Introduction

Scarring is a natural result of wound healing. In some cases, however, there is formation of hypertrophic scars and keloids that are the result of collagen decomposition and synthesis [1, 2]. The cause of the formation of hypertrophic scars and keloids is not fully known. Some scars heal well, which leads to the formation of an imperceptible thin line, others are susceptible to the hypertrophy of a scar, and in the worst case, to the conversion into a keloid. A disturbed scarring process causes functional, aesthetic, and psychological disorders in the patient [1, 3]. Frequent symptoms associated with hypertrophic scars and keloids are: itching, pain, and restriction of movement, especially in the vicinity of the joints [4–7]. If left untreated, scars can cause contractures negatively affecting the patient’s health [8–10]. Hypertrophic scars and keloids are usually localised on the skin in the area of the chest, back, shoulders, in places of increased tension, and more often on flexor muscles [8].

Case report

A 56-year-old patient was admitted to the Holycross Cancer Centre in Kielce for the diagnosis of a tumour in the left breast. On the basis of material collected in a thick-needle biopsy performed on 1.02.2012 a triple-negative invasive duct carcinoma of the left breast at grade G2 (G2 ductal carcinoma invasivum mammae, “triple negative”) was found. Assessment of oestrogen receptors (ER) and progestogen (PgR) showed ER (1+), PgR (–), HER2 (–).
The patient was qualified for a modified radical mastectomy of the left breast in the Madden way (mastectomia sinistri modo Madden). The amputation of the left breast was performed from a transverse cutaneous cut. During the preparation of the armpit, numerous hard lymph nodes in all the levels of the armpit lymphatic system were found – one node at the top of the armpit, the others along the thoracic-dorsal bundle. The nodes were of different sizes and were hard. They all were removed. The postoperative material was sent for histopathological examination.
As a result of the pathological examination performed on 13.04.2012, a duct carcinoma G3 according to Elston-Ellis was found in the material taken during the surgery (the whole organ). The maximum size of the infiltrating cancer was 43 mm. There was no cancer cell embolism in the lumens of the thin-walled vessels around the tumour p T2. The receptors were determined in the previous study. Additional pathological data: Nottingham Prognostic Index – 4.8 points, lymph node status – 1 point, histological malignancy grade – 3 points, diameter of the infiltrating cancer in cm × 0.2–0.8 points. Twelve lymph nodes without metastases of cancer (0/12) were dissected from the left armpit.
Adjuvant chemotherapy was employed in the patient during the period 14.06.2012–11.10.2012. Six cycles of FEC (78 mg 5-fluorouracil, 110 mg epirubicin, 780 mg cyclophosphamide) were applied. As protection 8 mg Ondansetron and 4 mg Dexamethasoni natrii phosphas were applied.
The patient was admitted to the Department of Radiotherapy in order to have adjuvant radiotherapy during the period 7.01–2.02.2013. The area of irradiation included the chest walls on the left side and the over-and subclavian area in accordance with the treatment plan. A total dose of 45 Gy in 20 fractions was given.
The patient came to the Department of Rehabilitation on 26.04.2012. The range of motion in the shoulder joint was examined and the following results were found: flexion – 90°, abduction – 90°, and external rotation – 30°. The patient was recommended to learn self-massage of the left upper limb, exercises to relieve the left upper limb, self-adjunct exercise of the upper left limb, individual exercise of the left shoulder joint, massage and mobilisations of the postoperative scar, and a whirlpool massage of the upper left limb.
After the completion of radiotherapy, the patient reported pain in the vicinity of the postoperative scar and restriction of the abduction movement of the left upper limb in the shoulder joint. On physical examination the postoperative scar was plicate, drawn into an intercostal space, and segment immobile. The left armpit was without change. Swelling of the subcutaneous tissue was visible in an ultrasound examination done on 24.05.2013 in the plane of the postoperative scar (Figure 1).
The assessment of the postoperative scar was made on the basis of the Patient and Observer Scar Assessment Scale (POSAS) and Vancouver Scar Scale (VSS). Patient and Observer Scar Assessment Scales included two elements. One element was filled in by the observer, and the other was assessed by the patient. The patient assessed the thickness, flexibility, colour, pain, and itching. The observer assessed the vascularisation, pigmentation, thickness, and mobility. Each element was rated on a scale of 0 to 10, where 10 meant the worst conceivable scar. On the basis of Vancouver Scar Scale four variables were assessed: vascularisation, height (thickness), flexibility, and discoloration. The scoring range was 0 to 14, where 0 meant normal skin.
Pressotherapy of the postoperative scar with the use of non-sterile silicone dressings was employed for a period of 2 months (from 7.02.2013 to 9.02.2013) after obtaining the doctor’s consent. The patient was informed about the objectives, principles, and methods of pressotherapy of the scar, and the potential benefits and risks. A non-sterile silicone dressing was changed once a week. The patient was in the non-sterile silicone dressing all day and night with a 1-hour break for hygienic purposes.
Before starting the pressotherapy, the patient assessed the scar as painful, itchy, irregular, stiff, and of a colour different from the colour of normal skin. She assessed the pain of the scar as 10 on a 10-point scale (POSAS). Itching of the scar was assessed as 8/10. The colour, stiffness, and irregularity of the scar were assessed as being 10/10, and the thickness of the scar as 5/10. The second part of the scar assessment was conducted by the observer. The worst assessment (10/10) was obtained for the scar deformability, where 10 meant the worst imaginable scar. The bulge of the scars was rated at 8/10 and thickness at 3/10. The vascularisation was assessed as 3/10 and pigmentation as 2/10.
Then the scar was assessed on the basis of VSS. After the assessment of the vascularisation, pigmentation, deformability, and height, a score of 8 was obtained (on a scale of 0 to 14, where 0 meant normal skin) (Figure 2).
After 2 months of applying the pressotherapy in the vicinity of the scar, improvement in all the assessed parameters was obtained. Pain, itching, colour, stiffness, and thickness of the scar were assessed by the patient as 1 on a 10-point scale. The irregularity of the scar was assessed by the patient as 2/10. In the part assessed by the observer the greatest improvement was observed in the deformability and bulging of the scar at 2/10. The thickness was assessed as 2/10, and vascularisation and pigmentation as 1 on the 10-point scale. The result based on the assessment according to Vancouver Scar Scale was 4, whereas before the pressotherapy it was 8.

