Communicative reprogramming non-curative hepatocellular carcinoma with low-dose metronomic chemotherapy, COX-2 inhibitor and PPAR-gamma agonist: a phase II trial.

Systemic therapy for advanced hepatocellular carcinoma (HCC) is still challenging. A biomodulatory therapy approach targeting the communicative infrastructure of HCC, including metronomic low-dose chemotherapy with capecitabine, pioglitazone and rofecoxib, has been evaluated in patients with non-curative HCC. Altogether 38 patients were evaluable in this one-arm, multicenter phase II trial. The primary endpoint, median progression-free survival was 2.7 months (95% CI: 1.6-3.79) for all evaluable patients and 8.4 months (95% CI: 0-18.13) for patients ≥ 6 weeks on protocol. Median overall survival (OS) was 6.7 months (95% CI: 4.08-9.31) and 9.4 months (95% CI: 4.82-13.97), respectively. Most common adverse events were edemas grade 3, which were commonly related to the advanced stage, with 66% of the patients suffering from liver cirrhosis. Exploratory data analyses showed significant impact of ECOG performance status grade 0 versus 1 and CLIP score 0/1 versus > 1 on OS, 9.8 months (95% CI: 4.24-15.35) versus 2.7 months (95% CI: 1.03-4.36; P = 0.002), and 9.8 months (95% CI: 3.23-16.37) versus 4.4 months (95% CI: 3.14-5.66; P = 0.009), respectively. Preceding tumor surgery had significant beneficial impact on survival, as well as maximal tumor diameter of < 5 cm. The correlation of C-reactive protein decrease with significantly improved OS underlines the close link between inflammation and tumor control. Biomodulatory therapy in advanced HCC may be a low toxic, efficacious treatment and principally demonstrates that such approaches should be followed further for treatment of advanced HCC.

Biomodulatory Treatment of Patients with Castration-Resistant Prostate Cancer: A Phase II Study of Imatinib with Pioglitazone, Etoricoxib, Dexamethasone and Low-Dose Treosulfan.

Therapeutic options for patients with castration-resistant prostate cancer (CRPC) remain limited. In a multicenter, Phase II study, 65 patients with histologically confirmed CRPC received a biomodulatory regimen during the six-month core study. Treatment comprised daily doses of imatinib mesylate, pioglitazone, etoricoxib, treosulfan and dexamethasone. The primary endpoint was prostate-specific antigen (PSA) response. Responders could enter an extension phase until disease progression or intolerable toxicity occurred. Mean PSA was 45.3 ng/mL at baseline, and 77 % of patients had a PSA doubling time <3 months. Of the 61 evaluable patients, 37 patients (60.6 %) responded or had stable disease and 23 of them (37.7 % of 61 patients) were PSA responders. Among the 23 responders mean PSA decreased from 278.9 ± 784.1 ng/mL at baseline to 8.8 ± 11.6 ng/mL at the final visit (week 24). The progression-free survival (PFS) was 467 days in the ITT population. Of the 947 adverse events, 57.6 % were suspected to be drug-related, 13.8 % led to dose adjustment or permanent discontinuation and 40.2 % required concomitant medication. This novel combination approach led to an impressive PSA response rate of 37.7 % in CRPC patients. The good PSA response and PFS rate combined with the manageable toxicity profile suggest an alternative treatment option.

Extracorporeal photopheresis in 62 patients with acute and chronic GVHD: results of treatment with the COBE Spectra System.

