Posaconazole salvage treatment in paediatric patients: a multicentre survey

While a paediatric dosage has not been defined, posaconazole is occasionally being used in children. We conducted a multicentre retrospective survey and identified 15 patients (median age 10 years [range 3.6-17.5]) who received posaconazole salvage therapy for proven (9 patients) or probable (6 patients) invasive fungal infections. Posaconazole was administered for a median of 32 days (range 4-262) at a median dosage of 21 mg/kg (range 4.8-33.3). None of the patients discontinued therapy due to adverse events, which were mostly mild and observed in 11 patients. Complete or partial responses were observed in 4/7 patients with zygomycosis, 3/4 patients with invasive mould infection, 1/2 patients with invasive aspergillosis and 1/2 patients with chronic disseminated candidiasis. We conclude from the data that posaconazole displays favourable safety and tolerance and may be useful for management of individual paediatric patients with invasive infections.

Surgical hip dislocation for osteochondral transplantation as a salvage procedure for a femoral head impaction fracture

Obturator anterior hip dislocation is very rare. Poor results are described in patients with additional large transchondral fractures and treatment of these injuries remains challenging. Appropriate treatment recommendations are missing in the literature. This case report introduces surgical hip dislocation for osteochondral autograft transplantation with graft harvest from the nonweightbearing area of the head-neck junction as a salvage procedure in a large femoral head defect. We report the treatment and outcome of a 48-year-old man who sustained an anterior dislocation of the left hip after a motorcycle accident. After initial closed reduction in the emergency room, imaging analysis revealed a large osteochondral defect of the femoral head within the weightbearing area (10 × 20 mm, depth: 5 mm). The hip was exposed with a surgical hip dislocation using a trochanteric osteotomy. An osteochondral autograft was harvested from a nonweightbearing area of the femoral head and transferred into the defect. The patient was prospectively examined clinically and radiologically. Two years postoperatively, the patient was free of pain and complaints. The function of the injured hip was comparable to that of the contralateral, healthy hip and showed satisfying radiologic results. Surgical hip dislocation with a trochanteric flip osteotomy is a simple, one-step technique that allows full inspection of the hip to treat osteochondral femoral defects by osteochondral transplantation. The presented technique, used as a salvage procedure in a large femoral head defect, yielded good clinical and satisfying radiologic outcomes at the midterm.

Preliminary Experience in Treatment of Papillary and Macular Retinoblastoma: Evaluation of Local Control and Local Complications After Treatment with Linear Accelerator-Based Stereotactic Radiotherapy with Micromultileaf Collimator as Second-Line or Salvage Treatment after chemotherapy

To determine the local control and complication rates for children with papillary and/or macular retinoblastoma progressing after chemotherapy and undergoing stereotactic radiotherapy (SRT) with a micromultileaf collimator.

Clinical outcomes after PCI for acute coronary syndrome in unprotected left main coronary artery disease: insights from the Swiss Acute Left Main Coronary Vessel Percutaneous Management (SALVage) study

Unprotected left main (ULM) coronary artery disease is encountered in 3%-10% of coronary angiograms and is associated with high mortality. The survival of patients with ULM disease presenting with acute coronary syndromes (ACS) depends on different variables and is lowest in those with cardiogenic shock (CS). The aim of the present study was to estimate the impact of baseline characteristics on the subsequent clinical outcome in patients treated by percutaneous coronary intervention (PCI) of ULM for ACS.

Viral suppression rates in salvage treatment with raltegravir improved with the administration of genotypic partially active or inactive nucleoside/tide reverse transcriptase inhibitors

Nucleoside reverse transcriptase inhibitors (NRTIs) are often administered in salvage therapy even if genotypic resistance tests (GRTs) indicate high-level resistance, but little is known about the benefit of these additional NRTIs.

Treatment of advanced soft-tissue sarcomas using a combined strategy of high-dose ifosfamide, high-dose doxorubicin and salvage therapies

Having determined in a phase I study the maximum tolerated dose of high-dose ifosfamide combined with high-dose doxorubicin, we now report the long-term results of a phase II trial in advanced soft-tissue sarcomas. Forty-six patients with locally advanced or metastatic soft-tissue sarcomas were included, with age <60 years and all except one in good performance status (0 or 1). The chemotherapy treatment consisted of ifosfamide 10 g m(-2) (continuous infusion for 5 days), doxorubicin 30 mg m(-2) day(-1) x 3 (total dose 90 mg m(-2)), mesna and granulocyte-colony stimulating factor. Cycles were repeated every 21 days. A median of 4 (1-6) cycles per patient was administered. Twenty-two patients responded to therapy, including three complete responders and 19 partial responders for an overall response rate of 48% (95% CI: 33-63%). The response rate was not different between localised and metastatic diseases or between histological types, but was higher in grade 3 tumours. Median overall survival was 19 months. Salvage therapies (surgery and/or radiotherapy) were performed in 43% of patients and found to be the most significant predictor for favourable survival (exploratory multivariate analysis). Haematological toxicity was severe, including grade > or =3 neutropenia in 59%, thrombopenia in 39% and anaemia in 27% of cycles. Three patients experienced grade 3 neurotoxicity and one patient died of septic shock. This high-dose regimen is toxic but nonetheless feasible in multicentre settings in non elderly patients with good performance status. A high response rate was obtained. Prolonged survival was mainly a function of salvage therapies.

