Trastuzumab in Esophagogastric Cancer: HER2-Testing and Treatment Reality outside Clinical Studies in Germany.

We analysed trends over time in palliative first-line chemotherapy in patients with locally advanced or metastatic esophagogastric cancer. Special focus was on frequency and quality of HER2-testing and trends in drug use in combination with trastuzumab. Earlier published data about patients treated outside clinical studies showed a relatively low rate of HER2-testing and insufficient test quality. A total of 2,808 patients retrospectively documented in Therapiemonitor (®) from 2006 to 2013 were analysed regarding treatment intensity and trends in used drugs. Data on HER2-testing and therapies were analysed in two cohorts documented in 2010 and 2011 (1) compared to 2012 and 2013 (2). Treatment intensity increased: 49.3% of patients received at least a triplet in 2013 compared to 10.1% in 2006. In cohort 2 HER2 expression was tested in 79.1% of the cases. Still, in 26.9% testing was not done as requested by guidelines. Good performance status, multiple metastases, age ≤ 65 years, the objective "to prevent progression," good cognitive capabilities, estimated good compliance, and social integration positively influenced the probability of HER2-testing; comorbidities negatively affected it. Usage of the combination of fluoropyrimidines and cisplatin with trastuzumab declined from 67% in cohort 1 to 50% in cohort 2.

Diagnostic performance of an Aspergillus-specific nested PCR assay in cerebrospinal fluid samples of immunocompromised patients for detection of central nervous system aspergillosis.

Central nervous system (CNS) invasive aspergillosis (IA) is a fatal complication in immunocompromised patients. Confirming the diagnosis is rarely accomplished as invasive procedures are impaired by neutropenia and low platelet count. Cerebrospinal fluid (CSF) cultures or galactomannan (GM) regularly yield negative results thus suggesting the need for improving diagnostic procedures. Therefore the performance of an established Aspergillus-specific nested polymerase chain reaction assay (PCR) in CSF samples of immunocompromised patients with suspicion of CNS IA was evaluated. We identified 113 CSF samples from 55 immunocompromised patients for whom CNS aspergillosis was suspected. Of these patients 8/55 were identified as having proven/probable CNS IA while the remaining 47 patients were classified as having either possible (n = 22) or no CNS IA (n = 25). PCR positivity in CSF was observed for 8/8 proven/probable, in 4/22 possible CNS IA patients and in 2/25 NoIA patients yielding sensitivity and specificity values of 1.0 (95% CI 0.68-1) and 0.93 (95% CI 0.77-0.98) and a positive likelihood ratio of 14 and negative likelihood ratio of 0.0, respectively, thus resulting in a diagnostic odds ratio of ∞. The retrospective analysis of CSF samples from patients with suspected CNS IA yielded a high sensitivity of the nested PCR assay. PCR testing of CSF samples is recommended for patients for whom CNS IA is suspected, especially for those whose clinical condition does not allow invasive procedures as a positive PCR result makes the presence of CNS IA in that patient population highly likely.

Cetuximab in combination with capecitabine, irinotecan, and radiotherapy for patients with locally advanced rectal cancer: results of a Phase II MARGIT trial.

PURPOSE: To evaluate the safety and efficacy of preoperative radiotherapy (RT) in combination with cetuximab, capecitabine, and irinotecan in patients with locally advanced rectal cancer. METHODS AND MATERIALS: Patients with rectal cancer (clinical stage T3/4 or N+) were scheduled to receive cetuximab (400 mg/m(2) Day 1, 250 mg/m(2) Days 8, 15, 22, 29) in combination with weekly irinotecan 40 mg/m(2) and capecitabine 500 mg/m(2) twice daily (Days 1-38). RT was given to a dose of 50.4 Gy (45 + 5.4 Gy). Primary endpoint was toxicity, and antitumor activity as assessed by the pathologic complete remission (pCR) rate was a secondary endpoint. RESULTS: Fifty patients were enrolled; 88% showed T3 or T4 and 76% nodal-positive tumors with a median distance from the anal verge of 7.5 cm. The actual dose intensity was as follows (median/mean, %): cetuximab 100/92, irinotecan 100/91, capecitabine 100/89). Main adverse events Grades 2/3/4 were (National Cancer Institute common toxicity criteria version 3.0, %): leukocytopenia 6/2/2, nausea/vomiting 4/2/0, diarrhea 34/30/0, proctitis 26/2/0, elevation of liver transaminases 8/10/0, and acnelike skin rash 46/6/0. All patients underwent surgery, and no postoperative deaths occurred. Eighty-four percent underwent low-anterior resection, and 68% of the specimen exhibited moderate or good tumor regression, but only 4 patients had a pCR. CONCLUSION: Preoperative chemoradiation with cetuximab-CapIri-RT has manageable toxicity, with diarrhea being the most commonly observed adverse event. Nevertheless, the efficacy of this regimen with a pCR rate of only 8% was significantly lower than that observed in a previous Phase I trial.

Leukocytoclastic vasculitis and acute renal failure after influenza vaccination in an elderly patient with myelodysplastic syndrome.

BACKGROUND: Influenza vaccination is recommended for individuals over 65 years of age and for all patients with chronic diseases who are at risk. Side effects which are seen in 1-10% of the vaccinated individuals are usually mild and consist of local reactions and constitutional symptoms. Since 1974, about 30 cases of vasculitis following influenza vaccination have been reported. CASE REPORT: We here describe a 70-year-old male patient with a 5-year history of myelodysplastic syndrome, who had received continuous steroid treatment since 2004 and presented with leukocytoclastic vasculitis and acute renal failure requiring hemodialysis therapy 1 week after influenza vaccination. High-dose steroid treatment was promptly initiated, but hemodialysis was needed for 9 days. Maintained steroid treatment for 2 weeks was associated with complete recovery of renal function and skin lesions. CONCLUSION: As influenza vaccination is increasingly used, physicians should be aware of the potential serious side effect of leukocytoclastic vasculitis, particularly in patients who are immunocompromised either due to an underlying disorder or as a treatment-related side effect.
