RESUMEN

PURPOSE: To evaluate the effect of hypofractionated radiation therapy (HFRT) of the breast/chest wall and regional nodes on overall survival (OS), disease-free survival (DFS), locoregional control and on treatment-related toxicity in patients with breast cancer and nodal involvement. METHODS AND MATERIALS: Two hundred fifty-seven patients treated between October 2009 and June 2011 with hypofractionated locoregional radiation therapy (42 Gy in 15 fractions) were retrospectively reviewed, 51 (19.8%) after breast-conserving surgery and 206 (80.2%) after radical surgery. Patients treated with breast-conserving surgery received a boost dose to the tumor bed (delivered by photons, electrons, or interstitial high-dose-rate brachytherapy). Two hundred fifty-six (99.6%) patients underwent chemotherapy, 209 (81.3%) had hormonal treatment, and 65 (25.3%) had anti-HER2 targeted therapy. RESULTS: The median follow-up time was 64 months (range, 11-88 months). The rates of 5-year OS, DFS, locoregional recurrence (LRR)-free survival, and distant metastasis (DM)-free survival were 86.6%, 84.4%, 93.9%, and 83.1%, respectively. In multivariate analysis (MVA), lymph node ratio >65%, lymphovascular invasion, and negative hormone receptor status predicted for OS, DSF, and DM. T3 to 4 stage was also associated with worse DFS and DM. Finally, for LRR the independent prognostic factors on MVA were N2 to 3 stage and grade 3. Hyperpigmentation was observed in 19.2% of patients, telangiectasia in 12.3%, and fibrosis in 30.7%. Grade ≥2 lymphedema was recorded in 5.8% of cases. During the study follow-up, no cardiac or symptomatic pneumonitis was observed, nor were plexopathy or rib fractures. CONCLUSION: According to the findings from this retrospective study, HFRT seems to be an acceptable alternative for patients with breast cancer who need regional nodal irradiation. However, prospective randomized trials are necessary to confirm these preliminary results.

RESUMEN

BACKGROUND: Although cervix carcinoma is one of the most common malignancies in women, hematogenous metastases are relatively not common. Cutaneous metastases, in particular, are unusual even at an advanced stage of disease. Their presence is a predictor of poor prognosis. CASE PRESENTATION: Case 1: A 63-year-old postmenopausal Moroccan woman was diagnosed as having cervical squamous cell carcinoma. She was treated with radical concurrent chemotherapy and radiation therapy followed by low-dose brachytherapy. Six months after finishing the therapy, multiple skin nodules appeared on her abdomen and chest wall. An excision biopsy was performed and showed metastatic squamous cell carcinoma. Her disease progressed and she died before completing her fourth course of palliative chemotherapy. Case 2: A 48-year-old Moroccan woman was diagnosed as having cervical squamous cell carcinoma; she was treated with concurrent chemoradiation. Before a planned high-dose brachytherapy, she noticed many nodular lesions on her arms, thighs, and chest wall. An excision biopsy was performed and showed metastatic squamous cell carcinoma. She then underwent a series of imaging examinations, including computed tomography of her chest, abdomen, and pelvis, and a whole body bone scan that showed disseminated disease involving her lungs and bones. She died after two courses of palliative chemotherapy, 2 months after the appearance of the skin lesions. CONCLUSION: We report two cases to illustrate a rare localization of metastasis from cervical carcinoma that is highly aggressive requiring early detection and aggressive management.

RESUMEN

BACKGROUND: Paragangliomas are neuroendocrine tumors derived from the extra-adrenal paraganglia of the autonomic nervous system. Only 3% of all paragangliomas are reported to occur in the head and neck region. The most common paraganglioma of the head and neck is the carotid body tumor. Only few cases have been described in the literature regarding the pediatric age group less than aged 14 years, mostly as case reports. CASE REPORT: Our case describes a massive paraganglioma in the head and neck region occurring in a 3-year-old Arabic boy, for which surgical excision was not possible and radiotherapy resulted in a good clinical and radiologic response. CONCLUSIONS: Paragangliomas a rare in children and mostly diagnosed in a locally advanced stage. Surgery in most cases is difficult especially because of the proximity of the vessels; radiotherapy is still a good alternative for those cases.

RESUMEN

Venous thromboembolism (VTE) is a major health problem among patients with cancer, its incidence in this particular population is widely increasing. Although VTE is associated with high rates of mortality and morbidity in cancer patients, its severity is still underestimated by many oncologists. Thromboprophylaxis of VTE now considered as a standard of care is still not prescribed in many institutions; the appropriate treatment of an established VTE is not yet well known by many physicians and nurses in the cancer field. Patients are also not well informed about VTE and its consequences. Many studies and meta-analyses have addressed this question so have many guidelines that dedicated a whole chapter to clarify and expose different treatment strategies adapted to this particular population. There is a general belief that the prevention and treatment of VTE cannot be optimized without a complete awareness by oncologists and patients. The aim of this article is to make VTE a more clear and understood subject.

RESUMEN

INTRODUCTION: Neurofibromatosis type 1, also known as Von Recklinghausen's disease, is a rare neuroectodermal disease that mainly affects the skin and the nervous system. Patients with neurofibromatosis type 1 have a higher risk of developing various types of cancers, especially tumors derived from the embryogenic neural crest. However, its association with breast cancer has seldom been reported. CASE PRESENTATION: We report the cases of three white Arabic women diagnosed with neurofibromatosis type 1, with a median age of 40-years-old (range: 39 to 43), who sought treatment at our centre for breast cancer. CONCLUSIONS: The association between neurofibromatosis type 1 and breast cancer is uncommon. In our case series we readdress this association through a literature review.
