BACKGROUND The incidence rate of breast cancer has exceeded that of lung cancer,and it has become the most malignant type of cancer in the world.BI-RADS 4 breast nodules have a wide range of malignant risks and are associated with challenging clinical decision-making.AIM To explore the diagnostic value of artificial intelligence(AI)automatic detection systems for BI-RADS 4 breast nodules and to assess whether conventional ultrasound BI-RADS classification with AI automatic detection systems can reduce the probability of BI-RADS 4 biopsy.METHODS A total of 107 BI-RADS breast nodules confirmed by pathology were selected between June 2019 and July 2020 at Hwa Mei Hospital,University of Chinese Academy of Sciences.These nodules were classified by ultrasound doctors and the AI-SONIC breast system.The diagnostic values of conventional ultrasound,the AI automatic detection system,conventional ultrasound combined with the AI automatic detection system and adjusted BI-RADS classification diagnosis were statistically analyzed.RESULTS Among the 107 breast nodules,61 were benign(57.01%),and 46 were malignant(42.99%).The pathology results were considered the gold standard;furthermore,the sensitivity,specificity,accuracy,Youden index,and positive and negative predictive values were 84.78%,67.21%,74.77%,0.5199,66.10%and 85.42%for conventional ultrasound BI-RADS classification diagnosis,86.96%,75.41%,80.37%,0.6237,72.73%,and 88.46%for automatic AI detection,80.43%,90.16%,85.98%,0.7059,86.05%,and 85.94%for conventional ultrasound BI-RADS classification with automatic AI detection and 93.48%,67.21%,78.50%,0.6069,68.25%,and 93.18%for adjusted BI-RADS classification,respectively.The biopsy rate,cancer detection rate and malignancy risk were 100%,42.99%and 0%and 67.29%,61.11%,and 1.87%before and after BI-RADS adjustment,respectively.CONCLUSION Automatic AI detection has high accuracy in determining benign and malignant BI-RADS 4 breast nodules.Conventional ultrasound BI-RADS classification combined with AI automatic detection can reduce the biopsy rate of BI-RADS 4 breast nodules.

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.

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.

A study on the frequency of thyroid nodules and uterine fibroids in Chinese breast cancer patients

Background:Single or multiple thyroid nodules and uterine fibroids are the most common benign gynecologic disease.An increasing number of breast cancer are accompanied with thyroid nodules or uterine fibroids or both of them.However,the incidence of thyroid nodules or uterine fibroids in patients with different subtypes of breast cancer is unclear.Objective:To study the incidence of thyroid nodules or uterine fibroids in patients with different subtypes of breast cancer.Methods:A retrospective cohort study conducted in the First Teaching Hospital of Tianjin University of Traditional Chinese Medicine(China)that included 1,322 female cancer survivors who went to our hospital from January 2014 to November 2019.In this study,we evaluated the frequency of thyroid nodules and uterine fibroids in breast cancer survivors in comparison with other cancer survivors.Besides,we compare the frequency of thyroid nodules and uterine fibroids among different luminal breast cancer.Results:In this study,there were 245 breast cancer survivors,including 58 cases with thyroid nodule,52 cases with uterine fibroids,17 cases with both,152 cases with none.And 1,077 other cancer survivors were collected,including 142 cases with thyroid nodule,172 cases with uterine fibroids,25 cases with both,788 cases with none.According to statistical analysis,the incidence of thyroid nodule and uterine fibroids in breast cancer patients is significantly higher than that in non-breast cancer patients(P<0.01 and P<0.05).Between the molecular classification of breast cancer,among 245 BC patients,58 were combined with thyroid nodule,including 57 cases of luminal-A type BC and 22 cases of combined thyroid nodule;101 cases of luminal-B type BC and 20 cases of combined thyroid nodule;50 cases of HER2-positive over expression type BC and 13 cases of combined thyroid nodule;37 cases of TNBC and 3 cases of combined thyroid nodule,Patients with luminal-A BC have a higher incidence of thyroid nodules compared to other types of BC.Among 245 BC patients,there were 52 cases with uterine fibroids,including 57 cases of luminal-A type BC,5 cases with uterine fibroids;101 cases of luminal-B type BC,32 cases with uterine fibroids;50 cases of HER2-positive over expression type BC,11 cases with uterine fibroids;37 cases of TNBC,4 cases with uterine fibroids.Luminal-B breast cancer is more likely to suffer from uterine fibroids than other types of breast cancer.In addition,breast cancer patients with both thyroid nodules and uterine fibroids had significantly higher luminal-B than other subtypes.Conclusions:This study demonstrates that breast cancer women have a significantly greater incidence rate of thyroid nodules and uterine fibroids,and is higher at Luminal A or Luminal B.We consider these findings may contribute to the identification of liver channel of foot jueyin following underlying this disease association.

