Granular cell tumor (GCT) is a rare neoplasm occurring in the sellar and suprasellar spaces. It is a primary tumor of the neurohypophysis, presumably arising from the pituicytes, a distinctive glial cell of the neurohypophysis. GCTs in most reported cases show biologically benign behavior with slow growth. Only 70 cases of hypophyseal GCTs have been reported in the literature. We report a case of GCT in the neurohypophysis of a 46-year-old woman and discuss the histological and clinical features of this neoplasm together with the treatment modalities, reviewing the pertinent literature.

Background Our purpose was to investigate the role of helical tomotherapy using a simultaneous integrated boost technique for the treatment of high-grade gliomas near intracranial critical structures.Methods and materials Of 27 patients treated with helical tomotherapy, 11 were eligible. Only patients whose tumors were within 0.5 cm of the optic chiasm, the optic nerve or the brainstem were included. The therapeutic approach was a simultaneous integrated boost, prescribing 66 and 60 Gy to the PTV1 and PTV2, respectively, in 30 fractions. All patients received concomitant temozolomide at a dose of 75 mg/m2daily during radiation therapy.Results Of the 11 patients considered, 3 patients (27%) died after 4 months from the completion of the combined treatment. Three patients (27%) presented local progression, and the median time to disease progression was 6 months (range, 1–12). Five patients (45%), at the time of this evaluation, did not have signs or symptoms of recurrence or progression of the disease. Acute toxicity, evaluated during radiochemotherapy, was minimal, with all patients experiencing RTOG grade 0 and grade 1 toxicity.Conclusions Helical tomotherapy proved to be an effective and safe treatment modality, with an improvement of accuracy in delivery of highdose radiotherapy despite the presence of nearby critical structures.

We report on a very rare case of dorsal intramedullary melanocytoma in a 62-year-old man. The tumor was resected and gross total removal was achieved. During a 2-year follow-up period in which no radiotherapy was given, the tumor did not recur. We review the literature on these tumors and present disease criteria to distinguish melanocytoma from primary malignant melanoma. Patients and investigators should be cautioned that an intramedullary melanocytoma may recur and give rise to metastatic spread via the cerebrospinal fluid.

Background We report a leiomyosarcoma of the uterus, an uncommon tumor with a very aggressive course and poor prognosis due to the fact that, despite complete resection, it recurs with micrometastases. The most common metastatic sites are the lung, intraperitoneal, pelvic and paraaortic lymph nodes, and liver. Brain and skull metastases are very rare.Case A 57-year-old woman underwent a hysterectomy and bilateral salpingo-oophorectomy for a grade T2N0M0 uterine leiomyosarcoma. There was no evidence of other lesions. Three months later a total-body PET scan demonstrated the presence of metastases in both lungs, and the patient was started on chemotherapy. One year later a cranial MRI demonstrated a brain metastasis to the temporal lobe. Emergency complete resection of the recurrence was performed, followed by whole-brain radiation and adjuvant chemotherapy.Conclusions Given the limited treatment options, the gold standard for uterine leiomyosarcoma brain metastasis is total surgical removal. Chemotherapy and radiation therapy may provide only palliative benefit.

Aims and Background Gliosarcomas are rare malignant primary brain tumors that usually affect the fifth or sixth decades of life. The purpose of this study was to describe our experience with such lesions in elderly patients and to establish their prognosis factors.Methods Between 1993 and 2001, 7 patients over 60 years of age were treated at our institute for cerebral gliosarcomas. All patients underwent surgery for total or at least sub-total removal of a neoplastic mass.Results Owing to poor clinical conditions (Karnofsky performance score = 40), one patient was not treated postoperatively. Remaining patients were treated with whole-brain radiotherapy, whereas concomitant chemotherapy (temozolomide) was administrated only to 4 patients. Histological examination showed the prevalence of sarcomatous aspects in 3 patients; the gliomatous aspect prevailed in 4 patients.Conclusions Sarcomatous aspects and multimodality treatment (surgery, radiotherapy and chemotherapy) were associated with a better prognosis and showed in these elderly patients a trend similar to that of young people.

