Objective To explore the imaging features, clinical outcome, and prognosis of indeterminate pulmonary nodules (IPN) in patients with high-grade soft tissue sarcoma. Methods A retrospective study of 82 patients with high-grade soft tissue sarcoma who have IPNs. The clinical characteristics, imaging features of IPN, and survival of patients were analyzed with statistical software. Results The IPN size of 82 patients was 6.453±0.864 mm. IPN diameter, shape, density, and nodule discovery interval may be CT imaging features related to malignancy tendency. Age (HR=1.047, 95%CI: 1.007-1.088) and interval between each nodule discovery (HR=3.194, 95%CI: 1.052-9.694) are independent factors that affect the survival of patients with malignant IPN. Conclusion The imaging features of chest CT may provide important guidance for determining the nature and survival prognosis of benign and malignant nodules.

Objective:To evaluate the efficacy of Yiqi Yangyin Jiedu Decoction in the treatment of patients with pulmonary nodules and qi-yin deficiency syndrome after early lung cancer surgery.Methods:Randomized controlled trial was conducted. A total of 76 patients with lung nodules and qi-yin deficiency syndrome after early lung cancer surgery at the Oncology Department of Longhua Hospital Affiliated to Shanghai University of Traditional Chinese Medicine from March to September 2020 were selected and randomly divided into two groups using a random number table method, with 38 cases in each group. The control group received symptomatic treatment, while the treatment group took Yiqi Yangyin Jiedu Decoction from the first day after enrollment. Both groups were treated for 6 months and followed up for 2 years. TCM syndrome scores before and after treatment were evaluated; the patients' activity status was evaluated using the Eastern Oncology Collaborative Group Activity Status (ECOG PS) score in the United States, and electrochemiluminescence was used to detect carcinoembryonic antigen (CEA) and neuron specific enolase (NSE). Flow cytometry was used to detect the percentage of T lymphocyte subsets CD3 +and CD4 +, and ELISA was used to detect TGF-β Horizontal. The patients' weight was recorded and their weight changes after treatment were observed. Adverse reactions during treatment were observed and recorded, the efficacy of TCM syndromes and pulmonary nodules was evaluated. Results:During the observation period, one case was lost to follow-up in the treatment group and three cases were lost to follow-up in the control group. Finally, 37 cases in the treatment group and 35 cases in the control group completed the observation. After the treatment, the panting (0.27±0.07 vs. 0.68±0.12, t=17.66), spontaneous sweating and night sweating (0.16±0.16 vs. 0.79±0.16, t=16.55) score of the treatment group were lower than those in the control group ( P<0.01); insomnia (0.15±0.08 vs. 0.54±0.13, t=15.52) score of the control group was lower than that of the treatment group ( P<0.01). The effective rate of TCM syndrome in treatment group was 81.08% (30/37), higher than 54.29% (19/35) in control group ( Z=-2.00, P=0.040). After the treatment, the ECOG PS score stability rate in the treatment group was 89.19% (33/37), higher than 82.86% (29/35) in control group, without statistical significance ( χ2=0.19, P>0.05). The increase and stable rate of body weight was 88.10% (32/37) in treatment group and 62.86% (22/35) in control group ( χ2=5.36, P<0.05). After 2-year follow-up, the control rate of pulmonary nodules in the treatment group was 91.89% (34/37), while in the control group it was 65.71% (23/35). The difference between the two groups was statistically significant ( χ2=7.47, P<0.01). After the treatment, the level of NSE [(12.54±2.52)ng/L vs. (13.85±2.71)ng/L, t=-2.12], TGF-β [(218.38±102.63)ng/L vs. (301.24±193.69)ng/L, t=-2.29] in treatment group were lower than those in the control group ( P<0.05), and the level of CD3 +T cells [(70.60±7.90)% vs. (65.99±9.27)%, t=2.32] in treatment group was higher than that of the control group ( P<0.05). Conclusion:Yiqi Yangyin Jiedu Decoction can delay the development of pulmonary nodules in patients after early lung cancer surgery, increasing the body weight of patients, relieving the TCM syndromes and improve the immune function of patients, with the potential to prevent and treat the occurrence and development of early lung cancer.

Objective To investigate the characteristics and clinicopathology of v-raf murine sarcoma viral oncogene homolog Bl(BRAF)V600E mutations in papillary thyroid carcinoma(PTC)in Air Force flight personnel.Methods Data of cases and test results of BRAF V600E mutation were collected from Air Force aviators pathologically diagnosed with PTC.A univariate analysis of the relationship between BRAF V600E mutations and clinicopathologic features was performed.Results The overall rate of BRAF V600E mutations among 55 PTC flight crew members was 70.91％.The univariate analysis showed that the number of lymph node metastases in the BRAF V600E mutated group was larger than in the BRAF V600E unmutated group,and the proportion of BRAF V600E mutations in flight crews at intermediate risk of recurrence was higher than that in those at low risk of recurrence(P＜0.05).The presence or absence of BRAF V600E mutations did not affect the results of medical evaluation of PTC in flight personnel.Conclusion The rate of PTC BRAF V600E mutations in Air Force flight crews is similar to that of the general Chinese population.BRAF V600E mutations are associated with an increased number of lymph node metastases and risk of recurrence,and follow-up is recommended for flight personnel with PTC,especially those with BRAF V600E mutations.

