Squamous cell carcinoma of the larynx continues to be the commonest head and neck cancer in many Western countries. The larynx plays a key role for many essential functions, including breathing, voice production, airway protection, and swallowing. The goals of laryngeal cancer treatment are thus to provide best possible oncologic control, while optimizing functional outcomes.
In recent decades, the treatment paradigm for advanced laryngeal cancer has shifted from one of primary surgery (total laryngectomy) as gold standard, toward non-surgical organ-preserving treatment using radiotherapy or chemoradiotherapy. However, concerns have emerged regarding functional outcomes after chemoradiotherapy, as well as possible decreased overall survival in patients with laryngeal cancer.
The purpose of the present review is to review surgical and non-surgical options for treatment of advanced laryngeal cancer, as well as the evidence supporting each of these.
Head and neck cancers are the most common cancers in developing countries, especially in Southeast Asia. Head and neck cancers are more common in males compared to females. This is mainly attributed to tobacco, areca nut, alcohol, etc. Oral cancers are most common amongst all head and neck squamous cell cancers (HNSCC). HNSCC in the developing world differ from those in the Western world in terms of age, site of disease, etiology, and molecular biology. Poverty, illiteracy, advanced stage at presentation, lack of access to health care, and poor treatment infrastructure pose a major challenge in management of these cancers. The annual GDP (gross domestic product) spent on health care is very low in developing countries compared to the developed countries. Cancer treatment leads to a significant financial burden on the cancer patients and their families. Several health programs have been implemented to curb this rising burden of disease. The main aims of these health programs are to increase awareness among people regarding tobacco and to improve access to health care facilities, early diagnosis, treatment, and palliative care.
Oropharyngeal cancer represents a growing proportion of head and neck malignancies. This has been associated with the increase in infection of the oropharynx by oncogenic strains of human papillomavirus (HPV). Transoral robotic surgery (TORS) has opened the door for minimally invasive surgery for HPV-related and non-HPV-related oropharyngeal cancer. Compared to traditional open surgical approaches, TORS has been shown to improve functional outcomes in speech and swallowing, while maintaining good oncologic outcomes.
The incidence of oropharyngeal squamous cell carcinoma (OPSCC) has markedly increased over the last three decades mostly due to human papillomavirus (HPV)-related infections. Cancers resulting from HPV infection bear a better prognosis than those that are smoking-related. Because HPV-positive patients are often younger, with lower rates of co-morbid illness and longer overall life expectancies, long-term sequelae of therapy have become an important issue. Treatment of oropharyngeal cancers has typically involved the use of radiation and chemotherapy to avoid the morbidity of open surgery which included mandibulotomy and composite resection. Transoral robotic surgery (TORS) is an emerging treatment option for this disease, avoiding the morbidity of open approaches while providing excellent oncologic and functional outcomes. With overall survival rate at 2 years exceeding 80%, and local failure rate of less than 3%, patients receiving TORS report relatively good health-related quality of life (QOL) scores. The aim of the current review is to provide a summary of the current literature with regard to the oncologic and functional outcomes following treatment of OPSCC with TORS.
Background. Spermatocytic seminoma is a rare testicular malignancy, appearing in the adult population. It has a good prognosis and a low rate of metastatic potential.
Objectives. We present five cases diagnosed and treated with radiotherapy at Rambam Health Care Campus in Haifa, Israel.
Methods. Between 1974 and 1996, five patients with stage I spermatocytic seminoma were referred post-orchiectomy to the Northern Israel Oncology Center. All five patients presented with the typical pathological features of the spermatocytic variant of classic seminoma, and all were staged clinically and radiologically.
Results. Mean age at diagnosis was 44 years (range 30–58 years). Main symptoms included a palpable testicular mass and/or testicular enlargement. Mean duration of symptoms was 9 months (range 0.5–24 months). Three patients were irradiated to the para-aortic/ipsilateral iliacal lymph nodes (mean total dose 2,500 cGy), one patient with 4,000 cGy. One patient was irradiated to the bilateral iliacal lymph nodes (2,600 cGy). With a median follow-up of 15 years, four patients are alive with no evidence of disease or severe late side effects. One patient developed severe lymphedema and symptomatic peripheral vascular disease, stage IIA prostate carcinoma (hormonal and brachytherapy treatment) and a non-secretory hypophyseal adenoma (surgically removed); he died at the age of 75 due to severe peripheral vascular and coronary heart disease with no evidence of his first or second primaries.
Conclusions. Prognosis is excellent and does not differ from classic seminoma. As in the accumulated experience in early-stage, low-risk classic seminoma, we suggest surveillance as the preferred policy.
