Helical Tomotherapy for Postmastectomy Radiotherapy after Immediate Left Breast Reconstruction: A Case Study
نویسندگان
چکیده
A 43-year-old premenopausal female presented with a multicentric infiltrating lobular carcinoma of the left breast with axillary nodes metastasis. She underwent modified radical mastectomy with axillary lymph node dissection (level I and II) followed by a mixed autologous latissimus dorsi flap reconstruction with the addition of prosthesis. The final pathological analysis revealed a 6 cm invasive lobular carcinoma pT3N2aM0, grade III/III, estrogen and progesterone positive, human epidermal growth factor receptor 2 (HER2) negative, with 5/16 positive lymph nodes. She received neoadjuvant chemotherapy with doxorubicin and cyclophosphamide followed by paclitaxel. Post-mastectomy radiotherapy with axillary, supraclavicular and internal mammary lymph nodes (IMLN) irradiation was delivered to a dose of 50 Gy/25 fx. In this case with multiple risk factors for radiation-induced cardiac toxicity (left-sided lesion, internal mammary lymph nodes (IMLN) irradiation), we discuss the role of helical tomotherapy as a treatment alternative to conventional tangential radiotherapy.

The effects of postmastectomy adjuvant radiotherapy on immediate two-stage prosthetic breast reconstruction: a systematic review.
BACKGROUND The authors performed a systematic review of the literature on the outcome of therapy for patients with breast cancer who underwent adjuvant radiotherapy after an immediate two-stage prosthetic breast reconstruction, either following tissue expansion (stage 1) or after removal of the tissue expander and insertion of a final breast implant (stage 2). Their outcomes were compared to th...
متن کاملThe impact of immediate breast reconstruction on the technical delivery of postmastectomy radiotherapy.
PURPOSE To quantify the impact of immediate breast reconstruction on postmastectomy radiation therapy (PMRT) planning. METHODS A total of 110 patients (112 treatment plans) who had mastectomy with immediate reconstruction followed by radiotherapy were compared with contemporaneous stage-matched patients who had undergone mastectomy without intervening reconstruction. A scoring system was used...
متن کاملCost-Effectiveness Analysis of Breast Reconstruction Options in the Setting of Postmastectomy Radiotherapy Using the BREAST-Q.
BACKGROUND A consensus is lacking on a uniform reconstructive algorithm for patients with locally advanced breast cancer who require postmastectomy radiotherapy. Both delayed autologous and immediate prosthetic techniques have inherent advantages and complications. The study hypothesis is that implants are more cost effective than autologous reconstruction in the setting of postmastectomy radio...

Background: Radiation Pneumonia (RP) is one of the most extensive side effects in Stereotactic Body Radiotherapy (SBRT) of lung cancer. SBRT are performed by means of Intensity Modulated Radiotherapy (IMRT), Intensity Modulated Arc Therapy (IMAT), CyberKnife (CK) or Helical Tomotherapy (HT) treatment methods. In this study, we performed a plan study to determine the plan parameter such as the M...
