Gemcitabine combined with the monoclonal antibody nimotuzumab is an active first-line regimen in KRAS wildtype patients with locally advanced or metastatic pancreatic cancer: a multicenter, randomized phase IIb study.

BACKGROUND: This randomized study was designed to investigate the superiority of gemcitabine (gem) plus nimotuzumab (nimo), an anti-epidermal growth factor receptor monoclonal antibody, compared with gem plus placebo as first-line therapy in patients with advanced pancreatic cancer. PATIENTS AND METHODS: Patients with previously untreated, unresectable, locally advanced or metastatic pancreatic cancer were randomly assigned to receive gem: 1000 mg/m2, 30-min i.v. once weekly (d1, 8, 15; q29) and nimo: fixed dose of 400 mg once weekly as a 30-min infusion, or gem plus placebo, until progression or unacceptable toxicity. The primary end point was overall survival (OS), secondary end points included time to progression, overall response rate, safety and quality of life. RESULTS: A total of 192 patients were randomized, with 186 of them being assessable for efficacy and safety (average age 63.6 years). One-year OS/progression-free survival (PFS) was 34%/22% for gem plus nimo compared with 19%/10% for gem plus placebo (HR = 0.69; P = 0.03/HR = 0.68; P = 0.02). Median OS/PFS was 8.6/5.1 months for gem plus nimo versus 6.0/3.4 mo in the gem plus placebo group (HR = 0.69; P = 0.0341/HR = 0.68; P = 0.0163), with very few grade 3/4 toxicities. KRAS wildtype patients experienced a significantly better OS than those with KRAS mutations (11.6 versus 5.6 months, P = 0.03). CONCLUSION: This randomized study showed that nimo in combination with gem is safe and well tolerated. The 1-year OS and PFS rates for the entire population were significantly improved. Especially, those patients with KRAS wildtype seem to benefit. The study was registered as protocol ID OSAG101-PCS07, NCT00561990 and EudraCT 2007-000338-38.

Final efficacy and updated safety results of the randomized phase III BEATRICE trial evaluating adjuvant bevacizumab-containing therapy in triple-negative early breast cancer.

BACKGROUND: The purpose of this analysis was to assess the long-term impact of adding bevacizumab to adjuvant chemotherapy for early triple-negative breast cancer (TNBC). METHODS: Patients eligible for the open-label randomized phase III BEATRICE trial had centrally confirmed triple-negative operable primary invasive breast cancer (pT1a-pT3). Investigators selected anthracycline- and/or taxane-based chemotherapy for each patient. After definitive surgery, patients were randomized 1:1 to receive ≥4 cycles of chemotherapy alone or with 1 year of bevacizumab (5 mg/kg/week equivalent). Stratification factors were nodal status, selected chemotherapy, hormone receptor status, and type of surgery. The primary end point was invasive disease-free survival (IDFS; previously reported). Secondary outcome measures included overall survival (OS) and safety. RESULTS: After 56 months' median follow-up, 293 of 2591 randomized patients had died. There was no statistically significant difference in OS between treatment arms in either the total population (hazard ratio 0.93, 95% confidence interval [CI] 0.74-1.17; P = 0.52) or pre-specified subgroups. The 5-year OS rate was 88% (95% CI 86-90%) in both treatment arms. Updated IDFS results were consistent with the primary IDFS analysis. Five-year IDFS rates were 77% (95% CI 75-79%) with chemotherapy alone versus 80% (95% CI 77-82%) with bevacizumab. From 18 months after first study dose to study end, new grade ≥3 adverse events occurred in 4.6% and 4.5% of patients in the two arms, respectively. CONCLUSION: Final OS results showed no significant benefit from bevacizumab therapy for early TNBC. Late-onset toxicities were rare in both groups. Five-year OS and IDFS rates suggest that the prognosis for patients with TNBC is better than previously thought. CLINICALTRIALS.GOV: NCT00528567.

ABC3 Consensus Commented from the Perspective of the German Guidelines: Third International Consensus Conference for Advanced Breast Cancer (ABC3), Lisbon, 07. 11. 2015.

The Third International Consensus Conference for Advanced Breast Cancer ABC3 on the diagnosis and treatment of advanced breast cancer was held in Lisbon from 5 to 7 November 2015. This year the focus was the treatment of metastatic breast cancer (stage IV) - including the patient perspectives. Important topics were questions relating to quality of life, the care for long-term survivors as well as the management of disease-related symptoms and treatment-based side effects. The use of standardised tools to assess individual treatment success and the benefits of new substances were important points for discussion. The diagnosis and treatment of inoperable locally advanced breast cancer were discussed two years ago during the ABC2 consensus 1. A working group of German breast cancer experts commented on the results of the ABC panellists, paying particular attention to the German guidelines (AGO, S3, DGHO) on the diagnosis and treatment of breast cancer 2, 3, 4, 5 in Germany.