Oral SCH 39304 as primary, salvage, and maintenance therapy for cryptococcal meningitis in AIDS

To determine the efficacy and toxicity of SCH 39304 in the treatment and suppression of cryptococcal meningitis, we conducted a prospective, noncomparative study in three groups of patients: patients with acute cryptococcal meningitis, patients with acute cryptococcal meningitis in whom other therapies have failed (salvage), and patients who required maintenance therapy. As primary therapy, the patients received up to 14 days or 1 g of amphotericin B followed by SCH 39304 200 mg once daily for 12 weeks. As maintenance therapy, the patients received SCH 39304 600 mg once weekly for 12 months. Of five salvage patients, none completed the study. Two patients died, two patients clinically deteriorated, and one patient was noncompliant. Two of three patients with acute cryptococcal meningitis completed the 12-week primary therapy, and one patient was discontinued from therapy because of a skin rash (95% confidence interval, 14-100%). All four patients who were receiving weekly maintenance therapy followed up to 27 weeks were clinically stable with no change in their serum cryptococcal antigen titer from baseline when the study was prematurely terminated. Elevation of liver function test results developed in three patients and skin rash developed in one patient. The unique pharmacologic and pharmacokinetic properties of SCH 39304 (low incidence of toxicity, long serum half-life, and good penetration into the cerebrospinal fluid) lend promise to pursue other triazole antifungals at higher doses as primary therapy and less frequent dosing for maintenance therapy.

[11C]Choline PET/CT for targeted salvage lymph node dissection in patients with biochemical recurrence after primary curative therapy for prostate cancer. Preliminary results of a prospective study

INTRODUCTION: In this prospective study we set out to investigate the diagnostic value of [(11)C]choline-PET/CT in patients with suspected lymph node metastases before salvage lymph node dissection. PATIENTS AND METHODS: 15 consecutive patients with rising PSA underwent [(11)C]choline-PET/CT and consecutive open salvage pelvic/retroperitoneal extended lymph node dissection due to uptake of [(11)C]choline in at least 1 lymph node. Mean age was 62.1 (range 53-73). RESULTS: [(11)C]choline-PET/CT results were compared with the histopathology reports and clinical follow-up (mean 13.7 months, range 6-24). Mean time to progression was 23.6 months (range 4-81). [(11)C]choline uptake was observed in nodes along the external and internal and common iliac arteries and in the paraaortic region. A positive histology was reported in 8/15 patients. Only one patient had a PSA nadir of <0.1 ng/ml after salvage surgery. Another patient had stable disease with a PSA of 0.5 ng/ml. Three patients developed bone metastases during follow-up. CONCLUSIONS: This interim analysis indicates that [(11)C]choline-PET/CT may be a useful technique in detection of lymph node metastases when rising PSA occurs after definite prostate cancer therapy. The presented cohort is limited in size, but there is still strong evidence that the patients benefit from [(11)C]choline-PET/CT and consecutive salvage lymph node dissection is rather small.

Myocardial salvage through coronary collateral growth by granulocyte colony-stimulating factor in chronic coronary artery disease: a controlled randomized trial

BACKGROUND: The efficacy of granulocyte colony-stimulating factor (G-CSF) for coronary collateral growth promotion and thus impending myocardial salvage has not been studied so far, to our best knowledge. METHODS AND RESULTS: In 52 patients with chronic stable coronary artery disease, age 62+/-11 years, the effect on a marker of myocardial infarct size (ECG ST segment elevation) and on quantitative collateral function during a 1-minute coronary balloon occlusion was tested in a randomized, placebo-controlled, double-blind fashion. The study protocol before coronary intervention consisted of occlusive surface and intracoronary lead ECG recording as well as collateral flow index (CFI, no unit) measurement in a stenotic and a > or =1 normal coronary artery before and after a 2-week period with subcutaneous G-CSF (10 microg/kg; n=26) or placebo (n=26). The CFI was determined by simultaneous measurement of mean aortic, distal coronary occlusive, and central venous pressure. The ECG ST segment elevation >0.1 mV disappeared significantly more often in response to G-CSF (11/53 vessels; 21%) than to placebo (0/55 vessels; P=0.0005), and simultaneously, CFI changed from 0.121+/-0.087 at baseline to 0.166+/-0.086 at follow-up in the G-CSF group, and from 0.152+/-0.082 to 0.131+/-0.071 in the placebo group (P<0.0001 for interaction of treatment and time). The absolute change in CFI from baseline to follow-up amounted to +0.049+/-0.062 in the G-CSF group and to -0.010+/-0.060 in the placebo group (P<0.0001). CONCLUSIONS: Subcutaneous G-CSF is efficacious during a short-term protocol in improving signs of myocardial salvage by coronary collateral growth promotion.