Objective:To explore the consistency between modified 12+ X prostate biopsy under transrectal interventional ultrasound and postoperative Gleason score in prostate cancer patients.Methods:A retrospective study was conducted on 312 patients diagnosed with prostate cancer and underwent radical resection at Zhongshan People′s Hospital from January 2020 to December 2022. All patients underwent modified 12+ X prostate biopsy and prostate system biopsy under transrectal interventional ultrasound before surgery. Using the Gleason score of postoperative pathological specimens as the " gold standard", the detection rates of prostate cancer and clinically significant prostate cancer using modified 12+ X prostate biopsy and prostate system biopsy under transrectal interventional ultrasound were compared, and the consistency between the two methods alone or in combination and postoperative Gleason score was compared.Results:Among 312 patients, the positive detection rate of the improved 12+ X puncture biopsy combined with the system puncture biopsy was significantly higher than that of the individual detection (95.51% vs 80.77% vs 76.92%), with a statistically significant difference ( P<0.05). The improved 12+ X puncture biopsy combined with system puncture biopsy showed a clinically significant higher detection rate of prostate cancer in positive patients compared to the two tests alone (94.63% vs 77.78% vs 80.00%), with a statistically significant difference ( P<0.05). There was no statistically significant difference in the detection rate of clinically significant prostate cancer among patients who missed diagnosis, either alone or in combination with biopsy ( P>0.05). The upgrade rate of Gleason score after prostate improvement 12+ X puncture biopsy (25.00%) was significantly lower than that of prostate system puncture (44.17%), which was significantly higher than combined puncture biopsy (11.74%), with a statistically significant difference ( P<0.05). After 312 patients received combined puncture biopsy, urinary retention was found in 14 cases (4.49%), hematuria in 30 cases (9.62%), fever in 28 cases (8.97%), and blood in stool in 18 cases (5.77%). After symptomatic treatment, they basically improved within 3 days after puncture. Conclusions:The combination of modified 12+ X prostate biopsy with systematic biopsy under transrectal interventional ultrasound can improve the detection rate of prostate cancer, and has good consistency with the postoperative Gleason score of prostate cancer patients, which has good clinical application value.

Objective:To explore the incidence, clinical characteristics, imaging features, clinical outcome and prognosis of indeterminate pulmonary nodules (IPN) in patients with osteosarcoma.Methods:A total of 69 patients of osteosarcoma with IPN in lung treated in the Bone tumor Center of Eastern Theater General Hospital from January 2011 to January 2021 were collected retrospectively, there were 47 males and 22 females, with a median age of 19 years old (range 7-60 years old). The clinical characteristics including disease-free interval, the chemotherapy response, with recurrence/non-pulmonary, IPN presence before / during / after chemotherapy and imaging features of IPN including number of IPN, location of IPN, density of IPN, boundary clarity of IPN and outcome. The patients were divided into the metastasis pulmonary nodules group and the benign nodules group according to the final outcome of IPN. Further, χ 2 test was performed for comparison of the clinical and imaging characteristics between the two groups. The survival of patients was counted and the correlation between single factor and survival was compared by Kaplan-Meier test, and multivariate survival analyses were performed using Cox proportional hazards regression models. Results:Sixty-nine cases occurred IPN in 211 patients with osteosarcoma, with an incidence of 32.7%. Of the 69 patients, 45 patients (65.2%) with IPN were diagnosed as metastases, and 24 patients (34.8%) with IPN were diagnosed as benign nodules. Follow-up length ranged from 1 to 124 months, with the median follow up time 43 months. To the end of follow-up, 41 patients (59.4%) remained alive and 28 patients (40.6%) had died. The median survival time was 41.0 (20.0, 65.0) months and the median survival time after diagnosis of IPN was 25.0 (10.0, 43.0) months. There were significant differences in lung nodule density ( P<0.001), boundary ( P=0.002), history of recurrence/extra-pulmonary metastasis ( P=0.023) and chemotherapeutic effect ( P<0.001) between the metastasis pulmonary nodules group and the benign nodules group. Multivariate survival analysis showed that chemotherapeutic effect was an independent factor affecting the overall survival of patients [ HR=0.048, 95% CI (0.01, 0.26)]. Boundary definition [ HR=0.12, 95% CI (0.02, 0.93)] and chemotherapeutic effect [ HR=0.06, 95% CI (0.01, 0.29)] were independent factors influencing survival after diagnosis of IPN. Conclusion:Osteosarcoma patients with IPN have a poor prognosis. The poor effect of chemotherapy is an independent risk factor for the overall survival time of those patients and the survival time after diagnosis of IPN. The boundary definition of IPN is an independent risk factor for the survival time after diagnosis of IPN.

