Neuropsychological Sequelae of Non-Central Nervous System Cancer and Cancer Therapy

Cancer patients report numerous adverse symptoms associated with their disease and treatment including cognitive dysfunction, fatigue, and affective distress. Cognitive dysfunction is ubiquitous in patients with primary central nervous system (CNS) cancer and recent evidence has documented similar deficits in patients with non-CNS cancer as well. Both the cancer itself and treatments including chemotherapy, biological response modifiers, and hormonal therapies have been demonstrated to adversely impact cognitive and neurobehavioral function. Neuroimaging and neurophysiological investigations have likewise revealed alterations in brain function that are helping to account for the nature of these cognitive disorders. Similarly, preclinical animal research is assisting to identify the pathophysiological mechanisms that underlie treatment-related neurotoxicities. The coalescence of multidisciplinary clinical and research efforts hold promise for the development of interventions that may offer neuroprotection in addition to currently available symptomatic therapies and cognitive rehabilitation techniques.     

Religiosity and Cancer Screening

Churches have been suggested as avenues to reach African-American populations with messages about health because of their strong participation in church activities. Membership in several religious denominations has been associated with healthy lifestyle practices that are associated with lower cancer-incidence rates and better coping strategies among cancer patients. Among African-American women, however, belief in God as their doctor might preempt seeking treatment for cancer. The goal of the present study was to examine the influence of church participation and religious beliefs on the utilization of breast and cervical cancer screening among low-income, predominantly African-American women. A cohort consisting of 290 women was surveyed at baseline and one year later to determine the association between screening rates in the past year and measures of religiosity. The majority of women were members of a church (88%), with fairly regular church attendance (51% reported weekly attendance), and strong beliefs regarding God's influence on their health (e.g. 88% agreed that God was their doctor). Church attendance was the only religious variable related to screening frequency in univariate analyses, with those reporting attending church 1–3 times per month more likely to receive mammography screening (p = .013). Churches can provide avenues to reach African-American women about cancer screening; strong religious beliefs do not, however, appear to keep women from receiving regular screening exams.

Cancer Worry,Perceived Risk and Cancer Screening in First-Degree Relatives of Patients with Familial Gastric Cancer

Currently, there is a lack of evidence evaluating the psychological impact of cancer-related risk perception and worry in individuals at high risk for gastric cancer. We examined the relationships between perceived risk, cancer worry and screening behaviors among first-degree relatives (FDRs) of patients with familial gastric cancer. FDRs of patients diagnosed with familial gastric cancer with a non-informative genetic analysis were identified and contacted. Participants completed a telephone interview that assessed socio-demographic information, cancer risk perception, cancer worry, impact of worry on daily functioning, and screening behaviors. Twenty-five FDRs completed the telephone interview. Participants reported high levels of comparative and absolute cancer risk perception, with an average perceived lifetime risk of 54 %. On the other hand, cancer-related worry scores were low, with a significant minority (12 %) experiencing high levels of worry. Study participants exhibited high levels of confidence (median = 70 %) in the effectiveness of screening at detecting a curable cancer. Participants that had undergone screening in the past showed significantly lower levels of cancer-related worry compared to those that had never undergone screening. In conclusion, individuals at high-risk for gastric cancer perceived a very high personal risk of cancer, but reported low levels of cancer worry. This paradoxical result may be attributed to participants’ high levels of confidence in the effectiveness of screening. These findings highlight the importance for clinicians to discuss realistic risk appraisals and expectations towards screening with unaffected members of families at risk for gastric cancer, in an effort to help mitigate anxiety and help with coping.

Cancer Recovery and the Spirit

The present study addresses the definition and exploration of the existential and spiritual experience of persons who had spontaneously remitted or made a remarkable recovery from cancer. Spontaneous remitters had experienced a remission without having allopathic treatment which could account for the cancer regression. Those with remarkable recoveries may have had treatment, but had been given a prognosis of less than a 20% chance of survival in a specific number of months or years, and had survived at least five years past this time. The narratives of the ten participants indicated that cancer proved to be a wake-up call propelling them into unprecedented existential and spiritual growth. Nine of the participants reported that they had healed not only at physical, but also at emotional and spiritual levels. Most described a new and intensely numinous relationship with the divine and with the unity of all beings which was not religiously oriented. Nine out of ten participants felt that cancer had been a gift.

膀胱癌与尿流改道治疗策略

膀胱肿瘤是我国泌尿外科最常见的肿瘤,其中尿路上皮占95％。浸润性膀胱癌生物学行为高度恶性,治疗的主要方法是根治性膀胱切除术加盆腔淋巴结清扫术加尿流改道术。其被认为是标准的治疗方法。由于全膀胱切除术及尿流改道术常给患者带来生活质量的下降及精神上的压力,使患者很难接受这种手术。本文着重分析了患者的个体化治疗,应用辩证思维方...     

代谢综合征与乳腺癌

研究显示,代谢综合征可增加女性乳腺癌的患病风险,在绝经后妇女中表现更明显。这种作用可能通过胰岛素抵抗影响雌激素和性激素结合球蛋白水平、高胰岛素血症的直接或间接作用以及脂肪因子水平异常等机制实现。因此,对于我国乳腺癌发病率可能随代谢综合征人群不断扩大而上升的趋势应予以足够重视。

Cancer Victim Identity for Individuals with Histories of Cancer and Childhood Sexual Abuse

Identifying as a ‘cancer victim’ has been linked to adverse psychosocial sequelae in individuals who have been diagnosed with cancer. Being a childhood sexual abuse (CSA) survivor may predispose individuals towards a “victim” identity in general. The aim of this study was to determine the prevalence of identifying as a ‘cancer victim’ among CSA survivors who were diagnosed with cancer as adults, and to explore psychological factors associated with identification as a cancer victim. 105 adults reporting both a history of CSA and of having been diagnosed with cancer as an adult were recruited through Amazon Mechanical Turk. Variables assessed included CSA severity, abuse-related powerlessness, general mastery, and cancer victim identity. Fifty-one percent of the sample endorsed a cancer victim identity. Path analysis revealed that abuse-related powerlessness was related to decreased feelings of general mastery, which was in turn associated with cancer victim identification (x ² = .12, DF = 1, p < .73; RMSEA = .00; SRMR = .01: Bentler CFI = 1.0). From a clinical perspective, the results suggest that increasing general mastery in CSA survivors in the cancer setting may be an important mechanism for attenuating the risk for developing a cancer victim identity and, presumably, for downstream adverse psychosocial sequelae.
