Amisulpride in the short-term treatment of depressive and physical symptoms in cancer patients during chemotherapies

Introduction Amisulpride is a substituted benzamide that, at low doses, selectively blocks D2 and D3 presynaptic dopamine receptors, enhancing dopaminergic transmission in frontal cortex and limbic areas. Many clinical studies versus placebo, tricyclic antidepressants and selective serotonin reuptake inhibitors showed amisulpride antidepressant effect, supporting its safety and rapid onset of action. In oncological population, depression is quite frequent and difficult to treat because of the particular sensitivity of cancer patients to the antidepressants’ side effects. Goals of work The aims of this study were to evaluate efficacy, safety and tolerability of low doses of amisulpride (50 mg) in oncological, depressed patients during chemotheraphy. Materials and methods One hundred six consecutive cancer outpatients with depressive symptoms were treated in a prospective, intention to treat, 4-week study, and were evaluated in single-blind with Montgomery Asberg rating scale for depression (MADRS), clinical global impression (CGI) and dosage record treatment emergent symptom scale (DOTES) to assess side effects of treatment. Main results After 4 weeks of treatment, scores of MADRS and CGI significantly improved (p < 0.002; p < 0.001, respectively), with a reduction of depressive symptoms concerning both emotional (such as apparent sadness, reported sadness, inner tension, etc.) and physical cluster (such as lack of appetite, reduction in weight, tiredness and insomnia) with good tolerability (only two patients dropped out). Conclusions This study is the first trial on the use of amisulpride in a cohort of oncological, depressed patients during chemotherapy. Amisulpride demonstrated high efficacy and safety. Controlled studies are needed to confirm these preliminary data.     

鼻咽癌CT灌注成像及其生物学相关性研究

目的研究鼻咽癌CT灌注值与肿瘤微血管密度（MVD）、肿瘤分期的关系，探讨多层螺旋CT灌注成像对鼻咽癌的临床应用价值。方法49例鼻咽部CT灌注检查中，鼻咽癌组30例，鼻咽癌放疗后组14例，正常鼻咽部5例，测量鼻咽癌和鼻咽黏膜位置的血流量（BF）、最大强化指数（PEI）、峰值到达时间（TTP）及血容量（BV）作为灌注指标，其中16例鼻咽癌活检组织行免疫组织化学CD34单抗染色后，Weidner方法计数MVD。各组灌注值比较行方差分析，CT灌注值、肿瘤分期与MVD之间行Spearman等级相关分析。结果49例中1例鼻咽癌灌注检查失败。鼻咽癌组（29例）肿瘤CT灌注值BF为（48．6±16．9）ml·100g^-1·min^-1，PEI为（32．3±7．9）HU，TTP为（17．5±4．9）s，BV为（12．8±4．4）ml·100g^-1；正常对照组（5例）BF、PEI、TTP、BV值分别为（15．9±5．9）ml·100g^-1·min^-1、（12.6±1．3）HU、（22．6±6．9）s、（3．5±0．5）ml·100g^-1；鼻咽癌放疗后组（14例）BF、PEI、TTP、BV值分别为（25．2±7．0）ml·100g^-1·min^-1、（19．8±5．9）HU、（22．6±4．3）s、（6．1±2．4）ml·100g^-1，三组各灌注值差异有统计学意义（P值均〈0．01）；相关分析显示，鼻咽癌组（29例）中TNM分期（其中Ⅰ期3例，Ⅱ期9例，Ⅲ期10例，Ⅳ期7例）与PEI和BV存在相关性（r值分别为0．48和0．50），与BF和TTP无明显相关性（r值分别为0．23和0．22）；16例鼻咽癌MVD为（30．8±12．6）个／高倍镜视野，与其BF（51．4±17．0）ml·100g^-1·min^-1、PEI（33．2±9．6）HU和TTP（16．3±4．1）8存在相关性（r值分别为0．85、0．60和0．78），与BV（13．2±5．6）ml·100g^-1弱相关（r=0．48）。结论鼻咽癌有着特征的CT灌注表现，多层螺旋CT灌注成像的灌注值可以反映鼻咽癌微血管密度特征，PEI和BV值与鼻咽癌的TNM分期存在一定的相关性。     

