Texture analysis was performed on axial DWI images, and five characteristic parameters including Angular Second Moment(ASM), Contrast, Correlation, Inverse Difference Moment(IDM), and Entropy were calculated. Independent sample t-test and Mann-Whitney U test were performed for intergroup comparison. Regression model was established by using Binary Logistic regression analysis, and receiver operating characteristic curve(ROC) analysis was carried out to evaluate the diagnostic efficiency. Results The texture features ASM, Contrast, Correlation and Entropy showed significant differences between the benign and malignant breast tumor groups(PASM= 0.014, Pcontrast= 0.019, Pcorrelation= 0.010, Pentropy= 0.007). The area under the ROC curve was 0.685, 0.681, 0.754, and 0.683 respectively for the positive texture variables mentioned above, and that for the combined variables(ASM, Contrast, and Entropy) was 0.802 in the model of Logistic regression. Binary Logistic regression analysis demonstrated that ASM, Contrast and Entropy were considered as thespecific imaging variables for the differential diagnosis of breast benign and malignant tumors.Conclusion The texture analysis of DWI may be a simple and effective tool in the differential diagnosis between breast benign and malignant tumors.展开更多

Design: A retrospective study of cases series. Setting: Salmaniya Medical Complex, Otorhinolaryngology Department, Kingdom of Bahrain. Methods: A retrospective study was carried out, between January 2009 and December 2018, for all patients diagnosed with parotid tumors at the Department of Otorhinolaryngology, Head and Neck Surgery at Salmaniya Medical Complex, Manama, Kingdom of Bahrain. Data collection was made from medical records, I-seha and laboratory information system (LIS). 87 patients underwent parotidectomy, of which 30 were excluded due to unsatisfactory diagnoses or missing data. The results of fine needle aspirations were analyzed and compared with the corresponding histopathologic diagnosis. Estimation of sensitivity, specificity, negative predictive value, positive predictive value and accuracy of FNA were calculated. Results: Among the 57 evaluated cases, four cases were further excluded from the final analysis due to unsatisfactory FNA results, therefore only 53 cases remained. The mean age of patients was 48.6 ± 17.2 years. A concordance with histopathology results was observed. 47 cases were diagnosed as benign and five cases were malignant, however, 1 case was diagnosed as malignant by FNA, but not in histopathology. The overall diagnostic accuracy was 98.1% and the prevalence of parotid malignancy was 9.4%. Sensitivity and specificity were 100% and 97.9%, respectively. Positive predictive value was 83.3% while negative predictive value was 100%. Conclusion: Fine needle aspiration is a highly sensitive and specific test in evaluating malignant parotid gland tumors. It is useful and accurate, especially when used hand by hand with the clinical assessment and radiological findings.展开更多

We compared the postoperative adverse events of pelvic tumor surgery and limb tumor surgery using a national inpatient database. Methods: We identified patients who underwent surgery for primary musculoskeletal malignant tumors of the pelvis or limbs between July and December in 2007- 2010 using the Japanese Diagnosis Procedure Combination inpatient database. We calculated the risk-adjusted odds ratio for the occurrence of postoperative complications following pelvic tumor surgery with reference to limb tumor surgery using a multivariable logistic regression analysis. Results: Of 3255 eligible patients, 3116 underwent limb tumor surgery and 139 underwent pelvic tumor surgery. In-hospital mortality was 0.6% and 0.7% and postoperative complication rates were 8.2% and 18.7%, respectively. The rate of blood transfusion and duration of anesthesia over 480 min were higher in the pelvic tumor group. Blood transfusion volume and duration of anesthesia were independently associated with worse outcomes, but there was no significant association between tumor location and occurrence of postoperative complications (odds ratio 1.18, 95% confidence interval 0.73 - 1.88, p = 0.502). Conclusions: Blood transfusion volume and duration of anesthesia were significant predictors of outcome. Our data demonstrate that the higher morbidity rate after pelvic tumor resection could result from the larger blood transfusion volume and longer anesthesia duration.展开更多

In some cases, it may mimic a glial lesion, making differential diagnosis challenging. The authors report two cases of giant tuberculoma in young patients aged 14 and 16. A literature review was conducted on these cases. Both patients underwent partial excision. Histology concluded tuberculoma. Anti-tubercular treatment was implemented. The evolution one year later was marked by the persistence of neurological disorders, although they had improved.展开更多

