Metastases to the skeletal muscle from breast cancer represent an unusual and rare condition. We present the case of a 27-year-old female with left breast cancer (IDC NST G3) who underwent neoadjuvant chemotherapy followed by conservativesurgery (sectorectomy and lymphadenectomy) and radiation therapy. Two months after the end of radiotherapy she presented with a 2 mm skin lesion and she was referred for a screening ultrasound. The screening automated breast ultrasound (ABUS) revealed local recurrence and pectoralis metastases, lesions evaluated also by magnetic resonance imaging. The diagnosis was confirmed by the ultrasound-guided biopsy.

Abstract Background Decreased pectoralis minor muscle length is common after primary breast cancer treatment and can result in an abnormal position of the scapula. This position can contribute to shoulder pain and pathomechanics and can lead to problems such as impingement syndrome, rotator cuff tears, and frozen shoulder. Currently, there are limited reliable methods for measuring pectoralis minor length. Objective The objective of this study was to examine the reliability and validity of measuring pectoralis minor length in women diagnosed with breast cancer. Design This was a cross-sectional reliability and validity study. Methods Bilateral pectoralis minor length (in centimeters) was assessed using a palpation meter in women (N = 29) diagnosed with breast cancer by 2 licensed physical therapists who were masked to the measures. Bilateral pectoralis minor length was also measured using a motion capture system to assess validity. Results Intratester reliability (intraclass correlation coefficient, ICC [3,k] = 0.971; 95% confidence interval [CI] = 0.939–0.986; standard error of measurement [SEM] = 0.16 cm) and intertester reliability (ICC[3,k] = 0.915; 95% CI = 0.81–0.962; SEM = 0.31 cm) were excellent for the palpation meter on the affected side and the unaffected side (intratester reliability: ICC[3,k] = 0.951; 95% CI = 0.897–0.977; SEM = 0.19 cm; intertester reliability: ICC[3,k] = 0.945; 95% CI = 0.877–0.975; SEM = 0.22 cm). Significant correlations were found between the motion capture system and the palpation meter on the affected side (r = 0.87) and the unaffected side (r = 0.81). Bland-Altman plots between the palpation meter and the motion capture system demonstrated that all the measures fell within the limits of agreement. Limitations This study encountered possible errors with the accuracy of the motion capture system tracking because of the proximity of the markers and inherent volumetric restrictions. Conclusions The palpation meter is a reliable, valid, easily administered, and cost-effective tool for assessing pectoralis minor length in women with breast cancer.

e24069 Background: Chemotherapy is often followed by muscle mass loss which has been associated with frailty. We explored factors associated with change in pectoralis muscle mass after chemotherapy. We hypothesized greater muscle loss with time would be associated with poorer overall survival. Methods: We identified individuals with breast cancer (N = 221), sarcoma (N = 115), and lymphoma (N = 216) who received chemotherapy at the University of Minnesota MHealth Fairview and had CT scans before and after chemotherapy. Right pectoralis muscle area was measured using CORESLICER and indexed to body surface (right pectoralis muscle area [cm2] / body surface [m2]). We calculated quartiles of the indexed pectoralis measure. We restricted our analyses to participants who received a follow-up CT within two years after starting chemotherapy. In a multivariate linear regression, we explored associations of sex, age, BMI, ever-smoking, time since start of chemotherapy, indexed baseline muscle area, stage, type of diagnosis, and cumulative anthracycline dose with relative (%) change in muscle area. In a Cox regression we tested the association of relative muscle change with overall mortality. We used cubic splines to test for nonlinear effects. Results: Of 477 participants (66% female; mean age 61.3 (10.1) years), 366 received anthracyclines, 61 Trastuzumab, and 60 both. The average loss in right pectoral muscle area was -10% for women and -12% for men. We detected nonlinear effects of indexed baseline muscle area, P = 0.03. In a model using quartiles of indexed baseline muscle area, significant predictors of muscle loss included sex (women vs. men, -9.0%, 95% confidence interval (CI) -14.2- -3.7%, P = 0.0008), larger indexed baseline muscle area (quartiles 2, 3, 4 compared with quartile 1, change range -7 - -24%, 95% CI range, -2 - -30%, P-range < 0.0001 – 0.006), smoking (ever vs. never, -4.1%, 95% CI -7.6 - -0.7%, P = 0.02), and diagnosis (sarcoma vs breast cancer, -5.7%, 95% CI -11.1 - -0.3%, P = 0.04). There was no significant association between muscle change and overall survival (median follow-up time 4.1). Conclusions: Being female, larger baseline muscle mass (per m2 body surface), ever-smoking, and a sarcoma diagnosis were associated with greater relative muscle loss after chemotherapy. More data is needed to understand the course of sarcopenia in terms of recovery and survivorship. [Table: see text]

