Objective: To explore the diagnosis, surgical management and outcome of jugular foramen chondrosarcoma (CSA). Methods: Fifteen patients with jugular foramen CSA hospitalized in the Department of Otorhinolaryngology Head and Neck Surgery of Chinese PLA General Hospital from December 2002 to February 2020 were retrospectively collected,of whom 2 were male and 13 were female, aging from 22 to 61 years old. The clinical symptoms and signs, imaging features, differential diagnosis, surgical approaches, function of facial nerve and cranial nerves IX to XII, and surgical outcomes were analyzed. Results: Patients with jugular foramen CSA mainly presented with facial paralysis, hearing loss, hoarseness, cough, tinnitus and local mass. Computed tomography (CT) and magnetic resonance (MR) could provide important information for diagnosis. CT showed irregular destruction on bone margin of the jugular foramen. MR demonstrated iso or hypointense on T1WI, hyperintense on T2WI and heterogeneous contrast-enhancement. Surgical approaches were chosen upon the sizes and scopes of the tumors. Inferior temporal fossa A approach was adopted in 12 cases, inferior temporal fossa B approach in 2 cases and mastoid combined parotid approach in 1 case. Five patients with facial nerve involved received great auricular nerve graft. The House Brackmann (H-B) grading scale was used to evaluate the facial nerve function. Preoperative facial nerve function ranked grade Ⅴ in 4 cases and grade Ⅵ in 1 case. Postoperative facial nerve function improved to grade Ⅲ in 2 cases and grade Ⅵ in 3 cases. Five patients presented with cranial nerves Ⅸ and Ⅹ palsies. Hoarseness and cough of 2 cases improved after operation, while the other 3 cases did not. All the patients were diagnosed CSA by histopathology and immunohistochemistry, with immunohistochemical staining showing vimentin and S-100 positive, but cytokeratin negative in tumor cells. All patients survived during 28 to 234 months' follow-up. Two patients suffered from tumor recurrence 7 years after surgery and received revision surgery. No complications such as cerebrospinal fluid leakage and intracranial infection occurred after operation. Conclusions: Jugular foramen CSA lacks characteristic symptoms or signs. Imaging is helpful to differential diagnosis. Surgery is the primary treatment of jugular foramen CSA. Patients with facial paralysis should receive surgery in time as to restore the facial nerve. Long-term follow-up is necessary after surgery in case of recurrence.

Currently, the standard of clinical complete response (cCR) after neoadjuvant chemoradiotherapy (nCRT) for local advanced rectal cancer generally lacks pathological examination, the cCR judged by the current standard is still far from the real pathological complete response. After nCRT, due to the presence of tissue edema and fibrosis, MRI is highly uncertain in determining the staging of local lesions. The precision of colonoscopy biopsy is generally low because residual cancer foci exist primarily in the muscular layer, which limits the determination of cCR by colonoscopy biopsy. Local excision through the anus can resect the whole intestinal wall tissue, which is relatively accurate and close to the real state of remission of the lesion, but there are many problems, such as affecting anal function, high rate of complications, and increased difficulty of following radical surgery. Based on the present diagnosis of cCR, the authors put forward the concept of modified cCR (m-cCR) which combined with the pathological standard of transanal multipoint full-layer puncture biopsy. It is possible to improve the accuracy of cCR, and improve the safety of cCR patients who receive wait-and-watch therapy without increasing complications or affecting anal function. The exact conclusion needs to be confirmed by further studies.

