Quality of life and quality-adjusted survival (Q-TWiST) in patients receiving dose-intensive or standard dose chemotherapy for high-risk primary breast cancer

Quality of life (QL) is an important consideration when comparing adjuvant therapies for early breast cancer, especially if they differ substantially in toxicity. We evaluated QL and Q-TWiST among patients randomised to adjuvant dose-intensive epirubicin and cyclophosphamide administered with filgrastim and progenitor cell support (DI-EC) or standard-dose anthracycline-based chemotherapy (SD-CT). We estimated the duration of chemotherapy toxicity (TOX), time without disease symptoms and toxicity (TWiST), and time following relapse (REL). Patients scored QL indicators. Mean durations for the three transition times were weighted with patient reported utilities to obtain mean Q-TWiST. Patients receiving DI-EC reported worse QL during TOX, especially treatment burden (month 3: P<0.01), but a faster recovery 3 months following chemotherapy than patients receiving SD-CT, for example, less coping effort (P<0.01). Average Q-TWiST was 1.8 months longer for patients receiving DI-EC (95% CI, -2.5 to 6.1). Q-TWiST favoured DI-EC for most values of utilities attached to TOX and REL. Despite greater initial toxicity, quality-adjusted survival was similar or better with dose-intensive treatment as compared to standard treatment. Thus, QL considerations should not be prohibitive if future intensive therapies show superior efficacy.

Long-term followup results of 1 cycle of adjuvant bleomycin, etoposide and cisplatin chemotherapy for high risk clinical stage I nonseminomatous germ cell tumors of the testis

PURPOSE: We evaluated the long-term outcome after 1 cycle of adjuvant modified bleomycin, etoposide and cisplatin chemotherapy in patients who underwent orchiectomy for high risk clinical stage I nonseminomatous germ cell tumor of the testis. MATERIALS AND METHODS: Between 1995 and 1999 a consecutive series of 44 patients underwent orchiectomy for clinical stage I nonseminomatous germ cell tumor of the testis, followed by a single postoperative cycle of adjuvant modified bleomycin, etoposide and cisplatin for vascular or lymphatic tumor invasion, and/or a predominance (50% or greater) of embryonal carcinoma. RESULTS: Four of the 44 patients were excluded from analysis. Of the patients 35 had no evidence of disease at a median followup of 99 months (range 60 to 134). One patient with progression after 13 months showed complete remission after 3 cycles of salvage bleomycin, etoposide and cisplatin chemotherapy but he died of pneumonia 4 weeks after the third course. Two patients underwent orchiectomy for contralateral testis cancer at 18 and 42 months, respectively, followed by an additional 3 cycles of adjuvant chemotherapy. They remained relapse-free for 4 and 92 months, respectively. The former patient was lost to followup after 4 months. Two other patients were disease-free at 10 and 31 months, respectively, and were lost to followup thereafter. Late side effects were tinnitus in 3 patients and involuntary childlessness in 3, of whom 2 had cryptorchidism of the contralateral testis. Nine patients fathered children. CONCLUSIONS: One cycle of bleomycin, etoposide and cisplatin effectively decreases the risk of relapse in patients with high risk stage I nonseminomatous germ cell tumor of the testis. It has minimal side effects and can be a valuable alternative to retroperitoneal lymph node dissection.

[Localised rhabdomyosarcoma of the extremities in children and adolescents: results of the French experience]

PATIENTS AND METHODS: Forty-six patients with localised RMS of the limbs entered the MMT 89 and 95 study in France. We studied potential risk factors that were predictive of relapse and survival to propose a therapeutic approach of surgery and radiotherapy appropriate to the risk of relapse. RESULTS: Median age at diagnosis was 6.5 years [9 months to 15.5 years]. At time of diagnosis, 43% had marginal surgery and only 13% radical intervention. Primary re-excision was performed in 12% of the patients. All patients received chemotherapy, 43% had second look surgery and 37% received radiotherapy. Fifty-four percent of all tumors relapsed: local relapse 36%, nodes l8%, metastatic 40%, local and metastatic 16%. Estimated overall 5-year event-free survival (EFS) and overall survival (OS) were 40 and 57%, respectively. CONCLUSIONS: Prognosis of RMS of the limbs is bad but only 37% of the patients had radiotherapy. We could define patients with very high risk among those with limbs RMS as nodal involvement (5 years overall survival OS 22%), alveolar histology (OS 38%) and site of hand and foot (4 survivors out of 10 patients). In further studies, these patients should be treated even more aggressive with early surgery followed by re-excision if necessary, chemotherapy including alkylating agents and systematic radiotherapy.

