Lung Cancer

Only about 15% of patients diagnosed with lung carcinoma eachyear are surgical candidates, either due to advanced disease orcomorbidities. The past decade has seen the emergence of minimallyinvasive therapies using thermal energy sources: radiofrequency,cryoablation, focused ultrasound, laser, and microwave; radiofrequencyablation (RFA) is the best developed of these. Radiofrequency ablationis safe and technically highly successful in terms of initial ablation.Long-term local control or complete necrosis rates drop considerablywhen tumors are larger than 3 cm, although repeat ablations can beperformed. Patients with lung metastases tend to fare better with RFlung ablation than those with primary lung carcinoma in terms of localcontrol, but it is unclear if this is related to smaller tumor size at time oftreatment, lesion size uniformity, and sphericity with lung metastases,or to differences in patterns of pathologic spread of disease. The effectsof RFA on quality of life, particularly dyspnea and pain, as well aslong-term outcome studies are generally lacking. Even so, the resultsregarding RF lung ablation are comparable to other therapies currentlyavailable, particularly for the conventionally unresectable or high-risklung cancer population. With refinements in technology, patient selection,clinical applications, and methods of follow-up, RFA will continueto flourish as a potentially viable stand-alone or complementarytherapy for both primary and secondary lung malignancies in standardand high-risk populations.

Mesotheliomas are uncommon in the United States, with an incidenceof about 3,000 new cases per year (or a risk of about 11 per million Americansper year). Incidence and mortality, however, are probably underestimated.Most are associated with asbestos, although some have arisen inports of prior radiation, and a reported association with simian virus (SV)40remains controversial. About 85% of mesotheliomas arise in the pleura,about 9% in the peritoneum, and a small percentage in the pericardiumor tunica vaginalis testis. The histology of about half of mesotheliomas isepithelial (tubular papillary), with the remainder sarcomatous or mixed.Multicystic mesotheliomas and well-differentiated papillary mesotheliomasare associated with long survival in the absence of treatmentand should be excluded from clinical trials intended for the usual rapidlylethal histologic variants of the disease. The median survival isunder a year, although longer median survivals for selected patients,particularly those with epithelial histology, have been reported in somecombined-modality studies. Recent randomized trials have shown significantimprovement in time to progression and survival for the additionof new antifolates to platinum-based chemotherapy.

BARCELONA, Spain-Final results of a large international phase III trial confirm the benefit of adjuvant chemotherapy after complete resection in patients with early-stage non-small-cell lung cancer (NSCLC). Rafael Rosell, MD, of Catalan Institute of Oncology, Badalona, Spain, presented the results of the trial, known as ANITA (Adjuvant Navelbine International Trialist Association), at a plenary session of the 11th World Conference on Lung Cancer. Earlier this year, Jean-Yves Douillard, MD, PhD, head, Division of Medical Oncology, Rene Gauducheau Cancer Center, Saint-Herblain, France, reported the study findings at the American Society of Clinical Oncology 41st Annual Meeting .

ORLANDO - A 2-minute breath test to detect volatile organic compounds (VOCs) successfully predicted lung cancer in patients with stage I-IV disease, according to a study reported by Michael Phillips, MD, at the American Society of Clinical Oncology 41st Annual Meeting (abstract 9510). "The breath test may potentially become a useful adjunct to lung cancer detection," said Dr. Phillips, clinical professor of medicine, New York Medical College, Valhalla.

We applaud Dr. Cappuzzo andcolleagues for an excellentreview of an emerging fieldin lung cancer treatment. Since 2000,three drugs (docetaxel [Taxotere],pemetrexed [Alimta], and erlotinib[Tarceva]) have been approved by theUS Food and Drug Administration(FDA) for second-line therapy in non–small-cell lung cancer (NSCLC) basedon the results of phase III trials (seeTable 1).[1-4] It is also possible thatsimilar approval will be sought for otherdrugs (eg, topotecan [Hycamtin]),[5]and gefitinib (Iressa) remains an optionfor treatment in the third-line setting.

