Impact of pretreatment factors on adverse events: a pooled analysis of North Central Cancer Treatment Group advanced stage non-small cell lung cancer trials.

Introduction: This pooled analysis was performed to examine the impact of pretreatment factors on severe (grade 3 or higher) adverse events (AE) in patients with advanced stage non-small cell lung cancer (NSCLC).

Methods: A pooled data set of 1053 participants from nine North Central Cancer Treatment Group clinical trials was used. Age, gender, performance status, tumor stage, body mass index, serum creatinine levels, hemoglobin levels, white blood cell counts, and platelet counts were evaluated univariately and multivariately using logistic regression.

Interleukin-1 genetic polymorphisms and their relationship to the cancer anorexia/weight loss syndrome in metastatic gastric and gastroesophageal junction adenocarcinoma.

Interleukin-1 (IL-1) beta is a putative mediator of the cancer anorexia/weight loss syndrome, and certain polymorphisms of its gene are thought to be associated with a greater risk of gastric cancer. Do these IL-1 beta genetic polymorphisms predispose patients with gastric and gastroesophageal cancer to the anorexia/weight loss syndrome? This study focused on 44 patients with metastatic gastric and gastroesophageal cancer. All underwent genotyping, completed serial quality-of-life questionnaires germane to appetite, and underwent meticulous serial follow-up.

A prognostic model for advanced stage nonsmall cell lung cancer. Pooled analysis of North Central Cancer Treatment Group trials.

Background: A pooled analysis was performed to examine the impact of pretreatment factors on overall survival (OS) and time to progression (TTP) in patients with advanced-stage nonsmall cell lung cancer (NSCLC) and to construct a prediction equation for OS using pretreatment factors.

Methods: A pooled data set of 1053 patients from 9 North Central Cancer Treatment Group trials was used. Age, gender, Eastern Cooperative Oncology Group performance status (PS), tumor stage (Stage IIIB vs.

Phase II NCCTG trial of oral topotecan and paclitaxel with G-CSF (filgrastim) support in patients with previously untreated extensive-stage small cell lung cancer.

Objective: To determine the efficacy and toxicity of oral topotecan and paclitaxel in untreated patients with extensive stage small cell lung cancer (SCLC).

Patients And Methods: Thirty-eight patients received 1.75 mg/m2 of oral topotecan days 1 to 5 and 175 mg/m2 paclitaxel IV over 3 hours on day 5 (after topotecan) every 4 weeks for 6 cycles.

Randomized trial of tamoxifen alone or combined with fluoxymesterone as adjuvant therapy in postmenopausal women with resected estrogen receptor positive breast cancer. North Central Cancer Treatment Group Trial 89-30-52.

Purpose: This clinical trial evaluated the addition of fluoxymesterone (Flu) to tamoxifen (Tam) in women with resected early stage breast cancer and attempted to corroborate the findings of superiority for the combination over Tam alone seen in a previous randomized trial in metastatic disease.

Patients And Methods: Postmenopausal women with early stage breast cancer that was known to be estrogen receptor (ER) positive were randomized to treatment with Tam (20 mg per day orally for 5 years) alone or combined with Flu (10 mg orally twice per day for 1 year). The primary endpoint was relapse-free survival (RFS) defined as local-regional or distant recurrence including ductal carcinoma in situ of the ipsilateral, but not contralateral breast, and death from any cause.

Phase II trial of oral vinorelbine for the treatment of metastatic breast cancer in patients > or = 65 years of age: an NCCTG study.

Background: A one-stage phase II trial was conducted to assess the tumor response rate and toxicity profile of single agent oral vinorelbine as first or second-line chemotherapy for women at least 65 years of age with metastatic breast cancer.

Patients And Methods: Twenty-five patients with metastatic breast cancer aged > or = 65 years of age were enrolled to receive oral vinorelbine on a weekly basis. The oral vinorelbine was given at 60 mg/m2 weekly for the first four doses and was increased to 70 mg/m2 for the subsequent administrations if there was no grade 4 neutropenia or no more than one episode of grade 3 neutropenia.

Phase III comparison of depomedroxyprogesterone acetate to venlafaxine for managing hot flashes: North Central Cancer Treatment Group Trial N99C7.

Purpose: Vasomotor hot flashes are a common problem in menopausal women. Given concerns regarding estrogen and/or combined hormonal therapy, other treatment options are desired. Prior trials have confirmed that progestational agents and newer antidepressants effectively reduce hot flashes.

Docetaxel and capecitabine in patients with metastatic adenocarcinoma of the stomach and gastroesophageal junction: a phase II study from the North Central Cancer Treatment Group.

Background: Previous studies suggest that the combination of docetaxel and capecitabine are worthy of further testing in patients with metastatic adenocarcinoma of the stomach and gastroesophageal junction. We therefore undertook this phase II study to test this combination in a multi-institutional, first-line clinical trial.

