A systematic review of the safety and efficacy of currently used treatment modalities in the treatment of patients with PIK3CA-related overgrowth spectrum. J Vasc Surg Venous Lymphat Disord 2021; 10:527-538.e2. [PMID: 34358672 DOI: 10.1016/j.jvsv.2021.07.008] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/03/2021] [Accepted: 07/22/2021] [Indexed: 12/29/2022]
Abstract
BACKGROUND PIK3CA (activating mutations of the p110α subunit of phosphatidylinositol 3-kinases)-related overgrowth spectrums (PROS) include a variety of clinical presentations that are associated with hypertrophy of different parts of the body. We performed a systematic literature review to assess the current treatment options and their efficacy and safety for PROS. METHODS A literature search was performed in Embase, MEDLINE (Ovid), Web of Science Core Collection, Cochrane Central Register of Controlled Trials, ClinicalTrials.gov, and Google Scholar to retrieve studies on the treatment of hypertrophy in PROS. Randomized controlled trials, cohort studies, and case series with ≥10 patients were included in the present review. The titles, abstracts, and full text were assessed by two reviewers independently. The risk of bias was assessed using the Newcastle-Ottawa scale. RESULTS We included 16 studies of the treatment of hypertrophy in PROS patients, 13 (81.3%) from clinical retrospective studies and 3 (13.7%) from prospective cohort studies. The risk of bias grade was low for 2, medium for 12, and high for 2 studies. Of the 16 studies, 13 reported on surgical treatment and 3 reported pharmacologic treatment using phosphatidylinositol-3-kinase (PI3K)/mammalian target of rapamycin (mTOR) pathway inhibitors in PROS patients. In 3 studies, PROS was defined by a mutation in the PIK3CA gene, and 13 studies relied on a clinical definition of PROS. Surgical therapy was beneficial for a specific subgroup of PROS (macrodactyly). However, little has been reported concerning surgery and the potential benefits for other PROS entities. The reported side effects after surgical therapy were mostly prolonged wound healing or scarring. PI3K/mTOR pathway inhibition was beneficial in patients with PROS by reducing hypertrophy and systemic symptoms. The adverse effects reported included infection, changes in blood count, liver enzymes, and metabolic measures. CONCLUSIONS Surgery is a locally limited treatment option for specific types of PROS. A promising treatment option for PROS is pharmacologic PIK3CA inhibition. However, the level of evidence on the treatment of overgrowth in PROS patients is limited.

[PMID: 33384233 DOI: 10.1016/j.bjps.2020.11.032] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/01/2020] [Revised: 09/18/2020] [Accepted: 11/22/2020] [Indexed: 10/22/2022]
Abstract
The role of the plantar nerve in the pathogenesis of macrodactyly of the foot is unknown. We investigated the distribution of affected toes and forefoot in 27 feet of 26 patients with pedal macrodactyly, and how this relates to innervation of the affected plantar nerve. A preoperative ultrasound examination was performed to determine the diameter and structure of the plantar nerve. Histologic findings were recorded during surgery. The microstructure of affected plantar nerves was evaluated by hematoxylin-eosin staining, while S100 expression was assessed by immunofluorescence analysis. Phosphatidylinositol-4,5-bisphosphate 3-kinase catalytic subunit alpha (PIK3CA) gene mutation in the affected nerve tissue was detected by Sanger DNA sequencing. The affected toes and forefoot involved innervation of the medial plantar nerve in 25/27 feet, the lateral plantar nerve in one foot, and both medial and lateral plantar nerves in one foot. All affected plantar nerves, which were accompanied by a fatty strip, were surrounded by or infiltrated with fat. The affected plantar nerves showed enlargement, a tortuous course, fatty infiltration, or a combination of these. Pathologic changes in affected plantar nerves involved only the epineurium and not the perineurium or endoneurium. Expression of the Schwann cell marker S100 was absent in some areas of affected nerves. Sequencing of PIK3CA exons identified a gain-of-function mutation (p.His1047Arg) in affected plantar nerves. These results indicate that pathologic impairment of the plantar nerve can lead to macrodactyly of the foot, which may be considered as a nerve trunk disease.

Abstract
Macrodactyly of the foot is a rare but disabling condition. We present the results of surgery on 18 feet of 16 patients, who underwent ray amputation and were followed-up for more than two years at a mean of 80 months (25 to 198). We radiologically measured the intermetatarsal width and forefoot area pre-operatively and at six weeks and two years after surgery. We also evaluated the clinical results using the Oxford Ankle Foot Questionnaire for children (OxAFQ-C) and the Questionnaire for Foot Macrodactyly. The intermetatarsal width and forefoot area ratios were significantly decreased after surgery. The mean OxAFQ-C score was 42 (16 to 57) pre-operatively, improving to 47 (5 to 60) at two years post-operatively (p = 0.021). The mean questionnaire for Foot Macrodactyly score two years after surgery was 8 (6 to 10). Ray amputation gave a measurable reduction in foot size with excellent functional results. For patients with metatarsal involvement, a motionless toe, or involvement of multiple digits, ray amputation is a clinically effective option which is acceptable to patients.

