Pancreatic Cancer Discussion Post
Potential Sites for Metastasis
In the case of J.C, a patient diagnosed with pancreatic adenocarcinoma, according to
Usón et al. (2020), the potential most common sites for metastasis include the lungs, lymph
nodes and especially the liver. Metastasis occurs because cancers are cells that break away
from the primary tumor and invade nearby tissues and vessels, disseminate via circulatory
blood or lymphatic systemic channels to gain secondary locations where they form new
tumors. The liver is usually one of the earliest sites involved because of the direct venous
drainage from the pancreas to the liver, and lymphatic infiltration results in metastasis to
lymph nodes. Pancreatic cancer can spread to distant organs by hematogenous dissemination,
for instance, the lungs.
What are tumor cell markers and why tumor cell markers are ordered for a
patient with pancreatic cancer
Tumor cell markers are products made by the cancer cells or other cells in reaction to
the growth of cancer. Regarding pancreatic cancer, the two most prominent tumor markers
that are regularly requested include CA 19-9 and CEA (carcinoembryonic antigen).
According to Mizrahi et al. (2020), these markers serve several purposes like diagnosing,
prognosing, and treatment responce. For example, abnormalities resulting in elevated levels
of CA 19-9 and CEA are indicative of pancreatic cancer, and their test results can be used to
gauge the response or relapse after treatment.
Based on the case study described, proceed to classify the tumor based on the TNM
Stage classification. Why is this classification important?
The TNM (Tumor, Node, Metastasis) staging system for pancreatic cancer based on
the case study:
3

T: T2 (Tumor >2 cm and ≤4 cm) Solid mass in the head of the pancreas (4 cm)
infiltrating the Wirsung duct is present.

N: N1 (Regional lymph node metastasis) – detection of a perilesional node 1.5 cm,
with the presence of metastatic aspect.

M: M1, the solid mass invades the superior mesenteric vein.
The importance of TNM Staging is seen in granting provides with esential information
effortlessly. According to Usón et al. (2020), TNM staging is essential and facilitates
communication as it helps to guide treatment decisions and predict prognosis. There may be
different treatment methods required for various stages. Hence, staging gives insight into how
the disease is likely to progress.
Characteristic of malignant tumors regarding it cells, growth and ability to spread
Cell Characteristics: Malignant tumor cells usually show pleomorphism, which means a
variation in size and shape; hyperchromasia that involves abnormal dark-stained nuclei; and
an increased nuclear-to-cytoplasmic ratio. Growth: It is characterized by an uncontrolled and
invading growth of malignant tumors that destroy the tissues near them. Ability to Spread:
Malignant tumors have an ability to metastasize, that is they can spread to different organs
through the bloodstream or lymphatic system (Mizrahi et al., 2020).
Describe the carcinogenesis phase when a tumor metastasizes
Initiation is Mutations in the genes, frequently caused by carcinogens, lead to normal
cells becoming malignant cells, Promotion: The promoters stimulate the initiated cells to
grow, resulting in the formation of a primary tumor, and Progression: Cancer cells in this
stage are capable of invading neighboring tissues and metastasizing to remote locations,
forming secondary tumors (Mizrahi et al., 2020).

Choose the tissue level that is affected on the patient discussed above: Epithelial,
Connective, Muscle or Neural. Support your answer.
In the study of J.C, pancreatic cancer primarily influences the level of Connective
Tissues. The tumor originates in the exocrine part of the pancreas and invades the adjoining
connective tissue, blood vessels (superior mesenteric vein), potentially metastasizing to local
lymph nodes as well as distant organs. Pancreatic adenocarcinoma is characterized by the
infiltrative growth pattern, where it invades the connective tissue structures surrounding the
pancreas.
