Final answer:
The patient may undergo a right lower lung lobectomy via laparotomy, radiation therapy, chemotherapy, and/or immunotherapy for the treatment of adenocarcinoma of the right lower lung with brain metastasis.
Step-by-step explanation:
The treatment for adenocarcinoma of the right lower lung with brain metastasis typically involves a combination of different approaches. One commonly used procedure is right lower lung lobectomy via laparotomy, which involves surgical removal of the affected lobe of the lung to remove the tumor. Additionally, radiation therapy may be utilized to alleviate symptoms and prolong life, although it is not ordinarily curative for lung cancer. Furthermore, chemotherapy and immunotherapy are other treatment options that may be considered depending on the specific case and response of the patient.
