ObjectiveTo analyze the value of internal mammary lymph node biopsy via intercostal space in staging and adjuvant therapy of breast cancer. MethodsThe clinical data of 305 breast cancer patients received any kind of radical mastectomy from may 2003 to January 2014 in the Jinan Military General Hospital of PLA were analyzed retrospectively. The patient age, axillary lymph node, and internal mammary lymph node status were integrated to investigate the changing of staging and postoperative adjuvant therapy of the breast cancer. ResultsThese 305 patients were divided into neoadjuvant chemotherapy group and non-neoadjuvant therapy group. There were 67 patients in the neoadjuvant chemotherapy group, including 45(67.2%) patients with axillary lymph node positive, 23(34.3%) patients with internal mammary lymph node positive. There were 23(34.3%) patients who had a change of pathology lympy node (pN) staging and 8(11.9%) patients who had a change of the pTNM staging. Meanwhile, there were 238 patients in the non-neoadjuvant chemotherapy group, including 155(65.1%) patients with axillary lymph node positive, 30(12.6%) patients with internal mammary node positive. There were 30(12.6%) patients who had a change of the pN staging and 23(9.66%) patients who had a change of the pTNM staging. There was a significant difference in the metastasis rate of the internal mammary lymph node (χ2=15.7, P < 0.05) or the changing ratio of the pTNM staging (χ2=5.3, P < 0.05) in two groups. ConclusionsInternal mammary lymph node status could affect pN staging of breast cancer, so do the pTNM staging (TNM, pathology tumor, lymph node, metastasis). The internal mammary lymph node status could guide the postoperative adjuvant radiative therapy by reducing excessive treatment of the internal mammary lymph node area, also could enhance the individual accurate therapy.

Methods From January to November 2009, Fifty-two patients with tuberculous pleurisy were randomly divided into conventional group (40 patients) and pleural biopsy group (12 patients), in order to compare the results of conventional diagnostic methods and tuberculous biopsy methods in the diagnosis of tuberculous pleurisy. Results Conventional group was unable to obtain the final bacteriological, pathological basis which obstained the diagnostic rate of 0, but in the pleural biopsy group, five patients got diagnosis basing on bacteriological and pathology tests, and the diagnostic rate was 41.7%;there was significant difference when compared the results of the two groups (Plt;0.05). The average diagnosis time were 60 days in the conventional group, and five days in the pleural biopsy group, there was significant difference when compared the results of the two groups (Plt;0.05). Pleural biopsy group had no complications occurred. Conclusion Pleural biopsy methods in the diagnosis of tuberculous pleurisy are of great value.
ObjectiveIn order to improve the levels of clinical diagnosis and treatment of differentiated thyroid cancer, the research status and progress of blood markers of differentiated thyroid cancer in recent years were reviewed.MethodThe literatures about blood markers and liquid biopsy of differentiated thyroid cancer at home and abroad in recent years were searched and summarized.ResultsThyroglobulin and thyroglobulin antibody were the most commonly used for markers of differentiated thyroid cancer. The application value of blood markers such as microRNA and long non-coding RNA in the diagnosis, treatment and follow-up of differentiated thyroid cancer had also been found.ConclusionBecause of the advantages of high specificity, high sensitivity, and no-invasion, blood markers are useful indicators to help improve the diagnosis of thyroid cancer patients and monitor the disease progression and recurrence in the future.
ObjectiveTo explore the influence of sentinel lymph node (SLN) status on the prognosis of elderly breast cancer patients ≥70 years old, and to screen patients who may be exempted from sentinel lymph node biopsy (SLNB), so as to guide clinical individualized treatment for such patients. MethodsA retrospective analysis was made on 270 breast cancer patients aged ≥70 years old who underwent SLNB in the Affiliated Hospital of Southwest Medical University from 2012 to 2021. The clinicopathological characteristics of the total cases were compared according to the status of SLN. Kaplan-Meier method was used to draw the survival curve, and the influence of SLN status on the overall survival (OS) time, local recurrence (LR) and distant metastasis (DM) of patients were analyzed, and used log-rank to compare between groups. At the same time, the patients with hormone receptor (HR) positive were analyzed by subgroup. The differences between groups were compared by single factor χ2 test, and multivariate Cox regression model was used to analyze and determine the factors affecting OS, LR and DM of patients. ResultsThe age of 270 patients ranged from 70 to 95 years, with a median age of 74 years. One hundred and sixty-nine (62.6%) patients’ tumor were T2 stage. Invasive ductal carcinoma accounted for 83.0%, histological gradeⅡ accounted for 74.4%, estrogen receptor positive accounted for 78.1%, progesterone receptor positive accounted for 71.9%, and human epidermal growth factor receptor 2 negative accounted for 83.3%. The number of SLNs obtained by SLNB were 1-9, and the median was 3. SLN was negative in 202 cases (74.8%) and positive in 68 cases (25.2%). Thirty-five patients (13.0%) received axillary lymph node dissection. There was no significant difference in LR between the SLN positive group and the SLN negative group (P>0.05), but the SLN negative group had fewer occurrences of DM (P=0.001) and longer OS time (P=0.009) compared to the SLN positive group. The results of univariate and multivariate analysis suggest that the older the patient, the shorter the OS time and the greater the risk of DM. Analysis of HR positive subgroups showed that SLN status did not affect patient survival and prognosis, but age was still associated with poor OS time and DM. ConclusionsFor patients with invasive ductal carcinoma of breast in T1-T2 stage, HR positive, clinical axillary lymph nodes negative, and age ≥70 years old, SLNB may be exempted. According to the patient’s performance or tumor biological characteristics, patients who need systemic adjuvant chemotherapy may still consider SLNB.
