Long-term positive psychological outcomes in an Australian pancreatic cancer screening program

The role of endoscopic ultrasound in the detection of pancreatic lesions in high-risk individuals

Individuals at high risk of developing pancreatic ductal adenocarcinoma are eligible for surveillance within research programs. These programs employ periodic imaging in the form of magnetic resonance imaging/magnetic resonance cholangiopancreatography or endoscopic ultrasound for the detection of early cancer or high-grade precursor lesions. This narrative review discusses the role of endoscopic ultrasound within these surveillance programs. It details its overall strengths and limitations, yield, burden on patients, and how it compares to magnetic resonance imaging. Finally, recommendations are given when and how to incorporate endoscopic ultrasound in the surveillance of high-risk individuals.

Familial pancreatic cancer: a case study and review of the psychosocial effects of diagnoses on families

BACKGROUND

Familial pancreatic cancer touches families through a genetic susceptibility to developing this neoplasia. Genetic susceptibility is assessed via family history, genetic testing, or both. Individuals with two or more first-degree relatives or three or more relatives of any degree diagnosed with pancreatic cancer are considered at elevated risk. Following a diagnosis of familial pancreatic cancer, patients and families face uncertainty and anxiety about the future. Psychosocial effects of a pancreatic cancer diagnosis on families include fear, concerns about personal health, and how lifestyle may impact the risk of developing pancreatic cancer.

CASE PRESENTATION

A 66-year-old male was diagnosed with pancreatic ductal adenocarcinoma stage IIB, T3, N1, M0. A genetic referral was made due to a history of multiple cases of pancreatic cancer within the patient's family. Genetic testing revealed the patient had a pathogenic variant in the ATM gene that is associated with an increased risk for pancreatic cancer development. The patient's one adult child was offered testing due to the autosomal dominant pattern of inheritance for this variant. The adult child was found to have the same pathogenic variant. She expressed fear for her future and her child's future health and longevity. Discussing a case study allows us to capture the multi-faceted relationship between the disease, the affected individuals, and their families. Examining the psychosocial stresses and concerns when there is a pancreatic cancer diagnosis in the family is essential to provide holistic care to patients and families.

CONCLUSIONS

The psychosocial effects of FPC may be overwhelming for patients and families. Healthcare providers can offer education, support, and referrals to appropriate services to help families cope through stages of evaluation, diagnosis, and treatment of FPC.

Health-related quality of life and anxiety levels among patients under surveillance for intraductal papillary mucinous neoplasm

BACKGROUND

Because of the premalignant nature of intraductal papillary mucinous neoplasms (IPMNs), patients should undergo surveillance as long as they remain fit for surgery. This surveillance, with imaging and laboratory tests every 6 to 12 months, is expensive and may psychologically burden patients. This study aimed to determine the effects of IPMN surveillance on patients´ health-related quality of life (HRQoL) and anxiety levels.

METHODS

We included a random subgroup of all IPMN patients undergoing a follow-up check-up at Helsinki University Hospital (HUH) between August 2017 and November 2018. Patients were asked to complete the 15D HRQoL and state-trait anxiety inventory (STAI) questionnaires just before and three months after an IPMN control.

RESULTS

Among 899 patients in IPMN follow-up, 232 participated. The 15D HRQoL results showed differences in some IPMN patients' 15 analyzed dimensions compared to a sex- and age-standardized general population cohort, but the clinical relevance of these differences appear doubtful. We detected no significant difference in the anxiety levels determined using the STAI questionnaires before or three months after the IPMN control.

CONCLUSION

Surveillance should be less harmful than the risk of disease. Among our patients, the recommended IPMN follow-up carried minimal negative impact on patients' HRQoL or anxiety levels. This result is important, because the number of patients under IPMN surveillance is rapidly increasing and the cancer risk among the majority of these patients remains small.

TRIAL REGISTRATION

The Surgical Ethics Committee of Helsinki University Hospital approved this study (Dnro HUS 475/2017) and it was registered at ClinicalTrials.gov (NCT03131076) before patient enrollment began.

