the selective serotonin reuptake inhibitors (SSRIs) fluoxetine, paroxetine and citalopram prevented apoptosis of Burkitt lymphoma cells in vitro;1 These antidepressant drugs are considered similar in effectiveness and act to increase synaptic levels of serotonin, with minimal effects on other neurotransmitters.2 It was not receptor antagonism, but prevention of serotonin reuptake that interfered with apoptosis that was otherwise promoted by serotonin.1 The authors reached the tentative conclusion that the action of serotonin was mediated through the serotonin transporter (SERT).1 In view of the lack of serotonin oxidative metabolites and the inability to reverse serotonininduced apoptosis by monoamine oxidase inhibitors, the authors suggested that SERT, itself, somehow drives apoptosis upon binding to serotonin. However, these in vitro results required serotonin concentrations that are unattainable systemically, except in cases of carcinoid or lung cariroma ectopic serotonin secretion;3 yet, in such cases, serotonin does not appear to adversely affect tumor growth. In two previous clinical studies, it was reported that women taking paroxetine had a 7-fold increased risk of breast cancer; those taking the older tricyclic antidepressants, that increase levels of both serotonin and norepinephrine, as well as antagonize histamine-1 receptors, had a 2-fold higher risk.4 However, in a subsequent report within that year, the same authors announced that paroxetine was associated with an increased risk of only 70%, instead of the 7-fold or 700% reported previously.5 Such information has created considerable confusion over the use of antidepressants, especially in cancer patients. Antidepressants had previously been reported to promote the growth of some tumors in laboratory tests,6,7 along with certain antihistamines.8 In those reports, amitriptyline and fluoxetine, along with the histamine-1 receptor antagonists loratadine, astemizole only in low doses and hydroxyzine, increased melanoma growth in mice; however, high doses did not.9,10 Other studies suggested that amitriptyline and desipramine may increase the risk of breast cancer.11–13 Yet, there is an unexplained paradox in that many publications report opposite results. For instance, hydroxyzine was shown to be cytotoxic against human breast cancer cells14 and other histamine-1 receptor antagonists were protective against tumor cell proliferation.15 Moreover, fluoxetine, imipramine and citalopram demonstrated antineoplastic properties16, elsewhere amitriptyline inhibited the growth of renal cell adenocarcinoma.17 In fact, amitriptyline, fluoxetine and paroxetine were all found to protect neurons from the damaging effects of stress.18 Histamine has been reported to promote cancer by stimulating cell division and activating suppressor T-cells.19,20 Drugs with histamine-1 receptor antagonist actions GUEST EDITORIAL