Methods A total of 170 patients with diagnosed cancer or suspicious cancer were enrolled in this study, and underwent ^18F-FDG PET. The standard uptake value (SUV) and diameter for each abnormal region in PET images were analyzed. All data were analyzed by SPSS 11.5. Results PET scan identified a primary cancer in 45.8% (11/24) patients. The sensitivity and specificity of PET scan in differentiating malignant lesions from benign ones were 78.8% (52/66) and 77.1% (27/35) respectively. Twenty-nine out of 68 (42.6%) lesions were detected earlier by PET than by computed tomography. The SHV of primary cancer was significantly higher than that of metastatic lymph nodes (5.84± 3.12 vs. 3.14± 2.24, P〈0.001). And SLIV of primary lung cancer was also significantly higher than that of metastatic lung cancer (6.30±3.01 vs. 2.86±2.37, P〈0.01).Conclusion ^18F-FDG PET plays a very important role in cancer diagnosis.展开更多

The overall diagnostic accuracy was 98.1% and the prevalence of parotid malignancy was 9.4%. Sensitivity and specificity were 100% and 97.9%, respectively. Positive predictive value was 83.3% while negative predictive value was 100%. Conclusion: Fine needle aspiration is a highly sensitive and specific test in evaluating malignant parotid gland tumors. It is useful and accurate, especially when used hand by hand with the clinical assessment and radiological findings.
文摘Introduction: Resection of malignant pelvic tumors has long been considered to be associated with higher postoperative mortality and morbidity than resection of malignant limb tumors. We compared the postoperative adverse events of pelvic tumor surgery and limb tumor surgery using a national inpatient database. Methods: We identified patients who underwent surgery for primary musculoskeletal malignant tumors of the pelvis or limbs between July and December in 2007- 2010 using the Japanese Diagnosis Procedure Combination inpatient database. We calculated the risk-adjusted odds ratio for the occurrence of postoperative complications following pelvic tumor surgery with reference to limb tumor surgery using a multivariable logistic regression analysis. Results: Of 3255 eligible patients, 3116 underwent limb tumor surgery and 139 underwent pelvic tumor surgery. In-hospital mortality was 0.6% and 0.7% and postoperative complication rates were 8.2% and 18.7%, respectively. The rate of blood transfusion and duration of anesthesia over 480 min were higher in the pelvic tumor group. Blood transfusion volume and duration of anesthesia were independently associated with worse outcomes, but there was no significant association between tumor location and occurrence of postoperative complications (odds ratio 1.18, 95% confidence interval 0.73 - 1.88, p = 0.502). Conclusions: Blood transfusion volume and duration of anesthesia were significant predictors of outcome. Our data demonstrate that the higher morbidity rate after pelvic tumor resection could result from the larger blood transfusion volume and longer anesthesia duration.

文摘BACKGROUND Multiple primary malignant tumors(MPMTs)was first described by Billroth as early as 1889,with the first report published by Warren and Gates in 1932.Since then,numerous cases have been reported.A literature review of 1104269 patients with cancer revealed that the incidence of MPMTs ranged from 0.73 to 11.7%.In recent years,however,there has been a significant upward trend in the incidence of this phenomenon,which may be associated with many different factors,including the advancement of modern diagnostic procedures facilitating the examination and diagnosis of more MPMTs,increased exposure to chemotherapy and radiotherapy that exacerbate the risk of new malignant tumors in patients with cancer,and prolonged survival of patients with cancer allowing sufficient time for the development of new primary cancers.AIM To analyze the incidence,clinical features,treatment factors,prevalence,and prognosis of patients with MPMTs in the gastrointestinal tract treated in a single center.Additionally,we analyzed the different tumor combinations,time interval between the occurrence of tumors,and staging.METHODS This retrospective cohort study analyzed 8059 patients with pathologically confirmed gastrointestinal malignant tumors treated at the Gansu Province Hospital in Lanzhou,Gansu,China between June 2011 and June 2020.Of these,85 patients had MPMTs.The clinical features,treatment factors,prevalence,and prognosis of this latter cohort were analyzed.RESULTS The incidence of MPMTs in patients with gastrointestinal malignant tumors was 1.05%(85/8059),including 83 double primary malignant tumors and two triple primary malignant tumors of which 57(67.06%)were synchronous MPMTs(SMPMTs)and 28(32.94%)were metachronous MPMTs(MMPMTs).The most frequent associations were found between the rectum colon cancers within the SMPMT category and the gastric-colon cancers within the MMPMT category.For the MMPMTs,the median interval was 53 months.The overall 1-,3-and 5-year survival rates from diagnosis of the first primary cancer were 91.36%,65.41%,and 45.97%,respectively;those from diagnosis of the second primary cancer were 67.90%,29.90%,and 17.37%,respectively.CONCLUSION MPMTs in the gastrointestinal tract have a high incidence and poor prognosis.Thus,it is necessary to perform both gastroscopy and colonoscopy in patients with gastrointestinal tumors.Multidisciplinary comprehensive diagnosis and treatment may improve the diagnosis rate and treatment efficiency of MPMTs.

