It is usually well tolerated gastritis reviews buy 200mcg misoprostol amex, and brain necrosis that occurred in less than 10% of cases is usually limited and had no clinical consequences. The patient outcome depends mostly on the progression rate of extra cerebral lesions (1015). Data on lung and liver metastases are available only in retrospective studies on low numbers of patients and with a median follow-up of less than 1 year in most cases and in one prospective study (1016). This study included patients with many different primary tumors, including 10% of the patients having thyroid cancer. They showed a local control rate ranging from 63% to 98% in lung lesions, from 57% to 100% in liver lesions with a cumulative dose delivered ranging from 20-75 Gy in 5-15 fractions. The local tumor control seems to be long lasting with complete response ranging form 70 to 90 % at 2-3 years. Furthermore, rare (<3%) grade 3-4 toxicities (pneumonitis, pleural effusion, intestinal complications) were reported (1017). These toxicities are much less common that those associated with percutaneous treatment modalities. Percutaneous thermal ablation is aimed to destroy tumor foci by increasing (radiofrequency ablation) or decreasing (cryoablation) temperatures sufficiently to induce irreversible cellular damages. A multicenter prospective trial on 183 lung metastases from cancer other than colorectal showed a complete response rate of 88 % at 1 year and an overall survival of 92% and 64% at 1 year and at 2 years, respectively (1022). Cases of delayed recurrence have also been reported, and long-term follow up is needed. Furthermore, repeated treatments can be performed on the same lesion and multiple lesions can be treated in the same patient. The association of cryoablation and cementoplasty seems promising in purely lytic bone metastases from thyroid cancer. Published experience using thermal ablation and stereotactic radiation in thyroid cancer patients is limited, and recommendations are currently based on more robust evidence in other solid tumors. Randomized prospective studies comparing the efficacy and tolerability of these different techniques are lacking, and their choice in clinical practice is based on local experience, lesion location as well as patient status and preference. Surgical resection and stereotactic external beam radiotherapy are the mainstays of therapy (933;1029;1030). Stereotactic radiation therapy is preferred to whole brain irradiation because life expectancy in patients with brain metastases may be prolonged, and stereotactic irradiation induces less short and long-term toxic damages to the brain toxicity compared with whole brain irradiation (fatigue, headache, cognitive decline, and behavioral changes), and it may be effective even in patients with multiple brain lesions. Clinicians considering referral of patients for trials should review available treatment options and eligibility criteria, preferably through discussions with trial center personnel and review of trial materials at the website 246 Page 247 of 411 247 The reasons for this association are unclear, but there is no evidence to suggest that trial participation is deleterious to patient outcomes, and it may be beneficial. Participation in a clinical trial should be considered in any situation wherein there exists no effective or proven standard of care, or when a standard of care is being compared with a promising new or investigational therapy. However, given the indolent nature of metastatic disease in most patients, therapeutic clinical trial participation should not be considered for patients with stable, asymptomatic metastatic disease unless agents with significant likelihood of complete remission, prolongation of survival, or biologic impact such as redifferentiation that could sensitize to definitive therapy are available (see section [C37]). Benefit has been demonstrated in the form of improved progression free survival (delay in time to disease progression or death) in three randomized, double-blinded, placebo-controlled, clinical trials (vandetanib (1033); sorafenib (1013); lenvatinib (1034). Benefit has also been demonstrated in the form of induced durable tumor regression (1035-1037). In the absence of definitive data related to improved overall survival and/or quality of life to inform As a guide, evidence-based recommendations with expert consensus have been recently published (953). It is also critically important to assure that the disease prompting therapy represents metastatic thyroid cancer. In particular, because pulmonary nodules attributable to benign causes are common, the presence of pulmonary nodules does not in and of itself justify the application of systemic therapy. Thus, in cases of diagnostic uncertainty where the result would have definitive therapeutic implications, biopsy is required, especially when thyroglobulin levels are low/unhelpful (such as in the presence of anti-thyroglobulin antibodies). The introduction of systemic therapy requires that both the clinician and the patient agree that clinical benefits are expected to exceed risks for that individual patient. Finally, it is important that the involved care team (physicians, physician assistants, nurse practitioners, nurses) be experienced in the use and management of toxicities associated with these therapies. Appropriate informed consent should be obtained and documented in the medical record prior to initiation of any therapy, regardless of whether the patient is being treated in the context of a clinical trial. Kinase inhibitors, however, are associated with numerous adverse effects including diarrhea, fatigue, induced hypertension (requiring initiation of antihypertensive therapy in about half of all 251 Page 252 of 411 252 previously normotensive individuals), hepatotoxicity, skin changes, nausea, increased levothyroxine dosage requirement, changes in taste and weight loss. These potential side effects have high probability of negatively impacting quality of life and/or necessitating dosage reductions in nearly two-thirds of treated many patients, and treatment discontinuation in up to 20% of patients. Overall, the risk of therapy-related death in cancer patients treated with oral kinase inhibitors is about 1. While risk of drug-related death is relatively low, this knowledge of potentially fatal therapeutic outcomes should prompt considerable restraint in the use of kinase inhibitors in