Granulocyte colony-stimulating factor-producing squamous cell carcinoma of the tongue exhibiting characteristic fluorine-18 deoxyglucose accumulation on positron emission tomography–computed tomography: A case report

BACKGROUND Granulocyte colony-stimulating factor(G-CSF)is a cytokine produced in inflammatory environments that induces differentiation and proliferation of neutrophils in bone marrow.We report a rare case of aggressive G-CSFproducing squamous cell carcinoma of the tongue exhibiting fluorine-18 deoxyglucose(FDG)accumulation in primary lesion,metastatic lymph nodes,spleen,and bone marrow on positron emission tomography–computed tomography(PET/CT).CASE SUMMARY We report a 58-year-old female with a rapid enlarged lingual mass with partial necrosis.Blood test results from the initial examination revealed a leukocyte count of 21380/μL.On PET/CT,extensive FDG accumulation was observed in the tongue and bilateral cervical lymph nodes,with elevated FDG accumulation in the spleen and bone marrow although no distant metastases were observed.We performed partial glossectomy and bilateral neck dissection.Immunohistochemical staining with G-CSF antibodies on biopsy specimen and resected samples revealed that both specimens were G-CSF positive.This is a rare case of G-CSF producing tongue carcinoma with elevated FDG accumulation in the spleen and bone marrow.CONCLUSION In patients with the tongue cancer and hyperleukocytosis,where FDG accumulations in the spleen and bone marrow are observed using PET/CT and when these accumulations are not caused by metastasis,G-CSF-producing tumors,with associated poor prognosis,should be considered.     

Prognostic factors for overall survival in prostate cancer patients with different site-specific visceral metastases: A study of 1358patients

BACKGROUND Distant metastasis,particularly visceral metastasis(VM),represents an important negative prognostic factor for prostate cancer(PCa)patients.However,due to the lower rate of occurrence of VM,studies on these patients are relatively rare.Consequently,studies focusing on prognostic factors associated with PCa patients with VM are highly desirable.AIM To investigate the prognostic factors for overall survival(OS)in PCa patients with lung,brain,and liver metastases,respectively,and evaluate the impact of site-specific and number-specific VM on OS.METHODS Data on PCa patients with VM were extracted from the Surveillance,Epidemiology,and End Results database between 2010 and 2015.Univariate and multivariate Cox regression analyses were used to analyze the association between clinicopathological characteristics and survival of patients with different site-specific VM.Kaplan-Meier analyses and Log-rank tests were performed to analyze the differences among the groups.RESULTS A total of 1358 PCa patients with site-specific VM were identified from 2010 to 2015.Older age(>70 years)(P<0.001),higher stage(T3/T4)(P=0.004),and higher Gleason score(>8)(P<0.001)were found to be significant independent prognostic factors associated with poor OS in PCa patients with lung metastases.Higher stage(T3/T4)(P=0.047)was noted to be the only independent risk factor affecting OS in PCa patients with brain metastases.Older age(>70 years)(P=0.010)and higher Gleason score(>8)(P=0.001)were associated with shorter OS in PCa patients with liver metastases.PCa patients with isolated lung metastases exhibited significantly better survival outcomes compared with PCa patients with other single sites of VM(P<0.001).PCa patients with a single site of VM exhibited a superior OS compared with PCa patients with multiple sites of VM(P<0.001).CONCLUSION This is the first Surveillance,Epidemiology,and End Results-based study to determine prognostic factors affecting OS in PCa patients with different sitespecific VM.Clinical assessments of these crucial prognostic factors become necessary before establishing a treatment strategy for these patients with metastatic PCa.     

Correlation of neuron specific enolase serum concentration and prognosis in patients with severe head injury

AIM:To eluciate the role of neuron specific enolase(NSE) in predicting prognosis after severe head injury.METHODS:30 patients with severe head injury were involved into this study,ranging from 26 to 64 years old.Concentration of NSE in serum was measured in all cases within 12 hours after head injury.And prognosis of all patients were evaluated by GOS.RESULTS:The concentration of NSE in serum of both groups,with good or poor outcome,were higher than normal group.The concentrations within 12 hours after head injuries had a cose relationship with the prognosis.As a serum marker to assess the prognosis,NSE had high positive prediction ratio.CONCLUSION:The finding suggested that NSE may be a promising predictor for assessing the prognosis after severe head injury.     

Berson, Yalow, and the JCI: the agony and the ecstasy

The isolation of insulin in 1921 by Banting, Best, Collip, and Macleod stands as one of the most dramatic stories in modern medical investigation. Only two years passed between the initial experiments in dogs to widespread human application to the awarding of the Nobel Prize in 1923. Insulin-related research has also served as a focus, at least in part, for the work of three other Nobel Prize recipients: determination of the chemical structure of insulin by Frederick Sanger in 1958; determination of the three-dimensional structures of insulin and vitamin B12 by Dorothy Hodgkin in 1964; and finally, the development of immunoassay by Solomon Berson and Rosalyn Yalow in 1959-1960, which led to a Nobel Prize for Yalow in 1977 (five years after the untimely death of Berson). The history of Yalow and Berson's discovery and its impact on the field is an illustration of the adage that every story has two sides.
