[Therapeutic alternatives to surgical treatment of malignant eyelid tumors and their precursors]. / Therapiealternativen zur chirurgischen Versorgung maligner Lidtumoren und deren Vorläuferstufen.

The treatment of choice for malignant eyelid tumors is surgical excision. If this is not feasible or undesirable, a number of alternative treatments are available. Possible systemic preparations are vismodegib and sonidegib for basal cell carcinoma as well as cetuximab and cemiplimab for squamous cell carcinoma. Cryodestruction is possible for superficial tumors. In situ findings can be treated with the local preparations imiquimod or 5­fluorouracil and with photodynamic therapy. An interdisciplinary cooperation with dermatologists is advisable.

Orbital/Periorbital Plexiform Neurofibromas in Children with Neurofibromatosis Type 1: Multidisciplinary Recommendations for Care.

TOPIC: Children and adults with neurofibromatosis type 1 (NF1), a common autosomal dominant condition, manifest a variety of ophthalmologic conditions. Plexiform neurofibromas (PNs) involving the eyelid, orbit, periorbital, and facial structures (orbital-periorbital plexiform neurofibroma [OPPN]) can result in significant visual loss in children. Equally important, OPPNs can cause significant alteration in physical appearance secondary to proptosis, ptosis, and facial disfigurement, leading to social embarrassment and decreased self-esteem. CLINICAL RELEVANCE: Although NF1 is a relatively common disease in which routine ophthalmologic examinations are required, no formal recommendations for clinical care of children with OPPNs exist. Although medical and surgical interventions have been reported, there are no agreed-on criteria for when OPPNs require therapy and which treatment produces the best outcome. METHODS: Because a multidisciplinary team of specialists (oculofacial plastics, pediatric ophthalmology, neuro-ophthalmology, medical genetics, and neuro-oncology) direct management decisions, the absence of a uniform outcome measure that represents visual or aesthetic sequelae complicates the design of evidence-based studies and feasible clinical trials. RESULTS: In September 2013, a multidisciplinary task force, composed of pediatric practitioners from tertiary care centers experienced in caring for children with OPPN, was convened to address the lack of clinical care guidelines for children with OPPN. CONCLUSIONS: This consensus statement provides recommendations for ophthalmologic monitoring, outlines treatment indications and forthcoming biologic therapy, and discusses challenges to performing clinical trials in this complicated condition.

Laser treatment of periocular skin conditions.

Advances in laser technology in recent decades have increased the options for the treatment of dermatologic conditions of the eye and eyelid. Benign tumors can be laser-ablated with relative ease, and vascular and melanocytic lesions can be precisely targeted with modern lasers. In this contribution, we review treatment of periocular pigmented lesions, including melanocytic nevi and nevus of Ota; vascular lesions including telangiectasias, port wine stains, and infantile hemangiomas; hair removal; eyeliner tattoo removal; laser ablation of common benign periocular tumors, such as syringomas, xanthelasma, milia, and seborrheic keratoses; and laser resurfacing. The recent advent of fractionated laser technology has resulted in dramatically decreased healing times for periocular skin resurfacing and fewer adverse effects. Fractionated laser resurfacing has now nearly supplanted traditional full-field laser resurfacing, and safe treatment of rhytides on the thin skin of the eyelids is possible. Proper eye protection is, of course, essential when using lasers near the eye. Patient preparation, safety precautions, and risks--intraocular and extraocular--are discussed herein. As laser technology continues to advance, we are sure to see improvements in current treatments, as well as development of new applications of cutaneous lasers.

Squamous Cell Carcinoma of the Caruncle.

Squamous cell carcinoma (SCC) of the lacrimal caruncle is a rare entity. The authors report the management and outcomes of 3 cases of caruncle SCC. Case 1 underwent wide margin surgical excision with adjuvant topical chemotherapy for a poorly differentiated SCC. He later developed regional lymph node metastasis and required modified radical neck dissection. Case 2 underwent wide margin surgical excision with cryotherapy and adjuvant topical chemotherapy for an invasive moderately differentiated SCC. She later developed a recurrence and underwent orbital exenteration. Case 3 was a moderately differentiated SCC treated with wide margin excision alone and had no recurrence during 5-year follow up. Careful surveillance of caruncle SCC is required, given the observed propensity for local recurrence and/or regional metastasis.

