Does stage II rectal cancer require chemotherapy?
Whether a stage II colorectal cancer patient needs adjuvant chemotherapy after surgery depends on the specific circumstances. For example, stage IIA patients are classified as T3, N0, M0. The necessity of adjuvant chemotherapy for these patients should be determined based on the pathological report. If the report indicates the presence of vascular invasion, neural invasion, poor differentiation, or if microsatellite stability testing shows poor prognostic factors, then such patients should undergo postoperative adjuvant chemotherapy. If none of these conditions are present in a stage IIA patient, then postoperative adjuvant chemotherapy may not be necessary. Generally, stage IIB patients, whose tumors have penetrated the full thickness of the intestinal wall, are recommended to undergo postoperative adjuvant chemotherapy. Therefore, the specific conditions of the patient need to be considered.
Typical symptoms of prostate cancer
Early-stage prostate patients often do not exhibit significant clinical symptoms. However, when the prostate cancer tumor invades the surrounding tissues and structures, it can cause corresponding clinical manifestations such as urinary tract irritation and urinary obstruction. Symptoms include difficulty urinating or frequent urination, painful urination, and even urinary incontinence, perineal pain, and sciatica. Bone metastasis is a common site of metastasis in prostate cancer patients, causing pain in the affected area and even pathological fractures.
How to screen for pancreatic cancer
Pancreatic cancer is a common malignant tumor of the digestive tract. Due to its high malignancy and rapid progression, it severely affects human health. So how should pancreatic cancer patients be screened? Generally, abdominal ultrasound examination is the primary screening method. Another method is the examination of tumor markers, mainly carcinoembryonic antigen (CEA) and CA19-9. CA19-9 is a tumor marker with relatively high specificity and sensitivity for the diagnosis of pancreatic cancer. Therefore, during physical examinations, we can draw blood to check these tumor markers. If there is a significant increase in CA19-9 or CEA, further examinations of the pancreas, such as ultrasound or CT of the pancreas, should be conducted to further investigate whether there is a tumor in the pancreas.
How is liver cancer diagnosed?
In clinical practice, if a patient has a history of chronic hepatitis B and imaging tests, such as an enhanced CT or MRI of the liver, suggest a radiological appearance of liver cancer, combined with an AFP level greater than 400 persisting for four weeks, these conditions can support a clinical diagnosis of liver cancer. However, for a confirmed diagnosis, a liver biopsy guided by ultrasound or CT must be performed. The definitive diagnosis of liver cancer relies on identifying cancer cells through pathological examination.
Rectal cancer stage III
Rectal cancer staging is based on the TNM system. "T" refers to the primary tumor, and its stage depends on which layer of the bowel wall the tumor has invaded. "N" is based on whether there are lymph node metastases and the number of lymph nodes involved. "M" indicates whether there are metastases to distant organs. Staging is determined according to the TNM situation, where Stage I is the earliest and Stage IV is the latest. Stage III indicates lymph node metastasis without distant organ metastases, such as to the liver or lungs. In such cases, irrespective of whether T is T1 to T4, if there is lymph node involvement without distant organ metastasis, it is staged as Stage III.
What are the symptoms of esophageal cancer recurrence?
The symptoms of recurrent esophageal cancer are similar to those at its initial onset, primarily characterized by difficulties in swallowing and eating obstructions. Some may also experience nausea, vomiting, and reflux symptoms of the digestive tract. Of course, when recurrence occurs, if there are metastases to other distant organs, then clinical manifestations corresponding to those metastatic locations will appear. For example, if esophageal cancer metastasizes to the lungs, it could lead to coughing, expectoration, shortness of breath, or chest pain, and even clinical symptoms related to coughing up blood. If there is liver metastasis from esophageal cancer, symptoms might include abdominal pain, fatigue, poor appetite, and even ascites among other clinical manifestations related to liver metastasis.
Stage IV rectal cancer
In the staging of rectal cancer, we generally use the TNM staging system clinically. "T" refers to the primary tumor, "N" indicates whether there is lymph node metastasis, and staging is based on the status of the lymph nodes. "M" indicates whether there is distant metastasis. Stage IV refers to any stage of "T" and any stage of "N", as long as there is distant metastasis, such as rectal cancer metastasizing to the liver, lungs, or bones. When these distant organ metastases occur, the staging is M1, any "T", any "N", M1. This scenario is stage IV, indicating the presence of distant organ metastasis and represents advanced stage rectal cancer patients.
What to do about pancreatic cancer pain?
Pancreatic cancer pain is common in clinical practice, with some patients presenting with abdominal pain as their initial symptom. Pain management can be symptomatic, using analgesics for relief. For mild pain, tramadol can be chosen for pain relief. For severe pain, opioid analgesics such as morphine sustained-release tablets, oxycodone sustained-release tablets, or morphine tablets can be used for pain relief. These are merely symptomatic treatments. The fundamental approach involves surgical or oncological treatments like chemotherapy or radiotherapy to treat pancreatic cancer. Only when the tumor is controlled will the symptoms of pain be alleviated.
Does early-stage stomach cancer hurt?
Symptoms of early-stage gastric cancer are generally not very obvious. Some patients may experience subtle symptoms resembling those of gastritis or gastrointestinal ulcers, including non-specific gastrointestinal symptoms such as discomfort and bloating in the upper abdomen, acid reflux, nausea, vomiting, and decreased appetite. In terms of pain, early-stage gastric cancer patients might only experience a sensation of bloating or mild tenderness in the upper abdomen. Severe pain is usually associated with late-stage gastric cancer, occurring when there is extensive abdominal metastasis or tumor progression, and the tumor is large enough to cause significant pain, requiring analgesics for treatment.
What medicine is infused into the bladder for bladder cancer?
Postoperative intravesical chemotherapy infusion is very common in the treatment of bladder cancer. Common drugs used for infusion chemotherapy include mitomycin and anthracyclines such as epirubicin or pirarubicin. Gemcitabine is also frequently used for this purpose. The related side effects generally include irritation symptoms of the bladder, although some patients may experience relatively mild side effects.
