Cost-minimization analysis for Portugal of five doublet chemotherapy regimens from two phase III trials in the treatment of advanced non-small cell lung cancer.

OBJECTIVES: Economic evaluations of chemotherapy regimens for stage IIIB or IV non-small cell lung cancer (NSCLC) have been conducted for many European countries, but not for Portugal. This study evaluates the total health care costs of five commonly used doublet regimens with similar efficacy results. METHODS: Using the methodology reported by Schiller [Schiller JH, Tilden D, Aristides M, Lees M, Kielhorn A, Maniadakis N, et al. Restropective cost analysis of gemcitabine in combination with cisplatin in non-small cell lung cancer compared to other combination therapies in Europe. Lung Cancer 2004;43:101-12], we conducted a cost-minimization analysis to compare vinorelbine-cisplatin (Vin/Cis), gemcitabine-cisplatin (Gem/Cis), paclitaxel-carboplatin (Pac/Carb), docetaxel-cisplatin (Doc/Cis), and paclitaxel-cisplatin (Pac/Cis). The perspective was that of the Portuguese National Health Service and included only direct medical costs (reimbursed costs plus co-payments): chemotherapy acquisition, chemotherapy administration, hospitalizations due to adverse events, and other medical resources. Unit costs were drawn from official sources (Diagnosis Related Groups and retail/hospital costs) (2003 value [Diagnosis Related Groups (DRG) published at Diário da República; 2003]). Resource use was estimated from two multicenter randomized phase III trials [Comella P, Frasci G, Panza N, Manzione L, De Cataldis G, Cioffi R, et al. Randomized trial comparing cisplatin, gemcitabine, and vinorelbine with either cisplatin and gemcitabine or cisplatin and vinorelbine in advanced non-small-cell lung cancer: interim analysis of a phase III trial of the Southern Italy Cooperative Oncology Group. J Clin Oncol 2000;18:1451-7; Schiller JH, Harrington D, Belani CP, Langer C, Sandler A, Krook J, et al. Comparison of four chemotherapy regimens for advanced non-small-cell lung cancer. N Engl J Med 2002;346:92-8]. A time horizon of a full course of therapy was adopted. One-way sensitivity analyses were performed. RESULTS: The least and the most costly chemotherapy regimens were Gem/Cis and Pac/Carb, respectively. Total mean cost per patient was estimated at euro7083 for Gem/Cis and euro10,008 for Pac/Carb, a mean cost savings of euro2925 per patient for Gem/Cis. The differences were mainly due to the higher chemotherapy acquisition costs of Pac/Carb than for Gem/Cis. Gem/Cis was less costly in all sensitivity analyses except when 100% inpatient chemotherapy administration was assumed. CONCLUSION: Gem/Cis should be considered as a cost-saving alternative to the other four regimens in treating NSCLC patients in Portugal.

Three sequential chemotherapy doublets for the treatment of newly diagnosed advanced müllerian malignancies: the modified triple doublet regimen.

OBJECTIVE: Previously, we reported the use of three sequential doublets (Triple Doublets) in the treatment of women with newly diagnosed and advanced stage müllerian malignancies. The surgically defined negative second look operation (SLO) rate to Triple Doublets was 38%. Modifications were made to this treatment regimen that were predicted to reduce toxicity and possibly increase efficacy. METHODS: Open label two-cohort study. Patients with a new diagnosis of Stages II-IV müllerian malignancy were eligible. After cytoreductive surgery, patients were treated with three sequential doublets including 3 cycles of carboplatin and gemcitabine, and 3 cycles of carboplatin and paclitaxel, and 3 cycles of doxorubicin and topotecan. After therapy, all women were clinically staged and evaluated at SLO if clinical staging was negative for residual disease. Primary endpoints were toxicity and negative SLO rate with rates of 60% and 40% defined a priori in optimally cytoreduced (cohort 1) and suboptimally cytoreduced or Stage IV (cohort 2), respectively. RESULTS: Eighty-five eligible patients were enrolled with a median age of 52 years. Forty-seven and thirty-eight women were in cohorts 1 and 2, respectively. 723 cycles of chemotherapy were delivered with no toxic deaths. Grades 3 and 4 toxicities included neutropenia in 75% of patients and thrombocytopenia in 65% of patients during at least one cycle of therapy. Fever and neutropenia were seen in 3.5% of patients. All Grades 3 and 4 non-hematologic toxicities were seen at a frequency of <10%. Seventy women underwent SLO with a negative SLO rate of 53% with an additional 9% having microscopically positive procedures. Negative SLO rate was 74% in cohort 1 and 36% in cohort 2. CONCLUSIONS: Treatment with the modified triple doublet regimen is tolerable with an encouraging pathologic CR rate.

