Maintenance and Consolidation Therapy in Patients with Unresectable Stage III/IV Non‐Small Cell Lung Cancer

Globally, lung cancer is the leading cause of cancer‐related mortality. Current chemotherapy combinations for the first‐line treatment of advanced disease (stage IIIB with malignant pleural effusion/stage IV) and chemoradiotherapy regimens for the treatment of unresectable locally advanced disease (stage IIIA and IIIB without malignant pleural effusion) appear to have reached an efficacy plateau. The addition of new compounds including targeted agents to standard first‐line cytotoxic doublets, administered concurrently and/or as maintenance therapy in patients who have not experienced disease progression after such treatment, has been shown to improve efficacy beyond this plateau in patients with advanced disease. However, to date, such approaches have been less successful in the treatment of patients with unresectable locally advanced stage III disease. The purpose of this review is to summarize the data from recent randomized phase III studies involving agents administered as maintenance or consolidation therapy in the treatment of unresectable stage III/IV non‐small cell lung cancer (NSCLC). A possible alternative approach to the use of cytotoxic or molecularly targeted agents in this setting is the administration of therapeutic anticancer vaccines, which are designed to stimulate a host immunological response against the tumor. Current data in relation to the potential of vaccine therapy for NSCLC are therefore also reviewed, with a particular focus on belagenpumatucel‐L and L‐BLP25 vaccines, which are currently undergoing phase III evaluation as maintenance therapies in patients with unresectable stage III/IV NSCLC who have tumor control following first‐line therapy.     

A phase III randomised study comparing two different dose-intensity regimens as induction chemotherapy followed by thoracic irradiation in patients with advanced locoregional non-small-cell lung cancer.

PURPOSE: The aim of this study was to determine the role of chemotherapy dose intensity in patients with initially unresectable non-metastatic non-small-cell lung cancer (NSCLC), with survival as primary end point, by testing two different regimens as induction chemotherapy followed by thoracic irradiation. PATIENTS AND METHODS: Patients had pathologically proven NSCLC, an initially unresectable non-metastatic tumour without homolateral malignant pleural effusion, no prior history of malignancy and had received no prior therapy. Treatment was randomised for chemotherapy between three courses of MIP (mitomycin C 6 mg/m2; ifosfamide 3 g/m2; cisplatin 50 mg/m2) or SuperMIP (mitomycin C 6 mg/m2; ifosfamide 4.5 g/m2; cisplatin 60 mg/m2, carboplatine 200 mg/m2), followed by chest irradiation (60 Gy; five times per week, for 6 weeks). If the tumour became resectable after chemotherapy, surgery was performed, followed by mediastinal irradiation. RESULTS: A total of 351 patients were eligible: 176 in the MIP arm and 175 in the SuperMIP arm, with 43% and 51% stages IIIA and IIIB, respectively. There was a significantly higher objective response rate with SuperMIP (46%) compared with MIP (35%) (P=0.03) [95% confidence interval (CI) for the difference between the response rates, 1% to 22%]. After induction chemotherapy, surgery was performed in 54 (15%) patients (27 per arm) and chest irradiation in 203 (57%) patients (102 in the MIP arm and 101 in the SuperMIP). In terms of survival, there was no statistically significant difference between the two study arms (P=0.16), with median survival times of, for MIP and SuperMIP, respectively, 12.5 (95% CI 10.1-14.9) and 11.2 (95% CI 9.7-12.8) months. Haematological toxicity and dosage reductions were higher with SuperMIP, which was nevertheless associated with a significantly increased absolute dose intensity. CONCLUSIONS: High dose-intensity induction chemotherapy does not improve survival in initially unresectable non metastatic NSCLC.

