Spontaneous pneumothorax accompanying primary lung cancer is rare and its occurrence as an initial sign of primary lung cancer is much rarer. A few articles on spontaneous pneumothorax accompanying lung cancer have been published in Korea so far. Lung cancers, diagnosed after spontaneous pneumothorax, are usually in advanced stage, so that conservative treatment modalities such as closed tube thoracostomy, chemotherapy, or radiotherapy are the mainstream of the treatment. We experienced a case of local recurrence of primary lung cancer in six months after radical resection and radiotherapy of neoplasm performed immediately after the diagnosis by excisional biopsy of bulla, for which resection and pleurodesis had been done under the impression of spontaneous pneumothorax. In this paper, we report the case and follow-up observation of the patient.

Thirty-four patients were received bidirectional cavopulmonary shunt[BCPS] from Aug. 1989 to Apr. 1991 at Sejong General Hospital, Puchon, Korea. Their ages were from 43 days to 21 years old with 19 cases of infant, 10 from 1 to 5 years old and 5 cases above 6 years old. Their diagnoses were as follows: 13 cases with uni-ventricular heart, 9 tricuspid atresia, 6 double outlet of right ventricle, 4 pulmonary atresia with intact ventricular septum, and 2 transposition of great arteries with pulmonary stenosis. Among them, 10 patients had received other palliative operations before. The BCPS operations were performed under the cardiopulmonary bypass and 10 patients who had bilateral superior vena cava received bilateral BCPS. Other associated procedures were 9 cases of takedown of Blalock-Taussig shunt, 3 pulmonary artery angioplasty, 1 unifocalization, 1 repair of total anomalous pulmonary venous return, 1 Damus procedure, 1 relief of sub-aortic stenosis, 1 right ventricular outflow tract reconstruction and one case of tricuspid valve obliteration. There were 3 operative deaths[8.8%] and two late deaths. The remainders show good postoperative state and their oxygen saturation was increased significantly. Conclusively, the bidirectional cavopulmonary shunt is very effective and safe palliative or pre-Fontan stage operation for the many complex congenital anomalies with low pulmonary blood flow especially for the patients who have the risk of Fontan repair.

The risks of homologous blood transfusion are well documented and recently increased with the emergence of acquired immunodeficiency syndrome. This is a report concerning 29 consecutive adult with no blood conservation patients (Group I) who had an elective cardiac operations. A similar group of 29 patients operated on 1992 but with blood conservation (Group II). In I of Group I patients and 15 of Group II patients, no homologous blood products were required. Group II patients used significantly less fresh frozen plasma (2.05${\pm}$0.68 unit versus 6.52${\pm}$0.72 unit, p<0.05) and the homologous blood transfusion (0.42${\pm}$0.9 unit versus 3.64${\pm}$0.17 unit, p<0.05) than Group I patients. Group II patients had also significantly less postoperative bleeding (338${\pm}$39.9 ml versus 585${\pm}$93.0 ml, p<0.05) than Group I patients. Group II patients recieved 460${\pm}$62.6 ml of mediastinal shed blood in acquired group. In conclusion, a simple and inexpensive blood conservation program, mainly combining autologous blood removal before bypass, retransfusion of the volume remaining in the oxygenator, and consistent autotransfusion of mediastinal shed blood has enabled us to avoid infusion of homologous blood in 15/29 patients of Group II patients. No side effects or complicatinos could be related to the blood conservation program.

Radiotherapy, as a major 3 standard treatment for cancer, traditionally it has been useful treatment that aim of curative or palliative setting. In addition to some proliferative or inflammatory benign disease are also included in field of radiotherapy. Unlike cancer, in the case of benign disease, it shows good treatment result from usage of some medication, conservative management or surgery. But if fail of these treatment or impossible, low dose radiotherapy is use adjuvant or replacement treatment so that there are no harmful side effect result in safety and easy management for reduce pain or recurrence. Recently, the technical advances in radiotherapy that have been achieved make preservation of normal tissue and the clinical application of high precision radiotherapy focus to selective lesions is possible, and it makes useful treatment in senile patients especially.

