  • Analysis of clinical features, treatment methods, and prognostic influence factors in patients with malignant peripheral nerve sheath tumor

    Objective To investigate the clinical features, treatment methods, and prognostic influence factors of patients with malignant peripheral nerve sheath tumor (MPNST). MethodsA retrospective analysis was conducted on 96 MPNST patients treated between January 1, 2015 and December 31, 2021. There were 46 males and 50 females, aged between 15 and 87 years (mean, 48.2 years). The tumors were located in the trunk in 50 cases, extremities in 39 cases, and head and neck in 7 cases. The maximum tumor diameter was <5 cm in 49 cases, ≥5 cm in 32 cases, with 15 cases missing data. Tumor depth was deep in 77 cases and superficial in 19 cases. The Fédération Nationale des Centres de Lutte Contre le Cancer (FNCLCC) histological grading was G1 in 9 cases, G2 in 12 cases, and G3 in 34 cases, with 41 cases missing data. There were 37 recurrent MPNST cases, 32 cases with neurofibromatosis type 1 (NF1), and 26 cases in stage Ⅳ. Postoperative adjuvant radiotherapy was administered to 25 patients, perioperative chemotherapy to 45 patients, and anlotinib-targeted therapy to 30 patients. R0 resection was achieved in 73 cases. Patients were divided into groups based on the presence or absence of NF1, and baseline data between the two groups were compared. Kaplan-Meier curves were generated to assess disease-free survival (DFS) and overall survival (OS) based on various factors (age, gender, presence of NF1, recurrent MPNST, stage Ⅳ MPNST, FNCLCC grade, R0 resection, tumor location, tumor size, tumor depth, perioperative chemotherapy, postoperative adjuvant radiotherapy, and anlotinib-targeted therapy), and differences between survival curves were analyzed using the Log-Rank test. Multivariate COX proportional hazards regression was used to identify independent prognostic factors for MPNST. Results Patients with NF1 had a significantly higher proportion of superficial tumors and lower FNCLCC grade compared to those without NF1 (P<0.05); no significant difference was found for other variables (P<0.05). Kaplan-Meier analysis showed that recurrent MPNST, stage Ⅳ MPNST, FNCLCC grade, R0 resection, perioperative chemotherapy, and anlotinib-targeted therapy were factors influencing 1-year DFS (P<0.05), while stage Ⅳ MPNST, FNCLCC grade, and perioperative chemotherapy were factors affecting 3-year OS (P<0.05). Multivariate COX proportional hazards regression analysis revealed that recurrent MPNST and high-grade FNCLCC (G3) were independent prognostic factors for 1-year DFS (P<0.05), while stage Ⅳ MPNST, superficial tumor depth, age over 60 years, postoperative adjuvant radiotherapy, and anlotinib-targeted therapy were independent prognostic factors for 3-year OS (P<0.05). Conclusion MPNST patients with NF1 tend to have more superficial tumors and lower FNCLCC grades. FNCLCC grade, R0 resection, and adjuvant therapies, including radiotherapy and anlotinib-targeted therapy, are closely associated with MPNST prognosis. Complete surgical resection should be prioritized in clinical management, along with adjuvant treatments such as radiotherapy and targeted therapy of anlotinib to improve patient outcomes.

  • Efficacy and Safety of Intraoperative Mesenchymal Chemotherapy with 5-Fluorouracil Release Formulation in Radical Gastrectomy of Advanced Gastric Cancer

    Objective To evaluate the efficacy and safety of intraoperative mesenchymal chemotherapy with 5-FU implants in radical gastrectomy of advanced gastric cancer. Methods From January 2008 to September 2009, 102 patients with historically proven advanced gastric cancer were enrolled in our department and were allocated to undergo either radical gastrectomy and intraoperative mesenchymal chemotherapy with 5-FU implants 800 mg(treatment group, n=51), or radical gastrectomy alone (control group, n=51). The postoperative complications and recurrence rate between two groups were compared. Results There were no significant differences on the volume of abdominal cavity drainage, count of white blood cells, albumin level, and gastrointestinal adverse events between the two groups (P>0.05). After a median follow-up of 28 months, the local recurrence rate was lower among patients in treatment group than that in control group (16.3% vs. 39.1%, P<0.05), the survival rate of 3-year was higher in treatment group than that in control group (85.8% vs. 67.3%, P<0.05). Conclusions Compared with the control group, there are no significant adverse reactions on patients with advanced gastric cancer who were implanted fluorouraci1 implants during operation, which can reduce local recurrence rates and improve the survival rates.