Phase II study of three-dimensional conformal radiotherapy and concurrent mitomycin-C,vinblastine, and cisplatin chemotherapy for Stage III locally advanced,unresectable, non-small-cell lung cancer

PURPOSE: To evaluate the feasibility, treatment outcome, and toxicity of hyperfractionated three-dimensional conformal radiotherapy (CRT) and concurrent mitomycin-C, vinblastine, and cisplatin (MVP) chemotherapy in locally advanced, unresectable, Stage III non-small-cell lung cancer (NSCLC). METHODS AND MATERIALS: Between August 1993 and December 1996, 161 patients with unresectable Stage III NSCLC were entered into this trial, and 146 (91%) completed the treatment. Hyperfractionated RT was given to a total dose of 64.8-70 Gy (1.2 Gy/fraction, b.i.d.) with two cycles of concurrent MVP chemotherapy (mitomycin-C 6 mg/m(2) on Days 2 and 29, vinblastine 6 mg/m(2) on Days 2 and 29, and cisplatin 60 mg/m(2) on Days 1 and 28). Of the 146 patients who completed the treatment, 78 received noncoplanar three-dimensional CRT using 4-6 fields and 17 received coplanar-segmented CRT. The clinical tumor response was assessed 1 month after RT completion by CT. Toxicity was graded using the Southwestern Oncology Group criteria. The normal tissue complication probability for the lung was calculated to determine the correlation with radiation pneumonitis, if any. Nineteen (13%) had Stage IIIA and 127 (87%) had IIIB disease, including 16 patients with pleural effusion and 20 with supraclavicular lymph node metastasis. RESULTS: The response rate was 75%, composed of 22% complete responders and 53% partial responders. With a minimal follow-up of 45 months, the overall survival rate was 51.2% at 1 year, 25.1% at 2 years, and 14.8% at 5 years; the median survival was 12 months. Patients achieving a complete response (n = 32) had a 2-year overall survival rate of 49.8% and a 5-year survival rate of 39.2% compared with 22.5% and 11.4%, respectively, for the partial responders (n = 78; p = 0.0001). The actuarial local progression-free survival rate for all patients was 65.4% at 1 year, 42.1% at 2 years, and 36.3% at 4 years, and the actuarial distant-free survival rate was 65.4% at 1 year, 42.1% at 2 years, and 36.2% at 5 years. Severe weight loss (>10%) occurred in 20 (13.7%) of the 146 patients during treatment, 42 patients (29%) developed radiation pneumonitis (29 Grade 1 and 13 Grade 2). The average normal tissue complication probability value of the patients who had radiation pneumonitis was significantly greater than that of patients without pneumonitis (66.0% vs. 26.4%). Four patients died of treatment-related toxicity. CONCLUSION: Hyperfractionated three-dimensional CRT and concurrent chemotherapy, as described here, is a well-tolerated regimen with acceptable toxicity. More effective treatment schemes are required to improve local disease control and overall survival.     

Induction chemotherapy with cisplatin and gemcitabine followed by concurrent chemoradiation with twice-weekly gemcitabine in unresectable stage III non-small cell lung cancer: final results of a phase II study

Concurrent chemoradiotherapy (CCR) followed or preceded by full-dose chemotherapy seems to be a standard treatment for unresectable non-small cell lung cancer (NSCLC). Gemcitabine is a strong radiosensitizer, and a phase I study confirmed the feasibility of CCR with low-dose gemcitabine administered twice-weekly in NSCLC patients. Consequently, we designed a prospective, multicentric, phase II trial to evaluate the efficacy and toxicity of this approach, following induction chemotherapy with cisplatin and gemcitabine. We included patients with unresectable stage III NSCLC, no pleural effusion, adequate pulmonary, renal, liver and hematological functions, Karnofsky index >70 and planned treated volume (PTV) <2200cm3. Treatment consisted of 3 cycles of cisplatin (100mg/m2, d1) and gemcitabine (1250mg/m2, d1 and 8) q3w, followed by CCR (gemcitabine 50mg/m2 on Mondays and Thursdays and radiotherapy 68.4Gy, 1.8Gyqd). After the inclusion of 22 patients (group A), an unacceptable toxicity was detected. Thus, cisplatin dose was reduced to 70mg/m2, and gemcitabine dose was adjusted to 35mg/m2 during CCR. Another 34 patients (33 eligible, group B) were included. Five patients in group A and 6 patients in group B discontinued the study treatment during induction. Thus, 17 and 27 patients, respectively initiated CCR. Hematological toxicity (grades III and IV) was particularly relevant in group A during this phase, with 35 and 23% of thrombopenia and neutropenia, respectively. Nonhematological grades III-IV toxicity of chemoradiation was significant and similar in groups A and B: esophagitis 35.2 and 33.3% and pneumonitis 23.5 and 25.9%, respectively. 40.9% of patients in group A vs. 57.5% in group B completed treatment. Overall response (intention-to-treat analysis) was 68.1% in group A and 63.5% in group B. Median survival was 17.7 months for the whole group with a mean follow-up of 41.2 months. 20% of patients were alive at 3 years. Long-term results of this schedule are encouraging. However, nonhematological toxicity of chemoradiation is substantial and different strategies should be tested to minimize it.     

