17. Patient who does not apply highly effective contraception during during the study and through the duration as defined below after the final dose of study treatment:

A condom is required to be used also by vasectomized men in order to prevent delivery of the drug via seminal fluid.

b. Women of child-bearing potential, defined as all women physiologically capable of becoming pregnant, must use highly effective contraception during the study and through at least 4 weeks after the final dose of study treatment c. Highly effective contraception is defined as either: i. Total abstinence: When this is in line with the preferred and usual lifestyle of the subject. [Periodic abstinence (e.g., calendar, ovulation, symptothermal, postovulation methods) and withdrawal are not acceptable methods of contraception].

ii. Female sterilization: have had surgical bilateral oophorectomy (with or without hysterectomy) or tubal ligation at least six weeks before taking study treatment. In case of oophorectomy alone, only when the reproductive status of the woman has been confirmed by follow up hormone level assessment iii. Male partner sterilization (with the appropriate post-vasectomy documentation of the absence of sperm in the ejaculate). [For female study subjects, the vasectomized male partner should be the sole partner for that patient] iv. Use a combination of the following (both a+b):

1. Placement of an intrauterine device (IUD) or intrauterine system (IUS)

2. Barrier methods of contraception: Condom or Occlusive cap (diaphragm or cervical/vault caps) with spermicidal foam/gel/ film/ cream/vaginal suppository.

3. Note: Hormonal contraception methods (e.g. oral, injected, and implanted) are not allowed as buparlisib decreases the effectiveness of hormonal contraceptives.

Women are considered post-menopausal and not of child-bearing potential if they have had 12 months of natural (spontaneous) amenorrhea with an appropriate clinical profile (e.g. age appropriate, history of vasomotor symptoms) or have had surgical bilateral oophorectomy (with or without hysterectomy) at least six weeks ago.

For women with therapy-induced amenorrhea, oophorectomy or serial measurements of FSH and/or estradiol are needed to ensure postmenopausal status.

NOTE: Ovarian radiation or treatment with a luteinizing hormone-releasing hormone (LH-RH) agonist (goserelin acetate or leuprolide acetate) is not permitted for induction of ovarian suppression.

18. Patient with poorly controlled diabetes mellitus (glycosolated hemoglobin > 8%) or poorly controlled steroid-induced diabetes mellitus (glycosolated hemoglobin > 8%)

Heilung bei fortgeschrittenem Darmkrebs

Die Fortschritte in der Diagnostik und Therapie der kolorektalen Karzinome (CRC) haben in den vergangenen 10 Jahren zu einer kontinuierlichen Abnahme der Sterblichkeit geführt. Unter dem Begriff Kolorektalkarzinom werden Dickdarm -, Rektum- und Analkarzinom zusammengefasst und auch im Krebsregister gemeinsam erfasst. Es gibt sowohl eine Leitlinie Kolorektales Karzinom (1) als auch separate Onkopedia-Leitlinienempfehlungen für das Kolonkarzinom (2) und das Rektumkarzinom (3).

Arzttermine aus Furcht vor dem Coronavirus auf die lange Bank schieben? Davon rät der Krebsinformationsdienst des Deutschen Krebsforschungszentrums ab. Symptome und Schmerzen sollten ernst genommen und vom Arzt abgeklärt werden. In den meisten Fällen wird es sich nicht um eine schwerwiegende Erkrankung wie Krebs handeln. Wenn aber doch, dann ist es besser, sie möglichst früh zu erkennen und, wenn nötig, sofort zu behandeln – dies erhöht die...
