We report a case of a long-term survivor with malignant melanoma of the anus who did not undergo radical surgery. A 71-year-old
woman who presented with anal bleeding and anal tumor underwent an excisional biopsy in September 1985. The biopsy specimen
was a lobulated, polypoid, pigmented mass 2 cm in diameter, that had been located on the anterior wall of the anus. A satellite
nodule 7 mm in diameter was found on the left wall of the anus at the level of the dentate line. Both tumors were histologically
diagnosed as malignant melanoma. The primary tumor was 6 mm thick. Melanoma cells were present microscopically at the cut
end of the rectum. Because of her history of ischemic heart disease, the patient rejected our recommendation that she undergo
radical surgery, and received 10 courses of carboplatin 20 mg intramuscularly and OK-432 10 K.E. (Klinische Einheit) intradermally
every week. A single, pigmented metastatic inguinal lymph node developed and was excised in June 1987. A recurrent tumor was
detected in the rectum in October 1992, so again we recommended radical surgery. The patient rejected radical surgery again,
and received 12 courses of carboplatin 10 mg intramuscularly every 2 weeks. She died of disease at home in July 1993 after
surviving for 7 years and 10 months. An autopsy was not performed. This case shows that local excision of the primary lesion
may be appropriate to preserve the quality of life of patients with early-stage malignant melanoma of the anus. 相似文献

Objective: To study the pattern of lymphnode metastasis in carcinoma of esophagus. Methods: 200 cases of resected esophageal
cancer specimens were carefully examined pathologically. Lymphnode metastasis, its pathway and extent in relation to pathological
changes were analyzed. Results: Lymphnode metastasis was mainly regional and extended vertically in both directions. Leaping-over
metastasis was another feature. The deeper invasion by the tumor, the higher frequencies of metastasis development, and vice
versa. However, leaping-over metastasis was more likely to occur where tumor invasion was less severe. Conclusion: Owing to
the high frequency of lymphnode metastasis in the superior mediastinum and the widely spanned leaping-over metastasis, an
operative approach by three incisions through right thoracotomy with excision of the whole segment of esophagus and anastomosis
at cervical region was recommended, in order to dissect lymphnodes in the cervical, thoracic and abdominal regions and to
leave less or no metastatic lymphnodes behind. 相似文献

Frequency of pancreatitis after endoscopic retrograde cholangiopancreatography with iopromid or iotrolan: a randomized trial 总被引:1,自引:0,他引:1
Blood isotone contrast media is considered to be less toxic to vascular and pancreatic duct endothelium than high-osmolar
contrast media. In this study we assessed the impact of a low-osmolar contrast agent compared with a blood isotone product
on pancreatic damage induced by endoscopic retrograde cholangiopancreatography (ERCP) and endoscopic retrograde sphincterotomy
(EST). In a prospective trial 42 consecutive ERCP/EST patients were randomized to receive either iopromid, a low-osmolar non-ionic
contrast agent (770 mosmol/kg H2O), or iotrolan, a blood-isotone non-ionic product (320 mosmol/kg H2O). The endoscopies were performed by two experienced endoscopists. Forty patients were included in the study. Blood samples
were collected before and 40 min, 2, 4, 6 and 24 h after the endoscopic procedure. Samples were analysed for pancreatic serum
enzymes, acute-phase proteins and blood counts. A clinical pain score was investigated. Post-ERCP pancreatitis was diagnosed
in 2 patients in the iopromid group and in 5 patients in the iotrolan group. There was no significant difference between groups
in the time course of pancreatic serum enzymes, acute-phase proteins or in the pain score. Due to the small number of patients
in this study, only stronger differences caused by the two contrast media could have led to statistically significant results.
We did not observe statistically significant differences in comparing iotrolan and iopromid concerning ERCP/EST-induced pancreatic
damage.

We report a favorable outcome following a staged radical excision of an intramedullary low-grade astrocytoma involving the entire spinal cord in a pediatric patient. Although the preoperative neurological status was poor, the eventual outcome was good. This highlights the importance of a good tumor-cord interface that permitted a radical excision of an extensive tumor. Since partial excision followed by radiotherapy usually results in disease progression in patients with low-grade astrocytomas, radical excision and follow-up is probably the treatment of choice. 相似文献

目的 对比分析宫颈上皮内瘤变(CIN)阴道镜下活检与电环切除术后病理,提高CIN诊断的准确性。方法 回顾性对比分析216例宫颈上皮内瘤变阴道镜下活检与电环切除术后病理,探讨影响两者符合率的相关因素。结果 两者对比,宫颈电环切除术(LEEP)后病理结果与阴道镜下活检相符的74例,升级的18例,降级的124例。阴道镜下检查不满意者活检与电环切除术后病理对比,升级率大于阴道镜下检查满意者,差异有显著性(P〈0.01)。结论 宫颈转化区向宫颈管上移者,要注意宫颈管内的病变。宫颈电环切除术可以部分弥补阴道镜下活检的缺陷,且有治疗作用。 相似文献

乳腺癌手术保留肋间臂神经的临床价值 总被引:1,自引:0,他引:1
目的探讨乳腺癌手术腋窝淋巴结清扫时保留肋间臂神经的临床价值。方法84例Ⅰ、Ⅱ、Ⅲa期乳腺癌患者,随机分为两组,试验组(36例)拟行乳腺癌腋窝淋巴结清扫术时保留肋间臂神经,对照组(48例)拟行常规手术切除肋间臂神经。术后对两组患者进行观察并随访。结果试验组术后发生上肢感觉障碍7例(19.4%),而对照组有35例(72.9%),二者比较差异有统计学意义(χ2=23.53,P<0.005);经3~48个月随访均未发现局部复发。结论Ⅰ、Ⅱ、Ⅲa期乳腺癌行腋窝淋巴结清扫术时保留肋间臂神经可以明显减少术后患侧上肢感觉障碍的发生,提高生存质量。 相似文献

AIMS: The objectives of this study were to compare the efficacy of dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) in assessing the response of primary breast carcinoma to neoadjuvant chemotherapy compared to conventional imaging modalities, and to see how surgical outcome was influenced as a result of these findings. METHODS: Thirty-four patients with locally advanced primary breast cancer underwent conventional imaging and DCE-MRI following six cycles of neoadjuvant chemotherapy prior to surgery. Changes in surgical management based on the post-chemotherapy DCE-MRI findings were recorded. RESULTS: Prior to neoadjuvant chemotherapy, 22 of the 34 patients were assessed as requiring mastectomy and the remaining 12 were considered inoperable. Following chemotherapy two patients were still considered inoperable. In 11 of the 34 patients, the final decision to proceed to either mastectomy or non-surgical management was based primarily on pre-treatment disease status or patient choice. DCE-MRI findings, therefore, contributed to the operative decision in 21 of 34 patients. Two of these 21 patients were spared surgery as DCE-MRI demonstrated complete response to chemotherapy and one declined surgery. The remaining 18 were able to undergo wide local excision, with only two patients subsequently requiring mastectomy for involved margins. CONCLUSIONS: DCE-MRI is able to accurately predict those patients suitable for breast conserving surgery following neoadjuvant chemotherapy and should be the imaging modality of choice in assessing the response of patients with primary breast carcinoma to neoadjuvant chemotherapy. 相似文献
