Is less than mastectomy a safe option?

Area of Science:

• Oncology
• Surgical Oncology
• Breast Cancer Research

Background:

• Historically, ablative surgery with or without radiotherapy offered limited cure rates (0-30%) for early-stage breast cancer.
• This limited efficacy challenges the notion that deviating from specific local treatments significantly compromises a patient's cure potential.

Purpose of the Study:

• To review the curability of breast cancer and evaluate the safety and efficacy of breast-conserving techniques compared to mastectomy.
• To challenge the rigid application of total mastectomy recommendations and advocate for informed patient consent regarding treatment alternatives.

Main Methods:

• Review of data from two clinical trials and numerous uncontrolled studies.
• Analysis of outcomes for breast cancer patients treated with ablative surgery versus breast-conserving techniques.

Main Results:

• Breast conservation is feasible in up to 90% of patients with acceptable cosmetic outcomes and a low salvage mastectomy rate (10-15% at 10 years).
• These techniques are safe for tumors up to 5 cm, regardless of palpable lymph nodes, with survival and local recurrence rates comparable to radical surgery.
• Existing data do not support claims that alternative treatments increase recurrence or mortality risk.

Conclusions:

• Rigid adherence to total mastectomy is not justified based on current evidence.
• Strict criteria for tumor size or lymph node palpability are illogical limitations for breast conservation.
• Informed patient consent requires a thorough discussion of all safe treatment alternatives, including breast conservation.
