Common treatments include surgery, radiotherapy, chemotherapy, and radiation therapy. Surgical intervention is often followed by additional treatment, e.g., hormone therapy, lymph node irradiation, or CT. Chemotherapy is often used or complemented by hormonal therapy, radiotherapy, and surgery. Radiation therapy can be used alone or in addition to other treatments. Radiation therapy combined with surgery can delay local recurrence but is not generally indicated in lymph node-negative adenocarcinoma. The effects of CT in lung cancer are unclear. Radiotherapy in lung cancer is generally not recommended. Overall 5-year survival has not improved in the United States.
About 5.3 million new cases of adenocarcinoma are expected to be diagnosed in the US each year, making it the most common form of lung cancer. Adenocarcinoma typically occurs early among African Americans and men, and later among women.\n
The pathogenesis of adenocarcinoma is not fully understood; for example, tumor viruses have been shown to influence the development of pancreatic cancer. Adenocarcinoma may be a multi-genic disorder where many genes are involved not only in genetic susceptibility but also in tumor formation. The pathogenesis also seems to be influenced by environmental factors of which the dietary intake is the main one.
Adenocarcinoma should be staged by a combination of MRI, CT, PET, and endoscopic evaluation. Appropriate therapy can often be achieved in the setting of meticulous followup.
Most common signs of adenocarcinoma are a cough lasting>3 months, a fever with a rapid increase, erythema nodosum or lesions on the skin (e.g. swollen neck lymph nodes). Rarely, the disease involves the lung parenchyma and may therefore cause a dyspnoea which is a typical sign of adenocarcinoma.
Adenocarcinoma is the type of cancer most often to make up lung cancers. An adenocarcinoma is formed from cells made up primarily of glands that have grown together, and their interiors are covered with a thin layer of liquid, mucus, which, when the tumor is present, makes it readily identifiable when the tumor is grown. This is a cancer of the lungs, where the cells form a thin mucus covering (mucus is created by goblet cells). Adenocarcinoma is formed by the cells growing together and forming sheets which can eventually form a tumor. This cancer must also have spread to other areas of the lung, particularly the lymphatic system.
The mean distance of local spread is about 13 mm, which is comparable with the reported mean distances of 12 and 18 mm of local spread of adenocarcinoma of the lung and the ocular adenocarcinoma. The prognosis of patients with early-stage disease does not seem to be poorer than that of patients with distant-spread disease.
In the absence of an obvious predisposing risk factor, the etiologic role of H pylori in adenocarcinoma of the colon remains elusive. This review demonstrates the necessity for large prospective, controlled, prospective cohort studies. Such studies will help to establish the association of H pylori with adenocarcinoma, and evaluate immunological response to H pylori.
The risk of developing adenocarcinoma after long-standing, benign polyps may depend in part on the individual genotypes of the genes coding for MLL2 and MSH2. The use of the Bethesda guidelines could refine the management of patients with a family history of adenocarcinoma, especially those with an MSH2 or MLL2 mutation.
Age-adjusted cancer-specific mortality was higher for AA than whites in the AASMC cohort and was higher for AA when adjusted for socioeconomic status in the OSCCW cohort. This suggests that age-adjusted cancer-specific mortality may be a inappropriate outcome for clinical trials in AA.
This review describes the common areas and common effects of radiation therapy for cancers of the breast, salivary glands, prostate, colon, and lung. Understanding these effects will help people remember the signs and symptoms of breast cancer, oral cancer, and other maladies, and will support the clinician when counseling patients about radiation therapy. All radiation oncologists should be aware of the changes in normal tissues that occur after radiation therapy. It is essential that patients understand their likelihood of benefits and treatment-specific side effects.
The families with HNPCC-associated carcinomas present a greater frequency of cases of siblings with endometrioid adenocarcinomas. This suggests that these two types of carcinoma may have common risk factors.
