Activity of broad-spectrum T cells as treatment for AdV, EBV, CMV, BKV, and HHV6 infections after HSCT.

It remains difficult to treat the multiplicity of distinct viral infections that afflict immunocompromised patients. Adoptive transfer of virus-specific T cells (VSTs) can be safe and effective, but such cells have been complex to prepare and limited in antiviral range. We now demonstrate the feasibility and clinical utility of rapidly generated single-culture VSTs that recognize 12 immunogenic antigens from five viruses (Epstein-Barr virus, adenovirus, cytomegalovirus, BK virus, and human herpesvirus 6) that frequently cause disease in immunocompromised patients. When administered to 11 recipients of allogeneic transplants, 8 of whom had up to four active infections with the targeted viruses, these VSTs proved safe in all subjects and produced an overall 94% virological and clinical response rate that was sustained long-term.

Role and cost effectiveness of PET/CT in management of patients with cancer.

PET/CT is a relatively new imaging technology, whose undoubted advantages are valuable in clinical oncology as well as in all fields of diagnosis, staging, and treatment. The hardware combination of anatomy and function has been the true evolution in imaging. PET using 18F-fluorodeoxyglucose (FDG) is increasingly used for the staging of solid malignancies, including colon, lung, etc., but anatomic information is limited. Integrated PET/CT enables optimal anatomic delineation of PET findings and identification of FDG-negative lesions on computed tomography (CT) images and might improve preoperative staging. However, controversy still exists in relation to the application of PET/CT in clinical practice, mainly because of its high cost. It is evident that apart from additional costs, potential savings also are associated with PET/CT as a result of avoiding additional imaging examinations or invasive procedures and by helping clinicians make the optimum treatment decisions. The authors review the literature on the role of PET/CT in management of various tumors and discuss the medicoeconomic usefulness.

A phase II study of sequential docetaxel and gemcitabine followed by docetaxel and carboplatin as first-line therapy for non-small cell lung cancer.

Our study involves a preliminary phase II trial, which evaluates the activity, feasibility and tolerability of a sequential combination of docetaxel and gemcitabine followed by docetaxel and carboplatin, as first-line treatment for inoperable NSCLC. Twenty-six chemo-naïve patients aged less than 75 years with histologically or cytologically confirmed unresectable stage IIIB, IV or relapsed post-operative metastatic NSCLC were included in the study. Gemcitabine 1,250 mg/m(2) was administered and was followed by docetaxel 65 mg/m(2). Treatment was administered on days 1 and 14 in a 28-day cycle for three consecutive cycles. If patients had no progressive disease after three cycles of chemotherapy, they received another three cycles of docetaxel 65 mg/m(2) followed by carboplatin AUC5 on day 1 in a 21-day cycle. Recombinant human granocyte colony-stimulating factor (rhG-CSF) was given prophylactically. In addition, all patients received standard pre- and post- treatment with oral dexamethasone. Response rates at three cycles were: 19% achieved a partial response (PR), 46% had stable disease (SD) and 23% had progressive disease. At six cycles, 8% of the patients maintained PR, 19% showed SD and 35% had progressive disease. The median time-to-disease progression was 6 months. The median survival time of patients was 10 months while, at the end of the first year, the patients who managed to get through the complete therapy (20 patients) had a survival rate of 38%. This detailed analysis of 20 patients showed that 80% of the patients survived for up to 6 months, 38% up to 12 months and 19% for more than a year. The only risk factor associated with the hazard of death among the factors studied was the performance status of the patients. Patients with PS=0 presented a median survival time of 13 months and those with PS=1, it was only 9 months. Non-haematological and haematological toxic effects were generally mild to moderate and entirely manageable.

Metastatic cervical carcinoma to the thyroid gland: a case report and review of the literature.

Although metastases within the thyroid gland are rare, they are not as infrequent as generally believed. Asymptomatic breast, lung, and renal cell carcinomas may metastasize to the thyroid. When they become symptomatic, diagnosis relies upon fine needle aspiration cytology. We report the case of a squamous cell cervical cancer that presented metastatic lesions to the thyroid gland four years after the initial diagnosis. The procedures used to confirm the diagnosis, stage, and subsequently manage the patient are described. We present both a review of the necessary clinical investigation and the therapeutic options open to these patients. We conclude that patients who present swelling or palpable nodules in the thyroid side and have a history of a previous malignancy must be considered for metastatic disease.

Skin cancer in the elderly.

With the significant increase in the average life-span in the industrial world, skin cancer has become a great health concern. There are various epidemiological, biological and molecular data suggesting that skin cancer is predominantly a disease of the elderly, since approximately 53% of skin cancer-related deaths occur in persons more than 65 years old. With regard to the management of elderly patients with skin cancer, this should be individualized depending upon the clinical performance status, and age alone should not constitute an obstruction for the administration of the optimal treatment. Since elderly patients with melanoma have a worse prognosis, emphasis should be given to primary and secondary prevention. Physicians treating elderly patients should be trained in an individualized approach to these patients and encouraged to participate in programs for the early detection of suspicious skin lesions.
