Concomitant radiochemotherapy vs radiotherapy alone in patients with head and neck cancer

The primary objective of the present randomized phase III trial was to compare the 3-yr survival rate of patients treated with standard fractionated radiotherapy RT alone or with the same RT concomitantly with cisplatin DDP or carboplatin Cb. There were no significant differences in complete response rates between patients treated with RT alone or combined chemoradiotherapy. However, median time to progression TTP and overall survival OS were significantly longer in patients treated with concomitant chemoradiotherapy.

Thus, median TTP was 6. Similarly, median OS was At 3 yr follow-up, Patients treated with concomitant chemoradiotherapy experienced more frequently severe hematological toxicity. The present study clearly demonstrated that concomitant chemoradiotherapy with platinum analogs significantly prolongs 3-yr survival and median OS in patients with locally advanced HNC compared to conventional RT alone.

Treatment for patients with head and neck cancer requires a multidisciplinary approach. Radiotherapy is employed as a primary treatment or as an adjuvant to surgery. Each specific subsite dictates the appropriate radiotherapy techniques, fields, dose, and fractionation scheme. Quality of life is also an important issue in the management of head and neck cancer. The radiation-related complications have a tremendous impact on the quality of life. Modern radiotherapy techniques, such as intensity-modulated radiotherapy and image-guided radiotherapy, can offer precise radiation delivery and reduce the dose to the surrounding normal tissues without compromise of target coverage. In the future, efforts should be made in the exploration of novel strategies to improve treatment outcome in patients with head and neck cancer.

Radiotherapy for Head and Neck Cancer

Background : Locoregional recurrence is a predominant failure in locally advanced head and neck cancers despite of multimodality treatment including surgery and adjuvant chemoradiation. Analysis of locoregional failure pattern can contribute to improvement of future treatment. Objective : To evaluate pattern of failure in head and neck cancers treated with postoperative radiotherapy. Materials and Methods : Head and neck cancer patients who underwent postoperative radiotherapy in Thammasat hospital from October to January were retrospectively reviewed.

Frequency distribution of time elapsed from the diagnosis of head and neck cancer to the initiation of radiotherapy among patients with regional A and local B tumors. Frequency distribution of the number of radiotherapy treatments received by patients with regional A and local B tumors. Arch Otolaryngol Head Neck Surg. For each case, we calculated the timing and duration of radiotherapy using Medicare claims data.

Head and neck squamous cell carcinoma HNSCC accounts for more than , new cancer cases and over , deaths each year worldwide. After intrinsic tumour suppressor mechanisms fail, further tumour progression is the result of an inefficient elimination phase or equilibrium phase of the extrinsic tumour suppression by the immune system. Thus, they become invisible to immune cells by reducing the presentation of tumour antigens, decreasing their sensitivity to the cytotoxic effects of immune cells, and rendering their microenvironment immunosuppressive. Besides a well-known immunosuppressive effect of radiotherapy RT , it can also lead to positive alterations in innate and adaptive immunity. This combination was shown to cause similar toxicity compared to either RT or ICI alone across different cancer types.

Наконец она остановилась, и дверь открылась. Покашливая, Сьюзан неуверенно шагнула в темный коридор с цементными стенами. Она оказалась в тоннеле, очень узком, с низким потолком. Перед ней, исчезая где-то в темноте, убегали вдаль две желтые линии. Подземная шоссейная дорога… Сьюзан медленно шла по этому туннелю, то и дело хватаясь за стены, чтобы сохранить равновесие.

 - Хейл вздохнул и повернулся к своему компьютеру. В этом вся ее сущность. Блестящий криптограф - и давнишнее разочарование Хейла. Он часто представлял, как занимается с ней сексом: прижимает ее к овальной поверхности ТРАНСТЕКСТА и берет прямо там, на теплом кафеле черного пола. Но Сьюзан не желала иметь с ним никакого дела.

Как правильно ответить.

К несчастью, это был самый надежный способ собрать в шифровалке всех сотрудников Отдела обеспечения системной безопасности. После таких экстренных действий на главном коммутаторе раздавался сигнал общей тревоги. Проверку шифровалки службой безопасности Хейл допустить не. Он выбежал из помещения Третьего узла и направился к люку.

Невзламываемый шифр. Но это полный абсурд. Неужели Хейл никогда не слышал о принципе Бергофского.

 Господи Иисусе! - воскликнул водитель.  - С вами все в порядке. Мы уж думали, вы все погибли. Сьюзан посмотрела на него отсутствующим взглядом.

Когда я летел домой, - сказал он, желая переменить тему, - я позвонил президенту университета. Сьюзан радостно встрепенулась. - Скажи, что ты ушел с поста декана. Дэвид кивнул. - В следующем семестре я возвращаюсь в аудиторию.

В конце концов оно было найдено - так родился доступный широкой публике способ кодирования. Его концепция была столь же проста, сколь и гениальна. Она состояла из легких в использовании программ для домашнего компьютера, которые зашифровывали электронные послания таким образом, что они становились абсолютно нечитаемыми.
