“…Continued tobacco use after a cancer diagnosis has been associated with various detrimental clinical outcomes such as shorter survival (Videtic et al, 2003;Fox et al, 2004;Sardari Nia et al, 2005;Zhou et al, 2006;Nguyenet al, 2010;Parsonset al, 2010;Kenfield, et al, 2011); increased risk of tumor recurrence or development of secondary malignancies (Do et al, 2003;Kawaguchi et al, 2006;Garces et al, 2007;Kaufman et al, 2008;Li et al, 2009;Joshu et al, 2011); poorer response to treatment and an increased risk of treatment toxicities (Monson et al, 1998;Dresler, 2003;O'Sullivan et al, 2003;van der Bol et al, 2007;de Jong et al, 2008;Waller et al, 2011;Petros et al, 2012); an increased risk of surgical complications (Moller et al, 2002;Barrera et al, 2005;Selber et al, 2006;Liu et al, 2011); and inferior bone marrow transplantation outcomes (Marks et al, 2009;Ehlers et al, 2011 ;Tran et al, 2011). Conversely, smoking cessation post-cancer diagnosis has been associated with better pain control and an improved quality of life (Garces et al, 2004;Baser et al, 2006;Daniel et al, 2009;Ditre et al, 2011).…”
