摘要

目的:以強度調控放射線治療(IMRT)合併化學治療於惡性間皮細胞瘤之治療效果評估。
材料與方法:此為一位65歲男性、右側肋膜腔內有惡性間皮細胞瘤之病患,其主訴為咳嗽帶有血絲已有3個月、呼吸短促、體重減輕。此病患之胸腔X光片中發現右側肋膜積水,初判為肺癌。於2003年1月3日安排胸部電腦斷層掃瞄(CT scan),發現右下肺門有腫塊及肺腫脹不全。最後根據CT影像,判為肺腫脹不全之右下側支氣管肺癌,並且右側肺積水。施予肺積水引流後,再做一次胸部X光,發現肺肋膜增厚。於2003年1月17日,施予病理切片,報告指出為上皮型之惡性間皮細胞瘤,CEA染色呈陰性,而CK和EMA染色則呈陽性。TNM期別為T2N1M0。隨即安排病患進行放射線治療。經GE lightspeed電腦斷層機,取得切片厚度為5公厘之放射線治療用的定位CT影像,治療計畫系統為Eclipse第六版。IMRT治療部位為右側整個肺肋膜,總劑量為64.6格雷,自2003年2月12日至4月22日,為期61天,共38次。放射治療4天前,病患先接受了的cisplatin 100毫克經靜脈之化學治療。
結果:之後,病患在門診追蹤持續了幾個月。射線線治療後六個月內,都沒有復發。追蹤之CT影像中顯出,輕微肺積水及右側肺肋膜腔逐漸變小。於2003年10月發現腦轉移,2003年10月18日至2003年11月20日,給予姑息性之全腦放射線治療,總劑量為42.5格雷。該病患於2003年11月30日死亡。
結論:惡性間皮細胞瘤在無法進行根除性開刀手術(EPP)之餘,強度調控放射治療亦為一個選擇,並且沒有發生因高劑量的放射線而誘發的肺炎。此外,須要更多的臨床試驗去評估這新的治療方法之效益。

This 65-year-old male patient had an initial complaint of persistent cough with blood-tinged sputum for 3 months, and associated symptoms were progressive shortness of breath and body weight loss. Because the patient's chest x-ray revealed right pleural effusion, the initial impression was lung cancer. A chest CT scan was performed and revealed a right infrahilar mass with atelectasis of the right lower lung, and a small nodular density in the right upper anterior lung segment. The final diagnosis of the CT scan was lung cancer of the right lower bronchus with atelectasis and right pleural effusion. A repeat chest PA after pleural fluid drainage revealed thickening of the right visceral and parietal pleurae. A thoracotomy with a pleural biopsy was performed 2 weeks after the CT scan. The pathology revealed an epithelial-type well-differentiated malignant mesothelioma; CK and EMA stains were positive, while CEA stain was negative. The TNM staging was T2N1M0. Radiotherapy was then arranged for this patient. A CT scan of the entire chest cavity in 5-mm slices was performed prior to radiotherapy for treatment simulation with a GE lightspeed scanner. Radiotherapy treatment planning was done with the Eclipse RTP system, version 6.5. Intensitymodulated radiotherapy (IMRT) was given to the entire right visceral and parietal pleurae for a total dose of 64.6Gy in 38 fractions over a 61-day period from Febuary 12 to April 22, 2003. The patient also received a course of chemotherapy with 100 mg cisplatin iv given 4 days before the start of radiotherapy.Results: The patient, who was followed-up in the outpatient clinic every month, had suffered no local recurrence by 6 months after radiotherapy, and a follow-up CT scan showed slight pleural effusion with progressive regression of the right pleural cavity. The patient suffered a brain metastasis in October 2003. Palliative radiotherapy for the entire brain was given from October 18 to November 20, 2003 for a total dose of 42.5Gy. The patient unexpectedly expired on November 30, 2003.Conclusions: IMRT is an alternative treatment option for a malignant mesothelioma which is otherwise unsuitable for a radical extrapleural pneumonectomy (EPP). No severe radiation-induced pneumonitis was noted even with the high dose of IMRT. More clinical trials are needed to determine the benefit of this new treatment modality.",
