ABSTRACT

Objective:To investigate the diagnostic value of diffusion kurtosis imaging (DKI) quantitative parameters in lymph node metastasis of rectal cancer.Methods:The clinicopathological data of 79 patients with rectal cancers in Shanxi Province Cancer Hospital from November 2016 to March 2017 were retrospectively analyzed. All patients underwent routine magnetic resonance image (MRI) sequence and DKI sequence examinations before the operation. The tumor region of interest (ROI) was delineated by two radiologists. Matlab software was applied to calculate DKI quantitative parameters including apparent diffusion coefficient (ADC), mean diffusivity (MD) and mean kurtosis (MK) in two groups, respectively; and the consistency analysis was performed by using the interclass correlation coefficients (ICC). According to the results of postoperative pathology, all patients were divided into lymph node metastasis group and lymph node non-metastasis group; ADC, MD, MK of both groups were compared. The pathological diagnosis results were taken as the gold standard, receiver operating characteristic (ROC) curves of DKI quantitative parameters in the diagnosis of lymph node metastasis of rectal cancer were plotted, the area under the curve (AUC) was calculated, the optimal diagnostic threshold was determined based on the Yoden index, and the sensitivity and specificity were calculated.Results:The ICC of ADC, MD and MK calculated by two physicians were 0.934 (0.833-0.975), 0.963 (0.905-0.981) and 0.971 (0.949-0.991), respectively, showing a good inter-observer consistency. Among the 79 patients with rectal adenocarcinoma, 36 cases were in lymph node metastasis group and 43 cases were in lymph node non-metastasis group. MK value in lymph node metastasis group was higher than that in lymph node non-metastasis group, and the difference was statistically significant (0.97±0.08 vs. 0.89±0.09; t = -4.07, P < 0.001), while the ADC and MD values in lymph node metastasis group were lower than those in lymph node non-metastasis group, and the differences were not statistically significant (all P > 0.05). The AUC of MK value in the diagnosis of lymph node metastasis of rectal cancer was 0.735, and the corresponding sensitivity and specificity were 55.56% and 88.37%, respectively. Conclusions:DKI quantitative parameter MK has a certain diagnostic value in predicting lymph node metastasis of rectal cancer.

ABSTRACT

Objective:To investigate the value of preoperative breast MRI combined with axillary ultrasound in predicting lymphovascular invasion (LVI) of breast invasive ductal carcinoma.Methods:The clinical, pathological and imaging features of 160 female patients [age 25-74(49±10)years] with breast invasive ductal carcinoma from March 2014 to December 2017 in Shanxi Cancer Hospital were retrospectively analyzed. According to the LVI status determined by postoperative pathology, 160 patients were divided into LVI positive group (56 cases) and LVI negative group (104 cases). The clinical characteristics, pathological characteristics and imaging features of LVI positive group and LVI negative group were compared by the independent t test, Mann-Whitney U test or χ 2 test. Multivariate logistic regression analysis was performed to identify independent predictors for predicting LVI and construct a predictive model. The receiver operating characteristic (ROC) curve and area under the curve (AUC) was used to evaluate the discrimination of the prediction model, and the Hosmer-Lemeshow test was used to evaluate its calibration. Results:There was no significant difference in age, menopausal status, estrogen receptor, progesterone receptor, human epidermal growth factor 2, Ki67 index and molecular subtype between LVI positive group and negative group ( P>0.05). Tumor size, peritumoral edema, adjacent vessel sign, multifocality or multicentricity, peritumoral maximum-apparent diffusion coefficient (ADC), peritumour-tumour ADC ratio, MRI axillary lymph node status and ultrasound axillary lymph node status between LVI positive group and LVI negative group showed significantly statistical difference ( P<0.05). Variables with significant difference in the univariate analysis were entered into multivariate logistic regression analysis to explore predictors for LVI. Peritumoral edema (OR=3.367, 95%CI 1.382-8.201, P=0.008), multifocality or multicentricity (OR=4.026, 95%CI 1.268-12.776, P=0.018), high peritumoral-tumor ADC ratio (OR=7.321, 95%CI 2.226-24.079, P=0.001) and positive ultrasound axillary lymph node (OR=6.779, 95%CI 2.819-16.303, P<0.001) were independent predictors for predicting LVI. A logistic regression model was constructed using the above four indicators, and ROC showed AUC of this model for predicting LVI was 0.882, superior to any of the single indicator ( P<0.05); its sensitivity was 80.36% and specificity was 84.62%. Hosmer-lemeshow test showed that the prediction model had good calibration ( P=0.503). Conclusion:The combined prediction model constructed by preoperative breast MRI and axillary ultrasound could help to predict the LVI status of breast invasive ductal carcinoma.

