The efficacy of TS-1?
Hello, Doctor.
My father has been diagnosed with stage IIA pancreatic cancer and has undergone a Whipple resection to remove the head of the pancreas, duodenum, and gallbladder.
The attending physician plans to use oral TS-1 for adjuvant therapy.
I would like to know if TS-1, which is used for advanced pancreatic cancer patients who are not surgical candidates, has any significant impact on the recurrence rate and survival rate for stage IIA patients.
Therefore, I would like to understand if this treatment is necessary.
Thank you for your clarification.

Hello, netizen:
1.
TS-1 as adjuvant therapy after pancreatic cancer surgery has shown a clinical treatment effect compared to the commonly used first-line chemotherapy drug (Gemcitabine), with a 5-year survival rate increase of approximately 20%.
2.
Overall, TS-1 may be beneficial for your father's survival rate; however, the clinical use of the medication should consider the pros and cons (Pros: longer survival; Cons: side effects such as gastrointestinal discomfort, diarrhea, oral mucositis, etc.).
It is recommended that you discuss this further with the attending physician!

More Info
The use of TS-1 (Tegafur, Gimeracil, and Oteracil Potassium) in the treatment of Stage II A pancreatic cancer, particularly after surgical resection such as the Whipple procedure, has garnered attention in recent years. Your father's situation, having undergone surgery to remove the head of the pancreas, duodenum, and gallbladder, places him in a category where adjuvant therapy is often considered to reduce the risk of recurrence and improve overall survival rates.
Clinical studies have shown that TS-1 can be beneficial for patients with pancreatic cancer. While it is more commonly associated with advanced stages of the disease, its application in the adjuvant setting (post-surgery) has been explored. Research indicates that TS-1 may improve the five-year survival rate by approximately 20% when compared to standard treatments like Gemcitabine alone. This suggests that TS-1 can indeed have a positive impact on survival rates for patients who have undergone surgical resection for pancreatic cancer.
However, the decision to use TS-1 should be made after careful consideration of the potential benefits and risks. The advantages include the possibility of prolonging survival and reducing the likelihood of cancer recurrence. On the other hand, TS-1, like any chemotherapy, can have side effects, which may include gastrointestinal issues such as nausea, diarrhea, and oral mucositis. These side effects can affect the patient's quality of life, particularly in older adults or those with pre-existing health conditions.
It is also important to note that the effectiveness of TS-1 can vary based on individual patient factors, including overall health, age, and the specific characteristics of the cancer. Therefore, it is crucial to have a thorough discussion with your father's oncologist about the appropriateness of TS-1 in his case. The oncologist can provide insights based on the latest research, your father's health status, and any other treatments that may be available.
In summary, TS-1 can potentially offer significant benefits for Stage II A pancreatic cancer patients post-surgery, particularly in terms of reducing recurrence rates and improving survival. However, the decision to proceed with this treatment should be individualized, taking into account the patient's overall health, potential side effects, and the specific clinical context. Engaging in an open dialogue with the treating physician will help ensure that the best possible treatment plan is developed for your father.
