Prospective results of concurrent radiation therapy and weekly paclitaxel as salvage therapy for unresectable locoregionally recurrent breast cancer

Primary Chemoradiotherapy Treatment (PCRT) for HER2+ and Triple Negative Breast Cancer Patients: A Feasible Combination

Primary systemic treatment (PST) downsizes the tumor and improves pathological response. The aim of this study is to analyze the feasibility and tolerance of primary concurrent radio−chemotherapy (PCRT) in breast cancer patients. Patients with localized TN/HER2+ tumors were enrolled in this prospective study. Radiation was delivered concomitantly during the first 3 weeks of chemotherapy, and it was based on a 15 fractions scheme, 40.5 Gy/2.7 Gy per fraction to whole breast and nodal levels I-IV. Chemotherapy (CT) was based on Pertuzumab−Trastuzumab−Paclitaxel followed by anthracyclines in HER2+ and CBDCA-Paclitaxel followed by anthracyclines in TN breast cancers patients. A total of 58 patients were enrolled; 25 patients (43%) were TN and 33 patients HER2+ (57%). With a median follow-up of 24.2 months, 56 patients completed PCRT and surgery. A total of 35 patients (87.5%) achieved >90% loss of invasive carcinoma cells in the surgical specimen. The 70.8% and the 53.1% of patients with TN and HER-2+ subtype, respectively, achieved complete pathological response (pCR). This is the first study of concurrent neoadjuvant treatment in breast cancer in which three strategies were applied simultaneously: fractionation of RT (radiotherapy) in 15 sessions, adjustment of CT to tumor phenotype and local planning by PET. The pCR rates are encouraging.

Factors influencing psychological distress and effects of stepwise psychological care on quality of life in patients undergoing chemotherapy after breast cancer surgery

OBJECTIVE

To investigate factors influencing psychological distress and the effect of stepwise psychological care on the quality of life in patients undergoing chemotherapy after breast cancer surgery.

METHODS

A retrospective study was conducted on 96 patients undergoing chemotherapy after breast cancer surgery. The patients were evenly divided into a routine care group (control group) and a stepwise psychological care group (observation group) according to the care method. The correlation between the psychological distress and the Self-Rating Anxiety Scale (SAS) score was investigated. The impact of care intervention on the psychological distress, SAS score, and the quality of life of patients before and after intervention were explored. Relevant factors that affect the psychological distress of patients undergoing chemotherapy after breast cancer surgery were also investigated.

RESULTS

A univariate analysis showed that age, residence, monthly income, education level, medical insurance status, occupation, surgery method, and anxiety score all contributed to the degree of psychological distress in patients with breast cancer mastectomy (all P<0.05). A multivariate regression analysis demonstrated that young age, low monthly income, no medical insurance, mastectomy, and high SAS score were risk factors for the psychological distress of patients who underwent mastectomy (all P<0.05). The psychological distress was positively correlated with anxiety scores of patients undergoing chemotherapy after breast cancer surgery (r=0.249, P=0.005). Both psychological distress and anxiety scores of the observation group after stepwise psychological care were significantly lower than those before treatment and those of the control group (both P<0.05). After treatment, both groups of patients showed better scores in additional concerning items, social/family well-being, functional well-being, physical well-being, emotional well-being, and overall quality of life than before treatment (all P<0.05). Of note, the observation group demonstrated better quality of life than that of the control group.

CONCLUSION

Age, low monthly income, radical mastectomy, and no medical insurance prior to undergoing chemotherapy after breast cancer surgery are independent factors that affect psychological distress. The distress was positively correlated with anxiety. Thus, stepwise psychological care may alleviate patients' psychological distress and anxiety.

Recent advances in radiotherapy of breast cancer

Radiation therapy is an integral part of the multidisciplinary management of breast cancer. Regional lymph node irradiation in younger trials seems to provide superior target coverage as well as a reduction in long-term toxicity resulting in a small benefit in the overall survival rate. For partial breast irradiation there are now two large trials available which support the role of partial breast irradiation in low risk breast cancer patients. Multiple randomized trials have established that a sequentially applied dose to the tumor bed improves local control with the cost of worse cosmetic results.