Biomarkers in Patients with Metastatic Breast Cancer and the PRAEGNANT Study Network.

Progress has been made in the treatment of metastatic breast cancer in recent decades, but very few therapies use patient or tumor-specific characteristics to tailor individualized treatment. More than ten years after the publication of the reference human genome sequence, analysis methods have improved enormously, fostering the hope that biomarkers can be used to individualize therapies and offer precise treatment based on tumor and patient characteristics. Biomarkers at every level of the system (genetics, epigenetics, gene expression, micro-RNA, proteomics and others) can be used for this. This has led to changes in clinical study designs, with drug developments often only focusing on small or very small subgroups of patients and tumors. The screening and registration of patients and their molecular tumor data has therefore become very important for the successful completion of clinical studies. This new form of medicine presents particular challenges for patients and physicians. Even in this new age of genome-wide analysis, the focus should still be on the patients' quality of life. This review summarizes recent developments and describes how the PRAEGNANT study network manages the aforementioned medical challenges and changes to create a professional infrastructure for patients and physicians.

Sequential therapies with sorafenib and sunitinib in advanced or metastatic renal cell carcinoma.

PURPOSE: To investigate whether patients with metastatic renal cell carcinoma benefit from sequential therapies with the tyrosine kinase inhibitors (TKIs) sorafenib and sunitinib. PATIENTS AND METHODS: A total of 89 patients were treated in nine German centres between 2002 and 2009. The TKI sequence started as first-, second- or third-line therapy after prior chemo- or immunotherapy. When progression was diagnosed, treatment was switched to the second TKI until further progression. RESULTS: Overall progression-free survival (PFS) of patients receiving sunitinib followed by sorafenib shows no statistically significant difference to patients receiving sorafenib followed by sunitinib (15.4 months vs. 12.1 months). The secondary use of sorafenib resulted in a median PFS of 3.8 months if the TKI sequence had been started as a first-line treatment and of 3.5 months if the TKI sequence had been started second-line treatment. The secondary use of sunitinib resulted in a median PFS of 3.4 and 4.0 months, respectively. OS was 28.8 months for all patients, without a statistically significant difference between the two groups. CONCLUSIONS: This study endorses the notion of a clinical benefit of the sequential use of sorafenib and sunitinib and supports observations from previous studies. In terms of the optimal succession of the two TKIs, the study does not allow a definite answer.

Breast cancer patients' expectations in respect of the physician-patient relationship and treatment management results of a survey of 617 patients.

BACKGROUND: The following study was conducted to explore patients' information needs and preferences with a special focus on doctor-patient communication. PATIENTS AND METHODS: A 62-item questionnaire developed by a multidisciplinary team and validated in a phase-I study was given to breast cancer patients via the Internet (homepage) or in a hard copy version. RESULTS: A total of 617 patients responded, 552 on line and 65 via the hard copy questionnaire. The median age of the on-line group was 47 (21-85) and 55 (40-92) in the hard copy group. Sixty-five per cent of the patients were treated with the intention of achieving a cure and 35% of the patients had metastatic disease. The median length of the consultation communicating the information 'You have breast cancer' was 15 min (0-300). The most effective and patient-relevant source of information about the disease and the treatment options was consultation with the physician (84%). When asked to suggest areas for improvement, patients' most common answers were: more complementary therapies should be offered by the physician (54%); physicians should take more time to explain things (51%); and cooperation between the physicians involved in the patient's care should be improved (39%). The questions most relevant to patients were: 'Am I getting the right therapy?' (89%); 'How many patients with my condition does my doctor treat?' (46%) and 'Can I be enrolled into a trial?' (46%). An independent second opinion centre was desired by 94% of the respondents but only 20% knew of any such resource. CONCLUSIONS: This study underlines the need to give patients with breast cancer the full details on treatment options and cancer management. The results provide a suitable basis for a broader interdisciplinary discussion of the patient-physician relationship and should be useful in generating hypotheses for subsequent prospective studies.

[Breast cancer: analysis of treatment quality in Germany 2004: retrospective survey by Arbeitsgemeinschaft Gynäkologische Onkologie (AGO)]. / Das Mammakarzinom: Versorgungslage und Therapiequalität in Deutschland 2004. Eine retrospektive Analyse der Organgruppe Mamma der Arbeitsgemeinschaft Gynäkologische Onkologie (AGO).

