Is there hope?

My mother was diagnosed almost a year ago. At the time we were hopeful and looking at atleast 5 years. Since then she has tried 3 types of chemotherapies (3 cycles of each so total 9 cycles) none of them have had any effect and the disease has progressed. The last chemotherapy was even done after doing extra tests for drug sensitivity and gene mutations. In between we’ve taken mutiple second opinions all agreeing on the line of treatment. We are now trying oral form of chemotherapy which the doctor says will be the last option to try. So far we’ve tried folforinox, gemcitabin +nab ac and gemcitabin + cisplastin . As of last pet scan - multiple lesions in liver, largest one measures 8.3 x 10.3 cm , pancreatic lesion is lesion (TRA) 4.2 x(AP) 3.5 x (CC) 3.4 cm

One specialist recommended we can try immunotherapy-Keytruda (pembrolizumab)but in my country it’s not covered under insurance and we will have to take a huge loan to afford.

The doctor say if this chemotherapy doesn’t work she’s looking at less than 6 months. Would appreciate any advice please .
