Question 200 on sigmoid colon cancer

There is no inevitable connection between what medicine is used and metastasis, it will not metastasize if it is not an imported drug, your lesions are more general, I can only roughly say the characteristics of lung metastases. Most of the lung metastases are first seen in the lower lung near the subpleura, and the edge of the lung texture distribution is clear with small nodules of soft tissue density, the small density is uniform, and the large ** can be seen with low-density necrosis, and the absolute value of enhanced scanning does not exceed 100hu.

6 months after colon cancer surgery. Postoperative chemotherapy for 6 months.

Is CEA, CA1909 or CA724 not being monitored?

If the above TMS is monitored, it decreases postoperatively, decreases during chemotherapy, and is currently on an upward trend, then metastases are assumed. If a shadow is found on chest x-ray, immediate CT examination is recommended.

No matter what the drug is, it is not guaranteed to be 100% effective. Intense, long-term chemotherapy can also cause great damage to the body's immune function.

Hello. The colon enters the lungs through the mesenteric lymph, if it was diagnosed 6 months ago, it is really time to check the lungs, and chemotherapy can inhibit cancer cells, and at the same time it also damages normal cells, and the body's resistance is not high, so check the lungs as soon as possible.

What are your CT results now? Cytotyping of the excised tissue? Immunohistochemistry? Whether the left lung shadow is close to the main bronchus, if so, you can try a biopsy with a fibroscopy to confirm the diagnosis or rule it out.

Don't wait, do a chest CT scan right away.

1. Like ordinary colon cancer, sigmoid colon cancer is divided into four stages, phase I, stage II, stage III and stage IV, with stage I and stage II belonging to the early stage, stage III belonging to the intermediate stage, and stage IV belonging to the advanced stage of sigmoid colon cancer.

2. Sigmoid colon cancer, in fact, it is only adenocarcinoma in the glandular epithelium of the sigmoid colon, which is a kind of colon cancer, the main manifestations are changes in the shape of stool, fatigue, anemia accompanied by melena, unexplained weight loss, and symptoms of abdominal pain and bloating.

3. Sigmoid colon cancer, like other cancers, is the prognosis after surgery, and the early or late detection of the tumor, as well as the way and method, whether it is clean or not, if the early stage of sigmoid colon cancer, after surgery, the five-year survival rate can reach more than 90%, can be completely **.

4. The probability of mid-stage sigmoid colon cancer can also reach about 70% to 80% after first-class surgery. Relatively advanced, including distant metastases, after the current ** surgery, after the simultaneous resection of distant liver metastases and lung metastases or through chemotherapy, etc., the five-year survival rate can reach about 30-40%.

1. Early symptoms: Abdominal distention, discomfort, and indigestion-like sigmoid cancer symptoms may occur in the early stage, and then changes in bowel habits, such as increased bowel movements, diarrhea or constipation, and abdominal pain before defecation. Later, there may be mucus or mucopurulent bloody stools.

2. Poisoning symptoms: due to tumor ulceration and blood loss and toxin absorption, it can often lead to anemia, low-grade fever, fatigue, emaciation, edema and other symptoms of sigmoid colon cancer, especially anemia and emaciation.

3. Manifestations of intestinal obstruction: incomplete or complete low intestinal obstruction symptoms, such as abdominal distention, abdominal pain, constipation or stool. Physical examination reveals abdominal distortion, bowel, local tenderness, and strong bowel sounds.

4. Abdominal mass: The symptoms of sigmoid colon cancer are tumors or masses that invade and adhere to the omentum and surrounding tissues, which are hard and irregular, and some can have a certain degree of activity with the intestinal tube, and the tumor is more invasive in the advanced stage, and the mass can be fixed.

For the staging of bowel cancer, the modified dukes stage is often used internationally. Dukes staged in China: Phase A:

The cancer is confined to the intestinal wall. Stage B: The cancer penetrates the intestinal wall and invades the serous membrane or (and) the serous membrane, but there is no lymph node metastasis.

Stage C: Presence of regional lymph node metastases, in which only the tumor and celiac lymph nodes are in C1 stage, while the lymph nodes in the mesentery and mesenteric lymph nodes are in C2 stage. Phase D:

There are distant metastases or abdominal metastases, or invasive adjacent organs that cannot be removed.

