RESUMO

PURPOSE: The objectives of this study were to evaluate local disease control, overall survival (OS), disease-free survival (DFS) and local relapse-free survival (LRFS) in patients with endometrial cancer undergoing adjuvant vaginal brachytherapy (VBT )± external-beam radiotherapy (EBRT). MATERIALS AND METHODS: From September 2007 to February 2011, 40 patients with endometrial cancer were retrospectively analysed. Surgery consisted of total hysterectomy and bilateral salpingo-oophorectomy without node dissection (16 patients) or with bilateral pelvic node dissection (24 patients). The stage distribution was as follows: two IA, nine IB, 12 IC, five IIA, eight IIB, two IIIA and two IIIC. Thirty-four patients underwent EBRT and VBT. Six patients received VBT alone. RESULTS: Median follow-up was 26 months. The 5-year OS and DFS were 96.4% and 86.9%, respectively. No local recurrence was observed. Four patients presented distant disease (three had lung metastases and one had hepatic node metastases). Acute EBRT-related toxicities were seen in 15 (38%) patients. We recorded late toxicities in 14 patients (35%). There was no evidence of grade 3-4 toxicity. CONCLUSIONS: Adjuvant EBRT and/or VBT in patients with endometrial cancer showed good outcomes in terms of local disease control, with an acceptable toxicity profile.

RESUMO

PURPOSE: Our aim was to retrospectively analyse a series of patients with anal cancer treated with curative intent at a single institute in terms of survival and local disease control. MATERIALS AND METHODS: Forty-two patients with anal cancer were treated with primary radiotherapy with or without concurrent chemotherapy. The influence of the prognostic factors on overall (OS), disease-free (DFS), disease-specific (DSS), colostomy-free (CFS) and metastasis-free (MFS) survival was evaluated. RESULTS: Nine patients had stage I, 15 stage II, four stage IIIA and 14 stage IIIB disease. Tumour progression/ persistence occurred in five patients (12%). The 5-year OS, DSS, DFS, CFS and MFS were 72.7%, 84.2%, 85.7%, 81.1% and 87.1%, respectively. On univariate analysis, T stage emerged as highly significant for OS, DSS, CFS and DFS, whereas N status was a significant prognostic factor for DSS. On multivariate analysis, T stage was a significant prognostic factor for OS and CFS. CONCLUSIONS: Our data support the view that combined chemoradiation treatment of anal cancer is feasible and may provide survival benefits with an acceptable rate of adverse effects. We should consider T and N stages as important prognostic factors for survival.

RESUMO

Radiotherapy (RT) is often employed in patients with acromegaly refractory to medical and/or surgical interventions in order to prevent tumour regrowth and normalize elevated GH and IGF-I levels. It achieves tumour control and hormone normalization up to 90% and 70% of patients at 10-15 years. Despite the excellent tumour control, conventional RT is associated with a potential risk of developing late toxicity, especially hypopituitarism, and its role in the management of patients with GH-secreting pituitary adenomas remains a matter of debate. Stereotactic techniques have been developed with the aim to deliver more localized irradiation and minimize the long-term consequences of treatment, while improving its efficacy. Stereotactic irradiation can be given in a single dose as stereotactic radiosurgery (SRS) or in multiple doses as fractionated stereotactic radiotherapy (FSRT). We have reviewed the recent published literature on stereotactic techniques for GH-secreting pituitary tumors with the aim to define the efficacy and potential adverse effects of each of these techniques.

RESUMO

PURPOSE: The authors report acute toxicity in 14 patients with locally advanced head and neck squamous cell carcinoma treated with radiotherapy and cetuximab. MATERIALS AND METHODS: Data collection was performed prospectively on patients treated from September 2007 to March 2009. Treatment consisted of 64.8-70 Gy radiotherapy in conventional fractions and cetuximab. RESULTS: Two out of 14 patients did not complete the planned combined treatment; radiotherapy was temporarily suspended in six other patients. Seven of 12 patients received cetuximab until the end of radiotherapy. Treatment breaks were principally due to severe acute cutaneous or mucous toxicity. Any grade acneiform rash occurred in all patients. In-field G3-4 cutaneous toxicity occurred in five (36%) patients and G3-4 mucous toxicity in seven (50%). One patient died of sepsis. CONCLUSIONS: In our experience, severe acute toxic reactions are common in patients treated with radiotherapy and concurrent cetuximab, resulting in frequent breaks or incomplete treatment with potential reduction in disease control.

