Psoriasis is a common, chronic, inflammatory, multisystem disease with predominantly skin and joint manifestations affecting approximately 2% of the population. In this second of 5 sections of the guidelines of care for psoriasis, we give an overview of psoriatic arthritis including its cardinal clinical features, pathogenesis, prognosis, classification, assessment tools used to evaluate psoriatic arthritis, and the approach to treatment. Although patients with mild to moderate psoriatic arthritis may be treated with nonsteroidal anti-inflammatory drugs and/or intra-articular steroid injections, the use of disease-modifying antirheumatic drugs, particularly methotrexate, along with the biologic agents, are considered the standard of care in patients with more significant psoriatic arthritis. We will discuss the use of disease-modifying antirheumatic drugs and the biologic therapies in the treatment of patients with moderate to severe psoriatic arthritis.

When cancer is diagnosed in a pregnant woman, life-saving chemotherapy for the mother poses life-threatening concerns for the developing fetus. Depending on the type of cancer and the stage at diagnosis, chemotherapy cannot necessarily be delayed until after delivery. Women diagnosed with acute lymphoblastic leukaemia who decline both termination and chemotherapy often die with the previable fetus in utero. Safe use of chemotherapy, especially during the second and third trimester, have been reported, and pregnant women with cancer can accept therapy without definite neonatal harm. Here, we review the use of chemotherapy in pregnancy by trimester of exposure and summarise neonatal outcomes, including malformations, perinatal complications, and oldest age of neonatal follow-up. We will also discuss the modes of action of the drugs used and look at the multiagent regimens recommended for use during pregnancy.

Use of chemotherapy during human pregnancy

Background: We conducted a systematic review and meta-analysis to clarify the risk of early and late cardiotoxicity of anthracycline agents in patients treated for breast or ovarian cancer, lymphoma, myeloma or sarcoma. Methods: Randomized controlled trials were sought using comprehensive searches of electronic databases in June 2008. Reference lists of retrieved articles were also scanned for additional articles. Outcomes investigated were early or late clinical and sub-clinical cardiotoxicity. Trial quality was assessed, and data were pooled through meta-analysis where appropriate. Results: Fifty-five published RCTs were included; the majority were on women with advanced breast cancer. A significantly greater risk of clinical cardiotoxicity was found with anthracycline compared with non-anthracycline regimens (OR 5.43 95% confidence interval: 2.34, 12.62), anthracycline versus mitoxantrone (OR 2.88 95% confidence interval: 1.29, 6.44), and bolus versus continuous anthracycline infusions (OR 4.13 95% confidence interval: 1.75, 9.72). Risk of clinical cardiotoxicity was significantly lower with epirubicin versus doxorubicin (OR 0.39 95% confidence interval: 0.20, 0.78), liposomal versus non-liposomal doxorubicin (OR 0.18 95% confidence interval: 0.08, 0.38) and with a concomitant cardioprotective agent (OR 0.21 95% confidence interval: 0.13, 0.33). No statistical heterogeneity was found for these pooled analyses. A similar pattern of results were found for subclinical cardiotoxicity; with risk significantly greater with anthracycline containing regimens and bolus administration; and significantly lower risk with epirubicin, liposomal doxorubicin versus doxorubicin but not epirubicin, and with concomitant use of a cardioprotective agent. Low to moderate statistical heterogeneity was found for two of the five pooled analyses, perhaps due to the different criteria used for reduction in Left Ventricular Ejection Fraction. Meta-analyses of any cardiotoxicity (clinical and subclinical) showed moderate to high statistical heterogeneity for four of five pooled analyses; criteria for any cardiotoxic event differed between studies. Nonetheless the pattern of results was similar to those for clinical or subclinical cardiotoxicity described above.

Cardiotoxicity of anthracycline agents for the treatment of cancer: systematic review and meta-analysis of randomised controlled trials

For the past 40 years, various forms of interferon (IFN) have been evaluated as therapy in a number of malignant and non-malignant diseases. With the advent of gene cloning, large quantities of pure IFN became available for clinical study. This paper reviews the biology, pharmacology, and clinical applications of IFN formulations most commonly used in oncology. It then reviews the most common side effects seen in patients treated with IFN, and makes recommendations for the management of IFN-induced toxicity. The major oncological indications for IFN include melanoma, renal cell carcinoma, AIDS-related Kaposi’s sarcoma, follicular lymphoma, hairy cell leukemia, and chronic myelogenous leukemia. Unfortunately, IFN therapy is associated with significant toxicity, which can be divided into constitutional, neuropsychiatric, hematologic, and hepatic effects. These toxicities have a major impact on the patient’s quality of life, and on the physician’s ability to optimally treat the patient. Careful attention to all aspects of patient care can result in improved tolerability of this difficult but promising therapy. Conclusion: a better understanding of IFN biology, indications, side effect profiles, and toxicity management will aid in optimizing its use in the treatment of patients with cancer.

