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.

Adult fibrosarcoma is a malignant tumor comprising of spindle-shaped fibroblasts with variable collagen production. Due to their aggressive nature and high probability of local tumor recurrence, these tumors require accurate diagnosis and resection according to guidelines. A 57-year-old male presented to the clinic with a complaint of a palpable growing mass in the left scapular area. Examination of the back revealed a 6 cm protruding tumor with a nodular surface. We performed a wide excision, including the infraspinatus fascia layer and subsequent reconstruction using a parascapular island flap. Histopathological analysis demonstrated the typical microscopic features of adult fibrosarcoma. At the 3-year follow-up, there was no evidence of local recurrence and the resection margin was completely clear of tumor.

목적: 거대세포종은 대부분 대퇴골 원위부 및 경골 근위부에 주로 발생하며, 병소 내 소파술에서 광범위 절제술까지 다양한 수술 방법들이 시행되고있다. 저자들은 수술이 어렵고 재발율이 높은 슬관절 부위의 거대세포종 환자에서 재발율을 포함한 치료 성적을 분석하고, 재발율과 관련된 인자를 규명하고자 하였다. 대상 및 방법: 병리학적으로 확진 되고, 고속 바(high-speed burring)와 골 시멘트를 이용한 병소내 소파술을 시행 한 41예의 슬관절 주위 거대세포종 환자를 대상으로 하였다. 재발율과 기능적 평가를 통한 치료 성적을 분석하였으며, 성별, 연령, 종양의 위치, 크기, 연골 하골의 침범과 관절 내 침범 유무 그리고 Campanacci 분류에 따른 인자들과 재발율과의 상관관계를 통계적으로 분석하였다. 평균 추시 기간은 50(12~122) 개월이었다. 결과: 최종 추시 상 재발율은 17%였고, 재발시기는 평균 술 후 10개월이었다. Musculoskeletal Tumor Society (MSTS) Grading System에 의한 술 후의 기능 평가점수는 평균 27.8(93%)로 78%에서 만족스러운 기능을 보였다. 성별, 연령, 종양의 위치, 크기, 연골 하침범, 관절 내 침범, Campanacci 분류 등은 종양의 국소 재발과 통계적으로 유의한 상관 관계를 보이지 않았다. 결론: 슬관절 주변 거대세포종의 재발과 관련된 인자를 찾지는 못하였다. 수술적 치료로서 고속 바를 이용한 세심한 소파술과 골시멘트 충진술을 이용한 국소 절제술 만으로도 만족할 만한 결과 및 재발율을 얻을 수 있었다.

점막형 악성흑색종 10례에 대한 임상분석 결과 비강에서 가장 호발하였고 증상은 비폐색이 가장 많았다. 치료 성적은 수술을 우선적으로 선택한 후 방사선요법을 시행한 경우군에서 평균생존기간이 20.8개월이었고 방사선치료를 우선적으로 선택한 경우군에서는 14.7개월로, 접막형 악성흑색종의 경우 광범위 절제술 후 방사선요법을 시행하는 것이 도움이 될 것으로 생각되나 윈격전이 6례를 포함한 8례의 환자에서 재발이 있어 예후가 극히 불량한 암종으로 생각된다.

Objective : Intracranial hemangiopericytomas (HPCs) are rare tumors with aggressive behavior, including local recurrence and distant metastasis. We conducted this retrospective study to evaluate the efficacy of grossly total resection and adjuvant radiotherapy (RT) for these tumors. Methods : A total of 13 patients treated for intracranial HPC from January 1995 through May 2013 were included in this retrospective study. We analyzed the clinical presentations, radiologic appearances, treatment results, and follow-up outcomes, as well as reviewed other studies. Results : The ages of the patients at the time of diagnosis ranged from 26 to 73 years (mean : 48 years). The majority of the patients were male (92.3%), and the majority of the tumors were located in the parasagittal and falx. The ratio of intracranial HPCs to meningiomas was 13 : 598 in same period, or 2.2%. Seven patients (53.8%) had anaplastic HPCs. Nine patients (69.2%) underwent gross total tumor resection in the first operation without mortality. Eleven patients (84.6%) underwent postoperative adjuvant RT. Follow-up period ranged from 13 to 185 months (mean : 54.3 months). The local recurrence rate was 46.2% (6/13), and there were no distant metastases. The 10-year survival rate after initial surgery was 83.9%. The initial mean Karnofsky performance scale (KPS) was 70.8 and the final mean KPS was 64.6. Conclusion : Gross total tumor resection upon initial surgery is very important. We believe that adjuvant RT is helpful even with maximal tumor resection. Molecular biologic analyses and chemotherapy studies are required to achieve better outcomes in recurrent intracranial HPCs.

