Skin-reducing mastectomy and direct-to-implant reconstruction in giant phyllodes tumour of breast: case report

Breast cancer in pregnancy: concurrent cesarean section, nipple-sparing mastectomy, and immediate breast reconstruction-case report

Background

Pregnancy-associated breast cancer (PABC), with an incidence rate from 1:3,000 to 1:10,000 deliveries, is the most frequent cancer during pregnancy. PABC appropriate management must take into consideration both the maternal oncological safety and the fetal health, thus posing a challenge for the mother, the baby, and the clinicians. The treatment should adhere as closely as possible to the breast cancer (BC) guidelines. Therefore, surgery is a mainstay, and, when mastectomy is required, breast reconstruction (BR) is a topic of debate. To minimize the risks to the baby, most surgeons postpone BR to delivery. However, a delayed breast reconstruction (DBR) could affect the outcome. In the present case, we report cesarean section concurrent with mastectomy and immediate breast reconstruction (IBR).

Methods

A 37-year-old patient, at the 36th week of pregnancy with PABC, underwent simultaneous cesarean delivery, nipple-sparing mastectomy, and IBR. To minimize risks for the newborn, cesarean was firstly performed under spinal anesthesia. Immediately after, breast surgery, including mastectomy and IBR, was performed under general anesthesia. Partial submuscular IBR with an acellular porcine dermal matrix concluded the surgical procedure. Lactation was inhibited, and adjuvant chemotherapy and hormone therapy were administered to the patient.

Results

In a single surgical session, cesarean delivery, subcutaneous mastectomy, axillary dissection, and IBR were successfully carried out. No early or late postoperative complications were reported for both the patient and the newborn. Histopathological investigation reported a multifocal and multicentric infiltrating ductal carcinoma. After a 6-year follow-up, the patient is alive and well.

Conclusion

To the best of our knowledge, this is the first reported case of concomitant cesarean delivery, PABC mastectomy, axillary dissection, and IBR. This surgical strategy allowed PABC treatment by the BC guideline, minimizing the newborn's disadvantage and permitting, at the same time, the best final BR outcome.

Skin reducing nipple sparing mastectomy with immediate breast reconstruction for huge borderline phyllodes tumor of the breast: Case report

INTRODUCTION

Borderline phyllodes tumors are very infrequent breast tumors encountered by surgeons.

CASE PRESENTATION

We present a case of a young woman with a very large borderline phyllodes tumor measuring 20 cm × 20 cm, involving almost all of the breast, causing gross asymmetry of the breasts.

DISCUSSION

The patient wished to maintain symmetry following the surgery as a result of which a simple mastectomy followed by implant based Immediate breast reconstruction was planned. The patient had an uneventful recovery postoperatively with equal breast size bilaterally.

CONCLUSION

Implant based immediate breast reconstruction thus provides a comprehensive solution and excellent cosmesis for women with very large borderline phyllodes requiring mastectomy.

Recurrent borderline phyllodes tumor of the breast submitted to mastectomy and immediate reconstruction: Case report

•

Phyllodes tumors of the breast are rare fibroepithelial neoplasms.

•

They are histologically classified into benign, borderline and malignant variants.

•

Anatomopathological examination is considered the definitive diagnostic method.

•

They have a high rate of local recurrence and the possibility of metastases.

•

Surgery is the definitive treatment and adjuvant therapy is controversial.

Introduction

Phyllodes tumors are biphasic fibroepithelial tumors that account for fewer than 1% of mammary tumors. They usually appear in middle-aged women, with an average size of 4–7 cm and rapid growth.

Presentation of case

A 25-year-old woman sought care after excision of recurrent nodules in the right breast, with a diagnosis of borderline phyllodes tumor. She had no new lesions on physical examination. Imaging studies revealed an anechoic collection and nodular areas in a previous surgical site, correlated with pathology. Immuno-histochemical examination was positive for vimentin, calponin, Ki-67 and estrogen receptor. Systemic staging did not show metastases. Skin-reducing mastectomy was performed on the right side, followed by reconstruction and left reduction mammaplasty for symmetry. At 8-month follow-up, there was no relapse of the lesions on clinical and ultrasonographic examinations.

Discussion

Phyllodes tumors are rare neoplasms characterized by rapid growth, occurring in women between 35–55 years of age. They are classified as benign, borderline and malignant, according to histological parameters. There are reports of genetic mutations in TP53 associated with malignant phyllodes tumor. On immunohistochemistry, there is a greater tendency to malignancy in tumors with Ki-67 and estrogen receptor expression. Imaging methods may aid in diagnosis, which is only definitive after excision and histopathological analysis of the tumor. These tumors have high local recurrence rates and possibility of metastases, closely related to histology.

Conclusion

Phyllodes tumors are a great challenge to the surgeon. Treatment is surgical, with wide excision; radiotherapy and chemotherapy are controversial.

Breast reconstruction with a dermal sling: a systematic review of surgical modifications

A dermal sling (DS) is used to cover the implant with two layers of tissue when immediate breast reconstruction is performed in women with large and ptotic breasts. It works as an autologous acellular dermal matrix/mesh that can be used to control the implant pocket and inframammary fold, without inferring an extra foreign material and higher costs. There is relatively little published about the DS technique. The primary aim of this study was to systematically review published surgical modifications to the dermal sling (DS). The secondary aim was to investigate what implants have been used. Relevant databases were searched for articles and abstracts published between January 1990 and September 2018. Inclusion criteria were studied and case reports on DS meeting the criteria defined in a PICO. Review articles were excluded. Total evidence for the different types of DSs was graded according to GRADE. A total of 428 abstracts were retrieved. Of these 373 abstracts did not meet the inclusion criteria and were excluded, leaving 54 abstracts. Nine categories of surgical modifications could be identified: classic dermal sling (DS) with minor modifications, non Wise-pattern mastectomy DS, nipple areola complex bearing DS, DS in combination with a matrix/mesh, DS as a suture line protection technique, DS with a modified circulatory basis, DS without an implant, DS as an immediate-delayed technique and pre-pectoral DS. The evidence for DS as a surgical technique is very low (GRADE ⊕). The DS can be used with both permanent implants and tissue expanders (GRADE ⊕).

Surgical excision and oncoplastic breast surgery in 32 patients with benign phyllodes tumors

Background

The purpose of this study was to assess the effectiveness and safety in patients with benign phyllodes after performing local excision and following with intra-operative breast flap reconstruction.

Methods

Patients (n = 32) with eligible breast cystosarcoma phyllodes underwent wide local excision followed by intra-operative breast flap reconstruction. Primary outcome measures included average operative time, length of in-hospital stay, postoperative recurrence, and intra-operative and postoperative complications.

Results

Thirty-two patients who underwent surgical excision and oncoplastic breast surgery were evaluated using the BCCT.core software. A satisfactory symmetrical breast shape was achieved. The average operative time was 56.3 ± 8.2 min. The average postoperative duration of hospitalization was 3.7 ± 1.2 days. While there was no breast disease recurred during the 1 to 8-year follow-up period.

Conclusions

Wide local excision accompanied by intra-operative breast flap reconstruction could be adopted for removing benign phyllodes tumors while retaining the basic shape of the breast.