文摘The coexistence of venous thromboembolism(VTE)within patients with cancer,known as cancer-associated thrombosis(CAT),stands as a prominent cause of mortality in this population.Over recent years,the incidence of VTE has demonstrated a steady increase across diverse tumor types,influenced by several factors such as patient management,tumor-specific risks,and treatment-related aspects.Furthermore,mutations in specific genes have been identified as potential contributors to increased CAT occurrence in particular cancer subtypes.We conducted an extensive review encompassing pivotal historical and ongoing studies on CAT.This review elucidates the risks,mechanisms,reliable markers,and risk assessment methodologies that can significantly guide effective interventions in clinical practice.
文摘BACKGROUND Malignant triton tumors(MTTs)comprise a subgroup of malignant peripheral nerve sheath tumors(MPNSTs)that exhibits rhabdomyosarcomatous differen-tiation and follow an aggressive course.MTTs are primarily located along peripheral nerves.Cases of MTTs in the abdominal wall have not been reported.MTT has a poorer prognosis than classic MPNSTs,and accurate diagnosis necessitates a keen understanding of the clinical history and knowledge of its differential diagnosis intricacies.Treatment for MTTs mirrors that for MPNSTs and is predominantly surgical.CASE SUMMARY A 49-year-old woman presented with a subcutaneous mass in her lower abdo-minal wall and a pre-existing surgical scar that had grown slowly over 3-4 months before the consultation.She had previously undergone radical hysterectomy and concurrent chemo-radiotherapy for cervical cancer approximately 5 years prior to the consultation.Abdominal computed tomography(CT)showed a 1.3 cm midline mass in the lower abdomen with infiltration into the rectus abdominis muscle.There was no sign of metastasis(T1N0M0).An incisional biopsy identified sporadic MTT of the lower abdomen.A comprehensive surgical excision with a 3 cm margin inclusive of the peritoneum was executed.Subse-quently,the general surgeon utilized an approach akin to the open peritoneal onlay mesh technique.The patient underwent additional treatment with an excision shaped as a mini-abdominoplasty for the skin defect.No complications arose,and annual follow-up CTs did not show signs of recurrence or metastasis.CONCLUSION An abdominal MTT was efficaciously treated with extensive excision and abdominal wall reconstruction,eliminating the need for postoperative radiotherapy.
文摘BACKGROUND The incidence of gastric cancer remains high,and it is the sixth most common cancer and the fourth leading cause of cancer deaths worldwide.Oral contrastenhanced ultrasonography is a simple,non-invasive,and painless method for the diagnosis of gastric tumors.AIM To explore the diagnostic value of oral contrast-enhanced ultrasonography for the detection of gastric tumors.METHODS The screening results based on oral contrast-enhanced ultrasonography and electronic gastroscopy were compared with those of the postoperative pathological examination.RESULTS Among 42 patients with gastric tumors enrolled in the study,the diagnostic accordance rate was 95.2%for oral contrast-enhanced ultrasonography(n=40)and 90.5%for electronic gastroscopy(n=38)compared with postoperative pathological examination.The Kappa value of consistency test with pathological findings was 0.812 for oral contrast-enhanced ultrasonography and 0.718 for electronic gastroscopy,and there was no significant difference between them(P=0.397).For the TNM staging of gastric tumors,the accuracy rate of oral contrast enhanced ultrasonography was 81.9%for the overall T staging and 50%,77.8%,100%,and 100%for T1,T2,T3,and T4 staging,respectively.The sensitivity and specificity were both 100%for stages T3 and T4.The diagnostic accuracy rate of oral contrast-enhanced ultrasonography was 93.8%,80%,100%,and 100%for stages N0,N1-N3,M0,and M1,respectively.CONCLUSION The accordance rate of qualitative diagnosis by oral contrast-enhanced ultrasonography is comparable to that of gastroscopy,and it could be used as the preferred method for the early screening of gastric tumors.