Randomized phase-II trial of surufatinib plus FOLFOX/FOLFIRI versus FOLFOXIRI as second-line therapy for metastatic colorectal cancer.

BACKGROUND: Second-line treatment for metastatic colorectal cancer (mCRC) typically involves oxaliplatin- or irinotecan-based doublet chemotherapy with or without anti-angiogenic antibodies. Triplet regimens such as FOLFOXIRI have demonstrated synergy and improved efficacy as first-line therapy. Surufatinib, an oral multi-kinase inhibitor targeting VEGFR1-3, FGFR1, and CSF-1R, may enhance chemotherapy efficacy. We evaluated surufatinib combined with doublet (FOLFOX/FOLFIRI) versus triplet (FOLFOXIRI) chemotherapy as second-line treatment for mCRC. PATIENTS AND METHODS: This multicentre, open-label, randomized phase-II trial used Simon's minimax two-stage design. Eligible patients had mCRC progressing on or within 6&#x2009;months after first-line doublet chemotherapy. Patients were randomized 1:1 to surufatinib 250&#x2009;mg once daily plus either mFOLFOX6/FOLFIRI (doublet cohort, selected based on prior regimen) or FOLFOXIRI (triplet cohort). The primary endpoint was objective response rate (ORR). RESULTS: From September 2021 to November 2023, 57 patients were randomized (28 per cohort after one withdrawal). In the doublet cohort, ORR was 35.7% (95% CI: 18.6-55.9), median progression-free survival (PFS) was 5.4&#x2009;months (95% CI: 3.8-7.0), and median overall survival (OS) was 19.0&#x2009;months (95% CI: 9.2-28.8). In the triplet cohort, ORR was 39.3% (95% CI: 21.5-59.4), median PFS was 5.8&#x2009;months (95% CI: 3.3-8.2), and median OS was 10.9&#x2009;months (95% CI: 6.0-15.8). Grade &#x2265;3 treatment-emergent adverse events occurred more frequently in the triplet (71.4%) versus doublet (57.1%) cohort, with higher rates of treatment delays (89.3% versus 72.0%) and discontinuations (25.0% versus 14.3%). CONCLUSIONS: Surufatinib plus doublet chemotherapy showed encouraging antitumor activity and acceptable tolerability in second-line mCRC, warranting further evaluation in a larger randomized trial. In contrast, surufatinib plus triplet chemotherapy was associated with increased toxicity, more frequent treatment delays or discontinuations, and shorter overall survival; this combination is not recommended for further investigation in this setting.ClinicalTrials.gov: NCT04734249Date of registration: January 31, 2021.

Phase II study of neoadjuvant chemotherapy with gemcitabine and vinorelbine in resectable non-small cell lung cancer.

