7 Strategies to reduce arm and shoulder problems

What is the most effective and cost-effective way of delivering the intervention (for example, type of physiotherapy or exercise, mode of delivery, number of sessions) to reduce arm and shoulder problems after breast cancer surgery or radiotherapy, and what is the acceptability of the intervention for different groups, such as:

  • women, men, trans people and non-binary people

  • people from minority ethnic family backgrounds

  • people with learning disabilities or cognitive impairment, or physical disabilities, or both

  • neurodiverse people? [2023]

For a short explanation of why the committee made the recommendation for research, see the rationale section on arm and shoulder mobility.

Full details of the evidence and the committee's discussion are in evidence review L: strategies for reducing arm and shoulder problems after breast cancer surgery or radiotherapy.

8 Adherence and satisfaction for interventions to reduce arm and shoulder problems

What is the adherence to, and satisfaction with, different intervention formats (for example, individual, group, virtual, and face to face) to reduce arm and shoulder problems after breast cancer surgery or radiotherapy, and what is the impact of greater adherence on effectiveness for different groups, such as:

  • women, men, trans people and non-binary people

  • people from minority ethnic family backgrounds

  • people with learning disabilities or cognitive impairment, or physical disabilities, or both

  • neurodiverse people? [2023]

For a short explanation of why the committee made the recommendation for research, see the rationale section on arm and shoulder mobility.

Full details of the evidence and the committee's discussion are in evidence review L: strategies for reducing arm and shoulder problems after breast cancer surgery or radiotherapy.

9 Effectiveness of 26 Gy in 5 fractions over 1 week regimen in people receiving breast reconstruction

What is the effectiveness of radiotherapy given in 26 Gy in 5 fractions over 1 week compared with 40 Gy in 15 fractions over 3 weeks in people with early or locally advanced invasive breast cancer who are offered breast reconstruction? [2023]

For a short explanation of why the committee made the recommendation for research, see the rationale section on dose fractionation of external beam radiotherapy.

Full details of the evidence and the committee's discussion are in evidence review M: effectiveness of different external beam hypofractionation radiotherapy regimens in people with early-stage or locally advanced invasive breast cancer.

10 Effectiveness of 26 Gy in 5 fractions over 1 week regimen in people receiving nodal irradiation

What is the effectiveness of radiotherapy given in 26 Gy in 5 fractions over 1 week compared with 40 Gy in 15 fractions over 3 weeks in people with early or locally advanced invasive breast cancer who are also offered nodal irradiation? [2023]

For a short explanation of why the committee made the recommendation for research, see the rationale section on dose fractionation of external beam radiotherapy.

Full details of the evidence and the committee's discussion are in evidence review M: effectiveness of different external beam hypofractionation radiotherapy regimens in people with early-stage or locally advanced invasive breast cancer.
