Objective To investigate differential points of clinical symptoms and pathology of solid-pseudopapillary tumor of the pancreas (SPTP) and islet cell tumor (ICT). Methods Fifteen cases of SPTP and twelve cases of ICT were studied in this retrospective research. Clinical symptom, pathologic feature and computed tomography (CT) image of patients with both tumors were analyzed, and the imaging features were compared with pathological results. Results The mean age of SPTP patients was 22.4 year-old. Twelve patients with SPTP presented a palpable abdominal mass as the initial symptom. It was observed that the tumor cells were located in a pseudopapillary pattern with a fibro-vascular core histologically. On the CT images, a mixture of solid and cystic structures could be seen in all the tumors. After taking enhanced CT scan, the solid portion was slightly enhanced in the arterial phase and the contrast intensity increased in the portal venous phase. On the other hand, the mean age of ICT patients was 39.3 year-old. The major symptom was due to the function of islet cell tumor, which was typical in 8 patients, presenting as Whipple triad. Histologically, cells demonstrated in trabecular, massive, acinar or solid patterns, and the blood supply of the tumor was abundant. On the CT images, most small tumors were difficulty to be detected. ICT could be markedly enhanced in the arterial phase and slightly enhanced in the portal venous phase on post-contrast CT scan. Conclusion Clinical symptom, pathologic feature and CT scanning are helpful to differentiate SPTP from ICT.
ObjectiveTo explore the correlation of clinicopathologic factors with the expression of estrogen receptor (ER) and progesterone receptor (PR) in patients with primary breast cancer. MethodsThe data of 105 patients with primary breast cancer were collected from September 2011 to September 2012. The expression of ER, PR and C-erbB-2 in breast cancer tissues was detected by immunohistochemistry. The correlation between the expression of ER, PR and C-erbB-2 and the clinicopathologic factors was evaluated. ResultsThe positive rates of expression of ER, PR and C-erbB-2 in breast cancer tissues reached 58.1%, 49.5% and 59.0%, respectively. The expression of ER had a positive correlation with the expression of PR. The concordance expression of ER and PR had a negative correlation with the expression of C-erbB-2. The positive rate of expression of ER had a correlation with the lymph node metastasis and histological grading, while it was not correlated with patients' age, the age of menarche, tumor size, tumor position, clinical stages, pathological type, or pathologic morphology of tissue adjacent to cancer (P>0.05). The positive rate of expression of PR and the different positive strength rate of expression of ER were not correlated with clinical and pathological factors (P>0.05). The positive rate of expression of C-erbB-2 in the group with lymph node metastasis was higher than that in non-lymph node metastasis group (P<0.05). ConclusionThe expression of ER and PR plays an important role in the occurrence and development of the breast cancer. Joint detection of ER and PR is very important for the evaluation of endocrine therapy effect and prognosis.
ObjectiveTo investigate the rule of lymph node metastasis in early gastric cancer (EGC) so as to provide a reasonable treatment. MethodsWe retrospectively analyzed the clinical data of 118 EGC patients who had been treated from January 2006 to December 2012,and a total of 8 potential factors associated with occurrence of EGC were evaluated by univariate analysis and multivariate logistic regression analysis. ResultsThe univariate analysis showed that ulcer,tumor size,depth of invasion and lymphatic involvement were correlated with lymph node metastasis (P<0.05).Multivariate logistic regression analysis showed that presence of an ulcer (OR=2.872),tumor of 3.0 cm or larger than that (OR=2.351),tumor invasion into the submucous layer (OR=3.461) and invasion into the lymphatic tubes (OR=1.784) were found to be independent risk factors. ConclusionLymph node metastasis of EGC is correlated with many factors,so EGC treatment choice should be made reasonably based on strict screening to exclude various risk factors before taking surgery.
