Communication patterns in families affected by parental cancer from the healthy parents' perspective-process evaluation of the complex intervention Family-SCOUT.

PURPOSE: Within families affected by parental cancer, open communication impacts the well-being of parents and their children; however, limited research exists on communication patterns in these families. This sub-study addresses this through the Family-SCOUT study, a multicenter, prospective, interventional, and non-randomized investigation with intervention (IG) and control group (CG). The purpose of this sub-study was to identify and compare the differences in communication patterns between the IG and CG as part of the process evaluation. The research question was addressed in both groups: What communication patterns do healthy parents perceive within their families? METHODS: Using a qualitative approach, the study involved interviewing healthy parents as surrogates for their families. The interviews were audio-recorded, transcribed, and coded using a template analysis. The resulting data were analyzed at the group level. RESULTS: Twenty-three interviews were conducted in the IG and 27 interviews in the CG. The analysis of themes centered on communication patterns as seen in the family structure. Both groups exhibited instances of open communication about fears and wishes as well as the use of child-friendly language when discussing cancer. Notable differences were observed: challenges in open communication with children were sorely reported in CG interviews, and "the illness is discussed when necessary" was sorely described in IG interviews. CONCLUSION: This study underscores the need to address and encourage open communication within families with parental cancer.

A randomized trial on chlorhexidine dressings for the prevention of catheter-related bloodstream infections in neutropenic patients.

BACKGROUND: Central venous catheter (CVC)-related bloodstream infections (CRBSI) are a frequent cause of morbidity and mortality in patients with chemotherapy-induced neutropenia. Chlorhexidine containing catheter securement dressings may prevent CRBSI. PATIENTS AND METHODS: A multicenter randomized, controlled trial was conducted at 10 German hematology departments. We compared chlorhexidine-containing dressings with non-chlorhexidine control dressings in neutropenic patients. The primary end point was the incidence of definite CRBSI within the first 14 days (dCRBSI14) of CVC placement. Secondary end points included combined incidence of definite or probable CRBSI within 14 days (dpCRBSI14), overall (dpCRBSI), incidence of unscheduled dressing changes and adverse events. RESULTS: From February 2012 to September 2014, 613 assessable patients were included in the study. The incidence of dCRBSI14 was 2.6% (8/307) in the chlorhexidine and 3.9% (12/306) in the control group (P = 0.375). Both dpCRBSI14 and dpCRBSI were significantly less frequent in the study group with dpCRBSI14 in 6.5% (20/307) of the chlorhexidine group when compared with 11% (34/306) in the control group (P = 0.047), and dpCRBSI in 10.4% (32/307) versus 17% (52/306), respectively (P = 0.019). The frequency of dressing intolerance with cutaneous and soft tissue abnormalities at the contact area was similar in both groups (12.4% and 11.8%; P = 0.901). CONCLUSIONS: Although the trial failed its primary end point, the application of chlorhexidine containing catheter securement dressings reduces the incidence of definite or probable CRBSI in neutropenic patients.

CNS infections in patients with hematological disorders (including allogeneic stem-cell transplantation)-Guidelines of the Infectious Diseases Working Party (AGIHO) of the German Society of Hematology and Medical Oncology (DGHO).

Infections of the central nervous system (CNS) are infrequently diagnosed in immunocompetent patients, but they do occur in a significant proportion of patients with hematological disorders. In particular, patients undergoing allogeneic hematopoietic stem-cell transplantation carry a high risk for CNS infections of up to 15%. Fungi and Toxoplasma gondii are the predominant causative agents. The diagnosis of CNS infections is based on neuroimaging, cerebrospinal fluid examination and biopsy of suspicious lesions in selected patients. However, identification of CNS infections in immunocompromised patients could represent a major challenge since metabolic disturbances, side-effects of antineoplastic or immunosuppressive drugs and CNS involvement of the underlying hematological disorder may mimic symptoms of a CNS infection. The prognosis of CNS infections is generally poor in these patients, albeit the introduction of novel substances (e.g. voriconazole) has improved the outcome in distinct patient subgroups. This guideline has been developed by the Infectious Diseases Working Party (AGIHO) of the German Society of Hematology and Medical Oncology (DGHO) with the contribution of a panel of 14 experts certified in internal medicine, hematology/oncology, infectious diseases, intensive care, neurology and neuroradiology. Grades of recommendation and levels of evidence were categorized by using novel criteria, as recently published by the European Society of Clinical Microbiology and Infectious Diseases.