patients with stable or slowly progressive disease who likely have a disease-specific mortality that may also be low over 1-3 years. While risk of drug-related death is relatively low, the knowledge of potentially fatal therapeutic outcomes should prompt considerable restraint in the use of kinase inhibitors, especially in patients who are asymptomatic and/or with stable or slowly progressive disease, and in patients who can otherwise be effectively treated using directed therapies. Three randomized placebo-controlled clinical trials (phase 2, vandetanib; phase 3, sorafenib and lenvatinib) had been published by the time of the writing of these guidelines, each demonstrating delayed time to disease progression among kinase inhibitor-treated, relative to 252 Page 253 of 411 253 placebo-treated, patients (1013;1033;1034). Sorafenib or vandetanib treatement were each associated with progression free survival prolonged by 5 months, with <15% objective response rates, but with no improvement on overall survival demonstrated to date. Assessments comparing sorafenib to placebo outcomes demonstrated overall lower quality of life among sorafenib-treated patients relative to those treated with placebo, despite improved progression free survival. Lenvatinib therapy was associated with longer prolonged median progression free survival by 14. Despite these very encouraging results and regulatory approval, however, no statistically significant impact of lenvatinib (or any other kinase inhibitor) therapy on overall survival has yet been observed; moreover, lenvatinib toxicities were reported in 100% of treated patients (1034). None of the yet-completed randomized trials have demonstrated survival benefit for kinase inhibitor therapy relative to placebo, perhaps in part reflecting crossover from placebo to kinase inhibitor therapy among progressing placebo-treated trial patients, raising the question of whether delay of therapy initiation adversely affected patient outcomes among enrolled trial patients. In some situations, however, the decision to initiate kinase inhibitor therapy is straightforward. For patients with disease between these two extremes, it is critical that risks and benefits of therapy, anticipated side effects, goals, patient context, and the therapeutic 254 Page 255 of 411 255 philosophy of each particular patient be thoroughly vetted so as to best individualize therapy. This decision is ideally made within the context of specialized centers with comprehensive knowledge of the natural history of the disease and of the effects of available therapies. Specific characteristics impacting enthusiasm for starting such therapy are outlined in Table 16. Patients who are candidates for kinase inhibitor therapy should be thoroughly counseled with regard not only to potential benefits, but also with regard to potential side effects and risks of therapy, as well as with regard to alternative therapeutic approaches including best supportive care, as should be the case with any medical therapeutic decision-making (1044). Such extensive and comprehensive discussions are particularly important to undertake in the context of kinase inhibitor therapy because of the high probability of side effects of these agents and because of their presently uncertain effects on patient overall survival and quality of life (1045). Another critical and complex question often faced in treating patients with kinase inhibitor therapy is that of when treatment should be discontinued once initiated. In general, therapy should be continued so long as net benefit exceeds net detriment. However, there are times when focal/oligometastatic disease progression 255 Page 256 of 411 256 amenable to directed therapies is noted. In such instances, superimposed loco-regional therapies in the setting of maintained systemic therapy can sometimes be in the best interest of a particular patient. For instance, in the setting of regressed lung metastases and yet progression at a solitary bone site, maintained systemic therapy with superimposed directed radiation therapy may be reasonable. Ideally, such therapy should be undertaken within the context of therapeutic clinical trials. Hence, the selection of an agent for initial therapy may be in some senses less critical, as many patient will go on to receive several kinase inhibitors over their disease courses. Cardiotoxicity is also important to be aware of and to monitor according to patient risk factors, agent used, and induced symptoms/signs.

Examine the feet of all patients with diabetes annually for the presence of peripheral artery disease, even in the absence of foot ulceration. At a minimum, this should include taking a relevant history and palpating foot pulses. Clinically examine (by relevant history and palpation of foot pulses) all patients with diabetes and foot ulceration for the presence of peripheral artery disease. Always consider vascular imaging in patients with a diabetic foot ulcer, irrespective of the results of bedside tests, when the ulcer is not healing within 4-6 weeks despite good standard of care. Always consider revascularisation in a patient with a diabetic foot ulcer and peripheral artery disease, irrespective of the results of bedside tests, when the ulcer is not healing within 4-6 weeks despite optimal management. Do not assume diabetic microangiopathy, when present, is the cause of poor healing in patients with a diabetic foot ulcer, therefore always consider other possibilities for poor healing. Evaluate the entire lower extremity arterial circulation with detailed visualisation of below-theknee and pedal arteries, in an anteroposterior and lateral plane. When performing revascularisation in a patient with a diabetic foot ulcer, aim to restore direct blood flow to at least one of the foot arteries, preferably the artery that supplies the anatomical region of the ulcer. After the procedure, evaluate its effectiveness with an objective measurement of perfusion. As evidence is inadequate to establish whether an endovascular, open or hybrid revascularisation technique is superior, make decisions based on individual factors, such as morphological distribution of peripheral artery disease, availability of autogenous vein, patient co-morbidities and local expertise. Ensure that after a revascularisation procedure in a patient with a diabetic foot ulcer, the patient is treated by a multidisciplinary team as part of a comprehensive care plan.
