  • 목적 : 천막상부 약성 신경교종의 치료로서 수술 후 방사선 치료의 역할을 생존율을 중심으로 평가하며 그 예후 인자를 분석한다. 대상 및 방법 : 1985년 9월부터 1997년 3월까지 수술 후 방사선 치료를 받은 69례의 환자를 대상으로 분석하였고 나이의 범위는 7세에서 66세이며 중앙값은 47세였다. 42례(61$\%$)는 다형성 교모세포종 이었고 27례(39$\%$)는 악성 성상세포종이었다. 20례(29$\%$)는 Karnofsky 역할수행능력 점수가 80점 이상이었다. 43례(62$\%$)는 수술 전 3개월 이내에 증상을 호소하였다. 24례 (35$\%$)는 육안 상 완전 절제를, 40례(58$\%$)는 부분 절제를, 나머지 5례(7$\%$)에서는 뇌정위 조직검사만 시행하였다. 총 방사선 조사량은 50.4-61.2Gy(중앙값, 55.8; 최빈값, 59.4)로 하루 1.8-2.0 Gy 씩 33-83일 동안(중앙값, 48) 치료하였다. 단 3례는 수술 후 전신 상태의 불량으로 하루 3.0Gy 씩 각각 33, 36, 39Gy 까지 치료하였다. 추적 관찰율은 93$\%$였고 중앙간은 14개월이었다. 결과 : 전체 환자의 2년 및 3년 생존율과 중앙 생존기간은 각각 38$\%$, 20$\%$, 16개월이었다. 악성 성상세포종과 다형성 교모세포종의 중앙생존기간은 각각 34, 14개월이었다(p=0.0001). 완전절제, 부분절제, 뇌정위 조직검사군에서의 3년 생존율은 각각 38$\%$, 11$\%$, 0$\%$였다(p=0.02). 연령이 40세 미만, 40-59, 60세 이상 군의 3년 생존율은 각각 52$\%$, 8$\%$, 0$\%$였다(p=0.0007). 역할수행 능력점수 80점 이상과 80점 미만군의 3년 생존율은 각각 53$\%$, 9$\%$였파(p=0.008). 상기와 같이 절제 정도에 따른 3개의 수술 군과 3개의 연령 군을 포함한 다요인 분석에서 병리학적등급, 수술 정도, 연령이 유의한 인자였다. 그러나 2개의 수술 군(완전절제와 비완전 절제)과 2개의 연령 군(50세 미만과 50세 이상)을 공변량으로한 다요인 분석에서 연령대신 병리학적 등급, 수술 정도, 역할수행 능력이 유의한 인자였고, 이들 세 가지 요인을 갖춘 5례는 치료와 관련한 심각한 부작용 없이 3년 누적생존율이 100$\%$로 생존하고 있다. 결론 : 악성 신경교종의 치료에서 수술 후 방사선치료를 추가함으로써 기존의 수술 단독의 생존율을 향상시키는 역할을 확인할 수 있었다. 악성 성상세포종 환자 중, 특히 양호한 역할수행 능력과 완전 절제를 받은 환자군의 생존율이 가장 양호하였다. 다형성 교모세포종 환자에서는 특히 젊은 나이인 경우 적절한 신경학적 기능보존과 함께 최대한의 종양 절제가 선행되어야 할 것으로 생각된다. 그러나 양호한 예후 인자를 갖지 못한 대부분의 다형성 교모세포종 환자군의 생존율은 여전히 좋지 않아 이 환자 군에서는 수술 후 통상적인 방사선 치료보다는 다른 적극적인 치료가 추가 또는 시도되어야 할 것으로 생각된다.

  • Background Recently, modern technology such as diffusion tensor imaging (DTI), neuro-navigation and intraoperative neurophysiological monitoring (IOM) have been actively adopted for the treatment of thalamic tumors. We evaluated surgical outcomes and efficacy of the aforementioned technologies for the treatment of pediatric thalamic tumors. Methods We retrospectively reviewed clinical data from 37 children with thalamic tumors between 2004 and 2017. There were 44 operations (27 tumor resections, 17 biopsies). DTI was employed in 17 cases, neuro-navigation in 23 cases and IOM in 14 cases. All diagnoses were revised according to the 2016 World Health Organization Classification of Tumors of the Central Nervous System. Progression-free survival (PFS) and overall survival (OS) rates were calculated, and relevant prognostic factors were analyzed. The median follow-up duration was 19 months. Results Fifteen cases were gross total resections (GTR), 6 subtotal resections (STR), and 6 partial resections (PR). Neurological status did not worsen after 22 tumor resections. There were statistically significant differences in terms of the extent of resection between the groups with DTI, neuro-navigation and IOM (n=12, GTR or STR=12) and the group without at least one of the three techniques (n= 15, GTR or STR=9, p=0.020). The mean PFS was $87.2{\pm}38.0$ months, and the mean OS $90.7{\pm}36.1$ months. The 5-year PFS was 37%, and the 5-year OS 47%. The histological grade ($p{\leq}0.001$) and adjuvant therapy (done vs. not done, p=0.016) were significantly related to longer PFS. The histological grade (p=0.002) and the extent of removal (GTR/STR vs. PR/biopsy, p=0.047) were significantly related to longer OS. Conclusion Maximal surgical resection was achieved with acceptable morbidity in children with thalamic tumors by employing DTI, neuro-navigation and IOM. Maximal tumor resection was a relevant clinical factor affecting OS; therefore, it should be considered the initial therapeutic option for pediatric thalamic tumors.

