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.

Telangiectatic osteosarcoma is a rare and special variant of osteogenic sarcoma with distinct radiologic, gross and microscopic features. This tumor is predominantly lytic, destructive tumor without sclerosis on roentgenogram, and is soft and cystic on gross examination. Histologically aneurysmally dilated spaces lined or traversed by stromal cells producing osteoid are noted. This report concerns a case of telangiectatic osteosarcoma occurring in a 7 years old boy. He presented with pathologic fracture of the right distal tibia, followed by a purely lytic lesion on X-ray examination. This lesion recurred five times during a span of one year. Microscopic features of the biopsy specimen was difficult to differentiate from aneurysmal bone cyst because of prominant blood-filled cyst formation. It was finally identified as osteosarcoma from the below-knee amputation specimen through the close examination for anaplastic osteoid-producing stromal cells in the septa that separate the blood cysts.

Locoregional recurrence after breast conservative surgery is not a rare event. However, a metastatic nodule solely at the surgical drain site seems to be extremely unusual. In this report, we present a patient who received a lumpectomy for breast cancer but a metastatic nodule developed at the drain site more than two years after her surgery.

A 41 years female patient was hospitalized with hoarseness for three months, without cough, expectoration and dyspnea. The symptom had no relief by application of antibiotics. Electronic laryngoscope showed that there were the grey neoplasms under subglottic anteriou commissure with broad base and slightly rough surface, and bilateral vocal cords were normal; throat CT showed subglottic irregular high density and calcification. The subglottal tumor resection was performed under the general anesthesia and laryngoscope CO2 laser assisted. In the operation, we found that the tumor was hard with surface of thin mucosa tissue, and there was white bone tissue under it. The removing tumor was about 0. 8 cm X 0. 6 cm X 0. 3 cm and was diagnosed as subglottic osteoma by pathologic examine. There was no recurrence in three months follow-up.

OBJECTIVETo investigate the relationship between extranodal tumor deposits and prognosis in patients with colorectal cancer.

METHODSThe literatures on extranodal tumor deposits and postoperative survival rate in patients with colorectal cancer published at home and abroad from 1990 to 2014 were retrieved in 15 English literature databases such as MEDLINE/PubMed, Web of Science, Directory of Open Access Journals(DOAJ), SpringerLink and Chinese literature databases such as Chinese Biomedical Literature Database CD-ROM, China National Knowledge Infrastructure (CNKI) Database with the internet platform of Yonsei University Library. After screening for inclusion, data extraction and quality assessment, meta-analysis was conducted by the Review Manager 5.3 software.

RESULTSThere were 10 studies meeting the inclusion criteria for meta-analysis. The total sample size of the studies was 4 068 cases with ENTD(+) 727 cases, while ENTD(-) 3 341 cases. Meta analysis showed that 5-year overall survival rate and 5-year relapse-free survival rate were significantly lower in ENTD(+) group than those in ENTD(-) group (OR 0.27, 0.23; 95% CI:0.18 to 0.43, 0.16 to 0.34 respectively, both P=0.000); the 5-year overall survival rates were both significantly lower in ENTD(+) group as compared to ENTD(-) group for patients with N0 and N(+) colorectal cancer (both P<0.05).

CONCLUSIONExtranodal tumor deposits is a poor prognostic factor of patients with colorectal cancer.

OBJECTIVETo analyse the correlation between the micrometastasis and early recurrence and prognosis in laryngeal cancer.

METHODSTotal of 126 patients with laryngeal squamous cell carcinoma were included in the study. The micrometastasis was detected with hematoxylin and eosin staining (HE) and immunohistochemical staining for cytokeratin (CK) of the lymph node specimens after selective neck dissection (II-IV). Chi-square test was used to analyse the relationship between the micrometastasis and early recurrence and prognosis, and Kaplan-Meier method was used for survival analysis.

RESULTSHE staining showed positive micrometastasis in 41 cases and negative micrometastasis in 85 cases in which 33 cases were positive staining for CK. With a following-up of mean 6.3 years, recurrence or metastasis occurred in 15 cases with positive micrometastasis detected by HE staining, 14 cases with CK positive staining and 4 cases with CK negative staining. The correlation between micrometastasis and early recurrence was significant (P < 0.01). The total 5-year survival rate was 79.8%, 10-year survival rate was 60.5%. The 10-year survival rate (52.1%) of the patients with CK positive staining indicating micrometastasis was significantly higher than that of CK negative patients (81.2%, P < 0.01).

CONCLUSIONCervical micrometastasis predicts poor prognosis and early recurrence in patients with laryngeal squamous cell carcinoma.

OBJECTIVETo discuss the present status and progress of clinical research on recurrence of gastric cancer after surgery, including patterns, clinicopathologic factors, prognosis, detection, diagnosis, prevention, and treatment strategies.

DATA SOURCESThe data used in this review were mainly from PubMed articles published in English from 2000 to August 2011. The search terms were "gastric cancer" and "recurrence".

STUDY SELECTIONArticles were selected if they involved clinicopathologic factors, detection methods, and treatment strategies of recurrence of gastric cancer.

RESULTSPeritoneal recurrence is the most common pattern in recurrence of gastric cancer. The main risk factors for recurrence of gastric cancer are tumor stage, including depth of tumor invasion and lymph node metastasis, and Borrmann classification. The prognosis of patients with recurrence is very poor, especially patients with peritoneal recurrence. Systemic chemotherapy is still the main treatment method for patients with recurrent cancer. If complete resection can be accomplished, some benefits may be obtained from surgery for recurrence. However, standard treatment for patients with recurrence has not yet been established.

CONCLUSIONSEarly detection and diagnosis of recurrence is quite crucial for treatment and prognosis. The optimal therapeutic strategy for recurrence should be based on a multidisciplinary assessment and the patient's individual state and should involve combined therapy.
