Findings from Research

In a study of 1,010 breast cancer patients, hypofractionated radiotherapy (HFRT) showed similar locoregional recurrence-free survival (LRRFS) and disease-free survival (DFS) rates compared to conventionally fractionated radiotherapy (CFRT) after a median follow-up of 49.5 months.

While HFRT was effective across various nodal stages and molecular subtypes, it tended to show lower DFS in N2-3 patients with triple-negative breast cancer compared to CFRT, indicating a need for further investigation in this specific group.

Hypofractionated whole breast irradiation (WBI) has been shown to produce outcomes comparable to conventional radiation in early-stage breast cancer patients, suggesting it is a safe and effective treatment option.

Current trials, including a phase III study by the Radiation Therapy Oncology Group, are investigating the feasibility and effectiveness of adding a concurrent tumor bed boost to hypofractionated WBI, which may enhance treatment outcomes and broaden its use.

Hypofractionated radiotherapy is gaining importance in breast cancer treatment, suggesting a shift towards more efficient radiation delivery methods.

The introduction of simultaneous integrated boost techniques allows for targeted treatment of the primary tumor region, potentially improving treatment outcomes for patients.

Hypofractionated radiation therapy, which delivers fewer but larger doses of radiation over a shorter period, has shown comparable outcomes to conventional radiation in treating breast cancer, suggesting it could be an effective alternative.

Ongoing phase 3 trials are investigating hypofractionated whole breast irradiation and accelerated partial breast irradiation, which may lead to broader acceptance of these methods for early-stage breast cancer, although concerns about patient selection and late toxicity remain.

Hypofractionated radiation therapy in the treatment of early-stage breast cancer. Freedman, GM.[2021]

Recent advancements in radiation therapy for non-metastatic breast cancer, particularly hypofractionation and partial breast irradiation, have led to optimized treatment approaches that consider both patient and tumor characteristics.

Despite strong level-1 evidence supporting hypofractionation, its adoption in routine practice has been slow, prompting the AIRO Breast Cancer Group to issue position statements aimed at standardizing postoperative radiation therapy practices based on current evidence.

In a study of 2309 breast cancer patients, those receiving hypofractionated radiotherapy experienced significantly less acute skin reactions and pain compared to those receiving conventional fractionation, indicating a safer treatment option.

Hypofractionation also resulted in lower levels of patient-reported symptoms like burning, swelling, and fatigue during treatment, suggesting it may enhance patient comfort without compromising long-term outcomes.

In a study of 81 patients with localized breast cancer treated with hypofractionated radiotherapy (HFRT), the treatment was well-tolerated, with low rates of late toxicities such as chest pain (11%) and limb pain (12%).

The five-year overall survival rate was 76.5%, and there were no locoregional recurrences, indicating that HFRT is effective in controlling the disease while minimizing side effects.

In a study involving 396 patients treated with ultra-hypofractionated breast radiotherapy, the five-year local-relapse free survival (LRFS) rate was an impressive 98.8%, indicating high efficacy in controlling breast cancer.

While ultra-hypofractionated radiotherapy showed excellent tumor control, certain regimens, particularly the 5.7 Gy weekly fraction and tumor bed boost, were linked to a higher risk of acute and late skin toxicities, highlighting the need for careful treatment planning.

In a study of 39 breast cancer patients treated with an accelerated hypofractionated radiotherapy schedule, no significant lung toxicity or adverse effects were observed after a median follow-up of 43 months, indicating the treatment's safety.

The radiotherapy regimen (34 Gy in 10 fractions plus an 8 Gy boost) was well-tolerated, with only minor skin changes noted in a few patients, suggesting it is a feasible option for adjuvant treatment without significant long-term side effects.

Hypofractionated radiotherapy is gaining popularity for breast cancer treatment in the UK and Canada, but there are concerns about potential increased toxicity associated with this approach.

The article emphasizes the importance of careful planning and dosimetry in hypofractionated radiotherapy to ensure effective treatment while minimizing risks, and it provides recommendations for both planning and monitoring during treatment.

In a study involving 92 patients undergoing post-mastectomy radiation therapy (PMRT) with a hypofractionated regimen of 43.5 Gy over 15 days, the majority experienced mild skin toxicities, with 62% developing grade 2 dermatitis, which mostly resolved within three months.

The hypofractionated approach demonstrated a low incidence of significant acute toxicities, while effectively covering the target areas, although it resulted in a slightly higher dose to the ipsilateral lung compared to the heart.

Hypofractionation for whole-breast irradiation is safe and effective, providing similar local control and cosmetic outcomes compared to traditional methods, as supported by recent randomized trials.

There is growing interest in using hypofractionation for partial-breast irradiation, with early studies showing promising local control and manageable side effects, while larger randomized trials are currently being conducted to further evaluate its efficacy.
