A Bayesian re-assessment of two Phase II trials of gemcitabine in metastatic nasopharyngeal cancer

Phase II trials of second-line intraperitoneal (IP) cisplatin-based therapy in patients with ovarian cancer have demonstrated the ability of this approach to produce objective antitumor responses, including surgically defined complete responses (CRs), in individuals with persistent small-volume disease after front-line cisplatin-based intravenous (IV) treatment. To examine the influence of a prior response to systemic cisplatin on the activity of second-line IP cisplatin, we retrospectively analyzed two phase II trials of cisplatin-based IP therapy in persistent/recurrent ovarian cancer conducted at our institution. Of the 89 assessable patients on the two trials, 52 (58%) had previously responded to IV cisplatin. The overall response and CR rates to second-line IP cisplatin-based therapy in this previously responding population were 56% and 33%, respectively, compared with overall response and CR rates in the 37 nonresponders to IV cisplatin of 11% and 3%, respectively (P less than .001; chi 2, 1 df). In the 36 patients responding to systemic cisplatin and whose largest tumor mass measured less than 1 cm at IP cisplatin initiation, a 42% CR rate was observed, compared with a 7% CR rate in the 14 patients with the same bulk of disease who had previously failed to respond to systemic cisplatin (P less than .025). We conclude that a prior response to systemic cisplatin strongly influences the antineoplastic activity of second-line IP cisplatin in ovarian cancer.

10520 Background: DFSP is an infiltrative, low-grade, dermal tumor with propensity to recur locally and occasionally metastasize. Translocation between COL1A1 on chromosome 17 and PDGFB on chromosome 22, which results in transcriptional upregulation of PDGFB, is characteristic of DFSP. Autocrine/paracrine PDGFB-mediated activation of PDGFRB drives DFSP proliferation. Two distinct phase II trials of imatinib in patients (pts) with locally advanced or metastatic DFSP were conducted, 1 in North America (SWOG) with confirmed objective response rate and 1 in Europe (EORTC) with 14 week progression-free rate as primary end-points. Methods: Pts with locally advanced or metastatic DFSP were eligible. In the EORTC trial confirmation of t(17;22) by FISH was prospectively required for participation, imatinib was started at 400mg bid, surgery was undertaken after 14 weeks if feasible and response was assessed at 14 weeks. Full accrual was to be 44 pts in one step. In the SWOG trial confirmation of t(17;22) by RT-PCR was performed after enrollment, imatinib was started at 400mg daily and response was assessed every 8 weeks. Full accrual was to be 40 pts in 2 steps. Results: 16 pts were enrolled in EORTC and 8 pts enrolled in SWOG trial. The studies were closed early because of slow accrual and regulatory approval of imatinib in DFSP. Pts age ranged from 24 to 70 yrs, DFSP was located on head/neck, trunk and extremity in 7, 11 and 6 pts, respectively, ranged in size from 1.2–49 cm and was classic, pigmented and fibrosarcomatous DFSP in 13, 1 and 7 pts, respectively. One patient did not have DFSP on central review, lacked t(17;22) and thus was ineligible. Metastases were present in 7 pts involving lung in 6 pts. 11 pts (46%) had partial response, 9 pts had stable disease and 4 pts had progressive disease as best response. Median time to progression was 1.7 yrs. Response and progression-free at 1 yr rates were similar between studies. Imatinib was stopped in 11 pts for progression, 1 pt for toxicity, 2 pts resected free of gross disease and 1 pt withdrew. Conclusions: Imatinib is active in DFSP harboring t(17;22) with an objective response rate approaching 50% and is active in fibrosarcomatous DFSP. Response rates and time to progression did not appear to differ between pts taking 400 mg daily versus 400 mg bid. [Table: see text]

4109 Background: Retrospective data in some cancer types suggested a possible different toxicity profile with chemotherapy and targeted therapies according to gender. However, data from prospective studies are still very limited, especially in infrequent tumors such as NETs. Methods: Pts with advanced pancreatic and gastrointestinal NETs treated with pazopanib or lenvatinib in the multicenter open-label phase II studies PAZONET and TALENT respectively, were included in the analysis. Both studies were performed by Spanish Task Force Group for Neuroendocrine Tumors (GETNE). All toxicity grades with an incidence higher than 5% were considered for univariate review. Additionally, all grade 3-4 toxicities were analyzed separately. Results: 155 pts (47.7% female) with 1213 adverse events (AEs) (20% G3-4) divided in 121 categories were included. In female patients, liver toxicity, headache, pyrexia, nausea/vomiting, hair/skin disorders and dizziness were significantly more common (table). The only toxicity with higher incidence in men was dysphonia (OR 0.42, 95% CI 0.2-0.9, p 0.02). There were no gender differences in grade 3-4 toxicities. Conclusions: We observed significant differences in toxicity AEs by gender in two prospective phase II studies with MKIs in NETs patients. Potential different approach to manage toxicity may be adopted based on gender. [Table: see text]