Aims and background The aim of the study was to evaluate the treatment of the extracranial metastases from glioblastoma multiforme in the elderly, discussing their uncommon occurrence and their pathogenesis.Methods The authors report seven cases of elderly patients (mean age, 69 years), with an initial diagnosis of cerebral glioblastoma multiforme, treated by a grossly total surgical removal and followed by adjuvant radiotherapy (64 Gy in 6 weeks, using Linac) and adjuvant chemotherapy (temozolomide both concomitant and sequential to radiotherapy).Results All patients presented a postoperative course characterized by good functional and clinical conditions (Karnofsky performance scale ≥70), which remained unchanged for a mean period of about 21 months (range, 16–23), with no neuroradiological signs of lesion regrowth. After this interval, new clinical signs occurred, and their clinical and radiological investigation showed metastatic repetitions in different sites: lung, liver, humerus and lymph nodes. All the metastases were surgically treated, but regrowth of the brain tumor and progression to deep important neural structures caused the patients’ exitus after a mean interval of about 10 months (range, 8–12) from the diagnosis of metastasis.Conclusions We found 128 cases of extra CNS metastases in the English literature. The main features of the patients of the previous reports and of those of the present series were analyzed. The main modalities of glioblastoma multiforme spread, the few theories about the rarity of metastasis, and the probable biological, histological and immunogenetic mechanisms involved in the pathogenesis are described. Although several studies have reported a poor outcome in elderly patients, they affirm that the treatment of those with a Karnofsky performance status >60 should be just as aggressive as in younger patients. This allows them to obtain a longer survival time and to also treat metastases, which are uncommon particularly in the elderly.

Aims and background Glioblastoma multiforme is the most common and most malignant primary brain tumor in adults. The current standard of care for glioblastoma is surgical resection to the extent feasible, followed by adjuvant radiotherapy plus temozolomide, given concomitantly with and after radiotherapy. This report is a prospective observational study of 43 cases treated in the Department of Radiotherapy, University of Rome La Sapienza, Italy. We examine the relationship between pathologic features and objective response rate in adult patients treated with concomitant radiation plus temozolomide to identify clinical, neuroradiologic, pathologic, and molecular factors with prognostic significance.Methods Forty-three consecutive patients (24 males and 19 females), ages 15-77 years (median, 57) with newly diagnosed glioblastoma multiforme, were included in this trial between 2002 and 2004 at our department. All patients were treated with surgery (complete resection in 81%, incomplete in 19%) followed by concurrent temozolomide (75 mg/m2/day) and radiotherapy (median tumor dose, 60 Gy), followed by temozolomide, 200 mg/m2/day for 5 consecutive days every 28 days. Neurologic evaluations were performed monthly and cranial magnetic resonance bimonthly. We analyzed age, clinical manifestations at diagnosis, seizures, Karnofsky performance score, tumor location, extent of resection, proliferation index (Ki-67 expression), p53, platelet-derived growth factor and epidermal growth factor receptor immunohistochemical expression as prognostic factors in the patients. The Kaplan-Meier statistical method and logrank test were used to assess correlation with survival.Results Fourteen patients (32%) manifested clinical and neuroradiographic evidence of tumor progression within 6 months of surgery. In contrast, 5 patients (12%) showed no disease progression for 18 months from the beginning of treatment. Median overall survival was 19 months. Multivariate analysis revealed that an age of 60 years or older (P <0.03), a postoperative performance score ≤70 (P = 0.04), the nontotal tumor resection (P = 0.03), tumor size >4 cm (P = 0.01) and proliferation index overexpression (P = 0.001) were associated with the worst prognosis. p53, PDGF and EGFR overexpression were not significant prognostic factors associated with survival.Conclusions The results suggest that analysis of prognostic markers in glioblastoma multiforme is complex. In addition to previously recognized prognostic variables such as age and Karnofsky performance score, tumor size, total resection and proliferation index overexpression were identified as predictors of survival in a series of patients with glioblastoma multiforme.

