Follow-up Reality for Breast Cancer Patients - Standardised Survey of Patients and Physicians and Analysis of Treatment Data.

Introduction: Currently, about 360 000 breast cancer patients who could, after completion of their primary therapy, take advantage of follow-up options are living in Germany. Up to now very little is known about the extent to which the available options are used and as to how the follow-up reality is experienced and evaluated. Thus, an explorative examination among the patients and their physicians was undertaken. Patients and Methods: All patients who underwent surgery in a certified breast centre between 2007 and 2013 received a standardised questionnaire; at the same time the physicians responsible for the follow-up were invited to answer a standardised questionnaire. Results: 920 patients (response rate: 61 %) with a median age of 65 years (32-95) could be analysed. 99 % of the participants stated that they regularly attended follow-ups. The personal contact with the physician (mean value: 4.4) and the reassurance that the cancer disease had not recurred (mean value: 4.5) were described on a scale of 0 to 5 to be two of the most important factors of the follow-up. Deficits were expressed with regard to psychosocial care (70 %) and the perception and treatment of physical complaints (55 %). In addition, 105 physicians returned completed questionnaires (response rate: 12 %). For asymptomatic patients the physicians performed the following examinations most frequently: anamnesis (92 %), physical examination (87 %) as well as laboratory tests (63 %) and tumour marker determinations (40 %). Conclusion: On the whole it became clear that the vast majority of the patients took advantage of the follow-up options. From the patient's perspective the importance of the follow-up lies in contact to the physician and the comforting assurance that the breast cancer has not relapsed. Deficits are seen in the psychosocial care and the perception and treatment of physical impairments. Not recommended examinations were employed by a significant proportion of the surveyed physicians.

[Immunoglobulin substitution in patients with indolent non-Hodgkin's lymphoma]. / Immunglobulin-Substitution bei Patienten mit indolenten Non-Hodgkin-Lymphomen.

BACKGROUND: Infections are major complications in chronic lymphoproliferative disorders, among them indolent non-Hodgkin's lymphoma (iNHL) including chronic lymphocytic leukemia, follicular lymphoma and multiple myeloma.We report on a retrospective cohort analysis of outpatients with indolent non-Hodgkin's lymphoma who were treated in an oncology / hematology group practice and received intravenous polyvalent immunoglobulin G (IVIG) as supportive care. The aim was to describe the treated iNHL population, the course of therapy and the effects of IVIG administrations on the levels of immunoglobulin G (IgG), the incidence of infections and the survival time. PATIENTS AND METHOD: 57 patients with secondary iNHL antibody deficiencies (n = 46) or IgG subclass deficiencies (n = 11) who received IVIG substitution were included. Patients received median 11 IVIG doses with a mean dose of 28 g over a period of median 9.5 months. RESULTS: Mean IgG levels increased with IVIG substitution at about twice and then remained within the normal range. The incidence of infections decreased in 46 % of treated patients. Effects on survival could not be observed. Median overall survival was in the group of substituted patients 124 months (range 7-124), the control group had a median survival time of 96 months (range 3-129) (p = 0.537). CONCLUSION: IgG levels should be reviewed during IVIG substitution on a regular basis and dosage and intervals should be adjusted individually.

Evaluation of psychosocial distress in patients treated in a community-based oncology group practice in Germany.

BACKGROUND: Systematic evaluation of psychosocial distress in oncology outpatients is an important issue. We assessed feasibility and benefit of standardized routine screening using the Distress Thermometer (DT) and Problem List (PL) in all patients of our community-based hematooncology group practice. PATIENTS AND METHODS: One thousand four hundred forty-six patients were screened between July 2008 and September 2008. Five hundred randomly selected patients were sent a feedback form. RESULTS: The average distress level was 4.7, with 37% indicating a distress level >5. Patients with nonmalignant diseases (81% autoimmune diseases or hereditary hemochromatosis) showed the highest distress level of 5.2. Most distressed were patients who just learned about relapse or metastases (6.4), patients receiving best supportive care (5.4) and patients receiving adjuvant antihormonal therapy (5.4). Ninety-seven percent of patients appreciated to speak to their doctor about their distress. Fifty-six percent felt better than usual after this consultation. CONCLUSION: DT and PL are feasible instruments to measure distress in hematooncology outpatients receiving routine care. DT and PL are able to improve doctor-patient communication and thus should be implemented in routine patient care. The study shows that distress is distributed differently between individuals, disease groups and treatment phases.

