Hospital Course:

This is a discharge summary for a 66-year-old female with infiltrating ductal cancer in the lower outer quadrant of her left breast. The patient underwent left partial mastectomy and sentinel node biopsy. The patient also had bilateral lung masses that were proven to be positron emission tomography (PET) fludeoxyglucose avid. Transthoracic core biopsy of the lung lesions revealed adenocarcinoma acinar type. The case was discussed at the multidisciplinary tumour board, and histology suggested three distinct curable primaries: T1N1 breast cancer and bilateral T1N0 lung cancers. The breast cancer was managed with partial mastectomy with sentinel node sampling, adjuvant tangential whole breast irradiation (WBI) with regional nodal irradiation (RNI), and an aromatase inhibitor (letrozole). The bilateral lung primaries were treated with stereotactic ablative radiotherapy (SABR). The left and right lung tumors were each treated with 48 Gy in 4 fractions prescribed to the isocenter of each lung lesion, using SABR with volumetric modulated arc therapy technique. The breast and regional nodes (supraclavicular and axilla levels I, II and III) were treated to 50 Gy in 25 fractions using a field-in-field technique in a four-field beam arrangement. All three sites were treated concurrently. The patient completed all her treatments without toxicity.

The patient developed dyspnoea and cough 5 weeks post lung radiotherapy and within 1 week of completing breast radiotherapy. She did not feel her symptoms warranted therapy, and given her diabetic history, steroids were withheld. Her CT scan was consistent with post-radiotherapy changes. Pulmonary function tests showed mild restrictive defect.

The patient was discharged home in a stable condition and without any complications. Follow-up appointments were scheduled as appropriate.

Diagnoses:
