We reported a case of children's OSAHS caused by the huge fibrolipoma in pharynx nasalis. The patient was a 10-years-old child who went to the hospital with the chief complaint of "Snoring and mouth breathing during sleep for 10 years". Imaging tests found one huge tumor in pharynx nasalis before the operation. The tumor was resected totally. The postoperative pathological diagnosis was fibrolipoma. No recurrence was noted during the follow-up visit one year postoperatively. The clinical features, diagnosis, treatment, pathology and prognosis were reviewed herein.

We report an unusual case of acute myelogenous leukemia in a patient who showed an extramedullary relapse in her uterus, without bone marrow recurrence, two years after an allogeneic bone marrow transplant. She complained of irregular vaginal spotting, and magnetic resonance imaging demonstrated a uterine mass. A biopsy revealed a massive infiltration of immature myeloid cells. A variable number of tandem repeats (VNTR) based on an examination of peripheral blood cells showed full donor chimerism. After receiving chemotherapy, her uterine mass had completely resolved. She has remained in complete remission for more than 6 months. This case suggests that physicians should be aware of the possibility of a uterine relapse in female bone marrow transplant recipients with acute myelogenous leukemia.

Prostate cancer is one of the most common malignancies threatening men's health, and the mechanisms underlying its initiation and progression are poorly understood. Last decade has witnessed encouraging progress in the studies of prostate cancer stem cells (PCSCs), which are considered to play important roles in tumor initiation, recurrence and metastasis, castration resistance, and drug resistance. Therefore, a deeper insight into PCSCs is of great significance for the successful management of prostate cancer. This article presents an overview on the location, origin, and markers of PCSCs as well as their potential correlation with tumor metastasis and castration resistance.

Gastric stump cancer was initially defined as a carcinoma of the stomach occurring more than 5 years after surgery for gastric or duodenal benign disease. In recent years, as the number of total gastrectomy for benign disease has gradually decreased and the gastric cancer detection and operation rate have annually increased, residual recurrence of primary gastric cancer more than 10 years after gastric cancer surgery has also been considered as gastric stump cancer. The incidence of gastric stump cancer is increasing annually. The epidemiological characteristics of this form of cancer are also developing, and they show a higher incidence in males compared to females. The incidence has been affected following digestive tract reconstruction, and the risk increases in patients who undergo Billroth II( reconstruction. The interval of onset is related to the benign and malignant condition of primary disease, and the incidence increases after 10 years of early gastric cancer surgery. Lymph node metastasis pattern in gastric stump cancer is different from that in primary gastric cancer as the primary operation may destroy normal lymph flow. Many factors are known to cause gastric stump cancer, mainly duodenal gastric reflux, Helicobacter pylori infection, and gastric mucosal barrier dysfunction; however, the mechanism is not clear. It is expected to reduce the incidence of gastric stump cancer by taking precautionary measures against different inducements, which also has some guiding significance for the treatment and prognosis of gastric cancer.

Radical gastrectomy combined with perioperative comprehensive treatment is the main curable strategy for gastric cancer patients, and postoperative complications are the issue that gastric surgeons have to face. Complications not only affect the short-term postoperative recovery, but also facilitate tumor recurrence or metastasis, thus resulting in poor prognosis. Therefore, unifying the diagnostic criteria for postoperative complications, bringing the surgeons' attention to complications, and understanding the potential mechanism of complications undermining long-term survival, will be helpful to the future improvement of the clinical diagnosis and treatment as well as prognosis for gastric cancer patients in China. Meanwhile, surgeons should constantly hone their operative skills, improve their sense of responsibility and empathy, and administer individualized perioperative management based on patients' general conditions, so as to minimize the occurrence of postoperative complications and their influence on prognosis.

OBJECTIVETo investigate the risk factors for local recurrence and distant metastasis after radical anterior resection for rectal cancer.

METHODSClinicopathological data of 957 patients who underwent radical anterior resection for rectal cancer from 1983 to 2000 were reviewed retrospectively. The risk factors for local recurrence and distant metastasis were analyzed.

RESULTSThere were 150 recurrent or metastatic cases (15.7%) after radical resection during a median follow- up of 71 months. Recurrence and metastasis sites included pelvics(6.0%, n=57), liver (4.9%, n=47), lung (4.2%, n=40) and other sites (0.6%, n=6). The median recurrent interval was 18 months (2-85 months),with a median survival of 8 months (1-62 months) after recurrence. Re-resection of the tumors was performed in 23 patients(15.3% ), and the median survival of such patients was 30 months with a 5- year survival rate of 13.0%. There were significant differences in recurrence and metastasis considering age,family history of tumor,CEA level,T staging,lymph node metastasis,venous cancerous emboli and signet cell carcinoma or mucinous adenocarcinoma. Logistic regression analysis revealed that family history (P=0.001), high CEA level (P=0.033), T3- 4 (P=0.000), lymph node metastasis (P=0.000),venous cancerous emboli (P=0.001),and signet cell carcinoma or mucinous adenocarcinoma (P=0.012) were risk factors for recurrence and metastasis.

CONCLUSIONSThere are several risk factors for recurrence after radical anterior resection for rectal cancer. The main recurrent or metastatic sites are pelvis,liver and lung. Resection of recurrent tumor can prolong the survival.

