10-year survival rates for mucinous tumors is excellent in the absence of invasion. In the case of borderline tumors confined to the ovary and malignant tumors without invasion, the survival rates are 90% or greater. In invasive mucinous cystadenocarcinomas, the survival is approximately 30%. Survival in metastasis is between 12 and 30 months. [5]
The five-year survival rate for all stages of ovarian cancer is 46%; the one-year survival rate is 72% and the ten-year survival rate is 35%. [132] For cases where a diagnosis is made early in the disease, when the cancer is still confined to the primary site, the five-year survival rate is 92.7%. [133]
Ovarian cancer incidence rates are low in East Asia [56] and highest in Europe, the United States, and Australia/New Zealand. [57] Since 1975, survival rates for ovarian cancer have steadily improved with a mean decrease of 51% by 2006 of risk of death from ovarian cancer for an advanced stage tumour. [58]
As with endometrial carcinomas, the prognosis is influenced by the grade and type of the adenocarcinoma, being poorest with serous differentiation. MMMTs are highly malignant; a stage I tumor has an expected five-year survival rate of 50%, while the overall five-year survival rate is less than 20%. [1] Staging of uterine MMMTs is as follows: [3]
A malignant mucinous neoplasm is called a mucinous carcinoma. For example, for ovarian mucinous tumors , approximately 75% are benign , 10% are borderline and 15% are malignant. Mucinous carcinoma
The most common cancer among women in the United States is breast cancer (123.7 per 100,000), followed by lung cancer (51.5 per 100,000) and colorectal cancer (33.6 per 100,000), but lung cancer surpasses breast cancer as the leading cause of cancer death among women. [13]
According to research, most ovarian cancers start at the epithelial layer which is the lining of the ovary. Within this epithelial group ovarian clear-cell carcinoma makes up 5–10%. It was recognized as a separate category of ovarian cancer by the World Health Organization in 1973. Its incidence rate differs across various ethnic groups.
Serous cystadenocarcinoma is a serous tumor in the cystadenocarcinoma grouping.. Most commonly, the primary site of serous cystadenocarcinoma is the ovary.Rare occurrence in the pancreas has been reported, although this is not typical, with the majority of microcystic pancreatic masses representing alternate disease processes such as the more benign serous cystadenoma.