Research background. Breast cancer is the most common female malignancy. Different types of surgery are performed after assessing stage of the disease, tumour morphology, and other dimensions. Dysfunction of hand after surgery may affect physical, emotional and sexual function and quality of life more than body shape changes (Guan et al., 2012). The aim of this study was to evaluate the quality of life, shoulder range of motion, arm pain, circumference of arm, and hand muscle strength after breastconserving surgery after mastectomy. Methods. The study included 30 women, 15 of them were after breast conserving surgery, and 15 – after mastectomy. All subjects participated in the same physiotherapy program ‒ stretching and muscle strengthening exercises, shoulder girdle, neck and hand massage, lymph drainage massage (sleeve), transcutaneous electrical nerve stimulation (TENS). Duration of rehabilitation was two weeks. Quality of life, shoulder range of motion, arm pain and circumference, hand muscle strength of the affected side were measured before and after rehabilitation. Results. Regardless of the type of surgical intervention, the range of motion of shoulder flexion, extension and abduction in both groups after physiotherapy increased signifcantly, but for the patients who had undergone breast conserving surgery the ranges of motion were signifcantly higher (flexion – 163.20 ± 11,7°; extension – 48.53 ± 5.5°; abduction – 145.27 ± 13.6°) than for those who undergone mastectomy (flexion – 141.20 ± 13.2°; extension – 33.13 ± 4.9°; abduction – 130.33 ± 14.9°). It was found that circumference of the arm reduced significantly  in both groups, but comparing one group to another no signifcant differences were found. Pain intensity after physiotherapy in patients with mastectomy and patients who had undergone breast conserving surgery signifcantly decreased, but pain reduction was signifcantly higher in patients after breast conserving surgery (6.00 ± 1.1 points) compared to mastectomy group (3.67 ± 1.5 points). Muscle strength of hand of the affected side after physiotherapy increased signifcantly in both groups, but signifcantly more (up to 15.03 ± 2.1 kg) in patients after the breast conserving surgery compared to patients who had undergone mastectomy (up to 12.77 ± 2.0 kg). In addition, most of the functions of quality of life in patients who had undergone breast conserving surgery were signifcantly better than those in patients who had undergone mastectomy. Conclusions: 1. Regardless of the surgery type, shoulder range of motion and hand muscle strength increased signifcantly, and arm circumference and the pain reduced signifcantly after physiotherapy. 2. Shoulder range of motion and hand strength of the affected side were signifcantly higher while pain was signifcantly lower in patients who had undergone breast-conserving surgery compared to patients who had undergone mastectomy. 3. three components of the quality of life ‒ role, emotional and social functions – were signifcantly higher, but symptom scale scores were better in patients who had undergone breast-conserving surgery compared to those who had undergone mastectomy.Keywords: physiotherapy, breast cancer, mastectomy, breast-conserving surgery

