A Comparative Study of Ultrasound-Guided Microwave Ablation, Surgery and Rotational Adenomammectomy for Benign Breast Nodules

Objective: To explore the clinical effects of conventional surgery, ultrasound-guided microwave ablation and rotational adenomammectomy on the prognosis of benign breast nodules. Methods: 232 cases of patients with benign breast nodules confirmed by pathological examination who received surgical treatment in the breast surgery department of our hospital from December 2016 to December 2020 were included. According to the surgical methods, they were divided into microwave ablation group (n = 48), conventional surgery group (n = 105) and rotational adenomammectomy group (n = 79). The clinical parameters were compared and analyzed between the three groups, and the postoperative pain, residual tumor, breast beauty and complication rate of the patients were evaluated. Results: Operative time, intraoperative blood loss, healing time and postoperative pain in microwave ablation group were lower than those of rotational adenomammectomy group (P < 0.05) and those of conventional surgery group (P < 0.05). Besides, those in the rotational adenomammectomy group were lower than those in the conventional surgery group (P < 0.05). The residual tumor rates in microwave ablation group and rotational adenomammectomy group were 4.17% and 3.80%, respectively. And the difference was not statistically significant (P > 0.05). Both of them were lower than 6.66% in conventional surgery group, with statistically significant differences (P < 0.05). The effective rates of breast beauty were 91.67%, 82.28% and 68.58% in the microwave ablation group, the rotational adenomammectomy group and the conventional surgery group, respectively. And the difference between groups was statistically significant (P < 0.05). The rate of postoperative complications in microwave ablation group and rotational adenomammectomy group were 4.17% and 3.80% respectively, both of which were significantly lower than 6.66% in conventional surgery group (P < 0.05). Conclusion: Microwave ablation, rotational adenomammectomy and conventional surgery are effective for the treatment of benign breast tumors. Among them, microwave ablation is the best option with many advantages of shorter operative time, less intraoperative blood loss, more beautiful breast shape, less postoperative pain, a lower residual rate after surgery, and a lower complication rate.

Tongue image feature correlation analysis in benign lung nodules and lung cancer

Objective To analyze the differences in the correlation of tongue image indicators among patients with benign lung nodules and lung cancer.Methods From July 1;2020 to March 31;2022;clinical information of lung cancer patients and benign lung nodules patients was collected at the Oncology Department of Longhua Hos-pital Affiliated to Shanghai University of Traditional Chinese Medicine and the Physical Ex-amination Center of Shuguang Hospital Affiliated to Shanghai University of Traditional Chi-nese Medicine;respectively.We obtained tongue images from patients with benign lung nod-ules and lung cancer using the TFDA-1 digital tongue diagnosis instrument;and analyzed these images with the TDAS V2.0 software.The extracted indicators included color space pa-rameters in the Lab system for both the tongue body(TB)and tongue coating(TC)(TB/TC-L;TB/TC-a;and TB/TC-b);textural parameters[TB/TC-contrast(CON);TB/TC-angular second moment(ASM);TB/TC-entropy(ENT);and TB/TC-MEAN];as well as TC parameters(perAll and perPart).The bivariate correlation of TB and TC features was analyzed using Pearson’s or Spearman’s correlation analysis;and the overall correlation was analyzed using canonical correlation analysis(CCA).Results Samples from 307 patients with benign lung nodules and 276 lung cancer patients were included after excluding outliers and extreme values.Simple correlation analysis indi-cated that the correlation of TB-L with TC-L;TB-b with TC-b;and TB-b with perAll in lung cancer group was higher than that in benign nodules group.Moreover;the correlation of TB-a with TC-a;TB-a with perAll;and the texture parameters of the TB(TB-CON;TB-ASM;TB-ENT;and TB-MEAN)with the texture parameters of the TC(TC-CON;TC-ASM;TC-ENT;and TC-MEAN)in benign nodules group was higher than lung cancer group.CCA further demon-strated a strong correlation between the TB and TC parameters in lung cancer group;with the first and second pairs of typical variables in benign nodules and lung cancer groups indicat-ing correlation coefficients of 0.918 and 0.817(P<0.05);and 0.940 and 0.822(P<0.05);re-spectively.Conclusion Benign lung nodules and lung cancer patients exhibited differences in correla-tion in the L;a;and b values of the TB and TC;as well as the perAll value of the TC;and the texture parameters(TB/TC-CON;TB/TC-ASM;TB/TC-ENT;and TB/TC-MEAN)between the TB and TC.Additionally;there were differences in the overall correlation of the TB and TC be-tween the two groups.Objective tongue diagnosis indicators can effectively assist in the diag-nosis of benign lung nodules and lung cancer;thereby providing a scientific basis for the ear-ly detection;diagnosis;and treatment of lung cancer.

