Panic as a harbinger of pancreatic cancer

Pre-existing psychological disorders, diabetes, and pancreatic cancer: A population-based study of 38,952 Finns

BACKGROUND

It remains unclear how pre-existing depression, anxiety, and diabetes of different durations are associated with the risk of pancreatic cancer, its clinical characteristics, treatment modalities, and subsequent survival.

METHODS

From a register-based random sample of Finns residing in Finland at the end of the period 1987-2007, 6492 patients diagnosed with primary pancreatic cancer in 2000-2014, and 32 460 controls matched for birth cohort and sex, were identified. Pre-existing depression, anxiety, and diabetes were ascertained from the records of prescribed medication purchases. Information on pancreatic cancer outcomes was obtained from the Finnish cancer register. Data were analyzed using logistic and Cox regressions.

RESULTS

The risk of developing pancreatic cancer was found to be associated with long-term anxiety (treatment started 36 + months before the cancer diagnosis) (odds ratio (OR): 1.13, 95% confidence interval (95%CI): 1.04-1.22) and long-term diabetes (OR 1.72, 95%CI 1.55-1.90), as well as with new-onset (treatment started 0-24 months before the cancer diagnosis) depression (OR 1.59, 95%CI 1.34-1.88), anxiety (OR 1.76, 95%CI 1.50-2.07), and diabetes (OR 3.92, 95%CI 3.44-4.48). However, the effects of these new-onset conditions were driven by cases that began treatment within 3 months before the cancer diagnosis (concomitant period). Patients with long-term depression, anxiety and diabetes and those with new-onset anxiety had a higher risk of not receiving standard treatments. Lower survival was found for pancreatic cancer patients with new-onset depression (hazards ratio (HR) 1.38, 95%CI 1.16-1.64). Survival was not associated with pre-existing anxiety or diabetes.

CONCLUSIONS

The associations between pancreatic cancer risk and pre-existing depression and anxiety were mostly driven by concomitant effects. Individuals with diabetes, regardless of duration, should be closely monitored for pancreatic cancer. Pancreatic cancer patients with new-onset depression should be targeted to improve their survival.

Prodromal depression and anxiety are associated with worse treatment compliance and survival among patients with pancreatic cancer

OBJECTIVE

To determine the frequency of depression or anxiety preceding a diagnosis of pancreatic cancer (PC). Further, to examine the association of PC-associated depression or anxiety with treatment compliance and survival.

METHODS

856 patients with PC from a single institution were identified using International Classification of Diseases (ICD) codes. For each case, two non-cancer age- and sex-matched controls were included. Dates of depression or anxiety diagnosis identified using ICD codes were compared to the date of PC diagnosis. The medical record was queried to further explore psychiatric symptoms. Multivariable analyses were performed to examine if prediagnosis depression or anxiety was associated with receipt of treatment or survival.

RESULTS

A greater proportion of patients with PC experienced depression or anxiety in the year preceding diagnosis than the overall frequency in controls (4.6% vs. 2.6%, p = 0.005) based on ICD codes. Patients with PC exhibited signs of prodromal depression or anxiety based on ICD codes, clinical documentation of psychiatric symptoms, or initiation of new psychiatric medications more often than controls (20.7% vs. 6.7%, p < 0.001). Prediagnosis depression or anxiety was associated with a reduced likelihood of receiving chemotherapy (OR = 0.58, p = 0.04). There was an associated decrease in overall survival among patients with metastatic disease who experienced depression or anxiety before PC diagnosis (HR = 1.32, p = 0.04).

CONCLUSIONS

The frequency of depression or anxiety among patients with PC was higher than the general population. Prediagnosis psychiatric symptoms were associated with reduced chemotherapy utilization and worse overall survival. Thus, timely identification and treatment of these symptoms may improve outcomes.

Panic attacks and smoking cessation among cancer patients receiving smoking cessation treatment

OBJECTIVE

Little is known about factors associated with smoking cessation in cancer patients. This study examined the impact of panic attacks on smoking abstinence likelihood among cancer patients receiving tobacco cessation treatment.

METHOD

The relationship of panic attacks to 7-day point-prevalence abstinence at mid-treatment, end of treatment, and 6-month post-end of treatment were examined among cancer patients (N=2255 patients; 50.1% female; Mage=54.9, SD=11.0) who received counseling and pharmacotherapy for smoking cessation. Panic attack history indexed by two questions from the Patient Health Questionnaire (PHQ). Point-prevalence abstinence was assessed via the Timeline Follow-Back.

RESULTS

Cancer patients with a history of panic attacks, (n=493, 21.9%) relative to those without, were less likely to be abstinent at mid-treatment (OR=0.79, CI95%=0.64-0.98) and end of treatment (OR=0.72, CI95%=0.58-0.89). After adjusting for significant covariates, panic attack history remained predictive of decreased abstinence likelihood at end of treatment (OR =0.78, CI95%=0.62-0.99).

