Oncoplastic breast surgery versus conventional breast conserving surgery - a prospective follow-up study of subjective loco-regional late morbidity.

Background and aim: Few studies have focused on the symptoms of loco-regional morbidity in shoulders, arms, and breasts related to oncoplastic breast surgery (OPS). This study aimed to determine if a difference exists in the prevalence or variety of subjective symptoms of shoulder, arm, and breast morbidity in patients undergoing OPS compared with patients receiving conventional breast conserving surgery (C-BCS). Cosmetic result and body image were included as secondary endpoints.Methods: This prospective follow-up study with 18 months of questionnaire-based follow-up included women with breast cancer or ductal carcinoma in situ. They were divided into two groups - C-BCS or OPS - depending on type of surgery performed. Furthermore, patient, disease, and treatment characteristics were recorded.Results: Among 334 completers, 229 (69%) received C-BCS and 105 (31%) received OPS. Participants were comparable regarding age, comorbidity, BMI, re-excision rate (15-16%), and axillary surgery. As for tumor characteristics, a more advanced disease stage was shown in the OPS than in the C-BCS group with larger tumor and lumpectomy size, more multifocality, and the corresponding following systemic adjuvant therapy.The questionnaire revealed that the two groups were comparable with no significant differences in frequency or variety of symptoms of shoulder and arm morbidity. Overall, participants were highly satisfied with the cosmetic results in both groups and no significant inter-group differences were observed.Conclusion: In patients with larger tumors, breast conserving surgery utilizing oncoplastic techniques yields results regarding subjective shoulder, arm, and breast morbidity as well as cosmetic outcome comparable with those of C-BCS performed on smaller tumors.Trial registration: ClinicalTrials.gov, registration number: NCT02159274 (2014).HIGHLIGHTSSubjective symptoms of shoulder, arm, and breast morbidity are comparable when oncoplastic breast surgery is compared to conventional breast conserving surgery.The variety of symptoms of shoulder and arm morbidity following oncoplastic surgery does not differ from symptoms following conventional breast conserving surgery.The cosmetic outcome following oncoplastic breast surgery is comparable to breast conserving surgery without oncoplastic techniques.

The Nordic SentiMag trial: a comparison of super paramagnetic iron oxide (SPIO) nanoparticles versus Tc(99) and patent blue in the detection of sentinel node (SN) in patients with breast cancer and a meta-analysis of earlier studies.

The aim of the study is to compare the efficacy of SPIO as a tracer in sentinel node biopsy (SNB) in breast cancer with Tc and patent blue in a multicentre prospective study and perform a meta-analysis of all published studies. It also aims to follow skin discoloration after SPIO injection and describe when and how it resolves. Totally 206 patients with early breast cancer were recruited. Tc and patent blue were administered in standard fashion. Patients were injected with SPIO (Sienna+) preoperatively. SNB was performed and detection rates were recorded for both methods. Skin discoloration was followed and documented postoperatively. Data extraction and subsequent meta-analysis of all previous studies were also performed. SN detection rates were similar between standard technique succeeded and SPIO both per patient (97.1 vs. 97.6 %, p = 0.76) as well as per node (91.3 vs. 93.3 %, p = 0.34), something which was not affected by the presence of malignancy. Concordance rates were also consistently high (98.0 % per patient and 95.9 % per node). Discoloring was present in 35.5 % of patients postoperatively, almost exclusively in breast conservation. It fades slowly and is still detectable in 8.6 % of patients after 15 months. Meta-analysis depicted similar detection rates (p = 0.71) and concordance rates (p = 0.82) per patient. However, it seems that SPIO is characterized by higher nodal retrieval (p < 0.001). SPIO is an effective method for the detection of SN in patients with breast cancer. It is comparable to the standard technique and seems to simplify logistics. Potential skin discoloration is something of consideration in patients planned for breast conservation.

Locally advanced breast cancer (stadium III-IV, T3-4) can involve the thoracic wall as well as larger skin areas. This may result in symptoms such as pain, malodorous wounds, and a reduced quality of life. In some selected cases a palliative surgical intervention may be indicated. This case story present two cases of locally advanced breast cancer which were managed surgically in a co-operation between thoracic, plastic and breast cancer surgeons. Both cases were preoperatively evaluated at a multidisciplinary team conference.

Use of bisphosphonates and risk of breast cancer.

A decreased risk of breast cancer has been reported among patients given bisphosphonates. The present aims were to study potential associations between different antiosteoporosis drugs, including bisphosphonates, and the risk of breast cancer before and after start of treatment and to appraise possible dose-effect relationships. From national Danish registers, all female users of bisphosphonates aged ≥40 years and other drugs against osteoporosis between 1996 and 2006 were identified (n = 87,104). This cohort was compared with a control group, where each patient was matched on age with three nonexposed women from the general population (n = 261,322). Before start of most drugs against osteoporosis an increased risk of breast cancer was seen compared to controls (e.g., adjusted OR = 1.09, 95% CI 1.04-1.16 for alendronate). This excess risk was higher in younger women (e.g., OR = 4.48, 95% CI 2.98-6.75 for alendronate in women ≤50 years) and disappeared in women older than 70 years (e.g., OR = 0.95, 95% CI 0.88-1.01 for alendronate). In contrast, a decreased risk of breast cancer was seen after start of alendronate (HR = 0.53, 95% CI 0.38-0.73), etidronate (HR = 0.80, 95% CI 0.73-0.89), and raloxifene (HR = 0.53, 95% CI 0.38-0.73). No dose-response relationship was present for alendronate and etidronate, whereas a decreasing risk was seen with increasing daily dose of raloxifene. Bisphosphonate treatment in women was associated with a reduced risk of breast cancer. However, no causal relationship seemed to be present.
