  • 고환암에서 mesna는 ifosfamide와 병용 투여하면 요관 계통의 부작용을 방지할 수 있으며, adriamycin과 같이 사용하는 경우 항암제의 세포증식 억제능을 감소시키지 않으면서 부작용을 경감 시킨다. 방사선 보호제의 sulfhydryl가 방사선에 의하여 발생하는 hydroxyl 유리기와 반응하여 조직을 보호할 수 있고, 역시 체내에서 유리기를 발생하는 adriamycin의 독작용을 musua가 감소시키는 사실에 근거하여, 쥐에 mesna와 방사선을 투여하여 mesna의 방사선보호 작용을 관찰하였다. 본 연구에서는 방사선 단독 처치군과 mesna와 방사선 처치군에서 고환의 수정관 내의 배아세포의 수와 형태적 변화를 현미경 하에서 매주 비교하고 재생 능력의 차이를 확인하였다. 양쪽 군에서 공히 초기에 세포 수가 감소하고 후기에 다시 세포가 증식 하였으며, 가장 세포 수가 적게 관찰된 시기는 방사선 조사 후 3주 째였다. 모든 관찰 기간에서 mesna 처치군의 평균 배아 세포수가 방사선 단독 처치군보다 통계적으로 유의하게 많이 관찰되었고(p<0.05), 또한 mesna 처치군에서 더 유효한 세포 재생 능력이 있음이 관찰되었다. 이는 mesna가 방사선 상해로부터 고환의 수정관 내 배아세포를 보호하고 있음을 입증하는 것으로 사료된다. Mesna가 고환 이외의 다른 조직을 방사선으로부터 보호할 수 있는지의 여부와 종양의 관해율을 저해하지 않을지에 대하여는 더 이상의 연구가 필요할 것으로 생각된다.

  • Generally early surgical extirpation is considered to be beneficial for the treatment of mediastinal tumors and prevention of its complication. The review of the clinical course, histopathologic characteristics and current diagnostic and treatment modalities will help us to decide when to treat and how to treat mediastinal tumors. For this purpose clinical analysis of the 42 patients who were surgically treated from July 1984 to August 1993 in the Chung Ang University Hospital is done in this report. There were 24 males and 18 females[1.3:1], and their age ranged from 1 year to 75 years. Nonspecific symptoms such as chest pain, cough and dyspnea were the most frequently encountered symptoms. Asymptomatic patients were relatively common[21.4%]. The tumors were found most frequently in the posterior mediastinum[45.2%]. Anterior mediastinum was the next and middle and upper mediastinum showed relatively rare occurrence of the tumor. Neurogenic tumor was the most common histopathologic type . Germ cell tumor, benign cyst and thymoma followed it. Curative resection was possible in 27 patients[64%], partial resection in 6 patients[14.3%]and just open biopsy in 7 patients[16.7%]. There was no early operative mortality. Postoperative complications were occurred in 5 patients[11.9%] and most of them were not serious.

  • Fine needle aspiration cytology of a pulmonary mass was performed on a 51-year-old man who had a left testicular mass. Cytologic features were composed of a homogeneous population of malignant cells associated with a background of foamy and lacelike material. The cellular features were characterized by monomorphous cell proliferation of relatively regular large cells, generally isolated or grouped. Occasionally, fine blanching stroma with large tumor cells and scanty lymphocytes were noted. The tumor cells had a round, regular nucleus, prominent round nucleoli, and a thin rim of cytoplasm containing large vacuoles or lacunae filled with glycogen. The fine needle aspiration cytologic diagnosis was highly consistent with metastatic seminoma from testis and less likely primary or other metastatic carcinoma. The diagnosis of resected testicular mass was classic seminoma. Despite the fact that cytopathologists were not familial with diagnosis of seminoma due to clinician's lack of interest in fine needle aspiration cytology of germ cell tumors including seminoma, it appears that a diagnosis of this tumor should not be problematic in cytologic material if specific histologic criteria are applied.

  • Teratomas arising from totipotential primitive germ cell are composed of 2 or 3 germ cell layers. We reviewed the records of 166 children who underwent the operation for teratoma from Jan, 1990 through April, 2007. There were 40 boys and 126 girls (average age $6.93{\pm}5.83$ years). Primary sites were ovary (n = 88), sacrococcygeum (n = 24), testis (n = 16), retroperitoneum (n = 16), mediastinum (n = 8), brain (n = 4), thymus (n = 3) and a single tumor involved the adrenal gland, neck, middle ear, oropharynx, stomach, pelvis, omentum, chest wall and scalp. Teratomas were mature in 141 patients, and immature in 25. Six patients who had ovarian immature teratomas grade 2 or 3 with peritoneal gliomatosis underwent adjuvant chemotherapy. During follow up period, 6 mature teratomas recurred at sacrococcygeal area (n = 1) and contralateral ovary (n = 5). Five patients of them underwent reoperation and diagnosed as a mature teratoma, but one who had underwent a left salpingooophrectomy with right ovary cystectomy at initial operation was observed carefully. Teratomas were dominant in female patients and developed at various organs. Complete excision was needed for good prognosis. In case of immature teratoma, complete excision and appropriate chemotherapy according to grading can contribute to favorable results.

