      Background:
      Organ transplant recipients (OTR) have an increased risk of developing post-transplant malignancies with lung cancer being one of the most common. We investigated incidence and outcomes of lung cancer in OTR managed at the University Health Network.

      Methods:
      The study population, patient characteristics, treatments and outcomes were summarized from solid OTR databases, our cancer registry and patient charts from January 1, 1980 to December 31, 2015. Univariate Kaplan-Meyer curves estimated overall survival (OS) by histology, stage and chemotherapy.

      Results:
      Amongst 7994 OTR (heart [N=765], lung [n=1668], liver [n=238], kidney [n=3273]), 123 developed lung cancer (1.54%) of which (55) 44.7% occurred in lung OTR; 108 (1.35%) patients had sufficient data for subsequent analyses. Median age: 62 years (29 - 85); male: 66%; smoking status at time of transplant - former/current/never/unknown: 62%/10%/15%/8%. Histologies included non-small cell lung cancer (NSCLC): 81%; small cell lung cancer (SCLC): 10%; neuro-endocrine tumours: 9%. NSCLC: Adjuvant chemotherapy, after it became standard of care (SOC), was given to 16% of eligible NSCLC patients. At recurrence, 28% received chemotherapy while 28% received a TKI. In patients initially presenting with stage IV NSCLC, 18% received chemotherapy and 3% received a TKI. SCLC: For limited and extensive stage SCLC patients, 83% and 60% received SOC chemotherapy, respectively. All: Where chemotherapy dosing was known (n=23), 42% of patients received initial dose reductions. For early stage patients, 22% required dose reduction and 11% had chemotherapy discontinuation due to toxicity. For stage IV patients, 42% required dose reductions and 50% required discontinuations.

      Conclusion:
      Survival was poor in our OTR population compared to historical norms in non-transplant patients. A minority of NSCLC patients received adjuvant or palliative chemotherapy, while most SCLC patients were treated. Both often had sub-standard dosing. Chemotherapy appeared better tolerated in early stage disease.