A phase II trial of the combination of gemcitabine, ifosfamide and cisplatin in the treatment of advanced non-small cell lung cancer

OBJECTIVE: This phase II trial was designed to assess the efficacy and toxicity profile of the combination of gemcitabine, ifosfamide and cisplatin (GIP) in the treatment of patients with locally advanced or metastatic non-small cell lung cancer (NSCLC). PATIENTS AND METHODS: Patients included in the study were those with surgically unresectable or metastatic NSCLC, with bidimensionally measurable disease, a Karnofsky performance status > 60, and who had not received previous chemotherapy. Treatment consisted of 1000 mg/m(2) gemcitabine on days 1 and 8, 3 g/m(2) ifosfamide on day 1, and 50 mg/m(2) cisplatin on day 1, administered in 21-day cycles. A maximum of six cycles were administered. RESULTS: Between March 1996 and December 1997, 60 patients were included in the study (37 stage III and 23 stage IV), of which 59 were evaluated for response. An objective response was obtained in 43% of patients (3% complete and 40% partial responses), whereas 22% had stable disease. The median survival time for the whole group was 52 weeks (65 weeks in patients with stage III, and 35 weeks in stage IV). The most frequent toxicity was haematological, 56% of patients presented grade 3 or 4 myelotoxicity in one of the cycles, although only seven episodes of febrile neutropenia were recorded in the 255 cycles administered. CONCLUSIONS: The GIP regimen attains response rates similar to those obtained with the gemcitabine plus cisplatin combination used in advanced NSCLC, and had an acceptable toxicity profile.     

Multicenter phase II trial of accelerated cisplatin and high-dose epirubicin followed by surgery or radiotherapy in patients with stage IIIa non-small-cell lung cancer with mediastinal lymph node involvement (N2-disease)

To assess the therapeutic activity of accelerated cisplatin and high-dose epirubicin with erythropoietin and G-CSF support as induction therapy for patients with stage IIIa-N2 non-small-cell lung cancer (NSCLC). Patients with stage IIIa-N2 NSCLC were enrolled in a phase II trial. They received cisplatin 60 mg m(-2) and epirubicin 135 mg m(-2) every 2 weeks for three courses combined with erythropoietin and G-CSF. Depending on results of clinical response to induction therapy and restaging, patients were treated with surgery or radiotherapy. In total, 61 patients entered from March 2001 to April 2004. During 169 courses of induction chemotherapy, National Cancer Institute of Canada (NCI-C) grade III/IV leucocytopenia was reported in 35 courses (20.7%), NCI-C grade III/IV thrombocytopenia in 26 courses (15.4%) and NCI-C grade III/IV anaemia in six courses (3.6%). Main cause of cisplatin dose reduction was nephrotoxicity (12 courses). Most patients received three courses. There were no chemotherapy-related deaths. Three patients were not evaluable for clinical response. Twenty-eight patients had a partial response (48.3%, 95% CI: 36-61.1%), 24 stable disease and six progressive disease. After induction therapy, 30 patients underwent surgery; complete resection was achieved in 19 procedures (31.1%). Radical radiotherapy was delivered to 25 patients (41%). Six patients were considered unfit for further treatment. Median survival for all patients was 18 months. Response rate of accelerated cisplatin and high-dose epirubicin as induction chemotherapy for stage IIIa-N2 NSCLC patients is not different from more commonly used cisplatin-based regimen.     