RESUMO

Epigenetic silencing of the O(6)-methylguanine-DNA-methyltransferase (MGMT) gene by promoter methylation is correlated with improved progression-free survival (PFS) and overall survival (OS) in adult patients with newly diagnosed glioblastoma multiforme (GBM) who receive alkylating agents. The aim of this study is to determine the correlation between MGMT and survival in elderly patients with GBM treated with radiotherapy (RT) and temozolomide (TMZ). Eighty-three patients aged 70 years or older with histologically confirmed GBM treated with RT plus TMZ between February 2005 and September 2009 were investigated in this study. The methylation status of the MGMT promoter was determined by polymerase chain reaction analysis. Median PFS and OS were 7.5 and 12.8 months, respectively. The MGMT promoter was methylated in 42 patients (50.6%) and unmethylated in 41 patients (49.4%). Median OS was 15.3 months in methylated patients and 10.2 months in unmethylated patients (P = 0.0001). Median PFS was 10.5 months in methylated tumors and 5.5 months in unmethylated tumors (P = 0.0001). On multivariate analysis MGMT methylation status emerged as the strongest independent prognostic factor for OS and PFS (P = 0.004 and P = 0.005, respectively). The results of the present study suggest that MGMT methylation status might be an important prognostic factor associated with better OS and PFS in elderly patients with GBM treated with RT and TMZ.

RESUMO

To value the late genitourinary (GU) morbidity in men treated with a hypofractionated radiotherapy regimen for prostate cancer. Patients with intermediate risk factors according to D'Amico's criteria were selected. The hypofractionated schedule consisted of 15 fractions of 3.63 Gy delivered three times per week for a total dose of 54.3 Gy. Significant changes in storage-symptoms were not found. A significant transient worsening in the score of late effects of normal tissue late effects normal tissue task force (LENT)-subjective, objective, management, analytic (SOMA) urinary-function domain was observed at 12 months with subsequent improvement at 28 months. The assessment of voiding-symptoms and maximum urinary flow rate (Qmax) showed that no significant difference was measurable at 12 and 28 months. For PVR, a transient increase at 12 months with a subsequent decrease at 28 months was measured. No significant increase in alpha-blockers usage and in the percentage of men with pathological nonintubated uroflowmetry (NIF) was observed at 12 and 28 months. Finally, patients did not perceive any clinical worsening in their quality of life (QoL) as attested by the International Prostate Symptom Score (IPSS)-QoL. Our study seems to suggest that our hypofractionated radiotherapy schedule for the treatment of prostate cancer is safe in terms of late urinary morbidity. Further study will be required to confirm our results.

RESUMO

OBJECTIVES: The optimal treatment for elderly patients (age >70 years) with glioblastoma (GBM) remains controversial. We conducted a prospective trial in 43 consecutive elderly patients with GBM treated with hypofractionated radiotherapy (RT) followed by adjuvant temozolomide. PATIENTS AND METHODS: Forty-three patients 70 years of age or older with a newly diagnosed GBM and a Karnofsky performance status (KPS) > or = 60 were treated with hypofractionated RT (6 fractions of 5 Gy each for a total of 30 Gy over 2 weeks) followed by up to 12 cycles of adjuvant temozolomide (150-200 mg/m(2) for 5 days during each 28 day cycle). The HRQOL was assessed with the EORTC Quality of Life Questionnaire C30. The primary endpoint was overall survival (OS). Secondary endpoints included progression free survival (PFS), toxicity and quality of life. RESULTS: The median OS was 9.3 months and the median PFS was 6.3 months. The 6 and 12 month survival rates were 86% and 35%, respectively. The 6 and 12 month PFS rates were 55% and 12%, respectively. In multivariate analysis KPS was the only significant independent predictive factor of survival (P = 0.008). Neurological deterioration occurred during or after RT in 16% of patients and was resolved in most cases with the use of steroids. Grade 3-4 hematologic toxicity occurred in 28% of patients during the adjuvant chemotherapy treatment with temozolomide. The treatment had no negative effect on HRQOL, however, fatigue (P = 0.02) and constipation (P = 0.01) scales worsened over time. CONCLUSIONS: Hypofractionated RT followed by temozolomide may provide survival benefit maintaining a good quality of life in elderly patients with GBM. It may represent a reasonable therapeutic approach especially in patients with less favourably prognostic factors.

