Lung Cancer

Anticancer drugs have been explored by means of random screening and demonstrated to be active against not only hematologic malignancies but also some solid tumors. Recent progress in the field of molecular biology has

Preclinically, the taxanes appear to potentiate radiation more effectively than do the platinum compounds. In our phase I trial (LUN-17) in patients with advanced non-small-cell lung cancer, we defined the maximum tolerated

We evaluated the feasibility and efficacy of combination paclitaxel (Taxol) (via 1-hour infusion), carboplatin (Paraplatin), and oral etoposide (VePesid) in the first-line treatment of patients with small-cell lung cancer.

Chemotherapeutic intervention in advanced and metastatic non-small-cell lung cancer (NSCLC) has changed over the past 2 decades. The improvements offered by cisplatin (Platinol)-based regimens, though significant in

Lung cancer is the leading cause of death due to cancer in the United States, and approximately 178,100 new cases were estimated to occur last year. Small-cell lung cancer (SCLC) accounts for approximately 17% to 25% of all lung cancers. Due to its aggressive nature and rapid proliferation rate, small-cell lung cancer is usually widespread at diagnosis. Therefore, chemotherapy is the cornerstone of therapy for this disease. Cisplatin (Platinol) is an active chemotherapeutic agent used to treat small-cell lung cancer, but its toxicity, including nausea and vomiting, nephrotoxicity, neurotoxicity, and ototoxicity, has led to the investigation of combination regimens with different toxicity profiles. Carboplatin (Paraplatin), a derivative of cisplatin, has far less nonhematologic toxicity, although myelosuppression may be slightly greater than that observed with cisplatin. The reduced toxicity and equivalent efficacy of carboplatin have resulted in the increased use of carboplatin-based regimens to treat small-cell lung cancer. Phase I and II trials of carboplatin as single-agent treatment for small-cell lung cancer resulted in overall response rates of approximately 60% for previously untreated patients and 17% for those who had received prior therapy. New combination chemotherapy regimens that include carboplatin may improve survival in patients with small-cell lung cancer and potentially cure those patients with limited disease. Further investigation of carboplatin and other new agents is warranted.[ONCOLOGY 12(Suppl 2):36-43, 1998]

The challenge for oncologists treating patients with stage III non-small-cell lung cancer (NSCLC) is to optimize a treatment strategy using nonsurgical therapies. The recognition that chemotherapy response rates for patients

Non-small-cell lung cancer (NSCLC) will increasingly come under better control as the current approaches to therapy are more broadly employed and as new therapies are deployed against recently elucidated molecular

Like other epithelial tumors, non-small-cell lung cancer (NSCLC) is a result of a series of genetic and epigenetic changes that eventually progress to invasive cancer. The order and timing of these changes, involving specific

Prophylactic cranial irradiation (PCI) is being reintroduced into multimodality treatment protocols of patients with small-cell lung cancer (SCLC). The history of its use brings interesting insights into clinical evaluations of treatment strategies and design of relevant and informative trials. The critical issues of effectiveness and overall health gains of prophylactic cranial irradiation have been addressed in a series of recently completed clinical trials. These trials tested prophylactic cranial irradiation in small-cell lung cancer patients achieving good response to induction therapy and confirmed the ability of standard prophylactic cranial irradiation schedules to significantly reduce the lifetime risk of brain metastases. A subset of these trials evaluated neurotoxicity in a formal and prospective manner. No sustained or significant detriment in neuropsychometric function could be linked to the use of prophylactic cranial irradiation. In addition, all the large trials have shown a consistent survival advantage in favor of the prophylactic cranial irradiation arm. None of the individual sample sizes were large enough to statistically confirm this survival benefit, but a meta-analysis is in progress and will report on this aspect of evidence shortly. Issues that remain to be answered are the optimal dose and schedule of prophylactic cranial irradiation as well as the timing of this administration. These questions form the nucleus of the next generation of collaborative trials that are being designed.[ONCOLOGY 12(Suppl 2):19-24, 1998]

The 1997 revision of the lung cancer staging system has added very little to disease staging, and many changes have been totally unnecessary. Before the next revision of the staging system, anticipated in the year 2007, a

Despite advances in the treatment of small-cell lung cancer during the 1970s, with the use of combination chemotherapy, and in the 1980s, with the combination of etoposide and cisplatin plus concurrent radiation

Although the need to combine thoracic radiotherapy with systemic chemotherapy in the curative treatment of limited small-cell lung cancer is now widely acknowledged, there is substantial disagreement on how best to do this. This paper reviews radiotherapeutic factors but also highlights the important interactions that occur with some classes of chemotherapeutics. Studies examining variables like dose and volume are clearly in order. Concurrent therapy given early has been adopted throughout most of the world, except Europe. The reasons for this are explored. Multiple studies are now showing excellent results with fewer total cycles of chemotherapy. Integrationof newer drugs is another challenge for clinical investigators at the close of this century.