The impact of new treatment options for advanced colorectal cancer on routine care: results of a retrospective analysis of 206 consecutive patients treated in a community-based oncology group practice in Germany.

Due to necessary selection criteria, the results obtained in clinical trials may not reflect the actual impact of current treatment options for unselected general populations. We analysed the treatment modalities and the outcome in 206 consecutive patients with advanced colorectal cancer who started treatment between 1/1999 and 11/2004. The median age of this cohort was 66 years (range 30-87) and 39 patients (19%) were ≥ 75 years old. First-line treatment consisted of low-dose bolus 5-fluorouracil and folinic acid regimens in 68 patients (33%), weekly 24-h 5-fluorouracil infusion and folinic acid in 36 patients (17%), weekly 24-h 5-fluorouracil infusion plus oxaliplatin or irinotecan in 60 patients (29%), capecitabine regimens in 22 patients (11%), monotherapy with oxaliplatin or irinotecan in six patients (3%) and other regimens in 14 patients (7%). A total of 166 patients (81%) received a second-line treatment and third-line chemotherapy was given to 122/206 patients (59%). With a minimum follow-up of 18 months, the median survival of the cohort is 21 months (range 1-85) and 17 months (range 3-57) for patients ≥ 75 years. We conclude that the increased survival seen in prospective studies can be transferred to routine care for unselected patients with advanced colorectal cancer.

[Lymphomas: new therapeutic options]. / Lymphomverdacht. Wie gehen Sie vor, welche Chancen hat ihr Patient?

Malignant lymphomas are differentiated clinically, morphologically and molecular-biologically, into aggressive (formerly high-grade malignant) and indolent (formerly low-grade malignant) lymphomas. In the meantime, virtually all patients can be diagnosed and treated on an ambulatory basis. The introduction of the monoclonal antibody rituximab (R) in combination with chemotherapeutic agents, has led to the development of highly potent forms of chemoimmunotherapy. In the case of aggressive lymphomas, R-CHOP has been shown to be significantly superior to CHOP alone, both in elderly and younger patients. In stage III and IV indolent (follicular) lymphomas, rituximab/chemotherapy combinations achieve response rates in excess of 90%, and prolonged progression-free survival rates which, for the first time hold out hope of a cure. Monoclonal antibodies that can be coupled to radioisotopes open up new possibilities for potent radioimmunotherapy which look promising for effecting a cure or long-lasting palliation in additional proportion of the patients.

Outpatient therapy in metastatic breast cancer. A retrospective study of 90 patients treated in an oncology group practice.

BACKGROUND: Whenever possible, treatment of breast cancer should be performed in an outpatient setting, but only few data about patients being treated exclusively on an outpatient basis are available. PATIENTS AND METHODS: A retrospective analysis was performed in 90 unselected patients who were treated consecutively in our oncology group practice between 6/95 and 8/99. RESULTS: Median age at detection of metastases was 55 years (30-90) and performance status ranged from 0 to 2. 83 patients (92.2%) received chemotherapy, 7 (7.8%) received endocrine therapy only. CMF was used in 27.7%, anthracyclines in 71.1% and taxanes in 43.3%. 855 chemotherapy cycles were performed and the observed toxicity was mild. Reversible grade 3 and 4 hematotoxicity was seen after 27 cycles (3.2%). Neurotoxicity or mucositis grade 3 and 4 were seen in 6 patients (6.6%). Therapy-associated hospitalization occurred in 1 patient thrice due to febrile neutropenia. Complete remissions were seen in 5 patients (5.6%) during first-line therapy. Median survival of the whole cohort until the end of the follow-up period (2/03) was 28 months (2-259). Overall survival after 1, 2, 3 and 5 years was 83, 56, 33 and 18% respectively. 50% could die at home. CONCLUSIONS: Treatment of metastatic breast cancer can be performed with minimal toxicity and a high patient acceptance in the outpatient setting. Overall survival and median survival are comparable to historical results achieved in specialized academic hospitals. Hospitalization could be avoided in the majority of patients and half of them could die at home.

Palliative treatment of advanced pancreatic carcinoma in community-based oncology group practices.

