The association of ectopic craniopharyngioma in the fourth ventricle with familial adenomatous polyposis: illustrative case

[BACKGROUND] Craniopharyngioma (CP) often arises in the sellar and suprasellar areas; ectopic CP in the posterior fossa is rare. Familial adenomatous polyposis (FAP) is a genetic disorder involving the formation of numerous adenomatous polyps in the gastrointestinal tract, and it is associated with other extraintestinal manifestations. [OBSERVATIONS] The authors reported the case of a 63-year-old woman with FAP who presented with headache and harbored a growing mass in the fourth ventricle. Magnetic resonance imaging (MRI) findings revealed a well-circumscribed mass with high intensity on T1-weighted images and low intensity on T2-weighted images and exhibited no contrast enhancement. Gross total resection was performed and histopathology revealed an adamantinomatous CP (aCP). The authors also reviewed the previous reports of ectopic CP in the posterior fossa and found a high percentage of FAP cases among the ectopic CP group, thus suggesting a possible association between the two diseases. [LESSONS] An ectopic CP may be reasonably included in the differential diagnosis in patients with FAP who present with well-circumscribed tumors in the posterior fossa

Negative recollections regarding doctor–patient interactions among men receiving a prostate cancer diagnosis: a qualitative study of patient experiences in Japan

Objectives: To explore the negative recollections of prostate cancer patients regarding the attitudes and language used by the doctors in delivering their diagnoses in Japan, in order to improve patient-centred communication. Design and setting: This is a qualitative secondary analysis of the prostate cancer narrative data from the Database of Individual Patients’ Experiences-Japan archives. A thematic analysis was conducted regarding negative recollections of doctors’ words/attitudes when delivering a cancer diagnosis. Recruitment was based on maximum variation sampling. Participants were recruited from medical institutions, patient associations and through media advertisements. Participants: Men with a diagnosis of prostate cancer (n=51). Findings: Of the 51 participants, 17 had negative recollections of the doctors’ words/attitudes during the delivery of the cancer diagnosis. After thematic analysis, 11 categories emerged: ‘Surprised by the abrupt disclosure of the diagnosis’, ‘Displeased by the direct disclosure of the diagnosis to the patient in the absence of family members’, ‘Unable to accept the doctor’s negative words in the explanations’, ‘Unable to understand the doctor’s technical jargon’, ‘Distrust due to failure in diagnosis based on previous examinations’, ‘Aggrieved at the doctor’s unwillingness to allow questions’, ‘Dissatisfied with explanations involving facts only’, ‘Indignant over the unexpected disclosure of life expectancy’, ‘Unable to accept the doctor’s blame for the delay in the initial hospital visit’, ‘Uncomfortable with the usage of inappropriate metaphors’ and ‘Pessimistic thoughts despite optimistic explanations’. Conclusions: It is clear that patients have recollections of a variety of negative experiences regarding the words/attitudes of their doctors at the time they received their prostate cancer diagnosis. Thus, the use of narrative data would facilitate the appropriate application of commonly used guidelines for the delivery of cancer diagnoses tailored to individual patients in clinical practice

Familial pancreatic cancer: Concept, management and issues

Familial pancreatic cancer (FPC) is broadly defined as two first-degree-relatives with pancreatic cancer (PC) and accounts for 4%-10% of PC. Several genetic syndromes, including Peutz-Jeghers syndrome, hereditary pancreatitis, hereditary breast-ovarian cancer syndrome (HBOC), Lynch syndrome, and familial adenomatous polyposis (FAP), also have increased risks of PC, but the narrowest definition of FPC excludes these known syndromes. When compared with other familial tumors, proven genetic alterations are limited to a small proportion ( Caucasian) and a younger onset are common also in FPC. In European countries, “anticipation” is reported in FPC families, as with other hereditary syndromes; a trend toward younger age and worse prognosis is recognized in the late years. The resected pancreases of FPC kindred often show multiple pancreatic intraepithelial neoplasia (PanIN) foci, with various K-ras mutations, similar to colorectal polyposis seen in the FAP patients. As with HBOC patients, a patient who is a BRCA mutation carrier with unresectable pancreatic cancer (accounting for 0%-19% of FPC patients) demonstrated better outcome following platinum and Poly (ADP-ribose) polymerase inhibitor treatment. Western countries have established FPC registries since the 1990s and several surveillance projects for high-risk individuals are now ongoing to detect early PCs. Improvement in lifestyle habits, including non-smoking, is recommended for individuals at risk. In Japan, the FPC study group was initiated in 2013 and the Japanese FPC registry was established in 2014 by the Japan Pancreas Society
