potential recurrence in patients.

Biopsy: Confirming the Diagnosis

A biopsy is a medical procedure where a small piece of tissue is removed from an abnormal area in the colon for laboratory testing. This procedure is typically performed during a colonoscopy using a needle. Several types of biopsies, such as endoscopic biopsy, surgical biopsy, and needle biopsy, can be utilized in the diagnosis of stage IV colon cancer.

A biopsy is vital for verifying a colon cancer diagnosis. If cancer cells are identified within the sample by the pathologist, it provides substantial evidence of the presence of colon cancer. Furthermore, analyzing a biopsy provides valuable insights into the cancer’s aggressiveness and potential treatment responses by evaluating the cancer cells’ characteristics under a microscope.

Examining a biopsy can also determine whether colon cancer has metastasized.

Blood Tests and Tumor Markers

Blood tests play a significant role in the diagnostic process of stage IV colon cancer. They help rule out other diseases and disorders and can monitor the progression of cancer and the effectiveness of treatment. Typical blood tests used to detect stage IV colon cancer include the Carcinoembryonic Antigen (CEA) test and Full blood count (CBC).

Tumor markers are substances produced by cancer cells that can be detected in the blood. They play a critical role in monitoring the progression of stage IV colon cancer by providing estimates of prognosis, determining the stage of cancer, detecting residual cancer after treatment, and monitoring cancer growth and treatment response. Specific tumor markers associated with colorectal cancer are carcinoembryonic antigen (CEA) and carbohydrate antigen (CA 19.9). A decrease in tumor markers may signify that the treatment is yielding positive results.

Treatment Approaches for Stage IV Colon Cancer

Chemotherapy treatment in progress

The treatment of stage IV colon cancer primarily aims to prolong life and enhance the quality of life. Treatment options include:

  • Chemotherapy

  • Targeted therapies

  • Radiation therapy

  • Surgery

Each of these treatments serves a particular purpose and plays a crucial role in managing the disease.

These treatment methods will be examined more thoroughly in the subsequent sections.

Chemotherapy and Targeted Therapies

Chemotherapy and targeted therapies form the frontline of treatment for stage IV colon cancer. Chemotherapy involves the use of drugs to eliminate cancer cells, and it is often employed after surgery to eradicate any remaining cancerous cells and manage the growth of tumors. Commonly prescribed chemotherapy drugs include 5-Fluorouracil (5-FU) and Capecitabine (Xeloda).

Complementing chemotherapy is targeted therapy, which concentrates on specific molecules within or on the surface of cancer cells, inhibiting signals that facilitate their growth or division, and ultimately helping to kill cancer cells. This personalized approach can be beneficial for certain patients with stage IV colon cancer.

While chemotherapy and targeted therapies do not provide a cure for metastatic colorectal cancer, they constitute a fundamental component of the treatment strategy, often employed in conjunction with other therapies such as surgery or targeted treatments. However, these treatments may come with their own set of side effects, such as:

  • Hair loss

  • Mouth sores

  • Loss of appetite

  • Nausea

  • Diarrhea

  • Changes in nails and skin

Radiation Therapy as a Palliative Measure

In managing stage IV colon cancer, radiation therapy plays a significant role, particularly in treating colon cancer as a palliative measure. This means it aims to reduce symptoms and improve quality of life, rather than curing the cancer. It provides pain relief by improving symptoms such as intestinal blockages, bleeding, and pain.

Though beneficial, radiation therapy can also come with its share of side effects, including appetite loss, constipation, and fatigue. It is crucial to weigh the potential benefits of radiation therapy against its possible side effects.

Despite potential side effects, radiation therapy has proven effective in relieving specific symptoms of advanced colon cancer.

Surgical Interventions in Advanced Cases

In certain cases, surgical interventions may be considered to remove tumors and alleviate symptoms. Surgical resection combined with systemic treatment is the preferred approach for patients with resectable metastases. The available surgical interventions include the removal of cancerous polyps, sections of the colon or rectum, and performing a colonostomy. These interventions offer benefits such as potential improvement in survival, symptom relief, and in some cases, a curative approach for limited metastatic disease.

Survival rates for surgical interventions in advanced colon cancer vary significantly. The 5-year survival rates range from 22% to 90%, reflecting the diverse stages of colon and rectal cancer. Localized diseases demonstrate higher survival rates, while stage IV diseases exhibit lower rates. It’s crucial to recognize that combining surgery with other treatments, such as chemotherapy, is a common practice to enhance outcomes. However, potential risks or complications associated with surgical treatment may include:

  • Adhesion and small bowel obstruction (SBO)

  • Thrombosis

  • Infections

  • Port site metastases

  • Anastomotic leakage

  • Pneumonia

  • Bowel obstruction/ileus

The Role of Palliative Care in Managing Symptoms

Palliative care is vital in symptom management and enhancing the quality of life for individuals with stage IV colon cancer. It offers comprehensive support to meet the physical, emotional, and psychological needs of patients.

Subsequent sections will discuss strategies for pain management and how palliative care addresses concerns about the quality of life.

Pain Management Strategies

Pain is a common symptom in stage IV colon cancer. Pain management strategies include medications, nerve blocks, and alternative therapies. Prescribed medications for pain management in stage IV colon cancer consist of opioids like oxycodone, oxymorphone, and non-opioids such as acetaminophen and NSAIDs like ibuprofen.

Nerve blocks are utilized in managing cancer-related pain by providing temporary relief through the injection of local anesthetics into specific nerves. Alternative therapies like:

  • acupuncture

  • reflexology

  • acupressure

  • hypnosis

have also shown effectiveness in managing pain in colon cancer patients. Non-pharmaceutical pain management techniques such as cognitive behavioral interventions and coping interventions can also be beneficial for cancer patients.

Addressing Quality of Life Concerns

Palliative care teams address the quality of life concerns by:

  • Providing emotional support

  • Managing side effects

  • Coordinating care

  • Offering counseling, therapy, and support groups aimed at helping patients manage their emotions and enhance their overall quality of life.

Strategies for addressing side effects include:

  • Pain and symptom management

  • Information sharing and advance care planning

  • Psychological and spiritual support

  • Surgical evaluation

Palliative care teams also coordinate care by maintaining communication with the medical care team and strive to enhance the patient’s quality of life.

Making Decisions About End-of-Life Care
