Nasal saline irrigation could also be considered as a safe alternative in breast-feeding women. Elderly  ar in elderly patients is treated generally as it is in younger adults. Therefore, first-line agents are primarily incss and second-generation oral or possibly intranasal antihistamines. 5,7,25 older patients may also have a component of atrophy of nasal tissues that can result in more nasal congestion. Most will benefit from regular nasal saline irrigation. 5 the elderly are more sensitive to the sedative and antimuscarinic effects of (especially first-generation) antihistamines and to the cardiovascular and cns-stimulant effects of decongestants. These drugs should be used cautiously if at all. An increase in cholinergic activity may result in more rhinorrhea. This may respond well to ipratropium. »» ocular symptoms5,27,41,42 several products are available for instillation directly into the eyes for those patients with predominant or unresponsive ocular manifestations. They may be appropriate for occasional moderate–severe flares or episodic ar when other modes of therapy are not optimally effective. The combination (antihistamine and mast cell stabilizing) agents may be the most effective, and they have the advantages of rapid onset of action and (usually) only twice daily administration. Ketotifen is in this category and because it is available otc, it can be an appropriate initial agent. See table 63–8 for these products. Summary of treatment once an agent appropriate for initial therapy is chosen, ongoing management requires repeated checks to ascertain response and freedom from intolerable or adherence limiting side effects. Either “step-up” or “step-down” therapy may be appropriate, depending on individual response. See table 63–9 for a summary of the approach to treatment of ar.

rock essay A pivotal study showed that pci reduces the incidence of brain metastasis and increases the 3-year survival rate from 15% to 21%. 14 patients with limited stage sclc who achieve a complete response with treatment should be offered pci. »» extensive disease platinum regimens, particularly ep, are the treatment of choice in extensive disease. In one japanese study, a combination of irinotecan and cisplatin demonstrated an increased median survival time by approximately 3 months over the ep regimen. This irinotecan–cisplatin regimen also had a lower incidence of severe neutropenic side effects but exhibited higher rates of middle- to high-grade diarrhea. However, this study was repeated in the united states and did not show a similar improvement over the ep regimen. 15 therefore, ep remains the regimen of choice for treating extensive sclc in the united states. Because of the high sensitivity of treatment-naïve sclc to chemotherapy, it is imperative that these patients be monitored for signs of tumor lysis syndrome and possibly treated with prophylactic therapy. »» recurrent disease treatment of non–small cell lung cancer the first step in treatment of nsclc involves confirmation of the clinical stage and determination of likelihood of resection of the tumor. When the histology results are not of squamous cell histology (adenocarcinoma and large cell), tissue should be sent for genetic analysis of egfr mutations and alk rearrangement. Treatment options depend on the stage of disease (ie, eligibility for resection), ps, histology, and genetic findings. »» local disease (stages 1a, 1b, and iia) local disease encompasses stages ia through iia and is associated with a favorable prognosis because approximately 40% to 60% of patients are expected to live more than 5 years from diagnosis. Goals of therapy are curative in local disease, and surgery is the mainstay of treatment regardless of histology or genetics. Stage ia tumors are rarely seen clinically and may be treated with surgery alone. If surgical margins are positive, radiotherapy or re-resection is recommended. 17 stage ib, iia, and locally advanced iib nsclc are treated with adjuvant chemotherapy. The rationale behind adjuvant chemotherapy is to eradicate micrometastases or other tumor cells that may have been missed during removal of the primary tumor. The recent results of five relatively large prospective trials suggest that there is benefit chapter 90  |  lung cancer  1341 advanced non–small cell lung cancer non–squamous cell histology—send for genetic analysis to identify egfr+ or alk+ tumors for squamous histology (25% of lung cancers) consider sending for genetic analysis if never smoker or mixed histology egfr+ (15% of adenocarcinomas) alk+ (3%–7% of non–small cell lung cancers) egfr and alk wt or unknown erlotinib or afatinib treat to progression crizotinib treat to progression platinum doublet with or without bevacizumaba treat for 4–8 cycles afatinib treat to progression ceritinib treat to progression maintenance therapy with pemetrexeda or erlotinib treat to progression second-line therapy with nivolumab or pembrolizumabb or gemcitabine or pemetrexeda or docetaxel treat to progression consider additional therapy for responding patients or best supportive care a b pemetrexed and bevacizumab are not indicated for squamous histology pembrolizumab is only indicated for patients with tumors expressing pd-l1 figure 90–2.