CONCLUSIONS

Panic attacks may be related to poorer cessation outcome during smoking treatment among cancer patients, and may be usefully assessed and targeted for intervention.

Mood and anxiety disorders as early manifestations of medical illness: a systematic review

BACKGROUND

Affective disturbances involving alterations of mood, anxiety and irritability may be early symptoms of medical illnesses. The aim of this paper was to provide a systematic review of the literature with qualitative data synthesis.

METHODS

MEDLINE, PsycINFO, EMBASE, Cochrane, and ISI Web of Science were systematically searched from inception to February 2014. Search terms were 'prodrome/early symptom', combined using the Boolean 'AND' operator with 'anxiety/depression/mania/hypomania/irritability/irritable mood/hostility', combined with the Boolean 'AND' operator with 'medical illness/medical disorder'. PRISMA guidelines were followed.

RESULTS

A total of 21 studies met the inclusion criteria and were analyzed. Depression was found to be the most common affective prodrome of medical disorders and was consistently reported in Cushing's syndrome, hypothyroidism, hyperparathyroidism, pancreatic and lung cancer, myocardial infarction, Wilson's disease, and AIDS. Mania, anxiety and irritability were less frequent.

CONCLUSIONS

Physicians may not pursue medical workup of cases that appear to be psychiatric in nature. They should be alerted that disturbances in mood, anxiety and irritability may antedate the appearance of a medical disorder.

Lifestyle Behaviours Add to the Armoury of Treatment Options for Panic Disorder: An Evidence-Based Reasoning

This article presents an evidence-based reasoning, focusing on evidence of an Occupational Therapy input to lifestyle behaviour influences on panic disorder that also provides potentially broader application across other mental health problems (MHP). The article begins from the premise that we are all different. It then follows through a sequence of questions, examining incrementally how MHPs are experienced and classified. It analyses the impact of individual sensitivity at different levels of analysis, from genetic and epigenetic individuality, through neurotransmitter and body system sensitivity. Examples are given demonstrating the evidence base behind the logical sequence of investigation. The paper considers the evidence of how everyday routine lifestyle behaviour impacts on occupational function at all levels, and how these behaviours link to individual sensitivity to influence the level of exposure required to elicit symptomatic responses. Occupational Therapists can help patients by adequately assessing individual sensitivity, and through promoting understanding and a sense of control over their own symptoms. It concludes that present clinical guidelines should be expanded to incorporate knowledge of individual sensitivities to environmental exposures and lifestyle behaviours at an early stage.

Screening for depression, sleep-related disturbances, and anxiety in patients with adenocarcinoma of the pancreas: a preliminary study

Purpose. Screening for depression, sleep-related disturbances, and anxiety in patients with diagnosed adenocarcinoma of the pancreas. Materials and Methods. Patients were evaluated at initial consultation and subsequent visits at the multidisciplinary pancreatic cancer clinic at our University Cancer Center. Cross-sectional and longitudinal psychosocial distress was assessed utilizing Personal Health Questionnaire 9 (PHQ9) to screen for depression and monitor symptoms, the Penn State Worry Questionnaire (PSWQ) for generalized anxiety, and the University of Michigan Sleep Questionnaire to monitor sleep symptoms. Results. Twenty-two patients diagnosed with pancreatic cancer participated during the 6-month pilot study with longitudinal followup for thirteen patients. In this study, mild-to-moderate depressive symptoms, anxiety, and potential sleep problems were common. The main finding of the study was 23% of the patients who were part of this pilot project screened positive for moderately severe major depressive symptoms, likely anxiety disorder or a potential sleep disorder during the study. One patient screened positive for moderately severe depressive symptoms in longitudinal followup. Conclusions. Depression, anxiety, and sleep problems are evident in patients with pancreatic cancer. Prospective, longitudinal studies, with larger groups of patients, are needed to determine if these comorbid symptoms impact outcome and clinical course.

Pancreatic cancer and depression: myth and truth

BACKGROUND

Various studies reported remarkable high incidence rates of depression in cancer patients compared with the general population. Pancreatic cancer is still one of the malignancies with the worst prognosis and therefore it seems quite logical that it is one of the malignancies with the highest incidence rates of major depression.However, what about the scientific background of this relationship? Is depression in patients suffering from pancreatic cancer just due to the confrontation with a life threatening disease and its somatic symptoms or is depression in this particular group of patients a feature of pancreatic cancer per se?

DISCUSSION

Several studies provide evidence of depression to precede the diagnosis of pancreatic cancer and some studies even blame it for its detrimental influence on survival. The immense impact of emotional distress on quality of life of cancer patients enhances the need for its early diagnosis and adequate treatment. Knowledge about underlying pathophysiological mechanisms is required to provide the optimal therapy.

SUMMARY

A review of the literature on this issue should reveal which are the facts and what is myth.
