Stage III Stage III is the most complex of the NSCLC stages. There are significant differences in the treatment of stage IIIA versus IIIB disease. Stage IIIA disease includes a tumor that has invaded the chest wall, diaphragm, or the pleura of the mediastinum or heart, and has ipsilateral hilar or mediastinal lymph node involvement T3N1M0 or T3N2M0 ; . The term ipsilateral refers to structures on the same side of the chest as the primary tumor see Figure 4 ; . Smaller tumors that involve the ipsilateral mediastinal lymph nodes are also stage IIIA T1N2M0 or T2N2M0 ; . Stage IIIA is potentially operable disease. Preoperative treatment is used for some people and is currently under evaluation in clinical trials. Stage IIIB disease includes any size tumor that has invaded any of the vital structures of the mediastinum, the carina, or a bone of the spine T4 tumors ; , with or without regional lymph node involvement T4N0M0, T4N1M0, T4N3M0 ; . Smaller tumors T1-3 ; associated with contralateral lymph node involvement or supraclavicular lymph node involvement are also stage IIIB. The term contralateral refers to structures on the opposite side of the chest as the primary tumor. A separate tumor nodule in the same lobe of the lung as the primary tumor.
How do you file your appeal of the initial decision? Either you, someone you appoint, or your provider, with your written consent, may file this appeal. If you are appointing someone to represent you, you must state so in writing or complete an Appointment of Representation form, which is available upon request from Member Services. You may submit your appeal orally or in writing. If you file orally, you must also submit a written, signed appeal request; unless you are filing a Fast Appeal. How soon must you file your appeal? You must submit your appeal within 30 days of the date of our notification to you. If we have not sent a written notice to you, you may appeal within 365 days of the action. How can my benefits be continued while my appeal is being considered? In order for this to occur: 1. You must file your appeal within 10 days of the date of the notice of action if filing orally, or within 15 days if filing in writing and submitting via US mail, or prior to the intended effective date of our proposed action; 2. The appeal must involve the termination, suspension, or reduction of a previously authorized course of treatment; 3. The services must have been ordered by an authorized provider; 4. The authorization period cannot have expired; and 5. You request an extension of benefits. If you request this and your appeal is not decided in your favor, you may be liable for all costs accrued during the review process. What if you want a "fast" appeal? You, any doctor, or your authorized representative can ask us to give a "fast" appeal rather than a "standard" appeal ; about medical care by calling us at Member Services, 1-800-278-8178, Monday through Friday, 8 a.m. to 5 p.m. Or, you can deliver a written report to HealthEase Healthy Kids, P.O. Box 25765, Tampa, FL 33622-5765 or fax it to 813-262-2857. Be sure to ask for a "fast" or "expedited" review. If any doctors ask for a fast appeal for you, or support you in asking for one, and the doctor indicates that waiting for a standard decision could seriously harm your health or your ability to function, we will automatically give you a fast appeal. If you ask for a fast appeal without support from a doctor, we will decide if your health requires a fast decision. If we decide that your medical condition does not meet the requirements for a fast appeal, we will send you a letter informing you that if you get a doctor's support for a fast review, we will automatically give you a fast decision. The letter will also tell you how to file a "grievance" if you disagree with our decision to deny your request for a fast review. If we deny your request for a fast appeal, we will instead give you a standard appeal typically within 30 calendar days ; . How soon must we decide on your appeal? 1. For a decision about payment for care you already received. After we receive your appeal, we have 45 calendar days to make a decision. We will notify you of this extension in writing and give you grievance rights if you do not agree with the extension. 2. For a standard decision about your medical care. After we receive your appeal, we have up to 30 calendar days to make a decision, but will make it sooner if your health condition requires. However, if you request it, or if we find that some information is missing which can help you, we can take up to 14 more calendar days to make our decision. We will notify you of this extension in writing and give you grievance rights if you do not agree with the extension. 3. For a fast decision about medical care. After we receive your appeal, we have up to 72 hours to make a decision, but will make it sooner if your health requires.

