A total of 122 specimens of colorectal cancer were re-assessed in relation to the reporting of invasive growth pattern (expanding vs. infiltrating) and presence or absence of peritumoral lymphocytic infiltrate as used in the Jass prognostic classification. Jass agreed with 69% of cases reported as infiltrating and 90% of reported as expanding. This parameter was distributed similarly amongst Dukes B and C cases in the original assessment (P = 0.27), whereas in the reviewed data infiltrating cases were more likely to be staged as Dukes C (P = 0.04). Jass agreed with 44% of lymphocyte present and 94% of lymphocyte absent assessments. The original lymphocyte assessments showed no significant differences in distribution between Dukes A and B cases (P = 0.12) or B and C cases (P = 0.75), whereas the reviewed data showed significant differences for A vs. B (P = 0.015) and B vs. C cases (P = 0.0025). Criteria for assessment were circulated to eight observers who revisited 20 of the cases in which there was disagreement. Consensus agreement with Jass was achieved in nine of 10 cases for invasive growth pattern and seven of 10 cases for lymphocyte infiltration (with two being evenly split). Most observers showed at least fair levels of agreement with Jass and some achieved excellent levels of agreement. This study indicates that assessment of criteria used in the Jass prognostic system for colorectal cancer is less than optimal in routine practice, but is improved through the provision of simple guidelines.
Two patients presented with abdominal pain, recurrent vomiting, weight loss, and constipation secondary to intestinal pseudo-obstruction. Both patients had symptoms and signs of myasthenia gravis, acetylcholine receptor antibodies, and thymoma. In one patient inflammatory cell infiltrates and occasional degenerate neurons were found in the myenteric plexus. The gastrointestinal symptoms resolved during treatment with pyridostigmine. The close temporal relationship between the onset of the gastrointestinal symptoms and the detection of myasthenia gravis and thymoma suggests that intestinal pseudo-obstruction can be a paraneoplastic syndrome associated with thymoma.
Imatinib is a specific tyrosine kinase inhibitor which has been approved for the treatment of Philadelphia chromosome-positive chronic myeloid leukaemia and c-KIT (CD117)-positive gastrointestinal stromal tumours. It has been associated with hepatotoxicity ranging from abnormal liver function tests to acute liver failure along with chronic hepatitis B reactivation. We report the case of a patient who was started on adjuvant treatment with imatinib following resection of a primary gastrointestinal stromal cell tumour of jejunum and developed severe hepatotoxicity. There was no history of risk factors for liver disease, and a search for the underlying causes of hepatotoxicity was unremarkable. Imatinib was stopped and she was treated with steroids which resulted in dramatic improvement of liver function tests. Liver biopsy in this case was not performed because liver function tests improved following discontinuation of imatinib and treatment with steroids. Repeat imaging did not reveal any evidence of tumour recurrence.
Background:
Covid-19 vaccination has started in the majority of the countries at the global level. Cancer patients are at high risk for infection, serious illness, and death from COVID-19 and need vaccination guidance and support.
Guidance availability in the English language only is a major limit for recommendations’ delivery and their application in the world’s population and generates information inequalities across the different populations.
Methods:
Most of the available COVID-19 vaccination guidance for cancer patients was screened and scrutinized by the European Cancer Patients Coalition (ECPC) and an international oncology panel of 52 physicians from 33 countries.Results: A summary guidance was developed and provided in 28 languages in order to reach more than 70 percent of the global population.
Conclusion:
Language barrier and e-guidance availability in the native language are the most important barriers when communicating with patients. E-guidance availability in various native languages should be considered a major priority by international medical and health organizations that are communicating with patients at the global level.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