This study was aimed at evaluating the feasibility, effectiveness, and toxicity of palliative chemotherapy/supportive care in patients with advanced pancreatic cancer being treated on an outpatient basis. A retrospective analysis was performed on 127 consecutive, unselected patients with advanced pancreatic cancer in four community-based oncology group practices. Median age was 63 years and WHO performance status ranged from 0 to 3. Forty-three patients (34%) had locally advanced disease, and 84 patients (66%) had distant metastases; 94 patients (74%) received cytotoxic treatment during the course of their disease, and 33 (26%) received best supportive care only. First-line treatment consisted of gemcitabine (1,000 mg/m2 on days 1, 8, and 15 of a 28-day cycle) in 81 patients (86%), 5-fluorouracil (5-FU) in 8 patients (9%), radiochemotherapy in 4 patients (4%), and radiation therapy only in 1 patient (1%). A total of 1,501 gemcitabine treatments were given during the study period. Toxicity was moderate. Four patients (3%) required hospitalization for treatment-related side effects, and 111 patients (88%) died during the observation period. Symptom control, as measured by reduction of pain medication, was seen in 25% of patients receiving gemcitabine, whereas no reduction in pain medication was seen in the best supportive care group. The median survival of patients receiving cytotoxic treatment (mainly gemcitabine) was 42 weeks, and the median survival of patients receiving best supportive care was 21 weeks. The overall survival rate at 6, 12, 24, and 36 months was 65%, 32%, 14%, and 7%, respectively. Based on these outcomes, it appears that patients with locally advanced and metastatic pancreatic cancer benefit from adequate palliative treatment, including cytotoxic chemotherapy with gemcitabine, and this can be accomplished on an outpatient basis.

Successful long-term treatment of systemic lupus erythematosus with rituximab maintenance therapy.

Systemic lupus erythematosus (SLE) is a chronic, inflammatory autoimmune disease that may involve multiple organ systems. Treatment consists of immunosuppression, cytotoxic treatment, plasmapheresis and immunoglobuline therapy. Treatment of patients refractory to standard treatment approaches is difficult and results are poor. We describe a 39-year old patient with SLE suffering from grand mal epilepsy due to cerebral vasculopathy with positive lupus anticoagulant, who was refractory to standard treatment modalities. The patient was treated with the anti-CD20 monoclonal antibody rituximab (375 mg/m2 x 4, repeated at weekly intervals). Rituximab applications were delivered in October 2000, March 2001 and October 2001. Since March 2002 she has received maintenance therapy with rituximab 375 mg/m2 every three months. A second female with refractory SLE was treated successfully in April 2002 and receives maintenance therapy every three months. Both patients responded well to rituximab therapy. The first patient showed a major improvement of her clinical condition, and 30 months after the beginning of the rituximab therapy she is free of any symptoms. Inflammation parameters, ANA and lupus anticoagulant declined significantly after the treatment. The clinical condition of the second patient improved dramatically, all inflammation parameters normalized and her circulating immunocomplexes disappeared. In conclusion, rituximab maintenance treatment may be a new effective therapy in SLE.

[Severe lead poisoning due to Ayurvedic indian plant medicine]. / Chronische Bleivergiftung durch ayurvedische Heilpillen.

HISTORY AND CLINICAL FINDINGS: A 39-year-old woman with a history of slowly progressive muscular dystrophia was transferred to us for further evaluations of a hypochromic, microcytic anaemia. The patient complained about progressive muscle weakness, loss of appetite and constipation, sleep disorders as well as muscle and back pain. Clinical examination revealed a tetraparesis without any detectable muscle reflexes and atrophic muscles of the extremities. A bilateral radial paresis was found with a loss of power. INVESTIGATIONS: She presented with a hypochromic, microcytic anaemia with a haemoglobin of 7.9 g/dl. Re-evaluation of her peripheral blood smear showed basophilic stippling of the erythrocytes. Bone marrow biopsy revealed a marked dyserythropoiesis with 50% ring sideroblasts. After the examination of the bone marrow, the blood lead level was found to be grossly elevated up to 880 microg/l. DIAGNOSIS: Re-evaluation of the patient's history revealed that she had been to India for an Ayurvedic treatment approach to improve her muscle dystrophia. She had taken regularly 4 different natural plant pills which she had bought in an Ayurvedic health centre. Toxicologic analysis of these pills revealed one to have a lead concentration of 50.4 mg/g. TREATMENT AND COURSE: The patient was treated with 16 infusions of sodium-EDTA followed by a 4-week treatment with dimercaptopropionic acid orally. Her neurological condition improved and the radial paresis resolved gradually so that she could return to work. Her haematological parameters normalized. CONCLUSION: This case report underscores the importance, while asking patients for their drug history, to ask additionally if natural plant medicine is taken or applied regularly. The report reveals that Ayurvedic pills from India may have a high concentration of lead and may cause severe poisoning.