OBJECTIVETo assess the effect of laparoscopic colectomy on the exfoliated cancer cells in peritoneal cavity, recurrence and metastasis of patients with colonic carcinoma.

METHODSOne hundred and fifty-nine patients with colonic cancer proven by colonoscopy and pathology were divided into two groups based on patient's preference: laparoscopic group (n=74) and open group (n=85). The positive rate of exfoliated cancer cells in peritoneal cavity was compared by cytological detection before and after cancer resection. Recurrence, metastasis rate and 3-year survival were compared between the two groups.

RESULTSThe positive rates of exfoliated cancer cells in peritoneal cavity were 12.2% (9/74) in the laparoscopic group and 15.3% (13/85) in the open group before cancer resection without significant difference (P=0.718); 20.3% (15/74) and 30.6% (26/85) after cancer resection without significant difference (P=0.138). The follow-up ranged from 4 to 45 months. The 3-year local recurrence rates were 13.6% (8/59) and 8.8% (6/68) (P=0.455), the 3-year distal metastasis rates were 11.9% (7/59) and 17.6% (12/68) (P=0.416) and the 3-year survival rates were 79.7% and 80.0% (P=0.998), and the differences were not statistically significant.

CONCLUSIONThe laparoscopic operation does not increase the recurrence and metastasis rate and results in similar survival in patients with colonic cancer as compared to open procedure.

OBJECTIVETo discuss the factors predicting recurrence after local excision for low rectal cancer.

METHODMedical records and follow-up histories of 97 patients undergone local excision of adenocarcinoma of the rectum between April, 1975 and April, 2005 in Cancer Hospital of the Chinese Academy of Medical Sciences were reviewed retrospectively.

RESULTSPostoperative pathologic examination revealed 28 pTis cases, 48 pT(1) cases, and 21 pT(2) cases. Eighty-nine patients underwent transanal excision, 7 transsacral excision, and 1 transvaginal excision. Twenty-two(45.8%) patients with T(1) tumors and 14(66.7%) patients with T(2) tumors were treated with postoperative radiotherapy with or without 5-fluorouracil. Seventeen(17.5%) patients presented recurrence, including 13 local recurrence, 2 local and distant recurrence, and 2 distant recurrence. The local recurrence rate was 15.5%. Median time to relapse was 27 months(range 4-73). The incidence of local recurrence were 7.1%, 12.5%, and 33.3% for patients with pTis, pT(1), and pT(2)(P=0.031) respectively. The local recurrence rate was 10.5%, 13.7%, and 3/5 for patients with pedunculated, sessile, and ulcerative carcinoma(P=0.017). The local recurrence of patients with T(2) tumors treated via local excision with or without chemoradiotherapy was 21.4%(3/14) and 4/7, but the difference was no significance(P=0.127). All the 15 patients with local recurrence underwent salvage resection, and the 5-year survival rate after salvage surgery was 59.6%.

CONCLUSIONSHigher rates of recurrence are seen in patients with T(2) tumors and ulcerative carcinoma. Chemoradiotherapy or radical surgery should be chosen for T(2) tumors following local excision. Salvage resection should be considered after local recurrence.

Background: Decision-making concerning the treatment of choroid plexus tumor (CPT) in pediatric patients remains a topic of considerable debate. The aim of this work was to describe clinical features and prognostic risk factors of CPT in the pediatric population and to provide theoretical opinions regarding clinical decisions for CPT. Methods: The data of 96 patients with CPT and younger than 14 years were retrospectively analyzed. Clinical characteristics such as pathological type of CPTs, rate and severity of hydrocephalus, treatment and outcome, and recurrence were investigated. For categorical variables, the Pearson's Chi-square test was performed. The Mann-Whitney U-test was used for comparisons between nonnormally distributed parameters. Log-rank test was used for progression-free survival (PFS). Results: The study included 70 choroid plexus papilloma (CPP) cases, 17 atypical choroid plexus papilloma (aCPP) cases, and 9 choroid plexus carcinoma (CPC) cases. Compared with patients with CPP or aCPP, patients with CPC had a shorter disease course (median: CPP, 4 months; aCPP, 2 months; CPC, 1 month; H: 23.5, P < 0.001), higher rate of acute hydrocephalus (CPP, 27.1%; aCPP, 52.9%; CPC, 77.8%; χ = 10.9, P < 0.05), and lower incidence of cure rate (CPP, 85.7%; aCPP, 70.5%; CPC, 33.3%; χ = 13.5, P < 0.05). The severity of hydrocephalus with tumor in the lateral or third ventricle was significantly higher than that with tumors in the fourth ventricle (severe hydrocephalus: lateral ventricle, 51.7%; third ventricle, 47.0%; fourth ventricle, 11.1%; χ = 26.0, P < 0.001). Patients with gross total surgical resection had no better PFS than those with partial resection because of the use of adjuvant therapy in the latter (χ = 4.0, P > 0.05). Patients with CPC experienced shorter time for recurrence than those with CPP or aCPP (χ = 40.1, P < 0.0001). Conclusions Our results indicated that CPP in the fourth ventricle could trigger serious clinical symptoms at an early stage, requiring early intervention. Adjuvant treatment might be necessary for patients with partially resected CPP, aCPP, and CPC to achieve a favorable outcome.