Abstract
UNLABELLED Macrodystrophia lipomatosa (MDL) is a rare, nonhereditary, congenital malformation that primarily affects the proliferation of mesenchymal structures. It presents with localized macrodactyly of one or more digits. The characteristic pathology is associated with hypertrophic fibroadipose tissues, more so to the plantar aspect of the foot. This condition can pose a threat to vascular supply, innervation, and even joint function. We present a single case of a 4-year-old male patient who presented with progressive enlargement of a unilateral left fifth digit since birth. The patient became increasingly symptomatic. Amputation was the selected treatment, and on pathological review of the specimen, the diagnosis of MDL was confirmed. The patient is approximately 1 year postoperative and has recovered uneventfully with an improved quality of life. The purpose of this article is to raise awareness of this condition with an emphasis on diagnosis through ancillary imaging results. LEVELS OF EVIDENCE Therapeutic, Level IV: Case report.

Abstract
Syndromes with focal overgrowth are sporadic diseases and comprise Proteus syndrome and congenital lipomatous overgrowth, vascular malformations, and epidermal naevi (CLOVE) syndrome, and isolated hemihyperplasia. We describe 3 children classified according to standard criteria with dysregulated growth of various tissues that was excised, together with excess toes, and tumours. Correct classification facilitates diagnosis and operations. Interdisciplinary treatment and follow-up are recommended to prevent disfiguration.

Abstract
Macrodactyly involving the great toe is difficult to treat when both the functional and cosmetic problems are addressed simultaneously. Partial resection of the distal phalanx is an easy way to reduce the length of the involved toe. However, there are cosmetic concerns with loss of the toenail. The authors report on a clinical case in which shortening and debulking of the toe was performed while preserving the hallux nail. The nail complex was transferred as an island flap to the dorsal aspect of the proximal phalanx. At the 1-year follow-up, the length of the reconstructed toe was significantly decreased, with a normal-looking nail.

Abstract
The tumor described here as lipofibromatosis is a rare pediatric neoplasm that has been variously interpreted as a type of infantile or juvenile fibromatosis, a variant of fibrous hamartoma of infancy, and a fibrosing lipoblastoma. This report details the clinicopathologic features associated with 45 cases of this soft tissue entity. The study group consisted of 32 males, 12 females, and one person of unstated gender. The patients presented with a soft tissue mass (range, 1-7 cm) involving the hand (n = 18), arm (n = 8), leg (n = 7), foot (n = 6), trunk (n = 5), or head (n = 1). Eight tumors were evident at birth. The individuals ranged in age from 11 days to 12 years (median age, 1 yr) at the time of initial biopsy or resection. Microscopic examination revealed abundant adipose tissue with a spindled fibroblastic element that chiefly involved the septa of fat and skeletal muscle. The process generally did not cause extensive architectural effacement of fat as is common with conventional fibromatoses, and it did not have a primitive nodular fibromyxoid component as is characteristic of fibrous hamartoma of infancy. The fibroblastic element exhibited focal fascicular growth and typically had limited mitotic activity (< or = 1 mitosis/ 10 high-power fields) and cytologic atypia. Oftentimes, small collections of univacuolated cells were present at the interface between some of the fibroblastic fascicles and the mature adipocytes. The tumors entrapped vessels (n = 45), nerves (n = 44), skin adnexa (n = 16), and skeletal muscle (n = 18). Focal immunoreactivity was present in some tumors for CD99, CD34, alpha-smooth muscle actin, BCL-2, and less frequently, S-100 protein, muscle actin (HUC 1-1), and EMA. However, no reactivity was detected for desmin (D33 and D-ER- 1 clones), keratins, or CD57. Follow-up data were available for 25 individuals (median follow-up period, 6 yrs 7 mos) with regrowth of the tumor or persistent disease documented in 17 (72%). The following events were more common in the group with recurrent or persistent disease: congenital onset, male sex, hand and foot location, incomplete excision, and mitotic activity in the fibroblastic element. Although it is likely this tumor comprises part of the spectrum of what has been referred to in the literature as infantile/juvenile fibromatosis, its clinicopathologic features and, in particular, its distinctive tendency to contain fat as an integral component, warrant separate classification as a "lipofibromatosis."

Abstract
Macrodactyly can affect the fingers and/or toes1. Histopathologic examination will distinguish macrodactylia fibrolipomatosis or neural fibrolipoma with macrodactyly, from macrodactylia as a part of neurofibromatosis. Surgical repair is aimed at decreasing the size of the affected foot so it is as near in size and shape to the normal foot as possible. Surgical approaches have included reconstructive surgery (usually staged debulking procedures), epiphyseal plate arrest and amputation. Repeated reconstructive surgical procedures, as illustrated in this report covering patient care over a 15 year period, are usually necessary due to recurring soft tissue and boney enlargement.

Abstract
The recommended treatment for macrodactyly of the foot will often include epiphysiodesis of the proximal phalanx in an attempt to halt further longitudinal growth of the toe. Nine patients who underwent open epiphysiodesis and debulking of the excess soft tissues involving 11 toes were reviewed to evaluate the effectiveness of this procedure. In 9 of 11 toes, overall length of the proximal phalanx did not change after surgery. Two toes demonstrated continued growth; one of these toes underwent a repeat epiphysiodesis of the phalanx, and the other foot underwent epiphysiodesis of the affected metatarsal. Overall, this surgical approach led to radiographic results that satisfied the surgical goals.
