Managing bone metastasis in colorectal cancer patients is a complex process that demands comprehensive knowledge and careful handling. The occurrence of bone metastases in patients with colorectal cancer is around 3-7%, often indicating disease progression.

An extensive study on large Italian bone metastases scrutinized:

  • cancer treatments

  • traits of bone metastases

  • skeletal-related incidents

  • disease outcomes

to gain deeper comprehension of this complex condition.

Defining Bone Metastasis

Bone metastasis refers to the dissemination of cancer cells from the primary tumor to other locations in the body, including the bones. Colorectal cancer patients had higher bone metastasis (BMM) rates than anticipated, with some even experiencing multiple bone metastases. It ranged from 16% when liver metastases were accompanied by other organs invasion, up to 34% when both liver and lung metastasis involved other organs invasion. Bone and brain metastases are among the most concerning complications for colorectal cancer patients, with brain metastases being a particularly challenging issue.

The spine is the most commonly affected site (65%), and osteolytic lesions are more prevalent than mixed lesions (81% versus 13% of bone lesions, respectively). The presence of bone metastasis in colorectal cancer patients can have severe implications on their overall health and prognosis.

Impact on Prognosis

The effect of bone metastases on survival rates is significant, with an average 5-year survival rate of approximately 8.1% and a median survival of typically less than 10 months. Metastases may disrupt the normal structure of a bone, result in extreme discomfort, or even lead to pathologic fractures and other potentially hazardous skeletal-related occurrences.

The 5-year survival rate for skeletal metastases patients is about 8.1%. This is fairly low as median survival is usually less than 10 months. Patients who received zoledronic acid had a median overall survival of 10 months (95% CI 8.09–11.91 months).

Key Factors Influencing Spread

Several factors contribute to the spread of colorectal cancer to bones. Rectal cancer, lymph node invasion during primary tumor surgery, and lung metastases at any stage are widely recognized risk factors for bone metastases. This can have dire implications if left unchecked or untreated. Patients with primary rectal cancer are more likely to manifest bone metastases.

Additionally, six studies examined the correlation between bone metastases and lung metastases, revealing a significantly augmented likelihood of bone metastasis for patients with lung metastases. Comprehension of these factors can assist in early identification and handling of bone metastasis in colorectal cancer patients.

Life Expectancy with Colon Cancer Bone Metastases

Life expectancy for patients with colon cancer bone metastases varies depending on multiple factors, such as the stage of cancer, treatment advances, and individual patient characteristics. An analysis of life expectancy for these patients includes median survival statistics, treatment advances, and comparison of outcomes.

Overall, the median survival following diagnosis of bone metastases was 7.00 months. The range of survival rates for colorectal cancer patients with bone metastasis is from 7 months to 9.4 months, with an average 5-year survival rate of approximately 8.1%.

Median Survival Statistics

The median survival post-diagnosis of bone metastases in colorectal cancer patients differs based on individual patient factors and the existence of other metastatic sites. The two register studies by Khattak et al. and Riihimäki et al. reported a median overall survival after diagnosis of metastatic disease in patients who only had bone metastasis, ascertaining a median overall survival of 5.1 and 5.5 months, respectively.

Furthermore, osteoblastic lesions or the presence of only one bone lesion correlate with a longer median survival in comparison to osteolytic lesions or the presence of two or more bone lesions.

Treatment Advances and Survival

Progress in colorectal cancer treatment has resulted in noteworthy amelioration in overall survival rates for colorectal cancers. The 3-year overall survival rate has risen from 15.2% for individuals diagnosed between 2004 and 2015 to 75% for those diagnosed between 2016 and 2019.

Novel treatment options, such as fruquintinib and combination therapies, have demonstrated encouraging results in prolonging survival for patients with metastatic colorectal cancer. The use of targeted therapies, such as bevacizumab, has demonstrated improvements in the treatment of metastatic colorectal cancer, assisting in delaying disease progression and potentially increasing survival in patients with bone metastases.

Comparing Outcomes

Outcomes for colorectal cancer patients with bone metastasis can significantly differ based on the cancer stage, treatment strategies, and individual patient factors. The median survival for these patients ranges from 7 months to 9.4 months, with a 1-year survival rate of 20% for patients with osseous metastases.

Treatment approaches can have a marked effect on the outcomes of colorectal cancer patients with bone metastasis, with various treatment strategies, including:

  • chemotherapy

  • surgery

  • radiotherapy

  • systemic therapy

Bone metastases management, including surgical resection, is being utilized for both colon cancer patients and colorectal cancer patients.

The survival rate for colorectal cancer patients with bone metastasis who undergo systemic therapies is demonstrably higher compared to those receiving localized treatments.

Managing Quality of Life with Bone Metastases

Prioritizing the quality of life for patients with bone metastases is an integral part of colorectal cancer treatment and management. This includes effective pain management, prevention of skeletal-related events, and the provision of supportive care options.

For example, palliative care has been shown to alleviate cancer-related symptoms like pain and to enhance emotional well-being as well as overall life quality in responders.

Pain Management

Controlling pain in patients with bone metastases is key to preserving life quality. The most effective methods for pain management in patients with bone metastases from colorectal cancer include:

  • Radiotherapy

  • Nonsteroidal anti-inflammatory drugs (NSAIDs)

  • Bisphosphonates

  • Interventional radiology

Additionally, the care team may suggest other pain control methods such as relaxation techniques, meditation, deep breathing, massage, physical therapy, and hot/cold therapy.

Skeletal-Related Events

Skeletal-related events (SREs) can significantly impact the quality of life for patients with bone metastases from colorectal cancer. Radiation and pathologic fractures were observed in 45% and 10% of patients, respectively. Bisphosphonates such as ibandronate, anti-RANKL monoclonal antibody denosumab, and bone-targeted agents like zoledronic acid may be employed to prevent skeletal-related events in colorectal cancer patients with bone metastases.

Radiation therapy can also be used to reduce bone pain and impede the progression of cancer in metastatic lesions.

Supportive Care Options

Supportive care options for patients with bone metastases from colorectal cancer may include monthly treatment, chemotherapy to alleviate symptoms, and best supportive care.

Regular physiotherapy for patients with bone metastases can offer a number of advantages, including enhanced functional capacity, muscle strength, and lean mass.

It is also essential to provide nutritional support to improve patients’ overall function and treatment outcomes.
