Acinar adenocarcinoma of the lung is a highly lethal disease. Overall, the five-year survival rates approximate 16% to 22%. Generally, survival is better in all stages for patients with the acinar (or papillary) pattern than it is in patients with the solid pattern, but considerably worse than those with the bronchioloalveolar pattern.
Invasive adenocarcinoma of the lung includes a heterogenous mixture of subtypes and variants. The 2011 consensus describes five subtypes of invasive adenocarcinomas based on the cell pattern that is most predominant. These subtypes are described below: Histopathology of lepidic predominant adenocarcinoma. Acinar pattern. [16] Solid pattern. [17]
Survival rates for most childhood cancers have improved, with a notable improvement in acute lymphoblastic leukemia (the most common childhood cancer). Due to improved treatment, the 5-year survival rate for acute lymphoblastic leukemia has increased from less than 10% in the 1960s to about 90% during the time period 2003-2009.
A subtype of adenocarcinoma, the bronchioloalveolar carcinoma, is more common in female never-smokers, and may have a better long-term survival. [ 13 ] This cancer usually is seen peripherally in the lungs, as opposed to small cell lung cancer and squamous cell lung cancer , which both tend to be more centrally located.
Acinic cell carcinoma is a malignant tumor representing 2% of all salivary tumors. 90% of the time found in the parotid gland, 10% intraorally on buccal mucosa or palate. The disease presents as a slow growing mass, associated with pain or tenderness in 50% of the cases.
IDCP associated with invasive carcinoma (IDCP-inv) generally represents a growth pattern of invasive prostatic adenocarcinoma while the rarely encountered pure IDCP is a precursor of prostate cancer. [20] The diagnostic criterion of nuclear size at least 6 times normal is ambiguous as size could refer to either nuclear area or diameter.
In the United States during 2013–2017, the age-adjusted mortality rate for all types of cancer was 189.5/100,000 for males, and 135.7/100,000 for females. [1] Below is an incomplete list of age-adjusted mortality rates for different types of cancer in the United States from the Surveillance, Epidemiology, and End Results program.
If completely removed by surgery, the prognosis is excellent with up to 100% 5-year survival. [ 1 ] Although the entity of AIS was formally defined in 2011, [ 2 ] it represents a noninvasive form of pulmonary adenocarcinoma which has been recognized for some time.