Discussion

Breast cancer is the most common malignant neoplasm in women. Breast cancer treatment is a combination therapy (surgery, radiotherapy, chemotherapy) and can be the cause of complications and functional disorders of the musculoskeletal, respiratory, circulatory, and nervous systems [11–13].
A common complication after mastectomy is extensive fibrillation of the operated area accompanied with the formation of contractures. Keloids can arise in the place of the postsurgical scar, which leads to the slowness or inhibition of the process of the lymphatic vessel regeneration. These changes may lead to the abnormal transport of lymph in the lymphatic system resulting in lymphoedema [12, 14, 15].
In patients after mastectomy, who were treated with radiotherapy, early and late complications of radiation are observed [16]. The most severe change is extensive scarring limiting the mobility of the chest and upper limb on the operated side [12, 17].
Treatment of hypertrophic scars and keloids is a serious problem for doctors. Often it is not possible to predict how the wound will heal and it is necessary to make efforts to prevent the development of hypertrophic scars and keloids. The choice of treatment depends on the individual needs of the patient, the clinical assessment of the scar, and the location and time of its creation [1]. Particular attention should be paid to high-risk patients. Patients who previously had problems with abnormal scar formation or who undergo procedures with a high risk of scarring, i.e. breast and chest surgery, are particularly exposed to the occurrence of a hypertrophic scar or keloid [18]. Even the smallest surgery leaves scars. Priorities and treatment goals should be determined in individual therapy (e.g. removing functional deformity, aesthetic improvement, prevention of recurrence after a surgical resection, or elimination of symptoms associated with the change) [1, 18]. Different methods are applied in the treatment of hypertrophic scars and keloids: surgical, physical, and pharmacological [1, 4, 19].
Silicone dressings in the form of plasters or gel are used in the treatment of hypertrophic scars and keloids [20, 21]. The use of silicone dressings is recommended as a safe, non-invasive, simple, and effective method of prophylaxis [18, 22–24]. The use of silicone dressings substantially improves the flexibility of old scars as compared to the scars untreated with plasters [1]. Most researchers believe that silicone dressings reduce the activity of the capillaries, reduce congestion, and reduce the production of fibroblasts and collagen, causing flattening of the scar. Randomised studies have shown that the use of silicone dressings is effective in improving the colour, size, and hardness of the scar [24]. Treatment of a patient who has a problem with a scar should be selected on the basis of the scar assessment. Assessment of the scar and the patient’s case history are the primary criteria for treatment.

Conclusions

In the presented case description, an improvement in all the studied parameters of the scar after mastectomy was achieved in a patient treated for breast cancer. The used pressotherapy of the postoperative scar proved to be effective and promising. Despite the achieved therapeutic success, the authors are unsatisfied with the applied, although recommended and widely used, methods for the assessment of the scar. This results from a large dose of subjectivity with which the used diagnostic methods were burdened. Although the POSAS is based on the binary nature of the scar assessment (patient and observer), in both cases the individual assessment elements of the measured parameters are burdened, in a natural way, with a lower or higher dose of subjectivity. A similar problem can occur during the application of the VSS. Bearing in mind the positive contact between the therapist and the patient formed during several weeks of therapy, and the connected willingness for effective help to the patient (by the therapist) and effective self-help (by the patient), the accuracy of the applied therapy with the use of subjective scales can be inaccurate. This does not change the fact that pressotherapy itself is a method effective in the treatment of hypertrophic scars and keloids. This is confirmed by extensive experience of specialists treating burns and numerous scientific reports demonstrating the efficacy of the method described and clinically applied by the authors. Clarification is needed in reference to the diagnostic methods, which, on the one hand, should be cheap and convenient to use, and on the other hand, should be sensitive and objective.
