Do I really have a chance of winning a debate when my side is to continue meds when CA develops?
Thank you for slides • Jim Lewis • Jean Fred Colombel • Corey Siegel (also for photos of Tom!)
Important questions in pts who develops cancer on IBD meds: Did the medicine cause the cancer? What is the risk of: - continuing the med in terms of worsening cancer or - discontinuing the med in terms of worsening IBD?
Let’s consider three types of cancer: Skin Cancer Lymphoma Solid Tumors
Case • 50 year old male • 30 year history of small bowel Crohn’s • 1 prior bowel resection • Current meds – 6MP + Adalimumab • 3 BM per day • Colonoscopy – few scattered aphthous ulcers (i1) in the neo-TI
Case (cont) • 2 years prior diagnosed with Non Melanoma Skin Cancer (Basal Cell Ca) • 2 weeks ago newly diagnosed with Squamous Cell Cancer
Is skin cancer caused by or are patients at increased risk from… azathioprine/6MP Methotrexate antiTNFs

Clinical Questions • Is skin cancer risk increased by therapy? • Thiopurines – yes • Methotrexate – don’t know, probably not • Biologics – no NMSC, maybe melanoma • If so, does the risk of continuing therapy outweigh the benefits? • In this case – consider stopping thiopurine • Uncertain if risk will decline • Annual skin exam and regular use of sunscreen and hats

Questions • Does immunosuppressant therapy increase the risk of lymphoma? • Do the benefits outweigh the risks? • What do you do when a lymphoma develops in the setting of IBD meds?
AZA/6-MP are probably related to Lymphoma (Meta-analysis): SIR 4.06 SIR = 4.06, 95% CI 2.01 – 7.28 Kandiel A et al. Gut. 2005:54:1121-25

Clinical Questions • Does immunosuppressant therapy increase the risk of lymphoma? • Thiopurines – yes, but risk may revert after discontinuation • antiTNFs – Probably not • Combination – Yes and probably more than monotherapy
Hepatosplenic T Cell Lymphoma • 41 cases from FDA AERS among patients with IBD1 • Thiopurine alone 17 • Anti-TNF alone 1 • Combination therapy 23 • Characteristics2 • Median age 22.5 (12 – 58) • 93% male • Median time since initiation of thiopurines ~6 years • Deepak P.

Case – Stop or Continue? • 39 yo male CD in remission on 6MP/IFX for 8 yrs. • Now with weight loss, sweats, and low grade fevers
After consulting with the oncologist…. …we stopped the 6MP/antiTNF, but after 3 months of chemorx, the antiTNF was resumed. We did not restart the 6MP.
On CT: Hepatosplenic T cell lymphoma – enlarged spleen, otherwise nonspecific. Thiopurine must be stopped!
Case Continue or Stop? • 58 yo female with severe UC who has been on IFX/6MP (50mg/d) for past 1yr • Just diagnosed with intraductal breast CA (T1N0MX) • Strong FHx breast CA, pt opts for bilateral mastectomy • After consultation with oncology, the decision is to cont meds
No clear association between thiopurines/antiTNFs and solid tumors in IBD

Should we continue or stop IBD meds if a cancer develops? Depends on IBD
Deep Remission If in deep remission, maybe stopping IBD meds is ok and not restarting them