The ideal approach in the staged management of patients with pulmonary atresia has been a challenging problem and the result has not been always satisfactory. We reviewed our early result of initial palliative surgeries in fifteen cases of pulmonary atresia with interventricular communication Included are eight cases of simple pulmonary atresia with ventricular septal defect and seven cases of pulmonary atresia associated with other complex cardiac anomalies. The ages of the patients were less than one year except one. The morphology of pulmonary vasculature was highly variable and showed unfavorable conditions in most cases. Pulmonary artery was nonconfluent in two. Two-thirds of all cases showed significant problems such as juxtaductal stenosis or diffuse hypoplasia. The ductus arteriosus usually narrowed at its pulmonic end. Initial palliation was done by modified Blalock-Taussig shunt in six, central shunt with or without pulmonary angioplasty in five, right ventricular outflow tract [RVOT] reconstruction in three and direct connection of nonconfluent pulmonary arteries with bilateral cav-opulmonary shunt in one patient. There were 3 hospital deaths. Two of them underwent simultaneous repair of the associated anomaly of TAPVR. Among the six patients who received modified Blalock-Taussig shunt, three needed early second palliative procedure by central shunt, RVOT patch reconstruction and pulmonary angioplasty in each case, All patients who received central shunt showed marked clinical improvement. Among the twelve patients who survived the palliative procedures, two patients underwent total correction 13 months and 18 months after initial palliation respectively. We think that the choice of palliative procedure must be individualized according to the morphology of the pulmonary arteries. More experience and long term follow-up data are necessary to meet this challenging problem.

Distant metastases of head and neck cancer have become an increasingly common cause of death as local and regional control has improved. The most frequent metastatic sites of head and neck cancer are the lung, liver, bone and kidney; but metastases to the gastrointestinal tract, brain and heart have also been reported. We report a recent case of a 37-year-old male patient with squamous cell carcinoma of the tonsil who had undergone composite operation with left radical neck dissection and postoperative radiotherapy. The patient presented three years later, cachexic and complaining of severe deep seated headache. Radiologic evaluation revealed a cystic mass with peripheral enhancement in left temporal lobe that was proven to be metastatic cancer by burrhole exploration. However, in spite of various modalities, the patient expired.

In unresectable stage IV colorectal cancer, the role of palliative surgery is not defined clearly. The palliative surgery can be categorized into two surgeries; first, palliative primary tumor resection; second, palliative metastatectomy. Several retrospective studies reported initial palliative systemic chemotherapy in unresectable stage IV colorectal cancer did not increase primary tumor related complications such as obstruction, perforation and hemorrhage, so they insisted that primary tumor resection in asymptomatic stage IV colorectal cancer should be preserved. However, in terms of overall survival and cancer-specific or progression-free survival, several retrospective studies, especially using population-based big data, reported favored survivals in palliative primary tumor resection group. And also several studies reported that palliative metastatectomy such as liver resection without resection of lung metastasis showed better overall survivals. But those results from those studies came from retrospective studies and are likely to be affected by selection bias. Prospective randomized studies are needed to define the benefit of palliative primary tumor resection and metastatectomy in unresectable stage IV colorectal cancer. However, based on the updated evidences, the dogma that palliative primary tumor resection should be preserved in asymptomatic unresectable stage IV colorectal cancer should be questioned.

The current standard of treatment for differentiated thyroid cancer is surgical resection followed by radioactive iodine therapy according to the recurrence risk. However, external beam radiotherapy may be recommended in limited cases where surgical resection is impossible or residual gross lesion remains or the aforementioned standard therapy is deemed insufficient in achieving local control. We report a case of 59 year old patient who presented with advanced papillary thyroid carcinoma of right neck but was unable to receive surgical resection due to underlying Eisenmenger syndrome. He received radiation therapy of 67.5 Gy in 30 fractions with palliative aim with no further treatment and has been maintaining long-term stable disease state for 38 months. Herein, we report a rare case of palliative aim radiation therapy alone for advanced papillary thyroid carcinoma with literature review.