Platinum-based chemotherapy offers a modest survival advantage overbest supportive care in chemotherapy-naive patients with a good performancestatus and advanced/metastatic non–small-cell lung cancer(NSCLC). Despite the survival benefit associated with first-line chemotherapy,the majority of patients will experience relapse or disease progression.In clinical practice, an increasing number of patients maintaina good performance status after first-line treatment and are eligible forfurther treatments. Docetaxel (Taxotere) at 75 mg/m2 given once every3 weeks has been the standard of care for second-line chemotherapy sincethe year 2000. Pemetrexed (Alimta) is a novel multitargeted antifolateagent with single-agent activity in first- and second-line treatment ofNSCLC. A large phase III study comparing docetaxel to pemetrexed insecond-line therapy demonstrated that pemetrexed is equally active andless toxic than docetaxel. Based on these results, pemetrexed is a reasonablesecond-line chemotherapy option for patients with recurrent, advancedNSCLC. Progress made in the field of molecular biology has led to theidentification of drugs active against specific cellular targets. Gefitinib(Iressa) and erlotinib (Tarceva) are both orally active tyrosine kinase inhibitorsof the epidermal growth factor receptor. Phase II and III trialshave demonstrated that these agents are active particularly in a subgroupof patients with specific biologic characteristics. Both drugs have beenapproved for the treatment of pretreated NSCLC. Other drugs, such ascetuximab (Erbitux) and bevacizumab (Avastin) have shown promisingactivity in NSCLC and are currently being tested in clinical trials.

About 172,570 new cases ofnon–small-cell lung cancer(NSCLC) are expected to bediagnosed in 2005 in the United States,and almost as many will die of thedisease. Patients with effusions or metastaticdisease are candidates for combinationchemotherapy. The regimensof choice are platinum-based combinationchemotherapy schedules. Giventhat most patients will experience diseaseprogression despite their initialtreatment, they may be eligible for second-line chemotherapy, provided theyhave an acceptable performance status.

Cappuzzo and colleagues havereviewed the present optionsof salvage therapy for advancednon–small-cell lung cancer(NSCLC). This issue is highly relevantnowadays, as many patients whofail palliative chemotherapy are stillin sufficiently good condition to receiveadditional therapy. It is ratherinstructive to note that 10 years agothe use of systemic chemotherapy foradvanced NSCLC was advocated butstill not standard, and today we haveseveral options for treating patients inthe second- and even third-line setting.Among these options are agents thatspecifically target molecular featuresof lung cancer, such as the epidermalgrowth factor receptor (EGFR)

Statins inhibit the activity of the rate-limiting enzyme in the cholesterolbiosynthetic pathway, HMG-CoA reductase, and are widely prescribedfor lowering plasma lipid levels. Several statins have antitumor effects inexperimental models, and observational studies suggest that this anticanceractivity in the laboratory may translate into effective treatments and/orpreventive strategies for certain human cancers. This paper reviews thelaboratory and clinical evidence that statins have anticancer activity, discussesthe possible mechanisms by which tumor growth may be inhibitedby this class of drugs, and outlines strategies for the evaluation of theseagents in the prevention and treatment of human cancers.

Small-cell lung carcinoma (SCLC) accounts for 20% to 25% of all new cases of lung cancer in the United States. It is estimated that approximately 42,000 new cases will occur in the United States in 1995 [1,2]. Of the various histologic types of lung cancer, small-cell is the most sensitive to chemotherapy and radiotherapy, yet overall outcome is poor, with only 5% to 10% of patients surviving 5 years from diagnosis.

Carcinoma of the breast is the most common cancer in women in the United States and is second only to lung cancer as a cause of cancer death in women. The incidence of breast cancer has risen steadily over the past decade, with the most dramatic increase seen in smaller primary breast tumors, partly because widespread use of screening mammography permits earlier detection [1].