Aims and Background Late brain metastases from breast cancer are a rare event. Only a few cases have been reported in the English literature. The authors describe the clinical and pathological remarks, together with treatment modalities, removal extent and overall survival, of 11 patients in whom brain metastases were detected more than 10 years from the primary tumor.Patients and Methods Between January 1997 and April 2001, we hospitalized 11 patients, all females, with a histologically proven diagnosis of brain metastasis from breast invasive ductal carcinoma. We defined ‘late metastasis’ as those metastases that appeared at least 10 years after the breast cancer diagnosis. The median age at the moment of brain metastasis diagnosis was 59 years (range, 47-70), with a median latency time from breast cancer diagnosis of 16 years (range, 11-30).Results Ten patients underwent surgery followed by adjuvant radiotherapy (whole brain radiotherapy). Two of them received, after whole brain radiotherapy, stereotaxic radio surgery treatment. One patient had stereotaxic brain biopsy, performed by neuronavigator, followed by palliative corticosteroid therapy. Median survival after brain metastasis diagnosis was 28 months (range, 3 months-4 years).Conclusions Although late brain metastases are a rare event, specific neurologic symptoms and neuroradiological evidence of a cerebral neoplasm should be correlated to the presence of a cerebral metastasis, in a patient with a previous history of breast cancer. The longer latency time from breast cancer to brain metastasis could be explained by the “clonal dominance” theory and by different genetic alterations of the metastatic cell, which could influence the clinical history of the disease.

Aims and background Classical multiple sclerosis plaques usually have typical features on gadolinium-enhanced MRI scan. This non-neoplastic demyelinating process of the central nervous system generally does not produce focal space-occupying lesions associated with ring enhancement. However, atypical appearance of demyelinating lesions simulating a brain tumor is a possible well-known phenomenon.Methods We present our experience with 4 cases of multiple sclerosis indistinguishable clinically and neuroradiologically from a cerebral tumor. All patients underwent surgery.Results Histological examinations of all cases were positive for multiple sclerosis plaques.Conclusions The presented cases demonstrate the importance of considering a demyelinating disease in the differential diagnosis of a tumor-like brain lesion.

We report our remarks on 22 patients, 80 years of age and older, who were treated for glioblastoma multiforme. The 16 patients who underwent a multimodality treatment (surgery + radiotherapy + chemotherapy) had an average survival of 16.7 months versus the 5.8 months of the 8 patients treated with biopsy followed by radiotherapy and/or chemotherapy (log-rank test, P <0.001). Moreover, we point out the importance of MGMT hypermethylation as a significant prognostic factor: the 9 patients with nonmethylated MGMT had a mean survival of 7.7 months vs 17.9 months of the 13 patients with the MGMT promoter methylated (log-rank test, P = 0.0006). Several studies have pointed out age as an important negative factor for the outcome of elderly patients affected by glioblastoma multiforme. Elderly patients with a diagnosis of glioblastoma multiforme are thus generally excluded from clinical trials of treatment for the neoplasm, because it is a common opinion that the prognosis for such patients is particularly poor. On the contrary, according to our clinical and surgical experience, we firmly believe that patients older than 80 years with a histologically proven diagnosis of glioblastoma multiforme and in good health conditions (Karnofsky performance status >60) should be treated in the same way as younger patients.

The association between breast cancer and glioblastoma multiforme has not been amply analyzed in the literature. We describe 11 female patients with a diagnosis of glioblastoma multiforme who were treated when younger for breast cancer. We believe that this association is not due to chance but rather to genetic changes in hormone status and in particular to sex hormones. Another important point of view is represented by the chemotherapy treatment of breast cancer, which could have a carcinogenic effect and explain the growth of glioblastoma. This consideration, in our opinion, is important, because more effort should be made to understand the pathogenesis of glioblastoma multiforme and to improve the therapeutic approaches.

Aims and background To add a further contribution to the literature supporting the relationship between previous head trauma and development of glioma.Methods We report on four patients who developed brain gliomas in the scar of an old brain injury.Results All cases fulfilled the widely established criteria for brain tumors of traumatic origin. In all of our cases there was radiological evidence of absence of tumor at the time of the injury.Conclusions We believe that in specific cases it is reasonable to acknowledge an etiological association between a severe head trauma and the development of a glioma. This assumption is further sustained if there is radiological and surgical documentation of the absence of neoplasia at the moment of the trauma.

Radiotherapy is an important modality for the treatment of tumors and arteriovenous malformations affecting the central nervous system, even though several significant side effects have been described (radionecrosis, tumors, etc.). Meningiomas induced by high-dose radiation therapy are uncommon. In this study we describe five cases treated at our institute and review all previously published reports of meningioma occurring after high-dose radiotherapy. These tumors develop mainly in patients irradiated in childhood; their incidence peaks in the second decade of life, there is a predominance in females and a high frequency of malignant forms. Although rare, meningiomas may represent a late complication of radiation treatment. The behavior of the radiation-induced variety of meningioma seems to differ from that of its “spontaneous” counterpart. The use of radiotherapy should be carefully evaluated for relatively benign or congenital lesions which generally affect young patients with a long life expectancy.

