(1) dividing patients with the same disease into N groups, adopting different intervention treatment measures in each group, and respectively listing the survival time of each group of patients;
(2) solving the survival rate of each group, and finding out a group with the highest survival rate at the M time point;
(3) recording the intervention measures of the group with the highest survival rate, collecting or gathering more cases under the intervention measures to form an expanded group, listing the survival time of patients in the expanded group, and generating a survival distribution map of the expanded group;
(4) intercepting the second half part of the survival rate in the survival distribution graph which obviously begins to increase, and listing the survival time of the interception section of the expansion group;
(5) listing the characteristic values of all patients in the enlarged group intercepting segment, numbering the characteristic codes of the patients, calculating the occurrence frequency of each characteristic code, finding out the characteristic code with the occurrence frequency of 1 or the highest occurrence frequency, namely the characteristic code commonly owned by the patients or the code most frequently possessed by the patients, and then determining the optimal treatment method of the disease patient with the specific characteristic value.
The invention analyzes different intervention treatment measures of the same disease, analyzes the intervention measure with better effect by calculating survival rate, fills and expands data, digitalizes the characteristics of the patient, and finally obtains the optimal treatment method of the disease patient with corresponding characteristic value, so as to scientifically adjust and treat according to the characteristics of the patient.
The more preferable technical scheme of the invention is as follows:
in the step (2), the survival rate is calculated by, in the case of M time points in total, the number of survival cases in the mth period = the number of initial cases in the mth period-the number of effective cases in the mth period, and the survival probability in the mth period = the number of survival cases in the mth period/the number of initial cases in the mth period, and then the survival rate in the mth period = the survival rate in the M-1 th period × the survival probability in the mth period.
In the step (3), the survival distribution map of the expanded group is generated by using EXCEL with the patient number as the horizontal axis and the survival time as the vertical axis.
In the step (5), the method for calculating the occurrence frequency of the feature code comprises the following steps: the frequency of occurrence of the feature code = the number of occurrences of the feature code/total number of patients in the enlarged group truncation.
A population of patients sensitive to a particular intervention is selected, and the optimal treatment for that type of patient is determined to be the particular intervention.
The invention makes full use of the existing disease treatment data, accurately analyzes different specific measures and effects to obtain the optimal intervention measures of the diseases under different characterization states, further improves the cure rate of the diseases, and is suitable for wide popularization and application.
(IV) description of the drawings
The invention will be further described with reference to the accompanying drawings.
FIG. 1 is a graph showing the survival distribution of an expanded group of the present invention.
(V) detailed description of the preferred embodiments
In order to more fully understand the technical contents of the present invention, the technical solutions of the present invention will be further described and illustrated with reference to the following specific embodiments.
Example (b):
the total number of the lung cancer patient group files is 2, the intervention measure adopted by the patient group 1 is western medicine A treatment, and the intervention measure adopted by the patient group 2 is traditional Chinese medicine B treatment. The information of survival time, treatment mode, lung cancer type and the like in the file can be retrieved. It is desirable to find valuable information therefrom, particularly information on effective treatments or optimal treatment regimens for different lung cancer patients, as described below.
Step one, the survival time of 2 patients is listed as shown in table 1 and table 2 (note: + indicates invalid data or deleted data).
TABLE 1 survival time (month) for patient group 1
Figure DEST_PATH_IMAGE001
TABLE 2 survival time (month) for patient group 2
Figure 844891DEST_PATH_IMAGE002
And step two, calculating the survival rate of each group as shown in tables 3 and 4 (note: + represents invalid data or deletion data, so that the death number of the patient with + mark is not counted when the survival probability is calculated).
Table 3 survival rate of patient group 1
Figure DEST_PATH_IMAGE003
Table 4 survival rate of patient group 2
Figure 558769DEST_PATH_IMAGE004
The 46-month survival rate of group 1 was 0.13, and the 46-month survival rate of group 2 was 0.125. Therefore, the group with the highest survival rate at the 46 month time point was group 1, and the intervention measure adopted in group 1 was western medicine a.
Step three, recording the intervention measures adopted by the patient group 1 as western medicine A treatment, collecting cases under the intervention measures in a file to form an expanded group, and listing the survival time of the patients in the expanded group, as shown in table 5.
TABLE 5 extended survival time (month)
Figure DEST_PATH_IMAGE005
The survival profile of the expanded group was generated using EXCELL (see FIG. 1).
Step four, intercepting the latter half part of the distribution graph, in which the survival rate obviously begins to increase, and listing the survival time of the intercepted segment of the expanded group, as shown in table 6.
TABLE 6 Life time of the extended group intercept segment (moon)
Figure 167867DEST_PATH_IMAGE006
Step five, listing the characteristic values of all patients in the intercepted segment of the enlarged group, and numbering the characteristic codes of the patients, as shown in table 7.
The characteristic values of this group of patients are summarized below, in letters, and the patient characteristics represented by each letter are as follows: a small cell lung cancer, B non-small cell lung cancer, C cystic adenoid cancer, D before receiving radiotherapy, E before receiving chemotherapy, and F before receiving targeted drug therapy.
TABLE 7 eigenvalues of the extended group intercept segment
Figure DEST_PATH_IMAGE007
Calculating the occurrence frequency of each feature value, wherein the occurrence frequency of the feature code = the occurrence frequency of the feature code/the total number of patients in the enlarged group truncation section.
The occurrence frequency of the characteristic value B is 1, the occurrence frequency is the highest, and then the patients sensitive and effective to the intervention measure have the common characteristic code B, namely the patients sensitive and effective to the intervention measure which is treated by the western medicine A are all non-small cell lung cancer patients. The effective intervention measures of the Western medicine A for the non-small cell lung cancer patient are obtained through the algorithm.
The technical contents of the present invention are further described by way of examples only so as to facilitate understanding of the present invention for those skilled in the art, but the present invention is not limited thereto, and any technical extension or re-creation based on the present invention is protected by the present invention.