Non-classical karyotypic features in relapsed childhood B-cell precursor acute lymphoblastic leukemia

Karyotype analysis of acute lymphoblastic leukemia (ALL) at diagnosis has provided valuable prognostic markers for treatment stratification. However, reports of cytogenetic studies of relapsed ALL samples are limited. We compared the karyotypes from 436 nonselected B-cell precursor ALL patients at initial diagnosis and of 76 patients at first relapse. We noticed a relative increase of karyotypes that did not fall into the classic ALL cytogenetic subgroups (high hyperdiploidy, t(12;21), t(9;22), 11q23, t(1;19), <45 chromosomes) in a group of 29 patients at relapse (38%) compared to 130 patients at presentation (30%). Non-classical cytogenetic aberrations in these 29 patients were mostly found on chromosomes 1, 2, 7, 9, 13, 14, and 17. We also describe six rare reciprocal translocations, three of which involved 14q32. The most frequent abnormalities were found in 9p (12/29 cases) and were associated with a marked decrease in the duration of the second remission, but not of the probability of 10-year event-free survival after relapse treatment. From 29 patients with non-classical cytogenetic aberrations, only 8 (28%) had been stratified to a high risk-arm on the first treatment protocol, suggesting that this subgroup might benefit from the identification of new prognostic markers in future studies.

Interaction between rheumatoid arthritis and pregnancy: correlation of molecular data with clinical disease activity measures

OBJECTIVE: The factors that induce remission of RA during pregnancy and the relapse occurring after delivery remain an enigma. In a previous study, we investigated gene-expression profiles of peripheral blood mononuclear cells (PBMC) in patients with RA and healthy women in late pregnancy and postpartum. Profiles of samples from both groups were similar in late pregnancy with elevated monocyte and decreased lymphocyte signatures. Postpartum, in RA PBMC the high level of monocyte transcripts persisted. Further increase was observed in adhesion, migration and signalling processes related to monocytes but also in lymphocytes despite similar clinical activity due to intensified drug treatment. This prompted us to investigate correlations between clinical parameters of disease activity and gene profiles. METHODS: Transcriptome data were correlated with RADAI, CRP, monocyte and lymphocyte counts. Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway annotations, monocytes and lymphocytes signatures were used as reference information. RESULTS: Comparative analysis of PBMC expression profiles from RA patients during and after pregnancy with RADAI and CRP revealed a correlation of these disease activity parameters predominantly with monocyte transcripts. Genes related to cellular programs of adhesion, migration and response to infections were upregulated. Comparing clinically active and not-active RA patients postpartum revealed a cluster of 19 genes that could also identify active disease during pregnancy. CONCLUSION: The data suggest that an increase of the RADAI and an elevation of CRP is a consequence of molecular activation of monocytes. Furthermore, they indicate that molecular activation of T lymphocytes may remain clinically unrecognized postpartum. It is conceivable that a set of 19 genes may qualify as molecular disease activity marker.

[Perianal erythema in a child--group A streptococci?!]

Perianal streptococcal dermatitis is a common disease. The typical clinical picture includes perianal erythema, pruritus, painful defaecation and bloody stools. The diagnosis is made by a swab taken from the affected skin with bacterial culture. Therapy consists of penicillin for 10 days. Screening for affected persons in contact with the patient is indicated because perianal streptococcal dermatitis is known to be highly contagious. Relapse is common and therefore follow-up visits are recommended. In case of relapse, a first or second generation cephalosporin may be considered.