不可切除Ⅲ A(N2)期非小细胞肺癌的术前化疗

目的探讨不能切除的ⅢA（N2）期非小细胞肺癌（NSCLC）的治疗方法。方法1999年1月至2002年12月,76例不可切除ⅢA（N2）期NSCLC患者接受诺维苯（NVB,25mg／m^23,第1,5天）加卡铂（300mg／m^2,第1天）2个周期的化疗,第二周期化疗后3周重新评估能否手术切除。对化疗效果达到部分有效（PR）或完全有效（CR）、估计能完全切除的64例患者行剖胸探查术;对化疗后评价为稳定（SD）和进展（PD）的12例患者行放疗。64例手术患者中,完全切除（肺叶或全肺切除加纵隔淋巴结清扫术,至少达到R3水平）56例,术后继续给予诺维苯加卡铂化疗2个周期;不完全切除8例,另加局部放疗。结果76例不可切除的ⅢA（N2）期NSCLC经诱导化疗后手术或放疗,中位生存期为18．6个月,1,2,3年生存率分别为64．2％、39．4％和25．6％。其中完全切除患者的中位生存期为28．2个月,1,2,3年生存率分别为70．4％、52．5％和38．6％。结论对不可切除的局部晚期NSCLC,如诱导化疗后可以手术,应首选外科治疗。     

Induction chemotherapy followed by concurrent chemoradiation for patients with non-operable stage III non-small-cell lung cancer

Combined modality treatment with chemotherapy (CT) and radiotherapy (RT) in stage III non-small-cell lung cancer is considered as standard therapy. As concomitant CT appears to be beneficial, the choice of anticancer agents and the role of induction chemotherapy is still unresolved. We present our experience based on an induction CT scheme with carboplatin plus paclitaxel followed by RT and concomitant CT. 31 patients with non-operable stage IIIA or IIIB NSCLC without pleural effusion were included in this study: 30 males, 1 female; median age 66 years (range: 50-81); 32% with non-operable stage IIIA and 68% with stage IIIB without pleural effusion; 61% squamous cell carcinoma, 32% adenocarcinoma and 7% other histologies. Regarding performance status (PS), 9.7% PS 0 and 90% PS 1 were included. Patients received 3 courses of induction CT with carboplatin AUC=6 and paclitaxel 175 mg/m(2), administrated i.v. on day 1 of each 21-day cycle, followed by thoracic irradiation (total dose 60-65 Gy, daily fractions 1.8-2 Gy) with two concurrent courses of carboplatin/paclitaxel. 16.2% of the patients achieved complete response, 48.4% partial response, 25.8% stable disease and 9.6% progression of disease. Median progression-free and overall survival was 12 and 18 months, respectively. The most frequent haematological toxicities were grade (G) 3 anaemia in 19.3%, G3 neutropenia in 9.6% and G4 neutropenia in 12.9%. Esophageal G2 toxicity (RTOG) was observed in 28.1% of cases. The induction CT followed by concomitant chemoradiation used in this study appears feasible, safe and effective when administered to an unselected inoperable NSCLC stage III patient cohort in the everyday routine clinical practice. Further, our results are comparable to previously published phase III studies.     

Toxicity of FED chemotherapy in non-small-cell lung cancer

Twenty-eight patients with metastatic and/or recurrent non-small-cell lung cancer were treated with a new sequential combination of escalating doses of cisplatin (50, 75, and 100 mg/m2 IV X 1) followed by 5-FU infusion (40 mg/m2/hour X 72) and etoposide (80 mg/m2/day X 3). Three patients received concurrent external radiation therapy. Eleven of the 28 (39%) had a partial response to chemotherapy. Four others had a minor response. One partial responder became a complete responder by surgical excision of residual cancer. Median time to response was 6 weeks followed by a median response duration of 4 months. In responders, chemotherapy was discontinued at the time of maximal response. Median survival was 7 months. Chemotherapy was well tolerated with absence of leucopenia, thrombocytopenia, and nausea and vomiting in a majority of courses. The common toxicities were alopecia (100%), leucopenia (35%), nausea and vomiting (30%), and electrolyte imbalances (27%). Reversible nephrotoxicity, thrombocytopenia, anemia, mucositis, and diarrhea were infrequent. The response rate in stage IV was less than in stage III. The combination of moderate doses of cisplatin, 5-FU infusion, and etoposide provides a new palliative chemotherapy that is well tolerated with concurrent/sequential radiation therapy and may be useful in the multimodality treatment of non-small-cell lung cancer.     