ABSTRACT

Objective:To investigate the efficacy prediction and evaluation value of neoadjuvant chemotherapy for breast cancer by using dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) texture analysis.Methods:The clinical data of 63 patients with pathologically confirmed breast cancer in the Shanxi Provincial Cancer Hospital from September 2014 to October 2018 were retrospectively analyzed. All the patients underwent DCE-MRI before and after neoadjuvant chemotherapy and they were divided into the treatment-effective group (40 cases) and the treatment-ineffective group (23 cases) according to the postoperative pathological results. Texture parameters from volume transfer (Ktrans) maps of DCE-MRI before neoadjuvant chemotherapy and after 4-8 cycles of neoadjuvant chemotherapy were measured by using Omni-Kinetics software. The comparison of texture parameters between the two groups was performed by using independent sample t test or Mann-Whitney U test. The receiver operating characteristic curve was drawn and the prediction efficiency of these texture parameters in the therapeutic efficacy of neoadjuvant chemotherapy for breast cancer according to the corresponding area under the curve (AUC) was evaluated.Results:A total of 33 texture parameters were enrolled, and finally 29 texture parameters were retained. Before and after neoadjuvant chemotherapy 22 texture parameters had statistically significant difference in 63 patients (all P < 0.05). There was a statistically significant difference in 9 texture parameters between the two groups before neoadjuvant chemotherapy (all P < 0.05), including uniformity [0.17 (-0.06, 0.34), 0.39 (0.22, 0.48), Z = -2.955, P < 0.01], histogram energy [169.88 (129.36, 288.77), 116.22 (93.77, 151.95), Z = 3.241, P < 0.01] and histogram entropy [6.33 (5.71, 6.69), 6.68 (6.52, 6.97), Z = -2.991, P < 0.01]. After neoadjuvant chemotherapy, 8 of the 29 texture parameters between the two groups had statistically significant differences (all P < 0.05), including histogram entropy (6.00±0.71, 6.46±0.49, t = -2.720, P < 0.01), entropy (6.81±1.40, 8.02±1.48, t = -3.238, P < 0.01), Haralick entropy [0.49±0.10, 0.55±0.10, Z = -2.613, P < 0.01], grey level non-uniformity (GLN) [1.68 (1.42, 3.37), 4.92 (3.58, 8.50), Z = -3.897, P < 0.01], run length non-uniformity (RLN) [100.38 (65.31, 305.75), 359.75 (176.75, 655.00), Z = -4.033, P < 0.01]. There were statistical differences in 8 parameters change rate before and after neoadjuvant chemotherapy between the two groups (all P < 0.05), mainly including ΔGLN [-0.72 (-0.78, -0.60), -0.23 (-0.55, 0.36), Z = -4.554, P < 0.01], ΔRLN [-0.71 (-0.85, -0.52), -0.33 (-0.48, -0.10), Z = -4.454, P < 0.01], Δhigh grey level run emphasis (HGLRE) [1.28 (0.39, 3.46), 0.11 (-0.24, 0.86), Z = 3.184, P < 0.01]. According to the ROC curve, AUC of GLN, RLN, ΔGLN and ΔRLN after neoadjuvant chemotherapy was 0.80, 0.81, 0.85 and 0.84, respectively. Conclusion:Some texture parameters obtained from DCE-MRI Ktrans map can predict and evaluate the efficacy of neoadjuvant chemotherapy in breast cancer.

ABSTRACT

Objective@#To evaluate the predictive value of MRI features and pathological parameters on local recurrence, metastasis and progression free survival (PFS) for locally advanced rectal cancer after neoadjuvant chemoradiotherapy and subsequent total mesorectal excision surgery.@*Methods@#A retrospective analysis of 95 patients with locally advanced rectal adenocarcinoma who underwent total mesorectal excision after neoadjuvant chemoradiotherapy was performed. Univariate and multivariate analyses were performed to evaluate the predictive value of MRI features before chemoradiation and postoperative pathological parameters on progression free survival.@*Results@#Among the 95 cases, 5 cases occured local recurrence, 21 cases developed, 3 cases including both locally recurrence and distant metastasis, 19 died and 47 had no recurrence or metastasis at the last of follow-up. Univariant analysis showed that MRI signs before chemoradiation, namely, mr circumferential resection margin, mr levator ani muscle invasion, mr lymphatic vessel invasion, mr tumor deposition and postoperative pathological parameters, yp circumferential resection margin, yp lymphatic vessel invasion were related to PFS (P<0.05). Multivariate analysis of Cox proportional hazard model showed that mr lymphatic vessel invasion and mr tumor deposition were independent factors for PFS (OR=2.774 and 3.029, P<0.05).@*Conclusions@#Lymphatic vessel invasion and tumor deposition on MRI are independent prognostic factors for progression free survival of locally advanced rectal cancer after neoadjuvant chemoradiotherapy and TME surgery. To some extent, MRI signs can assess local recurrence and distant metastasis in locally advanced rectal cancer patients after neoadjuvant chemoradiotherapy and mesorectal excision.

