Antibiotics and immunotherapy

My wife has stage 4 metastatic melanoma which was diagnosed in January. The illness had spread with main issue being a tumour in her brain.   A course of dab tram worked wonderfully well pushing everything back to ‘residual abnormality’ . This lasted until November when we were informed that an MRI scan from October had evidenced that a tumour had returned and a new  one appeared. We discovered this whilst my wife was in hospital with an infection which turned out to be pneumonia. She was put on a course of amoxicillin. 
initially it was suggested the tumour would be treated with radiotherapy. Subsequently the MDT decided she should immediately be put on a course of immunotherapy- IPi/nivo. The first course was started last week. 
this week following a visit to our GP my wife was re admitted to hospital. The pneumonia had not cleared up and had worsened. She was put on antibiotics amoxicillin and clarythromycin. Our oncologist took her off the antibiotics suggesting it may compromise the immunotherapy. I have since checked the internet and seen a number of investigations that confirm this may be the case and significantly compromise the effectiveness oh her immunotherapy. Following a CT scan yesterday which evidenced a severe respiratory infection she has been put back on antibiotics this time doxycycline with the agreement of the oncology team. She is on a dose of 500mg for the next 4 days.

we are very concerned about the potential effect on her immunotherapy but equally that if her infection is not treated than it could worsen

really worried

  • Hi Ken,

    Thanks for getting in touch. My name is Kenny and I am one of the Cancer Information Nurse Specialists on the Macmillan Support Line. I’m sorry to hear that your wife’s is suffering from a severe respiratory infection when she had just recently commenced her immunotherapy.  Uncertainty about what the future may hold can be very difficult to cope with, so this cannot be easy right now.  

    Immunotherapies involve the use of medications to stimulate the person affected immune system, as this may help them attack cancer cells.  Several types of immunotherapies are considered for stage 4 melanoma treatment, and Ipilimumab and nivolumab, classified as checkpoint inhibitors (a specific type of immunotherapy) can be very effective.  However, studies have shown that use of accumulated antibiotics can adversely affect the outcomes for some immunotherapy treatments.  Your wife’s team are having to take a risk assessment right now to try and give her the best way forward with her treatment.  Based on the risk, her team have decided to treat her respiratory infection with anti-biotics as the best option for her right now.  They will be aware that anti-biotics can compromise the effectiveness of her immunotherapy but need to have her strong enough to tolerate the treatment. 

    I fully appreciate your concern so you might find it helpful to get back in contact with your specialist/consultant or Clinical Nurse Specialist (CNS) to find out more information.  If possible, next time you speak to your wife’s team it might be helpful to make a list of questions to ask before you speak to her doctor or nurse.  Resolving her respiratory infection appears to be the biggest concern right now for her team but raise your understandable concerns with them so they can give you a full insight into their decision-making process.