RESUMO

OBJECTIVES: The optimal treatment for elderly patients (age > 70 years) with glioblastoma remains controversial. We conducted a prospective trial in 32 consecutive elderly patients with glioblastoma who underwent surgery followed by radiotherapy (RT) plus concomitant and adjuvant temozolomide. PATIENTS AND METHODS: 32 patients 70 years of age or older with a newly diagnosed glioblastoma and a Karnofsky performance status (KPS) > or = 70 were treated with RT (daily fractions of 2 Gy for a total of 60 Gy) plus temozolomide at the dose of 75 mg/m(2) per day followed by six cycles of adjuvant temozolomide (150-200 mg/m(2) for 5 days during each 28-day cycle). The primary endpoint was overall survival (OS). Secondary endpoints included progression free survival (PFS) and toxicity. RESULTS: The median OS was 10.6 months and the median PFS was 7 months. The 6-month and 12-month survival rates were 91% and 37%, respectively. The 6-month and 12-month PFS rates were 56% and 16%, respectively. In multivariate analysis KPS was the only significant independent predictive factor of survival (P = 0.01). Adverse effects were mainly represented by neurotoxicity (40%), which resolved in most cases with the use of steroids, and Grade 3-4 hematologic toxicity in 28% of patients. Chemotherapy was stopped in 2 patients, delayed in 9 patients and reduced in 4 patients. CONCLUSIONS: Standard RT plus concomitant and adjuvant temozolomide is a feasible treatment for elderly patients with newly diagnosed glioblastoma who present with good prognostic factors.

RESUMO

BACKGROUND: A randomized trial was conducted to determine (a) the role of radiotherapy and chemotherapy on local control and (b) to determine the timing of radiotherapy for early-stage breast cancer. MATERIALS AND METHODS: Five hundred and ninety patients were treated with both conservative surgery and radiotherapy (group A). The average time interval between surgery and radiation was 90 days for 452 patients and over 90 days for 138 patients. One hundred and ninety-four patients underwent adjuvant therapy based on CMF regimens (group B). RESULTS: Among 396 patients of group A, 8.1% had local failure; we observed 7.2% local recurrences in 363 patients who received therapy before 90 days and 18.2% in patients who received therapy after 90 days. Among patients of group B, 7.7% had local failure; for patients who underwent radiotherapy before 90 days, the local recurrence rate was 6.6%, compared with 12.3% for patients who underwent therapy more than 90 days after surgery. CONCLUSION: In patients who are eligible to receive chemotherapy, it is possible to administer radiotherapy after systemic treatment, while in patients who have to be treated with radiotherapy more then 90 days after breast surgery, chemotherapy can reduce the local failure rate.

RESUMO

AIMS: To assess the utility of 99mTc tetrofosmin (TF) scintigraphy as a diagnostic modality in lymphomas. METHODS: Seventeen patients (14 with Hodgkin's disease and three with non-Hodgkin's lymphomas; age range, 10-59 years) were investigated. Planar and SPECT images of the supradiaphragmatic region (including neck and chest) were obtained. All patients were untreated at the time of the first scintigraphy. Follow-up scans after therapy were acquired in six patients (in five twice), so a total of 28 scintigraphic studies were performed. Mediastinal, pulmonary, cervical, supraclavicular and axillary activity was evaluated and results were compared in a blinded fashion with those of CT. RESULTS: TF imaging demonstrated pathological focal uptake at 38 sites (16 in the mediastinum, eight in the lungs, four in the axillae, eight in the supraclavicular region and two in the cervical region) in 16 of 17 untreated patients. CT identified 24 lesions (16 in the mediastinum, two in the lungs, two in the axillae, two in the supraclavicular and two in the cervical region) in 17 patients. Scintigraphy detected 22 of the 24 lesions demonstrated by CT and revealed 16 unknown tumor sites in 10 patients. The only negative pre-treatment scintigraphy result was found in a patient with axillary lymph node involvement. On the first post-treatment scintigrams there was a reduction in the number of visualized pathological sites (seven vs 16) in five of the six patients examined. The second follow-up study demonstrated only two lesions in two of the five patients examined. CONCLUSIONS: Our preliminary results indicate that TF imaging is effective in depicting supradiaphragmatic lymphoma lesions in untreated patients and suggest that serial scintigraphic studies may be suitable for monitoring response to treatment. However, larger series are needed to better define the possible role of TF scintigraphy in the follow-up of the response to therapy.

