폐암의 방사선 치료에 있어 전산화 단층 촬영을 이용한 치료계획에 관한 연구

조문준 충남대학교 의과대학 지역사회의학연구소 1990 충남의대잡지 Vol.17 No.2

To evaluate the usefulness of computerized tomography planning in lung cancer, dosimetric comparative study was done between conventional treatment plan and plan based on CT images. Dose distribution was compared between AP PA parallel opposing ports with posterior spinal cord block and AP PA parallel opposing ports with oblique ports based on CT images. CT plan was superior to conventional treatment plan.

Objectives : We report an interim result of conformal radiotherapy in a patient with early stage cancer at the base of the tongue, which developed in a previously irradiated area. Materials and Methods : A 64-year-old male patient was diagnosed with T4NOMO supraglottic cancer. He received 72Gy of radiation therapy from 21 November 1988 to 24 February 1989. He had local failure and underwent a salvage total laryngectomy on 28 August 1989. Subsequently, he did well. In early 1999, he suffered from throat pain. He had a 2.5cm ulcerative mass at the base of his tongue, in the area that had been irradiated previously. Biopsy showed squamous cell carcinoma. After workup, he was diagnosed with base of tongue cancer with T2NOMO. Surgery was not feasible because the morbidity was not acceptable. Since it was difficult to re-irradiate the area with a curable dose using conventional 2D radiation therapy with an acceptable morbidity, we decided to try conformal radiotherapy. We used 7 static beam ports with field sizes from 7×6.4 to 8×8㎠, using 6 and 10MV photons. The fractionation regimen was 1.8Gy, 5 times per week. He received 64.8Gy in 36 fractions from 9 April 1999 to 1 June 1999. Results : In the 21 months since radiotherapy, the patient has not experienced any acute or chronic complications, such as xerostomia. He experienced relief of pain shortly after the start of radiotherapy, showed a complete response, and is still doing well. Conclusion : Conformal radiotherapy can be used to treat cancer that develops within a previously irradiated field, with curative intent.

조문준,박승호,김재성,김선영 충남대학교 의과대학 지역사회의학연구소 1994 충남의대잡지 Vol.21 No.2

To evaluate the effect of radiation therapy in nonsmall cell lung cancer stage IIIB, we analyzed the 23 patients diagnosed NSCLC IIIB and treated curatively with radiation therapy between September 1989 and March 1993 at the department of therapeutic radiology, Chungnam National University Hospital, retrospectively. The actuarial 1 year survival rate was 39.2%, 2 year survival rate was 2.3%, and median survival time was 10 months. The difference of survival rates by performance status, response to radiotherapy, T stage, N stage, tumor size, age, pathologic cell type, combination with chemotherapy was not statistically significant. To increase the survival time and rate of the patients with NSCLC IIIB, further study for adequate radiation fractionation and dose, combination with chemoherapy and surgery will be needed.

진행암 환자에서 Cisplatin 병용화학요법 시 Ondansetron의 오심 구토 조절 효과

Ondansetron is a novel agent that selectively binds to the 5-hydroxytryptamine_3 receptor, and has been reported to have a prominent effect in the prevention of anti-neoplastic agent induced nausea and vomiting. Twenty solid tumor patients who were scheduled to receive cisplatin containing combination chemotherapy participated in a prospectively open-labeled study to evaluate the antiernetic efficacy and safety of ondansetron. The male to female ratio was 11 : 9 and median age was 49(16-70). The sites of primary neoplasms and number of patients were as following : head and neck 4, metastatic carcinoma of unknown primary site 3, stomach 3, osteosarcoma 2, ovary 2, esophagus 1, melanoma 1, penile 1, bladder 1, cervix 1, and extragonadal germ cell 1. Ondansetron was given as an 8mg loading dose IV before chemotherapy followed by 8mg IV every 8 hours until 24 hours after chemotherapy completion. Complete or major control(0 to 2 emetic episodes) of emesis was achieved in 17 of 20 patients(85%;complete 50%, major 35%) receiving ondansetron during the first 24hrs of chemotherapy. During the period of day 2 through clay 5 of chemotherapy, 14 of 20(75%) patients had complete or major control of emesis(complete 35%, major 35%). No severe side reactions were recorded in ondansetron treated patients, while mild to moderate headache was noted in 20% of patients. These results show that ondansetron is effective in the control of cisplatin induced nausea and emesis, and can be administered safely with minimal side effects.

To assess the effectiveness of palliative radiotherapy in the management of metastatic bone disease, 35 patients were retrospectively analyzed. Pain relief was obtained in 83% with excellent response in 56%. The most frequent primary tumor was lung cancer and followed by breast cancer, hepatoma and lymphoma. Spine, pelvis, upper and lower extremity were frequent metastatic site.

Malignant peritoneal mesothelioma is a rare neoplasm that arises from the mesothelium of a serosal cavity and is a rapidly fatal disease with a median survival of 4 to 12 months for untreated cases. Recently, we experienced a case with malignant peritoneal mesothelioma who was suspected hepatocelluar carcioma by abdominal CT scan and was confirmed by biopsy including immunohistochemical stain(calretinin) after surgery. We performed tumor excisions and wedge resection of the liver(segment Ⅷ)and inserted Tencoff catheter in abdominal cavity at 25th day of post-operation. We treated with intraperitoneal paclitaxel(25mg/m^(2)/day for 5 days) six courses monthly. She was well tolerable and is still living without any evidence of recurrence for 14th month of post-operation.

윌름종양의 치료에 대한 임상적 고찰

김재성,조문준,박경덕,설종구 충남대학교 의과대학 지역사회의학연구소 1995 충남의대잡지 Vol.22 No.2

Wilms' tumor is the paradigm for multimodal treatment of a pediatric malignant solid tumor. Developments in surgical techniques and postoperative care, recognition of the sensitivity of Wilms' tumor to irradiation, and the availability of several active chemotherapeutic agents led to a dramatic change in the prognosis for most patients with this once uniformly lethal malignancy. This article presents four cases of Wilms' tumor managed at Chungnam National University Hospital and reviews current treatment recommendations for patients with Wilms' tumor, based upon the results of the National Wilms' Tumor Studies.

방사선 조사에 의한 phospholipase D 활성화 연구

김영래,김기환,조문준,임규,황병두,박승길 충남대학교 의과대학 의학연구소 2002 충남의대잡지 Vol.29 No.1

Activation of oleate-dependent phospholipase D (PLD) isozyme by irradiation was reported previously. However, the effects of irradiation on other PLD isotypes (PLD1 and PLD2) have not been studied. There are several kinds of PLD isozymes in a cell. Therefore, it is difficult to study PLD isotype-specific activation in a cell by irradiation. We tested which isotype of PLD responds to irradiation. We used the fibroblasts cell lines overexpressing PLDl or PLD2 by introducing recombinant PLD1 or PLD2 cDNA. Phospholipids in cells were labelled with [(3)^H] myristic acid. Before irradiation, l-butanol was added. After irradiation with doses of 1, 2, and 10 Gray, we measured the formed phosphatidylbutanol containing [(3)^H] myristic acid. The overexpressed PLD isotypes were functional in those cell lines. PLD2 activity was enhanced by irradiation when we compared the PLD activations between control and PLD1 or PLD2 overexpressing cells. However PLD1 was not activated by irradiation. PLD2 isozyme, but not PLD1, was activated by irradiation. One Gray irradiation showed the maximal effect on PLD2 activation. The activation mechanism and physiological significance of PLD2 activation by irradiation remain to be uncovered.
