Abstract Background Medullary thyroid cancer (MTC) has more aggressive behavior and poor prognosis. Ultrasound (US) has facilitated the qualitative diagnosis of thyroid nodules, however, some MTC may be diagnosed as a benign nodule on ultrasound because ultrasound features of malignancy are lacking. The aim of the study was to investigate the association between ultrasound features and biological behavior of MTC. Methods Ultrasound findings and medical records of patients with MTC between Jan 2015 to Jun 2017 were retrospectively reviewed at Tianjin Medical University Cancer Institute and Hospital. MTC were categorized using modified TI-RADS classification, then were classified as “malignant” (m-MTC) or “US-low-suspicious” (l-MTC). We compared the biological behavior between the two groups, and further analyzed the risk factors for the recurrence. Results A total of 78 patients were enrolled, of which 55 m-MTC (70.5%) and 23 l-MTC (29.5%) were identified. The N staging of the m-MTC was significantly higher than that of l-MTC(P = 0.000). The preoperative serum Ct level in m-MTC were significantly higher than that of l-MTC(P = 0.035). Biochemical cure were more frequent in l-MTC than that of m-MTC (P = 0.002). Disease recurrence rates were 19.7% (14 of 71). Disease recurrence was more frequent in m-MTC than that of l-MTC (P = 0.013). Disease recurrence was positively associated with extrathyroid extension (P = 0.047), N staging (P = 0.003), preoperative serum Ct level (P = 0.009) and negatively associated with biochemical cure(P = 0.000). In multivariable Cox regression analysis, extrathyroid extension and biochemical cure were independent risk factors for recurrence of MTC. Conclusions L-MTC has a more indolent character than m-MTC. The extrathyroid extension and biochemical cure were independent risk factors for recurrence of MTC.

Abstract Background Postoperative complications are not rare in the elderly population after hepatectomy. However, predicting postoperative risk in elderly patients undergoing hepatectomy is not easy. We aimed to develop a new preoperative evaluation method to predict postoperative complications in patients above 65 years of age using biological impedance analysis (BIA). Methods Clinical data of 59 consecutive patients (aged 65 years or older) who underwent hepatectomy at our institution between 2017 and 2020 were retrospectively analyzed. Risk factors for postoperative complications (Clavien-Dindo ≥ III) were evaluated using multivariate regression analysis. Additionally, a new preoperative risk score was developed for predicting postoperative complications. Results Fifteen patients (25.4%) had postoperative complications, with biliary fistula being the most common complication. Abnormal skeletal muscle mass index from BIA and type of surgical procedure were found to be independent risk factors in the multivariate analysis. These two variables and preoperative serum albumin levels were used for developing the risk score. The postoperative complication rate was 0.0% with a risk score of ≤ 1 and 57.1% with a risk score of ≥ 4. The area under the receiver operating characteristic curve of the risk score was 0.810 (p = 0.001), which was better than that of other known surgical risk indexes. Conclusion Decreased skeletal muscle and the type of surgical procedure for hepatectomy were independent risk factors for postoperative complications after elective hepatectomy in elderly patients. The new preoperative risk score is simple, easy to perform, and will help in the detection of high-risk elderly patients undergoing elective hepatectomy.

BACKGROUND: Pilonidal sinus disease (PSD) is a chronic inflammatory disease of the sacrococcygeal area. Pilonidal sinus recurrence is a matter of concern to both patients and healthcare providers. OBJECTIVES: Estimate the rate of PSD recurrence in our center and identify any risk factors contributing to disease recurrence. DESIGN: Retrospective. SETTING: Tertiary care center in Riyadh. PATIENTS AND METHODS: All patients who underwent surgery for primary or recurrent pilonidal sinus between 1 January 2016 to 30 June 2019 were included to allow for at least 1-year of follow-up at the time of data collection. MAIN OUTCOME MEASURE: Recurrence rate of PSD and risk factors for recurrence. SAMPLE SIZE AND CHARACTERISTICS: 369 patients: 329 males (89.2%) and 40 (10.8%) females. Median (interquartile range) age was 21 (18-26) years. RESULTS: Of the 369 included patients, recurrence was identified in 84 (22.8%) cases [95% confidence interval (CI) 18.6-27.4], and the mean timing of recurrence was 1.8 (1.6) years after the primary surgery. In a multivariate logistic regression analysis, increased age and post-operative seroma fluid discharge were independent risk factors for recurrence. In contrast, preoperative antibiotic prophylaxis and postoperative hair removal were effective in reducing recurrence. Type of surgery closure had no effect on recurrence, yet primary closure was associated with early onset of recurrence compared to secondary closure ( P =.02). CONCLUSION: Our findings on the factors associated with recurrence of PSD are consistent with many reports in the literature. Reported prevalence estimates vary widely. LIMITATION: Single center, small sample size, retrospective. CONFLICT OF INTEREST: None.

