Induction or consolidation systemic therapy in the multimodality treatment of unresectable locally advanced non-small cell lung cancer.
Chemoradiotherapy has been shown to improve survival over radiation alone for unresectable locally advanced non-small cell lung cancer (NSCLC). Large randomized trials comparing sequential to concomitant platinum based chemoradiotherapy have demonstrated improved median survival times in favor of concomitant treatment. Recent phase II trials have evaluated the integration of advanced radiotherapy techniques, novel chemotherapy combinations, induction chemotherapy, and consolidation chemotherapy with concomitant chemoradiotherapy. On-going or recently completed phase III trials are evaluating whether the promising regimens from phase II studies are superior to concomitant chemoradiotherapy alone. Molecular therapies now need to be integrated with chemoradiotherapy.

Multimodality nuclear medicine imaging in three-dimensional radiation treatment planning for lung cancer: challenges and prospects.
The purpose of this study was to determine the utility of quantitative single photon emission computed tomography (SPECT) lung perfusion scans and F-18 fluorodeoxyglucose positron emission computed tomography (PET) during X-ray computed tomography (CT)-based treatment planning for patients with lung cancer. Pre-radiotherapy SPECT (n = 104) and PET (n = 35) images were available to the clinician to assist in radiation field design for patients with bronchogenic cancer. The SPECT and PET scans were registered with anatomic information derived from CT. The information from SPECT and PET provides the treatment planner with functional data not seen with CT. SPECT yields three-dimensional (3D) lung perfusion maps. PET provides 3D metabolic images that assist in tumor localization. The impact of the nuclear medicine images on the treatment planning process was assessed by determining the frequency, type, and extent of changes to plans. Pre-radiotherapy SPECT scans were used to modify 11 (11%) treatment plans; primarily altering beam angles to avoid highly functioning tissue. Fifty (48%) SPECT datasets were judged to be 'potentially useful' due to the detection of hypoperfused regions of the lungs, but were not used during treatment planning. PET data influenced 34% (12 of 35) of the treatment plans examined, and resulted in enlarging portions of the beam aperture (margins) up to 15 mm. Challenges associated with image quality and registration arise when utilizing nuclear medicine data in the treatment planning process. Initial implementation of advanced SPECT image reconstruction techniques that are not typically used in the clinic suggests that the reconstruction method may influence dose response data derived from the SPECT images and improve image registration with CT. The use of nuclear medicine transmission computed tomography (TCT) for both SPECT and PET is presented as a possible tool to reconstruct more accurate emission images and to aid in the registration of emission data with the planning CT. Nuclear medicine imaging techniques appear to be a potentially valuable tool during radiotherapy treatment planning for patients with lung cancer. The utilization of accurate nuclear medicine image reconstruction techniques and TCT may improve the treatment planning process.

Multimodal management of diffuse neonatal hemangiomatosis.
Diffuse neonatal hemangiomatosis is a rare, frequently fatal disorder. We describe the case of a neonate with numerous cutaneous and ocular hemangiomas. Hepatic hemangiomas were noted at 4 weeks of age, associated with congestive heart failure resulting from hepatic arteriovenous shunting. This condition was controlled by treatment with prednisone, interferon alfa-2b and hepatic embolization. Treatment of cutaneous hemangiomas with the tunable dye laser prevented hemorrhage, facilitated routine skin care, and allowed uninhibited intravenous access during hospitalization.

Multimodality therapy for head and neck cancer.
The refinement of radiation therapy techniques should result in a decrease in morbidity in canine and feline nasal carcinoma patients and should further allow for the addition of adjuvant therapies. Patients with large oral tumors that are incompletely excised should have radiation therapy added to their treatment regimen. Tumors with significant metastatic potential, such as melanoma, should be considered for addition of chemotherapy. Carboplatin has activity in melanomas and is being added at several institutions, but trial results are not yet available. Chemoradiation has become the treatment of choice for human head and neck squamous cell carcinomas but remains largely unexplored in veterinary medicine. Hopefully, development of chemoradiation will benefit feline squamous cell carcinoma patients, because current treatment regimens are largely ineffective. Immunotherapy agents and targeted biologic therapeutics seem to hold promise for the future.

Multimodality therapy: using the best available treatments together rationally.
Cancer cases comprise an increasingly important part of companion animal practice. As the state of veterinary oncology continues to improve, the combined use of modalities (surgery, chemotherapy, and radiotherapy for the most part, biologic response modification to some extent) will be widely evaluated, and its clinical application will become more common.

Multimodal cancer chemotherapy during the first and second trimester of pregnancy: a case report.
This paper reports treatment with combined chemotherapy during pregnancy. A 39-year-old woman with breast cancer was given adjuvant chemotherapy including cyclophosphamide, methotrexate and 6-fluorouracil from the 6th to the 24th week of gestation. The possibility of teratogenic effects on the fetus was explained to the patient however she refused to terminate the pregnancy. A 30-week male infant with only a minor malformation was delivered. The authors reviewed the literature regarding chemotherapeutic agents given during the first trimester of pregnancy. Most cytotoxic drugs have teratogenic effects on experimental animal subjects. However, actual data on human fetuses are sparse because of the variety of therapeutic regimens and the rarity of administering chemotherapy during pregnancy. The long-term effects of exposure to cytotoxic drugs in utero, needs further research.

