[The Development of Quality Standards for the Psychosocial Outpatient Care of Cancer Patients - Results of a Delphi Survey]. / Die Entwicklung von Qualitätsstandards für die ambulante psychosoziale Krebsberatung ­ Ergebnisse einer Delphibefragung.

BACKGROUND: The psychosocial outpatient care of cancer patients and their families is a central element of oncological care. To date, the provision of care to this group is very heterogeneous in terms of the spectrum of services offered and quality of care. The aim of this study was to develop a multidimensional classification of quality standards for psychosocial outpatient cancer counseling. METHOD: We conducted a study using the Delphi method. 97 experts from more than 10 different fields of action or institutional contexts (e. g. mental health care professionals, cancer societies, self-help groups) were included in 3 rounds of Delphi assessment. Finally, 134 single criteria within 9 quality areas (e. g. staff, range of services, documentation) were generated and evaluated for their relevance, clarity, comprehensiveness and level of obligation. RESULT: A total of 119 individual criteria (88.8%) achieved consensus within the 3 Delphi rounds. Hereof, 94 were basic criteria (79%) and 25 optional criteria (21%). The highest number of individual criteria referred to the service spectrum (26 individual criteria), documentation (21) as well as staff and accessibility (16 each). Fifteen criteria (11.2%) achieved no consensus and were removed. CONCLUSION: For the first time, criteria for assessing the quality of psychosocial outpatient cancer counseling with expert consensus are available, facilitating the evaluation of psychosocial outpatient cancer counseling.

[Structural and process quality in outpatient psychosocial cancer counselling centres. evaluating a major funding programme of the "Deutsche Krebshilfe e.V."]. / Struktur- und Prozessqualität in ambulanten psychosozialen Krebsberatungsstellen des Förderschwerpunktes "Psychosoziale Krebsberatung" der Deutschen Krebshilfe.

BACKGROUND: In 2007, the German Cancer Aid ("Deutsche Krebshilfe e.V.") initiated and funded a programme in 28 selected cancer counselling centres in Germany attempting to both promote and strengthen quality assured psychosocial cancer counselling as well as to ensure long-term financing. The accompanying evaluation programme aims to collect structural data of the institutions and to evaluate processes of quality assurance within the sample of cancer counselling centres. METHODS: On the basis of structured research within scientific databases and internet, as well as with the support of experts, characteristics of structural quality of cancer counselling centres were identified. Structural data were collected using a self-developed questionnaire and a semi-structured interview during the on-site visitations of the institutions. RESULTS: The results show homogeneity in some fields of structural quality such as individual psycho-oncological and social counselling, human resources, room facilities, quality assurance, diagnostics, documentation and public relations. Structural quality of the investigated centres appears more heterogeneous with regard to aspects such as availability and accessibility, barrier-free access, group support offers (counselling, sports, arts, etc.) as well as cooperation, financing and written mission statements. CONCLUSION: The investigated cancer counselling centres ensure mainly good minimum standards according to structural quality of cancer counselling. There is potential for further optimisation including cooperation, quality assurance, room facilities and being differentiated in terms of conceptual content and working concepts. Further achievements on quality assured cancer counselling can use the presented data as a basis for describing minimum standards and obligatory quality criteria.

Immunotherapy of patients with hormone-refractory prostate carcinoma pre-treated with interferon-gamma and vaccinated with autologous PSA-peptide loaded dendritic cells--a pilot study.

PURPOSE: We conducted a pilot trial to assess the feasibility and tolerability of a prime/boost vaccine strategy using interferon-gamma (IFN-gamma) and autologous dendritic cells (DCs) pulsed with HLA-A2-specific prostate-specific antigen (PSA) peptides (PSA-1 [141-150]; PSA-2 [146-156]; PSA-3 [154-163]) for the treatment of 12 patients with hormone refractory prostate carcinoma. PATIENTS AND METHODS: All patients were vaccinated four times with intracutaneously injected PSA-peptide loaded DCs after subcutaneous administration of IFN-gamma 2 hr before DC administration (50 microg/m(2) body surface). Objectives were safety, clinical benefit, clinical and biochemical response, quality of life, and immunological parameters. RESULTS: The vaccination was well tolerated without any vaccination-associated adverse events. One partial and one mixed responder were identified, four patients showed stable diseases. Two patients had a decrease and four a slow-down velocity slope in the PSA serum level. All responders showed a positive DTH-response, but only two a slight increase in PSA-peptide specific T-lymphocytes. CONCLUSION: The immunotherapy with IFN-gamma and PSA-peptide loaded DCs was feasible and well tolerated. The observed responses imply a potential antitumor activity.

The efficacy of adjuvant platinum-based chemotherapy in Stage I uterine papillary serous carcinoma (UPSC).

