Randomized phase II study of two intercalated combinations of eribulin mesylate and erlotinib in patients with previously treated advanced non-small-cell lung cancer.

BACKGROUND: This phase II, open-label study investigated intercalated combinations of eribulin and erlotinib in unselected patients with advanced non-small-cell lung cancer previously treated with platinum-based chemotherapies. PATIENTS AND METHODS: Eligible patients were randomized to eribulin mesylate 2.0 mg/m(2) on day 1 with erlotinib 150 mg on days 2-16 (21-day regimen) or eribulin mesylate 1.4 mg/m(2) on days 1 and 8 with erlotinib 150 mg on days 15-28 (28-day regimen). The primary end point was objective response rate (ORR). RESULTS: One hundred and twenty-three patients received ≥ 1 cycle of therapy (63, 21-day regimen; 60, 28-day regimen). ORRs were 13% [95% confidence interval (CI) 6%-24%] and 17% (95% CI 8%-29%), and disease control rates were 48% (95% CI 35%-61%) and 63% (95% CI 50%-75%) for the 21- and 28-day regimens, respectively. The median progression-free survival and overall survival were similar with both regimens. Both regimens were well tolerated with common grade ≥ 3 toxicities being neutropenia, asthenia/fatigue, and dyspnoea. Sequential administration of erlotinib did not interfere with the pharmacokinetic profile of eribulin. CONCLUSION: Intercalated combination of eribulin and erlotinib demonstrated modest activity and the addition of erlotinib did not appear to improve treatment outcome in an unselected population. The 28-day regimen is suitable for further investigation. Clinicaltrials.gov identifier: NCT01104155.

Phase II study of gemcitabine and cisplatin as first-line chemotherapy in inoperable biliary tract carcinoma.

OBJECTIVES: The prognosis for patients with unresectable biliary tract cancer is poor and existing chemotherapy is relatively ineffective. Therefore, a need exists for new, effective chemotherapeutic regimens. The aim of this study was to determine the efficacy and safety profile of gemcitabine plus cisplatin in patients with unresectable biliary tract cancer (cholangiocarcinoma) and gall bladder cancer. METHODS: From December 2000 to July 2002, 43 patients received gemcitabine 1250 mg/m(2) in a 30-min i.v. infusion on d1, 8 and cisplatin 75 mg/m(2) in a 2-h i.v. infusion on d1 (with appropriate hydration), every 3 weeks. ELIGIBILITY: Normal hematologic parameters and creatinine levels; serum bilirubin < 5 mg/dl. RESULTS: Forty-three patients enrolled; 40 were assessable (three patients were not assessable due to incomplete treatment; they chose to discontinue chemotherapy after the first cycle). There were 23 males and 17 females, median age 50 years (range 31-69), median Karnofsky PS 80%. Tumor types: cholangiocarcinoma (39), gall bladder cancer (1). Median number of chemotherapy courses was four (range 1-8). Overall response rate was 27.5% (PR in 11 pts), with 32.5% SD and/or minor response. Median survival time was 36 weeks. Grade 3 hematologic toxicity: anemia (4.33%), leukopenia (1.73%). Non-hematologic toxicity (i.e. rash, nausea, vomiting, neuropathy and myalgia) ranged from mild to moderate. CONCLUSIONS: Gemcitabine plus cisplatin is active in biliary tract carcinoma. These data warrant further investigation of single-agent gemcitabine versus gemcitabine plus cisplatin or its derivative, i.e. oxaliplatin.

Combination of gemcitabine and cisplatin in advanced non-small cell lung cancer.

A prospectively designed phase II study of non-small cell lung cancer stage IIIb and IV treated by gemcitabine and cisplatin was studied. The dosage of gemcitabine was 1 g/m2 weekly on day 1, 8 and 15. Cisplatin 100 mg/m2 was given on day 15 of each 28 day cycle. Twenty-eight patients were treated and all cases were evaluated for response. Survival and toxicity were determined in all enrolled patients. Thirteen (46.4%) achieved partial response (PR). By using Kaplan Meier's method the mean survival time was 19.8 months. One year survival was 66.6 per cent. Non hematologic toxicity consisted of mild nausea, vomiting, alopecia and hyperpigmentation of the skin. Rising creatinine of grade I was seen in 1.6 per cent. Anemia and leukopenia were common hematologic side effects with 27.5 per cent and 14.2 per cent of patients experiencing grade III and IV toxicity respectively. Both side effects were usually short lived and responsible for the delay of gemcitabine administration on day 8 and 15 in 18.3 per cent and 23.3 per cent on day 15 alone of chemotherapeutic courses respectively. We conclude that the combination of gemcitabine and cisplatin at this dosage achieved good response with moderate side effects.

