Rectal cancer is one of the most malignant tumors in gastrointestinal tract, while low rectal cancer with locally advanced stage is the most common type in China. The concept of neo-adjuvant therapy has challenged the traditional treatment strategy for rectal cancer, and has showed encouraging effects in local relapse control, radical resection and sphincter preservation. However, some important issues still remain controversial, including course and dose of radiotherapy, choice of chemotherapy regimen, long-term benefits. This article aims to review and discuss related issues of neo-adjuvant therapy.

2.Application of biotherapy in recurrent or metastatic gastric cancer.
Chinese Journal of Gastrointestinal Surgery 2011;14(8):569-572
Post-operative recurrence and metastasis remain the leading causes of death for patients with gastric cancer. The major determinants of recurrence and metastasis are the biological characteristics of cancer cells and the immunological status of the patients. In recent years, due to the target-specificity, biotherapy has yielded efficacious responses in diverse clinical applications for cancer treatment, partially for the treatment of recurrence and metastasis of gastric cancer. However, because of the high diversities in clinical manifestations, patients' condition, and tumor's characteristics, there is no ideal strategy of biotherapy established for the prevention and treatment of recurrence and metastasis in gastric cancer. Therefore, a lot of work need to be done in basic research and clinical trial to make the biotherapy effective in treatment of gastric cancer recurrence.

4.Advances and challenges in neoadjuvant treatment for colorectal cancer liver metastasis.
Chinese Journal of Gastrointestinal Surgery 2021;24(10):919-924
Liver metastasis is the leading cause of death in patients with colorectal cancer. Since surgical resection alone has a high postoperative recurrence rate, neoadjuvant therapy as an important means is widely applied in order to reduce recurrence and improve survival. Progress has been achieved in many aspects of neoadjuvant therapy in colorectal cancer liver metastasis, such as eligible patients selection, optimal regimens and courses of chemotherapy. However, controversies still remain regarding the standards of resectability of lesions and the application of targeted drugs. Individualized treatments could be developed based on multidisciplinary teamwork to achieve the goal of 'resources integration and treatment stratification'.

Objective: To propose a new staging system for presacral recurrence of rectal cancer and explore the factors influencing radical resection of such recurrences based on this staging system. Methods: In this retrospective observational study, clinical data of 51 patients with presacral recurrence of rectal cancer who had undergone surgical treatment in the Department of Gastrointestinal Surgery, Peking University People's Hospital between January 2008 and September 2022 were collected. Inclusion criteria were as follows: (1) primary rectal cancer without distant metastasis that had been radically resected; (2) pre-sacral recurrence of rectal cancer confirmed by multi-disciplinary team assessment based on CT, MRI, positron emission tomography, physical examination, surgical exploration, and pathological examination of biopsy tissue in some cases; and (3) complete inpatient, outpatient and follow-up data. The patients were allocated to radical resection and non-radical resection groups according to postoperative pathological findings. The study included: (1) classification of pre-sacral recurrence of rectal cancer according to its anatomical characteristics as follows: Type I: no involvement of the sacrum; Type II: involvement of the low sacrum, but no other sites; Type III: involvement of the high sacrum, but no other sites; and Type IV: involvement of the sacrum and other sites. (2) Assessment of postoperative presacral recurrence, overall survival from surgery to recurrence, and duration of disease-free survival. (3) Analysis of factors affecting radical resection of pre-sacral recurrence of rectal cancer. Non-normally distributed measures are expressed as median (range). The Mann-Whitney U test was used for comparison between groups. Results: The median follow-up was 25 (2-96) months with a 100% follow-up rate. The rate of metachronic distant metastasis was significantly lower in the radical resection than in the non-radical resection group (24.1% [7/29] vs. 54.5% [12/22], χ2=8.333, P=0.026). Postoperative disease-free survival was longer in the radical resection group (32.7 months [3.0-63.0] vs. 16.1 [1.0-41.0], Z=8.907, P=0.005). Overall survival was longer in the radical resection group (39.2 [3.0-66.0] months vs. 28.1 [1.0-52.0] months, Z=1.042, P=0.354). According to univariate analysis, age, sex, distance between the tumor and anal verge, primary tumor pT stage, and primary tumor grading were not associated with achieving R0 resection of presacral recurrences of rectal cancer (all P>0.05), whereas primary tumor pN stage, anatomic staging of presacral recurrence, and procedure for managing presacral recurrence were associated with rate of R0 resection (all P<0.05). According to multifactorial analysis, the pathological stage of the primary tumor pN1-2 (OR=3.506, 95% CI: 1.089-11.291, P=0.035), type of procedure (transabdominal resection: OR=29.250, 95% CI: 2.789 - 306.811, P=0.005; combined abdominal perineal resection: OR=26.000, 95% CI: 2.219-304.702, P=0.009), and anatomical stage of presacral recurrence (Type III: OR=16.000, 95% CI: 1.542 - 166.305, P = 0.020; type IV: OR= 36.667, 95% CI: 3.261 - 412.258, P = 0.004) were all independent risk factors for achieving radical resection of anterior sacral recurrence after rectal cancer surgery. Conclusion: Stage of presacral recurrences of rectal cancer is an independent predictor of achieving R0 resection. It is possible to predict whether radical resection can be achieved on the basis of the patient's medical history.