Combined intrapleural and intravenous chemotherapy,and pulmonary irradiation,for treatment of patients with lung cancer presenting with malignant pleural effusion. A pilot study

OBJECTIVES: Patients with non-small-cell lung cancer (NSCLC) and malignant pleural effusion (MPE) are difficult to manage clinically and have a short life expectancy. In this pilot study, we designed a protocol of combined intrapleural (i.p.) and intravenous (i.v.) chemotherapy and pulmonary irradiation to enhance local as well as systemic control of the disease. METHODS: From April 1998 to April 2000, 27 patients with NSCLC and symptomatic MPE were eligible for the study. Patients received pre-radiation chemotherapy (cisplatin 60 mg/m(2) i.p. on day 1; gemcitabine 1,000 mg/m(2) i.v. on days 1, 8, and 15, q4week x 3) after surgical implantation of i.p. and i.v. port-A, followed by radiotherapy (7,020 cGy/39fr), and, finally, post-radiation chemotherapy (docetaxel 60 mg/m(2) q3week x 3-6 i.v.). RESULTS: Grade 1/2 nausea/vomiting and impaired renal function were more common from pre-radiation than post-radiation chemotherapy; however, grade 3/4 toxicities from pre-radiation chemotherapy were minimal. Conversely, grade 3/4 leukopenia and grade 1/2 alopecia, diarrhea, elevation of SGOT/SGPT, and sensory impairment were more common following post-radiation chemotherapy. Only two patients experienced recurrence of pleural effusion. The overall response rate was 55% with 7% complete remission, 48% partial remission, 22% stable disease, and 22% progressive disease. The median failure-free and overall survival was 8 and 16 months, respectively. The one-year survival rate was 63% (95% confidence interval, 45-80%). CONCLUSIONS: We conclude that the combination of i.p. and i.v. chemotherapy and pulmonary irradiation is feasible and should be tested in a larger clinical trial to determine whether survival can be improved for this cohort of patients.     

A randomised phase III trial comparing consolidation treatment with further chemotherapy to chest irradiation in patients with initially unresectable locoregional non-small-cell lung cancer responding to induction chemotherapy

Purpose: A phase III randomised trial was conducted in patients with non-metastatic unresectable non-small-cell lung cancer in order to compare, in responders to induction chemotherapy, consolidation treatment by further chemotherapy to chest irradiation.Patients and methods: A total of 462 untreated NSCLC patients were eligible for three courses of induction chemotherapy (MIP) consisting of cisplatin (50 mg/m2), ifosfamide (3 g/m2) and mitomycin C (6 mg/m2). It was proposed that objective responders be randomised to either three further courses of MIP or to chest irradiation (60 Gy; 2 Gy per fraction given over six weeks).Results: An objective response rate of 35% was achieved; 115 patients (including 52% with initial stage IIIA and 44% with initial stage IIIB) were randomised to consolidation treatment, 60 of them to further chemotherapy and 55 to chest radiotherapy. There was no significant difference in survival between the two arms, with a respective median and two-year survival of 42 weeks (95% confidence intervals (95% CI): 35–51) and 18% (95% CI: 8–28) for chemotherapy and 54 weeks (95% CI: 43–73) and 22% (95% CI: 11–33) for irradiation. There was also no statistical difference for response duration between the two arms but chest irradiation was associated with a significantly greater duration of local control than chemotherapy (median duration times: 158 vs. 31 weeks, P = 0.0007).Conclusions: For non-metastatic unresectable NSCLC treated by an induction chemotherapy regimen containing cisplatin and ifosfamide, if an objective response is obtained, consolidation treatments by further chemotherapy or by chest irradiation result in non-statistically different survival distributions, although a better local control duration is observed with radiotherapy.     

Successful combination therapy with trastuzumab and paclitaxel for adriamycin- and docetaxel-resistant inflammatory breast cancer

We present a case of adriamycin-and docetaxel-resistant inflammatory breast cancer (IBC) in which partial response was achieved with combination therapy using trastuzumab and paclitaxel. A 48-year old woman noticed a lump in her right breast. She was diagnosed with IBC and the disease was staged as T4d N1 M0, stage III B. The patient was started on neoadjuvant chemotherapy with adriamycin (50 mg/m2) and docetaxel (60 mg/m2) administered every three weeks. Six courses were performed and the response was evaluated as no change. After one month, contralateral breast swelling indicated bilateral IBC. Bilatera1 mastectomy using the Halsted method was performed. The immunohistochemical results of the Hercep Test was strongly positive (3+). After the mastectomy, right pleural effusion appeared, and cytological examination revealed the cells to be classV(adenocarcinoma). To treat the clinically advanced breast cancer, combination therapy with trastuzumab (initially 4 mg/kg followed by two or more cycles of 2 mg/kg) and paclitaxel (80 mg/m2) were given intravenously every week for eight cycles and then every two weeks thereafter. A total of 32 courses of therapy were performed, the pleural effusion completely disappeared and partial response was maintained for a duration of 482 days. The adverse reactions were mild, and it was possible for her to be treated as an outpatient with high quality of life. This report suggests that weekly combination therapy of trastuzumab and paclitaxel was useful for treatment of adriamycin-and docetaxel-resistant metastatic breast cancer.     