Effectiveness of a comprehensive support program for families with parental cancer (Family-SCOUT): results of a multicenter non-randomized controlled trial.

BACKGROUND: Cancer patients with minor children but also their families suffer from significant psychological distress and comorbidity. Protective factors predicting successful coping are well known. Corresponding systematic interventions are rare and limited by access barriers. We developed a comprehensive family-centered intervention for cancer patients with at least one dependent minor. PATIENTS AND METHODS: Family-SCOUT represents a multicentric, prospective, interventional, and controlled study for families with parental cancer and their minor children. In the intervention group (IG), all family members were addressed using a care and case management approach for nine months. Families in the control group (CG) received standard of care. Participating parents were asked to complete the Hospital-Anxiety-Depression-Scale (HADS) questionnaire at enrolment (T0) and after 9 months (T2). The primary outcome was a clinically relevant reduction of distress in at least one parent per family, measured as minimal important difference (MID) of ≥1.6 in the HADS total score. The percentage of families achieving MID is compared between the IG and CG by exact Fisher's test, followed by multivariate confounder analyses. RESULTS: T0-questionnaire of at least one parent was available for 424 of 472 participating families, T2-questionnaire after 9 months was available for 331 families (IG n = 175, CG n = 156). At baseline, both parents showed high levels of distress (HADS total: sick parents IG: 18.7 ± 8.1; CG: 16.0 ± 7.2; healthy partners: IG: 19.1 ± 7.9; CG: 15.2 ± 7.7). The intervention was associated with a significant reduction in parental distress in the IG (MID 70.4% in at least one parent) compared with the CG (MID 55.8%; P = 0.008). Adjustment for group differences from specific confounders retained significance (P = 0.047). Bias from other confounders cannot be excluded. CONCLUSIONS: Parental cancer leads to a high psychosocial burden in affected families. Significant distress reduction can be achieved through an optimized and structured care approach directed at the family level such as family-SCOUT.

A multicentric, randomized, comparative clinical trial to evaluate the efficacy and safety of S-etodolac in the treatment of osteoarthritis in Indian patients.

OBJECTIVE: To compare the efficacy and safety of S-etodolac with etodolac in the treatment of osteoarthritis in Indian patients. MATERIALS AND METHODS: This was a double-blind, multicentric, comparative clinical trial conducted in 108 Indian patients with osteoarthritis. All patients received either S-etodolac ER 300 mg or etodolac ER 600 mg tablets once daily. Assessment was done on the basis of WOMAC score and VAS pain score, patient's and physician's global assessment of the arthritic condition. All patients were evaluated after every 2 weeks for 4 weeks for efficacy and safety variables. RESULTS AND DISCUSSION: Total 49 patients in the test group and 52 patients in the reference group completed the study. There was significant improvement (p < 0.0001) in all WOMAC subscales (pain, stiffness and physical function), WOMAC total score and VAS pain score in both the groups. Patient's and physician's global assessment of the arthritic condition also improved significantly (p < 0.0001). All patients showed improvement in WOMAC and VAS pain score by (3) 20%. There was no significant difference between the groups for the efficacy parameters. The adverse events reported were few and no serious adverse events were reported. Total 5 patients in S-etodolac group and 2 patients in etodolac group dropped out of the study. Only 1 patient dropped out because of the side effects of burning sensation, palpitations and anxiety in the test group. CONCLUSION: The present study has established the efficacy, tolerability and safety of S-etodolac extended release tablets in the treatment of osteoarthritis in Indian patients.

