Hepatobiliary and Pancreatic Cancers

We have been tracking this case for a year and discovered a new approach to combat pancreatic cancer

时间:2026-04-27 人气:
For cancer treatment, if the ultimate goal is to treat it as a "chronic disease," then it is crucial to follow up with patients at regular intervals.
The biggest characteristic of immunotherapy is to press the "pause button" on cancer. Therefore, for patients undergoing NKT cell therapy, we will also regularly present a case to update everyone on their progress.

Today, we will present a case of pancreatic cancer to you. Mrs. Li, 66 years old, is an old patient of ours. Her case was also presented last July (click on the blue text to jump to the reading) . Now, another year has passed, how is she doing now?

 Case Analysis

If you cannot understand the subsequent professional description,

Due to unbearable abdominal pain, Mrs. Li suspected stomach pain and went to the hospital for an abdominal and pelvic CT scan. The results showed a nearly 3cm space-occupying lesion in the pancreatic body, with adjacent structures involved, suggesting pancreatic cancer.

Mrs. Li immediately underwent radical resection of the pancreatic body and tail cancer in May 2019. The pathological results showed moderately-to-poorly differentiated adenosquamous carcinoma, with small foci presenting sarcomatoid structure and focal obvious fibrosis, without definite intravascular thrombus or neural invasion. Immediately afterward, she received four cycles of adjuvant chemotherapy with gemcitabine and temozolomide. After chemotherapy, the results showed a reduction in the accumulation of fluid in the abdominal and pelvic cavity, indicating that the disease had been somewhat controlled.

However, upon reexamination three months later, the MR results revealed suspicious abnormal signals in the residual pancreatic parenchyma, and the abnormal signals in the right lobe of the liver were similar to those previously observed. Meanwhile, the tumor marker CEA gradually increased and exceeded the normal range.

These reexamination results were not ideal, indicating a continued trend of disease progression, and the previous chemotherapy had not effectively suppressed the disease.

Mrs. Li and her family were very worried. After contacting Professor Zhang Minghui and his team from Tsinghua University School of Medicine, Professor Zhang analyzed Mrs. Li's condition:

Assessment of Mrs. Li's condition

 Pancreatic cancer is highly malignant, and the pathological types of patients are complex - "moderately-poorly differentiated", "adenosquamous carcinoma", and there are also "sarcomatoid" structures, posing a high risk of subsequent recurrence and metastasis.

   

The patient developed an accumulation of fluid in the abdominal and pelvic cavity after surgery. Although it decreased after adjuvant chemotherapy, it still persists and cannot be taken lightly.

   

 The routine follow-up after chemotherapy indicated suspicious signals in the residual pancreas and right lobe of the liver. Considering the elevated tumor marker, the possibility of disease progression in the patient has increased.

 NKT cell immunotherapy can delay the time of recurrence and metastasis, and currently represents the optimal time for patients to undergo treatment.

In December 2019, Mrs. Li underwent NKT cell therapy. Due to her high risk of recurrence and metastasis, an intensive regimen of two courses per month was adopted for treatment initially.

 

Treatment Results

In July 2020, half a year later, the patient completed 8 courses of continuous systemic treatment. Through 3 follow-up visits and imaging examinations, no clear signs of tumor recurrence were found, and the tumor marker CEA decreased to normal values. indicates that the high risk of recurrence and metastasis has been suppressed.

Now that one year of treatment has passed, Mrs. Li, who has completed 15 courses, not only did not show clear signs of tumor recurrence or metastasis on imaging during the re examination in January 2021; The previously elevated CEA has returned to normal levels; The remaining CA125 and CA19-9 are within the normal range.

Science popularization tips

Many patients or their families feel nervous and anxious when they see an increase in tumor markers, which is completely unnecessary. The elevation of tumor markers can predict the trend of tumor development, but it does not strictly correspond. Fluctuations of up and down are also common situations. So a single increase or decrease cannot indicate a problem. Continuous monitoring can only determine whether the disease is progressing or improving if there is a trend of increase or decrease.  
Mrs. Li reported feeling more energetic than before. Immediately after her surgery, she required assistance to walk and her quality of life score was only 78 points.

Now, after a year of treatment, her appetite has improved, and her quality of life has significantly increased - her quality of life score has reached 90.5 points, and she even rides a shared bicycle to and from her treatments.

 Treatment Overview Analysis

>>On December 12, 2018, the patient underwent a CT scan of the abdominal and pelvic cavity, which revealed a low-attenuation mass with a rough margin in the pancreatic body, measuring approximately 2.9*1.8cm. The possibility of pancreatic body cancer with adjacent structural involvement was considered.
>>On December 18, 2018, a pancreatic mass biopsy was performed. Pathology revealed poorly differentiated cancer infiltration.
>>On April 9, 2019, the normal range of tumor markers was as follows: CEA 4.28ng/ml and CA19-9 <0.6U/ml. On May 6, 2019, laparoscopic exploration was performed under general anesthesia, followed by open radical resection of the pancreatic body and tail cancer.

>>On May 17, 2019, the pathology report showed: ① (Resected specimens of pancreas, spleen, and left adrenal gland): Based on morphological and immunohistochemical results, the lesion was consistent with moderately-to-poorly differentiated adenosquamous carcinoma, with small foci presenting sarcomatoid structures and focal areas with significant fibrosis. No definite intravascular thrombus or neural invasion was observed, and no cancer was found at the pancreatic resection site. No definite metastasis was observed in the lymph nodes around the pancreas. No definite cancer involvement was found in the spleen and adrenal gland; ② (Resected end of hepatic artery nerve plexus) was examined and found to consist of fibrous adipose connective tissue and nerve fiber bundles, with no cancer observed; ③ (Resected end of celiac trunk mesenteric artery nerve plexus) was examined and found to consist of fibrous adipose connective tissue and nerve fiber bundles, with no cancer observed.

>>From June 25, 2019, to September 24, 2019, four cycles of adjuvant chemotherapy with gemcitabine and temozolomide were administered. On June 18, 2019, a follow-up abdominal CT scan showed: the resection site of the pancreatic body and tail and spleen, as well as the left adrenal gland, had undergone surgery; the fluid accumulation in the abdominal and pelvic cavity had decreased compared to previous scans.

>>On September 25, 2019, CT showed: 1. A few fibrous strands in both lungs; 2. Small nodules in the left lower lobe of the lung. On September 26, 2019, an upper abdominal MR plain scan showed: changes after resection of the pancreatic body and tail and spleen, as well as the left adrenal gland; suspicious abnormal signals in the residual pancreatic parenchyma, with no abnormal high signals on DWI; the abnormal signals in the right lobe of the original liver were similar to those observed previously (June 19, 2019). On September 3, 2019, tumor markers indicated: CEA 8.44ng/ml↑; on September 10, 2019, tumor markers indicated: CEA 6.74ng/ml↑.

>>Starting from December 10, 2019, NKT cell immunotherapy was administered, with a regimen of 2 courses per month. So far, 15 courses have been completed (as of January 7, 2021).