OBJECTIVE: To determine the efficacy of adjuvant platinum-based chemotherapy in Stage I uterine papillary serous carcinoma (UPSC). METHODS: A retrospective multi-institutional investigation was performed to identify surgically staged patients with Stage I UPSC who were (1) treated after surgery with 3-6 courses of platinum-based chemotherapy without radiation from 1990-2003, and (2) followed for a minimum of 12 months, or until recurrence. RESULTS: Six patients (IA-2, IB-3, IC-1) were treated with carboplatin (AUC 6) or cisplatin (50 mg/m2) alone. One patient recurred to the vagina, was treated with chemo-radiation, and is alive and well at 122 months. One patient recurred to the lung, liver, and brain, and died of disease at 24 months. The remaining 4 patients are alive with no evidence of disease 15-124 months (mean 62 months) after treatment. Two patients (IB-1, IC-1) were treated with cisplatin (50 mg/m2) and cyclophosphamide (1000 mg/m2), and both are alive and well with no evidence of disease 75 and 168 months after treatment. Twenty-one patients (IA-5, IB-13, IC-3) were treated with a combination of carboplatin (AUC 6) and paclitaxel (135 mg/m2-175 mg/m2). One patient recurred to the vagina after 3 cycles of carboplatin/paclitaxel, and was treated with chemo-radiation. She is now without evidence of disease 10 months after treatment. At present, all 21 patients with Stage I UPSC treated following surgical staging with carboplatin/paclitaxel chemotherapy are alive and well with no evidence of disease 10-138 months (mean 41 months) after treatment. CONCLUSION: Combination carboplatin/paclitaxel chemotherapy following surgery is effective in the treatment of Stage I UPSC.

Aryl ketones as novel replacements for the C-terminal amide bond of succinyl hydroxamate MMP inhibitors.

A series of succinyl hydroxamate MMP inhibitors were prepared incorporating an aryl amino ketone moiety in place of the more typical C-terminal amino acid amides. Compounds of the C-terminal ketone series displayed potent inhibition of MMPs. Several compounds of the series were shown to be orally bioavailable.

A comparison of inpatient and outpatient school refusers.

This study describes children and adolescents with school refusal who were hospitalized and compares them to a matched group with school refusal who were treated as outpatients in order to examine the use of hospitalization in the treatment of this symptom presentation. The results showed the inpatient group had significantly more depressive disorder, a greater number of diagnoses, more severe symptoms, were more likely to reside in single-parent homes, and were more likely to have been physically abused.

Nasopharyngeal carcinoma in the young: a combined M.D. Anderson and Stanford experience.

From 1956 to 1988, 57 children and young adults (age 4-21 years) with a diagnosis of nasopharyngeal carcinoma were treated at The University of Texas M.D. Anderson Cancer Center (42 patients) and Stanford University Medical Center (15 patients). The male to female ratio was 2:1. Forty-three patients had lymphoepithelioma, seven had undifferentiated neoplasms, and seven had squamous cell carcinoma. Two patients had Stage III disease and the remainder had Stage IV disease at the time of presentation. All patients were treated with primary radiotherapy, and 14 patients also had chemotherapy with combinations of the following drugs: dactinomycin, doxorubicin, bleomycin, cisplatin, cyclophosphamide, fluorouracil, methotrexate, and vincristine. Twenty-six patients are alive 6 to 178 months from the first day of treatment (median 93 months). The 5- and 10-year actuarial survival rates are 51% and 36%, respectively, and the corresponding disease specific survival rates were 51% and 51%. There were no recurrences after 42 months. The patterns of failure were as follows: distant metastasis only, 21 patients; locoregional metastasis only, 1; both, 5. Distant metastases most commonly occurred in bones, lungs, liver, and mediastinal lymph nodes. Chronic treatment-related morbidity was encountered in a significant number of long term survivors. Trends in the data not reaching statistical significance suggest a more favorable prognosis for a) females, b) patients less than or equal to 15 years of age, c) lymphoepithelioma or undifferentiated histologies, d) stages T3-4 NO-1 vs T1-2 N2-3 vs T3-4 N2-3, e) primary tumor dose greater than or equal to 65 Gy and f) patients who received chemotherapy.

Effects of exogenous guanosine on chromatophore differentiation in the axolotl.

Guanosine is shown to dramatically alter the pigment phenotype of axolotls by suppressing melanization and enhancing the biosynthesis and deposition of purine-derived pigments. Phenotypic changes caused by guanosine are manifested by altered chromatophore differentiation patterns such that few black pigment cells (melanophores) differentiate (and those that do are punctate and necrotic in appearance), whereas the development of yellow (xanthophore) and reflecting (iridophore) pigment cells is enhanced. Mechanisms for changes in chromatophore differentiation, and thus pattern formation, are discussed, including the possibility that pigment cells may undergo transdifferentiation in vivo.
