Study: Breast-conserving surgery offers better survival than mastectomy for cancer

Women who undergo breast-conserving surgery and radiation therapy for breast cancer are more likely to survive the disease than those who receive a full mastectomy, a study published Wednesday by JAMA Surgery found.

We describe a multicentre, randomized controlled trial recruiting patients at large academic centres across India. Patients without distant metastases who merit adjuvant radiotherapy will be eligible for inclusion in the study. Patients in the control arm will receive adjuvant radiotherapy to the breast or chest wall (with/without regional nodes) to a dose of 40  Gy/15 fractions/3 weeks, while those in the experimental arm will receive a dose of 26 Gy/5 fractions/1 week (to the same volume). The use of a simultaneous integrated boost (dose of 8 Gy and 6 Gy, respectively) is allowed...

The role of radiation therapy in early breast cancer has emerged after two randomized trials that reported there was no significant difference in survival between total mastectomy and breast conserving surgery plus radiation therapy [1,2]. There was a significant decrease of the local recurrence rate in the ipsilateral breast after lumpectomy plus breast irradiation, as compared to lumpectomy alone [1]. In a prospective study in Europe (EORTC 22881-10882), postoperative whole breast irradiation with tumor bed boost significantly improved the 10-year local recurrence rate compared to whole breast irradiation alone in early breast cancer [3].

Post Mastectomy Radiation Treatment (PMRT) is an important component of the multidisciplinary management of local advanced breast cancer patients. Hypofractionation has become the new standard of care after breast conserving surgery but has not been yet adopted in the setting of post mastectomy radiation (PMRT) in most countries.

Authors: Omranipour R Abstract Surgery in the form of both mastectomy and breast conservation is the main step in the treatment of breast cancer. Numerous studies have shown an equivalent long-term survival for breast conserving surgery (BCS) and mastectomy . Patients desire and tumor characteristics, especially size and multicentricity, are the key factors that affect the decision between these two types of surgery . Patients with any contraindication for radiotherapy or previous history of radiation to the breast field are not suitable for BCS . There are few absolute contraindications for BCS , and early pr...

ConclusionsPatient preference is difficult to define and measure, and heterogeneity across studies renders direct comparison difficult. Future work is needed to define women ’s risk-thresholds for certain treatments, delve into the psychological factors that direct their decisions, and understand how patients’ valuations of risk interact with society’s.

Clinical trials support adjuvant regional nodal irradiation (RNI) after breast conserving surgery (BCS) or mastectomy for patients with lymph node-positive breast cancer. Advanced treatment planning techniques (e.g., intensity-modulated radiation therapy [IMRT]) may reduce dose to organs-at-risk (OARs) in this situation. Yet, uncertainty persists about when IMRT is clinically indicated (versus 3D conformal radiation, 3DCRT) for RNI. We hypothesized that an adaptive treatment planning algorithm (adaptive-TPA) for IMRT adoption would allow OAR constraints for RNI to be met when 3DCRT could not without significantly changing ...

Several decades ago, the concept of deintensification of breast cancer treatment began with randomized trials demonstrating breast conservation therapy (BCT) was equivalent to mastectomy with respect to recurrence and survival and optimized functional outcomes and quality of life. Radiation therapy (RT) has remained a mainstay of BCT, traditionally defined as lumpectomy followed by adjuvant RT and hormone therapy (in estrogen receptor –positive patients). The rationale for incorporating adjuvant radiation is the ability to eliminate microscopic disease after lumpectomy that could otherwise manifest as a local recurre...

Conclusion: OS did not differ between the 2 groups in early breast cancer patients with 1 or 2 metastatic axillary lymph nodes who underwent TM. Omission of ALND may be considered in selected patients. PMID: 32528907 [PubMed]

Abstract PURPOSE: To develop recommendations for management of patients with breast cancer (BC) with germline mutations in BC susceptibility genes. METHODS: The American Society of Clinical Oncology, American Society for Radiation Oncology, and Society of Surgical Oncology convened an Expert Panel to develop recommendations based on a systematic review of the literature and a formal consensus process. RESULTS: Fifty-eight articles met eligibility criteria and formed the evidentiary basis for the local therapy recommendations; six randomized controlled trials of systemic therapy met eligibility criteria. ...