OBJECTIVE: We assessed the efficacy of a non-platinum-containing doublet chemotherapy of gemcitabine and vinorelbine as induction therapy prior to surgical resection in patients with stage IB-IIIA and selected stage IIIB non-small cell lung cancer (NSCLC). The primary clinical end point was radiographic disease response rate, and the secondary end points were pathologic response rate, treatment-related toxicity, surgical resectability and outcome, and overall and disease-free survival. METHODS: Patients underwent staging with CT of the chest and upper-abdomen, whole-body F-18 fluorodeoxyglucose positron emission tomography, bronchoscopy, and mediastinoscopy. The patients had to have medically and surgically resectable disease. Chemotherapy consisted of gemcitabine, 1,000 mg/m(2), and vinorelbine, 25 mg/m(2), administered on days 1, 8, 22, and 29. Imaging studies were repeated between days 43 and 50. Disease response was assessed by response evaluation criteria in solid tumors, and patients with resectable disease were offered surgery between days 50 and 70. Patients were followed up every 3 months for 2 years with chest CT. RESULTS: Between January 2000 and March 2004, 27 patients with stage IB NSCLC, 15 patients with stage II NSCLC, and 20 patients with stage III NSCLC were entered. After induction chemotherapy 34% (95% confidence interval [CI], 23 to 48%) had an objective radiographic response, 2% had a complete pathologic response, 90% underwent thoracotomy, and 77% underwent a complete resection. There were four deaths in the 6-week period following surgery, and there were no deaths related to chemotherapy. There were no unexpected morbidities from surgery or chemotherapy. The 1-year and 2-year overall survival rates were 80% (95% CI, 68 to 88%) and 65% (95% CI, 50 to 76%), and the median overall survival was 38.2 months. CONCLUSIONS: Induction chemotherapy with gemcitabine and vinorelbine results in 1-year and 2-year survival rates and a median survival time comparable to those obtained with platinum-containing doublets. However, it appears to be less efficacious in terms of radiographic and pathologic response rates compared with platinum-containing chemotherapy doublets.

Treatment of non-small-cell lung cancer: a perspective on the recent advances and the experience with gefitinib.

Worldwide, non-small-cell lung cancer (NSCLC) is a leading cause of cancer-related mortality and, until screening detects early disease, treatment for the majority of patients will consist of radiation therapy, chemotherapy or combinations thereof. Modern mono and doublet chemotherapy regimens have translated into modest increases in life expectancy and improved quality of life, but at the expense of systemic and pulmonary adverse events (AEs). There is a great unmet need to provide effective therapy for advanced NSCLC that does not have the toxicity burden of conventional chemotherapy and radiotherapy. Novel drugs that inhibit a range of growth factor receptors, such as the epidermal growth factor receptor tyrosine kinase inhibitors gefitinib ('Iressa') and erlotinib ('Tarceva') or the monoclonal antibody cetuximab ('Erbitux'), have recently been evaluated. Having demonstrated antitumour activity and rapid symptom improvement in pretreated patients with advanced NSCLC, gefitinib was approved in the USA, Japan and other countries. Gefitinib is well tolerated with a low incidence of grade 3/4 AEs. Interstitial lung disease has been reported in a small number of patients receiving gefitinib, although this may be attributed to other treatments and conditions. Nevertheless, although the use of novel treatments requires vigilance for unexpected AEs such as pulmonary toxicity, in this area of high unmet clinical need, the benefits outweigh the risks in patients for whom no other proven effective treatment exists.

Pemetrexed: its promise in treating non-small-cell lung cancer.

The use of chemotherapy in the treatment of early and advanced non-small-cell lung cancer (NSCLC) has increased during the past decade. One of the main reasons for the increased acceptance of chemotherapy is the development of several new cytotoxic agents with a unique mechanism(s) of action and high single-agent activity, combined with a favorable toxicity profile. Pemetrexed (Alimta) is a novel antifolate that inhibits several enzymes involved in DNA synthesis (thymidylate synthase [TS], dihydrofolate reductase [DHFR], and glycinamide ribonucleotideformyltransferase [GARFT]). Pemetrexed's toxicity is markedly reduced by folic acid and vitamin B12 supplementation. The compound has been studied extensively in various tumor types, including NSCLC. In NSCLC, pemetrexed at 500 mg/m2, every 3 weeks, given i.v. over 10 minutes, has shown promising activity, and can safely be administrated with vitamin supplementation. After registration, single-agent pemetrexed will certainly add to the chemotherapeutic options available for pretreated patients and will most likely change significantly chemotherapy prescriptions in second-line chemotherapy. In first-line chemotherapy, the role of platinum-based and -free combination doublet chemotherapy with pemetrexed still needs to be defined. Phase II data indicate high efficacy combined with favorable toxicity for pemetrexed in combination with cisplatin, carboplatin (Paraplatin), oxaliplatin (Eloxatin), gemcitabine (Gemzar), and vinorelbine (Navelbine). This review summarizes the clinical experience obtained thus far during the early clinical development of pemetrexed in NSCLC.

