Judging from the situation you described, it is unknown whether there is any basis for lung adenocarcinoma, because you said that no pathological tissue was taken out and there was no pathological report. If you want to treat with Iressa, ask my opinion. I don't recommend you to treat with Iressa.
Because you are a male and have a history of smoking, the pathological diagnosis is unknown now, and it is difficult to predict whether Iressa treatment is effective, which will delay diagnosis and correct treatment and ultimately affect your life.
Iressa is not a panacea for lung cancer, it is not effective for small cell lung cancer, it is not effective for lung squamous cell carcinoma, and it is not effective for men and patients with smoking history. Even women, non-smokers and patients with adenocarcinoma need EGFR gene mutation to prolong their survival time, so don't just watch one-sided publicity on the Internet. Tell you a basic common sense, there is no panacea for tumor medical treatment. Iressa is a molecular targeted therapy, and only when there is a target can it be effective. The more molecular targeted therapies, the clearer the target.
I believe that local doctors in Yichang, especially those in oncology department, should give you the best advice. Within the scope of Hubei Province, the strength of tumor treatment in Yichang area is relatively strong, and the business study is also very tight. The oncology departments of Yichang Central Hospital and Yichang Second Hospital are also called Yichang Cancer Hospital. The oncology departments of Gezhouba Three Gorges Hospital have good oncology experts, such as Xu Xinhua, Grain Rain, Xin Li and Ke Hong. You can consult them nearby first.
(Dr. Zang Aihua solemnly reminds me that because I can't see the patient in person, I can't fully understand the condition. The above suggestions are for reference only. Please go to the hospital for specific diagnosis and treatment under the guidance of a doctor! )
