Difficulty: MediumMenstrual Cycle Abnormalities and Contraception

Match each patient's clinical profile with the most appropriate contraceptive method based on the World Health Organization Medical Eligibility Criteria (WHO MEC) and non-contraceptive benefits.

  • A 33-year-old woman with a history of estrogen-receptor positive breast cancer treated successfully 2 years ago, seeking a highly effective, long-acting contraceptive.Copper intrauterine device
  • A 37-year-old woman who smokes a pack of cigarettes daily and requests a convenient contraceptive method, but strongly prefers not to have a device placed in her uterus.Etonogestrel implant
  • A 26-year-old woman with a history of unprovoked deep vein thrombosis who suffers from heavy menstrual bleeding and dysmenorrhea.Levonorgestrel-releasing intrauterine device
  • A 22-year-old woman with moderate acne, hirsutism, and irregular, infrequent menses seeking contraception and symptom management.Combined oral contraceptive pills

Answer

Patient 1 (breast cancer history) matches with the Copper intrauterine device. Patient 2 (smoker over 35 refusing IUD) matches with the Etonogestrel implant. Patient 3 (history of DVT with heavy menses) matches with the Levonorgestrel-releasing intrauterine device. Patient 4 (hyperandrogenism and irregular menses) matches with Combined oral contraceptive pills.
Each correct match strictly adheres to the WHO MEC guidelines while maximizing non-contraceptive benefits. All hormonal methods are absolutely contraindicated in active or recent breast cancer (MEC 4), requiring the hormone-free copper IUD. Estrogen is contraindicated in smokers over 35 and patients with a history of DVT (MEC 4), necessitating progestin-only methods; the etonogestrel implant respects the smoker's preference to avoid IUDs, while the levonorgestrel IUD provides targeted treatment for the DVT patient's heavy menstrual bleeding. Finally, combined oral contraceptives are the preferred first-line therapy for managing the hyperandrogenism and cycle irregularity characteristic of suspected polycystic ovary syndrome.

Step-by-Step Solution

1
Analyze each patient's medical history for absolute contraindications to estrogen.
Breast cancer, smoking over age 35, and a history of unprovoked deep vein thrombosis are all absolute contraindications (MEC Category 4) to estrogen-containing methods.
Identifying estrogen contraindications immediately eliminates combined hormonal methods for three of the four patients.
2
Evaluate absolute contraindications to progestin.
A history of breast cancer is also a Category 4 contraindication to progestin-only methods. Therefore, the patient with breast cancer must receive a hormone-free method.
Hormone-dependent cancers preclude the use of any exogenous hormonal contraception.
3
Match the remaining patients with the most appropriate method based on their specific preferences and needed non-contraceptive benefits.
The smoker over 35 refuses IUDs, making the progestin-only implant the best choice. The patient with a history of DVT has heavy bleeding, making the levonorgestrel IUD ideal for targeted symptom relief. The patient with suspected PCOS needs androgen suppression, making combined oral contraceptives optimal.
Tailoring contraception requires balancing patient safety, individual preferences, and the ability of certain methods to manage comorbid symptoms.

Key Concept
