An ethical dilemma in a case of probable MDS

A medical oncologist is faced with an ethical dilemma that he presents to the Figure 1 community:

“A 71 year-old man with dementia presented 6 months ago with slowly evolving pancytopenia x 1 year. Ten months ago his WBC was 2.25 x 10^9/L, ANC 1.04 x 10^9/L, hemoglobin 11.0 g/dL, hematocrit 34%, MCV 103 fL, and platelets 172 x 10^9/L. Two months ago his hemoglobin had fallen to 7.8 g/dL, ANC to 0.46 x 10^9/L, and platelets 110 x 10^9/L. Non-neoplastic causes for cytopenias such as medication effect or nutritional deficiency were ruled out. Peripheral blood mutation testing showed DNMT3A R882C in 22% of sequencing reads and U2AF1 S34F in 21% of sequencing reads.

The patient’s wife is his health care proxy; the patient himself lacks decision-making capacity. He knows own name and his wife’s name, but does not know the date, the President, or the name of the medical facility; he frequently makes nonsensical and off-topic statements during office visits. The patient’s wife declined a diagnostic bone marrow biopsy on his behalf. The patient was treated with darbepoetin once his Hb fell below 10 g/dL since his endogenous EPO level was only 60 U/L but he is now transfusion dependent. Today he was found to have 10% circulating myeloblasts.

Last week the patient’s wife was diagnosed with advanced breast cancer. She still does not want the patient to have a bone marrow biopsy nor to have any treatment beyond transfusions. How would you approach this patient?”

The oncology specialist includes some more context in the comment section:

“She says it is not a scenario they had discussed, but she clearly cares deeply for him and has his best interests in mind. It is difficult for us to watch a treatable malignancy evolve before our eyes but autonomy is a core value so we respect her wishes. Since he seems to get benefit from transfusions, we’ll continue that, which unfortunately makes him ineligible for the local hospice. This is actually a difficult problem for hematological malignancy patients: a large proportion of hospices do not allow transfusions, but for our patients transfusions can be part of palliative care.”
