Screening practices of cancer survivors and individuals whose family or friends had a cancer diagnoses-a nationally representative cross-sectional survey in Japan (INFORM Study 2020).

PURPOSE: We examined cancer screening practices and related beliefs in cancer survivors and individuals with family or close friends with a cancer diagnosis compared to individuals without the above cancer history for 5 population-based (gastric, colorectal, lung, breast, cervical) and 1 opportunistic (prostate) cancer screenings using nationally representative cross-sectional survey in Japan. METHODS: We analyzed 3269 data from 3605 respondents (response rate, 37.1%) and compared the screening beliefs and practices of cancer survivors (n = 391), individuals with family members (n = 1674), and close friends with a cancer diagnosis (n = 685) to those without any cancer history (n = 519). RESULTS: Being a cancer survivor was associated with screening for gastric (OR, 1.75; 95% CI, 1.04-2.95), colorectal (OR, 1.56; 95% CI, 1.03-2.36), and lung cancer (OR, 1.71; 95% CI, 1.10-2.66) but not breast, cervical cancer or PSA test. Having a family cancer diagnosis was associated with colorectal and lung cancer screening. Having friends with a cancer diagnosis was associated with PSA test. Cancer survivors and family members perceived themselves as being more susceptible and worried about getting cancer than individuals without any cancer history. Cancer survivors strongly believed screening can detect cancer and were more likely to undergo screening. Subgroup analysis indicated an interrelation between gastric and colorectal cancer screening among survivors. CONCLUSIONS: A cancer diagnosis in oneself or family or friend influences an individual's health-related belief and risk perception, which can increase the likelihood of cancer screening. IMPLICATIONS FOR CANCER SURVIVORS: Targeted and tailored communication strategies can increase awareness of cancer screening.

Eosinophilic granuloma with Splendore-Hoeppli material caused by Mannheimia granulomatis in a calf.

A large subcutaneous mass, formed on the left lower jaw of a 4-month-old Japanese Black male calf, was partially excised for histological and bacteriological examinations. Antibiotic treatment resulted in a good prognosis. Bacteria isolated from the excised material were characterized by weak hemolysis and positive reactions for catalase and oxidase, and were 99% identical to Mannheimia granulomatis strains. The presence of the leukotoxin gene product was demonstrated by polymerase chain reaction amplification. Histological examination showed that the excised material was composed of dense fibrous connective tissue with sparsely distributed eosinophilic granulomas or abscesses. These foci frequently contained Splendore-Hoeppli material with rod-shaped Gram-negative bacteria. Except for the absence of lymphangitis and the presence of basophils and mast cells, the histology of this lesion resembled that of lechiguana associated with coinfection of M. granulomatis and Dermatobia hominis. Leukotoxin was demonstrated by immunohistochemistry within Splendore-Hoeppli material and was judged to be responsible for its formation.