Dose reduction of steroid premedication for paclitaxel: no increase of hypersensitivity reactions.

BACKGROUND: Premedication with dexamethasone, ranitidine and clemastine is mandatory for patients receiving paclitaxel to avoid hypersensitivity reactions. The proposed dexamethasone dose is 20 mg orally 12 and 6 h prior to paclitaxel infusion. With this premedication severe hypersensitivity reactions are reduced to 1-2% of the treated patients. Besides this oral schedule a single dose of dexamethasone, 40 mg given i.v., just prior to paclitaxel has been shown to be equally effective. In an attempt to reduce steroid-induced side effects, especially for patients receiving weekly paclitaxel protocols, we reduced the dexamethasone dose. PATIENTS AND METHODS: A total of 132 patients were treated on an outpatient basis with paclitaxel-containing protocols. Paclitaxel was given in doses of 135-175 mg/m(2) once every 3 weeks in 76 patients and/or with 100 mg/m(2) weekly in 70 patients. Dexamethasone premedication was given in a single dose (40, 20, 10 mg) as an infusion directly before paclitaxel. RESULTS: 0/46 patients receiving 40 mg dexamethasone premedication in 235 cycles and 0/48 patients receiving 20 mg dexamethasone premedication in 186 cycles experienced a severe hypersensitivity reaction. 1/52 patients receiving 10 mg dexamethasone in 480 applications developed a severe hypersensitivity reaction with bronchospasm, hypotension and supraventricular tachycardia shortly after her first paclitaxel infusion started. CONCLUSION: No increase of severe hypersensitivity reactions is seen when dexamethasone premedication is reduced to doses of 20 or even 10 mg prior to paclitaxel infusion.

The polyneuropathy associated with Waldenström's macroglobulinaemia can be treated effectively with chemotherapy and the anti-CD20 monoclonal antibody rituximab.

A 50-year-old male developed headache, impaired balance, visual defects and severe deafness. Ten months later he presented with markedly reduced power and tremor of his right arm. Waldenström's macroglobulinaemia (WM) with accompanying polyneuropathy was diagnosed. The patient received chemotherapy, which resulted in a partial improvement of the arm tremor. Subsequently, he was treated with rituximab (4 x 375 mg/m2), leading to complete resolution of the tremor and the paresis of his arm. Additionally, his headache and imbalance disappeared. Fifteen months after rituximab therapy he remained free of any neurological symptoms. This is the first report showing that WM-associated polyneuropathy can be treated effectively with a combination of chemotherapy and the anti-CD20 monoclonal antibody rituximab.

Induction of complete haematological remission after monotherapy with anti-CD20 monoclonal antibody (RITUXIMAB) in a patient with alkylating agent resistant Waldenström's macroglobulinaemia.

Response of Waldenström's macroglobulinaemia to chemotherapy with alkylating agents is usually only transient. We report a case with marked bone marrow involvement and resistance to chemotherapy with alkylating agents. The patient was red cell and platelet transfusion dependent. Three weeks after rituximab-monotherapy, he achieved a complete haematological remission which is continuing 6 months after the end of therapy. Our case demonstrates that treatment with the unconjugated anti-CD20-monoclonal antibody (rituximab) may be a new powerful tool for a better treatment of Waldenström's macroglobulinaemia.

Immediate and long-term results of ATG induction therapy for delayed graft function compared to conventional therapy for immediate graft function.

