The necessity of long-term venous access in cancer patients appears at frequent and long-term courses of cytotoxic therapy. Peripheral veins of forearms are most often used for these aims. The conditions of peripheral venous channel in 32 cancer patients, who underwent the long-term treatment with antitumor preparations were analyzed in the article on own investigatory material. The methods of dopplerography, morphological and immunohystochemical studies were used. The qualitative and quantitative dopplerographic changes in forearm veins in different terms after chemotherapy start were revealed in most patients. The conclusion was made about unsuitability of forearm peripheral veins for the long term administration of cytostatics and the necessity to create the alternative vascular access that would correspond to the criteria of safety, reliability and long-term exploitation.

A patient diagnosed with Borrmann type 4 gastric cancer (mucinous adenocarcinoma), who had refused surgery, was treated by oral administration of 1200 mg/day 5′-deoxy-5-fluorouridine for about 23 weeks. This resulted in substantial improvement of her condition, i.e. the tumour almost completely disappeared, distensibility improved between the central region of the corpus ventriculi and the angulus, and only small protrusions remained on the anterior and posterior walls and the pars pylorica of the lesser curvature. Mild anorexia and diarrhoea were noted as adverse reactions although these symptoms subsided by reducing the dose or temporarily stopping treatment, thereby allowing long-term treatment. Long-term use of 5′-deoxy-5-fluorouridine proved temporarily effective in this patient. The patient died about 3 years and 7 months after starting therapy. Examination showed that the cancer had been mainly in the stomach and that it had metastasized to the colon and pancreas. The liver was free of metastasis.

Background and Objective: There may be a possible link between the use of HAART and oxidative stress-related mitochondrial dysfunction in HIV patients. We evaluated the mitochondrial and oxidative impacts of short and long-term administration of HAART on HIV patients attending the Enugu State University Teaching (ESUT) Hospital, Enugu, Nigeria following short and long-term therapy. Methods: 96 patients categorized into four groups of 24 individuals were recruited for the study. Group 1 comprised of age-matched, apparently healthy, sero-negative individuals (the No HIV group); group 2 consisted of HIV sero-positive individuals who had not started any form of treatment (the Treatment naïve group). Individuals in group 3 were known HIV patients on HAART for less than one year (Short-term treatment group), while group 4 comprised of HIV patients on HAART for more than one year (Long-term treatment group). All patients were aged between 18 to 60 years and attended the HIV clinic at the time of the study. Determination of total antioxidant status (TAS in nmol/l), malondialdehyde (MDA in mmol/l), CD4+ count in cells/μl, and genomic studies were all done using standard operative procedures. Results: We found that the long-term treatment group had significantly raised the levels of MDA, as well as significantly diminished TAS compared to the Short-term treatment and No HIV groups (P<0.05). In addition, there was significantly elevated variation in the copy number of mitochondrial genes (mtDNA: D-loop, ATPase 8, TRNALEU uur) in the long-term treatment group. Interpretation and Conclusion: Long-term treatment with HAART increases oxidative stress and causes mitochondrial alterations in HIV patients.

This study was conducted to investigate whether hypertension induced by long-term in vivo administration of dexamethasone in rats could be prevented by the newly synthesized potent antiglucocorticoid drug RU 486. Subcutaneous implantation of 5 mg of dexamethasone pellets in Sprague-Dawley rats resulted in a rapid increase in the blood pressure that remained elevated during the 3 wk of experimental observation. RU 486 (50 mg) administered alone surprisingly showed slight elevation of blood pressure over untreated control animals. However, the blood pressure leveled off to control levels over the next 2 wk. Interestingly, a 50-mg RU 486 pellet implanted along with 5 mg of dexamethasone effectively prevented the dexamethasone-induced increase in blood pressure. RU 486 administered together with dexamethasone prevented dexamethasone-induced diuresis and urinary Na+ excretion. However, RU 486 was unable to reverse the weight loss or involution of thymus observed by long-term treatment with dexamethasone alone. No abnormalities were found in either kidneys or hearts in any of the treated groups under microscopic examination. These results suggest that RU 486 successfully prevented the hypertension produced by the long-term administration of dexamethasone in male Sprague-Dawley rats.

10755 Background: To evaluate the effectiveness and tolerability of long -term treatment with capecitabine in metastatic breast cancer patients. Capecitabine (C) has been administered offering clinical benefit to women with metastatic breast cancer (MBC) (ORR: 42%). The aim of this trial was to evaluate the efficacy and tolerance of capecitbine in long-term treatment, administered as first, second and third line treatment in MBC. Methods: Patients ≥ 18 years old with MBC, ECOG performance status (PS) ≤2, HER-2 neu negative, non-chemotherapy naive were included in this prospective, multicentre, non-randomized. To date, twenty-two ambulatory patients were evaluable for toxicity and response. Median age 59.2 years (37–81). All of patients had previously received adjuvant treatment. Hormonal therapy were allowed as clinically required. They received three weekly cycles of oral capecitabine 1000–1250 mg/m2 twice daily, days 1–14, followed one week rest until progression or relapse. Results: The overall response rate (ORR) is including PR, CR, and EE 78%. The median treatment duration was 14 months, median range (3–32). Median progression-free and overall survival have not yet been reached. The most common grade ½ (NCIC CTC) treatment related adverse events were /23, hand foot syndrome 4/23, diarrea 1/23. Conclusions: These preliminary data confirm that the treatment with capecitabine (C) is an effective and well tolerated regiment in metastatic breast cancer patients. No significant financial relationships to disclose.

The open surgical venous cut-down technique is widely performed in cases of long-term treatment including administration of chemotherapy, parenteral nutrition, or replacement therapies. However, it has been recommended to avoid this technique considering the resultant unpredictable alterations in the veins draining the relevant site, especially in patients who may need central venous cannulation (CVC) during disease progression. We aimed to report on CVC in a 5-year-old child who had previously undergone bilateral internal jugular venous access by the open venous cut-down technique, in order to highlight the importance of performing the Rapid Central Vein Assessment protocol prior to any intervention and considering to abandon the use of the open surgical venous cut-down technique by gaining experience with ultrasound-guided percutaneous techniques.

1. Captopril or SQ 14 225, administered orally twice a day, reduced the blood pressure of hypertensive patients whatever their clinical diagnosis and even when their plasma renin activity was ‘normal’ or low. 2. Long-term administration of captopril, either alone or together with diuretics, provides a powerful new tool with which to treat ambulatory hypertensive patients. 3. The renin system may play an important role in maintaining blood pressure in a majority of hypertensive patients.
