Abstract Background As segmentectomy had become commonly used for Non-Small Cell Lung Cancer (NSCLC) treatment, which had the advantages of radical operation, however, it remains controversial owing to procedural complexity and risk of increased complications compared with wedge resection. We evaluated operative and postoperative outcomes of simple segmentectomy compared to wedge resection in ground-glass opacity (GGO) diameter between 2 cm and 3 cm NSCLC. Methods We retrospectively reviewed 1600 clinical GGO diameter between 2 cm and 3 cm NSCLC patients who received simple segmentectomy and wedge resection between Jan 2011 and Jan 2015. Participants were matched 1:1 on their propensity score for two groups. Clinic-pathologic, operative, and postoperative results of two groups were compared. Results After using propensity score methods to create a matched cohort of participants with simple segmentectomy group similar to that wedge resection, there were no significant differences detected in tumor size, margin distance, histology, age, sex, preoperative comorbidities and preoperative pulmonary function. Overall complications in simple segmentectomy group were more than wedge resection group (21% vs 3%, p = 0.03). Median operative time (110.6 vs. 71.2 min; p = 0.01) and prolonged air leakage (12% vs. 3%; p = 0.02) was significantly longer in the simple segmentectomy group. There was no difference in recurrence free survival (RFS) and overall survival (OS) of 5-years between simple segmentectomy group and wedge resection group. Postoperative pulmonary function in simple segmentectomy group recovered more slowly than wedge resection group. Conclusion Wedge resection may have comparable efficacy as simple segmentectomy for GGO diameter between 2 cm and 3 cm NSCLC, but lead to less complications, less surgical procedure and faster recovery of pulmonary function.

Objective: To evaluate the effectiveness of radical resection compared with non-radical resection for vaginal or cervical melanoma.Methods: We retrospectively analysed the clinical data of post-operative patients with primary lower genital tract melanoma hospitalised at Peking University Cancer Hospital between Jan 2014 and Dec 2020. The study endpoints were recurrence-free survival (RFS) and overall survival (OS). Kaplan–Meier method-plotted survival curves and univariate and multivariate Cox proportional hazards regression models were used to identify the factors associated with RFS and OS, and to calculate hazard ratios (HRs) and associated 95% confidence intervals (95% CIs).Results: A total of 80 patients were included. Thirty-one patients had received non-radical resection, and 49 patients had received radical resection. The median patient age was 55.5 (IQR 45.3–60.0) years. Sixty-two (77.5%) patients had vaginal melanoma. Sixty-four patients (80.0%) had received post-operative adjuvant therapy. The median follow-up time was 36.0 months (95% CI 10.1–62.1 months). Sixty-four patients developed recurrence, and 44 patients died. The median RFS (mRFS) was 6.0 months (95% CI 3.4–8.6 m), and the RFS for the radical resection group was longer than that for the non-radical resection group (9.5 vs. 5.3 m), with no significant difference (P > 0.05). The median OS (mOS) was 25.9 months (95% CI 14.4–37.4 m). The mOS was 24.6 months (95% CI 10.3–38.9 m) and 25.9 months (95% CI 10.9–40.9 m) in the non-radical resection group and the radical resection group, respectively. Multivariate Cox regression analysis showed that surgical approach, infiltration depth of the tumour, lymph node metastasis, and post-operative adjuvant therapy were independent risk factors for RFS and that post-operative adjuvant therapy was an independent risk factor for OS.Conclusion: By performing multivariate analysis, which corrected for potential confounding factors, we identified surgical procedures that were associated with RFS, and we found that RFS and OS in patients with vaginal melanoma and cervical melanoma benefitted from post-operative adjuvant therapy.