ObjectiveTo improve clinicians' awareness of cryptogenic organizing pneumonia (COP).MethodsThirty-three inpatients with COP, who had been diagnosed by pathology in Nanjing Drum Tower Hospital during January 2013 to December 2016 were collected. Their clinical manifestations, laboratory tests and imaging data were reviewed and analyzed retrospectively.ResultsThirty-three cases consisted of 18 males and 15 females, and the mean age was (58.7±13.5) years old. Most patients had subacute or insidious onset. The common symptoms were cough, fever, shortness of breath and chest tightness. About half of patients revealed inspiratory crackles or velcroes. Autoantibodies and anti-neutrophil cytoplasmic antibodies were negative. High-resolution computerized tomography findings of COP included bilateral patchy areas of air-space consolidation that showed predominantly subpleural or peri-bronchovascular distribution, focal nodules, enlarged hilar or mediastinal lymph nodes and pleural effusion. 25 patients were treated with glucocorticoid, 6 with macrolid, and 2 were only followed up without drug treatment.ConclusionsClinical manifestations, laboratory tests and imaging features are important clues to diagnose COP. Diagnosis depends on pathology. Meanwhile, definite pathogen and potential underlying diseases must be excluded.
ObjectiveTo explore the clinical application of the comprehensive guidance technologies, such as cone beam computed tomography (CBCT), virtual bronchoscopic navigation (VBN), and superimposed high-frequency jet ventilator for respiratory control in the biopsy of peripheral pulmonary nodules (PPNs). MethodsThe clinical information of 3 patients with PPNs diagnosed by CBCT combined with VBN and superimposed high frequency superposition jet ventilator in Shanghai Changhai Hospital were retrospectively analyzed. Results Clinical data of 3 patients were collected. The average diameter of PPNs was (25.3±0.3) mm with various locations in left and right lung. The first nodule was located in the apex of the left upper lung, and the biopsy was benign without malignant cells. The lesion was not enlarged during the 5-year follow-up. The second one was located in the left lingual lung, and the postoperative pathology was confirmed as mucosa-associated lymphoma. The third one was located in the anterior segment of the right upper lung. After the failure of endobronchial procedure, percutaneous PPNs biopsy under CBCT combined with VBN was performed, and the pathological diagnosis was confirmed as primary lung adenocarcinoma. Postoperative pneumothorax complication occurred in the third patient with right lung compression rate approximately 20%. ConclusionsThe application of CBCT, combined with VBN and the superimposed high frequency jet ventilator for respiratory control can potentially improve the accuracy and safety in the diagnosis of PPNs. Multi-center clinical trials are needed to verify its further clinical application.
Objective To investigate the feasibility and operation effect of endoscopic sentinel lymph node biopsy （SLNB） in breast cancer. Methods The data of 410 breast cancer patients who underwent SLNB （including 107 patients with endoscopy and 303 with open operation） were analyzed in our hospital from January 2009 to March 2012. SLNB was performed by using methylene blue staining or the combination of methylene blue and 99Tcm-sulfur colloid tracing. Results The successful rate of SLN detection with methylene blue and 99Tcm-sulfur colloid tracing was 94.56% （139/147） in open operation group and 94.25% （82/87） in endoscopy group. The successful rate of SLN detection with methylene blue was 88.46% （138/156）in open operation group and 85.00% （17/20） in endoscopy group. The mean of detected SLN number with combined method or methylene blue was 1.90/1.98 in open operation group and 1.91/1.82 in endoscopy group respectively. SLN-positive rate was 22.30% （31/139） and 25.36% （35/138） in open operation group， and 19.51% （16/82） and 23.53% （4/17） in endoscopy group， respectively. The rate of subcutaneous effusion in endoscopy group was higher than that in open operation group （P=0.001）, but other postoperative complications presented no significant difference. Conclusions Endoscopic SLNB can obtain the similar safety and the clinical efficacy with traditional SLNB， but superior cosmetic effect. So it is worthy of clinical application in breast cancer.
