Here reported a case of 62-year-old man with concomitant three early stage cancer lesions in upper gastrointestinal tract, all of which were detected by endoscopy. The first one was an llc-type lesion at angular part of stomach under endoscopy, which was histologically confirmed to be a mucosal well-differentiated adenocarcinoma.The patient underwent a standard radical gastrectomy for the lesion after the failure of endoscopic treatment. The other two neoplasms were observed during follow-up and were indicated as early stage lesions by synthesizing information from endoscopy, endoscopic ultrasonography, computed tomography and biopsy. One displayed as a hyperemic patch （3cm×4 cm in size） located at the part of esophagus 27 cm away from the incisor teeth and was proved to be moderately differentiated squamous cancer by histopathological examination. The other was an llc-type lesion （3.0 cm×3.5 cm in size） located at the part of esophagus 36 cm away from the incisor teeth, and the biopsy result showed a poorly differentiated squamous carcinoma. Both the two lesions were treated with radical radiation because the patient refused surgery management. No recurrence of former lesions or occurrence of novel lesions were observed during post-treatment follow-up, suggesting radical radiation might be effective for this patient.展开更多

Aim: To reflect on the challenges of a case with multiple integrated diagnostic and therapeutic approaches and to bring to consideration the increasing prevalence of similar situations. Case Presentation: In this clinical case, the authors describe the evolution of an asymptomatic patient with several synchronous tumours (a GEJ primary adenocarcinoma, a low grade urothelial carcinoma in situ, a localized squamous cell lung carcinoma and 2 IPMNs). Conclusion: The challenge of this case lies in the difficult diagnostic approach, the assembly of a multidisciplinary and time-sensitive treatment plan and the individualized follow-up, due to lack of guidelines. More research is needed in this area.展开更多

The incidence of lung cancer in cases of colorectal cancer is rare and synchronous rectal cancer and lung cancer is even rare. A 61-year-old man was referred to our hospital with a 2-month history of blood in his stool, tenesmus, and mucous discharge in July 2010. Colonoscopy showed an irregular ulcerated rectal mass and histological examination of biopsy material showed a poorly differentiated adenocarcinoma. Computed tomography （CT） scan of the chest and abdomen showed a mass in the posterior segment of the right upper lobe of the lung and a mass in the right rectal wall of upper rectum. The rectal tumor was diagnosed as primary cancer based on the findings of immunohistochemical stain. An anterior resection （AR） and video assisted thoracoscopic （VAT） wedge resection were performed and histological findings of resected rectal and lung tumor specimen showed synchronous primary rectal cancer and lung cancer. A combination chemotherapy regimen with docetaxel and Iobaplatin was used and the patient was successfully discharged from hospital in August 2010. Although the incidence of synchronous multiple primary cancers is very low, we need to remain suspicious, when faced with two or even multiple organ lesions, and employ the necessary examination methods to confirm the diagnosis. For synchronous multiple primary cancers, if conditions allow, surgical resection for all the cancers can be performed in a single operation.展开更多

文摘背景与目的肺内多发小结节微创手术的成功与否有赖于术前定位,然而目前缺乏针对肺内多发小结节术前定位的临床研究。本研究旨在与同期肺内单发小结节定位相比,探讨行电视胸腔镜手术(video-assisted thoracoscopic surgery, VATS)术前电子计算机断层扫描(computed tomography, CT)引导下留置微弹簧圈定位肺内多发小结节的临床价值。方法回顾性分析术前行肺内小结节微弹簧圈定位者235例的临床资料。根据结节是否为单发分为:单发结节组184例(single nodule group),多发结节组51例(multiple nodules group)。单发结节组常规方式CT引导下定位,多发结节组在CT引导下分级、分批次留置微弹簧圈定位,统计分析两组定位成功率、并发症、病理结果及定位操作相关数据等。结果多发结节组定位成功率达90.2%,与同期单发结节组成功率相比无统计学差异(90.2%vs 94.6%,P=0.205),多发结节组气胸发生率与单发结节组亦无统计学差异(21.6%vs 14.1%, P=0.179),然而多发结节组的操作时间明显长于单发结节组的操作时间[(30.6±6.6) min vs (19.9±7.4) min, P=0.000]。两组均无大咯血、空气栓塞及血胸发生等严重并发症。两组均无因术中无法定位结节而中转开胸者;手术方式以亚肺叶切除为主;术后病理以非浸润性病变为主。结论对于需行胸腔镜手术的肺部多发小结节,按照一定策略,术前CT引导下分级、分批次留置微弹簧圈的定位方法安全、有效,值得推广。