RESUMO

The lymphoid tissues of Waldeyer's ring, including the nasopharynx, are rarely involved in Hodgkin's disease (HD). Between March 1977 and July 2001, about 2150 patients affected by HD were observed in our institute; 7 of them (0.32%), all male patients, had HD of the nasopharynx. They had no symptoms and blood tests were normal. All patients were treated with chemotherapy and/or radiotherapy and achieved complete remission. At a median follow-up of 72 months, they are alive and in continuous complete remission. We conclude that Hodgkin's disease of the nasopharynx is a rare and predominantly male disease with a particularly favorable prognosis. Bone marrow biopsy could be avoided. We believe that two to four cycles of a chemotherapeutic regimen and involved field radiotherapy at an intermediate-high dosage (25-30 Gy) could be the first line treatment for these patients.

RESUMO

BACKGROUND AND OBJECTIVES: In order to draw attention not only to patients affected by a neoplasia, but also to those who may have problems of sterility, we describe six women affected by Hodgkin's disease who had precocious menopause due to chemotherapy and/or radiotherapy but who were safely delivered of children. These pregnancies were achieved through oocyte donation, in vitro fertilization and intrauterine embryo transfer or oocyte intracytoplasmic insemination. DESIGN AND METHODS: During natural or iatrogenic menopause, the uterus preserves its capacity to respond to steroidal hormones and to permit implantation and development of an embryo. Our study concerns six young females with iatrogenic menopause caused by treatment of Hodgkin's disease who carried a pregnancy to term. The pregnancies were achieved by oocyte donation, in vitro fertilization and intrauterine embryo transfer or oocyte intracytoplasmic insemination. Endometrial maturation was obtained by administration of estradiol and progesterone. Steroidal therapy was administered until the 13th-14th week in relation to placental function. RESULTS: Five of the 6 females underwent Caesarean section because of a twin birth or complications during the third trimester of pregnancy (gestosis). All the delivered children are, to date, well; their median age is 4 years. INTERPRETATION AND CONCLUSIONS: This study confirms the possibility of women treated for Hodgkin's disease being able to carry a pregnancy safely to term with the help of steroidal therapy. Careful clinical and obstetric surveillance is important. Focusing attention on long-term survivors of Hodgkin's disease, we set the goal of improving the quality of life of these patients, considering their psychophysical well-being as a whole. Greater attention to the problems of safeguarding fertility in these patients would be advisable, also in the light of legislative regulation of medical care techniques in various countries.

RESUMO

BACKGROUND AND OBJECTIVE: Patients treated for Hodgkin's disease have an increased risk of developing subsequent acute leukemia. This co-operative study was conducted to assess the relative risk associated with several candidate factors including age, splenectomy, combined modality therapy and cumulative drug dose including alkylating agents and nitrosurea derivatives. DESIGN AND METHODS: This study evaluated the risk of acute leukemia according to pretreatment variables and therapy modalities among 1659 patients treated for Hodgkin's disease and followed for a median time of 10 years. Both case-control and actuarial risk studies were performed. Median age was 34 years (range: 12-83); 53% of patients were splenectomized. As to the overall therapy, 348 patients (21%) were given radiotherapy (RT) alone, 375 (23%) chemotherapy (CT) alone (including MOPP, MOPP + ABVD or MOPP + ABVD + lomustine); 936 (56%) received both CT and RT, either as primary or salvage treatment. RESULTS: The overall 15-year actuarial risk of leukemia was 4.2%; the hazard function curve showed two peaks of risk at the 3th and the 8th year from the initiation of therapy and no leukemia beyond the 12th year of follow-up. Risk of leukemia was 0.3% after RT alone, 2.8% after CT alone (2.2% after MOPP; 4.4% after MOPP + ABVD + lomustine), and 5.4% in patients given combined modality therapy (10.2% for RT + MOPP; 15.6% for RT + MOPP + lomustine). No leukemia occurred after ABVD alone and the risk was low (0.6%) when neither mechlorethamine nor lomustine were utilized. Patients who had received extended radiotherapy including abdomen and pelvis in addition to MOPP showed a significantly higher risk of leukemia compared to those given limited RT + MOPP (P = 0.01). Case-control analysis indicated advanced stage, type and duration (> 8 months) of CT and extension of RT as significant risk factors for leukemia. Compared to RT alone, the odds ratio was 5.9 after MOPP + extended RT, and 8 when a lomustine-containing regimen was used, as well. Neither age nor splenectomy were independent risk factors for leukemia; splenectomy was influential only when patients had been given MOPP chemotherapy, as well. INTERPRETATIONS AND CONCLUSIONS: Both case-control and actuarial analyses indicated that: a) combined modality therapy with MOPP and extensive RT (including abdomen and pelvis), and the use of lomustine added to the leukemogenic risk of MOPP alone; b) programs without mechlorethamine, procarbazine and lomustine were almost devoid of leukemogenic risk.

