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.

OBJECTIVETo investigate a non-invasive, effective and rapid mode of detecting the recurrence of bladder cancer during follow-up.

METHODSNinety patients following transurethral resection of bladder tumor (TURBt) surgery were recruited from January 1998 to March 2000. Standard ELISA was used to determine the quantity of nuclear matrix protein (NMP-22) in urine of all bladder cancer patients during their follow-up periods. Urine bladder tumor antigen (BTA) stat test was simultaneously performed and followed by cystoscopy.

RESULTSThe total positive rates of urinary NMP-22 and BTA stat test were 76.7% (33/43) and 67.4% (29/43), respectively. Comparatively, this positive rate would increase to 93.0% (40/43) when the combination of both urine NMP-22 and BTA test were adopted.

CONCLUSIONExamination of NMP-22 in urine is a rapid and effective way to detect the recurrence of bladder cancer. If combined with BTA test, NMP-22 may be used as a non-invasive method in surveillance of recurring of bladder cancer, which may reduce the frequency of patients needing to undergo conventional invasive cystoscopy.

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.

OBJECTIVE: To investigate the clinical diagnosis, treatment and prognosis of carcinoma showing thymus-like differentiation (CASTLE) of thyroid, and to improve the understanding of CASTLE. METHOD: In 6 patients with CASTLE, we performed region VI lymph node dissection, the lesion resection of thyroid lobe and isthmus. After the operation, except one case of 68 years old patient, the rest patients were treated with radiotherapy 60 Gy in anterior cervical region after third week of operation and 5 courses of chemotherapy with cisplatin, each interval of 2 weeks. Insist on the oral Euthyrox. RESULT: All patients were alive without recurrence and metastasis. CONCLUSION The diagnosis of CASTLE depends on the histology and immunohistochemistry. Operation was the main treatment. CASTLE is a rare type of thyroid carcinoma with slow progress and good prognosis.

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.

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.
