Abstract BACKGROUND: There is increasing evidence that paclitaxel and carboplatin are clinically active in the treatment of metastatic melanoma (MM). ABI‐007 an albumin‐bound formulation has demonstrated single‐agent activity against melanoma. METHODS: A parallel phase II trial was conducted patients with unresectable stage IV who were either chemotherapy naive (CN) or previously treated (PT). The regimen consisted (100 mg/m 2 ) area under curve (AUC2) administered on days 1, 8, 15 every 28...

Chemotherapy-induced peripheral neuropathy (CIPN) is a significant side effect of taxane and platinum-based chemotherapy. Several studies have supported the potential benefit glutathione for prevention platinum-induced CIPN. The current trial was designed to determine whether would prevent CIPN as result carboplatin/paclitaxel therapy.In total, 185 patients who received treatment with paclitaxel carboplatin were accrued between December 4, 2009 19, 2011. Patients randomized receive either...

The Oncotype DX colon cancer assay is a clinically validated predictor of recurrence risk in stage II patients. This prospective study evaluated the impact score (RS) results on physician recommendations regarding adjuvant chemotherapy T3, mismatch repair-proficient (MMR-P) Patients and Methods. Stage IIA patients were enrolled 17 centers. Patient tumor specimens assessed by RS test (quantitative reverse transcription-polymerase chain reaction) repair (immunohistochemistry). For each...

Gemcitabine, oxaliplatin and 5-fluorouracil (5-FU) are active in biliary tract cancer have a potentially synergistic mode of action non-overlapping toxicity. The objective these trials was to determine response, survival toxicity separately patients with bile duct (BDC) gallbladder (GBC) treated gemcitabine/oxaliplatin/5-FU chemotherapy. Eligible histologically proven, advanced or metastatic BDC (n=37) GBC (n=35) were gemcitabine (900 mg m−2 over 30 min), (65 m−2) 5-FU (1500 24 h) on days 1...

PURPOSE NCI-MATCH is a precision medicine trial using genomic testing to allocate patients with advanced malignancies targeted treatment subprotocols. This report combines two subprotocols evaluating trametinib, MEK1/2 inhibitor, in Neurofibromatosis 1 ( NF1[S1] or GNA11/Q [S2]) altered tumors. METHODS Eligible had tumors deleterious inactivating NF1 mutations by the customized Oncomine AmpliSeq panel. Prior MEK inhibitor was excluded. Glioblastomas (GBMs) were permitted, including...

Prior economic analysis that compared the 12-gene assay to published patterns of care predicted would improve outcomes while lowering medical costs for stage II, T3, mismatch-repair-proficient (MMR-P) colon cancer patients. This study assessed validity those findings with real-world adjuvant chemotherapy (aCT) recommendations from US third-party payer perspective.

Despite this approach the rate of recurrence remains high. Given difficulties postoperative therapy, efficacy extended therapy was assessed. Methods: Eligibility criteria included T3-4,N0 – T any ,N(+) disease amenable to radiation and surgery. Pts were randomized either arm A (docetaxel 60 mg/m 2 day 1 , oxaliplatin...

Metastatic carcinoma of unknown primary (CUP) has a very poor prognosis, and no standard first-line therapy currently exists. Here, we report the results phase II study utilizing combination gemcitabine irinotecan as therapy. Treatment was with 1000 mg/m(2) 75 weekly times four on six week cycle (Cohort I). Due to excessive toxicity, dose schedule were modified follows: 750 given three II). The endpoint confirmed response rate (CR + PR). Secondary endpoints consisted adverse events based...

How do oncologists choose therapy for the elderly? Oncologists assigned patients aged 65 years or older with incurable non-small cell lung cancer to: (a) carboplatin (AUC = 2) + paclitaxel 50 mg/m2 days 1, 8, 15 (28-day cycle × 4) followed by gefitinib; (b) gefitinib 250 mg/day. With (a), 12 of 34 were progression-free at 6 months; median time to progression was 3.9 months. (b), same occurred in 11 28 latter being 4.9 The most common reason conventional chemotherapy oncologists’ opinion that...
