Three-dimensional fluorescence laminar optical tomography (FLOT) can achieve resolutions of 100-200 µm and penetration depths of 2-3 mm. FLOT has been used in tissue engineering, neuroscience, as well as oncology. The limited dynamic range of the charge-coupled device-based system makes it difficult to image fluorescent samples with a large concentration difference, limits its penetration depth, and diminishes the quantitative accuracy of 3D reconstruction data. Here, incorporating the high-dynamic-range (HDR) method widely used in digital cameras, we present HDR-FLOT, increasing penetration depth and improving the ability to image fluorescent samples with a large concentration difference...

INTRODUCTION: Latissimus dorsi miniflap is a breast-conserving volume replacement technique for the reconstruction of large breast defects. While mammographic features of miniflap reconstruction have been described, little is known about the incidence, mode of presentation and size of local recurrence after this procedure. This study aimed to investigate the impact of latissimus dorsi miniflap reconstruction on the frequency, presentation and detection of local recurrence. METHODS: Clinical, radiological and pathological data were reviewed in 261 patients...

INTRODUCTION: The most important prognostic factor for oncological outcome of rectal cancer is radical surgical resection. In patients with locally advanced T4 rectal cancer (LARC) or locally recurrent rectal cancer (LRRC) (partial) resection of the urinary tract is frequently required to achieve radical resection. The psoas bladder hitch (PBH) technique is the first choice for reconstruction of the ureter after partial resection and this bladder-preserving technique should not influence the oncological outcome...

PROBLEM: During palatal fenestration procedure the vascularised, respiratory nasal lining is often sacrificed inadvertently. It normally functions to keep the inhaled air warm, humid and dust free. CONCLUSION: This vascularised nasal lining when uninvolved oncologically can easily be preserved. Preservation of the vascularised nasal lining shall decrease the leakage of nasal secretions and aid in the healing of reconstruction of the defect when local or regional flaps are used...

Microvascular reconstruction of ablative defects has become a mainstay of contemporary management of head and neck cancer patients. These techniques offer myriad tissue options that vary in character, volume, and components and have vastly improved the esthetic and functional outcomes achieved in this patient population. Although consensus exists regarding the reliability and functional and esthetic benefits of free tissue transfer, the same cannot be said for oncologic outcomes. The increase in resources required for the routine use of free tissue transfer has led to asking this question-Do vascularized free flaps allow for increased surgical margins and improvements in oncologic outcomes?...

BACKGROUND: There are several options for reconstruction of proximal humerus resections after wide resection for malignant tumors in children. The clavicula pro humero technique is a biologic option that has been used in the past, but there are only scant case reports and small series that comment on the results of the procedure. Because the longevity of children mandates a reconstruction with potential longevity not likely to be achieved by other techniques, the clavicula pro humero technique may be a potential option in selected patients...

Locally recurrent rectal cancer (LRRC) is a complex disease with far-reaching implications for the patient. Until recently, research was limited regarding surgical techniques that can increase the ability to perform an en bloc resection with negative margins. This has changed in recent years and therefore outcomes for these patients have improved. Novel radical techniques and adjuncts allow for more radical resections thereby improving the chance of negative resection margins and outcomes. In the past contraindications to surgery included anterior involvement of the pubic bone, sacral invasions above the level of S2/S3 and lateral pelvic wall involvement...

Eyelid reconstruction, though challenging, can produce a functional, esthetically pleasing lid. This should preferably be accomplished with a one-stage procedure, using robust, well-vascularized tissues similar to those being replaced, with minimal associated donor morbidity. According to the experience with Bichat pedicled flap in oral reconstruction, the authors propose the use of pedicle infraorbital fat pad for repair of conjunctival defect. Seven patients underwent eyelid reconstruction of full-thickness oncological or post-traumatic defects...

BACKGROUND: The preservation of the nipple areolar complex (NAC) for cancer treatment is still a matter of debate because of suspected increase of local recurrence and surgery-specific complications. The aim of the study was to investigate both the relapse risk associated with nipple sparing mastectomy (NSM) for breast cancer and women's satisfaction with preservation of the NAC. METHODS: We included retrospectively all patients who had skin-sparing mastectomy (SSM) or NSM from 2007 to 2012 for breast cancer or ductal carcinoma in situ (DCIS)...

