Stage IV lung adenocarcinoma

I would like to ask about a situation where a patient has been coughing for a long time, leading to chest pain and side abdominal pain, and subsequently sought medical attention.
It was discovered that there is pleural effusion, and after hospitalization and examination, stage IV lung adenocarcinoma was diagnosed.
All tests have been conducted, and cancer cells have not metastasized to the liver, brain, or bones, and there are no genetic mutations.
Why is it still classified as stage IV? The patient has completed the first round of chemotherapy and will need to wait three weeks for the next treatment.
However, the patient continues to experience chest pain despite taking strong pain medications, including controlled substances.
What can be done to help the patient feel more comfortable and alleviate the pain? Additionally, what is the expected survival rate in this situation? The doctors have not provided any information.
Please help clarify.
Thank you.

DEAR OZ: Cancer staging is assessed using the T (tumor size), N (lymph nodes), and M (metastasis) system.
If pleural effusion is related to cancer, it indicates metastasis.
If pain persists, a transdermal fentanyl patch can be used.
The average survival period is around 6 to 9 months, but individual responses to treatment vary; some patients have survived over 4 to 5 years.
So, we will do our best.
Changhua Hospital cares about you.

More Info

Understanding Stage IV Lung Adenocarcinoma involves recognizing the complexities of cancer staging, treatment options, pain management, and survival rates. In your case, the diagnosis of Stage IV lung adenocarcinoma, despite the absence of metastasis to the liver, brain, or bones, can be attributed to the presence of pleural effusion (fluid accumulation in the pleural space) associated with the cancer. This is a common characteristic of advanced lung cancer, where the cancer has spread to the pleura, even if it hasn't metastasized to distant organs.

Pain Management
Pain management in patients with advanced lung cancer is critical for maintaining quality of life. The persistent chest and side pain you mentioned, even after chemotherapy, can be attributed to several factors. These may include the direct effects of the tumor, inflammation, or even the side effects of chemotherapy itself. It’s important to communicate openly with your healthcare team about the pain levels and the effectiveness of the current pain management regimen.

Given that you are already on strong pain medications, including controlled substances, it may be beneficial to explore additional pain management strategies. These can include:
1. Adjusting Pain Medications: Sometimes, a combination of medications can provide better relief than increasing the dosage of a single medication. This might include non-opioid analgesics, adjuvant medications like gabapentin or pregabalin for nerve pain, or even corticosteroids to reduce inflammation.

2. Interventional Pain Management: Techniques such as nerve blocks or epidural injections can provide significant relief for localized pain.

3. Palliative Care Consultation: Engaging a palliative care team can be invaluable. They specialize in managing symptoms and improving quality of life for patients with serious illnesses.

4. Complementary Therapies: Techniques such as acupuncture, massage therapy, or mindfulness practices may also help alleviate pain and improve overall well-being.

Survival Rates
Regarding survival rates for Stage IV lung adenocarcinoma, it is important to understand that statistics can vary widely based on individual circumstances. The prognosis for Stage IV lung cancer is generally poor, with median survival rates often cited between 6 to 12 months. However, these figures are averages and do not account for individual variations in response to treatment, overall health, and other factors.

The fact that there are no gene mutations and that the cancer has not spread to other organs can be seen as a positive aspect, as these factors can influence treatment options and outcomes. Some patients may live for several years with Stage IV lung cancer, especially with advancements in targeted therapies and immunotherapies that have emerged in recent years.

Conclusion
In summary, while the diagnosis of Stage IV lung adenocarcinoma presents significant challenges, there are various avenues for pain management and treatment that can enhance quality of life. It is crucial to maintain open communication with your healthcare providers about pain levels and treatment efficacy. Additionally, understanding the individual nature of cancer prognosis can help set realistic expectations and empower you and your family to make informed decisions regarding care and treatment options. Always consider seeking a second opinion or consulting with specialists in oncology and palliative care to explore all available options.
