Grade G2 Rectal Neuroendocrine Tumor Is Much More Invasive Compared With G1 Tumor.

Background: To compare clinicopathologic feature of rectal neuroendocrine tumor (NET) grade G1 with G2 NET.

Methods: Six hundred-one cases of rectal G1 and G2 NETs diagnosed in our center were analyzed.

Results: Of 601 cases of rectal NET, 515 cases were with grade G1 and 86 cases were with grade G2.

Very Early Colorectal Anastomotic Leakage within 5 Post-operative Days: a More Severe Subtype Needs Relaparatomy.

Early anastomotic leakage (AL), usually defined as leakage within 30 post-operative days, represents a severe entity. However, mounting evidence has indicated that majorities of leakage occur within one week after surgery, making late AL rarity. Here we analyzed 101 consecutive colorectal AL, all of which occurred within 30 post-operative days, during Jan 2013 and Dec 2015 in cancer hospital of Fudan University.

The Prognostic Value of Preoperative Serum CEA and CA19-9 Values in Stage I-III Colorectal Cancer.

Background/aims: There is disagreement about the prognostic value of serum carcinoembryonic antigen (CEA) and carbohydrate antigen 19-9 (CA19-9) in patients who have stage I-III colorectal cancer. Therefore, we investigated the relationship between preoperative serum CEA and CA19-9 levels and clinical outcome in patients with this disease.

Methodology: The study included 724 patients who had received radical resection for stage I-III colorectal cancer in Fudan University Shanghai Cancer Center.

[Prognosis of patients with early enteral nutrition after gastrointestinal operation: a meta-analysis].

Objective: To systematically assess the effect of early enteral nutrition support after gastrointestinal operation on prognosis.

Methods: The Cochrane Library, PubMed, CBM, CNKI, Wanfang, and VIP databases were retrieved via computer system for randomized controlled trails(RCTs) with early enteral nutrition support to patients undergoing gastrointestinal operation. Quality of studies was evaluated by the Cochrane Jadad rating scale.

Retrospective analysis of perianal Paget's disease with underlying anorectal carcinoma.

Aim: To analyze clinical and pathological characteristics of an aggressive subtype of perianal Paget's disease (PPD) and explore its rational treatment modalities.

Methods: PPD patients were retrospectively collected in the institutional colorectal database of the Fudan University Shanghai Cancer Center. Detailed patient histories of past medical condition, diagnosis, treatment, and pathological findings were reviewed.

Predicting prognosis of rectal cancer patients with total mesorectal excision using molecular markers.

Aim: To explore the prognostic variables in rectal cancer patients undergoing curative total mesorectal excision and the effect of postoperative chemotherapy in advanced rectal cancer.

Methods: A total of 259 consecutive rectal cancer patients treated with curative total mesorectal excision between 1999 and 2004 were collected. p53, p21, PCNA, and CD44v6 were examined using immunohistochemistry (IHC).

Chordee without hypospadias: report of 79 Chinese prepubertal patients.

A series of Chinese prepubertal patients with congenital chordee without hypospadias is presented and the clinical data described. From July 1999 to September 2006, 79 boys with congenital chordee without hypospadias were treated in the Department of Pediatric Surgery, West China Hospital of Sichuan University, China.

[Analysis of shape and retractability of the prepuce in 1,015 Chinese boys aged from 0 to 18 years old].

Objective: To evaluate the characteristics of the preputial development in Chinese boys and indications as well as occasion of circumcision.

Methods: The shape and retractability of prepuce were evaluated in 1,015 Chinese boys from 0 to 18 years old without heteroplasia of prepuce and penis.

Results: Ratio of children with phimosis decreases progressively with increasing age, from 64.