Objective:To analyze the value of peritumoral vascular invasion (PVI) on the prognosis of patients with osteosarcoma.Methods:A total of 232 patients with primary osteosarcoma from 2007 to 2016 were retrospectively analyzed, including 142 males and 90 females. The average age was 17.9±8.2 years (range, 3-39 years). There were 22 positive and 210 negative cases of PVI, 94 deaths and 138 survivals. Univariate survival analysis (Log-rank test and univariate Cox regression) was used to evaluate the effects of age, gender, PVI status, tumor location, surgical method, sensitivity to chemotherapy, and chemotherapy regimen on the prognosis of osteosarcoma. The indicators with statistically significant differences were included in the multivariate Cox regression model to finally determine the risk factors affecting the prognosis of osteosarcoma. The relationship between PVI status and 5-year survival and the incidence of recurrence or metastasis was evaluated using the Kaplan-Meier method.Results:All patients were followed up for 7.6±4.5 years (range, 0.1-15 years). The differences in sensitivity to chemotherapy (χ 2=9.52, P=0.002), choice of chemotherapy regimen (χ 2=8.87, P=0.012), choice of surgical modality (χ 2=13.50, P<0.001), tumor metastasis rate (χ 2=8.51, P=0.004) and mortality rate (χ 2=5.39, P= 0.020) of PVI positive group and PVI negative group had statistically significant differences. Univariate survival analysis was performed on 232 patients with osteosarcoma (gender, age, PVI status, site of tumor development, surgical modality, sensitivity to chemotherapy, and chemotherapy regimen). Indicators with statistically significant differences were included in a multifactorial Cox regression model. The results showed PVI positive [5-year survival rate: HR=2.02, 95% CI (1.61, 2.79), P=0.010; 5-year recurrence or metastasis rate: HR=2.25, 95% CI (1.55, 3.14), P<0.001], surgical procedure as amputation [5-year survival rate: HR=1.22, 95% CI (0.94, 1.78), P=0.037; 5-year recurrence or metastasis rate: HR=1.58, 95% CI (1.11, 2.23), P=0.026] and poor sensitivity to chemotherapy [5-year survival rate: HR=2.71, 95% CI (1.84, 3.98), P=0.001; 5-year recurrence or metastasis rate: HR=2.52, 95% CI (1.88, 3.45), P<0.001] was associated with poor prognosis. Kaplan-Meier curve showed that the 5-year survival rate of PVI positive group was 34%, which was lower than 68% of PVI negative group. The 5-year recurrence or metastasis rate was 72% in the PVI negative group, which was significantly higher than 38% in the PVI negative group ( P<0.05). Conclusion:The 5-year survival rate of PVI positive group was lower than that of PVI negative group, and the 5-year recurrence or metastasis rate was higher than that of PVI negative group. The presence of microvascular angiosarcoma plugs infiltrating the peritumoral tissue in surgical specimens of osteosarcoma after neoadjuvant chemotherapy is a useful indicator to assess the prognosis of patients with osteosarcoma.

Objective:To compare outcomes between standardized and misdiagnosis and mistreatment of osteosarcoma.Methods:A retrospective analysis of patients with high-grade osteosarcoma who received appropriate surgical treatment and chemotherapy (299 cases, control group) and those who were misdiagnosed (benign or infective) and received mistreatment (23 cases, study group) between January 2009 and December 2021. Gender, age, first operation mode, recurrence time, recurrence interval, metastasis time, metastasis interval, total survival time (months), survival status in the two group and tumor site reoperation mode in the study group were statistically analyzed. Further, chi-square test was performed for comparison of the clinical between two groups. The survival analysis was performed using Kaplan-Meier test and Log-rank test.Results:All the 322 patients were followed up. In the control group, the average follow-up time was 42 months (1-137 months), the average age was 24 years (3-80 years), male 184 cases, female 115 cases, and limb salvage rate was 85.3% (255/299). Seven patients underwent amputation, and the amputation rate was 17.7% (44/299). The recurrence rate was 8.4% (25/299), the average recurrence interval was 22.8 months (7-36 months), and the metastasis rate was 28.1% (85/299), the average metastasis time was 32.7 months (0-58 months). In the study group, the average of follow-up time was 30 months (9-117 months), the average age was 36 years (5-67 years), 17 males and 6 females. Among them, eleven patients were treated with limb salvage in the second stage, and the limb salvage rate was 47.8% (11/23). Seven patients underwent amputation, and the amputation rate was 30.4% (7/23). The recurrence rate was 26.1% (6/23), the average recurrence interval was 11 months (1-42 months), and the metastasis rate was 43.4% (10/23), the average metastasis time was 20.3 months (1-44 months). The 5-year survival rate was 50.7% in the study group and 56.1% in the control group. There was no significant difference between the two groups (χ 2=0.09, P=0.760). Conclusion:The overall prognosis of patients with high-grade osteosarcoma who receive active treatment after mistreatment is similar to that of patients with standardized treatment, but the recurrence and metastasis rate is higher, the recurrence time is earlier, and the amputation rate is higher.