There are 4 stages of sigmoid colon cancer, and when sigmoid colon cancer is detected by the body, it must be resected by surgery as soon as possible**, and chemotherapy is also required after resection**. If sigmoid colon cancer** is not timely, it is very likely to metastasize, and the first metastasis is the liver and lungs, so after the operation, it is necessary to pay close attention to the changes in the body and communicate with the doctor in time.

DUKES stage in China: stage A: cancer is confined to the intestinal wall; Phase B:

Cancer penetrates the intestinal wall and invades the serous membrane or/or extraserosally, but there is no lymph node metastasis; Stage C: with regional lymph node metastasis, which is limited to tumor and paraintestinal lymph nodes for C1 stage, and metastasis to mesangial and mesangial root lymph nodes for C2 stage; Stage D: Patients with distant metastases or abdominal metastases, or those who invade adjacent organs and cannot be removed.

Hello! In the advanced stage, the focus is on relieving pain, improving symptoms, and prolonging the survival of patients as much as possible, while traditional Chinese medicine cancer focuses on starting from the root of cancer, focusing on the root of cancer, focusing on the overall condition, which can well stabilize the disease, prevent the disease from metastasizing, and prolong the survival of patients to the greatest extent.

Discussion, the ascending colon mass is located on the right side of the abdomen, abdominal pain, and abdominal distention: for the symptoms of rectosigmoid colon cancer must be paid attention to, bowel sound and its intestinal type is obvious, abdominal pain, or constipation, can also be occasionally increased in the frequency of bowel movements, rectal cancer is mainly manifested as an increase in the frequency of stools. 1. Abdominal tenderness, severe pain, blood in the urine and other symptoms may occur, progressive anemia.

Cancer invades the bladder, abdominal distention, and urgency to urinate. Obstruction of the proximal bowel may be permanently distended. 2. The main manifestations of right colon cancer are dyspepsia, and the colon liver bracket mass is located in the right upper abdomen, and the lesion has entered the most advanced stage at this time, which is answered as follows.

The cecal cancer mass is located in the right lower quadrant. Rectal cancer can also cause intestinal obstruction and loss of appetite. 3。

Because the cancer can invade the sacral plexus, fatigue and thinning of the stool. The location of the mass varies depending on the location of the lesion, with abdominal mass, alternating episodes of diarrhea, diarrhea, and lack of oxygen leading to ulceration. Because the obstruction is mostly in the lower sigmoid colon, it is prone to stenosis and progressive intestinal obstruction, and left-sided colon cancer is due to the narrow lumen of the sigmoid colon, and the transverse colon mass is located near the umbilicus, accompanied by tenesmus.

When the cancer breaks down. In addition, there may be fever, with blood or mucus, ischemia, and form an acute angle with the rectum, emaciation, can form a vesicorectal fistula, and even cause perforation, which can make the feces stained with blood or mucus, and have complications such as perforation and localized abscess, constipation, so the vomiting is mild or absent, and there are many intractable constipation. If the bladder is involved, urinary frequency and dysuria may occur.

You mentioned that the symptoms of rectosigmoid cancer can also occur with large amounts of blood and intra-abdominal abscesses.

The patient is currently diagnosed with postoperative sigmoid colon cancer PT3N1M0 stage III A with intestinal obstruction before surgery.

Adjuvant chemotherapy should be given postoperatively.

Further testing for CEA KRas can also be performed

To observe the effect of Zen therapy and individualization**.

Dr. Wang Jufeng of Henan Provincial Cancer Hospital solemnly reminded that because the patient cannot be seen face-to-face and cannot fully understand the condition, the above Jian's discussion is for reference only, and the specific diagnosis and treatment must be carried out in the hospital under the guidance of the doctor! ）

Surgery can only remove visible cancerous tissue, and it cannot do anything about cancer cells hidden in blood, body fluids, tissues, and lymph. Secondly, if even a single cancer cell falls during the operation, it will begin to grow and spread and metastasize if it falls anywhere in the body. The third is that surgery is a large trauma, and the remaining cancer cells in the body after surgery are prone to low immunity**.

In addition, the constitution of cancer patients is already very weak, and surgery will cause greater trauma, which will lead to a serious injury to the vitality, further reduce the immune function, and is not conducive to the fight against cancer.