Outcome of treated anogenital intraepithelial neoplasia among human immunodeficiency virus-infected women

OBJECTIVE: To determine characteristics and clinical course of high-grade anogenital intraepithelial neoplasia (AIN) in human immunodeficiency virus (HIV)-infected women. STUDY DESIGN: HIV-positive women with biopsy-proven high-grade (II and III) vulvar (VIN), vaginal (VAIN) or perianal intraepithelial neoplasia (PAIN) were identified in the electronic databases of 2 colposcopy clinics. RESULTS: A total of 31 patients were identified from 1992 to 2007, of which 30 had a mean follow-up of 47.7 months (SD = 46.0; range, 2.6-166.2). Of the patients, 77.4% had VIN, 12.9% VAIN and 9.7% PAIN at first diagnosis. Age at diagnosis of IN was 36.2 years (SD +/- 5.2; range, 23.5-47.0). Ninety percent of patients received antiretroviral therapy at first diagnosis of IN; 65% (13 of 20) of patients with a follow-up of > 2 years required a second treatment, and 2 developed invasive vulvar cancer (10%). CONCLUSION: AIN among HIV-positive women shows a high relapse rate despite treatment modality used and a substantial invasive potential.

[Follow-up after malignant tumours of the uterus (cancer of the uterine corpus / cervical cancer)]

Malignant uterine tumours can affect the corpus or the cervix. The endometrial carcinoma with its different histological subtypes counts for most of the malignomas of the uterine body. But the rare category of uterine sarcomas (carcinosarcomas, leiomyosarcomas as well as endometrial stromal sarcomas) also belongs to this group. Cervical cancer presents an own entitity, regarding both histology and therapeutic options. Endometrial cancer is the most common genital malignoma in Northern Europe and North America. Histologically, the endometrial cancer can be subdivided in two groups: type I is hormonal sensitive and well differentiated, type II represents an undifferenciated aggressive tumour with poor prognosis. In general, the patient is elderly. Due to the main symptom - abnormal vaginal bleeding - endometrial cancer is detected in an early stage in about 75% of all patients. First choice in therapy is stage related surgery. Follow-up schemes have not proved yet to improve survival, therefore clear guidelines are missing. National and international groups recommend regular follow-up visits to detect the early vaginal vault relapse which is curable. Cervical cancer is mainly a squamous cell carcinoma and oncogenic Human Papilloma Virus (HPV) associated. Surgery is only indicated up to stage IIA, advanced stages should be treated by radio-chemotherapy. Several studies have shown that follow-up visits can improve survival rates. Intention is the detection of the curable local relapse.

Using PSA to guide timing of androgen deprivation in patients with T0-4 N0-2 M0 prostate cancer not suitable for local curative treatment (EORTC 30891)

OBJECTIVE: EORTC trial 30891 compared immediate versus deferred androgen-deprivation therapy (ADT) in T0-4 N0-2 M0 prostate cancer (PCa). Many patients randomly assigned to deferred ADT did not require ADT because they died before becoming symptomatic. The question arises whether serum prostate-specific antigen (PSA) levels may be used to decide when to initiate ADT in PCa not suitable for local curative treatment. METHODS: PSA data at baseline, PSA doubling time (PSADT) in patients receiving no ADT, and time to PSA relapse (>2 ng/ml) in patients whose PSA declined to <2 ng/ml within the first year after immediate ADT were analyzed in 939 eligible patients randomly assigned to immediate (n=468) or deferred ADT (n=471). RESULTS: In both arms, patients with a baseline PSA>50 ng/ml were at a>3.5-fold higher risk to die of PCa than patients with a baseline PSA12 mo. Time to PSA relapse after response to immediate ADT correlated significantly with baseline PSA, suggesting that baseline PSA may also reflect disease aggressiveness. CONCLUSIONS: Patients with a baseline PSA>50 ng/ml and/or a PSADT<12 mo were at increased risk to die from PCa and might have benefited from immediate ADT, whereas patients with a baseline PSA<50 ng/ml and a slow PSADT (>12 mo) were likely to die of causes unrelated to PCa, and thus could be spared the burden of immediate ADT.