ABSTRACT

Objective@#To investigate the magnetic resonance imaging (MRI) findings and clinicopathological features of primary lesions in patients with occult breast cancer (OBC).@*Methods@#The imaging reports from the Breast Imaging Reporting and Data System in 2013 were retrospectively analyzed to investigate the morphology and the time signal intensity curve (TIC) of breast lesions in patients with OBC. The clinical and pathological characteristics of these patients were also included.@*Results@#A total of 34 patients were enrolled. Among these patients, 24 patients underwent modified radical mastectomy and 18 of them had primary breast carcinoma in pathological sections. MRI detected 17 cases of primary lesions, including six masse lesions with a diameter of 0.6-1.2 cm (average 0.9 cm), and 11 non-mass lesions with four linear distributions, three segmental distributions, three focal distributions, and one regions distribution. Five patients had TIC typeⅠprimary lesions, ten had TIC type Ⅱ primary lesions, and two had TIC type Ⅲ primary lesions. Among all 34 cases, 23 of them had complete results of immunohistochemistry: 11 estrogen receptor (ER) positive lesions (47.8%), tenprogesterone receptor (PR) positive lesions (43.5%), seven human epidermal growth factor receptor 2 (HER-2) positive lesions (30.4%), and 20high expression(>14%) of Ki-67 (87.0%). The proportion of type luminal A was 4.3%, type luminal B was 43.5%, triple negative breast cancer (TNBC) was 30.4%, and HER-2 over expression accounted for 21.7%.@*Conclusions@#The primary lesions of OBC usually manifested as small mass lesions, or focal, linear or segmental distribution of non-mass lesions. The positive rate of ER and PR was low, but the positive rate of HER-2 and the proliferation index of Ki-67 was high. Type luminal B is the most common molecular subtype.

ABSTRACT

Objective To evaluate the value of 3.0T magnetic resonance multi-b value diffusion-weighted imaging (DWI) in evaluating the efficacy of chemotherapy for patients with central lung squamous cell carcinoma and atelectasis. Methods Twenty patients with lung squamous cell carcinoma were examined by magnetic resonance imaging (MRI) (including T1WI, T2WI and multi-b value DWI) before chemotherapy, 2 cycles of chemotherapy and 4 cycles of chemotherapy. The images, the tumor volume and changes of apparent diffusion coefficient (ADC) were analyzed. Results In the patients with central lung cancer and atelectasis, the tumor and atelectasis could be distinguished on MRI examination before radiotherapy. It was more easily identified on T2WI images after radiotherapy. In the 20 patients, the ADC values in the effective group (partial remission or complete remission) and the invalid group were increased, but the differences of ADC values in the effective group before chemotherapy, 2 cycles and 4 cycles of chemotherapy were statistically significant [b=800 s/mm2:(1.09 ± 0.52) × 10-6 mm2/s, (1.22 ± 0.59) × 10-6 mm2/s, (1.24 ± 0.52) × 10-6 mm2/s, F = 31.19, P < 0.001]. There was no significant difference in ADC values between before and after chemotherapy (b = 800 s/mm2: (1.10 ± 0.49) × 10-6 mm2/s, (1.16 ± 0.60) × 10-6 mm2/s, (1.20 ± 0.72) × 10-6 mm2/s, F=2.86, P=0.089]. When b=800 s/mm2, the ADC curve slope in the effective group was more stable, better linearity. Conclusions The MRI technique can accurately distinguish the tumor from atelectasis before and after chemotherapy. The change of ADC value after chemotherapy is earlier than that of morphological change. The change rate of b value can better evaluate the curative effect of chemotherapy.

