Definitions
- the present invention relates to a diagnosis support system, a diagnosis support method, and a recording medium that support a task of distributing a large amount of pathological tissue specimens to a plurality of pathologists.
- pathologists perform pathological diagnosis on a large number of pathological tissue specimens.
- a pathological specimen is prepared by a laboratory technician and the pathologist in charge of the diagnosis is determined, the pathologist observes with a microscope or the like to make a diagnosis of cancer (malignant) or not (benign) used.
- the laboratory technician determines which pathologist is to diagnose each pathological tissue specimen with reference to pathologist information such as the working day, skills, specialized organs, and processing time of the pathologist. At this time, it is necessary to distribute the pathological tissue specimen to an appropriate pathologist, but since this distribution is performed based on the empirical rule of the individual of the laboratory technician, it is not always appropriate.
- the “difficulty in diagnosis” of tissue samples was subject to subjective judgments based on empirical rules by engineers, and accuracy and consistency were poor.
- Patent Document 1 discloses a technique related to a pathological diagnosis system that searches for a pathologist (requested pathologist) who wants to obtain an opinion on a case in a second opinion.
- the requested pathologist's search method is based on the pathologist's search items (organ type, target tissue area, cancer possibility, schedule, diagnosis performance (number of times)), and diagnoses for samples with high cancer possibility It is described that a pathologist who has a large track record (number of diagnoses) is preferentially selected.
- the technique of the above patent document has the following problems. That is, the laboratory technician cannot assign a tissue sample in the boundary region where it is difficult to determine whether or not it is malignant to a pathologist who has a high skill level, and as a result, there is a risk of misdiagnosis.
- An object of the present invention is to provide a diagnosis support system, a diagnosis support method, and a recording medium for recording a diagnosis support program that solve the above problems.
- a diagnosis support system includes an input unit that inputs a malignancy level of a tissue sample, a storage unit that stores a diagnosis person and the skill level in association with each other, and the malignancy level. Control means for determining the diagnostician whose skill level is equal to or higher than a reference value with reference to the storage means.
- diagnosis support method inputs a malignancy of a tissue sample, stores a diagnosis person and the skill level in association with each other, and the skill level is an intermediate value when the malignancy is an intermediate value. Is determined to be greater than or equal to a reference value.
- the diagnosis support program includes an input step for inputting the malignancy of the tissue specimen, and a storage step for storing the diagnoser and the skill level in association with each other.
- a diagnosis that causes a computer to execute a control step of determining the diagnostician whose skill level is equal to or higher than a reference value with reference to the skill level stored in the storage step when the malignancy is an intermediate value Record the support program.
- FIG. 1 is a diagram illustrating a configuration of a diagnosis support system 100 according to the present embodiment.
- the diagnosis support system 100 in this embodiment includes a control unit 10, a storage unit 20, an input unit 30, and an output unit 40.
- each part which comprises the data management apparatus of each embodiment is comprised by hardware, such as a logic circuit.
- Each unit includes a computer control circuit, a storage device, a program loaded in the storage device, a storage unit such as a hard disk for storing the program, and the like, and may be realized by any combination of hardware and software. As long as there is no notice, the realization method and apparatus are not limited.
- the control unit 10 refers to the storage unit 20 and determines a diagnostician having a skill level equal to or higher than a reference value as a diagnostic sample of the tissue sample.
- the intermediate value is a value indicating a boundary region in which it is difficult to determine whether the tissue sample is malignant or benign. For example, when the output value of the tissue specimen malignancy determination system (when the malignancy is output at 0 to 1.0) takes a value between 0.25 and 0.75, these are the intermediate malignancy. Value.
- the storage unit 20 stores a diagnosis person who diagnoses a tissue specimen and its skill level in association with each other.
- the skill level indicates a higher value as, for example, the number of tissue samples diagnosed by the diagnostician or the years of diagnostic work experience of the diagnostician increases.
- the input unit 30 acquires the malignancy of the tissue specimen to be diagnosed from a user terminal connected to the diagnosis support system 100.
- the output unit 40 outputs the tissue specimen diagnoser determined by the control unit 10 to a user terminal or the like.
- the skill level of the pathologist is represented by, for example, the years of diagnosis experience of the pathologist.
- FIG. 3 is a diagram showing an operation procedure until the diagnosis support system 100 distributes the tissue specimen to a pathologist having a high skill level.
- the control unit 10 determines whether or not the value indicates an intermediate value (S1).
- the control unit 10 determines that the malignancy value is an intermediate value, the control unit 10 reads the table in FIG. 2 from the storage unit 20 and searches for a pathologist to which a tissue specimen is assigned. The control unit 10 sets the subscript i to 1 (S2). Referring to FIG. 2, since the number of pathologists d [i] to be candidates for distribution is 6, the condition of subscript i ⁇ the number of pathologists is satisfied (Yes in S3). Further, the control unit 10 determines whether or not the skill level of each pathologist is equal to or greater than a predetermined reference value (S4).
- the predetermined reference value is, for example, a diagnosis experience of 5 years or more.