Aims and Background The polychemotherapeutic regimen PEV (cisplatin, epidoxorubicin and vindesine) + lonidamine proved to be valid in terms of activity and efficacy in the treatment of patients with advanced, previously untreated non-small cell lung carcinoma. The goal of the study was to verify whether a different dose of lonidamine, together with an increase in cisplatin and epidoxorubicin compared to the standard regimen, is able to improve the activity and efficacy of PEV without increasing toxicity.Patients and Methods Thirty-one patients were treated with cisplatin (80 mg/m2/iv), epidoxorubicin (70 mg/m2/iv) and vindesine (3 mg/m2/iv) every 28 days for 6 courses in combination with lonidamine (600 mg/day on days 1 and 2 of each course followed by 450 mg/day until progression of disease or intolerance). All the patients were monitored for clinical response, median duration of response and survival and for toxicity.Results The clinical response in the 29 assessable patients was: 41.4% partial remission, 48.3% stable disease, and 10.3% progression of disease. The median duration of response was 8.5 months (range, 4-26+) and median survival was 12 months (range, 4-26+). Survival was above the median in 15 stage lIIb patients, and 2 patients were long survivors at 26+ months. The toxicity of PEV + lonidamine was mild; there were no toxic deaths nor acute toxicity of grade 4 according to the WHO scoring system.Conclusions Our polychemotherapeutic regimen proved to be valid in terms of activity and efficacy, and a further dose increase in single chemotherapeutic agents as well as lonidamine could therefore be justified.

Aims and Backround Ossifying fibroma is a tumor with benign course that rarely affects the cranial bones.Methods The authors report 5 cases of ossifying fibroma of the skull and analyze the clinical course and treatment of this lesione.Results 3 patients were females and 2 males. The mean clinical history was 3.2 years. 4 patients underwent total removal and 1 partial. At mean follow-up of 19 years, all patients who underwent total removal showed improvement of neurological deficit, whereas the patient who underwent partial removal had clinical regrowth.Conclusion The authors conclude that total removal of fibroma should be extended to normal bone and in cases in which total removal is not possible the residue should be checked for regrowth by serial MRI.

Aim and background The aim of this Phase II trial was to verify the therapeutic activity and tolerability of chemotherapy with lonidamine (LND) plus cyclophosphamide (CTX) in advanced non-small cell lung cancer (NSCLC) in the elderly. The rationale of the combination is reported. CTX showed mild toxicity, with a 12% objective response (OR) in monochemotherapy; LND potentiated the in vitro antiproliferative activity of alkylating agents, mainly CTX, without increasing myelotoxicity, particularly important in the elderly.Methods The schedule consisted of CTX, 600 mg/m2/i.v. on day 1 every 21 days for 6 cycles; LND, 450 mg/die/p.o. from day 1 to progression.Results Between November 1990 and April 1991, 41 patients with stage III–IV NSCLC were enrolled; 35 were assessable for response. Median age was 73 years (range, 71–79 years); 13 patients (32%) presented stage III A, 20 (49%) stage III b, and 8 (19%) stage IV disease. Cardiovascular conditions and/or chronic respiratory failure contraindicated surgical treatment in stage III A patients. Of enrolled patients, 14.6% experienced PR, 48.8% SD and 14.6% dropped out of the study. Median time to progression was 4 months (range, 2–9 months) and median survival 9 months (range 3–45 months). No patient showed WHO grade IV LND-related toxicity. In 1 patient (2.5%), LND was discontinued after 5 therapy cycles due to WHO grade III myalgia; in 80% of patients, LND oral dosage was reduced to 300 mg/day due to WHO grade II myalgia, and 20% of patients completed treatment with the full dose.Conclusions CTX plus LND can be considered a well tolerated therapeutic approach in the elderly with NSCLC with good PS and good liver, renal and cardiac conditions, but 14.6% PR is a slightly better result as compared with 12% PR obtainable with CTX alone as reported in the literature, even though most patients presented with advanced disease and no specific toxic effect was observed. Therefore, a confirmatory randomized trial (CTX vs CTS plus LND) would hardly be useful.