Multimodal ultrasound assessment of cerebral hemodynamics in a patient with a diffuse cerebral angiomatosis.
Recent newly developed ultrasound (US) techniques extend our ability to study the cerebral hemodynamics in patients with arteriovenous malformations (AVM) beyond the conventional cerebral blood flow velocity (CBFV) analysis. We present US data of global cerebral blood flow (CBF) and global cerebral circulation time (CCT) in a patient with a unique bihemispherial diffuse cerebral angiomatosis and compare them with 10 age-matched controls. In addition, the estimation of an US-derived global cerebral blood volume (CBV) is proposed. Duplex sonographic CBF analysis revealed 2620 mL/min in the patient and 754 +/- 93 mL/min in controls. Doppler sonographic CCT was 2.9 s and 6.3 +/- 1.5 s and CBV 126 mL and 79 +/- 19 mL, respectively. US allows a simple, minimal invasive bedside analysis of several global hemodynamic parameters that might provide valuable additional information in patients with diffusely altered cerebral hemodynamics.

Multimodal functional imaging of prolonged neurological deficits in a patient suffering from familial hemiplegic migraine.
The case of a patient with familial hemiplegic migraine (FHM) suffering from prolonged right sided hemiparesis and aphasia that persisted for more than 10 days is reported. The symptoms were accompanied by slowing of the magnetoencephalogram over the left hemisphere, which normalized parallel to the clinical improvement. Positron emission tomography obtained on the 6th day revealed glucose-hypometabolism (hemispheric difference > or =10%) in left hemisphere's fronto-basal cortex, caudate nucleus, and thalamus. In contrast, magnetic resonance imaging including perfusion and diffusion weighted imaging was normal and did not show significant alterations of cortical perfusion or water mobility during the episode. We hypothesize that this finding provides evidence for a primary neuronal dysfunction causing the prolonged neurological deficits in FHM.

Human hypnosis: autonomic and electroencephalographic correlates of a guided multimodal cognitive-emotional imagery.
The effects of a guided neutral and unpleasant imagery involving several sensory modalities were studied in hypnotized subjects. Heart rate (HR), respiratory frequency (RF), tonic skin resistance and different electroencephalographic rhythms were evaluated during a long-lasting hypnotic session including the guided suggestion of a neutral (NS) and an unpleasant (US) imagery, each preceded by a hypnotic relaxation rest period. During NS, the absence of autonomic changes, associated with electroencephalographic gamma power decrement and theta1 power increment, indicated the prevalence of relaxation on the expected task-related modifications. In contrast, US elicited HR and RF increments together with higher electroencephalographic gamma, beta3 and beta2 activities. Thus, hypnotic state appears to prevent the autonomic responses expected during the neutral stimulation, while the emotional valence of the unpleasant imagery overwhelms the hypnosis-related relaxation.

Effectiveness of a multimodal treatment program for chronic low-back pain.
In recent years, multidisciplinary pain programs were seen to successfully treat patients by basing treatment on a combination of physical exercise and psychological interventions. However, in spite of their effectiveness, it still remains to be clarified exactly which features of these programs were responsible for patient improvement. Cognitive-behavioral models posit that improvement is due, in part, to changes in patient coping strategies. Nonetheless, as reflected by the conflicting opinions present in the literature, it is questionable whether a so-called 'cognitive shift' is an accurate indicator for return to work of disabled patients. Ninety patients with chronic low back pain took part in a multidisciplinary treatment program. Therapeutic environment reinforces wellness behavior and enhances the patients' sense of control over their pain and resulting disability. The main therapeutic target point was to facilitate return to work. Ways of coping were measured by a well studied coping inventory in the German language (FEKB). Factor analysis revealed three factors: 'catastrophizing', 'search for information' and 'cognitive control'. In addition, assessment included measurements of pain intensity, depression, disability, flexibility of the lumbar spine, and different performance parameters. All of them were measured prior to and at the end of treatment, and following intervals of 6 and 12 months after discharge from program. Measurements showed significant changes over time, but more importantly, nearly all results were seen to stabilize at the 6- and 12-month evaluation following treatment. The coping strategies demonstrated little or poor change. In addition, coping measures and change in coping behavior showed poor prognostic relevance. But other psycho-social parameters like self-evaluation of potential return-to-work, application for pension, the length of pre-absence from work, and a decrease in subjective disability following treatment were effective indicators for 'back-to-work'. Other objective parameters, such as medical history, physical impairment and general physical variables were seen to have little predictive value in determining a return to work. The results suggest that the primary target point for further investigation is the analysis of the patients' beliefs about their pain. Our results indicate that future research must be attentive to the complex interactions between environmental factors and the coping demands posed by the specific nature of pain problems.