- the control unit 10 first determines whether or not the skill level of the pathologist aaa of d [1] is greater than or equal to a predetermined reference value. Since the skill level (year of diagnosis experience) of the pathologist aaa of d [1] is 10 years, the control unit 10 determines that the skill level is equal to or higher than a predetermined reference value (Yes in S4). At this time, if the skill level of the pathologist aaa of d [1] is less than or equal to a predetermined reference value, the control unit 10 subsequently determines that the skill level of the pathologist aba of d [2] is a predetermined level. It is determined whether or not the reference value is exceeded (No in S4, S8, S3, S4).
- control unit 10 repeats this operation until a pathologist with a high skill level is found (S3, S4, S8 loop).
- the control unit 10 determines whether or not the assigned number + 1 of the pathologist with high skill level, for example, the pathologist aaa of d [1], exceeds the assignable number (S5).
- the control unit 10 determines that the pathologist aaa can be assigned (S5). No), the tissue specimen is assigned to the pathologist aaa, and the ID of this pathologist is output (S6). Finally, 1 is added to the allocated number of pathologists aaa to update the allocated number (S7).
- the control unit 10 then continues to the pathologist with the next highest skill level, for example, d [2 ], It is determined whether or not the allocated number +1 of the pathologist aba exceeds the allocatable number (Yes in S5, S8, S3, S4, S5).
- control unit 10 repeats this operation until an assigned pathologist for the tissue specimen is found.
- the control unit 10 assigns the assigned number in order from the pathologist with the lowest skill degree. A pathologist who has not reached the possible number is searched, and tissue samples are sorted (S9 to S13).
- the malignancy value is extremely high, for example, the malignancy value is 1.0, and when the malignancy value is extremely low, for example, the malignancy value is 0. This is the case. Since the specific flow up to the search is the same as the above example, it is omitted here.
- the diagnosis support apparatus 100 in the present embodiment can reduce the risk of misdiagnosis during diagnosis of a tissue specimen. This is because, when the control unit 10 determines that the malignancy value of the tissue sample is an intermediate value, the diagnosis of the tissue sample is assigned to a pathologist with a high skill level with reference to the storage unit 20. is there.
- FIG. 4 is a diagram showing a configuration of a diagnosis support system 100 according to the second embodiment of the present invention.
- the diagnosis support system 100 includes a control unit 10, a storage unit 20, and an input unit 30.
- the control unit 10 refers to the storage unit 20 and determines the diagnostician having a skill level equal to or higher than a reference value.
- the storage unit 20 stores the diagnoser and the skill level in association with each other.
- the input unit 30 inputs the malignancy of the tissue sample.
- the diagnosis support system 100 can reduce the risk of misdiagnosis during diagnosis of a tissue specimen. This is because, when the control unit 10 determines that the malignancy value of the tissue sample is an intermediate value, the diagnosis of the tissue sample is assigned to a pathologist with a high skill level with reference to the storage unit 20. is there.

Abstract
Description
以下、図面を参照して本発明による診断支援システム100の実施形態を説明する。ただし、以下の実施形態に記載されている構成要素はあくまでも例示であり、本発明の技術的範囲をそれらのみに限定する趣旨のものではない。
制御部10で、悪性度の値が中間値であると判断した場合、制御部10は、記憶部20から図2の表を読み出し、組織標本を割当てる病理医を検索する。制御部10は、添え字iを1とする(S2)。図2を参照すると、振分けの候補となる病理医数d[i]は6名であるため、添え字i≦病理医数の条件を満たす(S3のYes)。さらに、制御部10は、各々の病理医のスキル度が所定の基準値以上か否かを判断する(S4)。所定の基準値とは、例えば、診断経験年数が5年以上である。制御部10は、図2を参照し、まず最初にd[1]の病理医aaaのスキル度が所定の基準値以上か否かを判断する。d[1]の病理医aaaのスキル度(診断経験年数)は、10年であるため、制御部10は、スキル度が、所定の基準値以上であると判断する(S4のYes)。このとき、d[1]の病理医aaaのスキル度が、所定の基準値以下であった場合には、続いて、制御部10は、d[2]の病理医abaのスキル度が所定の基準値以上であるか否かを判断する(S4のNo、S8、S3、S4)。
組織標本の悪性度が中間値でなく、例えば、悪性度の値が極端に高い、若しくは極端に低いなどといった場合、制御部10は、スキル度の1番低い病理医から順に割当済数が割当可能数に到達していない病理医を検索し、組織標本の振分けを行う(S9~S13)。ここで、悪性度の値が極端に高い場合とは、例えば、悪性度の値が1.0の場合であり、悪性度の値が極端に低い場合とは、例えば、悪性度の値が0の場合である。検索までの具体的な流れは、前記例と同様のため、ここでは省略する。
図4は、本発明の第2の実施形態に係る診断支援システム100の構成を示す図である。本実施形態に係る診断支援システム100は、制御部10、記憶部20、及び入力部30を包含する。制御部10は、組織標本の悪性度が中間値である場合に、記憶部20を参照して、スキル度が基準値以上の前記診断者を決定する。記憶部20は、診断者とそのスキル度を対応付けて記憶する。入力部30は、組織標本の悪性度を入力する。