[Lower eyelid reconstruction of traumatically caused cicatricial entropion with amniotic membrane or mucosal membrane grafts]

BACKGROUND: A retrospective evaluation was undertaken of eyelid reconstruction with amniotic membrane or oral mucosal membrane transplantation in patients with lower lid cicatricial entropion after orbital surgery. PATIENTS AND METHODS: Seven patients (four women) were treated with a scar tissue dissection and an amniotic membrane or mucosal membrane transplantation between 2003 and 2006 (Five amniotic membrane grafts and two oral mucosal membrane grafts). In selected cases additional procedures like a lateral tarsal strip operation, a tarsal fracture, or the reinsertion of the lower lid retractors were performed. RESULTS: All patients showed a favourable postoperative result with a good anatomic correction of the entropion and a regression of the preoperative disturbances. All the grafts took well. Two patients had to be reoperated twice and one patient three times as a result of a relapse of the cicatricial entropion. However, as well in these patients the anatomical and functional result was favourable at the end. CONCLUSIONS: The difficult scar dissection with the subsequent amniotic membrane or oral mucosal membrane transplantation seems to be an appropriate procedure to reconstruct complicated cicatricial entropion after orbital surgery.

Das Burnout-Syndrom: eine medizinische Perspektive

The burnout syndrome is a heterogeneous concept mostly understood as a complex of symptoms, primarily exhaustion, in response to prolonged emotional and interpersonal stress at work. The prevalence of burnout is considerably high in Swiss primary care physicians. In spite of its vague definition, burnout is a serious stress disease with many associated medical problems and high economic costs. Previous recommendations for the psychosomatic management of patients with functional somatic syndromes also apply to burnout treatment. These are complemented by more specific interventions targeting job stress related factors. Relapse prevention focuses on early recognition of warning signs and is an ongoing process.

IgG subclass distribution of anti-ADAMTS13 antibodies in patients with acquired thrombotic thrombocytopenic purpura

BACKGROUND: ADAMTS13-neutralizing IgG autoantibodies are the major cause of acquired thrombotic thrombocytopenic purpura (TTP). OBJECTIVE: To analyze the IgG subclass distribution of anti-ADAMTS13 antibodies and a potential relationship between subclass distribution and disease prognosis. METHODOLOGY: An enzyme-linked immunosorbent assay-based method was used to quantify the relative amounts of IgG subclasses of anti-ADAMTS13 antibodies in acquired TTP plasma. RESULTS: IgG(4) (52/58, 90%) was the most prevalent IgG subclass in patients with acquired TTP, followed by IgG(1) (52%), IgG(2) (50%), and IgG(3) (33%). IgG(4) was found either alone (17/52) or with other IgG subclasses (35/52). IgG(4) was not detected in 10% of the patients. There was an inverse correlation between the frequency and abundance of IgG(4) and IgG(1) antibodies (P < 0.01). Patients with high IgG(4) levels and undetectable IgG(1) are more prone to relapse than patients with low IgG(4) levels and detectable IgG(1). CONCLUSIONS: All IgG subclasses of anti-ADAMTS13 antibodies were detected in patients with acquired TTP, with IgG(4), followed by IgG(1), antibodies dominating the anti-ADAMTS13 immune response. Levels of IgG(4) could be useful for the identification of patients at risk of disease recurrence.

Stability after bilateral sagittal split osteotomy advancement surgery with rigid internal fixation: a systematic review

