Seco-Steroids C07C)
CPC - C07J - 2021.08 C07J STEROIDS (seco-steroids C07C) Definition statement This place covers: Compounds containing a cyclopenta[a]hydrophenanthrene skeleton (see below) or a ring structure derived therefrom: • by contraction or expansion of one ring by one or two atoms; • by contraction or expansion of two rings each by one atom; • by contraction of one ring by one atom and expansion of one ring by one atom; • by substitution of one or two carbon atoms of the cyclopenta[a]hydrophenanthrene skeleton, which are not shared by rings, by hetero atoms, in combination with the above defined contraction or expansion or not, or; • by condensation with carbocyclic or heterocyclic rings in combination with one or more of the foregoing alterations or not. Preparation of steroids including purification, separation, stabilisation or use of additives unless provided for elsewhere, as specified below. Treatment and modification of steroids provided that • the treatment is not provided for elsewhere and • the resultant product is a compound under the subclass definition. Relationships with other classification places In class C07, in the absence of an indication to the contrary, a compound is classified in the last appropriate place, i.e. in the last appropriate subclass. For example cyclopenta [a] hydrophenantrenes are classified in subclass C07J as steroids and not in subclasses C07C or C07D as carbocyclic or heterocyclic compounds. Subclass C07J is a function-oriented entry for the compounds themselves and does not cover the application or use of the compounds under the subclass definition. For classifying such information other entries in the IPC exist, for example: Subclass A01N: Preservation of bodies of humans or animals or plants or parts thereof; biocides, e.g. -

Li1,3 Abstract Background: Evidence suggests that recent oral contraceptive (OC) use is associated with a small increased breast cancer risk; yet risks associated with contemporary OC preparations and by molecular subtype are not well characterized. Methods: We conducted a population-based case–control study of invasive breast cancer among women ages 20 to 44 residing in the Seattle–Puget Sound area from 2004 to 2010 (985 cases and 882 controls). We collected information on contraceptive use and participant characteristics via an in-person interview. Mul- tivariable-adjusted logistic regression was used to calculate odds ratios (OR) and 95% confidence intervals (CI). Results: Lifetime duration of OC use for 15 years was associated with an increased breast cancer risk (OR, 1.5; 95% CI, 1.1–2.2). Current OC use (within 1 year of reference date) for 5 years was associated with an increased risk (OR, 1.6; 95% CI, 1.1–2.5) and there were no statistically significant differences in risk by OC preparation. Risk magnitudes were generally greater among women ages 20 to 39, and for estrogen receptor– À À negative (ER ) and triple-negative breast cancer (current use for 5 years among ages 20–39: ER OR, 3.5; 95% CI, 1.3–9.0; triple-negative OR, 3.7; 95% CI, 1.2–11.8), although differences between groups were not statistically significant. -