Purpose. This is a population study of patients who were treated for vulvar cancer in a tertiary center in northern Israel, aimed to report clinical findings, treatment, and outcome.
Methods. A retrospective chart review of all medical records of consecutive patients who were treated for vulvar cancer in the years 1993–2012 was conducted. Data extracted from the medical records included demographics, histology, size of lesion, stage of disease at diagnosis, type of treatment, radiation dose, follow-up, recurrence, and survival.
Results. The study included 44 patients with a median age of 69.8 years (range, 42–93 years). Thirty-five (79.5%) of the patients were of Jewish descent, five were Arabic, and four were of other descent. The most common histology type was squamous cell carcinoma in 35 (79.5%) patients. Most patients were staged FIGO II–III at time of diagnosis. Surgery was the most common primary treatment modality (54.2%). Twenty-three (52.2%) patients had recurrent disease. Older age and more advanced stage at diagnosis were associated with increased mortality.
Conclusion. Vulvar cancer is common among elderly women with co-morbidities who present in advanced disease stage; all these factors are significant for survival.
The Registro Informatizado de Enfermedad TromboEmbólica (RIETE Registry) is an ongoing, international, prospective registry of consecutive patients with acute venous thromboembolism (VTE) designed to gather and analyze data on treatment patterns and outcomes in patients with acute VTE. It started in Spain in 2001, and 6 years later the database was translated into English with the aim to expand the Registry to other countries. In contrast to randomized controlled trials, there is no imposed experimental intervention: the management is determined solely by physicians. Thus, it provides data on patients with VTE in a real-world situation with an unselected patient population. Data from RIETE are hypothesis-generating and provide feedback from real-world clinical situations. So far, we learned about the natural history of VTE in patients with relative or absolute contraindications to anticoagulant therapy. We also learned interesting aspects on the natural history of VTE, and we built a number of prognostic scores to identify VTE patients at low, moderate, or high risk for adverse outcome.
In the absence of immortality, the human species has over the millennia developed rites and rituals to help in the passing of life to honor the person who is dying or has died or in some way demonstrate their “courage” and perseverance as well as duty even in the face of almost certain death. The centuries-old traditions of the gathering of loved ones, the chanting of prayers, the ritual religious blessings are in the process of being replaced by the “miracles” of modern medical technology.
Thrombotic microangiopathies (TMAs) comprise a group of distinct disorders characterized by microangiopathic hemolytic anemia, thrombocytopenia, and microvascular thrombosis. For many years distinction between these TMAs, especially between thrombotic thrombocytopenic purpura (TTP) and hemolytic uremic syndrome (HUS), remained purely clinical and hard to make. Recent discoveries shed light on different pathogenesis of TTP and HUS. Ultra-large von Willebrand factor (UL-VWF) platelet thrombi, resulting from the deficiency of cleavage protease which is now known as ADAMTS-13 (a disintegrin and metalloproteinase with a thrombospondin type 1 motif, member 13), were found to cause TTP pathology, while Shiga toxins or abnormalities in regulation of the complement system causes microangiopathy and thrombosis in HUS. TMAs may appear in various conditions such as pregnancy, inflammation, malignancy, or exposure to drugs. These conditions might cause acquired TTP, HUS, or other TMAs, or might be a trigger in individuals with genetic predisposition to ADAMTS-13 or complement factor H deficiency. Differentiation between these TMAs is highly important for urgent initiation of appropriate therapy. Measurement of ADAMTS-13 activity and anti-ADAMTS-13 antibody levels may advance this differentiation resulting in accurate diagnosis. Additionally, assessment of ADAMTS-13 levels can be a tool for monitoring treatment efficacy and relapse risk, allowing consideration of therapy addition or change. In the past few years, great improvements in ADAMTS-13 assays have been made, and tests with increased sensitivity, specificity, reproducibility, and shorter turnaround time are now available. These new assays enable ADAMTS-13 measurement in routine clinical diagnostic laboratories, which may ultimately result in improvement of TMA management.
Pregnancy is a physiological hypercoagulable state, preparing the mother for the hemostatic challenge of delivery. However, this is associated with an increased risk of venous thrombosis and placenta-mediated complications, which present major challenges for mother and fetus. Although these conditions are heterogeneous in their pathophysiology, hereditary and acquired thrombophilia has been associated with recurrent pregnancy loss and gestational vascular complications, such as early-onset pre-eclampsia and placental abruption. Prevention of such placenta-mediated complications, which collectively complicate up to 15% of pregnancies, is a major issue for women’s health. Prospective interventional studies stratified by current knowledge of pathophysiological mechanisms related to placental and systemic hemostatic alterations will impact on the management of pregnancies at risk of these complications.
