Giant cell tumor of the temporal bone (osteoclastoma)

A 49-year-old white female patient was referred to the ENT Department, Zentralkrankenhaus, Bremen, because of conductive hearing loss. Widespread tumor formation was found in the left temporal bone and was identified by biopsy to be an osteoclastoma. The tumor was extirpated surgically and reconstruction was performed. Periodic clinical follow-ups during a 36-month period after surgery have included control computed tomographic scans and have shown no evidence for recurrent disease. The specific pathology of the osteoclastoma is presented and different ways for treatment are discussed.     

Adult granulosa-cell tumor of the ovary: a retrospective study of 45 cases

This study describes 45 cases of adult granulosa-cell tumors seen in our institution between 1976 and 1993. The median age was 46.5 years (12–77) and 18 women were postmenopausal. Vaginal bleeding was present in one-third of cases; other complaints were abdominal pain (28%) and the presence of a pelvic mass (47%). The tumor size was variable (<3 cm to 30 cm, median 11.5 cm). FIGO stages were: stage I: 30 (73%) (19 Ia, seven Ic, four I unknown); stage II: seven (17%) (two IIa, five IIC); stage III: three (7%) (one IIIb, two IIIc). Two adenocarcinomas and 13 cases of hyperplasia were found in 25 endometrial samples available. The initial therapy for all the cases was surgery, consisting in 34 patients of hysterectomy, bilateral salpingo-oophorectomy, ± tumor resection. Sixteen patients received adjuvant therapy as well: chemotherapy (CT) alone for 12, radiotherapy (RT) alone for two, and CT + RT for two patients. Among the 39 patients who achieved a complete response after initial therapy, 15 patients have relapsed (pelvic recurrences) (38.5%) including six stage Ia (three received only conservative surgery). All the recurrent tumors were resected and 14/15 had CT (13/14 with cisplatin). The overall survival rate was 77.2% at 5 years, 66.5% at 10 years, and 41.2% at 20 years. A statistically significant difference was found between the survival of patients with stage Ia disease (75% at 10 and 15 years) and that of other patients (60% at 10 years, and <50% at 15 years). Serum estradiol and serum inhibin were measured in some patients and the results are described.     

Prognostic value of serial CA125 measurements during chemotherapy for patients with advanced ovarian cancer

Serum CA125 concentrations measured before and during chemotherapy may provide additional information for prognostic assessment of patients with epithelial ovarian cancer (EOC), and enable discrimination between patients who are likely to benefit from further therapy and those who will not. Medical records of 40 patients with advanced EOC, treated at the Department of Obstetrics and Gynecology of the University Hospital Nijmegen between July 1984 and April 1993, were examined. All patients had primary cytoreductive surgery followed by platinum-based chemotherapy. Serum samples were obtained before surgery and during chemotherapy. Follow-up information and patient and tumor characteristics were abstracted from medical records until December 1, 1994. By using multivariate Cox proportional hazards models for disease-free and overall survival it was evaluated whether outcome prediction was improved by inclusion of serum CA125 quantitations.
  Only FIGO stage and extent of residual tumor were significant independent prognostic factors before the start of chemotherapy. When such regression models were constructed after subsequent courses of chemotherapy, serum CA125 measurements conducted after each of the first three chemotherapy courses improved the prediction of disease-free survival. Prediction of overall survival was improved by inclusion of serum CA125 measurements after courses 1–6. Inclusion of serum CA125 measurements during chemotherapy improved prognostic assessment of patients with advanced EOC.     

GLOMUS TUMORS──A REVIEW OF 8 CASES WITH INTRODUCTION OF A MODIFIED COMBINED INTRA-AND EXTRACRANIAL APPROACH

Eight cases of glomus tumors hospitalized in our department from 1982 through 1995 were reviewed. It comprised of five glomus tympanic tumors and three glomus jugular tumors. Discussion was centered on it’s contemporary diagnosis, classification and surgical treatment with introduction of a modified combined intra-and extracranial surgical approach to resect the extensive glomus tumors.     

骨巨细胞瘤的生物学行为研究

本文对骨巨细胞瘤（ＧＣＴ）的传统组织学分级与其生物学行为不甚相符的原因进行了研究。采用５１例ＧＣＴ为研究对象，以１３例骨囊肿（良性）和１５例骨肉瘤（恶性）为对照组，采用图像分析仪（ＩＡＴ）对细胞核（ＧＣＴ取基质细胞核），进行了形态计量研究（８项参量），ＤＮＡ含量，ＤＮＡ倍体类型研究，及术后复发病例的ＤＮＡ倍性与其传统分级的比较研究。结果经统计学处理发现ＧＣＴⅠ级和Ⅱ级之间无显著差别，且它们的生物学属性在潜在恶性和低度恶性范畴。研究还揭示ＧＣＴ的ＤＮＡ≥５ｃ细胞数超过７％者系术后复发、转移的高危病例。     

Radiation therapy for intracranial germ cell tumors: Predictive value of tumor response as evaluated by computed tomography

Background This retrospective study analyzed the outcome in patients with intracranial germ-cell tumors to determine whether tumor response during radiation therapy can predict achievement of primary local control with radiation therapy alone. Methods Between 1983 and 1993, 22 patients with untreated primary intracranial germ cell tumors received a total whole brain radiation dose of between 18 Gy and 45 Gy (mean 31.3 Gy) with or without a localized field of 10 to 36.4 Gy (mean, 22.4 Gy), or local irradiation only (1 patient). In 10 patients with pineal tumor only, who were treated first with radiation therapy, tumor response to radiation therapy was evaluated using computed tomography (CT) (at baseline, and approximately 20 Gy and 50 Gy). Areas of calcification in the tumor were subtracted from total tumor volume. Follow-up time ranged from 2 to 12 years. Results Five-year actuarial survival rates for patients with germinoma were 71%, 100% for patients with a teratoma component, and 100% for patients without histologic verification. Patients with germinomas or tumors suspected of being germinomas who were given more than 50 Gy had no local relapse. There was no correlation between primary local control by radiation therapy alone and initial tumor volume. The rate of tumor volume response to irradiation assesed by CT was significantly different in those patients who relapsed compared to those who did not relapse Conclusion Tumor response during radiation therapy using CT was considered to be predictive of primary local control with radiation therapy alone.     

Tumor lysis syndrome in widely metastatic small-cell lung cancer

Tumor lysis syndrome is a rare complication of nonhematologic malignancies that results from massive necrosis of neoplastic cells after chemotherapy. This syndrome consists of life-threatening metabolic derangements, including severe hyperphosphatemia, hyperkalemia, hyperuricemia, and hypocalcemia, and may result in renal failure and death if not recognized early and treated appropriately. We report a case of tumor lysis syndrome after induction chemotherapy in a patient with widely metastatic smallcell lung cancer. This case emphasizes the importance of awareness and early treatment of this syndrome.