Aim: to identify risk factors for neoplasms recurrence removed by endoscopic mucosal resection (EMR).Patients and methods: the single-center retrospective observational study included 207 patients with 260 benign colon neoplasms. There were 95 (45.9%) males and 112 (54.1%) females. The median age of the patients was 67 (27-80) years. The results obtained were assessed using following criteria: morbidity rate, complication type, hospital stay, tumor site, number of neoplasms in colon, lateral growth, fragmentation rate, technical difficulties (mucosal fold convergence)during surgery, grade of dysplasia, recurrence rate.Results: intraoperative fragmentation of the neoplasms during mucosectomy occurred in 48/260 (18.5%) cases. Postoperative complications within the period of up to 30 days occurred in 13/207 (6.3%) patients. The most frequent 9 (4.2%) postoperative complication arising after mucosectomy was post-polypectomy syndrome. Another 4 (2.0%) patients produced bleeding after the surgery, which required repeated endoscopic procedure. No mortality occurred. The tumor size exceeding 25 mm (Exp (B) = 0.179; 95% CI = 0.05-0.7; p = 0.014), severe dysplasia (Exp (B) = 0.113; 95% CI = 0.03-0.4; p = 0.001) and fold convergence (Exp (B) = 0.2; 95% CI = 0.07-0.7; p = 0.015) are independent risk factors for disease recurrence.Conclusion: mucosectomy is indicated for colon adenomas if its size does not exceed 25 mm and can be removed en bloc.

446 Background: We investigated the impact of postoperative complications on pancreatic cancer survival and recurrence after curative surgery. Methods: This study included 164 patients who underwent curative surgery for pancreatic cancer between 2005 and 2014. The patients were classified into those with postoperative complications (C group) and those without postoperative complications (NC group). The risk factors for overall survival (OS) and recurrence-free survival (RFS) were identified. Results: Postoperative complications were found in 61 of the 164 patients (37.2%). The RFS rate at five years after surgery was 10.6% in the C group patients and was 21.0% in the NC group patients. The RFS tended to be worse in the C group than in the NC group (p=0.1756). The OS rate at five years after surgery was 7.4% in the C group and 22.8% in the NC group, which was significantly different (p=0.0189). The multivariate analysis demonstrated that postoperative complications and lymphatic invasion were significant independent risk factors for the RFS and OS. Conclusions: The development of postoperative complications was a risk factor for a decreased overall survival and for disease recurrence in patients who underwent curative surgery for pancreatic cancer. The surgical procedure, perioperative care and the surgical strategy should be carefully planned to avoid complications.

Abstract Background To evaluate the efficacy and safety of surgical treatment of tuberculosis destroyed lung (TDL), and the influence of chronic pulmonary aspergillosis (CPA) on the outcomes of surgical treatment of TDL. Methods We performed a retrospective analysis of 113 patients with TDL who underwent surgical treatment from January 2005 to December 2019. Among them, 30 of these cases were complicated with CPA. The patients were divided into two groups: TDL group and TDL + CPA group. We analyzed the effectiveness and safety of surgical treatment of TDL, and further compared the effectiveness and safety of surgical treatment of TDL with or withoutthe presence of CPA. Results The TDL + CPA group had a significantly higher age (P=0.003), symptoms of hemoptysis (P=0.000), and a higher proportion of patients with preoperative serum albumin <30 g/L (P=0.014) as compared with TDL group. For all enrolled patients, the incidence of severe postoperative complications was 12.4% (14/113) and the postoperative mortality within 30 days after discharge was 4.4% (5/113). 86.7% (98/113) of the patients recovered and discharged, the incidence of severe postoperative complications in the TDA + CPA group was higher than that of TDL group (23.3% vs 8.4%, P = 0.034), although there was no difference in mortality between the two groups (P = 1.000). A binary logistic regression analysis showed that the independent risk factors for severe postoperative complications were male (OR 25.24, 95% CI 2.31–275.64; P = 0.008) and age ≥ 40 years (OR 10.34, 95% CI 1.56–68.65; P = 0.016). Conclusion Surgical treatment for patients with TDL is effective with an acceptable mortality rate whether or not the disease is complicated with CPA. The independent risk factors identified for severe postoperative complications in patients with TDL were male and ≥ 40 years old. It implies that when treating patients with TDA + CPA, particular attention should be paid to these patients who have these independent risk factors to avoid a poor outcome.

Abstract Background To explore the value of TERT mutations in predicting the early recurrence and prognosis of hepatitis B-related hepatocellular carcinoma (HCC) patients underwent curative hepatectomy.Methods A total of 81 patients with hepatitis B-related HCC were enrolled and all patients underwent curative hepatectomy. Associations were sought between TERT mutations and recurrence rate within 2 years after hepatectomy, time to progress (TTP) and overall survival (OS).Results TERT mutations (HR: 2.985, 95%CI: 1.158-7.692, p=0.024) and Barcelona clinic liver (BCLC) stage B (HR: 3.326, 95%CI: 1.019-10.856, p=0.046) were independent risk factors for recurrence within 2 years after hepatectomy. Patients with a TERT mutation had poor TTP (p=0.003) and OS (p=0.013) than others. TERT mutations (HR: 2.245, 95%CI: 1.185-4.252, p=0.013) and BCLC stage B (HR: 2.132, 95%CI: 1.082-4.198, p=0.029) were independent risk factors for poor TTP after curative hepatectomy. A predictive model based on TERT mutations and BCLC stage had better ability to predict early recurrence after hepatectomy of HCC patients than any single factor (AUC: 0.688 vs. 0.639, 0.688 vs. 0.607, respectively). Patients with both TERT mutations and BCLC stage B had poorer TTP and OS than others (p=0.001, p<0.001, respectively).Conclusion TERT mutations had ability to predict early recurrence and poor prognosis for hepatitis B-related HCC patients underwent curative hepatectomy.
