The role of radiotherapy (RT) as an adjuvant to surgical options in the treatment of locally advanced rectal cancer has been established as it reduces local recurrence when combined with surgical resection and enhances survival when used in multidisciplinary treatment. However, many issues need to be addressed; some of these can render RT unnecessary, whereas others can reveal a new role of RT in rectal cancer. This review will discuss not only the basic role of RT but also the associated but controversial issues in detail in an attempt to find answers and determine future directions for the next decade.

Study on 74 breast cancer patients after radiotherapy in K Hospital, Hanoi. Results: Vitexin capsule decreased the lesion of leukocyte cells after radiotherapy compared with control group. After radiotherapy, TCD4, TCD8 lymphocytes decreased statistical significantly in comparison with before treatment. After taking drug for 2 months (4 capsules/day, 100mg/capsule divided 2 times), the cells were being recovery with different levels, the number of TCD8 in Vitexin group was higher than those in the control group. The findings suggested that the Vitexin had ability to recover quickly the numerous of damaged immune cells during radiotherapy

A 61-year-old male diagnosed with laryngeal squamous cell carcinoma presented with hoarseness, progressive dysphagia leading to aspiration, and dyspnea one month after definitive radiation therapy. Examination revealed a diffusely swollen glottis, paralyzed vocal cords, and post-radiation fibrosis. Several glottic biopsies yielded results negative for malignancy and favored radiation-induced changes. When presented with the option of further diagnostic testing with a positron emission tomography (PET) scan or an outright laryngectomy, the patient decided on the latter. Final histopathologic diagnosis was negative for recurrence of malignancy. This case demonstrates treatment dilemmas for patients with laryngeal carcinoma with uncertain recurrence wherein radical surgical management may prove to be a viable option to achieve both diagnostic certainty and ultimate relief of symptoms.