Successful salvage of relapsed high-risk gestational trophoblastic neoplasia patients using a novel paclitaxel-containing doublet.

OBJECTIVE: To describe one institution's results with a novel 3-drug doublet, consisting of paclitaxel, etoposide and cisplatin, for salvage of relapsed high-risk gestational trophoblastic neoplasia (GTN) patients. STUDY DESIGN: Analysis of treatment results with the doublet regimen in two patients with recurrent/persistent high-risk choriocarcinoma in the Division of Gynecologic Oncology, Toronto-Sunnybrook Regional Cancer Centre, University of Toronto. Both patients had been treated previously with one or more of the doublet drugs. RESULTS: Both patients experienced complete responses, patient 1 for 13 months and patient 2 for 9. Patient 1 required surgical resection of a single focus of recurrence and was again in complete remission 27 months after completing her last course of doublet chemotherapy. Patient 2 has not relapsed since completing the treatment. CONCLUSION: The doublet regimen appears capable of producing a sustained response in patients with recurrent high-risk GTN who have previously undergone extensive chemotherapy. Further, the regimen seems to be reasonably well tolerated.

Targeting non-small cell lung cancer with epidermal growth factor tyrosine kinase inhibitors: where do we stand, where do we go.

Cytotoxic chemotherapy has only yielded modest gains in survival in lung cancer in the past decade. However, the development of agents targeting specific signaling pathways that drive carcinogenesis has heralded a major paradigm shift in the approach to treatment of cancer. In non-small cell lung cancer (NSCLC), many researchers have focused on the epidermal growth factor receptor (EGFR) because this protein is present on a relatively high proportion of non-small cell lung cancers and its intracellular tyrosine kinase activates a signaling cascade that drives tumor growth. Blockade of the EGFR by small molecule inhibitors of the tyrosine kinase, such as gefitinib and erlotinib, causes tumor regressions in NSCLC. Phase II monotherapy trials of EGFR tyrosine kinase inhibitors in patients with previously treated advanced NSCLC demonstrated anti-tumor activity with objective response rates of 10-19% with acceptable toxicities and an associated improvement in lung cancer symptomatology. Gefitinib is now an FDA approved treatment for advanced NSCLC previously treated with platinum and docetaxel-based therapies. However, phase III trials of gefitinib and erlotinib in combination with chemotherapy doublets have failed to demonstrate a survival advantage when compared with chemotherapy alone. It remains unclear why these drugs work so effectively in certain patients and so poorly in combination with chemotherapy. The goal of ongoing and future investigation is to identify which patients may benefit from this new therapeutic approach.

Genetic testing for chemotherapy in non-small cell lung cancer.

Cisplatin or carboplatin is commonly used with gemcitabine, docetaxel, paclitaxel, or vinorelbine as chemotherapy doublets in the treatment of advanced non-small-cell lung cancer (NSCLC). Several randomized trials have failed to identify major differences in survival between any of these doublets. This lack of evidence for improvement in survival with any chemotherapy regimen has created a tabula rasa where no more large randomized trials should be conducted without including a genetic analysis. Patients see survival as their major concern, and other considerations, such as cost and quality of life, are relegated to lower positions. Genetic alterations related to the transcription-coupled repair pathway of the nucleotide excision repair system (TC-NER) have revealed the subset of patients who are resistant to cisplatin. TC-NER involves genes that are deficient in rare inborn disorders such as Cockayne syndrome and xeroderma pigmentosum. For a long time, ERCC1 mRNA levels have been known to correlate with DNA repair capacity in various tissues. Levels of DNA cisplatin adducts in peripheral blood and buccal mucosa cells predict chemotherapy response, and high ERCC1 mRNA levels have been related to chemoresistance in ovarian cancer and in malignant lymphocytes from chronic lymphocytic leukemia. Moreover, in some instances, mRNA expression has been correlated with polymorphisms. Overexpression of ERCC1 correlates with poor survival in gemcitabine/cisplatin-treated NSCLC patients. An ongoing customized ERCC1-based chemotherapy trial has been designed based on this knowledge. Patients are randomized to the control arm of cisplatin/docetaxel or to the experimental arm, where docetaxel is combined with cisplatin or gemcitabine according to ERCC1 levels. To date, 86 patients have been included.

