  • Carcinosarcoma of gallbladder is a rare malignant tumor characterized by malignant epithelial and malignant mesenchymal components. Its pathogenesis is unknown and most of carcinosarcomas of gallbladder are associated with poor survival because the disease presents at an advanced stage. A 69-year-old man presented with right upper quadrant pain. The preoperative diagnosis was gallbladder cancer, and thus, curative radical cholecystectomy was performed. Pathologic examination of the surgical specimen revealed that the tumor was composed of carcinomatous components with adenocarcinoma and squamous cell carcinoma, and sarcomatous components with spindle cell sarcoma and chondrosarcoma, which was consistent with a diagnosis of primary carcinosarcoma of the gallbladder. The tumor was found to extend to the pericholecystic fat and no metastasis in regional lymph nodes.

  • Carcinsarcoma is an uncommon pulmonary malignancy characterized by carcinmatous parenchyma and sarcomatous stroma. The cytologic, immunohistochemical and ultrastructural features of a case of pulmonary carcinosarcoma suspected by fine needle aspiration cytology is presented. Only bizarre spindle cells arranged in loose groups, in microtissue fragments and in a dissociate fashion were present on the aspiration smears. They were markedly positive for vimentin. The epithelial component was not found, which was probably due to marked paucity of carcinomatous component that was proved by histologic examination of the resected tumor. The diagnosis of pulmonary carcinosarcoma should be conidered whenever poorly differentiated epithelial ceil groups with a malignant mesenchymal component set in a myxoid background are seen in a pulmonary cytology specimen.

  • Carcinosarcoma of the parotid gland is extremely uncommon and is known to be an aggressive malignant mixed tumor in which carcinomatous and sarcomatous elements coexist and metastasize together. We report a case of recurrent parotid gland carcinosarcoma that showed squamous cell carcinoma and chondrosarcoma in a 58-year-old woman.

  • Purpose: Carcinosarcomas are rare neoplasms in which both malignant epithelial and mesenchymal elements are identified. We have found only twenty one cases of primary cutaneous carcinosarcoma in the English language literature. Therefore it has been difficult to diagnosis because its unclear etiology and low frequency. Methods: A 31-year-old young man with a protruding mass on his ankle dorsum was examined. The tumor was $7{\times}6{\times}3\;cm$ sized and arose from a burn scar. The mass was wide excised and applied split thickness skin graft. Characteristic pathologic finding was a mixture of squamous cell carcinoma and malignant fibrous histiocytoma. Results: Three months after the operation, the patient died of multiple metastasis to the liver, lung and finally of sepsis despite adjuvant chemotherapy and adjuvant radiotherapy. Conclusion: If a metastatic cutaneous carcinosarcoma is diagnosed, wide excision is required. There should be more aggressive management to minimize the risk of recurrence. Further research into the etiology and pathophysiology of the disease and a more careful differential diagnosis may allow improvement in treatment.

  • Purpose: We designed this study to identify and suggest the reasonable timing of adjuvant radiotherapy in the treatment of uterine carcinosarcoma according to the surgical intent and patterns of progression. Materials and Methods: We retrospectively analyzed a total of 50 carcinosarcoma patients diagnosed between 1995 and 2010. Among these 50 patients, 32 underwent curative surgery and 13 underwent maximal tumor debulking surgery. The remaining five patients underwent biopsy only. Twenty-six patients received chemotherapy, and 15 patients received adjuvant radiotherapy. Results: The median follow-up period was 17.3 months. Curative resection (p < 0.001) and stage (p < 0.001) were statistically significant factors affecting survival. During follow-up, 30 patients showed progression. Among these, eight patients (16.0%) had loco-regional progression only. The patients who had received adjuvant radiotherapy did not show loco-regional progression, and radiotherapy was a significant negative risk factor for loco-regional progression (p = 0.01). The time to loco-regional progression was much earlier for non-curative than curative resection (range, 0.7 to 7.6 months vs. 7.5 to 39.0 months). Conclusion: Adjuvant radiotherapy in the treatment of carcinosarcoma might be related to a low loco-regional progression rate. Radiotherapy should be considered in non-curatively resected patients as soon as possible.

  • 폐의 암육종은 상피조직과 간염조직이 혼재하는 악성종양으로 전체 폐종양의 0.3%에 불과한 매우 희귀한 종양이며 흡연과 깊은 관계가 있는 질환이다. 폐에서의 위치에 따라 비교적 예후가 양호한 endobronchial type과 빠른 원격전이로 예후가 불량한 solid parenchymal type으로 분류된다. 비침습적 진단방법으론 발견이 어렵고 생검에 의해 종종 발견된다. 폐문과 종격동으로 전이를 잘하며 광범위 절제가 치료의 기본이고 항암제 요법을 병용하기도 한다. 암육종의 예후는 매우 불랑하여 술후 평균생존 기간은 9개월 정도이고 2년까지 생존율은 10% 미만인것으로 보고 된다.

  • Purpose: To evaluate the impact of postoperative radiotherapy (PORT) on patterns of failure and survivals in uterine carcinosarcoma patients treated with radical surgery. Materials and Methods: Between October 1998 and August 2010, 19 patients with stage I-III uterine carcinosarcoma received curative hysterectomy and bilateral salpingo-oophorectomy with or without PORT at Seoul National University Hospital. Their hospital medical records were retrospectively reviewed. PORT and non-PORT groups included 11 and 8 patients, respectively. They were followed for a mean of 22.7 months (range, 7.8 to 126.6 months). Results: At 5 years, the overall survival rates were 51.9% for entire, 61.4% for PORT, and 41.7% for non-PORT groups, respectively. There was no statistical difference between PORT and non-PORT groups with regard to overall survival (p = 0.682). Seven out of 19 (36.8%) patients showed treatment failures, which all happened within 12 months. Although the predominant failures were distant metastasis in PORT group and loco-regional recurrence in non-PORT group, there was no statistically significant difference in locoregional recurrence-free survival (LRRFS) (p = 0.362) or distant metastasis-free survival (DMFS) (p = 0.548). Lymph node metastasis was found to be a significant prognostic factor in predicting poor LRRFS (p = 0.013) and DMFS (p = 0.021), while the International Federation Gynecology and Obstetrics (FIGO) stage (p = 0.043) was associated with LRRFS. Conclusion: Considering that adjuvant radiotherapy after surgical resection was effective to decrease loco-regional recurrence and most treatment failures were distant metastasis, multimodal therapy including surgery, radiotherapy, and chemotherapy might be an optimal treatment for uterine carcinosarcoma patients.
