RESUMO
Objective:To evaluate the value of 18F-FDG PET/CT in the diagnosis and treatment of primary breast lymphoma (PBL). Methods:Clinical data and 18F-FDG PET/CT imaging data of 6 patients (all females, age 46-79 years) with pathologically diagnosed primary breast diffuse large B cell lymphoma (PB-DLBCL) in Xishan People′s Hospital of Wuxi City and Affiliated Hospital of Jiangnan University from July 2015 to October 2021 were analyzed retrospectively. A total of 10 18F-FDG PET/CT scans were done for primary staging (6 scans of 6 patients), evaluation of treatment response (3 scans of 2 patients), and recurrence detection (1 scan of 1 patient). 18F-FDG PET/CT image analysis was performed qualitatively (visually) and semi-quantitatively (SUV max). Treatment response was evaluated by Deauville scores. Results:All 6 patients were diagnosed pathologically as PB-DLBCL (3 patients by core needle biopsy, 3 patients by biopsy after lumpectomy). All 6 patients were staged using baseline 18F-FDG PET/CT before chemotherapy. For 3 patients diagnosed by core needle biopsy, baseline 18F-FDG PET/CT showed unilateral breast lesion with high FDG uptake (SUV max: 23.0, 52.9, and 33.6). For 3 postoperative patients, baseline 18F-FDG PET/CT showed flocculent soft tissue density in the operative area with low FDG uptake (SUV max: 3.4, 2.2 and 2.0). Patient No.2 showed a large left breast mass with left axillary lymph node involvement by baseline PET/CT, and multiple nodular uptakes in bilateral breast (Deauville score of 4) after 4 courses of chemotherapy and negative result (Deauville score of 1) after 3 courses of new chemotherapy regimens by PET/CT. Patient No.4 showed right breast lesion and right axillary lymph nodes by routine preoperative imaging examination, but left breast lesion by postoperative PET/CT. According to the results of 18F-FDG PET/CT, patient No.4 was with complete response (Deauville score of 1) after treatment, but recurrence (Deauville score of 5) occurred after 7 months follow-up. Conclusion:18F-FDG PET/CT can play an important role in every step of management (diagnosis and staging, treatment response evaluation and detection of recurrence) in patients with PB-DLBCL.
RESUMO
Objective:To investigate the predictive value of postoperative C-reactive protein for serious complications after Da Vinci robotic surgical system radical gastrectomy of gastric cancer.Methods:The retrospective case-control study was conducted. The clinicopathological data of 298 patients with advanced gastric cancer who underwent Da Vinci robotic surgical system radical gastrectomy in the 940th Hospital of Joint Logistics Support Force of Chinese People's Liberation Army from January 2017 to June 2019 were collected. There were 253 males and 45 females, aged from 24 to 86 years, with a median age of 60 years. Of the 298 patients, 275 cases underwent no serious postoperative complications and 23 cases underwent serious postoperative complications. Observation indicators: (1) serious postoperative complications; (2) analysis of risk factors for serious postoperative complications after Da Vinci robotic surgical system radical gastrectomy of gastric cancer; (3) performance evaluation of the predictive indicators. Measurement data with skewed distribution were represented as M(range). Count data were described as absolute numbers and comparison between groups was conducted using the chi-square test or Fisher exact probability. Comparison of ordinal data was conducted using the rank sum test. Univariate analysis was conducted using the chi-square test. Multivariate analysis was conducted using Logistic regression model. The receiver operating characteristic curve was drawn and the area under curve (AUC) was used to compare and estimate the efficiency of diagnostic criteria. The value of Youden index was used to determine the optimal cut-off point. Results:(1) Serious postoperative complications: of the 298 patients, 23 cases underwent complications classified ≥grade Ⅲa of Clavien-Dindo classifica-tion, including 10 cases with grade Ⅲa complications, 7 cases with grade Ⅲb complications, 4 cases with grade Ⅳa complications, 1 case with grade Ⅳb complications and 1 case with grade Ⅴ complications. (2) Analysis of risk factors for serious postoperative complications after Da Vinci robotic surgical system radical gastrectomy of gastric cancer. Results of univariate analysis showed that operation time, indicators of C-reactive protein concentration and neutrophil count at post-operative day 1, and indicators of C-reactive protein concentration, white blood cells count, neutrophil count and platelet count at postoperative day 3 and pathological stage were related factors affecting serious complications for advanced gastric cancer after Da Vinci robotic surgical system radical gastrectomy ( χ2=7.671, 4.504, 5.045, 48.293, 9.575, 15.436, 13.731, 9.537, P<0.05). Results of multivariate analysis showed that the operation time ≥250 minutes, the concentration of C-reactive protein at postoperative day 3 ≥16.65 mg/dL, the neutrophil count at postoperative day 3 ≥8.167×10 9/L, the platelet count at postoperative day 3 ≥218×10 9/L and the pathological stage of tumor as stage Ⅱ and stage Ⅲ were independent risk factors affecting serious complications for advanced gastric cancer after Da Vinci robotic surgical system radical gastrectomy ( odds ratio=3.721, 16.084, 6.056, 6.893, 12.455, 95% confidence interval: 1.032-13.421, 4.657-55.547, 1.073-34.163, 1.798-26.423, 1.338-115.930, P<0.05). (3) Performance evaluation of the predictive indicators: the C-reactive protein concentration at postoperative day 3 was a high-performance predictor with the AUC as 0.851 (95% c onfidence interval: 0.780-0.921, P<0.05) and neutrophil count and platelet count at postoperative day 3 were low-performance predictors with the AUC as 0.659 and 0.666 (95% confidence interval: 0.570-0.748 and 0.581-0.750, P<0.05). Conclusion:The C-reactive protein concentration ≥16.65 mg/dL at postoperative day 3 is a high performance predictive indicator for serious complications after Da Vinci robotic surgical system radical gastrectomy of gastric cancer.