The half-painted picture: Reviewing the mental health impacts of cancer screening

Cancer screening is recommended for select cancers worldwide. Cancer screening has become increasingly effective and accessible and often increases overall survival. However, the mental health effects of cancer screening, such as its impact on depression, anxiety, and post-traumatic stress disorder, are largely unknown. Conflicting available literature indicates the negative, neutral, and positive mental health effects of cancer screening across cancer types. There are a limited number of randomized controlled trials measuring the mental health effects of cancer screening. Overall, the more negative and life-threatening the screening results, the greater the mental health effects. Screening for cancer without a known precursor, for example, due to family history, can have positive impacts such as decreased worry and increased quality of life. However, receiving a cancer diagnosis often has negative mental effects that increase with the life-threatening potential of malignancy. In this study, we review the existing literature and provide recommendations for future research to determine if and when cancer screening is the best practice.

Pancreatic Cancer: Pathogenesis, Screening, Diagnosis, and Treatment

Pancreatic ductal adenocarcinoma (PDAC) is a clinically challenging cancer, due to both its late stage at diagnosis and its resistance to chemotherapy. However, recent advances in our understanding of the biology of PDAC have revealed new opportunities for early detection and targeted therapy of PDAC. In this review, we discuss the pathogenesis of PDAC, including molecular alterations in tumor cells, cellular alterations in the tumor microenvironment, and population-level risk factors. We review the current status of surveillance and early detection of PDAC, including populations at high risk and screening approaches. We outline the diagnostic approach to PDAC and highlight key treatment considerations, including how therapeutic approaches change with disease stage and targetable subtypes of PDAC. Recent years have seen significant improvements in our approaches to detect and treat PDAC, but large-scale, coordinated efforts will be needed to maximize the clinical impact for patients and improve overall survival.

High signal intensity on diffusion-weighted magnetic resonance images is a useful finding for detecting early-stage pancreatic cancer

Purpose

Early detection of pancreatic ductal adenocarcinoma (PDAC) may improve the prognosis. We evaluated novel imaging findings that may contribute to early detection.

Methods

This single-center, retrospective study enrolled 37 patients with a localized main pancreatic duct (MPD) stricture and no obvious pancreatic mass. All patients underwent endoscopic retrograde cholangiopancreatography and brush sampling with cytology and serial pancreatic juice aspiration cytologic examination via endoscopic naso-pancreatic drainage. Patients with cytology-confirmed malignancy underwent surgical resection. The remaining patients were followed by contrast-enhanced computed tomography (CECT), magnetic resonance imaging (MRI), and endoscopic retrograde cholangiopancreatography.

Results

Twenty patients had confirmed malignancy (cancer group) and 17 did not (non-cancer group). Age, MPD stricture location, and PDAC risk factors were similar, but the sex predominance and symptom rate differed between the two groups. In the cancer group, 17 patients were diagnosed by cytology and three by clinical symptoms. CECT, MRI, and endoscopic ultrasonography (EUS) revealed no solid tumors in either group. CECT revealed no significant differences between groups. Diffusion-weighted MRI revealed significant differences in the signal intensity between groups. EUS detected indistinct and small hypoechoic areas in 70% and 41.2% of patients in the cancer and non-cancer groups, respectively. In the cancer group, 11 were diagnosed with cancer at the first indication, and nine were diagnosed at follow-up; the prognosis did not differ between these two subgroups.ss

Conclusions

High signal intensity in diffusion-weighted MRI may be useful for detecting early-stage PDAC and may be an indication for surgical resection even without pathologic confirmation.

Clinical trial registration

The study was a registered at the University Hospital Medical Information Network (UMIN000039623).

Outcomes of endoscopic ultrasound as a one-off pancreatic cancer screening tool for 122 high- and moderate-risk patients

Background and Aim

Pancreatic cancer (PC) carries a poor prognosis and is often detected at later stages. Screening programs for moderate- and high-risk people are still under debate. We present the results from a prospective study on endoscopic ultrasound (EUS) as a one-off screening tool for pancreatic cancer screening.

Methods

Asymptomatic patients with moderate- or high-risk of PC were invited to participate. Moderate risk consisted of one first-degree and at least one second-degree relative with PC and no PC-associated genetic mutations. High risk consisted of >1 first-degree relatives with PC or PC-associated mutations (i.e. BRCA2, Lynch Syndrome, Familial Atypical Multiple Mole Melanoma Syndrome, STK11, or PALB2). All included patients had genetic counseling and a screening EUS done. Primary outcome was the detection of PC on EUS. Secondary outcomes assessed the evolution of psychological symptoms based on the Impact of Events Scale (IES) and Personal Consequences Questionnaire (PCQ) before and after the screening took place.

