Objective To explore the feasibility and short-term effectiveness of the modified radical resection and reconstruction in the treatment of malignant proximal humerus tumor. Methods The relevant anatomic data from 30 normal adult shoulder joint MRI were measured to analyze the feasibility of modified radical resection and reconstruction surgery in the treatment of malignant proximal humerus tumor. Five patients with malignant proximal humerus tumor were treated by using the modified radical resection and reconstruction surgery between March 2012 and January 2016. There were 1 male and 4 females, aged from 9 to 69 years (median, 46 years). There were 4 cases of osteosarcoma (Enneking IIA in 2 cases and Enneking IIB in 2 cases) and 1 case of metastatic carcinoma (moderately differentiated adenocarcinoma). The disease duration was 7 to 12 months (mean, 9 months). Recurrence of tumor was observed after operation, and the shoulder function was assessed according to Enneking skeletal muscle tumor function scoring system. Results Radiographic results showed that modified radical resection and reconstruction surgery was feasible, which was in allowable range of the maximum longitudinal diameter ( < 29.8 mm) and depth ( < 4 mm). The operation was successfully completed in all 5 cases, and pathological examination suggested that purposes of radical resection had achieved. All patients were followed up 3 to 49 months (mean, 15.6 months). One patient had local recurrence at 12 months after operation, and a shoulder joint amputation was performed; the other 4 patients had good prosthesis survival. At last follow-up, the function of the shoulder joint was obviously recovered when compared with preoperative function; Enneking's skeletal muscle tumor function score was 25.8 points (range, 24 to 27 points). Conclusion Modified radical resection and reconstruction surgery is feasible for the treatment of proximal humerus tumor, and it can maintain a good early shoulder function.
Objective To summarize the application and progress of common autologous organ transplantation (AOT) techniques. Method A literature review and summary of previous and recent studies on common AOT was performed, including autologous liver transplantation, autologous kidney transplantation and intestinal autotransplantation techniques. Results AOT solved the issues of bleeding that cannot be controlled by in vivo resection of lesions, difficulties in vascular reconstruction, and the inability to radically resect lesions, and extended the indications for treatment of partially diseased conditions. Conclusions The AOT technique has an ameliorating effect on the tight donor situation in China, providing more potential donors. And the application of the AOT technique effectively avoids the usage of postoperative immunosuppressive drugs and the progression of lesions due to waiting for allogeneic organ transplantation. However, the clinical benefit in malignant tumors remains to be further investigated.
Objective To evaluate the effectiveness and advantages of the wide local excision for Paget’s disease involing the penis and scrotum by comparing with the radical excision. Methods A retrospective analysis was made on the clinical data of 41 patients with Paget’s disease involving penis and scrotum who met the inclusion criteria between November 2010 and August 2015. Among them, 14 patients received wide local excision (group A), and 27 patients received radical excision (group B). No significant difference was found in age, course of disease, and lesion site between two groups (P>0.05). The recurrence rate, operative time, times of intraoperative frozen section pathology, hospitalization time, grade of wound healing, appearance and functions satisfaction were recorded and compared between two groups. Results The operative time and hospitalization time in group A were significantly shorter than those in group B (P<0.05); the times of intraoperative frozen section pathology in group A were significantly less than that in group B (P<0.05). All patients were followed up 13 to 67 months (mean, 35.5 months) in group A and 11 to 70 months (mean, 38.8 months) in group B. Grades A, B, and C wound healing was obtained in 11 cases, 2 cases, and 1 case of group A and in 12 cases, 7 cases, and 8 cases of group B respectively, showing significant difference between two groups (Z=–2.102, P=0.036). The 5-year recurrence rate was 28.6% (4/14) in group A and 22.2% (6/27) in group B, showing no significant difference (χ2=0.202, P=0.654). The score of satisfaction in appearance and functions in group A was significantly higher than that in group B (t=–2.810, P=0.008). Conclusion Paget’s disease involving penis and scrotum has a slow disease progression and good prognosis. Wide local excision can relieve symptoms effectively and obviously decrease perioperative risk in elderly patients, with no significant increase of the recurrence rate.
