【Abstract】Objective To study the significance of expression of p27 in thyroid follicular tumors. Methods The tumor samples were obtained from 53 thyroid follicular tumors, and 10 normal thyroid tissues were used as a control group. p27 was detected by the immunohistochemical staining S-P method. Results The normal thyroid group had the highest expression of p27.There were significant differences in the expression of p27 between thyroid follicular adenomas (FA) and follicular carcinomas (FTC), FA had much higher expression of p27 than FTC did. There were no significant differences in the p27 staining indexes between minimally and widely invasive FTC nor between metastized and non-metastized FTC. Logistic regression showed that p27 were effective in distinguishing FA from FTC(P=0.0048). Conclusion It appears that p27 may be necessary for the malignant transformation of the thyroid follicular epithelium, which might relate to a decrease in p27. p27 detection may be helpful in distinguishing FA from FTC.
Fifteen patients with rectal carcinoid tumors were treated from 1975 to 1991. Before admision, nine patients (60%) had been misdiagnosed as polyps ,hemorrhoids or proctitis. Diagnosis may be delayed because of failure to recognize their charasteristics and by the negligeuce of doing digital examination or proctoscopy. Some aspects of the management of these tumors remain controversial. However, present-day treatment programs call for radical cancer resections only for lesions 2cm in diameter or larger, and local resections for all others. In reviewing this series of cases and other studies, we advocate that both the size of the lesion and the depth of tumor invasion should be taken as the criteria of surgical managements. If the tumor is 2cm in diameter, or smaller than that, local resection can be performed, but whenever the nuscularis propria is invaded, radical resection should be performed. Radical resection is bly indicated for tumors larger than 2cm.
Objective To summarize the diagnosis and treatment of synchronous multiple primary malignant tumors in lung. Methods The clinical and pathological data of 5 cases with intrapulmonary synchronous multiple primary cancer, who were diagnosed in recent 10 years in Xinhua Hospital, were retrospectively analyzed. Results The incidence of intrapulmonary synchronous multiple primary cancer was 0. 21%( 5 /2380) in all lung cancer cases diagnosed in respiratory department of Xinhua Hospital. There were 4 males and 1 female, with the average age of 60. 2 years old. Five patients were all treated with surgical operation. Four patients with bilateral synchronous multiple primary lung cancer underwent staging operation treatment( larger lesions on one side of lung underwent conventional thoraceotomy and lobectomy, and smaller lesions on another side underwent thoracoscopic lobectomy or wedge resection afer 1 month) . For 1 patients with ipsilateral synchronous multiple primary lung cancer, simultaneous operation was performed. There was no death during perioperative period or severe cardiopulmonary complications. They were followed up for 3 years. The survival rate was 80. 0%( 4 /5) at 1 year and 60. 0% ( 3/5) at 3 years, respectively. Conclusions With the development of medical science and awareness of pulmonary multiple primary cancer, early diagnosis improves continuously. Active treatment with operation can achieve better prognosis.
Objective To investigate the diagnosis and treatment methods of primary cardiac malignant tumors，so as to improve its’ level of diagnosis and treatment. Methods From April 2004 to June 2008, 19 patients with primary cardiac malignant tumors were diagnosed and treated in the department of cardiac surgery in this hospital. Male 11, Female 8.Age of the patients was 40.7±12.1 years(17-64 years). Preoperative diagnosis were occupying lesion in cardiac, malignant tumors were possible. Complete resections of malignant tumors were achieved by cardiopulmonary bypass (CPB) in 3 cases, and partially resected in 1 case, heart transplantation was performed in 1 case, only biopsies were performed in 5 cases. 9 cases (47.4%) lost the chances of operative treatments. Results There were no operative and hospitalstay deaths. Hospital stay was 10±7 d（9-15 d）, all patients were safely discharged from hospital. Two cases suffered from postoperative pericardial effusions，and high temperature happened in 1 patient, these 3 cases recovered by puncture and symptomatic treatment. The pathological diagnosis: leiomyosarcoma in 1case, malignant mesothelioma in 1 case and hemangioendothelial sarcoma in 8 cases. 14 cases (73.7%) were followed up from 1 to 38 months, 14 cases died of tumor recurrence or metastasis, the mortality was 73.7%, 5 cases (26.3%) were failed to be followed up. Conclusion The prognosis of patient with primary cardiac malignant tumor is still poor. Earlier diagnosis and complete surgical removal of the tumor as soon as possible may improve the patients’qualities of lives.
