T ree cases of sarcomas of theJ we femur were treated by region-a?ir? ation with overdosage of me-chlorethamine for 3 weeks and there-after a high amputation was done,and the distal leg was replantedwith the length that the anklewould act as a knee joint and thefoot pointing backword. Follow-upfor 1 -5 years discovered no me-tastasie of the tumor and the artifi-cial limb showed a better function.
Objective To explore the effect of facial artery musculo-mucosal (FAMM) flap to reconstruct tongue and floor of mouth defects. Methods Between January 2011 and January 2016, 24 cases of tongue and floor of mouth defects were repaired with FAMM flap after tumor resection. There were 16 males and 8 females, aged from 38 to 70 years with an average of 55 years. The disease duration was from 1 week to 6 months with an average of 4 months. The defect located at the floor of mouth in 4 cases, at the tongue in 15 cases, and both tongue and floor of mouth in 5 cases. There were 2 cases of carcinoma at the floor of mouth, 2 cases of adenoid cystic carcinoma at the floor of mouth, 14 cases of carcinoma at the tongue, 1 case of adenoid cystic carcinoma at the tongue, and 5 cases of carcinoma at the tongue and floor of mouth. The size of defect ranged from 4 cm×3 cm to 8 cm×7 cm. Three ipsilateral and 21 contralateral FAMM flaps were harvested (5 cases were repaired with FAMM flap and submental muscle island flap due to the large defect area). The size of FAMM flap ranged from 5 cm×4 cm to 5 cm×5 cm, the size of submental muscle island flap ranged from 4 cm×3 cm to 5 cm×4 cm. Results All flaps survived after operation, without local necrosis. Wound dehiscence at donor site occurred in 5 cases, and healed after cleaning; primary healing was obtained in the other 19 cases. All the patients were followed up 8 months to 5 years with an average of 2 years and 4 months. No obvious facial deformity or fistula of the floor of mouth occurred after operation. Injury of the submandibular branch of the facial nerve was observed in 16 patients, who returned to normal at 3 months. All 24 patients had limitation of mouth opening after operation, which disappeared after 12 months. The functions of speech, chewing, and swallowing were normal. Conclusion FAMM flap has many advantages of simple operation, good repair, high flap survival rate, and less injury at donor site for repairing tongue and floor of mouth defects.
Objective To investigate the effect of tumor suppressor gene on tumourigenesis in multiple primary malignant neoplasm (MPMN).Methods The retrospective analysis was used to summarize several common tumor suppressor genes correlation to MPMN. Results At current study of the tumor suppressor genes, the common genes studied in MPMN were p53, APC, p16, BRCA1, BRCA2 and PTEN/MMAC1, etc. The same mutation of tumor suppressor genes could be detected from PMNNs. Conclusion There are significant relations between MPMN and inactivation of tumor suppressor gene. By the study of tumor suppressor gene, it can reveal some common rules of tumourigenesis of MPMN.
Objective To enhance the understanding of the primary salivary glandtype lung cancer (PSGLC) and improve the diagnostic rate of the disease. Methods The clinical data of 41 patients with PSGLC pathologically confirmed in West China Hospital between October 2009 and October 2015 were analyzed in terms of clinical features, therapy and prognosis. Results All the 41 patients (21 males and 20 females) accounted for 0.22% (41/18 738) of the primary malignant lung tumor diagnosed in the same period. The patients aged from 16 to 72 with the median age of 43.6. The disease course was 1 month to 6 years, and 12 had smoking history. There were 23 cases of adenoid cystic carcinoma, 15 of mucoepidermoid carcinoma and 3 of acinic cell carcinoma. The symptoms, chest-computed tomography and fiberbronchoscopy examination had no specificity. There were 34 patients who had undergone surgery, in whom 3 had fiberbronchoscopy, 4 had oral traditional Chinese medicine treatment, 5 had chemotherapy and radiotherapy at the same time, 9 received chemotherapy only, and 4 recived radiotherapy only. Follow-up period lasted for 2-65 months, with the median time of 38 months. Two patients had recrudescence, 6 patients had distant metastasis and 1 patient died. Conclusions PSGLC have no specific clinical features; its diagnosis basically rely on pathological examination. After comprehensive treatment mainly on surgery, the prognosis of the disease is better than other malignant lung cancers.
Objective To compare the therapeutic effect of percutaneous transhepatic cholangial drainage (PTCD) and operation drainage for the patients with inoperable malignant obstructive jaundice. Methods A total of 131 patients with inoperable malignant obstructive jaundice were treated in this hospital, in which 102 patients had PTCD by placement of metallic stent and (or) plastic tubes to remove obstruction of bile duct (interventional treatment group). Simultaneously 29 patients were selected for operation by intraexternal drainage (operation drainage group). The patients were followed up for comparison of the serum level of total bilirubin, postoperative complications, average length of hospitalization and average cost between the two groups. Results PTCD was successfully performed in all the patients of the interventional treatment group. There were no significant differences of 50% decrease period of average total bilirubin level or postoperative complications between the two groups (Pgt;0.05). The average length of hospitalization and average cost of interventional treatment group were less than those of operation drainage group (Plt;0.05). Conclusions Compare with operation drainage, interventional treatment can reduce average length of hospitalization and average cost, without increase of postoperative complications, which is a main chance of treatment for malignant obstructive jaundice.
目的 研究直肠癌切除后肠吻合前进行肠腔灌洗的临床作用。方法 对我院2006年6月至2007年2月期间连续56例行直肠癌低位前切除吻合的病例在切除原发灶、行远端封闭吻合前行生理盐水远端肠腔灌洗，收集灌洗前、后2份标本分别涂片行细胞学检查。结果 灌洗前收集液中观察到肿瘤细胞或核异形细胞者7例，中性粒细胞者24例，上皮细胞者4例； 灌洗后所有患者的收集液中均未观察到肿瘤细胞（P＜0.05），19例仍有少许中性粒细胞或上皮细胞。结论 低位直肠癌远端肠腔有可能存在脱落的肿瘤细胞。对直肠癌患者手术切除病灶后吻合前行远端肠腔灌洗的方法简单易行，可以显著减少或清除肠腔内可能残留的肿瘤细胞，从而可避免此类原因所致的局部肿瘤复发，值得提倡。