Percutaneous Removal of Benign Breast Lesions with an Ultrasound-guided Vacuum-assisted System:Influence Factors in the Hematoma Formation

Objective To explore the influence factors in hematoma formation after removing benign breast lesions with an ultrasound-guided vacuum-assisted system.Methods A total of 232 females with 312 benign breast masses received excisional biopsy with ultrasoundguided vacuum-assisted system.The pathology of patients,results of hematoma development and outcome,influence factors for hematoma occurrence(nodule size,nodule location,number of nodule,breast shape,menstrual period,efficacy time of bandage,and application of hemostatic agents during the procedure) were recorded.Results Pathologic examination revealed fibroadenomas in 138 lesions,fibroadenosis in 127 lesions,intraductal papillomas in 39 lesions,inflammatory change in 4 lesions,retention cyst of the breast in 3 lesions,and benign phyllodes tumor in 1 lesion.Thirty hematomas were observed in patients(9.6%).Finally,97.0%hematomas were absorbed completely within 6 months follow-up.The incidence rates of hematoma were increased by 24.7%,10.0%,63.2%,13.9%in the nodule diameter larger or equal to 25 mm group,removal of larger or equal to two nodules once time from one patient group,menstrual period group,and larger and loose breast group,respectively(all P<0.05).However,the incidences were decreased by 60.6%in the bandage performed for 12-24 hours or beyond 24 hours group(P<0.05).The multiple logistic regression models revealed that nodule size(x^2=15.227,P<0.001),number of nodule(x^2=7.767,P=0.005),menstrual period(x^2=24.530,P<0.001),and breast shape(x^2=9.559,P=0.002) were independent risk factors associated with hematoma occurrence,but efficacy time of bandage was a protective factor associated with hematoma occurrence.Conclusion The occurrence of hematoma after the minimally invasive operation was associated with nodule size,number of nodule,menstrual period,breast shape,and efficacy time of bandage.

Expression and Clinical Significance of Vascular Endothelial Growth Factor in Benign and Malignant Tissues of Breast

Objective： To detect the expression of vascular endothelial growth factor （VEGF） and microvessel density （MVD） count in breast benign affection, breast atypical hyperplasia and breast carcinoma in situ, and to clarify the relationship between VEGF expression, MVD and the clinicopathological features of these diseases. Methods： The expression of VEGF and MVD count in 115 cases breast benign diseases （including 40 breast fibroid tumor, 40 breast cystic hyperplasia and 35 intraductal papilloma, 19 breast atypical hyperplasias and 32 breast carcinomas in situ were examined by immunohistochemistry staining （SP-method）. Results： The positive rate of VEGF in breast benign diseases, breast atypical hyperplasia and breast carcinoma in situ were 21.74%（25/115）, 31.58.% （6/19）and 53.13%（17/32） respectively. It was the lowest in breast benign affection group, and was the highest breast carcinoma in situ group. The expression of VEGF increased gradually in the three groups （P〈0.05）. The MVD count of the three groups were 14.41 ± 2.59, 18.89± 4.47 and 21.13 ± 4.12 respectively, It was the lowest in breast benign affection group, and was the highest breast carcinoma in situ group. The MVD count of the three groups increased gradually （P〈0.05）. In VEGF positive group, MVD count was 19.41 ±4.78; In VEGF negative group, MVD count was 14.91±3.15. The MVD count was higher in VEGF positive group than that in VEGF negative group （P〈0.05）. Conclusion： The results of this study suggested that VEGF could promote microvessel growth in breast tumors. The occurrence and progression of breast cancer might be related with the expression of VEGF.

Perithyroidal hemorrhage caused by hydrodissection during radiofrequency ablation for benign thyroid nodules:Two case reports