Influence of genetic markers on survival in non-small cell lung cancer.

Cisplatin or carboplatin is commonly used with gemcitabine, docetaxel, paclitaxel or vinorelbine as chemotherapy doublets in the treatment of advanced non-small cell lung cancer. Several randomized trials have failed to identify major differences in survival between any of these doublets. This lack of evidence for improvement in survival with any chemotherapy regimen has created a tabula rasa in which no more large randomized trials should be conducted with out including a genetic analysis. Patients see survival as their major concern, and other considerations, such as cost of treatment and qualify of life, are relegated to lower positions. Genetic alterations related to the transcription-coupled repair pathway of the nucleotide excision repair system (TC-NER) have revealed the subset of patients who are resistant to cisplatin. TC-NER involves genes that are deficient in rare inborn disorders such as Cockayne syndrome and xeroderma pigmentosum. For a long time, ERCC1 mRNA levels have been known to correlate with DNA repair capacity in various tissues. Levels of DNA cisplatin adducts in peripheral blood and buccal mucosa cells predict chemotherapy response, and high ERCC1 mRNA levels have been related to chemoresistance in ovarian cancer and in malignant lymphocytes from chronic lymphocytic leukemia. Moreover , in some instances, mRNA expression has been correlated with polymorphisms. Overexpression of ERCC1 correlates with poor survival gemcitabine/cisplatin-treated non-small cell lung cancer patients. An ongoing customized ERCC1-based chemotherapy trial has been established on this knowledge. Patients are randomized to the control arm of cisplatin/docetaxel is combined with cisplatin or gemcitabine according to ERCC1 levels. To date, 80 patients have been included. At the preclinical level, ERCC1 and XPD mRNA expression correlate with each other, and overexpression of XPD causes selective cisplatin resistance in human tumor cell lines. Some XPD polymorphisms have been associated with lower DNA repair capacity. In our experience, time to disease progression is significantly higher in gemcitabine/cisplatin-treated patients with the Lys751Gln genotype (9.6 months) than in those with the Lys751Lys genotype (4.2 months; p = 0.03). Other polymorphisms involved in parallel DNA repair systems may well provide the same information, indicating a high degree of biological redundancy. The overexpression of the subunit M1 of ribonucleotide reductase (RRM1) has been linked to gemcitabine resistance in our retrospective assessment. Preliminary findings indicate that a subset of gemcitabine/cisplatin-treated patients with low ERCC1 and RRM1 mRNA levels show a significantly longer survival. This highlights the possibilities of individually tailored chemotherapy. However, in patients treated with cisplatin/vinorelbine, the opposite effect has been observed. Patients with Lys751Lys had a longer time to progression. When docetaxel was added to gemcitabine/cisplatin, patients with Lys751Lys also had better survival. Our findings indicate that TC-NER status can help to decide between cisplatin/gemcitabine and docetaxel/ cisplatin. TC-NER-dependent activity is similar to other anticancer agents that cause DNA-binding enzymes to kill cells (topoisomerase inhibitors). At least 50% of non-small cell lung cancer patients harbor Lys751Lys and can benefit from docetaxel/ cisplatin treatment. Genes involved in spindle formation, centrosome functions and mRNA transport along the microtubule tracks should provide further information on potential markers of docetaxel resistance.

A phase II trial of three sequential doublets for the treatment of advanced müllerian malignancies.