ObjectiveTo explore the influencing factors of textbook outcomes (TO) after radical resection for hepatic alveolar echinococcosis (HAE). MethodsClinical data from 427 patients diagnosed with HAE at the Ganzi Branch of West China Hospital, Sichuan University, between 2015 and 2022, were retrospectively collected. The least absolute shrinkage and selection operator regression (LASSO) was first used to screen potential influencing factors for achieving TO (predictive model A). Univariate and multivariate logistic regression analysis were then used to explore the influencing factors of TO (predictive model B). A Nomogram was further constructed and validated. ResultsA total of 427 patients who successfully underwent radical liver resection were included, of which 174 patients (40.7%) achieved TO. Compared to the non-TO group, patients in the TO group had higher proportions of WHO PNM stage of P 1+2 [62.6% (109/174) vs 42.3% (140/253)], N0 [77.0% (134/174) vs 63.6% (161/253)], lesion diameter≤10 cm [77.0% (134/174) vs 64.8% (164/253)], albumin-bilirubin index (ALBI) ≤–2.6 [70.1% (122/174) vs 59.3% (150/253)], and minor liver resection [71.8% (125/174) vs 50.2% (127/253)], higher prealbumin (181 mg/L vs 169 mg/L) and albumin (39 g/L vs 38 g/L) levels, shorter postoperative hospital stay (15 d vs 19 d), and lower hospitalization costs (51 727 RMB vs 62 715 RMB), P<0.05. LASSO regression analysis indicated that P stage, lesion diameter, ALBI, and liver resection method were potential influencing factors for achieving TO after HAE surgery (model A), P<0.05. The TO rate for P 1+2 stage was higher than that of P 3+4 stage, the TO rate for lesion diameter ≤ 10 cm was higher than that of lesion diameter >10 cm, the TO rate for ALBI ≤–2.6 was higher than that of ALBI >–2.6, and the TO rate for minor liver resection was higher than of major liver resection. Multivariate logistic regression analysis showed that P stage (OR=1.800, P=0.025) and liver resection method (OR=1.974, P<0.001) were influencing factors for achieving TO (model B). The TO rates for P1+2 stage and minor liver resection were higher. Predictive model A demonstrated higher accuracy and stability compared to predictive model B (AUC: 0.754 vs 0.712, C-index: 0.756 vs 0.707). ConclusionsAmong patients undergoing radical resection for HAE, less than half achieved TO. Striving to achieve TO can significantly shorten the length of hospital stay and effectively reduce medical costs. The TO predictive model based on P stage, lesion diameter, ALBI, and liver resection method is superior to the model based solely on P stage and liver resection method.
ObjectiveTo evaluate feasibility of laparoscopic radical resection and re-resection for suspicious and incidental gallbladder cancer.MethodsWe searched PubMed and other databases, reviewed relevant literatures and summarized from aspects like whether efficacy comparable to laparotomy and enough lymph node dissection could be achieved through laparoscopy, timing of reoperation for incidental gallbladder cancer.ResultsLaparoscopic radical resection and re-resection were theoretically and technically feasible, but its efficacy and timing of re-resection were controversial, and its long-term efficacy needed further discussions in multi-center and large-scale cohort studies.ConclusionsLaparoscopy shows prospects of resection and re-resection for suspicious and incidental gallbladder cancer. Tentative explorations could be done in properly selected patients by well-experience medical centers and to achieve efficacy comparable to laparotomy is the fundamental principle.
