The objective of this study was to determine the efficacy of spinal MRI in suspected spinal metastasis. The effect of spinal MRI on treatment planning choices (radiation, chemotherapy, steroids, or surgery) in 130 patients with suspected spinal metastatic involvement was evaluated. In a retrospective group of 100 patients, 47 (47%) had therapy changes associated with MR findings. Forty out of 78 (51%) of patients presenting with symptoms (back pain, weakness, paresthesia, or sphincter dysfunction) had MR associated therapy choices. Seven out of 22 (32%) of patients without spinal symptoms had therapy changes. Twelve out of 30 (40%) of patients evaluated prospectively had therapy choices directed by MR findings. Overall, 59 out of 130 (45%) of patients had therapy choices associated with findings in spinal MRI. MRI results influenced the addition or modification of radiation therapy treatment in 33% of the patients suspected of metastatic disease to the spine.

Patients with colorectal carcinoma progressing after a 5-fluorouracil (5-FU)-containing regimen were eligible. One treatment cycle consisted of repeated administrations of 5-FU combined to folinic acid for six times and to oxaliplatin for three times over 50 days. 5-FU was given at the dose of 2.6 g/m2 as a continuous infusion over 24 h on days 1, 8, 22, 29 and 43 preceded by i.v. folinic acid (FA) at a dose of 500 mg/m2 over 1 h. Oxaliplatin was given 1 h after 5-FU at the dose of 130 mg/m2 over a 2 h infusion on days 1, 22 and 43. A total of 37 patients were treated according to this schedule. The rates of objective responses after the first and second treatment cycles were 28 and 17%, respectively, with rates of tumor growth control, i.e. including the stabilizations, of 55 and 28%. The median duration of response was 10 months and the median duration of stabilizations was 6 months. The median survival time from initiation of oxaliplatin-containing therapy is 10 months (2-28+). The median survival time from the diagnosis of metastatic disease is 24 months (2-40+). The main toxicities were leucopenia, diarrhea, fatigue and paresthesias. The combination of 5-FU/FA/oxaliplatin was well tolerated and appears as a meaningful therapy after failure of a previous 5-FU-containing treatment.

For melanoma, in-transit metastases (ITMs) are a harbinger of systemic disease in over 70% of patients and thus warrant a systemic approach to management. In this study, previously untreated patients with ITMs (n=15) received a systemic regimen of 'CVD' in 21 day cycles (median, three cycles) as follows: dacarbazine 800 mg/m2 intravenously (i.v.) on day 1, vinblastine 1.6 mg/m2 i.v. on days 1-5, and cisplatin (CDDP) 100 mg/m2 by 24 h intra-arterial (i.a.) infusion in 1l of heparinized saline via the iliac or subclavian artery on day 3. There were three clinical complete responses (CRs) in patients with a modest burden of ITMs (< 3 cm in size) and seven partial responses (PRs), yielding a 67% response rate (95% confidence interval, 38-88%). One of the clinical CRs had microscopic residual disease at surgery (a pathological PR). The times to progression (TTP) for the CRs were 5, 21 and 38+ months; the median TTP for the PRs was 4.5 months (range, 2-10 months). Overall median survival was 31 months. Systemic toxicities were similar to those induced by i.v. CVD. However, patients noted more pronounced paraesthesia in the infused extremity. Also, two patients experienced severe CDDP-induced burns, one patient developed brachial plexopathy, and one patient had a haemorrhage in an occult brain metastasis. The high clinical activity of this regimen will have to be confirmed in more patients before a first-pass i.a. advantage can be claimed. Furthermore, the dose, schedule and technique of i.a. CDDP delivery must be further refined before it can be routinely incorporated in regimens as an alternative to isolated regional hyperthermic perfusion, which is technically more difficult and is not readily available in community-based hospitals.

Meningeal carcinomatosis occurs in 1%-5% of patients with breast cancer. Early diagnosis and aggressive treatment of neurologic involvement are important factors of prognosis. We report a case of a 52-year-old woman who was affected by bilateral breast carcinoma treated with surgery and chemotherapy. Six years after she had become asymptomatic, X-rays showed lumbar spine metastases which were treated with radiotherapy. After 1 year she began to suffer from lower limb paresthesias, unsteadiness and unstable gait. Clinical examination showed lower limb sensory ataxia with lack of knee and ankle reflexes, and hypopallesthesia from the iliac spine to the foot. Spinal magnetic resonance imaging (MRI) with contrast agent revealed no medullar compression. Electromyography disclosed bilateral involvement of L4-L5-S1 roots and corresponding paraspinal muscles. Sensory and motor conductions were normal. Cerebrospinal fluid (CSF) examination showed the presence of neoplastic cells, confirming the diagnosis of meningeal carcinomatosis. Our patient underwent 9 cycles of intrathecal methotrexate therapy (25 mg/cycle) with improvement of ataxia and relief of paresthesias. One year later, CSF examination is still negative. We point out the importance of electrodiagnostic studies and CSF examination in the early documentation of root involvement in cancer patients, when computed tomography, MRI and myelography are normal. Early diagnosis may lead to effective therapy which prolongs survival.

