Phantom limb pain has been treated with multiple modalities with di ering levels o success. What is relatively clear is that i phantom limb pain persists beyond 6 months, the likelihood o improvement in the long term is decreased signi cantly.40 pharmacologic therapies or phantom limb pain have generally shown overall poor success at treatment.40 with this noted there is anecdotal success with some agents including opioids, membrane stabilizers (gabapentin, pregabalin), benzodiazepines, nmda antagonists, and calcitonin. A recent cochrane review indicates that there is not enough su cient support to recommend the routine use o any speci c pharmacologic agent in the treatment o phantom limb pain.41 interventional and other nonpharmacologic options seem to have better results than medication-based approaches overall. Some o the modalities that have had more success in treatment include thermal bio eedback, motor cortex stimulation, deep brain stimulation, and dorsal root entry zone (drez) lesioning (figure 6-7). Psychological options, including bio eedback, cognitive behavioral therapy, support groups, and hypnosis, have all been employed with some e cacy.42 71 ch r onic pa in in neur ologica l pat ient s ▲ f g e 6-7 motor cortex stimulation.

The recognition of graft-versus-tumor effect, which likely is caused by cytotoxic t lymphocytes in the donor stem cells in those undergoing a allogeneic hsct transplant, led to investigations with nonmyeloablative transplants, in which less toxic preparative regimens are used in the hope of expanding the availability of hsct to recipients whose medical condition or age prohibits use of myeloablative regimens. A myeloablative or nonmyeloablative preparative regimen may be used for allogeneic hsct. Only myeloablative preparative regimens are used for autologous hsct. Histocompatibility histocompatibility differences between the donor and the recipient necessitate immunosuppression after an allogeneic hsct because considerable morbidity and mortality are associated with graft failure and gvhd. Rejection is least likely to occur with a syngeneic donor. In patients without a syngeneic donor, initial hla typing is conducted on family members because the likelihood of complete histocompatibility between unrelated individuals is remote.

Repeated doses are typically not recommended because mannitol may diffuse into brain tissue, leading to rebound increased icp. 31 around 20% patients with brain metastases may present with seizures and require anticonvulsant therapy. Phenytoin is the most frequently used agent with a loading dose of 15 mg/kg followed by 300 mg by mouth daily (titrated to therapeutic levels between 10 and 20 mcg/ml [40 and 79 μmol/l]). Diazepam 5 mg iv may be used for rapid control of persistent seizures. Prophylactic anticonvulsants have frequently been used. However, a systematic review did not support their use. 32 thus, because adverse effects and drug interactions are common, the routine use of prophylactic anticonvulsants is not recommended. Outcome evaluation the success of therapy is based on the ability to decrease symptoms, treat the underlying sites of disease within the brain, and prolong survival. Urologic complications. Hemorrhagic cystitis introduction hemorrhagic cystitis is defined as acute or insidious bleeding from the lining of the bladder. Although therapy with certain medications is the most common cause, it is also the most preventable. Once it occurs, hemorrhagic cystitis causes significant morbidity and mortality rates between 2% and 4%. This section focuses on preventive strategies for chemotherapeutic causes of hemorrhagic cystitis. Epidemiology and etiology numerous etiologies have been linked to hemorrhagic cystitis (table 99–11). 34 of these, the oxazaphosphorine alkylating agents (cyclophosphamide and ifosfamide) are most 1478  section 16  |  oncologic disorders table 99–11  primary causes of hemorrhagic cystitis pharmacologic nonpharmacologic cyclophosphamide chronic low doses high-doses used in bmt ifosfamide intravesicular thiotepa chronic oral busulfan anabolic steroids pelvic irradiation viral infection cmv papovavirus herpes simplex virus adenovirus bmt, bone marrow transplantation. Cmv, cytomegalovirus. From west nj. Prevention and treatment of hemorrhagic cystitis. Pharmacotherapy. 1997;17:696–706. Frequently implicated. Hemorrhagic cystitis is the dose-limiting toxicity of ifosfamide and predisposes patients with bladder cancer. Incidence rates vary considerably but generally range between 18% and 40% with ifosfamide and 0. 5% to 40% with high-dose (300 mg/m2 or more) cyclophosphamide in the absence of prophylactic measures. 35 chronic, low-dose oral cyclophosphamide as typically used in autoimmune disorders and chronic lymphocytic leukemia is infrequently associated with hemorrhagic cystitis. Around 20% patients receiving pelvic irradiation may experience hemorrhagic cystitis, especially with concurrent cyclophosphamide. Viral infections commonly associated with this condition most frequently occur in bone marrow transplant recipients who may also receive cyclophosphamide. Pathophysiology cyclophosphamide- or ifosfamide-induced damage to the bladder wall is primarily caused by their shared metabolite known as acrolein. Acrolein causes sloughing and inflammation of the bladder lining, leading to bleeding and hemorrhage. This is most common when urine output is low because higher concentrations of acrolein come into contact with the bladder urothelium for longer periods of time.

Prevention the use of effective prevention strategies can decrease the incidence of hemorrhagic cystitis to fewer than 5% in patients receiving cyclophosphamide or ifosfamide. Three methods are used to reduce the risk. Administration of mesna (2-mercaptoethane sulfonate), hyperhydration, and bladder irrigation with catheterization. Mesna is the primary method used with ifosfamide.
