Background: In limited stage small cell lung cancer, involved field irradiation has been considered as standard. However, there have recent reports suggesting higher than expected nodal recurrence in the supraclavicular region. The study aimed to explore the reasonable radiotherapy range of supraclavicular zone for patients receiving prophylactic or radical radiation. Patients and methods: Supraclavicular zone was further divided into 4 zones, including upper pararecurrent laryngeal neural region (UP region), lower para-recurrent laryngeal neural region (LP region), medial supraclavicular region (MS region), and lateral supraclavicular region (LS region). And we analysed the distribution of lymph node metastasis in supraclavicular zone based on CT-images. Results: our data showed that metastases occurred most frequently in the medial supraclavicular region (42.8%), followed by the lower para-recurrent laryngeal neural region (40.6%), lateral supraclavicular region (9.4%), and upper para-recurrent laryngeal neural region (7.2%), respectively. Conclusion: If prophylactic irradiation therapy is considered, the target zones for prophylactic irradiation should include MS region and LP region as recommended.
BACKGROUND:
Bronchial anthracofibrosis is a common disease that has been reported in the past. We aim to summarize the clinical characteristics of bronchial anthracofibrosis combined with tuberculosis infection to reduce missed diagnosis.
METHODS:
The clinical features of two cases of bronchial anthracofibrosis combined with tuberculosis were analyzed retrospectively, and relevant studies were reviewed.
RESULTS:
The two patients were both elderly individuals who presented with chronic cough and expectoration. Pigmentation in the bronchus mucosa and stenosis of lumen were observed during bronchoscopy. Tuberculosis infection was confirmed by biopsy. The symptoms were remarkably relieved and no recurrence was found after anti-tuberculosis treatment.
CONCLUSION:
Bronchial anthracofibrosis may be combined with tuberculosis. To avoid misdiagnosis, we should be aware of possible tuberculosis infection when patients are diagnosed with bronchial anthracofibrosis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
