Chapter II 第二章
Neoplasms (C00-D48)
肿瘤 ( C00-D48 )
This chapter contains the following broad groups of neoplasms:
本章含下列各大群的肿瘤 ：
C00-C75
Malignant neoplasms, stated or presumed to be primary, of specified
sites, except of lymphoid, haematopoietic and related tissue
肯定或推测为原发性恶性肿瘤 （ 淋巴、造血或其相
关组织除外 ）
C76-C80
Malignant neoplasms, of ill-defined, secondary and unspecified sites
未明示、续发性及未特定之恶性肿瘤
C81-C96
Malignant neoplasms, stated or presumed to be primary, of lymphoid,
haematopoietic and related tissue
淋巴、造血和相关组织肯定或推测为原发性恶性肿
瘤
C97
Malignant neoplasms of independent (primary)multiple sites
独立 （ 原发 ） 的多发部位之恶性肿瘤
D00-D09
In situ neoplasms
原位肿瘤
D10-D36
Benign neoplasms
良性肿瘤
D37-D48
Neoplasms of uncertain or unknown behaviour [see note, page 240]
未确定和不知作用的肿瘤〔参考第 240 页注解〕
1.
Primary,ill-defined, secondary and unspecified sites of malignant
neoplasms
Categories C76-C80 include malignant neoplasms for which there is no clear indication of
the original site of the cancer or the cancer is stated to be
"disseminated","scattered" or "spread" without mention of
the primary site. In both cases the primary site is considered to be unknown.
原发性、未明示、续发性和未特定部位的恶性肿瘤
C76-C80 包含没有清楚指示癌的原发部位 ， 或癌是 ＂ 散
发的 ″ 、 ＂ 散播的 ″ 或 ＂ 传布的 ″ 且未提及原发部
位者 ， 以上二者原发部位均被视为未知。
8.
Use of the second edition of International Classification of Diseases
for Oncology (ICD-O)
For certain morphological types, chapter Ⅱ provides a rather restricted topographical
classification, or none at all. The topography codes of ICD-O use for all neoplasms
essentially the same three-and four-character categories that chapter Ⅱ uses for
malignant neoplasms (C00-C77,C80), thus providing increased specificity of site for other
neoplasms (malignant secondary (metastatic), benign, in situ and uncertain or unknown).
It is therefore recommended that agencies interested in identifying both the site and
morphology of tumours, e.g. cancer registries, cancer hospitals, pathology departments and
other agencies specializing in cancer, use ICD-O.
使用第二版国际疾病分类 ( ICD-O ) 有关肿瘤学部份
在一些形态学上类型 ， 第二章提供一个有限的 （ 或
完全没有 ） 局部解剖分类 ， ICD-O 的局部解剖登录码使
用在所有肿瘤 ， 须有相同的叁或四码类别 ， 使用於
第二章原发性恶性肿瘤 （ C00-C77 , C80 ） ， 且提供其他肿
瘤的部位之特殊性 （ 恶性续发性 （ 转移性 ） 、良性
、原发和未确定或未知 ） 。
我们建议一些参与分辨肿瘤的部位和形态学的相关
机构人员 ， 如癌症登记、癌症医院、病理科和其他
癌症专门机构可使用 ICD-O 。

Mental and behavioural disorders due to multiple drug use and use of
other psychoactive substances [See pages 321-323 for subdivisions]

involved, hut it is impossible to assess which substance is contributing most to the
disorders. It should also be used when the exact identity of some or even all the
psychoactive substances being used is uncertain or unknown, since many multiple drug users
themselves often do not know the details of what they are taking.

Signs and symptoms that point rather definitely to a given
diagnosis have been assigned to a category in other chapters of the classification. In
general,categories in this chapter include the less well-defined conditions and symptoms
that, without the necessary study of the case to establish a final diagnosis, point
perhaps equally to two or more diseases or to two or more systems of the body. Practically
all categories in the chapter could be designated "not otherwise specified",
"unknown etiology" or "transient " The Alphabetical Index should be
consulted to determine which symptoms and signs are to be allocated here and which to
other chapters. The residual subcategories, numbered .8, are generally provided for other
relevant symptoms that cannot be allocated elsewhere in the classification.
症状与候相当清楚可列入其他章节之疾病诊断时 ，
须列在其他分类章节的范围内。一般来说 ， 列在本

立诊断的病况及候。实际来看 ， 本章的范围可视为
一些其他未明示的、病因欠明或暂时性的症状候 ，
可利用索引来查询症状或候所归类之章节。本章以
(.8) 来代表不易归类之相关症状的其他次分类项。
The conditions and signs or symptoms included in categories
R00-R99 consist of: (a) cases for which no more specific diagnosis can be made even after
all the facts bearing on the case have been investigated;(b) signs or symptoms existing at
the time of initial encounter that proved to be transient and whose causes could not be
determined;(c) provisional diagnoses in a patient who failed to return for further
investigation or care;(d) cases referred elsewhere for investigation or treatment before
the diagnosis was made;(e) cases in which a more precise diagnosis was not available for
any other reason; (f) certain symptoms, for which supplementary information is provided,
that represent important problems in medical care in their own right.