Objective To elucidate the surgical indicationsand treatment outcome of total spondylectomy and reconstruction for thoracolumbar spinal tumors with neurological deficit. Methods From January 1999 to December 2005, 16 patients with thoracolumbar spinal tumors with neurological deficit were treated with total spondylectomy and reconstruction. There were 10 males and 6 females, with an average age of 31.5 years(16-62 years).There were 10 cases of primary tumors of spine (4 giant cell tumor of bone, 3 chondrosarcoma, 2 recurrent aneurysmal bone cyst, and 1 osteosarcoma), and 6 cases of solitary metastasis of thoracic or lumbar spine. Tomita’s surgical classification was as follows: 9 cases of type 4, 6 of type 5, and 1 of type 6. Frankel’s neurological classification was as follows: grade A in 1 case, B in 4, C in 7,and D in 4. All patients were treated with total spondylectomy and reconstruction through combined anterior and posterior approach. Results All patients were followed up from 10 to 63 months with an average of 27.5 months. Pain was relieved completely in all patients. The neurological function returned to grade D in 5 cases, to grade E in 11 cases. Among the 10 patients with primary spinal tumor, nine patients survived with tumor-free, and one with osteosarcoma died because of lung metastases 18 months after surgery. Among the 6 patients with spinal metastasis, three patients survived with tumorfree, and lung metastasis occurred in 1 case 10 months after surgery, two died because of multiple metastases of internal organs 10 months and 32 months after surgery. Conlusion Total spondylectomy and reconstruction is a safe and effective surgery for thoracolumbar spinal tumors with neurological deficit, with pain relief, neurological improvement and minimum tumor recurrence. It will be an optimal choice for patients with primary malignant, aggressive benign, or solitary metastatic bone tumors of the thoracolumbar spine with Tomita surgical classification type 3 to 5.
Objective To probe a satisfactory surgical management of the limbsalvage for osteogenic malignant tumors around the knees. Methods From January1989 to December 2001, 42 patients (19 males and 18 females, aged 12-46) with osteogenic malignant tumors around the knees underwent surgical management of the limb salvage, including prosthesis replacement, allogenous bone grafting, and bone cement with adriamycin filled. Based on the pathological examination, osteosarcoma was found in 11 patients, synoviosarcoma in 4 patients, malignant fibrous histiocytoma in 3 patients, and giant cell tumor of the bone in 19 patients. All the patients underwent neoadjuvant chemotherapy for 1-2 courses before operatioexcept the patients with giant cell tumor of the bone. The patients underwent prosthesis replacement, allogenous bone grafting, bone cement with adriamycin filled, and postoperative chemotherapy. By the Enneking evaluating system, the patients were assessed on their reconstructed limb functions after the reconstructive operation for the musculoskeleta malignant tumors. Of the patients, 37 were followed up after operation. Results According to the follow-up for 3-11 years (mean, 5.6 years) in the 37 patients, 2 patients had recurrence and metastasis of the tumor, and died 3 and 4 years after operation, respectively. One patient underwent amputation of the limb for local recurrence of the tumor. One patient had amputation of the limb for the preoperative radiotherapy and the infection and necrosis of the operative wound after the limb-salvage surgery. Two patients had amputation of the limb for the rejection of the allogenous bone graft and theformation of the fistula.Thirty-one patients had good wound healing andgood functions of the limb. The results were evaluated by the Enneking evaluating system as follows: excellent in 7 patients, good in 14, fair in 10, and poor in 6. Conclusion Making an early diagnosis, recognizing the operative indication, choosing the operative method, and performing the preoperative and postoperative chemotherapy and/or radiotherapy are the keys to achieving an ideal limb-salvage surgery for osteogenic malignant tumors around the knees.
Objective The efficacy and morbidity of thoracoabdominal incision in comparison with flank incision for radical nephrectomy are unknown. This retrospective study was performed to compare the outcome of thoracoabdominal incision versus flank incision for radical nephrectomy in patients with large renal tumors. Methods A questionnaire assessing the time of postoperative pain, use of anodyne and return to daily activities and work was sent to patients who underwent radical nephrectomy through the 11th rib (flank incision, group A, 96 patients) or the 9th to 10th rib (thoracoabdominal incision, group B, 98 patients) from 2003 to 2008 at the Second Xiangya Hospital in Changsha, China. A case retrospective analysis assessing operation time, perioperative hemorrhage volume, size of tumors, success in the treatment of tumor thrombus in renal vein or vena cava, presence of drainage-tube, postoperative analgesia usage and length of stay was done for patients whose questionnaires were returned. Results The length of operation time and the presence of abdominal drainage-tube was shorter in the thoracoabdominal incision group (group B) than in the flank incision group (group A). The perioperative hemorrhage volume in group B was less than that in group A. The mean size of tumors in group A was smaller than that in group B (Plt;0.000 5). The success rate in the treatment of thrombus in renal vein or vena cava in group B was higher than that in group A (Plt;0.05). The length of off-bed time and of hospital stay were similar in both groups. There were no significant differences between the groups in pain severity postoperative day 1, on the day of discharge and 1 month postoperatively (Pgt;0.05). There were no significant differences between the groups in the time from surgery to the complete disappearence of pain, to the discontinuation of pain medication, and to the return to daily activities and work (Pgt;0.05). Conclusion The approach of thoracoabdominal incision provides better exposure. Morbidity is comparable for thoracoabdominal and flank incisions in terms of incisional pain, analgesic requirements after discharge and return to normal activities.