Impact of single-room contact precautions on hospital-acquisition and transmission of multidrug-resistant Escherichia coli: a prospective multicentre cohort study in haematological and oncological wards.

OBJECTIVES: Colonization and infection with third-generation cephalosporin-resistant Escherichia coli (3GCR-EC) are frequent in haematological and oncological patients. In this high-risk setting, German guidelines recommend single-room contact precautions (SCP) for patients with 3GCR-EC that are non-susceptible to fluoroquinolones (F3GCR-EC). However, this recommendation is controversial, as evidence is limited. METHODS: We performed a prospective, multicentre cohort study at four haematology and oncology departments assessing the impact of SCP on hospital-acquired colonization or bloodstream infection (BSI) with F3GCR-EC. Two sites performed SCP for F3GCR-EC patients including single rooms, gloves and gowns (SCP sites), and two did not (NCP sites). Active screening for 3GCR-EC was performed and isolates were characterized with molecular typing methods including whole genome sequencing and core genome multiple locus sequence typing to assess patient-to-patient transmission. Potential confounders were assessed by competing-risk regression analysis. RESULTS: Within 12 months, 1386 patients at NCP sites and 1582 patients at SCP sites were included. Hospital-acquisition of F3GCR-EC was observed in 22/1386 (1.59%) and 16/1582 (1.01%) patients, respectively (p 0.191). There were 3/1386 (0.22%) patients with BSI caused by F3GCR-EC at NCP sites and 4/1582 (0.25%) at SCP sites (p 1.000). Patient-to-patient transmission occurred in three cases at NCP and SCP sites each (p 1.000). The number of patients needed to screen in order to prevent one patient-to-patient transmission of F3GCR-EC was determined to be 3729. CONCLUSIONS: Use of SCP had no significant impact on hospital-acquisition or patient-to-patient transmission of F3GCR-EC in this high-risk setting.

High-dose methotrexate-based immuno-chemotherapy for elderly primary CNS lymphoma patients (PRIMAIN study).

To investigate immuno-chemotherapy for elderly immuno-competent patients (⩾65 years) with newly diagnosed primary central nervous system lymphoma, we conducted a multicentre single-arm trial. One cycle consisted of rituximab (375 mg/m2, days 1, 15, 29), high-dose methotrexate (3 g/m2 days 2, 16, 30), procarbazine (60 mg/m2 days 2-11) and lomustine (110 mg/m2, day 2)-R-MPL protocol. Owing to infectious complications, we omitted lomustine during the study and consecutive patients were treated with the R-MP protocol. Three cycles were scheduled and repeated on day 43. Subsequently, patients commenced 4 weekly maintenance treatment with procarbazine (100 mg for 5 days). Primary end point was complete remission (CR) after 3 cycles. We included 107 patients (69 treated with R-MPL and 38 with R-MP). In all, 38/107 patients achieved CR (35.5%) and 15 (14.0%) achieved partial remission. R-MP was associated with a lower CR rate (31.6%) compared with R-MPL (37.7%), but respective 2-year progression-free survival (All 37.3%; R-MP 34.9%; R-MPL 38.8%) and overall survival (All 47.0%; R-MP 47.7%; R-MPL 46.0%) rates were similar. R-MP was associated with less ⩾grade 3 toxicities compared with R-MPL (71.1% vs 87.0%). R-MP is more feasible while still associated with similar efficacy compared with R-MPL and warrants further improvement in future studies.

Reduced-toxicity conditioning with treosulfan, fludarabine and ATG as preparative regimen for allogeneic stem cell transplantation (alloSCT) in elderly patients with secondary acute myeloid leukemia (sAML) or myelodysplastic syndrome (MDS).