6.4.4 Recommendations Somatostatin analogues are the primary treatment for carcinoid tumours associated with production of peptides. For patients with insulinoma and gastrinoma, they may be second- or third-line agents. may be considered for asymptomatic patients with progressive disease. should be used to prevent or treat carcinoid crises before, during, and after procedures such as surgery and embolization. Standard dosages of somatostatin analogues are octreotide: short-acting form, 100500 g three times daily; long-acting form, 1030 mg up to 60 mg ; every 4 weeks; and lanreotide: slow release form, 60120 mg every 4 weeks. Interferon alfa alone or in combination with somatostatin analogues ; is a primary medical treatment for low-proliferating gastroenteropancreatic tumours. may be a second-line therapy after cytotoxic treatment. should be titrated individually in each patient. Aim for reduction of leukocyte count to about 3.0109 L. The usual dosage of regular interferon alfa is 35 million units subcutaneously, 3 5 times weekly. The dose of pegylated interferon alfa is not yet established, but may be 75150 g subcutaneously per week. Cytotoxic treatment may be a first-line treatment for malignant neuroendocrine tumours in the pancreas and for gastric carcinoids if Ki67 antibody level is greater than 10%. may be a second-line treatment if other means of treatment fail, and after tumour-targeted radioactive treatment. agents are used at these dosages: 5-day induction with streptozotocin 1 g daily intravenously for 5 days, plus 5-FU 400 mg m2 on days 1 3. Thereafter, streptozotocin 2 g and 5-FU 400 mg m2 intravenously during 1 day every 3 weeks until toxicity develops. If doxorubicin is combined with streptozotocin, 40 mg m2 is given on day 3. One or two years after stabilization, the interval between courses may be increased to 46 weeks consensus category 2B and dronabinol.

20 The second stage was performing the Marshall sample for both mix designs of SMA14 and AC14. The method of dry process was used in preparing the rubber modified asphalt mixes. 136 Marshall samples were prepared including both modified and unmodified samples. For the purpose of incorporating CRM into modified mixes, the detail procedures recommended by past researchers and Arkansas State Highway and Transportation Department were adopted according to the literature review. The bulk specific gravity and density of compacted sample were done in accordance to ASTM 2726. The stability and flow test were conducted for compacted sample according to ASTM D 1559. An average value of theoretical maximum density was obtained through the test as described in ASTM D 2041 on two samples using rice method for each different mixes. Wheel tracking test was carried out with three samples for both mix designs in measuring rutting after obtaining the optimum bitumen and crumb rubber content that most improve the HMA properties and dss.
Carboplatin etoposide, cyclophosphamide doxorubicin achieved good response rates. Improving long-term survival, however, has remained problematic. Treat ment with biological response modifiers interferons alpha and gamma ; has not shown promise in this setting. New agents showing good preliminary singleagent activity in untreated SCLC include paclitaxel, vinorelbine, gemcitabine, topotecan, and teniposide. Results obtained with single-agent docetaxel and CPT-11 are thus far inconclusive. Studies evaluating in.

Fractory setting indicated an overall response rate of 68%, including patients with at least a minor response.25 Encouragingly, responses were seen even at dose levels well below what would be considered standard for single-agent bortezomib and melphalan, and patients with prior exposure to this alkylating agent responded as well. Thalidomide with bortezomib, without or with the addition of dexamethasone, is also an active regimen, having an overall response rate of 52%, with 17% CRs or near-CRs.26 Again, responses were seen in patients who had previously progressed on thalidomide-based therapy, though these patients had an inferior survival compared with those who had not received prior thalidomide. Bortezomib with thalidomide and dexamethasone is another very active regimen in the initial therapy of multiple myeloma, 27 associated with an overall response rate of 80%, and 94% in those patients who received bortezomib at higher levels than the commonly used 1.3 mg m2. Combination regimens based on bortezomib and doxorubicin have also been encouraging. A phase I trial in patients with advanced hematologic malignancies found that bortezomib with pegylated liposomal doxorubicin Doxil ; was tolerable.28 Some increase in grade 1-2 toxicity was observed with the combination, but the incidence of most grade 3-4 toxicities was similar to the historical experience with single agent bortezomib. An overall response rate of 73% in patients with relapsed refractory multiple myeloma was noted, with a CR + near-CR rate of 36%. Interestingly, in a subset of patients previously treated with doxorubicin-based therapies who were either frankly refractory, or had only brief responses, the CR and overall response rate was comparable to that in patients who had initially responded well to doxorubicin. These results led to an ongoing international phase III trial comparing single-agent bortezomib with the combination of bortezomib and pegylated liposomal doxorubicin in relapsed refractory myeloma. This regimen is also being evaluated by the Cancer and Leukemia Group B as an induction therapy for patients with previously untreated, symptomatic multiple myeloma.29 Interim results from the latter trial show an overall response rate of 80%, with no patients suffering progressive disease.

