Is the bladder cancer embryonic antigen high?
Carcinoembryonic antigen (CEA) is significantly elevated, mainly seen in gastrointestinal tumors, especially in colorectal cancers such as colon and rectal cancers, where CEA elevation is more pronounced. It can also be notably higher in patients with lung adenocarcinoma, and bladder cancer might show an increase in CEA as well. However, the increase in CEA is not necessarily consistent, and its diagnostic value for bladder cancer is limited due to low specificity and sensitivity, making it not very instructive. The definitive diagnosis of bladder cancer primarily involves cystoscopy and taking a biopsy to confirm the presence of cancer.
What are the symptoms of stomach cancer?
Symptoms of gastric cancer, especially in the early stages, generally include nausea, vomiting, loss of appetite, discomfort or bloating in the upper abdomen, pain, and acid reflux as some of the gastrointestinal symptoms, as well as vomiting blood and black stools. Black stools are tar-like stools, and their occurrence indicates bleeding in the upper gastrointestinal tract. Additionally, if the tumor causes pyloric obstruction, the patient will vomit food eaten the night before, be completely unable to eat, and experience a significant weight loss. In even more advanced stages, gastric cancer patients may develop a cachectic state.
How to treat advanced gastric cancer?
The treatment for advanced gastric cancer is primarily chemotherapy, especially for patients with peritoneal or retroperitoneal lymph node metastasis, or distant organ metastasis such as to the liver or lungs. The treatment primarily involves chemotherapy, specifically choosing either multi-drug intravenous combination chemotherapy or oral monotherapy, such as oral chemotherapy with tegafur capsules, or broad-spectrum targeted therapies like apatinib that inhibit angiogenesis. The choice of treatment depends on a comprehensive consideration of the patient's overall condition. If the patient's general condition is particularly poor and the chemotherapy risk is assessed to be high, then the approach for such advanced-stage patients is primarily the best symptomatic supportive treatment to alleviate suffering as much as possible. Therefore, the treatment plan must be determined based on a comprehensive consideration of the specific situation.
Can stomach cancer be cured?
Whether gastric cancer can be cured depends greatly on the stage at which it is discovered. Clinically, if there is no recurrence or metastasis within five years, it is considered cured. The treatment of gastric cancer is primarily surgical. Therefore, for early-stage gastric cancer patients, if a surgeon assesses that curative surgery is feasible, it is recommended to perform a radical surgical resection. For stage I gastric cancer patients, the five-year survival rate after surgical treatment can generally reach over 90%, which is quite effective. However, for those with advanced gastric cancer, it is generally incurable. Treatments, including chemotherapy, targeted therapy, or optimal symptomatic supportive care, aim to alleviate the patient's suffering and extend their life, but generally cannot cure advanced gastric cancer.
Early symptoms of lymphoma
The early symptoms of lymphoma patients are primarily due to its predilection for lymph nodes, with the majority of cases initially presenting with swollen lymph nodes in the neck or collarbone area. These lymph nodes usually enlarge progressively without pain, which is the most common early clinical symptom. However, some specific types of lymphoma, such as nasal NKT lymphoma, present with localized symptoms like nasal congestion, nosebleeds, or a runny nose. There are also lymphomas originating in the stomach, part of the digestive tract, whose symptoms include upper abdominal pain, nausea, or vomiting. Furthermore, some lymphomas originate in the skin, manifesting as skin nodules. Therefore, depending on the site of occurrence, the symptoms can vary, but the enlargement of superficial lymph nodes remains the primary clinical manifestation in most cases.
What are the symptoms of gastric cancer?
The symptoms of gastric cancer patients are generally common gastrointestinal symptoms such as nausea, vomiting, acid reflux, and discomfort and bloating in the upper abdomen, especially aggravated after eating. As the condition progresses, symptoms may include vomiting blood or black stools. When the cancer invades surrounding organs, clinical symptoms such as abdominal effusion, abdominal distension, and pain may occur. If the tumor is located near the pylorus and causes pyloric obstruction, symptoms of pyloric obstruction will appear, such as gastric retention, acid reflux, and vomiting of overnight food. Additionally, if the tumor bleeds, it may cause severe vomiting of blood. Therefore, different stages of the disease present different symptoms. If gastric cancer progresses to the late stage with metastasis to distant organs, clinical manifestations corresponding to the sites of metastasis will also appear.
How is gastric cancer treated?
The treatment methods for gastric cancer include surgery, chemotherapy, and radiotherapy, as well as broad-spectrum targeted therapies against angiogenesis, such as apatinib. Immunotherapy is also an option. However, the specific treatment plan is based on a comprehensive consideration of various factors, including the stage of the cancer and the general condition of the patient. The principle is that for early-stage gastric cancer patients, if the surgeon assesses that surgery is feasible, then radical surgical treatment is primarily used. For advanced-stage patients who are in generally good condition, chemotherapy is the main treatment, combined with a consideration of whether to undergo radiotherapy. For those in very advanced stages, who may not be in good health or those who have had chemotherapy with poor results, anti-angiogenic drugs like apatinib can be chosen as a subsequent treatment.
How is ovarian cancer screened?
The most commonly used screening method for ovarian cancer is the B-ultrasound examination of the adnexa uteri. The B-ultrasound can detect ovarian masses and tumors, and when these are found, the possibility of ovarian cancer should be considered, necessitating further examinations for confirmation. Another method involves the tumor marker CA125, which is relatively sensitive and specific for epithelial ovarian cancer. Therefore, for ovarian cancer screening, we can perform a blood test for CA125 in conjunction with a B-ultrasound of the adnexa uteri.
Lymphoma fever symptoms
Patients with lymphoma commonly exhibit symptoms such as fever, clinically referred to as B symptoms. Some patients may also experience additional B symptoms such as fatigue, sweating, or weight loss. Patients displaying these B symptoms generally have a poorer prognosis. Furthermore, lymphoma patients typically experience fever more frequently in the afternoon or evening, usually presenting with a low-grade fever. If the condition of a lymphoma patient is not controlled, their fever symptoms will recur repeatedly. Only when the condition is under control will there be an alleviation of fever symptoms. Anti-inflammatory drugs are not effective in these cases.
Does ovarian cancer cause abdominal pain every day?
Patients with ovarian cancer often experience abdominal pain as a common symptom. This is because ovarian cancer can widely implant itself within the pelvic and abdominal cavity, or directly invade the uterus, fallopian tubes, and other tissues and organs within the pelvis, resulting in symptoms of abdominal pain. However, not every patient with ovarian cancer will necessarily exhibit abdominal pain as a clinical symptom, nor is it the case that abdominal pain will occur every day. For instance, some patients with early-stage ovarian cancer may have more concealed clinical presentations and may not experience any specific discomfort. They might discover the disease through physical examinations, gynecological exams, or through ultrasound scans of the uterine adnexa conducted during physical check-ups.