We investigated a dose-reduced conditioning regimen consisting of treosulfan and fludarabine followed by allogeneic stem cell transplantation (SCT) in 26 patients with secondary AML or MDS. Twenty patients were transplanted from matched or mismatched unrelated donors and six from HLA-identical sibling donors. The median age of the patients was 60 years (range, 44-70). None of the patients was eligible for a standard myeloablative preparative regimen. No graft-failure was observed, and leukocyte and platelet engraftment were observed after a median of 16 and 17 days, respectively. Acute graft-versus-host disease (GvHD) grade II-IV was seen in 23% and severe grade III GvHD in 12% of the patients. No patients experienced grade IV acute GvHD. Chronic GvHD was noted in 36% of the patients, which was extensive disease in 18%. The 2-year cumulative incidence of relapse was 21%. The relapse rate was higher in patients beyond CR1 or with intermediate two or high risk MDS (P = 0.02). The treatment-related mortality at day 100 was 28%. The 2-year estimated overall and disease-free survival was 36-34%, respectively. No difference in survival was seen between unrelated and related SCT.

High doses of transplanted CD34+ cells are associated with rapid T-cell engraftment and lessened risk of graft rejection, but not more graft-versus-host disease after nonmyeloablative conditioning and unrelated hematopoietic cell transplantation.

This report examines the impact of graft composition on outcomes in 130 patients with hematological malignancies given unrelated donor granulocyte-colony-stimulating-factor-mobilized peripheral blood mononuclear cells (G-PBMC) (n = 116) or marrow (n = 14) transplantation after nonmyeloablative conditioning with 90 mg/m(2) fludarabine and 2 Gy TBI. The median number of CD34(+) cells transplanted was 6.5 x 10(6)/kg. Higher numbers of grafted CD14(+) (P = 0.0008), CD3(+) (P = 0.0007), CD4(+) (P = 0.001), CD8(+) (P = 0.004), CD3(-)CD56(+) (P = 0.003), and CD34(+) (P = 0.0001) cells were associated with higher levels of day 28 donor T-cell chimerism. Higher numbers of CD14(+) (P = 0.01) and CD34(+) (P = 0.0003) cells were associated with rapid achievement of complete donor T-cell chimerism, while high numbers of CD8(+) (P = 0.005) and CD34(+) (P = 0.01) cells were associated with low probabilities of graft rejection. When analyses were restricted to G-PBMC recipients, higher numbers of grafted CD34(+) cells were associated with higher levels of day 28 donor T-cell chimerism (P = 0.01), rapid achievement of complete donor T-cell chimerism (P = 0.02), and a trend for lower risk for graft rejection (P = 0.14). There were no associations between any cell subsets and acute or chronic GVHD nor relapse/progression. These data suggest more rapid engraftment of donor T cells and reduced rejection rates could be achieved by increasing the doses of CD34(+) cells in unrelated grafts administered after nonmyeloablative conditioning.

Unilateral, Multifocal Fracture of Radial with Ipsilateral Midshaft Ulna Fracture - Two Such Unusual and Rarely Reported Cases.

INTRODUCTION: Diaphyseal fractures of both bones of the forearm are commonly encountered in clinical practice. Segmental radius shaft fractures are, however, less commonly seen. We hereby report two cases of segmental complex radius fracture with mid-shaft ulna fracture. Such type of cases are reported previously in children but rarely in adults. CASE REPORT: In case-1, comminuted radius shaft fracture was fixed with square nails and ulna was fixed with Recon plate. In case-2, plating was done for radius mid-shaft, K-wiring for distal radius, and ulna was stabilized with a square nail. Details of both cases aredescribed and alternative management options are discussed. CONCLUSION: To the best of our knowledge, a segmental fracture of the radius associated with ipsilateral mid-shaft fracture of the ulna in an adult has been rarely reported in the literature to date. Optimal management of such fracture configuration has not been outlined in the literature. Prompt surgical management of such a complex fracture resulted in a rapid, full and satisfactory functional recovery for our patient.

Hypercholesterolemia and its association with enhanced stem cell mobilization and harvest after high-dose cyclophosphamide+G-CSF.