Abstract Background The classification and treatment strategy of atypical central neurocytomas (CNs) are still controversial largely, this study aimed to explore the optical treatment strategy and characteristics in transcriptomic profile. Methods This study retrospectively analyzed data from Sixty-one patients with CNs who underwent surgery in single institution. Whole-transcriptome analysis was used to investigate the differences between typical and atypical CNs. Results The five-year OS (P= 0.015) and PFS rates (P= 0.000002) were significantly higher in the complete resection group than in the incomplete resection group. Postoperative radiotherapy did not affect OS (P=0.255) or PFS (P=0.398) in the complete resection group. The five-year PFS rate (P=0.000038) among patients in the complete resection group who did not receive radiotherapy was significantly longer than that among patients in the incomplete resection group who received radiotherapy. The extent of surgical resection and operative approaches were irrelevant to perioperative complications and dsyfunctions at the last follow-up. Compared with caudate control, some of differentially expressed genes may involve cancer. Finally, the overexpression of ten genes (AMOTL1, PIK3R3, TGFBR1, SMO, COL4A6, MGP, SOX4, IGF2, Slit1 and CKS2) in atypical CNs may be associated with malignancy in atypical CNs. Conclusion Complete resection is relatively the best therapeutic modality for atypical CNs, radiotherapy is not necessary for patients after complete resection of the tumor. Although the previous definition of atypical CNs may not have significant prognostic value, the overexpression of ten genes may be involved in malignant behaviors and potential candidate hallmarks for differentiating the atypical CNs. Although the number of cases was relatively small, the findings could be helpful and instructive in the clinical treatment of this disease.

OBJECTIVE Speech arrest is a common but crucial negative motor response (NMR) recorded during intraoperative brain mapping. However, recent studies have reported nonspeech-specific NMR sites in the ventral precentral gyrus (vPrCG), where stimulation halts both speech and ongoing hand movement. The aim of this study was to investigate the spatial relationship between speech-specific NMR sites and nonspeech-specific NMR sites in the lateral frontal cortex. METHODS In this prospective cohort study, an intraoperative mapping strategy was designed to identify positive motor response (PMR) sites and NMR sites in 33 consecutive patients undergoing awake craniotomy for the treatment of left-sided gliomas. Patients were asked to count, flex their hands, and simultaneously perform these two tasks to map NMRs. Each site was plotted onto a standard atlas and further analyzed. The speech and hand motor arrest sites in the supplementary motor area of 2 patients were resected. The 1- and 3-month postoperative language and motor functions of all patients were assessed. RESULTS A total of 91 PMR sites and 72 NMR sites were identified. NMR and PMR sites were anteroinferiorly and posterosuperiorly distributed in the precentral gyrus, respectively. Three distinct NMR sites were identified: 24 pure speech arrest (speech-specific NMR) sites (33.33%), 7 pure hand motor arrest sites (9.72%), and 41 speech and hand motor arrest (nonspeech-specific NMR) sites (56.94%). Nonspeech-specific NMR sites and speech-specific NMR sites were dorsoventrally distributed in the vPrCG. For language function, 1 of 2 patients in the NMA resection group had language dysfunction at the 1-month follow-up but had recovered by the 3-month follow-up. All patients in the NMA resection group had fine motor dysfunction at the 1- and 3-month follow-ups. CONCLUSIONS The study results demonstrated a functional segmentation of speech-related NMRs in the lateral frontal cortex and that most of the stimulation-induced speech arrest sites are not specific to speech. A better understanding of the spatial distribution of speech-related NMR sites will be helpful in surgical planning and intraoperative mapping and provide in-depth insight into the motor control of speech production.

Abstract BackgroundThe efficacy of RFA in the treatment of HCC with severe fibrosis is still unclear. The objective of this study is to compare the efficacy of RFA with liver resection in the treatment of HCC within Milan criteria.MethodsThe data used in the study were from the SEER database. Patients with HCC within Milan criteria were included in the study. A total of 1432 patients were included in the study; among them, 1038 patients received RFA, and 394 patients received liver resection. Propensity score matching (PSM) was used to reduce selection bias.ResultsBefore PSM, the median overall survival (mOS) and median cancer-specific survival (mCSS) in the resection group were longer than the mOS and mCSS in the RFA group. However, the8re were no statistically significant differences in mOS or mCSS between the two groups (both P>0.05). After PSM, similar results were presented, and the mOS and mCSS in the resection group were similar to those in the RFA group (both P>0.05). The multivariable Cox regression analysis showed that RFA did not increase the all-cause mortality risk and cancer-specific mortality risk compared with resection before PSM. In the competing risk analysis, after excluding the potential factors that might influence the outcomes, RFA still did not increase the mortality risk compared with resection before PSM and after PSM. In the subgroup analysis. The efficacy of RFA is comparable to that of resection in patients with tumor sizes no more than 3 cm before PSM and after PSM.ConclusionThe efficacy of RFA is similar to that of resection in the treatment of early HCC patients with severe fibrosis, especially in patients with tumor sizes no more than 3 cm.

