Their prospective database was retrospectively reviewed for patients who were not candidates for primary Sepantronium Bromide solubility dmso Surgery and treated with preoperative chemoradiation strategies. Among this cohort of patients who received neoadjuvant therapy were 84 patients with anatomically borderline resectable disease. After preop CRT, 32 patients underwent surgical resection (31 R0/1 R1). Median survival in resected patients was 40 months compared to 15 months for unresected

patients. A small experience of only 13 patients with radiographic borderline resectable disease was reported by Brown et al. from Fox Chase Cancer Center (20). Treatment regimens included 50.4 Gy EBRT with either gemcitabine or 5FU-based concurrent Inhibitors,research,lifescience,medical chemotherapy followed by a median of 3 cycles of full dose chemotherapy, which was typically gemcitabine-based. Surgery was then performed at a median of 8 months from diagnosis. Of the 13 patients treated with neoadjuvant therapy and surgery, 8 patients Inhibitors,research,lifescience,medical were alive without disease at 24 months follow-up. Recently, Barugola and colleagues from Italy compared the outcomes of 41 patients diagnosed with unresectable or borderline resectable pancreatic cancer and who were treated either with neoadjuvant chemotherapy alone or with chemoradiation followed by successful surgical resection to 362 resectable patients treated with Inhibitors,research,lifescience,medical upfront surgery (21). There was no increase in operative morbidity

Inhibitors,research,lifescience,medical or mortality. Compared to patients receiving neoadjuvant chemotherapy alone, neoadjuvant chemoradiation significantly improved both the rate of pathologic complete response (0% vs. 12.5%; P=0.03%) and the rate of R0 resection (35% vs. 96%; P<0.001). No statistically significant difference in OS survival was observed between the patients who received neoadjuvant therapy group and those treated with upfront surgical resection (median survival 35 vs. 27 months; P=0.74). Therefore, despite imaging suggestive of greater local disease, neoadjuvant

chemoradiation could be successfully combined with surgical resection to achieve Inhibitors,research,lifescience,medical equivalent results as primary surgery. Current series For select patients with borderline resectable or locally unresectable pancreas cancer, we have used only the sequence of preoperative CRT followed by restaging, surgical exploration with resection/IOERT, as indicated. Of the 48 patients who received preop CRT, 31 proceeded to surgical exploration, Florfenicol and an R0/R1 resection was achieved in 16 patients. IOERT was included in the treatment for 28 of the 31 resected patients. Extent of surgical resection was the most important factor impacting survival with a 3-year OS of 36% after R0/R1 resection (Figure 1B). Despite the use of IOERT in the setting of unresectable disease, no patients were alive at 3 years after R2 resection or with unresectable disease. These findings are consistent with other studies in the literature described above.