The Organgruppe Mamma der Arbeitsgemeinschaft Gynaekologische Onkologie (AGO) conducted a nationwide 3-phase analysis of the care structure and standard of therapy given to patients with breast cancer from 2002 (4th quarter) to 2004 (4th quarter). The analysis includes 1069 patients from 257 institutions; 34% with early breast cancer and 66% with metastatic disease. No reliable data on the pattern of care of these patients have been published to date in Germany. The extent to which national and international therapy recommendations were implemented in routine clinical practice was unclear. Evaluation of the data shows that treatment based on the guidelines is now being implemented very reliably in certain sectors. This is of particular relevance to the pattern of adjuvant treatment in early breast cancer. At that time 68 % of the patients received an anthracyclin based chemotherapy and in addition 18% received an anthracycline and taxane based chemotherapy. Participation in clinical trials peaked with 30% in the neoadjuvant setting. The problem with metastatic breast cancer is the complexity of the interdisciplinary treatment involved. The present analysis conducted by the AGO was the first attempt to analyse the treatment given to metastatic patients and to systematise the approach to treatment. The fundamental problem remains, irrespective of the stage of the tumour, namely that too few patients are treated in randomised clinical studies.

Recombinant human granulocyte-macrophage colony-stimulating factor and low-dose cytosine-arabinoside in the treatment of patients with myelodysplastic syndromes. A phase II study.

As part of a multicenter trial 12 patients with myelodysplastic syndromes (MDS) were treated with 14-day-cycles of recombinant human granulocyte-macrophage colony-stimulating factor (rhGM-CSF; 250 micrograms/m2 day s.c.). In addition, all patients received 20 mg/m2/day s.c. cytosine-arabinoside (Ara-C) 12 h after GM-CSF except for patients suffering from refractory anemia (RA) according to FAB classification. Courses were repeated after 4 weeks. In 11 evaluable patients, results according to FAB-classified MDS were as follows: RA, 1/2 response (R), 1/2 stable disease (SD); RAEB, 2/3 R, 1/3 SD; RAEB-T, 1/6 CR, 1/6 PR, 2/6 R, 2/6 progression; CMML, 1/2 SD. In 2 patients with RAEB-T, overt acute myeloid leukemia was observed 2 and 10 weeks after initiation of treatment. With few exceptions, treatment resulted in a prompt increase in granulocytes and eosinophiles. This was associated with improvement of infectious complications. Increases in red cells and platelets occurred variably and was apparently associated with responses of the underlying disease. Dose limiting side effects consisted of fever, severe fatigue and dolent local reactions at the site of GM-CSF injection. In addition, nausea and diarrhoea occurred frequently. Less often, respiratory and cardiovascular side effects were encountered. In summary, GM-CSF +/- Ara-C in MDS results in objective remission with manageable toxicity. Conceivably, this regimen will serve as a base for future treatment strategies against MDS.

[Factitious disease. Observations on 44 cases at a medical clinic and recommendation for a subclassification]. / Vorgetäuschte Krankheit. Beobachtungen bei 44 Fällen aus einer Medizinischen Klinik und Vorschlag einer Subklassifikation.

From 1971 to 1985, 44 cases of self-induced factitious disorders were observed in the Medical Department of a University Hospital. The diseases were often severe, one patient even died. The various symptoms and diseases presented by the patients, the methods of producing them, and the diagnostic and therapeutic aspects of these cases are described. Patients were analysed with regard to age, sex, profession, psychosocial adaptation, number and duration of hospitalisations, presentation of complaints, behaviour on the ward, relation to the doctor, self-destructive tendencies, readiness to suffer and possible motivations. According to the criteria of the DSM-III, seven patients were malingerers (DSM-III: V 65.20) and 37 had a "chronic factitious disorder with physical symptoms" (DSM-III: 301.51). However, the findings in the patients of the latter group strongly suggest that they form an extremely heterogeneous population. Therefore we propose a subclassification of the DSM-III category 301.51 as follows: Type A. Muenchausen syndrome in the proper sense; dramatic deception of mainly acute illness; pseudologia fantastica; social maladaptation, chaotic life situations; many, mostly short hospitalisations; many interventions; at first well adapted, later hostile; mostly men. Type B. Self-induced, mainly chronic illness; behaviour adequate, highly compliant; often little emotion, contrasting with the sometimes severe illness; socially adapted; history remarkably blank with regard to psychosocial stress; several often longlasting hospitalisations and many interventions; almost exclusively younger women from (para-)-medical professions. Type C. Willfull interference with the healing of wounds, cutaneous ulcers, abscesses or dermatological artefacts; history with marked personal losses or severe chronic medical problems; at first well adapted, later hostile, passive/aggressive; women prevail. A conversion syndrome (DSM-III: 300.11) was not observed. In contrast to malingering, the basis of the disorder in types A, B and C is unconscious in origin, thus similar to the conversion syndrome. Contrary to the latter, however, the production of physical symptoms is under voluntary control. The proposed subclassification represents a hypothesis for testing which might facilitate the analysis of the basic personality disorder, so far lacking. The investigation of the psychopathology of these patients and their treatment is difficult if not impossible because most refuse psychiatric exploration and therapy. Consequently follow-up studies and data on the prognosis are rare.