It remains controversial whether surgical resection, compared to radiofrequency ablation (RFA), improves overall survival (OS) in patients with early hepatocellular carcinoma (HCC). This study aimed to compare OS after RFA with that after resection for HCC. This retrospective study included patients who underwent RFA or surgical resection as initial treatment for hepatitis B virus (HBV)-related HCC at a very early or early stage. A total of 761 patients (RFA, n = 194; resection, n = 567) from Seoul National University Hospital (Seoul, South Korea) and 1277 patients (RFA, n = 352; resection, n = 925) from the Korean Primary Liver Cancer Registry were included in the hospital and nationwide cohorts, respectively. Primary and secondary endpoints were OS and recurrence-free survival (RFS), respectively. Additional analysis was performed when the history of the antiviral treatment and the type of prescribed nucleos(t)ide analogue were confirmed. The rate of complications was compared between the two treatment groups in the hospital cohort. Baseline characteristics were balanced, using inverse probability of treatment weighting (IPTW). In the hospital cohort, the RFA group had a smaller mean tumor size (1.7 vs. 3.9 cm) but a higher proportion of cirrhotic patients than the resection group (85.6% vs. 63.1%) (both p < 0.01). During 81.0 (interquartile range, 62.3–107.1) months of follow-up, there was no difference in OS (adjusted hazard ratio (aHR) = 0.870, 95% confidence interval (CI) = 0.400–1.897, p = 0.73) and RFA was associated with shorter RFS (aHR = 1.562, 95% CI = 1.099–2.219, p = 0.01) after employing IPTW. Antiviral treatment was independently associated with longer OS (aHR = 0.444, 95% CI = 0.251–0.786, p = 0.01) as well as RFS (aHR = 0.544, 95% CI = 0.391–0.757, p < 0.01) in the hospital cohort. In the nationwide cohort, there was no difference in OS (aHR = 0.981, 95% CI = 0.661–1.456, p = 0.92) between the two treatment groups when adjusted for antiviral treatment, which was a negative independent risk factor for mortality (aHR = 0.655, 95% CI = 0.451–0.952, p = 0.03) after IPTW. Among patients treated with tenofovir (n = 96) or entecavir (n = 184) in the hospital cohort, there was no difference in either OS (aHR = 0.522, 95% CI = 0.058–4.724, p = 0.56) or RFS (aHR = 1.116, 95% CI = 0.738–1.688, p = 0.60). The overall incidence of complications was higher in the resection group (26.3%) than in the RFA group (13.9%) (p < 0.01). RFA may provide comparable OS to resection in the treatment of very early or early HCC with a lower rate of complications, although RFS is marginally shorter than in the resection group after adjusting for antiviral treatment. Regardless of the type of NA, antiviral treatment in patients with HBV-related HCC is strongly associated with both OS and RFS.

Recent studies have obtained inadequate data on the association between nutritional status, body composition, clinical parameters and tumor stage in patients withpancreatic and periampullary tumors. The purpose of this study was to assess the relationship between nutritional status (NS), body composition (BC) and selected clinical parameters in patients with pancreatic and periampullary cancer, as well as describe the differences between resection and non-resection groups. This is a prospective study of 76 patients with pancreatic and periampullary tumors. We evaluated NS, BMI, body mass loss (BML) and albumin, total protein, CRP, CEA, CA19-9, lipase, amylase, tumor stage, and BC using bioelectrical impedance (BIA). All subjects were divided into resection (n = 59) and non-resection (n = 17) groups. The non-resection group had a worse NS, as well as increased amylase and WBC, compared to the resection. The selected parameters of BC corresponded to BML albumin, TP, NS, age, BMI, Karnofsky, RBC, HCT and HGB. No associations were found between BC with tumor size, CRP, CA19-9, and CEA. We recorded the relationship between metastasis and NRS, as well as tumor size with SGA. The percentage of BML was positively correlated with age and CRP but negatively correlated with RBC, HGB, HCT and anthropometric measurements. We found many statistical correlations with NS and selected parameters, as well as differences between the resection and non-resection group. The detection of early prognostic factors of nutritional impairments would improve the quality of life and reduce the rate of postoperative complications.

