Thanks! @hopeful33250 those articles are helpful! I’m a caregiver. My mom was diagnosed with NETs (Primary in lung) in May 2018. She was on Occtreotide from June 2018 to Nov 2019. Based on her scans with mild increase of cancer activity, the oncologist (traditional thoracic lung oncologist) thought Affinitor would be the next option of treatment so we started in December 2019. In February 2020 my mom developed a new dry cough. In March she developed a little shortness of breath and weight loss. We brought this to the pcp and oncologist attention and I specifically asked the oncology team if her medication could be the cause of the cough and shortness of breath and was told it was not likely. Fast forward to April 3, 2020, new PET scan revealed pleural effusions on the lungs so it was deemed pneumonia. She was treated with two rounds of antibiotics and steroids, no real improvement. Finally on April 21, it was determined she was experiencing toxicity from the Affinitor and stoped the medication. May 8th dotatate shows pneumonitis. Now we’re at a point of treating the inflammation with a much higher dose of steroids, oxygen and an inhaler, praying that the pneumonitis resolves itself with time. I wanted to see if anyone faced similar circumstances and had any tips for home remedies or techniques that helped with shortness of breath while we go through the process.

This article from cure today references pneumonitis as a possible side effect of cancer treatments, specifically noting Affinitor. https://www.curetoday.com/publications/cure/2015/summer-2015/pneumonitis-a-delayed-reaction
Beyond the side effects listed with the everolimus medication, wish I had read this articles in advance for a bit more information.

Separately, we recently spoke to a NET specialist and were looking forward to my mom starting care with this new team.
