How to effectively treat lung cancer at 75?

Question

Hello doctor,

My mom turned 75 last month, and two weeks after her birthday, we received the worst news of our lives. She has been diagnosed with small-cell lung cancer. The oncologist said it is an extensive stage, meaning it has spread beyond the lung.

She was a smoker for about 40 years but quit 10 years ago. Her ECOG performance status is 2, and she has existing heart failure with an ejection fraction of 38 percent, along with type 2 diabetes with an HbA1c of 8.1. The cardiology team is concerned about whether her heart can tolerate chemotherapy, specifically the Etoposide and Carboplatin regimen that was recommended. She also had a minor stroke two years ago, so adding immunotherapy such as Atezolizumab is making the neurologist cautious.

Her sodium level came back low at 128 due to SIADH, which the oncologist says is common with this type of lung cancer. We sit through appointments and nod, but we do not fully understand what the extensive stage of small-cell lung cancer means for someone her age with all these other conditions.

Is there any realistic chance of her beating this, or at least having a good quality of life for some time?
What should we be aiming for her in terms of treatment? Our family is united and wants to do everything possible, but we also do not want her to suffer needlessly.

Please help.

Thank you.

Hello,

Welcome to iCliniq.com.

I understand your concern.

In simple terms, extensive-stage small cell lung cancer (SCLC) means the cancer has spread beyond the lungs, often to other organs or lymph nodes, making it very aggressive and difficult to cure completely, especially at the age of 75 with other health problems.

The recommended chemotherapy with Etoposide and Carboplatin is usually the standard treatment and can sometimes shrink the cancer and improve symptoms, but it is strong medicine, and your mother’s heart failure, diabetes, and prior mini stroke do increase the risk of complications.

Adding immunotherapy (like Atezolizumab) could help, but her heart and prior neurological issues make it more complicated. Low sodium (SIADH, syndrome of inappropriate antidiuretic hormone secretion) is common in small-cell lung cancer and can cause confusion, fatigue, and weakness, so it needs careful correction during treatment.

Her realistic objectives are usually twofold:

- Controlling the symptoms and improving quality of life and reducing cancer growth and progression where feasible, as opposed to curing her illness.- She needs to receive her treatment in a well-designed manner by a multidisciplinary group of doctors from oncology, cardiology, neurology, and supportive care so that she may gain from treatment without unnecessary suffering.

One can advocate for symptom management, preventing hospital admissions, eating well and feeling energized, and monitoring the status of her heart function and salt levels, while chemotherapy is only used in cases where her general status will allow.

With a united family and good medical supervision, she can have a meaningful, comfortable time with a reasonable quality of life, even if the cancer itself cannot be eliminated. Need a conservative treatment.

I hope this helps.
