The single most actionable insight: endocrine side effects (hypothyroidism, adrenal insufficiency, ICI-induced diabetes) are the #1 driver of mid-treatment distress and discontinuation consideration, yet patients report poor proactive communication from oncology teams at the moment those lab values shift.

  • Keytruda's efficacy narrative is powerfully patient-driven, with NED and remission stories circulating widely across forums and blogs, creating strong pull among newly diagnosed patients weighing immunotherapy vs. chemotherapy.
  • Endocrine immune-related adverse events (hypothyroidism, adrenal insufficiency, ICI-induced diabetes) dominate mid-treatment distress conversations and are the most cited reason patients consider or actually pursue discontinuation.
  • Cost and coverage anxiety, especially the question of paying out-of-pocket after 2-year insurance limits, is a persistent and emotionally charged thread that shapes both initiation and continuation decisions across income levels.
  • The quality-of-life trade-off framing (Keytruda vs. chemo) is the dominant decision lens at treatment initiation, but patients report that oncology teams underestimate how burdensome cumulative low-grade side effects become over months of maintenance therapy.
