- the prognosis of cancer patients is reflected in the number of years of survival after the start of treatment, for example, in the case of humans, the prognosis is good when surviving for 5 years after the start of treatment, and the prognosis is achieved when death occurs in less than 5 years after the start of treatment. It may be judged as defective.
- SIL6R is also a prognostic marker that can efficiently distinguish between patients with a long prognosis and patients with a short prognosis.
- the prognosis prediction marker blood concentration range or threshold may be set in the same manner as described in “Method of predicting therapeutic effect of chemoradiotherapy”, and the prognosis may be predicted based on the range.
- Example 1 This example shows that the therapeutic effect of chemoradiotherapy on cancer tissue is related to the survival rate of the patient.
- the chemoradiotherapy was performed continuously from the first day to the fifth day of each week for 4 weeks.
- Fluorouracil (5-FU, Kyowa Hakko Kirin Co., Ltd.) 350 mg / m 2 (patient body surface area) and CDDP (Nippon Kayaku) 5 mg / m 2 (patient body surface area) were administered per day, and each treatment period A total of 7000 mg / m 2 and a total of 100 mg / m 2 were administered.
- radiation was irradiated at 2 Gy per day, and a total of 40 Gy was irradiated during the entire treatment period.

- the survival of the 37 esophageal squamous cell carcinoma patients was followed up to 9 years after the longest treatment was started.
- the 9-year survival rate of the group of patients who achieved a grade 3 effect by chemoradiotherapy was about 80%, whereas the group of patients who achieved a grade 1 or 2 effect was 9 years.
- the survival rate was about 20%.
- the therapeutic effect of chemoradiotherapy correlates with patient survival.
- Example 2 This example shows that the biomarkers sIL6R, MIP-1 ⁇ and PAI-1 can predict the therapeutic effect of chemoradiotherapy.
- sIL6R Three types of bios, sIL6R, MIP-1 ⁇ , and PAI-1, were collected from the above esophageal squamous cell carcinoma patients before chemoradiotherapy using fluorescent bead array system Luminex (Hitachi Soft) or sandwich ELISA. Markers were measured.
- FIGS. 2A and 2B show the sIL6R concentration in each patient in the grades 1, 2, and 3.
- the sIL6R concentration was significantly lower in the grade 3 patient group than in the grade 1 + 2 patient group.
- FIG. 3 shows the MIP-1 ⁇ concentration in each patient in the grade 1, 2, 3 group.
- the MIP-1 ⁇ concentration is significantly higher in the grade 3 patient group compared to the grade 1 + 2 patient group. It was low.
- FIG. 4 shows the PAI-1 concentration in each patient in the grade 1, 2, 3 group, which is significantly higher in the grade 3 patient group compared to the grade 1 + 2 patient group. it was high.
- the sIL6R concentration was significantly lower in the effective group (grade 3) than in the non-effective group (grades 1 and 2).
- the blood concentrations of sIL6R, MIP-1 ⁇ , and PAI-1 are the group in which the therapeutic effect of chemoradiotherapy is effective (grade 3) and the group in which the therapeutic effect is ineffective (grades 1, 2). ), There is a significant difference. Therefore, the therapeutic effect of chemoradiotherapy can be predicted using these biomarkers.
- the concentration distribution in the effective group overlaps with the distribution in the non-effective group. Therefore, these markers are particularly useful in finding individuals for whom chemoradiotherapy is ineffective. For example, by setting the maximum value of sIL6R and MIP-1 ⁇ concentration in the effective group as a threshold and specifying an individual whose concentration is higher than the threshold, it is possible to effectively identify an ineffective individual. For individuals whose concentration is lower than the threshold, there is a high probability that chemoradiotherapy is effective, so chemoradiotherapy may be performed, but it is preferable to make a judgment depending on the situation.
- the concentration distribution of PAI-1 in the non-effective group overlaps with the distribution of PAI-1 in the effective group. Therefore, this marker is particularly effective in finding individuals for whom chemoradiotherapy is particularly effective.
- the maximum value of PAI-1 concentration in the non-effective group as a threshold and specifying an individual whose concentration is higher than the threshold, it is possible to effectively identify an individual who is highly effective. For individuals whose concentration is lower than the threshold, there is a high probability that chemoradiotherapy is not effective, so chemoradiotherapy may not be performed, but it is preferable to judge according to the situation.
- Example 3 This example shows that the prognosis of a patient can be predicted by the biomarker according to the present application.
- the prognosis of the patient can be predicted by the biomarker sIL6R according to the present invention.
- sIL6R reflects only the therapeutic effect and prognosis by chemoradiotherapy in patients with esophageal squamous cell carcinoma, and does not reflect other factors.
- sIL6R is a biomarker independent of the patient's age, sex, and site of cancer occupancy and is associated with staging.
- biomarker for determining the application of chemoradiotherapy for cancer patients and a method for measuring the biomarker.