Patients And Methods: Forty-four eligible patients with histologic or cytologic confirmation of the above malignancy were recruited.

Two concurrent phase II trials of paclitaxel/carboplatin/trastuzumab (weekly or every-3-week schedule) as first-line therapy in women with HER2-overexpressing metastatic breast cancer: NCCTG study 983252.

Purpose: The efficacy and tolerability of 2 different schedules of paclitaxel/carboplatin/trastuzumab for HER2-overexpressing metastatic breast cancer (MBC) were evaluated in this parallel multicenter phase II trial.

Patients And Methods: Patients received every-3-week therapy (n = 43) consisting of a 200 mg/m(2) dose of paclitaxel/carboplatin area under the curve (AUC) of 6 mg/mL per minute and trastuzumab (an initial 8 mg/kg dose and subsequent 6 mg/kg doses) administered every 21 days for 8 cycles or weekly therapy (n = 48) consisting of an 80-mg/m(2) dose of paclitaxel/carboplatin AUC of 2 mg/mL per minute for 3 of 4 weeks, with weekly trastuzumab (an initial 4-mg/kg dose and subsequent 2-mg/kg doses) administered every 4 weeks for 6 cycles. Trastuzumab was continued until disease progression or unacceptable toxicity.

A phase II trial of docetaxel and carboplatin as first-line chemotherapy for metastatic breast cancer: NCCTG study N9932.

Objective: A phase II multi-institutional clinical trial conducted to evaluate the efficacy and tolerability of docetaxel and carboplatin as first-line therapy for women with metastatic breast cancer.

Methods: Patients had histologically confirmed metastatic breast cancer with at least one measurable lesion. Prior adjuvant chemotherapy was permitted, provided that at least 12 months had elapsed between any prior taxane and platinum therapy.

Phase II/III study of doxorubicin with fluorouracil compared with streptozocin with fluorouracil or dacarbazine in the treatment of advanced carcinoid tumors: Eastern Cooperative Oncology Group Study E1281.

Purpose: Optimal treatments for metastatic carcinoid tumor remain undefined, and the role of chemotherapy for symptomatic patients with progressive disease is uncertain.

Patients And Methods: Two hundred forty-nine patients with advanced carcinoid tumors were randomized to either doxorubicin with fluorouracil (FU/DOX) or streptozocin with fluorouracil (FU/STZ). Patients crossed over to the dacarbazine (DTIC) treatment after disease progression following first-line treatment (either FU/DOX or FU/STZ), and 73 patients were assigned to one of these three treatments based on their previous treatment or on abnormal baseline cardiac or renal function.

Results of combined-modality therapy for limited-stage small cell lung carcinoma in the elderly.

Background: A Phase III trial was conducted by the North Central Cancer Treatment Group to determine whether chemotherapy (etoposide and cisplatin) plus either twice-daily radiotherapy (BIDRT) or once-daily radiotherapy (QDRT) resulted in a better outcome for patients with limited-stage small cell lung carcinoma (LD-SCLC). No difference in survival was identified between the two arms. The current analysis examined the relation between age and outcome for patients treated during this trial.

Phase II study of gemcitabine plus cisplatin in patients with metastatic breast cancer: a North Central Cancer Treatment Group Trial.

Background: This 2-stage, phase II cooperative group trial examined the efficacy and toxicity of 1000 mg/m2 gemcitabine plus 25 mg/m2 cisplatin weekly for 3 weeks and repeated every 28 days for patients with previously treated metastatic breast cancer.

Methods: Eligible patients had to have measurable metastatic disease. Progression on prior treatment with at least 1 chemotherapy program for metastatic disease and 1 prior anthracycline and/or taxane-containing regimen in either the metastatic or adjuvant setting was required.

Investigating four 'myths' surrounding dysphagia in patients with metastatic esophageal cancer. A multi-institutional study from the North Central Cancer Treatment Group.

Eighty-five to 95% of esophageal cancer patients suffer dysphagia. Yet, few studies have focused on this symptom, and four 'myths' persist: (i) dysphagia cannot be measured; (ii) chemotherapy cannot palliate it; (iii) dysphagia predicts a poor prognosis; (iv) dysphagia is associated with a frustratingly insatiable appetite. Forty-four patients with metastatic esophageal cancer participated in this quality of life/translational component of a previously reported clinical trial.

Mortality associated with daily bolus 5-fluorouracil/leucovorin administered in combination with either irinotecan or oxaliplatin: results from Intergroup Trial N9741.