RESUMO

January, 1992, to October, 1995, sixty-four patients with advanced head and neck carcinoma were submitted to reconstructive surgery using pedunculated myocutaneous or revascularized flaps and then to CT and MRI. Myocutaneous flaps were used in 26 cases--12 tubular and 14 linear flaps--and revascularized flaps in 38--14 latissimus dorsi flaps, 12 temporal flaps, 7 jejunal flaps and 5 radial flaps. Twenty-six of 64 cases (41%) relapsed: MRI correctly depicted the recurrence in 24 cases and CT in 19, with 2 false positives and 2 false negatives at MRI and 6 false positives and 7 false negatives at CT. The sensitivity, specificity, accuracy, positive and negative predictive value of CT were 84%, 78%, 73%, 76% and 82%, respectively, while the corresponding MR rates were 95%, 94%, 92%, 92% and 95%. MRI was more accurate than CT in demonstrating postoperative and postirradiation changes (92% for MRI versus 73% for CT) thanks to its higher sensitivity in depicting tumor tissue on T2-weighted and post-Gd-DTPA images. CT is very useful in the early postoperative period, to follow-up poorly collaborative patients, because its acquisition time is short; MRI should be performed when CT findings are questionable and the revascularized flap is used to repair a large defect at the skull base.

RESUMO

January, 1992, to October, 1995, sixty-four patients with advanced head and neck cancer underwent head and neck reconstructive surgery using myocutaneous or revascularized flaps; in the same period, all patients were consecutively examined with CT and MRI. Myocutaneous flaps wer used in 26 patients: 12 flaps were tubular and 14 linear. Revascularized flaps were used in 38 patients: to repair a large defect in 26 patients (14 latissimus dorsi flaps and 12 temporal muscle flaps) and to repair an oral damage in 12 patients (5 revascularized radial and 7 jejunal flaps). CT and MR images of myocutaneous flaps showed the flaps as fatty areas, repairing large surgical defects, hypodense at CT and hyperintense at MRI, with no post-contrast enhancement. The postoperative scar around the flap exhibited soft-tissue density with slight post-contrast enhancement at CT and slightly hypodense on T2-weighted MR images. Post-contrast CT and MRI showed slight scar enhancement with no signal changes in the fatty component. The appearance of revascularized flaps at CT and MRI depends on the characteristics of the structure used to repair the surgical defect: jejunal and radial flaps appeared as mostly fatty thickened layers with both imaging methods. Temporal and latissimus dorsi flaps are made basically of muscular tissue, fatty tissue and occasionally skin (used to repair a mucosal defect): consequently, CT showed a structure with mostly parenchymal density in all cases and MRI depicted intermediate signal intensity. MRI was useful to detect 12 revascularized jejunal or radial flaps thanks to its higher contrast resolution and multiplanar capabilities showing even such thin structures as these flaps. Moreover, MRI permitted to study skull base reconstruction with revascularized (latissimus dorsi) flaps in 5 of our patients.