Induction chemotherapy followed by concurrent standard radiotherapy and daily low-dose cisplatin in locally advanced non-small-cell lung cancer.

Both induction chemotherapy and concurrent low-dose cisplatin have been shown to improve results of thoracic irradiation in the treatment of locally advanced non-small-cell lung cancer (NSCLC). This phase II study was designed to investigate activity and feasibility of a novel chemoradiation regimen consisting of induction chemotherapy followed by standard radiotherapy and concurrent daily low-dose cisplatin. Previously untreated patients with histologically/cytologically proven unresectable stage IIIA/B NSCLC were eligible. Induction chemotherapy consisted of vinblastine 5 mg m(-2) intravenously (i.v.) on days 1, 8, 15, 22 and 29, and cisplatin 100 mg m(-2) i.v. on days 1 and 22 followed by continuous radiotherapy (60 Gy in 30 fractions) given concurrently with daily cisplatin at a dose of 5 mg m(-2) i.v. Thirty-two patients were enrolled. Major toxicity during induction chemotherapy was haematological: grade III-IV leukopenia was observed in 31% and grade II anaemia in 16% of the patients. The most common severe toxicity during concurrent chemoradiation consisted of grade III leukopenia (21% of the patients); grade III oesophagitis occurred in only two patients and pulmonary toxicity in one patient who died of this complication. Eighteen of 32 patients (56%, 95% CI 38-73%) had a major response (11 partial response, seven complete response). With a median follow-up of 38.4 months, the median survival was 12.5 months and the actuarial survival rates at 1, 2 and 3 years were 52%, 26% and 19% respectively. The median event-free survival was 8.3 months with a probability of 40%, 23% and 20% at 1, 2 and 3 years respectively. Induction chemotherapy followed by concurrent daily low-dose cisplatin and thoracic irradiation, in patients with locally advanced NSCLC, is active and feasible with minimal non-haematological toxicity. Long-term survival results are promising and appear to be similar to those of more toxic chemoradiation regimens, warranting further testing of this novel chemoradiation strategy.     

Randomized phase III study of gemcitabine and vinorelbine versus gemcitabine, vinorelbine, and cisplatin in the treatment of advanced non-small-cell lung cancer: from the German and Swiss Lung Cancer Study Group.

PURPOSE: To evaluate whether cisplatin-based chemotherapy (gemcitabine, vinorelbine, and cisplatin [GVP]) prolongs overall survival in comparison to cisplatin-free chemotherapy (gemcitabine and vinorelbine [GV]) as first-line treatment in patients with advanced non-small-cell lung cancer (NSCLC). PATIENTS AND METHODS: Between September 1999 and June 2001, 300 patients with NSCLC stage IIIB with malignant pleural effusion or stage IV disease were randomly assigned to receive GV (gemcitabine 1000 mg/m(2) + vinorelbine 25 mg/m(2) on days 1 and 8 every 3 weeks) or GVP (gemcitabine 1000 mg/m(2) + vinorelbine 25 mg/m(2) on days 1 and 8 + cisplatin 75 mg/m(2) on day 2 every 3 weeks). Primary end point of the study was overall survival. RESULTS: Two hundred eighty-seven patients (GV, 143 patients; GVP, 144 patients) were eligible for analysis. At the time of analysis, April 15, 2002, 209 patients (GV, 103 patients; GVP, 106 patients) of 287 patients had died (73%). No statistically significant difference was observed for overall survival (P =.73; median survival, 35.9 versus 32.4 weeks; 1-year survival rate, 33.6% versus 27.5%) as well as for event-free survival (P =.35; median time-to-event, 19.3 versus 22.3 weeks) between GV and GVP. Two hundred fourteen patients were assessable for best response. The overall response rates were 13.0% for GV versus 28.3% for GVP (P =.004; complete responders, 0% versus 3.8%; partial responders, 13.0% versus 24.5%). Hematologic and nonhematologic toxicity was significantly lower in the GV treatment arm compared with GVP. No statistically significant difference in quality of life was observed. CONCLUSION: In this phase III study, the cisplatin-based GVP regimen showed no survival benefit as first-line chemotherapy in advanced NSCLC when compared with the cisplatin-free GV regimen, which was substantially better tolerated.     

