    • Apparatus for in situ radiotherapy has a flexible catheter having a proximal end for receiving a radioisotope and a distal end for positioning the flexible catheter within a patient to be treated. An anchor, which is permanently connectable to tissues deep inside the patient, has a sealing collar connected to it which seals the distal end of the catheter. The catheter also includes a plug near the distal end which seals the distal end in addititon to the seal provided by the sealing collar. The anchor has a penetration point connected to it to assist a surgeon in implanting the catheter within a tumor. A threaded fastener on the anchor is screwed into the catheter. The flexible catheter can be released remotely from the anchor by unscrewing it. A suture eye is connected to the anchor. The suture eye may be sutured to healthy tissue within the patient when the apparatus is implanted to secure the anchor to the patient. When the radioisotope is not being received, the proximal end of the catheter is sealed by a cylindrical plug connected to a manipulation handle.
    • 用于原位放射治疗的装置具有柔性导管,其具有用于接收放射性同位素的近端和用于将柔性导管定位在待治疗患者内的远端。 永久连接到患者深处的组织的锚固件具有连接到其上的密封套,其密封导管的远端。 导管还包括靠近远端的塞子,该密封件除了由密封套环提供的密封件之外密封远端。 锚固件具有连接到其的穿透点,以帮助外科医生将导管植入肿瘤内。 锚固件上的螺纹紧固件被拧入导管中。 柔性导管可以通过旋转将其远离锚点释放。 缝线眼连接到锚。 当植入装置以将锚固定到病人身上时,缝线眼可被缝合到患者体内的健康组织。 当放射性同位素未被接收时,导管的近端通过连接到操纵手柄的圆柱塞密封。

    • Azido-, 4-nitro and 2,4-dinitrophenylhydrazones as well as 4,4'-dihydroxybenzophenone-hydrazone and other hydrazones are disclosed which have antiestrogenic activity useful in treating estrogen-requiring tumor cells. The described hydrazones bind to estrogen receptors in the cytoplasm of tumor cells. The azido-, 4-nitro- and 2,4-dinitro-phenyl branches of the molecules appear to bind to the receptors and prevent translocation of estrogenic information into the nucleus, thereby blocking the synthesis of necessary macromolecules such as proteins. Absence of geometric isomerization from antiestrogenic to estrogenic forms of the drug minimizes estrogenic side-effects.

    • A method is disclosed for predicting response of a tumor patient to therapy, and selecting appropriate therapy for malignant neoplasms such as breast, ovarian and gastrointestinal cancer. A sample of tumor cells is cultured in the presence of 10 .mu.g/ml estradiol, and inhibition of cell growth in the culture paradoxically indicates an estrogen dependent tumor that will respond to antiestrogenic therapy. Another sample of tumor cells is cultured in the presence of a chemotherapeutic agent which predicts response of the tumor to in vivo administration of a cytotoxic agent. The chemotherapeutic agent is preferably a cytotoxic drug, or a drug having both cytotoxic and antiestrogenic mechanisms of action. A particularly suitable substance having both mechanisms of action is: ##STR1## wherein R.sup.1 H, OH, OOC(CH.sub.2).sub.2 CO.sub.2 H or CH.sub.3 COO; R.sup.2 is C.sub.6 H.sub.4 OH, C.sub.6 H.sub.4 OCOCH.sub.3, C.sub.6 H.sub.4 OOC(CH.sub.2)CO.sub.2 H, or C.sub.6 H.sub.5 ; and X is C.sub.6 H.sub.3 -2,4(NO.sub.2).sub.2, C.sub.6 H.sub.5, C.sub.6 H.sub.4 -4(NO.sub.2), C.sub.6 H.sub.4 -3(NO.sub.2), or C.sub.6 H.sub.3 -2,4(NO.sub.2).sub.2 ;Predictive power of the assay is increased by combining information from the estradiol and chemotherapeutic assays. These assays are preferably performed in culture flasks having removable bases that function as conventional microscope slides.
    • 公开了一种用于预测肿瘤患者对治疗的反应并选择适合于恶性肿瘤如乳腺癌,卵巢癌和胃肠癌的治疗的方法。 肿瘤细胞样本在10μg/ ml雌二醇的存在下培养,并且培养物中细胞生长的抑制反而表示雌激素依赖性肿瘤,其将对抗雌激素疗法作出反应。 在化学治疗剂存在下培养另一个肿瘤细胞样品,该化学治疗剂预测肿瘤对体内施用细胞毒性剂的反应。 化学治疗剂优选是细胞毒性药物,或具有细胞毒性和抗雌激素作用机制的药物。 具有两种作用机理的特别合适的物质是:其中R 1 H,OH,OOC(CH 2)2 CO 2 H或CH 3 COO; R2是C6H4OH,C6H4OCOCH3,C6H4OOC(CH2)CO2H或C6H5; X为C6H3-2.4(NO2)2,C6H5,C6H4-4(NO2),C6H4-3(NO2)或C6H3-2.4(NO2)2; 通过组合来自雌二醇和化学治疗测定的信息来增加测定的预测能力。 这些测定优选在具有作为常规显微镜幻灯片起作用的可移除碱基的培养瓶中进行。