High-dose chemotherapy with autologous peripheral blood SCT is a common treatment option in several hematological and non-hematological malignancies. So far, prediction of successful stem cell mobilization and harvest is limited. Just recently, hypercholesterolemia was shown to increase mobilization of hematopoietic progenitor cells into the peripheral circulation in mice. On the basis of these results, we performed a retrospective multivariate analysis incorporating a variety of clinical parameters in 83 patients following high-dose cyclophosphamide+G-CSF treatment. Interestingly, we found a significant positive correlation between stem cell mobilization and harvest for plasma cholesterol and lactate dehydrogenase (LDH) only. Patients with hypercholesterolemia showed a substantially higher median peripheral blood CD34(+)-peak (126 vs 47/µL, P=0.003), higher median number of harvested CD34(+)-cells/kg (9.6 vs 7.4 × 10(6)/kg, P<0.001) and a sufficient number for at least one SCT in a remarkably higher proportion (84.9 vs 52.9%, P=0.003) compared with patients with normal cholesterol levels.

Chemokine CXCL13 is overexpressed in the tumour tissue and in the peripheral blood of breast cancer patients.

The abilities of chemokines in orchestrating cellular migration are utilised by different (patho-)biological networks including malignancies. However, except for CXCR4/CXCL12, little is known about the relation between tumour-related chemokine expression and the development and progression of solid tumours like breast cancer. In this study, microarray analyses revealed the overexpression of chemokine CXCL13 in breast cancer specimens. This finding was confirmed by real-time polymerase chain reaction in a larger set of samples (n = 34) and cell lines, and was validated on the protein level performing Western blot, ELISA, and immunohistochemistry. Levels of CXCR5, the receptor for CXCL13, were low in malignant and healthy breast tissues, and surface expression was not detected in vitro. However, we observed a strong (P = 0.0004) correlation between the expressions of CXCL13 and CXCR5 in breast cancer tissues, indicating a biologically relevant role of CXCR5 in vivo. Finally, we detected significantly elevated serum concentrations of CXCL13 in patients with metastatic disease (n = 54) as compared with controls (n = 44) and disease-free patients (n = 48). In conclusion, CXCL13 is overexpressed within breast cancer tissues, and increased serum levels of this cytokine can be found in breast cancer patients with metastatic disease pointing to a role of CXCL13 in the progression of breast cancer, suggesting that CXCL13 might serve as a useful therapeutic target and/or diagnostic marker in this malignancy.

Allogeneic peripheral blood stem cell graft composition affects early T-cell chimaerism and later clinical outcomes after non-myeloablative conditioning.

We have studied the influence of cell subsets [CD34, CD3, CD4, CD8, CD14, CD20, natural killer (NK; CD3(-)/CD56(+)), NKT (CD3(+)/CD56(+)), DC1, and DC2 cells] of granulocyte colony-stimulating factor mobilized peripheral blood stem cells (PBSC) on early T-cell chimaerism and later clinical outcomes in 125 patients with haematological malignancies who received human leucocyte antigen (HLA)-matched related grafts after non-myeloablative conditioning. Conditioning consisted of 2 Gy total body irradiation (TBI) alone (n = 28), or 2 Gy TBI preceded by either 90 mg/m(2) fludarabine (n = 62) or planned autologous haematopoietic cell transplantation (HCT) (n = 35). Post-transplant immunosuppression included mycophenolate mofetil and ciclosporin. Multivariate analysis showed that higher numbers of grafted NK cells predicted higher early T-cell chimaerism (P = 0.03), while higher numbers of B cells were associated with better clinical outcomes and a higher risk for chronic graft-versus-host disease (P = 0.05). Higher numbers of CD14(+) cells were associated with worse overall survival (P = 0.03), while higher numbers of CD34(+) cells showed better survival (P = 0.03). The addition of fludarabine or autologous HCT predicted higher early T-cell chimaerism (P = 0.001), while advanced donor age predicted lower chimaerism (P < or = 0.02). Patients with aggressive diseases were at higher risk for relapse/disease progression, and shorter progression-free and overall survival (P < 0.01). These results suggest that the dosing of certain cellular subsets of PBSC products can influence important outcomes post-HCT after non-myeloablative conditioning.