As a new or continuing member in our plan, you may be taking drugs that are not on our formulary. Or, you may be taking a drug that is on our formulary, but your ability to get it is limited. For example, you may need a prior authorization from us before you can fill your prescription. You should talk to your doctor to decide if you should switch to an appropriate drug that we cover or request a formulary exception so that we will cover the drug you take. While you talk to your doctor to determine the right course of action for you, we may cover your drug in certain cases during the first 90 days you are a member of our plan. For each of your drugs that is not on our formulary, or if your ability to get your drugs is limited, we will cover a temporary 30-day supply unless you have a prescription written for fewer days ; when you go to a network pharmacy. After your first 30-day supply, we will not pay for these drugs, even if you have been a member of the plan less than 90 days. If you are a resident of a long-term care facility, we will cover a temporary 31-day transition supply unless you have a prescription written for fewer days ; . We will cover more than one refill of these drugs for the first 90 days you are a member of our plan. If you need a drug that is not on our formulary or if your ability to get your drugs is limited, but you are past the first 90 days of membership in our plan, we will cover a 31-day emergency supply of that drug unless you have a prescription for fewer days ; while you pursue a formulary exception. If you are a current member in our plan, we will also cover a temporary transition supply if you have a change in your medications because of level of care change.

Also will address a number of secondary aims, in particular, assessing novel methods to evaluate tumor response. The next high-risk study will build on the success of D9802, continuing the use of irinotecan vincristine. However, since patients treated in the IRS STS window trials had no better outcome than those treated in the IRS-III trial, and since no candidate novel agents are ready for phase II testing, we will exploit this as an opportunity to evaluate a different strategy in this patient group at high risk for treatment failure. Following initial exposure to irinotecan vincristine, the study will test whether dose-compressed treatment with alternating combinations of vincristine doxorubicin cyclophosphamide and ifosfamide etoposide among the most active combinations from prior window trials ; will improve outcome. The trial will also evaluate the safety of irinotecan radiosensitization in the context of this aggressive multiagent chemotherapy regimen. Most patients who develop tumor recurrence have a dismal prognosis [86]. The ongoing relapse study, ARST0121, is a randomized comparison of two different schedules of irinotecan administration both administered with vincristine ; . After the initial window evaluation, patients receive alternating vincristine doxorubicin cyclophosphamide VDC ; and ifosfamide etoposide cycles, administered in standard 3-week cycles. These combinations were selected because both have substantial activity in RMS and none of the active front-line studies use these combinations. Patients whose tumors fail to respond to irinotecan vincristine and those not receiving the window also receive tirapazamine Tirazone; Sanofi-Synthelabo Inc., New York, : sanofi-synthelabo ; [87, 88] with VDC cycles. As the new high-risk study is implemented, new strategies for patients relapsing after that trial will be needed. New treatment strategies are clearly needed, particularly for higher-risk, newly diagnosed patients and for those who develop recurrent tumors, where there has been little improvement in outcome. The promise of identification of new treatment targets through gene-expression analyses is looming, and efforts are underway to expand the availability of tumor tissue for these analyses. Such targeted therapy holds great promise for new treatments in RMS and other childhood solid tumors. The new National Cancer Institute Pediatric Preclinical Testing Program, led by Dr. Peter Houghton, promises to identify new agents. This is of particular importance for RMS, where single-institution and IRS COG studies have amply demonstrated the ability of such preclinical drug testing models to predict clinical activity [8993]. This and other ongoing efforts, including studies of CpG oligopeptides [94], oncolytic herpes simplex virus tumor injections [95, 96], rapamycin analogs [97], vaccines against small peptide fragments that span the PAX3-FKHR.