OBJECTIVES: In an effort to improve the results of primary chemotherapy for müllerian malignancies a novel chemotherapy program was piloted that delivered three sequential chemotherapy doublets. The primary endpoints were surgically defined response rates and evaluation of toxicity. METHODS: After primary cytoreductive surgery patients were treated with three sequential doublets including three initial cycles of carboplatin and paclitaxel (doublet 1) and then two cycles of cisplatin (day 1) and gemcitabine (days 1 and 8; doublet 2), and finally two cycles of doxorubicin (day 1) and topotecan (days 3,4, and 5; doublet 3). Cycles 4 through 7 were given with G-CSF (Neupogen) support at a dose of 5 mcg/kg/day. After therapy, all women were clinically staged and evaluated by second-look laparoscopy/laparotomy (SLO) if clinical staging was negative for residual disease. RESULTS: A total of 49 eligible patients were enrolled with a median age of 52 (SD 9). Forty-four women had either ovarian cancer or primary peritoneal carcinoma with 3 women diagnosed with fallopian tube carcinoma and 2 with papillary serous carcinoma of the uterus. Eighty-four percent of patients had stage IIIc/IV tumors, with 29% having >1 cm residual disease after primary cytoreductive surgery. Thirty-nine of 49 (80%) patients completed therapy. A total of 283 cycles of chemotherapy were delivered with acceptable toxicities. There were no toxic deaths. Five women were withdrawn from trial (3 for Taxol hypersensitivity, 1 for gemcitabine pulmonary hypersensitivity, and 1 for serious line infection). Neutropenia, typically without fever, was relatively frequent in the first doublet. Nausea and thrombocytopenia were the predominant toxicities in doublet 2. Thirty-nine women completed all cycles of treatment. Thirty-six women had restaging results consistent with a clinical complete response (CR) and underwent SLO. The pathologic CR rate of the patients undergoing SLO was 38%. CONCLUSIONS: Treatment with this sequential doublet regimen is feasible with a 38% pathologic CR rate.

Persistent and aggressive treatment for thymic carcinoma. Results of a single-institute experience with 25 patients.

OBJECTIVES: The aim of this study is to retrospectively evaluate the role of several therapies, mainly chemotherapy, for thymic carcinoma (TC). METHODS: From July 1973 to July 2005, 25 patients (15 males and 10 females) with histologically proven TC were treated at our department. The median age of the patients was 59 years, with a range of from 30 to 78 years. According to Masaoka's staging system, there was 1 stage I patient, 3 stage II, 7 stage III, 6 stage IVa, and 8 stage IVb patients. The histological subtype was in all cases squamous cell carcinoma, nonkeratinizing type. RESULTS: There were 6 complete surgical resections, 1 incomplete resection followed by chemoradiotherapy, 6 with radiotherapy alone, 3 with radiotherapy plus chemotherapy, and 9 with chemotherapy alone as the initial treatment. Eighteen patients were administered second-line therapy. The regimen obtaining the best response rate was doublet chemotherapy consisting of carboplatin (CBDCA) and paclitaxel. The median survival time and survival rate at 5 years for the patients excluding surgical cases with stage I/II disease were 32 months and 31%, respectively. CONCLUSION: The doublet of CBDCA and paclitaxel thus appears to be a promising regimen for TC and further investigation in a multi-institutional phase II trial is, therefore, strongly called for.

Combination therapy versus single agent chemotherapy in non-small cell lung cancer.

There is proven evidence of improved symptom control with platinum-based chemotherapy in the palliation of non-small cell lung cancer, and small but definite improvements in progression-free and overall survival when compared with best supportive care. The newer chemotherapy agents vinorelbine, gemcitabine, docetaxel and paclitaxel all have single agent activity, and in combination with cisplatin these provide superior quality of life and/or survival compared with the single agents, albeit with some increase in haematological toxicity. Doublet chemotherapy consisting of a new agent combined with platinum, cisplatin by preference where tolerated, has become the standard of care for advanced disease. The use of a functional assessment of fitness, rather than chronological age alone, is appropriate in the treatment of elderly patients. Although in this group there is evidence that doublets are superior to single agents, treatment should be undertaken with caution. In the second line setting where patients are unlikely to tolerate combination therapy, single agents have proven superiority over best supportive care. Patients with poor performance status (PS2) without comorbidity may tolerate combination therapy, but currently available evidence is insufficient to allow a definitive recommendation for combination or single-agent chemotherapy.