Objective To study the effect of HBeAg on recurrence and survival after radical resection of small (≤3 cm) hepatocellular carcinoma (HCC). Methods Two hundreds and twenty-three HCC patients undergone radical resection from 1999 to 2000 were divided into two groups according to serum HBeAg status， HBeAg positive group (n=73) and HBeAg negative group (n=150). The patients’ factors, operative factors and tumorous facors were studied retrospectively between the two groups. And risk factors of overall survival (OS) and disease-free survival (DFS) were analyzed. Results There were no significant differences in operative and tumorous factors between the two groups, but the HBeAg positive group were younger with more severe cirrhosis (P=0.004, P=0.008). The OS and DFS were significantly different between the HBeAg positive group and HBeAg negative group. The 1-, 3- and 5-year OS were 91.5%, 76.8%, 60.1% and 95.2%, 85.3%, 73.2%, respectively (P=0.053)； and the 1-, 3- and 5-year DFS were 73.3%, 53.7%, 40.3% and 86.6%, 65.5%, 54.5%, respectively (P=0.002). Multivariate analysis revealed that age ＞50 years, HBeAg positive and macronodular cirrhosis were significantly related to OS, and HBeAg positive, multiple tumor nodulars were significantly related to DFS. Positive serum HBeAg status was an independent risk factor for both OS and DFS. Conclusion Positive serum HBeAg is closely related to early recurrence and survival after radical resection of patients with small HCC.
Objective To compare the clinical efficacy and safety of different surgical methods in the treatment of early-stage gallbladder carcinoma (GBC). Methods The clinical data of 43 patients with early-stage GBC who received treatment in Peking University People’s Hospital from Jan. 2010 to Dec. 2016 were retrospectively analyzed. According to the surgical methods, the patients were divided into laparoscopic cholecystectomy (LC)+lymph node dissection (LND)+radiofrequency ablation (RA) group, open cholecystectomy (OC)+LND+RA group, and OC+LND+liver resection (LA) group. Operation duration, intraoperative blood loss, postoperative hospital stay, surgical complications, and long-term survival were compared among the 3 groups. Results All the 43 patients performed successful surgery without perioperative death. ① Operation duration and postoperative hospital stay. The differences of operation duration and postoperative hospital stay among the 3 groups were statistically significant (P<0.05). Compared with the LC+LND+RA group, operation duration and postoperative hospital stay of the OC+LND+RA group and the OC+LND+LR group were longer (P<0.017), but there was no statistically significant difference between the OC+LND+RA group and the OC+LND+LR group (P>0.017). ② Intraoperative blood loss. The difference of intraoperative blood loss among the 3 groups was statistically significant (P<0.001). Compared with the OC+LND+LR group, the intraoperative blood loss was lower in the LC+LND+RA group and the OC+LND+RA group (P<0.017), but there was no significant difference between the LC+LND+RA group and the OC+LND+RA group (P=0.172). ③ Postoperative complications. There was no significant difference in the incidence of postoperative complications among the 3 groups (P=0.326). ④ Long-term survival. There was no significant difference in survival curves among the 3 groups (P=0.057). Conclusions The method of cholecystectomy combined with LND and RA of gallbladder bed can achieve the radical effect on early-stage GBC (Tis–T2). Laparoscopic surgery, in particular, has shorter operation duration and faster recovery.
ObjectiveTo evaluate the influence of clinical, pathological and treatment factors on the prognosis of thymic carcinoma patient accepted surgical treatment.MethodsRetrospective analysis was performed on 38 patients with thymic carcinoma undergoing surgical treatment between January 2008 and December 2017. The association between the prognostic factors including age, sex, thymectomy, radical resection, pathological type, TNM stage, Masaoka-Koga stage, tumor size, and survival was assessed using the Kaplan-Meier method.ResultsThe 5-year overall survival rate of our cohort was 51.9%. Kaplan-Meier univariate survival analysis showed that radical resection (P=0.003), TNM stage (P=0.038), Masaoka-Koga stage (P=0.033), and tumor size (P=0.030) were related to the prognosis of patients with thymic carcinoma. Radical resection was also validated as an independent prognostic factor in multivariate Cox analysis (P=0.009, hazard ratio 2.31, 95%CI 1.23-4.33).ConclusionRadical surgical treatment could improve the prognosis of patients with resectable thymic carcinoma.