Results

A total of 122 patients had a screening EUS performed between 2013 and 2019; 60 were male, 55.8 years was the mean age, 78 were at high risk for PC, and 25 had PC-associated mutations. No pancreatic cancers were identified at the one-off EUS screening. Overall, patients' IES/PCQ scores did not change after screening and feedback of no malignancy, with the exception of females (less concerned about PC after screening EUS).

Conclusions

EUS did not detect any PCs in either a moderate- or high-risk population as a one-off screening method. The EUS procedure and genetic counseling improved psychological symptoms for the female subset of this population.

The emotional impact of surveillance programs for pancreatic cancer on high-risk individuals: A prospective analysis

OBJECTIVE

Literature shows that emotional status can influence participation in screening/surveillance programs, and that screening/surveillance programs may alter the psychological well-being of subjects examined. This study aims to assess if participating in a surveillance program for pancreatic cancer early detection is associated with abnormal levels of psychological distress in high-risk individuals (HRIs), compared to the general population.

METHODS

Fifty-four HRIs participating in a magnetic resonance cholangiopancreatography (MRCP)-based surveillance program completed several psychological assessment questionnaires, investigating global functioning, self-efficacy, perceived stress, coping abilities, and social support. The questionnaires were administered by a clinical psychologist after the MRCP but before the subjects were informed about the results of the scans. The HRIs were subjects with strong familiarity of pancreatic cancer and/or carriers of known genetic mutations related to cancer susceptibility. The psychological assessment was made at the time of the first examination.

RESULTS

The population was characterized by an overall good psychological status. Scoring of our sample was comparable to the general population norms. The HRIs showed decent global functioning, high self-efficacy levels, low perceived stress in the last month prior to examination, efficient emotion-focused coping strategies, and an adequate social support system. The younger subjects' subpopulation only revealed higher levels of stress.

CONCLUSIONS

From a psychological point of view, an MRCP-based pancreatic cancer annual surveillance seemed not to influence the HRIs' psychological well-being, unless in young people. Further studies are needed to better establish if there are any changes in distress levels over time and how emotional status influences participation in surveillance programs.

Patient-reported burden of intensified surveillance and surgery in high-risk individuals under pancreatic cancer surveillance

In high-risk individuals participating in a pancreatic cancer surveillance program, worrisome features warrant for intensified surveillance or, occasionally, surgery. Our objectives were to determine the patient-reported burden of intensified surveillance and/or surgery, and to assess post-operative quality of life and opinion of surgery. Participants in our pancreatic cancer surveillance program completed questionnaires including the Cancer Worry Scale (CWS) and the Hospital Anxiety and Depression Scale (HADS). For individuals who underwent intensified surveillance, questionnaires before, during, and ≥ 3 weeks after were analyzed. In addition, subjects who underwent intensified surveillance in the past 3 years or underwent surgery at any time, were invited for an interview, that included the Short-Form 12 (SF-12). A total of 31 high-risk individuals were studied. During the intensified surveillance period, median CWS scores were higher (14, IQR 7), as compared to before (12, IQR 9, P = 0.007) and after (11, IQR 7, P = 0.014), but eventually returned back to baseline (P = 0.823). Median HADS scores were low: 5 (IQR 6) for anxiety and 3 (IQR 5) for depression, and they were unaffected by the intensified surveillance period. Of the 10 operated patients, 1 (10%) developed diabetes and 7 (70%) pancreatic exocrine insufficiency. The interviews yielded median quality-of-life scores comparable to the general population. Also, after surgery, patients’ attitudes towards surveillance were unchanged (5/10, 50%) or became more positive (4/10, 40%). Although patients were aware of the (sometimes benign) pathological outcome, when asked if surgery had been justified, only 20% (2/10) disagreed, and all would again have chosen to undergo surgery. In conclusion, in individuals at high risk for pancreatic cancer, intensified surveillance temporarily increased cancer worries, without affecting general anxiety or depression. Although pancreatic surgery led to substantial co-morbidity, quality of life was similar to the general population, and surgery did not negatively affect the attitude towards surveillance.