The use of polyclonal antibodies for delayed graft function (DGF) was tested in 83 renal allograft recipients. Conventional immunosuppression (CI) was given to 52 patients with immediate graft function (IGF) while 31 patients with DGF received the polyclonal antibody ATG. Administration of OKT3 was restricted to steroid-resistant acute rejections in both groups. The incidence and severity of acute rejections, graft survival rate, CMV infections, and lymphocyte subsets were examined. ATG patients experienced a total of 0.6 acute rejections per patient, whereas CI patients had 0.9 on the average (P < 0.05). Second and third acute rejections occurred less frequently and later in the ATG group than in the CI group (P < 0.01). Steroid-resistant acute rejections occurred in 20 of the CI patients (38 %) but in only 7 of ATG patients (23 %). One-year graft survival in the CI and ATG groups was 98.1% and 93.2%, respectively. A decreased CD4 + to CD8 + T-lymphocyte ratio of about 0.5 was still detectable 5 years after the initial ATG administration. Hence, patients with DGF appear to benefit from induction therapy with ATG.

Persistent long-term changes in lymphocyte subsets induced by polyclonal antibodies.

BACKGROUND: Clinicians are well aware of the short-term effects of immunosuppression by mono- or polyclonal antibodies. Little is known about long-term changes induced by these therapies. METHODS: Forty-three renal allograft recipients were selected according to their initial postoperative immunosuppression: (1) BI group=basic immunosuppression with steroids and cyclosporine, n=16; (2) ATG group=basic immunosuppression plus polyclonal antibody antithymocyte globulin (ATG), n=11; and (3) OKT3 group=basic immunosuppression plus monoclonal antibody OKT3, n=16 patients. At intervals of 6 months, the following parameters were measured prospectively: lymphocyte surface antigens (HLA-DR, CD3, CD4, CD8, CD16, CD19, CD56, and CD57); serum and urine neopterin; serum amyloid A; and indirect and direct tests for herpes viruses. RESULTS: The mean period of observation was 58.4 months. The most significant differences between the groups occurred for CD4+ and CD8+ T cells. The ratios of CD4+ to CD8+ cells (n=278 measurements) were significantly and persistently lower in the ATG group (P<0.001, Brown-Mood test). Five years after transplantation, the ATG group had a CD4+ to CD8+ cell ratio of x=0.6 versus x=1.7 in the OKT3 group and x=2.0 in the BI group. This inversion was due to a persistent depletion of the CD4+ cells and an increased regeneration of the CD8+ cells, in particular of the CD8+brightCD57+ subpopulation. Extent and duration of CD4+ depletion correlated with the cumulative ATG dose (r=0.7, P<0.05, Spearman rank correlation test). CONCLUSION: Therapy with polyclonal antibody ATG induces dose-dependent long-term changes in T-cell lymphocyte subsets, which persist over a period of years.

Soluble intercellular adhesion molecule-1 in patients with lung cancer and benign lung diseases.

Intercellular adhesion molecule-1 (ICAM-1) expression correlates with tumour progression in patients with malignant melanoma or renal cell carcinoma. To assess the value of soluble ICAM-1 (sICAM-1) for lung cancer patients, sICAM-1 was determined by means of an enzyme-linked immunosorbent assay. Sera from 147 patients with lung cancer, from 75 patients with benign lung diseases and from 108 healthy adults were investigated for sICAM-1 expression. Significant differences in sICAM-1 levels were detected in lung cancer patients (387 +/- 176 ng/ml) and patients with benign lung diseases (365 +/- 110 ng/ml) compared to the group of healthy adults (310 +/- 90 ng/ml). There was no difference in sICAM-1 level among the subtypes of lung cancer. Advanced tumour stages and patients with progressive disease tended to be associated with higher sICAM-1 levels, the site of metastasis being relevant for the level attained. Patients with liver metastasis had the highest sICAM-1 levels (547 +/- 295 ng/ml) compared to patients with cerebral metastasis (317.8 +/- 92.2 ng/ml). An increase of sICAM-1 expression during the progression of the disease coincided with a poorer survival prognosis for the patients compared to patients with stable or falling sICAM-1 levels.

Storage of noncryopreserved periphered blood stem cells for transplantation.