  • Objective : The aim of the present study was to identify whether the deformity angular ratio (DAR) influences the occurrence of complications after posterior vertebral column resection (PVCR) and to establish the DAR cut-off value. Methods : Thirty-six consecutive patients undergoing PVCR from December 2010 to October 2016 were reviewed. The relationships between the total, sagittal, and coronal DAR and complications were assessed using receiver operator characteristics curves. The patients were divided into two groups according to a reference value based on the cut-off value of DAR. Demographic, surgical, radiological, and clinical outcomes were compared between the groups. Results : There were no significant differences in the patient demographic and surgical data between the groups. The cut-off values for the total DAR (T-DAR) and the sagittal DAR (S-DAR) were 20.2 and 16.4, respectively (p=0.018 and 0.010). Both values were significantly associated with complications (p=0.016 and 0.005). In the higher T-DAR group, total complications (12 vs. 21, p=0.042) and late-onset complications (3 vs. 9, p=0.036) were significantly correlated with the T-DAR. The number of patients experiencing complications (9 vs. 11, p=0.029) and the total number of complications (13 vs. 20, p=0.015) were significantly correlated with the S-DAR. Worsening intraoperative neurophysiologic monitoring was more frequent in the higher T-DAR group (2 vs. 4) than in the higher S-DAR group (3 vs. 3). There was no difference in neurological deterioration between the groups after surgery. Conclusion : Both the T-DAR and the S-DAR are risk factors for complications after PVCR. Those who had a T-DAR >20.2 or S-DAR >16.4 experienced a higher rate of complications after PVCR.

  • Background: Lung cancer is the most common cause of cancer mortality in Korea. The TNM stage at presentation in patients with non-small cell lung cancer (NSCLC) has the greatest impact on prognosis. Patients who undergo a complete resection for NSCLC are likely to develop recurrent and/or metastatic disease. There are several factors influencing the development of recurrence. We explored risk factors of recurrence in patients with stages I and II NSCLC, who had undergone curative resection. Methods: We reviewed patients who had complete surgical resection as definitive treatment for stage I or II. Patients followed up for more than 36 months. We evaluated several factors which might have relationship with recurrence, such as patient's demographic factors, TNM staging, pathologic finding, tumor markers and surgical technique. Results: A total of 75 patients were enrolled for analysis, of whom 58 were men and 17 were women with mean age of 61 (range, 37 to 76) years. The average size of tumors was 3.9 cm (0.7 to 10 cm). There were 64 patients with stage I NSCLC and 11 with stage II NSCLC. Among 64 patients with stage I NSCLC, 35 patients showed recurrences whereas 8 patients have recurred in stage II NSCLC. Grade of differentiation of tumor was closely related to the recurrence. Seventy-five percent of patients who had poor tumor differentiation experienced a recurrence. In contrast, 3 patients of twelve had recurrences, who revealed differentiation in their tissue (p<0.05). Conclusion: Tumor differentiation could be a predictive factor for tumor recurrence in patients who have undergone curative resection for stage I or II NSCLC.

  • 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.

  • Background: Liposarcoma of the spermatic cord is rare and frequently misdiagnosed. The standard therapeutic approach has been radical inguinal orchiectomy with wide local resection of surrounding soft tissues. The current trend of organ preservation in the treatment of several cancers has started to evolve. Herein we present our testis-sparing surgery experience in the treatment of spermatic cord liposarcoma and a pooled analysis on this topic. Materials and Methods: Clinical information from patient receiving organ-sparing surgery was described. Clinical studies evaluating this issue were identified by using a predefined search strategy, e.g., Pubmed database with no restriction on date of published papers. The literature search used the following terms: epidemiology, surgery, chemotherapy, radiotherapy, testis sparing surgery, spermatic cord sarcomas/liposarcomas. Results: Patient received a complete excision of the lesion, preserving the spermatic cord and the testis. The final pathological report showed a well differentiated liposarcoma with negative surgical margins and no signs of local invasion. After 2-year of follow-up, there was no evidence of local recurrence. Since the first case reported in 1952, a total of about 200 well-documented spermatic cord liposarcoma cases have been published in English literature. Among these patients, only three instances were reported to have received an organ-sparing surgery in the treatment of spermatic cord liposarcoma. Conclusions: Radical inguinal orchiectomy and resection of the tumor with a negative microscopic margin is the recommended treatment for liposarcoma of the spermatic cord. But for small, especially well-differentiated, lesions, testis-sparing surgery might be a good option if an adequate negative surgical margin is assured.

  • Objective : The surgical approach for recurrent pituitary adenoma after trans-sphenoidal approach (TSA) is challenging. We report the outcomes of the endoscopic TSA for recurrent pituitary adenoma after microscopic TSA. Methods : From February 2010 to February 2013, endoscopic TSA was performed for removal of 30 recurrent pituitary adenomas after microscopic TSA. Twenty-seven (90%) patients had a clinically non-functioning pituitary adenoma. Twenty-four (80%) patients suffered from a visual disturbance related to tumor growth. The clinical features and surgical outcomes were retrospectively analyzed for the ophthalmological, endocrinological, and oncological aspects. Results : The mean tumor volume was 11.7 $cm^3$, and gross total resection was achieved in 50% of patients. The volumetric analysis based on the postoperative MR showed that the mean extent of resection rates were 90%. Vision was improved in 19 (79%) of 24 patients with visual symptoms, and endocrinological cure was achieved in all of three functioning pituitary adenomas; however, the post-operative follow-up endocrinological examination revealed a new endocrinological deficit in one patient. Two patients required antibiotics management for post-operative meningitis. Conclusion : The endoscopic TSA can be an effective treatment option for recurrent pituitary adenoma after microscopic TSA with acceptable outcome.
