How is adenoid cystic carcinoma staged, and how is adenoid cystic carcinoma treated?

Adenoid cystic carcinoma is an epithelial ** malignant tumor, with a high degree of malignancy, easy to local invasion, and is not very sensitive to chemoradiotherapy, and its occurrence and development are relatively fast.

Local invasion and distant metastases can occur early on, and the overall prognosis is not very good.

At present, the comprehensive sequence based on surgery is still the main method of adenoid cystic carcinoma, and the normal boundary of surgery should be expanded when the surgical design is made, and extensive resection of local tumors and some surrounding normal tissues is the main principle of adenoid cystic carcinoma.

** sexual or advanced tumors in addition to extensive resection, can be combined with radiation**, some anatomical parts can not be completely **, also need to cooperate with radiation ** after surgery, radiation ** may reduce the chance. For cases that lose the opportunity for surgery, radiation** can also be used to control the progression and prolong the course of the disease.

Problems with surgical resection of adenoid cystic carcinoma (right maxillofacial area).

Beijing Cancer Hospital is a hospital with experience in tumors, and it is recommended to make an appointment with Professor Zhu Guangying from their hospital.

It is recommended to kill residual cancer cells through Chinese herbal medicine after surgery, improve immunity, prevent metastasis, etc., effectively control the disease, so that the patient's condition can be significantly improved in the shortest time and achieve the most ideal effect.

** of advanced tracheal adenoid cystic carcinoma.

Hello, cancer is a systemic disease, and the effect will be more significant if you combine a variety of diseases. Radiotherapy is radiation, which has a certain effect on the body, such as decreased appetite, nausea, vomiting, abdominal pain, diarrhea or constipation and many other toxic side effects, must be combined with traditional Chinese medicine to take Chinese herbal medicine, Chinese medicine has the effect of strengthening the right and dispelling evil, replenishing qi and nourishing blood, which can improve the body's immunity, alleviate the toxicity of Western medicine such as radiotherapy and chemotherapy, reduce the pain of patients, kill residual cancer cells, and improve the quality of life.

It is recommended that you can still choose a local tertiary hospital or specialized hospital for examination, the effect is still ***, I wish you good health!

Early adenoid cystic carcinoma**.

This situation can be combined with traditional Chinese medicine**, soothing the liver and regulating qi, strengthening the spleen and invigorating qi, which may have a certain curative effect.

Parotid adenoid cystic carcinoma.

If it is the early stage of the tumor, the degree of malignancy is not high, and radiotherapy can be omitted. To promote blood circulation and eliminate blood stasis, you can eat American ginseng, Ganoderma lucidum, and Rhodiola rosea.

At this point, pain relief is still necessary, and the surgery will not adversely affect the progression of the disease.

Hello, it is recommended to use traditional Chinese medicine to take Chinese herbal medicine, treat both the symptoms and the root causes, kill cancer cells, improve immunity, etc., effectively control the disease, so that the patient's condition can be significantly improved in the shortest possible time, and the most ideal effect is best to use surgical resection, and after the operation, the use of traditional Chinese medicine dynamic **take Chinese herbal medicine for comprehensive recuperation and comprehensive**, prevent**, effectively control the disease, and achieve the purpose of thoroughly**.

The location of the lesion, the size of the tumor, and whether the surgery was completely removed are factors that directly correlate with the prognosis of the patient. Adenoid cystic carcinoma is prone to local metastasis and often metastasizes distantly many times. The main cause of death is local destruction or distant metastasis.

The tumor develops slowly, and even ** can survive for many years.

1.Laboratory tests.

Histopathological changes: no intact capsule, pale section or with hemorrhagic cystic changes. Under light microscopy, columnar basal-like cells constituted 5 histological images, including cribriform (Swiss pie-like); tubular; solid type; Acne-type; Hardened type.

2.Other investigations.

1) X-ray examination has no special findings in the early stage, and enlargement of the lacrimal gland fovea and osteolytic bone destruction can be seen in the late stage.

2) Ultrasonography showed a vacant lesion in the lacrimal gland area, which was flat or fusiform in shape, with clear boundaries, uneven internal echogenicity, moderate sound attenuation, and irregular posterior boundary of the tumor. A ultrasound showed that the reflex in the lesion was irregular and attenuated. A Doppler scan may show an abundant blood supply within the tumor.