OBJECTIVE: To determine the optimal cystoscopic frequency for intermediate-risk non-muscle invasive bladder cancer. METHODS: Patients with intermediate-risk non-muscle invasive bladder cancer, who underwent transurethral resection of bladder tumor in Peking University People's Hospital from January 2001 to October 2019, were retrospectively analyzed. Their clinical, pathological and follow-up data were collected. In postoperative 2-year period, the patients were underwent cystoscopy every 3 to 6 months. Depending on recurrence and progression of the patients, we hypothesized three strategies of surveillance intensity in the first 2 years after surgery: model 1: 3-month intervals, model 2: 6-month intervals, and model 3: 12-month intervals. The differences in the numbers and time of delayed detection of recurrence and progression were compared among the three models. RESULTS: A total of 185 patients were enrolled, including 144 males (77.8%) and 41 females (22.2%). The median age was 68 (59-76) years. There were 118 cases (63.8%) with single tumor and 67 cases (36.2%) with multiple tumor. Of the patients 179 (96.8%) had stage Ta and 6 (3.2%) had stage T1. There were 108 cases (58.4%) with high-grade disease and 77 cases (41.6%) with low-grade disease. During the follow-up period of the first 2 years, 52 patients (28.1%) had recurrence, 133 cases (71.9%) had no recurrence, 11 cases (5.9%) had progression and 174 cases (94.1%) had no progression. Compared with model 1, 29 (55.8%) delayed detection of recurrence in model 2 vs. 41 (78.8%) delayed detection of recurrence in model 3, and the difference was statistically significant (P=0.012). The median delayed time of detecting recurrence was 1.00 months in model 1, 1.99 months in model 2 and 4.19 months in model 3, respectively. There were statistically significant differences between mode 1 and model 3 (P=0.001), and between model 2 and model 3 (P=0.013). Compared with model 1, 5 (45.4%) delayed detection of progression in model 2 vs. 8 (72.7%) delayed detection of progression in model 3, and the difference was not statistically significant. The median delayed time of detecting progression was 1.00 month in model 1, 2.00 months in model 2 and 3.00 months in model 3, respectively. There was no statistically significant difference among them. CONCLUSION Although providing slightly slower detection of tumor recurrence and progression, compared with 3-month intervals of cystoscopy, 6-month intervals do not result in serious adverse outcomes and reduce cost and pain of the patients, which is feasible in intermediate-risk non-muscle invasive bladder cancer.

OBJECTIVES: This study aims to explore the clinical and pathological characteristics of congenital granular cell tumors and provide some references for clinical diagnosis, differential diagnosis, and treatment. METHODS: Nine ca-ses of congenital granular cell tumors who visited the Children's Hospital of Zhejiang University School of Medicine from February 2008 to March 2022 were retrospectively analyzed. Herein, its clinical characteristics, pathological characteristics, treatment, and prognosis were summarized and analyzed. RESULTS: We found that nine patients were all female, aged 1‑38 days when they saw the doctor. Three of them were attached in maxillary and the other six were attached in mandible. Meanwhile, six tumors were found during the mother's pregnancy at 28-39 weeks and three tumors were found at the baby's birth. One case was excised surgically under local anesthesia, and the other cases were excised surgically under general anesthesia. After 1 month to 12 years of follow-up, patients have no recurrence, however, two cases emerged new teeth from the tumor resection site. Histopathology of all excised lesions was congenital granular cell lesion. CONCLUSIONS Congenital granular cell tumor is a benign tumor and the prognosis is good. Therefore, surgical resection of the tumor can be done without extensive resection, and it generally does not relapse. Thus, ultrasonography during pregnancy is an important method for the early detection of congenital granular cell epulis.

Lateral lymph node metastasis represents a major cause of local pelvic recurrence after curative resection for mid-low rectal cancer. Considerable controversies over issues remain among eastern and western countries, with respect to the diagnosis of lateral lymph node metastasis, the multidisciplinary management regime, indication for lateral pelvic lymph node dissection, and the prognosis of surgical dissection. The purpose of this expert consensus is to improve the understanding of this condition among Chinese specialists, and to help standardizing the diagnosis and therapeutic strategies for lateral lymph node metastasis. Each statement and recommendation in this consensus were generated based on suggestions from at least three experts, agreed by a majority of experts from the Chinese expert panel. The evaluation criteria by U.S. Preventive Services Task Force was adopted for the grading of recommendations. In respect to the aforementioned controversies, the present consensus produced 21 statements on diagnosis and treatment for lateral lymph node metastasis. The pending issues in this consensus need further high-quality clinical practice and research.