The members of four generations of a family with Von Hippel-Lindau syndrome (VHL) have been followed by one of us (I.P.) for 30 years. The disease was proved in four members of this family, in three of them associated with pheochromocytoma. The grandmother (I-1) died at the age of 16 years two months after her first birth. The cause of death was not established. Her daughter (II-1) had 9 births with 5 children alive. Paresthesia and difficulties in walking followed by paraparesis and paraplegia were the first signs of the disease at the age of 58 years. The surgical treatment was performed because of an expansive lesion at the level of Th 3-4. Pathohistological examination was not done. It seems that a haemangioblastoma might be the cause of her disease. Diagnosis of pheochromocytoma was documented in a female patient (III-2) in 1972. Two years later she was successfully operated on. Pathohistological examination proved clinical diagnosis. She had also diabetes mellitus, cholelithiasis and cardiomyopathy. She died at the age of 56 years. A right-sided pheochromocytoma was diagnosed in a next female patient (III-4) at the age of 22 years. Her surgical treatment was successful. Retinal haemangioblastomatosis was established 7 years later in this patient. She was blind at the end of her life. Haemangioblastomatosis cerebelli was diagnosed soon, and she died at the age of 51 years. A 12- year old boy (IV-3) presented severe hypertension (36/24 kPa). Left-sided pheochromocytoma was removed in this patient one year later. Right-sided pheochromocytoma was operated on in the same patient at the age of 24 years. An elevated level of urinary dopamine was documented four years after the second operation. A malignant right-sided pheochromocytoma was operated on in the same patient 15 years later. At the same time metastases were found in the lower part of the right lung lobe. A 131-I-MIBG therapy could not be realized. He died at the age of 41. Pathohistological examinations proved the clinical diagnosis in this patient after all of three surgical treatments. MEN 2 syndrome was excluded by proper genetical analyses on the RET-protooncogen. Genetical analyses are in the course to identify the possible mutations of VHL-tumour-suppressor gene through the living members of the family. Multidisciplinary approach is mandatory in diagnosis, follow up and treatment of this specific group of patients. A collaboration among specialists of different fields of medicine (internal medicine, ophthalmology, neurology, radiology, urology, neurosurgery, biochemistry, pathology and genetics) is suggested.

The most important determinant of prognosis for patients with breast cancer is the status of the axillary lymph nodes. Axillary lymph node dissection (ALND) has been performed for over a century to stage the cancer, achieve regional control, and perhaps improve survival. In accordance with tradition, ALND has been performed on all patients with the diagnosis of invasive breast cancer. In the early 1990s, this dogma was challenged because of the significant morbidity associated with ALND (paresthesia, extremity lymphedema) and the fact that greater than 50% of all breast cancers are node negative. A less morbid but highly accurate staging procedure, lymphatic mapping and sentinel lymph node biopsy (SNB) was introduced. Currently, the de facto standard of care in breast cancer is to perform LM and SNB in patients with small tumors and clinically negative axilla. While numerous methodological issues are being raised, the utility of LM and SNB identification continues to expand. In the current review we assess the application of this technique to locally advanced breast cancer (LABC) and neoadjuvant chemotherapy. What role does SNB play in locally advanced disease? Is LM and SNB accurate for patients with advanced disease? What influence do axillary metastases have on further treatment? What is the role of SNB in the planning for neoadjuvant patients? The skillful management of patients with breast cancer lies in the delicate balance between maximizing the efficacy of treatment and minimizing its morbidity and failure.

A 27-year-old female presented with gait disturbance and left facial paresthesia. She had a history of breast and lung masses not yet identified. Magnetic resonance (MR) imaging revealed a tumor suggesting a petroclival meningioma. Her symptoms worsened rapidly. MR imaging showed enlargement of the tumor. Subtotal removal of the tumor was performed. Histological examination revealed metastatic adenocarcinoma. Examination of the other masses confirmed adenocarcinoma originating from lung carcinoma. Dural metastases can be difficult to preoperatively differentiate from meningioma clinically or radiographically. MR spectroscopy and laboratory examinations such as cytologic and serologic studies are valuable for differential diagnosis. The final diagnosis of the tumor depends on the histological findings. However, careful monitoring of the patient's course is very important to detect rapid growth of metastases.

Lymphatic mapping (LM) and sentinel lymph node biopsy (SLNB) have become widely accepted in the setting of breast conservation surgery. We hypothesized that LM can be extended to women undergoing total mastectomy, being technically feasible, yielding highly accurate and sensitive results, improving axillary staging, and reducing postoperative morbidity. Between 1995 and 2003, 99 women (mean age 59 years, range 34-87) underwent 100 mastectomies with LM using blue dye alone. Fifty-nine operations (60%) were followed by a completion axillary lymph node dissection (ALND). Ninety per cent of patients had invasive carcinoma; 10 per cent had in situ carcinoma. Mean tumor size was 2.5 cm (range 0.3-8 cm). One hundred fifty-nine sentinel nodes (SNs) (mean 1.65, range 1-5) were successfully identified in 96 (96%) axillae. Twenty-five (25%) sentinel nodes revealed nodal metastases. Five of 25 (20%) SNs had micrometasteses. Three patients had a false-negative SN, yielding a sensitivity of 91 per cent. The accuracy of LM was 97 per cent. No patient who underwent SLNB alone developed lymphedema, axillary seroma formation, infection, or restricted arm movement. This was contrasted with patients undergoing ALND, where 10 (16%) developed lymphedema and 2 (3%) developed an infection. Ten (25%) patients developed axillary paresthesias after SNB compared with 47 (78%) patients after ALND (P < 0.0001). LM in the setting of mastectomy is accurate and sensitive. This technique improves axillary staging and decreases morbidity. Patients who are not candidates for breast conservation should be offered LM and SLNB at the time of mastectomy.

Hemangiocytoma are rare malignant vascular tumor. Vertebral location is uncommun. They occur preferentially at the lumbo-sacrul spine with paravertebral extension. The features include spinal pains, para vertebral tumefaction and paresthesia. The CT and MRI scans can help to diagnosis which is histological. The treatment is surgical combined or no with radiotherapy. The pronostic is marqued by the recidive risk and metastases. We report a new case of vertebral hemangiopericytoma of the thoraco-lumbar spine with litteratur review.
