Johnson1 1Cancer Research UK Centre, University of Southampton, Southampton, United Kingdom Although radiotherapy is highly effective for the treatment of Hodgkin lymphoma, the realization of its potential long-term toxicity and the demonstration of excellent results from combination chemotherapy have led to a retreat from its use in early-stage disease. Recent trials using functional imaging may allow better identiﬁcation of those patients for whom radiotherapy may be safely omitted without compromising cure rates and this review examines the evidence for this. Introduction ischaemia at lower radiation doses; a recent analysis suggested an More than a century has passed since it was ﬁrst shown that overall hazard ratio (HR) of more than 12 for those treated with Hodgkin lymphoma could be effectively treated by irradiation1 and mediastinal radiotherapy in childhood. Nonetheless, it is also clear from The evidence of second malignancies related to radiation exposure many trials that the results of treatment for early-stage disease are continues to accumulate. The clearest risks are for epithelial cancers improved by the combination of chemotherapy with radiation. The within or adjacent to the radiotherapy ﬁeld, which show a latency principle of combination treatment has led to the greatest advances of 3 years but increase progressively over time. To what of this are complicated by the extensive use of alkylating agents at extent is this retreat from radiation justiﬁed by the evidence from the same time, which carry a signiﬁcant risk in their own right. This review examines the results of previous trials risks of secondary solid tumors are clearest for breast cancer in and the emerging data from several recent studies that have sought women given extensive radiotherapy to the thorax including the to use functional imaging to guide a more selective approach using axillae. The relative risks are highest for those irradiated around the measurements of the response to chemotherapy to determine age of puberty and decrease progressively with older age at whether to use radiotherapy. The time body, on the premise that Hodgkin lymphoma progresses in an taken to develop breast cancer seems to be slightly shorter for those anatomically coherent fashion from node to node and that seem- irradiated younger, the relative risk peaking at 10 to 14 years for ingly uninvolved nodes may harbor subclinical deposits that can be those irradiated before the age of 20 and 15 to 19 years for those eliminated by irradiation. In a large study from the United Kingdom, irradiation (STNI) including the cervical, axillary, mediastinal, the total cumulative risk reached nearly 50% for those treated under hilar, and paraaortic nodes and the spleen treated in sequence. The dominant problems that emerge are cardiovascular disease and hypothyroidism and thyroid cancers is also substantial after cervical secondary malignancies.

This is an important rather than the whole node group. The deﬁnition of the precise ﬁeld point, because when the question becomes the complete omission for this involved-node irradiation remains a matter of some debate, of radiotherapy, the intensity of the chemotherapy is likely to in particular the margins required to allow for movement during become an even more dominant consideration, at least in the treatment and whether functional imaging using 2-(18F)ﬂuoro-2- initial control of the disease.

The relative risks of death from Hodgkin lymphoma or from the complications of treatment are a key Reducing the dose of radiation and the interaction consideration in selecting a regimen, with much current research with chemotherapy aimed at determining where the balance lies and how both might be In addition to reducing the size of radiotherapy ﬁelds, several minimized simultaneously. Historically, doses of 36 Gy and higher were used for the consolidation of remission in early-stage disease,18-20 but modern Omitting radiotherapy altogether practice is to apply 30 Gy or less in some circumstances.

Case-control studies are preferred only when the outcome measure is rare and the study is well conducted discount elavil 25 mg online joint & pain treatment center. Systematic reviews pay particular attention to whether results of efficacy studies can be generalized to broader applications buy elavil 10mg otc unifour pain treatment center nc. Efficacy studies provide the best information about how a drug performs in a controlled setting. These studies attempt to tightly control potential confounding factors and bias; however, for this reason the results of efficacy studies may not be applicable to many, and sometimes to most, patients seen in everyday practice. Most efficacy studies use strict eligibility criteria that may exclude patients based on their age, sex, adherence to treatment, or severity of illness. In addition, efficacy studies frequently exclude patients who have comorbid disease, meaning disease other than the one under study. Efficacy studies may also use dosing regimens and follow-up protocols that are impractical in typical practice settings. These studies often restrict options that are of value in actual practice, such as combination therapies and switching to other drugs. Efficacy studies also often examine the short-term effects of drugs that in practice are used for much longer periods. Finally, efficacy studies tend to assess effects by using objective measures that do not capture all of the benefits and harms of a drug or do not reflect the outcomes that are most important to patients and their families. Systematic reviews highlight studies that reflect actual clinical effectiveness in unselected patients and community practice settings. Effectiveness studies conducted in primary care or office-based settings use less stringent eligibility criteria, more often assess health outcomes, and have longer follow-up periods than most efficacy studies. The results of effectiveness studies are more applicable to the “average” patient than results from the highly selected populations in efficacy studies. Examples of effectiveness outcomes include quality of life, frequency or duration of hospitalizations, social function, and the ability to work. These outcomes are more important to patients, family, and care providers than surrogate or intermediate measures. For example, a study might use very narrow inclusion criteria like an efficacy study, but, like an effectiveness study, might examine flexible dosing regimens, have a long follow-up period, and measure quality of life and functional outcomes. For this report we sought evidence about outcomes that are important to patients and would normally be considered appropriate for an effectiveness study. However, many of the studies that reported these outcomes were short-term and used strict inclusion criteria to select eligible patients. For these reasons, it was neither possible nor desirable to exclude evidence based on these characteristics. Labeling a study as either an efficacy or an effectiveness study, although convenient, is of limited value; it is more useful to consider whether the patient population, interventions, time frame, and outcomes are relevant to one’s practice or to a particular patient. Studies anywhere on the continuum from efficacy to effectiveness can be useful in comparing the clinical value of different drugs. Effectiveness studies are more applicable to practice, but efficacy studies are a useful scientific standard for determining whether characteristics of different drugs are related to their effects on disease. Systematic reviews thoroughly cover the efficacy data in order to ensure that decision makers can assess the scope, quality, and relevance of the available data. This thoroughness is not intended to obscure the fact that efficacy data, no matter how large the quantity, may have limited applicability to practice. Clinicians can judge the relevance of study results to their practice and should note where there are gaps in the available scientific information. Unfortunately, for many drugs there exist few or no effectiveness studies and many efficacy studies. Yet clinicians must decide on treatment for patients who would not have been included in controlled trials and for whom the effectiveness and tolerability of the different drugs are uncertain. Systematic reviews indicate whether or not there exists evidence that drugs differ in their effects in various subgroups of patients, but they do not attempt to set a standard for how results of controlled trials should be applied to patients who would not have been eligible for them. With or without an evidence report, these decisions must be informed by clinical judgment. In the context of development of recommendations for clinical practice, systematic reviews are useful because they define the strengths and limits of the evidence, clarifying whether assertions about the value of an intervention are based on strong evidence from clinical studies. Judgment, reasoning, and applying one’s values under conditions of uncertainty must also play a role in decision making.
