Overview

There is no established system for the classification of [disease name].

OR

[Disease name] may be classified according to [classification method] into [number] subtypes/groups: [group1], [group2], [group3], and [group4].

OR

[Disease name] may be classified into [large number > 6] subtypes based on [classification method 1], [classification method 2], and [classification method 3]. [Disease name] may be classified into several subtypes based on [classification method 1], [classification method 2], and [classification method 3].

OR

Based on the duration of symptoms, [disease name] may be classified as either acute or chronic.

OR

If the staging system involves specific and characteristic findings and features: According to the [staging system + reference], there are [number] stages of [malignancy name] based on the [finding1], [finding2], and [finding3]. Each stage is assigned a [letter/number1] and a [letter/number2] that designate the [feature1] and [feature2].

OR

The staging of [malignancy name] is based on the [staging system].

OR

There is no established system for the staging of [malignancy name].

Classification

• Appendix cancer may be classified according to WHO classification into 4 groups:

• Epithelial tumors
• Non-epithelial tumors
• Secondary tumors
• Hyperplastic (metaplastic) polyp

• The table below summarizes the different types of appendix cancer according to the WHO classification.

WHO histological classification Tumors of the appendix Adapted from WHO/IARC
Epithelial tumors
Adenoma Tubular Villous Tubulovillous Serrated Carcinoma Adenocarcinoma Mucinous adenocarcinoma Signet-ring cell carcinoma Small cell carcinoma Undifferentiated carcinoma Carcinoid (well differentiated endocrine neoplasm) Tubular carcinoid Goblet cell carcinoid (mucinous carcinoid) Mixed carcinoid-adenocarcinoma Others
Non-epithelial tumors
Neuroma Lipoma Leiomyoma Gastrointestinal stromal tumor Leiomyosarcoma Kaposi sarcoma Others
Secondary tumors
Metastasis (eg. Primary of urogenital tract, breast, lung)
Hyperplastic polyp