Protective effects of fosfomycin on cisplatin-induced nephrotoxicity in patients with lung cancer.

SUBJECTS, MATERIAL AND METHODS: Protective effects of fosfomycin on cisplatin-induced nephrotoxicity have been previously reported, however, the proper time, duration and dosage of its administration were uncertain. Therefore, we investigated the protective effect of concurrent administration of twice-daily doses of 2 g fosfomycin for 5 days in 13 cisplatin-naïve lung cancer patients who were due to receive a single dose per cycle of 100 mg/m2 cisplatin. On each chemotherapeutic cycle, patients were randomly given cisplatin alone or cisplatin plus fosfomycin every 4 weeks for a maximum of 4 consecutive cycles. Indicators of nephrotoxicity, urinary N-acetyl-beta-D-glucosaminidase (NAG) activity, serum creatinine (Scr) and creatinine clearance (Clcr) were determined the day before and at day 3 and day 6 after cisplatin administration. Results were compared and statistically analyzed by the non-parametric Mann-Whitney's test. We found that the NAG activities obtained on day 0, day 3 and day 6 of the fosfomycin cycles were comparable to values obtained during the control cycles (p > 0.05). Moreover, the NAG activities on day 3 of both treatment cycles were significantly elevated from baseline (p < 0.01) and had normalized on day 6. There were no significant changes in serum creatinine and creatinine clearance. CONCLUSION: High-dose cisplatin induced reversible elevation of urinary NAG and concurrent administration of low-dose fosfomycin for 5 days had no effect on the enzymuria. In the prevention of cisplatin nephrotoxicity, a further study using dose escalation (8 to 12 g/d) of fosfomycin administered 2 to 3 days prior to cisplatin are required to demonstrate its nephroprotective effects.

Efficacy of UFT plus oral leucovorin in advanced colorectal cancer: a multicenter study.

PURPOSE: To evaluate the efficacy and toxicity of UFT plus oral leucovorin in advanced colorectal cancer. MATERIAL AND METHOD: Twenty cases of advanced colorectal cancer were entered into the study. All patients must have histologic proof and have measurable disease. Prior to the treatment all patients should have normal baseline hematology and normal liver and renal function, ECOG Performance status < or = 2 and age 18-75 years. Chemotherapeutic drugs consisted of UFT 350 mg/m2/day divided into 3 doses (8 hours apart) plus oral leucovorin 15 mg every 8 hours. Duration of treatment was 21 days per each cycle. Treatment was recycled every 28 days. RESULTS: Four cases (22.2%) had partial responses and six cases (33.3%) had stable disease. Duration of response was 4(+)-7+ months. Toxicity was darkened skin, mild diarrhea and mild alopecia. CONCLUSION: UFT plus oral leucovorin was one of the active regimens in the treatment of advanced colorectal cancer.

Phase II study of ifosfamide, carboplatin, etoposide and GM-CSF in small cell lung cancer.

UNLABELLED: Twenty patients with small cell lung cancer (SCLC) were entered to the study. Fourteen cases were male and six cases were female. Twelve cases were extensive disease, eight cases were limited disease. Median age was 60 years (range = 40-72 years), median performance status was 70 per cent (range = 60-80%). All patients were treated with combination chemotherapy consisting of ifosfamide 5 g/m2 intravenous infusion over 4 hours with mesna uroprotection, carboplatin 300 mg/m2 intravenous infusion over 2 hours on day 1, and etoposide 120 mg/m2 intravenous infusion over 4 hours on day 1-3. Chemotherapy was re-cycled every 28 days. Assessment of hematologic toxicity (CBC) was performed two times per week. If there was grade 3 or 4 neutropenia on any cycle of chemotherapy, GM-CSF was administered for febrile neutropenia and on the next cycle it was administered prophylactically on day 4-14. RESULTS: Seventeen cases were evaluable for response and toxicity (three cases were inevaluable due to loss to follow-up after the first cycle of chemotherapy). Fourteen cases (five limited disease, nine extensive disease) achieved partial response (82.5%). Two cases had stable disease, one case died on day 7. One year survival was 23.5 per cent. Seventy and a half percent grade 3 and 4 neutropenia was seen during the first cycle. One patient had febrile neutropenia. After being prophylactically treated with GM-CSF, grade 3 and 4 neutropenia was reduced from 70.5 per cent to 56.2 per cent, 46.7 per cent, 63.6 per cent, 42.8 per cent and 0 per cent in cycle 2-6 respectively. Major toxicity of GM-CSF consisted of transient chest distress, chills, sweating and hypotension which subsided in 5-10 minutes. No fever or skin rash was observed. CONCLUSION: Combination of ifosfamide, carboplatin and etoposide (ICE) is an active regimen for small cell lung cancer. However, because of its severe myelosuppression, this regimen needs hematopoietic growth factor support, and GM-CSF was used in this study. The administration of GM-CSF rendered ICE chemotherapy to be given safely.