BACKGROUND Hydrodissection is a widely used technique during radiofrequency ablation(RFA)for benign thyroid nodules.Although it could effectively avoid thermal injury to the surrounding critical structures and achieve complete treatment,routine operation of the remaining needle could cause perithyroidal hemorrhage.In this report,we present 2 cases of perithyroidal hemorrhage during RFA caused by a hydrodissection needle,which have not been reported before.CASE SUMMARY A 21-year-old female and a 45-year-old male were admitted for RFA for benign thyroid nodules.Considering that their nodules were adjacent to the recurrent laryngeal nerve,the needle used for hydrodissection was placed and remained between the dorsal capsule of the lateral lobe and the recurrent laryngeal nerve.During the procedure,active bleeding near the needle appeared on ultrasonography(US).Although moderate pressure was quickly applied to the neck for several minutes,contrast-enhanced US(CEUS)still showed an active hemorrhage.A radiofrequency electrode was placed at the bleeding point under the guidance of CEUS to stop the bleeding,and the procedure was finally confirmed to be successful by CEUS,without other complications.CONCLUSION Hydrodissection during RFA of benign thyroid nodules was associated with a risk of perithyroidal hemorrhage.The timely recognition of this acute hemorrhage could help in the timely control of the bleeding,and CEUS-guided ablation of the bleeding point could be useful.

Male Breast Nodules in Ouagadougou (Burkina Faso): Radiological and Histopathological Aspects

Objective: To describe the radiological and histological aspects of breast nodules among men in our practice setting. Methodology: This is a descriptive and retrospective study conducted from January 2014 to October 2017. The study included male patients with breast nodules classified ACR3, 4 or 5 after a mammographic and ultrasound scan. These lesions were explored through an ultrasound-guided breast microbiopsy. The following are the variables collected: age, family history of breast cancer, medical history, ACR classification, nodule size, and anatomopathologic diagnosis. Results: 13 breast nodules were explored among 13 male subjects. Mammography and breast ultrasound enabled to identify one ACR3 lesion, 10 ACR4 lesions and 2 ACR5 lesions. The average age was 56.53 ± 14.63 years and the average size of the nodules 28.91 ± 13.62 mm. As for histology, there were seven malignant tumors and six benign tumors. The average age of patients with malignancy was 61.45 ± 13.62 years. The malignant nodules average size was 29.45 ± 12.54 mm. Malignant tumors exclusively consisted of invasive breast carcinomas while Benign ones consisted of dystrophic and inflammatory lesions. Conclusion: Most often Breast lesions among men had an indeterminate appearance on imaging and were predominantly malignant in histopathology.

HPV positivity varies with technique and primer set, in formalin-fixed paraffin-embedded benign and malignant breast tissue from Malta

The role of human papillomavirus in breast cancer pathogenesis is an area of considerable debate following differing results from all over the world. This study analyzed paraffin embedded tissue from 19 patients with benign or malignant breast disease. Standard PCR with GP5+/6+ and FAP primers, proved negative in all cases. However, qRT-PCR using the SF10 primer set detected HPV DNA in 2 out of these samples. Whilst our data does not support a major role for HPV in the pathogenesis of breast disease in Malta, it definitely does not exclude it totally. This study also clearly shows that the method of analysis is one of the variables resulting in the range of differing results witnessed worldwide in this area of study.

Difference in microvascular structure between benign and malignant pulmonary nodules and its relationship with CT enhancement

Objective： To investigate the enhancement basis and the mechanisms of solitary pulmonary nodules （SPNs） by comparing the differences in microvascular structure between benign and malignant lesions. Methods： Dynamic contrast-enhanced CT scan was performed on 53 patients with SPNs （diameter〈3 cm, 38 peripheral lung cancers, 5 hamartomas, 10 inflammatory lesions） using a Siemens Plus S or a Marconi MX8000 multi slices spiral CT scanner. The time-attenuation curves were interpreted. The microvascular density （MVD） and the continuity of the microvessels＇ basemental membrane in the dissected specimens were observed with the ABC （avldin-biotin complex） immuno-histochemical method in all patients. Results ：The CT enhancement values of lung cancer （49.05± 16.08 HU） and inflammatory lesions （49.59±21.30 HU） were significantly higher than those of hamartoma （8.98±4.56 HU） t=7.48, P〈0.051 t=8.35, P〈0.05）. But the enhancement of lung cancer was similar to that of inflammatory lesions （t=0.76, P±0. 05）. The time attenuation curve of inflammatory lesions tended to increase faster and reached a higher peak compared to the lung cancer, and both of them maintained a high plateau after crossing. The hamartoma showed a slight increase in the time-attenuation curve and demonstrated a lowplateau curve. The MVD of SPNs was positively correlated with CT enhancement （r=0. 8051）. The microvascular counts of peripheral lung cancer （48.45±10. 09） and inflammatory lesions （49. 60±19. 94） were significantly higher than those of hamartoma （8.70±7. 30） （t=11. 64, P〈0.001, t=6. 09, P〈0. 001 ）, but no significant difference was found between lung cancer and inflammatory lesions （t= -0.26, P=0.799）. There was no difference in the continuity of basement membrane between nodules with anen haneement less than 30 HU and those with an enhancement higher than 30HU （X^2=3. 13, P〉0.05 ）. Conclusion： The microvascular counts mainly contribute to the enhancement value of SPNs. The basement membrane is not related to nodule enhancement, but it might influence the pattern of the time-attenuation curve.

