Secondary cytoreductive surgery significantly lengthened survival for patients with recurrent epithelial ovarian cancer. Patients with ascites at disease recurrence, however, were not suitable for aggressive secondary surgery, and redebulking surgery for those with residual disease of >1.0 cm after primary operation should be considered prudently.

Purpose Surgical stress promotes tumor metastasis. Interleukin (IL)-17 plays a pivotal role in cancer progression, and high IL-17 expression predicts poor prognosis of non-small-cell lung cancer (NSCLC). Lidocaine may exert tumor-inhibiting effects. We hypothesize that intravenous lidocaine attenuates surgical stress and reduces serum IL-17 levels during video-assisted thoracic surgery (VATS) for NSCLC. Methods This randomized, double-blind, placebo-controlled trial included 60 early-stage NSCLC patients undergoing VATS, into a lidocaine group (n = 30; intravenous lidocaine bolus 1.0 mg/kg, and 1.0 mg/kg/h until the end of surgery) or a normal saline control group (n = 30). The primary outcome was serum IL-17 level at 24 hours postoperatively. The secondary outcomes included serum IL-17 level at the time of post-anesthesia care unit (PACU) discharge, serum cortisol level at PACU discharge and postoperative 24 hours, pain scores (0–10) from PACU discharge to 48 hours postoperatively, incidences of postoperative nausea and vomiting, dizziness, and arrhythmia during 0–48 hours postoperatively, and 30-day mortality. Long-term outcomes included chemotherapy, cancer recurrence, and mortality. Results The lidocaine group had lower serum IL-17 at 24 hours postoperatively compared with the control group (23.0 ± 5.8 pg/mL vs 27.3 ± 8.2 pg/mL, difference [95% CI] = −4.3 [−8.4 to −0.2] pg/mL; P = 0.038). The lidocaine group also had reduced serum IL-17 (difference [95% CI] = −4.6 [−8.7 to −0.5] pg/mL), serum cortisol (difference [95% CI] = −37 [−73 to −2] ng/mL), and pain scores (difference [95% CI] = −0.7 [−1.3 to −0.1] points) at PACU discharge. During a median follow-up of 10 (IQR, 9–13) months, 2 patients in the lidocaine group and 6 patients in the control group received chemotherapy, one patient in the control group had cancer recurrence, and no death event occurred. Conclusion Intravenous lidocaine was associated with reduced serum IL-17 and cortisol following VATS procedures in early-stage NSCLC patients. Trial Registration ChiCTR2000030629.

The purpose of this study was to investigate the clinical features of patients with epithelial ovarian cancer (EOC) that are initially categorized as extraabdominal adenocarcinoma of unknown primary. Twenty-five patients with EOC, who were treated in the Cancer Hospital of Shanghai Medical University from January 1986 to December 1997, and manifesting as extraperitoneal or liver parenchyma metastases at the time of presentation without detectable ovarian tumors, were retrospectively studied. Sixteen patients (64%) were optimally surgical debulked. When compared with 52 other women with stage IV EOC, 20 patients who initially sought treatment for extraabdominal metastases experienced a better prognosis, with an estimated median survival of 24 months versus 10 months (p = 0.0427). The median survival was 30 months in patients with pleural effusion or supraclavicular lymph node metastases versus 19 months in those with spread to other sites (p = 0.0264). The prognosis of such cases, mainly for those with supraclavicular lymphadenopathy or malignant pleural effusion, is better than that for other stage IV EOC patients, probably because most of the patients who initially had distant metastases were generally in condition that permitted aggressive surgery or multicycle chemotherapy.

Background: Metagenomic next-generation sequencing (mNGS), with its comprehensiveness, is widely applied in microbiological diagnosis. Etiological diagnosis is of paramount clinical importance in patients with skin and soft tissue infections (SSTIs). However, the clinical application of mNGS in SSTIs is relatively less studied. Materials and methods: From April 1, 2017 to December 31, 2019, 96 SSTI cases were collected. The positive rates of pathogens detected by mNGS and culture were compared by analyzing tissue samples, pus, swabs, and/or interstitial fluids obtained from the infected parts. Modification of the antibiotic treatment strategy due to mNGS was also assessed. Results: The sensitivity of mNGS for detecting pathogens in SSTI cases was superior to that of culture testing (67.7% vs 35.4%; p < 0.01). Significantly higher identification rates for viruses (10.4% vs 0.0%; p < 0.01) and anaerobes (11.5% vs 1.0%; p < 0.01) were obtained with mNGS compared to culture. Of note, rare pathogens such as Vibrio vulnificus and Bartonella henselae were also detected by mNGS. Importantly, the proportion of multi-pathogen SSTIs detected by mNGS was higher than that of multi-pathogen SSTIs detected by culture (16.7% vs 6.3%; p = 0.035). The rate of targeted antibiotic treatment was significantly higher in mNGS-positive cases than in mNGS-negative cases (41.7% vs 3.8%; p < 0.01). In culture-negative and mNGS-positive cases, the improvement rate was higher than that in mNGS-negative cases, but this was not statistically significant (75.0% vs 73.1%; p = 0.864). Conclusions: mNGS is a promising tool for the etiological diagnosis of SSTIs, particularly in identifying viruses, anaerobes, and multi-pathogen infections. The application of mNGS testing in clinical practice could change antibiotic treatment strategies and partly benefit clinical outcomes.

Background: Metagenomic next-generation sequencing (mNGS) is widely applied in the etiological diagnosis of infectious diseases. However, the clinical practice of mNGS in infective endocarditis (IE) is relatively less studied. This research aimed to assess the etiological diagnostic value of valve mNGS in IE.Methods: We retrospectively analyzed 49 IE patients who underwent cardiac valve surgery in Zhongshan Hospital, Fudan University, Shanghai from 1 June 2018 to 30 November 2020. Among these IE patients, 28 were culture positive and 21 were culture negative. The culture results of the culture-positive IE patients were set as gold standard to assess the sensitivity and specificity of valve mNGS in the etiological diagnosis of IE. We studied the positive detection rate of pathogens by valve mNGS among the culture-negative IE patients. During the same period, we also collected the resected valves of 8 patients with non-infective valvular diseases for mNGS as negative controls.Results: The valve mNGS results of the culture-positive IE patients were the exact same as their culture results. Both the sensitivity and specificity of valve mNGS were 100%. The positive detection rate of pathogens by valve mNGS was 100% among the culture-negative IE patients. The stringent mapped reads number of genera (SMRNG), relative abundance of genera, stringent mapped reads number of species (SMRN), relative abundance of species, and coverage rate of valve mNGS results were significantly higher in culture-positive IE participants than in culture-negative IE participants. The valve mNGS results of the 8 participants with non-infective valvular diseases were all negative.Conclusions: Valve mNGS is a promising technology for the etiological diagnosis of IE, especially culture-negative IE, and it may be used to guide precise antibiotic treatment after surgery.
