Abstract Peripheral primitive neuroectodermal tumors (PNETs) constitute very rare and aggressive malignancies. To date, there are no standard guidelines for management of peripheral PNETs due to the paucity of cases arising in various body sites. Therapeutic approach is derived from Ewing sarcoma family, which currently remains multimodal. Our study retrospectively analyzed 86 PNET patients from February 1, 1998 to February 1, 2018 at Peking Union Medical College Hospital with an additional 75 patients from review of literature. The clinicopathologic and treatment plans associated with survival was investigated. Surgery, chemotherapy, female sex, small tumor size, no lymph node metastasis, R0 surgical resection, (vincristine + doxorubicin + cyclophosphamide)/(isophosphamide + etoposide) regimen, and more than 10 cycles of chemotherapy were associated with improved overall survival in univariate analysis. Surgery, more than 10 cycles of chemotherapy, and small tumor size were independent prognostic factors for higher overall survival. Our data indicates that multimodal therapy is the mainstay therapeutic approach for peripheral PNET.

AbstractBackgroundThe aim of the study was to assess the primary efficacy of robot-assisted microwave ablation and compare it to manually guided microwave ablation for percutaneous ablation of liver malignancies.Patients and methodsWe performed a retrospective single center evaluation of microwave ablations of 368 liver tumors in 192 patients (36 female, 156 male, mean age 63 years). One hundred and nineteen ablations were performed between 08/2011 and 03/2014 with manual guidance, whereas 249 ablations were performed between 04/2014 and 11/2018 using robotic guidance. A 6-week follow-up (ultrasound, computed tomography and magnetic resonance imaging) was performed on all patients.ResultsThe primary technique efficacy outcome of the group treated by robotic guidance was significantly higher than that of the manually guided group (88% vs. 76%; p = 0.013). Multiple logistic regression analysis indicated that a small tumor size (≤ 3 cm) and robotic guidance were significant favorable prognostic factors for complete ablation.ConclusionsIn addition to a small tumor size, robotic navigation was a major positive prognostic factor for primary technique efficacy.

e21059 Background: Traditionally, larger tumor size and lymph node (LN) involvement have been considered independent predictors of mortality in melanoma. We aimed to characterize the interaction between tumor size and LN involvement in melanoma specific mortality. In particular, we evaluated whether very small tumor size represented a particularly aggressive disease variant compared with larger LN-positive melanoma. Methods: Using Surveillance, Epidemiology and End Results registry data, we identified 57,223 patients (aged 18-85 years) diagnosed between 1998 and 2012 with histologically confirmed nonmetastatic melanoma treated with surgery. Primary study variables were tumor size, LN involvement, and their corresponding interaction term. Kaplan-Meier methods, adjusted Cox proportional hazards models with interaction terms were performed. Potential confounders included age, sex, year of diagnosis, marital status and number of LN dissected. Results: Median follow-up was 48 months. In multivariable analysis, there was significant interaction between tumor size and LN involvement ( P < 0.0001) using the likelihood ratio test and Wald test. In the absence of LN involvement (n = 54,922), the hazard ratio (HR) increased monotonically with increasing tumor size. Among patients with LN involvement (n = 2,301), using the smallest tumors as the reference group, hazard ratio of cancer specific mortality decreased unexpectedly in 0.01-1.00mm tumors (HR 0.61, p = 0.022) and 1.01-2.00mm tumors (HR 0.58, p = 0.007), and reached to a similar level in tumors sized 2.01-4.00mm (HR 0.81, p = 0.280), and subsequently increased in tumors sized larger than 4.00mm (HR 1.57, p = 0.016). Conclusions: In LN positive melanoma, very small tumors may predict for higher mortality compared with larger tumors. These results should be validated in future database studies. Table.

Abstract Background IL34 involves in host immunity regulated carcinogenesis. Alpha-fetoprotein (AFP) is related to the development of HCC. We explored if combination of IL-34 and APF could improve the diagnostic value in HBV related hepatocellular carcinoma (HBVHCC). Methods Serum was obtained from HBV patients or healthy control. Liver tissue was obtained from liver biopsy in CHB, HBV related cirrhosis patients or curative resection in HBVHCC patients. Serum IL34 and MCSF were measured. Hepatic IL34, MCSF and CD68+ tumor associate macrophages (TAMs) were determined. Results Serum IL34 was 1.7, 1.3 or 2.3-fold higher in HBVHCC than that of CHB, HBV related cirrhosis, or healthy control, which was inhibited following transhepatic arterial chemoembolization (TACE) in HBVHCC patients. Intrahepatic IL34 was higher in HBVHCC than that of the other three groups. Intra-hepatic IL34 was associated with high HBVDNA, HBeAg−, poor differentiation and small tumor size of HBVHCC patients. Intra-hepatic TAMs in HBVHCC were increased 1.7 or 1.3-fold, compared to that from CHB or HBV-cirrhosis patients. Intra-hepatic TAMs were associated with high HBVDNA, high tumor differentiation, small tumor size, abnormal AFP and more tumor number. AFP plus serum IL-34, showed the highest AUC (0.837) with sensitivity (0.632) and highest specificity (0.931), suggesting that AFP plus IL-34 enhances the reliability for prediction of the development of HBVHCC among CHB patients. Conclusions Circulating and intra-hepatic IL34 was upregulated gradually in HBV disease progression from CHB, cirrhosis and HCC. IL-34 may be used as a diagnostic biomarker and potential therapeutic target for the management of HBVHCC.