Use of EORTC Target Definition Guidelines for Dose-Intensified Salvage Radiation Therapy for Recurrent Prostate Cancer: Results of the Quality Assurance Program of the Randomized Trial SAKK 09/10

PURPOSE Different international target volume delineation guidelines exist and different treatment techniques are available for salvage radiation therapy (RT) for recurrent prostate cancer, but less is known regarding their respective applicability in clinical practice. METHODS AND MATERIALS A randomized phase III trial testing 64 Gy vs 70 Gy salvage RT was accompanied by an intense quality assurance program including a site-specific and study-specific questionnaire and a dummy run (DR). Target volume delineation was performed according to the European Organisation for the Research and Treatment of Cancer guidelines, and a DR-based treatment plan was established for 70 Gy. Major and minor protocol deviations were noted, interobserver agreement of delineated target contours was assessed, and dose-volume histogram (DVH) parameters of different treatment techniques were compared. RESULTS Thirty European centers participated, 43% of which were using 3-dimensional conformal RT (3D-CRT), with the remaining centers using intensity modulated RT (IMRT) or volumetric modulated arc technique (VMAT). The first submitted version of the DR contained major deviations in 21 of 30 (70%) centers, mostly caused by inappropriately defined or lack of prostate bed (PB). All but 5 centers completed the DR successfully with their second submitted version. The interobserver agreement of the PB was moderate and was improved by the DR review, as indicated by an increased κ value (0.59 vs 0.55), mean sensitivity (0.64 vs 0.58), volume of total agreement (3.9 vs 3.3 cm(3)), and decrease in the union volume (79.3 vs 84.2 cm(3)). Rectal and bladder wall DVH parameters of IMRT and VMAT vs 3D-CRT plans were not significantly different. CONCLUSIONS The interobserver agreement of PB delineation was moderate but was improved by the DR. Major deviations could be identified for the majority of centers. The DR has improved the acquaintance of the participating centers with the trial protocol.

Ankle dorsiflexion arthrodesis to salvage Chopart's amputation with anterior skin insufficiency

BACKGROUND In Chopart-level amputations the heel often deviates into equinus and varus when, due to the lack of healthy anterior soft tissue, rebalancing tendon transfers to the talar head are not possible. Consequently, anterior and lateral wound dehiscence and ulceration may occur requiring higher-level amputation to achieve wound closure, with considerable loss of function for the patients. METHODS Twenty-four consecutive patients (15 diabetes, 6 trauma, and 3 tumor) had Chopart's amputation and simultaneous or delayed additional ankle dorsiflexion arthrodesis to allow for tension-free wound closure or soft tissue reconstruction, or to treat secondary recurrent ulcerations. Percutaneous Achilles tendon lengthening and subtalar arthrodesis were added as needed. Wound healing problems, time to fusion and full weight-bearing in the prosthesis, complications in the prosthesis, and the ambulatory status were assessed. Satisfaction and function were evaluated by the AmpuPro score and the validated Prosthesis Evaluation Questionnaire scale. RESULTS Five patients had successful soft tissue healing and fusions but died of their underlying disease 2 to 46 months after the operation. Two diabetic patients required a transtibial amputation. The other 17 patients were followed for 27 months (range, 13-63). The average age of the 4 women and 13 men was 53.9 years (range, 16-87). Postoperative complications included minor wound healing problems in 8 patients, wound breakdown requiring revision in 4, phantom pain in 3, residual equinus in 1, and adjacent scar carcinoma in 1 patient. The time to full weight-bearing in the prosthesis ranged from 6 to 24 weeks (mean 10). The mean AmpuPro score was 107 points (of 120), and the mean Prosthesis Evaluation Questionnaire scale was 147 points (of 200). No complications occurred with the prosthesis. Twelve patients lost 1 to 2 mobility classes (mean 0.9). The arthrodeses all healed within 2.5 months (range, 1.5 to 5 months). CONCLUSION Adding an ankle arthrodesis to a Chopart's amputation either immediately or in a delayed fashion to treat anterior soft tissue complications was a successful salvage in most patients at this amputation level. It enabled the patients to preserve the advantages of a full-length limb with terminal weight-bearing. LEVEL OF EVIDENCE Level IV, retrospective case series.