To explore the clinical features, pathological features, gene test results, diagnosis, treatment and prognosis of Peutz-Jeghers syndrome(PJS).
 Methods: We retrospectively analyzed clinical data of 46 hospitalized cases of PJS during 2007 and 2017.
 Results: All 46 patients had mucocutaneous melanin pigmentation and multiple gastrointestinal polyposis. The pigmentation was first noticed often within 5 years old, and 14 cases had family history. The clinical manifestations mainly included black spots, abdominal pain, hematochezia, and anemia. Histological examinations showed that 20 patients were classified as hamartomatous polyps,18 as adenomatous polyps, 14 as inflammatory polyps, and 10 as zigzag polyps. Eleven patients sequenced a panel of 20 genes previously associated with colorectal cancer (CRC) by next-generation sequencing, and the results showed 5 patients with gene mutations, and 3 of them with intussusception and surgical histories were found to have pathogenic germline mutations in the STK11 gene. Endoscopic treatment was the main therapy, but endoscopy combined with laparoscopy or surgical treatment was performed when complications occurred or the polyp was too large. Malignant tumors were found in 3 patients during follow-up.
 Conclusion: PJS is a hereditary disease which is characterized by spots of the skin or mucosa and gastrointestinal multiple polyps. The main pathological features are hamartoma and adenoma. The risks for intussusception and surgical operation are found to be high in the patients with pathogenic germline mutations in the STK11 gene. Endoscopic treatment is the main therapy. PJS patients should be followed up regularly due to the increasing risk for cancer and being easily to relapse.

ObjectiveTo explore the practicability and safety of the F4.8 visual miniature nephroscope in the diagnosis and treatment of hematospermia.

METHODSThis study included 12 cases of refractory hematospermia accompanied by perineal or lower abdominal pain and discomfort. All the patients failed to respond to two months of systemic anti-inflammatory medication and local physiotherapy. Seminal vesicle tumor and tuberculosis were excluded preoperatively by rectal seminal vesicle ultrasonography, MRI or CT. Under epidural anesthesia, microscopic examination was performed with the F4.8 miniature nephroscope through the urethra and ejaculatory duct orifice into the seminal vesicle cavity, the blood clots washed out with normal saline, the seminal vesicle stones extracted by holmium laser lithotripsy and with the reticular basket, the seminal vesicle polyps removed by holmium laser ablation and vaporization, and the seminal vesicle cavity rinsed with diluted iodophor after operation.

RESULTSOf the 10 patients subjected to bilateral seminal vesiculoscopy, 3 with unilateral and 2 with bilateral seminal vesicle stones were treated by holmium laser lithotripsy, saline flushing and reticular-basket removal, 2 with seminal vesicle polyps by holmium laser ablation and vaporization, and the other 3 with blood clots in the seminal vesicle cavity by saline flushing for complete clearance. The 2 patients subjected to unilateral seminal vesiculoscopy both received flushing of the seminal vesicle cavity for clearance of the blood clots. The operations lasted 10－55 (25 ± 6) minutes. There were no such intra- or post-operative complications as rectal injury, peripheral organ injury, and external urethral sphincter injury. The urethral catheter was removed at 24 hours, anti-infection medication withdrawn at 72 hours, and regular sex achieved at 2 weeks postoperatively. The patients were followed up for 6－20 (7 ± 2.3) months, during which hematospermia and related symptoms disappeared in 10 cases at 3 months and recurrence was observed in the other 2 at 4 months after surgery but improved after antibiotic medication.

CONCLUSIONSThe F4.8 visual miniature nephroscope can be applied to the examination of the seminal vesicle cavity and treatment of seminal vesicle stones and polyps, with the advantages of minimal invasiveness, safety and reliability.