Characteristics of multiple nodules in a patient with pulmonary Langerhans cell histiocytosis: A case report

BACKGROUND The common computed tomography findings of pulmonary Langerhans cell histiocytosis (PLCH) are multiple cysts and micronodules predominantly in middle to upper lung lobes.Non-cystic nodules and large nodules are atypical findings of PLCH.CASE SUMMARY The patient was a 48-year-old Japanese man with a smoking history (20 cigarettes/d,28 years) and no symptoms.Multiple nodules existed in all lung lobes,predominantly in the right lower lobe.Some nodules seemed to be distributed randomly,and others were adjacent to bronchus.Most nodules were solid;some small ones were cystic.The largest nodule was 22 mm in diameter.Although metastatic lung tumors were suspected,thoracoscopic lung biopsy led to the diagnosis of PLCH.At 6 months after he quit smoking,all nodules had almost disappeared.We investigated the characteristics of nodules at diagnosis in detail.Of 349 nodules in total,116 were in upper and 199 were in lower lobes.Ninety-six (27.5%) were cystic;the remaining 253 (72.5%) were non-cystic.The prevalence of cystic nodules was higher in upper lobes than in lower lobes (right upper 37.5% vs lower 18.2%,P = 0.0068;left upper 48.1% vs lower 24.4%,P = 0.0078).The average size (dia.) of cystic nodules was smaller than that of noncystic nodules (5.03 mm vs 7.40 mm,respectively,P < 0.0001).CONCLUSION Although multiple non-cystic nodules including large nodules (over 20 mm) are atypical,PLCH should be included in differential diagnoses.The presence of small cystic nodules predominantly in upper lobes and asymptomatic situation are also important for differential diagnoses to distinguish from metastatic cancers.

Long-term survival of the Sister Mary Joseph nodule originating from breast cancer:A case report

BACKGROUND A Sister Mary Joseph nodule(SMJN)is an uncommon cutaneous metastasis found in the umbilicus,indicating an advanced malignancy.SMJNs typically originate from intra-abdominal sources,rarely from breast cancer.Diagnosis suggests a poor prognosis with a median survival of approximately 8 mo after detection.Managing patients with SMJNs is challenging,as most receive limited palliative care only.The optimal strategy for long-term survival of these patients remains unclear.CASE SUMMARY A 58-year-old female,previously diagnosed with right breast cancer 17 years ago and underwent breast-conserving surgery,adjuvant radiotherapy,and endocrine therapy,presented with a 2-cm umbilical nodule.Thirteen years previously,metastases were detected in the right supraclavicular,infraclavicular,hilar,and mediastinal lymph nodes.An umbilical nodule emerged four years before the date of presentation,confirmed as a skin metastasis of primary breast cancer upon excisional biopsy.Despite initial removal,the nodule recurred and grew,leading to her referral to our hospital.The patient underwent extensive excision of the umbilical tumor and immediate abdominal wall reconstruction.Endocrine therapy was continued postoperatively.Five years later,no local recurrence was observed,and the patient continued to work full-time,achieving over 9 years of survival following SMJN diagnosis.CONCLUSION This case study aimed to identify the optimal strategy for achieving extended survival outcomes in patients with SMJN through comprehensive treatment.We presented a case of the longest survival in a patient after undergoing a multidisciplinary treatment regimen.Our findings underscore the significance of adopting a multimodal treatment approach comprising timely and wide excision along with adjunctive therapy.This approach can control the disease,prolong survival,and improve the quality of life in patients with SMJN.