Background: Intergroup Trial N9741 evaluated 5-fluorouracil (5-FU)/leucovorin (LV) administered in conjunction with either irinotecan or oxaliplatin in the first-line treatment of advanced colorectal carcinoma (CRC). The current report describes two treatment arms that were withdrawn from the protocol due to unexpected treatment-related toxicities and a high mortality rate. The complications observed in these arms highlight the importance of aggressive and immediate supportive care in the management of digestive toxicity.

Phase III, randomized, double-blind study of epoetin alfa compared with placebo in anemic patients receiving chemotherapy.

Purpose: To determine whether weekly epoetin alfa could improve hemoglobin (HgB) levels, reduce RBC transfusions, and improve quality of life (QOL) in patients with advanced cancer and with anemia after receiving myelosuppressive chemotherapy.

Patients And Methods: This double-blind, placebo-controlled study randomly assigned patients to placebo or epoetin alfa (Ortho Biotech, Bridgewater, NJ) 40,000 U subcutaneous weekly for 16 weeks. QOL, HgB, and RBC transfusions were measured pretreatment and monthly.

Investigating the utility of serum cytokine measurements in a multi-institutional cancer anorexia/weight loss trial.

Background: Interleukin-1 beta (IL-1beta), tumor necrosis factor alpha (TNFalpha), and interleukin-6 (IL-6) have been implicated in the cancer anorexia/weight loss syndrome. However, previous smaller studies have yielded conflicting results as to whether circulating, serum concentrations of these cytokines are in fact elevated. As the translational component of a large multi-institutional trial, this study assessed the clinical value of serum concentrations of these cytokines in patients with this syndrome.

Randomized phase II study of two irinotecan schedules for patients with metastatic breast cancer refractory to an anthracycline, a taxane, or both.

Purpose: A pressing need exists for agents active against anthracycline- or taxane-refractory metastatic breast cancer (MBC), or both. Previous clinical trials suggested that irinotecan might have such activity. We conducted this multicenter phase II study to assess efficacy and tolerability of two irinotecan schedules.

Phase III study of adjuvant chemotherapy and radiation therapy compared with chemotherapy alone in the surgical adjuvant treatment of colon cancer: results of intergroup protocol 0130.

Purpose: Some patients with colon cancer have a high risk of local recurrence postoperatively. This trial was undertaken to determine whether radiation therapy added to an adjuvant chemotherapy regimen improves outcome in high-risk patients.

Patients And Methods: Patients with resected colon cancer with tumor adherence or invasion of surrounding structures, or with T3N1 or T3N2 tumors of the ascending or descending colon were randomly assigned to receive fluorouracil and levamisole therapy with or without radiation therapy.

Long-term results of a phase III trial comparing once-daily radiotherapy with twice-daily radiotherapy in limited-stage small-cell lung cancer.

Purpose: This Phase III study was performed to determine whether twice-daily (b.i.d.

An eicosapentaenoic acid supplement versus megestrol acetate versus both for patients with cancer-associated wasting: a North Central Cancer Treatment Group and National Cancer Institute of Canada collaborative effort.

Purpose: Studies suggest eicosapentaenoic acid (EPA), an omega-3 fatty acid, augments weight, appetite, and survival in cancer-associated wasting. This study determined whether an EPA supplement-administered alone or with megestrol acetate (MA)-was more effective than MA.

Patients And Methods: Four hundred twenty-one assessable patients with cancer-associated wasting were randomly assigned to an EPA supplement 1.

Weekly carboplatin and paclitaxel in elderly non-small-cell lung cancer patients (>or=65 years of age): a phase II North Central Cancer Treatment Group study.

The purpose of this study was to determine the tumor response rate and toxicity profile of low-dose weekly carboplatin and paclitaxel in advanced non-small-cell lung cancer (SCLC) patients 65 or more years of age. Forty-nine patients 65 years of age or more with advanced non-SCLC with a median age of 73 years (range: 65-85) and an Eastern Cooperative Oncology Group performance status of 0, 1, or 2 in 31%, 47%, and 22% of patients, respectively, were treated and evaluated. Patients received carboplatin (AUC = 2) and paclitaxel 50 mg/m2 on days 1, 8, and 15 of a 4-week cycle.

Daily activities: exploring their spectrum and prognostic impact in older, chemotherapy-treated lung cancer patients.

Background: Performance scores predict benefits and toxicities from chemotherapy. Among older cancer patients, however, many investigators have empirically called for a detailed assessment of activities of daily living, claiming that the utility of performance scores is limited in this older population. This study's goals were therefore twofold: (1).

A phase II study of the dolastatin 15 analogue LU 103793 in the treatment of advanced non-small-cell lung cancer.

A phase II study of the dolastatin 15 analog LU 103793 was conducted by the North Central Cancer Treatment Group in patients with advanced non-small-cell lung cancer (SCLC). Previously untreated patients received this agent at a dosage of 2.5 mg/m2 as a 5-minute intravenous infusion for 5 consecutive days every 3 weeks.
