  • THE SIGNIFICANCE OF CYCLIN D1 AND P53 PROTEIN EXPRESSION IN BREAST CARCINOMA AND FIBROSARCOMA INDUCED BY DMBA IN RATS

    【Abstract】Objective To investigate the significance of cyclin D1 and p53 protein expression in synchronous breast carcinoma and fibrosarcoma in rats. Methods Immunohistochemical SP methods was used to study the expression of cyclin D1 and p53 in synchronous breast carcinoma and fibrosarcoma induced by DMBA in rats.Results There was no expression of cyclin D1 and p53 in normal breast tissue. In atypical hyperplasia of mammary, there was overexpression of cyclin D1(7/14) and no expression of p53. The overexpression of cyclin D1 and p53 were detected in breast carcinoma (8/18,7/18 respectively) and fibrosarcoma (9/14,5/14 respectively). There was no expression of cyclin D1 and p53 in adjacent sarcoma.The expression of cyclin D1 and p53 protein was associated with histological grading, and showed inverse relation between them. Conclusion There are cyclin D1 and p53 protein overexpression in the synchronous breast carcinoma and fibrosarcoma induced by DMBA in rats. Cyclin D1 may paticipate in the course of the carcinogenesis of breast carcinoma and fibrosarcoma in rats, and p53 protein overexpression may relate to the degree of malignancy of the tumors.

  • ASSOCIATION BETWEEN SINGLE NUCLEOTIDE POLYMORPHISMS OF V-MAF MUSCULOAPONEUROTIC FIBROSARCOMA ONCOGENE HOMOLOG B GENE AND NON-SYNDROMIC CLEFT LIP WITH OR WITHOUT CLEFT PALATE

    Objective To reveal the association between the single nucleotide polymorphism (SNP) of v-maf musculoaponeurotic fibrosarcoma oncogene homolog B (MAFB) gene rs17820943 locus and non-syndromic cleft l ip with or without cleft palate (NSCL/P) in the southern Chinese Han population. Methods Genotyping of MAFB gene rs17820943 polymorphism was carried out in 300 patients with NSCL/P, 354 normal controls, and an additional 168 case-parent trios with matrix-assisted laser desorption/ionisation time-of-fl ight (MALDI-TOF) mass spectrometry. Then based on the genotypingresults, both a case-control association study and a case-parent trio association study were performed. Results Significant differences were found in the allele and genotype frequencies of rs17820943 locus between case and control groups (Pallele=0.001 and Pgenotype=0.002, respectively). To be specific, the odds radio (OR) values and 95% confidence interval (95%CI) of allele T (frequencies of cases ∶ controls = 0.358 ∶ 0.448) and genotype TT (frequencies of cases ∶ controls = 0.110 ∶ 0.195) were ORT = 0.69 (95%CI: 0.55-0.86) and ORTT = 0.43 (95%CI: 0.26-0.70), respectively. Subsequent case-parent trio analysis also indicated an association between MAFB rs17820943 variant and the risk of NSCL/P (ORT vs. C = 0.55, 95%CI: 0.41-0.75, P value of transmission disequilibrium test was 0.000). Conclusion Polymorphism of MAFB gene rs17820943 locus is associated with NSCL/P in the southern Chinese Han population; MAFB rs17820943 variant may be a susceptible gene of NSCL/P.

  • SURGICAL TREATMENT OF DERMATOFIBROSARCOMA PROTUBERANS USING WIDE LOCAL EXCISION COMBINED WITH Mohs MICROGRAPHIC SURGERY

    Objective To investigate the method and effectiveness of wide local excision combined with Mohs micrographic surgery for dermatofibrosarcoma protuberans (DFSP). Methods Between January 2007 and January 2010, 17 patients with DFSP were treated. There were 9 males and 8 females with an average age of 33.2 years (range, 16-55 years). Thelesions were located at head and neck (2 cases), trunk (12 cases), extremity (2 cases), and perineal region (1 case). There were 6 cases of primary DFSP and 11 cases of relapsed DFSP. The lesions presented as single or multitude nodules or fusion nodules with skin withering, scar, en plaque in the center and with ill-defined margins. The diameter of lesions ranged from 0.8 to 9.7 cm (mean, 4.3 cm). No distant metastasis or lymphatic metastasis occurred in all cases. After tumors resection by wide local excision combined with Mohs micrographic surgery, the wounds were repaired by direct suture in 3 patients, skin grafting in 9 patients, and local skin flap in 5 patients. Results Wide local excision and Mohs micrographic surgery were carried out once in 13 patients, twice in 3 patients, and three times in 1 patient with an average operation time of 98.6 minutes (range, 56-219 minutes). Primary heal ing of wound and donor site were achieved with no necrosis of skin grafting and skin flap. All patients were followed up 8-34 months (mean, 21.7 months) with no recurrence. Conclusion Wide local excision combined with Mohs micrographic surgery could treat DFSP, which has the advantages of shorter operation time, radical resection, and less injury.

  • Clinicopathological Analysis on Sclerosing Epithelioid Fibrosarcoma

    目的 探讨硬化性上皮样纤维肉瘤(SEF)的临床病理学特征。 方法 对2012年3月收治的l例SEF患者进行组织学观察、免疫组织化学检查并复习相关文献。 结果 SEF主要以细胞质透亮的上皮样肿瘤细胞伴大量透明变性胶原纤维为特征,瘤细胞排列主要呈条索状、巢状。肿瘤细胞波形蛋白阳性表达,细胞角蛋白和平滑肌肌动蛋白阴性表达。 结论 SEF是一种较为罕见的软组织肿瘤,应注意与一些具有上皮样形态和硬化性间质的肿瘤相鉴别。

  • 乳腺隆突性皮肤纤维肉瘤2例临床报道

    目的探讨乳腺隆突性皮肤纤维肉瘤(DFSP)的临床特征、诊断及治疗方法。 方法回顾性分析我院近期收治的2例乳腺DFSP患者的临床资料。 结果本组2例分别为一27岁男性与一35岁女性患者。男性DFSP患者出现典型的皮肤紫红色改变并突出皮肤表面,一直被诊断为“血管瘤”;乳腺彩超示肿块边界欠清,形态不规则,以低回声为主,周边见环形强回声带,彩色多普勒血流成像见其内短线状血流信号,术前肿块30 mm×11 mm大小。女性DFSP患者则长期被误诊为乳腺纤维腺瘤;乳腺钼靶仅提示双乳乳腺增生,未见确切肿块组织,术前肿块5 mm×10 mm大小。2例患者均采用传统手术治疗模式,肿瘤细胞均高表达CD34,低表达S-100及细胞角蛋白。分别随访8个月与4个月,术后未常规行放疗,至目前未复发。 结论乳腺DFSP是起源于乳腺皮肤区域并可浸润皮下组织的局限性低度恶性肿瘤,以无痛性肿块为主要临床表现,术前各种影像学检查诊断特异性欠佳,确诊有赖于肿块切除术后的组织学病理检测及免疫组织化学分析。彻底的手术切除疗效理想,部分切缘阳性或局部复发的患者可能需进一步综合放疗或伊马替尼靶向治疗。
