【Abstract】ObjectiveTo discuss the molecular structures and functions of Alu repeats,and its relationships with malignant tumors. MethodsAdvances in molecular biology and oncology of Alu repeats in recent years had been reviewed. ResultsHomologous recombination between Alu repeats may result in various genetic exchanges,including duplications, deletions and translocations,cause a series of malignancy alteration by activating some oncogenes. ConclusionAlu repeats as a sort of multifunction regulatory sequences may play an important role during the carcinogenesis and progression of some tumors.
Since November 1974 to December 1993, 110 cases with malignant tumors of the extremities were treated by en bloc resection and limb salvage procedure in our hopsital. There were 57 males and 53 females. Their ages ranged from 14 to 70 years. The diagnosis of all patients were confirmed by pathology. Among them, 68 cases were malignant bone tumor, 42 cases were malignant tumor of soft tissue. If the soft tissue was involved by the malignant tumors, the tumor was resected radically and myocutaneous or skin flap was transferred to covered the defect. Among the 42 cases, 5 were free vascularized and 37 were pediculated flaps. The maximal size of the flap was 15×25 cm and the minimal was 6×8 cm. For the malignant bone tumors, en bloc resection was performed and the bone defect was reconstructed with autogenous free vascularized fibular graft, autograft of massive bone with fusion or allograft of cryogenic massive bone. If the joint was involved, limited excision with replacement of prosthesis was recommended. When both soft tissue and bone were involved, segmental resection of tumor was indicated in 17 cases. The patients were followed up for 2 to 9 years, the results of 53 cases were still alive with a survival rate of 48.2%. We emphasized that the local extensive resection should be performed with a safety margin of 3 to 5 cm beyond the tumor. A djuvant chemotheapy and radiotherapy had definite value in the treatment of some malignant tumors, so that preoperative or postoperative chemotherapy or radiotherapy was necessary. Sometimes radical resection of regional lymph rodes was necessary. The indications and causes of recurrence were discussed.
Objective To evaluate the efficacy of transposition of the medial gastracnemius muscle flap in the limbsalvage operation of the proximal tibial tumors. Methods From January 2001 to September 2005, 13 patients (8 males,5 females; aged 14-57 years, averaged 29.7 years) suffering from the proximal tibial tumors were treated with a limbsalvage operation. Among them, there were 4 patients with osteosarcoma, 6 with malignant fibrous histocytoma, 1 with malignant giant cell tumor, 1 with synovial sarcoma, and 1 with Ewing’s sarcoma. According to the Enneking staging system, 1 case was in Stage ⅠB, 9 in Stage ⅡA, and 3 in Stage ⅡB. One or two cycles of neo-adjuvant chemotherapy were used to each of the patients before operation. All of the patients underwent the medial head of the gastrocnemius muscle flap transposition to reconstruct the soft tissues after resection of the tumors and reconstruction of the bone defect by prothesis or bone-graft or the two methods combined. Results The follow-up for 7-47 months (average, 19.2 months) in all the patients revealed that. there was no flap necrosis, no skin necrosis at the incision margins, and no infection or fracture of the implanted bone. The patient with malignant fibrous histocytoma died of systemic metastasis 20 monthsafter operation. The patient with Ewing’s sarcoma had a local tumor recurrence 18 months after operation; though treated with the focal cleaning and the bone cement filling, the patient still developed lung metastasis of the tumor 26 months after operation. The patient with osteosarcoma underwent amputation 12 months after operation because of the tumor recurrence. According to the function assessment by the Mankin system, there were 6 patients who had an excellent result, 4 had a good result, and 3 had a poor result, with a satisfaction rate of 77%. Conclusion The flap transposition of the medial head of the gastrocnemius muscle can reconstruct the soft tissue defect, decrease the local complication rate and improve the clinical outcome of the limb salvage for the proximal tibia malignant tumor.
Malignant tumors are the major diseases which threat human beings. Anti-cancer medicines play important roles in the treatment of malignant tumors, especially for the new targeted therapies. They bring the life hope for cancer patients who were sentenced to death, and improve quality of life, and some patients may achieve normal lifetime. However, the new anti-cancer medicines are usually too expensive to afford, and most of them have not yet been included in Chinese public health security system, the accessibility of the new anti-cancer medicines is seriously limited. This paper introduces the accessibility of high-cost anti-cancer medicines in China, analyzes the influence factors, and proposes policy recommendations to improve the accessibility of high-cost anti-cancer medicines in China.
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.
Soft tissue expander has been improved to perfection in recent ten years. Many excellent works have been accomplished for the patients who suffered from either soft tissue malformation or defects following traumatism, infection or benign tumors. But the reconstruction of soft tissue defects cause by malignant tumor hasbeen less studied.Four patients suffering from malignant tumour localized in the scalp and face, 1women and 3 men ranging from 65 to 75 years of age, have been operated on since1986. Their major deficits have been reconstructed with radican tissue expander, by the flap of the same colour and texture and also, similar thickness and sensation. There is no relapse in all the patients operated on reported until today.The surgical technique was discribed. The clinical results and the indication of tissue expander in the surgical treatment of malignant tumour are discussed.

OBJECTIVE: To evaluate the results of limb function and the methods of bone and soft tissue reconstruction of patients treated with allografting. METHODS: From May 1992 to January 1999, 90 patients suffered from bone malignant tumor were treated with allografting in different methods of internal fixations. The average follow-up was 37.5 months. The limb postoperative function, complications related to different surgical methods were compared according to Enneking evaluation system. RESULTS: Skin necrosis, infection, non-union, fracture of allograft were the main complications which affect patients’ limb postoperative functions. Of the 90 fresh-frozen allografting procedures, the final results of operation showed that hip joints and knee joints were better than the shoulder joints. More than 80% of the patients treated with interlocked intramedullary nail and allograft-prosthesis combination led to an over-all result that was excellent and good. Interlocked intermedullary nail was of recommended method of internal fixation. Early exercises of operative limbs could promote function recovery. CONCLUSION: Using of interlocked intramedullary nail and allograft-prosthesis combination are of recommended operation method and can be applied with better results, and early exercises of operative limbs will lead to better functions.