Efficacy and tolerability of tropisetron in the prevention of cisplatin-induced nausea and vomiting in advanced non-small cell lung cancer.

The efficacy and tolerability of tropisetron were studied in an open trial comprising a total of 30 patients with advanced non-small cell lung cancer undergoing high-dose, cisplatin-based chemotherapy (cisplatin dosage 100 mg/m2). Patients received tropisetron 5 mg intravenous infusions for 15 min on day 1. followed by 5 mg tropisetron taken orally in the morning on days 2 6. All treated patients were assessed during the entire treatment period (6 days). Acute nausea and vomiting were evaluated during the 24 h after chemotherapy. Delayed nausea and vomiting were evaluated during days 2-6 after chemotherapy. Response to tropisetron was graded as: complete control, major control, minor control and failure for nausea or vomiting. Rates for complete plus major control of acute nausea and vomiting in cycles 1-5 were 77%, 81%, 86%, 67% and 75%, respectively. Rates for complete plus major control of delayed nausea and vomiting in cycles 1-5 were 87%, 76%, 86%, 78% and 75%, respectively. Adverse reactions were mainly headache and diarrhea, but both reactions were mild and are common in most patients treated with this type of antiemetic agent. It is concluded that tropisetron is an effective drug for the prevention of side effects of highly emetogenic drugs such as cisplatin. The dosage and schedule of tropisetron reported here can prevent both acute and delayed nausea and vomiting.

Relationship between quality of life and clinical outcomes in advanced non-small cell lung cancer: best supportive care (BSC) versus BSC plus chemotherapy.

In a prospective randomized study, 287 patients with advanced non-small cell lung cancer (NSCLC) stage IIIb or IV with ECOG performance status (PS) 0-1 or 2 were randomly assigned to receive either best supportive care (BSC) or supportive care plus combination chemotherapy (IEP regimen: ifosfamide 3 gm/m2 IV with mesna uroprotection, epirubicin 60 mg/m2 IV on day 1 and cisplatin 60 mg/m2 IV on day 2; or MVP regimen: mitomycin-C 8 mg/m2, cisplatin 100 mg/m2 IV on day 1, vinblastine 4 mg/m2 IV on days 1 and 15). Serial assessment of Karnofsky performance status (KPS), modified Functional Living Index-Cancer (T-FLIC) and modified Quality of Life-Index (T-QLI) were used to estimate the quality of life. Interviews were done at entry, at the third month and at 2 months post complete treatment. At least two courses of chemotherapy were considered to be adequate for response evaluation. Patients were treated for a total of four to six courses or until progression of disease. Partial response rates were 40 and 41.7% in IEP and MVP arms. Median survival durations were 5.9 and 8.1 months for the IEP and MVP chemotherapy arms, and 4.1 months for BSC (log-rank test: P = 0.0003). One year survival was 13, 29.8 and 39.3% for the BSC, IEP and MVP regimens, respectively. Two years survival was 7.8, 6.4 and 13.1% for the BSC, IEP and MVP regimens, respectively. Improvement in quality of life (QOL) scores at the first, second and third interview were seen in chemotherapy arms only, not in the BSC arm. We conclude that combination chemotherapy improves the quality of life as well as prolonging the survival of patients with advanced NSCLC.

Preliminary report of the Asian-Oceanian Clinical Oncology Association randomized trial comparing cisplatin and epirubicin followed by radiotherapy versus radiotherapy alone in the treatment of patients with locoregionally advanced nasopharyngeal carcinoma. Asian-Oceanian Clinical Oncology Association Nasopharynx Cancer Study Group.

