I suggest a good dose of reality instead of meaningless platitudes. The 5 year survival rate is less than 30% for Duodenal Cancer. A stomach resection and chemotherapy can help extend her life, but the odds of remission are slim to none.
"Duodenal cancer was previously viewed as a rare type of cancer. Because of the rarity of this cancer, there are few reports on chemotherapy for duodenal cancer. The 5-year survival rate of duodenal cancer is reported to be less than 30% [1, 2]. On the other hand, it is reported that resection improves 5-year survival. When the tumor is resectable, pancreatoduodenostomy is the most common operative procedure, as the majority of tumors originate in the periampullary region.
Although cases of duodenal cancer treated with relatively noninvasive methods such as endoscopic treatment have been reported, the usefulness of chemotherapy has been reported to be low in cases of inoperable duodenal cancer, and no standard method of treatment has been established for this type of duodenal cancer. However, the establishment of a standard treatment is important because reports on this cancer have recently been increasing following improvement in the diagnosis using procedures such as computed tomography (CT), magnetic resonance imaging and endoscopy including endoscopic ultrasonography, capsule endoscopy and double balloon endoscopy.
S-1 is an oral anti-cancer agent, composed of tegafur, 5-chloro-2,4-dihydroxypyridine, and potassium oxonate, at a molar ratio of 1:0.4:1 . It is based on the biochemical modulation of 5-fluorouracil and reported to be effective in patients with advanced gastrocolorectal cancer [4, 5, 6]. We recently encountered a case of inoperable duodenal cancer where long-term survival for 6 years and 1 month was achieved by multidisciplinary treatment such as the chemotherapy mainly using S-1."