3) CT scan of adenoid cystic carcinoma shows more special signs, mostly showing high-density space-occupying lesions in the upper orbital area, and the shape is flattened, fusiform or irregular. The lesion grows along the external wall of the orbit towards the orbital apex with obvious enhancement. In the early stage, there can be no bone destruction, and this growth pattern is unique, accounting for more than 80% of cases.

Some lesions spread to the advanced intracranial stage through the supraorbital fissure, and the lesions infiltrate the bone and cause bone destruction.

4) MRI examination showed that the tumor was moderately low on T1WI, and T2WI was hyperintense or moderately high intensity, and the enhancement was obvious. The tumor has a wide range on MRI, invading the bone and surrounding structures, such as the hemorrhagic necrotic cavity of intracranial tumors in the temporal fossa, showing a medium to high heterogeneous signal on TLWI. Because there is no signal on MRI of bone, especially on T1Wi, if the tumor is a medium signal, the bone is not well shown when the signal is low, and the tumor signal is generally high on T2Wi, and the MRI of bone destruction that is still low signal can be better displayed at this time.

Adenoid cystic carcinoma, like other types of salivary gland malignancies, can be difficult to diagnose preoperatively. Patients with early pain and nerve palsy in the salivary gland mass should first consider the diagnosis of adenoid cystic carcinoma. In order to further confirm the diagnosis, fine-needle aspiration cytology can be done, and the tumor cells can be seen to be round or oval, similar to basal cells, and clustered in a pellet shape; The mucus is pellet-shaped and has one or more layers of tumour cells around it.

This unique finding is not found in other salivary gland epithelial tumors and can be diagnosed as adenoid cystic carcinoma.

Adenoid cystic carcinoma accounts for 5% to 10% of salivary gland tumors and 24% of salivary gland malignancies. It is more common in the salivary glands and is common in the palatine glands. Although there are fewer salivary glands, they are tumors of the submandibular and sublingual glands.

It accounts for only 2% to 3% of parotid gland tumors. There is no significant difference in incidence between men and women, or slightly more in women. The most common age is 40-60 years old.

In the early stage of the tumor, there are mostly ** masses, and a few cases have pain at the time of discovery, and the nature of the pain is intermittent or persistent. Some of the pain is mild, while others can be severe. The course of the disease is prolonged, months or years.

The tumor is generally not large, mostly in 1 3 cm. The shape and characteristics of the mass may resemble a mixed tumor, round or nodular shape, and smooth. Most of the masses have unclear borders and poor mobility, and some are more fixed and adherent to surrounding tissues.

Tumors often spread along nerves, and adenoid cystic carcinoma occurring in the parotid gland can cause facial nerve palsy, and can extend along the facial nerve to involve the mastoid process and temporal bone; Adenoid cystic carcinoma of the submandibular or sublingual glands, which can extend along the lingual or hypoglossal nerve to sites far from the primary tumor and cause impaired tongue sensation and movement on the affected side; Adenoid cystic carcinoma of the palate can extend along the maxillary nerve into the skull, destroying the bone at the base of the skull and causing severe pain. Tumors also often invade adjacent bone tissue, such as the mandible bone in the submandibular and sublingual glands; Occurs in the palate, often involving the palatal bone. When small salivary adenoid cystic carcinoma involves the mucosa, in addition to touching a hard, small nodular mass on the surface, a distinct, reticulate dilated capillary is often seen.

Adenoid cystic carcinoma is also known as cylindroma or cylindromatous adenocarcinoma. Adenoid cystic carcinoma is the most common lacrimal gland malignant epithelial tumor and the most malignant, ranking second only to pleomorphic adenoma in the incidence of lacrimal gland epithelial tumor. The disease progresses rapidly, and local spread or distant metastasis can occur early on.

The common clinical manifestations are proptosis, inward and inferior displacement, pain numbness, ptosis, and diplopia caused by tumor infiltration of blood vessels, nerves, bone tissues and extraocular muscles, and pain is the main clinical symptom. A palpable adhesive mass at the orbital rim that is ill-bordered and tender.