Clinical study of preoperative fT4/fT3 quotient and thyroid function test in distinguishing benign from malignant thyroid nodules

Objective:To analyze the clinical and pathological characteristics of thyroid nodules and to explore the related risk factors of malignant thyroid nodules.Methods: According to the criteria of inclusion and exclusion, a total of 283 patients with thyroid nodules during January 2015 and December 2017 were divided into benign group (benign nodule,n =172) and malignant group (malignant nodule,n = 111) based on postoperative histopathological results. The age, sex, serum thyroglobulin antibody (TgAb), thyroid peroxidase antibody (TPOAb), thyroid stimulating hormone (TSH), free thyroxine (fT4), free three iodine thyroxine (fT3) and fT4/ fT3 ratio were subjected to univariate analysis, and the risk factors of malignant thyroid nodule were screened by multivariate logistic regression analysis.Results:Univariate analysis showed that age, TgAb, fT4 (P < 0.05) and fT4/ fT3 quotient (P < 0.01) were significantly different between the two groups. The fT4/fT3 quotient is a risk factor of malignant nodules. Multivariate logistic regression analysis indicated that the risk factors of malignant thyroid nodule were age (0R: 0.934,95% CI:0.911-0.957), TgAb(0R: 2.069,95% CI: 1.008-4.247) and fT4 (0R: 1.206,95% CI: 1.038-1.401).Conclusion: The fT4/fT3 quotient has important diagnostic value in differentiating benign and malignant thyroid nodules. When fT4 / fT3 > 3, it increases the risk of malignancy. The age, TgAb and fT4 are independent risk factors for malignant thyroid nodule, which is of great value in distinguishing benign from malignant thyroid nodules.

Evaluation of Diagnostic Value of Ultrasound and Magnetic Resonance Imaging for Malignant and Benign Breast Lesions

Objectives:To investigate diagnostic value of ultrasound and magnetic resonance imaging(MRI)for malignant and benign breast lesions.Methods:Retrospective analysis of treatment data of 48 patients diagnosed with malignant and benign breast lesions in our hospital,collected from December 2017 to November 2018.A total number of 56 breast masses were examined by both ultrasound and MRI,and were compared with postoperative pathological biopsy results.Results:Postoperative pathological biopsy results showed that there were 26 and 30 malignant and benign lesions respectively.Comparison of MRI curve type of malignant and benign lesions showed statistical significance(P<0.05).By comparison with pathological biopsy results,specificity and sensitivity of ultrasound diagnosis were 83.33%(25/30)and 84.61%(22/26)respectively;specificity and sensitivity of MRI diagnosis were 96.66%(29/30)and 92.30%(24/26)respectively.Conclusions:Ultrasonographic examination of malignant and benign breast lesions is straight-forward,simple and inexpensive.Accuracy,specificity and sensitivity of MRI are significantly higher than ultrasound in examining malignant and benign breast lesions,this can reduce misdiagnosis.

Radio-Histopathological Aspects of Breast Nodules in a Sub-Saharan African City (Ouagadougou, Burkina Faso)

Objective: To determine the diagnostic contribution of breast microbiopsy percutaneously under ultrasound guidance. Methodology: Retrospective descriptive study conducted from January 2014 to October 2017. The included patients had an ultrasound-guided breast microbiopsy after a mammographic and ultrasound scan. The variables collected were gender, age, nodule size, ACR classification and anatomopathologic diagnosis. Results: 347 nodules were explored in 313 patients. There were 300 women (95.85%) and 13 men (4.15%), a gender ratio of 23.07. The average age was 44.64 ± 14.18 years. The average size of the nodules was 30.33 ± 19.58 mm. There were 53.89% ACR4 grade nodules, 48% ACR5 nodules and 32.28% ACR3 nodules. 86.49% of ACR3 nodules were benign and 97.92% of ACR5 nodules were actually malignant. Malignant tumors accounted for 50.29% of the nodules and were dominated by invasive breast carcinomas in 98.26%. The average age of patients with malignant tumors was 49.15 ± 11.55 years. 16% of patients with malignancy were aged under 40 years old. Conclusion: The diagnostic yield was satisfactory and there was a good correlation between the rate of malignant and benign lesions and the positive predictive values of malignancy in the literature.