文摘BACKGROUND Function-preserving pancreatectomy can improve the long-term quality of life of patients with benign or low-grade malignant tumors,such as intraductal papillary mucinous neoplasms(IPMNs)and mucinous cystic neoplasms.However,there is limited literature on laparoscopic spleen-preserving total pancreatectomy(LSpTP)due to technical difficulties.CASE SUMMARY Patient 1 was a 51-year-old male diagnosed with IPMN based on preoperative imaging,showing solid nodules in the pancreatic head and diffuse dilation of the main pancreatic duct with atrophy of the distal pancreas.We performed L-SpTP with preservation of the splenic vessels,and the postoperative pathology report revealed IPMN with invasive carcinoma.Patient 2 was a 60-year-old male with multiple cystic lesions in the pancreatic head and body.L-SpTP was performed,and intraoperatively,the splenic vein was injured and required ligation.Postoperative pathology revealed a mucinous cystic tumor of the pancreas with low-grade dysplasia.Both patients were discharged on postoperative day 7,and there were no major complications during the perioperative period.CONCLUSION We believe that L-SpTP is a safe and feasible treatment for low-grade malignant pancreatic tumors,but more case studies are needed to evaluate its safety,efficacy,and long-term outcomes.
文摘Tuberculoma is a common condition in developing countries. In some cases, it may mimic a glial lesion, making differential diagnosis challenging. The authors report two cases of giant tuberculoma in young patients aged 14 and 16. A literature review was conducted on these cases. Both patients underwent partial excision. Histology concluded tuberculoma. Anti-tubercular treatment was implemented. The evolution one year later was marked by the persistence of neurological disorders, although they had improved.

文摘BACKGROUND Pleomorphic adenoma(PA)is the most common type of salivary gland tumor,and its common sites are parotid gland,sinus,nasal septum and cleft palate.PA is an uncommon benign type of tumor occurring in the breast,and there are few reports of cases in Asia.CASE SUMMARY An 84-year-old woman found a mass in the upper outer quadrant of the right breast>1 year ago.The patient underwent a right breast lumpectomy and sentinel lymph node biopsy.The pathological diagnosis was PA in the upper outer quadrant of the right breast,and the malignant component was malignant adenomyoepithelioma.The postoperative course was uneventful,and no chemotherapy was administered.At 18 mo of follow-up,the patient is alive and well,with no evidence of recurrent disease.CONCLUSION Patients with breast PA should first undergo extended excision of breast masses followed by pathological examination.If malignancy is confirmed or the surgical margin is positive,modified radical mastectomy should be performed.
文摘Objective To testify the efficacy of ^18F-fluorodeoxyglucose (^18F-FDG) positron emission tomography (PET) in the diagnosis of cancer. Methods A total of 170 patients with diagnosed cancer or suspicious cancer were enrolled in this study, and underwent ^18F-FDG PET. The standard uptake value (SUV) and diameter for each abnormal region in PET images were analyzed. All data were analyzed by SPSS 11.5. Results PET scan identified a primary cancer in 45.8% (11/24) patients. The sensitivity and specificity of PET scan in differentiating malignant lesions from benign ones were 78.8% (52/66) and 77.1% (27/35) respectively. Twenty-nine out of 68 (42.6%) lesions were detected earlier by PET than by computed tomography. The SHV of primary cancer was significantly higher than that of metastatic lymph nodes (5.84± 3.12 vs. 3.14± 2.24, P〈0.001). And SLIV of primary lung cancer was also significantly higher than that of metastatic lung cancer (6.30±3.01 vs. 2.86±2.37, P〈0.01).Conclusion ^18F-FDG PET plays a very important role in cancer diagnosis.

文摘Objective:The heightened prevalence of pulmonary nodules(PN)has escalated its significance as a public health concern.While the precise identification of high-risk PN carriers for malignancy remains an ongoing challenge,genetic variants hold potentials as determinants of disease susceptibility that can aid in diagnosis.Yet,current understanding of the genetic loci associated with malignant PN(MPN)risk is limited.Methods:A frequency-matched case-control study was performed,comprising 247 MPN cases and 412 benign NP(BNP)controls.We genotyped 11 established susceptibility loci for lung cancer in a Chinese cohort.Loci associated with MPN risk were utilized to compute a polygenic risk score(PRS).This PRS was subsequently incorporated into the diagnostic evaluation of MPNs,with emphasis on serum tumor biomarkers.Results:Loci rs10429489G>A,rs17038564A>G,and rs12265047A>G were identified as being associated with an increased risk of MPNs.The PRS,formulated from the cumulative risk effects of these loci,correlated with the malignant risk of PNs in a dose-dependent fashion.A high PRS was found to amplify the MPN risk by 156%in comparison to a low PRS[odds ratio(OR)=2.56,95%confidence interval(95%CI),1.40−4.67].Notably,the PRS was observed to enhance the diagnostic accuracy of serum carcinoembryonic antigen(CEA)in distinguishing MPNs from BPNs,with diagnostic values rising from 0.716 to 0.861 across low-to high-PRS categories.Further bioinformatics investigations pinpointed rs10429489G>A as an expression quantitative trait locus.Conclusions:Loci rs10429489G>A,rs17038564A>G,and rs12265047A>G contribute to MPN risk and augment the diagnostic precision for MPNs based on serum CEA concentrations.