RESUMO

This study was undertaken to examine the influence of various factors on the occurrence of acute nonlymphocytic leukemia (ANLL) in a group of longterm survivors of Hodgkin's disease (HD). From 1972 to 1992, 1045 patients with HD were assessed and treated at the Department of Radiation Oncology, the Institute of Radiology, and the Department of Human Biopathology, Hematology Section, University of Rome "La Sapienza". The average follow-up was 72 months. For a more accurate calculation of the risk of ANLL occurrence, the patients were first divided into three subgroups according to initial treatment and then according to the total treatment they had received. Moreover, to establish the probable connection between leukemia and splenic treatment the patients were also divided into three subgroups (splenectomy, splenic irradiation, and no splenectomy/no splenic irradiation). Sixteen cases of ANLL were recorded, giving an overall risk of 0.2% at 5 years and 3.4% at 20 years. In 12 patients overt leukemia was preceded by a myelodys-plastic syndrome. Five cases had evaluable chromosome analysis. Clonal chromosome abnormalities were demonstrated in two patients, whereas three patients showed an apparently normal karyotype. Bone marrow agar cultures were analyzed in two patients and were abnormal in both cases. In the radiotherapy (RT) group, the cumulative risk was 0.4% at 10 years and 3.2% at 15 and 20 years: in the chemotherapy (CT) group it was 1.2% at 10, 15, and 20 years; in the combined group it was 3.7% at 10 years and 4.9% at 15 and 20 years. In the multivariate analysis, MOPP treatment with or without RT is a statistically significant variable for ANLL occurrence (p = 0.009). This study demonstrates that splenic treatment does not lead to ANLL. Treatment with MOPP alone and with MOPP plus RT can increase the risk of ANLL.

RESUMO

BACKGROUND AND OBJECTIVE: This study examines the occurrence of solid tumor (ST) in relation to the different types of therapy (radiotherapy, chemotherapy and radiochemotherapy; splenectomy or splenic irradiation vs no splenectomy-no splenic irradiation) received by patients treated for Hodgkin's disease (HD). METHODS: The study included 1,045 HD patients treated at the Department of Radiation Oncology, the Institute of Radiology and the Department of Human Biopathology, Hematology Section, University of Rome, "La Sapienza", from 1972 to 1992. For 23% of the patients the follow-up period was longer than 10 years. The average follow-up period was 72 months. For a more accurate calculation of the risk of ST occurrence, the patients were first divided into 3 subgroups according to initial treatment and then according to the total treatment they had received. Moreover, to establish a probable connection between solid tumor and splenic treatment the patients were also divided into 3 subgroups (splenectomy, splenic irradiation and no splenectomy/no splenic irradiation). RESULTS: We recorded twenty-four cases of ST after initial treatment. Secondary solid tumor showed a cumulative risk of 0.2% and 13.4% at 5 and 20 years, respectively. After initial treatment with radiotherapy (RT) alone, the cumulative risk was 1.7% and 5.2% at 10 and 20 years, respectively; in the chemotherapy (CT) group, it was 2.4% and 18.1%; in the CT(+)RT group, it was 1.7% and 9%. No statistically significant differences were observed among the different types of treatment (splenectomy, splenic irradiation or no splenectomy/no splenic irradiation) as regards the occurrence of ST. According to multivariate analysis, the most important factor in the risk of ST was age (> 40). Relative risk was 5.2, p = 0.0001. INTERPRETATION AND CONCLUSIONS: We conclude that an age of over 40 at diagnosis and treatment with CT alone greatly increase the risk of solid tumor occurrence.

RESUMO

Preoperative MR staging in 34 patients with gastric adenocarcinoma was compared with postoperative histologic findings to evaluate MR sensitivity, specificity and accuracy. MR exams were carried out with an 0.5-T superconductive magnet, with SE T1- and T2-weighted sequences on axial and sagittal planes, 10-mm slice thickness and 3-mm interval. The stomach was distended with a watery solution of Gd-DTPA. MRI showed the tumors only in their advanced stage. MR sensitivity was high in detecting hepatic metastases, but peritoneal carcinomatosis was difficult to demonstrate because of inherent technical MR limitations, such as motion and respiratory artifacts. MRI had 40.6% sensitivity, 93.87% specificity and 42.08% accuracy in demonstrating lymph node involvement. Hepatoduodenal lymph nodes were particularly difficult to study, as were those in the splenic hilum and artery. No correlation was found between tumor invasion and lymph node size. MRI exhibits many limitations in gastric carcinoma staging because of motion and respiratory artifacts and of the long acquisition times needed for gastric studies. However, MR sensitivity and specificity are similar to those of CT, as reported in the literature.

RESUMO

We report the case of a 21-year-old man in whom intracranial localization was discovered during initial staging at the onset of Hodgkin's disease (HD). The patient was treated by surgical excision, irradiation and chemotherapy and 50 months after completion of therapy is in remission with no evidence of HD. A brief review of the literature regarding 48 patients with intracranial Hodgkin's disease is presented.