In this retrospective analysis, 30 patients with acute GVHD (aGVHD) and 32 patients with chronic GVHD (cGVHD) treated with extracorporeal photopheresis (ECP) performed by the COBE Spectra System were evaluated. After 3 months of ECP treatment, a CR and PR were observed in 9 (30%) and 6 (20%) patients with aGVHD and in 2 (6%) and 12 (38%) patients with cGVHD. In 16 (53%) patients with aGVHD and 9 (28%) with cGVHD ECP treatment was already stopped after 3 months. One (3%) patient with aGVHD and 7 (22%) patients with cGVHD received new additional immunosuppressive therapy started during the first 3 months of ECP treatment and were classified as 'nonresponder' with regard to ECP. Of these patients a PR was achieved in one patient with aGVHD and in three patients with cGVHD. Steroids could be tapered by 50 in 83% of patients with aGVHD and in 29% of patients with cGVHD after 3 months of ECP treatment. Patients with aGVHD achieving a CR or PR showed a significant improved OS after allo-SCT (P=0.019). ECP is associated with significant response rates and successful reduction of steroids in patients with GVHD.

[Unusual skin alterations in a 72-year-old patient with multiple myeloma]. / Ungewöhnliche Hautveränderungen bei 72-jähriger Patientin mit multiplem Myelom.

We report on a 72-year-old female patient with multiple myeloma who presented with alopecia and eye-catching alterations of the skin and the nails. A biopsy of the skin could confirm the diagnosis of immunoglobulin light chain (AL) amyloidosis, which was also suspected of having affected other organs. After six cycles of a cytoreductive therapy with bortezomib and dexamethasone a very good partial response of the multiple myeloma was seen and an improvement in the skin and nail alterations could be achieved.

Pioglitazone, etoricoxib, interferon-α, and metronomic capecitabine for metastatic renal cell carcinoma: final results of a prospective phase II trial.

We enrolled 45 patients with metastatic renal cell carcinoma (RCC) at a progressive disease between March 2003 and April 2008 to assess the impact of an anti-inflammatory treatment regime in combination with metronomic low-dose chemotherapy. 42% of the patients had been systemically pre-treated. Therapy consisted of etoricoxib 60 mg daily plus pioglitazone 60 mg daily, day 1+, low-dose interferon-α 4.5 MU sc three times a week, week 1+ and low-dose capecitabine 1 g/m(2) twice daily orally for 14 days, every 3 weeks, day 1+, until disease progression. Objective response was observed in 35% of the patients (PR 27, CR 9%), which was paralleled by strong CRP decline for all patients with initially elevated CRP levels (n = 32). CRP values decreased from mean 42.3 mg/L (range 9.1-236), to 11.1 mg/L, (range 1.1-35.6), P = 0.006. Median overall survival and progression-free survival for the total cohort were 26.9 and 7.2 months for patients with elevated CRP 24.4 and 11.3 months (95% CI, 22.8-31.0/5.7-16.9) and 13.8-2.6 months (95% CI, 6.5-21.1/0.4-4.8) for the non-elevated CRP group, respectively (P = 0.082/0.017). Median observation time: 26.1 months; Overall survival at 5 years: 18%. Toxicity>WHO grade 3 was reported: Hand-foot syndrome in 16 patients (36%), diarrhea in 4, and pneumonia in 2 patients. Our data allow us to conclude that the control of tumor-associated inflammation is an important therapeutic principle in patients with metastatic RCC.

Vaccination against pandemic H1N1 (2009) in patients after allogeneic hematopoietic stem cell transplantation: a retrospective analysis.

PURPOSE: Limited data are available on immunologic responses to primary pandemic H1N1 (2009) vaccination in recipients of allogeneic hematopoietic stem cell transplantation (HSCT) recipients. In 2009 serologic responses to either pandemic H1N1 (2009) vaccine (n = 36) or pandemic H1N1 (2009) infection (n = 2) were studied in 38 HSCT recipients. METHODS: Responses were measured with a standard hemagglutination-inhibition assay. Fourteen patients had active chronic graft-versus-host disease (cGvHD) at the time of vaccination/infection and seven patients had cGvHD in remission; 11 patients had no immunosuppressive therapy, and 27 patients were on immunosuppressive therapy. Nineteen patients (53%) responded to pandemic H1N1 (2009) vaccination. Two patients had pandemic H1N1 (2009) infection without prior vaccination, and one patient had severe pandemic H1N1 (2009) infection with acute respiratory distress syndrome despite prior single vaccination. RESULTS: Non-responders to pandemic H1N1 (2009) vaccination more often had cGvHD (65 vs. 53%) and received second- or third-line therapy (53 vs. 11%), while responders mostly had first-line therapy for cGvHD. While vaccine responders had no or single agent immunosuppressive therapy, non-responders frequently received moderate or intense immunosuppressive therapy. All vaccine recipients previously treated with rituximab were non-responders. CONCLUSIONS: In summary, the overall response to pandemic H1N1 (2009) vaccination in HSCT recipients was modest. Patients receiving combined immunosuppressive therapy for steroid-refractory cGvHD barely responded to pandemic H1N1 (2009) vaccination.