  El presente estudio tiene como objetivo evaluar la funcionalidad de miembro superior, síntomas de fatiga y nivel de actividad física en mujeres post operatorio de cáncer de mama, grupo PO, en comparación a un grupo control de mujeres sanas. La funcionalidad de la extremidad superior se evaluó mediante el rango de movimiento (ROM) de flexión, abducción y rotación externa del hombro utilizando un inclinómetro digital; fuerza de prensión con un dinamómetro y discapacidad del miembro superior con el cuestionario Disabilities of the arm, shoulder and hand. La fatiga se evaluó con el Inventario Breve de Fatiga y el nivel de actividad física con el Cuestionario Internacional de Actividad Física. Treinta y cuatro mujeres (n=17, grupo PO; n=17, grupo control, GC) fueron evaluadas. El grupo PO presentó menor ROM del hombro y fuerza de prensión (diferencia de rango: 22,9°-22,9°; 5,6kgF, respectivamente) en comparación con el GC; el lado afectado presentó menor ROM del hombro en comparación con el lado no afectado (15°-21°). También hubo una mayor discapacidad en el lado afectado y un menor nivel de actividad física en el grupo PO. No hubo diferencias en la fatiga entre los grupos. Concluimos que el grupo PO presentó menor funcionalidad y un bajo nivel de actividad física en comparación con un grupo control. Abstract. This study aim to compare upper limb functionality, fatigue and physical activity level in women after breast cancer surgery in relation to a control group. Upper limb functionality was evaluated by mean of shoulder range of motion (ROM) of flexion, abduction and external rotation using a digital inclinometer; handgrip strength using a dynamometer and upper limb disability with the Disabilities of the arm, shoulder and hand questionnaire. Fatigue was assessed with the Brief Fatigue Inventory and physical activity level with the International Physical Activity Questionnaire. A thirty-four women (n=17, post-operated breast surgery group, PO; n=17, control group, CG) were recruited. PO group presented a decrease in both shoulder ROM and handgrip strength (range difference: 22.9°-22,9°; 5.6kgF, respectively) compared to CG; the affected side of the PO group presented with less shoulder ROM in comparison to the non-affected side (15°-21°). There was also greater disability on the affected side and a lower physical activity level in the PO group. There were no differences in the fatigue between the groups. We concluded that PO group presented with compromised functionality and low physical activity level compared to a control group.

Muscle Defect

Congenital pectoral muscle defects are very rare, and when accompanied by limb defects, they are called Poland syndrome. A woman in her 70s, 4 years after partial mastectomy for breast cancer, underwent mastectomy for a local recurrence. During the operation, the pectoralis major and minor muscles were found to be defective. However, the patient did not have any limb defects. Although congenital pectoral muscle defects are very rare, it would be better to confirm defects of the pectoral muscle by preoperative diagnostic imaging such as CT because the postoperative treatment may be affected.

Objectives: Defining the posterior extent of breast cancer prior to surgery has clinical implications. However, there are limited data available to guide the interpretation of breast cancers seen on MRI that abut the pectoralis muscle but lack associated muscle enhancement. Methods: In this retrospective study of breast MRIs performed between May 2008 and July 2019, 43 female patients demonstrated breast cancers abutting the pectoralis muscle without enhancement of the muscle itself. Imaging features of the cancers as well as pathologic and clinical outcomes were recorded. Statistical analyses of associations between imaging findings and clinical outcomes were performed using Fisher’s exact test, logistic regression, a Mann–Whitney U test and/or Student’s t-test. Results: The pectoralis major muscle was pathologically invaded by carcinoma in 4/43 (9.3%). There was no significant association between pectoralis muscle invasion and any MR imaging feature of the breast cancer. Tumors causing deformation of the muscle contour by MRI, tumors larger in size, tumors with a larger extent abutting the muscle and tumors in which the imaging feature abutting the muscle was a mass or non-mass enhancement (rather than a spicule) were more commonly seen in patients with muscle invasion, although these did not reach statistical significance (p > 0.05). Conclusion: In this study, a lack of pectoralis muscle enhancement by MRI did not exclude pathologic muscle invasion by breast cancers abutting the muscle. Advances in knowledge: Knowledge of the likelihood of pectoralis muscle involvement for breast cancers abutting the pectoralis muscle on MRI may guide accurate interpretation and definition of the posterior extent of disease.