Objectives: To define the risk of occult cervical metastasis of maxillary squamous cell carcinoma (SCC) and the therapeutic value of elective neck dissection (END) in survival of clinically negative neck node (cN0) patients. Materials and Methods: Sixty-seven patients with maxillary SCC and cN0 neck were analyzed retrospectively, including 35 patients with maxillary gingiva and 32 patients with maxillary sinus. Results: Of 67 patients, 10 patients (14.9%) had occult cervical metastasis. The incidence of occult cervical metastasis of maxillary gingival SCC was higher than that of maxillary sinus SCC (17.1% and 12.5%, respectively). The 5-year overall survival rate was 51.9% for the END group and 74.0% for the non-END group. The success rate of treatment for regional recurrence was high at 71.4%, whereas that for local or locoregional recurrence was low (33.3% and 0%, respectively). Conclusion: The incidence of occult cervical metastasis of maxillary SCC was not high enough to recommend END. For survival of cN0 patients, local control of the primary tumor is more important than modality of neck management. Observation of cN0 neck is recommended when early detection of regional recurrence is possible irrespective of the site or T stage. The key enabler of early detection is patient education with periodic follow-up.

Background: To explore the relationship between persistent post-radiotherapy pain and locoregional recurrence in head and neck cancer patients. Methods: Five year retrospective data was reviewed of 86 patients of head and neck cancer treated with radiotherapy who continued to have pain at 6 weeks after completion of treatment. At follow-up after 3 months, these patients were stratified into: Group A (n = 39) constituted of patients whose pain subsided and Group B (n = 47) were patients who continued to have persistent pain. Results: At median follow-up time of 25 months (range: 8-47), one patient (2.6%) and 18 (38.3%) patients in group A and group B had locoregional recurrence respectively (P < 0.0001). Furthermore, group B patients had higher mean pain score levels as compared to group A (P = 0.03). Patients in whom pain subsided within 3 months had statistically much greater disease-free survival in comparison to those with persistent pain (P < 0.0001). Conclusions: Pain in head and neck cancer is an important symptom and should be considered a poor prognostic factor. In the current study, the majority of the patients with persistent pain had recurrent disease as compared to those in whom pain subsided within 3 months of post-treatment. It is suggested that patients with persistent pain need more intense follow-up and should be investigated thoroughly to detect recurrence at an early stage to provide a better quality of life.

Purpose: To evaluate the treatment outcomes of adjuvant external beam radiation therapy (EBRT) and vaginal brachytherapy (VB) following radical hysterectomy in cervical cancer patients with involved vaginal resection margin (VRM). Materials and Methods: We retrospectively reviewed the medical records of 21 patients treated with postoperative EBRT and VB for positive VRM FIGO stage IB-IIA cervical cancer between 2003 and 2015. Concurrent platinum-based chemotherapy was administered to all patients. Results: The median whole pelvis EBRT dose was 50.4 Gy (range, 45 to 50.4 Gy). In the VB, the median dose per fraction, number of fractions, and total dose delivered were: 4 Gy (range, 3.0 to 4.0 Gy), 4 fractions (range, 3 to 5 fractions), and 16 Gy (range, 12 to 20 Gy), respectively. At a median follow-up of 46 months (range, 9 to 122 months), local recurrence was observed in 2 patients, and distant metastasis was present in 7 patients. All patients with local recurrence subsequently developed distant metastases. The 5-year local control, disease-free survival, and overall survival rates were 89.1%, 65.9%, and 62.9%, respectively. Of the 21 patients, 7 patients (33.3%) reported grade 2 acute toxicity; however, there were no grade 3 or higher acute adverse events. Grade 1-2 late toxicities were observed in 8 patients. Late grade 3 urinary toxicity was reported in 1 patient. Conclusions: Adjuvant EBRT and VB showed excellent local control and low toxicity in cervical cancer patients with positive VRM. Although limited by its retrospective nature, the findings from our study provide evidence supporting the use of additional VB in pathologically involved VRM.