Pulmonary benign metastasizing leiomyoma: A case report and review of the literature

BACKGROUND Pulmonary benign metastatic leiomyoma(PBML),which is very rare,is a type of benign metastatic leiomyoma(BML).Here,we report a case of PBML,finally diagnosed through multidisciplinary team(MDT)discussions,and provide a literature review of the disease.CASE SUMMARY A 55-year old asymptomatic woman was found to have bilateral multiple lung nodules on a chest high-resolution computed tomography(HRCT)scan.Her medical history included total hysterectomy for uterine leiomyoma.The patient was diagnosed with PBML,on the basis of her clinical history,imaging manifestations,and computed tomography(CT)-guided percutaneous lung puncture biopsy,via MDT discussions.As the patient was asymptomatic,she received long-term monitoring without treatment.A follow-up of chest HRCT after 6 mo showed that the PBML lung nodules were stable and there was no progression.CONCLUSION For patients with a medical history of hysterectomy and uterine leiomyoma with lung nodules on chest CT,PBML should be considered during diagnosis based on the clinical history,imaging manifestations,CT-guided percutaneous lung puncture biopsy,and MDT discussions.

Differentiation of Benign and Malignant Solitary Pulmonary Nodule: Literature Review

The solitary pulmonary nodule (SPN) is frequently seen on chest radiographs and computed tomography (CT), usually the identification is accidental. The overall prevalence of malignancy is relatively low but identification of malignancy of nodule is of prime importance. There are different characters of nodules indicating malignancy, and also the exposure of person to risk factors increases the chances of malignancy of nodule. Chances of malignancy rise with increasing size, the irregular, lobulated border of the nodules is highly associated with higher probability of malignancy and nodules with pure ground grass appearance have higher probability of malignancy, irregularly marginated nodule displaying a corona radiata sign indicating neoplastic infiltration with distortion of neighbouring tissue is almost certainly a malignant nodule. Stippled, punctuate, and eccentric calcifications are suggestive of malignancy. There are 20% - 75% of chances of malignancy if nodule is appeared with ground-glass opacity. Malignant nodules have higher growth rate as compared with benign nodules, malignant nodules usually have doubling time (DT) of 30 - 400 days while DT of more than 450 days is sign of benignity whereas doubling time less than 30 days is usually acute infectious process. The presence of fat within nodule is sign of benignity. Increasing density of the nodule is suggestive of malignancy and requires shorter follow up. Besides the nodule evaluation the chances of malignancy can also be evaluated through the exposure of patient to risk factors like age, current and past smoking status and history of extra thoracic malignancy. The management depends upon various factors mainly three strategies are applied for management including careful observation of nodule, use of diagnostic techniques like CT FNA, PET, and broncoscopy and surgery.

Complications Following Radiofrequency Ablation of Benign Thyroid Nodules： A Systematic Review

Objective： This systematic review examined whether radiofrequency ablation （RFA） is a sate treatment modality for benign thyroid nodules （BTNs）. Data Sources： PubMed, Embase, and the Cochrane Library database were searched for articles that （a） targeted human beings and （b） had a study population with BTNs that were confirmed by fine-needle aspiration cytology and/or core needle biopsy. Study Selection： Thirty-two studies relating to 3409 patients were included in this systematic review. Results： Based on literatures, no deaths were associated with the procedure, serious complications were rare, and RFA appears to be a sale and well-tolerated treatment modality. However, a broad spectrum of complications offers insights into some undesirable complications, such as track needle seeding and Hornet syndrome. Conclusions： RFA appears to be a safe and well-tolerated treatment modality for BTNs. More research is needed to characterize the complications of RFA for thyroid nodules.

Comparative FTIR spectroscopic analysis of human breast benign and malignant tissues

Some remarkable FTIR spectral differences are observed and the differences at the molecular level are extracted between benign and malignant breast tissue samples. For the malignant tissue, the relative content of nucleic acids is increased whereas the collagen is decreased. The proteins are phosphorylated and become more flexible and disordered. And these significant differences have important implications not only for probing the process of the breast lesion at the molecular level, but also for evaluating the histological types and grades of breast diseases.

FTIR assessment of the secondary structure of proteins in human breast benign and malignant tissues

The compositions of the secondary structures of protein in the human breast normal, hyperplasia, fibroadenoma and invasive ductal carcinoma tissues have been estimated from the Fourier self deconvolved spectra, the second derivative spectra and the curve-fitting analysis of the amide I bands in their spectra. Some parameters of the secondary structures of proteins in these 4 types of tissues are significantly different and located in separate ranges.