PURPOSE: The purpose of this systematic review was to evaluate horizontal relapse and its causes in bilateral sagittal split advancement osteotomy (BSSO) with rigid internal fixation of different types. MATERIALS AND METHODS: A search of the literature was performed in the databases PubMed, Ovid, Cochrane Library, and Google Scholar Beta. From 488 articles identified, 24 articles were finally included. Six studies were prospective, and 18 were retrospective. The range of postoperative study records was 6 months to 12.7 years. RESULTS: The short-term relapse for bicortical screws was between 1.5% and 32.7%, for miniplates between 1.5% and 18.0%, and for bioresorbable bicortical screws between 10.4% and 17.4%, at point B. The long-term relapse for bicortical screws was between 2.0% and 50.3%, and for miniplates between 1.5% and 8.9%, at point B. CONCLUSIONS: BSSO for mandibular advancement is a good treatment option for skeletal Class II, but seems less stable than BSSO setback in the short and long terms. Bicortical screws of titanium, stainless steel, or bioresorbable material show little difference regarding skeletal stability compared with miniplates in the short term. A greater number of studies with larger skeletal long-term relapse rates were evident in patients treated with bicortical screws instead of miniplates. The etiology of relapse is multifactorial, involving the proper seating of the condyles, the amount of advancement, the soft tissue and muscles, the mandibular plane angle, the remaining growth and remodeling, the skill of the surgeon, and preoperative age. Patients with a low mandibular plane angle have increased vertical relapse, whereas patients with a high mandibular plane angle have more horizontal relapse. Advancements in the range of 6 to 7 mm or more predispose to horizontal relapse. To obtain reliable scientific evidence, further short-term and long-term research into BSSO advancement with rigid internal fixation should exclude additional surgery, ie, genioplasty or maxillary surgery, and include a prospective study or randomized clinical trial design with correlation statistics.

Activation of the unfolded protein response is associated with favorable prognosis in acute myeloid leukemia

PURPOSE: The unfolded protein response is triggered by the accumulation of misfolded proteins within the endoplasmic reticulum. Previous studies suggest that the unfolded protein response is activated in some cancer cell lines and involved in tumor development. The role of the unfolded protein response during leukemogenesis is unknown thus far. EXPERIMENTAL DESIGN: Here, we assessed the induction of key effectors of the unfolded protein response in leukemic cells at diagnosis of 105 acute myeloid leukemia (AML) patients comprising all subtypes. We determined the formation of the spliced variant of the X-box-binding protein 1 (XBP1) mRNA, as well as expression levels of calreticulin, GRP78, and CHOP mRNA. RESULTS: The formation of the spliced variant of XBP1s was detectable in 16.2% (17 of 105) of AML patients. Consistent with activated unfolded protein response, this group also had significantly increased expression of calreticulin, GRP78, and CHOP. AML patients with activated unfolded protein response had lower WBC counts, lactate dehydrogenase levels, and more frequently, secondary AML. The incidence of fms-related tyrosine kinase 3 (FLT3) mutations was significantly lower in patients with activated unfolded protein response. In addition, an association was observed between activated unfolded protein response and deletion of chromosome 7. Finally, the clinical course of AML patients with activated unfolded protein response was more favorable with lower relapse rate (P = 0.0182) and better overall (P = 0.041) and disease-free survival (P = 0.022). CONCLUSIONS: These results suggest that the unfolded protein response is activated in a considerable subset of AML patients. AML patients with activated unfolded protein response present specific clinical characteristics and a more favorable course of the disease.

MET Y1253D-activating point mutation and development of distant metastasis in advanced head and neck cancers

We investigated if the MET-activating point mutation Y1253D influences clinical outcomes in patients with advanced squamous cell carcinoma of the head and neck (HNSCC). The study population consisted of 152 HNSCC patients treated by hyperfractionated radiotherapy alone or concomitant with chemotherapy between September 1994 and July 2000. Tumors were screened for the presence of the MET-activating point mutation Y1253D. Seventy-eight patients (51%) received radiotherapy alone, 74 patients (49%) underwent radiotherapy concomitant with chemotherapy. Median patient age was 54 years and median follow-up was 5.5 years. Distant metastasis-free survival, local relapse-free survival and overall survival were compared with MET Y1253D status. During follow-up, 29 (19%) patients developed distant metastasis. MET Y1253D was detected in tumors of 21 out of 152 patients (14%). Distant metastasis-free survival (P = 0.008) was associated with MET Y1253D. In a multivariate Cox regression model, adjusted for T-category, only presence of MET Y1253D was associated with decreased distant metastasis-free survival: hazard ratio = 2.5 (95% confidence interval: 1.1, 5.8). The observed association between MET Y1253D-activating point mutation and decreased distant metastasis-free survival in advanced HNSCC suggests that MET may be a potential target for specific treatment interventions.