Abstract Surgical resection is the first choice for the treatment of small intestinal gastrointestinal stromal tumors (GISTs), but the best surgical method for small intestinal stromal tumors remains undefined. It is not clear whether there is a difference in the long-term survival of small intestinal GISTs between radical surgery and non-radical surgery. We included 877 patients with small intestinal stromal tumors who underwent surgery between 2010 and 2015 from the SEER database. They were divided into the radical resection group and the non-radical resection group. To minimized the selection bias and mixed bias in the comparison, propensity score matching (PSM) and multivariate regression analysis were carried out. In the entire cohort, 120 patients underwent radical surgery and 757 patients received non-radical resection. The 1, 3, and 5-year OS rates were 95.7%, 80.2%, and 69.6% in the radical resection group versus 94.3%, 86.8%, and 77.2% in the non-radical resection group, respectively. (p=0.069) Meanwhile, radical resection had the similar CSS rates of 1, 3 and 5-year compared with non-radical surgery. (1-year CSS rate: 97.4% vs. 98.0%, 3-year CSS rate: 86.1% vs. 93.2%, 5-year CSS rate: 81.6% vs. 88.3%; p =0.056) Besides, after adjusting for other clinical factors and PSM, the long-term OS and CSS did not significantly differ between radical surgery and non-radical surgery. Our study preliminarily found that for small intestinal GISTs, there was no significant difference in long-term survival between radical surgery and non-radical surgery.

Abstract Background Laparoscopic liver resection (LLR) has been progressively developed along the past two decades. Liver surgery was one of the last frontiers reached by minimally invasive surgery. Surgical technique and equipment evolved to overcome technical limitations, making laparoscopic liver resections (LLR) safe and feasible. Surgeons developed skills in a stepwise approach, beginning with low complexity operations for benign diseases and reaching high-complexity surgeries for malignant cases and living donor organ harvesting. Objective s: The aim of the study is to compare short term results of laparoscopic versus open hepatectomy regarding to intra operative details and post-operative management and complications for achieving a safe hepatic resection for treatment of HCC in cirrhotic patients. Patients and Methods In this prospective study, a comparison between laparoscopic resection and open resection was done to compare short-term results between laparoscopic and open liver resection. This study was conducted on 30 patients with hepatocellular carcinoma. 15 patients (50%) were treated by laparoscopic liver resection (Group A) while the other 15 patients (50%) were treated by open liver resection (Group B). Results Regarding the demographic data, the presence of past history of medical condition and the preoperative laboratory results, no statistical significance was found. The mean operative time has statistically significant difference between the 2 groups, with decreased operative time in the laparoscopic group (P &lt; 0.001). The mean blood loss has no statistically significant difference relations between the 2 groups, (P = 0.866) with conversion rate of (13.3%) happened in two cases. Conclusion Laparoscopic liver resection is a safe and feasible treatment option for HCC in cirrhotic patient needing minor resection at laparoscopic segments (II, III, IVa,V,VI). Laparoscopic liver resection for HCC has superior short- term and comparable oncological outcomes to open liver resection. LLR should be performed for carefully selected patients and by an expert surgical team.

Abstract Objectives: To evaluate the feasibility and advantages of wedge resection plus transverse suture applied to loop ileostomy closure by analyzing the surgical data and the incidence of postoperative complications of patients undergoing this procedure.Methods: We performed a retrospective analysis of the hospitalization data of patients who underwent ileostomy closure surgery and met the research standards from January 2017 to April 2021 in the Guangxi Medical University Cancer Hospital; all surgeries were performed by the same surgeon. The perioperative data were statistically analyzed by grouping.Results: In total, 65 patients were enrolled in this study, with 12 in the wedge resection group, 35 in the stapler group, and 18 in the hand suture group. There was no significant difference in operation time between the wedge resection group and stapler group (P > 0.05), but both groups had shorter operation time than that in the hand suture group (P< 0.05). The postoperative exhaustion time of wedge resection group was earlier than that of the others, and cost of surgical consumables in the wedge resection group was significantly lower than that in the stapler group, all with statistically significant differences (P< 0.05). By contrast, there was no statistically significant difference in postoperative complication incidences among the three groups.Conclusions: The wedge resection plus transverse suture is safe and easy for closure of loop ileostomy, and the intestinal motility recovers rapidly postoperatively. It has less surgical consumables, and is particularly suitable for the currently implemented Diagnosis-Related Groups payment method.