Rational drug sequencing of paclitaxel, gemcitabine and carboplatin in patients with untreated stage IV and select stage IIIB non-small cell lung cancer

INTRODUCTION: To conduct a phase II study evaluating the efficacy of rationally sequenced paclitaxel, gemcitabine, and carboplatin in patients with stage IV or select stage IIIB non-small cell lung cancer (NSCLC). METHODS: Patients with select stages IIIB (pleural effusion) and IV NSCLC with an ECOG performance status of 0-1 and no prior chemotherapy for their disease were eligible to participate. Treatment was delivered as follows: paclitaxel at 70 mg/m2 followed by gemcitabine at 300 mg/m2 on day 1, with carboplatin (AUC 5) on day 2 of a 28-day cycle. Response was assessed after every two cycles of therapy. The primary endpoint of this trial was response rate, with secondary endpoints of time to progression and 1 year overall survival. RESULTS: Twenty patients were enrolled on protocol, one of whom never received chemotherapy. The median number of cycles delivered was 3 (range 0-8). A partial response rate of 42% (8/19; 95% CI: 20-67%) and a stable disease rate of 11% (2/19; 95% CI: 1-33%) were observed. The median overall survival time was 9.6 months (95% CI: 4.6-16.6), with a 1 year overall survival rate of 42.1% (95% CI: 24.9-71.3%). Eight patients (42%) stopped treatment due to toxicity. CONCLUSION: Paclitaxel followed by gemcitabine and then carboplatin is an active, albeit complex, regimen in the treatment of patients with advanced NSCLC with insufficient advantage to justify continuation of this regimen.     

Phase II study of bi-weekly docetaxel and carboplatin with concurrent thoracic radiation therapy followed by consolidation chemotherapy with docetaxel plus carboplatin for stage III unresectable non-small cell lung cancer

OBJECTIVE: Docetaxel and carboplatin (DC) have demonstrated activity as radiation sensitizers in pre-clinical studies. The aim of this phase II study was to evaluate the efficacy and toxicity of DC with concurrent thoracic radiation therapy (TRT) followed by consolidation chemotherapy with DC for stage III unresectable non-small cell lung cancer (NSCLC). PATIENTS AND METHODS: Thirty-three previously untreated patients with inoperable, locally advanced (LA) NSCLC received docetaxel 30 mg/m2 over 1 h and carboplatin at an AUC of 3 every 2 weeks for six courses--four courses during concurrent chemoradiotherapy and two courses following completion of radiotherapy. Concurrent TRT was performed in 2-Gy daily fractions to a total dose of 60 Gy. RESULTS: Among 32 evaluable patients, the overall response rate was 91%, with two complete responses (CR) and 27 partial responses (PR). Median survival time by intention-to-treat analysis was 27 months, with survival rates of 76% at 1 year and 61% at 2 years. Serious side effects were generally limited to grade 3 neutropenia in 6%, grades 3 and 4 pulmonary toxicity in 6 and 3%, respectively, and grade 3 esophagitis in 3% of patients. CONCLUSIONS: DC with concurrent TRT followed by consolidation chemotherapy was highly active with manageable toxicity in patients with stage III unresectable NSCLC.     

A case of large-cell lung cancer with liver metastasis successfully treated using combination chemotherapy with CDDP and vinorelbine

A 38-year-old woman presented to our hospital with the chief complaint of dyspnea. A chest radiograph showed pleural effusion of the right lung and a CT scan revealed liver metastasis. A tumor biopsy done under bronchoscopy revealed large-cell carcinoma of the lungs. She was given 4 courses of a combination therapy consisting of CDDP (80 mg/m2) and vinorelbine (25 mg/m2). The primary tumor in the right lung and liver metastasis were markedly reduced in size and a partial response was obtained. The combination therapy of CDDP and vinorelbine may become a standard chemotherapy for advanced non-small cell lung cancer.