BACKGROUND: The aim of this trial was to compare the outcome achieved with neoadjuvant chemotherapy followed by radiotherapy to that achieved with radiotherapy alone for patients with locoregionally advanced undifferentiated or poorly differentiated nasopharyngeal carcinoma (NPC) meeting one of the following criteria: Ho's T3 disease, Ho's N2-N3 disease, or lymph node size > or =3 cm. METHODS: Between September 1989 and August 1993, 334 patients were enrolled in the study, with equal numbers of patients randomized to the neoadjuvant chemotherapy arm (CT arm) and the radiotherapy arm (RT arm). Neoadjuvant chemotherapy consisting of 2-3 cycles of cisplatin (60 mg/m2 on Day 1) and epirubicin (110 mg/m2 on Day 1) followed by radiotherapy was given to the CT arm. For radiotherapy, a dose of 66-74 gray (Gy) (median, 71 Gy) was delivered to the primary tumor and 60-76 Gy (median, 66 Gy) to the neck. Two hundred eighty-six eligible patients completed the treatment and were evaluable for treatment response (134 in the CT arm, 152 in the RT arm). All patients were included in the survival analysis based on the intention to treat. The median follow-up was 30 months for the whole cohort and 41 months for the surviving patients. RESULTS: Analysis of the 334 patients based on the intention to treat showed no significant difference in relapse free survival (RFS) or overall survival (OS) between the 2 treatment arms (3-year RFS rate: 48% in the CT arm vs. 42% in the RT arm, P = 0.45; 3-year OS rate: 78% vs. 71%, P = 0.57). In an efficacy analysis based on only the 286 evaluable patients, a trend of improved RFS favoring the CT arm was observed (3-year RFS rate: 58% vs. 46%, P = 0.053), with again no significant difference in OS (3-year OS rate: 80% vs. 72%, P = 0.21). In the subgroup of 49 patients with bulky neck lymph nodes >6 cm, improved RFS (3-year RFS rate: 63% vs. 28%, P = 0.026) and OS (3-year OS rate: 73% vs. 37%, P = 0.057) were observed, favoring the CT arm. CONCLUSIONS: This multicenter randomized study did not demonstrate any benefit with the addition of cisplatin-epirubicin neoadjuvant chemotherapy for patients with locoregionally advanced nasopharyngeal carcinoma; therefore routine administration of neoadjuvant chemotherapy to this target group cannot be recommended. Although the overall incidence of recurrence was reduced with the addition of chemotherapy in the efficacy analysis, the overall survival was not affected. A more effective chemotherapy regimen, the selection of an appropriate target group, and the use of an alternative strategy for combining chemoradiotherapy should be explored in future trials.

Lung cancer and quality of life.

Quality of life (QOL) is frequently used as an endpoint of measurement in cancer treatment. Compared to other cancers, there are only a few reports of QOL in the treatment of lung cancer. Several QOL instruments have been developed and this paper reports experience with the functional Living-Index-Cancer and Quality of Life Index tools in Lung Cancer treatment, in a randomised controlled trial of chemotherapy.

Phase II study of paclitaxel (Taxol) and ifosfamide (Holoxan) in inoperable non-small-cell lung cancer.

A total of 27 patients with advanced previously untreated non-small-cell lung cancer were treated with paclitaxel and ifosfamide. The starting dose of paclitaxel was 175 mg/m2 given for 3 h by intravenous infusion on day 1. Ifosfamide 4 g/m2 was given for 4 h by intravenous infusion on day 2. Dosage of the two drugs was modified according to nadir white blood count after each cycle. Involved in the treatment were 17 males and 10 female patients. The median age was 61 years (range 47-71 years) and the median Karnofsky performance status was 70% (range 60-90%), 13 cases were stage IIIb and 14 cases were stage IV. One case was not evaluable due to lost follow-up after a single dose of chemotherapy. There were five cases not determined due to a timing error. Of 21 evaluable cases, eight achieved partial response (PR 38%, confidence interval 18.1-61.5%), seven achieved stable disease, two had a minor response. The median survival time of the whole group was 255 days (range from 38 to 567 days). The major toxicities were myalgia; arthralgia and neuropathies. Throughout the study, only three cases (15%) were treated at dose level 0. After the first cycle, 18 cases were treated at dose level 1, after a second cycle, 13 cases were treated at dose level 2. Three cases with grade 3 leukopenia were seen at dose level 0. At dose level 1, two cases had grade 3 leukopenia. At dose level 2, four episodes of grade 3 leukopenia were noted. It is concluded that paclitaxel can be combined safely with ifosfamide at these dosage levels. The response rates were comparable to the other chemotherapy combination in advanced non-small-cell lung cancer. The survival results were acceptable and comparable to the cisplatin-containing regimen. This study indicates that combinations of paclitaxel and/or ifosfamide with other agents, such as gemcitabine and vinorelbine, should be explored.

Preliminary study of efficacy of intravenous cisplatin plus oral etoposide in small cell lung cancer.