Multifocal gliomas fall into four main categories: diffuse, multiple, multicentric and multiple-organ. Multicentric gliomas are uncommon lesions of the central nervous system. Even more so are multicentric gliomas lying both above and below the tentorium (16 cases to date, as far we know). We report a clinical series of 7 cases, including 3 supra-Infratentorial tumors. The distinctive features of multicentric gliomas are mainly the absence of gross or microscopic connections and absence of seeding along easily accessible routes like the cerebrospinal fluid pathways or the median commissures. We consider the pathogenetic hypotheses and problems of diagnosis, especially differential from other multifocal diseases of the central nervous system.

Aims and Background Intramedullary teratoma is an extremely exceptional tumor (5 cases), although a careful review of international literature has shown it to be more frequent (32 cases) than believed.Methods The authors present a personal case with some unusual aspects.Results Our case is unusual not only because it was diagnosed by MRI (only one case has been reported in the literature) but also because surgical removal of the tumor was apparently total (only 4 other cases have been described), with a long follow-up period (4.5 years) and excellent results, in clinical and neuroradiologic terms.

We report our experience with 5 cases of post-Paget osteosarcoma of the skull, a rare lesion of the neurocranium. Four patients were treated by surgery and radiotherapy and one by surgery alone. Two patients received chemotherapy. Histologically, the tumor was found to be an osteosarcoma, fibroblastic in 2 cases, mixed in 2, and osteoblastic in 1. Combined treatment (surgery, radiotherapy and chemotherapy) positively influenced survival (median survival, 6 months). The prognosis for post-Paget osteosarcomas of the skull seems to be worse than for primary sarcomas, probably due to their intense vascularization. This facilitates the spread of tumor cells to other organs (as observed in our cases) and reduces the reduced effectiveness of chemotherapy. Although the latter lengthens survival and reduces the incidence of metastases, it is not as efficacious as in primary sarcomas.

Cancer frequently metastasizes to the brain, and such lesions, whether multiple or solitary, have a poor prognosis, despite all efforts to treat them. There have been recent sporadic reports of brain metastases from breast cancer responding for some years to antiestrogens (particularly tamoxifen) or bromocryptine. We report three cases of brain metastasis from cancer – two multiple and one a solitary lesion. The long survival of the patients – two for 5 years and one for 6 years, with more than an acceptable quality of life – should prompt therapeutic trials to test tamoxifen and designed to assess its effects on a sizable number of patients.

Aims and background Radiotherapy is important in the treatment of neoplasm of the central nervous system, but various side effects, particularly neoplastic, have been described. Recently, post-radiation gliomas have been reported.Methods The authors review 88 cases of cerebral glioma following radiotherapy in patients operated for neoplasms of the nervous system, including 6 personal cases of post-radiation gliomas treated in the Neurosurgical Division of the Department of Neurological Sciences, “La Sapienza” University, Rome. The criteria used to define this unusual pathologic association are discussed.Results There was a male predominance. Post-radiation gliomas were particularly malignant, the average dose was 33 Gy, and average free latency was 9.6 years. The first disease was most frequently acute lymphatic leukemia.Conclusions Post-radiation gliomas have particular features but do not present a histologic or clinical behavior different from analogous spontaneous gliomas. The fact that 88 cases have been reported in recent years suggests that a thorough biological, clinical studies be carried out on this association.

We report 3 cases of possible radiation-induced schwannomas observed in our Department. Their salient clinical and pathogenetic features are analyzed and the role of radiation therapy in the oncogenesis of these lesions is discussed. Several cases of radiation-induced tumors, including some of the nervous system, have been reported, but schwannomas have only occasionally been reported in connection with ionizing radiation. The possible adjuvant role of antineoplastic drugs is also discussed, and the literature on this topic is reviewed.

The case of a 50-year-old woman with cerebral meningioma and concomitant parathyroid adenoma and papillary thyroid carcinoma is presented. She complained of neurological symptoms characterized by right hemiparesis and dysarthria. Cerebral CT and MRI scans revealed a left voluminous frontal parasagittal lesion with the characteristics of a meningioma. Routine laboratory analysis revealed altered values of calcium-phosphorus metabolism. Intravenous infusion of saline solution at 0.9% of NaCI resulted in a reduction of serum ionized calcium. A left craniotomy was performed and a fibroblastic meningioma of 5 cm in diameter was removed. Even though the patient's clinical condition was good, a calcium-phosphorus metabolism test confirmed high plasma levels of ionized calcium and parathyroid hormone. Thyroid and parathyroid ultrasonography revealed multinodular goiter and a parathyroid lesion confirmed by 99mTc-TCO4/99mTc-MIBI scintigraphy. A left superior parathyroidectomy and total thyroidectomy were performed. Histological examination revealed a parathyroid adenoma and a small papillary carcinoma of 0.4 cm in the right thyroid lobe. As far as we know, this patient is the third case of meningioma associated with parathyroid adenoma and papillary thyroid carcinoma described in the literature.