Advances in chemotherapy of non-small cell lung cancer.

In the United States, lung cancer kills more men and woman than the next three most common cancers combined. Unfortunately, the long-term outcome of lung cancer is still dismal with a 5-year survival rate of 15%. However, significant improvements in median survival times and 1-year and 2-year survival rates have been achieved in the last decade. This progress has been accomplished not only because of better surgical techniques but also because of the use of platinum-based regimens with newer chemotherapy agents and, more recently, targeted therapy. The role of chemotherapy as an integral part of the treatment of lung cancer has expanded significantly, particularly in the last few years with the proven benefit of adjuvant chemotherapy. For advanced stage non-small cell lung cancer (NSCLC), chemotherapy prolongs survival and improves quality of life in patients with good performance status, and appears to provide symptomatic improvement in patients with decreased performance status. Platinum-based doublet chemotherapy regimens are now the standard of care in patients with advanced stage NSCLC, and non-platinum-based combination therapies are reasonable alternatives in certain populations. The combination of the vascular endothelial growth factor inhibitor bevacizumab and chemotherapy has proven to prolong survival. As agents such as monoclonal antibodies, small molecules inhibitors of tyrosine kinase, and direct inhibitors of proteins involved in lung cancer proliferation are being developed and tested, we are optimistic that these agents will result in improvement in the survival and quality of life of lung cancer patients.

Postoperative adjuvant therapy for completely resected early-stage non-small cell lung cancer.

Consensus on adjuvant therapy for completely resected non-small cell lung cancer until 2002 was as follows. (1) There was no significant impact of postoperative adjuvant chemotherapy based on meta-analysis and previous clinical trials. (2) Confirmatory studies are necessary in large-scale prospective clinical trials. However, recent mega trials have introduced epoch-making changes for postoperative adjuvant chemotherapy in clinical practice since ASCO 2003. The effectiveness of UFT in N0 patients was confirmed. Patients with completely resected stage I non-small cell lung cancer, especially T2N0 adenocarcinoma, will benefit from adjuvant chemotherapy with UFT. The results of the International Adjuvant Lung Trial (IALT) have confirmed the meta-analysis in 1995. Also, both the JBR10 and Cancer and Leukemia Group B (CALGB) 9633 studies have also confirmed positive IALT results of the benefit for postoperative platinum-based chemotherapy in completely resected non-small cell lung cancer. Adjuvant chemotherapy for pathological stage IB to II, completely resected non-small cell lung cancer is standard care based on clinical trials. UFT showed the strongest evidence for IB in Japan. Platinum doublet chemotherapy with third-generation anticancer agents is also recommended. Adjuvant chemotherapy should be offered as standard care to patients after completely resected early stage non-small cell lung cancer. However, there is no evidence of the feasibility and efficacy for adjuvant chemotherapy with the platinum-based regimen in Japan. Careful management should be necessary in such treatment.

Triplet combination chemotherapy and targeted therapy regimens.

Current agents for the treatment of non-small-cell lung cancer include gemcitabine (Gemzar), paclitaxel (Taxol), docetaxel (Taxotere), vinorelbine (Navelbine), and irinotecan (CPT-11, Camptosar). Experimental agents include pemetrexed (LY231514, Alimta) and tirapazamine. Molecular and biological therapies include angiogenesis inhibitors, epidermal growth factor receptor inhibitors, HER2/neu inhibitors, and inhibitors of ras activation and function. Doublet chemotherapy is currently the standard treatment for advanced non-small-cell lung cancer. In the past 2 years, randomized trials have shown that many of the new two-drug combinations used to treat non-small-cell lung cancer have equivalent efficacy. These combinations produce 1-year survival rates of about 35% and 2-year survival rates of about 15%. Toxicity rates vary but are sufficiently low as to make the development of three-drug combinations feasible. Preliminary studies from several phase I and II trials suggest that triplet therapy can improve survival beyond that of double therapy regimens.
