Regional Lymph Node Radiotherapy in Breast Cancer: Single Anterior Supraclavicular Field vs. Two Anterior and Posterior Opposed Supraclavicular Fields

Attique Anwer, Ahmed Ijaz, Muhammad Arshad

ABSTRACT

Objective: To compare different alternatives for the two regional Auxiliary lymph node (AXLN) and Supraclavicular lympnode (SCLNs) treatment programs by providing a perfect balance of homogeneity and by arranging target volume coverage.
Study Design: Cross sectional.
Place and Duration of Study: The study was conducted from 11th March 2020 to 11th September 2020 at the oncology ward of the Tertiary Care Hospital, Multan.
Materials and Methods: Forty breast cancer patients were included in the study. A three-dimensional (3D) planning system and a 6MV Compact machine technique were planned for the patients with breast cancer treated with post-surgery radiation that included the SC field.
Results: The minimum weight of these patients was 40kg, maximum 110kg. The minimum height was 148cm, the highest 175cm. Measurements averaged 63.5kg and 163.5cm respectively. The depth of the SC was 3-7 cm whereas the diameter of the chest wall was 12-21 cm. Body mass index has a relation with the mean of both the diameter of the chest wall and SC depth.
Conclusion: Two anterior and posterior opposed supraclavicular field is a better choice for the treatment as compared to single anterior supraclavicular fields. Several hot spots were produced at the two anterior and posterior opposed supraclavicular fields due to the use of single-photon.

Key Words: AXLN, Body Mass Index, Radiotherapy Supraclavicular, SCLNs.
