According to recent advances in psychoneuroimmunology concerning the neurobiochemistry of emotions, the pshychological status of cancer patients should be investigated in relation to the function of the psychoneurodocrine system, in an attempt to put into evidence possible cancer progression-related alterations, particularly those involving the dopaminergic pathways, which play a fundamental role in the perception of pleasure. In fact, the decreased capacity of feeling pleasure is one of the most frequent psychic symptoms occurring in cancer patients. Rorschach's test has been proven to be an appropriate psychological tool to investigate psychic condition including sexual and spiritual profiles. On this basis, a study was planned to evaluate if a relation exists between psychological response to Rorschach's test and immunoneuroendocrine status of cancer patients. The immune status was investigated by measuring lymphocyte subsets and serum levels of IL-2 and IL-10. The neuroendocrine status was analyzed by evaluating the endocrine response of PRL, GH and cortisol to an oral administration of apomorphine (0.01 mg/kg b.w.), a dopaminergic agent able to explore dopaminergic sensitivity. The study included 40 cancer patients (breast cancer: 15; colorectal cancer: 14; lung cancer: 11), 21 of whom showed distant organ metastases. Rorschach's test demonstrated a simultaneous suppression of sexual and spiritual profiles in 31/40 (78%) patients, without significant differences in relation to either tumor histotype or disease state. A normal decline in PRL levels and a normal increase in those of GH and cortisol was observed in 29/40 (73%), 5/40 (13%) and 9/40 (23%) patients. The percent of normal responses of PRL, GH and cortisol was higher in patients with normal than in those with altered response to Rorschach's test, even though only the difference in PRL and cortisol response was statistically significant. Patients with normal sexual and spiritual expression at Rorschach's test showed a significantly higher number of total lymphocytes, T lymphocytes, T helper lymphocytes and NK cells with respect to the patients with altered psychological response, whereas no difference was found in T cytotoxic lymphocyte mean number. IL-2 and IL-10 mean serum concentrations were lower and higher, respectively, in patients with altered than in those with normal response to Rorschach's test, even though only the difference in IL-10 values was statitistically significant. This preliminary study, carried out to analyze the psychological status of cancer patients in relation to neuroendocrine and immune conditions, would suggest that neoplastic disease is characterized by a simultaneous suppression of sexual and spiritual profiles, and that this is associated with neuroendocrine alterations and immunosuppression.
根据心理神经免疫学在情绪神经生物化学方面的最新进展,应结合心理神经内分泌系统的功能来研究癌症患者的心理状态,以试图找出可能与癌症进展相关的改变,特别是那些涉及多巴胺能通路的改变,多巴胺能通路在愉悦感的感知中起着重要作用。事实上,愉悦感降低是癌症患者最常见的精神症状之一。罗夏测试已被证明是一种用于调查包括性和精神层面在内的心理状况的合适心理工具。在此基础上,计划开展一项研究,以评估对罗夏测试的心理反应与癌症患者的免疫神经内分泌状态之间是否存在关联。通过测量淋巴细胞亚群以及白细胞介素 -2(IL -2)和白细胞介素 -10(IL -10)的血清水平来研究免疫状态。通过评估催乳素(PRL)、生长激素(GH)和皮质醇对口服阿扑吗啡(0.01毫克/千克体重)的内分泌反应来分析神经内分泌状态,阿扑吗啡是一种能够探究多巴胺能敏感性的多巴胺能药物。该研究纳入了40名癌症患者(乳腺癌:15例;结直肠癌:14例;肺癌:11例),其中21例有远处器官转移。罗夏测试显示,31/40(78%)的患者同时出现性和精神层面的抑制,这与肿瘤组织类型或疾病状态均无显著差异。在29/40(73%)、5/40(13%)和9/40(23%)的患者中观察到PRL水平正常下降以及GH和皮质醇水平正常升高。PRL、GH和皮质醇正常反应的百分比在对罗夏测试反应正常的患者中高于反应异常的患者,尽管只有PRL和皮质醇反应的差异具有统计学意义。在罗夏测试中性和精神表达正常的患者相对于心理反应异常的患者,其总淋巴细胞、T淋巴细胞、辅助性T淋巴细胞和自然杀伤细胞的数量显著更多,而细胞毒性T淋巴细胞的平均数量未发现差异。对罗夏测试反应异常的患者中,IL -2和IL -10的平均血清浓度分别低于和高于反应正常的患者,尽管只有IL -10值的差异具有统计学意义。这项旨在分析癌症患者心理状态与神经内分泌和免疫状况关系的初步研究表明,肿瘤疾病的特征是性和精神层面同时受到抑制,并且这与神经内分泌改变和免疫抑制有关。