OBJECTIVE: To determine whether the recently introduced Bayesian penalized likelihood PET reconstruction (Q.Clear) increases the visual conspicuity and SUVmax of small pulmonary nodules near the PET resolution limit, relative to ordered subset expectation maximization (OS-EM). METHODS: In this institutional review board-approved and HIPAA-compliant study, 29 FDG PET/CT scans performed on a five-ring GE Discovery IQ were retrospectively selected for pulmonary nodules described in the radiologist's report as "too small to characterize", or small lung nodules in patients at high risk for lung cancer...

BACKGROUND: The incidence of ipsilateral breast tumor recurrence (IBTR) seems to be higher in BRCA-positive than sporadic breast cancer. We compared the oncologic outcomes of BRCA-positive breast cancer patients managed with breast-conserving surgery, simple mastectomy or mastectomy followed by immediate reconstruction. MATERIALS/METHODS: Thirty four BRCA-positive breast cancers were grouped according to surgical treatment: breast-conserving surgery (n = 17), simple mastectomy (n = 9), and mastectomy followed by immediate reconstruction (n = 8)...

EDITORIAL
N J Bundred, J Thomas, J M J Dixon
The Kennedy report into the actions of the disgraced Breast Surgeon, Paterson focussed on issues of informed consent for mastectomy, management of surgical margins and raised concerns about local recurrence rates and the increasing emphasis on cosmesis after mastectomy for breast cancer. This article assesses whether Kennedy's recommendations apply to the UK as a whole and how to address these issues. New GMC advice on consent and newer nonevidenced innovations in immediate reconstruction have altered the level of informed consent required...

BACKGROUND: The reconstruction of meta-/diaphyseal bone defects following bone tumour resection is challenging, and biological treatment options should be applied whenever possible, especially in benign lesions and early stage sarcomas. We aimed to evaluate the results of segmental (SR) and hemicortical reconstructions (HR) at the extremities using non-vascularised fibula grafts. METHODS: We retrospectively enrolled 36 patients who were treated with non-vascularised fibula reconstructions (15 SR, 21 HR) after bone tumour resection (15 malignant, 21 benign)...

BACKGROUND: Following resection of malignant tumors of the spine and pelvis, reconstructive surgeons often face large structural defects. Unlike reconstruction in the extremities, wherein a free vascularized fibular graft (FVFG) is a highly utilized option for segmental osseous reconstruction, there are limited data on the use of an FVFG in the spine and pelvis. The aim of this study was to review our institution's experience with reconstruction with use of an FVFG following oncological resection in the spine and pelvis...

Head and neck cancer surgery is often a complex multi-step procedure that includes major resections, vascularised tissue reconstruction, and extensive neck dissection. The upper aerodigestive tract mucosal lining is often disrupted during surgery, which requires the management of a clean-contaminated field and the need to reconstruct the mucosal lining. With bacterial contamination, surgical site infections (SSI) are a serious complication that can result in delayed wound healing, wound breakdown, fistula formation, and compromised tissue reconstruction...

Skin-sparing (SSM) and nipple-sparing (NSM) mastectomies are relatively new conservative surgical approaches to breast cancer. In SSM most of the breast skin is conserved to create a pocket that facilitates immediate breast reconstruction with implant or autologous graft to achieve a quality cosmetic outcome. NSM is closely similar except that the nipple-areola complex (NAC) is also conserved. Meta-analyses indicate that outcomes for SSM and NSM do not differ from those for non-conservative mastectomies. Recurrence rates in the NAC after NSM are acceptably low (0-3...

Unplanned hospital readmission following head and neck cancer surgery is common and associated with significant negative consequences. Because of the vital role that microvascular free tissue transfer plays in the management of head and neck oncologic defects, its relationship to unplanned hospital readmission requires attention. In this review, the incidence of, risk factors for, and reasons for unplanned readmission in patients undergoing free flap reconstruction for head and neck cancer are analyzed. The role of free flap reconstruction as a separate risk factor for unplanned readmission in patients with head and neck cancer is described...