Fibroblasts transformed by chemical carcinogens are sensitive to intercellular induction of apoptosis: implications for the control of oncogenesis.

The ability of neighbouring normal cells to inhibit proliferation of transformed cells is regarded as the classical mode of intercellular control of potential tumour cells. This mechanism, however, only controls the pool size of transformed cells, but does not impair their survival. We have recently shown that cells transformed by biological agents are subject to a novel control system: transforming growth factor beta (TGF-beta) induces normal cells to release factors that mediate apoptosis specifically in transformed cells. Here we show that cells transformed by chemical carcinogens are also subject to this dominant control mechanism. The number of foci induced by methylcholanthrene, N-methyl-N'-nitro-N-nitrosoguanidine or quercetin was significantly reduced when the cultures were treated with TGF-beta. Established lines of chemically transformed cells proved to be sensitive to induction of apoptosis by neighbouring normal cells in the presence of TGF-beta. This finding demonstrates that sensitivity to induction of apoptosis is a general feature of transformed cells, irrespective of the transforming agent. It is particularly relevant for chemical carcinogenesis. As transformed cells were shown to trigger induction of their own apoptosis, the acquisition of resistance to this process may be a central regulatory step in carcinogenesis in vitro and possibly also in vivo. This study may help to elucidate mechanisms that protect transformed cells at an early stage of tumour progression that has until now not been the focus of investigation.

Reactive oxygen species as mediators of the transformed phenotype.

Reactive oxygen species (ROS) are known to be involved in different pro- and anticarcinogenic mechanisms. However, their influence on the maintenance of the transformed phenotype has not been studied so far. Here we show that the anchorage-independent growth of transformed murine fibroblasts is inhibited by antioxidants and radical scavengers in a concentration-dependent and reversible manner. These agents also reduce TGF-beta-dependent stimulation of colony formation in soft agar, pointing to their specific interference with TGF-beta-triggered signal chains involved in the maintenance of the transformed state.

[Tumor oxygenation in combined whole body hyperthermia and polychemotherapy. Studies exemplified by recurrent carcinoma of the mouth cavity]. / Tumoroxygenierung unter kombinierter Ganzkörperhyperthermie und Polychemotherapie. Untersuchungen am Beispiel eines Rezidivkarzinoms der Mundhöhle.

BACKGROUND AND OBJECTIVE: Previous studies have reported synergistic effects of combined hyperthermia and chemotherapy and/or irradiation. The response to irradiation and chemotherapy of well-oxygenated and vascularized tumors generally is better than that of hypoxic tumors. Therefore, tumor oxygenation is recognized as an important predictive factor in the therapy of malignant tumors. In practice, the head and neck area remains outside of the hyperthermia chamber during whole-body hyperthermia. It was the aim of this study to evaluate if the head and neck region receives sufficient warmth and, if so, if tumor oxygenation increases accordingly. PATIENTS/METHODS: Whole-body hyperthermia, as heat radiation (Enthermics Medical Systems RHS-7500), was applied to the narcotised 60-year-old male patient with a local recurrence tumor pT3 pN2b M0 squamous cell carcinoma of the oral cavity. Tumor oxygenation and temperature were measured by LICOX catheters via one-point measurement during the entire hyperthermia treatment (3.5 h). Parallelly, chemotherapy (ifosfamide/Carboplatin) was given in four cycles (one cycle/month). RESULTS: With a latency of 10 min the increase of intratumoral temperature was comparable to temperatures achieved in the esophagus. The maximum intratumoral temperature was 41.8 degrees C. The average increase in tumor oxygenation was more than 100%. The clinical outcome in the case presented was a partial tumor remission (PR). CONCLUSIONS: During combined whole-body hyperthermia and polychemotherapy, tumor oxygenation is also significantly improved in the head and neck area, despite the fact that the head and neck area remained outside the hyperthermia chamber. The intratumoral temperature was comparable to esophageal and rectal temperatures.
