Results of the proton magnetic resonance spectroscopy carried out on normal, benign breast disease and locally advanced breast cancer patients are presented. The in-vivo MR spectra of malignant breast tissue of patients (n = 67) suffering from infiltrating ductal carcinoma are dominated by the water resonance, while the spectra of the unaffected contralateral breast tissue of these patients are mainly dominated by resonance arising from lipids which is similar to the spectra of normal breast tissue obtained from volunteers (controls, n = 16). In addition to the water and lipid peaks, in majority of the patients (∼80%) the water suppressed spectra showed a resonance at 3.2 ppm due to choline containing compounds (TCho) before treatment. In patients receiving neoadjuvant chemotherapy, absence/reduction in choline was observed in 89% of the patients. TCho was also observed in 2 of 14 benign lesions. The sensitivity and specificity of in-vivo MRS in detecting TCho in malignant tumours was 78% and 86%, respectively. Observation of TCho before treatment and its disappearance (or reduction) after treatment may be a useful indicator of response of locally advanced breast cancer to neoadjuvant chemotherapy.

The study was undertaken to evaluate physical, psychological and functional aspects in quality of life (QoL) assessment prospectively in biopsy-proven head and neck cancer patients receiving radical radiotherapy. Fifty male patients were assessed using Karnofsky‘s Performance Status (KPS), Beck‘s Depression Inventory (BDI) and the Functional Living Index – Cancer (FLIC). Patient questionnaires were completed before radiotherapy, during 3–4 weeks of radiotherapy and 3 months after radiotherapy. Before the start of radiotherapy, KPS was 91±10.26, FLIC was 129.98±33.41 and BDI was 7.10±4.57. This indicated good performance and functional status with lower depression. In weeks 3–4 of radiotherapy, KPS (71.00±20.12) and FLIC (81.34±45.23) decreased, while BDI(16.56 ±9.01) increased, indicating impairment in QoL. Three months after radiotherapy, KPS (78.37±23.0), FLIC (119.51± 43.62) and BDI(9.02±7.81) improved but were not restored to pre-treatment levels. When patients were scheduled for radical radiotherapy, maximum deterioration in QoL was seen in weeks 3–4. This is the time when maximum supportive care and psychologic counselling is required.

Background:Spinal cord tumors are rare and fortunately affect only a minority of the population. These tumors are classified based on their anatomic location in relation to the dura mater and spinal cord as epidural, intradural extramedullary or intradural intramedullary. Intradural extramedullary Ewing's sarcoma is extremely rare.Purpose:Here, we are reporting a case of intradural extramedullary Ewing's sarcoma. This is the fourth such case to be reported in English literature.Methods:A 26-year-old gentleman presented to us with low backache and progressive paraparesis from a spinal tumor. Magnetic resonance imaging showed multiple intradural, extramedullary mass lesions extending from the T11 to S2 level. Neither osteolytic nor osteosclerotic changes were seen in the vertebral bodies. Extraskeletal Ewing's sarcoma was diagnosed histopathologically. He was treated by surgery, local radiotherapy and chemotherapy. Two months after treatment, he developed a new skip lesion in the spine at T6–T7 level. The new lesion was treated with local radiotherapy and chemotherapy.Results:Presently, the patient has completed treatment and is clinically doing fine.Conclusion:Intradural extramedullary Ewing's sarcoma is a rare aggressive neoplasm with high propensity for skip metastasis.Spinal Cord (2008) 46, 582–584; doi:10.1038/sc.2008.8; published online 12 February 2008 [ABSTRACT FROM AUTHOR]
