Comparative Study of the Use of Beta Blocker and Oral Corticosteroid in the Treatment of Infantile Hemangioma
A Comparative Study of the Use of Beta Blocker and Oral Corticosteroid in the Treatment of Proliferative and Involuting Cutaneous Infantile Hemangioma

Infantile Hemangioma (IH) is infancy's most common vascular tumor of infancy and most frequent benign neoplasm.

Treatment of IHs is indicated for approximately 10 to 20% of the cases. Two groups can be defined amongst indications for treatment: patients with absolute indication for treatment and patients with relative indication for treatment.

Absolute or emergency indications comprise function or life threatening situations such as obstruction of airways, obstruction of vision, congestive heart failure, hepatic and coagulation problems.

The following are considered relative indications: cases of large and disfiguring facial hemangiomas; locations that can result in a deformity and/ or permanent scar (nose, ear, lip, glabellar area); extensive face hemangiomas, mainly when there is dermal damage (more probable to scar); local complications such as ulceration, infection and bleeding as well as small hemangiomas in exposed areas (hands and face), mainly if pedunculated due to its ease of excision2,7.

Treatment modalities vary according to the extension, location, presence of complications and the evolutional phase. A combination of various treatments is possible.

Beta blockers are being used in children for approximately 40 years, with proven clinical safety and no cases of death or cardiovascular disease resulting from its direct use. Recently it was reported the use of beta blockers (propanolol) for IH treatment, with significant reduction of tumor volume after introduction of the beta blocker, in a short period of time, with stable results after the end of treatment, which suggested evidences of the benefits of this drug in the tumor treatment The proposal of this study is to assess the use of propanolol in IH treatment, quantifying its effectiveness and safety under continuous monitoring and comparing it to the use of oral corticosteroid. The investigators propose the assessment of the betablockers' use in comparison to the use of corticosteroids in infants with IH in the proliferative or involuting phases, with indication for clinical treatment, and that are not alarming nor urgent; in other words, the current relative indications for treatment.

  1. Introduction Infantile Hemangioma (IH) is infancy's most common vascular tumor of infancy and most frequent benign neoplasm. In 1996 the "International Society for the Study of Vascular Anomalies" has defined the guidelines for the diagnosis and treatment of vascular anomalies. Hemangioma is one of the many vascular tumors that were classified. Clinically, it presents well defined characteristics and a natural history divided into three phases. The proliferative phase represents an initial growth phase through hyperplasia and hypertrophy, followed by a spontaneous regression phase called the involuting phase. The involuted phase represents a final phase with no more biological activity; however, it doesn't necessarily corresponds to the complete tumor disappearance once there is a replacement by fibro-fatty tissue. IH affects one in every 10 to 20 Caucasian infants.There is a predilection for females at a 3:1 to 5:1 proportion, a higher incidence in premature infants, in newborns with low birth weight, in those whose pregnancy presented placentary anomalies and in neonates from mothers with multiple pregnancies. Fifty to sixty percent of IH affect the head and neck area.

    In the proliferative phase the tumor may reach considerable dimensions and depending on its location and proximity to vital structures, it may result in the obstruction or invasion of organs. This would cause a functional problem and even impose a threat to infant's life. There is a variable incidence of local complications such as necrosis, repetitive ulcerations, bleeding and infections, apart from systemic complications such as coagulopathy and high output cardiac failure.

    After involution, IHs may leave scars or contour deformities resulting in deformities and eventual psychological damage. Treatment of IHs is indicated for approximately 10 to 20% of the cases. Two groups can be defined amongst indications for treatment: patients with absolute indication and patients with relative indication for treatment. Absolute or emergency indications comprise function or life threatening situations such as obstruction of airways, obstruction of vision, congestive heart failure, hepatic and coagulation problems.

    The following are considered relative indications: cases of large and disfiguring facial hemangiomas; locations that can result in a deformity and/ or permanent scar (nose, ear, lip, glabellar area); extensive face hemangiomas, mainly when there is dermal damage (more probable to scar); local complications such as ulceration, infection and bleeding as well as small hemangiomas in exposed areas (hands and face), mainly if pedunculated due to its ease of excision.

    Treatment modalities vary according to the extension, location, presence of complications and the evolutional phase. A combination of various treatments is possible.

    In cases of relative indication, surgical treatment is mostly indicated for lesions in growing areas with disfiguring potential. For the other cases, pharmacological therapy is being the routine. The mostly used option is prednisone, a systemic corticosteroid administered orally. The therapeutic response to corticosteroids is variable and its effectiveness rates fluctuate between 30 to 84%. Clearly effective responses or just a reduction in the lesion's growth rate are possible. The effective response, when observed, occurs on average a week after the beginning of use of medication. Side effects are frequent, being the most common the cushingoid appearance, alterations of personality, hypertension, gastrointestinal disorders, decrease in growth speed and head circumference and weight gain.

    For cases with no response to the corticosteroid, the most frequently used drug as a second treatment line is subcutaneous alpha-interferon 2b. In spite of being very effective, this medication presents a higher rate of side effects, being spastic diplegia the most fearsome.

    Other drugs are being used, such as chemotherapeutic drugs and immunomodulators. However, published studies cover small casuistics, with no great population studies or long term follow up to justify its routine use.

    Recently, Léauté-Labrèze et al. reported the use of beta blockers (propanolol) for IH treatment. The casual finding of a significant reduction in hemangiomas volume was observed when this drug was used as an antihypertensive for the treatment of side effects resulting from the use of systemic corticoids in the treatment of infantile hemangioma. A significant reduction of tumor volume was observed after introduction of the beta blocker, in a short period of time, with stable results after the end of treatment, which suggested evidences of the benefits of this drug in the tumor treatment. Other authors also reported the successful use of the medication. Recent initial studies show the effectiveness of the isolated use of propanolol, suggesting the presence of specific action mechanisms for this medication.

    Beta blockers are being used in children for approximately 40 years, with proven clinical safety and no cases of death or cardiovascular disease resulting from its direct use. Side effects are already well established, such as bradycardia and transitory hypotension, requiring monitoring from the beginning of treatment. Besides, beta blockers reduce lipolysis, glycogenolysis and gluconeogenesis, predisposing to hypoglycaemia. It has to be used with special attention in neonates, who can present hypoglycaemia without medication.

    Beta blockers, and more precisely propanolol, appear as one more therapeutic option with apparent good results. So far in literature there are just some case reports and initial protocols about the use of this medication.

    Lesions located on the cervicofacial region with relative indication for treatment are more susceptible to visual exposure, causing discomfort to the patient and family, apart from the possibility of distortion of growing anatomical structures which will eventually evolve into deformities. The best management for these cases is debatable: on one hand the possibility of pharmacological treatment with corticosteroids with a variable success rate and significant side effects; on the other hand the conservative/ expectant treatment, in other words, waiting for evolution, expecting a complete spontaneous regression. Therefore, a drug with known reduced side effects could be a good alternative of treatment, accelerating tumor involution and allowing a quick problem solution in comparison to the expecting conduct and to the conventional pharmacological treatment.

    In this context, the proposal is to assess the use of propanolol in IH treatment, quantifying its effectiveness and safety under continuous monitoring and comparing it to the use of oral corticosteroid.

    In the present study we propose the assessment of the betablockers' use in comparison to the use of corticosteroids in infants with IH in the proliferative or involuting phases, with indication for clinical treatment, and that are not alarming nor urgent; in other words, the current relative indications for treatment.