Simultaneous Paragonimus infection involving the breast and lung:A case report

BACKGROUND Paragonimiasis is a food-borne parasitic infection caused by lung flukes of the genus Paragonimus. Although the most common site of infection is the pleuropulmonary area, the parasite can also reach other parts of the body on its journey from the intestines to the lungs, ending up in locations such as the brain,abdomen, skin, and subcutaneous tissues. Ectopic paragonimiasis is difficult to diagnose due to the rarity of this disease.CASE SUMMARY Here, we report a rare case of simultaneous breast and pulmonary paragonimiasis in a woman presenting painless breast mass and lung nodule with a history of eating raw trout. To confirm the diagnosis, serologic testing and tissue confirmation of the breast mass were performed. The patient was treated with surgical resection of the mass and praziquantel medication.CONCLUSION Ectopic paragonimiasis is difficult to diagnose due to the rarity of this disease.Thus, thorough history-taking and clinical suspicion of parasitic infection are important.

Endoscopic Thyroid Lobectomy via Axillary-Breast-Shoulder Approach versus Open Thyroid Lobectomy

Introduction: The aim of the study was to compare the feasibility and safety of endoscopic thyroid lobectomy via axillary-breast-shoulder approach (ET via ABS) with a conventional open thyroid lobectomy (OT). Methods: From November 2014 to December 2015, 20 patients with unilateral benign thyroid nodules were treated with ET via ABS and another 20 patients were treated with an OT. We analyzed the clinical characteristics postoperative complications, pain, and patient satisfaction. Results: No statistically significant differences occurred between groups except the mean ages of the OT group and the ET via ABS group were 55 and 44 years, respectively (p = 0.015). The mean operative time was almost the same in both groups (116 min in the OT group and 114 min in the ET via ABS group). Blood loss was significantly higher in the OT group than in the ET via ABS group (p = 0.042) but postoperative drainage was detected more in the ET via ABS group (p p = 0.026). The hospital stay was three days in OT group and four days in ET via ABS group (p = 0.909). Postoperative complications such as hematoma, hoarseness, dysphagia, and prolonged subcutaneous emphysema were detected only in the ET via ABS group but without statistical difference. More patients were “very satisfied” with the treatment in the ET via ABS group than in the OT group. Conclusion: The ET via ABS is as safe and effective as the OT for patients with unilateral thyroid nodules. With less early postoperative pain and higher patient satisfaction, this endoscopic thyroidectomy approach should be considered in patients who concern about cosmetic results.

Prospective Study of Low-and Standard-dose Chest CT for Pulmonary Nodule Detection:A Comparison of Image Quality,Size Measurements and Radiation Exposure

Objective:To comprehensively and accurately analyze the out-performance of low-dose chest CT(LDCT)vs.standard-dose CT(SDCT).Methods:The image quality,size measurements and radiation exposure for LDCT and SDCT protocols were evaluated.A total of 117 patients with extra-thoracic malignancies were prospectively enrolled for non-enhanced CT scanning using LDCT and SDCT protocols.Three experienced radiologists evaluated subjective image quality independently using a 5-point score system.Nodule detection efficiency was compared between LDCT and SDCT based on nodule characteristics(size and volume).Radiation metrics and organ doses were analyzed using Radimetrics.Results:The images acquired with the LDCT protocol yielded comparable quality to those acquired with the SDCT protocol.The sensitivity of LDCT for the detection of pulmonary nodules(n=650)was lower than that of SDCT(n=660).There was no significant difference in the diameter and volume of pulmonary nodules between LDCT and SDCT(for BMI<22 kg/m^(2),4.37 vs.4.46 mm,and 43.66 vs.46.36 mm^(3);for BMI>22 kg/m^(2),4.3 vs.4.41 mm,and 41.66 vs.44.86 mm^(3))(P>0.05).The individualized volume CT dose index(CTDI_(vol)),the size specific dose estimate and effective dose were significantly reduced in the LDCT group compared with the SDCT group(all P<0.0001).This was especially true for dose-sensitive organs such as the lung(for BMI<22 kg/m^(2),2.62 vs.12.54 mSV,and for BMI>22 kg/m^(2),1.62 vs.9.79 mSV)and the breast(for BMI<22 kg/m^(2),2.52 vs.10.93 mSV,and for BMI>22 kg/m^(2),1.53 vs.9.01 mSV)(P<0.0001).Conclusion:These results suggest that with the increases in image noise,LDCT and SDCT exhibited a comparable image quality and sensitivity.The LDCT protocol for chest scans may reduce radiation exposure by about 80% compared to the SDCT protocol.