Short term correlates of the Neuro Emotional Technique for cancer-related traumatic stress symptoms: A pilot case series

Introduction As many as one quarter of all cancer survivors report traumatic stress symptoms from cancer-related experiences. While the majority of these patients do not meet the criteria for posttraumatic stress disorder (PTSD), there is growing evidence that subsyndromal symptoms can significantly contribute to functional impairment and negative health outcomes. Treatment options for the hallmark symptoms of traumatic stress—unpleasant, intrusive thoughts and avoidant behaviors—have not been well investigated for the cancer survivorship population. Materials and methods Seven female cancer survivors with traumatic stress symptoms from cancer-related experiences and no other major psychopathology, were enrolled to receive three sessions of Neuro-Emotional Technique (NET), a brief, targeted treatment that combines traditional desensitization principles with complementary modalities. Results Psychological outcome measures (Impact of Event Scale (IES) and Subjective Units of Distress (SUD) and physiological measures (Heart Rate (HR) and Skin Conductance Level (SCL) demonstrated the following changes: 71% on IES, 88% SUD, 74% on HR, and 65% on SCL following the intervention. Statistically significant changes were observed for all four parameters, and effect size g for proportion improved were 0.50 each for IES, SUD, and HR, and 0.20 for SCL. Conclusions These cases suggest feasibility of the NET intervention for cancer-related traumatic stress and the potential for change in symptoms and physiological reactivity. Further investigation is needed to determine the specific and long-term effects of such an approach. Implications for cancer survivors Traumatic stress from cancer-related experiences might represent a constellation of symptoms that are amenable to brief, targeted interventions.

Identifying patients at risk for,and treatment of major psychiatric complications of cancer

A critically important aspect of supportive care in cancer is the prompt recognition and effective treatment of psychiatric complications. Psychiatric disorders such as depression, anxiety and delirium occur in a signifcant percentage of cancer patients, particularly as disease advances and as cancer treatments become more aggressive. This paper reviews factors that can be utilized to identify patients who are at increased risk for developing psychiatric complications, such as those with advanced disease, certain cancer treatments, uncontrolled physical symptoms, functional limitations, lack of social support, and past history of psychiatric disorder. Methods of diagnostic assessment and strategies for managing depression, anxiety, delirium and suicidal ideation are also reviewed.Presented as an invited lecture at the 6th International Symposium: Supportive Care in Cancer, New Orleans, La., USA, 2–5 March 1994

A daily process design study of attentional pain control strategies in the self-management of cancer pain.

This study investigated the use of attentional control strategies in the self-management of pain using daily process design methodology. Twenty six cancer patients with pain completed diaries 3 times daily for 10 days. Diaries incorporated measures of pain intensity, affect, coping, coping efficacy, and the novelty and predictability of pain, and participants completed a cross-sectional measure of catastrophizing. At the across-person level, focusing on pain was associated with increased negative affect, and the use of pain focusing strategies was positively correlated with experiencing pain that was novel in its location or quality. Distractions that were interesting, important and pleasant were positively correlated with positive affect, perceptions of control over pain and ability to decrease pain. Over-prediction of pain was positively correlated with catastrophizing, and negatively correlated with perceptions of control over and ability to decrease pain. The within-person analysis (ARIMA modelling) showed that catastrophizing moderated the effects of pain focusing strategies, novel pain and over-predictions of pain. Meta-analysis of the ARIMA models revealed that the within-person effects of using attentional strategies did not generalize across the sample. These findings indicated that the effects of distraction strategies are influenced by their motivational-affective significance rather than the frequency with which they are used, and provided further evidence that the threat value of pain influences the way in which people cope with their pain. Theoretical and clinical implications are discussed.