Multimodal assessment of the effect of chewing gum on nicotine withdrawal.
The present study was designed to evaluate the usefulness of chewing gum to reduce nicotine withdrawal, craving, and salivary cortisol concentrations during temporary nicotine deprivation. A total of 20 male smokers were studied under conditions when gum was and was not accessible during a 4-hour deprivation period. All subjects smoked an initial cigarette shortly after arrival for the two experimental sessions and were informed that they would be unable to smoke for the remainder of each session. The sessions consisted of each subject watching a movie, then waiting in the lab for two consecutive 30-min intervals. Self-reported nicotine withdrawal and craving were assessed four times and salivary cortisol five times during each experimental session. Results from this study indicate that chewing gum helps with self-reported withdrawal but not craving when a smoker is prevented from smoking. This study also provides preliminary data on the use of salivary cortisol as a physiological marker that may map these self-reports of nicotine withdrawal and craving.

What is the role of radiation in the treatment of subfoveal membranes: review of radiobiologic, pathologic, and other considerations to initiate a multimodality discussion.
BACKGROUND: Single-dose-fraction conformal proton beam and multiple-fraction X ray dose schedules have been used to treat subfoveal neovascular membranes. All schedules successfully controlled membrane progression, stabilized vision in most patients, and increased visual acuity in some. Conformal protons also decreased the radiation dose to healthy tissues outside the designated volume (16 mm in diameter). It appears that radiation therapy could be useful and cost-effective, but neither the optimal time-dose schedule single or multiple dose fractions nor the type of radiation proton conformal beam or x-ray therapy are defined. METHODS: By means of an extensive literature survey, we reviewed the rationale for using radiation to treat subfoveal neovascularization, examined a paradigm of radiation interaction with tissue, reviewed the histopathology of neovascular membranes, and documented the role of growth factors in the pathophysiology of the disease. Accepting that the eye is an extracranial brain extension, and that its microvasculature has properties similar to brain microvessels, we reviewed the radiobiologic response of brain microvessels. We also revisited the controversy concerning the efficacy of single-dose-fraction vs. multifraction schedules. RESULTS: This paper outlines parameters within which radiation therapy's role might be defined, and proposes a clinical radiation-biology scoring program to evaluate radiation effects, based on the SOMA concept. CONCLUSION: A prospective, controlled clinical trial is feasible and is indicated to determine radiation therapy's role in managing the proliferative component of age-related macular degeneration.

Radiotherapy and multimodality management of cholangiocarcinoma.
PURPOSE: To evaluate the results of radiotherapy in cholangiocarcinoma patients managed with various combinations of chemotherapy and surgical resection with selective liver transplantation. METHODS AND MATERIALS: From January 1990 to December 1995, 61 patients with histologically confirmed biliary duct adenocarcinoma were seen in the Radiation Oncology Department of the University of Pittsburgh. Median follow-up was 22 months (1 to 91 months). The extent of surgery was complete resection in 23 patients (including 17 with orthotopic liver transplant), partial resection in 4, and biopsy in 34. All patients had radiotherapy; median dose was 49.5 Gy. Thirty patients received chemotherapy: 5-fluorouracil (5-FU)-leucovorin with interferon alpha (IFNalpha) in 27, and taxol in 3. RESULTS: The median survival was 20 months (95% CI 15-25 months). The 5-year actuarial survival was 23.8 +/- 6.8%. The only significant variable in multivariate analysis was achieving a complete resection with negative margins through conventional surgery or liver transplantation (p = 0.001, hazard rate ratio [HRR] = 0.25, 95% CI 0.12-0.54). Patients with complete resections had a 5-year actuarial survival of 53.5 +/- 10.9%. CONCLUSION: Combined modality therapy that includes complete surgical resection with or without transplantation can be curative in the majority of patients with biliary duct carcinoma. Further study is needed to better define the roles of chemotherapy and radiotherapy in cholangiocarcinoma.

Local control with multimodality therapy for stage 4 neuroblastoma.
PURPOSE: To evaluate the efficacy of 21 Gy hyperfractionated radiotherapy for local control in conjunction with surgery and intensive systemic therapy for patients with Stage 4 neuroblastoma. METHODS AND MATERIALS: After achieving a partial or complete remission, 47 children, ages 1-10 years, with Stage 4 neuroblastoma were treated on four consecutive institutional protocols (N4-N7) with dose-intensive multi-agent chemotherapy, maximal surgical debulking, and hyperfractionated radiotherapy (1.5 Gy twice a day to 21 Gy). Radiotherapy fields encompassed the initial tumor volume and regional lymph nodes plus a 3-cm margin. This was followed by consolidation with either autologous bone marrow transplantation (N4 and N5) or immunotherapy (N6 and N7). RESULTS: Forty-five of 47 patients had a complete response to surgery and chemotherapy prior to radiotherapy. Five-year actuarial rates of local control, progression-free survival, and overall survival were 84%, 40%, and 45%, respectively. Among 26 patients who relapsed, 1 failed only at the primary site, 22 developed distant metastases exclusively, and 3 had both local and distant failures. There were no acute complications of radiotherapy. CONCLUSION: Hyperfractionated radiotherapy to 21 Gy, in conjunction with dose-intensive systemic therapy and aggressive surgical resection, is well tolerated and is associated with durable local control for most patients with Stage 4 neuroblastoma.