[Preventive crisis management in general outpatient palliative care - prospectively cross-sectional study of General Practitioners in Eastern Bavaria]. / Vorbeugendes Krisenmanagement in der allgemeinen ambulanten Palliativversorgung. Prospektive Querschnittstudie bei Hausärzten in Ostbayern.

BACKGROUND: General out-patient palliative care (GOPC) must be integrated into the care of patients with life-limiting diseases. Aim of the study was to evaluate experiences of general practitioners concerning advance directives and palliative emergency sheets. METHODS: A self-provided survey was mailed to all general practitioners in Regensburg (cross-sectional study). Main outcome measures included responses regarding a palliative emergency sheet (PES) and a palliative emergency plan (PEP). The investigation period was four months. The analysis was performed using defined criteria (e. g. professional experience concerning palliative care patients, patients treated in nursing homes, patients with dementia). RESULTS: Sixty-nine questionnaires from 259 were analysed (response rate 27 %). 86 % of respondents named practical experience in the care of palliative patients, 46 % named theoretical knowledge in this field. 41 % and 40 % consider creating an advance directive for their practical work as important/very important (p = 0.004 concerning the treatment of more than five palliative care patients per three months). 52 % and 49 % regard a PES or a PEP to be relevant (PES median: 6.5, SD ± 2.7; PEP median: 6.5 SD ± 2.9; inter-group analysis p < 0.05). 94 % of respondents name the general practitioner to be suitable for creating an advance directive. CONCLUSION: In Germany, GOPC in end-of-life care is very important. This study shows that advance directives were declared as an important instrument for patients? autonomy. The sense of PES and PEP to ensure patients? autonomy, especially for acute emergency medical palliative care, must be better recognized. However, the increase in acceptance in the GOPC for such instruments must be disclosed. Further studies to investigate this problem are necessary.

Isolated cerebral manifestation of Epstein-Barr virus-associated post-transplant lymphoproliferative disorder after allogeneic hematopoietic stem cell transplantation: a case of clinical and diagnostic challenges.

We present the case of a 49-year-old male patient with Epstein-Barr virus (EBV)-associated post-transplant lymphoproliferative disorder (PTLD) limited to the brain that occurred 6 months after allogeneic hematopoietic stem cell transplantation (HSCT). Clinical symptoms included mental confusion, ataxia, and diplopia. Magnetic resonance imaging (MRI) revealed cerebellar and periventricular lesions consistent with an inflammatory process. Cerebrospinal fluid (CSF) analysis, but not peripheral blood, was positive for EBV-DNA, but no malignant cells were found. Brain biopsy was not feasible because of low platelet counts. As we considered a diagnosis of either EBV-associated encephalitis or PTLD, the patient was treated with rituximab combined with antiviral therapy. However, the cerebral lesions progressed and follow-up CSF testing revealed immunoglobulin H clonality as evidence of a malignant process. Subsequent treatment attempts included 2 donor lymphocyte infusions (DLI). Despite treatment, the patient died from autopsy-proven PTLD within 8 weeks of the onset of symptoms. This case demonstrates the clinical and diagnostic challenges of primary cerebral PTLD in a patient following allogeneic HSCT.
