Abstract
Description
完全寛解(CR) 腫瘍が完全に消失
進行(PD) 腫瘍の大きさの和が20%以上増加かつ絶対値でも5mm以上増加、あるいは新病変が出現
維持(SD) 腫瘍の大きさに変化なし
本実施形態の選択方法では、血清中の所定の物質を摂取前候補物質として用いている。ケトン食を摂取前の癌患者に由来する血清について、摂取前候補物質の少なくとも1種の分析結果を指標とすることによって、ケトン食を摂取する前に、ケトン食療法が有効な癌患者を選択することができる。
以下、本発明を実施例により具体的に説明するが、本発明はこれらの実施例により限定されるものではない。
(1)最初の1週間は、カロリーは、実質体重をもとに30kcal/kgとし、脂質制限なし、蛋白質制限なし、炭水化物10g以下を目標とした。具体的には、例えば、実質体重を50kgとすると、1日カロリー1500kcal、脂質140g、蛋白質60g、炭水化物10gとした。
CR群: 2例(女性2名、ともに肺癌、1例は56才、159cm、49.8kg、もう1例は53才、151cm、44.3kg)
PD/SD群: 3例(男性3名、肺癌1例、膀胱癌1例、口唇腺様嚢胞癌1例、50.6±13.0才、174.1±0.23cm、61.5±5.8kg、BMI 20.3±1.9)
ケトン食摂取前後の癌患者から採取された血清を、HPLCを用いたアミノ酸測定により分析し、得られたピーク面積を用いて統計解析を実施した。
CR群: 3例(女性3名、肺腺癌1例、卵巣癌1例、非小細胞肺癌1例、55.0±1.7才、155±4.0cm、46.5±2.9kg)
PD/SD群: 10例(女性6名、男性4名、乳癌2例、左口唇腺様嚢胞癌、盲腸癌腹膜幡腫、乳癌直腸癌、非小細胞肺癌、膀胱癌、直腸S状結腸癌、左副咽頭間隙悪性腫瘍、転移性肺腫瘍が各1例、58.5±15.5才、162.1±7.7cm、54.4±9.5kg)