Background : Bilateral pulmonary thromboendarterectomy(PTE) is recognized as the definitive treatment for chronic thromboembolic pulmonary hypertension (CTEPH). We investigated the symptomatic, hemodynamic and prognostic effects of PTE in comparison with medical treatment. Methods : Twenty-four patients diagnosed with CTEPH from 1995 to 2003 at the Asan Medical Center were divided into two groups: patients treated with PTE(PTE group, n=12) and those not treated with PTE(Med group, n=12). The serial changes in dyspnea, the tricuspid regurgitation maximal velocity (TRVmax) and survival of the PTE and Med groups were compared retrospectively. Results : In PTE group, during a follow-up period of 1 year, the New York Heart Association(NYHA) functional class significantly improved, while there was no significant improvement in the Med group. PTE significantly lowered the TRVmax from $4.23{\pm}0.54m/sec$ to $3.22{\pm}0.70m/sec$ over a follow up period of 2 years. (p=0.028) However, the TRVmax in the medically treated group did not show any significant improvement, changing from $3.98{\pm}0.68m/sec$ to $4.27{\pm}0.95m/sec$ during 1 year. The 5-year survival of the PTE group was 77.9% compared with 64.3% in the medically treated group. Conclusion : PTE provides substantial long-term improvement in dyspnea and the echocardiographic changes compared with medically treated patients.

Purpose : To evaluate the effectiveness of external radiation therapy and the prognostic factors, we retrospectively analyzed therapeutic results of malignant extrahepatic biliary obstruction (EHBO). Methods and Materials : We analyzed the results of the external radiation therapy in 59 patients of inoperable malignant EHBO who had been treated with more than 10 Gy of external radiation therapy from April 1984 to December 1990. There were 21 stomach cancer ($35.6\%$), 12 pancreas cancer ($20.3\%$), 15 extrahepatic biliary cancer ($18.0\%$) and 11 another cancer ($18.0\%$). Their pathologies were confirmed in 31 patients ($52.5\%$). They divided into 27 adenocarcinoma and 4 nonadenocarcinoma. Their chief complaints were jaundice in 47 patients ($79.7\%$) and abdominal pain in 15 patients ($49.2\%$). Twelve patients had slightly increased bilirubin level in liver function test without jaundice. We treated twenty four patients ($40.6\%$) with percutaneous transhepatic biliary drainage (PTBD) and 32 patients ($54\%$) with systemic chemotherapy (CT). We performed external radiation therapy (ERT) upto $10.8\~55.8$ Gy (median 37.8 Gy) with palliative aim. Results : Overall median survival duration was $7.80\pm1.15$ months. The response rates of jaundice were $81.8\%$ in PTBO group and $66.7\%$ in non-PTBD group without statistical significance. The improving rate of jaundice was not significantly different in decreased ratio of total bilirubin level. But abdominal pain was more decreased in CT group than non-CT group (p<0.05). The significant prognostic factors were high performance status (Karnofski Performance Status >70), total radiation dose more than 35 Gy and good response of pain after therapy. There were increased in bacterial cholagitis in PTBD group and gastrointestinal complications in CT group. Conclusion : External radiotheapy could improve jaundice and abdominal pain in malignant EHBO patients, Overall survival duration was prolonged in patients with higher performance status and patients who had been treated with more than 35 Gy of total radiation dose. In the future, we expect not only better palliative role but also the prolongation of survival of using the ERT combined with other treatment method. But to achieve certain conclusion, we need luther study consisted with many kinds of treatment methods including new technologies in RT.