OBJECTIVE: To investigate the clinical characteristics and prognostic factors of reoperation patients with postoperative recurrence or metastasis of gastrointestinal stromal tumor (GIST). METHODS: A retrospective case-control study was performed on the clinical data of 31 patients with GIST who had recurrence or metastasis after the first surgery and underwent one or more operations again from February 2003 to January 2016 at Ruijin Hospital, Shanghai Jiaotong University School of Medicine. The clinical characteristics of these patients were analyzed. Kaplan-Meier survival curve was used to calculate the survival rate, Cox univariate and multivariate regression model was applied to prognosis analysis. RESULTS: Age of these 31 patients at the first operation was 35-78 (median 49) years, including 17 males (54.8%) and 14 females (45.2%). The tumors of 21 cases located in small intestines (67.7%), 2 cases in stomach (6.5%), 4 cases (12.9%) in colorectum and of 4 cases (12.9%) in other sites. According to NIH criteria, risk assessment indicated 26 cases were(83.8%) with high risk, 3 cases (9.7%) with moderate risk, and 2 cases (6.5%) with low risk. After the first operation, 15 cases received the IM (imatinib) therapy regularly based on NCCN guideline,10 cases received the therapy irregularly, and the other 6 cases did not receive the therapy. R0 resection was performed in 29 cases (93.5%) and R1/R2 resection was performed in 2 cases (6.5%). The median interval between the first operation to the recurrence was 32.3 (5.2-117.6) months and the median age of recurrence was 56 years old. Refer to the recurrent location, 28 cases (90.3%) were found in the same location or liver, 1 case in greater omentum, and 2 cases in pelvic cavity. The median diameter of the tumor in reoperation was 6.5 cm. Twenty-three cases(74.2%) received R0 excision and the other 8 cases(25.8%) received R1/R2 excision. At diagnosis of tumor recurrence, 20 cases (64.5%) received the second surgery immediately and the other 11 cases received surgery after imatinib or sunitinib treatment. Twenty-nine (93.5%) patients were followed up for 7.3 to 160.3 (median 49.5) months. After the second surgery, the relapse-free survival (RFS) of the whole group was 3.2 to 148.6(median: 29.7) months. Till the end of follow-up, 9 cases died of recurrence. Among 20 alive cases, 8 cases were living with the tumor, 1 case received the third surgery. The median overall survival (OS) time was 38.4(6.2-160.3) months. The 5-year RFS and the 5-year OS of 15 cases who received regular targeted therapy after the first operation were 73.4% and 81.7% respectively, significantly higher than those of the other 16 cases who received irregular or no targeted therapy(37.6%, P=0.015 and 38.9%,P=0.023,respectively). The 5-year RFS rate and the 5-year OS rate of the 11 patients who were diagnosed or complicated with liver metastasis were 29.8% and 32.2% respectively, which were significantly lower than those of the 20 patients without liver metastasis (79.1% and 88.1% respectively, both P<0.001). Cox model for OS, the results showed that regular targeted therapy after first surgery(HR=0.362, 95%CI:0.210-1.074, P=0.089) and the liver metastasis (HR=5.342, 95%CI: 0.902-12.580, P=0.057) were not the independent risk factors. CONCLUSIONS Regular targeted therapy according to the guideline after the first operation for GIST patients with recurrence or metastasis may improve the prognosis. Prognosis of GIST patients with postoperative liver metastasis is poor.

The Chinese Consensus on Endoscopic Diagnosis and Management of Gastrointestinal Submucosal Tumors is the first guideline in the area of gastrointestinal submucosal tumors(SMT) in China. SMTs of the Gastrointestinal tract are bulge lesions that originate from muscularis mucosa, submucosa, or muscularis propria. Endoscopic treatment of SMT is an effective way to improve the quality of life for patients, to reduce the burden on patients' families and the society, and to save national medical resources. For these reasons, this consensus has proposed the indications for endoscopic resection, on the basis of current status of diagnosis and treatment for SMT in China, and in combination with domestic and foreign literature and experts' experience:(1)For tumors with malignant potential suspected by preoperative examination or pathologically confirmed through biopsy, endoscopic resection should be considered when technically possible; (2) Endoscopic resection is indicated for SMT with symptoms (e.g. hemorrhage and obstruction); (3) For benign tumors suspected by preoperative examinations or confirmed by pathological examination, endoscopic resection could be considered when patients cannot attend regular follow-up, tumors grow rapidly in a short period or patients have a strong willing for endoscopic treatment. After endoscopic resection for SMT, different treatment algorithms should be recommended according to pathological types:(1)For benign lesions, such as lipoma and leiomyoma, postoperative routine treatment and follow-up are recommended;(2)For SMT without malignant potential, such as well-differentiated rectal neruoendocrine tumors (NET) that are < 1 cm, survival rate after complete resection is approximately 98.9%-100% and the recurrence rate is extremely low. Therefore, routine follow-up is recommended when the margin were confirmed negative pathologically; (3)Low-malignant-potential SMT, such as low-risk GIST, should be assessed by endoscopic ultrasonography or imaging every 6-12 months, and then managed according to clinical instructions; (4)Medium/high-malignant-potential SMT, such as type 3 and type 4 gastric NET, colorectal NET that are >2 cm, and medium/high-risk GISTs, additional treatment is required according to the guidelines for each specific disease. This expert consensus aims to provide an endoscopic SMT diagnosis and treatment standard,which fits our current national status, to domestic hospitals at all levels.