  • Clinical and Pathologic Factors Analysis of Postoperative Local Recurrence of Rectal Cancer

    Objective To discuss the clinicopathologic risk factors related to local recurrence of rectal cancer after radical surgery. Methods The complete clinicopathologic data of 368 patients with rectal cancer from January 2004 to April 2011 in this hospital were retrospectively analyzed by univariate and multivariate analysis methods. Results There were 73 cases suffered from local recurrence and accounted for 19.84% (73/368) of rectal cancer during the same period. Univariate analysis results showed that gender, tumor from anal margin, tumor circumference, TNM staging, histology type, vessel infiltration, tumor perforation, stomal leak, and chemoradiotherapy were associated with postoperative recurrence (P<0.05). Multivariate analysis results showed that tumor from anal margin, tumor circumference, TNM staging, histology type, vessel infiltration, tumor perforation, and chemoradiotherapy were prognostic factor for local recurrence of rectal cancer (P<0.05). Conclusions There are many factors related to postoperative local recurrence, but the most dangerous factor is vessel infiltration.

  • Progress of breast conserving therapy in patients with multifocal/multicentric breast cancer

    ObjectiveTo discuss the feasibility and security of breast conserving surgery (BCS) in patients with multifocal/multicentric breast cancer (MMBC).MethodThe clinical trials about BCS in patients with MMBC at home and abroad in recent years were searched and reviewed.ResultsThe results of most retrospective clinical trials showed that BCS in patients with MMBC could achieve similar or at least as good results as mastectomy. However, for there were some inevitable bias in retrospective studies, the conclusion should be analyzed modestly. Two prospective multicenter randomized controlled trials, the MIAMI UK trial and the ACOSOG Z11102 trial, were still ongoing, of which results were expected to confirm these conclusions further. ConclusionsUnder the premise of mastering the indications, BCS would be a reasonable option for MMBC when incisal margin is negative and cosmetic result is satisfactory. In addition, the lack of standard classification and definition for multifocality and multicentricity increases the difficulty of the research, and the distance of the cancer foci and the ratio of tumor to breast volume in patients with MMBC might be the key factors affecting the efficacy of BCS. Therefore, more rational-designed prospective studies and accurate subgroup analysis are expected to provide impelling evidence for application of BCS in patients with MMBC.

  • Reoperation for Local Recurrence of Rectal Cancer(Analysis of 56 Cases)

    Objective To approach the surgical therapeutic efficacy of local recurrence of rectal cancer. Methods Fifty-six patients with local recurrence of rectal cancer suffered from reoperation from January 2003 to January2011 in this hospital were collected. Chi-square test was performed to analyze the complete excision rates of reoperation for different recurrent time after radical resection and different surgical procedures after primary radical resection of rectalcancer. The method of log-rank test was used for survival analysis of the Miles and Dixon procedure. Results ①The opera-tion time and intraoperative bleeding of reoperation for local recurrence of rectal cancer were more than those of the primary radical resection of rectal cancer (P<0.05). ②The complete resection rate of the local recurrence of rectal cancer in 5 years after primary radical resection of rectal cancer was higher than that of the local recurrence of rectal cancer within 2 years after primary radical resection of rectal cancer, and the difference was statistically significant (P<0.01). ③The complete resection rate of the local recurrence of rectal cancer of the technique of Dixon in the primary radical resection of rectal cancer was higher than that of Miles, and the difference was statistically significant (P<0.05). ④The median survival time and 2-year survival rate and 5-year survival rate of the technique of Dixon in the reoperation were longer or higher than those of Miles, and the differences were statistically significant (P<0.05). Conclusions Surgical procedure and postoperative recurrence time after primary operation can both influence complete excision rate of reoperation for local recurrence of rectal cancer. And reoperation for local recurrence of rectal cancer can prolong the survival time.