INTRODUCTION:
We report outcomes of patients with oesophageal cancer treated with neoadjuvant chemoradiotherapy (NACRT) plus surgery or definitive chemoradiotherapy (chemoRT) at our institution.
METHODS:
We retrospectively reviewed patients who underwent chemoRT from 2005 to 2017. The primary outcome was overall survival (OS). Secondary outcomes were disease-free survival (DFS) and toxicities.
RESULTS:
We identified 96 patients with median age of 64 years and squamous cell carcinoma in 82.3%. Twenty-nine patients (30.2%) received NACRT plus surgery, 67 patients (69.8%) received definitive chemoRT. Median follow-up was 13.5 months. The 3/5-year OS were 26.4%/13.4%, and 59.6%/51.6% in the definitive chemoRT and NACRT plus surgery groups, respectively. The 3/5-year DFS were 19.3%/12.3%, and 55.7%/37.2% in the definitive chemoRT and NACRT plus surgery groups, respectively. NACRT plus surgery significantly improved OS (hazard ratio [HR] 0.40, 95% confidence interval [CI] 0.22-0.72,
CONCLUSION
NACRT plus surgery improved OS and DFS. However, in view of treatment-related complications, careful selection of patients is warranted. With the predominant histology of our cohort being squamous cell carcinoma (SCC), our results may be more relevant for those with SCC.

Objective:To explore the clinical manifestations,the type of pathology, treatment and prognosis of laryngeal rhabdomyosarcoma, and to enhance the understanding of the clinical characteristics of the disease, while improving the diagnosis rateand reducing the misdiagnosis rate, in order to explore effective diagnosis and treatment methods. Methods:A retrospective analysis was conducted on the clinical data of 5 cases of laryngeal rhabdomyosarcoma treated in the First Affiliated Hospital of Zhengzhou University from May 2015 to May 2021. Results:All 5 cases of laryngeal rhabdomyosarcoma were misdiagnosed in the early stage. with tumors mostly occurring in the vocal cords and appearing as smooth mass. The clinical symptoms were mostly hoarseness. According to pathological classification, three cases were embryonic type, one case was polymorphic type, and one case was spindle type.Three patients died due to tumor recurrence, one patient had multiple systemic metastases, and another patient who underwent surgical resection in the early stage and supplemented with postoperative radiotherapy and chemotherapyhas been followed up to date without recurrence. Conclusion:Laryngeal rhabdomyosarcoma has low incidence rate, high malignancy degree and poor prognosis. It is easy to be misdiagnosed as a benign mass. Extensive surgical resection combined with radiotherapy and chemotherapy should be performed as soon as possible after diagnosis.

OBJECTIVE:
To study the clinical features of children with recurrent medulloblastoma (MB) and treatment regimens.
METHODS:
A retrospective analysis was performed on 101 children with recurrent MB who were admitted to the hospital from August 1, 2011 to July 31, 2017. The children were followed up to July 31, 2020. The Kaplan-Meier method was used for survival analysis. The Cox regression model was used for multivariate regression analysis.
RESULTS:
Of the 101 children, 95 underwent remission induction therapy, among whom 51 had response, resulting in a response rate of 54%. The median overall survival (OS) time after recurrence was 13 months, and the 1-, 3-, and 5-year OS rates were 50.5%±5.0%, 19.8%±4.0%, and 10%±3.3% respectively. There was no significant difference in the 5-year OS rate between the children with different ages (< 3 years or 3-18 years), sexes, pathological types, or Change stages, between the children with or without radiotherapy before recurrence or re-irradiation after recurrence, and between the children with different times to recurrence (< 12 months or ≥ 12 months after surgery) (
CONCLUSIONS
As for the recurrence of MB, although remission induction therapy again can achieve remission, such children still have a short survival time. Only reoperation can significantly prolong survival time, and therefore, early reoperation can be considered to improve the outcome of children with recurrent MB.