Psoriasis is a common, chronic, inflammatory, multisystem disease with predominantly skin and joint manifestations affecting approximately 2% of the population. In this fourth of 6 sections of the guidelines of care for psoriasis, we discuss the use of traditional systemic medications for the treatment of patients with psoriasis. Treatment should be tailored to meet individual patients' needs. We will discuss in detail the efficacy and safety, and offer recommendations for the use of the 3 most commonly used, and approved, traditional systemic agents: methotrexate, cyclosporine, and acitretin. We will also briefly discuss the available data for the use of azathioprine, fumaric acid esters, hydroxyurea, leflunomide, mycophenolate mofetil, sulfasalazine, tacrolimus, and 6-thioguanine in psoriasis.

To evaluate the potential teratogenicity of modern cancer treatment, 43 children born to mothers with hematological malignancies (18 with non-Hodgkin lymphoma, 14 Hodgkin disease, seven acute leukemia, and four with chronic granulocytic leukemia) who received chemotherapy during some portion of their pregnancy, including 19 of these 43 who received chemotherapy during the first trimester, were examined for physical health, growth, and development. Immunological, hematological, and cytogenetic status also were evaluated. The children's ages ranged from 3 to 19 years. The children had a careful history and physical examination to detect any abnormal symptoms or signs and the mother's previous chemotherapy was carefully documented. In all of the children studied, physical, neurological, psychological, hematological, immune function, and cytogenetics were normal. These results suggest that chemotherapy can be administered during pregnancy, even during the first trimester, because it is not hazardous to the fetus; nevertheless, this study is inadequate in size to exclude the possibility of teratogenesis, and more reports are necessary to define the best treatment from cancer during pregnancy.

Treatment of stage IA non-Hodgkin's lymphoma (NHL) of Waldeyer's ring remains controversial, probably because of the small number of patients and the scarcity of controlled studies. Between 1981 and 1991, 316 patients with stage I NHL of Waldeyer's ring were randomised for treatment with radiotherapy alone (extended fields), 101 patients; combined chemotherapy with a regimen of CHOP (cyclophosphamide, vincristine, doxorubicin, and prednisone) or CHOP-like (epirubicin instead of doxorubicin), 106 patients; and combined therapy (radiotherapy followed by the same combination chemotherapy), 109 patients. Median follow-up was 6.8 years. Complete response was achieved in 93, 87 and 97%, respectively. Relapses were least frequent in patients treated with combination therapy. The 5-year rate for failure-free survival was 48% for radiation therapy, 45% for the patients who were treated with chemotherapy, which was statistically significantly less than the 83% for patients treated with combined therapy (P < 0.001). Overall survival was also better in the combined therapy arm: 90%, statistically different to 58% for the patients treated with chemotherapy alone and 56% for patients treated with radiation therapy (P < 0.001). Toxicity was mild and late side-effects were not observed in any patients. From these results combined therapy should be considered as the best therapeutic approach in patients with localised NHL of Waldeyer's ring.

We assessed the efficacy and toxicity of interferon alpha 2b (IFN) as maintenance therapy in patients with low grade malignant lymphoma Between March 1986 and December 1989, 98 patients with low-grade malignant lymphoma in complete remission after conventional chemotherapy were randomly assigned to received IFN, 50 MU three times a week for one year, as maintenance therapy (n = 48) or to receive no treatment (control group, n = 50)In March 1994, the median duration of response had not yet been reached in the patients treated with IFN compared to 46 months in the control group At 9-years 62% of the patients in the IFN arm remain in first complete remission compared to only 25% in the control group (p < 001) In addition, the median duration of survival has not yet been reached in either the IFN arm compared to 74 months in the control group (p < 001) Quality of life was excellent in both groups and severe side effects secondary to IFN treatment were not observed All patients completed the planned

A study was carried out to investigate the efficacy and toxicity of granulocyte colony-stimulating factor (G-CSF) in the treatment of infection in 119 severely granulocytopenic patients with hematological malignancies after intensive chemotherapy. Patients were assigned randomly to receive either antibiotics alone (ceftazidime, 2 g, i.v., every 8 h + amikacin 7.5 mg/kg, i.v., every 12 h) or the same antimicrobial regimen plus G-CSF (5 micrograms/kg/day, s.c.). Measurements were clinical improvement, eradication of infection and toxicity. Patients who received antibiotics plus G-CSF had more clinical responses (82 versus 60%), less superinfections (6 versus 20%), less mortality (5 versus 15 patients), less days in hospital (median 10 versus 27) and reduced antibiotic usage compared to patients who received only antibiotics. Hematological recovery (granulocytes > 1.0 x 10(9)/l) was also shorter in these patients (12 versus 23 days). Fungal infections occurred only in the group treated with antibiotics alone. Toxicity secondary to G-CSF was absent. We conclude that the addition of G-CSF to broad spectrum antibiotics is useful in selected patients with severe granulocyctopenia after intensive chemotherapy and infection, because if may prove the outcome in these patients.
