Abstract

The present invention addresses the problem of providing a composition that inhibits muscle loss in cancer patients and is useful in improving the cancer patients' life expectancy and QOL. This muscle loss inhibiting composition for cancer patients is, for example, a high-lipid, low-hydrocarbon composition, and contains a long-chain fatty acid triglyceride and/or a middle-chain fatty acid triglyceride as a lipid, and a protein and a saccharide. The term "muscle loss inhibiting composition for cancer patients" means a composition that literally inhibits muscle loss in cancer patients, and can also refer to a composition that slows the rate of muscle loss in cancer patients. The muscle loss inhibiting composition for cancer patients may consist solely of a protein, a lipid, and a saccharide. The term "composition" is intended to include substances that can be ingested by animals (including humans) such as: formulations including fluid diets, supplements, food additives, and the like; foods and beverages (other than whole animals and plants); and food and beverage compositions (including processed foods and beverages).

Description

Cancer patient muscle mass reduction inhibitory composition

The present invention relates to a composition for suppressing a decrease in muscle mass of a cancer patient, and a composition for reducing the rate of decrease in muscle mass of a cancer patient.

Many cancer patients are prone to malnutrition, so 60 to 80% of cancer patients have muscle loss due to malnutrition. Loss of muscle in cancer patients causes deterioration in quality of life (QOL) and treatment compliance of cancer patients, and is regarded as a problem in the clinic (see, for example, Non-Patent Document 1).

Muscle loss associated with cancer continues to deteriorate unless the progression of the tumor is suppressed, and there may also be a deterioration in the nutritional status due to cancer treatments such as anticancer drugs and radiation (see, for example, Non-patent Document 2). Furthermore, if the weight or muscle mass of a cancer patient falls below a certain value, the cancer patient may not be able to receive anticancer drug treatment. Therefore, treatment that maintains the nutritional status and reduces the tumor without losing weight and muscle is desired (see, for example, Non-Patent Document 3).

In recent years, multidisciplinary treatment combining nutrition therapy and non-drug treatment has been provided in addition to existing cancer treatment such as drug treatment, and it may be more useful than monotherapy for cancer. . For example, cancer patients are known to actively take oral nutritional supplements and the like containing eicosapentaenoic acid (EPA) etc. and try to suppress the reduction of their own body weight and muscle mass. (For example, refer to nonpatent literature 4). In addition, Japanese Patent Application Publication No. 2013-508411 (patent document 1) provides cancer patients with up to 50% of the calories normally consumed, at least 50% of them, as a method of reducing cancer growth or cancer symptoms. A method is described comprising the steps of obtaining calories from fat and giving the patient a maximum of 500 kcal / day for the next predetermined period. Furthermore, WO 2017/038101 describes compositions for treating cancer, including a high fat diet.

EXAMPLES Hereinafter, the present invention will be described in more detail by way of examples, but the present invention is not limited to the following examples.

On the day of the start of the test, 25 CDF1 mice were divided into three groups, and 5 × 10 ⁵ colon cancer-derived Colon 26 cells were transplanted subcutaneously into CDF1 mice belonging to two groups (N = 10). Hereinafter, these two groups are referred to as “tumor-bearing mouse group”, and CDF1 mice belonging to the tumor-bearing mouse group are referred to as “tumor-bearing mice”. Then, CDF1 mice belonging to one remaining group (N = 5 mice) were not transplanted with colon cancer-derived Colon 26 cells, and CDF1 mice were kept normal. Hereinafter, this one group is referred to as a "normal group", and CDF1 mice belonging to the normal group are referred to as "normal mice".

Next, for 21 days from the day of the test start, purified animal diet AIN-93G (composition: see Table 1, ketone ratio) in tumor-bearing mice belonging to one of the tumor-bearing mice, and CDF1 mice belonging to the normal group 0.08) was fed ad libitum. Thereafter, tumor-bearing mice and normal mice were dissected, and their weights and gastrocnemius muscle weights were measured using an electronic balance. The results are shown in FIGS. Hereinafter, a group in which tumor-bearing mice are fed a purified feed for animals AIN-93G is referred to as a "tumor-bearing control group".

On the other hand, Meiji Ketone Formula 817-B (composition: see Table 2; ketone ratio: 3) to feed freely. After that, the tumor-bearing mice were dissected, and their weights and gastrocnemius weights were measured using an electronic balance. The results are shown in FIGS. Hereinafter, a group in which a tumor-bearing mouse is fed with Meiji Ketone Formula (registered trademark) manufactured by Meiji Co., Ltd. is referred to as "KF group".

As shown in FIG. 1, the weight of normal mice in the normal group was significantly heavier than that of tumor-bearing mice in the tumor-bearing control group and those in the KF group at 21 days after the start of the test. The weight of tumor-bearing mice in the KF group was significantly greater than the weight of tumor-bearing mice in the tumor-bearing control group.

In addition, as shown in FIG. 2, the weight of normal mice in the normal group increased in 21 days, but the weight of tumor-bearing mice in the tumor-bearing control group and those in the KF group decreased in 21 days. The weight loss of the tumor-bearing mice in the KF group was significantly less than the weight loss of the tumor-bearing mice in the cancer-bearing control group.

As shown in FIG. 3, the total energy intake of tumor-bearing mice in the KF group from the start of the test to the 21st day elapsed is the total energy intake of tumor-bearing mice in the normal group and the tumor-bearing control group. It was significantly more than the amount.

And, as shown in FIG. 4, the gastrocnemius muscle weight of the normal mice of the normal group at the 21st day after the start of the test is significantly more than that of the tumor-bearing mice of the tumor-bearing control group and the tumorigenic mice of the KF group Although heavy, the gastrocnemius muscle weight of the tumor-bearing mice in the KF group was significantly heavier than that of the tumor-bearing control mice. That is, it was possible to conclude that the rate of decrease in gastrocnemius muscle was alleviated in the tumor-bearing mice of the KF group that ingested Meiji Ketone Formula (registered trademark) manufactured by Meiji Co., Ltd.

The composition for suppressing muscle mass loss in cancer patients according to the present invention is useful for prolonging the survival prognosis of cancer patients and improving QOL by maintaining the nutritional status of cancer patients and suppressing the decrease in muscle in cancer patients. is there.