Twenty-three patients with small cell lung cancer were treated with combination chemotherapy consisting of Cisplatin at 100 mg/m2 given by 2 hours intravenous infusion on day 1 and oral etoposide 25 mg/caplet given twice a day for 21 days repeated every 28 days for 6 cycles. Of 23 cases, four cases were not evaluable due to early death (three of them died from febrile neutropenia). Median age of the patients was 59 years (range = 45-76 years). Five cases were female and eighteen cases were male. Median Karnofsky performance status was 70 per cent (range = 50-90%). Five cases were extensive disease and eighteen cases were limited disease. Of 5 extensive disease cases, 1 complete response (20%) and 3 partial responses (60%) were achieved. Of 14 limited disease patients, 1 complete response (7.1%) and 11 partial responses (78.6%) were achieved. Hematologic toxicities were severe causing three patients to die because of febrile neutropenia, nine cases (10.7%) had grade 3 and 4 neutropenia. Grade 3 and 4 anemia and thrombocytopenia were seen in 28.6 per cent and 8.3 per cent respectively. Median survival time of all cases was 7 months. Thus, the combination of intravenous cisplatin and prolonged administration of oral etoposide could be administered to small cell lung cancer patients with high response rate, however, because of its severe toxicities, special caution should be considered and the optimal duration of oral etoposide should be evaluated.

Usefulness of the Thai modified functional living index--cancer (T-FLIC) and the Thai modified quality of life index (T-QLI) for advanced non-small cell lung cancer.

Serial assessment of Karnofsky performance status (KPS), the Thai modified Functional Living Index Cancer (T-FLIC) and the Thai modified Quality of Life Index (T-QLI) have been used to estimate the quality of life of advanced non-small cell lung cancer patients. This is a prospective randomized trial of best supportive care (BSC) versus best supportive care plus combination chemotherapy given to patients with Stage III b or IV, ECOG 0-1 or 2. There was a good correlation between Karnofsky performance status (KPS) and T-FLIC scores, between T-FLIC and T-QLI scores as the study began. Thus the T-FLIC and T-QLI were useful instruments for the quality of life assessment in Thai patients.

Ifosfamide, epirubicin and cisplatin (IEP): another active combination for small cell lung cancer (SCLC).

Sixty-four SCLC patients (44 males and 20 females, median age 60 years, median PS 60%) were treated with an IEP regimen. Forty-nine cases were evaluable, 35 cases were limited disease (LD) and 14 cases were extensive disease (ED). Treatment consisted of ifosfamide 1.5 g/m2 i.v. infusion for 4 h on days 1 and 2 with mesna uroprotection; epirubicin 60 mg/m2 i.v. on day 1; and cis-platin 60 mg/m2 i.v. infusion over 2 h on day 3; repeated treatment every 4 weeks. Eighty percent response rate (95% confidence limit = 66.75% to 93.25%) was seen in LD with 22.8% CR. In ED, total response rate was 85.7% (95% confidence limit = 67.36% to 104.04%) with 21.4% CR. One-year survival of LD was 45.5% and ED was 17.6%. Treatment toxicity was moderate. Most common toxic effects included alopecia, leukopenia (28.5% grade 3, 14.3% grade 4) nausea and vomiting (50% grade 2, 15% grade 3) and anemia (26.5% grade 3 and 4). Addition of thoracic radiotherapy after complete chemotherapy (only CR and PR in LD cases) was a good prognostic factor. These results suggest that IEP regimen is one of the active combination for SCLC. The dosage of IEP in this study caused moderate toxicity.

Analysis of the four combination chemotherapies in non-small cell lung cancer treated at Maharaj Nakorn Chiang Mai Hospital.

From 1984 to 1991, patients with inoperable non-small cell lung cancer (NSCLC) were assigned to receive one of the four combination chemotherapies: 1. etoposide and cisplatin (P/VP-16), 2. vinblastine and cisplatin (P/V1b), 3. ifosfamide, epirubicin and cisplatin (IEP), 4. mitomycin, vinblastine and cisplatin (MVP). This study was not a randomized study, but it was a series of Phase II trials. The response rates were 11/29 (48.2%), 3/22 (13.6%), 18/40 (45%), 12/37 (32.4%), respectively. The response rate was significantly lower with the P/V1b regimen than with the P/VP-16, IEP or MVP (p = 0.04). The median survival times of responders were P/VP-16 11 months, IEP 12.4 months. Median survival time of MVP was 7+ months. For P/V1b survival time was not evaluated due to effect of secondary treatment. Since the response rate and survival duration of NSCLC patients treated with either one of these regimens were similar, the difference in view of drug toxicities and quality of life should be the most important issue concerning the selection of drug regimens in NSCLC.