Daunorubicin and doxorubicin
A new liposomal version of doxorubicin called doxil has been recently approved as a kaposi's sarcoma treatment and echinacea.
For vitamin A and its provitamins, sum mation should be made in mg * g ; all-trans retinol equivalent. Provitamins, if their separate summation is required, should be expressed in mg * g ; Y-caroteneequiva lent. If possible, the number of carotenoid equivalents and preformed retinol equiva lents should be indicated as well as the equivalency ratio used. It is emphasized that discretion must be used in the accep tance of values from food tables and the interpretation of findings from biological tests. Thus, although all-trans retinol is to be used as the summation substance, it is greatly inferior, in view of its instability, to aH-frans-retinyl acetate 9-trans, ll-rans, 13--rans-retinyl ctate ; as the stan a dard for biological tests. For vitamin E, summations should be made in mg fig ; RRR-a-tocopherol equiv alent. Although RRR-a-tocopherol is to be used as the summation substance, it is greatly inferior, in view of its instability and variable biological activity to RRR-atocopheryl acetate as the standard for bio logical tests.
The Royal Marsden group.35 Among all their 451 patients receiving a single melphalan 200 mg m2-based transplant between 1985 and 2001, 8-year event-free survival EFS ; and overall survival OS ; rates were 16% and 34%, respectively.36 Similar results have been observed by the European Blood and Marrow Transplant Registry.37 In contrast to a single cycle of high-dose melphalan, repeated administrations of melphalan at low doses inflict only sublethal tumor cell damage and, therefore, may promote additional mutations, increasing genomic instability in tumor cells. Because of its hematopoietic stem cell toxicity, chronic application of low-dose melphalan also increases the risk of secondary myelodysplasia t-MDS ; .38 Indeed, the risk of t-MDS is much higher when patients have received prolonged standard therapy prior to autotransplants. In a retrospective analysis, all 7 cases of t-MDS were identified in a group of 117 patients with more extensive standard therapy prior to transplantation, whereas no such cases were observed in the 71 patients with minimal prior therapy.38 Moreover, using interphase fluorescence in situ hybridization FISH ; technology, the signature chromosomal abnormalities of MDS were already detectable in the collected stem cells, lending further support to the contribution of chronic low-dose alkylating agent therapy to the development of MDS after autotransplantation.39 PBSC procurement is compromised by prolonged exposure to stem celltoxic standard-dose alkylating agent regimens, including melphalan and nitrosoureas, and by local irradiation to bone marrowcontaining sites.40, 41 The nonmyelotoxic VAD regimen 4-day continuous infusion of vincristine and doxorubicin hydrochloride [Adriamycin; Pharmacia & Upjohn, Kalamazoo, MI] plus dexamethasone pulsing ; has emerged as the induction therapy of choice prior to hematopoietic stem cell procurement.42 Although assuring prompt hematopoietic recovery in the majority of patients receiving an adequate number of CD34 cells 2 106 kg, but preferably 5 106 kg ; , autografts do not protect against damage to other organ sites. Mucositis has emerged as the dose-limiting toxicity of most autotransplantation trials using melphalan. To achieve further tumor cytoreduction in more patients and beyond the clinical CR threshold corresponding to 109-1010 tumor cells ; , tandem autotransplantations were introduced as a means to increase CR rate and to extend the duration of disease control and survival. When spaced by 3 to months to allow for sufficient mucous membrane recovery, repeated applications of melphalan 200 mg m2 can be administered safely with a cumulative mortality rate of 2% to 3%. Thus, a phase 2 pilot trial of Total Therapy I effected stringently defined CR in 40% of patients.43 An update of an historically controlled comparison of 152 untreated patients receiving Total Therapy I and Southwest Oncology Group SWOG ; standard therapies S8624, S9028, S9210 ; revealed significant prolongation of both EFS and OS in the high-dose therapy group Figure 1, Table 1 ; . Patients were matched by age and prestudy levels of B2M and albumin and efalizumab.