  • Germinoma associated with chronic granulomatous inflammation of pineal gland has been rarely reported in the literature. The mechanism of chronic granulomatous inflammation is not understood well. We report a case of chronic granulomatous inflammation in pineal germinoma. In a 17 year-old male who suffered from headache and diplopia for six months, the mass of pineal gland was detected by brain MRI and removed through occipital transtentorial approach. The pathological specimen revealed the mass was predominantly composed of chronic granulomatous inflammation associated with small portion of germ cell tumor nests In the pathological interpretation of chronic granulomatous inflammation of pineal mass, it would be obliged to search for the presence of germ cell component.

  • Background: Non-epithelial malignant ovarian tumors and clear cell carcinomas, Brenner tumors, transitional cell tumors, and carcinoid tumors of the ovary are rare ovarian tumors (ROTs). In this study, our aim was to determine the clinicopathological features of ROT patients and prognostic factors associated with survival. Materials and Methods: A total of 167 patients with ROT who underwent initial surgery were retrospectively analyzed. Prognostic factors that may influence the survival of patients were evaluated by univariate and multivariate analyses. Results: Of 167 patients, 75 (44.9%) were diagnosed with germ-cell tumors (GCT) and 68 (40.7%) with sex cord-stromal tumors (SCST); the remaining 24 had other rare ovarian histologies. Significant differences were found between ROT groups with respect to age at diagnosis, tumor localization, initial surgery type, tumor size, tumor grade, and FIGO stage. Three-year progression-free survival (PFS) rates and median PFS intervals for patients with other ROT were worse than those of patients with GCT and SCST (41.8% vs 79.6% vs 77.1% and 30.2 vs 72 vs 150 months, respectively; p=0.01). Moreover, the 3-year overall survival (OS) rates and median OS times for patients with both GCT and SCST were better as compared to patients with other ROT, but these differences were not statistically significant (87.7% vs 88.8% vs 73.9% and 170 vs 122 vs 91 months, respectively; p=0.20). In the univariate analysis, tumor localization (p<0.001), FIGO stage (p<0.001), and tumor grade (p=0.04) were significant prognostic factors for PFS. For OS, the univariate analysis indicated that tumor localization (p=0.01), FIGO stage (p=0.001), and recurrence (p<0.001) were important prognostic indicators. Multivariate analysis showed that FIGO stage for PFS (p=0.001, HR: 0.11) and the presence of recurrence (p=0.02, HR: 0.54) for OS were independent prognostic factors. Conclusions: ROTs should be evaluated separately from epithelial ovarian cancers because of their different biological features and natural history. Due to the rarity of these tumors, determination of relevant prognostic factors as a group may help as a guide for more appropriate adjuvant or recurrent therapies for ROTs.

  • We conducted a retrospectively reviewed of the literature published of patients underwent fertility-preserving treatments for cervical, endometrial and ovarian cancers using the WANFANG database in Chinese. A majority were retrospective studies and case reports. With cervical cancer, radical trachelectomy(RT) in combination with pelvic lymphadenectomy could preserve the fertility of patients with early stage IA1-IB1 cancers, Tumor size ${\leq}2cm$ should be emphasized as the indication of RT in considering of the higher recurrent rate in patients with tumor size >2cm. For endometrial cancers, there is much experience on it. Given accurate pretreatment assessment, hormonal therapy is feasible management option to preserve fertility in young patients with early stage lesions that limited to the endometrium and well differentiated. High dose progestin have been applied, oral medroxyprogesterone acetate (MPA), 250-500mg/day, megestrol acetate 160-480mg/day. Other therapies that have been used in a limited number of cases include GnRH analog, intrauterine devices (IUDS) containing progestogen, usually combination of these therapies. All patients should be followed up by ultrasound and/or MRI evaluation, and endometrial curettage at intervals of 3 months. With ovarian cancer, in China, fertilitypreserving surgery in patients with stage IA (grade G1) of epithelial ovarian tumor and patients with germ cell tumor and borderline ovarian tumor have been successfully performed.

  • Purpose: Cisplatin-based chemotherapy has been commonly used for the treatment of intracranial germ cell tumors (IC-GCTs). However, this treatment exhibits some adverse effects such as renal problems and hearing difficulty. Carboplatin-based chemotherapy was administered to pediatric patients with IC-GCTs from August 2004 at the Samsung Medical Center. In this study, we assessed the responses and adverse effects of carboplatin-based chemotherapy in pediatric IC-GCTs patients according to the risk group, and compared the results with those of the previous cisplatin-based chemotherapy. Methods: We examined 35 patients (27 men and 8 women) diagnosed with IC-GCTs between August 2004 and April 2008 and received risk-adapted carboplatin-based chemotherapy at the Samsung Medical Center. Patients were divided into either low-risk (LR) or high-risk (HR) groups and a retrospective analysis was performed using information from the medical records. Results: Although hematological complications were common, hearing difficulties or grade 3 or 4 creatinine level elevation were not observed in patients who underwent carboplatin-based chemotherapy. The frequency of febrile neutropenia did not differ between the risk groups. The overall survival was 100% and event-free survival (EFS) was 95.7%. The EFS rate was 100% in the LR group and 90% in the HR group, respectively. Conclusion: Despite their common occurrence in high-risk patients, no lethal hematological complications were associated with carboplatin-based treatment. The current carboplatin-based chemotherapy protocol is safe and effective for the treatment of pediatric patients with IC-GCTs.