Brain metastases from renal carcinoma may appear even a long time after surgical treatment of the primary tumor. The authors present 2 series of patients, one of which has already been published and the other new, for a total of 4 cases of brain metastasis from renal carcinoma with late onset, which occurred 13, 17, 26 and 12 years after primary surgical treatment. The other cases described in the literature were also critically reviewed.

The authors present 20 cases of likely post-traumatic intracranial meningiomas selected according to the conditions specified in the relevant literature. The relationship between head injury and subsequent development of meningioma remains a controversial and fascinating subject. The etiopathogenetic mechanisms and clinical features of our patients and those of the literature are discussed.

Nine patients with diagnosed breast cancer who developed meningiomas are reported. Articles suggesting that an association of these two tumors is possible. Some authors have noted hormonal sensivity and the presence of hormonal receptors in some meningiomas. Since breast cancer is the most common tumor in women, an association between it and meningiomas might be fortuitous. However, it is important to fully investigate brain lesions in patients with breast cancer so that potentially curable meningiomas are not considered as metastases.

Aims and background Metastasis to the brain from prostate carcinoma is a rare event; it is reported in less than 4% of postmortem examinations. The prevalence of cases detected antemortem is even smaller, and the prevalence of brain stem metastasis as the only site of metastasis has been reported in only two other cases.Method The authors present a third such case.Results A 55-year-old man, treated for an adenocarcinoma of the prostate (prostatectomy and radiotherapy), started to complain of facial expression disturbances and headaches 2 years later. Physicial examination showed a left VII cranial nerve palsy. MRI showed an enhancing mass in the pons. Total body CT was negative. The patient was treated with a course of whole-brain and brain stem radiotherapy following stereotactic biopsy. Four months after radiotherapy, the neurological symptoms had disappeared and the patient died of a myocardial infarct. The systemic disease was still clinically silent.Conclusion Our case involved only brain stem metastasis, probably implicating Batson's direct route of the paravertebral venous pathway.

Twenty-nine cases of single cerebral metastases from renal carcinoma were the object of a retrospective and prospective study covering a period of 15 years (1975–1988). The best diagnostic means were NMR imaging with paramagnetic contrast medium and CAT scans after intravenous injection of a double dose of contrast medium. All patients underwent total surgical removal of the cerebral lesion. Radiotherapy was useful but had less influence on further reproduction than in metastases from tumors of other sites. The median survival was 28.1 months in patients who received radiotherapy and 23 months in the others. No significant difference in survival was found between the group of patients with unknown primary tumors and the other group with diagnosed primary neoplastic disease.

Thirty-four breast cancer patients with single brain metastases were reviewed: 9 underwent surgical removal only and 25 surgical removal and radiotherapy. A longer survival was seen in patients who underwent surgical removal and radiotherapy, with a mean survival of 28 months. In the 9 patients who did not receive whole brain radiotherapy, the mean survival was 15 months and there was an higher frequency of brain relapse.

Aims and background Although systemic metastases from thyroid cancer are relatively frequent, they rarely affect the nervous system and only exceptionally originate from well-differentiated carcinoma.Methods The authors describe 6 cases of solitary brain metastases from thyroid carcinoma, well-differentiated in 3 cases and anaplastic in the other 3 cases.Results Four patients were females and 2 males (M:F ratio, 1:2); average age was 51 yrs (range 48-56). On average, the interval between diagnosis of the thyroid tumor and appearance of the metastasis was 2.8 years (range 1-12 years) and was shorter in the anaplastic forms (1.2 versus 4.4 years). Average survival was 15 months (range 6-48 months); in particular, average survival was longer in patients with well-differentiated carcinoma (9 vs 21 months) as also in those who did not present other metastatic sites (6 vs 24 months). Death was due to systemic progression of the disease in 4 cases and to brain-relapse in the other 2 cases.Conclusions Surgery, radioactive iodine (where uptake is demonstrable), and radiotherapy are the main therapies available for metastases from thyroid carcinoma. However, survival of patients appears to be modified by the type of treatment performed.