Mobilized peripheral blood stem cells (PBSC) were collected in autologous plasma and acid-citrate-dextrose formula A (ACD-A) by leukaphereses using the CS3000 cell separator (Baxter) and stored at 4 degrees C in a refrigerator for 8 days. We have looked at the viability of the nucleated cells with the trypan blue test and the proliferation and differentiation capacity using a standardized progenitor cell cloning assay. The changes in viability, granulocyte-macrophage colony-forming units (CFU-GM), erythroid burst-forming units (BFU-E), and mixed-lineage colony-forming units (CFU-GEMM) were determined daily during the storage period. Viability was 90.8% (SD 8%) at day 0 and declined to a mean of 69.5% (SD 15.5%) at day 8. CFU-GM decreased to 47% (SD 28.7%), CFU-GEMM to 48% (SD 42.2%), and BFU-E to 40.1% (SD 18.4%) after 6 days. After 5 days of storage the mean viability was 79.7% (SD 17.8%), whereas the mean CFU-GM were 65.3% (SD 28.4%) the mean CFU-GEMM were 61.8% (SD 30.4%) and the mean BFU-E were 55.1% (SD 18.2%). At day 4 viability was still 82.5% (SD 17.0%), recovery of CFU-GM was 78.5% (SD 28.8%), recovery of CFU-GEMM was 70.7% (SD 40.4%) and recovery of BFU-E was 65.0% (SD 17.5%). These data show, that PBSC can be stored safely over at least 5 days at 4 degrees C while the patient receives high-dose chemotherapy.

Successful treatment of neutropenia in T-LGL leukemia (T gamma-lymphocytosis) with granulocyte colony-stimulating factor.

Severe neutropenia is a common feature in patients with T-large granular lymphocytic (LGL) leukemia. Neutropenia often causes severe infections and septicemia, thus representing a major cause of morbidity and mortality in this disease. We have treated two outpatients with T-LGL leukemia who had severe neutropenia (neutrophils < 0.2 x 10(9)/l) successfully with G-CSF (5 micrograms/kg daily, s.c.). After 10 days of treatment the neutrophil count was within the normal range and a severe oral infection healed rapidly. We conclude that G-CSF therapy is able to normalize the neutrophil count in T-LGL leukemia within a few days and that it can be used to treat severe infections in these patients even on an outpatient basis.

Anemia with LDH-elevation in a patient with aortic valve replacement.

In a 63-year old patient with a history of aortic valve replacement in 1986, a reduced hemoglobin of 91 g/l was found by a family physician. Since serum LDH was also increased, the patient was diagnosed to suffer from mechanically induced, hemolytic anemia and presented at our hospital for further diagnosis and evaluation of the aortic valve prosthesis.

Peri-operative changes of cellular and humoral components of immunity with brain tumour surgery.

Nosocomial infections, which are not uncommon in neurosurgical intensive care medicine, may possibly be favoured by an impairment of immunological competence of the patient. In a prospective observational trial, we investigated several parameters of cellular and humoral immunity in 32 patients before and after resection of an intracranial tumour. We quantified the effects of operative procedure, dexamethasone pretreatment, and tumour type. Dexamethasone alone causes an increase of neutrophilic granulocyte count and monocytes, whereas IgG and eosinophilic granulocytes decrease as well as lymphocytes. CD4+ T lymphocytes (T helper cells) and CD8+ T lymphocytes (T cytotoxic/suppressor cells) were more severely affected than B lymphocytes. Dexamethasone and operation in combination act synergistically on T lymphocytes and IgG, while no synergism is obvious in other clinical test parameters. The skin sensitivity reaction was depressed accordingly. With intracerebral tumours (gliomas WHO grades II to IV), levels of T helper cells and eosinophilic granulocytes were lower, and levels of IgM and neutrophilic granulocytes were higher than with benign extracerebral neoplasms. Postoperative nosocomial infections of the lower respiratory tract occurred almost exclusively in patients subject to severe depression of T helper cells.

Immobilization and light-dark cycle-induced modulation of serotonin metabolism in rat brain and of lymphocyte subpopulations: in vivo voltammetric and FACS analyses.

The effect of immobilization and light-dark cycle on the serotoninergic system of the n. raphe dorsalis and on the distribution of blood lymphocyte subpopulations was studied in the rat. As was shown by in vivo voltammetry, 10 min immobilization enhanced serotonin metabolism with a maximum 15 min after immobilization. The distribution of the blood lymphocytes into subpopulations was also affected: pan-T and T helper lymphocytes were reduced during immobilization and reached minimum values after 20 min recovery. The circadian rhythms of serotonin metabolism and the distribution of pan-T and T helper cells exhibited a slight phase shift if compared with each other.
