Chemo-tox man picture from the FA (last page of the hem and onco section) works well for me in these types of questions.

lovebug Bleomycin Induces free radical formation -> breaks in DNA strands.(Anti-tumor effect) FA19, pg431. and other tissues have Bleomycin Hydrolase. but Lung doesn't. So lead to Pulmonary fibrosis. +

yotsubato Bleomycin is the big boy of cancer treatment. I've never heard of chlorambucil and its not in FA. +1

vulcania I had never heard of chlorambucil either and after researching it found out that it's also an alkylating agent, specifically a nitrogen mustard - same as busulfan, so you weren't wrong! Based on what FA says re: bleomycin & busulfan (extrapolating this to chlorambucil), they both cause pulmonary fibrosis & skin hyperpigmentation, however, in the Lange Pharmacology flashcards it says that the hyperpigmentation with busulfan is from adrenal insufficiency so I guess you would expect to see symptoms of that as well if the same applies to chlorambucil? +1

vulcania jk ignore my previous comment. just checked uptodate and it doesn't list hyperpigmentation as a side effect of chlorambucil. +