[Management of eyelid tumors: general considerations]. / Prise en charge des tumeurs palpébrales : considérations générales.

Despite the fact that the majority of eyelid tumors are benign, proper management in daily practice requires detection of the malignant ones. Several clinical criteria are usually proposed to support or reject a hypothesis of malignancy; however, most are of limited reliability. In any case of doubt, outpatient biopsy is recommended, so as to establish the correct diagnosis and formulate the most appropriate treatment plan. In all facial malignancies, the first (and absolutely mandatory) consideration is control of the cancer. Then, restoration of eyelid function can be addressed, in the following order: protection of the globe by complete dynamic eyelid closure and opening, visual function (and prevention of possible deprivation amblyopia) by insuring a clear visual axis, correction of the tear film, efficient lachrymal drainage, and only then the role of the eyelids in facial expression and esthetics. For most malignant eyelid tumors, the best assurance of complete excision is obtained by extemporaneous examination of the resection margins by frozen section (by Mohs' micrographic surgery techniques, or a variation thereof). Currently, advancement and transposition flaps, possibly in combination with tarso-conjunctival or skin grafts, are the most utilised techniques. Despite the lack of histological verification, new treatment modalities, including topical chemotherapy, photodynamic therapy and cryotherapy, may provide interesting treatment options, particularly in collaboration with the dermatologist.

Re-irradiation and hyperthermia for recurrent breast cancer in the orbital region: a case report.

Based on the good results of re-irradiation plus hyperthermia in breast cancer recurrences on the chest wall, it was decided to offer similar treatment to a patient with recurrent metastatic breast cancer in the orbital region. A female patient was diagnosed in 1997 with breast cancer stage T4N0M0. She was treated with six neo-adjuvant chemotherapy courses and mastectomy, followed by hormonal treatment. In December 1998, she was diagnosed with metastatic disease in the medial upper quadrant of the left orbit. This was excised, followed by 40 Gy radiotherapy. Nine months later, the tumour had recurred in the left orbit at the margin of the radiotherapy field. This again was treated with surgery, followed by 30 Gy radiotherapy. Two months thereafter, the eyelid tumour progressed and hormonal therapy was changed, without an effect on the eyelid tumour. Screening gave no evidence of tumour activity elsewhere. The patient preferred treatment with re-irradiation plus hyperthermia to a surgical approach. Eight fractions of 4 Gy were given in 4 weeks, combined with once weekly hyperthermia. One week after treatment, the tumour had regressed completely. The patient died 22 months following treatment. Until last follow-up, a few weeks before death, the patient mentioned a dry left eye for which she used eyedrops, an unchanged vision and no further difficulties. On examination, there was epilation of the eyelids, a slight conjunctival oedema, no subcutaneous fibrosis and no evidence of tumour regrowth. For this patient, a surgical approach would have resulted in loss of the left eye. Toxicity of re-irradiation plus hyperthermia might lead to either a loss of vision or a delayed loss of her left eye due to treatment-induced toxicity. The chosen local treatment resulted in a very good palliative effect, which lasted for the patient's remaining lifetime of 22 months.

[Local microwave hyperthermia in the combined treatment of malignant tumors of the eyelids and orbit]. / Lokal'naia sverkhvysokochastotnaia gipertermiia v kompleksnom lechenii zlokachestvennykh opukholei vek i orbity.

The paper is concerned with the results of experimental investigation of the effect of different microwave radiation ranges on some segments of the rabbit's eye and its clinical application to the treatment of malignant tumors of the lid and orbit. It has been shown that the effect of definite microwave radiation ranges on the rabbit's eye, while ensuring necessary conditions for local hyperthermia (43-45 degrees C), does not cause clinically visible changes in the refractive media and fundus of the eye during 3 months after irradiation. The results of effective combined therapy of advanced malignant tumors of the lid and orbit in 5 patients are presented. Our experience in using definite ranges of local microwave radiation for therapy of malignant eye tumors has shown the feasibility, prospects and relative safety of the method in cancer ophthalmology.
