Quality of Life in Palliative Post-mastectomy Reconstruction: Keystone versus Rotational Flap.

Late stage breast cancer presents with malignant wound causing skin infiltration, pain, bleeding, and malodour, which affect quality of life (QoL). Palliative mastectomy aims to eliminate wound symptoms and requires prolonged wound care to improve QoL. This study aimed to prospectively investigate QoL differences in 2 alternative reconstructive methods: keystone flap and rotational flap. METHODS: Twenty-four late stage breast cancer patients with symptoms of cancer wounds were included in this study. They were divided into 2 groups: keystone flap and rotational flap. Each patient's QoL was evaluated using EORTC QLQ-C30 and QLQ-BR23 before and 3 weeks after surgery. RESULTS: Global health post-surgery was significantly improved compared with pre-surgery in all patients (P < 0.001), across both the keystone (P = 0.018) and rotational groups (P = 0.007). Breast symptoms post-surgery were also improved compared with pre-surgery in all patients (P = 0.035). However, when analyzed per group, breast symptoms were only improved significantly in the keystone group (P = 0.013) but not in the rotational group (P = 0.575). When compared between 2 groups, future perspective post-surgery in the keystone group [100 (0-100)] was better than the rotational group [66.7 (0-100)], (P = 0.020). CONCLUSIONS: Reconstructive surgery after mastectomy improves QoL in late stage breast cancer patients. The keystone flap is superior to the rotational flap in improving global health and breast symptoms.

A systematic review of the keystone design perforator island flap in the reconstruction of trunk defects.

The keystone design perforator island flap can be utilized in the repair of trunk defects. A systematic review was carried out to identify the complication rates of the use of this flap to treat such defects. The MEDLINE, Embase, Cochrane Library, and PubMed Central databases were searched for articles published between January 2003 and December 2018 that reported the use of keystone design perforator island flaps in the repair of trunk defects. Study selection was conducted in alignment with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement. Eight articles involving a total of 54 flaps satisfied the inclusion criteria. The most frequently reported cause of trunk defects was oncologic resection (64.4%). The overall complication rate was 35.2%, and complications included infection (11.1%), wound dehiscence (7.4%), delayed healing (7.4%), and partial flap loss (1.9%). The keystone design perforator island flap is associated with a high success rate and low technical complexity. Despite minor complications, keystone design flaps could be a preferred choice for trunk reconstruction.

Keystone Perforator Island Flap for Postmastectomy Defect Resurfacing in Late-stage Breast Cancer Patients.

Late-stage breast cancer usually presents with locally advanced disease, with or without metastasis. The primary tumor is typically large with skin infiltration which affects quality of life. Surgical resection will result in an extensive defect which potentially deteriorates patients' quality of life if not properly managed. Keystone perforator island flap (KPIF) is a local advancement flap based on multiple perforators which can be a reliable reconstructive method to close an extensive defect. METHODS: This is a case series of 11 patients with symptomatic late-stage breast cancers indicated for neoadjuvant chemotherapy and subsequent mastectomy at Dharmais Cancer Hospital. The postmastectomy defect was closed with KPIF and clinical evaluation included flap success rate, percentage of flap necrotic area, and quality of life. There are modifications of the KPIF consisting of the more rounded shape and additional flap movement of the flap's distal lateral ends to the center resembling an "omega" conformation. RESULTS: Mean percentage of flap necrosis area was 9.7% and none of the patients needed additional surgery. The patients' quality of life evaluated using Patient-reported Aesthetic European Organization for Research and Treatment of Cancer (EORTC) Quality of Life, Questionnaire-Core 30-questions (QLQ-C30) and Quality of Life, Questionnaire-Breast Cancer-23-questions (QLQ-BR23) was fair, with sufficiently good scores for global health status and functional scale, and minimal symptomatology burden. The lowest score was for fatigue and financial difficulties parameters from QLQ-C30 and sexual functioning and future perspective from QLQ-BR23. CONCLUSION: This is a preliminary study to show that a KPIF could be considered as a method for defect-resurfacing reconstruction after mastectomy.