ABSTRACT

Objective To evaluate the value of high resolution MR imaging (MRI) with diffusion weighted imaging (DWI) in the preoperative diagnosis of rectal cancer. Methods 55 patients with rectal cancer may underwent high resolution MRI examinations before surgical operation, and with DWI (b=600, 1000 s/mm2). The apparent diffusion coefficient (ADC) of the tumors were measured. The image findings were compared with pathology. Select 15 patients without rectal lesion, ADC value of the tumors and normal rectal wall were measured. Results High resolution MRI diagnosis rectal cancer sensitivity, specific degree and coincidence rate were 95.7% (45/47), 50.0% (4/8), 89.1% (49/55), high resolution MRI with DWI diagnosis colorectal cancer sensitivity, specific degree and coincidence rate were 100.0 % (47/47), 75.0 % (6/8), 96.4 % (53/55). The high resolution MRI tumor T-staging agreed with the histological stage that was 88.9% (40/45), the diagnosis of T2 stage was 87.5 % (14/16), the diagnosis of T3 stage was 89.6 % (26/29). The same b-valued under the ADC values of rectal cancer tumors and the normal rectal were different (P <0.05). No correlation can be pointed out between ADC and pathological classification of each tumor.Conclusion High resolution MRI with DWI for the rectal cancer preoperative diagnosis and T-staging has higher diagnostic accuracy, DWI can serve as an important supplement sequence of colorectal cancer diagnosis.

ABSTRACT

Objective To investigate CT feature after contrast-enhanced and anatomic distribute of the whole body lymph nodes involved by lymphoma. Methods The whole body CT findings in 89 cases (HL 12 cases, NHL 77 cases) of malignant lymphoma were retrospectively analyzed. The contrast-enhanced CT features (size, density and the digree of contrast enhancement) and anatomic distribution of the whole body lymph nodes involved by lymphoma were clarified. Results In the HL group, Diffuse and homogeneous enhancement of the enlarged lymph nodes was found in 9 cases (75.0 %), while homogeneous enhancement of the enlarged lymph nodes with some little necrosis was found in 3 cases (25.0 %). In the NHL group, diffuse and homogeneous enhancement of the enlarged lymph nodes was found in 64 cases (83.1 %), while homogeneous enhancement of the enlarged lymph nodes with some little necrosis was found in 13 cases (16.9 %). There was not statistically significant (Fisher exact probability, P = 0.4461) between the two groups. In the HL group, the enlarged lymph nodes were mixed together in 6 cases (50.0 %), while the enlarged lymph nodes were separate in 6 cases (50.0 %). In the NHL group, the enlarged lymph nodes were mixed together in 8 cases (10.4 %), while the enlarged lymph nodes were separate in 69 cases (89.6 %), there was statistically significant (Fisher exact probability, P = 0.0028). The dominant anatomic distributions of the lymph nodes involved by HL group were neck and mediastinum. The dominant anatomic distributions of the lymph nodes involved by NHL group were neck, mediastinum and abdomen, there was not statistically significant between the anatomic distributions (Fisher exact probability, P =0.110). Conclusion CT can easily demonstrate the involvement and extension of malignant involving the whole body, but CT can not differentiate HL and NHL except for the confluence state.

ABSTRACT

ObjectiveTo analyze the imageology appearance and clinical characteristics of primary squamous cell carcinoma of the breast.MethodsFeatures of MRI(4 patients)and B-type ultrasonic inspection(5 patients)of nine patients with primary squamous cell carcinoma of the breast pathologically confirmed were retrospectively reviewed. Compared with postoperative pathological appearance, the correlation between imageology appearance and clinical, pathological characteristics was analyzed. ResultsImageology appearance:In MRI:The tumor diameter was around 50 mm;The tumors were located at nearby papillae;There were two patients with pachymenia at the same time;The tumor margin was unclear,which has clear tumor wall structure and heterogeneous pachymenia,and without corpora mammillaria shadow which was toward interior;The tumors were low signal on T1WI and partially high signal on T2WI;The image with enhancement scanning showed that parenchymatous part of tumor were enhanced,while enhancements were not obviously at the centre of tumor with necrosis.In B-type ultrasonic inspection:The average diameter of tumors was around 40 mm, there were NT=0 mm in 4 cases. NT=19 mum in 1 case. The tumors presented as shape of clump or sublobe,which had unclear margin and high echoic region behind the tumor.There were also normal echo at the tumor lateral in 2 cases at the same time,and 4 cases showed blood supply was abundant, and 2 cases showed that there were colliquation and necrosis which had cystic hypoechoic signal at the tumor interior.MMG:There were class-4 in 2 cases,and Class-3 in 1 case.The tumor with little calcification which had no obvious veining showed uniformly high densities.All patients were treated with entire mastectomy. The patho-staging showed 3 cases were in ⅢB, 1 case was Ⅱ B, and 1 case was in Ⅱ A. Theresults of ER and PR with all patients were negative by using immunohistochemistry. 3 cases were also treated with chemotherapy after surgery; other organs (brain and lung) were found metabasis by follow-up visit of post-operation.ConclusionFor patients with primary squamous cell carcinoma of the breast,MMG inspection before surgery did not have specific imageology characteristics, while MRI has. The combination of MRI, B-type ultrasonic inspection and CNB can detect pathologic types and invasive circumscription,so it may have great applications for choose of surgery style and directions of therapy in the future.