We report here the preliminary results of a large phase II multicenter study done in the community setting, using paclitaxel (Taxol) (given by 1-hour infusion) plus carboplatin (Paraplatin) to treat patients with advanced non-small-cell lung cancer (NSCLC). In this study, 155 chemotherapy-naive patients with stage IIIB, stage IV, or recurrent metastatic non-small-cell lung cancer received the two drugs in 21-day cycles. Paclitaxel 225 mg/m² was given by 1-hour intravenous infusion followed immediately by carboplatin at a targeted area under the concentration-time curve of 6.0 (calculated according to the Calvert formula). Colony-stimulating factors were not used routinely. Objective responses occurred in 53 of 155 patients (34%) (53 of 144 [36%] evaluable patients) including three complete responses and 50 partial responses. Fifty-two other patients had stable disease at initial reevaluation. The median survival among all 155 patients was 8 months; the 1-year survival rate was 42%, and the 2-year survival rate was 20%. Leukopenia and cumulative peripheral neuropathy occurred consistently but rarely were severe or affected the course of therapy. One patient died due to sepsis. Other grade 3 and grade 4 toxicities were uncommon. This paclitaxel-carboplatin combination chemotherapy appears to be a relatively convenient, safe, and active regimen in advanced non-small-cell lung cancer.[ONCOLOGY 12(Suppl 2):71-73, 1998]

Topotecan hydrochloride (Hycamtin), as a single agent or in combination with other agents, may offer a new treatment option for people suffering from small-cell lung cancer, according to results from five clinical trials reviewed at the 15th

BETHESDA, Md-A leading medical oncologist laments the refusal of many physicians to even discuss the option of adjuvant chemotherapy with patients who have operable lung cancer. Paul Bunn, Jr., MD, director of the University of Colorado Cancer Center, noted that the first drugs used in lung cancer patients, alkylating agents, actually reduced survival time.

BETHESDA, Md-Rehabilitation techniques, honed over years of experience with patients suffering from chronic obstructive pulmonary disease (COPD), offer the potential to improve the quality of life for lung cancer patients and lower the cost of their care, Andrew L. Ries, MD, said at a workshop sponsored by the Alliance for Lung Cancer Advocacy, Support, and Education (ALCASE) and the International Cancer Alliance. These techniques should be tested further in clinical trials with lung cancer patients, he added.

A study of lung cancer patients led by Duke University investigators and funded by the V Foundation showed chromosome loss in nearly half of those classified as “heavy smokers.”

PHILADELPHIA-The growing use of pulmonary cytology, and consequent increasing experience of cytopath-ologists, has raised the diagnostic accuracy of the five basic pulmonary cytology techniques, Nadia Al-Kaisi, MD, told Oncology News International in an interview after her workshop on the subject at the annual fall meeting of the American Society of Clinical Pathologists (ASCP) and College of American Pathologists (CAP).

Topotecan (Hycamtin) is a promising new topoisomerase I-targeting anticancer agent that first entered clinical trials in 1989 under National Cancer Institute sponsorship in collaboration with SmithKline Beecham. In 1996, it

Anthracycline antibiotic use is limited by cardiac toxicity. The risk factors are cumulative dose, radiation to the chest and mediastinum, age, and preexisting myocardial impairment. Dexrazoxane (Zinecard) can prevent

During the past 5 years, real strides have been made in the management of advanced non-small-cell lung cancer (NSCLC). The introduction of newer chemotherapeutic agents and novel treatment regimens is paving the way for marked improvements in both clinical outcomes and quality of life.

Paclitaxel (Taxol) and vinorelbine (Navelbine) are both microtubule toxins but with opposite mechanisms of action. Paclitaxel promotes the assembly of microtubules, whereas vinorelbine prevents microtuble assembly.

Data from North American clinical trials have shown that vinorelbine (Navelbine) is well tolerated when used as a single agent for the treatment of non-small-cell lung cancer, advanced breast cancer, or ovarian cancer. Myelosuppression is the primary dose-limiting toxicity.

Cisplatin (Platinol) has played a major role in the treatment of non-small-cell lung cancer (NSCLC). As a single agent, cisplatin has produced a response rate of approximately 21% in a large number of trials.

Chemotherapy has been shown to prolong survival in patients with stage IV non-small-cell lung cancer (NSCLC). However, traditional cisplatin (Platinol)-containing regimens are associated with significant toxicity.
